  • Patent number: 6090502
    Abstract: The present invention provides an external battery package unit (10) which houses mechanical and electrical components (32, 34) intended to be electrically connected to a battery (20) and be conveniently mounted to a top surface (22) of the battery (20). The battery unit (10) is made to fit within existing battery size constraints. In an exemplary embodiment, the external battery package unit (10) comprises a first housing (32) which acts as a mechanical compartment and a second housing (34) which acts as an electronics compartment. The first and second housings (32, 34) are secured to one another by a mounting member (30) which adjustably receives a portion of the first and second housings (32, 34) so that a distance between ends of the first and second housings (32, 34) is variable and the relationship between the first and second housings (32, 34) may be adjusted according to external parameters, such as the size of the battery (20) and different tolerances between battery post terminals.

    Abstract: A contact assembly provides a reliable contact between a battery pack and an electronic device. The assembly includes a plurality of contact members and an insulator molded to the contact members. The plurality of contact members preferably include a positive contact member and a negative contact member each having a weldable surface and a selectively plated surface. The weldable surfaces are welded to the positive and negative terminals of the battery pack, respectively. The selectively plated surfaces are preferably plated with gold to ensure a good connection between the device and the battery pack. The insulator serves to fix the contact members relative to each other. In addition, the insulator facilitates minimization of the battery pack size by enabling the contacts to be placed very close to each other.

  • Patent number: 6025088
    Abstract: A lead-acid batteries having terminals designed to readily receive charging leads. The battery terminal and the charging cable lead utilize complementary configurations which interlock and provide an intimate and reliable connection between the terminal and lead. More specifically, an interlocking connection formed by a lead having two parallel legs which slide into slots formed in the wall of the side terminal has proven particularly effective. The interlocking terminal-lead connections eliminate the need of threadingly engaging and disengaging fasteners or adapters during charging that are normally necessary for side terminal batteries.

  • Patent number: 5976729
    Abstract: A cell has an outer can made from either aluminum or an aluminum alloy, and a lead plate for current-utilization. The lead plate for current-utilization is welded to the outer surface of the outer can and further welded to a lead plate for connection which is connected with the protective circuit of the cell. This construction makes it possible to avoid directly connecting the outer can with the lead plate for connection. Consequently, the lead plate for connection can be resistance-welded, so that the protective circuit is prevented form being electrified. As a result, the reliability of the protective circuit is improved, as compared with the case where the lead plate for connection is laser-welded.

  • Patent number: 5965292
    Abstract: A battery terminal case includes an outer case into which a battery is inserted such that an anode and a portion of a cathode can of a battery can be enclosed; a cathode terminal extension member inserted into and nested inside the outer case and contacting the portion of the cathode can; and an anode terminal extension member inserted into the inside of the cathode terminal extension member and contacting the anode of the battery. Accordingly, by using the anode and cathode terminal extension members respectively contacting the anode and the cathode of the battery, damage to the battery itself can be prevented since welding is not necessary during the manufacturing of a battery pack, and contact defects between the battery and the terminal in the conventional terminal case, occurring as the elastic force of the terminal weakens, can be prevented.

  • Patent number: 5861223
    Abstract: A battery terminal post connector in one embodiment includes a spring that urges a lower body towards an upper body when a battery terminal post is disposed therebetween. The urging of the spring causes an electrical connection between the connector and the post. A protective housing protects the connector and the battery terminal post. In another embodiment, a pair of springs are used to create a spring biased connection between lower and upper bodies and a battery terminal post. Thus, in both embodiments, a quick connect/quick disconnect function is achieved for each of the two connectors with respect to each associated battery terminal.
