Embodiment
Embodiment 1
Shown in Fig. 2 A and Fig. 2 B, the fixture 2 that auxiliary circuit board of the present utility model is used is to be made by plastics or metal, it is to have in the portion that sets firmly 20 of perforate 200 one to be formed with a joint portion 21, this joint portion 21 can set firmly portion 20 with respect to this, and to produce elasticity moving partially, and be formed with a fork prominent 210 on the surface of this joint portion 21, also be formed with a press section 22 on the top of this joint portion 21, simultaneously, this sets firmly and is formed with one in the portion 20 at interval to stopper 23 that should joint portion 21, formation one guide groove 24 between this stopper 23 and this joint portion 21.
The fixture 2 that Fig. 3 A and Fig. 3 B explanation uses auxiliary circuit board of the present utility model to use is fixed on user mode figure on the main circuit board with auxiliary circuit board.As shown in Figure 3A, be provided with at least one electric connector 31a at a main circuit board 31, one auxiliary circuit board 32 has at least one electric connecting terminal 32a with respect to this electric connector 31a, the electric connecting terminal 32a of this auxiliary circuit board 32 can be electrically connected to the electric connector 31a of this main circuit board 31, and is formed with a perforation 32b on this auxiliary circuit board 32.
It is to use the locking part 25 as screw or expandable nail to pass this perforate that sets firmly portion 20 200 and lock this main circuit board 31 that this fixture 2 is established with the group of main circuit board 31, and this fixture is located on the main circuit board 31 for 2 groups.Will be appreciated that though use this to set firmly the perforate 200 and the locking part 25 of portion 20 in the present embodiment, the mode that other fixture 2 combines with main circuit board 31 also can be suitable for, this is to have in the affiliated technical field to know the easily variation that reaches of full of beard of the knowledgeable usually.
