CABLE CONNECTOR

Abstract

A cable connector includes a soft body. The soft body has at least one connecting portion. An outer wall surface of the connecting portion is provided with a hard casing. The soft body is made of a soft material, such as rubber and silicone rubber. The hard casing is made of a hard material, such as plastic, and has higher rigidity than the soft body. When a bushing of a cable is inserted into the connecting groove of the connecting portion, the hard casing is configured to resist deformation, so that the connecting portion will not be deformed by insertion of the bushing, thereby improving the electrical connection between the cable connector and the bushing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0014] FIG. 1 is a perspective view in accordance with a first embodiment of the present invention. FIG. 2 is a partial cross-sectional view in accordance with the first embodiment of the present invention. The present invention discloses a cable connector 100A in the form of a multi-point junction, comprising a soft body 10, a base cashing 20, and a plurality of hard casings 30.

[0015] The soft body 10 is made of a soft material including rubber or silicone rubber, such as EPDM. The soft body 10 has a base 11. A conductive portion 111 is embedded in the base 11. The outside of the base 11 is provided with a plurality of raised connecting portions 12 each serving as a female interface. An end portion of each connecting portion 12 is concavely formed with a generally conical connecting groove 121. A connecting terminal 122 is provided at the bottom of the connecting groove 121. The connecting terminal 122 is connected to the conductive portion 111.

[0016] The base casing 20 is disposed on the outside of the base 11. The base casing 20 has perforations 21 corresponding to the respective connecting portions 12, so that the corresponding connecting portions 12 are inserted in the perforations 21, respectively. Wherein, the base casing 20 is provided with a raised annular portion 22 on the periphery of each perforation 21. The raised annular portion 22 is arranged around each connecting portion 12. The height of the raised annular portion 22 is less than the height of the connecting portion 12.

[0017] The plurality of hard casings 30 are made of a hard material including plastic, such as polyacetylene (PAC), and have higher rigidity than the soft body 10. Each hard casing 30 is disposed around the outer wall surface of each connecting portion 12 and is located at a position corresponding to the connecting groove 121. Each hard casing 30 extends downward to cover the outside of the raised annular portion 22.

[0018] FIG. 3 is a schematic view in accordance with the first embodiment of the present invention when in use. The cable connector 100A is in cooperation with a bushing 200 of a cable when in use. The bushing 200 is inserted into the connecting portion 12 through the connecting groove 121, and a connecting terminal 201 of the busing 200 is threadedly connected to the connecting terminal 122 of the connecting portion 12. Because the hard casing 30 is provided on the outer wall surface of the connecting portion 12, and the hard casing 30 is made of a plastic material having higher rigidity than the soft body 10, when the bushing 200 is inserted in the connecting groove 121, the hard casing 30 is configured to resist radial deformation, so that the connecting portion 12 will not be deformed by insertion of the bushing 200. Therefore, the connection between the connecting portion 12 and the bushing 200 is tighter and firmer to ensure that no looseness or clearance occurs when pulled by an external force, thereby improving the electrical connection between the cable connector 100A and the bushing 200.

[0019] FIG. 4 is a partial cross-sectional view in accordance with a second embodiment of the present invention. The second embodiment is substantially similar to the first embodiment with the exceptions described hereinafter. Because the soft body 10 and the hard casing 30 are made of different materials, in order to prevent the hard casing 30 from falling off, the cable connector 100A is provided with an adhesive layer 40, such as a bridging agent, between the connecting portion 12 and the hard casing 30, thereby improving the joint strength of the hard casing 30 fixed to the outer wall surface of the connecting portion 12.

[0020] FIG. 5 is a partial cross-sectional view in accordance with a third embodiment of the present invention. Except that the present invention is applied to the cable connector 100A in the form of a multi-joint junction shown in the first and second embodiments, those skilled in the art can understand that the present invention can also be applied to other types of cable connectors, for example, a cable connector 100B in the form of a reducing tap well shown in this embodiment. The cable connector 100B has the soft body 10. One end of the soft body 10 is provided with the connecting portion 12. The connecting portion 12 is concavely formed with the connecting groove 121. The bottom of the connecting groove 121 is provided with the connecting terminal 122. The outer wall surface of the connecting portion 12 is provided with the hard casing 30. Thereby, the hard casing 30 also provides an anti-deformation effect to improve the electrical connection.

[0021] FIG. 6 is a partial cross-sectional view in accordance with a fourth embodiment of the present invention. This embodiment discloses a cable connector 100C in the form of an elbow. The cable connector 100C has the soft body 10. The soft body 10 is in an L-shape. One end of the soft body 10 is provided with the connecting portion 12. The connecting portion 12 is concavely formed with the connecting groove 121. The bottom of the connecting groove 121 is provided with the connecting terminal 122. The outer wall surface of the connecting portion 12 is provided with the hard casing 30. Thereby, the hard casing 30 also provides an anti-deformation effect to improve the electrical connection.

[0022] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
