Description

Technical Field

[0001] The invention relates to the technical field of electrical connection, in particular to a wire spring socket. Background Art

[0002] Connectors are important devices for conducting current. In modern industry, especially in electrical appliances, connectors are widely used. As an important component of connectors, metal terminals have high requirements for their manufacturing and processing, and strive to be economical and simple to control costs. At present, most metal terminals use a combination of wire spring sleeves and pins. The wire spring sleeve includes a sleeve body, a sleeve cap and multiple wire springs, and the sleeve body has a socket. Insert multiple wire springs into the socket, and the wire springs are closely arranged around the edge of the sleeve body. The part extending out of the socket is bent toward the outer wall of the sleeve body, so that the wire spring is hung on the port of the socket, and then the sleeve cap is put on this end of the sleeve body, so that the part of the wire spring extending out of the socket is located in the gap between the inner wall of the sleeve cap and the outer wall of the sleeve body. The sleeve cap and the sleeve body adopt an interference fit and are fixed by the part of the wire spring extending out of the socket. However, the wire spring socket has many wire springs and the assembly of the wire springs is currently done manually. Therefore, the assembly is time-consuming and inefficient, which invisibly increases the manufacturing cost of the product. At the same time, since most existing wire spring sockets are not compact in structure, the effective contact area of ​​the wire spring is small during use, resulting in a short service life and high contact resistance.

[0003] For this reason, Figure 1 As shown, Chinese patent CN200910208863.7 discloses a wire spring plug sleeve, which includes a cap 4 and a body 1, wherein the body 1 has a socket, and the cap 4 is fixedly connected to one end of the body 1 to form a gap, wherein a plurality of slots 2 are provided on the edge of one end of the body that matches the cap, and one end of the wire spring 3 is located in the socket 11, and the other end of the wire spring 3 passes through the slot 42 and is clamped in the gap formed by the cap 4 and the body 1. A groove 12 is provided at the bottom of the socket, and the wire spring plug sleeve also includes a positioning plug 2, which includes a portion located in the groove 12 and a portion located in the socket 11, and a gap is formed between the portion of the positioning plug 2 located in the socket 11 and the inner wall of the body 1, and the other end of the wire spring 3 is located in the gap.

[0004] However, the wire spring socket disclosed in the patent has the following defects: on the one hand, the front end cap occupies more space, making the overall structure not compact; on the other hand, the existence of the cap 4 and the positioning plug 2 makes the structure too complicated, the manufacturing cost is high, and the process is cumbersome.
