[0035] To make the technical content, the purposes and effects achieved by the utility model more clear, the following will be explained in combination with the embodiments and the accompanying drawings.

[0036] Please refer to Figure 1 The utility model provides a technical scheme: a kind of insulating clamp, including clamp body and insulating sheet, one side of the insulating sheet is connected with several insulating sheet fixing rings;

[0037] The insulating sheet is fixed by the insulating sheet fixing ring around the concave surface of the clamp body.

[0038] From the above description, the beneficial effects of the utility model are that: using insulating sheet to replace heat shrink sleeve, without changing the insulating effect, greatly reduces the material cost;At the same time, the insulating sheet adhesion connection is used to replace the heat shrink sleeve heating tightening, and the process is simpler and more efficient, and the insulation area positioning is more accurate;The blanking and cutting of insulating sheet are more convenient than heat shrink sleeve, and when mass production, mold can also be opened, which greatly reduces the production time. The technical scheme of the utility model only needs to be pasted and fixed after simple tool positioning, and can be installed after module assembly or installed synchronously when clamp body production, compared with the complicated steps of using heat shrink sleeve heating tightening, cutting and Teflon wrapping, the installation process is simplified, accurately positioned, and the cost is reduced.

[0039] Further, the insulating sheet and the insulating sheet fixing ring are made of PC material.

[0040] As can be seen from the above description, the PC insulating sheet has excellent comprehensive performance such as insulation, aging resistance, flame retardation, etc. The selection of the PC insulating sheet as the insulating layer of the hoop body improves the insulation performance and prevents accidental electric leakage.

[0041] Further, the width of the insulating sheet fixing ring is 6-10 mm, and the thickness of the insulating sheet is 0.2-0.3 mm.

[0042] As can be seen from the above description, the width of the insulating sheet fixing ring is set to 6-10 mm, which facilitates the fixation of the insulating sheet on the hoop body; and the insulating sheet is selected to have an appropriate thickness to provide sufficient insulation strength while reducing the overall thickness of the insulating hoop.

[0043] Further, the insulating sheet fixing ring is adhesively fixed to the insulating sheet.

[0044] As can be seen from the above description, the fixation is facilitated while the stability of the fixation between the insulating sheet and the insulating sheet fixing ring is ensured, and they will not easily separate.

[0045] Further, the top end of the insulating sheet fixing ring is provided with an adhesive area.

[0046] The length of the adhesive area is equal to the width of the insulating sheet fixing ring, and the width of the adhesive area is 3-5 mm.

[0047] As can be seen from the above description, a part of the top of the insulating sheet fixing ring is used as the adhesive area of the insulating sheet and the insulating sheet fixing ring, which strengthens the fastening of the adhesion between them and improves the stability of the insulating layer of the insulating hoop.

[0048] Further, the distance between the adhesive area and the hoop body is 0.3-0.5 mm.

[0049] As can be seen from the above description, since there is a tolerance float in the width of the hoop body during the manufacturing process, the adhesive area is spaced a certain distance from the hoop body, which increases the wrapping range of the insulating sheet fixing ring and ensures that the hoop body can always be embedded in the groove of the insulating sheet fixing ring, so that the hoop body will not be unable to be covered due to the small wrapping range of the insulating sheet fixing ring.

[0050] Further, the distance between any two adjacent insulating sheet fixing rings is equal.

[0051] The adjacent distance of the insulating sheet fixing rings is 65-75 mm.

[0052] As can be seen from the above description, the moderate distance and the same spacing of any two adjacent insulation sheet fixing rings can provide stable and reliable fixing effect.

[0053] Further, the width of the hoop body is 24-25mm.

[0054] As can be seen from the above description, the appropriate width of the hoop body is conducive to strengthening the fixing and supporting effect of the battery module and ensuring its stability and safety.

[0055] On the other hand, the utility model provides a kind of energy storage module, including electric core, end plate, top fixing and insulation hoop;

[0056] The insulation hoop is the insulation hoop described above;

[0057] The insulation sheet of the insulation hoop is symmetrically located on the two sides of the energy storage module.

[0058] The end plate is located at the two ends of the energy storage module, and is fixed with the electric core by the insulation hoop and the top fixing.

[0059] As can be seen from the above description, the utility model has the beneficial effects that: using insulation sheet instead of heat shrink sleeve greatly reduces material cost without changing insulation effect; At the same time, the insulation sheet adhesion connection replaces heat shrink sleeve heating tightening, and the process is simpler and more efficient, and the insulation area positioning is more accurate; The blanking and cutting of insulation sheet are more convenient than heat shrink sleeve, and the mold can be opened when mass production, which greatly reduces the production time. The technical scheme of the utility model only needs to be pasted and fixed after simple tool positioning, and can be installed after module assembly or installed simultaneously during hoop body production, Compared with the complicated steps of using heat shrink sleeve heating tightening, cutting and teflon wrapping, the installation process is simplified, accurate positioning is realized, and cost is reduced.

[0060] Further, the end plate is made of aluminum alloy material, and a gap is left between the end plate and the insulation sheet.

[0061] As can be seen from the above description, through tool positioning, the insulation sheet is not worn out by the mutual extrusion of aluminum alloy end plate and hoop body.

[0062] Please refer to Figures 1 to 4 , the embodiment one of the utility model is:

[0063] As Figure 1 shown, an insulation hoop includes a hoop body 1 and an insulation sheet 2, one side of the insulation sheet 2 is connected with a plurality of insulation sheet fixing rings 21.

The insulating sheet 2 is made by bending and punching process, and is fixed on the hoop body 1 by the insulating sheet fixing ring 21 and the 3M back adhesive 22, and the distance between the 3M back adhesive 22 and the hoop body 1 is 0.5 mm, that is, the wrapping area of the fixing ring is larger than the hoop body 1, and the gap formed can absorb the corresponding width tolerance of the hoop body 1, so that the insulating sheet fixing ring 21 can wrap and clamp the hoop body 1. The number of the insulating sheet fixing ring 21 is determined according to the length of the hoop body 1, and the distance between the adjacent insulating sheet fixing rings 21 is 68 mm, which provides reliable fixing effect.
