Fig. 2 is the structural representation of the embodiment of pcb board that uses in the utility model electronic product.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

At first, brief description design philosophy of the present utility model: in the electronic products such as player, set-top box, game machine, usually all dispose the analog modules such as video, sound, the circuit module such as the CPU on this class circuit module and pcb board, memory is compared, and volume is larger.If the circuit module that these volumes are larger and other circuit module integrated setting on mainboard, will occupy larger mainboard area, and be not easy to come flexibly layout on mainboard.And, because the present mainboard of electronic product adopts the more much higher laminate of cost mostly, circuit module as larger in fruit volume is set directly on mainboard, needs to adopt the larger mainboard of area, reduce the utilance of other layers in the multilayer mainboard, improved the cost of pcb board.Given this, the utility model is considered whole pcb board is divided into two parts, and a part is used as mainboard, and another part adopts the low lamina of cost to use as subplate, can volume is large, the independent layout of circuit module that wiring is less is on subplate.

Please refer to Fig. 1, this Figure 1 shows that the structural representation of an embodiment of the utility model pcb board.

As shown in Figure 1, the pcb board of this embodiment includes mainboard 1 and subplate 2, and wherein, mainboard 1 can be lamina, can be also multi-layer sheet, and subplate 2 is lamina.Be provided with socket 11 on mainboard 1, be provided with plug 21 on subplate 2, mainboard 1 and subplate 2 are realized being electrically connected to the grafting of plug 21 by socket 11.

The pcb board of this embodiment is in being applied to electronic product the time, on the subplate 2 that can circuit module volume is large, that wiring is less arranges, remaining circuit module is arranged on mainboard 1, under the prerequisite that does not increase the wiring complexity, can simplify the layout of circuit module on pcb board, improve the utilance of pcb board.Concrete application can be with reference to shown in Figure 2 and following description to Fig. 2.

Socket 11 and the plug 21 on subplate 2 on mainboard 1 are not limited to shown in this embodiment, can be set to as required a plurality of.And mainboard 1 is not limited to the described structure of this embodiment with being electrically connected to of subplate 2, can also be plug to be set on mainboard 1, on subplate 2, socket to be set; Perhaps, mainboard 1 and subplate 2 are electrically connected to by winding displacement etc.

Please refer to Fig. 2, this Figure 2 shows that the structural representation of an embodiment of pcb board who uses in the utility model electronic product.The electronic product of this embodiment is network machine top box.

As shown in Figure 2, in network machine top box, the circuit module on its pcb board except CPU12 and other custom circuit modules, also includes analog module 22 and usb interface module 24.Wherein, analog module 22 is generally video, sound, component etc.

For improving layout flexibility and the cost of network machine top box pcb board, its pcb board is divided into the two large divisions, and a part is mainboard 1, and another part is subplate 2.Wherein, mainboard 1 is multi-layer sheet, and subplate 2 is lamina.Consider that analog module 22 and usb interface module 24 volumes are larger, but its number of signals is less, therefore, with these two circuit module layouts to subplate 2.Except being provided with CPU12, also be provided with two sockets on mainboard 1, i.e. socket 11 and socket 13, these two sockets are electrically connected to CPU12 respectively.Accordingly, be provided with the plug 21 that is electrically connected to analog module 22 and the plug 23 that is electrically connected to usb interface module 24 on subplate 2.And socket 11 is pegged graft with plug 21, and socket 13 is pegged graft with plug 23, thereby the analog module 22 on subplate 2 and usb interface module 24 are electrically connected to the CPU12 on mainboard 1 respectively, to carry out the transmission of data.

So, be arranged on by occupying the larger circuit module of volume on the subplate 2 of the low lamina of cost, other circuit modules are arranged on mainboard 1, have avoided the larger circuit module of volume to the taking of mainboard 1 area of the more much higher laminate of cost, and have reduced the pcb board cost; And, be convenient to carry out separately the layout of circuit module on mainboard 1 and subplate 2, improved layout convenience and flexibility.In addition, due to the signal transmssion line negligible amounts of analog module 22 and usb interface module 24, not increasing wiring between mainboard 1 and subplate 2, to realize the complexity that is electrically connected to, can not affect signal transmission quality yet.

Above-described embodiment, by the jigsaw structure, breaks the whole up into parts all circuit modules, can effectively improve the pcb board utilance, reduces the pcb board cost, and then improves cost and the market competitiveness of the electronic product that uses this pcb board formation.

Above embodiment is only in order to the technical solution of the utility model to be described, but not is limited; Although with reference to previous embodiment, the utility model is had been described in detail, for the person of ordinary skill of the art, still can modify to the technical scheme that previous embodiment is put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model technical scheme required for protection.
