[0025] The following only illustrates possible embodiments of the present application, but is not intended to limit the scope of the present application. The term "one" or "at least one" is not intended to limit the quantity. The quantity can be "multiple" according to the requirements. The change in the quantity is also intended to be protected. The foregoing is stated.

[0026] Please refer to Figures 1 to 7 which shows one embodiment of the present application. The waterproof connector of the present application includes a housing 1, an electrical connection assembly 2, and a waterproof assembly 4.

[0027] The housing 1 includes a first port 12, an internal space 11, and a second port 13. The first port 12 is used for inserting a connector of a device to be connected. The second port 13 is used for passing a cable 7 to extend into the internal space 11. The cable 7 includes at least one wire 71.

[0028] Further, the waterproof connector further includes a connecting piece 6. The housing 1 further includes a main body portion 14 and a pivot portion 15. The pivot portion 15 protrudes from the main body portion 14. The main body portion 14 and the pivot portion 15 jointly define the internal space 11. The main body portion 14 is provided with the second port 13. The pivot portion 15 is provided with the first port 12. The connecting piece 6 is rotatably sleeved on the pivot portion 15. The connecting piece 6 is used for connecting the device to be connected. Further, one of the connecting piece 6 and the pivot portion 15 is provided with a ring groove 16. The other one is provided with a clamping protrusion 61. The clamping protrusion 61 is movably embedded in the ring groove 16 along the ring groove 16. Thus, the connecting piece 6 can be freely rotated relative to the pivot portion 15.

[0029] The electric connection assembly 2 is accommodated in the internal space 11, and comprises a first seat 21, a second seat 24, and at least one conductive terminal 3. The first seat 21 is closer to the first port 12 than the second seat 24. The first seat 21 comprises at least one passage 22. The second seat 24 comprises at least one positioning portion 25 for accommodating the at least one wire 71. The at least one conductive terminal 3 comprises a conductive connecting portion 31 and a fork portion 32. The fork portion 32 of the at least one conductive terminal 3 is inserted into the at least one positioning portion 25 and is used for piercing the at least one wire 71 to form an electrically conductive relationship. The connecting portion 31 of the at least one conductive terminal 3 is arranged to pass through the at least one passage 22 to approach the first port 12, so as to be connected to a device to be connected.

[0030] Preferably, the first seat 21 and the second seat 24 are made of insulating materials to prevent electric leakage.

[0031] Preferably, the connecting portion 31 and the fork portion 32 are integrally formed, which can save assembly steps, has good structural continuity, and has excellent stability in use. In the embodiment, the fork portion 32 comprises a base portion 321 and two piercing members 322. The two piercing members 322 are spaced apart from each other and protrude from the base portion 321 to pierce the wire 71. The free ends of the two piercing members 322 jointly define a cavity 323 that gradually expands away from the base portion 321. The cavity 323 is used for accommodating a portion of the wire 71. Thus, the two piercing members 322 can firmly clamp the wire 71 to ensure that the connection state is not easily separated and falls off.

[0032] The waterproof assembly 4 is arranged in the shell 1, so that the internal space 11 cannot communicate with the outside through the second port 13. Thus, external liquid cannot enter the internal space 11 through the second port 13, and the waterproof connector can be used safely in an external or liquid environment. Users do not need to worry about electric leakage.

[0033] It is worth mentioning that the waterproof connector preferably further comprises a conductive grounding member 5. The grounding member 5 is accommodated in the internal space 11 and is electrically connected to a grounding wire 72 of the cable 7 to implement electrical connection specifications and ensure the safety of personnel and equipment. In the embodiment, the shell 1 is made of insulating material. The grounding member 5 and the shell 1 jointly clamp the grounding wire 72. This clamping method can stably clamp the grounding wire 72 without the need for additional clamping elements, which saves cost and eliminates complicated assembly procedures.

[0034] The first protrusion 26 is slidably inserted into the first slot 51, so that the grounding member 5 and the second seat body 24 can be quickly assembled with each other, thereby effectively saving the assembly time. Similarly, the second protrusion 27 is slidably inserted into the second slot 23, so that the first seat body 21 and the second seat body 24 can be assembled with each other.

[0035] As can be seen from the above, the second seat body 24 is clamped between the first seat body 21 and the grounding member 5, and the first seat body 21, the second seat body 24 and the grounding member 5 are combined into a component, so that the first seat body 21, the second seat body 24 and the grounding member 5 can have more contact area with the shell 1 in the internal space 11, and the first seat body 21, the second seat body 24 and the grounding member 5 cannot be shaken relative to the shell 1 at will, thereby helping to maintain the assembly stability between elements.

[0036] The waterproof assembly 4 further includes a covering body 41, a claw sleeve 42, a waterproof member 43 and a control member 44. The covering body 41 is located in the internal space 11 and is provided for the cable 7 to pass through. The claw sleeve 42 is made of elastic material. The claw sleeve 42 is sleeved on the covering body 41 and includes a plurality of claw portions 421 and a center line 422. The control member 44 is movably arranged on the shell 1. The control member 44, the shell 1 and the claw sleeve 42 jointly define a containing space 45. The containing space 45 is located on the outer circumferential side of the claw sleeve 42. The waterproof member 43 is contained in the containing space 45. The control member 44 is operated by the outside to drive the waterproof member 43 to press against the plurality of claw portions 421 to shrink in the direction of the center line 422, so that the plurality of claw portions 421 push against the covering body 41 to tighten the cable 7, thereby eliminating the gap between the covering body 41 and the cable 7, and effectively blocking the water flowing along the cable 7 from the outside.

[0037] In the embodiment, the waterproof member 43 is annularly sleeved on the plurality of claw portions 421. The waterproof member 43 is made of deformable material, for example but not limited to rubber. The waterproof member 43 is located between the shell 1 and the control member 44. When the control member 44 is close to the shell 1 to clamp the waterproof member 43, the waterproof member 43 is deformed by force to push the plurality of claw portions 421 to move in the direction of the center line 422.

[0038] The above describes the preferred embodiment of the utility model and the technical principle used thereby. For those skilled in the art, any equivalent transformation, simple replacement and the like based on the technical scheme of the utility model without departing from the spirit and scope of the utility model shall belong to the protection scope of the utility model.
