Corresponding second fixing member 42 , at least one positioning post 43 protruding upward from the base wall 221 , a positioning hole 44 penetrating the second circuit board 31 and corresponding to the positioning post 43 , a through hole 221 and a first fixing The member 41 is provided with a fixed through hole 45, and a through hole 46 penetrating through the second circuit board 31 and for the second fixing member 42 to be fastened. More specifically, the first fixing member 41 is disposed on the base wall 221 of the insulative housing 22 and has an end 411 exposed on the base wall 221. In this embodiment, the first fixing member 41 is a stud and is disposed. The second threaded hole is fixed to the through hole 45 by heat fusion. The second fixing member 42 is a screw and is provided with an external thread. The number of the positioning post 43 and the positioning hole 44 is two, and is disposed on opposite sides of the first fixing member 41. And between the two side walls 222.

Referring to FIG. 2, FIG. 5 and FIG. 6, when the second connecting device 3 is to be docked with the first connecting device 2, the abutting portion 311 of the second circuit board 31 is first The mating direction D is disposed in the docking space 226. Specifically, when the abutting portion 311 passes between the two hook portions 223, the guiding portion 223 is guided by the top inclined surface 2231 of the hook portion 223, and the two side walls 222 are elastically elastically deformable, so that the hook portion 223 can be subjected to the abutting portion. The 311 is pushed forward and the elastic phase is located between the side walls 222, which is located between the side walls 222, that is, in the docking space 226, and is fastened by the bottom surface 2232 of the hook portion 223 to the upper surface of the second circuit board 31. The portion 311 is restricted between the hook portion 223 and the base wall 221, and the lower surface of the second circuit board 31 abuts against the first fixing member 41, and is respectively inserted into the two positioning posts 43 through the two positioning holes 44, so that each The pad 32 is in contact with the corresponding elastic contact portion 231 of each terminal 23 (see also FIG. 7). Finally, the second fixing member 42 is inserted through the through hole 46 and then screwed to the first fixing member 41 to fix the second circuit board 31 and the insulating body 22.

When the second connecting device 3 is to be separated from the first connecting device 2, the second fixing member 42 is removed first, and then the second circuit board 31 is removed in the opposite direction to the docking direction D to be separated.

The second connecting device 3 is connected to the first connecting device 2 by using a plurality of guiding pads 32 directly disposed on the second circuit board 31. Generally, the connector of the second circuit board and the connector of the first circuit board are required. Electrical connection saves costs and is easy to dock, which in turn increases market competitiveness.

Referring to Figures 8, 9, and 10, another embodiment of the insulative housing 22 of the present embodiment is shown. The second hook portion 223 (see FIG. 2) in which the ends of the side walls 222 are oppositely protruded in this embodiment can still be implemented.

More specifically, when the first circuit board 21 and the second circuit board 31 When the assembly height has to be adjusted or the thickness of the first circuit board 21 and the second circuit board 31 are different, the first fixing member 41 having different protruding heights can be used for adjustment, and the insulating body 22 is not required to be re-opened. That is, when the end 411 of the first fixing member 41 protrudes from the base wall 221 of the insulative housing 22, the end 411 of the first fixing member 41 can provide contact with the second circuit board 31, using the end of the first fixing member 41. The difference in height of the 411 is adapted to the second circuit board 31 of different board thicknesses. As shown in FIG. 9, FIG. 10, FIG. 12, and FIG. 13, when the thickness of the second circuit board 31 is different, the same assembly height can be maintained, and FIG. 8 and FIG. 11 are compared, when the second circuit board 31 is thick. (As shown in FIG. 9), the protrusion height of the first fixing member 41 is low (as shown in FIG. 8), and when the second circuit board 31 is thin (as shown in FIG. 12), the protrusion of the first fixing member 41 is convex. The height is higher (as shown in FIG. 11), and thus the second board 31 of different board thickness can be applied by using the first fixing members 41 of different protruding heights. Further, as shown in FIGS. 12 and 15, the same second circuit board 31 can be adjusted by using the first fixing members 41 having different projecting heights in order to accommodate different assembly heights. Comparing FIG. 11 with FIG. 14, in FIG. 11, the protruding height of the first fixing member 41 is higher, and the second circuit board 31 can be raised (as shown in FIG. 12 and FIG. 13). In FIG. 14, the first The height of the protrusion of the fixing member 41 is relatively low (substantially flush with the base wall 221 of the insulative housing 22), so that the assembly height of the second circuit board 31 is low (as shown in FIGS. 15 and 16), and the elastic contact portion The 231 has elasticity. As shown in FIGS. 14, 15, and 16, the second circuit board 31 can electrically connect the pad 32 (see FIG. 5) to the elastic contact portion 231 of the terminal 23 within a certain height range.

In summary, at least one positioning hole 44 can be directly visually positioned The number of the positioning posts 43 corresponding to the positioning holes 44 can prevent the connector from being damaged due to the inability to be positioned during the docking; and the first circuit board 21 and the second circuit can be adjusted by using the first fixing member 41 having an appropriate protruding height. The assembly height between the plates 31 makes it possible to achieve the object of the present invention.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are still It is within the scope of the patent of the present invention.
