## Background
BACKGROUND
1. Field
The exemplary embodiments generally relate to backshells and in particular to split backshells for wire bundles.
2. Brief Description of Related Developments
Wire bundle forming for, e.g., an aircraft uses a manual approach increasing labor and cost for the production of the aircraft. The process of wire forming involves laying out connectors on a formboard and routing wires to their appropriate location (second end) on the formboard. As the wires are routed to the second end location, they are routed through backshells prior to insertion into an electrical connector.
Backshells provide a transition between a wire bundle and an electrical connector. The backshells provide benefits such as strain relief and ground paths for the wires. Strain relief backshells in particular provide a clamping force on the wire bundle to prevent damage to the wires of the wire bundle.
Generally, backshells comprise a solid cylindrical/tubular piece and are laid out prior to wiring to ensure the wire bundle is passed through the backshell. If a backshell is missed or not in place, the wires must be re-run.

DETAILED DESCRIPTION
The embodiments described herein may provide an improved backshell 100, 100′ which may be installed around a wire or a wire bundle after routing of the wire(s) to, and connection with, a wire connector. Illustrative, non-exhaustive examples, which may or may not be claimed, of the subject matter according to the present disclosure are provided below.
Referring to FIGS. 1 and 2, the aspects of the present disclosure described herein disclose a backshell 100 configured to secure and support a wire bundle, and including, for example, strain relief and grounding properties.
In one aspect, the backshell 100 described herein is described with respect to use in an aircraft 1400 electrical system 1402, illustrated in FIG. 15; while in other aspects, the backshell 100 may be applied to other industries, including, but not limited to, automotive industries, maritime industries, and aerospace industries.
In one aspect, the backshell 100 generally includes a first shell member 101 having a first end 101a, a second end 101b, and a first channel 101c extending between the first end 101a and the second end 101b; a second shell member 102 having a first end 102a, a second end 102b, and a second channel 102c extending between the first end 102a and the second end 102b; and a coupling ring 103. In one aspect, the backshell 100 also includes at least one protrusion 101p, 102p and at least one clamp member 201, 202 as will be further described herein.
The first and second shell members 101, 102 and the coupling ring 103 are generally formed from the same material, for example, one or more of a plastic, composite, or metal and formed in any suitable manner such as additive manufacturing, extrusion, molding, machining, etc. In other aspects, the first and second shell members 101, 102 and the coupling ring 103 may be formed from different materials and in any suitable manner. In one aspect, the material forming the backshell 100 provides electromagnetic interference shielding/protection for a wire(s) or wire bundle. In one aspect, the material forming the backshell may be a composite having shielding properties. In one aspect, the electromagnetic interference shielding/protection of the backshell 100 may be a coating deposited on the backshell 100. In one aspect, the electromagnetic interference shielding/protection may include a foam, rubber, and/or resilient block disposed within or around the backshell 100.
In one aspect, the first and second shell members 101, 102 interface so as to form the backshell 100. In one aspect, the first and second shell members 101, 102 interface at parting line 105 formed by edges 101ED, 102ED of the first and second shell members 101, 102 respectively. In one aspect, with the edges 101ED, 102ED of the first and second shell members 101, 102 interfaced at parting line 105, the first end 101a of the first shell member 101 and the first end 102a of the second shell member 102 are adjacent one another defining a backshell first end 100a, while the second end 101b of the first shell member 101 and the second end 102b of the second shell member 102 are adjacent one another defining a backshell second end 100b. In one aspect, parting line 105 extends between the backshell first end 100a and the backshell second end 100b along a longitudinal plane LP of the backshell 100; while in other aspects, the parting line 105 may be defined by the first shell member 101 and the second shell member 102 in any suitable manner such that the parting line 105 is not necessarily substantially straight. In one aspect, the first and second shell members 101, 102 include attachment features. In one aspect, the attachment features are apertures, through which any suitable fastener passes to couple the first shell member 101 and the second shell member 102. In one aspect, the attachment features are snap fasteners (i.e., a male portion on one member snapping into a female portion on the other member). In one aspect, the attachment features are any suitable fastener device/mechanism to couple the first shell member 101 to the second shell member 102.
