This invention has to do with devices for making electrical connections, and, more particularly, devices of the spring connecter type; Specifically, the invention is directed to improvements in connecting plugs of the telephone type espeilally adapted for easy connection and disconnection to and from the terminals of a telephone cord or the like. a At the present time the'invention finds its most important embodiment in telephone plugs for use in conjunction with radio apsairatus. Radio telephone headsets are orinarily provided with conductor cords having so-called pin type cord tips, which,
of .course, are not adapted for making connections with spring jacks but are well adapted for making connections with certain types of binding posts and spring clips such as the well-known Fahnestock clips.
Because of thefact that it is frequently de- ,sirab'le to connect a telephone headset with binding posts and the like, especially for experimentalv and testing purposes, it is undesirable, in many cases, to have the headset permanently connected to the plug. The
structure of the present invention is designed to meet this situation in that it provides a plug to which a cord provided with 'the usual pin type cord tips can be quickly and easily connected and disconnected and in which the entire mechanism for effecting such connections is mounted inside the handle of the plug.
626,285, filed March 20, 1923 and Serial Nd; 618,887, filed February 1 4, 1923, telephone plugs adapted for connection with telephone cords provided with pin type cord tips are disclosed. The present invention is in certain respects, an improvement on the plugs described in the aforementioned copending applications. 1

combining extreme simplicity and correassemble the handle in orderto connect or bly of-the handle, but it is somewhat more expensive to manufacture than the former.
Plugs in accordance with the present invention combine the advantages of both the aforementioned plugs in that they are little,
,if at all, more expensive to manufacture than the first and are substantially as convenient as the latter from the standpoint of ease in connecting and disconnecting the cords.
The plug constituting the preferred embodiment ofthe present invention comprises the usual coaxial tip and sleeve conductors to each of which is connected a conducting member in theform of a leaf spring having its free end portion apertured to receive a pin type cord tip of the standard size. A two-piece hollow handle of insulating material is provided inside of which the con- ,dircting members are disposed. Each of the two parts of the handle is provided with a slot of such shape as to define a hook-shaped projection or shoulder integral with the handle. These slots are respectively disposed adjacent the free end of one of the conducting members, andeach is so proportioned as to permit the insertion therethrou'gh of a pin type cord tip into the aperture in the associated conducting member and to further permit manipulation of the cord tip into a position inside the hook of the shoulder wherein the cord tip is gripped bythe conducting 'fnember and shoulder conjointl When thus inserted the cord tips are firm y held and cannot be withdrawn by a direct pull on the cord. They can, however, be
readily disconnected by a reverse manipul.
