What is a power connector?

A power connector completes a circuit by connecting an electrical component to its power supply. For consumer electronics, the connector usually refers to the connection where the product "plugs" into the battery, or more commonly the power supply in the wall. Some types of electrical connectors carry both power and data, but power connectors have a more specialized purpose: they allow electronic devices to run.


Basic concepts of power connectors

The various power connectors on the market reflect their many differences in construction, direction, and purpose. Some connectors are resistant to physical damage caused by water, shock or vibration; Some people can only tolerate a limited number of connections and disconnections before possible failure. We classify power connectors as: 1. Connection duration (temporary or permanent). 2. Position of conductive interface (male or female) 3. Type of current (alternating or direct). 4. Assembly and disassembly methods.



Power connector Structure

For the power connector to perform its function correctly, it must have the correct pin arrangement. The pin arrangement is the connection arrangement that each connector can make within the circuit. Each wire is connected to the corresponding contact or pin in the connecting part. Since the wires may have different uses and characteristics, the function of the connectors and the entire circuit is essential, with each pin matched to the correct contact. Connector manufacturers use several different methods to make these wire connections, such as: 1. Welding. 2. Pierce or move the insulation around the contacts. 3. Wind the wire. Choosing the appropriate connection method depends on the end of the connector. The terminal exposed pins are just enough to complete a circuit, but not enough to create a dangerous connection prone to damage from normal use, or possibly accidental disconnection.



Power connectors keyed and polarized

Incorrectly connected pins may damage electrical components. To prevent connection errors, certain connectors have special mechanical adjustment features that only allow the connector to connect to the pin assignment for the correct match, Angle, and orientation. These connectors are called "keyed" or "polarized" connectors.
