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

[0021] Embodiment:

[0022] As Figure 1 And Figure 2The utility model provides a kind of harness fixing structure for energy storage battery and power battery, including isolation plate 1, first baffle 8 and second baffle 9 are fixedly arranged on the upper end surface of isolation plate 1 to form harness fixing groove 3, several harnesses 2 are closely arranged inside harness fixing groove 3;The accommodation space of multiple harnesses 2 makes the placement of harness 2 more convenient, greatly reduces the possibility of damage to wire skin due to narrow space in the operation process;Harnessed 2 is arranged in order, avoids disorderly stacking, improves the safety of overall structure.

[0023] First female buckle 4 and second female buckle 6 are symmetrically flexible hinged in the width direction of the upper end surface of first baffle 8;By thinning the thickness of the bottom end of first female buckle 4 and second female buckle 6, the hardness of this part can be reduced, thereby enhancing the toughness of the bottom of first female buckle 4 and second female buckle 6, so that they can be bent, with higher flexibility and adaptability;

[0024] First male buckle 5 and second male buckle 7 are symmetrically fixed in the width direction of second baffle 9 to cooperate with first female buckle 4 and second female buckle 6 respectively.

[0025] Several harnesses 2 are arranged in harness fixing groove 3 in an orderly and full manner, first female buckle 4 is buckled to first male buckle 5, second female buckle 6 is buckled to second male buckle 7, and several harnesses 2 in harness fixing groove 3 are fixed, which does not require the purchase of any new equipment, reduces the investment cost of new equipment under the condition of ensuring the firm fixation of harness 2, effectively reduces the production cost, improves the production capacity, and reduces the difficulty of FPC flexible circuit board mass production.

[0026] First baffle 8 and second baffle 9 are symmetrically arranged on the upper end surface of isolation plate 1 in the length direction, the height of first baffle 8 is equal to the height of second baffle 9, the length of first baffle 8, the length of second baffle 9 and the length of several harnesses 2 are equal, and the harness fixing groove 3 is a U-shaped limiting mechanism, which can make the transverse part of the harness 2 inside the harness fixing groove 3, only the two end surfaces of the harness 2 are exposed outside, which can tightly fix the harness 2 in the harness fixing groove 3;Therefore, since the main part of the harness 2 is fixed in the groove, the contact area with the external environment is reduced, and the two exposed end surfaces can achieve good heat dissipation effect by air flow, keeping the temperature of the harness 2 within a safe range;

[0027] Tightly and firmly fixing the harness 2 inside the harness fixing groove 3 not only makes the layout of the harness 2 more compact, reduces unnecessary space waste, improves the utilization rate of space, optimizes the overall volume of the battery pack, but also effectively improves the energy density of the battery pack, improves the energy storage capacity of the battery pack, and maintains the high energy output of the battery pack.

[0028] The isolation plate 1 is symmetrically provided with an opening, and a same groove is provided at a position corresponding to the second partition plate 9 for fixing the first male buckle 5 and the second male buckle 7; the extension direction of the first male buckle 5 is consistent with the extension direction of the second male buckle 7; the first male buckle 5 and the second male buckle 7 are connected through the groove provided on the second partition plate 9; when the first female buckle 4 cooperates with the first male buckle 5 and the second female buckle 6 cooperates with the second male buckle 7, a certain buffer force can be given to the first male buckle 5 and the second male buckle 7 through the opening, so that the cooperation is smooth, and the stability of the whole structure and the convenience of assembly are ensured.
