Terminal structure

Abstract

The invention discloses a terminal structure which is integrally formed by punching and comprises a hollow terminal head which is formed on a side wall with a butt seam and provided with a butting portion recessed toward the interior of a hollow terminal, a hollowed-out position is arranged on a side wall opposite to the butting portion and provided with an elastic limiting piece, a root of the elastic limiting piece is fixedly connected with an edge of the hollowed-out position, and the other end of the elastic limiting piece extends toward the interior of the hollow terminal in a suspended manner. The butting portion and the elastic limiting piece are simultaneously arranged on the head of the hollow terminal, so that the requirement of close contact of a plug and the terminal is met, plug in-and-out force is more stable when the plug is plugged in and out, and poor contact is avoided. In addition, contact area of the plug and the terminal is increased, so that heat concentration is eased while larger current can be resisted with no heat generated, and the service life of the terminal is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a hollow terminal structure with stable plugging force. Background technique [0002] The hollow terminal is a device connected with a round plug or a square plug. Patent 200620137529.9 discloses a hollow terminal structure that prevents deformation (such as figure 1 , figure 2 As shown), the terminal is provided with a clamping groove 12 and a clamping part 13 limited in the clamping groove 12 on both sides of the longitudinal butt joint 11 formed by stamping integral molding, so the structural strength of the terminal can be greatly improved, but because The structural feature of the butt seam 11 is formed on the side wall, so that a limit elastic piece cannot be set on the side wall, but only a limit elastic piece 21 can be set on the opposite side wall to clamp the plug, so that the plug When inserting, because the deformation of the unilateral limit shrapnel...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a terminal structure, which overcomes the problem of the butt joint between the terminal plug and the hollow terminal in the prior art due to stamping, which causes a relatively large deformation of the unilateral limit shrapnel, and the plug and the hollow terminal There are also fewer terminal contact surfaces, so the insertion force is unstable, and there are defects of poor contact after multiple insertions and extractions. What's more, when encountering a large current, it is easy to generate heat due to heat concentration and cause failure. defect
