Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0041] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0042] In order to solve the technical problem that the existing integrated busbar assembly needs to increase an injection support for separate fixing for the NTC module 3, thereby causing the production cost of the entire integrated busbar to rise, the embodiments of the present application provide an integrated busbar assembly for fixing the NTC module 3.

[0043] The specific structure of the integrated busbar assembly for fixing the NTC module 3 provided by the embodiments of the present application will be described in detail below. According to the drawings shown, the specific structure of the integrated busbar assembly includes a blister support plate 1, a flexible circuit board 2, an NTC module 3 and a sticking piece 4.

[0044] One end surface of the blister support plate 1 is provided with a placement area 11, the flexible circuit board 2 is arranged in the placement area 11, the other end surface of the blister support plate 1 is provided with a positioning groove 12, part of the flexible circuit board 2 extends into the positioning groove 12, and the NTC module 3 is arranged in the positioning groove 12 and fixed to the end surface of the flexible circuit board 2. By providing the placement area 11 for assembling the flexible circuit board on the end surface of the blister support plate 1, a predetermined mounting position is provided for the flexible circuit board, and it is ensured that the flexible circuit board 2 can be accurately assembled in the specified position of the blister support plate 1.

[0045] According to Figures 2-5 As shown, part of the flexible circuit board 2 extends into the positioning groove 12, and the NTC module 3 is arranged on the extended part of the flexible circuit board 2. The positioning groove 12 plays an accurate positioning role on the extended part of the flexible circuit board 2 and the NTC module 3.

[0046] In order to ensure that the extension part of the NTC module 3 and the flexible circuit board 2 can be fixedly installed, and prevent the NTC module 3 and the extension part of the flexible circuit board 2 from being loose, one end surface of the adhesive piece 4 is adhered to the end surface of the flexible circuit board 2 away from the NTC module 3, and the other end surface of the adhesive piece 4 is adhered to the inner groove wall of the positioning groove 12.

[0047] Specifically, since the two end surfaces of the adhesive piece are respectively a first adhesive surface and a second adhesive surface, the first adhesive surface and the second adhesive surface have certain adhesion, and therefore the first adhesive surface of the adhesive piece is used to be adhered to the end surface of the flexible circuit board 2 away from the NTC module 3, and the second adhesive surface of the adhesive piece is adhered to the inner groove wall of the positioning groove 12, so that the extension part of the flexible circuit board 2 and the whole NTC module 3 can be fixed, and the condition that the whole NTC module 3 is prone to shaking or falling off due to external force or vibration of the whole busbar assembly can be prevented. Therefore, the NTC module 3 can be fixed without the help of additional fasteners such as screws and bolts, the whole assembly process is simplified, and a support frame for fixing the NTC module 3 is not additionally required.

[0048] As can be seen from the above, the traditional busbar assembly needs to increase an injection molded support for separately fixing the NTC module 3, and the adhesive piece is used to fix the NTC module 3 in the embodiment of the utility model, so that the whole production process is simplified, and the production cost is also reduced.

[0049] In some optional embodiments, the adhesive piece 4 is double-sided adhesive foam, that is, a first adhesive surface of the double-sided adhesive foam is used to adhere to the flexible circuit board 2, and a second adhesive surface of the double-sided adhesive foam is used to adhere to the inner groove wall of the positioning groove 12. Since the first adhesive surface and the second adhesive surface of the double-sided adhesive foam are coated with pressure-sensitive adhesive (PSA), when the first adhesive surface of the double-sided adhesive foam is adhered to the flexible circuit board 2, strong intermolecular forces (such as van der Waals forces) are generated, so that the first adhesive surface of the double-sided adhesive foam and the flexible circuit board 2 can be fixedly adhered.

[0050] It should be noted that the double-sided adhesive foam is made of polyethylene or polyurethane material. Since the inside of the double-sided adhesive foam is full of small and closed pores, it can absorb external impact force and uniformly disperse the force, so that the NTC module 3 is protected by certain buffering and shock absorption, and stress concentration is avoided to cause damage or looseness of the NTC module 3.

[0051] According to Figures 6-7 As shown in FIG. 1, in some specific embodiments, the flexible circuit board 2 is provided with a first positioning hole 21; and the end surface of the suction plastic support plate 1 assembled with the flexible circuit board 2 is provided with a first positioning column 13, and the first positioning column 13 is arranged in the first positioning hole 21.

