As shown in fig. 1 and fig. 2, a temperature detecting device 100 provided in the embodiment of the present disclosure is used for cooperating with a bus bar 200, and includes: flexible circuit board 110, temperature sensor 120, and insulating stiffener 130.
The flexible circuit board 110 includes a first surface 110a facing away from the bus bar 200, and a second surface 110b facing toward the bus bar 200.
The temperature sensor 120 is disposed on the first face 110a of the flexible circuit board 110. As an example, the temperature sensor 120 is connected to a trace in the flexible circuit board 110, i.e., the temperature sensor 120 is electrically connected to the flexible circuit board 110. Alternatively, the temperature sensor 120 is fixed on the flexible circuit board 110 by means of reflow soldering. In this way, the detection signal output by the temperature sensor 120 based on the ambient temperature is output through the flexible circuit board 110. Moreover, compared with the method of soldering the nickel sheet and the temperature sensor in the related art, the processing technology for fixing the temperature sensor 120 on the flexible circuit board 110 is simpler and more convenient.
In one embodiment, as shown in fig. 3, the temperature sensing device 100 further includes a packaging assembly 140. The packaging member 140 is wrapped on the temperature sensor 120 to fix the temperature sensor 120 on the first surface 110a of the flexible circuit board 110.
Alternatively, the package 140 is resin glue, and the package 140 is covered on the temperature sensor 120 through a glue dropping process. In this way, the connection stability of the temperature sensor 120 and the flexible circuit board 110 is improved by the package 140. In addition, the package member 140 has moisture-proof, insulating and shock-absorbing effects, and ensures the stability and safety of the temperature detection device.
The insulating reinforcement plate 130 is disposed on the second face 110b of the flexible circuit board 110. As an example, the insulating stiffener 130 is attached to the second surface 110b of the flexible circuit board 110 by an adhesive. Optionally, the insulating stiffener 130 is a Polyimide (PI) plate, and has a thickness of 0.1mm to 0.5 mm.

The stability of the flexible circuit board 110 is increased by the insulating reinforcing plate 130, the flexible circuit board 110 and the bus bar 200 are prevented from shifting, and the temperature sensor 120 is stably arranged on the bus bar 200.
Furthermore, the wear resistance of the flexible circuit board 110 is also improved by the insulating reinforcing plate 120. Because the temperature sensor 120 is electrically connected to the flexible circuit board 110, a conductive connector disposed along the thickness direction of the flexible circuit board 110 may be selected to connect the temperature sensor 120 and the flexible circuit board 110. The hard material of the conductive connecting member may affect the local wear resistance of the flexible circuit board 110. In this case, the insulation reinforcing plate 130 reinforces a part of the flexible circuit board 110, and prevents abrasion at the connection of the temperature sensor 120 and the flexible circuit board 110.
The temperature detection apparatus 100 provided by the embodiment of the present disclosure detects the temperature of the bus bar 200 through the temperature sensor 120 located on the bus bar 200. When the temperature detection device is installed on the bus bar, the insulating reinforcing plate 130 on the flexible circuit board 110 is attached to the bus bar, so that the whole method is convenient to operate, and the installation cost is low.
In one embodiment, as shown in FIG. 3, the insulating stiffener 130 is disposed corresponding to the temperature sensor 120. Here, "correspond" means that the projection of the insulating reinforcement plate 130 on the second surface 110b of the flexible circuit board 110 has an overlapping portion with the projection of the temperature sensor 120 on the first surface 110a of the flexible circuit board 110. In this way, the insulation reinforcing plate 130 is fully ensured to effectively improve the stability and the wear resistance of the flexible circuit board 110.
Preferably, the projection area of the insulating reinforcement plate 130 on the second surface 110b of the flexible circuit board 110 is larger than the projection area of the temperature sensor 120 on the first surface 110a of the flexible circuit board 110. In this way, the active area of the insulating stiffener 130 is optimized, and the flexible circuit board 110 is further prevented from being displaced with respect to the bus bar 200.

In one embodiment, as shown in fig. 4, the temperature detecting device includes at least two temperature sensors 120, and the insulating reinforcing plates 130 are disposed in one-to-one correspondence with the temperature sensors 120. In this way, temperature detection is performed at different positions of the bus bar 200 by the plurality of temperature sensors 120, and the temperature detection accuracy is improved.
In this case, the flexible circuit board 110 includes a first portion 111 and at least two second portions 112. Wherein the first portion 111 is disposed along a length direction of the bus bar 200. The first portion 111 is provided with a data interface 113, and the data interface 113 and the temperature sensor 120 are electrically connected through traces of the flexible circuit board 110.

Also, the second portion 112 includes a first face 110a facing away from the busbar 200, and a second face 110b facing toward the busbar 200. That is, the temperature sensor 120 and the insulating reinforcement plate 130 are disposed on the second portion 112.
In this way, the second portion 112 of the flexible circuit board 110 is disposed above the bus bar 200, and the first portion 111 is disposed beyond the bus bar 200 and along the length direction of the bus bar 200.
