MILTON A. LIPTON BY M MW United States PatentO CONNECTOR FOR JOINING THE ENDS OF FLEXIBLE INSULATED WIRES Milton A. Lipton, West Long Branch, N. J., assignor to the United States of America as represented by the Secretary of the Army Application March 28, 1952, Serial No. 279,201
4 Claims. (Cl. 339-105) (Granted under Title 35, U. S. Code (1952), see. 266) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without payment of any royalty thereon.
This invention relates to wire connectors and more particularly to a device for making an electrical connection between flexible insulated wires.
In certain situations, particularly under battle conditions, a wire conductor is required with which armed forces personnel can connect field wire rapidly, preferably without the use of tools. that it is utilizable in all kinds of climate, simple to use, durable, and will not cut the insulation of the wires it is connecting. Other possible characteristics such a wire connector should possess are cheapness of manufacture and reusability.
Heretofore, the wire connectors in use for such purposes have tended to be impractical for field use because of varying defects such as easy breakage, lack of reusability, tendency to cut the insulation upon the wire and difliculty in manipulation.
It is therefore an object of the present invention to provide a wire connector which can be used to connect field wire rapidly and easily.
It is a further object to provide a wire connector which is durable, not subject to breakage, and usable under all climatic conditions.
In accordance with the present invention, there is provided a device for making an electrical connection between wires comprising a body member having a longitudinally disposed notched portion therein. A bore extends longitudinally through this body member, each end of said bore being adapted to receive the discrete ends of the respective wires to be connected. Means for effecting an electrical connection between said wires is provided within said bore. Each end of the body member adjacent the notched portion is provided with longitudinally disposed apertures to position the respective wires to be connected and projections extending from the surface of the notched portion of the body member are provided around which the wires to be connected can be wound, thus securely anchoring them.
Also, in accordance with the present invention, there is provided a device for making an electrical connection between wires comprising a cylindrical body member having a longitudinally disposed notched portion therein. A bore extends longitudinally through this cylindrical body member, each of its ends being adapted to receive the ends of the respective wires being connected. Means for effecting an electrical connection between said wires is provided within this bore. In each end of the body member adjacent the notched portion, there are two longitudinally disposed slots substantially co-linear with the surface of said notched portion separated by a longitudinally disposed projecting finger between them so that the wire to be connected may be positioned in one slot, wound around this finger, and brought back through the other slot. A rotatable split ring is positioned around each end of said body member, each of said split rings having suf- This connector should be such- "ice ficient circumferential gap for readily positioning the wires in the aforementioned slots. With wires in position, the split ring may be rotated to lock the wires positioned in the slots.
For a better understanding of the invention together with other and further objects thereof, reference is to be had to the following description taken in connection with the accompanying drawings in which Figure 1 is an isometric drawing, partially cut away, illustrating a preferred embodiment of the invention with the slots uncovered and Figure 2 is an end view of Figure 1 with the wires locked in position by the split ring.
Referring now to Figure 1, there is shown a wire connector comprising a cylindrical body member 1 having a longitudinally disposed notched portion 2 and a bore 3 extending longitudinally therethrough, the ends 4 and 5 of this bore receiving the respective ends 6 and 7 of the wires 17 and 18 to be connected. Within this bore, there is shown a means for effecting the electrical connection between the wires, said means in this embodiment being a metal pin 8 pointed at both ends as shown. In the respective ends 9 and 10 of the body member adjacent the notched portion 2 there are longitudinally disposed slots such as 11 and 12 substantially co-linear with the surface of the notched portion in which the respective wires are positioned. The wires are wound around fingers 13 and 14 which separate said slots. Rotatable split rings 15 and 16 are circumferentially positioned around the ends 9 and 10 of the body member and are utilized to lock the respective wires 17 and 18 in position in the slots. Said rings have suflicient circumferential gap to provide ready access to the slots.
Referring to Figure 2, wherein an end view of the connector is shown with the split ring rotated so as to be in a locking position, there is shown wire 17, the end of which has been inserted into lonigtudinalbore 3, positioned in one slot 11, wound about the projecting finger 13 and brought back through the other slot 12. The split ring 15 is shown rotated into a position where it covers slots 11 and 12, thus securely positioning the wire 17.
Considering now the operation of the wire connector, the end 6 of a wire 17 to be connected is inserted into the bore 3 extending longitudinally through the body member 1 until it makes contact with the pointed end of the metal pin 8 within the bore 3. The wire is then positioned in slot 11 in the end of the body member 9 adjacent the notched portion 2, wound about the projecting finger 13 and brought back through the slot 12. The other wire to be connected is affixed in the same amnner on the other end of the body member. In this manner, two wires are electrically connected by means of their respective ends making contact with the ends of a metallic pin and are firmly positioned so that this connection is of a secure nature.
The wire connector described hereinabove is a simple, eflicient device, easy to use, and reusable. The material used in its manufacture can be any material of a durable nature such as metal, ceramic, molded plastic, etc. Inasmuch as the wires pass back and forth through the positioning apertures and are anchored by being wound around a finger, a hook, or other projecting means, all the physical strain is taken up at this point and the connection of the end of the wire with the end of the metallic pin within bore remains secure.
While there has been described what is at present considered to be the preferred embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention and it is therefore aimed in the appended claims to cover all such modifications as fall within the true spirit and scope of the invention.
