Background technique

In large-scale communication electronic products, a chassis is usually used to assemble circuit boards. The circuit board card is fixed to the chassis, and the board card needs to use a connector to realize electrical connection with other structures. Please refer to Figures 1 and 2, which show the two connection states of the connector. The connector usually includes a male connector 01 and a female connector 02. As shown in Figure 1, the mating surface of the male connector 01 and The distance between the mating surfaces of the female connector 02 is zero, which is the ideal state of the connector connection, which is called the connector full mating; however, as shown in Figure 2, due to the installation tolerances, it is difficult to achieve the connector full mating , Then there is a certain distance M (M>0) between the mating surface of the male connector 01 and the mating surface of the female connector 02, and the connector is not fully matched. The above M value affects the signal transmission quality of the connector. In order to make the connector have a better signal transmission effect, the smaller the above M value, the better. The way the board is installed in the chassis has a more important influence on the above-mentioned M value.

The frame 03 and the circuit board assembly 04 form a board, and the board passes The board card buckle assembly 05 is installed in the chassis 06 of the electronic device. In this solution, the board card buckle assembly 05 has poor compatibility with installation tolerances. The card head and the side wall of the chassis 06 are likely to interfere with each other, causing the board The card cannot be installed in the chassis, or the connection effect of the connector is poor, and the electrical connection reliability of the electronic device is poor. Please refer to FIG. 4, which shows a partial structural diagram of another electronic device. In the prior art, screws 07 can also be used to fix the card board and the chassis 06. This method not only requires additional screws 07, but also has many accessories. Reduce the layout density of the board of the electronic device and reduce the integration of the electronic device. In addition, the installation and disassembly process is more complicated; or in the prior art, the board and the chassis can be fixedly installed by using a power-assisted buckle, but additional assistance is provided The buckle will reduce the layout density of the board and reduce the integration of electronic equipment.

Summary of the invention

This application provides a buckle assembly, a board card, and an electronic device.

One end of the buckle has a chuck, and the buckle also has an operating part for driving the chuck to move relative to the fixing seat along a first direction toward the direction of the chuck; specifically, the first direction refers to When the buckle assembly is in the non-working state, the extension direction of the buckle. The above-mentioned non-working state refers to the reset state of the buckle component, that is, the state where the buckle of the buckle component is not under control force. Therefore, when the buckle assembly is used for installation, even if there is interference between the bayonet and the bayonet matched with the bayonet, the bayonet can be inserted into the bayonet by controlling the operating part to move the bayonet in the first direction.
