Screw type square box electric coupler

Abstract

The invention discloses a screw type square box electric coupler which comprises a plastic body. Square grooves, wire inlet holes, terminal holes and screw holes are formed in the plastic body, a conductive terminal, a square box and a screw are arranged corresponding to each square groove, and each square box comprises a square body, a conductive terminal containing groove, a square box screw hole and a square box through hole. A terminal through hole is formed in each conductive terminal. Each screw comprises an unthreaded part, a thread part and a screw head part. The square boxes are arranged in the square grooves, and the conductive terminal containing grooves are opposite to the wire inlet holes and the terminal holes. The conductive terminals are located in the terminal holes. The screws are arranged in the screw holes in a penetrating mode, the unthreaded parts face the square boxes and can penetrate through the square box screw holes, the terminal through holes and the square through holes in sequence, the thread parts can be in threaded connection with the square box screw holes, and the ends, facing the unthreaded parts, of the thread parts can be stopped on the sides, facing the screw holes, of the terminal through holes. The screw type square box electric coupler can be applied to more electric wire tail end connection means, and more convenience is brought to wiring of users.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a screw type square box electrical connector. Background technique [0002] Electrical connectors can quickly realize the connection between wires and wires, wires and circuit boards, and circuit boards. Different application objects, frequency, power, application environment, etc., there are various electrical connectors with different structures. At present, the connection methods between electrical connectors and wires mainly include screw type, spring type, piercing wire insulation, and cold-pressed terminals at the end of wires. Screw-type electrical connectors are usually used to quickly connect wires. Screw-type electrical connectors are divided into two types: square box type electrical connectors and grid type electrical connectors. Square box type electrical connectors can be directly connected and peeled off. Insulated bare wires can also be connected to the end of the wire...

AI Technical Summary

Problems solved by technology

[0003] However, existing screw-type square box electrical connectors can only be used to connect bare wires with insulation peeled off or wires with round bar terminals crimped at the ends of the wires, and cannot be used to connect ring terminals and fork terminals crimped at the ends of the wires. The wire type of the terminal, otherwise the wiring connector needs to be replaced with a screw type grid type wiring connector
