ELECTRICAL TERMINAL AND METHOD OF FORMING AN ELECTRICAL CONNECTION TI-IEREWITH BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention pertains to electrical connections and, more particularly, to an electrical terminal and a method of forming a permanent electrical connection between an electrical terminal and a lead wire.
2. Discussion of the Prior Art art Electrically operated appliances conventionally utilize electrical terminalsadapted to be electrically connected with lead wires by soldering, brazing, welding or otherwise mechanically bonding the electrically conductive elements; however, such electrical connections have the disadvantages of requiring special equipment and experienced technicians as well as being difficult to implement for wires of small diameter.
Prior art attempts to obviate the need for soldering and the like in forming electrical connections have utilized screw and wrapped binding posts, as disclosed in US. Pat. No. 2,759,166 to Mallina; however, such prior art attempts have not simplified the forming of electrical connections to the extent desired, particularly for small diameter wires.
SUMMARY OF THE INVENTION The present invention is generally summarized in an electrical terminal including a strip of electrically conductive material having a first edge and a ductile member extending from the first edge, the ductile member having a second edge adapted to have a lead wire wrapped therearound and being bendable to be clamped against the first edge whereby the second edge of the ductile member is deformed to accomodate the lead wire.
The present invention is further generally summarized in a method of forming an electrical connection including the steps of wrapping a lead wire around the edge of a ductile member extending from an electrical terminal, and bending the ductile member against an adjoining edge of the electrical terminal to deform the edge of the ductile member to accommodate the lead wire.
Accordingly, it is a primary object of the present invention to facilitate the forming of electrical connections without requiring soldering or the like.
Another object of the present invention is -to construct an electrical terminal with a ductile member extending from an adjoining edge thereof such that a permanent electrical connection can be formed by simply wrapping a lead wire around the ductile member and bending the ductile member to abut the adjoining edge and deform the ductile member to accommodate the lead wire.
A further object of the present invention is to construct an electrical terminal having a pair of ductile ear members extending therefrom and adapted to have lead wires wound therearound, the ear members being bendable to clamp the lead wires eitheragainst each other or against edges of shoulders formed on the electrical terminal.
The present invention has an additional object in that a ductile member of an electrical terminal has a wedgelike configuration to prevent a lead wire wound therearound from slipping off the ductile member and to facilitate the winding of the lead wire near a base portion of the ductile member to assure sufficient deformation of the wire and the ductile member when the ductile member is clamped against the electrical terminal.
Yet another object ofthe present invention is to provide amethod of forming an electrical connection requiring only the wrapping of a lead wire around an edge of a ductile member extending from an electrical terminal and bending the ductile member against an adjoining edge of the electrical terminal to deform the ductile member and accommodate the lead wire.
Some of the advantages of the present invention over the prior art are that a permanent electrical connection can be formed without requiring soldering or the like, wires of small diameter and wires that are difficult to solder can easily be pennanently connected with the electrical terminal, contamination of components from soldering rosin or acid is eliminated, more than one lead wire can be attached to the electrical terminal, the electrical connection is highly resistant to vibration, the method of forming the electrical connection can be easily automated and the electrical terminal can be stamped and therefore is inexpensive to manufacture.
Other objects and advantages of the present invention will become apparent from a description of the preferred embodiment taken in conjunction with the accompanying drawings.

FIG. 2 is a side view of the electrical terminal of FIG. 1.
FIG. 3 is a broken top plan view of the electrical terminal of FIG. 1 having a lead wire wound around one of the ductile ear members extending therefrom.
