Embodiment
In order to save the inside electric appliance arrangement space, improve layout density, the utility model embodiment provides a kind of plate interconnection structure and a kind of electric equipment.In technical solutions of the utility model, platelet is inserted in the connecting pin of a plurality of power devices and the gap between function element, arrange vertical with mainboard, a plurality of connecting portions of platelet and the corresponding connection of the connecting pin of a plurality of power devices, this layout type takes full advantage of the intrinsic gap of inside electric appliance, greatly save the arrangement space of inside electric appliance, improved layout density.For making the purpose of this utility model, technical scheme and advantage clearer, by the following examples the utility model is described in further detail.
As shown in Figure 2, Figure 3 and Figure 4, the plate interconnection structure of the utility model embodiment comprises:
Function element 6, vertically be fixed in mainboard 5;
A plurality of power devices 7, be fixed in function element 6 one sides, the connecting pin of described a plurality of power devices 78 is vertical connect mainboard 5 and and function element 6 between there is gap;
The plate interconnection structure that the utility model proposes can be applicable in various types of electric equipment products.Mainboard 5 and platelet 3 are PCB(Printed Circuit Board, and printed circuit board (PCB) is called for short PCB).The type of power device 7 is not limit, and in the embodiment shown in Figure 2, power device 7 is power tube, the pin that connecting pin 8 is power device 7.The type of function element 6 is not limit, as long as vertically be fixed in mainboard 5, and have gap between the connecting pin 8 of a plurality of power device 7 and gets final product.It is worth mentioning that, " vertically " described in the utility model embodiment, not the angle between two parts strictly accurately is defined in to 90 degree, be construed as, near the certain error scope of angle 90 degree between two parts gets final product.Because the caloric value of power device 7 is larger, usually need to carry out auxiliary heat dissipation to it, therefore, function element 6 can be the radiator of auxiliary power device 7 heat radiations.
In technical solutions of the utility model, platelet 3 is inserted in the connecting pin 8 of a plurality of power devices 7 and the gap between function element 6, setting vertical with mainboard 5, a plurality of connecting portions of platelet 3 and the corresponding connection of the connecting pin 8 of a plurality of power devices 7, this layout type takes full advantage of the intrinsic gap of inside electric appliance, than prior art, between plate, interconnection does not need additionally to take arrangement space, therefore, greatly save the arrangement space of inside electric appliance, improved layout density.
