Plug internal frame and combined conformation thereof with terminal

Abstract

The invention relates to an inner frame of a plug and an assembly structure of the inner frame of the plug and a terminal; the inner frame comprises a base; blocking tenons are respectively arranged on two corresponding outer sides of the base; the blocking tenon comprises a first valve body which is provided with a hook edge and is corresponding to the hook edge and a second valve body; a cutting groove is arranged between the two valve bodies; the flexible space of the first valve body and the second valve body for compressing and loosening is arranged owning to the space of the cutting groove; the two terminals are respectively arranged on the two outer sides of the base, and each terminal is provided with a penetrating hole which is used for leading the blocking tenons to penetrate and extend and to be forced to support for forming combination. L-shaped retaining walls at outer sides are utilized for effectively limiting probability of arbitrary swinging of the terminals, thus being beneficial to injection molding operation in post processing procedure; the exposed length of the terminal can be effectively controlled, thus leading the terminal to be in accordance with the requirements of safety standard.

Description

technical field [0001] The invention relates to a plug inner frame structure. Background technique [0002] In general daily life and industrial operation, the use of electrical appliances or electrical appliances, the power source of the alternating current is mainly to rely on a wire plug to connect with a socket, and conduct current to the electrical appliances or electrical appliances. Generally, the operation method of plug injection molding is to put the terminal into an inner frame body after the crimping operation is completed, and then put it into the mold of the plug shell for integral injection molding. It can be seen that in this background technology, there is an inner frame with the function of clamping the terminals, mainly in the hole provided in the inner frame to provide the insertion of the terminal, and there are two corresponding protrusions on both sides of the hole wall, but The problem is that since the terminals must pass through the holes, it is ea...

AI Technical Summary

Problems solved by technology

It can be seen that in this background technology, there is an inner frame with the function of clamping the terminals, mainly in the hole provided in the inner frame to provide the insertion of the terminal, and there are two corresponding protrusions on both sides of the hole wall, but The problem is that since the terminals must pass through the holes, it is easy to cause scratches on the surface of the terminals on the way through; , there must be enough space, so the material is more expensive

[0003] There is also an inner frame without clamping function. Although its structure is simple, the problem is that it has no clamping structure and function when placed inside the mold of the plug shell. Therefore, during the process of forming a plug shell through integral injection molding, Since the injection molding is carried out under the conditions of high temperature and high pressure, the qualified rate of the finished plug is often not good, and the exposed length of the terminal is affected, which does not meet the requirements of safety regulations.
