Abstract
A casing for a battery of cylindrical electric cells lying parallel to one another includes two insulating half casings each formed by one or more modules (2) having n or n+1 recesses in the form of part cylindrical cavities. The modules have two end edges and have respective complementary interfitting portions (24, 25) enabling two modules to be connected end-to-end. Each module further has two base plates (26, 27) orthogonal to the axes of said part cylindrical cavities and having complementary fixing parts (28, 29). A casing having any number of cell-receiving recesses greater than one can be assembled from modules having n and n+1 part cylindrical cavities, where n is equal to 2.
Claims14
A casing for a battery of cylindrical electric cells lying parallel to one another, wherein the casing comprises interconnected first and second insulating half casings with each half casing comprising at least one module having n and one module having n+1 part cylindrical cell-receiving cavities extending parallel to one another between base plates which are orthogonal to the axes of said part cylindrical cavities, the end edges of the cavities being provided with respective first complementary interfitting portions to enable a plurality of modules to be connected end-to-end to increase the number of side-by-side cell-receiving cavities in a half casing, and the base plates being provided with respective second complementary interfitting portions to enable the first and second half casings of any one battery to be assembled with the cavities facing each other.
A molded insulating casing for a battery of cylindrical electrical cells, the casing comprising two half casings, each half casing including at least two modules assembled in the form of an open box having a base wall formed with at least 2n+1 part cylindrical cell-receiving cavities, n being an integer, such that each half casing has the same total number of cell-receiving cavities, and the two half casings together include two modules having n cell-receiving cavities and two modules having n+1 cell receiving cavities, the cavities having axes arranged in parallel coplanar relation, and each module having two spaced apart end edges parallel to the axes of the cavities, said end edges being provided with respective first complementary interfitting portions to enable a plurality of said modules to be connected end-to-end to form said half casings, and each module having two spaced apart side walls perpendicular to the axes of the part cylindrical cavities, said side walls being provided with second complementary interfitting portions for releasably locking together the two half casings with the part cylindrical cavities of said half casings facing each other.
A molded insulating casing for a battery of cylindrical electrical cells, the casing comprising two half casings, each half casing including at least one module assembled in the form of an open box having a base wall containing at least n+1 part cylindrical cell-receiving cavities, n being an integer, such that each half casing has the same total number of cell-receiving cavities, and the two half casings together include at least one module having n cell-receiving cavities and one module having n+1 cell-receiving cavities, the cavities having axes arranged in parallel coplanar relation, and each module having two spaced apart end edges parallel to the axes of the cavities, said end edges being fitted with respective first complementary interfitting portions to enable a plurality of said modules to be connected end-to-end to form said half casings, and each module having two spaced apart side walls perpendicular to the axes of the part cylindrical cavities, said side walls being provided with second complementary interfitting portions for releasably locking together the two half casings with the part cylindrical cavities of said half casings facing each other.
