Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the priority benefit of Taiwan
application serial no. 107132486, filed on Sep. 14, 2018. The
entirety of the above-mentioned patent application is hereby
incorporated by reference herein and made a part of
specification.
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The present invention relates to a clamping ring and a shell
structure having the same, and more particularly, to a clamping
ring holding a wire to prevent it from coming loose.
Description of Related Art
[0003] The existing electronic connector with waterproof function
undergoes a waterproof treatment mainly in the structure of two
regions, one is a region of the shell connected to a gap, and the
other is a joint of a wire and a wire hole of the shell.
[0004] The wire is bonded to the wire hole in the following manner.
The wire is correspondingly inserted into the wire hole of the
shell, and an external force is applied to push the wire inward,
such that the wire and the inner wall surface of the wire hole are
pushed against each other to be tightly adhered, thereby achieving
a sealing waterproof effect. However, the wire is mostly made of
elastic or soft materials. After long-term use, the tightness of
the wire to the wire hole may be reduced due to elastic fatigue or
artificial pull, and even separation of the wire from the shell may
occur. To alleviate this situation, a clamping ring is currently
used to clamp a side in which the wire passes into the shell, such
that the clamping ring holds and restricts the position of the wire
to increase the tightness of the wire to the wire hole and prevent
the wire and the wire hole from coming loose.
[0005] The rigidity of the joint between the clamping portions at
two sides and the top of the existing clamping ring is too high,
and the joint is prone to deformation and fracture during the
assembly process. The clamping portions at two sides of the
existing clamping ring are disposed in parallel in a straight line.
When the wire is clamped, the two clamping portions are also pushed
outward by the wire instead of clamping the wire flat. In this
case, the clamping portions at two sides always clamp the wire in a
pushed state, such that the stress of deformation is concentrated
at the aforementioned joint, thus causing the service life of the
clamping ring to be reduced such that deformation and fracture
occur prematurely.
[0006] Therefore, the development of a clamping ring that can
reduce deformation to improve the service life has become an
important development goal.
SUMMARY OF THE INVENTION
[0007] The present invention provides a clamping ring and a shell
structure having the same that can alleviate the fracture damage of
the clamping ring during the assembly process and the shortened
service life after the assembly process, thereby improving the
yield and service life of the finished product and avoiding the
shell structure and the wire from coming loose.
[0008] A shell structure of the present invention includes a
substrate, a side board, a connecting portion, a wire, and a
clamping ring. The side board is disposed at an edge of the
substance. The side board is extended upward along the edge of the
substrate and has an inner surface. The connecting portion is
disposed on the side board, and the connecting portion includes: a
first hole disposed at the outer surface of the side board; a
continuous wall extended toward the inner surface along the edge of
the first hole to form an accommodation space; a retaining wall
disposed at one end of the continuous wall adjacent to the inner
surface; a second hole disposed at the retaining wall and disposed
corresponding to the first hole, and the first hole is larger than
the second hole. The wire passes through the accommodation space,
wherein a portion of the wire is engaged with the retaining wall.
The clamping ring holds an end of the wire adjacent to the second
hole, the clamping ring is located outside the accommodation space,
and the outer diameter of the clamping ring is greater than the
aperture of the second hole. The clamping ring includes a
connecting beam and two engaging members. The two engaging members
are respectively disposed at two ends of the connecting beam, and
the connecting beam and the two engaging members are adapted to
accommodate and position the wire.
[0009] A clamping ring of the present invention includes a
connecting beam and two engaging members. The two engaging members
are respectively disposed at two ends of the connecting beam, and
the connecting beam and the two engaging members are adapted to
accommodate and position a wire. At least one of the two engaging
members has a curved portion, a column foot, and a hook. The curved
portion has an obliquely extended neck block. The neck block is
coupled to the corresponding end of the connecting beam, such that
the curved portion has a vertical distance with respect to the
connecting beam. The inside of the hollow groove forms the curved
portion. The column foot is coupled to the bottom of the curved
portion opposite to the neck block, and an angle is formed between
the column foot and the connecting beam. The hook is coupled to the
column foot, and a deforming groove is formed between the column
foot and the hook.
[0010] Based on the above, the clamping ring of the present
invention is adapted to be disposed in a shell structure of an
electronic adapter and to accommodate and position a wire passing
through the shell structure. The curved portion on at least one of
the engaging members of the clamping ring forms a hollow groove.
During the assembly process of the clamping ring, the clamping ring
is deformed by the extrusion of the wire, and the curved portion
can increase the amount of elastic deformation via the hollow
groove, reducing the stress acting on the curved portion, and
alleviating the fracture of the curved portion due to excessive
force to improve the yield of the assembled product. When the
clamping ring is assembled, the clamping ring accommodates and
clamps the wire, and the hollow groove of the curved portion can
also reduce the build-up of the clamping stress to increase the
service life of the clamping ring.
