For optimum service life, wiring (e.g., coaxial, fiber optic, or other types) should be installed according to manufacturer's design specifications. However, during manufacture, transportation, or installation, wires may be prone to damage, misalignment, and creep (or elongation). The wires may also deviate from a specified bend radius or curvature, and accordingly have improper fitment. Further, when the wires are not properly configured to specifications, installation of the wires in tight spaces may be problematic and may damage the wires. When confronted with such problems, the operator typically interrupts the installation process to undertake time-consuming and costly wire repositioning and/or repairs.
Accordingly, apparatuses and methods, intended to address at least the above-identified concerns, would find utility.
The following is a non-exhaustive list of examples, which may or may not be claimed, of the subject matter according to the present disclosure.
One example of the present disclosure relates to a guide for a wire harness. The guide comprises a first surface and a second surface, at least a second portion of which is parallel to at least a first portion of the first surface. The guide also comprises a contoured surface between the first surface and the second surface as well as a plurality of through, circumferentially enclosed openings, extending from the first surface to the second surface. The contoured surface has a non-linear central axis parallel to at least the first portion of the first surface and to at least the second portion of the second surface. The contoured surface also has a concave cross-section.
Another example of the present disclosure relates to a system comprising a guide and a wire harness. The guide comprises a first surface and a second surface, at least a second portion of which is parallel to at least a first portion of the first surface. The guide also comprises a contoured surface between the first surface and the second surface as well as a plurality of through, circumferentially enclosed openings extending from the first surface to the second surface. The contoured surface has a non-linear central axis parallel to at least the first portion of the first surface and to at least the second portion of the second surface. The contoured surface also has a concave cross-section. The wire harness comprises wires that are routed along the contoured surface of the guide.
Yet another example of the present disclosure relates to a method of forming a wire harness. The method comprises coupling a guide to a form board such that a non-linear central axis of a contoured surface of the guide is parallel to the form board and the guide is not rotatable relative to the form board and routing wires along the contoured surface of the guide to form a bend in the wires.
Having thus described examples of the present disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein like reference characters designate the same or similar parts throughout the several views, and wherein:

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.
Illustrative, non-exhaustive examples, which may or may not be claimed, of the subject matter according the present disclosure are provided below.
In one or more examples of the present disclosure, which may or may not be claimed, guide 100, system 1000, and method 2000 promote low cost, efficient, and correct manufacturing, transportation, and installation of wires. With better fitment, fewer repairs are necessary, less time is required for adjustment of wires, and less wire creep (or wire elongation) occurs, enabling an operator to save both time and money. Also, guide 100, system 1000, and method 2000 increase a likelihood of wires maintaining desired wire bends. Further, guide 100, system 1000, and method 2000 utilize low cost and lightweight materials. A manufacturer, thus, may save on the costs related to weight instead of requiring numerous brackets to maintain a certain bend radius. Moreover, additional savings may be realized by less waste produced.
Referring generally to
Contoured surface 140 provides frame support upon which wires 310 of wire harness 610 may be positioned such that a particular desired bend (i.e., bend radius or curvature of wires 310) is maintained during manufacturing, transportation, and installation of wires 310 (or wires 310 and guide 100). Contoured surface 140 resists lateral displacement of wires 310 (e.g., from one side of guide 100 that is closer to first surface 120 to another side of guide 100 that is closer to second surface 130).
Parallel first and second portions 122, 132 of first and second surfaces 120, 130 provide planar alignment of guide 100 with a flat surface, such as that of form board 510. Such planar alignment is important for aligning the wires 310 when multiple guides 100 are coupled to form board 510, or other structure, to route wires 310.
Plurality of through, circumferentially enclosed openings 170 provides different arrangements to secure wires to guide 100 and/or to secure guide 100 to a flat surface, such as that of form board 510.
Advantageously, guide 100 enables manufacturing, transportation, and/or installation of the wires, or wires and guide 100, to be achieved according to design parameters and specifications.
