Compartment temperature sensor with insulation sleeve
Technical field
The utility model relates to for thermometric protective device field, is specially a kind of compartment temperature sensor with insulation sleeve.
Background technology
Along with the progress of electronics technology, infotech becomes the main flow in people's life gradually.Three large bases of modern information technologies are information acquisition (being sensor technology), communication (being mechanics of communication) and information processing (being computer technology), and sensor especially temperature sensor belongs to the forward position highly sophisticated products of infotech.Temperature sensor is to utilize the temperature variant rule of various physical propertys of material a kind of sensor of temperature transition for electric weight, is the core of temperature measuring instrument.Temperature sensor is widely used in the occasion that needs monitoring temperature.But when using, must fix by temperature sensor, probe segment should avoid contacting other objects simultaneously, workplace for some vibrations, as the compartment in travelling, be the running of watch-dog, need to grasp in real time environment temperature, the compartment that travels often is among upheaval jolts, existing temperature sensor is difficult to fixedly secure, and rocks easily even comes off, and has affected to measure operation and measuring accuracy.
The utility model content
In order to overcome the defective of prior art, provide a kind of simple in structure, install firmly, the temperature measurement equipment strong to environmental suitability, the utility model discloses a kind of compartment temperature sensor with insulation sleeve.
The utility model reaches goal of the invention by following technical solution:
A kind of compartment temperature sensor with insulation sleeve, comprise temp probe, compensating wire be connected wire, the signal output part of temp probe is connected an end and is connected with compensating wire, the other end of compensating wire connects with an end that is connected wire, it is characterized in that: also comprise protective sleeve, protecting pipe and row wire terminal, protective sleeve is enclosed within outside the temp probe, one end of temp probe passes from protective sleeve, the lateral surface at temp probe middle part and the inwall of protective sleeve one end are fixed, the junction of temp probe and compensating wire is located in the protective sleeve, protecting pipe is enclosed within and connects outside the wire, the other end that connects wire is connected with row wire terminal after protecting pipe passes, row wire terminal is by base, conducting strip and buckle form, be embedded with conducting strip on the side of base, outside the side of one end protuberate basic unit of conducting strip, the other end of conducting strip be connected wire and connect, buckle is located on one group of relative lateral surface of base.
Described compartment temperature sensor with insulation sleeve, it is characterized in that: the length that temp probe exposes the protective sleeve part is 1/4~1/2 of temp probe total length, the length of temp probe and protective sleeve inwall fixed part is 1/4~1/2 of temp probe total length, and the lateral surface at temp probe middle part and the inwall of protective sleeve one end are selected and be adhesively fixed.
When the utility model uses, can be easily fixed to optional position in the compartment by protective sleeve; Buckle is used for the electrical connection with other equipment; Protective sleeve is connected temp probe, compensating wire and connection wire and is connected with protecting pipe; for preventing the interference to temperature survey and signal transmission; protective sleeve and protecting pipe be the two insulation and thermal insulation materials of electric heating all, make such as phenoplast, igelite, vinyon and rubber etc.
The beneficial effects of the utility model are: simple in structure, install firmly, and applied widely.

Embodiment
Below further specify the utility model by specific embodiment.
Embodiment 1
A kind of compartment temperature sensor with insulation sleeve, comprise temp probe 11, compensating wire 12, connect wire 13, protective sleeve 2, protecting pipe 3 and row wire terminal 4, as depicted in figs. 1 and 2, concrete structure is: the end that the signal output part of temp probe 11 is connected with compensating wire connects, the other end of compensating wire 12 connects with an end that is connected wire 13, protective sleeve 2 is enclosed within outside the temp probe 11, one end of temp probe 11 passes from protective sleeve 2, be adhesively fixed in the lateral surface at temp probe 11 middle parts and protective sleeve 2 one ends, the junction of temp probe 11 and compensating wire 12 is located in the protective sleeve 2, protecting pipe 3 is enclosed within and connects outside the wire 12, the other end that connects wire passes the rear connection of being connected with row wire terminal from protecting pipe 3, row wire terminal 4 is by base 41, conducting strip 42 and buckle 43 form, be embedded with conducting strip 42 on the side of base 41, outside the side of one end protuberate basic unit 41 of conducting strip 42, the other end of conducting strip 42 be connected wire 12 and connect, buckle 43 is located on one group of relative lateral surface of base 41.For preventing the interference to temperature survey and signal transmission, protective sleeve 2 and protecting pipe 3 be the two insulation and thermal insulation materials of electric heating all, make such as phenoplast, igelite, vinyon and rubber etc.
The length that temp probe 11 exposes protective sleeve 2 parts is 1/4~1/2 of temp probe 11 total lengths, and present embodiment gets 1/3; The length of temp probe 11 and protective sleeve 2 inwall fixed parts is 1/4~1/2 of temp probe 11 total lengths, and present embodiment gets 1/3.
When present embodiment uses, can be easily fixed to optional position in the compartment by protective sleeve 2, protective sleeve 2 is connected pair temp probe 11, compensating wire 12 and be connected wire and shield with protecting pipe.
