Description

y 1955 R. K. BILSBOROUGH 2,713,154
ELECTRICAL CONNECTOR Filed June 18, 1954 INVENTOR.
ROY K. BILSBOROUGH ATTOR N EYS 7 member.
United ELECTRECAL ooNNnoToR Roy K. Bilsborough, Warwick, R. I., assignor to PattonlvIacGuyer Co., a corporation of Rhotle Island This invention relates to coupling devices for electrical conductors and the like and more particularly to an improvement in electrical connectors in which interengaging members can quickly be brought into connecting relation with each other and as quickly disconnected when desired.
An object of the invention is to provide an electrical connector which will mate with a similar connector and thus obviate the need for a male and female unit.
A further object is to provide a simple and economical unit which will be formed of one piece with one or more parts thereof being held together under tension.
A still further object of the invention is to provide a cable connector which will be adapted to be engaged with a similar unit by laterally sliding the two connectors together so as to resist pulling the connectors apart longitudinally by tensions applied to the conductors themselves.
With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.
In the accompanying drawings:
Figure 1 is a plan view illustrating a pair of connectors locked together;
Figure 2 is a sectional view taken on lines 2-2 of Figure 1;
Figure 3 is another plan view of the connectors interlocked taken from the reverse side of that of Figure 1; and
Figure 4 is a detached perspective view of two connectors in a position to be interlocked one with the other.
In proceeding with the invention, 1 preferably form, by stamping from a suitable conductive material such as copper, brass, or the like a blade portion and a wire interengaging portion of a general outlined shape as shown in the drawing. Suitable dies may be provided by which the connector may be formed with its fingers and oifsets as shown more particularly in Figure 4 to provide a unitary structure.
With reference to the drawings, 1 show my improved connector which may be considered as having two portions, 5 designating the cable connecting portion and 6 designating the blade portion. The cable connecting portion 5 may take any form but is herein shown as comprising a pair of ears 7 and 8 which are adapted to wrap around the insulation and the conductor portion of the wire, respectively, so as to maintain a good physical as well as electrical contact. The blade portion 6 of the connector consists of a generally flat piece of electrically conducting material and is provided with a finger 11 which is cut out of the body portion 6 and is pressed outwardly thereof, being otfset as at 12 where it joins the body The finger 11 is preferably spaced from the body member a distance equal to the thickness of the material of which the body member is formed. Intermediate in the longitudinal dimension of the body member the latter is ofiset as at 13 with a double bend sub- 0 stantially the thickness of the body member, as will be seen 7 more particularly by referring to Figure 2. Substantially half of the offset portion 13 is cut away to form a slot 14 that is adapted to accept the ofiset portion 13 of a mating connector. A protuberance or pimple 15 is also formed in the body member adjacent the finger 11 to provide a function which will presently be described.
It will be apparent from the drawing that only a single form of connector need be provided embodying the features described to effect an efiicient coupling between two conductors. To join two similar connectors, they may be arranged together as shown in Figure 4 so that the slots 14 in the offset portions 13 are opposite each other. The body members may then be slid laterally so that the ends 16 thereof slide over the part 17 adjacent the wire connecting means and so that the ends 16 also slide underneath the fingers 11. As complete lateral sliding is effected, the end portion 16 engages the protuberance 15 which urges the end portion 16 into interlocking relationship with the finger 11 and resists lateral disengagement of the two connectors when slid completely together as shown in Figures 1-3. It is desirable that the protuberance 15 urge the end portion 16 against the fingers 11 so as to form a tight electrical contact therewith although it will be apparent that by properly forming the fingers 11, the protuberance 15 may be dispensed with so long as a slight deformation occurs when the end 16 is slid underneath the finger 11.
From the foregoing it will be apparent that the connectors when interengaged to form the connection shown in Figures 1 to 3 cannot be separated by a direct force longitudinally of the connection and that the only way in which they can be separated is to be slid laterally. Thus, for all practical purposes the connection is secure against accidental disconnection.
I claim:
1. In a connector for coupling electric conductors having means for engagement with a wire or the like, a die formed blade portion of conductive material, an offset extending transversely of said blade element at a location substantially midway longitudinally thereof and having half of the extent thereof slotted, a finger cut from said blade portion and ofiset therefrom to extend parallel thereto but spaced therefrom whereby said connector may be connected with a similar unit, the slotted portion of each unit interlocking with the offset portion of the other and the finger of each unit receiving the end portion of the blade element of the other unit when the units are laterally moved together.
2. A connector as in claim 1 wherein a protuberance is formed on said blade portion adjacent said finger to urge a mating connector against said finger.
3. A connector as in claim 1 wherein said finger is spaced from said blade portion a distance equal to the thickness of said blade portion.
4. A connector for coupling electric conductors having means for engagement with a wire or the like, said connector including a blade portion extending from said means, an offset extending transversely of said blade portion at a location substantially midway longitudinally thereof and having half of the extent thereof slotted whereby said connector can be connected with a similar unit, the slotted portion of each unit interlocking with the offset portion of the other when the units are laterally moved together, and means on each blade portion to hold the blade portion of the other unit in contact therewith.
