Description
Technical field
The utility model relates to a kind of wire harness protection pipe, is specifically related to a kind of self diagnosis wire harness protection pipe device, belongs to automobile circuit technical field.
Background technology
Carrying out often needing in new automobile development process to make experimental model at present, and service test sample car carries out various endurance test.But, because test vehicle major part part is manual exemplar, mated condition cannot be guaranteed before, often occurs the phenomenon that wearing and tearing wire harness causes vehicle trouble even to catch fire, therefore, how accurate management and control is carried out to wire harness state and become the problem that in complete vehicle test, must solve.So, urgently design a kind of self diagnosis wire harness protection pipe device that can carry out accurately monitoring to wire harness.
Summary of the invention
The utility model coordinates imperfect for solving manual sample car part, easily causes wire harness premature aging, breakage, causes the problem that vehicle trouble even catches fire, and then provides a kind of self diagnosis wire harness protection pipe device that can carry out accurately monitoring to wire harness.
The utility model for solving the problems of the technologies described above taked technical scheme is:
Self diagnosis wire harness protection pipe device of the present utility model; comprise protective casing and controller; described protective casing uniform winding is on protected wire harness; two resistive conductors are embedded with in wire harness; two resistance wire parallel arrangements, are connected by multiple conducting wires between two resistance wires, and the wire harness in protective casing is connected with controller by detection line; controller internal series-connection has stabilized power supply, ammeter, break-make indicator light and master switch, and controller, detection line and wire harness form occlusion detection circuit.
The self diagnosis wire harness protection pipe device of such scheme, its structure utilizes two resistance wires be embedded in protective casing, and to wire harness, whether breakage is monitored.Because protective casing is wrapped in wire harness outermost layer.So protective casing receives wearing and tearing at first, when wire is destroyed, illustrate that wire harness breaks down, simultaneously by resistance between measurement two resistance wires, by resistance conversion relation, measure abration position.
Design further scheme: in order to play the effect of insulation better, protective casing is fiberglass insulation tube.
Design further scheme: in order to ensure the monitoring to wire harness wear condition, the pipe thickness of protective casing is 2-5mm.
Scheme is designed further: wire harness is helical form wire harness, and protective casing is enclosed within wire harness in the shape of a spiral.
Scheme is designed further: in order to regulate the least unit of monitor for faults point position, controller also comprises variable resistor, and variable resistor is arranged on occlusion detection circuit.
The beneficial effects of the utility model are: the utility model accurately can be monitored wire harness, and this equipment has installation, lays conveniently, the features such as flexibility is high, safe and reliable, and can measure position of failure point accurately and fast.For finding that fault provides important evidence as early as possible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the profile of protective casing;
Fig. 3 is the automatically controlled figure in inside of controller;
In figure: 1-resistance wire, 2-wire, 3-protective casing, 4-detection line, 5-controller, 6-break-make indicator light, 7-wire harness, 8-master switch, 10-stabilized power supply, 11-ammeter, 12-variable resistor.
Embodiment
Embodiment: composition graphs 1-Fig. 2 is described; self diagnosis wire harness protection pipe device of the present utility model; comprise protective casing 3 and controller 5; protective casing 3 uniform winding is on protected wire harness; two resistive conductors 1 are embedded with in wire harness; two resistance wire 1 parallel arrangements; connected by multiple conducting wires 2 between two resistance wires 1; wire harness in protective casing 3 is connected with controller 5 by detection line 4; controller 5 internal series-connection has stabilized power supply 10, ammeter 11, break-make indicator light 6 and master switch 8, thus forms closed circuit.As shown in Figure 3, according to variable resistor principle, when wire harness receives abrasion condition, resistance wire 1 certainly will be destroyed the open circuit causing protective casing 3 internal circuit.Thus; cause the change of protective casing 3 internal circuit resistance; namely wear and tear; break-make indicator light 6 is lighted; prompting wire harness 7 receives damage, and can be gone out the physical distance of distance detection line 4 by the numerical computations of the ammeter 11 of controller 5 li, plays protection wire harness 7 body, finds out the effect of wear point fast; by the resistance value of the variable resistor 12 of conditioning controller 5 inside, the least unit of monitor for faults point position can be realized simultaneously.
The exemplary illustration of present embodiment just to this patent, does not limit its protection range, and those skilled in the art can also change, as long as no the Spirit Essence exceeding this patent, in the protection range of this patent its local.
