Wire to board connectors are used on pcb boards to directly connect different data, signals or power through wires. A wire to board connector is a connector commonly used in electronic equipment to realize circuit connection and transmission.

First, the basic structure of the wire-to-board connector
A wire-to-board connector consists of two parts: a socket and a plug.
A receptacle is a part mounted on a circuit board to accept a plug into it.
The plug is the part that connects the wires and can be inserted into the socket to make the connection with the circuit board.
The electrical connection between the socket and the plug is realized through a metal contact piece.

Classification of wire-to-board connectors
Wire-to-board connectors can be divided into various types according to their structure and usage.
Common wire-to-board connectors include:
1. In-line connector: The socket and plug of the in-line connector are directly inserted into the socket in the circuit board, which is suitable for electronic equipment requiring compactness.
2. Elastic contact connector: The elastic contact connector is connected to the plug through the elastic contact piece, which can realize quick plug-in and reliable electrical connection.
3. Lead type connector: The lead type connector connects the socket and the plug through the lead wire, which is suitable for occasions where the wire connection is long or flexible wiring is required.
4. Spring-type connector: The spring-type connector fixes the plug on the socket through the spring, which can realize reliable connection and fixation.
5. Welded connector: The soldered connector fixes the socket and plug on the circuit board by welding, and is suitable for occasions that require high connection stability.

The utility model relates to a wire-to-board connector, which comprises a board-end connector and a wire-end connector. Båda sidorna av botten av kortkontakten är försedda med ett antal jämnt anordnade kontaktuttag. Den högra ändytan på kortändkontakten är försedd med en införingsport, och den övre ytan av kortändkontakten är försedd med två korthål. The end of the line-end connector is provided with a plug joint that cooperates with the plug interface, and the inside of the plug joint is provided with a conductive terminal. Two projections cooperating with the card holes are arranged on the side end surface of the plug joint. The plug connector of the line-end connector is plugged into the plug-in interface of the board-end connector and is fixed by mutual locking between the protrusion and the locking hole. The wire-to-board connector of the utility model has a simple structure, and after the board-end connector and the wire-end connector are plugged together, the bumps and the locking holes are engaged and fixed with each other. The retention force between the wire end connector and the board end connector is increased, and the structure is fixed. It can protect the use safety of the line-end connector and the board-end connector after mating, and ensure the signal transmission effect after docking.

A wire-to-board connector, the insulating base of the connector is provided with a receiving slot for placing and positioning preset wires. And one side of the insulating base body is formed with a joint that is docked with the external connector, and a plurality of contact terminals positioned around the joint are provided on the joint. And one end of each contact terminal is provided with a welding part passing through the insulating base body to the receiving wire groove and connected with the preset wire. It is characterized in that: the plurality of contact terminals are in the shape of a horizontal U shape, and the bottom of each contact terminal is provided with a welding part with a long distance and positioned on the inner surface of the wire receiving groove. And the contact terminal is also provided with a contact portion that is bent upward and reversely and surrounds the periphery of the joint, and one end of the contact portion is connected with the welding portion.