As mentioned herein, the term “parallel”, as applied to lines and/or surfaces, shall be defined as lines and/or surfaces progressing so that the interval between them remains the same, within an applicable manufacturing tolerance. For example, second portion 132 being parallel to first portion 122 means that second portion 132 and first portion 122 are included in respective geometric planes that are parallel in space, within an applicable manufacturing tolerance. Furthermore, in one or more examples of the present disclosure, the bend formed by wires 310 may be curved, e.g., circular or compound or segmented.
Non-linear central axis 141 is coincident to at least first portion 122 of first surface 120 and to at least second portion 132 of second surface 130 and follows the bend or curvature in which wires 310 of wire harness 610 are positioned.
As used herein, a “central axis” of an object, such as a non-planar surface or a surface having circumferentially closed cross-sections, is a line, which may or may not be straight, passing through the centroid of each cross-section of the object that is perpendicular to the medial skeleton of the object. A medial skeleton of an object is a set of points not on the object's boundary such that at least two points on the object's boundary are equidistant from and closest to each point of the set of points. The centroid (geometric center) of a two-dimensional region, such as a cross-section of an object, is the “average” position of all the points in the two-dimensional region. As used herein, “non-linear” is defined as not denoting, involving, or arranged in a straight line and incorporates any non-straight line or non-straight portion of a line. For instance, non-linear central axis 141, in one or more examples, can include any angle that is not 180 degrees (e.g., a relatively sharp bend of 90 degrees).
Referring generally to
Providing inflection point 145 on non-linear central axis 141 of contoured surface 140 enables guide 100 to impart a complex curvature to wires 310 positioned on contoured surface 140.
For purposes of this disclosure, an “inflection point” is defined as a transition point between a concave portion and a convex portion, a concave portion and a straight portion, or a convex portion and a straight portion of a line.
Referring generally to
The curvature of non-linear central axis 141 of contoured surface 140 enables a local bend to be imparted to wires 310. In some implementations, multiple guides 100 can be used to route wires 310 in various directions within a designated area.
Referring generally to
For purposes of this disclosure, non-linear central axis 141 forms a “closed shape” when a configuration of a bend in wires 310 forming wire harness 610 is greater than 180 degrees (e.g., a complete circle, as an illustrative non-limiting example).
A closed shape of non-linear central axis 141 facilitates the bend in wires 310 along the circumference of guide 100 when the required bend of wires 310 is greater than 180 degrees, according to one or more examples of the present disclosure. In some examples, a closed shape of non-linear central axis 141 enables a closer fit of wires 310 around contoured surface 140 of guide 100. In some implementations, the closed shape of non-linear central axis 141 allows wires 310 to fully wrap around guide 100 in formation of wire harness 610.
Referring generally to
For purposes of this disclosure, non-linear central axis 141 forms an “open shape” when a configuration of a bend in wires 310 forming wire harness 610 is less than or equal to 180 degrees (e.g., a semicircle, as an illustrative non-limiting example).
An open shape of non-linear central axis 141 of contoured surface 140 facilitates the bend in wires 310 along the circumference of guide 100 when the bend in wires 310 is less than or equal to 180 degrees, according to one or more examples of the present disclosure. In some examples, the open shape may enable guide 100 to be of smaller size and less weight than a guide having a closed shape, providing conservation of space and weight e.g., when wire harness 610 is transported together with at least one guide 100.
In particular examples, wire harness 610 may be formed using guides 100 having only open shapes, guides 100 having only closed shapes, or a combination thereof, depending on design requirements and space constraints associated with forming, transporting, and/or installing wires 310, wire harness 610, or both.
Referring generally to
At least one first opening 180 and two or more second openings 190 provide different arrangements to secure wires 310 to guide 100 and/or to secure guide 100 to various structures or support surfaces (e.g., form board 510). In one or more examples of the present disclosure, at least one first opening 180 is at least one slot configured to accommodate at least one strap 410 (e.g., band, belt, leash, cable tie, etc.) to secure wires 310, or wire harness 610, to guide 100. Once wires 310 are secured to guide 100 in the aforementioned manner, a desired wire curvature is maintained and less wire creep relative to guide 100 is observed.
