Detailed Description

The following describes the embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 3, one connector is divided into two parts of a positive connector and a negative connector.

Referring to fig. 4 to 6, taking the positive connector as an example, the components of the present invention include: the connector 101, a pin 102, a retaining ring 103, a sealing element 104, a wire fixing element 105, a nut 106, a cable 107 and an O-ring 108. The utility model discloses an assembly structure as follows: the contact pin 102 and the retaining ring 103 are assembled, the contact pin 102 and the retaining ring 103 can also be integrally formed in a punching mode and then are embedded into the connector 101; alternatively, the retainer ring 103 is first installed into the connector 101 and then the pin 102 is inserted. The pin 102 is a metal piece and the anti-backup ring 103 may be a non-conductive member. The function of the retaining ring 103 is that the elastic part of the retaining ring 103 contacts with the inside of the connector 101 to form an inverse buckle, so as to realize the positioning of the pin 102. The pin 102 has a conductive function, and one end of the pin is responsible for being inserted into a pin of the other polarity, and the other end of the pin is responsible for being connected with a cable. The O-ring 108 is fitted over the mating end of the connector 101 and the connector of the other polarity, and the O-ring 108 functions to seal when the connector 101 and the connector of the other polarity are mated. The cable 107 is riveted to the cable insertion end of the pin 102.

One end of an inner hole of the sealing element 104 is a large hole, the other end of the inner hole is a small hole, the wire fixing element 105 is placed in the large hole end of the sealing element 104, the sealing element 104 and the wire fixing element 105 are placed in the connector 101 of the connector together, the end portion of the connector 101 is connected with the nut 106 through threads, the nut 106 is firstly screwed for a plurality of circles, then the cable 107 is inserted into the connector, and the cable 107 sequentially penetrates through the nut 106, the wire fixing element 10 and the small hole of the sealing element 104 to be riveted on the inserting pin 102. And continuously screwing the nut 106, wherein in the process of screwing the nut 106, the sealing element 104 deforms under the extrusion force of the nut 106, the inner hole of the sealing element 104 is reduced, the wire fixing element 105 is extruded, and the wire fixing element 105 is extruded and then fastened with the cable 107, so that the wire fixing function is realized, and dust and moisture are prevented from entering the connector.
