Description

Technical Field

[0001] This utility model relates to the field of connector terminal technology, and in particular to a terminal with optimized contact points. Background Technology

[0002] Terminals are widely used in automotive electronics, communication equipment, home appliances, and industrial automation equipment. Their performance directly affects the reliability of the entire system. With the trend of miniaturization and high speed in equipment, higher requirements are placed on terminal contacts, such as low contact resistance, high conductivity, and resistance to environmental influences. Traditional terminals require stable materials and designs under harsh conditions such as high temperature, high humidity, and vibration. At the same time, traditional terminal contacts are prone to increased resistance due to oxidation and contamination. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a terminal with optimized contact points, which can solve the problems of poor contact stability and easy increase in resistance due to oxidation and contamination in the prior art USB terminal products under harsh conditions.

[0004] This application provides a terminal with optimized contact points, including a contact plate, wherein the contact plate is provided with a first rib and a second rib, the contact plate is connected to a support plate by a second bend, and the support plate is connected to a connecting plate by a third bend.

[0005] Furthermore, the first and second ribs are round-headed elongated protrusions, and the first and second ribs are arranged in parallel in the middle of the contact plate to increase the contact area of ​​the product connection and reduce impedance.

[0006] Furthermore, the front end of the contact plate is provided with a first bend, which bends downward to improve the stability of the contact plate and ensure that the contact plate can make more stable contact with the contact area on the female head.

[0007] Furthermore, the second and third bends are provided with multi-stage stepped bends. These multi-stage stepped bends can serve to fix the support plate, prevent the terminals from shifting and failing to make contact with the contact area of ​​the female connector, and increase the mechanical strength of the second and third bends. When the equipment is subjected to vibration or impact, they can better disperse stress and ensure the reliability of the signal connection.

[0008] Furthermore, the connecting plate is connected to the support plate via a third bend. The connecting plate is shaped like a cleaver to increase the area for connection with the wires, facilitating signal transmission.

[0009] Furthermore, the terminal is shaped like a "Z" to allow the current to be distributed more evenly on the contact surface, avoiding excessive concentration of current in local areas that could lead to excessive local resistance.

[0010] Furthermore, the terminal surface is coated with a highly conductive metal layer, which can prevent oxidation and corrosion of the terminal surface.

[0011] Furthermore, the method for forming the terminal with optimized contact points is integral molding.

[0012] According to the terminal with optimized contact points provided in this application, the advantages compared with the prior art are as follows: by using two convex ribs, the contact area of ​​the product connection is increased, the impedance is reduced, and the stability in harsh environments is enhanced. By designing the terminal structure and using stepped bending at the bend, the mechanical strength of the terminal can be improved. When the equipment is subjected to vibration or impact, stress can be better dispersed, ensuring the reliability of the signal connection. At the same time, a metal with good conductivity is used, and a layer of highly conductive metal is plated on the surface of the terminal to prevent oxidation and corrosion of the terminal surface, thus solving the problem of increased resistance caused by oxidation and contamination.
