The present invention relates to improvements in cables or other electric conductor engaging terminals.
An important object of the invention is the provision of a conductor terminal'constructed so as to permit a rapid and durable connection of an electric conducting wire.
A further object of the invention is the provision of a conductor terminal designed to securely engage a conductor and to obviate the use of soldering or other connecting material.
Another obj ect of the invention is the provision of a terminal of the above character which will be simple and durable in construction and which can be conveniently adjusted to conductor engaging position.
Other objects and advantages of the in'- vent-ion will become apparent as the description progresses.
In the accompanying drawings forming a part of this speciiication and in which like reference characters are employed to designate corresponding parts throughout the same: f
Figure 1 is a perspective view of the improved terminals operatively mounted upon a supporting base and engaging an electric conductor,
Figure 2 is a fragmentary perspective view of one of the terminals prior to the connection of a conductor therewith,
Figure 3 is a similar view showing the initial connection of the terminals with a conductor,
embodiment o-f the invention, the numeral generally designates a conventional form of terminal base constructed of porcelain or other insulating material, the top of the base being formed with conductor engaging ms. "serial No.' 379,552.
grooves andV depressions adapted to receive therein lthe conductor securing terminals.
' One portion yof the base topis provided with an arcuate depression designed to support thereinran arcuate, substantially horseshoe shaped, terminal plate 11. An opposed recess inv the basev 10-supports a flat elon-V gated terminal plate 12.
1 Eachof the-V terminall plates 11 and 12 is provided, .at itsroutervedgefportion, with a pair of 'spaced arcuately bentv prongs 13- turned upwardly/to,V form conductor engaging projections, Between the prongs 13 is formedA a relatively long` and narrow tongue 14 spaced equidistantly between the prongs and normally assuming an upwardly bent outwardly inclined position, as shown in Figures 1 and 2.
Each of the terminal plates is also provided with an interiorly threadedl aperture adjacent the outer edge in longitudinal alignment with the tongue 14 adapted to receive therein a terminal screw embodying a threaded shank 15 and an enlarged head 16. rlhe head is formed with a diametrically eX- tending groove 17 in the top thereof disposed to receive the tongue 14 in conductor engaging position. The screw head 16 is also preferably provided with spaced notches 18 for convenient turning movement thereof.
In connecting a conductor with the terminals, the insulation is removed from a portion thereof and the uncovered wire initially positioned between the bent prongs 13 and the screw, the head of the screw being positioned in an elevated arrangement to receive the conductor wire thereunder. The screw is then threaded tightly upon the conductor wire and disposed so that the groove 17 will assume a longitudinal position in registration with the extension of the central tongue 14. The tongue is then bent'over the wire and into the groove 17 of the terminal screw to securely clamp the conductor to obviate accidental disconnection thereof.
Thus, an extremely simple and effective terminal connection is afforded, permitting rapid connection of the conductor or removal thereof without the necessity of soldering the joint between the terminal and the conductor.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the in vention or the scope of the subjoined claim.
Having thus described my invention, I claim: p l Y In a conductor terminal, a terminal bplate provided with a 'threaded 'aperture there-v through, a screw engageable with the a erture having an enlarged head dispose 4to, v
engage a conductor between the head and the plate and provided wtha diametrically'ek tending groove in thetop thereof, a pairv of upwardly curved prongs extending in spaced position from the outer edge. of the plate adaptedto prevent outward movement of a conductor -n connecting position between the screw head and the plate, and an elongated tongue projecting rom Vthe outer edge of the terminal plate between the prongs adjustable to a screw clamping position when bent over the conductory and tted longitudinally into the groove, in the screw head.
In witness whereof I have-hereunto set my` hand.. f
GEORGES BEDARD.
