[0046] In some embodiments, the elastic pin 22 comprises a needle head 221, a needle barrel 222, and a second spring 223; the needle barrel 222 comprises a first needle barrel part 222a and a second needle barrel part 222b, at least the second needle barrel part 222b is installed in the clamping groove of the hole insulator 21, the diameter of the second needle barrel part 222b is smaller than that of the first needle barrel part 222a; the second spring 223 is installed in the first needle barrel part 222a, one end of the second spring 223 abuts against the second needle barrel part 222b; one end of the needle head 221 is installed in the first needle barrel part 222a and abuts against the other end of the second spring 223, the other end of the needle head 221 protrudes from the other end of the second needle barrel part 222b away from the first needle barrel part 222a.

[0047] For example, the first needle barrel part 222a comprises a hollow cavity, the second spring 223 is installed in the hollow cavity of the first needle barrel part 222a, and one end of the needle head 221 is installed in the hollow cavity of the first needle barrel part 222a and abuts against the other end of the second spring 223 in the hollow cavity of the first needle barrel part 222a.

[0053] In some embodiments, as shown in Figure 7 The inner wall of the cavity of the socket shell 10 is provided with an axially extending vertical groove 101, and the outer surface of the hole insulator 21 is provided with a protruding key 201 matched with the vertical groove 101.

[0054] For example, the inner side of the socket shell 10 is axially provided with a vertical groove 101, and the outer surface of the hole insulator 21 is provided with a protruding key 201 matched with the vertical groove 101. The axially vertical groove 101 of the inner side of the socket shell 10 is matched with the surface protruding key 201 of the hole insulator 21, and the outer side of the maximum end of the hole insulator 21 is matched with the inner wall of the socket shell 10. Through this structure, the needle assembly (a plurality of elastic pins 22) of the hole insulator 21 is effectively unified and limited (aligned) with the identification point of the socket shell 10.

[0055] In some embodiments, the socket shell 10 comprises an internal thread; the outer diameter of the first end of the middle nut 30 is smaller than the outer diameter of the second end, the middle nut 30 comprises an external thread at the first end, the middle nut 30 comprises an internal thread at the second end, and the external thread of the first end of the middle nut 30 is connected with the internal thread of the socket shell 10; the screw rod part of the tail nut 60 comprises an external thread, and the external thread of the screw rod part of the tail nut 60 is connected with the internal thread of the second end of the middle nut 30.

[0056] For example, one end of the middle nut 30 close to the socket shell 10 is the first end, and the other end of the middle nut 30 away from the socket shell 10 is the second end.

[0057] For example, in some embodiments, the rear inner side of the socket shell 10 is provided with a shell groove for accommodating the middle nut 30, the front end of the socket shell 10 has a step-like structure protruding inward, the needle end of the elastic pin 22 on the hole insulator 21 faces forward, the side protruding key 201 of the hole insulator 21 is aligned with the vertical groove 101 on the inner side of the socket shell 10, and the hole insulator 21 is inserted along the axial direction from the tail of the socket shell 10.

[0059] For example, Figure 1 The head 61 of the tail cap and the screw portion 62 of the tail cap are shown in

[0060] For example, the first spring 50 can protect the cable or plug connected to the socket 100, resist vibration impact, and improve the reliability of the cable and other components connected to the connector.

[0061] In some embodiments, the socket 100 of the connector further comprises a gasket 70 arranged between the sealing gasket 40 and the first spring portion 501; the sealing gasket 40 comprises a second hollow hole, and the second hollow hole communicates the space on the side away from the socket housing 10 and the side close to the socket housing 10 of the sealing gasket 40.

[0062] For example, the gasket 70 can buffer the force between the first spring 50 and the sealing gasket 40, thereby improving the reliability of the socket.

[0063] In some embodiments, the socket 100 of the connector comprises a socket cavity, the socket cavity passes through the first spring 50, the tail cap 60, the sealing gasket 40, the middle cap 30 and part of the socket housing 10 in sequence, and the socket cavity exposes the elastic pins 22.

[0064] For example, the socket cavity passes through the first spring 50, the tail cap 60, the sealing gasket 40, the middle cap 30 and part of the positioning ring 23 in sequence, so that the socket cavity exposes the elastic pins 22 in the positioning ring 23, as shown in Figure 4 The elastic pins 22 can be seen through the socket cavity in the side view of the first spring 50 on the side away from the socket housing 10, so that the needle 221 can be inserted into the socket cavity when the plug is connected to the socket 100, thereby realizing the electrical connection between the plug and the socket 100.

