Sealed temperature sensor

Abstract

The invention relates to the technical field of sensors, in particular to a sealed temperature sensor. The sensor comprises a sensor body, wherein clamping blocks are arranged on the side walls of thesensor body and connected with sliding blocks through rotating rods; a first spring is arranged between every two rotating rods, an electric wire is connected above the sensor body, passes through asealing box and extends out of a mounting box, and a moving block is arranged in the sealing box and connected with one ends of sliding rods; the other ends of the sliding rods are connected with a sliding seat, and the sliding seat is connected with an arc-shaped plate outside the mounting box. According to the sealed temperature sensor, the four clamping blocks clamp the sensor body together toensure that the sensor body cannot fall off; by pulling the electric wire upwards to drive the moving block to move, the moving block can adjust the movement of the sliding rods; through the movementof the sliding rods, the arc-shaped plate can be adjusted to compress the electric wire; the arc-shaped plate can only move in a one direction, and therefore, the electric wire cannot be loosened after being locked. The pressure change in the mounting box caused by the random movement of the electric wire is avoided, and the poor contact between the electric wire and the sensor body caused by excessive extraction of the electric wire can be avoided by adopting buckles.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a sealed temperature sensor. Background technique [0002] A temperature transducer is a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument, and there are many varieties. According to the measurement method, it can be divided into two categories: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into two types: thermal resistance and thermocouple. In recent years, the process of my country's industrial modernization and the continuous high-speed growth of the electronic information industry have driven the rapid rise of the sensor market. As an important category of sensors, temperature sensors account for more than 40% of the total sensor demand. The temperature sensor is a semiconductor d...
