[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Please refer to the attached document. Figures 1-5 This application provides a reinforcing component 100 for a flexible circuit board, which is used to strengthen the connection between the flexible circuit board 10 and the thermistor element 30.

[0033] Please refer to the attached document. Figures 1-5 In this invention, the reinforcing assembly 100 of the flexible circuit board includes a flexible circuit board 10, a reinforcing member 20, and a thermistor element 30. The flexible circuit board 10 has a first reinforcing position 11 and a second reinforcing position 12. The first reinforcing position 11 and the second reinforcing position 12 are arranged adjacent to each other. The reinforcing member 20 is connected to the flexible circuit board 10 and reinforces the flexible circuit board 10. The reinforcing member 20 is L-shaped. The reinforcing member 20 includes a first arm 21 and a second arm 22. The first arm 21 is arranged relative to the first reinforcing position 11 and is connected to the flexible circuit board 10 by adhesive 23. At this time, the first arm 21 is connected to the flexible circuit board 10 in the vertical direction. The second arm 22 is perpendicular to the first arm 21 and is located at... The upper side of the first arm 21; the second arm 22 is connected to the flexible circuit board 10 by filler adhesive 24, the filler adhesive 24 is connected to the second reinforcement position 12, and is connected to the side wall of the second arm 22 in the left and right direction; the thermistor element 30 is electrically connected to the flexible circuit board 10 and is located at the second reinforcement position 12; the filler adhesive 24 wraps the thermistor element 30 so that the thermistor element 30 can be connected to the flexible circuit board 10 in multiple directions through the reinforcement 20, thereby facilitating multi-directional reinforcement of the thermistor element 30, avoiding reinforcement of only one surface, preventing the flexible circuit board 10 and the thermistor element 30 from falling off due to external force collision, and improving the connection stability between the flexible circuit board 10 and the thermistor element 30.

[0034] Please refer to the attached document. Figures 1-5 In this utility model, the flexible circuit board 10 is provided with a first reinforcing position 11 and a second reinforcing position 12; the first reinforcing position 11 and the second reinforcing position 12 are arranged adjacent to each other.

[0035] The reinforcing member 20 is connected to the flexible circuit board 10 and reinforces the flexible circuit board 10, ensuring the strength of the flexible circuit board 10. The reinforcing member 20 is L-shaped. The reinforcing member 20 includes a first arm 21 and a second arm 22. The first arm 21 is arranged relative to the first reinforcing position 11 and is connected to the flexible circuit board 10 by adhesive 23, so that the reinforcing member 20 can be fixedly connected to the flexible circuit board 10 through the first arm 21. At this time, the first arm 21 is connected to the flexible circuit board 10 in the vertical direction. The second arm 22 is perpendicular to the first arm 21 and is located on the upper side of the first arm 21. The second arm 22 is connected to the flexible circuit board 10 by filler adhesive 24. The filler adhesive 24 is connected to the second reinforcing position 12 and is connected to the side wall of the second arm 22 in the left-right direction.

[0036] The thermistor element 30 is electrically connected to the flexible circuit board 10 to facilitate electrical conductivity between the thermistor element 30 and the flexible circuit board 10. The thermistor element 30 is located at the second reinforcement position 12. The filler adhesive 24 wraps the thermistor element 30 so that the thermistor element 30 can be connected to the flexible circuit board 10 in multiple directions through the reinforcement member 20. This facilitates multi-directional reinforcement of the thermistor element 30, avoids reinforcing only one surface, prevents the flexible circuit board 10 and the thermistor element 30 from falling off due to external impact, and improves the connection stability between the flexible circuit board 10 and the thermistor element 30.

[0037] Please refer to the attached document. Figures 1-5 In this invention, the reinforcing member 20 is arranged in a ring, forming a robust and continuous rigid frame. The cross-section of the reinforcing member 20 is L-shaped, which provides excellent bending and torsional stiffness. Filler 24 is embedded in the central cavity of the reinforcing member 20 and wraps around the thermistor element 30. The filler 24 fills the tiny gaps between the thermistor and the cavity of the reinforcing member 20, ensuring a tighter and more uniform thermal coupling between them, thereby improving the response speed and accuracy of the thermistor element 30.

