Tool-less terminal block

Abstract

The invention discloses a tool-free terminal block, which comprises an insulating main body, a conductive terminal, a shrapnel and an insulating sliding body. The insulating main body is provided with a wire inlet hole, and the shrapnel can be rotatably positioned on the insulating main body through a rotating column. The shrapnel It includes the crimping arm, mounting part, sliding arm and reset arm formed by bending in sequence. The mounting part is mounted on the rotating column, and the insulating sliding body slides up and down on the insulating main body. The insulating sliding body can drive the sliding arm and drive the shrapnel when it goes down. Rotate to the wire locking position, so that the crimping arm and the conductive terminal lock the wire inserted into the wire inlet hole; the upward movement of the insulating sliding body can drive the sliding arm and drive the shrapnel to rotate to the release position, so that the crimping arm and the conductive terminal release the incoming wire The wire in the hole; and at the wire locking position, the force direction of the sliding arm on the insulating sliding body is perpendicular or nearly perpendicular to the sliding direction. The invention adopts a novel structure that drives the shrapnel to rotate, so that the wiring is more stable and reliable, and is not affected by external forces.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a tool-free terminal block that can be quickly connected and disconnected without using tools. Background technique [0002] The terminal block is also called an electrical connector. The terminal block can quickly realize the connection between wires and wires, wires and circuit boards, and circuit boards. It is an indispensable part of electronic equipment and has more and more applications. The form and structure of the device are ever-changing. With the different application objects, frequency, power, application environment, etc., there are various terminal blocks with different structures. [0003] Rotary shrapnel lock type terminal block usually includes an insulating body, a conductive terminal, a shrapnel and a handle for driving the shrapnel to rotate and lock the wire. The conductive terminal is positioned and installed on the insulating body, and the shrapnel can ...

Problems solved by technology

However, the body of the handle barb with this structure is not large enough, and it is easy to cause the shrapnel rebound force to be greater than the handle’s anti-off force due to the excessive compression of the shrapnel during wiring or when the shrapnel touches the wiring, resulting in the handle loosening, releasing the shrapnel, and the wiring falling off
