The insulator bodies 22 and 24 when molded around the ends of the leads L and adjacent carrier strip portions, as shown in FIG. 3, are relatively movable about the hinge means 26 and intermediate carrier strip portion 100 from the position shown in FIG. 3 to the position shown in FIG. 5 and latched together by the cooperable latching means 30 and 32 so as to orient the various leads in the proper direction.
As shown in FIG. I, the metal carrier strip comprises an elongated, planar thin bendable metal carrier strip having a relatively small width. The metal carrier strip 10 can be made of any material which has good electrically conducting properties. The metal carrier strip 10, crimping flanges l2 and webs 14 would be blanked out of strip stock and the crimping flanges would be bent upwardly, as shown in FIG. 1, by a suit able punch and die apparatus (not shown), as well known to those skilled in the art. Thereafter, the strip stock would be fed to a second suitable punch and die apparatus (not shown) where the crimping flanges 12 would be crimped around the bare ends 36 of metal leads L to securely connect the ends 36 of the leads L to the carrier strip 10, and the carrier strip about the webs 14 would be bent downwardly so that the plane of the carrier strip 10 would extend normal to or trans versely of the longitudinal axes of the ends 36 of the leads L. Also during this operation the carrier strip 10 would be cut to length depending on the number of leads that are to be connected together. When the leads L are crimped onto the carrier strip 10 via the crimping flanges 12, the leads L are electrically connected to one another.
After the leads L are crimped onto the carrier strip portion 10, as shown in FIG. 2, this subassembly is then moved into a suitable molding apparatus (not shown) wherein the insulating means is molded thereon. The insulating means 20 is made from a suitable elastic or resilient insulating material, such as a suitable rubber compound. and includes the first and second insulator bodies 22 and 24. In the embodiment shown in FIG. 3, the insulator body 22 is molded around the ends of two of the leads L and the adjacent portion 10a of the carrier strip 10. The insulator body 24 is molded around the ends of the two remaining leads L and the adjacent portion 10b of the carrier strip 10. The insula tor bodies 22 and 24 are separated by an integral hinge means 26 molded around the intermediate portion 100 of carrier strip 10.
As shown in FIGS. 3 and 4, the insulator bodies 22 and 24 completely surround the ends 36 of the respective leads L as well as the adjacent portion part of their insulator covers 38 and completely surround the adjacent portions of the carrier strip [0. Thus the bare ends 36 and adjacent end portions of the insulators 38 and 4 adjacent carrier strip portions are completely imbedded within the insulator bodies 22 and 24.
As shown in FIG. 3, the insulator bodies 22 and 24 are molded so as to be located side-by-side in the same plane, but slightly spaced from each other. As shown in FIG. 4, each insulator body 22 and 24 is generally L- shaped as viewed in cross section and includes generally planar upper and lower sides 50 and 52, generally planar side surfaces 54 and 56 and generally planar end surfaces 58 and 60. The end surfaces 60 of the insulator bodies 22 and 24 converge toward each other at 60a so as to define a reduced thickness hinge section 26, and for a reason to be hereinafter more fully described.
After the insulator bodies 22 and 24 have been molded onto the carrier strip 10 and adjacent end por tions of the leads L, the insulator bodies are relatively moved towards each other by bending the same about the hinge means 26 and intermediate carrier strip portion 100 from the position shown in FIG. 3, in which the insulator bodies lie in a side-by-side relationship and in generally the same plane to the position shown in FIG. 5 in which the end surfaces 60 are juxtaposed or lie back-to-back. The reason for the converging portions 60a of the end surfaces 60 is to insure that the two insulator bodies can be bent into a back-to-back relationship and when so bent the portions 60a define an opening 70, as shown in FIG. 5. When the insulator bodies 22 and 24 are moved to the position shown in FIG. 5, the leads L will be oriented in the proper direction.
The insulator bodies 22 and 24 are adapted to be latched together when moved to the second position, as shown in FIG. 5, by the cooperable latching means 30 and 32 on the insulator bodies 22 and 24, respectively. The cooperable latching means 32 comprises a catch member in the form of a resilient tab 72 molded integral with the insulator body 24 at its top side 50 and which projects downwardly and perpendicularly from the end surface 60, as viewed in FIG. 3. The tab 72 is relatively thin and has a central aperture 74 therethrough. The aperture 74 is shown in FIG. 3 to be circular and have a given diameter or transverse dimension when in its normal free state position.
The cooperable latching means 30 comprises a latch member in the form of a projection 75 extending upwardly and normal to the top surface 50 of the insulator body 22, as viewed in FIG. 3. The projection 75 is ofa circular cross section and is conical in shape as viewed in FIG. 4, so that its diameter progressively decreases proceeding from its end integral with the top side 50 of insulator body 22 towards its free end. The projection also includes a headed portion 78 intermediate its ends and which has an outermost minimum external diameter, when in its free state position, which is greater than the diameter ofthe aperture 74 in the catch member 72 when the latter is in its free state position.
When the insulator bodies 22 and 24 are moved from their FIG. 3 position toward their FIG. 5 position, by bending the hinge means 26 and intermediate portion 10c of the carrier strip 10 so that the adjacent end surfaces 60 are back-to-back, the insulator bodies are then moved relative to each other by twisting about the hinge means 26 and intermediate portion of the carrier strip 10c toward and from the plane of the drawings, as viewed in FIG. 5, to position the catch member 72 over the free end of the latch member 75. When this occurs, the insulator bodies 22 and 24 are twisted in the reverse direction to cause the catch member 72 to be pushed down onto and over the portion 78 of the projection 75 on the insulator body 22. As the catch member 72 engages the headed portion 78 of the projection 75, the catch member 72 will stretch to increase the diameter of the aperture 74 and the headed portion 78 will tend to contract to decrease its outermost external diameter until the catch member 72 clears the headed portion 78 whereupon the catch member 72 will return toward its normal free state position and the headed member will return towards its normal free state position to lock the catch member 72 beneath the headed portion 78 of the projection 75.
The bending of the insulator bodies 22 and 24 about the hinge means 26 and the intermediate portion of the carrier strip and the twisting movements necessary to latch the catch member 72 beneath the headed portion 78 of the latch member 75 can either be carried out by hand or by an automated assembly apparatus. It will, of course, be understood that the insulator body 22 could be molded around just one of the leads and with the insulator body 24 being molded around the remaining leads to form a connection in the manner described above. Moreover, even though in the preferred embodiment, the end surfaces 60 are located in the same parallel plane after the molding operations, as shown in FIG. 3, it will, of course, be understood that the angular relationship between the end surfaces 60 could be varied, such as by being molded to define an obtuse included angle therebetween that is less that 180 so that when the insulator bodies are moved to position the end surfaces 60 back-to-back, the leads L can be oriented in any desired direction.
Although the novel electrical connection of electrical leads L of the present invention could be used in various types of applications, it is especially suitable for use in automotive wiring harnesses wherein a connection or splice is needed into the primary wiring harness to connect optional equipment. For example, one of the electrical leads could be connected via connectors to a power source and the other electrical leads connected via connectors to individual lights in the automobile where extra lights are provided as optional equipment.
From the foregoing, it should be apparent that the novel electrical connection and the method of connecting electrical leads together is relatively simple and permits the use of of automated assembly equipment.
Although the illustrated embodiment hereof has been described in great detail, it should be apparent that certain modifications, changes, and adaptations may be made in the illustrated embodiment, and that it is intended to cover all such modifications, changes and adaptations which come within the spirit of the present invention.
