BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a molded housing of suitable, non-conductive material encasing and segregating a plurality of spring-loaded terminal connector tabs that embody stab connections to receive wire in the rear of the housing for the purpose of conducting current through the insulated terminal tabs to an identical yet inverted hermaphroditic mate for the purpose of connecting wire to wire, fixtures, series harnesses and the like.
2. Description of the Prior Art
Hermaphroditic connectors provide reliable means for connecting and disconnecting a plurality of electrical conductors. The manufacturing advantages are obvious in that one piece serves as both pieces of a connective set. Previous patent examples attest to the practicality of manufacture, functionality of use and varied applications of hermaphroditic connectors. See Gettig, et al., U.S. Pat. No. 4,963,102, and Rudoy, et al., U.S. Pat. No. 5,800,196.
The preceding references depict hermaphroditic connectors with similar features to each other. Most of the connectors are configured to be factory wired with molded entry rears or at best require the use of a separate “crimp” type conductive terminal with a blade extension to be inserted into the harness at time of use. The most obvious difference distinguishing the present invention from the prior art is the embodiment of low pressure “stab” connectors located at the rear of the housing. This allows for the fast reliable and field operable attachment of wire to connector.
OBJECTS OF THE INVENTION
An object of the present invention is to provide for a novel hermaphroditic connector or coupling which permits connection of a plurality of wire to wire connections, wire to fixture connections, or series harness connections.
A further object of the present invention is to provide for a novel hermaphroditic connector which allows for fast and secure connection requiring low insertion force.
A still further object of the present invention is to provide for a novel hermaphroditic connector which facilitates multiple wire connection which facilitates quick and positive multiple wire connections which are easily releasable if so desired.
A still further object of the present invention is to provide for a novel hermaphroditic electrical connector which provides for a plurality of stab connectors and parallel communication with each other within the hermaphroditic connector which facilitates quick, positive connections which are easily releasable if desired.
SUMMARY OF THE INVENTION
A molded housing of suitable, non-conductive material encasing and segregating a plurality of spring-loaded terminal connector tabs that embody stab connections to receive wire in the rear of the housing for the purpose of conducting current through the insulated terminal tabs to an identical yet inverted hermaphroditic mate for the purpose of connecting multiple wires to multiple wire to wire connections, wire to fixture connections, or series harness connections and the like.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an exploded view of a first hermaphroditic mate member 10 and FIG. 2 is an exploded view of a second inverted hermaphroditic mate member 12 which when mated form a coupling housing 13 as illustrated in FIG. 4. First and second hermaphroditic mate members 10 and 12 are of identical construction and when one is inverted, they snap fit together to form a positive electrically conductive connection 13. This will be apparent when considering the exploded views of first hermaphroditic mate member 10 and second inverted hermaphroditic mate member 12 as illustrated in FIGS. 1 and 2. First and second hermaphroditic mate members 10 and 12 are defined by top wall 22, bottom wall 24, and end wall 26 and opposing side walls 30 and 32, top wall 22 having an extending latching member 28 as will be described hereafter. Disposed between opposing side walls 30 and 32 are a series of rib members 40 which define a series of channels 42 within first and second hermaphroditic mate members 10 and 12. The channels 42 defined by the rib members 40 are for receipt of conductive stab connectors 44. Not shown in FIG. 1, but illustrated in FIG. 4, the end wall 26 of hermaphroditic mate members 10 and 12 have a plurality of apertures 56 for the insertion of wire. The stab connectors 44 are secured within the hermaphroditic mate member 10 such that an apertures 60 in each of the stab connectors 44 (See FIG. 6), are alignable with a respective apertures 56 in the end wall 26 of the hermaphroditic mate member 10.
Hermaphroditic mate member 12 as illustrated in the exploded view of FIG. 2 is the inverted version of hermaphroditic mate member 10. It secures between its ribs 40, a plurality of like stab connectors 44 identical to the stab connectors 44 of hermaphroditic mate member 10 except that they are inverted. Apertures 60 on stab connectors 44 of hermaphroditic mate member 12 are alignable with apertures 56 in the end wall 26 of the hermaphroditic mate member 12. Hermaphroditic mate member 10 and inverted hermaphroditic mate 12 are secured by their respective latching members 38 and a recessed slotted keeper 70 on their respective bottom walls 24. FIG. 4 illustrates the hermaphroditic mate member 10 and inverted hermaphroditic mate member 12 in a mated and locked position.
Each stab connector 44, as illustrated in FIG. 6 consists of a longitudinal web portion 80 having a first end 82 folded upon the web portion 80 so as to form an acute angle which constitutes a conductive terminal end 84. The opposing end 86 of web portion 80 is folded or bent a series of times to the same side of the web 30 as the first end 82 such that the second end 86 is distal proximate the web portion 80 forming gap 88 which forms the stab connector. The bending of the stab connectors 44 provides appropriate spring tension to both ends allowing usage thereof with hard wire found in the internal wiring of a structure as well as braided wire utilized in fixtures.
As better can be understood from FIG. 5 which is a cross sectional view of FIG. 4 along its longer axis, when hermaphroditic mate member 10 and inverted hermaphroditic mate member 12 are in a locked and mated position, the terminal portion 84 of stab connectors 44 of hermaphroditic mate member 10 are in contact with the terminal portion 84 of stab connectors 44 of inverted hermaphroditic mate member 12. Therefore, when a wire 90 is inserted through an aperture 56 in hermaphroditic mate member 10, it passes through an aperture 60 in stab connector 44, contacts the bent end 86 of the respective stab connector and is directed into the gap 88 and secured. When a similar wire 92 is inserted through the corresponding aperture 56 in the opposing inverted hermaphroditic mate member 12, it is directed in a similar manner by the stab connector in order to secure the wire. The two wires 90 and 92 are now in electrical communication as a result of their contact with their respective stab connectors and the fact that the terminal ends 84 of the stab connectors are in abutting relationship.
Hermaphroditic mate members 10 and 12 are identical and when one is inverted, the two of them mate as illustrated in FIG. 4. They are constructed of a suitable insulative, non-conductive material. The vertical ribbing members are formed unitarily with the hermaphroditic mates and are of the same material so as to insulate adjacent stab connectors and prevent arcing, corona discharge or water born shorting. The conductive terminal ends 84 of the stab connectors protrude slightly beyond their respective hermaphroditic mate members 10 and 12 which facilitates positive, spring tensioned, conductive contact with the opposing conductive terminals when the hermaphroditic mate members are engaged in the locked position.
The embodiment illustrated in FIGS. 1 through 5 represents three stab connectors associated with each hermaphroditic mate member. It will be recognized by those of ordinary skill in the art that depending upon the wiring requirements, a hermaphroditic coupling of the type disclosed herein may be constructed in which fewer stab connectors or more stab connectors may be secured within a hermaphroditic coupling designed to accommodate same without departing from the spirit and scope of the invention.
While the present invention has been described with respect to the exemplary embodiments thereof, it will be recognized by those of ordinary skill in the art that many modifications or changes can be achieved without departing from the spirit and scope of the invention. Therefore it is manifestly intended that the invention be limited only by the scope of the claims and the equivalence thereof.
