Technical Field

[0001] The utility model relates to the field of sensors, in particular to a temperature sensor which is easy to assemble. Background Art

[0002] In some designs of existing temperature sensors, the induction hook and the connecting wire are connected by welding. In order to prevent the connection from contacting the external metal shell and causing a short circuit, the connection is often sealed by glue filling, thereby achieving the purpose of preventing short circuit. However, the design and processing process of this type of temperature sensor is relatively complicated. Therefore, a temperature sensor with a simple structure, easy processing, good short circuit prevention effect, and easy assembly is needed. Utility Model Content

[0003] The main purpose of the utility model is to provide a temperature sensor which has a simple structure, is easy to process and has a good short-circuit prevention effect and is easy to assemble.

[0004] The utility model provides a temperature sensor which is easy to assemble, comprising a sensor body, an outer shell and an inner protective shell;

[0005] The sensor body includes a sensing head and a connecting wire, wherein two connecting pins of the sensing head are connected to the connecting wire by welding, and the inner protective shell is made of a non-conductive material, and the inner protective shell is sleeved on the outer side of the connection between the sensing head and the connecting wire;

[0006] The outer shell is sleeved on the outer side of the inner protective shell, the top of the sensing head extends from the top of the inner protective shell and contacts the outer shell, and the sensor body detects the external temperature through the outer shell.

[0007] Preferably, the inner protective shell is made of flexible plastic.

[0008] Preferably, a limiting protrusion bent inwardly is provided on the inner side of the top of the inner protective shell.

[0009] Preferably, the outer shell is provided with an external connection hole for connection and fixation.
