Abstract

The invention discloses a printed circuit board (PCB) based network connection structure. A first circuit and a second circuit are arranged on a PCB and are separated from each other, the network connection structure is characterized in that the first circuit comprises a first network and a second network, and the first network and the second network are electrically connected and are electrically conducted through a short-circuit path. In the network connection structure, the short-circuit path is arranged between the isolated networks, and bill of material (BOM) cost is saved; meanwhile, since the short-circuit path can be arranged at an arbitrary layer of the PCB, the design flexibility also can be enhanced; and with the arrangement of the short-circuit path, a complicated isolation area pattern is not needed to be drawn on the PCB, and the design difficulty and the error probability can be simultaneously and substantially reduced.

Detailed description of the invention

In order to make those skilled in the art be more fully understood that the technical scheme in the present invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of protection of the invention.

Comparative example one:

Shown in ginseng Fig. 1 a～Fig. 1 d, PCB 10 is provided with some devices, at least include the first device 21 and the second device 22, isolation area is generally included between first device 21 and the second device 22, isolation area is isolated by first line 30 and former network, and first line 30 is connected with the first device 21 and the second device 22 respectively. Generally, isolation area is irregularly shaped, and owing to isolation area figure is irregular, first line 30 design is got up comparatively laborious, needs to revise the design of this subnetwork during change cabling design simultaneously.

Compare two:

Shown in ginseng Fig. 2 a～Fig. 2 c, PCB 10 is provided with some devices, at least include the first device 21 and the second device 22, isolation area is generally included between first device 21 and the second device 22, isolation area is isolated with former network by first network 31 and the second network 32, it is electrically connected by resistance 33 between first network 31 and the second network 32, to form first line 30, wherein, this resistance 33 is 0ohm resistance, increase an extra 0ohm resistance as wire jumper, but this 0ohm resistance need to be arranged at upper surface or the lower surface of PCB 10, need to take the space, top layer of PCB.
