[accompanying drawing explanation]
Fig. 1 is the utility model structural representation.
[embodiment]
The explanation of following embodiment is graphic with reference to what add, can in order to the specific embodiment implemented in order to illustrate the present invention.The direction term that the present invention mentions, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " side " etc., be only the direction with reference to annexed drawings.Therefore, the direction term of use is in order to illustrate and to understand the present invention, and is not used to limit the present invention.In the drawings, the unit of structural similarity represents with identical label.
As shown in Figure 1, Combined circuit board of the present utility model, comprises circuit board group and combination unit; Described circuit board group comprises first circuit board 1 and second circuit board 2; Described combination unit comprises symmetrical semi-enclosed upper ledge 4 and underframe, and one end that described upper ledge 4 and the underframe left and right sides do not connect is openend, and the other end is link; Described upper ledge 4 and underframe openend close mutually, described upper ledge 4 and underframe link chain connection, so that described upper ledge 4 and underframe openend can do opening and closing movement with its link; The front surface of described underframe dual-side is respectively arranged with two groups of positioning cylinders, and being wherein positioned at inside described underframe is the first positioning cylinder group, and being positioned at outside described underframe is the second positioning cylinder group; Preferably, described first positioning cylinder group and the second positioning cylinder group drain into few three positioning cylinders by two respectively and rearrange along described underframe length direction; The bottom surface of described upper ledge 4 dual-side is provided with the first corresponding with described first positioning cylinder group and the second positioning cylinder group quantity and position respectively holddown groove and the second holddown groove; Preferably, offer shrinkage pool bottom described first holddown groove and the second holddown groove, described shrinkage pool diameter is slightly larger than described positioning cylinder diameter, and described positioning cylinder top is inserted in described shrinkage pool; Described first circuit board 1 dual-side offers first positioning through hole corresponding with described first positioning cylinder group, and described second circuit board 2 dual-side offers second positioning through hole corresponding with described second positioning cylinder group.
Because circuit board has thickness, described upper ledge 4 cannot be completely closed with underframe, needs to offer the height rectangular through-hole suitable with circuit board thickness in described upper ledge 4 side, when described upper ledge 4 closes with underframe, circuit board just in time as in rectangular through-hole, limits circuit board position further; Preferably, when described upper ledge 4 closes with underframe, the edge of described rectangular through-hole and circuit board are fitted, and hard edge can cause damage to circuit board, in order to further protective circuit plate, arrange rubber strip in described rectangular through-hole outer; Described rubber strip is adhered to described rectangular through-hole outer, and described rubber strip can play good cushioning effect to circuit board by active force.
In order to further fixing circuit board, described upper ledge 4 and underframe are connected by hasp, and described hasp is separately positioned on the both sides of the openend of described upper ledge 4 and underframe; And for example, described upper ledge 4 and underframe also connect by screw; Further, arrange screw at the openend of described underframe, the openend of described upper ledge 4 arranges becket, and described becket is corresponding with described screw, then enters in screw with screw through described becket, fixing by described upper ledge 4 and underframe.
Described circuit board group comprises tertiary circuit plate 3, and described tertiary circuit plate 3 both sides are respectively arranged with the 3rd positioning through hole, and described 3rd positioning through hole one is placed in described second positioning cylinder group.
During use, upper ledge 4 described in Unscrew, by on the first positioning through hole cover to described first positioning cylinder group of described first circuit board 1, the second positioning through hole on described second circuit board 2 and tertiary circuit plate 3 and the 3rd positioning through hole are overlapped the both sides to described second positioning cylinder group respectively, then rotate described upper ledge 4 to close to underframe described in it, now, the top of described first positioning cylinder group and the second positioning cylinder group is inserted in the shrinkage pool bottom described first holddown groove and the second holddown groove respectively, finally the hasp being positioned at described upper ledge 4 and underframe openend is fastened, so, by multiple circuit board composition, effectively improve installation and removal efficiency.
Adopt such scheme, Combined circuit board of the present utility model, by aggregates for polylith circuit board reasonable combination, the advantage with efficient dismounting is installed compared to independently circuit board, saves disassembly and assembly time, enhance productivity.
