Description

TECHNICAL FIELD

[0001] The utility model relates to cable detection field, concretely is a kind of cable internal resistance detection wiring structure. BACKGROUND

[0002] The main function of the aircraft power distribution system is to transmit the electrical energy generated by the aircraft generator to the busbar in different line systems and different power distribution modes, and then to the electrical equipment through the busbar. In addition to the configuration system, the aircraft power distribution system also includes control and protection circuits. In a two-wire system, the positive and negative terminals of the generator and the electrical equipment are connected by wires (or busbars). The advantage of the former is to reduce the weight of the wires, and the disadvantage is that any wire that comes into contact with the housing will cause a short circuit. The use of a two-wire system can prevent short circuits. The cables of the aircraft require testing, and the transient current of a typical cable is 2000-6000A. The cable is made of copper wire, and excessive internal broken copper wire will affect the internal resistance. Excessive transient current can cause cable burning and even engine burning.

[0003] However, the traditional wiring mechanism is usually clamped by a clip using a resistance meter. Since the thickness of the aircraft cable varies, the clip may not be able to make good contact with the cable. SUMMARY

[0006] As a further scheme of the utility model: an elastic rotating shaft is installed between the rotating collar and the swing seat, and a limiting baffle is installed on one side end of the wire slot close to the swing seat.

[0007] As a further scheme of the utility model: a fixed ear plate is installed on one side end of the rotating collar away from the swing seat, and a positioning hole is formed in the fixed ear plate.

[0008] As a further scheme of the utility model: the inclined pipe and the rotating collar are throughly arranged, and the electrically conductive wire and the electrically conductive wire are electrically connected.

[0009] As a further scheme of the utility model: the constant current machine is connected with a detection power supply.

[0010] As a further scheme of the utility model: the limiting baffle is fixedly connected with the rotating ring, and the rotating ring is rotatably connected with the swing base through the elastic rotating shaft.

[0011] As a further scheme of the utility model: the rotating ring and the swing base are both made of insulating material.

[0012] As a further scheme of the utility model: a limiting pin is arranged in the positioning hole.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] After the power connection binding wire is transmitted out from the inclined pipe in the opposite rotating ring in the overall cross type, the power connection binding wire is pulled out to the outside, the exposed position of the cable to be detected is contacted and fastened with the power connection binding wire, and the power connection binding wire is positioned, so that the close contact between the wiring mechanism and the cable can be realized during power supply.
