[0022] The application will be further described below in conjunction with the drawings and specific embodiments. In the description of the application, it should be noted that the meaning of "a plurality of" is two or more, unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.
[0023] The present embodiment provides a specific embodiment of a connector:
[0024] Referring to FIGS. 1 to Figure 3 .
[0025] The connector of the present embodiment includes a socket body and a plug body, which can be any conventional arrangement in existing connectors, for example, as shown in Figure 1 For example, as shown in FIG. 1, the plug body is composed of a plug shell 16, a plug insulator 15 arranged in the plug shell 16, an inner shielding ring 4 and an outer shielding ring 5 arranged in the plug shell 16, a sealing wire body 2 arranged at the tail end of the plug shell 16, and a tail cover 1, a baffle 3 is arranged between the sealing wire body 2 and the inner shielding ring 4, an interface rubber ring 14 is arranged around the plug shell 16 for insertion with the socket body, and the socket body includes a socket shell 10.
[0026] The plug end contact 6 is arranged in the plug shell 16, and the socket end contact 12 is arranged in the socket shell 10. The plug end contact 6 and the socket end contact 12 correspond to the functions of the pins and the sockets in the existing connector, and the two are matched to realize the conduction of the connector. Different from the plug-in and plug-out matching of the pins and the sockets in the existing connector, in the embodiment, the plug end contact 6 and the socket end contact 12 can be abutted and matched to realize the conduction during the insertion of the socket body and the plug body. That is, during the insertion of the socket body and the plug body, the plug end contact 6 and the socket end contact 12 can be close to each other to realize close abutment. In order to ensure close abutment, the elastic member 11 is arranged in the connector to provide elastic force along the abutment direction of the plug end contact 6 and the socket end contact 12. After the plug end contact 6 and the socket end contact 12 are abutted, the elastic member 11 can press the socket end contact 12 and the plug end contact 6 along the abutment matching direction of the plug end contact 6 and the socket end contact 12 to realize close abutment of the socket end contact 12 and the plug end contact 6. Compared with the existing connector, there is no plug-in and plug-out of the contact, so there is no problem such as wear, deformation and easy deflection of the contact after multiple plug-in and plug-out. The physical positions of the plug body and the socket body can be changed within a small range allowed, the accuracy requirement of the position of the connector is lower than that of the traditional connector, the processing difficulty of the parts is greatly reduced, the qualified rate of the parts is improved, and the production cost is reduced.
[0027] In the embodiment, the elastic member 11 is made of a common elastic material such as a spring. The elastic member 11 can also be made of rubber or other materials that can provide elastic force.
[0028] It should be noted that, for the plug end contact 6 and the socket end contact 12, no matter how the plug end contact 6 is arranged on the plug body and no matter how the socket end contact 12 is arranged on the socket body, the elastic member 11 can be arranged in the plug body or the socket body during implementation, as long as the plug end contact 6 and the socket end contact 12 can be abutted and matched, and the elastic member 11 can provide mutual pressing force in the abutment direction after abutment.
[0029] In the embodiment, the elastic member 11 is arranged in the socket body, so that the plug end contact 6 and the socket end contact 12 can be abutted and matched during the insertion of the plug body and the socket body. Figure 1 As shown in the figure, the socket end contact 12 is arranged in the socket shell 10. The socket shell 10 is provided with a socket pressing plate 9 at the end for insertion. During use, the socket pressing plate 9 and the socket shell 10 are inserted into the insertion cavity of the plug shell 16. The socket pressing plate 9 is provided with an opening through which the socket end contact 12 can slide freely. The socket end contact 12 extends out of the socket pressing plate 9 through the opening, and the extended part forms an abutment end for abutment and matching with the plug end contact 6.
[0030] The elastic member 11 is sleeved on the socket end contact 12, one end of the elastic member 11 is connected to the socket end contact 12, and the other end is connected to the socket shell 10 of the socket body. The connection referred to here can be fixed connection or abutment. After the elastic member 11 is arranged, an initial pre-tightening force can be applied to the elastic member 11 during use, so that the initial pre-tightening force of the elastic member 11 supports the socket end contact 12, preventing the socket end contact 12 from freely falling into the socket pressure plate 9 and keeping the end of the socket end contact 12 extended.
