a terminal block

Abstract

The invention discloses a connection terminal. The connection terminal comprises a reed, a connecting seat and a screw, wherein the reed is provided with a connecting piece inserted into the connecting seat; two sides of the connecting seat are each provided with a vertical sliding slot, and a sliding block is arranged in the sliding slot, and a rotating shaft is arranged on the sliding block; a winding column is arranged in the connecting seat; an annular groove is formed in the middle portion of the winding column; the rotating shafts are clamped in two sides of the annular groove; two endsof the winding column are each provided with a protrusion; a groove matching the protrusion is arranged in the bottom of the screw; a spring is arranged between the winding column and the connecting piece; a winding groove is formed in the outer circumference of the winding column; and a wire positioning through hole is formed in the middle portion, of the winding column, where the winding grooveis located. The connection terminal can effectively prevent the screw from loosening during the pulling process of the wire, thus effectively preventing the connection piece and the connecting seat from being in poor contact and improving the service life.

Description

technical field [0001] The invention belongs to the field of electrical components, in particular to a connection terminal, especially a connection terminal used on a socket. Background technique [0002] In the electrical system, the most commonly used is the terminal block. The terminal block is generally used for the connection of the circuit. The terminal block commonly used on the socket is generally the socket reed to connect the wire. The existing connection method is generally a connecting piece on the reed. , equipped with a connecting seat with a screw hole, insert the connecting sheet into the connecting seat, and then fix the connecting sheet on the connecting seat with screws, the wire is welded on the screw and fixed on the screw with the rotation of the screw, preventing the wire The solder joints with the screws come off. [0003] In the long-term use process, it is inevitable that the wires will be pulled, causing the wires to provide a force to unscrew the...

Problems solved by technology

[0003] In the long-term use process, it is inevitable that the wires will be pulled, causing the wires to provide a force to unscrew the screws. If things go on like this, the screws will become looser and looser, and finally lead to poor contact between the connecting piece and the connecting seat or even detachment
