Description

Board-to-Board Connector

Technical field

The utility model relates to a board-to-board connector, in particular to a board-to-board connector in which a socket and a plug can be firmly combined.

Background technique

In consumer electronic products, it is often necessary to electrically connect two parallel circuit boards. Based on this need, a board-to-board connector emerges as the times require. A board-to-board connector generally consists of a plug and a socket, and plug terminals and socket terminals are respectively arranged in the plug and the socket. One end of the plug terminal and the socket terminal are respectively in electrical contact with a printed circuit board, and the other ends are electrically connected with each other, so as to realize the electrical connection between the two parallel circuit boards.

However, with the miniaturization of consumer electronic products, board-to-board connectors are also becoming more miniaturized. Therefore, board-to-board connectors need to continuously reduce the amount of mating between plugs and sockets, and also need to correspond to closely arranged socket terminals. With the plug terminal, there is a certain difficulty in the mutual fastening combination between the plug and the socket. Most of the existing board-to-board connectors change the terminal structure to cooperate with the relevant engaging parts set on the socket and the plug insulation body to achieve a stable combination of the socket and the plug, but after a period of time, the terminals are prone to yield and deformation The phenomenon, which affects the stable combination between the plug and the socket, and then leads to poor electrical connection between the plug and the socket.

Utility model content

The purpose of the utility model is to provide a board-to-board connector aiming at the defects and deficiencies of the prior art. The socket and the plug of the board-to-board connector can be firmly embedded and combined to ensure good electrical contact.

To achieve the above purpose, the board-to-board connector of the present invention includes a socket and a plug. The socket has a socket body and a plurality of female terminals. The socket body has a base plate, two first side walls protruding upward along two sides of the base plate, and two second side walls protruding upward along two ends of the base plate. Several female terminals are fixed on the first side wall. The base plate, the two first side walls and the two second side walls enclose a receiving cavity. The plug has a plug body and several male terminals accommodated in the plug body. The plug body has a bottom wall, and several male terminals are fixed on opposite sides of the bottom wall. A socket locking terminal is held on the second side wall of the socket, and the socket locking terminal has a first holding part, the first holding part is fixed on the second side wall of the socket body, and the middle part of the upper end of the first holding part extends upwards After being bent, it extends downwards to form an elastic part, and the elastic part extends into the receiving cavity. Two ends of the plug body hold a plug clamping terminal, and the plug clamping terminal has a second holding portion fixed at both ends of the plug body and elastically pressing against the elastic portion of the socket clamping terminal.

As mentioned above, the second holding portion of the plug locking terminal pushes against the elastic portion of the socket locking terminal. The elastic deformation occurs due to the pressure of the board-to-board connector, so that the second holding part and the elastic part are in close contact, so that the plug and the socket of the board-to-board connector of the utility model are firmly inserted and inserted, ensuring good electrical contact.
