[0020] The utility model will be further explained in detail in connection with the drawings and specific embodiment.

[0021] Embodiment:

[0022] As Figs. 1-2 Shown, a kind of S-shaped telescopic installation FPC's power battery connecting assembly, including FPC plate 4, first wire harness isolation plate 1 and second wire harness isolation plate 2, FPC plate 4 is S-shaped;The front end and rear end of FPC plate 4 are both fixedly connected with reinforcing device;

[0023] The front end of the FPC plate 4 is fixedly connected with the first wire harness isolation plate 1 through the reinforcing device, and the rear end of the FPC plate 4 is fixedly connected with the second wire harness isolation plate 2 through the reinforcing device; a plurality of electric connection sheets 3 are hot rivet welded on the first wire harness isolation plate 1 and the second wire harness isolation plate 2, and a plurality of nickel sheets 44 are laser welded on the electric connection sheets 3 and are located above the electric connection sheets 3 for collecting information; after laser welding, the electric connection sheets 3 and the nickel sheets 44 are fixed on the first wire harness isolation plate 1 and the second wire harness isolation plate 2 through hot rivet welding.

[0024] Both sides of the FPC plate 4 are fixedly provided with extension plates, and the lower end surface of each extension plate is welded with an NTC thermistor 45 for collecting information of the battery cell. The extension plate is L-shaped.

[0025] The reinforcing device comprises a PI reinforcing sheet 42 and a connector, and the connector is fixedly arranged in the middle of the PI reinforcing sheet 42 for collecting information of the electric connection sheet 3. A mounting hole 43 is formed in the PI reinforcing sheet 42 for mounting on the wire harness isolation plate; a plurality of nickel sheets 44 are fixedly arranged at the lower end of the PI reinforcing sheet 42.

[0026] The first wire harness isolation plate 1 and the second wire harness isolation plate 2 are both U-shaped. The two side walls of the first wire harness isolation plate 1 and the two side walls of the second wire harness isolation plate 2 are both provided with buckles for being further fixed in the module; an opening is formed in the upper end surface of the first wire harness isolation plate 1 and the upper end surface of the second wire harness isolation plate 2, and the opening corresponds to the plastic hinge of the FPC plate 4, so that the opening is convenient for preventing parts from being scratched when being hinged.

[0027] A back adhesive 46 is arranged at the lower end surface of the FPC plate 4 for bonding the upper cover of the module, so as to enhance the firmness and stability after installation.

[0028] The installation process of the utility model to the module is as follows:

[0029] I. The FPC plate is pulled in the opposite direction, and under the action of the S-shaped FPC plate 4, the distance between the first wire harness isolation plate 1 and the second wire harness isolation plate 2 is increased;

[0030] II. The power battery connecting assembly is placed on the module;

[0031] III. Since the S-shaped FPC plate 4 is stretched under the action of the opposite force, the S-shaped FPC plate 4 is retracted to the original position after the opposite force disappears;

[0032] IV. Under the action of the back adhesive 46 at the rear end surface of the FPC plate 4, the back adhesive 46 is pasted on the upper cover of the module;

[0033] V. The installation is completed.

[0034] By setting the FPC board 4 into an S shape, in the actual installation process, the S shape setting allows the FPC board 4 to have a certain stretching space, effectively solving the mechanical damage problem that may be caused by the rigid contact between the various electronic parts when the same size FPC board 4 is used for installation of the module; and this installation method does not need to reserve additional installation length on the FPC board 4, avoiding the situation that the FPC board 4 is left over after installation and interferes with the cover of the module, greatly reducing the risk of performance failure caused by scratches, and ensuring the stability and reliability of the electronic equipment.

[0035] The above embodiments are not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the technical solution range of the present application also belong to the protection scope of the present application.
