Abstract
Description
Technical Field
[0001] This utility model belongs to the field of integrated busbar support technology, specifically relating to an integrated busbar support with wire fixing function and an integrated busbar using the integrated busbar support. Background Technology
[0002] In the field of new energy power and energy storage battery technology, to ensure the safe use of battery modules, integrated busbars are used to collect the operating data of the battery module cells. Compared with FPC integrated busbars, wire harness integrated busbars have certain advantages in terms of cost, signal transmission, and maintenance. In existing wire harness integrated busbars, the wires are bundled and wound into a wire harness using cloth tape or felt tape, and then fixed to the bracket with cable ties. This fixing method has the following drawbacks: First, the height and position of the wound wires cannot be controlled, which is not convenient for designing the length of each wire and also brings inconvenience to the subsequent welding and fixing; Second, after the tape is wrapped tightly, the wires are affected by the stress at the fixing point, and the branches will bend or curl up at any angle or direction, resulting in a messy appearance and failing to ensure the consistency of mass production; Third, the cable ties are easily damaged by excessively tight binding or prolonged use, leading to poor insulation and withstand voltage. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an integrated busbar bracket with wire fixing function.
[0004] To achieve the above objectives, this utility model discloses an integrated busbar bracket with wire fixing function, including a wiring board and a first mounting plate and a second mounting plate located on both sides of the wiring board, wherein the first mounting plate and the second mounting plate are used to install the guide components of the integrated busbar;
[0005] The wiring board is provided with a U-shaped wire buckle. The U-shaped wire buckle includes a first protrusion and a second protrusion erected on the wiring board. The first protrusion and the second protrusion are spaced apart to form a wire groove. The width of the wire groove is greater than the diameter of the wire. The free end of the first protrusion and / or the free end of the second protrusion extends to one side of the wire groove. The distance between the free ends of the first protrusion and the second protrusion is less than the diameter of the wire.
[0006] Preferably, the difference between the distance between the free end of the first protrusion and the free end of the second protrusion and the diameter of the wire is 0.2mm to 0.35mm.
[0007] Preferably, the free end of the first protrusion and / or the free end of the second protrusion is an arc surface.
[0008] Preferably, the wiring board has grooves on both sides of the root of the first protrusion and / or on both sides of the root of the second protrusion.
[0009] Preferably, the groove is a through groove.
[0010] Preferably, there are multiple U-shaped wire buckles, which are arranged side by side to form a wire buckle array.
[0011] Preferably, the free ends of the two protrusions on both sides of the wire strip buckle are arranged facing each other, and the free ends of all other protrusions extend to the two adjacent wire grooves.
[0012] Preferably, one end of the wiring board is the cable inlet, and the cable inlet is provided with the cable tray buckle.
[0013] Preferably, the wiring board is provided with a relief groove, which serves as a venting channel for the venting structure of the battery module cell.

[0015] An integrated busbar includes an integrated busbar support, multiple flow guides disposed on the integrated busbar support, and several wires. Each wire has a collection part at its end, and a collection part is connected to a corresponding flow guide. The integrated busbar support is any of the above-mentioned integrated busbar support with wire fixing function, and each wire is clipped into a corresponding U-shaped wire buckle.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model discloses an integrated busbar bracket with a U-shaped wire clip on the wiring board. The U-shaped wire clip includes a first protrusion and a second protrusion erected on the wiring board. The first and second protrusions are spaced apart to form a wire groove. The width of the wire groove is greater than the diameter of the wire, which provides sufficient width to accommodate the wire without applying force to the groove. This avoids problems such as difficulty in wire control, design issues, production difficulties, and easy wire damage caused by fixing methods such as adhesive tape. The free ends of the first and / or the second protrusions extend towards one side of the wire groove. The distance between the free ends of the first and second protrusions is less than the diameter of the wire.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] An integrated busbar, see Figures 1-2 It includes an integrated busbar support 1, multiple current guides 2 disposed on the integrated busbar support 1, and several wires 3. The current guides are used to connect the battery cells in series and in parallel. Each wire has a collection part 31 at its end. Each collection part is connected to a corresponding current guide. This is the existing structure of the existing wire harness type integrated busbar, which will not be described in detail here.
