Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-Figure 5The utility model provides the following technical solution: a blank circuit board that is easy to cut, comprising a circuit board body 1, an electronic component 2 is arranged on the top of the circuit board body 1, and a dividing structure 3 is arranged on both sides of the circuit board body 1;

[0026] Preferably: the dividing structure 3 includes a first connecting piece 301, a second connecting piece 302, an equal portion of convex block 303 and an equal portion of concave groove 304, the first connecting piece 301 and the second connecting piece 302 are arranged on both sides of the circuit board body 1, one end of the first connecting piece 301 is arranged with an equal portion of concave groove 304, and one end of the second connecting piece 302 is arranged with an equal portion of convex block 303, the first connecting piece 301, the second connecting piece 302, the equal portion of convex block 303 and the equal portion of convex block 303 are made of plastic material, and the hardness of the connection between the first connecting piece 301, the second connecting piece 302, the equal portion of convex block 303, the equal portion of concave groove 304 and the circuit board body 1 is the same.
[0027] During specific use, the equal-divided concave grooves 304 and the equal-divided convex blocks 303 on both sides of the circuit board body 1 are separated under the action of pressure. At the same time, the hardness of the first connecting piece 301 and the second connecting piece 302 connected to the circuit board body 1 is the same as the hardness of the connection between the equal-divided concave grooves 304 and the equal-divided convex blocks 303. At this time, the first connecting piece 301 and the second connecting piece 302 are applied with the same force to separate from the circuit board body 1. In this way, due to the overall regular shape of the dividing structure 3, the outer edge of the circuit board body 1 can be separated neatly, and there will be no uneven edges.
[0028] Preferably, the auxiliary structure 7 comprises a transverse auxiliary line 701, a longitudinal auxiliary line 702 and an outer layer strip 703, the transverse auxiliary line 701 and the longitudinal auxiliary line 702 are arranged on both sides of the connection hole 6, the outer layer strip 703 is arranged on the outer side of the transverse auxiliary line 701 and the longitudinal auxiliary line 702, and the material of the outer layer strip 703 is film paper material.
[0029] During specific use, when the staff is wiring the circuit board body 1, the outer strip 703 on the back of the circuit board body 1 can be removed, and then wiring can be performed according to the pre-set distribution of the horizontal auxiliary lines 701 and the vertical auxiliary lines 702. This can provide standard wiring conditions for non-professionals and increase the scope of use of the circuit board body 1.
[0030] It should be noted that the depth of the interconnection between the equal-divided recessed groove 304 and the equal-divided convex contact block 303 is equal to half of the inner length of the equal-divided recessed groove 304 and the equal-divided convex contact block 303, thereby reducing the strength of the connection between different sections of the circuit board body 1.
[0031] Working principle: When using the blank circuit board that is easy to cut, first place the circuit board body 1 on the workbench of the stamping equipment prepared in advance. At this time, the punching device of the stamping equipment punches the connection seam of the circuit board body 1. At this time, the longitudinal connection dots 4 and the connecting strips 5 connected between different circuit board bodies 1 are broken and separated. At this time, the front and rear ends of the circuit board body 1 are separated, and then the equal-divided concave connection grooves 304 and the equal-divided convex connection blocks 303 on both sides of the circuit board body 1 are separated under the action of pressure. At the same time, the hardness of the first connecting piece 301 and the second connecting piece 302 connected to the circuit board body 1 and the equal-divided concave connection grooves 304 and the equal-divided convex connection blocks 303 are separated. The bump block 303 has the same hardness at the connection. At this time, the first connecting piece 301 and the second connecting piece 302 can be separated from the circuit board body 1 by applying the same force. In this way, due to the overall regular shape of the dividing structure 3, the outer edge of the circuit board body 1 can be separated neatly without uneven edges. When the staff performs wiring processing on the circuit board body 1, the outer strip 703 on the back of the circuit board body 1 can be removed, and then wiring can be performed according to the pre-set distribution of the horizontal auxiliary lines 701 and the vertical auxiliary lines 702. This can provide standard wiring conditions for non-professionals and increase the scope of use of the circuit board body 1.
