Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a wire harness connector assembly and a battery pack. Background Technology

[0002] The battery pack is the core power source of an electric vehicle. It consists of battery modules, which need to be connected to a control circuit board. The control circuit board collects the cell parameters (such as current, voltage, and temperature) of each cell within the battery module, thereby monitoring the operating status of each cell. Typically, a wiring harness connector is used to connect the control circuit board to the battery module, ensuring electrical connectivity between the two systems.

[0003] To save space occupied by the control circuit board, two control circuit boards are usually stacked during actual assembly. When the wiring harness connector is plugged into the two layers of control circuit boards, the operator may easily plug the connector that should be plugged into the upper control circuit board into the lower control circuit board, resulting in incorrect wiring harness connector insertion. This can lead to short circuit faults in the battery pack, increasing safety hazards and costs.

[0004] Therefore, there is an urgent need to design a wire harness connector assembly and a battery pack to solve the above technical problems. Utility Model Content

[0008] A wire harness bracket, wherein multiple rows of wire harness slot units are provided on the wire harness bracket, each row of wire harness slot units has multiple wire harness slots, and the wire harness slots are directly opposite the plug-in interface on the control circuit board.

[0009] The first wire harness is provided in multiple configurations, with each wire harness corresponding to a wire harness slot. The end of each first wire harness is snapped into a wire harness slot, and the end of each first wire harness is provided with a connector, which is configured to be plugged into the corresponding connector.

[0010] As an optional technical solution for a wire harness plug-in assembly, the wire harness groove has an accommodating portion and a limiting portion that are connected to each other. The width M of the accommodating portion is greater than the width N of the limiting portion, and the limiting portion is in communication with the edge of the wire harness bracket.

[0011] As an optional technical solution for a wire harness plug-in assembly, the wire harness slot unit is configured in four rows, and the wire harness bracket is rectangular; wherein, two rows of the wire harness slot units are symmetrically arranged about the horizontal axis of the wire harness bracket, and the other two rows of the wire harness slot units are symmetrically arranged about the vertical axis of the wire harness bracket, and the horizontal axis and the vertical axis are perpendicular to each other.

[0012] As an optional technical solution for a wire harness plug-in assembly, the wire harness plug-in assembly further includes a second wire harness, wherein the end of the first wire harness facing away from the plug-in is connected to the second wire harness, and the end of the second wire harness facing away from the first wire harness is used to connect to the battery module.

[0013] As an optional technical solution for wire harness plug-in assembly, both the first wire harness and the second wire harness are fitted with protective sleeves on their outer periphery.

[0014] As an optional technical solution for wire harness plug-in assembly, multiple wire harness brackets are provided, and each wire harness bracket corresponds to a control circuit board.

[0018] The second objective of this invention is to provide a battery pack that enables foolproof connection between the wiring harness connector and multiple control circuit boards, thereby improving connection efficiency and reducing safety hazards.

[0019] To achieve this objective, the present invention adopts the following technical solution:

[0020] This utility model provides a battery pack, including a battery module, multiple control circuit boards, and a wiring harness plug-in assembly as described in any of the above optional technical solutions. The wiring harness plug-in assembly is connected to both the battery module and the control circuit boards.

[0021] The beneficial effects of this utility model include at least the following:

[0022] This utility model provides a wire harness plug-in assembly for plugging in multiple control circuit boards. The assembly mainly includes a wire harness bracket and a first wire harness. The wire harness bracket has multiple rows of wire harness slot units, each row having multiple wire harness slots, which face the plug-in interfaces on the control circuit boards.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] Example 1

[0043] This embodiment provides a wire harness plug-in assembly to prevent mistaken connections between the wire harness plug-in assembly and multiple control circuit boards, thereby improving plug-in efficiency and reducing safety hazards.

[0044] like Figures 1-3 As shown, the wire harness connector assembly is used to connect multiple control circuit boards 100. The wire harness connector assembly mainly includes a wire harness bracket 10 and a first wire harness 20. The wire harness bracket 10 has multiple rows of wire harness slot units, each row having multiple wire harness slots 11, which face the connectors 110 on the control circuit boards 100. Multiple first wire harnesses 20 are provided, each corresponding to a wire harness slot 11. The ends of the first wire harnesses 20 are engaged within the wire harness slots 11, and each end of the first wire harness 20 is provided with a connector 21 configured to connect to the corresponding connector 110.

[0045] Based on the above design, in this embodiment, the wire harness bracket 10 is provided, and the wire harness bracket 10 is provided with wire harness slots 11 that correspond one-to-one with the plug-in interfaces 110 on the control circuit board 100. The wire harness slots 11 can engage the end of the first wire harness 20, thereby constraining and limiting the first wire harness 20. Since the wire harness slots 11 are directly opposite the plug-in interfaces 110 on the control circuit board 100, the plug-in piece 21 of the end of the first wire harness 20 engaged in the wire harness slots 11 can be accurately plugged into the corresponding plug-in interfaces 110. This not only improves the plugging efficiency but also reduces the occurrence of plugging errors by operators. It achieves the foolproof function of plugging the wire harness plugging assembly into multiple control circuit boards 100, reduces safety hazards, and saves costs.

