Description

Technical Field

[0001] The utility model relates to a CCS component, in particular to a hot-pressing type environment-friendly polyolefin electrical connection CCS component. Background Art

[0002] With the rise of new energy vehicles, the components used in conjunction with new energy vehicles have also developed. Among them, the CCS (Cruise Control System) component is an important part of the power battery module, mainly playing the roles of power transmission, signal acquisition, and battery management. The traditional hot-pressing type CCS (Cruise Control System) component consists of an aluminum bar assembled on the bottom-layer hot-pressing film. The electrical connection part uses an FPC, and the FPC is connected to the aluminum bar by laser welding. The upper-layer hot-pressing mold and the lower-layer hot-pressing mold are pressed together.

[0003] Among them, the aluminum bar needs to be bent. After bending, the structure is relatively high, which will compress the space inside the box. Bending requires adding an aluminum bar process and increasing aluminum bar processing tooling. The FPC is basically a customized part, with a high cost and a long processing cycle. The chemical wastewater after line etching in the FPC processing process will bring environmental protection problems. At the same time, due to the reason of the FPC conductor thickness, it cannot pass a large current and cannot play the role of replenishing power for the battery cells. After the traditional wire is welded to the aluminum bar, UV glue needs to be applied at the solder joint to protect the solder joint after curing, which increases the material cost and the process cost. Summary of the Utility Model

[0004] In order to solve the deficiencies of the above technologies, the utility model provides a hot-pressing type environment-friendly polyolefin electrical connection CCS component.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a hot-pressing type environment-friendly polyolefin electrical connection CCS component, including an upper-layer PET hot-pressing film, an aluminum bar, and a lower-layer PET hot-pressing film that form a pressed sandwich structure from top to bottom. One end of the aluminum bar is welded to one end of an environment-friendly polyolefin wire, and the other end of the environment-friendly polyolefin wire is inserted into a connector through a crimping terminal. The connector is located outside the pressed sandwich structure formed by the upper-layer PET hot-pressing film, the aluminum bar, and the lower-layer PET hot-pressing film.

[0006] Further, the shapes, sizes, and openings of the upper-layer PET hot-pressing film and the lower-layer PET hot-pressing film are mutually adapted.

[0007] Further, a first wire management groove for accommodating the routing of the environment-friendly polyolefin wire is provided on the upper-layer PET hot-pressing film.

[0008] Further, a second wire management groove for accommodating the routing of the environment-friendly polyolefin wire is provided on the lower-layer PET hot-pressing film.

[0009] Furthermore, the first cable management slot and the second cable management slot correspond to each other and are implemented in pairs.

[0010] Furthermore, there are multiple aluminum bars, which are spaced apart and laid flat on the lower PET hot pressing film.

[0011] Furthermore, each of the aluminum bars is formed with anisotropic notches.

[0012] A hot-pressed environmentally friendly polyolefin electrically connected CCS component eliminates the bending of traditional aluminum bars, saves battery pack space, reduces mold costs, and reduces processes; the overall structural setting solves the problems of FFC's inability to recharge the battery cells individually, high cost, difficulty in passing environmental protection, and long manufacturing cycle; the glue-dispensing protection method of the wire and aluminum bar welding point is eliminated and replaced by an upper layer of hot-pressed film pressing, which simplifies the process, eliminates UV glue, and saves material costs; the setting of the upper and lower layers of hot-pressed films increases the insulation pressure resistance and temperature resistance of the wire.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1-2 As shown together, this embodiment is about a hot-pressed environmentally friendly polyolefin electrical connection CCS component, including an upper PET hot-pressed film 1, an aluminum bar 3, and a lower PET hot-pressed film 6 that form a pressed sandwich structure from top to bottom. The aluminum bar 3 is welded to one end of the environmentally friendly polyolefin wire 4. In actual processing, the environmentally friendly polyolefin wire 4 is ultrasonically welded to the aluminum bar 3 to realize the functions of voltage collection and active balancing mode power replenishment. The other end of the environmentally friendly polyolefin wire 4 is connected to the connector 5 through a crimping terminal. The connector 5 is located outside the pressed sandwich structure formed by the upper PET hot-pressed film 1, the aluminum bar 3, and the lower PET hot-pressed film 6.

[0021] On this basis, the first wire management trough 2 and the second wire management trough 7 correspond to each other and are implemented together. That is, the grooves of the single corresponding first wire management trough 2 and the grooves of the second wire management trough 7 are paired with each other to accommodate the routing of the environmentally friendly polyolefin wires 4. This routing method can avoid pressing on the environmentally friendly polyolefin wires 4.

[0022] There are multiple aluminum bars 3, and the multiple aluminum bars 3 are laid flat on the lower PET hot pressing film 6 at intervals to ensure that the aluminum bars 3 are in one layer. In actual processing, the lower PET hot pressing film 6 is laid on the front end tooling, and then the aluminum bar 3 is placed on the lower PET hot pressing film 6 through the front end tooling positioning position, and then the upper PET hot pressing film 1 is assembled on top of the welded aluminum bar 3, and finally heated and pressurized for pressing.

[0023] Preferably, each aluminum bar 3 is formed with an anisotropic notch 8, and the anisotropic notch 8 is used to absorb deformation caused by extrusion or stretching when subjected to force.

[0024] The present application discloses a hot-pressed environmentally friendly polyolefin electrical connection CCS component, which eliminates the bending of traditional aluminum bars, saves battery pack space, reduces mold costs, and reduces processes; the overall structural setting solves the problems of FFC's inability to recharge the battery cells individually, high cost, difficulty in passing environmental protection, and long manufacturing cycle; the glue point protection method of the wire and the aluminum bar welding point is cancelled, and the upper hot pressing film is used instead, which simplifies the process, eliminates UV glue, and saves material costs; the setting of the upper and lower hot pressing films increases the insulation pressure resistance and temperature resistance of the wire.
