Terminal blocks are electronic components used for circuit connection, also known as terminal blocks, electrical connectors, etc. It is a combination of multiple terminals. Terminals are accessory products used to realize electrical connection, and belong to connectors in industry. What is the terminal block for?
Terminal blocks and terminal blocks are electronic components used for circuit connection, also known as terminal blocks, electrical connectors, etc.
How do terminal blocks connect terminals?
1. There are no special provisions on the installation direction, but the swing and impact in the moving direction of the contact shall be avoided as far as possible.
2. After the terminal block and mounting hole are machined, install them with screws to avoid looseness.
3. When the back connection socket is used, the back connection socket is installed by one key.
4. Please use 1~2mm thick panels. Please insert the back of the wiring side of the terminal into the machined mounting hole.
5. Press the ribbon part of the mounting metal part with a screwdriver until the side protrusion passes through the back of the panel.
6. After all the protrusions appear on the back, the installation is completed and the socket is fixed.
7. When disassembling, press the protrusion of the installation metal piece to the side of the socket, and at the same time, gently press the entire socket from the wiring side on the back to separate it from the panel. The terminal block is composed of a fixed terminal block (hereinafter referred to as the socket) and a free terminal block (hereinafter referred to as the plug). Some sockets are welded and fixed on electrical components through their square and round disks. Plug is generally connected by cable, and the connection between plug and socket is realized by connecting nut.
8. The terminal block consists of three basic units: housing, insulator and contact. Housing terminal housing refers to the housing of plugs and sockets, connecting nuts and tail accessories. The housing is used to protect the internal parts of the terminal board, such as insulators and contact pin sockets, from damage. The upper positioning keyway ensures the positioning of the plug and socket. The coupling nut is used to connect and disconnect the socket.
9. The tail is used to protect the terminal between the conductor and the contact body from damage and to fix the cable. The shell also has certain electromagnetic shielding function. Generally, aluminum alloy machining and cold extrusion are adopted for the shell, and steel shell is mainly used for glass sealing welding and high temperature resistant electrical terminal platform. The insulator consists of pin insulator and socket insulator. Interface sealing body, conductor sealing body, etc. The utility model is used to keep the pin socket at the set position, electrically insulate each contact body and each contact body from the shell, and seal the insulator and interface seal body to improve the environmental resistance of the electrical terminal platform. In order to adapt to the high temperature resistance, low temperature resistance and flame retardancy of products, the geometric dimensions of parts are stable and reliable.
10. Insulators are mostly molded from thermosetting plastics. The interface sealing body and the wire sealing body are formed by silicone rubber molding. Contact pin jack is the general name of contact, which is divided into welding type, crimping type and winding type. It is used to realize circuit connection. The pin jack is the key component of the terminal strip, which directly affects the reliability of the terminal strip. The sockets are mostly made of elastic copper alloy with good conductivity and silver and gold plated on the surface to achieve the purpose of low contact resistance and corrosion resistance.