Still referring to FIGS. 1 and 2, in one aspect, the first channel 101c extends from the first end 101a of the first shell member 101 to the second end 101b of the first shell member 101 and has a width CW1 and a depth CD1. In one aspect, the second channel 102c extends from the first end 102a of the second shell member 102 to the second end 102b of the second shell member 102 and has a width CW2 and a depth CD2. In one aspect, the first and second shell members 101, 102 interface, such that the first and second channels 101c, 102c form a wire bundle passage 104 extending between the backshell first end 100a and the backshell second end 100b. In one aspect, each width CW1, CW2 and depth CD1, CD2 corresponds to dimensions of a wire bundle. In other aspects, the widths CW1, CW2 and the depths CD1, CD2 are any suitable width or depth such that one or more wires may pass through the wire bundle passage 104. In one aspect, the widths CW1, CW2 and the depths CD1, CD2 are sized for a wire bundle such that dust and/or debris are substantially prevented from entering the backshell second end 100b. 
Referring now to FIGS. 1, 3 and 4a, in one aspect, the first shell member 101 includes a first coupling ring retaining flange portion 106a. In one aspect, the first coupling ring retaining flange portion 106a extends partially, for example, a distance X around a circumference 100C of the backshell first end 100a. In one aspect, the second shell member 102 includes a second coupling ring retaining flange portion 106b. In one aspect, the second coupling ring retaining flange portion 106b extends partially, for example, a distance Y around the circumference 100C of the backshell first end 100a. The first coupling ring retaining flange portion 106a and the second coupling ring retaining flange portion 106b form coupling ring retaining flange 106 when the first and second shell members 101, 102 are interfaced with one another.
In one aspect, the coupling ring retaining flange 106 extends radially outward with respect to a centerline CL1 of the wire bundle passage 104, as seen in FIG. 4a. In one aspect, the coupling ring retaining flange 106 includes at least one protrusion 109 extending from the coupling ring retaining flange 106. In one aspect, the at least one protrusion 109 engages a wire bundle connector 500, for example mating protrusions 509 of the wire bundle connector 500, seen in FIG. 5 and further described below. The at least one protrusion 109 engaging the wire bundle connector 500 prevents the backshell 100 from rotating relative to the wire bundle connector 500 (i.e., the at least one protrusion 109 provides anti-rotation of the backshell 100 relative to the wire bundle connector 500) when, e.g., the coupling ring 103 is fastened to the wire bundle connector 500.
In one aspect, the first coupling ring retaining flange portion 106a and the second coupling ring retaining flange portion 106b, extending only partially around the circumference 100C of the back shell first end 100a, forms one or more gaps 106g between the ends 106ae of the first coupling ring retaining flange portion 106a and the ends 106be of the second coupling ring retaining flange portion 106b. In one aspect, the gap(s) 106g are located adjacent the parting line 105. In one aspect, the gap(s) 106g are sized such that, the first shell member 101 and the second shell member 102 may be angled relative to each other about the parting line 105 for engaging the coupling ring 103 (see FIG. 11) as will be further described below. For example, when angled, the effective circumference or outer diameter D1′ (FIG. 11) of the coupling ring retaining flange 106 is smaller than an inner diameter D2 of a backshell retaining flange 107 of the coupling ring 103 to allow passage of the coupling ring retaining flange 106 through the backshell retaining flange 107, as will be described below; but when the first shell member 101 and the second shell member 102 are mated at parting line 105, an interference fit 100IF (i.e., a fit in which there is interference for all tolerance conditions) is formed with the coupling ring 103, such that the circumference or outer diameter D1 (FIG. 4a) of the coupling ring retaining flange 106 is larger than the inner diameter D2 of the backshell retaining flange 107 so that the coupling ring 103 is retained on the first and second shell members 101, 102 through the interference fit 100IF between the coupling ring retaining flange 106 and the backshell retaining flange 107 (the coupling ring retaining flange 106 interfaces with and retains/prevents removal of the backshell retaining flange 107).
In one aspect, the coupling ring retaining flange 106 includes a recess 106R in which the backshell retaining flange 107 is disposed to retain the coupling ring 103 on the first and second shell members 101, 102. The recess 106R retains the backshell retaining flange 107 between a stop surface 106S of the coupling ring retaining flange 106 and a seating surface 101X, 102X of the first and second shell members 101, 102. The recess circumference is substantially similar to the inner diameter D2 of the backshell retaining flange 107 however, maintaining enough clearance between them so that the coupling ring 103 may rotate relative to the first ends 101a, 102a of the first and second shell members 101, 102 when the first and second shell members 101, 102 are interfaced at the parting line 105. The clearance between the backshell retaining flange 107 and the recess 106R may be such that the first and second shell members 101, 102 are held in substantial contact by the backshell retaining flange 107 of the coupling ring 103 when the first and second shell members 101, 102 are interfaced at the parting line 105. In one aspect, the coupling ring 103 rotates relative to the backshell first end 100a in direction 103D.
