Abstract: This disclosure depicts a low-cost assembly for mounting a battery, fuse, or other terminal-bearing electrical device on a printed circuit board supporting an electrically conductive pattern. The assembly comprises a one-piece molded receptacle sized and internally configured to receive one or more of such electrical devices, said receptacle having sidewalls and opposed end walls, one sidewall having a pair of slots, one adjacent each end wall. A pair of generally Z-shaped, resilient, electrically conductive, multi-function sheet material members simultaneously provide total mechanical retention of the receptacle on the printed circuit board and make electrical interconnection between an electrical device loaded in the receptacle and the printed circuit board conductive pattern. The assembly provides for total mechanical and electrical coupling with the printed circuit board of a terminal-bearing electrical device loaded into the receptacle.

Abstract: A radio cabinet includes a compartment for three AAA size batteries. The compartment includes a housing having integral means for holding contacts which are intended to engage the batteries only when the batteries are placed in the housing in a predetermined way. The contacts are connected to provide a series-aiding arrangement of the batteries. If any one or more of the batteries is improperly inserted into the housing, electrical continuity is prevented by said integral means.

Abstract: In an electrical storage battery composed of a plurality of electrochemical cells, a keyed linkage system provides for the series connection of the cells in a prescribed order. The system includes the cell terminals, which may be in a stud or tab form, a tooth projecting outwardly in each cell between the terminals, and connecting links which are secured to the terminals of adjacent cells. The size, shape, and location of the tooth permits only a given end of the connecting link to be coupled to one of the terminals, for example, the positive terminal, to accomplish the keying function.

Abstract: A rechargeable plug-in battery compatible with printed circuits and the like. At least one rechargeable storage cell is mounted inside a battery case having at least two terminal pins which extend through the battery case for insertion to a mating socket. Inside the casing, the pins are welded directly to the battery terminals, and recesses formed in the base and cover portions of the battery case at the interior receive the storage cell, or cells, so as to restrain them against movement.

Abstract: A charging system for rechargeable batteries of the 9 volt type includes a charger adapted to accept a plurality of cells of different sizes and electrical characteristics and an adapter module for mechanically and electrically interconnecting the charger to a 9 volt size battery.

Abstract: A battery terminal harness for connection with a predetermined polarity to the dissimilar terminals of a battery is provided with insulating cover means for preventing inadvertent short-term reverse polarity contact between the battery terminals and the connectors of the harness. Fastening means are provided for securing the cover means to a support member, the fastening means including aligned openings in a tab to the cover member and the support member and securing means passing through the aligned openings.

Abstract: A separate charging terminal on a rechargeable battery permits the battery to be recharged in an appliance fitted with a cooperating contact. In this manner only a rechargeable battery may be electrically coupled to the charging circuit of the appliance.

Abstract: A battery assembly including structure for mounting the battery assembly to an exterior surface of a photographic camera such that the terminals of the battery assembly make electrical engagement with a pair of contacts located within the camera thereby providing electrically operated components of the camera with a new source of energy.

Abstract: A battery-connection system for a battery having a pair of battery terminals of opposite polarity and positionable in either of two reversed positionings relative to distribution means. The distribution means includes a pair of spaced electrical terminals of particular and opposite polarity electrically connected with a unit to be powered. A carrier interpositioned between the battery and distribution means including a first pair of electrical contacts in singularly-polarized electrical contacting engagement with the respective battery terminals and a second pair of spaced electrical contacts electrically connected with respective ones of the first pair of contacts for singularly-polarized electrical contacting engagement with the respective pair of distribution means terminals. Each contact of the carrier second pair is of opposite polarity to the other, and comprises a set of plural alternate contacts of the same polarity.

Abstract: A wet cell storage type battery which may be quickly restored to a fully charged condition by the removal and replacement of its electrical generating elements or slowly recharged in the normal manner.

Abstract: A battery cover arrangement for a battery having symmetrically disposed posts of opposite polarity including abutments on at least some of the posts and opposing projections on the underside of the cover which prevent the posts from fully extending through apertures in the cover when the cover is mis-oriented with respect to the polarity of the posts and polarity indicia on the cover.

Abstract: A battery pack for batteries of the type having male and female snap connectors mounted at the opposite ends thereof includes at least two printed circuit boards having male and female snap connectors mounted thereon to receive the snap connectors of the batteries. The snap connectors mounted on the circuit boards are positioned to mechanically engage and electrically contact the snap connectors on the batteries while accommodating limited relative movement of the batteries with respect to the circuit boards, whereby the batteries are floatingly supported. The snap connectors on the circuit boards are electrically interconnected and are electrically connected to terminals for the battery pack by printed circuit layers formed on the circuit boards.

Abstract: Battery operated device has battery wells into which batteries are inserted. Spring-loaded rings in the wells are configured so that electrical contact is not made when the batteries are inserted in the wrong polarity orientation but permit contact when the batteries are correctly inserted.
