Abstract
The utility model discloses a printed circuit board (PCB) with point discharge, which comprises a substrate, copper lines paved on the substrate and two corresponding sets of discharge areas arranged on the copper lines, wherein the discharge areas are arranged at a common mode inductance at the input end of the substrate, and the discharge areas are jagged point discharge areas. The amount and the spacing of points of the point discharge area are modified so that the PCB can be applied to places with different requirements on lightning protection. The PCB with the point discharge is convenient to assemble and has high production efficiency, low cost and high reliability.
Description
Technical field
The utility model relates to the electromagnetism components and parts, relates in particular to a kind of printed circuit board (PCB) with point discharge.
Background technology
Along with raising, in the printed circuit board (PCB) of various electric equipment products, all need design special circuit at lightning protection to various electric equipment products lightning protection performance requirements.Present printed circuit board (PCB), in order to improve anti-lightning performance, normally at the special protection circuit of printed board power input design, this structure has the following disadvantages: 1, design specialized lightning protection circuit in printed board, it is bigger to take up room, cost is higher, and 2, the individual devices inefficacy can cause the whole protection circuit malfunction in the protection circuit, reliability is lower.
The utility model content
The purpose of this utility model is to solve the defective that exists in the above-mentioned prior art, proposes a kind of printed circuit board (PCB) with point discharge, and this circuit board is with low cost, reliability is high.
For solveing the technical problem, the technical scheme that the utility model proposes is: design a kind of printed circuit board (PCB) with point discharge, comprise substrate, copper sheet circuit on the substrate is laid in, with be arranged on the copper sheet circuit on two groups of relative region of discharges, described region of discharge is positioned at the power input common mode inductance place of substrate, and wherein, described region of discharge is zigzag point discharge district.
In an embodiment of the present utility model, the tip angle in described point discharge district is less than 90 degree, and tip height H1 is 1.0 millimeters to 2.0 millimeters, and the distance H 2 between two groups of corresponding tips is 1.5 millimeters to 2.0 millimeters.Most advanced and sophisticated quantity can be provided with arbitrarily according to printed circuit board area and protection needs.Do and reveal the copper processing in described point discharge district.
Compared with prior art, this printed circuit board (PCB) is easy to assembly, production efficiency is high, good reliability, with low cost.By revising most advanced and sophisticated quantity and adjusting most advanced and sophisticated spacing, make printed circuit board (PCB) can be applied to that lightning protection is had the different places that require.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
Fig. 1 is a traditional printing circuit board schematic diagram;
Fig. 2 is the utility model printed circuit board (PCB) schematic diagram.
Embodiment
Fig. 1 shows traditional printing circuit board lightning protection circuit schematic diagram, as can be seen from the figure must insert special-purpose lightning protection circuit before the copper sheet line input 1 of traditional printing circuit board, through common mode inductance 3, from inductance output end 2 place in circuit plates.Lightning protection circuit takies than large space, and the individual devices inefficacy can cause haveing suffered lightning protection circuit and lost efficacy, and reliability is relatively poor.
The printed circuit board (PCB) of the utility model design comprises substrate, the copper sheet circuit on the substrate that is laid in, be arranged on the copper sheet circuit on two groups of relative region of discharges, described region of discharge is positioned at the power input common mode inductance place of substrate.As shown in Figure 2, power input common mode inductance place 3 is provided with two groups of relative copper sheet circuits 1 and 2, and copper sheet circuit 1 is an input, and copper sheet circuit 2 is an output, and two groups of tinsel conductor terminal portions are provided with jagged point discharge district 4.The tip angle in point discharge district is less than 90 degree, and tip height H1 is 1.0 millimeters to 2.0 millimeters, and the distance H 2 between two groups of corresponding tips is 1.5 millimeters to 2.0 millimeters.Most advanced and sophisticated quantity can be provided with arbitrarily according to printed board area and protection needs.
As thunderstorm hour, the surge current that thunder and lightning causes enters printed substrate by incoming line, in the meeting repid discharge of the point discharge district at common mode inductance place, the surge current that thunder and lightning is caused is converted into the electric arc of moment, thereby carry out power conversion, the surge current that thunder and lightning is caused can not damage other device on the printed substrate.By this, the printed circuit board (PCB) that the utility model proposes has realized utilizing wiring board design itself to reach the lightning protection function, does not increase additional device, with low cost, easy to operate, and the processing of tin window is done out in the point discharge district, window and distinguish meeting tin sticky when producing, increase conveyance capacity, reliability is higher.
Better embodiment of the present utility model has below been described in conjunction with the embodiments; but the those of skill in the art in the present technique field are to be understood that; these only illustrate, and not deviating from principle of the present utility model and essence can all should fall within the scope of the utility model protection various changes or the modification that these execution modes are made.
