Wire Ferrule is a kind of terminal block accessories, which is usually used for assembling electrical wires and cables in order to ensure safe and reliable electrical power transfer. 900591 Application Field and Working principle is a subsection of this topic, which focuses on the application of the wire ferrule in the power supply and its internal function principle.

Application field

Wire ferrules are widely used in various fields such as industrial automation, electrical power supply, electronic product wiring, etc. Generally, the wire ferrule can be divided into three series: UL, CE, and CCC. Different series have different usage and application. The wire ferrule is mostly used for the connection between copper and copper, copper and aluminium, or aluminium and aluminium wires. As the type of wire ferrule varies, the number of terminals and the outer diameter of the cable are different, so it can meet the different needs of customers.

UL series of wire Ferrule is mainly used in the North American power supply connection, which is developed to meet UL approved standards; CE series is suitable for European standard connection; while CCC power connection is applicable to the Chinese market with national standard connection requirements.

Working principle

Wire Ferrule consists of two parts: the body and the terminal. The body is made of insulation material, which can effectively prevent insulation damage due to external factors. Based on the property of this material, the connection between the wires can also be locked, which makes the connection more reliable.

The terminal is composed of two parts: the contact and the spring. The contact is made of copper material, which has excellent electrical conductivity and can ensure the transmission of current. The spring is used to hold the wire in the terminal block to ensure reliable contact between the wires and the terminals. With the help of the spring, the wires can be firmly connected to the terminals and not easily fall off.

In addition, some specific special wire ferrules also have extra screws to ensure stronger connection. Through the screws, the pressure of the connection is increased, which makes the connection more secure. The combination of the three mentioned components, namely the body, the terminal and the accompanying screws, make up the working principle of the wire ferrule.
