Description
Technical Field
[0001] This utility model relates to the field of temperature sensor technology, specifically to temperature sensors. Background Technology
[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety. They can be broadly classified into two categories based on the measurement method: contact and non-contact. Based on the characteristics of the sensor materials and electronic components, they are further divided into resistance temperature detectors (RTDs) and thermocouples.
[0003] For example, the announcement number CN222505639U describes a temperature sensor, which includes a base and a mounting end at the front end of the base. A cavity is formed inside the mounting end, and a probe is fixedly mounted at the lower end of the cavity by a hollow bracket. The upper end of the probe extends into the cavity, and the lower end extends out of the hollow bracket.
[0004] The aforementioned application, without increasing the length of the sensor, creates a medium space outside the probe, allowing the probe to fully contact the measured medium and increase the effective heat transfer of the measured medium, ensuring that the probe can respond quickly and fully to changes in the medium temperature. However, the temperature sensor needs to be completely removed and replaced after damage, and the wiring also needs to be disassembled and rewired. This is very inconvenient to operate when located in a narrow area, resulting in insufficient ease of use. Therefore, the market urgently needs to develop a temperature sensor to help people solve the existing problems. Utility Model Content

This makes it very inconvenient to operate when it is located in a narrow space, resulting in insufficient ease of use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature sensor, including a temperature sensor body and a fixed electrical connector, wherein the fixed electrical connector is fixed to the installation position of the temperature sensor, a quick-release connector is provided below the temperature sensor body, a first electrode plate is provided above the fixed electrical connector, a second electrode plate is provided below the quick-release connector, the first electrode plate and the second electrode plate are electrically connected in contact, the temperature sensor body is electrically connected to the second electrode plate, and a terminal block is fixedly installed on one side of the fixed electrical connector.
[0007] The above technical solution involves installing a fixed power base at the desired location for the temperature sensor, using a fixed method and connecting it to the power source. The temperature sensor body is then installed onto the fixed power base, and the connection between the temperature sensor body and the fixed power base is achieved through a quick-release mechanism. The quick-release connector is inserted above the fixed power base, and two electrode plates are used for contact and power connection. This eliminates the need for power connection and disassembly during installation and removal, making it more convenient to replace the temperature sensor. It is suitable for use in confined spaces, improving ease of use.

[0012] In a preferred embodiment, the present invention can be further configured such that: a coupling seat is fixedly installed below the quick-release connector, a contact rod is fixedly installed inside the coupling seat, a detection probe is provided below the coupling seat, and the detection probe is electrically connected when it contacts the contact rod.
[0013] Through the above technical solution, the contact rod is used to connect the temperature sensor body and the detection probe with electricity.

[0015] The above technical solution utilizes the coupling seat and detection probe to achieve a quick-release connection of the detection probe. After the detection probe surface is oxidized, only the detection probe needs to be replaced, thus eliminating the need to replace all sensors, thereby reducing consumables. Furthermore, the connection method is simple and reliable, making it more convenient to use.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
