[0021] The present utility model provides a jack for an electric vehicle charging socket that is convenient for assembly.

[0022] Such as Figures 1 to 4As shown, in one embodiment of the utility model, the jack for an electric vehicle charging socket that is easy to assemble includes a jack body 100, an elastic structure 200 and a rubber ring 300. The jack body 100 and the elastic structure 200 are both made of conductive strips rolled into a cylindrical structure, which does not require the use of a variety of processing equipment for processing and production, saving space, reducing costs, and improving production efficiency. The jack body 100 includes a plug-in end 110 at the front end and a connecting end 120 at the rear end, wherein the inner side wall of one end of the plug-in end 110 near the connecting end 120 is uniformly protruded with at least 4 limiting protrusions 111 along the circumferential direction, and the outer side wall is correspondingly uniformly provided with a first groove 112 along the circumferential direction, and the position of the limiting protrusion 111 can be well positioned by the first groove 112, and the other end of the plug-in end 110 A second groove 113 is symmetrically concave along the axial direction, and the second groove 113 is respectively provided with a hook 1131 inwardly. The elastic structure 200 is elastically embedded in the plug-in end 110, and the two ends are respectively abutted against the limiting protrusion 111 and the hook 1131, and is effectively embedded in the plug-in end 110. By using the simple structure of the limiting protrusion 111 and the hook 1131, effective limiting fixation is achieved, the assembly structure is simplified, the efficiency is improved, and the cost is reduced. The elastic structure 200 is a waist-shaped elastic structure formed by twisting or bending inward. The elastic structure 200 is a waist-shaped structure formed by rolling a fence-shaped conductive strip and rotating it. The waist-shaped elastic structure can increase the contact area during insertion and ensure the contact strength. At the same time, the waist is moderately radially inward in the middle to facilitate elastic abutment with the contact point.

[0023] Specifically, the rolled joints of the elastic structure 200 and the socket body 100 are staggered in the radial direction, and the rubber ring 300 is sleeved on the middle position of the socket body 100. The size of the rubber ring 300 is just tightly matched with the middle position of the socket body 100, which is used for effective tightening and waterproofing, avoiding water seepage at the contact point of the socket and affecting normal operation. The front end of the connecting end 120 is provided with a conductor crimping structure 121, and the conductor crimping structure 121 is used to achieve crimping and fixation with the conductor inside the wire. The conductor crimping structure 121 is an open-type crimping structure, for example, U-shaped, and the plug-in end 110 is provided with a plurality of through holes 114 along the circumferential direction. The through holes 114 are respectively connected to the second groove 113 at intervals. A connecting plate 1141 is provided in the through hole 114. The connecting plate 1141 is a concave structure from the outside to the inside, which can effectively limit the contact with the pin.

[0024] Specifically, the working principle and process of the utility model are as follows: during assembly, the conductor crimping structure 121 is first used to crimp the wire, and then the rubber ring 300 is adapted, fixed, and sealed and crimped, and finally the product is inserted into the socket cavity. When in use, the pin first contacts the pre-contact protrusion of the socket, and the initial connection is completed to realize signal transmission. When continuing to go deeper, a stable contact is formed with the spring structure 200.

[0025] The utility model has the following advantages:

[0026] By combining the jack body rolled from a conductive strip, an elastic structure, and a rubber ring into a jack, the components are streamlined, the structure is simple, and the production process is concise, effectively improving production efficiency and reducing production costs;

[0027] Manufactured by the conductive strip rolling process, large-scale operations can be achieved with a single device, the comprehensive cost is low, and cost reduction and efficiency increase are effectively realized;
