Terminal is applied for the convenience of the connecting wires, it actually is a seal in the insulation inside the plastic pieces of metal, with a hole at both ends can be inserted into wires, screws for fastening may loosen, such as two wire, sometimes needs to connect, disconnect sometimes demand, then can use the terminal to connect them up, and can be disconnected at any time, without welding them up maybe around together, very convenient. And suitable for a lot of wire interconnection, in the power industry has a special terminal row, terminal box, above all are terminal terminals, single layer, double layer, current, voltage, general, can be broken and so on. Certain compression areas are required to ensure solid contact and sufficient current flow.
Type of terminal
1. Plug type
It is formed by connecting two parts of plug and pull. One part compacts the wire and then inserts it into the other part, which is welded to the PCB board. The mechanical principle of the connection bottom, the anti-vibration design ensures the long-term airtight connection of the product and the application of the finished product. Socket can be added at both ends of the device ear, the device ear to a large extent can protect the piece and can avoid the piece is placed in the wrong position, together with this kind of socket design can ensure that the socket can be correctly inserted into the mother. The socket can also have a device to buckle and determine the buckle. Device buckle can be more firmly fixed to the PCB board, determine the buckle can be determined after the completion of the device and the socket. A variety of socket design can allocate different maternal insertion method, such as: horizontal, straight or skewed to the printed circuit board, according to the customer's requirements to choose a different way. You can choose either metric wire gauge or standard wire gauge, which is the most popular terminal type on the market.
2. Fence
Safe, reliable and useful connections can be made, especially in the application of large current and high voltage environments.
3. Tension spring
It has been widely used in the international electrical and electronic engineering industry: lighting, elevator control, instrumentation, power supply, chemistry and automobile power.
4. Track device
It is widely used in the fields of power electronics, communication, electrical control and power supply.
5. Trajectory
Adopt pressing thread and common thread self - lock design, make the connection secure and secure. This series wiring terminal has a beautiful and elegant design, and can be used with a variety of accessories, such as short circuit plate, identification strip, baffle, etc.
6. Wall style
Screws are used to connect wires, the insulation material is PA66(flame retardant grade: UL94, v-0), and the connectors are made of high quality conductive metal materials.