[0031] In combination Figure 1 In this embodiment, the socket pressure plate 9 is arranged at the front end of the socket shell 10 for insertion. The area for placing the elastic member 11 is surrounded by the inner wall and the tail end of the socket shell 10 below the socket pressure plate 9. After the elastic member 11 is sleeved on the socket end contact 12, it can be placed in the area. As mentioned earlier, in order to further facilitate the initial pre-tightening force of the elastic member 11 to support the socket end contact 12, in combination Figure 3 As shown in the figure, the socket end contact 12 can be arranged in a rod shape, and the rod-shaped socket end contact 12 can also be provided with a boss. For example, the diameter of the socket end contact 12 at the position in the socket pressure plate 9 is greater than the diameter at the position in the area. The change in diameter forms the boss. The elastic member 11 is sleeved on the smaller diameter section. One end of the elastic member 11 abuts against the socket pressure plate 9 and the boss, and the other end abuts against the tail end of the socket shell 10. Understandably, a gasket 13 can be arranged between the elastic member 11 and the socket pressure plate 9, and between the elastic member 11 and the socket shell 10, to ensure stable elastic action between the two ends of the elastic member 11 and the contact surface.
[0032] In combination Figure 1 As shown in the figure, the plug body and the socket body are arranged in insertion. An open cavity can be arranged in the plug body, which is used for insertion and cooperation with the socket body. When the plug end contact 6 is arranged, a part of the plug end contact 6 is arranged in the cavity in a direction perpendicular to the insertion of the socket body and the socket body. The remaining part of the plug end contact 6 can be arranged on the plug insulator 15. During the insertion of the plug body and the socket body, since the plug end contact 6 is arranged in the cavity in a direction perpendicular to the insertion of the socket body and the socket body, it can better facilitate the abutment of the socket end contact 12 and the plug end contact 6. As mentioned earlier, the socket end contact 12 can be in a rod shape. In order to better abut the rod-shaped socket end contact 12, the plug end contact 6 is arranged in a sheet shape, i.e., the plug end contact 6 forms a planar shape in the cavity in a direction perpendicular to the insertion and abutment of the plug end contact 6.
[0033] In combination Figure 1 , Figure 2As shown, the plug end contact 6 is Z-shaped. The part of it inside the cavity is blocked in the contact direction by the front pressure plate 8 set on the socket body. When the connector is inserted, the contact plane of the plug end contact 6 first contacts the front end face of the socket end contact 12. As the plug body and the socket body are further inserted, the plug end contact 6 squeezes the socket end contact 12. The socket end contact 12 squeezes the gasket 13 and the elastic member 11 in sequence, so that the elastic member 11 is compressed and generates elastic force to squeeze the socket end contact 12 and the plug end contact 6 in the opposite direction, providing sufficient positive pressure for the plug end contact 6 and the socket end contact 12 to ensure effective and tight contact between the plug end contact 6 and the socket end contact 12.
[0034] In this embodiment, when setting the plug end contact 6, a positioning spring 7 is provided on the front pressure plate 8. The positioning spring 7 is used to restrict the movement of the plug end contact 6 in a direction perpendicular to the insertion of the socket body and the socket body, thereby ensuring the stability of the plug end contact 6 in the cavity and avoiding misalignment of the contact plane of the plug end contact 6, which would affect the effective tight contact between the plug end contact 6 and the socket end contact 12.
[0035] Combination Figure 1 , Figure 2 As shown in the figure, in this embodiment, a slot 601 is provided on the plug end contact 6. The slot 601 can be provided near the end of the plug end contact 6 used for abutment and engagement. Taking the example shown in the figure, the slot 601 can be provided on the panel opposite to the side of the plug end contact 6 used for abutment. When the positioning spring is performing the limiting function, a claw 701 that can extend into the slot 601 is provided on the positioning spring 7. After the claw 701 engages with the slot 601, a limiting structure is formed that can prevent the plug end contact 6 from moving in a direction perpendicular to the direction of the socket body and the socket body. It can be understood that other limiting structures that can provide limiting in a direction perpendicular to the direction of the socket body and the socket body are also possible.
[0036] As mentioned above, in other embodiments, the elastic element 11 can be disposed in the plug body. Understandably, it is only necessary to provide the plug end contact 6 with a compressive force that compresses the socket end contact 12 and the plug end contact 6 in the direction of abutment and mating between the plug end contact 6 and the socket end contact 12.
[0037] It should be noted that the parts not described in detail in this article are prior art. The above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
