The flexible wire group 300 is placed in the storage groove 101. The end of the flexible wire group 300 away from the circuit main board 100 is fixed on the plug strip 200. The circuit main board 100 is electrically connected to the gold finger 201 through the flexible wire group 300.

[0040] A wire collection assembly is disposed in the storage slot 101, and the wire collection assembly is used to control and adjust the length of the flexible wire group 300 extending out of the storage slot 101;

[0041] A pair of grooves 102 are provided on one side of the circuit board 100 close to the plug strip 200. The two grooves 102 are respectively located at two ends of the circuit board 100 close to the plug strip 200. Connecting components 400 are provided in each of the grooves 102. The connecting components 400 are used to be detachably connected to the plug strip 200.

[0042] When the circuit board is plugged into the slot on the external device for installation, the circuit main board 100 and the plug-in strip 200 can be disassembled and separated by the connecting component 400, and the extended length of the soft wire group 300 can be increased by controlling the adjustment of the wire collection component. During installation, the circuit main board 100 and the plug-in strip 200 are separated, which can reduce the height of the entire circuit board along the depth direction of the external device slot, effectively reduce the obstruction of the line of sight of the circuit board during the installation process, reduce the risk of damage to the circuit board due to misalignment of the plug-in, improve the convenience of operation and the accuracy of observation, and make the installation process more flexible and convenient.

[0043] In order to facilitate the detachable connection between the circuit board 100 and the plug strip 200, a pair of symmetrically placed threaded holes 202 are provided on one side of the plug strip 200 close to the circuit board 100, and the threaded holes 202 correspond to the grooves 102 one by one;

[0044] The connecting assembly 400 includes a telescopic rod 401, which is fixed on the groove wall of the corresponding groove 102 away from the plug-in strip 200. The telescopic rod 401 is placed coaxially with the corresponding end threaded hole 202. The end of the telescopic rod 401 close to the plug-in strip 200 is rotatably clamped with a bolt 402 that is compatible with the threaded hole 202, and when the bolt 402 is fully screwed into the threaded hole 202, the telescopic rod 401 is in a state of maximum extension; by screwing the bolt 402 into or out of the threaded hole 202, a detachable connection between the circuit board 100 and the plug-in strip 200 is achieved.

[0051] In order to facilitate control and adjustment of the length of the flexible wire group 300 extending out of the storage slot 101, a strip-shaped slide slot 103 is provided on any side wall of the circuit main board 100;

[0052] The wire take-up assembly includes a pair of rollers 700 disposed in the storage slot 101, one of which is fixed in the storage slot 101, and the other is slidably connected in the storage slot 101, a sliding block 701 is slidably engaged in the slide slot 103, and the sliding block 701 is fixedly connected to the roller 700 slidably connected in the storage slot 101;
