Embodiment

See also Fig. 1～shown in Figure 5, it is the preferred embodiment of the utility model battery structure 1, comprises a housing 2, a rupture pressure disc 3, a cover plate 4, two gum covers 5, an insulation offset plate 6, two terminal blocks 7 and two connector assemblies 8.

This housing 2 is the rectangular body of hollow, comprises that the lower house 22 and that a top has an opening 21 covers at the top board 23 of the top of lower house 22 to seal this opening 21.The central part of this top board 23 forms a upper and lower circular perforations 231 that runs through top board 23, and this circular perforations 231 is sealed with rupture pressure disc 3, and the top of rupture pressure disc 3 covers a cover plate 4, has a plurality of through holes 41 on this cover plate 4.Form a upper and lower rectangle fluting that runs through top board 23 on the top board 23 of circular perforations 231 both sides respectively and be positioned at, with via direct injection molding way, moulding one cross section summary is the gum cover 5 of H shape on arbitrary fluting, and arbitrary gum cover 5 is provided with two and has circular duct 51 at interval.

The plate body that this insulation offset plate 6 is rectangle for summary, it is pasted below the top board 23 of housing 2, and forms two rectangular slots 61 on the insulation offset plate 6; And any terminal block 7 comprises a fin 72 that is positioned at the fixed head 71 on terminal block 7 tops and is extended by fixed head 71 both sides respectively downwards, in addition, forms two circular ports 711 on any fixed head 71.

This arbitrary connector assembly 8 comprises a fixture 81, a spacer 82 and an on-slip part 83.In the present embodiment, this fixture 81 is inverted T-shape, comprises that 811, two of rectangle bottoms are protruded by bottom 811 and have rivet and at interval by the upwardly extending double-screw bolt of the central part of bottom 811, wherein downwards, this rivet is as keeper 812, and this double-screw bolt is as erection part 813.From top to bottom pass two circular ports 711 on two circular ducts 51 of gum cover 5 and terminal block 7 tops when two rivets after,, fixture 81, top board 23, gum cover 5 and terminal block 7 can be closely linked by the pressure effect of rivet driver.During enforcement, this keeper 81 also can be double-screw bolt, and relies on the combination of corresponding nut, and fixture 81, top board 23, gum cover 5 and terminal block 7 are closely linked.

This spacer 82 is an annular gasket, and it is socketed on the erection part 813.And the bottom of spacer 82 is provided with an on-slip face 821, and on-slip face 821 comprises a plurality of in the same plane and following helical teeth 823 of being in array-like arrangement; In addition, a matsurface 822 is formed on the top of spacer 82, and matsurface 822 comprises a plurality of last helical teeth 824 that are positioned at same plane and are in array-like arrangement.These a plurality of space widths of helical teeth 824 of going up are greater than these a plurality of space widths of helical teeth 823 down.

And this on-slip part 83 is a nut, for being threaded on the erection part 813 of fixture 81.During enforcement, this on-slip part 83 also can be a bolt of taking the lead, and the erection part 813 of fixture 81 then is to be a nut, can allow on-slip part 83 and fixture 81 be threaded togather equally.And when on-slip part 83 be threaded with the erection part 813 of fixture 81 after, on-slip part 83 is positioned at the top of spacer 82.The bottom surface of this on-slip part 83 forms a matsurface 831, and matsurface 831 comprises a plurality of conplane helical teeth 832 that are positioned at, and the space width of these a plurality of helical teeth 832 equals the space width of spacer 82 helical teeth 824 on each.
