detailed description

The utility model will be described below in conjunction with specific embodiments.

As shown in Figure 1-3, a circular electrical connector with a double-shrapnel structure includes a cylindrical conductive body 1, and a circular crown spring 1 and a middle fixing ring 21 are set inside the conductive body 1. The upper end of the conductive body 1 is fitted with a crown spring 2 3, and the outer end of the conductive body 1 and the crown spring 2 3 is fitted with a cylindrical shell 4;

The crown spring one 2 includes a cylindrical crown spring main body one 22, and the upper end of the crown spring main body one 22 is provided with a plurality of shrapnel one 23 arranged in a circular arrangement and in the form of a cantilever beam;

The crown spring 2 3 includes two semicircular crown spring main bodies 2 31 , and the upper end of the crown spring main body 2 31 is provided with a cantilever beam-like shrapnel 2 32 which is reversely bent.

Further, the conductive main body 1 and the middle fixing ring 21 are in interference fit, so as to protect the elastic piece 1 23 from damage.

Further, the end of the elastic piece 1 23 is arranged between the conductive body 1 and the intermediate fixing ring 21 to protect the elastic piece 1 23 from damage.

Further, the end of the second elastic piece 32 is arranged between the middle fixing ring 21 and the housing 4 to protect the second elastic piece 32 from damage.

Further explanation is required, the utility model adopts the independent arrangement of the first row of shrapnel 23 and the second row of shrapnel 2 32, which does not interfere with each other and increases the anti-risk performance of the connector; while the shrapnel 1 23 and the shrapnel 2 32 adopt cantilever Beam structure, each single shrapnel moves independently, which makes the insertion and extraction force easy to control and increases wear resistance; shrapnel 2 32 adopts reverse bending method to save space, crown spring 2 3 is spliced by two semicircles to form a full circle , thereby reducing manufacturing difficulty and saving cost, so the utility model has the advantages of novel design, simple structure, avoiding damage to the shrapnel when external force is inserted, and making the crown spring durable and not easy to wear.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
