BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The invention relates to a cable bridle, a cable bridle
mechanism and a swapping system using the same.
Description of Related Art
[0003] With rapid development of information technology, computer
hardware equipments have been constantly reformed in response to
various changes. For example, in the early stage computers, the
hard disk is installed inside a host housing of the computer. Yet,
for the purpose of data storage or backup, or on basis of data
portability and security measure, the so-called "mobilerack" (e.g.,
a hard disk tray) has been developed based on demands to provide
users greater convenience. Furthermore, in the existing servers, a
swapping system is also widely applied because of aforesaid
advantages.
[0004] Hereinafter, the hard disk in the server is taken as an
example. In general, to avoid entangled information cables in the
space inside a computer system due to complex layout, the swapping
hard disk module in conventional art adopts a back plate to
organize data signals from multiple hard disks by simplified cables
for transmission, so as to reduce loss of the cables. However, the
back plate means higher cost and potential risk of damage. The
reason is that, in addition to the circuitry layout, it also
requires a considerable amount of connects. Specific connectors
must be disposed at the inside the back plate for connecting to the
corresponding data ports of the hard disks, and additional connects
are also required at the outside of the back plate for outputting
signals. Moreover, with increases in plugging times, it is
inevitably that damage and deviation will occur on the ports and
pins of the hard disk and the connectors to reduce the durability
of the swapping hard disks, resulting in reduction of the overall
durability of the system.
[0005] Based on the above, it has indeed become a problem to be
considered and solved for person skilled in the art as how to use
simple structure configuration to reduce the loss of the cables
while satisfying the motion mechanism of the swapping structure as
mentioned above.
SUMMARY OF THE INVENTION
[0006] The invention is directed to a cable bridle, a cable bridle
mechanism and a swapping system using the same, which are capable
of properly receiving and releasing the cable connected between
different devices in the swapping system.
[0007] A swapping system of the invention includes a first device,
a second device, a cable, and at least one cable bridle. The first
device has a receiving space. The second device is movably disposed
in the receiving space for moving into or moving out of the first
device. The cable located in the receiving space is electrically
connected between the first and the second devices. The cable is
received or released according to a relative motion of the first
and the second devices. The cable bridle is disposed on the cable.
The second device is moved into the first device so that the cable
is received, and the cable is constrained by the at least one cable
bridle to form at least one bending when the cable is received.
[0008] A cable bridle mechanism of the invention is adapted to a
cable. The cable bridle mechanism includes a track, a moving member
and at least one cable bridle. The track has a path. The moving
member is movably coupled to the track to move along the path, and
the moving member has a buckling slot. The cable bridle has a body
and at least one first buckling portion. The first buckling portion
extends from the body to be buckled to the cable. The body has a
second buckling portion facing away from the first buckling
portion. The second buckling portion is engaged with the buckling
slot to secure the body on the moving member. When the cable is
received or released, the cable drives the cable bridle and the
moving member to move along the path of the track and form a
bending on a place where the cable and the body are buckled.
[0009] A cable bridle of the invention is adapted to a cable. The
cable is electrically connected between a first device and a second
device. The first device and the second device are movably
assembled together. The cable is received or released according to
a relative motion of the first device and the second device. The
cable bridle includes a body and at least one first buckling
portion. The first buckling portion extends from the body. The
first buckling portion is buckled to the cable so that the body is
contacted against the cable. When the cable is received or released
according to the relative motion of the first device and the second
device, the cable is constrained by the body to form a bending.
[0010] Based on the above, in the swapping system according to the
invention, the cable bridles are disposed on the cable between two
different devices. Accordingly, when said two devices are moved
close to or away from each other by the relative motion, the cable
can be constrained by the cable bridles to form at least one
bending so that the cable can form a structure with multiple
stacked sections due to the bendings when said two devices are
moved close to each other to thereby achieve the effect of
receiving.
[0011] To make the above features and advantages of the present
disclosure more comprehensible, several embodiments accompanied
with drawings are described in detail as follows.

DESCRIPTION OF THE EMBODIMENTS
[0021] Reference will now be made in detail to the present
preferred embodiments of the invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, the
same reference numbers are used in the drawings and the description
to refer to the same or like parts.
