Power socket, metal plugs thereof and method for making metal plugs

Abstract

The invention relates to a power socket, which comprises at least two metal plugs and an insulating socket, wherein the two metal plugs are formed into integration by punching and bending a solid cylindrical metal wire; one end of each metal plug is provided with a solid cylindrical contacting part, while the other end is a flat terminal part; the top end of the contacting part is provided with a circular arc head; and the insulating socket is a solid object formed by ejecting plastic so as to cover and fix the at least two metal plugs and form a plug hole on one surface of the base for accommodating and positioning the at least two solid cylindrical contacting parts, and the other surface is used for exposing at least two flat terminal parts. In particular, the invention further provides the metal plugs used for the power socket and a method for making the metal plugs.

Description

technical field [0001] The invention relates to a power socket, especially a solid metal pin with a cylindrical contact part at one end and a flat terminal part at the other end. The metal pin is integrally formed by stamping and bending, and is embedded in plastic Injection molding technology is used to form a power socket. In particular, the present invention further provides a metal plug for a power socket and a method for making the metal plug. Background technique [0002] According to the power socket, it is widely used in electrical products, such as portable audio or DVD players, and information products, such as computers, so that the power cord with plugs at both ends can be inserted into the power socket of the product and the mains socket respectively. The product obtains power for operation by the user. [0003] The indispensable components inside the power socket are at least two metal pins. The traditional metal pins can be divided into hollow and solid. The...

Problems solved by technology

In addition, in order to manufacture the solid contact pin, turning and riveting processes are also added, resulting in higher production costs. The outer diameter of the retaining ring 201 is the original outer diameter of the solid metal cylinder, and the solid contact pin 20 and the retaining ring 201 can be formed after turning, and the removed material accounts for about 40% of the whole, making the manufacturing cost difficult. reduce

In particular, if the riveting strength between the solid contact pin 20 and the terminal 30 is insufficient, or is affected by external force damage, the riveting position between the two is likely to be loosened, resulting in high temperature, sparks or falling off caused by poor contact. Seriously affect the safety of the product, and urgently need the improvement of the relevant industry
