Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

First embodiment of the present utility model: as shown in fig. 1-3, a terminal for plugging pins comprises a sleeve 1, wherein the sleeve 1 is provided with a cavity, an opening is formed in the bottom of the sleeve 1, a connecting block 2 is installed in the cavity of the sleeve 1, a convex ring 11 is arranged at the upper end of the sleeve 1, a plugging hole 12 is formed in the center of the convex ring 11, a fixing block 22 is arranged on the connecting block 2, a reed 21 is fixedly connected to the upper end of the fixing block 22, and a fixing welding part 23 is fixedly connected to the lower end of the fixing block 22. At least two reeds 21 are arranged at the upper end of the fixed block 22. The spring 21 has an arcuate shape, and the spring 21 is elastically deformed. The fixed block 22 is fixed in the cavity of the sleeve 1 by a mosaic connection. The connection part of the plug hole 12 and the convex ring 11 is designed as a chamfer angle. The chamfer is designed into an oblique angle structure, and the chamfer is designed into a round angle. The sleeve 1 is composed of copper material.

From the above description, the present utility model has the following advantageous effects: according to the utility model, the plug pin is clamped by the arc-shaped spring 21 with elastic deformation in the sleeve 1, so that good electrical connection is realized between the plug pin and the spring 21. The bow reed 21 of the utility model can prevent the looseness between the reed 21 and the plug pins after the terminals are plugged for a plurality of times, and still maintain good electrical connection.

Second embodiment of the utility model: as shown in fig. 1 to 3, in the practical application process of the terminals, the sleeve 1 is made of plastic, and in order to meet the volume requirement of the electronic equipment, the terminals need to be closely adjacent to each other to reduce the volume occupation, and because the conductive metal sleeves 1 are not mutually attached, a certain gap is reserved to prevent the terminals from being shorted, so that the arrangement of the terminals needs to occupy a large amount of volume of the electronic equipment, the terminals can be closely attached by adopting the non-conductive plastic sleeve 1, and no gap exists between the terminals, so that the volume of the electronic equipment occupied by the arrangement of the terminals is reduced, and the design volume of the electronic equipment is reduced.

Third embodiment of the utility model: the sleeve 1 is provided with the convex ring 11, the center of the convex ring 11 is provided with the inserting hole 12, the joint of the inserting hole 12 and the convex ring 11 adopts a chamfer design, the chamfer design can be of a bevel angle structure and a round angle design, and the sleeve can assist in inserting the inserting pins into the inserting holes 12 rapidly and accurately to finish the electric connection operation.
