An adapter designed to enable a battery, whose shape and dimensions are non-standard, to be housed in an electric appliance such as a model, toy, or portable electric appliance, which has a battery compartment designed to house a standard battery such as type U1, U2 or U3.
A battery holder retains and electrically connects a battery to electrical contacts contained within a housing of an electrical device. The battery holder includes a battery drawer which receives the battery and positions the battery within the housing of the electrical device. The battery drawer includes a rear end wall defining apertures for receiving the terminals of the battery. Pivotable connecting means allow the battery drawer to move within an opening defined in the housing between an open position for receiving the battery and a closed position wherein the drawer and battery are received within the housing. A cam surface within the housing contacts the battery as the drawer is closed and biases the battery against the rear end wall of the drawer to effect engagement of the terminals with the electrical contacts in the housing through the apertures in the rear end wall of the drawer. The apertures are adapted to prevent the battery terminals from being connected to the incorrect electrical contact (i.e. contact of opposite polarity) within the housing. No component of the battery holder may be completely detached from the housing of the electrical device.
An adapter consisting of a tube with one mode using a metallic base that provides a support for the electrical conducting spring whose function is to complete an electrical circuit between base of tube and base of "C" cell battery that will be in contact with spring when adapter is in use.
A battery contact and holding apparatus (10, 200) includes a door (12, 212) and a battery compartment 14, 214) associated with the door. The door selectively provides access to the interior (16, 216) of the battery compartment. The apparatus also includes a plurality of contacts (86,88,286,288) for electrically coupling to a battery (64, 264) in the battery compartment and a post locator (56, 256) associated with the battery compartment for aligning one or more posts (62,66, 262,266) of a battery with one or more of the plurality of contacts and for disallowing the door to close off the interior of the battery compartment if a battery is not properly placed.
A cell box includes a casing and a cell-positioning holder. The casing has a cavity capable of receiving either a first cell or a second cell which are different in shape from each other. The holder is arranged in the cavity. The holder has a through hole capable of receiving a part of said second cell and holds said part in a direction substantially vertical to a longitudinal axis of said through hole. Further, the holder has a surface capable of holding said first cell with an inner surface of the casing in a direction of said longitudinal axis. The cell box is a compact and handy one which is capable of receiving either two types of cells, and it is particularly useful for an optical apparatus which consumes a relatively large electric power and is used outdoors.
