Abstract

The invention relates to a multilayer PCB (Printed Circuit Board) central distribution box. The multilayer PCB central distribution box comprises an insulated box body, a plurality of PCBs positioned inside the insulated box body and at least one pair of conductive pins; the plurality of PCBs are arranged in parallel and layer by layer, and the two adjacent layers of PCBs are insulated by insulating paper and connected by insulating screws; one end of each of the two conductive pins in every pair of conductive pins is connected to the different layer of PCB, and the other end extends out from the outermost PCB. A common PCB design in weak current is introduced to the multilayer PCB central distribution box, and the plurality of PCBs are applied to high-current wiring, so that high tidiness, high safety, high safety and minimum cost of wiring are achieved.

Description

Multi-layer PCB central power distribution box
Technical field
The invention belongs to the electric field of engineering machinery, particularly relate to and adopt multi-layer PCB circuit energising technology to carry out big current control, be specifically related to multi-layer PCB central power distribution box
Background technology
The engineering machinery field of present stage, electric aspect all will run into the very large big current up to about 30A, and large-current electric pneumatic control is greatly all adopt copper bar to carry out current delivery or single PCB scheme.Copper bar carries out current delivery, because each copper bar wants die sinking, therefore the research and development of products time is long, and input cost is large, and copper bar interlocks cabling, cause wiring loaded down with trivial details, the heaviness of electrical module, account for very large space, in addition because copper bar connects by using screw, be easy to cause loosening of copper bar, so that high pressure electric leakage, do not reach that the wiring required in engineering machinery is attractive in appearance, high reliability, fail safe; Single PCB scheme is walked due to big current small area analysis together, and wires design difficulty, final products size can be large.
Summary of the invention
For the problems referred to above that prior art exists, the object of this invention is to provide a kind of electric current wiring cost low, installation and maintenance are easy, the multi-layer PCB central power distribution box of high security and high reliability.
For achieving the above object, the present invention adopts following technical scheme: multi-layer PCB central power distribution box, comprises insulation box body, is positioned at multiple PCB and at least one pair of conductive pin of insulation box body; Described multiple PCB is parallel to each other by layer setting, is provided with insulating paper insulation, and is connected by insulated screw between adjacent two layers PCB between adjacent two layers PCB; In described often pair of conductive pin, one end of two conductive pin is connected in the PCB of different layers, and the other end of two conductive pin stretches out from outermost PCB, facilitates wiring.
As preferably, described every layer of PCB adopts grid network structure.
As preferably, described insulation box body adopts plastic insulation box body.
As preferably, between described PCB and insulated screw, be provided with insulating washer.
Relative to prior art, the present invention at least tool has the following advantages:
1, production cost is low.Existing copper bar is with the metalline of itself; half all will plate protective layer in addition, also wants each and every one die sinking, and PCB only needs will pay hundreds of yuan in first time when PCB makes; later along with the increase of amount, average cost only needs tens yuan.
2, wiring simplifies, neatly.The wiring of tradition big current needs to use copper bar, and copper lug, cross-sectional area reaches 1.5mm 2thick line, along with the complexity of circuit, cause the overpass type of copper bar to transmit; And PCB that all cablings are all designed in PCB is two-layer up and down, along with the block number of PCB increases, PCB equally can be clean and tidy design above, only need in PCB, weld corresponding connector terminals, reach the most simplification of its wiring.
3, easy to assembly.Include the installation wiring of wiring board due to conventional mounting and fix, loaded down with trivial details copper bar cabling, difficultly consuming time, and invention multi-layer PCB central power distribution box only needs on PCB terminal soldering, and in press-in in box body, fixed screw of screwing on.
4, fault is easily investigated.Traditional wired method is difficult to get rid of out of order place, and multi-layer PCB central power distribution box of the present invention is designed with its easy removable feature, is very easy to the place observing fault.
5, Stability Analysis of Structures.The flexibility of tradition cabling, cause rocking and loosening of cabling, be very easy to cause the mixed and disorderly of circuit, and the cabling of multi-layer PCB central power distribution box of the present invention is fixed in PCB all completely, the clean and tidy characteristic that carries of PCB itself, improves the clean and tidy, attractive in appearance of product more in addition.
6, reliability is high.Because traditional cabling extremely easily causes loosening of circuit in vibration environment, line and line, friction between line and copper bar, that circuit causes short circuit and causes spark, be easy to cause damage and accident, and the cabling in multi-layer PCB central power distribution box of the present invention in PCB is fixed, be separated completely between the lines, become primary insulation, insulating paper is adopted to carry out secondary insulating between adjacent two layers PCB, PCB shell adopts plastic casing to carry out three minor insulation, its fail safe of maximum raising, the fixed characteristic of the insulation characterisitic that PCB carries and circuit, even if make the circuit on wiring board have metal also can not short circuit above, also can not be close together between circuit, very large degree improves its reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of multi-layer PCB central power distribution box of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Structure and the principle of multi-layer PCB central power distribution box are described in detail in detail for two PCB below.
See Fig. 1, multi-layer PCB central power distribution box, comprises insulation box body, is positioned at two PCB and at least one pair of conductive pin of insulation box body.During concrete enforcement, insulation box body can adopt plastic insulation box body.
PCB is parallel to each other and arranges by layer, is provided with insulating paper and insulate 3, and be connected by insulated screw 2 between upper strata PCB 1 with lower floor PCB 4 between upper strata PCB 1 and lower floor's PCB 4; Insulated screw 2 can be plastic screw.During concrete enforcement, insulated screw 2 can be four, be separately positioned on the corner of upper strata PCB 1 and lower floor's PCB 4, thus by layer PCB 1 and stable the linking together of lower floor's PCB 4, simultaneously, upper strata PCB 1 is connected by insulated screw 2 with lower floor PCB 4, makes to have certain distance between upper strata PCB 1 and lower floor's PCB 4, thus prevents short circuit between upper strata PCB 1 and lower floor's PCB 4 as much as possible.
More stable in order to what multiple PCB was connected, prevent from rocking between multiple PCB and be connected loosening, insulating washer can also be set between PCB and insulated screw.During concrete enforcement, it can be insulating washer plastic washer.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
