Composite embedded electric energy meter end button

Abstract

The invention discloses a composite embedded electric energy meter end button, which comprises an end button body and a current terminal (2) embedded in the end button body, wherein the end button body comprises bakelite (1) and plastic (3); the current terminal (2) and the bakelite (1) are formed into a bakelite terminal core row through thermosetting moulding; and the bakelite terminal core row and the plastic (3) are subjected to secondary injection moulding. The composite embedded electric energy meter end button, which is made through steps of current terminal and bakelite thermosetting moulding and plastic secondary injection moulding, combines the advantages of the two materials, effectively reduces the pollution to the environment, is low-carbon and environment-friendly, has high flexibility and strength, guarantees sufficient tensile force after the current terminal and an end button box are assembled, and greatly increase the heat-resistant temperature of the product.

Description

technical field [0001] The invention relates to a terminal button, in particular to a composite embedded electric energy meter terminal button. Background technique [0002] The terminal buttons currently used are mostly made of bakelite or polycarbonate + glass fiber (PC+GF) material. Bakelite is a thermosetting material with good heat resistance and rigidity and stable dimensions. It is easy to be damaged, and the material is not recyclable; the polycarbonate + glass fiber (PC+GF) material terminal button is a thermoplastic material, which has poor heat resistance and rigidity, and the tensile force of the terminal and its assembly is insufficient. [0003] Due to the defects of the above two materials, it can be seen that if bakelite is used for the original terminal button structure, the use of bakelite is large, and it is not recyclable. In the long run, it will cause immeasurable damage to the environment; the original terminal button is made of polycarbonate + glass ...

[0002] The terminal buttons currently used are mostly made of bakelite or polycarbonate + glass fiber (PC+GF) material. Bakelite is a thermosetting material with good heat resistance and rigidity and stable dimensions. It is easy to be damaged, and the material is not recyclable; the polycarbonate + glass fiber (PC+GF) material terminal button is a thermoplastic material, which has poor heat resistance and rigidity, and the terminal has insufficient pulling force after assembly

[0003] Due to the defects of the above two materials, it can be seen that if bakelite is used for the original terminal button structure, the use of bakelite is large, and it is not recyclable. In the long run, it will cause immeasurable damage to the environment; the original terminal button is made of polycarbonate + glass Fiber (PC+GF) material, poor heat resistance and rigidity, insufficient tension after the terminal and its assembly