Referring again to FIGS. 1 and 2, in one aspect, as noted above, the first and second shell members 101, 102 include the at least one protrusion 101P, 102P. In one aspect, protrusions 101P, 102P are in a fixed spatial relationship with and extend a distance XP from a respective second end 101b, 102b of each of the first and second shell members 101, 102. In one aspect, protrusions 101P, 102P are provided to interface with the at least one clamp member 201, 202 as will be further described herein, to couple the first and second shell members 101, 102 to each other where the at least one clamp member 201, 202 and the coupling ring 103 in combination maintain the first and second shell members 101, 102 in substantial contact with each other at the parting line 105.
In one aspect, referring to FIGS. 6 and 7, protrusions 101P, 102P are coupled to each respective first and second shell members 101, 102 by an articulated joint 100AJ, such that protrusions 101P, 102P may rotate relative to the first and second shell members 101, 102 to provide an adjustable routing for the wire(s) of the wire bundle through the backshell 100. In one aspect, protrusions 101P, 102P are rotatable in directions PA1, PA2 about pivot point PP. In one aspect, the articulated joint 100AJ includes one or more anti-rotation members 101S, 102S, such that protrusions 101P, 102P may be locked (e.g., prevent further rotation) into place at any desired angle preventing further rotation about the pivot point PP. For example, protrusions 101P, 102P may be locked into place so that protrusions 101P, 102P are extended in-line with or at about 0 degrees (which may be coincident with the centerline CL1) to the first end(s) 101a, 102a of the first and/or second shell members 101, 102; while in other aspects, protrusions 101P, 102P may be positioned and locked at least about 90 degrees in either direction PA1 or PA2 relative to the first end(s) 101a, 102a of the first and/or second shell members 101, 102 or at any position between +90 degrees and −90 degrees. In still other aspects, protrusions 101P, 102P may be rotatable more than +90 degrees and/or −90 degrees. In one aspect, the one or more anti-rotation members 101S, 102S are self-locking screws. In one aspect, the one or more anti-rotation members 101S, 102S are any suitable anti-rotation mechanism including friction members, toothed members, pins, etc. In one aspect, the backshell 100 includes at least one recess 100I so that with protrusions 101P, 102P rotated about the pivot point PP, the wire(s) or wire bundle may be inserted into the recess 100I to provide a stress free/gradual bend to the wire(s).
Referring now to FIGS. 1, 2, 4b and 5, in one aspect, the at least one clamp member 201, 202 includes two opposing clamp members. In one aspect, the at least one clamp member 201, 202 includes one or more fasteners 203, 204. In one aspect, the one or more fasteners 203, 204 are nuts and bolts, screws, pins or any other suitable fastener(s). In one aspect, the at least one clamp member 201, 202 engages the first and second shell members 101, 102 to couple the first and second shell members 101, 102 to each other. In one aspect, the at least one clamp member 201, 202 engages the first and second shell members 101, 102 at protrusions 101P, 102P. In one aspect, the at least one clamp member 201, 202 includes two opposing clamp members that clamp/engage a wire(s) or wire bundle, passing through the wire bundle passage 104, relative to the backshell 100 to provide strain relief to the connection between the wire(s) and the wire bundle connector 500. In one aspect, the at least one clamp member 201, 202 spans the parting line 105 so that a clamping force of the at least one clamp member 201, 202 does not affect positioning of the first and second shell members 101, 102 relative to one another. In one aspect, a first engagement surface 101E and a second engagement surface 102E on protrusions 101P, 102P are spaced a distance S and engage surfaces 201E, 202E are also spaced a distance S on the at least one clamp member 201, 202, so that the first and second shell members 101, 102 are held together at the backshell second end 100b independent of the clamping force of the at least one clamp member 201, 202.
