Surface temperature sensor

Technical Field

The utility model relates to the technical field of sensors, in particular to a surface temperature sensor.

Background

The temperature of the existing engines, motors and the like is higher in the use process, so that a temperature sensor is needed to monitor the temperature in real time, and the influence of the overhigh temperature on the service life of the machine and safety accidents are avoided.

The existing surface temperature sensor has large whole volume and complex structure, and is fixed on the surfaces of an engine and a motor by adopting fixing modes such as welding, clamping buckles, screws and the like, so that the disassembly and the assembly are inconvenient.

Disclosure of Invention

In order to solve the problems, the utility model provides the surface temperature sensor which has the advantages of simple structure, convenient manufacture, flexible adjustment and wide application range.

The utility model is realized by the following technical scheme:

the utility model provides a surface temperature sensor, includes the cable conductor and the sensor main part that links to each other with the cable conductor, the sensor main part includes casing, PCB board and thermistor, casing one end has can supply power cable male first cavity and the second cavity that is linked together with first cavity, PCB board, thermistor set up respectively in the second cavity, and the PCB board links to each other with the cable conductor, and thermistor links to each other with the PCB board, second cavity one end runs through the casing and fills epoxy, the mounting hole has been seted up to the other end that the cable conductor was kept away from to the casing.

In order to be convenient for fix the cable conductor, prevent simultaneously that the cable conductor from being pressed when fixed, the cover is equipped with the copper pipe sheath between first cavity inner wall and the cable conductor, be provided with the holding screw that is used for compressing tightly copper pipe sheath and cable conductor on the casing.

In order to realize quick assembly disassembly, a third cavity communicated with the mounting hole is formed in the other end, far away from the cable, of the shell, one end of the third cavity penetrates through the shell, and a magnetic ring is fixed in the third cavity to serve as another fixing mode of the utility model.

The beneficial effects of the utility model are as follows: the surface temperature sensor has the advantages of simple integral structure, small volume, convenient assembly, strong universality and wider application range, and can be fixed by adopting three fixing modes of screw fixing, magnetic ring fixing and screw matching magnetic ring fixing in cooperation with the mounting hole and the magnetic ring.
