What is a wire-to-board connector

Posted by sere on November 30th, 2020

The so-called wire-to-board connector is the connector that connects the wires and the circuit board. The function of the connector is mainly to transmit power and signals. Therefore, the wire-to-board connector can be said to be the ancestor of all links, depending on various uses and requirements. , There are countless types of wire-to-board, but in the information industry, most of them are distinguished by the distance between the pins and the transmitted current and voltage.

The biggest difference between a wire-to-board connector and a wire-to-wire connector is a wafer. The wire-to-board connector is welded to the circuit board by the socket connection wire, which plays a role of current flow.

The structure of the wire-to-board connector is very simple: place the electrodes (contacts) in the shell (plastic shell). There are two types of contacts: stick or chip "plug" and "socket". Squeeze the plug completely into the socket and cover it to achieve "matching". Generally, "the socket is connected to the wire" and the plug is connected to the substrate" but this can be reversed depending on the usage. The connection of wires and contacts is generally achieved using "pressure bonding" technology, such as crimp terminals. You can also use "pressure welding" to connect wires and contacts. Pressure welding technology is used for low current connection "by simply connecting insulated wires to contacts" allowing full connection. Although this method is convenient, the durability may be reduced. The above two technologies can avoid overheating caused by soldering technology and protect the connection from damage. In addition, the "airtight connection area will not be exposed to the air" to keep the connection stable.
