Description

A kind of instrument appliance box

Technical field

The utility model design relates to the automobile electrical equipment box field, is specifically related to a kind of instrument appliance box.

Background technology

Substantially all be thicker big electric current wiring at present on the circuit card of the instrument appliance box of automobile, there are not very thin signal detection line and control line, big electric current wiring will take a lot of board area, installing space on the automobile is very limited simultaneously, for making the instrument appliance box can hold more relay, safety plate, adaptor union, the instrument appliance box mostly adopts two parallel modes that are welded together of circuit card, has so just increased a circuit card.The high-current circuit plate is very expensive, being welded and testing also relatively difficulty of two circuit cards simultaneously, and such structure has also just determined relay socket, safety plate socket and bus-bar can only be put into the one side of circuit card.

The utility model content

The utility model design-calculated purpose provides a kind of instrument appliance box, and it can save the installing space of circuit card, and practicality is reliable and cost is lower.

To achieve these goals, the utility model design is by the following technical solutions:

A kind of instrument appliance box, wherein, described instrument appliance box 3 one sides are provided with relay socket, safety plate socket, connector body and detect feedback resistance, and another side is provided with bus-bar 4.

Further, described instrument appliance box 3 and car body controller 1 by contact pin or/and connecting strap captive joint.

Further, described instrument appliance box 3 is fixedly connected into " L " type with car body controller 1.

The utility model design-calculated beneficial effect is:

The utility model adopts a circuit card, relay socket, safety plate socket, connector body are installed in the one side of circuit card, and the bus-bar of super-high-current is put into the another side of circuit card, made full use of the area of circuit card, the space is very under the condition of limited in automobile, so integrated installing space of having saved; Bus-bar adopts and conducts electricity very well, the copper plate of copper content 99%, greatly reduces cal val; Bus-bar is welded by a plurality of feets and has guaranteed fastness on the circuit card, and the spacing bus-bar main body that makes of feet is higher than circuit card, has guaranteed the mutual security in bus-bar and circuit card loop.The utility model design is in strict accordance with National Standard QC/T707-2004 " carried out a large amount of verification experimental verifications, instrument appliance box every stable and reliable for performance, cost is lower, the structure uniqueness.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification sheets or the accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Also design is described in further detail to the utility model in conjunction with the accompanying drawings below by specific embodiment:

As shown in Figure 1, this instrument appliance box 3 is made up of a double-sided PCB, the one side of circuit card be welded relay socket, safety plate socket, connector body and detect feedback resistance, safety plate 6 and relay 5 are plugged on respectively on safety plate socket and the relay socket; The another side of the circuit card bus-bar 4 that is welded.Bus-bar 4 comprises the loop of BAT, ACC, IG1, IG2, GND and some super-high-currents, and the loop of relatively low current still routes on the circuit card, has made full use of the area of circuit card.Bus-bar 4 adopts and conducts electricity very well, the copper plate of copper content 99%, greatly reduces cal val, and copper plate thickness is 0.8mm～1.0mm.According to by the size of electric current, the weight balancing and the heating harmony of circuit card, can suitably increase or reduce the height of bus-bar 4.Bus-bar 4 is welded by a plurality of feets and has guaranteed its fastness on the circuit card, and spacing bus-bar 4 main bodys that make of feet are higher than circuit card, has guaranteed the mutual security of bus-bar 4 with the circuit card loop.

Instrument appliance box 3 is integrated together by contact pin and connecting strap with car body controller 1, and RKE receiver module 2 is fixed on the car body controller 1.In the present embodiment, instrument appliance box 3 is fixedly connected into " L " type with car body controller 1.Instrument appliance box 3 provides power supply and AD detection signal to car body controller 1, and the output signal of car body controller 1 is connected to the relay line of instrument appliance box 3 and wraps.

Instrument appliance box 3 comprises two parts: the control output of the distribution section of instrument appliance box 3 and car body controller 1.The distribution section of instrument appliance box 3 is the control that the part current consumer on the automobile is not subjected to car body controller 1, and they only need instrument appliance box 3 to provide power supply for it; This part comprises radio receiver, combination instrument, safety air bag, CD player, skylight, Cigarette lighter, automatic seat, side mirror, 4WD, the preceding hydroelectric machine of scraping.Instrument appliance box 3 is subjected to car body controller 1 control part, has only when car body controller 1 output useful signal, and the relay ability adhesive of control respective load, function corresponding could realize.For example back defrosting control is when car body controller 1 output low level arrives relay coil, relay adhesive at this moment, back defrosting work; Export high level to relay coil when car body controller 1, at this moment relay disconnects, and the back defrosting is not worked.This part comprise right electric window output, left electric window output, central controlled lock output, after scrape hydroelectric machine output, back defrosting output, fog tail lamp output, steering indicating light output, the output of tail-gate lock motor, ceiling light output.These two parts all will can avoid line short that whole car body controller 1 is caused damage through the distribution of safety plate like this.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
