Introduction to the uses of several common connectors

Concentric connector Concentric connectors are small plug and socket connectors that have a small volume and also serve as switches Concentric connectors are suitable for low-frequency circuits and are commonly used for wiring headphones, microphones, and external power supplies. Linear connector The number of leads in a linear connector is generally less than tens, suitable for circuit connections between printed circuit boards and components in equipment. Printed circuit connectors Printed circuit connectors are mainly used to connect printed circuit boards in electrical or electronic equipment. Ribbon cable connector The socket of the ribbon cable connector is directly soldered onto the printed circuit board, and the plug and ribbon cable are connected by puncture crimping, which can be completed in one go. The contact is reliable, easy to use, and suitable for connecting instrument circuits. Circular connector The plugs and sockets of circular connectors mostly use threaded connections, and their wiring terminals can range from two to hundreds, with the characteristics of small size and high reliability, which can meet the needs of cable connections between electronic devices. Rectangular connector The plugs and sockets in rectangular connectors are connected by threaded guide rods and have locking devices, mainly used for electrical connections of electronic devices, intelligent instruments and electronic control equipment. Water pressure resistant sealing connector This type of connector is mostly a circular connector, suitable for circuit connections working in water or harsh environmental conditions. RF Connector RF coaxial connector is a small threaded locking connector with the characteristics of small volume, light weight, and easy use, suitable for use in wireless equipment Used for connecting RF cables in high-frequency circuits of electronic instruments. Its operating frequency is generally as high as 500MHz.
