AI Technical Summary
Existing board-to-board connectors are prone to loosening and falling off during vibration, and the tightening force is insufficient, resulting in unstable connections.
The snap-fit terminals are elastically fixed and interference-fitted with the female connector. The spring is used to elastically fix the terminals to the female connector, and the fixing plate is used to interfere with the female connector, which increases the stability of the snap-fit terminals. At the same time, the connecting terminals and snap-fit terminals are kept in contact to prevent them from falling off.
This improves the connection strength between the male and female seats, preventing them from falling off due to vibration and enhancing the stability and reliability of the connection.

[0005] The locking plate-to-plate connector provided by the present application adopts the following technical scheme:
[0006] A locking plate-to-plate connector includes a male seat and a female seat. The male seat and the female seat are both provided with fixing terminals for connecting circuit boards. The male seat is provided with a mounting groove, and the female seat is inserted into the mounting groove. The male seat is provided with a plurality of connecting terminals, and the female seat is provided with a plurality of clamping terminals. The clamping terminals are clamped with the corresponding connecting terminals. The clamping terminal includes an integrally formed connecting piece. A plurality of spring pieces for connecting the female seat are integrally arranged on the connecting piece. One end of the spring piece is integrally provided with a clamping piece. Adjacent two clamping pieces are arranged close to each other and cooperatively form a clamping cavity for clamping the connecting terminal. A fixing piece is integrally arranged on the side of the spring piece away from the connecting piece. The fixing piece extends into the female seat and is in interference fit with the female seat.
[0007] By adopting the above technical scheme, the clamping terminal is elastically fixed with the female seat through the spring piece, and is further fixed with the female seat through the interference fit of the fixing piece and the female seat, so as to avoid the clamping terminal from falling off after the female seat is shaken.
[0008] At the same time, the connecting terminal extends into the clamping cavity, and its two sides abut against the clamping pieces. In this way, the clamping of the connecting terminal and the clamping terminal is achieved. In addition, when the male seat is shaken, the clamping terminal can always abut against the connecting terminal, so as to avoid the disconnection of the clamping terminal and the connecting terminal as much as possible, and to increase the connection firmness between the male seat and the female seat.

[0015] Optionally, the side of the clamping sheet close to the connecting terminal is integrally provided with a clamping bubble point, and the clamping bubble point abuts against the side wall of the connecting terminal.
[0016] By adopting the technical scheme, the clamping bubble point abuts against the side wall of the connecting terminal, pushes the clamping sheet away from the connecting terminal, and makes the clamping sheet deform, so as to improve the connection and fastening of the clamping sheet and the connecting terminal.
[0017] Optionally, the clamping groove is provided with a top block on the opposite side wall at the two sides of the clamping sheet, and the top block abuts against the clamping sheet.
[0018] By adopting the technical scheme, the clamping sheet deforms after being installed in place, the top block is used to limit the curvature of the deformed and bent clamping sheet, and the relative distance of the two clamping sheets after deformation is avoided to be too large.