[0022] FIG. 1 is a schematic diagram illustrating a partial
structure of a swapping system according to an embodiment of the
invention, in which a storage state of the swapping system is
illustrated. FIG. 2 is a schematic diagram illustrating another
state of the swapping system depicted in FIG. 1, in which an
unfolding state of the swapping system is illustrated. FIG. 3 is a
block diagram of the swapping system depicted in FIG. 1, in which
an electrical connection relationship of related members of the
swapping system is illustrated. Herein, a swapping case structure
of the server is used as an example for the description, but the
present embodiment is not limited thereto.
[0023] Referring to FIG. 1, FIG. 2 and FIG. 3 together, in the
present embodiment, a swapping system 100 includes a first device
110, a second device 120, a cable 130 and a cable bridle 140. It
should be noted that, the first device 110 is a host system of the
server for example, which has a control unit 116, and the second
device 120 is a swappable device (e.g., multiple electronic
components such as disk drives, circuit boards or an array thereof)
mounted on the host system for example. Herein, as shown in FIG. 1
and FIG. 2, the second device 120 has the characteristic of a
drawer structure, on which a plurality of sub units A1 to A6 (i.e.,
those illustrated in dashed line contour) may be disposed and
served as representative of a disk drive array. Further, the second
device 120 can be movably disposed in a receiving space 112 of the
first device 110 through a sliding track 114, so as to move into or
move out of the receiving space 112 in X-axis. Accordingly, the
user can pull the second device 120 out from the receiving space
112 through the drawer structure for replacing or maintaining the
sub units A1 to A6, and push the second device 120 back to the
receiving space 112 after said operations are completed.
[0024] The cable 130 is located in the receiving space 112 and
electrically connected between the first device 110 and the second
device 120 for supplying power to the sub units A1 to A6 from the
host system (the control unit 116 of the first device 110) or
signal transmission. Accordingly, the cable 130 will be received or
released (i.e., a receiving state depicted in FIG. 1 and a
releasing state depicted in FIG. 2) according to a motion status of
the second device 120 relative to the first device 110. In order to
successfully move the second device 120 out of the receiving space
112 and replace the sub units A1 to A6 under an uninterrupted power
state, a length of the cable 130 must satisfy a length required for
moving the second device 120 out of the receiving space 112. As
such, it is required to provide sufficient space, structure and
method for storing the cable 130 when moving the second device 120
into the receiving space 112.
[0025] Based on the above, the present embodiment adopts the cable
bridle 140 disposed on the cable 130 so that the cable 130 is
constrained by the cable bridle 140 to form at least one bending
when the second device 120 is moved into the receiving space 112 of
the first device 110. As such, the cable 130 may be received to
accomplish the goal of storing the second device 120 inside the
first device 110 without causing entanglement or interfering on the
cable 130. Conversely, when the cable 130 is released or unfolded
according to the relative motion of the first device 110 and the
second device 120, the cable 130 may be unfolded based on the
bending. Accordingly, as shown in FIG. 1, the present embodiment
adopts the cable bridles 140 disposed on multiple positions on the
cable 130, so as to form a plurality of bendings at the fixed
positions and accordingly achieve the purpose of receiving and
releasing.
[0026] More specifically, the cable bridles 140 of the present
embodiment can also be movably disposed on the first device 110
along a path X1, so that the cable 130 may be successfully
received. Accordingly, when the cable 130 is received or released
according to the relative motion of the first device 110 and the
second device 120, a plurality of portions on the cable 130 (i.e.,
portions on which the cable bridles 140 are respectively disposed)
are constrained to move back and forth on the path X1. That is to
say, with use of the cable bridles 140 on the cable 130, the
portions of the cable 130 can move according to the fixed path X1,
such that bendings formed on the fixed positions (the positions
where the cable bridles 140 are respectively disposed) on the cable
130 can move along the path X1 towards the inside of the first
device 110 when the second device 120 is moved into the receiving
space 112. Therefore, the cable 130 is bent into multiple sections,
and these sections may be stacked and received one by one, so that
the cable 130 may be successfully stored between the first device
110 and the second device 120. On the other hand, when the second
device 120 is moved out of the receiving space 112, the bendings
formed on the fixed positions (the positions where the cable
bridles 140 are respectively disposed) of the cable 130 also
gradually move along an reversed direction of the path X1 (in a
positive X-axis direction) towards the outside of the first device
110, so that the cable 130 may be successfully released or
unfolded.