Referring now to FIGS. 1-3, in one aspect, the coupling ring 103 includes the backshell retaining flange 107 as noted above. In one aspect, the backshell retaining flange 107 extends radially inward relative to a centerline CL2 of the coupling ring 103. In one aspect, the coupling ring 103 engages both the first shell member 101 and the second shell member 102 to couple the first ends 101a, 102a of the first and second shell members 101, 102 to each other. In one aspect, the coupling ring 103 engages both the first and second shell members 101, 102 at the backshell first end 100a of the backshell 100. In one aspect, as described above, the backshell retaining flange 107 engages the coupling ring retaining flange 106 such that the coupling ring 103 is retained by the coupling ring retaining flange 106 of the first and second shell members 101, 102. In one aspect, the coupling ring 103 may engage the first and second shell member 101, 102 at any suitable location to couple the first and second shell members 101, 102 to each other.
In one aspect, the outer circumference or outer diameter D1 of the coupling ring retaining flange 106 is larger than the inner circumference or inner diameter D2 of the backshell retaining flange 107. The outer diameter D1 of the coupling ring retaining flange 106 is larger than the inner diameter D2 of the backshell retaining flange 107 so that the backshell retaining flange 107 is retained in the recess 106R when the first and second shell members 101, 102 are inserted into the coupling ring 103 so that seating surface 107s of the backshell retaining flange 107 engages the stop surface 106s of the coupling ring retaining flange 106.
In one aspect, the seating surface 107S interfaces with the stop surface 106S of the coupling ring retaining flange 106 to prevent the backshell retaining flange 107 from escaping the recess 106R and thus, preventing the coupling ring 103 from detaching from the first and second shell members 101, 102. In one aspect, with the backshell retaining flange 107 retained in the recess 106R, the coupling ring 103 may move longitudinally relative to the first and second shell members 101, 102; however, when the coupling ring 103 is tightened on the wire bundle connector 500 as will be further described below, longitudinal movement is prevented where the seating surface 107s pushes on the stop surface 106s so that the at least one protrusion 109 engage the mating protrusions 509 of the wire bundle connector 500 to prevent rotation of the backshell 100 relative to the wire bundle connector 500.
In one aspect, the coupling ring 103 includes a coupling feature 108 that engages a mating coupling feature 508 of the wire bundle connector 500. In one aspect, coupling feature 108 is a threaded coupling. In one aspect, coupling feature 108 is any suitable engagement mechanism to couple the coupling ring 103 and the retained first and second shell members 101, 102 to, for example, a wire bundle connector 500, as seen in FIG. 5. In one aspect, when the coupling ring 103 is engaged and tightened to the wire bundle connector 500, this engagement may maintain the first shell member 101 and the second shell member 102 in a predetermined relationship relative to each other to prevent the first and second shell member 101, 102 from being removed from the coupling ring 103. In one aspect, the mating protrusions 509 provide support in maintaining the first and second shell members 101, 102 in a predetermined relationship relative to each other, where compressive forces applied to the stop surface 106S by the coupling ring 103 compresses or otherwise holds the coupling ring retaining flange 106 against the wire bundle connector 500 so that the first and second shell members 101, 102 are in substantial contact along the parting line 105 and prevents the first and second shell members 101, 102 from separating and thus, being removed from the coupling ring 103. In one aspect, the coupling ring 103 is a single unitary one piece member but in other aspects, the coupling ring 103 may include more than one piece. For example, referring to FIG. 8, the coupling ring 103 includes a first member 1031 and a second member 1032. Generally, the first member 1031 and the second member 1032 interface at parting line 1035 to form the coupling ring 103. In one aspect, the interface between the first member 1031 and the second member 1032 includes at least one attachment feature 1036, 1037. In one aspect, the at least one attachment feature 1036, 1037 is an aperture, through which any suitable fastener passes to couple the first member 1031 and the second member 1032, or a snap (i.e., a male portion on one member snapping into a female portion on the other member). In one aspect, the at least one attachment feature 1036, 1037 is any suitable fastener device/mechanism to couple the first member 1031 to the second member 1032. In one aspect, each member 1031, 1032 includes threads 103T1, 103T2. In one aspect, the threads 103T1 of the first member 1031 align with the threads 103T2 of the second member 1032 so that when the coupling ring 103 is formed (e.g., the first member 1031 and the second member 1032 are coupled to each other), the threads 103T1, 1032T2 of each member 1031, 1032 form one continuous uninterrupted thread.
In one aspect, referring to FIG. 9, the coupling ring 103 further includes one or more ground wire/strap 900, where the one or more ground wire/strap 900 provides a ground path to electrically bond the first and second shell members 101, 102 to the coupling ring 103 and thus the wire bundle connector 500 as will be further described below with respect to the at least one clamp member 201, 202.

