Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] see Figure 1-Figure 7 , The shrapnel and the insertion piece of the relay include the shrapnel 1 and the insertion piece 2, which are formed by continuous stamping and fixedly connected.

[0030] see figure 1 , figure 2 , The shrapnel 1 is a long sheet with a zigzag cross-section, one end of which is provided with a positioning hole and a joint, and the other end is provided with two small holes 1a which are fixedly connected with the insertion piece 2 .

[0031] see image 3 , Figure 4 , the insert piece 2 is a strip with a zigzag-shaped cross section, and its thickness is thicker than that of the shrapnel 1. One end is a plug with a positioning hole, and the other end is provided with two upwardly convex protrusions corresponding to the two small holes 1a of the shrapnel 1. Edge 2a.

[0032] see Figure 5-Figure 7 , the fixing method ...

Abstract

The utility model relates to a fixing manner of an elastic piece and an inserting piece of a relay. The elastic piece is a stripy sheet, one end of the elastic piece is provided with a positioning hole and a joint, and the other end of the elastic piece is provided with at least one small hole and is fixed with the inserting piece; and the inserting piece is thicker than the elastic piece, one end of the inserting piece is a plug provided with a positioning hole, and the other end of the inserting piece is provided with a convex or concave flange corresponding to the small hole of the elasticpiece. The elastic piece and the inserting piece are molded by continuous punching and are fixedly connected, and specifically, are respectively formed by different metal plates through a progressivedie and are fixedly connected into a whole. By utilizing the fixing manner, the purpose that the elastic piece and inserting piece needed by the relay are produced simultaneously in one mold is realized by adopting the progressive die with reasonable design, and by arranging the small hole on the elastic piece and arranging the flange on the inserting piece, the elastic piece and the inserting piece are connected and then riveted together by extruding the flange. The fixing manner has the characteristics that the mechanical automation level is high, the rate of finished products is high, the mold cost is saved, the occupation of human resources is reduced and the production cost is reduced.

Description

technical field [0001] The invention relates to a relay, in particular to a shrapnel and an insertion piece of a relay, in particular to a fixing method for the shrapnel and the insertion piece of a relay. Background technique [0002] In the power relay, the action of the relay is realized by shrapnel, push card, etc., which requires the shrapnel to move flexibly, so the molding size of the shrapnel plays a vital role in the action and production efficiency of the relay; It is the port where the relay is connected to the external power supply. Generally, it is required to have a certain hardness so that it will not be deformed when it is connected to the external power supply. This results in the use of two different materials to meet this requirement. How to combine the two Combining parts with different materials and ensuring that the original dimensions of the two parts remain unchanged after riveting together is a major problem in the relay industry. [0003] At presen...