[0038] Please refer to the attached document. Figures 1-3In this invention, the filler adhesive 24 and the adhesive 23 are distributed in different directions of the reinforcing member 20 and act on the adjacent side walls of the reinforcing member 20. The filler adhesive 24 and the adhesive 23 are connected in the horizontal direction to connect the stepped side walls of the reinforcing member 20 with height differences. This allows the reinforcing member 20 to be connected to the flexible circuit board 10 and the thermistor element 30 in different directions through the filler adhesive 24 and the adhesive 23. This facilitates the thermistor element 30 to be connected to the flexible circuit board 10 in multiple directions through the reinforcing member 20, thereby achieving multi-directional reinforcement of the thermistor element 30. This avoids reinforcing only one surface and prevents the flexible circuit board 10 and the thermistor element 30 from falling off due to external force collisions, thus improving the connection stability between the flexible circuit board 10 and the thermistor element 30.

[0039] Please refer to the attached document. Figures 1-5 In this utility model, the reinforcing member 20 is provided with a lower sidewall 25, a first inner sidewall 26, and a second inner sidewall 27; the first inner sidewall 26 and the second inner sidewall 27 have a height difference and form a corresponding stepped sidewall; the first inner sidewall 26 is located between the lower sidewall 25 and the second inner sidewall 27, and the lower sidewall 25 is directly opposite the first reinforcing position 11, so that the reinforcing member 20 can be connected to the first reinforcing position 11 through the lower sidewall 25, and the reinforcing member 20 can be connected to the thermistor element 30 through the first inner sidewall 26 and the second inner sidewall 27.

[0040] Please refer to the attached document. Figures 1-3 In this invention, the filler adhesive 24 does not extend beyond the upper sidewall of the reinforcing member 20 in the vertical direction. If the filler adhesive 24 is a conductive or semi-conductive formula, it may cause accidental bridging with adjacent pads and leads after overflowing; limiting the height can completely avoid this.

[0041] Please refer to the attached document. Figures 1-3 In this invention, the lower sidewall 25 of the thermistor element 30 is welded to the flexible circuit board 10 to form a low thermal resistance and low electrical resistance path. At the same time, the thermistor element 30 is fixed on the flexible circuit board 10, becoming the final bearing point for all subsequent forces. The peripheral sidewall of the filler adhesive 24 wraps the upper sidewall of the thermistor element 30 so that water and dust cannot seep into the thermistor element 30 from the side, while maintaining the original heat conduction path of the central cavity unchanged and not affecting the contact with the measured medium.

[0042] Please refer to the attached document. Figures 1-5 In this utility model, the reinforcing member 20 is a plastic part, which reinforces the flexible circuit board 10 and improves the strength of the flexible circuit board 10.

[0043] Please refer to the attached document. Figures 1-2In this utility model, the flexible circuit board 10 is provided with a main circuit support arm 13 and a branch circuit support arm 14. The branch circuit support arm 14 is disposed on one side of the main circuit support arm 13 and connected to the main circuit support arm 13. The branch circuit support arm 14 is provided with a first reinforcement position 11 and a second reinforcement position 12, and is reinforced by a reinforcement member 20 so that the reinforcement member 20 can be connected to the flexible circuit board 10 through the branch circuit support arm 14, thereby facilitating the strengthening of the branch circuit support arm 14.

[0044] Please refer to the attached document. Figures 1-2 In this invention, the main circuit support arm 13 and the branch circuit support arm 14 are integrally connected, which improves the connection strength between the main circuit support arm 13 and the branch circuit support arm 14 and ensures the connection stability between the main circuit support arm 13 and the branch circuit support arm 14.

[0045] Please refer to the attached document. Figures 1-2 In this invention, the circuit layer of the main circuit arm 13 is electrically connected to the circuit layer of the branch circuit arm 14 so that the main circuit arm 13 and the branch circuit arm 14 can conduct electricity.
