Abstract
The utility model is related to a kind of temperature sensor for facilitating core pulling; including thermometer boss, temperature sensor, holddown spring, lead, upper protection pipe, positioning pipe, terminal box; the temperature sensor is connected with lead; form temperature measuring point; it is furnished with holddown spring outside lead; the temperature sensor, lead, holddown spring and positioning pipe form a whole, and are placed in thermometer boss and upper protection pipe, and the terminal box is connected through a screw thread protection pipe.When temperature sensor is during use; when breaking down or measure inaccurate, terminal block cover can be directly unclamped, the entirety of temperature sensor, lead, holddown spring and positioning pipe composition is extracted out out of terminal box; protection pipe need not be replaced with, not only facilitates but also expense can be saved.Holddown spring can allow temperature sensor to be close at the top of thermometer wrap pipe orifice so that thermal response speed accelerates；Holddown spring also has cushioning effect for temperature sensor.
Description
Technical field
The utility model is related to a kind of temperature sensor, especially a kind of temperature sensor for facilitating core pulling.
Background technology
Typical temperature sensor is, for supporting with display instrument and computer, to be widely used in oil, chemical industry, steel, electricity
The industrial departments such as power.In industrial department temperature sensor such as thermocouple, thermal resistance be a very common product be also must not
Can be less, it has small, flexible, high pressure resistant diameter, anti-vibration, thermal response fast, easy for installation and high reliability.
The larger thermometric place of vibrations, often the service life of temperature sensor is shorter, it is easy to cause precision to reduce or short interruption
Situations such as, and the probability that thermometer boss is damaged is just smaller, the frequency for changing temperature sensor is higher, it is therefore desirable to Yi Zhongneng
Be convenient for changing, it is cheap, can antidetonation temperature sensor
The content of the invention
The utility model is to provide for a kind of temperature sensor for facilitating core pulling, that the temperature sensor is changed is convenient, into
This is relatively low.
To achieve the above object, the technical solution of the utility model is：A kind of temperature sensor for facilitating core pulling, including
Thermometer boss, temperature sensor, holddown spring, lead, upper protection pipe, positioning pipe, terminal box, the temperature sensor is with drawing
Line is connected, and is formed and is furnished with holddown spring, the temperature sensor, lead, holddown spring and positioning pipe group outside temperature measuring point, lead
Into an entirety, and it is placed in thermometer boss and upper protection pipe, the terminal box is connected through a screw thread protection pipe.
The upper protection pipe is welded with six squares, the upper protection pipe cold end with terminal box junction passes through housing pin
Holddown spring is extruded, temperature sensor is close at the top of thermometer wrap pipe orifice.
The temperature sensor, lead and holddown spring and the overall of positioning pipe formation are inserted at upper protection pipe cold end screw thread
Enter at the top of thermometer boss, and be locked by the housing pin at upper protection pipe cold end.
Sheath is provided between the temperature sensor and thermometer boss.
The temperature sensor is thermoelectricity occasionally thermal resistance.
The beneficial effects of the utility model are：
Temperature sensor is connected with lead, forms temperature measuring point, is furnished with holddown spring outside lead, with temperature sensor shape
Into an entirety, one is to avoid lead damaged, the situation for short circuit occur, and two be in order to be able to allowing temperature sensor preferably to contact temperature
Degree meter sleeve bottom, makes thermal response speed accelerate.Because with leaded in holddown spring, if being not equipped with fixed structure,
In the larger situation of upper protection pipe orifice, it is easily bent, therefore is furnished with positioning pipe outside holddown spring, allows holddown spring will not be because
It is deformed greatly very much for endoporus.The endoporus of thermometer boss will be determined according to the size of sensor, it is impossible to too big, in order to avoid sensing
Device receives the power of the incoming holddown spring of housing pin and deformed after penetrating.Upper protection pipe uses steel-tube construction, with thermometer wrap
Pipe coordinates.Upper protection pipe is with welding six squares at terminal box cooperation, it is whole that sensor, lead, holddown spring and positioning pipe are formed
Body is inserted into bottom at upper protection pipe screw thread.Housing pin is locked at upper protection pipe again.The temperature sensor can be with
It is that thermocouple can also be thermal resistance, is made up of measurement head and extension lead.
When temperature sensor is during use, breaks down or measures inaccurate, it can directly unclamp and connect
Line box lid, extracts the entirety of temperature sensor, lead, holddown spring and positioning pipe composition out, it is not necessary to replace with out of terminal box
Protection pipe, not only facilitates but also can save expense.
Spring can allow temperature sensor to be close at the top of thermometer wrap pipe orifice so that thermal response speed accelerates；Spring for
Temperature sensor also has cushioning effect.
Brief description of the drawings
Fig. 1 is of the present utility model to facilitate core pulling arrangement of temperature sensor schematic diagram.
Embodiment
The utility model will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of temperature sensor for facilitating core pulling, including thermometer boss 1, temperature sensor 2, sheath
3rd, holddown spring 4, lead 5, upper protection pipe 6, positioning pipe 7, six squares 8, housing pin 9, terminal box 10.
Temperature sensor 2 is connected with lead 5, forms a kind of flexible temperature measuring point, is furnished with holddown spring 4 outside lead 5,
One side lead 5 belongs to soft type, and bending yardstick is big, and increase holddown spring 4 can guarantee that the perpendicularity of lead 5, is also avoided that and draws
Line 5 is directly exposed, and exocuticle is damaged, the short circuit phenomenon of temperature sensor 2 occurs.The upper cold end of protection pipe 6 is first welded with six squares 8,
It can tighten, then be connected with thermometer boss 1 prior to terminal box 10 after being welded.Connector cover is turned on, temperature sensor
2nd, lead 5 and holddown spring 4 penetrate lower mouth screw to the bottom of thermometer boss 1, because space is larger in upper protection pipe 6, compress
The diameter of spring 4 is small, can be rocked in upper protection pipe 6, temperature sensor 2 is damaged.Therefore in upper protection pipe 6 and holddown spring 4
Between increase positioning pipe 7, be fixed and clamped spring 4.Finally at the upper cold end of protection pipe 6, by housing pin 9 to holddown spring 4
Extruding, make the more preferable measurement end of contact thermometer sleeve pipe 1 of temperature sensor 2, its thermal response speed accelerates.
