Background technology
At present, the temperature transducer on motor-car is mainly used in the collection of motor-car axle temperature, gear-box and motor temperature.Because pass
Sensor installation site is different, therefore has different requirements to vibration, acquisition precision and wiring.In the past traditional temperature transducers
Device is fixed using the dead outlet method of screw-type, so very high to bogie, gear-box or motor drilling precision and depth requirements,
Especially electromechanical transducer, the longer ＞ 100mm of reach, except itself popping one's head in, long concentricity requirement is high, manufacturing cost mistake
Height, also motor is punched and requires harsh.Concentricity is bad, it is difficult to assembles, the too deep probe in hole can not touch thermometric surface, to surveying
Warm precision has an impact, and hole is excessively shallow, and sensor threads part is twisted less than bottom, and probe easily shakes disconnected under vibrating conditions.
Utility model content
The purpose of this utility model is that existing temperature transducer uses fixedly mounted and flimsy problem mostly, if
Count a kind of motor-car extension type temperature transducer that can actively stretch under external force.
The technical solution of the utility model is：
A kind of motor-car extension type temperature transducer, it includes internal temperature element 1, it is characterized in that described inside is surveyed
Warm element 1 is encapsulated in probe 2, and the upper end of described probe 2 is inserted into screw thread bottom 3 and the step body by being set on probe
4 realize axially position, and the rotary top 5 that can be rotated wherein is provided with described threaded base 3, is led to therebetween
Cross back-up ring 15 and realize axially position so that can only be relatively rotated between two liang；Rotary top 5, which is connected with, withholds mouth 6, withholds mouth
6 withhold on mouth provided with reversed acanthoid structure so that rubber wire bushing 7 can be tightly placed in, and shielded cable 8, which passes through, withholds mouth 6 and inside
Temperature element 1 is connected, and spring 9 is sleeved on probe 2, and its one end offsets with step body 4, and the other end offsets with rotary top 5,
Probe 2 overcome spring 9 elastic force can be between threaded base and rotary top axial passage in move axially.
Described rotary top is provided with blanking cover 10, and rubber seal 11 is added between blanking cover 10 and rotation top cover.
The bottom of described rotary top 5 is provided with annular groove, and the top of threaded base 3 is provided with the annular protrusion to match,
Described annular protrusion, which is inserted in entered annular groove, enables both to realize the sealing of faying face while relative rotation.
The part that described rubber wire bushing 7 is sleeved on the reversed acanthoid structure withheld on mouth 6 adds locking buckle
Pressure ring 12.
The beneficial effects of the utility model：
The utility model has that temperature measurement accuracy and scope are higher, and outlet is flexible, antivibration, dust-proof and waterproof（IP67）Performance is good
The advantages of.

Fig. 1 is outline structural diagram of the present utility model.
Fig. 2 is Fig. 1 dimensional decomposition structure diagram.
Fig. 3 is Fig. 1 cross section structure diagram.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
A kind of motor-car extension type temperature transducer, it includes internal temperature element 1, probe 2, threaded base 3, rotation top
Portion 5, mouth 6, rubber wire bushing 7 and shielded cable 8 are withheld, as shown in figure 3, it is outer shaped like Fig. 1, dimensional decomposition structure such as Fig. 2
Shown, described inside temperature element 1 is encapsulated in probe 2, and the upper end of described probe 2 is inserted into threaded base 3 and led to
Cross the step body 4 set on probe and realize axially position, be provided with what can be rotated wherein in described threaded base 3
Rotary top 5, axially position is realized by back-up ring 15 therebetween so that can only be relatively rotated between two liang；Described rotation
The bottom for turning top 5 is provided with annular groove, and the top of threaded base 3 is provided with the annular protrusion to match, and described annular protrusion is inserted
Entering in entered annular groove enables both to realize the sealing of faying face while relative rotation；Rotary top 5 is connected with button
Pressure mouth 6, withhold mouth 6 and be provided with reversed acanthoid structure 13（Such as Fig. 2）Withheld so that rubber wire bushing 7 can be tightly placed on mouth and buckle
Pressure ring 12 is locked, and shielded cable 8 is connected with internal temperature element 1 through withholding mouth 6, and spring 9 is sleeved on probe 2, it
One end offsets with step body 4, and the other end offsets with rotary top 5, probe 2 overcome spring 9 elastic force can in threaded base and
Moved axially in axial passage between rotary top.Described rotary top is provided with blanking cover 10, blanking cover 10 and rotation top cover
Between add rubber seal 11.
Operation principle of the present utility model：Sensor probe is built-in with temperature element, and temperature element passes through high temperature resistant wire
Collection capacity is spread out of.Probe and temperature element are sealed using high insulation, the casting glue 14 of high thermal conductivity coefficient.Even if popped one's head in after sealing
Inner inlet nor affects on normal operation of sensor.There are individual step body 4, one end phase of step body 4 and spring 9 in probe middle and upper part
Support, the other end and the rotary top of spring offset, and after the completion of assembling, probe can extrude spring so as to up and down.Sensor top
Portion and threaded base respectively have a notch, and notch is sticked into by back-up ring, upper and lower two parts is individually rotated.And top of popping one's head in
Respectively there are a groove and boss with base contacts face, boss and groove engaging in assembling, so while rotation is not influenceed
Increase anti-dust performance.Top blanking cover puts that tighten after rubber ring also can effective dust waterproof.Withhold mouth by screw thread with it is rotatable