It will be understood that not all relationships among the various disclosed elements are necessarily represented. Accordingly, couplings other than those depicted in the drawings may also exist. Dashed lines, if any, connecting blocks designating the various elements and/or components represent couplings similar in function and purpose to those represented by solid lines; however, couplings represented by the dashed lines may either be selectively provided or may relate to alternative examples of the present disclosure. Likewise, elements and/or components, if any, represented with dashed lines, indicate alternative examples of the present disclosure. One or more elements shown in solid and/or dashed lines may be omitted from a particular example without departing from the scope of the present disclosure. Environmental elements, if any, are represented with dotted lines. Virtual (imaginary) elements may also be shown for clarity. Those skilled in the art will appreciate that some of the features illustrated in the figures, may be combined in various ways without the need to include other features described in the figures, other drawing figures, and/or the accompanying disclosure, even though such combination or combinations are not explicitly illustrated herein. Similarly, additional features not limited to the examples presented, may be combined with some or all of the features shown and described herein.
In FIGS. 12, 14 and 16, referred to above, the blocks may represent operations and/or portions thereof and lines connecting the various blocks do not imply any particular order or dependency of the operations or portions thereof. Blocks represented by dashed lines indicate alternative operations and/or portions thereof. Dashed lines, if any, connecting the various blocks represent alternative dependencies of the operations or portions thereof. It will be understood that not all dependencies among the various disclosed operations are necessarily represented. FIGS. 12, 14 and 16 and the accompanying disclosure describing the operations of the method(s) set forth herein should not be interpreted as necessarily determining a sequence in which the operations are to be performed. Rather, although one illustrative order is indicated, it is to be understood that the sequence of the operations may be modified when appropriate. Accordingly, certain operations may be performed in a different order or simultaneously. Additionally, those skilled in the art will appreciate that not all operations described need be performed.
In the following description, numerous specific details are set forth to provide a thorough understanding of the disclosed concepts, which may be practiced without some or all of these particulars. In other instances, details of known devices and/or processes have been omitted to avoid unnecessarily obscuring the disclosure. While some concepts will be described in conjunction with specific examples, it will be understood that these examples are not intended to be limiting.
Unless otherwise indicated, the terms “first,” “second,” etc. are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, e.g., a “second” item does not require or preclude the existence of, e.g., a “first” or lower-numbered item, and/or, e.g., a “third” or higher-numbered item.
Reference herein to “one example” means that one or more feature, structure, or characteristic described in connection with the example is included in at least one implementation. The phrase “one example” in various places in the specification may or may not be referring to the same example.
As used herein, a system, apparatus, structure, article, element, component, or hardware “configured to” perform a specified function is indeed capable of performing the specified function without any alteration, rather than merely having potential to perform the specified function after further modification. In other words, the system, apparatus, structure, article, element, component, or hardware “configured to” perform a specified function is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the specified function. As used herein, “configured to” denotes existing characteristics of a system, apparatus, structure, article, element, component, or hardware which enable the system, apparatus, structure, article, element, component, or hardware to perform the specified function without further modification. For purposes of this disclosure, a system, apparatus, structure, article, element, component, or hardware described as being “configured to” perform a particular function may additionally or alternatively be described as being “adapted to” and/or as being “operative to” perform that function.
Different examples of the apparatus(es) and method(s) disclosed herein include a variety of components, features, and functionalities. It should be understood that the various examples of the apparatus(es) and method(s) disclosed herein may include any of the components, features, and functionalities of any of the other examples of the apparatus(es) and method(s) disclosed herein in any combination, and all of such possibilities are intended to be within the scope of the present disclosure.
Many modifications of examples set forth herein will come to mind to one skilled in the art to which the present disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings.
Therefore, it is to be understood that the present disclosure is not to be limited to the specific examples illustrated and that modifications and other examples are intended to be included within the scope of the appended claims. Moreover, although the foregoing description and the associated drawings describe examples of the present disclosure in the context of certain illustrative combinations of elements and/or functions, it should be appreciated that different combinations of elements and/or functions may be provided by alternative implementations without departing from the scope of the appended claims. Accordingly, parenthetical reference numerals in the appended claims are presented for illustrative purposes only and are not intended to limit the scope of the claimed subject matter to the specific examples provided in the present disclosure.
