Description of the drawings:

fig. 1 and fig. 2 are the structure diagrams of the present invention.

Fig. 3 is an assembled three-dimensional view of the present invention.

Fig. 4 is an assembly plane sectional view of the present invention.

Fig. 5 is an application structure diagram of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

As fig. 1 to 5, the utility model relates to a soft-packaged electrical core fixed bolster structure, including support body 1, a plurality of support body 1 superposes each other, fixes a soft-packaged electrical core 3 between adjacent support body 1, is equipped with two electric core utmost point ears 31 on soft-packaged electrical core 3.

The bracket body 1 of the utility model is a rectangular frame structure with four sides, and the upper end surface of the front side of the bracket body 1 is provided with a convex part 11; the lower end face of the front side edge is provided with a groove part 12, the middle position of the groove part 12 is provided with a limiting platform 13, and two sides of the limiting platform 13 in the groove part 12 are symmetrically provided with limiting grooves 14.

Four corners of the bracket body 1 are respectively provided with a threaded hole 111 and a tie-hole 112.

The utility model discloses when the assembly, a plurality of support body 1 superposes the back each other, and boss 11 on the adjacent two support bodies 1 pegs graft with concave part 12 each other, and corresponds the preceding terminal surface of the spacing platform 13 of position department and contact with the rear end face of boss 11. Spacing platform 13 can avoid misplacing between adjacent support body 1 effectively, and spacing platform 13 only sets up a segment, during the assembly, is favorable to alleviateing whole weight between.
