Description

Technical Field

[0001] The utility model relates to the field of temperature sensors, in particular to an oil-proof temperature sensor housing. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. It is divided into two types according to the measurement method: contact and non-contact. The contact type measures the liquid to be measured through a temperature measuring tube. The resistance value of the temperature measuring tube will change according to the temperature change of the temperature measuring tube. The resistance value can be directly converted into a numerical value for observation.

[0003] When using a temperature sensor to measure oil, it usually needs to be in contact with the oil for a long time. The oil can easily penetrate into the temperature sensor through the gaps on both sides of the temperature sensor housing and the connection between the temperature sensor housing and the cable. The electronic components inside the temperature sensor are soaked by the oil, causing the temperature sensor to become abnormal and damaged during use.

[0004] Therefore, it is necessary to develop an oil-proof temperature sensor housing to solve the above technical problems. Utility Model Content

[0008] As an improvement of the above scheme, a clamping block is also included, and the second semicircular extrusion ring and the first semicircular extrusion ring are respectively provided with a first clamping groove and a clamping block, and the first semicircular extrusion ring and the second semicircular extrusion ring are clamped together through the first clamping groove and the clamping block.

[0009] As an improvement to the above solution, a connecting plate is further included, and the connecting plate is fixedly connected to the sides of the first semicircular extrusion ring and the second semicircular extrusion ring that are away from each other.

[0010] As an improvement of the above solution, a clamping plate is further included, a second clamping groove is provided on a side of the first protective shell close to the second protective shell, a clamping plate is fixedly connected to a side of the second protective shell close to the first protective shell, and the first protective shell and the second protective shell are sealed and clamped together through the clamping plate and the second clamping groove.

The supporting shell is installed on one side of the display, the mounting frame is fixedly connected to the supporting shell, the fan is installed on the side of the mounting frame close to the display, and the heat conducting plate is installed on the side of the display close to the fan.

[0013] As an improvement of the above solution, a sealing gasket is further included. A sealing gasket is arranged at the joint between the first protective shell and the second protective shell.

[0014] Beneficial effects: 1. When assembling the temperature sensor housing, the first protective shell and the second protective shell are sealed by the clamping plate and the second clamping groove, thereby preventing oil from penetrating into the temperature sensor from both sides when the temperature sensor is in use.

The display 1 is installed on the first protective shell 2 and the second protective shell 3 together. A mounting seat 4 is installed below the first protective shell 2 and the second protective shell 3. A temperature measuring tube 5 is installed below the seat 4, and the temperature measuring tube 5 is electrically connected to the display 1. A placement ring 6 is slidably arranged in the first protective shell 2 and the second protective shell 3. A placement groove 601 is provided in the placement ring 6. A rubber ring 7 is installed in the placement ring 6. A fixing ring 8 is fixedly connected to the mounting seat 4, and the fixing ring 8 slides between the first protective shell 2 and the second protective shell 3. A first semicircular extrusion ring 9 and a second semicircular extrusion ring 10 are sleeved on the mounting seat 4.
