As shown in fig. 1 to 4, the present invention provides a carrying fixture for increasing the stability of a printed circuit board by three-dimensional positioning, which includes a main body 10 and two positioning columns 20 and 30. The body 10 defines a recess 11. Each positioning post 20,30 is protruded from the main body 10 and is located at one side of the groove 11. The top of each positioning post 20,30 is provided with a convex block 21,31 and a positioning block 22,32, the positioning block 22,32 surrounds the outer side of the convex block 21,31, and a positioning groove 23,33 is formed between the inner side of the positioning block 22,32 and the outer side of the convex block 21, 31.
How the present invention provides a printed circuit board 100 with three-dimensional positioning effect will be further described with reference to the drawings.
Referring to fig. 5, fig. 5 is a top view of a pcb 100 positioned on the supporting fixture for improving the stability of the pcb by three-dimensional positioning according to the present invention. As shown in fig. 5, the pcb 100 is disposed in the recess 11, the bottom portions 111,121 of the two fixing pieces 110,120 are disposed on the surface of the pcb 100, and the top portions 112,122 of the two fixing pieces 110,120 are positioned in the two positioning slots 23, 33. More specifically, the top portions 112,122 of the fixing pieces 110,120 have shapes corresponding to the shapes of the positioning grooves 23,33, and the outer sides of the top portions 112,122 of the fixing pieces 110,120 abut against the inner sides of the positioning blocks 22, 32. The top 112,122 of each fixing piece 110,120 forms a through hole 1121,1221, each lug 21,31 is inserted through the through hole 1121,1221 of the top 112,122 of each fixing piece 110,120, the length of the through hole 1121,1221 of the top 112,122 of each fixing piece 110,120 is greater than the length of each lug 21,31, and the width of the through hole 1121,1221 of the top 112,122 of each fixing piece 110,120 is equal to the width of each lug 21, 31. The combination of the respective protrusions 21,31 and the respective positioning blocks 22,32 can provide a stable three-dimensional positioning effect for the tops 112,122 of the respective fixing pieces 110,120, prevent the respective fixing pieces 110,120 from moving in the X-axis direction and the Y-axis direction, and the respective fixing pieces 110,120 can further prevent the printed circuit board 100 from moving in the X-axis direction and the Y-axis direction in the recess 11.
