SOCKET PLUG Filed se i. 23 1925 WITNESS I ATTORNEY Patented Nov. 14, 1933 STATES SOCKET PLUG Charles Panfilo Presutti, Newburgh, N. Y.
Application September 23, 1929 Serial No. 394,721
1 Claim.
This invention relates to socket plugs for electric circuits, an object being to provide a male plug member which is connected and arranged so that the conductor wires when released, will be separated, and short circuiting of the plug will thus be prevented.
Another object of the invention is the provision of a novel form of contact element by means of which strain upon the wire at the terminal contacts will be relieved, so that danger of a broken or poor connection at these points will be practically eliminated.
With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.
In the drawing:.-
Figure 1 is a sectional view of the invention.
Figure 2 is an inner end view.
Figure 3 is a sectional view at rightangles to Figure 1. I
Figure 4 is an edge view of one of the contact elements.
Figure 5 is a perspective view of the same illustrating the manner of securing the conductor wire to said element.
Referring to the drawing in detail wherein like characters of reference denote corresponding parts, the reference character indicates the body of the male member of a socket plug. This member is formed of insulating material and is preferably shaped as shown. 35 The inner end of the male member 10 is provided with a recess 11 and extending from this recess is a socket 12 with which communicates the inner ends of openings or passages 13. These openings or passages 13 receive conductor wires 14 which extend into the recess 11 for connection with terminal plates 15.
The plates 15 are of like construction and have extending from one end a headed anchor stud 16 which is embedded in the body 10 as shown in 45 Figure 2 of the drawing. Extending from the plate 15 is a blade 1'? which may be removably positioned within the female member (not shown) 01! the plug. The plate15 carries a terminal screw 18 which provides means for attaching the inner ends of the conductor wires 14.
In order to relieve strain at the inner or attached ends of the wires 14 so as to prevent loose terminal connection 18 will not be subjected to strain by a. pull upon the conductor wires.
Extending into the socket 12 is a projecting portion 22 which is arranged between and separates the ends of the conductor wires 14, so that in the event of disconnection, danger of short circuiting through contact between these wires will be prevented. The openings 13 extend inward and are inclined relatively, and the recess 12 pro-- vides an enlarged outlet at the inner ends of these openings for the accommodation of the hooks 19 and the knotted portions of the conductor wires.
The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.
Having described the invention what is claimed A socket plug comprising a body having a recess in one end terminating into a chamber, a projection located centrally of the chamber and terminating short of the recess, plates abutting the inner wall of the recess and projecting laterally across the mouth of the chamber and spaced from each other, headed pins carried by the plates and embedded in the body, contact blades on the plates and extending outwardly of the recess, said body having conductor passages extending therethrough and communicating with the chamber at opposite sides of the projection, and hook shaped elements formed on one end of said plates and extending into the chamber on opposite sides or the projection and in the opposite direction to the contact blades and adapted to have conductors after passing through the passages wrapped and knotted thereabout to relieve strain on the electrical connections between the conductors and plates.
