Description

Technical Field

[0002] When the new energy battery pack is working, the voltage signal and temperature signal of its battery cell are transmitted to the BMS for monitoring through the signal acquisition line. Therefore, the sampling harness directly affects the acquisition of battery signals and the service life of the battery, and has very high requirements for the entire electrical system.

[0003] However, the existing signal acquisition lines for new energy battery packs have the following deficiencies when in use: some of the existing signal acquisition lines are equipped with fuses, while others are not. The fuse has the function of automatically blowing out the protection circuit in the event of a short circuit. The existing signal acquisition lines have many production processes, which are complex, not easy to automate, and have high costs. For example, the FFC line is composed of a FFC line and a branch welded together. The welding of the FFC circuit and the branch can only be done by soldering, and the control of the amount of tin is very demanding; the welding position of the FFC circuit and the branch requires additional insulation protection, which will increase the cost; the welding process of the branch and the FFC is relatively complicated, the equipment investment cost is high, and the efficiency is low: cleaning, applying solder paste, inspection, welding, cleaning and inspection, applying glue, and curing. The acquisition line processing process of the prior art is complex, the product flatness is low, and the stability is affected. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

[0022] The signal acquisition line of the new energy power battery pack of the utility model is mainly used to detect the voltage and temperature changes of the battery pack.

[0023] like Figure 4 A collection line with a line sideband positioning structure includes: an upper insulating film 1, a flat conductor 2 and a lower insulating film 3; the upper insulating film, the flat conductor and the lower insulating film are attached and fixed from top to bottom;

[0024] The flat conductor shown is formed by a plurality of flat wires, each of which has at least one narrowed portion narrower than the original width of the wire, and the narrowed portion is a fuse 4; at a distance from the fuse, an upper insulating film is provided with an opening 101 to expose the plurality of flat wires;

[0025] Positioning structures 5 are provided at the edges of the upper insulating film and the lower insulating film, and the number of the positioning structures is equal to the number of the wires; the positions of the positioning structures are close to the corresponding fuses;

[0026] The wire is cut at the opening of the upper insulating film to form a branch bending portion 6 between the fuse and the cut portion. The branch bending portion is bent and fixed in a positioning structure corresponding to the fuse.

[0027] Wherein, the positioning structure is a positioning hole, the cross-sectional shape of the branch bending portion matches the shape of the positioning hole, and the branch bending portion passes through the positioning hole for fixation. Of course, the positioning hole can have a variety of shapes, as long as it matches the shape of the branch bending portion.

[0028] Wherein, the positioning hole is provided with an elastic opening (such as Figure 3 shown).

[0029] Wherein, a positioning structure is provided at the upper part of the edge of the upper insulating film and the lower insulating film, or a positioning structure is provided at the lower part of the edge of the upper insulating film and the lower insulating film. This ensures that the bending direction of the branch bending portion can be unified, which is more conducive to the overall flatness of the product. Furthermore, the bending angle of each branch bending portion is the same, forming a mutually parallel arrangement of the branch bending portions. This arrangement is more neat, conducive to unified processing, and improves processing efficiency.

[0030] The production process of the utility model collection line is as follows:

[0031] Step 1. Figure 1 and Figure 2 shown.

[0032] Use a laminating machine;

[0033] Using an insulating film with hot melt adhesive, holes are opened on the insulating film; wherein the upper insulating film 1 has an opening 101, and the lower insulating film 3 is placed under the flat conductor 2;

[0034] Use a flat conductor 2, which is partially narrowed as a fuse 4;

[0035] The upper insulating film, flat conductor and lower insulating film are bonded together by a bonding machine.

[0036] Among them, the blank area at the edge is appropriately widened to ensure that there is enough space at the edge to add the positioning structure.

[0037] At the same time, flat conductors can also be arranged in the blank areas of the edges, which can enhance the stiffness of the product and prevent it from deforming.

[0038] Step 2. Figure 3 shown.

[0039] The branch part is cut, split and positioned.

[0040] By increasing the width of the edge of the collection line, there is enough space to add the positioning structure 5. The positioning structure can be a positioning hole, and the positioning hole can be of various shapes.

[0041] Step 3. Figure 4 shown.

[0042] Branch bending

[0043] The branch bend 6 is fixed by the positioning structure 5, so that the position of the branch and the flatness of the product are guaranteed, and the processing of the branch and the aluminum row or nickel sheet is convenient. In this step, the finished product image of the collection line of the utility model is basically formed.

[0044] Post-processing, gold finger ( Figure 4 The flat conductor 2) exposed on the left side can be punched into a terminal plug shell to form a plug-in connector.

[0045] The collection line of the utility model can integrate a fuse function, which can play a fuse protection function when a short circuit occurs; the product is flat as a whole, and the line edge has a positioning structure, which can fix all branches and improve the stability of the product; the length is not limited and can be determined according to the actual length used, increasing the flexibility of the product; it is produced by film pasting, the process is environmentally friendly, the process is simple, and the cost is low.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
