Wafer connectors typically refer to connector bases (chip sockets), generally assembled from metal and plastic components. They are commonly used on PCB boards and assembled with wires and terminals. Unlike conduits that only consist of plastic components (some with iron shells), they are assembled with wires and terminals. Wafer socket connectors consist of fixed-end electrical connectors, namely female contacts (referred to as sockets), and free-end electrical connectors, namely male contacts (referred to as plugs). Sockets are fixed onto electrical components (some are also soldered) via their square (circular) disks, while plugs typically connect to cables and are secured to sockets through connecting nuts. Their function is to serve as communication bridges between circuits, allowing electric current to flow and enabling circuits to achieve the desired effects. Wafer connectors possess strong compatibility and are widely used in systems such as our TVs, DVDs, car DVDs, mobile phones, laptops, MIDs, digital cameras, fax machines, printers, amplifiers, speakers, and video doorbells.
