DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

(8) FIG. 1 is an exploded sectional view in accordance with a first embodiment of the present invention. FIG. 2 is an assembled sectional view in accordance with the first embodiment of the present invention. The present invention discloses a connector assembly 100 applied to a high-voltage interface. In this embodiment, the connector assembly 100 is a combination of a bushing and an elbow arrester, but it may be a combination of other high-voltage interfaces. This embodiment does not limit the scope of the present invention. The connector assembly 100 applied to a high-voltage interface comprises a first connector 10 and a second connector 20.

(9) The first connector 10 is made of a resilient insulating material, such as rubber. One end of the first connector 10 is recessed along an axis X to form at least one accommodating groove 11. The bottom of the accommodating groove 11 is provided with a chamber 12. The other end of the first connector 10 is formed with a first through hole 13 communicating with the chamber 12. A socket 14 is provided in the chamber 12. The socket 14 has a fixing member 141. The fixing member 141 is made of a resilient insulating material and fixed in the chamber 12. A connecting member 142 is fixed to a middle portion of the fixing member 141. The connecting member 142 is made of a conductive material and has at least one electrical connection hole 15 therein corresponding to the accommodating groove 11. The electrical connection hole 15 is parallel to the axis X and communicates with the accommodating groove 11. In addition, an elastic holding portion 16 is provided around the electrical connection hole 15. The elastic holding portion 16 is composed of a plurality of elastic pieces 161 provided on the inner wall of the electrical connection hole 15. A first engaging portion 17 is provided at the socket 14. In this embodiment, the first engaging portion 17 is an engaging groove 171 around the outer side of the electrical connection hole 15. In addition, a first conductor 18 is provided in the first through hole 13. One end of the first conductor 18 is connected to the connecting member 142 of the socket 14, and the other end of the first conductor 18 forms a connecting end 181 for connecting an electrical device.

(10) The second connector 20 is made of a resilient insulating material, such as rubber. The second connector 20 has a plug-in portion 21 corresponding to the accommodating groove 11. The plug-in portion 21 has a second through hole 22 therein. A second conductor 23 is provided in the second through hole 22. One end of the second conductor 23 is formed with a screw hole 231 for screwing a conductive probe 24, and the other end of the second conductor 23 is formed with a connecting portion 232 for connecting an electrical device. The conductive probe 24 has a threaded portion 241 corresponding to the screw hole 231. The threaded portion 241 is screwed into the screw hole 231. The conductive probe 24 has a contact portion 242 extending out of the plug-in portion 21 and corresponding to the electrical connection hole 15. The contact portion 242 is parallel to the axis X. The conductive probe 24 further has a second engaging portion 25 corresponding to the first engaging portion 17. In this embodiment, the second engaging portion 25 is an engaging ring 251 fitted onto the contact portion 242. The contact portion 242 of the conductive probe 24 has an annular flange 243 corresponding to the plug-in portion 21. The threaded portion 241 of the conductive probe 24 is first inserted through the engaging ring 251 and then screwed into the screw hole 231 to hold the engaging ring 251 between the plug-in portion 21 and the annular flange 243.

(11) Referring to FIG. 1 and FIG. 2, because the accommodating groove 11 and the electrical connection hole 15 of the first connector 10, the plug-in portion 21 of the second connector 20 and the contact portion 242 of the conductive probe 24 are all parallel to the axis X, when the first connector 10 and the second connector 20 are to be connected, the plug-in portion 21 is aligned with and inserted into the accommodating groove 11 along the axis X, and the engaging ring 251 is engaged into the engaging groove 171, so that the plug-in portion 21 is secured in the accommodating groove 11 stably, and the contact portion 242 of the conductive probe 24 is inserted into the electrical connection hole 15 of the first connector 10, and the elastic pieces 161 of the elastic holding portion 16 elastically abut against the contact portion 242 to conduct the first conductor 18 and the second conductor 23. Furthermore, the electrical devices connected to the first connector 10 and the second connector 20 can be conducted to each other. When the first connector 10 and the second connector 20 are to be disengaged from each other, the user applies a force outwardly along the X axis to disengage the engaging ring 251 from the engaging groove 171, so that the first connector 10 and the second connector 20 can be separated easily. Thereby, the user can connect or disconnect the first connector 10 and the second connector 20 in a sliding manner.

(12) FIG. 3 is an exploded sectional view in accordance with a second embodiment of the present invention. FIG. 4 is an assembled sectional view in accordance with the second embodiment of the present invention. The connector assembly 100 applied to a high-voltage interface differs from the first embodiment in that the first engaging portion 17 has a groove 172 disposed around the inner wall of the electrical connection hole 15, an elastic retaining ring 173 is provided in the groove 172, and the second engaging portion 25 is an annular groove 252 disposed on the outer surface of the contact portion 242. Thus, when the plug-in portion 21 is aligned with and inserted into in accommodating groove 11 along the axis X and the contact portion 242 of the conductive probe 24 is inserted into the electrical connection hole 15, the elastic retaining ring 173 will be elastically snapped into the annular groove 252 to secure the plug-in portion 21 into the accommodating groove 11 stably.

(13) FIG. 5 is an exploded sectional view in accordance with a third embodiment of the present invention. FIG. 6 is an assembled sectional view in accordance with the third embodiment of the present invention. The connector assembly 100 applied to a high-voltage interface differs from the first embodiment in that the elastic holding portion 16 is composed of a plurality of elastic claws 162 extending outward from the electrical connection hole 15. Thus, when the plug-in portion 21 is aligned with and inserted into in accommodating groove 11 along the axis X and the contact portion 242 of the conductive probe 24 is inserted into the electrical connection hole 15, the elastic claws 162 will elastically hold the contact portion 242 of the conductive probe 24 to conduct the first conductor 18 and the second conductor 23.

(14) 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.
