Automatic bouncing structure for screw type electric coupler

Abstract

The invention discloses an automatic bouncing structure for a screw type electric coupler. The automatic bouncing structure for the screw type electric coupler comprises a screw, a supporting terminal, an L-shaped current-conducting plate and a spring sheet. The current-conducting plate comprises a flat plate part arranged horizontally and an outgoing pin part arranged vertically, the flat plate part is in a sheet shape, the outgoing pin part is in a bar shape, and one end of the outgoing pin part is fixedly connected to one side of the flat plate part. A screw hole matched with the screw is formed in the middle of the flat plate part, and a first through hole is formed in the side, close to the outgoing pin part, of the screw hole. The screw is located above the flat plate part and directly faces the screw hole. One end of the supporting terminal is fixedly connected with the screw in a detachable mode, and the other end of the supporting terminal penetrates through the first through hole and is fixedly connected with the spring sheet. The spring sheet is located below the flat plate part, and the supporting terminal can vertically compress the spring sheet to enable the screw to be connected with the screw hole. According to the automatic bouncing structure for the screw type electric coupler, the spring sheet is adopted to replace a spring used in the prior art to achieve automatic bouncing up of the screw, the transverse size of the plastic body of the electric coupler can be reduced effectively, and micromation development of the screw type electric coupler is promoted.

Description

technical field [0001] The invention relates to a screw-type electrical connector structure, in particular to an automatic spring-up structure of the screw-type electrical connector. Background technique [0002] Electrical connectors can quickly realize the connection between wires and wires, wires and circuit boards, and circuit boards and circuit boards. They are indispensable components in electronic equipment, and their application fields are becoming more and more extensive. Depending on the application object, frequency, power, application environment, etc., there are various electrical connectors with different structures. The connection methods between the electrical connector and the wire mainly include screw type, spring type, piercing the wire insulation, and cold-pressed terminals at the end of the wire. Screw-type electrical connectors usually use screws to quickly lock and connect wires. In the unlocked state of the screw-type electrical connection, in order...

Problems solved by technology

However, the above-mentioned automatic spring-up structure of the screw usually sets the spring vertically on one side of the screw, see figure 1 , corresponding to the spring, a groove for accommodating the spring needs to be designed on the plastic body, resulting in an increase in the lateral size of the plastic body, which is not conducive to the miniaturization development of electrical connectors, thus restricting the expansion and application of electrical connectors
