[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 The structure of a detachable wire harness buckle limiting wire harness applied to a power battery shown in the figure comprises an injection molded isolation plate 2, which also comprises a wire harness buckle 5. A wire groove 4 is formed on the injection molded isolation plate 2, and a wire harness 3 is placed in the wire groove 4. A detachable wire harness buckle 5 is provided above the wire harness 3.

[0020] The wiring harness is limited by the wiring harness buckle, which avoids the scratches on the wire sheath caused by the traditional method and the pain point of difficult insertion of the block structure wiring harness, thereby enhancing the convenience of use.

[0021] The wire harness buckle 5 includes a horizontally arranged limit plate 51, and U-shaped connectors 6 are symmetrically arranged at both ends of the limit plate 51. The injection molded isolation plate 2 is provided with an assembly groove 1 that matches the connector, and the connector 6 is matched and inserted into the assembly groove 1 and is detachably connected thereto.

[0022] The limiting plate is pressed on the surface of the wire harness to limit the wire harness. The connector cooperates with the assembly groove to facilitate disassembly, avoid the problems existing in the prior art, and is more convenient to use.

[0023] In one embodiment, there are multiple harness buckles 5, and the multiple harness buckles 5 are arranged at intervals along the length direction of the injection molded isolation plate. The number of harness buckles is set according to the use requirements, which enhances the use flexibility.

[0024] In one embodiment, a connecting plate 8 is formed on one side of the connecting member 6 away from the limiting plate, the top of the connecting plate 8 is bent in the horizontal direction to form a baffle 7, and a plurality of protrusions 9 are formed at intervals below the baffle 7. When in use, the connecting member is inserted into the assembly groove. Since the connecting plate can move toward the limiting plate when a force is applied to the baffle, the connecting member can be placed in the assembly groove by pressing the baffle toward the limiting plate. After entering the assembly groove, the connecting member will return to its original state due to the cessation of the force applied to the baffle, so that the protrusions are pressed against the assembly groove, thereby achieving a tight connection with the assembly groove, and further limiting the wiring harness.

[0025] In one embodiment, the protrusions 9 are arranged along the horizontal direction of the connecting plate. In order to prevent the connector from falling from the assembly slot, the protrusions are arranged to squeeze the inner wall of the assembly slot to ensure that the connector will not slide from the assembly slot, thereby ensuring stability in use.

[0026] In one embodiment, in order to achieve detachable installation of the connector, the width of the connector 6 gradually increases from the bottom to the top, and in order to facilitate the application of external force to the baffle, the height of the connector 6 is greater than the height of the assembly groove 1.

[0027] In one embodiment, the width of the connecting plate 8 is greater than the width of the connecting member 6. By setting a suitable width for the connecting plate, it is beneficial to effectively limit the wiring harness.

[0028] In one embodiment, the assembly slot 1 opens upward and is hollow, and the width of the assembly slot 1 is smaller than the width of the top of the connector 6. In order to facilitate the buckle fixing of the wiring harness, the assembly slot is matched with the connector to achieve quick disassembly and assembly, thereby enhancing practicality.

[0029] The utility model proposes a CCS assembly solution for wiring harnesses that facilitates the placement of wiring harnesses and limits the wiring harnesses from jumping out of the wiring trough. The solution is suitable for the design of a situation where the battery modules are arranged in multiple rows, the BMU (battery management unit) is located on one side of the PACK (assembly) and is concentrated together, and the space for wiring is limited, and the wiring trough of the previous CCS needs to be used to lay the next CCS wiring harness. Figure 2 shown.

[0030] ①-1: The previous CCS injection molded isolation plate: carries and fixes the functional parts in each CCS component;

[0031] ①-2: The last CCS injection molded isolation plate: carries and fixes the functional parts in each CCS component;

[0032] ②NTC filling component: The resistance of the temperature sensor is inversely proportional to the temperature, which has the effect of collecting the module temperature;

[0033] ③ Connect aluminum bars: connect cells and modules in series to carry current;

[0034] ④ Output pole aluminum bar_positive pole: the battery cells are connected in series, the module carries the current, the module positive pole lead-out terminal is locked and fixed on the module end plate;

[0035] ⑤ Output pole aluminum bar_negative pole: the battery cells are connected in series, the module carries the current, the module negative pole lead-out terminal is locked and fixed on the module end plate;

[0036] ⑥The last CCS harness assembly: connects all functional parts in series and plays the role of current carrying;

[0037] ⑦Wire harness buckle: removable, used to limit the wire harness.

[0038] Depend on Figure 2 It can be seen that the adoption of the solution of the utility model makes the PACK client operation convenient and solves the pain point that the wiring harness is difficult to place into the isolation plate; by replacing the cable tie to fix the wiring harness, the CCS structure of the wiring harness is simplified; the wire insertion and point winding are convenient, and the installation of the wiring harness buckle is simple and reliable, saving multiple steps and improving product output; a smooth transition process is adopted inside the wiring harness buckle, which effectively solves the problem of the wiring harness being scratched compared to the cable tie; the wiring harness buckle improves the space utilization rate of the CCS, avoids the clutter of the cable tie and the potential risk of interference and displacement, and solves the difficulties of insufficient wire installation and wiring space from all aspects.

[0039] The purpose of the utility model is to provide a structure of a detachable wiring harness buckle limiting wiring harness applied to a power battery, which effectively improves the fit of various accessories of the CCS component by adding a detachable wiring harness buckle on the isolation plate instead of the traditional wiring harness fixing solution of cable ties, and makes its structure simpler and more reliable, thereby creating more structural layout space for new energy power battery modules; by adding a detachable wiring harness buckle on the isolation plate instead of the traditional wiring harness fixing solution of cable ties and blocks, the space utilization rate of the CCS component is improved, and effective support is provided for the energy ratio of the new energy power battery module; at the same time, the elimination of cable ties creates effective conditions for the automated production of CCS components.

[0040] The solution of the utility model can be applied to various CCS harness groups that need to share a slot, providing more possibilities for designs with compact PACK space, multiple rows of modules, and insufficient wiring space, so as to meet the design function requirements of customers.
