Description

Technical Field

[0001] This utility model relates to a power battery connection assembly, and more particularly to a power battery connection assembly that uses a U-shaped retractable mounting harness structure. Background Technology

[0002] In recent years, the new energy industry has developed rapidly, and the demand for power batteries has been increasing. Improving production efficiency has become a challenge that enterprises must face. As a key component of power batteries, the installation of the connection assembly is an essential step in the assembly process of power battery modules. Among these steps, the allowance and connection settings of the wiring harness have a significant impact on the smooth installation of the connection assembly. Typically, when installing the connection assembly, the wiring harness installation length needs to be reserved. However, if the excess length is bulging after installation, it will interfere with the module cover, increasing the risk of scratches and potentially leading to serious performance failure. If the wiring harness length is not reserved, the rigid contact during the installation of the connection assembly will increase the risk of component damage. Therefore, there is an urgent need to provide a safe, fast, and convenient power battery connection assembly method. Utility Model Content

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Example 1 This embodiment discloses a power battery connection assembly using a U-shaped retractable mounting harness structure, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes two sets of wire harness isolation plates, each with a frame-type sidewall structure, and an extension platform 11 is formed on the sidewall of any set of wire harness isolation plates. like Figure 3 and Figure 4 As shown, firstly, a through cable tie mounting hole 24 is provided on the extension platform 11, and a cable tie 3 is installed through the cable tie mounting hole 24. The cable tie 3 is mainly used to fix the excess wire harness after installation.

[0019] Secondly, through the joint support of the extension platform 11 and the side wall of the wire harness isolation plate, multiple sets of latch structures are set up, and the multiple sets of latch structures together form a U-shaped wire harness storage and installation site.

[0020] The preferred configuration of the multiple latch structures is three sets: latch structure one 21, latch structure two 22, and latch structure three 23. like Figure 4 As shown, the latch structure 1 21 and the latch structure 3 23 are symmetrically distributed, and the latch structure 2 22 is spaced apart on one side of the latch structure 1 21 and the latch structure 3 23, and is located on the line of symmetry between the latch structure 1 21 and the latch structure 3 23. Thus, through the specific positional distribution of latch structure 1 21, latch structure 22, and latch structure 3 23, a U-shaped wire harness storage and installation point is formed.

[0021] Furthermore, electrical connectors are installed on both sets of wire harness isolation plates, and the wire harnesses are connected by ultrasonic welding; the wire harnesses are connected to connector 5.

[0022] Among them, for wire harness isolation plates with wire harness storage and installation points, the wire harnesses welded to the electrical connection pieces are wire harnesses with reserved installation lengths; When the power battery connection assembly of this embodiment is installed, the cable tie 3 is loosened, and the wire harness with the reserved installation length comes out from the latch structure 21, latch structure 22, and latch structure 23 on the isolation plate 1. The wire harness with the reserved installation length is stretched, which increases the distance between the two sets of wire harness isolation plates, and the connection assembly is smoothly installed on the module. After the installation is completed, the wire harness with the reserved installation length is returned to the wire harness storage and installation point of the latch structure 21, latch structure 22, and latch structure 23 on the wire harness isolation plate 1, forming a U shape. The wire harness retracts back to its original position. Then, it is fixed back to the wire harness isolation plate by the cooperation of the cable tie 3 and the cable tie mounting hole 24.

[0023] Example 2 This embodiment discloses a power battery connection assembly using a U-shaped retractable installation wire harness structure. For ease of description, the two sets of wire harness isolation plates are referred to as wire harness isolation plate one 2 and wire harness isolation plate two 7. like Figure 1 and Figure 2 As shown, the wire harness isolation plate 12 is provided with an extension platform 11, and forms a U-shaped wire harness storage and installation point through the latch structure 1 21, latch structure 22, and latch structure 3 23.

[0024] Among them, electrical connector 1 is installed on wire harness isolation plate 2, and electrical connector 8 is installed on wire harness isolation plate 7; Electrical connector 1 8 is soldered to wire harness 1 4, and electrical connector 2 8 is soldered to wire harness 2 6. Wire harness 1 4 and wire harness 2 6 are then connected to connector 5, and fast and reliable docking between wire harnesses is achieved through connector 5.

[0025] Preferably, the electrical connector is mounted on the wire harness isolation plate via a snap-fit ​​12 and a positioning post 13. Correspondingly, the electrical connector has a positioning hole adapted to the positioning post 13. Thus, after ultrasonic welding, the electrical connector is fixed to the wire harness isolation plate by the engagement of the snap-fit ​​12, the positioning post 13, and the positioning hole.

[0026] For the ultrasonic welding connection between the electrical connector and the wire harness, it is also connected through the thermistor (NTC) 9. Thus, wire harness 1 4 and wire harness 2 6 sample from the electrical connector and the position of the battery cell through the ultrasonic welding point and the NTC, and the sampled information is transmitted to the connector 5.

[0027] In summary, for the power battery connection assembly using the U-shaped retractable installation harness structure disclosed in this embodiment, the harness 4 welded to the electrical connection piece 8 is a harness with a reserved installation length. When the power battery connection assembly of this embodiment is installed, the cable tie 3 is loosened, and the harness 4 comes out from the latch structure 21, latch structure 22, and latch structure 23 on the isolation plate 1, stretching the harness with the reserved installation length, thereby increasing the distance between the two sets of harness isolation plates, and the connection assembly is smoothly installed on the module. After installation, the harness 4 is tidied back to the harness storage and installation points of the latch structure 21, latch structure 22, and latch structure 23 on the harness isolation plate 1, forming a U-shape, and the harness 4 retracts back to its original position. Then, through the cooperation of the cable tie 3 and the cable tie installation hole 24, it is re-fixed to the harness isolation plate.

[0028] Furthermore, preferably, in order to prevent the wire harness slack at the wire harness storage and installation point from easily coming off and forming a U-shape, the slots of the first latch structure 21 and the third latch structure 23 are opened towards the inside of the wire harness storage and installation point, and the slot of the second latch structure 22 is opened towards the outside of the wire harness storage and installation point.

[0029] In summary, the power battery connection assembly using a U-shaped retractable mounting harness structure disclosed in this utility model has the following technical advantages compared with the prior art: The innovative design of the U-shaped retractable installation harness structure solves the problem of damage caused by rigid contact of components when using harnesses of the same size for installation. At the same time, it avoids the serious risk of performance failure caused by the excess length of the harness after installation, which may cause the module cover to arch and interfere with the installation. This makes the installation of the power battery connection components safer, more convenient and faster, and greatly improves production efficiency.

[0030] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
