Abstract

An electro mechanical or electrical connector for use in an electric vehicle including a plug body, a sealing ring, a locking member, and a cable is provided. The plug body has an inner wall and at least one locking recess on the inner wall. The sealing ring and the locking member are respectively disposed on the inner wall. The locking member has at least one elastic locking hook. The cable passes through the plug body, the sealing ring, and the locking member. The locking member is locked in the locking recess by the elastic locking hook to be attached to the inner wall, and forces the sealing ring to seal a space between the inner wall and the cable.

First claim

What is claimed is:

1 . An electro mechanical or electrical connector for use in an electric vehicle, the electro mechanical connector comprising:
a plug body having an inner wall and at least one locking recess on the inner wall; a sealing ring disposed on the inner wall; a locking member disposed on the inner wall, wherein the locking member has at least one elastic locking hook; and a cable passing through the plug body, the sealing ring, and the locking member, wherein the locking member is locked in the locking recess by the elastic locking hook to be attached to the inner wall, and forces the sealing ring to seal a space between the inner wall and the cable.

2 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 1 , wherein the sealing ring and the locking member are located at a tail end of the plug body, and the electro mechanical connector for use in the electric vehicle further comprises a plurality of metal contacts disposed at a head end of the plug body and electrically connected to the cable.

3 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 1 , wherein the inner wall has a stepped structure, the locking member that is locked on the inner wall applies force to the sealing ring, so that the sealing ring tightly abuts the stepped structure, and a direction of a force application is parallel to an extending axial direction of the cable.

4 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 3 , wherein the stepped structure comprises two annular walls with different inner diameters, and a step wall adjacent to the two annular walls, the locking member and the sealing ring are located on an annular wall with a greater inner diameter, and the locking member pushes an annular body of the sealing ring to tightly abut the step wall.

5 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 4 , wherein the sealing ring further has a plurality of annular protrusions on inner and outer surfaces, and the sealing ring is forced by the locking member to deform, so that the plurality of annular protrusions on the outer surface tightly abut the annular wall, and the plurality of annular protrusions on the inner surface tightly abut the cable.

6 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 5 , wherein the plurality of annular protrusions on the outer surface are intervally distributed in the extending axial direction of the cable, and the plurality of annular protrusions on the inner surface are intervally distributed in the extending axial direction of the cable.

7 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 1 , wherein the locking member further comprises:
a bottom ring; and a side ring extending from the bottom ring and tightly abutting the sealing ring, wherein an elastic arm of the elastic locking hook extends from the bottom ring to the side ring, and is suspended on the side ring, and a locking hook portion of the elastic locking hook is located at a free end of the elastic arm.

8 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 7 , wherein the bottom ring has a pair of necking recesses adjacent to two opposite sides of the elastic arm.

9 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 7 , wherein the plug body further has at least one releasing recess on the inner wall, a gap exists between the elastic arm and the releasing recess, the gap is tapered toward the locking recess, and a fixture is adapted for extending into the gap to press and deform the elastic arm, so that the locking hook portion is disengaged from the locking recess.

10 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 1 , wherein the locking member has a plurality of elastic locking hooks symmetrical relative to an extending axial direction of the cable.

11 . An electro mechanical or electrical connector for use in an electric vehicle, comprising:
a plug body having an inner wall, a tail end, and at least one locking recess on the inner wall; a cable passing through the plug body from the tail end; a first protection assembly sleeved on the cable and locked in the locking recess to seal a space between the inner wall and the cable; and a second protection assembly sleeved on the cable, assembled at the tail end of the plug body, and partially passing through the plug body to abut the first protection assembly, wherein the second protection assembly comprises: a bundle tube sleeved outside the cable and abutting the first protection assembly, wherein the bundle tube is elastic; an annular bundle claw extendably and retractably sleeved outside the bundle tube in a radial direction; and a back cover locked at the tail end and driving the annular bundle claw to contract, to enable the annular bundle claw to clamp the cable through the bundle tube.

12 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 11 , wherein the first protection assembly comprises:
a sealing ring disposed on the inner wall and sleeved on the cable; and a locking member sleeved on the cable and located at the tail end, wherein the locking member has at least one elastic locking hook, and the locking member is locked in the locking recess by the elastic locking hook to be attached to the inner wall, and forces the sealing ring.

13 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 12 , further comprising a plurality of metal contacts disposed in a head end of the plug body and electrically connected to the cable.

14 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 12 , wherein the inner wall has a stepped structure, the locking member that is locked on the inner wall applies force to the sealing ring, so that the sealing ring tightly abuts the stepped structure, and a direction of a force application is parallel to an extending axial direction of the cable.

15 . The electro mechanical or electrical connector for use in the electric vehicle according to claim 14 , wherein the stepped structure comprises two annular walls with different inner diameters and a step wall adjacent to the two annular walls, the locking member and the sealing ring are located on an annular wall with a greater inner diameter, and the locking member pushes an annular body of the sealing ring to tightly abut the step wall.
