Abstract
Terminating an electrical conductor composed of a plurality of conductive strands is accomplished by fusing together the strands at one end of the conductor and immersing the fused end of the conductor in a tinning bath vibrated at ultrasonic speeds, followed by the securing of a terminal to the tinned end of the conductor end preferably under a force sufficient to cause the tinning material to flow and create a metallurgical bond between the conductor and the terminal.

HARTZ ATTORNEYS TERMHNATING OF ELECTRICAL CONDUCTORS The invention herein disclosed relates to the terminating of electrical conductors and more particularly to the terminating of a conductor composed of a plurality of strands of aluminum wire especially adapted for use in the manufacture of vehicle battery cables.
In the manufacture of a battery cable or the like it is desirable to make use of individual strands of aluminum so that the cable will have the desired strength and flexibility. When the aluminum wire is exposed to air, however, a highly resistant oxide forms on the surface of the wire. Removal of the oxide is necessary if a satisfactory electrical connection between the cable and a terminal is to be made. The necessity of removing the oxide film has been recognized heretofore and it has been the practice to apply a chemcial flux to the aluminum wires to dissolve the oxide film. Such fluxes, how ever, wick or migrate along the individual strands of the conductor and react in the presence of moisture en-- countered in the use of the cable to produce corrosive oxides which attack the aluminum and result in failure of the conductor.
An object of this invention is to provide a process especially adapted to obtain an excellent electrical and mechanical connection between an aluminum conductor and a terminal.
Another object of the invention is to provode a process of terminating stranded aluminum conductors which permits the use of conventional terminating equipment and cable processing methods.
has a socket 7 secured at one end of the conductor and a lead-tin alloy battery post clamp 8 having a socket 9 mounted at the opposite end of the cable. The battery cable construction thus far described is conventional.
An aluminum wire or cable exposed to air will oxidize rapidly and form a highly resistant oxide film on its surface. It is known that vibrating a rigid wire or strip of aluminum at ultrasonic speeds will abrade and remove a film of aluminum oxide from the wire or strip. It is also known that ultrasonic vibration of a rigid aluminum wire immersed in a bath of molten solder or zinc-tin alloy not only will abrade aluminum oxide from the wire, but also will enable the latter to be coated with the molten solder or alloy with an extremely good metallurgical bond therebetween. These processes heretofore have not been applicable to conductors formed of a plurality of strands of wire as fine as required in battery cables, however, because the fine strandssimply resonate or vibrate with the result that the oxide film is not abraded. Consequently, a high resistance aluminum oxide film remains on the strands of A further object of the invention is to provide a stranded aluminum cable having at least one terminal thereon and possessing an excellent electrical and metallurgical interface between the conductor and the terminal.
Other objects and advantages of the invention will be pointed out specifically or will become apparent from the following description when it is considered in conjunction with the appended claims and the accompanying drawing, in which:
FIG. l is a flow diagram illustrating the steps of the preferred process;
FIG. 2 is a fragmentary elevational view illustrating one end of a stranded cable preparatory to its being tinned and terminated; and
H6. 3 is an elevational view, partly in section, illustrating a typical battery cable constructed in accordance with the invention.
A battery cable produced according to the invention is designated generally by the reference character 1 and comprises a plurality of individual strands 2 of preferably aluminum wire twisted slightly to form an elongate conductor 3 of suitable length and diameter. A typical cable is composed of 127 strands of 27 gauge wire. The conductor conventionally has an outer layer of rubber or other insulation 4 which is stripped from the ends of the conductor by conventional stripping.
machinery (not shown) so as to expose the ends of the conductor.
The exposed ends of the aluminum cable conventionally are provided with a coating 5 of solder or a zinc-tin alloy for the purpose of minimizing the electromotive potential between the aluminum cable and terminals formed of different metal and adapted to be mounted at opposite ends of the conductor. in the disclosed embodiment, a conventional copper-bearing terminal 6 a stranded conductor, and heretofore has necessitated use of the aforementioned chemical flux to remove the film.
A battery cable constructed according to the invention enables the advantageous effects of ultrasonic vibration of the conductor in a bath of molten solder or zinc-tin alloy to be achieved without the necessity of using a corrosive flux. This result is obtained by fusing or welding the ends of the individual strands 2 together so as to produce at each end of the conductor 3 a solid tip 10. The fusing of the strands at the ends of the conductor may be accomplished by a conventional carbon arc device which generates sufficient heat to puddle the individual strands. As soon as the strands are puddled, the conductor is removed from the carbon arc device whereupon the puddled strands solidify to form the tip 10 at which all of the strands are joined.
The ends of the exposed conductor may be tinned by immersion in an ultrasonically vibrated bath of molten solder or zinc-tin alloy having a temperature lower than the melting point of the aluminum strands 2. The vibration is achieved by a conventional vibrating device such as that manufactured by Branson Ultrasonic instrument Company, of Stamford, Connecticut. The conductor is immersed in the molten metal bath to a depth just short of the insulation and vibrated at an ultrasonic frequency in excess of 20 kilohertz. The thermal and chemical action thereby produced efficiently abrades the oxide film from the conductor and permits the tinning alloy to be bonded metallurgically to the aluminum strands. The fused end of the conductor provides adequate mechanical rigidity for the individual strands of the conductor so as to prevent their oscillating individually in response to the applied ultrasonic frequency, thereby enabling the individual strands to be scrubbed clean of the oxide film and bonded metallurgically to the tinning alloy.
Following tinning of the ends of the conductor the terminals 6 and 8 may be applied thereto. Application of the terminals may be by conventional means such as die casting or by sweating or shrinking a pre-tinned brass type terminal onto the conductor under sufficient force as to cause the coating 5 to flow or become somewhat plastic and thereby form a metallurgical bond between theterminal and the conductor.
Another advantage of fusing the ends of the strands 2 is that, since all of the strands are joined at their ends, all of the strands are capable of carrying current regardless of whether the aluminum oxide is removed from the interior strands of the cable.
This disclosure is illustrative of presently preferred.
