There is much electrical equipment in the car circuit that is connected by wires of different colors, and the most not to be ignored is the fuse. The fuse is the customary name, and it is called the fuse in the national standard. The function of the fuse is to protect the circuit (line) and electric...

A fuse is also called a current fuse, and the IEC127 standard defines it as a "fuse-link". It is mainly used for overload protection. If the fuse is properly placed in the circuit, the fuse will fuse and cut off the current when the current rises to a certain height and heat abnormally, which protec...

Relay (English name: relay) is an electrical control device. It is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the input quantity (excitation quantity) changes to meet the specified requirements. It has an i...

The antenna, this little thing, is an indispensable part of the wireless signal. Without it, that router can basically only be used in a single room. It is also an important element of appearance. The appearance of the router cannot be separated from the square or oval barrier, but manufacturers can...

Two conductors close to each other sandwich a non-conductive insulating medium between them, which constitutes a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the amount...

1. Board-to-board connector test inspection:1) Observe that the loading voltage on the board-to-board connector should not exceed 50% of its rated voltage.2) The installation size of the board-to-board connector. For the plug-in header, the length of the soldering feet on the soldered PCB requires t...

1. What is a board-to-board connector?The basic concept of a board-to-board connector is to connect different circuit boards together. It is the connector product with the strongest transmission capacity among all connector product types. It is mainly used in power systems, communication networks, f...

Common faults of terminal blocks:The meaning of preventionThe plastic insulating material and conductive parts of the terminal are directly related to the quality of the terminal, and they respectively determine the insulating and conductive properties of the terminal. The failure of anyone terminal...

The terminal block is a kind of accessory product used to realize the electrical connection, which is divided into the category of the connector in the industry. As the degree of industrial automation becomes higher and the requirements for industrial control become stricter and more precise, the am...

Overview:Consistent with the tradition of high standards of military products, military connectors are specially designed for the armed forces' needs for durable and highly reliable products. These connectors are of different shapes and sizes and are used in many fields from communication offices to...
