Summary of the invention
In order to preferably realize the location to lithium battery, making electrical connection properties good, this utility model provides a kind of lithium battery shell.
For reaching above-mentioned purpose, a kind of lithium battery shell, including housing and upper cover；Described housing has containing cavity, is provided with and upwardly extending keeps out wall on the rear wall of housing, the two opposite side walls of housing is provided with extend internally keep out limit, the side keeping out limit is lithium battery containing cavity；It is positioned in the bottom of housing and keeps out the opposite side on limit and be provided with electrode accommodating hole, in electrode accommodating hole, be provided with electrode slice, the upturned extension after lithium battery containing cavity direction extends of electrode slice self-electrode accommodating hole, electrode slice is suppressed with pressing plate；The medial wall keep out wall is provided with draw-in groove, the front side wall of housing is provided with bayonet socket；Described upper cover includes upper cover body, is located at the fastening part on rear side of upper cover body, is located at the buckle of upper cover body bottom portion and is located at the pressing part of upper cover body bottom portion；Fastening part holding is in draw-in groove, and buckle and bayonet fittings, pressing part is compressed on pressing plate.
The shell mechanism of said structure, owing to defining lithium battery containing cavity, and lithium battery containing cavity is by housing and to keep out limit and formed, accordingly, it is capable to preferably position lithium battery.It is provided with electrode accommodating hole at the opposite side keeping out limit, electrode accommodating hole is provided with electrode, electrode is suppressed by pressing plate, and after covering upper cover, pressing part is compressed on pressing plate, pressing plate energy electrode pressing reliably, can prevent electrode from departing from housing, simultaneously as use upturned electrode, therefore, lithium battery can be electrically connected with reliably with electrode.Owing to being provided with draw-in groove, bayonet socket, fastening part and buckle, therefore, the connection that upper cover is installed to drain pan is reliable, and convenient disassembly.Keeping out wall owing to being provided with, after upper cover is installed, the trailing flank of upper cover is kept out and is being kept out on wall so that the accurate positioning of upper cover, fixing reliable.
Further, being provided with breach keeping out on wall between draw-in groove, breach extends in housing front side wall, and breach is less than keeping out wall.Owing to breach is less than keeping out wall, therefore, on upper cover lid after, indentation, there forms passage, and so, the heat in containing cavity easily scatters and disappears, and improves the service life of lithium battery.
Further, being provided with groove on the front side wall of housing between bayonet socket, the two opposite side walls of groove is provided with the gusset extended internally.So, wire can be allowed to pass, and be conducive to heat radiation.
Further, the cross section of pressing part is T-shaped.Using this cross section structure, the area that pressing part is applied to pressing plate is big, and therefore, pressing part is reliable to the active force of pressing plate.
Further, the end face of upper cover body is provided with convex tendon, the intensity of upper cover can be improved.

Detailed description of the invention
With detailed description of the invention, this utility model is further elaborated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of lithium battery shell includes housing 1 and upper cover 2.
As shown in Figures 2 to 5, described housing 1 has containing cavity 11, is provided with and upwardly extending keeps out wall 12 on the rear wall of housing 1；The medial wall keeping out wall 12 is provided with draw-in groove 15；Being provided with breach 16 on wall 12 between draw-in groove 15 keeping out, breach 16 extends in housing front side wall, and breach is less than keeping out wall 12, therefore, after upper cover 2 covers, at breach 16, form passage, so, the heat in containing cavity easily scatters and disappears, and improves the service life of lithium battery.The two opposite side walls of housing 1 is provided with extend internally keep out limit 13, the side keeping out limit 13 is lithium battery containing cavity 111；It is positioned in the bottom of housing 1 and keeps out the opposite side on limit 13 and be provided with electrode accommodating hole 14, in electrode accommodating hole 14, be provided with electrode slice 3, the upturned extension after lithium battery containing cavity direction extends of electrode slice 3 self-electrode accommodating hole, electrode slice 3 is suppressed with pressing plate 4.The front side wall of housing 1 is provided with bayonet socket 17.Being provided with groove 18 on the front side wall of housing 1 between bayonet socket 17, the two opposite side walls of groove 18 is provided with the gusset 19 extended internally, and so, wire can be allowed to pass, and is conducive to heat radiation.
