For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0024] See also Figures 1 to 4 A connector with a sealing structure according to an embodiment of the utility model is characterized in that it includes a plug shell 1, wherein the outer end surface of the plug shell 1 is provided with a group of claws 11 and a slot 12; a retaining ring 2, wherein the inner end surface of the retaining ring 2 is provided with a protruding block 21 engaged with the slot 12, the retaining ring 2 is sleeved on one end of the plug shell 1, and a spring 22 is sleeved on the outer side of the retaining ring 2; a pin insulator 3, wherein the pin insulator 3 is provided with an engaging groove 31 engaged with the claw 11, and the pin insulator 3 is clamped on the inner side of the retaining ring 2; and a connecting nut 4, wherein the connecting nut 4 is sleeved on the plug shell 1 and threadedly connected to the plug shell 1.

[0025] In the above embodiment, the outer end surface of the plug housing 1 is designed with a group of claws 11 and slots 12 for locking and fixing with other components. The inner end surface of the retaining ring 2 is provided with a protruding block 21 engaged with the slot 12 to ensure the tight connection between the retaining ring 2 and the plug housing 1. The outer side of the retaining ring 2 is sleeved with a spring 22 to provide elastic force during connection and separation. The pin insulator 3 is provided with an engaging groove 31 engaged with the claw 11 to play the role of insulation and fixing. Finally, the connecting nut 4 is sleeved on the plug housing 1 and fastened by threaded connection. During the connection process, when the connecting nut 4 is tightened, it pushes the retaining ring 2 and the pin insulator 3 to move inward along the plug housing 1. Since the protruding block 21 on the inner side of the retaining ring 2 is engaged with the slot 12 of the plug housing 1, a stable connection is formed between the retaining ring 2 and the plug housing 1. At the same time, the engaging groove 31 of the pin insulator 3 is engaged with the claw 11 of the plug housing 1 to ensure the stability of the position of the pin insulator 3. At this time, the spring 22 is compressed to provide elastic force for the subsequent separation process. During the separation process, when the connecting nut 4 is loosened, the elastic force of the spring 22 will push the retaining ring 2 and the pin insulator 3 to move outward, separating them from the plug housing 1. Due to the interlocking design of the claw 11 and the interlocking groove 31, and the interlocking design of the protruding block 21 and the slot 12, the stability and reliability of each component during the separation process are guaranteed. The working principle of this push-pull self-locking connector is simple and efficient. It achieves quick connection and separation through threaded connection and the elastic force of the spring 22, and at the same time uses the claw 11, the slot 12 and the interlocking groove 31 to ensure the stability and reliability of the connection. In addition, the high-density miniaturized design makes the connector suitable for occasions with small space and high connection density requirements.

[0026] Please refer to Figures 1 to 4 In another embodiment, a friction layer is provided on the outer side of the connecting nut 4.

[0027] In the above embodiment, the friction between the connecting nut 4 and the user's hand or other tools is increased, so that the user can operate more stably and easily when rotating the connecting nut 4.

[0028] Please refer to Figures 1 to 4 In another embodiment, the claws 11 are arranged in a ring shape along the outer end surface of the plug housing 1 .

[0029] In the above embodiment, the annular claw 11 can provide uniform force distribution. No matter which direction the external force is applied, the claw 11 can effectively bear and disperse the force, thereby ensuring the stability and reliability of the connector. Secondly, the design of the annular claw 11 also increases the contact area between the connector and other components. This not only improves the firmness of the connection, but also helps to reduce the looseness or slippage that may occur during the connection process.

[0030] Please refer to Figures 1 to 4In another embodiment, the pin insulator 3 is provided with a plurality of plug holes 5 , and the plug pins 6 are arranged in the plug holes 5 .

[0031] In the above embodiment, the arrangement of the jack 5 enables the pin insulator 3 to accommodate multiple pins 6, thereby realizing multi-channel electrical connection. Each jack 5 can independently accommodate a pin 6, so the number of inserted pins 6 can be selected according to actual needs, meeting the needs of different application scenarios.

[0032] Please refer to Figures 1 to 4 In another embodiment, a sealing ring 9 is provided on the outer side of the needle insulator 3 .

[0033] In the above embodiments, the sealing performance of the connector is enhanced to ensure the safety and stability of the electrical connection.

[0034] Please refer to Figures 1 to 4 In another embodiment, it further includes a card shell 7 and a tail cap 8, wherein the card shell 7 is card-connected to the other end of the plug housing 1, and the tail cap 8 is sleeved on the card shell 7.

[0035] In the above embodiment, the card shell 7 fixes and supports the other end of the plug housing 1, thereby improving the structural strength of the entire connector. The card connection structure between the card shell 7 and the plug housing 1 makes them tightly combined and not easy to loosen or fall off, which helps to ensure the stability of the connector during use. Secondly, the tail cap 8 provides additional protection for the connector. The tail cap 8 is sleeved on the card shell 7, which can effectively prevent external impurities from entering the interior of the connector, further enhancing the sealing performance of the connector.

[0036] Please refer to Figures 1 to 4 In another embodiment, a sealing ring 9 is sleeved on the outer side of the casing 7.

[0037] In the above embodiment, the sealing ring 9 is tightly fitted on the outside of the card shell 7 to prevent moisture, dust or other impurities from entering the interior of the connector. In particular, in some harsh working environments, such as places with high humidity, dust or corrosive gases, the presence of the sealing ring 9 is particularly critical. It can effectively prevent these adverse factors from corroding the interior of the connector, thereby maintaining the electrical performance and stability of the connector.
