The terminal block is actually one of the connectors, which is used for the connection of the wires. It is actually a piece of copper sheet enclosed in an insulating plastic, with holes on both sides, which can be inserted into the wires. With the development of the electronics industry, the application scope of terminal blocks is getting wider and wider. At this stage, the key applications are in power engineering control, machine equipment control, automation control, intelligent security control, instrumentation and other industries. If there was no application terminal before, the copper wire was directly connected to the screw. If the terminal is used, the safety is much higher and it is unlikely to fall off. Its tail end is also insulated.
There are holes on both sides of the terminal block for inserting wires, and there are screws for tightening or loosening. For example, two wires must sometimes be connected and sometimes they must be broken. At this time, you can use terminal blocks to connect them. It can be cut off at any time without welding or coiling them together, saving time and effort. And it is suitable for many wire interconnections. In the power industry, there will be special terminal strips, terminal boxes, all of which are terminal blocks, single-layer, two-layer, current, working voltage, general, and breakable. . A certain crimping area is to ensure reliable contact and to ensure sufficient current flow.
The terminal block is a basic accessory, which is used to extend from screws and screws to be used in the field of electrical connection and control, taking into account the requirements of ruggedness, safety, beauty and convenience. With the advancement of labor costs in society, the demand for terminal blocks is also getting higher and higher. Its main manifestations are as follows:
(1) Control box industry: complete sets of household appliances, power engineering protection, power generation control equipment, power control boxes and other control integrated systems include boxes, power switches, fuses, meters, dashboards, data signal control, etc. Control components, multi-purpose track terminals for large current control lines;
(2) Electronic component parts, instrument panels, controllers, relays, power meters, power switch control systems and other electronic components in the control cabinet. The connection and output terminals for electrical and control functions and separate lighting and switching power supplies. , Motors, instrumentation equipment, automatic machinery control, etc. The terminals for connection and output of electricity and control functions.
A terminal block is a kind of accessory product used to achieve electrical connection. It is industrially classified as a connector level. With the increasing level of industrial control automation and the increasingly stringent and precise industrial control regulations, the use of terminal blocks has gradually increased. With the development of the electronics industry, the main uses of terminal blocks are becoming wider and wider, and the types are increasing.
