Description

Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a temperature sensor. Background Technology

[0002] Existing temperature sensors are widely used in various heating devices, such as milk warmers, kettles, steam humidifiers, and meat grinders. These appliances often process relatively high power and require grounding wires for user protection. While grounding wires are usually installed separately, temperature sensors are often directly attached to the internal housing for measurement accuracy, which actually meets the requirements for grounding wire installation. Combining the grounding wire with the temperature sensor can reduce the number of components, lower structural complexity, reduce assembly complexity, and increase assembly speed. Utility Model Content

[0003] The main objective of this invention is to provide a temperature sensor that combines a ground wire with a temperature sensor, thereby reducing the number of components, lowering structural complexity, reducing assembly complexity, and increasing assembly speed.

[0004] This utility model proposes a temperature sensor, including a sensor housing, a thermistor, a connecting terminal, and a connecting latch;

[0005] The thermistor is disposed inside the sensor housing. The two connecting pins of the thermistor are respectively connected to the connecting terminal through the first connecting line and the second connecting line. The sensor housing is provided with housing connecting bosses on both sides. One end of the connecting latch is connected to the housing connecting boss, and the other end of the connecting latch is connected to one end of the third connecting line. The other end of the third connecting line is connected to the connecting terminal. The third connecting line is a ground wire.

[0006] Preferably, the housing connecting boss is provided with a connecting boss connecting hole, and the connecting boss connecting hole is connected to the external structure by screws, so that the temperature sensor can be connected and installed on the external structure.

[0007] Preferably, a potting layer is provided on the inner side of the sensor housing, and the thermistor is connected and disposed inside the sensor housing through the potting layer.

[0008] Preferably, it also includes a ground ring, which is connected to the connection terminal via a fourth connecting line, the fourth connecting line being a ground wire, thereby achieving grounding effectiveness through the ground ring.

[0009] The beneficial effects of the temperature sensor of this utility model are as follows:

[0010] 1. By setting a ground ring and a third connection line that serves as the ground wire and connects to the sensor housing, the ground wire can be integrated with the temperature sensor, which can reduce the number of components and reduce structural complexity.

[0011] 2. By using a potting layer to connect and install the thermistor inside the sensor housing, the measurement capability of the thermistor is ensured while also improving the waterproof effect of the temperature sensor. Attached Figure Description

[0018] A thermistor is disposed inside the sensor housing 1. A potting layer is provided inside the sensor housing 1, and the thermistor 2 is connected and disposed inside the sensor housing 1 through the potting layer. The two connecting pins of the thermistor 2 are connected to the connecting terminal 3 via a first connecting wire 7 and a second connecting wire 8, respectively. The first connecting wire 7 and the second connecting wire 8 are the live wire and the neutral wire, respectively.

[0019] The sensor housing 1 has housing connection bosses 11 on both sides. One end of the connecting latch 4 is connected to the housing connection boss 11, and the other end of the connecting latch 4 is connected to one end of the third connecting line 8. The other end of the third connecting line 8 is connected to the connecting terminal 3. The third connecting line 8 is the ground wire. The third connecting line 8 provides leakage protection for the temperature sensor and the electrical components connected to the temperature sensor, which is generally an internal heating cavity.

[0020] The ground ring 5 is connected to the connection terminal 3 through the fourth connection line 9. The fourth connection line 9 is a grounding wire, and the ground ring achieves the effect of grounding.
