Introduction To The Types Of Copper Terminal Blocks

copper terminal block is a general term, including many types, each type is divided into many specifications. The number of terminal points in each row of terminal blocks is different, and its model can be determined according to the needs of engineering technical parameters. Generally, we can see more terminals such as plug-in terminals, fence terminals, spring terminals, rail terminals, etc. Next, the common copper distribution block specifications will be briefly introduced. Let's take a look!
Plug-in type
It consists of two plug-in connections. One part compresses the wire and then inserts the other part, which is soldered to the PCB. This shockproof design is based on the mechanical principle of the bottom, which ensures the long-term airtight connection of the product and the reliability of the finished product. Assembly ears can be added to both ends of the socket. The assembly ears can protect the connector to a large extent and prevent the connector from being poorly arranged. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. The socket can also have an assembly button and a locking button. The assembly button can be more firmly fixed on the PCB board, and the locking button can lock the mother body and the socket after the installation is completed. A variety of socket designs can be matched with different plug-in methods, such as horizontal, vertical or inclined printed circuit boards, etc. , and different methods can be selected according to customer requirements. You can choose metric gauge or standard gauge, which is the most popular terminal type in the market.
Fence
It can achieve safe, reliable and effective connection, especially in high current and high voltage environment.
Spring type
It is a copper terminal strip with spring device, which has been widely used in the world electrical and electronic engineering industry: lighting, elevator control, instrumentation, power supply, chemical and automotive power supply, etc.
Test terminal
The sliding metal piece that acts as a switch can withstand large working current through the terminal crimping wire frame. When switching, loosen the screw with a screwdriver and move the slider, and the switch position is clear at a glance; both ends are equipped with test sockets, which can be connected to the corresponding test terminals, and the current can be measured uninterruptedly. It can connect the control circuit with voltage of 660V and current of 57A.

The color is gray and can be installed on U-shaped or G-shaped tracks. The wiring capacity of the double-layer terminal in the same position is twice that of the general terminal. The upper and lower layers are staggered by 2.5mm in design, which is not only visually coherent, but also in the case of wiring on the upper layer, the screwdriver can easily wire in the lower area, and the marking is clear.
