Application filed October 30, 1923. Serial No. 071,740.
The present invention relates to detachable connecters whereby a circuit Wire may be operatively connected to electric devices such as motor brush holders, spark plugs, etc.
The object of my invention is to provide an improved connecter which may be connected and disconnected from electric devices by the unskilled without the use of tools, and without danger of becoming injured by handling, which when in applied position will insure a highly eflicient contact under all operating conditions and Without fatiguing under vibrations, and which may be economically manufactured.
One form of the invention is illustrated in the accompanying drawing in which Fig. 1 is a side elevation with part insection of a well known type of electric motor with myconnecter applied to the brush holder thereof; Fig. 2 is an enlarged perspective view of a detached brush holder and connecter attached; Fig. 3 is a similar perspective with the connecter detached, and Figs. 4 and 5 are detail views showing the construction of the connecter. v
In the construction shown in the drawing, the commutator brush 1 is in the form of a prismatic block of gas carbon wbearing at one end against the motor commutator 2 and freely movable lengthwise in a metal sleeve or brush holder 3 which is threaded at its outer end for an adjusting screw 4 for varying'the pressure on the brush through its spring 5 also mounted with the brush holder: 4
The brush holder is insulatively mounted in the motor frame 6 by a cylindrical shell 7 of fiber into which it is longitudinally forced and then driven together into a suitable hole in the motor frame opposite the commutator.
The inner end of the brush holder 3 extends beyond the end of the insulating shell a peripheral groove 8 for the reception of the connecter clip'9 at the end of the lead wire 10.
' The connecter clip 9 consists of a. spring ring or loop of helically wound stilt wire, preferably phosphor bronze. the ring-or loop is such that upon being forced like a garter over the end of the brush holder 3, it will recoil sufliciently t0 hrmly engage the walls of the groove 8 and be the same time readily yieldable to permit sidewise movement of the lead wire 10 to which itis joined.
The joint between the connecter clip 9: and the teed wire .10 is shown enlarged in Fig. 4; and is made by stripping the braided insulation 11 oil the end portion of the wire which is then threaded through two or three convolutions 12 at each end of'the helical coil and then closely wrapped over the end of the braided insulation 11 to prevent it from fraying or receding. A drop of solder llapplied over the'joint serves to holdall The size of O]? FORT WAYNE, INDIANA, ASSIGNOR TO GENERAL ELECTRIC I COMPANY, A CORPORATION OF NEW YORK.
parts in fixed electrical and mechanical relation.
While I have shown and described the best embodiment of the invention known to me, I do not desire to be restricted thereto.
.What Iclaim as new and desire to secure by'Letter's Patent of the United States, 1s
1. A connecter clip consisting of a spring -a conductor wire with braided insulation having one end bared of insulation and threaded through the end convolntions of said helix and wrapped about the end of the braided insulation to bind it in place. 7
In witness whereof, I have hereunto set my hand this 24th day of October, 1923.
