Definitions

  • This invention is related generally to composite batteries having independent battery units connected in series to provide a desired size or voltage and, more particularly, to intercell connectors and inter-battery connectors for such composite batteries.
  • the invention i also related to methods and apparatus for making such intercell and inter-battery connectors.
  • An example of the sort of composite battery to which this invention is applicable is an electric battery of th type commonly used m. industry to power lift trucks, golf carts, and electric cars.
  • the invention is applicable to any battery which is constructed of an array of individual units, typically multi-cell units, joined together to form a large battery.
  • Such composite battery is actually an array of discrete independent battery units
  • Each battery unit of such composite batteries include a set of positive plates and a set of negative plates. Th positive and negative plates are separated from each other by battery-plate separators. The positive plates are all affixed to one terminal and the negative plates are affixe to another. The terminals are usually post-like in shape.
  • a cell jar typically made of rubber or plastic and sealed with a cover.
  • the positive and negative terminals protrude through gasketed holes in the cover to provide means for external connections.
  • such battery units ar usually arranged in a tray with the positive terminal of one battery unit next to the negative terminal of the adjacent battery unit.
  • the positive and negative terminal are connected in series by intercell connectors, the array of battery units and intercell connectors forming the composite battery.
  • intercell connectors for composite batteries are usually molded from lead in the form of rigi bars. Such bars can provide excellent conductivity due to their substantial conductive cross-sections. Indeed, it i essential that intercell connectors of composite batteries used for lift trucks, golf carts, and the like have substantial conductive cross-sections; slender wires, thin
  • Center-to-center dimension is used herein to refe to the spacing between the positive and negative terminal of adjacent battery units or, as hereafter seen, to the length of an intercell connector, used to connect such terminals, as measured between the centers of its termina connectors.
  • Shifting and relative movement of the individual unit jar is inherent in the operation of such composite batteries, due to vibration, twisting forces caused by the difficult of supporting such large and heavy battery arrays, therma expansion and contraction, chemical growth on positive plates, and other causes.
  • Individual battery units may move up and down (vertical movement) , side to side (later movement) , and back and forth (longitudinal movement) wit respect to each other, particularly during movement of th vehicle which they power or on which they are supported.
  • intercell connectors of the type described are not readily insulated. The portions lead-burnt onto battery terminals, of course, mus be exposed for such procedures. In any event, insulating such intercell connectors is problematic. Furthermore, intercell connectors of the rigid type are very heavy.
  • Another somewhat similar intercell connector of the prior art includes a solid copper strap with lead lugs which are cast on each end of the copper strap and welded onto the adjacent battery terminals in the same manner as rigid lead connectors.
  • Such intercell connectors offer very little vertical and virtually no lateral or longitudinal flexibility to accommodate relative movement of the battery units.
  • Many of the problems of the previously described intercell connectors apply equally t these connectors. Removal of an individual battery unit connected by such connectors is carried out in the same manner as described above, with all the attendant disadvantages.
  • intercell connector Another type of intercell connector, including one sold by a German company under the trademark “VARTA” and another by an American company under the trademark “DEKKA, is a "bolt-on" intercell connector which- includes a substantially rigid insulated copper cable of round cross section with conventional copper lugs affixed at each end, typically by crimping.
  • the copper conductor is either of rope-lay or concentric-lay construction.
  • intercell connectors which overcomes such problems, combining some or all of th following characteristics: substantial cross-sectional size to allow sufficient current flow; accuracy and ease i connection to and disconnection from battery terminals; an flexibility in a variety of directions to accommodate the relative movements of adjacent battery units in composite batteries and eliminate the attendant stresses and strains on various parts of the composite battery.
  • intercell connectors which, while flexible in various directions, has terminal connectors at its opposite ends with center-to-center spacing equal to the center-to-cente dimensions of the terminals (of adjacent battery units) to be connected.
  • center-to-center dimension of the intercell connector precisely match the dimension between terminals, the extent of battery-unit movement which may be accommodated by the intercell connector, to protect the battery units, can be maximized.
  • attachment of terminal connectors to a cable may be required.
  • attachment of a . terminal connector to a cable has frequently been accomplished by die-casting lead terminals onto cable ends. The cable is held with pincher bars or the like, with the cable end protruding into a mold cavity.
  • Such support would be to expose all other surfaces of the intercell connector such that they are ready for application of insulating material. In such position, drooping of the connector due to its being too long can cause.an uneven, perhaps even unacceptably uneven, application of insulating material, at least if a molding technique is used for application of an insulating material. It is important that the intercell connector no droop between its supporting ends. Consistent length will avoid this problem.
  • Another object of this invention is to provide an improved intercell connector for composite batteries.
  • Another object of this invention is to provide an intercell connector having, at the same time, sufficient cross-sectional size to carry substantial current and sufficient flexibility to accommodate relative movements o the battery units forming the composite battery.
  • Another object of this invention is to provide a composite battery and an intercell connector which facilitate connection and disconnection of the intercell connector from the battery unit terminals.
  • Another object of this invention is to provide an intercell connector of very short length yet having sufficient flexibility in all directions to accommodate relative movements of the battery units of a composite battery.
  • Still another object of this invention is to provide an improved intercell connector which can safely accommodate the relative movements, of an adjacent pair of battery units connected by the intercell connector, in any direction.
  • This invention is an improved composite battery and intercell connector for such composite battery which overcome certain problems and shortcomings of the prior art, including those mentioned above.

  • the intercell connectors, of this invention are compressible, extendable, and bendable in every direction even while firmly connected to terminals at both ends. Indeed, the intercell connector of this invention allows significantly improved vertical, horizontal, lateral, and longitudinal flexibility, including stretching, compressing and twisting, regardless of how short the connectors may be.
  • the intercell connector accommodates relative movement of the battery units forming the composite battery such that the structur and critical junctures of the battery units remain intact. And, while providing these advantages, the intercell connector may readily be connected and disconnected from battery terminals.
  • Another important aspect of this invention is the encapsulation of the intercell connector with an integral, homogenous jacket to electrically insulate it and protect it from corrosion.
  • Such coating extends continuously over both the braided cable and the terminal connectors, leaving only the electrical contact surfaces of the terminal connectors uncovered.
  • the coating while integral over most of the intercell connector, is flexible enough to not interfere significantly with the flexibility provided by the braided cable.

  • Another aspect of this invention is manufacture of the intercell connectors described above.
  • the method and apparatus of this invention represent substantial improvement in die-casting terminal connector onto cables.
  • the method includes placing a substantially straight braided cable of given length onto a sectioned mold with opposite ends of the cable extending into space terminal-connector cavities, and then simultaneously casting terminal connectors onto each end of the cable.
  • This method produces intercell connectors having consiste center-to-center dimensions (that is, the dimension from the center of one terminal connector to the other) .
  • T casting step preferably includes injecting molten metal such as lead simultaneously into the two cavities under equal pressure. Even if there were slight movement of th cable, there will be virtually no deviation in the length of the intercell connectors from the intended length; slight movement of the cable end in an outward direction with respect to the cavity in which it is held would resu in a corresponding inward movement at the other end. In any event, such simultaneous equal-pressure die-casting a opposite ends of a straight length of cable removes the tendency for movement.
