[0022] The following describes a wiring harness connector for a temperature sensor according to the present invention, using embodiments thereof, with reference to the accompanying drawings. In the following description, numerous specific details are set forth to provide a more comprehensive understanding of the present invention for those skilled in the art. However, it will be apparent to those skilled in the art that the present invention may be implemented without some of these specific details. Furthermore, it should be understood that the present invention is not limited to the specific embodiments described. Rather, any combination of the following features and elements may be considered for implementing the present invention, regardless of whether they relate to different embodiments.

[0023] Figure 1 A perspective view of a temperature sensor 100 using a wire harness clamping device 1 according to an embodiment of the present invention is shown. In order to illustrate the internal structure of the temperature sensor, the cover of the sensor housing is omitted. Figure 2 for Figure 1 FIG2 is an exploded view of a temperature sensor 100 in FIG2 , wherein the temperature sensor 100 includes a temperature sensor housing 10. As can be seen from the figure, in one embodiment of the present invention, a wiring harness clamping device 1 for the temperature sensor 100 includes a wiring harness terminal 11 and a receiving structure 12 disposed within the sensor housing 10. The wiring harness 20 can be fixedly connected to the temperature sensor by snap-fitting the wiring harness terminal 11 and the receiving structure 12.

[0024] See also Figure 3 and Figure 4 In a preferred embodiment of the wiring harness clamping device 1, the wiring harness terminal 11 includes a pair of hollow seals 3 and a pair of conductive terminal parts 4. Each terminal part 4 has a first end 41 and a second end 42 opposite to the first end. The first end 41 is configured as a first crimping portion, which is suitable for connecting the hollow seal 3 to the terminal part 4. The terminal part 4 also includes a second crimping portion 43 adjacent to the first crimping portion, and the wiring harness 20 extends through the hollow seal 3 and is fixedly connected and electrically connected to the terminal part 4 through the second crimping portion 43. In a preferred embodiment, the seal 3 is made of rubber material. Advantageously, the terminal part 4 also includes a hook-shaped snap-fit portion 44 arranged near the second end 42, and the hook-shaped snap-fit portion is in the shape of a barb, that is, facing the direction of the seal 3. In this embodiment, since the terminal part 4 is made of copper sheet, the hook-shaped snap-fit portion has a certain elasticity.

[0025] In the above-described embodiment of the present invention, the wiring harness terminal 11 is configured to include a pair of seals, a pair of terminal components, and a pair of wiring harnesses connected to the terminal components. This configuration is particularly suitable for temperature sensors using thermocouple principles. However, those skilled in the art will appreciate that the wiring harness terminal can alternatively be configured to include a single seal, a single terminal component, and a single wiring harness. This configuration is also suitable for other types of sensors and is also within the scope of this application.

[0026] See also Figure 5 and Figure 6 , shows a receiving structure 12 according to a preferred embodiment of the present invention. As can be seen from the figure, the receiving structure 12, which is to snap-fit with the wiring harness terminal 11, includes a first through-hole 50 extending through the side wall 5 of the sensor housing 10, a first rib 6 and a second rib 7 disposed on the inner side of the side wall 5, and a second through-hole 60 and a third through-hole 70 extending through the first rib. The first through-hole 50, the second through-hole 60, and the third through-hole 70 are aligned with one another, i.e., arranged along the same straight line. In a preferred embodiment, the first and second ribs are parallel to the side wall. As a result, after the wiring harness terminal 11 is inserted into the sensor housing 10 through the first through-hole 50, the second through-hole 60, and the third through-hole 70, the seal 3 is positioned within the first through-hole 50 through an interference fit. The hook-shaped snap-fit portion 44, due to its elasticity, is able to pass through the first and second through-holes and then securely snap-fit between the first and second ribs 6 and 7 due to its own elastic restoring force.

[0027] See again Figure 6 The temperature sensor 100 further includes a printed circuit board 8 and a sensor terminal 9 . When the wiring harness terminal 11 is inserted into the sensor housing, the sensor terminal 9 is inserted into the terminal component 4 of the wiring harness terminal 11 , thereby electrically connecting the terminal component 4 to the printed circuit board 8 .

[0028] In the embodiment of the temperature sensor 100 shown in the present invention, see again Figure 1 and Figure 5 , which includes three wire harness clamping devices 1, two on the left and one on the right, to connect three sets of wire harnesses 20 to the temperature sensor. It should be understood that according to the specific requirements of the sensor, other numbers of wire harness clamping devices can be provided to connect other numbers of wire harnesses, which are also covered by the scope of this application.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, the present invention is not limited thereto. Any combination, change, and modification made by any person skilled in the art without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