[0011] More specifically, a deforming groove is formed between the
column foot and the hook, and during the assembly process of the
clamping ring and the wire, the deforming groove causes the hook to
be elastically deformed toward the column foot, which also reduces
the stress acting on the engaging members and alleviates fracture
damage, etc. In addition, via the dispositions of the hollow groove
and the deforming groove, the material needed to make the clamping
ring can be reduced.
[0012] In order to make the aforementioned features and advantages
of the disclosure more comprehensible, embodiments accompanied with
figures are described in detail below.

FIG. 1E is an enlarged view of a connecting portion of the shell
structure of FIG. 1B.
[0025] The shell structure 100 of the present invention includes a
substrate 110, a side board 120, an upper cover 130, a circuit
element 140, a connecting portion 150, a wire 160, and a clamping
ring 200.
[0026] The substrate 110 is, for example, a plastic material that
is injection molded, and has a curved appearance. The side board
120 is formed by, for example, a molding method similar to the
substrate 110, and is disposed around an edge SE of the substrate
110, and the side board 120 is extended upward (an axis direction
AD) along the edge SE of the substrate 110 and has an inner surface
IS. In addition, the substrate 110 and the side board together form
a bearing space BS. The upper cover 130 is correspondingly disposed
in the side board 120 and abutted against the inner surface IS for
sealing the bearing space BS. The circuit element 140 is disposed
in the bearing space BS and is fixed on the substrate 110.
[0027] Referring to FIG. 1C to FIG. 1E, the connecting portion 150
is disposed on the side board 120, wherein the connecting portion
150 includes a first hole H1, a continuous wall 151, a retaining
wall 152, and a second hole H2.
[0028] The first hole H1 is disposed at an outer surface OS of the
side board 120. The continuous wall 151 is extended toward the
direction of the inner surface IS along the edge of the first hole
H1 and protruded from the inner surface IS of the side board 120 to
form an accommodation space AS. The retaining wall 152 is disposed
at one end of the continuous wall 151 adjacent to the inner surface
IS. In detail, the retaining wall 152 is vertically extended in the
continuous wall 151 and has an inner diameter smaller than the
inner diameter of the first hole H1. The second hole H2 is disposed
at the retaining wall 152 and linked to the accommodation space AS
and the bearing space
[0029] BS of the continuous wall 151. The second hole H2 is
disposed corresponding to the first hole H1, that is, the first
hole H1 and the second hole H2 have a common center point, and the
inner diameter of the first hole H1 is larger than the inner
diameter of the second hole H2.
[0030] The wire 160 passes through the accommodation space AS and
one end thereof passes into the bearing space BS, and a portion of
the wire 160 is engaged with the retaining wall 152. The wire 160
further includes a blocking portion 161, a positioning portion 162,
and a recess 163, which are integrally connected and sleeved on the
outer surface of the wire 160. The recess 163 is formed between the
positioning portion 162 and the blocking portion 161, and the
positioning portion 162 protrudes from the second hole H2 beyond
the retaining wall 152. In particular, the outer diameter of the
blocking portion 161 corresponds to the inner diameter of the first
hole H1, the outer diameter of the positioning portion 162
corresponds to the inner diameter of the second hole H2, and the
outer diameter of the recess 163 is smaller than the outer diameter
of the positioning portion 162.
[0031] More specifically, the retaining wall 152 has a fixing block
BL protruding from the retaining wall 152 and extended toward the
center point of the second hole H2, and the fixing block BL is
disposed corresponding to the positioning portion 162 of the wire
160. In particular, the positioning portion 162 has a positioning
groove PG corresponding to the fixing block BL. The wire 160 can
correspondingly pass through the connecting portion 150 only when
the positioning groove PG of the positioning portion 162 is aligned
with the fixing block BL.
[0032] In detail, the wire 160 is mounted, for example, from the
first hole H1 on the outer surface OS of the side board 120, and
sequentially passes through the positioning portion 162, the recess
163, and the blocking portion 161. The positioning groove PG of the
positioning portion 162 is aligned with the fixing block BL and
passes through the second hole H2, and the recess 163 also passes
through the second hole H2 with the positioning portion 162. At the
same time, the blocking portion 161 enters the accommodation space
AS from the first hole H1 and is in contact with the continuous
wall 151, and lastly the blocking portion 161 is closely adhered by
the blocking of the retaining wall 152, and the accommodation space
AS is completely filled by the blocking portion 161 to achieve the
object of sealing the connecting portion 150.
[0033] FIG. 2A is a schematic showing the separation state of a
clamping ring and a wire according to an embodiment of the present
invention. FIG. 2B to FIG. 2C are diagrams showing the assembly
process of the clamping ring and the wire of FIG. 2A. FIG. 2D is a
schematic showing the holding state of the clamping ring and the
wire of FIG. 2A.
