Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to a shielding
device, and more particularly to a shielding device with high
torque.
[0003] 2. Description of the Related Art
[0004] FIGS. 1A and 1B show a conventional shielding device 10,
which is affixed to a circuit board by means of soldering. The
shielding device 10 includes a frame body 11 connected with a
connector 12 for signal input/output. The frame body 11 is formed
with a connection hole 13 for receiving therein an end protrusion
14 of the connector 12. After the end protrusion 14 is fitted into
the connection hole 13, the end protrusion 14 is riveted to connect
the connector 12 with the frame body 11. The frame body 11 and the
connector 12 are simply connected by means of riveting so that the
shielding device 10 can only have a torque value up to 30.about.40
kg-cm. This only meets the requirement for low torque
specification, while failing to meet the high torque specification
regulated by Society of Cable Television Engineers (SCTE), which is
over 41 kg-cm.
[0005] To overcome the above problem, the junction between the
frame body 11 and the connector 12 can be manually welded to
increase the torque of the conventional shielding device. However,
such solution will lead to deformation of the frame body 11.
Moreover, the additional reinforcing operation will cause extra
cost and increase of working time.
SUMMARY OF THE INVENTION
[0006] A primary object of the present invention is to provide a
shielding device with high torque.
[0007] To achieve the above and other objects, shielding device of
the present invention includes a frame body and a connector. The
frame body is composed of multiple sideboards. One of the
sideboards is formed with a receiving hole and at least three
arcuate slots formed around the receiving hole. The connector has a
main body section, a connection end section and at least three
arcuate protrusions. The three arcuate protrusions are formed on an
end face of the main body section at a front end of the connector
corresponding to the arcuate slots. The arcuate protrusions are
installed into the arcuate slots of the frame body and then riveted
to securely connect the connector with the frame body. The arcuate
protrusions of the connector are assembled in the arcuate slots of
the frame body to securely connect the connector with the frame
body, whereby the shielding device can have a torque value over 60
kg-cm. The shielding device of the present invention meets the
requirement for high torque specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Please refer to FIG. 2. The shielding device 20 of the
present invention includes a frame body 21 mountable on a circuit
board. The frame body 21 is connected to a connector 30 for signal
input/output.
[0017] The configuration of the frame body 21 can be designed
according to the requirement of the manufacturer. In this
embodiment, the frame body 21 has the form of a rectangular solid.
The frame body 21 is composed of four sideboards 22. One of the
four sideboards 22 is formed with a receiving hole 23 and at least
three arcuate slots 24. As shown in FIGS. 3 and 4, the three
arcuate slots 24 are formed around the receiving hole 23 at equal
intervals.
[0018] The connector 30 has a main body section 31, a connection
end section 32 and multiple arcuate protrusions 33. Referring to
FIGS. 3 and 5, there are three arcuate protrusions 33 formed on an
end face of the main body section 31 at a front end of the
connector 30 corresponding to the arcuate slots 24. The arcuate
protrusions 33 can be installed into the arcuate slots 24 of the
frame body 21 and then riveted to securely connect the connector 30
with the frame body 21 as shown in FIG. 2.
[0019] An outer surface of the connection end section 32 is formed
with a thread for locking with a coupling connector and
mechanically and electrically connecting with the coupling
connector.
[0020] The present invention is characterized in that the three
arcuate protrusions 33 of the connector 30 are assembled in the
three arcuate slots 24 of the frame body 21 to securely connect the
connector 30 with the frame body 21. The shielding device 20 of the
present invention can have a torque value over 60 kg-cm. The
shielding device 20 of the present invention meets the requirement
for high torque specification.
[0021] FIGS. 6 and 7 show a second embodiment of the present
invention, in which the same components are denoted by the same
reference numerals as in the first embodiment. The second
embodiment is different from the first embodiment in that a
different number of arcuate slots are formed on the sideboard of
the shielding device 40. Preferably, four arcuate slots 41 are
formed on the sideboard 22 of the shielding device 40 around the
receiving hole 23 at equal intervals. The connector 30 has four
arcuate protrusions 42 formed on the end face of the main body
section 31 corresponding to the arcuate slots 41. The four arcuate
protrusions 42 are assembled in the four arcuate slots 41 to
securely connect the connector 30 with the frame body 21. Also, the
shielding device 40 of the present invention can have a torque
value over 60 kg-cm.
[0022] In conclusion, the shielding device 20, 40 of the present
invention meets the requirement for high torque specification
without any additional reinforcing measure.
[0023] The above embodiments are only used to illustrate the
present invention, not intended to limit the scope thereof. It is
understood that many changes or modifications of the above
embodiments can be made by those who are skilled in this field
without departing from the spirit of the present invention. The
scope of the present invention is limited only by the appended
claims.
