Description

Technical Field

[0001] This utility model relates to the field of wire harness isolation plate technology, specifically a wire harness isolation plate assembly structure. Background Technology

[0002] In the battery casing, the wire harness separator is a key functional component used to optimize the layout of the electrical system and ensure the safe operation of the battery. The wire harness separator in the battery casing is a plate (mostly made of insulating material) installed inside the battery module or battery pack. Its main function is to separate conductive components (such as aluminum busbars and cables) from the battery casing and cells to prevent short circuits or wear.

[0003] In existing technologies, aluminum busbars are installed on wire harness isolation plates by welding or bolting. Laser welding of the aluminum busbar to the nickel sheet on the wire harness isolation plate is strong, but it cannot be disassembled, making subsequent maintenance inconvenient. The aluminum busbar is connected to the isolation plate by silver-plated bolts and anti-loosening washers, which is detachable and convenient for maintenance and replacement, but requires tools to operate, which is relatively inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a wire harness isolation plate assembly structure, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire harness isolation plate assembly structure, comprising an isolation plate body and multiple aluminum busbar mounting grooves formed on the surface of the isolation plate body. The multiple aluminum busbar mounting grooves are linearly symmetrically distributed. Limiting protrusions are fixedly connected to the inner walls on both sides of each aluminum busbar mounting groove. Multiple blocks are fixedly connected to the surface of the isolation plate body. Each pair of blocks is used in combination. A clamping component is rotatably arranged between the two blocks in the same group. The other end of the clamping component is engaged with the limiting opening formed on the surface of the isolation plate body.

[0008] Preferably, the clamping assembly includes a clamping strip and a rotating shaft fixedly embedded at one end of the clamping strip.

[0013] (III) Beneficial Effects

[0014] This utility model provides a wire harness isolation plate assembly structure, which has the following beneficial effects:

[0015] 1. In this utility model, during installation, the aluminum strip is first slightly bent so that both ends are inserted below the limiting protrusion.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a wire harness isolation plate assembly structure, including an isolation plate body 1 and multiple aluminum busbar mounting grooves 101 opened on the surface of the isolation plate body 1. The multiple aluminum busbar mounting grooves 101 are linearly symmetrically distributed. Limiting protrusions 2 are fixedly connected to the inner walls on both sides of the aluminum busbar mounting grooves 101. The top of the limiting protrusions 2 is rounded (e.g., R0.3mm) to reduce the resistance when the aluminum busbar is inserted. Multiple stops 3 are fixedly connected to the surface of the isolation plate body 1. Every two stops 3 form a group for cooperative use. There is a gap between the two stops 3 in the same group. A clamping component is rotatably arranged between the two stops 3 in the same group. The other end of the clamping component is engaged with the limiting opening 105 opened on the surface of the isolation plate body 1.

[0025] Slightly bend the aluminum strip so that both ends of the aluminum strip are inserted below the limiting protrusion 2, so that the entire aluminum strip is located inside the aluminum strip mounting groove 101, achieving initial limiting. Then, operate the clamping component to clamp the middle of the aluminum strip.

[0026] When the aluminum busbar is subjected to a small external force and undergoes elastic deformation (not exceeding the material's elastic limit), it can return to its original shape after the external force disappears; therefore, the aluminum busbar can return to its original shape after being placed in the aluminum busbar mounting groove.

[0027] See Figures 4 to 5 Specifically, the clamping assembly includes a clamping strip 4 and a rotating shaft 5 fixedly embedded at one end of the clamping strip 4. The rotating shaft 5 is rotatably inserted between two stops 3 in the same group. The other end of the clamping strip 4 has a through and horizontally arranged mounting hole 401. The mounting hole 401 has an elastic locking structure inside. The inner sidewalls on both sides of the limiting port 105 have slots 104.

[0028] The clamping strip 4 is in direct contact with the surface of the aluminum busbar. The contact surface of the clamping strip 4 is sprayed with a silicone rubber coating (thickness 0.3mm-0.5mm) or impregnated with epoxy resin for insulation treatment; or an insulating gasket (such as polyimide film) is installed between the clamping strip 4 and the aluminum busbar.

[0029] At the same time, a chamfer should also be provided at the inlet of the aforementioned card slot 104 to ensure that the card receiving ball 8 can be moved out of the card slot 104 more smoothly.

[0030] See Figures 4 to 5 A base block 6 is fixedly connected to the middle position inside the mounting hole 401. Springs 7 are fixedly connected to both ends of the base block 6. A snap-fit ​​ball 8 is fixedly connected to the other end of the spring 7. When the end of the clamping strip 4 is located inside the limiting port 105, the snap-fit ​​ball 8 snaps into the slot 104.

[0031] During installation, the aluminum strip is first slightly bent so that both ends are inserted below the limiting protrusion 2. Then, the entire aluminum strip is positioned inside the aluminum strip mounting groove 101, achieving initial positioning. Next, the clamping strip 4 is rotated so that one end of the clamping strip 4 rotates into the limiting port 105. When the locking ball 8 moves to the locking groove 104, under the elastic thrust of the spring 7, the locking ball 8 is locked into the locking groove 104, thus pressing and fixing the middle part of the aluminum strip. This application can quickly realize the installation of the aluminum strip without any auxiliary tools, and the installation can be completed by hand.

[0032] The aluminum strip can also be quickly disassembled. First, pull the clamping strip 4 to separate it from the aluminum strip. At this time, the clamping strip 4 rotates. Then, squeeze the aluminum strip with your fingers from the heat dissipation port 102 to separate the end of the aluminum strip from the limiting protrusion 2, thereby achieving quick disassembly.

[0033] See Figure 5 The top opening of the limiting port 105 is provided with an angled angle 103.

[0034] The purpose of setting the angle 103 is to match the receiving ball 8. That is, when the receiving ball 8 enters the limiting port 105, the angle 103 squeezes the receiving ball 8, causing the receiving ball 8 to retract into the limiting port 105, thus preventing the receiving ball 8 from getting stuck.

[0035] See Figure 2 The inner bottom wall of the aluminum strip mounting groove 101 has two heat dissipation holes 102, which are distributed on both sides of the clamping strip 4.

[0036] The heat dissipation vent 102 has the following functions: on the one hand, by squeezing the aluminum strip with your fingers from the heat dissipation vent 102, the end of the aluminum strip is separated from the limiting protrusion 2; on the other hand, the heat dissipation vent 102 itself can dissipate the heat generated at the bottom of the aluminum strip in a timely manner.

[0037] See Figure 2 The heat dissipation vent 102 can be either rectangular or circular. Regardless of the shape, it is necessary to ensure that a finger can be easily inserted into the heat dissipation vent 102.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
