Referring to shown in Figure 1, safety and circuit mainly are made up of a plurality of discrete components such as transformer, photoelectrical coupler, rectifier bridge, electric capacity and resistance.The designer when carrying out safety and circuit design, need with above-mentioned discrete device one by one layout, the wiring be installed on the printed circuit board (PCB).
The shortcoming of prior art is: during the circuit theory design, because the circuit complexity causes printed board to draw difficulty and the increasing of printed board area accordingly; During the design like product, all must repeat the similar design process.
The utility model content
In view of this, the utility model provides a kind of safety and circuit module, and the printed board drafting that exists with the solution prior art is difficult, the printed board area strengthens and the problem of design iterations, and technical scheme is as follows:
A kind of safety and circuit module, described safety and circuit module are the circuit module that has encapsulated a plurality of discrete components, and described a plurality of discrete components comprise: photoelectrical coupler, transformer, rectifier bridge, switch triode, current-limiting resistance and electric capacity; And described safety and circuit module comprise: two pairs of square wave input interfaces, a pair of power input interface, a pair of direct voltage output interface and a pair of debugging resistance input interfaces.
Preferably, in above-mentioned safety and the circuit module, described photoelectrical coupler is the quick photoelectrical coupler of two-way.
Preferably, in above-mentioned safety and the circuit module, described current-limiting resistance is the paster current-limiting resistance.
Preferably, in above-mentioned safety and the circuit module, described electric capacity comprises: four-head electric capacity and shunt capacitance.
As can be seen from the above technical solutions, the utility model is with a plurality of discrete components, comprise photoelectrical coupler, transformer, rectifier bridge, switch triode, current-limiting resistance and electric capacity, be encapsulated as one independently, module with complete function, unified input/output interface externally is provided, the designer is when carrying out safety and circuit design, only need on the basis of safety that the utility model provides and circuit module, increasing a spot of peripheral circuit gets final product, thereby simplified circuit design, make things convenient for the printed board drafting, reduced the printing area, avoided design iterations.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the circuit theory diagrams of safety and circuit;
A kind of safety that Fig. 2 provides for the utility model embodiment and the structural representation of circuit module.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to shown in Figure 2, safety that the utility model embodiment provides and circuit module, for having encapsulated the circuit module of a plurality of discrete components, described a plurality of discrete components comprise: photoelectrical coupler, transformer, rectifier bridge, switch triode, current-limiting resistance and electric capacity; And described safety and circuit module comprise: two couples of square wave input interfaces (IN1, IN1H, IN2, IN2H), a pair of power input interface (+24V, 024V), a pair of direct voltage output interface (OUT, OUTH) and a pair of debugging resistance input interface (TS1, TS2).
Wherein, photoelectrical coupler can be selected the quick photoelectrical coupler of two-way for use; Current-limiting resistance can be selected the paster current-limiting resistance for use; Electric capacity comprises four-head electric capacity and shunt capacitance.
Actual when encapsulating, transformer, rectifier bridge, four-head electric capacity and switch triode are welded on the front of printed circuit board (PCB); Photoelectrical coupler, current-limiting resistance and shunt capacitance are welded on the reverse side of printed circuit board (PCB).
Wherein, during the transformer layout, should note reducing the cutting of the magnetic line of force, allow two transformers keep a determining deviation, and on direction, keep two magnetic directions vertical the printed board lead.
In addition, two pairs to square wave input interface (IN1, IN1H, IN2, IN2H) and a pair of direct voltage output interface (OUT OUTH) designs two ends, the left and right sides in module respectively; When printed circuit board layout, wiring, according to streamline direction from left to right, to guarantee input and the isolation of exporting.
In addition, (+24V, 024V) (TS1 TS2) designs upper/lower terminal in module respectively to a pair of power input interface with a pair of debugging resistance input interface.
From the foregoing description as can be seen, the utility model is with a plurality of discrete components, comprise photoelectrical coupler, transformer, rectifier bridge, switch triode, current-limiting resistance and electric capacity, be encapsulated as one independently, have a module of complete function, unified input/output interface externally is provided, can simplifies schematic diagram and printed board design greatly; By integrated, can make complicated circuit be converted into the simple module of construction packages, make the designer needn't get involved the detail of inside modules too much, but pass through to select one or several integration standard module and appropriate combination, just can finish the design of product, avoid design iterations; Correspondingly assemble and debug also and simplified, can also effectively reduce the printed board size.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
