[0002] In the production process of a temperature sensor including wires, connecting the wires to the temperature sensor is a necessary processing step, which is usually completed with the cooperation of tooling. In the prior art, a thin plate is usually used as a wire arranging plate for fixing and arranging the wire harness of the temperature sensor, and square grooves are usually provided on the wire arranging plate to fix the wire harness of the temperature sensor. However, since the width of the square groove must be wider than the wire, the wire is prone to move in the groove, resulting in reduced production efficiency and decreased assembly precision.
[0003] Therefore, it is necessary to propose an improvement to overcome the defects of the prior art. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems in the prior art and provide a wire connection device for a temperature sensor with high assembly precision and small production error.
[0005] The technical solution of the utility model is as follows:
[0006] A wire connection device for a temperature sensor includes a bonding tooling, a metal substrate and a wire arranging plate arranged on the bonding tooling. Multiple groups of temperature sensor wire harnesses are arranged on the wire arranging plate. Each group of temperature sensor wire harnesses includes two wires. A limiting groove is arranged on the wire arranging plate corresponding to each group of temperature sensor wire harnesses. The limiting groove is in a W shape. The W-shaped limiting groove includes two concave portions and a middle convex portion separating the two concave regions. The middle convex portion of the W-shaped limiting groove extends into the middle interval region between the two wires of each group of temperature sensor wire harnesses, and the middle convex portion limits each group of temperature sensor wire harnesses. The two wires of each group of temperature sensor wire harnesses are respectively arranged in the two concave portions of the W-shaped limiting groove.

[0009] As a preferred technical solution, platform portions are arranged at the bottoms of the two concave portions. The platform portions are in contact with the wires.
[0010] As a further preferred technical solution, the width of the platform part is 0.8 to 1.0 times the diameter of the wire.
[0011] As a preferred technical solution, the wire arranging board is a fiberglass board with a thickness of 5 mm.
[0012] As a preferred technical solution, the depths of the two recessed parts are both 1.2 to 1.5 times the diameter of the wire.

[0014] A temperature sensor wire connection device of the present utility model is provided with a W-shaped limiting groove corresponding to the temperature sensor wire harness on the wire arranging board. The W-shaped limiting groove includes two recessed parts and a middle convex part separating the two recessed parts. The middle convex part extends into the middle interval area between two temperature sensor wires, and the two wires are respectively arranged in the recessed parts on both sides. Thereby, the wires can be more closely attached to the inside of the W-shaped limiting groove, reducing the movement of the wires in the groove, significantly improving the stability of wire fixing, reducing assembly errors caused by wire movement, and thus improving the overall production efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] The terms used in the embodiments of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0021] Depending on the context, the words "if", "when" as used herein may be interpreted as "when" or "when... " or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrase "if determined" or "if detected (stated condition or event)" may be interpreted as "when determined" or "in response to determining" or "when detected (stated condition or event)" or "in response to detecting (stated condition or event)".
[0022] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such a commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the said element.
[0023] As Figure 1 shown, it is a schematic diagram of a specific embodiment of a wire connection device for a temperature sensor of the present utility model. A wire connection device for a temperature sensor in this embodiment includes a bonding tooling 1, a metal substrate 2 and a wiring board 5 provided on the bonding tooling 1. A plurality of groups of temperature sensor wire harnesses 6 are fixedly arranged on the wiring board 5. A temperature sensor is provided on the metal substrate 2. The temperature sensor wire harness 6 is fixedly connected to the temperature sensor through the wire connection device for a temperature sensor in this embodiment. As Figure 3As shown, each group of temperature sensor wire harnesses 6 includes two wires 61. On the wire arranging board 5, a limiting groove is provided corresponding to each group of temperature sensor wire harnesses. The limiting groove is in a W shape. The W-shaped limiting groove includes two recessed portions 51 and an intermediate convex portion 52 that separates the two recessed portions 51. The intermediate convex portion 52 of the W-shaped limiting groove extends into the intermediate interval region between the two wires 61. The intermediate convex portion 52 limits the two wires 61 of the same group of temperature sensor wire harnesses 6, preventing the wires 61 from sliding or rolling in the limiting groove. The two wires 61 are fixed in the two recessed portions 51 on both sides of the intermediate convex portion 52. In a temperature sensor wire connection device of this embodiment, the design of the W-shaped limiting groove enables the wires to be fixed to the wire arranging board more tightly, reduces the movement of the wires on the wire arranging board, can significantly improve the stability of wire fixing, reduces assembly errors caused by wire movement, thereby reducing the time required for readjustment due to wire misalignment, and thus improving the overall production efficiency. The tight fixing effect of the W-shaped limiting groove reduces errors and rework during the production process, and improves the overall performance of the temperature sensor production line.