[0052] Specifically, when the flexible circuit board 2 is assembled on the placement area 11 of the blister support plate 1, the first positioning column 13 of the blister support plate 1 is inserted into the first positioning hole 21, and at this time, the outer side wall of the first positioning column 13 is in interference fit with the side wall of the first positioning hole 21, so that the outer side wall of the first positioning column 13 is tightly fitted with the side wall of the first positioning hole 21, which can effectively prevent the flexible circuit board 2 from loosening or moving due to vibration or other external forces. Through the cooperation of the first positioning hole 21 and the first positioning column 13, on the one hand, the assembly precision of the flexible circuit board 2 and the blister support plate 1 can be improved, and on the other hand, the shaking of the flexible circuit board can be effectively prevented.

[0053] According to Figures 8-9 As shown in FIG. 2, in some specific embodiments, the flexible circuit board 2 includes a first flexible circuit board 22 and a second flexible circuit board 23; the first flexible circuit board 22 is arranged on the placement area 11, the second flexible circuit board 23 is arranged in the positioning groove 12, and a flexible circuit board 24 in a curved shape is arranged between the first flexible circuit board 22 and the second flexible circuit board 23; and the NTC module 3 is arranged on the second flexible circuit board 23.

[0054] Specifically, since the first flexible circuit board 22 is arranged on the blister support plate 1, the second flexible circuit board 23 is arranged in the positioning groove 12, and the NTC module 3 is arranged on the second flexible circuit board 23, the overall structure is more compact. The flexible circuit board between the first flexible circuit board 22 and the second flexible circuit board 23 is in a curved shape, and the curved flexible circuit board 24 can form various bending and folding shapes, so that the first flexible circuit board 22 and the second flexible circuit board 23 can be assembled at different positions according to different assembly requirements without the aid of additional fixing members.

[0055] It should be noted that the first flexible circuit, the curved flexible circuit board 24 and the second flexible circuit board 23 are integrally formed, thereby forming a complete circuit frame.

[0056] According to Figures 6-7 As shown in FIG. 2, in some specific embodiments, the blister support plate 1 is concave and has a plurality of installation cavities 14, and each installation cavity 14 is provided with an aluminum bar 15; and the aluminum bar 15 is connected with the flexible circuit board 2 through a nickel sheet 152.

[0057] Specifically, each mounting cavity 14 of the blister support plate 1 is used to accommodate each aluminum bar 15, so as to ensure that each aluminum bar 15 is difficult to fall off or displace during operation; the shape and size of the mounting cavity 14 can be set according to the shape of the aluminum bar 15, so as to ensure that the aluminum bar 15 can be stably fixed in the specified position. Since the nickel sheet 152 has good electrical conductivity and is used as a conductive connecting piece, each aluminum bar 15 is connected to the flexible circuit board (the first flexible circuit board 22) through the nickel sheet 152, so that the aluminum bar 15 and the flexible circuit board (the first flexible circuit board 22) realize the transmission of current and signal.

[0058] It should be noted that the nickel sheet 152 can be fixedly connected with the flexible circuit board 2 by welding or crimping, so as to prevent the two from being faulty due to poor electrical connection or poor contact.

[0059] According to Figures 6-7 As shown in further embodiments, the mounting cavity 14 is provided with a second positioning column 141, and the aluminum bar 15 is provided with a second positioning hole 151, and the second positioning column 141 is arranged in the second positioning hole 151.

[0060] Specifically, when each aluminum bar 15 is assembled in each mounting cavity 14, the second positioning column 141 arranged in the mounting cavity 14 is arranged in the second positioning hole 151, and at this time, the outer side wall of the second positioning column 141 is in interference fit with the side wall of the second positioning hole 151, so that the outer side wall of the second positioning column 141 is tightly combined with the side wall of the second positioning hole 151, which can effectively prevent the whole aluminum bar 15 from loosening or displacing due to vibration or other external force. Through the cooperation of the second positioning hole 151 and the second positioning column, on the one hand, the position accuracy during assembly of the aluminum bar 15 can be improved, on the other hand, during assembly of the aluminum bar 15, the second positioning column 141 only needs to be arranged in the second positioning hole 151 until the aluminum bar 15 abuts against the bottom surface of the mounting cavity 14, and then the assembly of the aluminum bar 15 is completed, and on the other hand, the shaking of the aluminum bar 15 can be effectively prevented.

[0061] According to Figure 1 As shown in some specific embodiments, the blister support plate 1 penetrates a plurality of explosion-proof valve observation holes 16.

[0062] Specifically, the plurality of explosion-proof valve observation holes 16 are spaced apart by a certain distance, so that the production personnel can check the running state or whether there is an abnormal condition of other components inside the busbar assembly through each explosion-proof valve observation hole 16, which is convenient for preliminary judgment and fault positioning, and timely maintenance of the inside of the busbar assembly.

[0063] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
