Abstract
The utility model relates to a safety device in the field of automobiles, particularly a device capable of automatic recognizing whether a fuse is fused or not. The utility model is composed of a set of fuses 8, a base for fixing the fuses 8, and a housing 1 which can cover the fuses 8 and the base 2. The utility model is characterized in that each fuse 8 is connected in parallel with a fuse break testing circuit, and the output terminal of the fuse break testing circuit is connected with the signal input terminal of an acoustooptic alarm circuit; the luminous part of a luminous diode for optical alarm in the acoustooptic alarm circuit is exposed outside the housing 1. Because both ends of each fuse is provided with one fuse break testing circuit, acoustooptic alarm can be instantly realized when a fuse breaks, and the wire breaking position can be correctly pointed out.
Description
The utility model relates to the security personnel's device in a kind of automotive field, and the fusing that particularly can discern fuse automatically whether.
The fuse block of using on the automobile is by the multichannel fuse base at present, and plug type fuse sheet, pipe and loam cake are formed.When a certain road fuse opened circuit because of fuse, fuse block can only outer fault situation come analysis and judgement without any indication, and one tunnel road ground is extracted the cartridge fuse-link that inserts and checked again.This test mode is very inconvenient, concerning the driver, often influences normal driving because can not in time find abort situation.
The purpose of this utility model is to avoid above-mentioned weak point and a kind of automatic alarm fuse case that opens circuit that is used on the automobile is provided.It can be reported to the police with acousto-optic in time, and can lay one's finger on the position of being broken.
The purpose of this utility model can realize by following technical proposal:
The utility model is by one group of fuse, fixedly the base of fuse and encase fuse and the shell of base is formed.It is characterized in that: fracture of wire testing circuit in parallel on each fuse, the output of each fracture of wire testing circuit inserts many inputs or the input of door and the signal input part of optical alarm circuit, the output end signal control audible alarm circuit of many inputs or door.The illuminating part that is used for the light-emitting diode of light warning in the described sound light alarming circuit is exposed to outside the shell.When fuse was intact, the current potential at two ends was identical, and acoustic-optic alarm is not worked.Riches all the way when giving birth to fault fusing when any, and two ends produce potential difference, and testing circuit is output signal at once, lights the light-emitting diode on this road, and drives audible warning, sends the ground sound that ticks.It can determine the position of broken string in time at this moment.
The utility model compared with prior art has following advantage: simple in structure, cost is low, because a testing circuit all is equipped with at each fuse two ends, road, fuse is once the energy sound and light alarm at once that opens circuit, can correctly point out the position of breaking, bring convenience in the maintenance to the driver, in driving, can in time pinpoint the problems trouble-saving generation.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical sectional view of the utility model front view;
Fig. 3 is a block diagram of the present utility model;
Fig. 4 is circuit theory diagrams of the present utility model.
Wherein: 1. shell, 2. base, 3. earth terminal, 4. light-emitting diode, 5. circuit board, 6. acoustic alarm, 7. box, 8. fuse.
The utility model by one group of fuse 8, fixedly fuse 8 base 2 and encase fuse 8 and the shell 1 of base 2 is formed.Embodiment presses accompanying drawing 3 and accompanying drawing 4.One termination load of each fuse of accompanying drawing 4.Fracture of wire testing circuit in parallel on each fuse, this fracture of wire testing circuit is an AND circuit.Fracture of wire testing circuit 1 in parallel on the fuse 1, fracture of wire testing circuit 2 in parallel on the fuse 2, n in parallel fracture of wire testing circuit on n the fuse that use the same method, n is a positive integer.The output of fracture of wire testing circuit in parallel all is connected on the input of input OR circuit more than on each fuse, and respectively being connected to R11, LED1 and R12, LED2 and R1n, LEDn in the output of the input of many inputs OR circuit and each road fracture of wire testing circuit is optical alarm circuit.Be connected to a multi-resonant oscillating circuit on the output of many inputs OR circuit, the output wave of oscillation produces audible alarm.The illuminating part that is used for the light-emitting diode 4 of light warning in the described sound light alarming circuit is exposed to outside the shell 1.Earth terminal 3 is equipped with in the outside lower end of shell 1, box 7 is housed below the base of fuse 8, and circuit board 5 and acoustic alarm 6 are housed in the box 7.When the fuse operate as normal, the two ends potential difference is zero, no signal output, and acoustic-optic alarm is not worked.In case fuse opens circuit, the fuse two ends produce potential difference, make the indication light-emitting diode conducting of opening circuit on this road after testing circuit amplifies this potential difference signal, thereby send the disconnected light signal of this road fuse.After any one light-emitting diode conducting, all can pass through or door startup multivibrator.HTD is sounded the alarm, and it can determine the position of broken string in time.
Claims (2)
1, a kind of automatic alarm fuse case that opens circuit that is used on the automobile, by one group of fuse 8, fixedly fuse 8 base 2 and encase fuse 8 and the shell 1 of base 2 is formed, it is characterized in that: fracture of wire testing circuit in parallel on each fuse, the output of each fracture of wire testing circuit inserts input or the input of door and the signal input part of optical alarm circuit of many inputs or door, the output end signal control audible alarm circuit of many inputs or door.
2, the automatic alarm fuse case that opens circuit that is used on the automobile according to claim 1 is characterized in that: the illuminating part that is used for the light-emitting diode of light warning in the described sound light alarming circuit is exposed to outside the shell 1.
