DETAILED DESCRIPTION

[0043] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0044] The present application provides a mounting structure of a temperature sensor, which is used for mounting and connecting the temperature sensor 20 to the connecting end 111 of the flexible circuit board 10. In the present application, the base 30 is used for mounting the temperature sensor 20 and the conductor 40. The bent part 41 of the conductor 40 is clamped in the accommodating groove 31, and the conductor 40 is pressed against the bottom wall of the groove 32 by the pressing part 70. The conductor 40 is further bent upwards to form the folding part 43. The gap 44 below the folding part 43 is used for inserting the connecting end 111. By inserting the inserting part 531 into the inserting groove 343, the clamping part 52 is clamped in the clamping groove 341, so as to realize the clamping connection of the base 30 and the cover plate 50. The folding part 43 is pressed downwards by the abutting part 80 on the cover plate 50, so that the oxidation-proof layer 60 on the connecting end 111 is attached to the transverse part of the pressing part 70. The mounting structure does not need FPC reflow soldering, and can also realize the mounting of the temperature sensor 20 on the flexible circuit board 10. The construction process is simpler, and the production cost is reduced.

[0045] The mounting structure of the temperature sensor 20 will be described below with reference to the drawings.

[0046] Referring to Figure 1 and Figure 2 In the present embodiment, a mounting structure of a temperature sensor 20 is used for mounting and connecting the temperature sensor 20 to the connecting end 111 of the flexible circuit board 10. The mounting structure comprises: a hole formed in the insulating layer of the connecting end 111, through which the wire layer of the flexible circuit board 10 is partially exposed to form an exposed part; an oxidation-proof layer 60 arranged above the exposed part, which can conduct electricity; a base 30 for mounting the temperature sensor 20; a conductor 40 mounted on the base 30 and connected with the temperature sensor 20, which can conduct electricity; the connecting end 111 is mounted on the base 30, and the oxidation-proof layer 60 is attached to the conductor 40; a cover plate 50 clamped and connected to the base 30 corresponding to the connecting end 111, so as to clamp and fix the connecting end 111 between the base 30 and the cover plate 50.

[0047] The anti-oxidation layer 60 effectively prevents the copper from being exposed to air and being oxidized, and has electric conductivity. The clamping connection of the base 30 and the cover plate 50 is used to achieve detachable connection of the connecting end 111 and the temperature sensor 20, facilitating later maintenance and replacement. The connecting end 111 is fastened between the base 30 and the cover plate 50, so as to ensure that the conductor 40 and the anti-oxidation layer 60 are tightly attached, and the transmission of the electric signal is ensured. Compared with the existing FPC reflow soldering process, the manufacturing process of the installation structure is simple, and the manufacturing cost is low.

[0048] Referring to Figure 5 , Figure 6 and Figure 8 , in a specific embodiment, the bottom surface of the base 30 is provided with a receiving groove 31, and the temperature sensor 20 is located in the receiving groove 31. The top surface of the base 30 is provided with a groove 32, and the base 30 is provided with a communication groove 33 communicating with the groove 32 and the receiving groove 31. The conductor 40 is plate-shaped and has elasticity. The conductor 40 is placed on the bottom wall of the groove 32, and is bent at the connection between the groove 32 and the communication groove 33 and extends into the communication groove 33 to form a bent portion 41. The bent portion 41 is bent at the connection between the communication groove 33 and the receiving groove 31 and extends on the bottom wall of the receiving groove 31 and is connected with the temperature sensor 20. The connecting end 111 is located above the conductor 40 at the groove 32.

[0049] The temperature sensor 20 is installed in the receiving groove 31 of the bottom surface of the base 30, and the conductor 40 is installed in the receiving groove 31 of the top surface of the base 30. The bent portion 41 extends into the communication groove 33 and then extends on the bottom wall of the receiving groove 31.
