A split plug and method of making the same

Abstract

The invention discloses a split-type plug and a manufacturing method thereof and belongs to the electrical connecting device field. The split-type plug comprises a plugging-bolt shell, a power supply electrode, a grounding electrode and an electrode fixation insertion block. The plugging-bolt shell possesses a cavity, wherein an assembling port is arranged above the plugging-bolt shell. A side wall of the plugging-bolt shell is provided with a power supply electrode bayonet and a grounding electrode bayonet which are connected to the cavity respectively. The power supply electrode and the grounding electrode are assembled in the plugging-bolt shell. And contact points of the power supply electrode and the grounding electrode are wedged into the corresponding power supply electrode bayonet and the grounding electrode bayonet. The electrode fixation insertion block is inserted into the plugging-bolt shell through the assembling port so that the power supply electrode and the grounding electrode are fixed between the plugging-bolt shell and the electrode fixation insertion block. The invention also discloses a manufacturing method of the split-type plug. By using the plug and the method, a defective rate of the product is reduced; even if there is a defective product, a metal electrode can still be recycled; resource wastes are avoided and production efficiency is greatly increased.

Description

technical field [0001] The invention relates to a plug for electrical connection and a manufacturing method thereof, more specifically, to a split-type plug and a manufacturing method thereof. Background technique [0002] At present, in order to overcome the disadvantages of unsafe electrical connection and poor reliability of the traditional two-hole and three-hole plugs and sockets, some new plugs and sockets have appeared on the market, which have also changed the existing electrical connection methods. For example, Chinese Patent No. ZL200910127119.4 discloses a rotary electrical connection device and its plug and socket. This type of rotary electrical connection device generally inserts a circular plug with metal contacts on the outer wall into a socket with a round hole. The contact between the plug and the socket is connected by rotating 90°. Generally, there are two situations for pulling out the plug and socket. One is to rotate the plug in the opposite direction a...

Problems solved by technology

In the production of this kind of plug, the traditional method is to put the power electrode and the ground electrode into the mold together as inserts, and then inject the insulating plug material into one body. The fixing in the middle is troublesome and takes a long time. During the mold clamping process, the mold often squeezes the insert aside, resulting in a high defective rate of the molded plug and low production efficiency. Moreover, due to the electrode and the plug The bolting material has an integrated structure, and unqualified plugs are also difficult to recycle electrodes for reuse, resulting in waste of resources and increased costs

In addition, in the traditional manufacturing process, in order to facilitate the processing and production of the electrode, the existing solution is to separately manufacture the metal contact and the conductive rod, and then rivet the metal contact and the conductive rod together, but this approach does not consider Due to the problem that the riveting of the metal contact and the conductive rod is easy to loose, it is easy to cause the metal contact to detach during use; in addition, after the metal contact and the conductive rod are riveted separately, although there is surface contact between the metal contact and the conductive rod , but there will be more or less gaps. Practice has found that after this kind of electrode is energized, there will be obvious heating between the metal contact and the conductive rod, resulting in a short service life of the plug.
