0190980122 Terminals - Spade Connectors Application Field and Working Principle

Terminals – Spade connectors are the devices that can be used to interconnect or disconnect power circuits or signal circuits. They are the main components in the automation and wiring of electrical instruments or electronic devices. Generally speaking, terminators – Spade connectors include pins, terminals, couplings, terminal blocks and other parts. They are widely used in power, electric energy, electronics, telecommunications, transportation, medical and other industries.

Application Field

Terminals – Spade connectors are widely used in various fields, such as power generation, distribution and transmission, computers, telecommunications, medical and practical machinery. It has become an essential part of the electrical equipment industry and an indispensable commodity for engineering construction. In the development of modern intelligent equipment, it can be seen everywhere.

• In Power Generation, Distribution and Transmission Areas: Used for transmission, distribution, control and protection of power network and system.
• In Computer and Telecommunications Industry: Used in telecommunication base stations, data centers, network, etc.
• In Medical Industry: Used in medical printers, medical instrumentation, medical electronic equipment, etc.
• In Automobile Industry: Used in automobile test bench, auto diagnostic instrument, etc.

Working Principle

Terminals – Spade connectors are mainly composed of contacts, insulating components, shell and other components. There are mainly three ways of its working principle: Connecting, Disconnecting and Widening. Connecting and Disconnecting is the most common working principle. In this case, when the terminal - Spade connector contacts are connected, the current will flow through the contact system, and when the contacts are disconnected, the current will not be transmitted through the contact system. Widening is mainly used to increase the current carrying capacity of the contact between the terminals - Spade connectors.

Connecting and Disconnecting are very important interminals – Spade connector’s working principle. Its connecting and disconnecting effects depend on the design and installation of the contact system as well as the material of the conductive column and the contact pressure. Generally, to ensure good connection and disconnection effect, the contact surface should be smooth and made of copper; it should also have good conduction, corrosion resistance and contact pressure.

Generally speaking, to ensure the quality of terminals – Spade connectors, all the factors that may affect its performance should be taken into consideration, such as the material quality, the design and installation methods, the contact force, etc. In order to meet the different application requirements, there are many kinds of terminal – Spade connectors available on the market. With the development of the industry, their application fields are also expanding, so as to provide customers with more choice and better products.
