TERMINAL CLIP FOR ELECTRIC CONDUCT-OBS.

Specification 0: Letters Patent. Pate ted Jan. 30, 191 '7.

Application filed February 3, 1912. Serial No. 675,284:

To all whom it may concern: Be it known that I, BENJAMIN A. Jurrnnna citizen of the United States, res1dingat' Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Terminal ()lips for Electric Conductors, of which the following is a specification.

This invention relates to certain new and useful improvements in terminal clips for electric conductors.

Among the objects of the invention is the production of'a terminal clip which may be readily and permanently secured to the end of an electric conductor, whereby provision is made for conveniently connecting said conductor with a binding post or other electrical terminal.

Afurther object is to provide means whereby the insulation surrounding the conductor may be more or less firmly grasped in retaining the clip in position,

whereby said insulation is protected by the cli further object is to construct a terminal cli of a single piece of metal.

'l he invention will be hereinafter. fully set forth and particularly pointed out in the claims.

In the accompanying drawing, Figure :l is a perspective View illustrating my irnproved terminal clip, the same being illustrated as attached to an electrical conductor. Fig. 2 is a longitudinal sectional view. Fig. 3 is a cross section on the line 3--3, Fig. 2,

a perspective view of a slight modified Riferring to the drawing, my improved comprises a ferrule 10, and a clip meme said ferrule being adapted to cum brace he insulation of an electrical conductor 125, said insulation being indicated at 13. The "ferrule is preferably formed as a cylindrical body struck up from sheet metal with longitudinal abutting edges 14, and at a point diametrically opposite said abutting edges, said ferrule is provided with an integral tongue which is bent downwardly, as indicated at 16, diametrically across the open forward end of the ferrule. Said tongue is again bent at right angles, as indicated, at 16 and extended forward to form the clip member 11. The downwardly bent portion of the tongue 15 is pro vided with a hole or opening 17 through which the bare'con'ductor Wire 12 may be,

to the tongue, as indicated at 18 The clip member is provided with'a'longitudinal slot 20, which extends approximately to the tongue 15, said slotliaving an enlarged seat portion 21, to receive an electrical terminal, a relatively narrow. entering portion being provided, leading to said seat portion from the end of the chp,'indicated at 22, said entering portion being smaller than the cross section of the conductor to be accommodated by said seat portion. When passed, the same being preferably soldered the arms of the clip member are forced apart.

by reason of a conductor passing through the entering portion 22, the tongue 15 is V caused to bow inwardly, normallyresisti-ng the scpara'tlon of said arms, and when the said conductor reaches the seat portion 21,

said tongue again flattens, thereby maintain.- ing the necessary resiliency in t1 all times and rendering the neon 1 g posts unnecessary. In'other words .nea us of the clip must be spread apart henna. he clip can be disengaged from the connector located in the seat portion 21,v andsuch spreading movement being resisted b the tongue 16, insures against accidental gagenient of the clip and conductor.

In practice, when it is desired. to connect my improved terminal with a conductor, the Wire is skinned by removing a portion-of the insulation 13, and the ferrule-10 is then passed over the end of the bare wire and th adjacent insulation, the Wire protruding through the opening 17. The ferrule fits 1 more or less snugly over the insulated por-.

tion of the' conductor, aiding in retaining the clip in position and at thesame'time protecting the insulation adjacent the bare wire.-

isen- The protruding end of the conductor is then v dered, as above described.

In Fig. .t I have shown a slight modification which consists in providing the clip with wings 19 which may be bent around the bent back. against the tongue 15 and sol:v

end of the conductor to closely clasp the-lat ter. In some classes of workthis form is preferable to the cylindrical ferrule, but in all other particulars this form of clip is,

of the forms in which it may made,-or

'iybstantia y {parallel i tongue all ofthe forms of its use, what I claim is "1. A terminal cli for electrie conductors cpmprisin a ferruiiz and a clip portion in planes, connected by bent over one end of the ferrule portion, said clip portion and tongue being of sheet metal, said cli portion being provided with a longitudinal slot leading n.

fproximately to the tongue'to provide amt,

angle thereto, also of sheet metal, said clip being provided ing diametrically the reacross, said tongue terminating in anintegral cllp bent at an said tongue and clip being with a longitudinal slot leading approxiniately to the tongue to provide arms, said slot having an enlarged seat portion and a relatively narrow entering portion leadlng thereto from the end of the clip, the material at the base of said arms being yieldable to permit a conductor larger than said narrow entering portion, to pass therethrough to and from said seat portion.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