[0046] like Figures 2-3 As shown, in this embodiment, the wire harness slot 11 has an accommodating portion 111 and a limiting portion 112 connected to each other. The width M of the accommodating portion 111 is greater than the width N of the limiting portion 112, and the limiting portion 112 is through the edge of the wire harness bracket 10. The accommodating portion 111 is designed to accommodate the first wire harness 20, and the limiting portion 112 is designed to limit the first wire harness 20, preventing the first wire harness 20 from becoming loose from the wire harness slot 11, ensuring insertion efficiency and accuracy, and achieving a foolproof insertion effect.

[0047] Since the connector 21 and the first wire harness 20 are assembled before the material arrives, in this embodiment, the limiting part 112 is designed to be connected to the edge of the wire harness bracket 10. This allows the first wire harness 20 to be squeezed by the limiting part 112, causing the limiting part 112 to deform, thereby allowing the first wire harness 20 to be accommodated in the accommodating part 111, thus completing the assembly of the first wire harness 20 and the wire harness bracket 10.

[0048] For example, such as Figure 1 As shown, in this embodiment, there is one wire harness bracket 10 and two control circuit boards 100, which are stacked together. The wire harness bracket 10 is located on one side of the two stacked control circuit boards 100. The single wire harness bracket 10 reduces the number of parts, lowers the processing difficulty of the wire harness bracket 10, and improves the integration and overall integrity of the wire harness connector assembly.

[0049] like Figures 2-3 As shown, in this embodiment, the wire harness slot units are arranged in four rows, and the wire harness bracket 10 is rectangular. Two rows of wire harness slot units are symmetrically arranged about the horizontal axis of the wire harness bracket 10, and the other two rows are symmetrically arranged about the vertical axis of the wire harness bracket 10. The horizontal and vertical axes are perpendicular to each other. This allows for the arrangement of more wire harness slots 11 on the limited-size wire harness bracket 10, accommodating control circuit boards 100 with more connectors 110, thus improving flexibility and applicability. The horizontal axis of the wire harness bracket 10 is along... Figure 3 Extending along the X-axis direction, the longitudinal axis of the wire harness bracket 10 is along... Figure 3 It extends along the Y-axis.

[0050] like Figure 1 As shown, the wiring harness connector assembly also includes a second wiring harness 30. The end of the first wiring harness 20 facing away from the connector 21 is connected to the second wiring harness 30. The end of the second wiring harness 30 facing away from the first wiring harness 20 is used to connect to the battery module (not shown in the figure). Specifically, the end of the second wiring harness 30 is connected to the flexible printed circuit board (FPC) in the battery module. The FPC is connected to the battery cell, thereby enabling the wiring harness connector assembly to collect data such as voltage, current, and temperature of the battery cell to monitor the operating status of each battery cell.

[0051] Optionally, in this embodiment, protective sleeves are provided on the outer periphery of both the first wire harness 20 and the second wire harness 30. The protective sleeves are made of insulating material to protect the first wire harness 20 and the second wire harness 30 and prevent leakage or short circuit.

[0052] Optionally, the wire harness bracket 10 in this embodiment is a non-metallic component. For example, the wire harness bracket 10 is a polycarbonate component or a fiberglass component. On the one hand, this saves costs and reduces the weight of the wire harness connector assembly, achieving lightweight design; on the other hand, the non-metallic wire harness bracket 10 improves safety, reduces safety hazards, and minimizes or avoids short circuits.

[0053] This embodiment also provides a battery pack, which includes a battery module (not shown in the figure), multiple control circuit boards 100, and the aforementioned wiring harness plug-in assembly. The wiring harness plug-in assembly is connected to both the battery module and the control circuit boards 100.

[0054] Specifically, the battery module includes an FPC, and the aforementioned wiring harness connector is connected to the FPC in the battery module. The FPC is used to collect the electrical parameters (such as current, voltage, temperature, etc.) of each cell in the battery module and transmit these parameters to the wiring harness connector. Since the wiring harness slots 11 on the wiring harness bracket 10 correspond one-to-one with the connectors 110 on the control circuit board 100 and are directly opposite each other, the connector 21 at the end of the first wiring harness 20, which is engaged in the wiring harness slot 11, can be accurately inserted into the corresponding connector 110. This not only improves the insertion efficiency but also reduces the possibility of insertion errors by operators. It achieves the foolproof function of connecting the wiring harness connector to multiple control circuit boards 100, reduces safety hazards, and saves costs.

[0055] Example 2

[0056] like Figures 4-6As shown, this embodiment provides a wire harness plug-in assembly. The main difference from Embodiment 1 is that in this embodiment, multiple wire harness brackets 10 are provided, and each wire harness bracket 10 corresponds to a control circuit board 100. In other words, this embodiment designs the wire harness brackets 10 as separate units, with each control circuit board 100 corresponding to one wire harness bracket 10. This allows for flexible adjustment of the distance between two adjacent wire harness brackets 10 to accommodate control circuit boards 100 of different thicknesses.

[0057] In this embodiment, there are two wire harness brackets 10 and two control circuit boards 100, and the two wire harness brackets 10 are arranged symmetrically, and the two control circuit boards 100 are stacked. This can improve the working efficiency of the wire harness plug-in assembly and the two control circuit boards 100 and reduce plug-in errors.

[0058] The remaining structures of the wire harness plug-in assembly in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.

[0059] Obviously, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.

[0060] Note that in the description of this specification, the references to terms such as "some embodiments," "other embodiments," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model.
