Terminals - PC Pin, Single Post Connectors

PC pin, single post connectors are terminals that are used to connect an individual wire to a printed circuit board. They\'re typically found on variety of electronic products, from consumer electronics to computers. This peculiar type of connector has been widely used through the decades, since its introduction back in the 1970s.

PC pins are formed from galvanized steel and designed for high reliability. The pins feature a unique geometry that gives them a non-uniform shape, with the base varying in width. This design allows them to be inserted into the plated through holes of the printed circuit board much easier than other connector types. Moreover, the unique shape of the pins ensures greater stability in comparison to generic terminals.

A single post connector has a single pin, which is inserted into a pre-drilled hole on the PCB. The pins are soldered to the board, making the connection secure. They come in a variety of shapes and sizes, to meet the needs of various applications. One of the advantages of PC pins is that no special tools are required for insertion, so they can be used in applications where easy assembly is required.

The working principle of PC pins is fairly simple. When the pin is inserted into the plated through hole, its shape causes a compression of the plated copper along the walls of the hole. This compression compresses the plated copper and creates a contact between the pin and the PCB. When the pin is soldered, the contact is secure and the connection is strong.

Since its inception, PC pin, single post connectors have become the go-to solution for applications that require easy and reliable connections. They continue to be widely used in the consumer electronics and computing industries and are set to dominate the market in the foreseeable future.
