Description

<Desc/Clms Page number 1>
PANEL This invention relates to panels, especially laminate panels. The invention is particularly but not exclusively applicable to laminates comprising carbon fibre.
Laminate materials comprise two or more layers laminated together. Often the layers are of different materials, so that the resulting composite laminate can benefit from a combination of the properties of those materials. One use for laminate materials is in body panels for vehicles. Laminate composite body panels can, for example, include layers of resin-reinforced carbon fibre for high strength and light weight.
Figure 1 illustrates one form of resin reinforced carbon fibre panel. Figure 1 is a cross-section through the panel. The panel comprises two sheets 1 of carbon fibre fabric which are impregnated with a resin which forms a matrix 2 around the carbon fibre. There may be a flow medium present to improve the flow of the resin around the sheets of carbon fibre.
Although carbon fibre and other composite panels are advantageous in that they are lighter and stronger than comparable conventional steel or aluminium body panels, they have some significant disadvantages, especially in the attachment of electrical fitments such as vehicle indicator lamps. When conventional metal panels are used, indicator lamp assemblies are typically clipped into holes that have been drilled or stamped into the panels. Thus in the manufacturing process it is straightforward to locate and attach the lamp assembly. A wire is connected to the lamp assembly to provide current to the lamp and the return path for the current is made through the metal of the panel itself. The use of the panels to provide a current return path greatly simplifies the wiring. In contrast, carbon fibre panels are normally substantially non-conductive, so they cannot be used to provide a return path for current, and additional wiring is needed instead. Furthermore, conventional panels are generally include reinforcing structures, for example of box form, which can double as cable channels. In contrast, carbon fibre panels often need no such
<Desc/Clms Page number 2>
structures, and so it is problematic to route the additional wiring that is necessitated by normal carbon fibre panels.
There is a need for a panel that addresses the above problems.
According to one aspect of the present invention there is provided a panel connector arrangement comprising: a panel having electrically insulating external faces and a region of electrically conductive material located between the external faces, there being a bore extending through the panel between the external faces; an electrical component having a head and an elongate leg extending from the head for passing through the bore, the leg having an electrically conductive surface; and an electrically conductive fastener having a body and at least one tooth extending from the body, the fastener being arranged for attachment to the leg in a configuration in which the tooth extends towards the head; the leg and the fastener being cooperatively configured so that during attachment of the fastener to the leg the fastener is drawn towards the head, whereby when the electrical component is arranged with its head against one extemal face of the panel and its leg extending through the panel, on attachment of the fastener to the leg the tooth is drawn to bite through the other extemal face of the panel to meet the electrically conductive material and thereby make electrical contact between the leg and the electrically conductive material Preferably the etectrtcaffy conductive surface of the leg constitutes an input or output contact of the electrical component. The electrical component suitably has another input or output contact, which may be at the end of the leg opposite the head.
The fastener is most preferably rotatably attachable to the leg. For this purpose the leg suitably has an external thread means and the fastener has an internal thread means for engagement with the thread means of the leg. The thread means may be a thread or set of threads or a partial thread. The fastener is conveniently a nut.
The fastener may have two or more teeth. The teeth are preferably sharp.
<Desc/Clms Page number 3>
The bore preferably passes through the said electrically conductive material.
The electrically conductive material is preferably the form of an elongate track having an enlarged portion around the bore.
The panel may include a plurality of bores passing through the said electrically conductive material.
The panel may include switching circuitry connected to the electrically conductive material for modifying the supply of current through the electrically conductive material.
According to a second aspect of the present invention there is provided a vehicle body panel having electrically insulating external faces and a plurality of conductive strips running through the panel between the faces and terminating in electrical connectors at the surface of the panel ; whereby past deformation of the panel may be detected by measuring conductivity between the connectors and thereby detecting disruption of the conductive strips.
According to a third aspect of the present invention there is provided a method for testing a vehicle body panel to detect past deformation of the panel, the panel having electrically insulating external faces and a plurality of conductive strips running through the panel between the faces and terminating in electrical connectors at the surface of the panel ; and the method comprising measuring conductivity between the connectors.
The present invention will now be described by way of example with reference to the accompanying drawings, in which: figure 1 shows a cross-section of a conventional carbon fibre body panel ; and figure 2 shows a cut-away view of a composite body panel including a circuit board, together with components for attachment to the panel.
<Desc/Clms Page number 4>
In figure 2, part of a composite body panel is shown generally as 10. The panel includes two structural outer layers 11,12. Between the layers, for part of their area, is an electrically conductive layer 13. The electrically conductive layer can serve as a path of current to or from a fitment that is attached to the panel.
The structural outer layers could be formed of any suitable material. However, the advantages of the conductive layer are emphasised when the structural outer layers are substantially electrically non-conductive. Preferred materials for the structural outer layers include plastics sheet and reinforced fibre materials such as reinforced carbon fibre, reinforced glass fibre and reinforced Kevlar. The fibres could be knitted or woven into a cloth. The reinforcement could be a resin such as an epoxy resin.
The structural layers of the panel are preferably bonded together firmly where they meet outside the periphery of the conductive layer. If necessary, holes could be provided in the conductive layer so that the structural layers can bond together within the outer periphery of the conductive layer.
The conductive layer may conveniently take the form of a sheet of conductive material, for example a sheet of aluminium, gold or stainless steel or of a conductive polymer. Such a conductive layer could be cut to shape from a larger sheet and then layered in place between the structural layers during manufacture of the panel. Alternatively, the conductive sheet coutd be deposited on the interior surface of one of the structural layers before the structural layers are joined together.
