Terminals and connectors capable of transmitting large current

This creation is about connecting terminals, especially a connecting terminal whose board thickness is at least greater than 0.2 mm in order to transmit large current.

By the way, with the advancement of communication technology and electronic technology, electronic devices with various functions, such as mobile power devices that can be carried around for continuous power supply of mobile phones, mobile phones that allow people to communicate at both ends of the world, can satisfy people anytime, anywhere Walkman for listening to music and personal computer (Personal Computer) that can help people deal with various things have become indispensable tools in modern people's life and work.

In addition, all kinds of electronic devices (such as smart phones, tablet computers, desktop computers, notebook computers, digital cameras... etc.) usually have to be connected to each electronic device in order to receive electronic signals and power from the outside. The fuselage is equipped with a connector. Generally speaking, the connector refers to all the connecting components and accessories used in electronic signals and power supplies. It is a bridge for all signals. Its quality affects the reliability of current and signal transmission. It has an impact and is also closely related to the operation of electronic devices. Moreover, through the function of connectors, multiple electronic devices can be connected into a complete system, which can transmit electronic signals or power to each other. Therefore, the connectors are actually different Electronic devices are indispensable components for realizing predetermined functions.

Here is a description of the connector assembly currently used to transmit power. Please refer to Figure 1. The connector assembly includes a connector plug A1 and a connector socket A3. The connector plug A1 can be formed by a plug A body A11 and a plurality of plug terminals A2 are formed.