[0025] The main improvement of this embodiment compared to the prior art lies in the structure of the integrated busbar support 1. Specifically, the integrated busbar support 1 includes a wiring board 11 and a first mounting plate 12 and a second mounting plate 13 located on both sides of the wiring board 11. The first mounting plate 12 and the second mounting plate 13 are used to install the guide components of the integrated busbar. The wiring board 11 is provided with U-shaped wire clips 111. The U-shaped wire clips 111 include a first protrusion 112 and a second protrusion 113 erected on the wiring board 11. The first protrusion 112 and the second protrusion 113 are spaced apart to form wire grooves 114. The width of the wire grooves 114 is greater than the diameter of the wire. Each wire is secured in a corresponding U-shaped wire clip 111. The above-mentioned wire grooves 114 are designed so that the wire grooves 114 have sufficient width to accommodate the wires without applying force to the wire grooves 114. This avoids the problems of difficult wire control, design, production difficulties, and easy wire damage caused by fixing methods such as adhesive tape. The free ends of the first protrusion 112 and / or the free ends of the second protrusion 113 extend toward one side of the wire groove 114. Specifically, in this embodiment, the free ends of both the first and second protrusions 113 extend toward one side of the wire groove 114. The distance between the free ends of the first protrusion 112 and the free ends of the second protrusion 113 is less than the diameter of the wire. In this way, after the wire is inserted into the wire groove 114, the wire can be confined within the wire groove 114, and the wire can ultimately be fixed on the wiring board 11.
[0026] In this embodiment, the wiring board 11, the first mounting plate 12, the second mounting plate 13, the first protrusion 112 and the second protrusion 113 are integrally formed by injection molding. Of course, it is not limited to this integrally formed structure; it can also be a detachable structure, such as a snap-fit structure.
[0027] In this embodiment, the difference between the distance between the free end of the first protrusion 112 and the free end of the second protrusion 113 and the diameter of the wire is 0.2mm to 0.35mm. This can reliably hold the wire in the wire groove 114, while avoiding damage to the wire due to the small opening of the wire groove 114.
[0028] To further protect the wire from scratches, the free ends of the first protrusion 112 and the second protrusion 113 are rounded.
[0029] In this embodiment, the wiring board 11 is provided with grooves 115 on both sides of the root of the first protrusion 112 and the root of the second protrusion 113. By providing grooves 115 at the root of the first protrusion 112 and the second protrusion 113, the elasticity of the protrusion is increased, and it has better deformation ability. At the same time, it is relatively less prone to fatigue during multiple wire-clamping processes, which can improve the service life of the structure.
[0030] The groove 115 is a through groove, which not only gives the first protrusion 112 and the second protrusion 113 the best elasticity, but also facilitates manufacturing (injection molding).
[0031] In practice, different locations on the wiring board 11 require different types of wiring channels 114. For example, near the guide member, only one corresponding wiring channel 114 needs to be provided to fix a single cable connected to the guide member. However, at the cable inlet 116 of the wiring board 11, multiple cables will enter, requiring a row of cables to be secured. Therefore, the cable inlet 116 of the wiring board 11 is provided with multiple U-shaped cable clips 111, which are arranged side-by-side to form a cable tie 117, thus securing a row of cables. Compared to simply providing multiple U-shaped cable clips 111 individually, this cable tie design also results in a more compact overall structure.
[0032] In addition to the two outermost protrusions of the cable tray buckle 117, the middle protrusion of the cable tray buckle 117 needs to fix the wires of the two adjacent cable grooves 114. Therefore, the free ends of the two protrusions on both sides of the cable tray buckle 117 are arranged facing each other, and the free ends of all other protrusions extend to the two adjacent cable grooves 114.
[0033] In this embodiment, the wiring board 11 is provided with a relief groove 118, which is a venting channel for the venting structure of the battery module cell.
[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
