The part of a battery that is connected to an external conductor.

In electrotechnics, terminal refers to terminal, also known as terminal, which is divided into single hole, double hole, socket, hook and so on. In terms of materials, there are copper-silver plating, copper-zinc plating, copper, aluminum, iron and so on.

Their function is mainly to transmit electrical signals or conduct electricity.

In engineering, it is the interface reserved in front of the station for the post-station project, and it is the embedded facility of the post-station interface project.

The invention can generate an upright three-dimensional space image when observing an object, and has strong stereoscopic impression, clear and wide imaging and long working distance; It is equipped with a high-precision measurement and analysis system for the picture of the wire harness terminal, which is combined into a perfect combination of a wire harness terminal detection microscope, a high-quality optical system and a high-resolution camera to make the cross-sectional image clearer, and the unique scaling and setting make the measurement more accurate.

"port" is a free translation of English port, which can be considered as the exit of communication between equipment and the outside world. Ports can be divided into virtual ports and physical ports, where virtual ports refer to the ports inside the computer or in the switch router and are invisible. Such as port 80, port 2 1, port 23, etc. Physical ports, also known as interfaces, are visible ports, RJ45 network ports on the computer backplane and RJ45 ports, such as switch router hubs. Phones using RJ 1 1 jack also belong to the category of physical ports.