Referring generally to
At least one first opening 180 having an elongated shape enables straps 410 to remain taut, firm, and/or flat within at least one first opening 180. When straps 410 are taut, firm, and/or flat, curvature of wires 310 relative to guide 100 is maintained and less wire creep with respect to guide 100 is observed.
As used herein, “elongated shape” shall mean any shape conducive to accommodating any type of strap, band, belt, and/or leash that may be rectangular or may have rounded ends, e.g., a milled slot.
Referring generally to
In one or more examples, two or more second openings 190 having circular cross-sectional shape are peg holes configured to accommodate pegs 290 to anchor guide 100 to form board 510, for example, or to another similar structure. In other examples, two or more second openings 190 may be used to affix guide 100 to various structures for proper installation of wires 310.
Referring generally to
At least one first opening 180 being parallel to a line tangent to non-linear central axis 141 (e.g., a straight slot) enables optimal positioning of straps 410 relative to guide 100 for securing wires 310. At least one first opening 180 being parallel to a line tangent to non-linear central axis 141 further promotes a tighter binding of wires 310 to guide 100.
An illustrative non-limiting example of at least one first opening 180 being parallel to a line tangent to non-linear central axis 141 is shown in
In some examples, as shown in
Referring generally to
When used with multiple straps 410 (e.g. cable ties), for example, at least one first opening 180 being parallel to non-linear central axis 141 (e.g., a curved slot) enables a greater conformance of straps 410 to the bend of wires 310 and curvature of guide 100, to promote better conformance of wires 310 to the curvature of guide 100.
An illustrative non-limiting example of at least one first opening 180 being parallel to non-linear central axis 141 is shown in
Referring generally to
At least a portion of at least one first opening 180 being closer to non-linear central axis 141 than at least a portion of any one of two or more second openings 190 promotes proper securing of wires 310 to guide 100, decreases the possibility of interference of the pegs of form board 510 in the formation and positioning of wire harness 610, and promotes the intended exact placement of wires 310. At least a portion of at least one first opening 180 being closer to non-linear central axis 141 than at least a portion of any of two or more second openings 190 also enables use of a shorter strap 410 to secure wires 310 to guide 100.
Referring generally to
All portions of at least one first opening 180 being closer to non-linear central axis 141 than all portions of any one of two or more second openings 190 promotes proper securing of wires 310 to guide 100, prevents interference of the pegs of form board 510 in the formation and positioning of wire harness 610, and promotes the intended exact placement of wires 310. All portions of at least one first opening 180 being closer to non-linear central axis 141 than all portions of any one of two or more second openings 190 also enables use of a shorter strap 410 to secure wires 310 to guide 100 and prevents interference between strap 410 and at least one peg 290 during formation of wire harness 610.
Referring generally to
One of two or more first openings 180 being proximate first end 210 of contoured surface 140 and another of two or more first openings 180 being proximate second end 220 of contoured surface 140 promotes proper conformance of wires 310 to guide 100 and facilitates the intended routing of wires 310. A desired wire curvature may be maintained and less wire creep relative to guide 100 may be observed.
Referring generally to
Two or more first openings 180 being parallel to a line tangent to non-linear central axis 141 (e.g., straight slots) enable positioning of straps 410 relative to guide 100 such that straps 410 can tightly secure wires 310 without excessive deformation of the straps. Furthermore, at least one first opening 180 being parallel to a line tangent to non-linear central axis 141 enables the use of straps 410 each approaching the width of first opening 180 to deliver a larger gripping surface.
Referring generally to
Two or more first openings 180 parallel to non-linear central axis 141 (e.g., curved slots) are well suited for use with straps 410 that are thin (e.g. cable ties) to enable a greater conformance of the straps to the wire bend and to promote tighter wrapping of wires 310 around the curves of guide 100, especially when two or more straps are used in conjunction with each first opening 180.
