Abstract
Abstract A battery holder assembly for holding a cluster of four elongate battery cells in the handle of a battery-powered movie camera or the like. The complete assembly includes a removable cassette for receiving and retaining the four battery cells in a side-by-side assembled relationship. The cassette, in turn, is received within a housing formed by the handle. In the battery holder assembly disclosed, electrical connection will not be completed with a battery cell that is improperly inserted in reversed polarity orientation.

324 words
A battery holding assembly for elongate battery cells of the type having a central protruding positive terminal at one end and a negative terminal surface at the opposite end, said assembly comprising: an elongate cassette for receiving and retaining a predetermined number of said battery cells in a side-by-side assembled relationship, said cassette comprising a first portion and a detachable second portion with one end wall formed as a part of said first portion and an opposite end wall formed as a part of said second portion, said first portion being attachable to said second portion in only two possible 180* rotated orientations; means projecting longitudinally within said cassette for defining a longitudinal compartment for each of said predetermined number of batter cElls, said cassette end walls providing for each battery cell compartment a pair of aligned contact-receiving apertures, a first one of said pair of aligned contact-receiving apertures having a minor diameter and a second one of said pair of contact receiving apertures having a major diameter larger than said minor diameter; spacer means providing a raised surface region on the interior surface of each of said end walls adjacent the first one of each of said pair of aligned apertures and configured to form a socket for receiving the protruding positive battery terminal only, whereby electrical contact may be prevented with the negative terminal of a battery cell should the battery cell be improperly inserted in said cassette in reversed polarity orientation; and a receiver housing for longitudinally receiving said cassette, said receiver housing having a pair of end walls each including a predetermined number of inwardly protruding electrical contact elements positioned to enter said contact-receiving apertures of said cassette for establishing electrical contact with said battery cells when said battery cells are properly oriented in said cassette, said electrical contact elements including a negative electrical contact element having a dimension larger than the minor diameter and smaller than the major diameter.