[0065] For example, Figure 5 The end of the socket housing 10 can be seen in the side view of the socket housing 10 on the side away from the tail cap 60, as shown in Figure 5

[0066] ​For example, in some embodiments, the front O-shaped sealing ring 81 is inlaid and fixed in the groove behind the front end protruding step structure inside the socket shell 10, and the rear O-shaped sealing ring 82 is inlaid and fixed in the front end groove of the rear threaded portion of the socket shell 10.

[0067] For example, the inner wall of the socket shell 10 includes a front end away from the middle nut 30, a rear end connected with the middle nut 30, and a middle end between the front end and the rear end. The inner diameter of the front end of the socket shell 10 is smaller than the inner diameter of the middle end, and the inner diameter of the middle end is smaller than the inner diameter of the rear end. The front end and the middle end of the socket shell 10 accommodate and fix the positioning ring 23, the positioning ring 23 fixes the hole insulator 21, the plurality of elastic pins 22 are fixed on the clamping groove of the hole insulator 21 and protrude from the hole insulator 21 towards the middle nut 30 in the middle end. The rear end includes an internal thread, and the internal thread of the rear end is connected with the external thread of the middle nut 30.

[0068] For example, the front O-shaped sealing ring 81 is inlaid and fixed in the groove of the front end, and the rear O-shaped sealing ring 82 is inlaid and fixed in the groove of the rear end, so that the socket has good waterproof function.

[0069] For example, in some embodiments, the outer surface of the socket shell 10 is provided with a wave-shaped protrusion for facilitating hand holding and force exertion. In addition, in order to facilitate locking the shell, a flat position for wrench clamping is arranged in the middle of the wave structure.

[0070] For example, in some embodiments, the socket 100 further includes a tail nut 60. The inner cavity of the tail nut 60 is funnel-shaped with a large front end and a small rear end. The first spring 50 is axially sleeved into the tail nut 60 from the front end. The inner surface of the tail end of the tail nut 60 is provided with a circular chamfer, and the outer surface is provided with a regular hexagonal protruding structure. The middle nut 30 is inversely funnel-shaped with a large rear end and a small front end. The rear end is provided with a threaded groove for accommodating the tail nut 60. The small end of the sealing gasket 40 is axially pushed into the middle nut 30, and then the gasket 70 is placed on the sealing gasket 40. The tail nut 60 with the first spring 50 is axially abutted against the gasket 70, and is screwed into the middle nut 30 for locking and fixing.

[0071] For example, in some embodiments, the outer side wall of the head of the socket 100 is axially provided with an L-shaped clamping key groove for mating with the male end. In some embodiments, the outer surface of the shell of the socket 100 is provided with a flat position for direction identification and an identification point.

[0072] For example, in some embodiments of the present application, the front end sealing ring of the plug in contact with the front end sealing ring of the plug during mating is extruded by the front protrusion on the socket 100 shell, forming an outer waterproof shell, and the overall structure is compact, the appearance is simple, and the socket is suitable for use in small space and has wide application range.

[0073] For example, in some embodiments of the application, the waterproof effect between the shell of the socket 100 and the middle nut 30 and between the middle nut 30 and the tail nut 60 is increased by installing the rear O-shaped sealing ring 82 and the sealing gasket 40, so as to effectively achieve the waterproof function without increasing other structures, and meet the requirement of compact product structure.

[0074] For example, in some embodiments of the application, the direction of the elastic pin 22 is accurately ensured by the cooperation between the protruding key 201 of the hole insulator 21 and the axial vertical bar groove 101 on the inner surface of the socket shell 10, the circumferential array of the hole insulator 21 is provided with a clamping groove for clamping the pin, which can ensure the mutual isolation between the elastic pins 22, increase the creepage distance, and have higher withstand voltage; the inner side of the tail nut 60 shell tail is chamfered, which can effectively increase the rotating range of the first spring 50 to the periphery, increase the bending and pulling-off strength after the cable is assembled, and have higher reliability.

[0075] For example, in some embodiments of the application, the existing metal buckle connector cannot be used in a narrow space due to its poor use environment, and the connector has superior environmental performance, strong waterproof and anti-vibration impact performance, and the technical scheme of the application is convenient to realize pure electricity and pure signal functions, and has good operation, light weight, and high reliability.

[0076] The application also provides a connector, which comprises the socket 100 according to any one of the above embodiments, and a plug which can be connected to the socket 100.

[0077] The technical features of the above embodiments can be combined arbitrarily, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0078] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
