Fence Terminal Blocks, also known as fence terminals or bar terminals, are modular wiring systems used for electrical connections. They provide a convenient way to connect multiple wires to a circuit board or electrical control panel without the need for soldering. The design of fence type terminal blocks allows users to quickly connect or disconnect wires through a screwdriver or similar tool.

characteristic:

Modular design: Fence type terminal blocks usually appear in the form of individual terminals or rows, and can be combined according to needs, making them very flexible.

Easy to connect: With a simple screw fixing mechanism, wires can be quickly connected to terminals for easy installation and maintenance.

Clear identification: Each terminal usually has enough space for marking, which helps to identify and record the connected wires and circuits.

Reliable electrical contact: The metal plates inside the terminals ensure good electrical contact, reducing contact resistance and potential fault points.

Structural composition:

The basic structure of fence type terminal blocks includes:

Insulated base: Provides mechanical support and electrical isolation, usually made of plastic.

Metal terminal block: used to fix wires, usually made of materials with good conductivity such as copper or copper alloy.

Fixed screws: used to tighten wires, ensuring the stability and reliability of electrical connections.

Spacer: used to maintain distance between terminals and sometimes also to provide additional mechanical support.

Common types:

The common types of fence type terminal blocks include:

Single layer terminal: Each terminal has only one wiring position, suitable for simple wiring needs.

Double layer terminals: Both upper and lower layers can be wired, saving space and suitable for dense wiring environments.

Spring type terminals: use springs to clamp wires, without the need for screws to fix, making installation quick and easy.

Grounding terminal: specifically used for connecting grounding wires to ensure safety.

Application:

Fence type terminal blocks are widely used in various electrical engineering fields, including:

Industrial automation and control systems

Building automation and distribution panels

Telecommunications and data communication equipment

Medical equipment and instruments

Power distribution and conversion equipment

When selecting suitable fence type terminal blocks, it is necessary to consider the specifications of the wires, the required connection strength, space limitations, and the convenience of installation. The correct selection and use of fence type terminal blocks are crucial for ensuring the reliability and maintenance convenience of electrical systems.
