Screw type square box electrical connector

Abstract

The invention discloses a screw-type square box electrical connector, which comprises a plastic body, on which are provided square grooves, wire inlet holes, terminal holes and screw holes; corresponding to each square groove, conductive terminals, square boxes are provided and screws, the square box includes a square body, a conductive terminal placement slot, a square box screw hole and a square box through hole; the conductive terminal is provided with a terminal through hole; the screw includes a polished rod part, a thread part and a screw head; the square box is located on the In the square groove, the conductive terminal placement groove is opposite to the wire inlet hole and the terminal hole; the conductive terminal is positioned in the terminal hole; the screw is inserted in the screw hole, the polished rod part faces the square box, and the polished rod part can pass through the screw hole of the square box, The terminal through hole and the square box through hole, the threaded portion can be threadedly connected with the square box screw hole, and the end of the threaded portion facing the polished rod portion can stop at the side of the terminal through hole facing the screw hole. The invention can make the screw type square box type electrical connector applicable to more wire end connection modes, and brings more convenience to users' wiring.

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
