Embodiment Construction
[0018] Examples of electronic equipment boxes are figure 1 As shown: including the box body, the printed board 2 and the back plate, the box body includes the upper box plate 3, the lower box plate and a plurality of rails 4 with lengths extending along the front and rear directions arranged on the inner surfaces of the upper and lower box plates, Among them, two rails arranged up and down opposite each other form a pair, and the opposite sides of each pair of rails are provided with guide rails whose guiding direction extends along the front and rear directions. on the track groove. There are two power-assisted plug-in components for printed boards between the box and each printed board, and the two power-assisted plug-in components for printed boards are arranged opposite to each other. The spring 5 at the front end and the booster block 6 that is rotatably arranged on the front end face of the printed board, the rotation axis of the spring is positioned at the rear side of...

The invention relates to a printed circuit board power-assisted plug-pull assembly and an electronic equipment box using the same. The printed circuit board power-assisted plug-pull assembly comprises a spring and a power-assisted block used for being respectively and rotatably arranged on a corresponding box body and a corresponding printed circuit board in use. The rotating axes of the spring and the power-assisted block are arranged in an extending manner in the left-and-right direction. The spring comprises left and right elastic arms which have the amount of elastic deformation in a direction perpendicular to the rotating axis of the spring, a connecting arm is connected between the left and right elastic arms, and the left and right elastic arms and the connecting arm form a U-shaped structure. The power-assisted block is provided with a clamping slot for clamping the connecting arm. When in use, the maximum distance from the rotating axis of the spring to the clamping slot is greater than the free-state length of the left and right elastic arms, and the minimum distance from the rotating axis of the spring to the clamping slot is smaller than the free-state length of the left and right elastic arms. The invention provides a simple-structure printed circuit board power-assisted plug-pull assembly and an electronic equipment box using the same.
Description
technical field [0001] The invention relates to a printed board auxiliary plug-in assembly and an electronic equipment box using the plug-in assembly. Background technique [0002] The current electronic equipment box includes a box body, the box body is provided with guide rails whose guiding direction extends along the front and rear directions, and the box body is provided with a backboard at the end of the guide rail's guiding stroke. When in use, the backboard is guided from front to back and assembled on the guide rail When it moves to the end of the guiding stroke of the guide rail, it is plugged and electrically connected with the backplane. This backplane assembly structure can cancel the signal and power interconnection lines at the rear end of the printed board. By arranging the signal and power interconnection lines on the back In the board, the wiring distance between printed boards can be effectively shortened, and the reliability of signal and power line conne...
