[0024] refer to Figure 1-3 As shown, an embodiment of the present utility model is:

[0025] A photoelectric connector comprises a plug 1 and a socket 2, wherein the plug 1 and the socket 2 are provided with a connector 3 that is plugged into and fits with each other, the outer ends of the plug 1 and the socket 2 are both threadedly connected with a waterproof sleeve 4, the inner wall of the waterproof sleeve 4 is provided with a sealing step 5, a seal is provided between the sealing step 5 and the connector 3, the seal comprises a wire sheath 6, a sealing sleeve 7 is provided inside the wire sheath 6, one end of the sealing sleeve 7 is provided with a first sealing gasket 8 that is adapted to the wire sheath 6 and the connector 3, the other end of the sealing sleeve 7 is provided with a second sealing gasket 9 that is adapted to the sealing step 5, and a compression washer 10 is provided between the second sealing gasket 9 and the wire sheath 6.

[0026] The first sealing gasket 8, the sealing sleeve 7 and the second sealing gasket 9 are made of rubber material and are integrally formed.

[0027] The wire protection sleeve 6 includes a pressing sleeve 61, which is provided with axial pressing claws 62. The axial pressing claws 62 are evenly spaced along the circumferential direction. A protrusion 63 is provided on the outer side of the end of the axial pressing claw 62. The compression washer 10 is provided with an annular pressing inclined surface 101 that adapts to the protrusion 63. The annular pressing inclined surface 101 is coaxially arranged with the compression washer 10, and the inner diameter of the annular pressing inclined surface 101 is consistent with the inner diameter of the compression washer 10.

[0028] An insulating sleeve 11 is provided on the outside of the connector 3 , and a stopper 12 adapted to the insulating sleeve 11 is provided inside both the plug 1 and the socket 2 . The end of the insulating sleeve 11 contacts the first sealing gasket 8 .

[0029] like Figure 2 As shown, the connector 3 in the plug 1 is a male plug, and the connector 3 in the socket 2 is a female socket. The front end of the male plug has a core, and the front end of the female socket corresponds to a jack with a core. Both the male plug and the female socket are clamped with an insulating sleeve 11; the stop step 12 in the plug 1 is set close to one side of the socket 2, and is used to limit the movement of the male plug toward the female socket, so that it can directly abut against the front end of the insulating sleeve 11; the stop step 12 in the socket 2 is used to limit the backward movement of the female socket in the initial installation stage to ensure that the male plug and the female socket are tightly connected, and because the rear end of its insulating sleeve 11 needs to contact the first sealing gasket 8, a retaining ring 13 is set in the middle to match the stop step 12.

[0030] There are two possible water seepage points at the cable connection: one is the threaded portion between the waterproof sleeve 4 and the main body, and the other is the rear end of the waterproof sleeve 4 along the cable entry direction. In actual use, the shaking of the cable can easily cause gaps at the entry position, making it easier for rainwater to penetrate. Therefore, the present application uses a sealing sleeve 7 in conjunction with the structure of the first sealing gasket 8 and the second sealing gasket 9. After the waterproof sleeve 4 is connected to the main body, the first sealing gasket 8 and the second sealing gasket 9 form an end face seal, and the annular pressing bevel 101 on the compression washer 10 squeezes the protrusion 63 in an eccentric direction, thereby forming an extrusion point in the middle of the sealing sleeve 7 in the center direction, so that the extrusion position in the middle of the sealing sleeve 7 to the second sealing gasket 9 is more tightly wrapped around the cable, and the sealing performance is better.

[0031] During specific implementation, in order to ensure that the annular pressing slope 101 contacts only the protrusion and to ensure that the protrusion 63 is squeezed toward the center (the connection point between the plug 1 and the socket 2), the inner diameter of the compression washer 10 is larger than the inner diameter of the compression sleeve 61, and the inner diameter of the compression washer 10 is smaller than the outer diameter of the ring formed by multiple protrusions 63.

[0032] The plug 1 is provided with a connecting nut 14 adapted to the socket 2 , the socket 2 is provided with a retaining ring 15 adapted to the connecting nut 14 , and the contact surface between the plug 1 and the socket 2 is provided with a sealing ring 16 .

[0033] When in use, the connecting nut 14 is pre-installed on the plug 1, and the cable corresponding to the plug end passes through the waterproof sleeve 4 and the seal and is connected to the plug connector 3, and then the plug connector 3 is inserted into the corresponding insulating sleeve 11, and the whole is inserted into the plug, and the waterproof sleeve 4 and the plug 1 are threadedly locked so that the front end of the insulating sleeve 11 contacts the stop step 12; the cable corresponding to the socket end passes through the waterproof sleeve 4, the seal and the socket 2 in turn and is connected to the plug connector 3, and then the plug connector 3 is inserted into the corresponding insulating sleeve 11, and then the whole is inserted into the socket 2, and the waterproof sleeve 4 is threadedly connected to the socket 2; then the front end of the plug 1 is inserted into the socket 2, and the connecting nut 14 is locked. At this time, the waterproof sleeve 4 on the socket 2 can be rotated again to ensure the connection strength.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