[0027] FIG. 4 and FIG. 5 are explosion diagrams illustrating part
of the members in the swapping system depicted in FIG. 1
respectively from different perspectives. Referring to FIG. 1 and
FIG. 2, and FIG. 4 and FIG. 5 together, in the present embodiment,
the swapping system 100 further includes a track 150, a moving
member 160 and a fixing member 170. The track 150 is disposed in
the receiving space 112 of the first device 110, and an extending
direction of the track 150 is identical to the path of the motion
of the second device 120 relative to the first device 110 (i.e.,
the two are parallel), that is, the track 150 has aforesaid path
X1. The fixing member 170 is disposed on one end of the track 150,
such that a fixed position of the cable 130 is formed for bending
and to serve as a fixed end when the cable 130 is received or
released.
[0028] As shown in FIG. 4 and FIG. 5, the moving member 160
includes a carrier 162, a riveting member 164 and a riveting hole
168. The riveting member 164 passes through the riveting hole 168
on the carrier 162 to be engaged with a track trench 152 of the
track 150 so that the carrier 162 is movably combined with the
track 150. The moving member 160 further includes a buckling slot
166. The cable bridle 140 can be engaged with the moving member 160
through the buckling slot 160 so as to fix the cable bridle 140 on
the moving member 160. More specifically, as shown in FIG. 5, the
cable bridle 140 further includes a second buckling portion 146,
which is configured to be engaged with the buckling slot 166 of the
moving member 160 to fix a body 142 of the cable bridle 140 onto
the moving member 160.
[0029] Accordingly, the cable bridle 140 can move back and forth on
the track 150 according to the moving member 160, so that the
specific positions (i.e., where the cable bridles 140 are disposed)
of the cable 130 can move back and forth along the path X1 depicted
in FIG. 1 and FIG. 2 when the cable 130 is driven to be received or
received according to the motion of the second device 120 relative
to the first device 110. In other words, a cable bridle mechanism
constituted by the track 150, the moving member 160 and the cable
bridle 140 in the present embodiment is capable of providing
effects of constraining and folding the cable 130 between the first
device 110 and the second device 120 with relative motion in the
swapping system 100.
[0030] FIG. 6 and FIG. 7 are schematic diagrams respectively
illustrating the cable bridle in different states. Referring to
FIG. 6 and FIG. 7 together, specifically, the cable bridle 140
includes the body 142 and a first buckling portion 144. The first
buckling portion 144 extends from the body 142 and is used to be
buckled to the cable 130 so that the body 142 can be contacted
against the cable 130, whereas the second buckling portion 146
extends from a main portion 142a and faces away from the first
buckling portion 144. In the present embodiment, the body 142 is a
flexible sheet (e.g., a plastic sheet) divided into the main
portion 142a and a plurality of sub portions 142b extended from the
main portion 142a. The first buckling portion 144 includes an
engaging protrusion 144c and an opening 144d, which are
respectively disposed at two of the sub portions 142b located on
two opposite sides of the main portion 142a and corresponding to
each other. Accordingly, the two of the sub portions 142b
corresponding to each other are respectively bent relative to the
main portion 142a to be partially overlapped, such that the two of
the sub portions 142b are buckled together due to the engaging
protrusion 144c being passed through and engaged with the opening
144d while the cable 130 is secured therein. As a result, the main
portion 142a of the body 142 may be attached on the cable 130.
[0031] Furthermore, the cable bridle 140 of the present embodiment
is in an unstressed state when being bent, and may generate an
elastic deformation by force when the cable 130 is pulled straight.
Therefore, when the second device 120 is moved into the receiving
space 112 so that the cable 130 is received, an elastic restoring
force of the cable bridle 140 can drive the cable 130 to bend at
the positions where the cable 130 is attached by the main portion
142a. Accordingly, the cable 130 may be successfully bent and
stacked at each of the positions where the cable bridles 140 are
buckled in order to achieve the effect of receiving. Also, as shown
in FIG. 1 and FIG. 2, in the cable 130 of the present embodiment,
the cable bridles 140 are assembled on the moving members 160 and
spaced apart from each other. That is to say, the cable 130 forms
two types of bending because of the cable bridle 140, where one
type of bending is formed due to the cable bridle 140 being
assembled to the moving member 160, whereas another type of bending
is in a free end state to maintain the freedom of the cable 130
when being received or released.
