A Brief Discussion Of Copper Terminal Blocks.

A connector copper distribution block is a type of device designed to facilitate wire connections. It typically consists of insulating parts, conductive parts, and solder pins.  copper terminal strip It has spring clips. copper terminal block This is a matter of process design, and Kangrui Electronics - Kangrui Connector manufacturer's technical personnel recommend considering the following situations:

1. Due to debugging, maintenance, and other factors, the wires at this location need to be frequently disassembled and assembled. For example, if two wires sometimes need to be connected and sometimes disconnected, a copper terminal block can be used for connection, allowing for easy disconnection without welding or wrapping, which is very convenient and fast. Most terminal materials are copper and aluminum. Choose the appropriate copper lug connection according to the cable core material. If the cable is copper wire and the equipment contact surface is aluminum, a copper-aluminum lug connection is required. The electrical products have complete specifications, high-purity copper, and a tin-plated surface, making them beautiful and durable.

2. As a whole, the electrical box or circuit board needs to be connected to other external circuits. Copper terminal blocks are used on PCB circuit boards. When a circuit fault occurs, the wires can be easily detected, avoiding the time-consuming and laborious process of removing wires from the circuit board.

3. A large number of wires need to be connected to the same equipotential point. Copper terminal blocks have holes at both ends, allowing wires to be inserted, tightened, or loosened with screws, suitable for interconnecting a large number of wires. The power industry has special terminal blocks and terminal boxes, with terminals covered in single-layer, double-layer, current, voltage, ordinary, and disconnectable types.

4. The wire diameter is large, making screw terminal connections inconvenient. Copper terminal blocks use crimping frames for connection, allowing for large wire diameters and protecting the wires from damage. Intermediate electrical products include C45 plug pins, DZ47 air circuit breaker wiring lugs, and duckbill copper lugs, making plug-in connections more convenient and faster for connecting C45-4 to C45-95 medium-voltage wires, power cables, and electrical equipment.

5. The current is large, requiring an increase in the contact area of ​​the electrical connection. Copper terminal blocks can meet the needs of high-current connections.

6. Multiple strands of wire need to be connected to the same terminal. Due to multiple jacks on the same terminal, wiring is convenient. BB bolt connectors can connect copper/aluminum/aluminum alloy cables. Mechanical connectors only require a socket wrench or spanner, eliminating the need for crimping tools and operator skills. The surface is tin-plated for oxidation resistance.

Nearly a hundred years have passed since the invention of the terminal. From the earliest combination terminals to various plug-in, direct-solder, barrier, spring terminals, and even bare terminals, a complete system of electrical interface technology has been formed in the connector field. Its application scope has also expanded to rail transit, security lighting, elevator power control, medical equipment, and other fields. Given the ease of installation and stable electrical performance of terminals, they are gradually gaining the trust of more customers.
