Description

Terminal structure of electrical connector

The present invention provides a terminal structure of an electrical connector, in particular a terminal structure which can be firmly combined with an insulating base body, the terminal has a main body and an extended section which form a step of the outer diameter, and the turning portion on one side of the extending section faces in a vertical direction The connecting side is provided, and the indentation groove is formed on the surface of the turning part, and the insulating seat body is integrally formed on the outside of the at least one terminal, so that the difference between the main body and the extending section is formed, and the combination with the insulating seat body is not easy to loosen.

Press, power outlets are widely used in electrical products, such as portable audio or audio projectors (such as VCD, DVD, etc.), and information products, such as computers, notebook computers, mobile phones, etc. The power cable socket and the mains socket of the product are respectively inserted into the line, so that the product can obtain power for the user to operate.

The indispensable component inside the power socket is at least one metal plug. The traditional metal plug can be divided into hollow and solid. As shown in the tenth figure, the hollow metal terminal is tied to a metal plate, for example, a copper plate. The sheet is formed into a shape, and then one end is crimped into a cylindrical contact portion A, and the other end is extended with a flat terminal portion B. The contact portion A and the terminal portion B are integrally formed instead of the riveted connection. The missing of the hollow metal terminal is that, due to its crimp forming, the control of the force during the winding process is very important. If the force is too large or the force is insufficient, the two sides cannot be tightly engaged at the joint position. Easy to cause warpage or deformation of the board As a result, the defect rate of the product is improved, and the structural strength of the hollow metal terminal is poor. When the connector is inserted into the opposite type electrical connector, the metal terminal is easily deformed, twisted or broken, and the front edge of the chip curling package is included. Cohesive joints can form seams that can seriously affect the appearance of the product.

In view of the absence of the aforementioned hollow metal terminal, the related art has proposed a power socket having a solid metal terminal. As shown in FIG. 11, the socket C of the power socket has a solid terminal D and a terminal E, and a solid terminal D. In order to be worn in the seat body C, the solid terminal D is provided with a retaining ring D1 that abuts against the front side of the seat body C. The solid terminal D protrudes to the rear side of the seat body C and is provided with a connecting end D2, and the terminal E is connected with The connecting end D2 of the solid terminal D is riveted, and the solid terminal D is fixed in the seat body C. Since the solid terminal D is made by turning, the retaining ring D1 has a larger outer diameter than the solid terminal D, so the metal material The material needs to be at least equal to the outer diameter of the retaining ring D1 before it can be turned into a solid terminal D and a retaining ring D1. The scrap generated by turning accounts for about 40% of the whole, which causes waste of materials and recycling of waste, which is quite inconvenient. In fact, the manufacturing cost of the core terminal D will be greatly improved, and the riveting is required to increase the riveting equipment and processing cost, and if the connection terminal D2 and the terminal E of the solid terminal D are insufficient in riveting strength or Damaged by external force to loosen the riveting position , The high temperature will lead to poor contact, sparking off or situation, and seriously affect the safe use of the product.

However, the metal terminals inside the current power connector, whether hollow or solid, must consume a lot of time in the molding process during the manufacturing process, and the hollow terminal has poor structural strength, flexibility, and deformation. Or the fracture, the forming winding operation is quite troublesome, and the defect rate of the product is easy to be improved; the solid terminal must perform time-consuming and labor-intensive turning processing, and many processing wastes are difficult to handle, resulting in waste of resources.

Therefore, how to solve the current power connector terminals are easy to manufacture and process The problem and trouble of forming a defective product, and the insufficiency of the terminal structure and the trouble and inconvenience of loosening after being combined with the insulating body are the directions for the relevant manufacturers engaged in the industry to research and improve.

Therefore, in view of the above problems and deficiencies, the creators have collected relevant information, evaluated and considered them through multiple parties, and through years of experience in the industry, through continuous trial and modification, they have designed the main body and extension of the terminal. The segment forms an outer diameter step difference, and a connecting side extends in a vertical direction on the side of the extending portion, and the connecting portion has a digging groove on the surface of the turning portion. The difference between the main body and the extending portion allows the insulating seat to be firmly combined and the dent of the turning portion A new patent for the terminal structure of an electrical connector that reduces stress concentration in the bending process, is less prone to cracking, and enhances the strength of the terminal structure is born.

The main purpose of the present invention is that the terminal has an abutting portion on one side of the main body and an extending portion on the other side, so that the outer diameter of the main body is larger than the outer diameter of the extended portion, and the difference of the outer diameter is formed. Further, on the other side of the extending portion away from the main body, abutting side extending in the vertical direction is provided, and a turning portion is disposed on the side extension portion of the main body and the connecting side turning connection position, and a notch groove is provided on one side surface of the turning portion. After the preset power supply line is connected to the connection side of at least one terminal, and then at least one of the terminals and the preset power supply line are integrally formed as an insulating base body, so that the extension portion and the insulating base body are stably combined and are not easily loosened. For the purpose, the inflection portion between the extension portion and the connecting side has a dimple groove, which can reduce stress concentration and is less prone to fracture.

The secondary purpose of the present invention is that the main body has an obliquely tapered abutting portion and the other side is provided with an extension of the reduced outer diameter, and the outer diameter of the main body is larger than the outer diameter of the extended portion. Forming a step difference of different sizes and extending in the vertical direction on the other side of the extension a plate-shaped turning portion, and a surface of one side of the turning portion is provided with a dimple groove, which is V-shaped, U-shaped, rectangular or trapezoidal, etc., and then a connecting side is extended on one side of the turning portion, and is disposed on the connecting side. The connecting groove is formed by a V-shaped plate, a U-shaped plate, a rectangular shape or a ladder shape, and the preset power supply line can be assembled at the connecting groove; and the connecting side can also form a circular arc plate, a tapered plate or a plurality of shaped plates, etc. And a connecting hole is provided on the side surface of the plate connection for the predetermined power line to be pierced, and the connecting hole can be a circular hole, an elliptical hole, a rectangular hole, a polygonal hole or a plurality of holes.