Referring generally to
At least one peg 290 extending from at least one of first surface 120 or second surface 130 provides the capability to secure guide 100 to form board 510 or other structures during manufacturing, transportation, and/or installation of the wire harness. At least one peg 290, extending from at least one of first surface 120 or second surface 130, enables the use of form board 510 having only openings to receive two or more pegs 290 or openings to receive peg 290 and pegs to be received within openings 190 of the guide 100.
Referring generally to
At least one peg 290 being configured to be inserted into one of two or more second openings 190 provides the capacity to adjoin guide 100 to form board 510 or other structure with varying levels of mobility of guide 100 relative to the form board 510 such that in some instances, guide 100 may be able to at least temporarily rotate relative to form board 510 or other structure during manufacturing, transportation, and/or installation of the harness.
Referring generally to
At least one peg 290 being configured to be inserted into one of two or more second openings 190 with a clearance fit provides the capability of at least one peg 290 to rotate or slide freely within two or more second openings 190. For example, at least one peg 290 can be inserted into one of two or more second openings 190 to anchor guide 100 to form board 510 and can be removed from one of two or more second openings 190 to decouple guide 100 from form board 510 without the use of tools.
Referring generally to
At least one discontinuity 150 formed in first surface 120, second surface 130, and contoured surface 140 enables wires 310 to be secured to the guide 100 using various shapes and sizes of bundle ties 320 (i.e., connectors, fasteners, cable ties etc.) after wires 310 are conformed to the guide 100, with minimal or no strain of wires 310.
At least discontinuity 150 may take any shape that enables accommodation of bundle ties 320. For example, at least discontinuity 150 may include one or more notches, grooves, notches joined by smaller grooves, etc.
Referring generally to
Each discontinuity 150, having central axis 151 substantially perpendicular to first portion 122 of first surface 120, to second portion 132 of second surface 130, and to non-linear central axis 141 of contoured surface 140, promotes orientation of bundle ties 320 relative to wires 310 intended to insure that the bundle ties 320 positively grip wires 310 without slipping. In other words, creep of the bundle ties 320 relative to the wires is reduced, promoting the integrity of the assembly of wires 310.
Referring generally to
Groove 160 that fully interrupts contoured surface 140 enables installation of bundle ties 320 after conforming wires 310 to guide 100 such that the desired bend of wires 310 around contoured surface 140 is maintained and without straining wires 310.
Referring generally to
Three or more discontinuities 150 spaced at intervals X along contoured surface 140 enable installation of a specified number of bundle ties 320 around wires 310 without excessively straining wires 310 so that the wires are held securely together and the desired bend of wires 310 around contoured surface 140 of guide 100 is maintained. Additionally, wire creep is reduced and wires 310 are better protected from wear and tear.
Referring generally to
Intervals X being identical to each other provides proper positioning and balanced support to bundle ties 320, wires 310, and guide 100, so that strain is reduced and desired wire bend is maintained. Referring, e.g., to
Referring generally to
First notch 162 and second notch 164 partially interrupting contoured surface 140 enable installation of bundle ties 320 after conforming wires 310 to guide 100 such that the desired bend of wires 310 around contoured surface 140 of guide 100 is maintained and without excessively straining wires 310.
Referring generally to
Groove 160 fully interrupting first notch 162, second notch 164, and contoured surface 140 protects bundle ties 320, wires 310, and guide 100 by reducing strain of the wires and promoting a desired bend of wires 310. Referring, e.g., to
Referring generally to
Use of a polymeric material to form guide 100 decreases weight and the associated cost of manufacturing of the guide. Furthermore, the transportation cost of wire harness 610 is reduced and ease of installation increased.
Polymeric materials may include, but are not limited to, various plastics, individually or in combination, such as polyurethanes, polyesters, epoxy resins, phenolic resins, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, or polytetrafluoroethylene. It is noted that in some examples guide 100 may be made of polymeric material(s) in addition to other (e.g., non-polymeric) materials.
