Terminal

Abstract

The invention discloses a terminal which comprises a plastic member and a plurality of copper inserts that are embedded into the plastic member. One end of each copper insert is provided with a threaded hole for connecting with a connecting wire. The plastic member is molded through a mold in an injection molding manner. The plurality of copper inserts are directly placed at corresponding positions in the mold. Fused plastic is injected into the mold and wraps the copper inserts so that the plastic member and the copper inserts are integrally molded, thereby realizing embedding of the copper inserts into the plastic member. The external surface of each copper insert is also provided with a plurality of longitudinal troughs and a plurality of circumferential troughs. In an injection molding process, molten plastic flows into the longitudinal troughs and the circumferential troughs, thereby realizing fixation between the copper inserts and the plastic member. The terminal of the invention has relatively large number of wiring ports. The terminal has advantages of relatively high sealing performance between the copper inserts and the plastic member, high connecting strength and attractive appearance.

Description

technical field [0001] The invention relates to the technical field of wiring device design, in particular to a watertight and beautiful wiring terminal. Background technique [0002] In the field of electrical equipment, terminals are often used for wiring. The terminal mainly includes a plastic part and a copper insert set on the plastic part. In the prior art, a through hole is first opened on the plastic part, and then the copper insert is installed in the through hole. This connection method, The watertightness between the plastic part and the copper insert is poor, and the phenomenon of spinning between the copper insert and the plastic part is easy to occur. [0003] In addition, the plastic parts of the terminal in the prior art are usually made of nylon material, and the existing plastic injection molded terminal is prone to blackening at the place corresponding to the gate, thus affecting the aesthetic effect of the terminal; Moreover, after the materials used fo...

The terminal mainly includes a plastic part and a copper insert set on the plastic part. In the prior art, a through hole is first opened on the plastic part, and then the copper insert is installed in the through hole. This connection method, The watertightness between the plastic parts and the copper inserts is poor, and the phenomenon of rotation between the copper inserts and the plastic parts is easy to occur

[0003] In addition, the plastic parts of the terminal in the prior art are usually made of nylon material, and the existing plastic injection molded terminal is prone to blackening at the place corresponding to the gate, thus affecting the aesthetic effect of the terminal; Moreover, after the plastic parts of the existing terminal blocks are made of materials, there will be lines or cracks, and the defective rate is relatively high.