[0034] Referring to FIGS. 2A and 2D and FIG. 1B to FIG. 1E, a
clamping ring 200 clamps an end of the wire 160 adjacent to the
second hole H2, the clamping ring 200 is located outside the
accommodation space AS, and the outer diameter of the clamping ring
200 is larger than the aperture of the second hole H2. The clamping
ring 200 includes a connecting beam 210 and two engaging members
220. The front side of the connecting beam 210 has a protrusion
211, and a spacing distance SD of the protrusion 211 with respect
to two ends EP is the same. In particular, the protrusion 211 is
used to engage with the positioning groove PG of the positioning
portion 162 of the wire 160.
[0035] The two engaging members 220 are respectively disposed at
the two ends EP of the connecting beam 210, and the connecting beam
210 and the two engaging members 220 are adapted to accommodate and
position a wire. More specifically, the clamping ring 200 is
disposed in the bearing space BS, and the connecting beam 210 and
the two engaging members 220 of the clamping ring 200 are clamped
on the recess 163 of the wire 160 to restrict the wire 160 to
within the bearing space BS, which prevents the wire 160 from being
detached from the connecting portion 150.
[0036] At least one of the two engaging members 220 of the clamping
ring 200 (two engaging members 220 are shown in the figures)
includes a curved portion 221, a column foot 222, a hook 223, a
restricting column 224, and an abutting portion 225.
[0037] The curved portion 221 has an obliquely extended neck block
NB, and the neck block NB is coupled to the corresponding end EP of
the connecting beam 210. In detail, the neck block NB is extended
toward an obliquely upward direction from the corresponding end EP
such that the curved portion 221 has a vertical distance D1 with
respect to the connecting beam 210. More specifically, the inside
of the curved portion 221 forms a hollow groove HG, and the hollow
groove HG is adapted to reduce the stress concentration of the
curved portion 221 during deformation, thereby increasing the
amount of elastic deformation of the curved portion 221. More
specifically, the neck block NB can prevent the issue in which
fracture occurs due to insufficient material thickness of the
curved portion 221 from the hollow structure design on the inside
of the curved portion 221.
[0038] The column foot 222 is coupled to the bottom of the curved
portion 221 opposite to the neck block NB, and an angle A is formed
between the column foot 222 and the connecting beam 210. In the
present embodiment, the angle A between the column foot 222 and the
connecting beam 210 is exemplified by 90 degrees. In other
embodiments, the user can adjust the proper angle of the column
foot and the connecting beam according to the shape and size of the
wire to be clamped, and the angle range is, for example, greater
than 0 degrees and less than 180 degrees, and the angle of the
present invention is not restricted to 90 degrees.
[0039] The hook 223 is coupled to the inside of the column foot 222
and is located below the neck block NB. The restricting column 224
is coupled to the hook 223 and is extended toward the neck block NB
of the curved portion 221. As a result, a deforming groove DG is
formed between the restricting column 224 and the column foot 222.
The deforming groove DG is adapted to move the restricting column
224 toward the column foot 222 when the hook 223 is deformed. The
abutting portion 225 is coupled between the restricting column 224
and the column foot 222, and the abutting portion 225 is adapted to
withstand and mitigate the stress generated by the deformation of
the hook 223.
[0040] The hook 223 has a support surface SS and a guide surface
GS. The support surface SS is disposed between the restricting
column 224 and a restricting end PE of the hook 223, and the
support surface SS is concave. Moreover, a portion of the support
surface SS is, for example, parallel to the connecting beam 210,
which facilitates the support of the wire 160 to be clamped. In
detail, the connecting beam 210, the restricting column 224, and
the support surface SS constitute a clamping space CS (see FIGS. 2A
and 2B), and the clamping space CS is adapted to accommodate and
clamp the wire 160.
[0041] The guide surface GS is disposed at a side of the hook 223
away from the column foot 222 and located below the restricting end
PE. In particular, a horizontal distance D2 of the guide surface GS
opposite to the restricting column 224 is gradually increased
toward the direction of the connecting beam 210. Referring to FIG.
2A and FIG. 1C, the spacing between the two guide surfaces GS is
tapered to guide the wire 160 to be clamped into the clamping space
CS.
[0042] More specifically, each of the hooks 223 has a through hole
TH disposed below the corresponding deforming groove DG, the
through hole TH is adapted to be sleeved on an additional
positioning column 300, and via the restricting effect of the
through hole TH, the clamping ring 200 can be prevented from
turning clockwise or counterclockwise.
[0043] Referring to FIG. 2A, the two engaging members 220 of the
present embodiment may respectively include the curved portion 221,
the column foot 222, the hook 223, the restricting column 224, and
the abutting portion 225 above, and are symmetrically disposed to
each other.
