Embodiment 1

[0017] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is composed of a plug 1 and a wire crimping end 2. The plug part 1 is in the shape of a cylinder with a closed side wall, and the wire crimping end 2 is a curved surface structure that retains part of the side wall. The crimping terminal is packaged by an injection molding machine, wherein, A circular plate cover 3 is arranged at the lower end of the plug part. The circular plate cover 3 is formed by punching, and is connected with the side wall of the lower end of the plug through a small connecting section 4. A step 5 is provided in the inner hole of the lower end of the plug, and the step is the smallest. The diameter of the inner hole is smaller than the diameter of the disc cover, and the disc cover 3 and the stepped hole are tightly fitted.

[0018] In practice, the cylindrical structure of the plug part may also be a square cylinder with a square hole. At this time, th...

Abstract

The invention discloses a crimping terminal structure for an electrical appliance connector. The structure consists of a plug and a crimping end, wherein the plug part is in a cylindrical form of which the side wall is closed; the crimping end has a curved surface structure of which the side wall is partially preserved; a crimping terminal is encapsulated by an injection molding machine; the lower end of the plug part is provided with a round board cover which is formed by blanking and connected with the side wall at the lower end of the plug by a small connecting section; steps are formed inan inner hole at the lower end of the plug; the minimal inner hole diameter of the steps is less than the diameter of the round board cover; and the round board cover and the stepped holes are in close fit. In the crimping terminal structure for the electrical appliance connector, the lower end of the through hole of the plug part is provided with the round board cover, and the through hole of the plug part is blocked by the round board cover during the injection molding of the connector, so that slurry is not leaked during the injection molding, and a blocking piece does not need to be welded manually. Therefore, the production efficiency of connector products is improved, the production cost is lowered and the reliability of the products is ensured.

Description

Technical field: [0001] The invention relates to the field of electric appliances, in particular to connectors for automobile electric appliances and household electric appliances, in particular to a crimping terminal structure for electric appliance connectors. Background technique: [0002] Connector products widely used in automobile electrical appliances and household electrical appliances are composed of plastic shells, crimping terminals and wires. First, the crimping terminals and wires are crimped together, and then they are packaged together using injection molding equipment and injection molds. , to complete the entire product production process, in which the crimping terminal material is various metals, and the product is produced by a cold stamping die. In order to facilitate crimping with wires, the wire connection part at the rear end of the crimping terminal is set as a U-shaped open curved surface in cross section, while its front end is a cylindrical structu...
