Abstract

The invention discloses a temperature sensor and an assembling method thereof, and the method comprises the following steps: S1, packaging a temperature sensing part: welding two groups of pins of a temperature sensing element, and carrying out the sealing packaging of the temperature sensing element and the welding points of the temperature sensing element and the two groups of pins, so as to form a temperature sensing head; s2, conducting wire treatment: stripping insulating layers of two conducting wire terminals in the cable, and exposing conductors at the end parts of the two conducting wire terminals; s3, conducting wires, enabling the two pins to be tightly attached to the two conductors in a one-to-one correspondence mode and to be sleeved with sheaths respectively, enabling the two sheaths to be insulated, and then pressing the sheaths to enable the pins in the sheaths to be tightly attached to the conductors; s4, sleeve wrapping: inserting the sheath, the temperature sensing head and the end part of the cable into a sleeve with one closed end; and S5, sealant sealing is conducted, specifically, sealant is injected into the casing pipe, and the sealant fills gaps in the casing pipe and overflows to the open end of the casing pipe. The temperature sensing element is stably connected with the conductor, and short circuit and short circuit phenomena of the temperature sensor in use can be effectively avoided.

Description

technical field [0001] The present application relates to the field of temperature control sensors, in particular to a temperature sensor and an assembly method thereof. Background technique [0002] Temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. 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. It is widely used in color TV, computer color monitor, switching power supply, water heater, refrigerator, kitchen equipment, air conditioner, automobile and other fields. With the rapid development of new energy vehicles, the requirements for temperature sensors applied to automotive electronic systems are also more stringent. [0003] The Chinese patent with the application number CN201310354379.1 in the related...
