Description
Technical Field
The present disclosure relates generally to the field of switchgear technology, and more particularly, to a temperature sensor.
Background
Temperature is an important safety factor for a switchgear or other electrical cabinet. Overload due to grid faults, poor mechanical connection of the busbar, the cable, and changes in the contact state of the switchgear can all cause abnormal increases in temperature, which can be observed by temperature sensors. On the other hand, a "smart grid" has been proposed for several years, and a smart device with a sensing system of thermal, electrical and even mechanical characteristics is critical to the realization that a "smart grid" provides sufficient data.
Fig. 1 is a schematic diagram of a conventional wireless temperature sensor 10. The sensor has an embedded temperature probe 102 and a sensor housing 104. The mounting plate 1042 of the sensor housing 104 has a mounting aperture 1044 therein. The temperature probe 102 is inserted into the sensor housing through the mounting hole 1044. A fastening member is used inside the sensor housing 104 to fix the temperature probe 102, preventing the temperature probe 102 from falling out of the mounting hole of the mounting base plate.
Currently, the design of the fastening means between the temperature probe and the mounting plate is generally of the following three types.
The first design uses a snap spring to fasten the probe, which is compact in size, but requires a very large effort to install a small snap spring in a very limited space.
The second design is to fasten the probe with a nut, which makes the installation easy, but requires more space due to the need to install a nut.
The third design uses a rubber ring to fasten the probe, which is compact in size and easy to install, but in the case of high axial forces or long-term high-temperature use, the rubber ring risks falling off the groove on the probe.

In view of the above, the present utility model proposes a temperature sensor with an embedded temperature probe, wherein the temperature probe can be quickly and conveniently mounted on a sensor housing.
Fig. 2 is a schematic cross-sectional view of a temperature sensor 20 according to one embodiment of the utility model.
As shown in fig. 2, the temperature sensor 20 according to the present utility model includes: the temperature probe 202 and the sensor housing 204, the sensor housing 204 includes a mounting base plate 2042, the mounting base plate 2042 includes a mounting through hole 2044, and the mounting through hole 2044 is used for mounting the temperature probe 202.
Fig. 3 is a partially enlarged schematic view of the mounting through hole 2044 in the mounting base plate 2042. Two opposite limiting members 2046 are disposed at one end of the mounting through hole 2044 near the inner side of the sensor housing 2042, each limiting member 2046 includes a limiting groove 20462 and a limiting boss 20464 located on each of two sides of the limiting groove 20462, and two mounting guide grooves 2048 inside the mounting through hole 2044 are respectively formed between two adjacent limiting bosses 20464 of the two limiting members 2046.
Fig. 4 is an enlarged schematic view of the temperature probe 202. The temperature probe 202 includes a spacing end 2022 and a temperature measuring end 2024, the spacing end 2022 including two opposing flanges 20222. During normal operation of the temperature sensor, the two flanges 20222 of the temperature measuring probe 202 are respectively clamped in the two limiting grooves 20462 of the mounting through hole 2044, the limiting boss 20464 on two sides of each limiting groove is used for preventing the flanges 20222 from rotating out of the limiting grooves, and the temperature measuring end 2024 is exposed outside the sensor housing and is used for contacting an object to be measured to measure temperature.
Wherein, when the temperature probe 202 is mounted to the sensor housing 204, two flanges 20222 of the temperature probe 202 are inserted into the sensor housing 204 along two fitting guide grooves 2048 inside the mounting through hole 2044 of the sensor housing 204, respectively, until the flanges 20222 just exceed the limit boss 20464, so that the temperature probe 202 is rotated by 90 degrees, the two flanges fall into and are locked in the two limit grooves.
Specifically, in the present utility model, a person skilled in the art may set the width of the flange and the width of the limit groove as needed so that the flange may be caught in the limit groove, and correspondingly set the width of the limit boss so that the width of the formed assembly guide groove may accommodate the insertion of the flange into the sensor housing along the assembly guide groove. The temperature measuring probe is characterized in that the limit groove is slightly lower than the inner surface of the mounting bottom plate, the limit boss is slightly higher than the inner surface of the mounting floor, the assembly guide groove and the limit groove are approximately spaced by 90 degrees in the mounting through hole, so that when the flange exceeds the limit boss, the temperature measuring probe rotates by 90 degrees, the two flanges just fall into the limit groove respectively, and the limit bosses on the two sides can prevent the flange from rotating out of the limit groove by misoperation.
The temperature probe can be conveniently installed in the sensor housing by a simple operation of pressing and rotating the temperature probe.
Preferably, a spring 206 is sleeved outside the temperature probe 202, and the height of the temperature probe 202 and the parameters of the spring 206 are set such that when the temperature probe 202 and the spring 206 are inserted together into the end position in the mounting through hole 2044 of the sensor housing 204, the two flanges 20222 of the temperature probe 202 just exceed the limit boss 20464.

Preferably, the circumference of the temperature measuring end is larger than the circumference of the temperature measuring probe body.
As can be seen from fig. 4, the temperature measuring end 2024 is larger than the circumference of the main body of the temperature measuring probe by one turn, so that the temperature measuring probe can be prevented from being completely inserted into the mounting through hole, because the temperature measuring end is exposed to the outside of the sensor housing to contact the measured object for temperature measurement.
Preferably, the surface of the temperature measuring end 2024 is provided with a cross-shaped groove 20242.
Fig. 5 is a schematic illustration of a cross-shaped groove provided on the surface of the temperature measuring tip 2024.
The surface of the temperature measuring end is provided with a special cross-shaped groove structure, and a special tool is required to be used for installation during installation, so that the temperature measuring probe can be prevented from falling out of the sensor shell due to misoperation.
