DETAILED DESCRIPTION

(6) An embodiment of the present invention is depicted with respect to FIGS. 1-4 showing a cable assembly 10 including a cable transition member 20 to be attached to a connector body 40. The cable transition member 20 includes a boot 25 and cable 22. Referring to FIGS. 1 and 2, a collar 30 with a circular outer diameter 31 is placed onto an existing non-circular connector body 40. The connector body 40 has a triangular shape 42 and the collar 30 has a corresponding inner shape 34, so that mounting of the collar 30 to the connector body 40, 42 maintains the connector body 40 in a fixed angular orientation. The angular orientation of the connector body 40 may be adjusted by the placement of the collar 30 onto the cable assembly 20. The circular outer diameter 31 of the collar 30 allows for the angular adjustment of the connector/collar assembly with respect to the cable transition member 20. For example, the collar 30 (prior to attachment) may be oriented in any orientation between 1 and 360 degrees. By securing the collar 30 to the cable transition member 20 (either by insert molding the collar 30 to the cable transition member 20 or mechanically attaching the collar 30 to the cable transition member 20) the orientation of the cable 22 with respect to the connector 10 is fixed (also with respect to a host receptacle).

(7) The connector body 40, 42 may be oriented in a predetermined position with respect to the cable transition member 20 by fixing the collar 30 in the predetermined position between the connector body 40, 42 and the cable transition member 20. The connector body 40, 42 is oriented in a predetermined position with respect to the cable transition member 20. The circular outer diameter 31 shape of the collar 30 allows for orientation of the collar 30 with respect to the cable transition member 20 in a predetermined orientation via insert molding or mechanical attachment. The inner diameter shape/outer diameter 34 of the collar 30 corresponds to the rectangular or triangular shape 34 of the connector body 42 in order to fix the orientation of the connector body 40 with respect to the collar 30.

(8) FIG. 1 depicts an exploded view of the cable assembly 10 and the connector body 40, 42. The cable transition member 20 includes a longitudinal axis ‘x.sup.1’ which aligns with the longitudinal axis ‘x.sup.2’ of the connector body 40/collar 30. Also depicted is the rotating indexing tool 50, which will be explained in further detail with respect to FIG. 3.

(9) FIG. 1 depicts the cable assembly 10 prior to assembly and depicts the cable 22 in an orientation along a major longitudinal axis (e.g. the cable 22 and its longitudinal axis z, is oriented at 180 degrees with respect to the longitudinal axis x.sup.1 of the transition member 20 and x.sup.2 of the connector body 40, 42). In a preferred embodiment, the cable assembly 10 will be oriented with the cable 22 and its axis z, in a non-major longitudinal axis (e.g. not 90, 180, 270 or 360 degrees), when orienting the position of the transition member 20 with respect to the connector body 40, 42.

(10) FIG. 2 depicts the collar 30 having an outer diameter 31 of a cylindrical shape and an inner diameter 34 having a rectangular or triangular shape. In an embodiment, the connector body 40 has a triangular outer diameter and corresponds to the inner diameter 34 of the collar 30. In an embodiment the collar 30 is mechanically attached in between the connector body 40, 42 and the cable transition member 20. The collar 30 may be snap-fit onto the connector end face 37 (see FIG. 1). And, in such an embodiment, injection molding of the collar 30 via insert molding is not necessary.

(11) Turning to FIG. 3, an exploded view of the injection molding tool 60 is depicted prior to insertion of the cable 22, transition member 20, connector body 42 and rotating indexing tool 50 to the tool 60. In another embodiment, the injection molding of the collar 30 will be explained with respect to FIG. 3. (The depiction of the collar 30, upper cylinder 27, transition member 20 and boot 25 as shown in FIG. 3 is only for illustration purposes and in the actual injection molding process there would be no collar 30 as part of the connector body 42 (and only the cable 22) as the collar 30, cylinder 29 and boot 25 must be insert molded via the mold 60).

(12) The mold 60 includes first, second, third, fourth mold cavity segments 61, 62, 63, 64. The first mold cavity segment 61 receives the connector body 42 and rotating indexing tool 50. As shown in FIG. 3, cavity 61 does not have an injection tube and no molten polymer is injected into cavity 61. Cavity 61 is a non-active cavity for receiving the connector body 42 (which was previously injection molded at a different factory or in a different manufacturing step) and indexing tool 50.

