coNNnc'rIoN PLUG.

Application led March 15, 1924. Serialllo. 699,417.

cuit terminals can be quickly attached, andA after the terminals are in place, they are prevented from being accidentally withl drawn by strains or jerks on the conductors connected to the terminals.

Another object of m invention is to provide a plug whichw' l make good contact with thereceiver orv conductor terminals, all

20 of these cooperatin parts bein completely protected in a cham r of the p ug.

It is another object of my invention. to provide a plug which contains the previously mentioned features and in addition one that 25 is easy to manufacture and a plug that is strong and durable.

Other objects will be further a parent after a study of the specification an drawinannexed heretoin which:

an igure 1 is a sectional view on the line 1/1 of Fi 2 with the conductor strain clip remove v Figure 2 is a side view of the assembled pliig, while an igure 3 is a plan view; and

Figure 4 is an enlarged view showing the manner of attaching the conductor strain.

cli to the plug.

fn the drawing, 1 and 2 are duplicate o parts, preferably of a mouldedl insulating material, depressions 3 being moulded in each piece and the two pieces fastened together in any suitable manner as by rivets 4, three being shown for this purpose. The

w two depressions 3 in each part 1 and 2 form a chamber within which the springs 5 and 6 are mounted, the sprin 6 being fastened to the end of the cylin rical member 7 by spinning the end of the member 7 over and a@ Soldering the spring 6 thereto. The member 7 has an annular flange 8 fitting iu an annular space that communicates with a semicirculai opening for the member 7 that is moulded in each of the parts 1 and 2, so

Y other thereby moving that it will be seen that the annular flange 7 assists in locking the cylindrical member 7, which constitutes one of the conductors of the plug, securely to the handle. The spring 5 is insulated from the spring 6 by an insulator 9, having preferably anintegral collar 10 whichextends into the end of the cylindrical member 7. Spring 5 has a conductor pin 11 riveted and soldered thereto and extends through the tubular member 7, being insulated at the outer end by the insulators `12 and 13 and a tip ball shaped member 14 is screwed onto the threaded end ,of .the member 11, drawing the parts securel into position. The handle is rovided wit orifices leading into the cham er at the opposite end from the plug portion and each of these orifices is formed with

shoulders

15 and 16. The orifices are of a size to easily permit the passage therethrough ofthe

terminals

17 and 18 that are connected to the

insulated conductors

19 and 20. As the ends of the terminals, which are shown in dotted position Fig. 1, engage the spring members 5 and 6, they are caused to tilttoward each the ends of the terminals over the

shou ers

15 and 16, formi alocking means which prevents strains an jerks on the

conductors

19 and 20 from accidentally withdrawing the terminals from contact with thepsprings 5 and 6. These springs are formed so as to give considerable area of contact with the terminals.

In order to touching each ot er as they are tilted by the springs, a partition 21 of insulating material revent the terminals from Iis preferably moulded ineach of the members and 2. A hole for a rivet 4 being also provided at the 'unctio'n of the partition with the end of t e material of the handle members land 2. A recess 22 is moulded at the base of the partition and this recess is provided with shoulders 23, and in this' shouldered recess the anchor end 24 of a strain clip 25 is placed before the parts 1 and 2 are fastened together. Clip 25 has a hole 26 which is used for attaching -the strain cord that carries the

conductors

19 and ,20.

tapped holes required in the construction of this plug except that in the ball or tip and that all that is necessary to make connection is to slip the

terminals

19 and 20 into the oriices provided and they are automatically It isseen that there are no screws or moved to locking position. If lit is desired to disconnect the, terminals from the plug, the

conductors

19 and 20 are drawn toward each other, which causes the ends ofthe terminals to pass from off the shoulders, l5 and 16 and allowing the terminals to be withdrawn. In other words, to make connection with this plug no tools are required and the plug in operation does not have to be opened u to make any connections, thereby allowlng the lug to be transferred to another set of con uctors or another receiver ver quickly.

While have shown one form of carrying out these advantageous features, it will be readily perceived that the details of the construction may be varied without departing from the spirit of my yinvention and the scofpe of the appended claims.