[0044] Referring to FIG. 2B and FIG. 1D, the clamping ring 200 of
the present embodiment is adapted to be disposed in the shell
structure 100 and to clamp and position the wire 160. The detailed
assembly process is explained below. The user grabs the clamping
ring 200 and moves toward the wire 160 along a vertical direction
VD. When the guide surfaces GS of the two hooks 223 are abutted
against and begins to guide the wire 160, each of the hooks 223 is
subjected to the pushing of a first stress F1 of the wire 160 to be
elastically deformed, and drives two of the restricting columns 224
toward two of the column feet 222 such that the deforming groove DG
is compressed. Since each of the hooks 223 is elastically deformed,
a second stress F2 from the pushing of the wire 160 is acted on the
abutting portion 225.
[0045] Referring to FIG. 2C and FIG. 1D, after the wire 160 passes
through two of the guide surfaces GS, the first stress F1 is acted
on two of the restricting ends PE to push two of the hooks 223 and
two of the column feet 222 relatively far apart. At this time, a
third stress F3 generated by the pushing of the wire 160 is acted
on the inside of each of the curved portions 221, and the two
column feet 222 are driven outward away from the neck block NB by
the hook 223, such that each of the curved portions 221 is
elastically deformed to expand each of the hollow grooves HG. At
the same time, a fourth stress F4 generated by the pushing of the
wire 160 is acted on the joint of the connecting beam 210 and the
two of the neck blocks NB, causing the neck blocks NB to expand
outward with respect to the connecting beam 210.
[0046] Referring to FIG. 2D, after the wire 160 passes through the
two restricting ends PE, the wire 160 enters the clamping space CS
of the clamping ring and the stresses (F1 to F4) acting on various
parts of the clamping ring 200 are all canceled out due to the
assembly of the wire 160. Thus, the curved portion 221, the column
foot 222, and the hook 223 are all returned to the original
position. At this time, the support surface SS of each of the hooks
223 carries the recess 163 of the wire 160, and the protrusion 211
of the connecting beam 210 is engaged with the positioning
groove
[0047] PG of the positioning portion 162. Lastly, the clamping ring
200 is clamped on the recess 163 and restricted by the protrusion
211 to prevent the wire 160 from coming loose or being separated
from the connecting portion 150 of the shell structure 100 by
external force pulling.
[0048] The specific effects of the clamping ring of the present
invention are described below. First, the clamping space of the
clamping ring of the present invention has a concave structure and
conforms to the shape of the wire. Unlike the planar disposition of
existing clamping rings, the situation in which stress is
excessively concentrated when the clamping ring holds the wire due
to the difference in shape can be avoided. Secondly, the clamping
ring of the present invention has a hollow portion and an abutting
portion, which can alleviate some of the stress concentrated
between the connecting beam and the column foot during the assembly
process of the conventional clamping ring and shift the stress to
between the end of the connecting beam and the neck block and to
the abutting portion so as to disperse the stress on the curved
portion. As a result, the chance of fracture to the curved portion
is reduced, thereby increasing the service life thereof. Thirdly,
the clamping ring of the present invention has a diagonally
extended neck block. As a result, the material thickness of the
curved portion is not insufficient due to the hollow structure
design on the inside of the curved portion of the present
invention, and therefore fracture does not readily occur.
[0049] Based on the above, the clamping ring of the present
invention is adapted to be disposed in the shell structure of an
electronic adapter and to accommodate the wire positioned through
the shell structure. The curved portion on at least one of the
engaging members of the clamping ring forms a hollow groove. During
the assembly process of the clamping ring, the clamping ring is
deformed by the extrusion of the wire, and the curved portion can
be elastically deformed by the hollow groove to reduce the stress
acting on the curved portion. As a result, fracture of the curved
portion due to excessive force can be alleviated to improve the
yield of the assembled product. When the clamping ring is
assembled, the clamping ring accommodates and clamps the wire, and
the hollow groove of the curved portion can also reduce the
build-up of the clamping stress to increase the service life of the
clamping ring.
[0050] More specifically, a deforming groove is formed between the
column foot and the hook, and during the assembly process of the
clamping ring and the wire, the deforming groove causes the hook to
be elastically deformed toward the column foot, which also reduces
the stress acting on the engaging members and alleviates fracture
damage, etc. In addition, via the dispositions of the hollow groove
and the deforming groove, the material needed to make the clamping
ring can be reduced.
[0051] Although the present invention has been described with
reference to the above embodiments, it will be apparent to one of
ordinary skill in the art that modifications to the described
embodiments may be made without departing from the spirit of the
present invention. Accordingly, the scope of the present invention
is defined by the attached claims not by the above detailed
descriptions.