(13) The rotating indexing tool 50 includes a first half 52 which is rotatable with respect to second half 54. Indicia, such as degree markings are provided on the outer diameter of the second half 54. For example, numerals 55 that are aligned with the arrow indicia 58. In FIG. 3, the indexing tool is oriented to position the cable body 42 at “180” degrees as it is the indicia aligned with arrow 58. 180 degrees (indicia 58) is the angular orientation of the cable 22 and its axis z (FIG. 1), with respect to axis x.sup.1 and x.sup.2 as depicted in FIG. 3. Once the rotating indexing tool 50 is rotated and indexed to the desired position (other than 90, 180, 270 or 360 degrees), so that the connector body 42 is oriented with respect to the cable 22 in the desired orientation on a non-major longitudinal axis; a fastener 57 is secured to lock the first half 52 to the second half 54 of the rotating indexing tool 50. For example, an Allen wrench may be inserted in the hex nut receptacle 57, so that the first half 52 may be fastened to the second half 54. (Reference to the cable assembly at a “right angle” is with respect to the bend 27 being at a 90 degree bend of the boot 25 with respect to cylinder 29, which is fixed with respect to the cable 22. The variable angular orientation of axis z, on the other hand, is with respect to axis x.sup.1/x.sup.2.)

(14) The rotating indexing tool 50 includes an inner diameter cavity 59 (see FIG. 1) that receives the connector body 42. The connector body 42 in a preferred embodiment has a triangular shaped outer diameter and the corresponding cavity (inner diameter) of the rotating indexing tool 50 second half 54 is also triangular shaped 59. Thus it is understood when rotating the second half 54 of the rotating indexing tool 50, that the connector body 42 will rotate in conjunction with the rotation of the second half 54 of the rotating indexing tool 50. The indexing tool 50 and connector body 42 (following insertion within the cavity 59 of the rotating indexing tool 50) are both inserted simultaneously within the first cavity 61.

(15) In a first embodiment, a bare cable 22 is inserted into fourth mold segment 64 and the rest of the transition member 20 (cylinder 29 and boot 25) is injection molded thereon. In a second embodiment, the cable 22 is prepared separately and the transition member 20 is pre-assembled. In the second embodiment, the upper cylindrical body 29 is inserted within the second mold cavity segment 62, the boot 25 is inserted within the third mold cavity segment 63 and the cable 22 is laid within the fourth mold cavity segment 64 and extends out of the cavity therefrom. The cable assembly 20 is fixed in position with respect to the connector body 10, so that first axis x.sup.1 is aligned with the longitudinal axis x.sup.2 of the cylinder 29. The alignment of the connector body 42 also aligns the latch lever 45 or key-way, so that it will not interfere with the attachment of the connector 10 (following the injection molding steps) when the connector is attached to a host. The front face 71 of the cylinder 29 abuts against the face 34/37 (FIG. 1) of the connector body 42 and this is the location where the insert molding of the collar 30 occurs.

(16) Injection tube 68 of the mold 60 receives molten plastic that is insert molded around the connector body 42 and adheres against the face 71 of the cylinder 29 of the transition member 20. Such insert molding fixes the cable 22 and transition member 20 to the connector body 42 and fixes the orientation of the connector body 42 with respect to the cylinder 29. It is understood that the mold half 60 depicted in FIG. 3 is enclosed with a second mold half (that is a mirror image of the first half) in order to complete the insert molding step. Following the insert molding, the mold half 60 is separated from the second mold half (not shown) so that the completed cable assembly 10 may be removed from the mold. The connector body 42 is then removed from the rotating indexing tool 50 and the connector body front end 15 may then be connected to a host receptacle in the field. The completed assembly 10 is depicted in FIG. 4, showing the connector body attached to the cable transition member 20 and the front end 15 of the cable assembly 10 ready to be mated with a host receptacle. The collar 30 is shown in its fixed position between the connector body 10 and the cable transition member 20.

(17) The invention includes the following steps:

(18) a. Provide a standard non-circular connector body 42 (may be a 3.sup.rd party manufactured connector) and cable transition member 20 mateable to a host receptacle;

(19) b. Select a predetermined orientation of the assembly with respect to the host receptacle between 1 and 360 degrees using indexing tool 50 (so that the cable extending at a right angle does not interfere with components extending from the host receptacle):

(20) c. Take the connector body 42 for supplemental operation separate from the cable 20;

(21) d. Attach a collar 30 between the cable transition member 20 and the connector body 42 either by insert molding (FIG. 3) or mechanically placing the collar 30 onto the connector body 42 adjacent the cable transition member 20 at the predetermined orientation by rotating the connector body 42 with respect to the cable assembly 20 (e.g., using an indexing tool;
e. Securing the connector body 42 in place in its predetermined orientation with respect to the cable 22 by fastening the collar 30 in non-movable position between the connector body 42 and cable transition member 20 (either by insert molding or mechanical means (e.g. snap-fit)); and securing the collar 30 in a manner that it does not interfere with the mating mechanism of the connector (e.g. a latch lever or 45 key-way of the connector); and
f. Attaching the assembly to the host receptacle in the predetermined orientation so that the right angle 27 cable 22 does not interfere with any components extending from the host receptacle. In another embodiment the right angle bend 27 could be replaced with any angle between 91 degrees and 179 degrees relative to x.sup.1.

Modifications and variations will be apparent to those skilled in the art and the scope of the invention is defined solely by the following claims and their equivalents.