Alternatively, the conductive layer could be provided as a conductive track integral with a non-conductive carrier. The carrier bearing the track could layered in place between the structural layers during manufacture of the panel. The carrier could be rigid, but a flexible carrier-for example in the form of a sheet-could be more convenient to layer into the panel. The conductive material is suitably coated on the sheet. The conductive material could cover the whole of the carrier as layered Into the panel, or just part of it. The conductive material could be selectively coated on the carrier, for example by printing. In one preferred arrangement the carrier with its
<Desc/Clms Page number 5>
conductive layer take the form of a printed circuit board. The pattern of the conductive material on the carrier is suitably defined so as to suit the configuration of the panel in which it is to be incorporated-for example to bridge conveniently between locations on the panel between which electrical current is to be carried. A circuit board of the type described above could conveniently include active electrical components in electrical communication with the conductive track.
Alternatively, at least part of the conductive layer could be provided as a conductive wire.
Figure 2 also illustrates one route by which an electrical fitment such as in indicator lamp assembly could be mounted to a non-conductive panel that incorporates a conductive layer. The lamp assembly 22 includes a bulb. The lamp assembly has a threaded leg 17. The outer part of the threaded leg is electrically conductive and is connected inside the lamp assembly to one terminal of the bulb of the lamp. The other terminal of the bulb is connected to a conductor that passes through the centre of the leg and terminates in a connector lug 21. Inside the leg the outer part of the leg and the conductor are insulated from each other.
A hole 14 is provided through the panel at the location where the lamp assembly. is to be attached. The hole is sized to receive the threaded leg.
A back nut 18 is used to connect the lamp assembly to the panel both physically and electrically. The back nut is electrically conductive. The back nut is threaded for engagement with the leg 17. The back nut carries electrically conductive teeth 19,20 which extend axially from the body of the nut. The teeth are preferably sharp, and extend from the radial surface of the back nut by a little more than the thickness of the rear structural layer 12 of the body panel.
To fit the lamp assembly to the panel the leg 17 is inserted through the hole 14. Then the back nut is threaded on to the leg with the teeth 19,20 facing the panel. As the back nut is screwed on to the leg the teeth are drawn to meet the panel and as
<Desc/Clms Page number 6>
the back nut is screwed further the teeth scrape into the rear of the panel, eventually reaching the depth of the conductive layer 15 and making contact with that layer.
The back nut is tightened to hold the lamp assembly in place against the panel. At that stage the conductive layer 15 is electrically connected to a terminal of the bulb of the lamp assembly by way of the teeth 19,20 ; the nut 18 and the outer surface of the leg 17. To make the other connection to the bulb a wire can be clipped to lug 21.
Means are preferably provided to resist rotation of the lamp assembly as the back nut is being fitted. For example, the hole 14 could be non-circular and the lamp assembly could include projections that engage with the sides of the hole. Optionally the hole could be internally threaded, or the external thread on the leg could be self- tapping.
To allow the back nut to engage reliably with the conductive track, the track is preferably relatively wide in the region of the hole 14. Elsewhere in the panel, it may be preferred that the track is relatively narrow to avoid it weakening the panel significantly. The track can therefore conveniently take the form of a narrow conductive strip 16 over the majority of its length, with an enlarged region 15 at the hole 14.
Instead of a the backnut as shown in figure 2, a conventional backnut could be used if in a particular embodiment the outer surface of the teg 17 were found to make a sufficiently reliable connection directly to the strip 16.
The conductive layer can conveniently be used as a distributed earth for the unit of which the body panel forms part. In that case it is suitably in the form of a track which extends between a number of locations on the panel to which apparatus is to be connected.
At the edge of the panel the conductive layer terminates in a connector or contact by means of which it can be connected to the other electrical components of the unit.
<Desc/Clms Page number 7>
The body panel could be the body panel of a vehicle, such as a car, or of another unit such as a domestic or industrial appliance, for instance a washing machine or a television. The body panel suitably provides the outer structural part of the unit.
As indicated above, active electrical components can be provided together with the conductive layer within the panel. In one example, the components could define a flasher circuit for a lamp connected to the conductive layer. The flasher circuit can alternately make and break the connection to or from the lamp so that it is caused to turn on and off. In another example the components could define a temperature sensor for providing feedback on the temperature of the panel.
The conductive layer could be provided as a set of fragile elongate conductors running across the panel from one contact at the edge of the panel to another. When the panel suffers damage, for example due to an impact on the panel, one or more of the conductors may be fractured, and this may be sensed as a loss of continuity between the external connectors. In this way damage to the panel can conveniently be detected.
To form the panel the structural layers 11,12 could be completed and then bonded together with the conductive layer between them. Alternatively, the structural layers could be partially formed, layered together with the conductive layer and then a bonding medium impregnated about all three layers so as to completed the panel. In one example of the latter arrangement, sheets of carbon fibre fabric for strengthening respective ones of the structural layers could be layered together with the conductive layer laminated between them. Then those layers could be impregnated with resin.
The conductive layer may be integrated with or may take the form of a flow medium that can enhance the flow of reinforcing resin in the formation of the panel.
The applicant draws attention to the fact that the present invention may include any feature or combination of features disclosed herein either implicitly or explicitly or any generalisation thereof, without limitation to the scope of any of the present claims. In
<Desc/Clms Page number 8>
view of the foregoing description it will be evident to a person skilled in the art that various modifications may be made within the scope of the invention.
