Description
Technical field
The utility model relates to arrangement of temperature sensor design and applied technical field, and a kind of split type temperature sensor is provided especially.
Background technology
At present on railway, the motor train unit of part type number now need increase the sensor device of the temperature of monitoring axle box, gear case, and common temperature sensor is integral structure at present, cause installing difficulty because operating space is little, and install, when dismounting easily causes cable rotation stressed.This product adopts split type structural design, can better realize workablely, has improved installation reliability, current domestic without Related product.
People urgently wish to obtain the good split type temperature sensor of a kind of technique effect.
Utility model content
The purpose of this utility model is to provide that a kind of easy to assembly, sealing/insulation/withstand voltage is reliable, version is simple, measuring accuracy is high, has the temperature sensor of the split-type structural of versatility
Described split type temperature sensor is constructed as follows: housing 1, hold-down nut 3, copper packing 4, steel wire band 5, rubber sheath 6, cable-assembly 7; The housing 1 of the main installing component of described conduct is connected with hold-down nut 3, described copper packing 4 is between housing 1 and hold-down nut 3, described cable-assembly 7 is positioned at hold-down nut 3, copper packing 4 and housing 1, described rubber sheath 6 is enclosed within cable-assembly 7 outsides, steel wire band 5 is fixed on rubber sheath 6 outsides, after housing 1 and hold-down nut 3 are threaded, fix cable-assembly 7, this assembling mode can ensure that cable-assembly 7 is not subject to revolving force, avoids occurring damaged phenomenon; It is rear fixing with steel wire band 5 that rubber sheath 6 is enclosed within cable-assembly 7, mainly plays protective wire cable assembly 7.
Described cable-assembly 7 is constructed as follows: cable 8, holder 9, protection tube 10 and platinum resistance 11; Protection tube 10 is fixedly connected with by soldering with holder 9; And with casting glue, protection tube 10 and holder 9 are carried out to embedding and fix, platinum resistance 11 connects by being weldingly connected with cable 8, and inserts in protection tube 10.And the afterbody of holder 9 is closed up to crimping with further fixed cable 8.Described cable-assembly 7 is critical pieces of Realization of Product measuring ability.
Described housing 1 is provided with O type circle 2, the groove that described O type circle 2 is positioned on housing 1 with hold-down nut 3 junctions.
Described split type temperature sensor rotates axletree or gear rotates the axle box temperature variation causing and is converted into electric signal and exports to control desk, thereby monitors the real-time temperature of railway vehicle axle box or gear case.The difficult problems such as difficulty, cable stress are installed have been solved simultaneously.
Described split type temperature sensor can be widely used in the monitoring of Multiple Type motor train unit axle box or gear case temperature, realizes the instant measurement to axle box or tooth case temperature, and temperature survey, for safe-guard system provides axle temperature information, ensures safe train operation.
Described split type temperature sensor, housing 1 and hold-down nut 3 are split type, easy to assembly, sealing/insulation/withstand voltage is reliable, version is simple, measuring accuracy is high, have versatility, this product can be widely used in the temperature survey of railway vehicle axle box or gear case, has comparatively huge economic worth and social value.
