The present disclosure generally relates to tooling components and systems for cable harness or wire harness manufacturing.
Cable harness manufacturing is often a complex operation, which reflects the complexity of the cable harnesses currently in use, including for example in electric vehicles. The cables of the harness are for example wires, electrical cables, optical fibres or other cables, the harness will also typically include connectors connected by cables of the harness. An example of a known wiring harness production system is described for example in WO 2014/181060. The arrangement described therein provides an assembly board having attachment surface for receiving cable routing elements and for routing cables in proximity to the attachment surface.
As cable harness manufacturing becomes ever more complex, there is a need for a system that can accommodate the greater size and complexity of components and cables required for cable harness manufacture while providing for sufficient user access to all portions of the cable harness. Therefore, there is a need to provide improved tooling components and improved cable harness manufacturing system that are adjustable and extendable to take account of the increasing variety, size requirements, and complexity of cable harnesses and allows flexibility in the location of cable fixing elements to support manufacture of different cable types.
According to embodiments of a first aspect, there is provided a routing element for use in a cable harness manufacturing system which includes an assembly board having an attachment surface configured for receiving tooling components to support and locate a cable harness during manufacture. The routing element includes an upper fixture support having at least one aperture for receiving a tooling component to support the cable harness during manufacture and a lower suction holder including at least two suction cups for attaching the routing element to the assembly board. The lower suction holder and the upper fixture support are located axially about a central vertical axis of the routing element. The lower suction holder extends outwardly relative to the upper fixture support, such that the area covered by the lower suction holder is greater than that of the upper fixture support. The arrangement advantageously provides for secure attachment of the routing element at the assembly board. Further, it provides high levels of stability for the tooling components and the supported cable harness. Routing elements according to the specification have an increased surface contact area at the assembly board due to the multiple suction cups. The use of multiple suction cups provides an increased suction force. The suction cups work in combination to provide secure attachment. The combination of features of the routing elements facilitates use at an assembly board arranged at an angle to the horizontal. A footprint of the upper fixture support portion is less than that of the lower suction holder portion which provides stability at the support as the loads are supported centrally of the lower suction holder of the routing element to the board.

The support plates 600 of
Referring to the arrangement of
The support plates 600 may be formed of a metal material, for example Aluminum. Alternatively, support plate 600 may be formed of a polymer material, such as a polycarbonate material. In preferred arrangements the support plate may be formed of a translucent polycarbonate material. In an arrangement the polymer material may be formed of MARGARD™. However, it will be appreciated that other suitable materials may be used. Where the support plates are translucent or at least partially transparent, such arrangement allows a user 125 to have visibility of the surface 120 of the assembly board 110 and to see displayed content 135 through the support plates.
The support plates 600 are configured to enable the user 125 to affix more cable holders or cable forks in a concentrated area. The support plates 600 thereby extend the spatial area available for assembling the cable harness and effectively address spatial constraints that may be encountered in the manufacture of a high density harness. The support plates by their configuration enable the user 125 to affix more forks in a concentrated area.
The support plates include a plurality of apertures 627 which is similar to apertures 227, 1227, 2227 and receiver 427 are configured to receive one or more cable fixing elements and may also be configured to receive spacer elements 400, as described above. Support plates 600 are supported at a separation from the assembly board. The separation corresponds to the height of the routing element(s) at which it is located. In some arrangements, the cable fixing element may be supported extending through the aperture to the assembly board. When a cable fixing element is received in an aperture 627, the inner surface of the aperture overlaps a portion of the support leg of the cable fixing element to retain it. The retention may be by friction fit, in addition or alternatively a fixing, for example a nut may be applied at the aperture to secure a cable fixing element therein. The support plate is configured by selection of the material, depth and form of the support plate to have strength sufficient to stably support tooling components and the cable harness. The depth T of a support plate 600 may be varied and is selected to provide sufficient overlap between the receiver and cable fixing element for secure attachment. If it is desired to provide a support plate that is translucent or transparent, the depth T may also depend on properties of the material and may be limited to depths that allow the required visibility of the assembly board through the support plate.
According to arrangements of the specification, portions of the routing elements 220, 1220 and 2220 may also be formed of a transparent or translucent material to provide improved visibility of the assembly board.
The specification provides improved routing elements 220, 1220, 2220 having a plurality of suction cups 240 located about the routing element support a combination of features which advantageously provides for an improvement in the stability of attachment between the routing elements and the assembly board and results in improved stability at the support and receiver centrally located relative to the suction cups. The suction cups are compact and provide a strong suction force for attachment of the routing element at the assembly board. Routing elements may further include guide features to allow for improved identification and control of the orientation of the routing element relative to other components and for accuracy in alignment of the routing element with other components. The support plates according to the specification define perforated ‘fixture helper’ devices that advantageously allow for affixing a greater number of forks/fixtures in a concentrated area. The support plates are configured for connection to one or more routing elements including for example to extend between two or more routing elements and the arrangement of the routing elements and support plates allow for ease of access to an increased spatial area at the assembly board than would be possible with use of conventional routing elements only.
The specification also provides a cable harness manufacturing system including an assembly board, having an attachment surface configured for receiving tooling components to support and locate the cables during manufacture and tooling components for use with the assembly board. Also provided is a kit of tooling components for use in a cable harness manufacturing system. The kit includes one or more routing elements of the different types described and one or more support plates. The routing elements of the kit are of common height and form. The support plates are dimensioned and formed for connection to and between the routing elements. For example, a support plate may have width corresponding to that of the distance between locators on the routing element. The support plates include apertures for connection to a receiver of a routing element and for receiving a corresponding protruding locator. The support plates provide for support of cable holders and cable fixing tools in an area between routing elements. The kit allows use of a workspace at the assembly board that has an increased useable volume in comparison with prior art arrangements. The routing elements described have improved stability and suction force and are configured for use with an assembly board that may be positioned at an angle to the horizontal While this invention has been described in terms of the preferred embodiments thereof, it is not intended to be so limited, but rather only to the extent set forth in the claims that follow. For example, the above-described embodiments (and/or aspects thereof) may be used in combination with each other. In addition, many modifications may be made to configure a particular situation or material to the teachings of the invention without departing from its scope. Dimensions, types of materials, orientations of the various components, and the number and positions of the various components described herein are intended to define parameters of certain embodiments and are by no means limiting and are merely prototypical embodiments.
Many other embodiments and modifications within the spirit and scope of the claims will be apparent to those of skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference to the following claims, along with the full scope of equivalents to which such claims are entitled.
As used herein, ‘one or more’ includes a function being performed by one element, a function being performed by more than one element, e.g., in a distributed fashion, several functions being performed by one element, several functions being performed by several elements, or any combination of the above.
It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact.
The terminology used in the description of the various described embodiments herein is for the purpose of describing embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “includes,” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.
Additionally, while terms of ordinance or orientation may be used herein these elements should not be limited by these terms. All terms of ordinance or orientation, unless stated otherwise, are used for purposes distinguishing one element from another, and do not denote any order of arrangement, order of operations, direction or orientation unless stated otherwise.