Referring generally to
Contoured surface 140 provides frame support upon which wires 310 of wire harness 610 may be positioned such that a particular desired harness configuration (i.e., bend radius or curvature of wires 310) is maintained during manufacturing, transportation, and installation of wires 310 (or system 1000). Contoured surface 140 resists lateral displacement of wires 310 (e.g., from one side of guide 100 that is closer to first surface 120 to another side of guide 100 that is closer to second surface 130).
Parallel first and second portions 122, 132 of first and second surfaces 120, 130 provide planar alignment of guide 100 with a flat surface, such as that of form board 510. Such planar alignment is important for aligning wires 310 when multiple guides 100 are coupled to form board 510, or another structure, to route wires 310. Advantageously, correct manufacturing, transportation, and/or installation of system 1000 is achieved according to design parameters and specifications.
Non-linear central axis 141 is coincident to at least first portion 122 of first surface 120 and to at least second portion 132 of second surface 130 and follows the bend or curvature in which wires 310 of wire harness 610 are positioned.
Plurality of through, circumferentially enclosed openings 170 provides different arrangements to secure wires 310 to guide 100 and/or to secure guide 100 to a flat surface, such as that of form board 510.
Referring generally to
At least one discontinuity 150 formed in first surface 120, second surface 130, and contoured surface 140 enables wires 310 to be secured to the guide 100 using various shapes and sizes of bundle ties 320 (i.e., connectors, fasteners, cable ties etc.) after wires 310 are conformed to the guide 100, with minimal or no strain of wires 310.
Referring generally to
At least one bundle tie 320 being configured to pass through one of discontinuities 150 underneath wires 310 of wire harness 610 to secure wires 310 of wire harness 610 together enables wires 310 to be securely fastened so a desired wire bend is maintained.
Referring generally to
At least one strap 410 passing through at least one through, circumferentially enclosed opening 170 to secure wire harness 610 to guide 100 enables wires 310 to be securely fastened to system 1000, maintain desired wire bend, and promote reduced wire creep.
In one or more examples, at least one strap 410 may be made of any material or fabric used in manufacturing, transportation, and/or installation of bend radius wire harness guides.
Referring generally to
Non-linear central axis 141 being parallel to form board 510 prevents interference of form board 510 in the formation and positioning of wire harness 610 and promotes the intended exact placement of wires 310 per customized specifications. Restricting guide 100 from rotating relative to form board 510 allows guide 100 to be affixed such that the placement of wires 310 and wire harness 610 is maintained according to design specifications.
As used herein, guide 100 being “not rotatable” relative to form board 510 means that guide 100 is restricted from rotation relative to form board 510 within manufacturing tolerance. It is to be understood that excessive amounts of force, such as amounts outside of manufacturing tolerance, may nonetheless result in guide 100 rotating relative to form board 510.
Referring generally to
Use of at least two pegs 290 to couple guide 100 to form board 510 provides proper alignment and positioning of guide 100 and wires 310 relative to form board 510 during manufacturing, transportation, and/or installation.
Referring generally to
Routing and securing bundle tie(s) 320 provides proper alignment, positioning, and support of wires 310 of wire harness 610 during manufacturing, transportation, and/or installation.
Referring generally to
Utilizing straps 410 to secure wire harness 610 to guide 100 provides proper alignment, positioning, and support for wire harness 610 during manufacturing, transportation, and/or installation. Decoupling wire harness 610 and guide 100 from form board 510, once wire harness 610 and guide 100 are secure, enables transportation of wire harness 610, guide 100, and wires 310, and enables use of form board 510 to be used in forming another wire harness 610.
Each of the processes of illustrative method 2000 may be performed or carried out by a system integrator, a third party, and/or an operator (e.g., a customer). For the purposes of this description, a system integrator may include, without limitation, any number of manufacturers and major-system subcontractors; a third party may include, without limitation, any number of vendors, subcontractors, and suppliers; and an operator may be an leasing company, military entity, service organization, and so on. Thus, in some examples, processes of illustrative method 2000 may be automated by manufacturing equipment or machinery.
