lApplication filed .Tune 24,

My present invention relates to means for connecting cord terminals to complete an electric circuit as through a telephone plug or the like, and will be best understood from the following description and the 'appended drawings, in which Fig. 1 is an exterlor View of a telephone plug which I have adopted for purposes of illustration; Fig. 2 is a view similar to'Fig. 1, with the outer plate of the plug removed; Fig. 3 is a side elevation of Fig. 2; `Fig. 4 is a section on the line of Fig. 2, looking from above, but with the right-hand holding member in disengaging position, and Fig. 5 is an enlarged view of the terminal used in the illustrative embodiment. Like reference characters indicate like parts in the several views.

In the Aillustrative arrangement, a tele` phone plug 10 of the usual type and having a double terminal is provided at its upper end -with contact cups 11 insulated from each other and each connected to one of the terminals in the plug/*inthe usual manner *l The contact member 11 is provided with a central opening in which may extend the lower portion 12 of the terminal of a cord.

" (m13, this terminal having a sleeve 14 at .its

upperl end into` which the end of the cord is entered and soldered in the usual manner to form a connection. The sleeve 14 preferably is` flared out somewhat, as at 15, both 1922. serial No. 570,657.

to permit the passage of the 'sleeve 14 and 1s provided at its outer end with a push-button 22whi'ch, preferably, will be made of some insulating material. The holdingo member 19 is positioned so that normally 1t stands as shown in Fig. 2, the left member 19 having the center of the opening 21, to t-he left of the axis of the opening 18 and the center of the contact member 11. In this position, the edge of the opening 21 is adjacent the cord 13 and also extends over the extended portion 15 of the sleeve 14. Preferably, the opening 21 will be extended to merge into a recess 23 of substantially the same diameter as the cord 13, so as to fit around the cord when inthe engaging position. By pressing against the button 22, the member 19 is moved to the right (or left) 1n Figi 2 until the center of the opening 21 coincides with the axis of the opening 18, whereupon the cord 13 and .its terminal 14 can be withdrawn. Unless this occurs, theterminal is held in engagement with the contactfmemberbyY the pressure of the holding member 19 and by its overlying the end of" the sleeve .14.

The arrangement described provides a. means by whichl a cord connecter can be connected.l or disconnected from the contact member readily, and yet is held in engage- 8l ment with the contact member against conslderable longitudinal pull on the cord.

to prevent thggci/ittiXng of thefcord oygrtlienllllll f9mllrated, I have shown Ia e/dge of the/sleeve and also Yfdia purpose to be more specifically pointed out hereinafter. The plug 10 with its contact members 11 is A held in the usual divided insulating casing 1,ethe-two\halves beingheld 4togetherY by the usual screw 17. In axial alinement with the opening in the contact member 11 is a terminal opening 18 in the casing 16, this opening being large enough to permit the passage of the cord and terminal, and particularly the extended portion 15 of the sleeve 14. The end 12 of. the terminal passes through the opening in the contact member 11.

In. the form shown, I provide a holding member which consists of a flat metal'spring member 19-bent so that its `lower end .is fastened under the nut 20 of the plug 10, and bent again vat its upper end so as to pass across the axis of the c ord 13 when the terminal thereof is engaged with the com tact member 11. The holding member 19 is provided with anA opening 21 large enough double connecter so tlit ard may be con-A nected to each of the terminals ofthe plug 0u 10, the arrangement on either side of the center line of the plug being the same.

While I have shown my arrangement in connection with a telephone plug, it will be understood that it ma arrangement where it 1s desired to form an electric contact which may be'readily disconnected, and yet which is held against displacement until disconnection is desired. It will also be obvious that the embodiment of my invention may be widely varied.
