The connection form of the electrical connector is classified as follows:

1.Line-to-line connection

The wire-to-wire connection also includes wire-to-cable or cable-to-cable form, which is characterized by a permanent connection of two single-wire individual or two wires in the two cables. These permanent connections are more common in fixed-connection midline-to-wire connections as well as IDC connections. Curved connections are common in discontinuous wire connectors, and IDC is often used to dominate cable connectors because of its superiority in wire-related and wire harness end processing. The wire-to-wire has a variety of geometrical plastic supports Such as right-angle and round-shaped plastic parts of the body, there are many different shapes of the combination of plastic parts and metal shield shell, mainly in the military to be applied.

2. Board-to-board connection.

Two types of board-to-board connectors have been mentioned earlier, one is a monolithic connector or a card edge, and the other is a two-piece connector. The first board-to-board electrical connector is placed on the edge of the circuit board, so its development will eventually become a two-piece connector, because the printed circuit board technical performance and its size is growing, when the board size increases, The result will lead to the increase of the capacity of the electrical connector, thus increasing the number of terminals, the connector insertion force increases, the circuit board printed circuit capacity will lead to excessive line density, monolithic connector is difficult to meet its requirements, Which will eventually develop into a two-piece connector.

3. Line or cable-to-board connection.

Online connection to the board, half of the connector is connected with the line or cable, but also with the printed circuit board connected to the same line connection, the board is also the same connection, but need to press or weld two electrical connector, many Card-type connector is still in use, the terminal with the interface for separable connectivity, line-to-line connector is similar, they are from the same factory. The wire-to-board connector also has many other uses, the direction of its development is cable-to-board connectors, or cable assembly using the advantages of the aforementioned IDC.

The above is a brief introduction to several types of connection, to learn more about the contents of the electrical connector, please pay attention to kingsignal official website.