[0024] As a preferred solution, as Figure 2 shown, in a temperature sensor wire connection device of this embodiment, a substrate positioning pin 3 is provided on the metal substrate 2. The substrate positioning pin is provided corresponding to the temperature sensor wire harness 6, and is used to fixedly combine the temperature sensor wire harness 6 with the metal substrate 2, so as to facilitate the fixed connection between the temperature sensor wire harness 6 and the temperature sensor.
[0025] As Figure 1 shown, in a temperature sensor wire connection device of this embodiment, a wire arranging board positioning pin 4 is provided on the wire arranging board 5. The wire arranging board positioning pin 4 fixedly combines the wire arranging board 5 with the connecting tooling 1. By combining the fixed position of the wire arranging board 5 and the connecting tooling 1 through the wire arranging board positioning pin 4, it can ensure that the position of the temperature sensor wire harness 6 on the wire arranging board 5 is relatively fixed with respect to the metal substrate 2, and ensure the assembly accuracy.
[0026] As Figure 3 shown, in a temperature sensor wire connection device of this embodiment, a platform portion is provided at the bottom end of each of the two recessed portions 51. The recessed portion 51 is an inverted trapezoidal structure with a wider top and a narrower bottom; the platform portion contacts the wire 61 to better fix the wire 61. As a further preferred solution, the width of the platform portion is 0.8 to 1.0 times the diameter of the wire 61, avoiding wire movement caused by an overly wide recessed portion. In this embodiment, in order to ensure that the wire 61 can be completely accommodated in the recessed portion 51, the depth of the recessed portion 51 is 1.2 to 1.5 times the diameter of the wire 61. This depth can enable the wire to fully extend into the recessed portion, and can also enable the intermediate gap between the two wires to be fully combined with the intermediate convex portion 52, ensuring that the intermediate convex portion 52 is inserted into the intermediate interval gap between the two wires and plays a role in limiting the two wires.
[0027] In order to enable the flexible printed circuit board 5 to have sufficient mechanical strength and insulation performance, in this embodiment, the flexible printed circuit board 5 is made of a fiberglass board with a thickness of 5 mm.
[0028] In order to take into account the processing of the flexible printed circuit board 5 and the limiting function of the W-shaped limiting groove, in this embodiment, the included angle between the two outer sides of the W-shaped limiting groove is 60°, that is, the included angle between the sides of the two recessed parts away from the middle protruding part is 60°. During the processing, a high-precision numerical control machine tool or laser cutting technology can be used to process a W-shaped groove on the fiberglass board. Ensure that the accuracy during the processing is controlled within ±0.1 mm. Check the processed W-shaped groove to ensure that its size and shape meet the design requirements and there are no obvious burrs or defects.
[0029] A temperature sensor wire connection device of the present utility model is provided with a W-shaped limiting groove corresponding to the temperature sensor wire harness on the flexible printed circuit board. The W-shaped limiting groove includes two recessed parts and a middle protruding part separating the two recessed parts. The middle protruding part extends into the middle interval area between the two temperature sensor wires, and the two wires are respectively arranged in the recessed parts on both sides. Thereby, the wires can be more closely attached to the inside of the W-shaped limiting groove, reducing the movement of the wires in the groove, significantly improving the stability of wire fixing, reducing assembly errors caused by wire movement, and thus improving the overall production efficiency. A temperature sensor wire connection device of the present utility model can effectively reduce errors and rework during the production process and improve production efficiency. Therefore, a temperature sensor wire connection device of the present utility model has the advantages of high assembly accuracy, small production error, and high production efficiency.
[0030] The above is only a preferred embodiment of the present utility model and is not used to limit the scope of implementation of the present utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present utility model shall fall within the technical scope of the present utility model.