[0032] In addition, the body 142 further includes a trench 148,
which is located on the main portion 142a and faces away from the
second buckling portion 146. In terms of structure, the trench 148
can maintain elasticity and structural strength of the body 142
while allowing the body 142 to achieve a bending state as shown in
FIG. 7.
[0033] However, it is not intended to limit related structure of
the cable bridle 140 coupled to the first device 110 herein. That
is, in another embodiment not illustrated, the cable bridle on the
cable can be directly and slidably coupled to a bottom plate of the
first device, so that the cable can be received or released
according to a motion status of the cable bridle on the first
device. Furthermore, the present embodiment is not intended to
limit an amount of the cable bridles and the positions of the cable
bridles disposed on the cable, which may be decided based on the
environment and the requirements in use. That is, users may dispose
the cable bridles on proper positions of the cable according to the
length of the cable and a space between the first device and the
second device. Moreover, the present embodiment is not intended to
limit a form and an amount of the first buckling portions, any
known buckling structure in the conventional technology capable of
allowing the body of the cable bridle to tightly contact with the
cable is suitable for the present embodiment.
[0034] FIG. 8 is a schematic diagram illustrating a portion of a
swapping system according to another embodiment of the invention.
FIG. 9 is a schematic diagram illustrating the cable bridle in the
swapping system depicted in FIG. 8. The following description may
refer to FIG. 8 and FIG. 9 together with reference to FIG. 1 and
FIG. 2 of the foregoing embodiment. In the present embodiment,
unlike the foregoing embodiment, a cable bridle 240 includes a body
242 and a first buckling portion 244, whereas a second buckling
portion 246 extends and faces away from the first buckling portion
244. Furthermore, the first buckling portion 244 includes a contact
protrusion 244b and an elastic locking hook 244a, which are
respectively disposed on the body 242. The elastic locking hook
244a is engaged with the contact protrusion 244b so that the cable
130 passes through in between the body 242, the contact protrusion
244b and the elastic locking hook 244a. The elastic locking hook
244a is adapted to generate an elastic deformation by force to be
released from the contact protrusion 244b. Accordingly, the cable
130 can also generate the bending through the cable bridle 240 and
move along the track 150 according to the moving member 160 to be
successfully received or released (unfolded), so as to accomplish
the same effects of the foregoing embodiment.
[0035] FIG. 10 is a schematic diagram illustrating a cable bridle
mechanism according to yet another embodiment of the invention.
Referring to FIG. 10, in the cable bridle mechanism of the present
embodiment, unlike the foregoing embodiment, at least part of a
track 350 is an arc line, and the moving members 160 and the cable
bridle 140 (only part of them is shown herein) disposed on the
track 350 are identical to those in the foregoing embodiment.
Practically, except for the fixing member 170, the rest of the
moving members 160 can all move along the different paths X1 and X2
of the track 350 during the process in which the cable 130 is
received or released. By doing so, the cable bridle mechanism of
the present embodiment is not limited to the swapping system only
capable of performing straight line motion. That is, by changing
the paths of the track 350, the cable bridle mechanism can be
adapted to two devices with different motion paths to increase its
applicability. In addition, a pivoting element (not illustrated)
may also be disposed between the moving member 160 and the track
350, so that the moving member 160 can pivot in relative to the
track 350 accordingly when the path is changed, so as to
effectively avoid interferences from being generated with the track
350.
[0036] In summary, in the swapping system according to the
foregoing embodiments of the invention, the cable bridles are
disposed on the cable between two different devices. Accordingly,
when said two devices are moved close to or away from each other by
the relative motion, the cable can be constrained by the cable
bridles to form at least one bending so that the cable can form a
structure with multiple stacked sections due to the bendings when
said two devices are moved close to each other to thereby achieve
the effect of receiving.
[0037] Furthermore, at least part of the cable bridles can be
coupled to one of the devices, or correspondingly disposed on the
moving member and the track, so that the portions of the cable
where the bendings are formed can be received or released one by
one when the relative motion of the two devices occurs.
Accordingly, the multiple stacked sections of the cable may be
sequentially formed without generating interferences with other
members. This also prevents the cable from overly large tension and
stress when the cable is bent or extended due to the motion of the
devices. As a result, the swapping system can be moved and
maintained in the uninterrupted power state to thereby increase the
durability.
[0038] Although the present disclosure 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
disclosure. Accordingly, the scope of the disclosure will be
defined by the attached claims and not by the above detailed
descriptions.
