[0032] The technical scheme of the utility model adopts the two opposite end faces of the fixed main body 1, which are set as the first abutting face 11 and the second abutting face 12, and the first abutting face 11 and the second abutting face 12 are in abutting contact with one of the first printed board 30 and the second printed board 40 respectively, so that the first printed board 30 and the second printed board 40 are spaced apart, which meets the stacking design demand of the first printed board 30 and the second printed board 40, and the fixed main body 1 is a structural member that can be applied to various modules, which can save the time for stacking the first printed board 30 and the second printed board 40.
[0033] Further, please refer to Figure 1The first abutting surface 11 and the second abutting surface 12 are arranged in parallel. It can be understood that the first printed board 30 and the second printed board 40 are stacked in space, and the fixed body 1 is arranged between the first printed board 30 and the second printed board 40, so as to facilitate the circuit test of the first printed board 30 and the second printed board 40. However, it can be understood that the first printed board 30 and the second printed board 40 extend in a plane, so as to avoid the interference between the first printed board 30 and the second printed board 40 regardless of the area of the first printed board 30 and the second printed board 40. Therefore, the first abutting surface 11 and the second abutting surface 12 are arranged in parallel, and the printed board at the first abutting surface 11 and the second printed board 40 at the second abutting surface 12 are also arranged in parallel. Therefore, the first printed board 30 and the second printed board 40 do not interfere with each other in space regardless of the area of the first printed board 30 and the second printed board 40, thereby meeting the stacking requirement and facilitating the circuit test.
[0034] In addition, the fixed body 1 is transparent. It can be understood that, in the circuit test, in order to observe the first printed board 30 and the second printed board 40, the fixed body 1 is transparent, thereby facilitating observation in the test.
[0035] In addition, the material of the fixed body 1 includes acrylic plastic material. It can be understood that, in the circuit test, the first printed board 30 and the second printed board 40 generate a certain amount of heat, and in order to avoid danger, the first printed board 30 and the second printed board 40 need to be cooled.