FIGS. 4, 5 and 6 are broken top plan views illustrating various electrical connections formed with the electrical terminal of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT An electrical terminal 10 according to the present invention, as illustrated in FIGS. 1 and 2, is formed of a flat strip 12 of electrically conductive, ductile material sufficiently soft to set when deformed. The strip 12 has a shank 14 extending from a tapered end 16 with a pair of rectangular tabs 18 extending from opposite side edges thereof, an aperture 20 being centrally disposed in the shank 14 between the tabs 18 and tapered end 16. Shank l4 joins a neck 22 at a pair of sloping lugs 24 extending from opposite sides of the shank and aligned with a centrally disposed aperture 26, and neck 22 terminates at a pair of shoulders 28 and 30 having edges 32 and 34 angularly oriented relative to the longitudinal center of strip 12. A pair of ductile ear members 36 and 38 extend from edges 32 and 34 of shoulders 28 and 30 and have outer edges 40 and 42 angularly oriented relative to the longitudinal center of the strip joining edges 32 and 34 at an apex, respectively. Ears 36 and 38 have inner edges 44 and 46, respectively, meeting at an apex aligned with the longitudinal center of strip 12, the inner edges 44 and 46 having included angles with the longitudinal center of the strip less than the included angles of outer edges 40 and 42, respectively, such that the ears 36 and 38 each have a wedge-like configuration with ends 48 and 50 wider than the narrower base portions joining the ears with shoulders 28 and 30. t
In use, a lead wire 52 to be electrically connected to the terminal is wound around one of the ductile ears, for instance, ear 36 as illustrated in FIG. 3. The
As is shown in FIG. 4, a plurality of lead wires can be connected with electrical terminal 10 by wrapping the lead wires around both ears 36 and 38 and bending the ears against shoulders 28 and 30. By slanting the edges 32 and 34 of the shoulders toward the longitudinal center of the strip 12 in opposite directions relative to the slanting of the outer edges 40 and 42 of the ears, when the ears 36 and 38 are bent against the shoulders 28 and 30, respectively, the angular orientation of the inner edges 44 and 46 of the ears relative to the longitudinal center of the strip will cause the inner edges to be disposed in a line transverse to the longitudinal center thereby providing a regular and compact configuration for the electrical connection. The protruding orientation of the shoulders 28 and 30 position the edges 32 and 34 thereof at positions to cooperate with the edges of the ears 36 and 38; however, the shoulders can be disposed with any desired configuration to accommodate two or more ductile ears.
The bending of the ductile ears around which lead wires are wound against any of the edges of the electrical terminal 10 clamps the lead wires to deform the ductile ears at the edges thereof to permanently fix the lead wires to the electrical terminal. The wedge-like configuration of the ears 36 and 38 with the ends wider than the base portions prevents the lead wires from slipping off of the ears either before or after the ears are clamped against an opposing edge and, further, serves to facilitate positioning of the wire at the base portions of the ears to assure sufficient deformation of the wire and the electrical terminal.
A method of forming an electrical connection according to the present invention, thus, requires only the steps of wrapping a lead wire around one of the ductile ear members extending from the electrical terminal 10 and bending the ductile member against the electrical terminal to deform a portion of the ductile member and permanently fix the wire to the electrical terminal:
The electrical terminal 10 can be easily and inexpensively formed as a stamping of any suitable electrically conductive, ductile material, such as steel with a tinzinc plating, and the strip of material forming the electrical terminal can have any desired configuration conforming to the requirements for a desired application as long as the terminal has a portion defining an edge against which a ductile member extending from the terminal can be clamped after a lead wire is wrapped therearound such that the edge of the ductile member is deformed to accommodate the lead wire. That is, the configuration of the shank portion is designed to permit the electrical terminal to be secured to an electrical appliance; and, thus, the apertures and lugs can be positioned at any place and in any number desirable for a specific application. While only the edge around which the lead wire is wrapped is illustrated as being deformed during clamping of the ears against adjoining edges of the electrical terminal, the adjoining edge and the lead wire, to some extent, can be deformed during clamping to accommodate the lead wire. The ductile nature of the ears permits the edges thereof to set after deformation; and, thus, in order to increase permanence of the resulting electrical connection and to decrease costs, the electrical terminal 10 is advantageously integrally formed of a single strip of electrically conductive ductile material.
Inasmuch as the present invention is subject to many variations, modifications and changes in detail, it is intended that all matter described above or shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
