Description

ELECTRICAL CONNECTION DEVICE The present invention relates to electrical connection devices for transmitting electrical signals between a body member and a closure member such as a door or a window movably mounted on it.
An increasing number of doors particularly vehicle doors are now automatically or remotely actuated and for this reason there is an increasing danger of the doors causing injury to people who become trapped by such a door.
In the case of vehicle doors the danger is particularly acute as there is a possibility that a person who is trapped by such a door may be dragged along by the vehicle and possibly injured or killed. The premature opening of a vehicle door while the vehicle is still in motion is also undesirable for a number of reasons. One way of reducing the chance of a vehicle moving off while a person is trapped by the door is to provide the door with sensing means capable of generating an electrical warning signal for transmission to the vehicle driver to warn him of such a situation and for actuating interlocks to prevent the vehicle from moving away. Alternatively the door may be controlled so as to open automatically if the door is prevented from closing completely.With such a solution however there is a requirement to pass electrical signals between the body member and the door along electrical conductors which will be repeatedly flexed. In the case of a bus the doors may be opened and closed up to 300 times per day and it has been found that when ordinary wires containing round copper conducting members are used to accommodate movement between the body and the door the life of the wire may be as little as a few weeks. A similar problem is encountered where there is a requirement to prevent a vehicle door from opening while the vehicle is still in motion as may be necessary for any passengercarrying vehicle. In such a situation it is necessary to convey an electrical signal to the door in order to actuate a locking mechanism.
In the case of certain bus doors the problem of conveying electrical signals from the body to the door is particularly acute as the door slides along a track in addition to rotating.
An object of the invention is to provide an electrical connection means for the above application which is capable of accommodating the repeated flexing described above without becoming damaged.
The inventors have found that flat conductor cable i.e. a flat section cable containing one or more conducting paths each of which is constituted by a ribbon like conducting element is capable of withstanding the repeated flexing described above. Such cable also has the advantage of deforming in a relatively predictable manner when flexed which means that with careful design wear of intermediate portions of the cable by rubbing can be avoided.
Thus according to one aspect of the invention there is provided a device suitable for connecting electrical circuits fixed to a body member and a closure member respectively the closure member being mounted to movably close an aperture in the body member the device comprising;housing means adapted to be physically fixed with respect to one of the members, and at least one length of flat conductor cable as herein before defined provided with electrical end connections for connection to the said circuits the or each length of flat conductor cable being disposed so as to flex in order to accommodate movement between the members An electrical connection device according to the invention will provide a solution to the problems referred to above by providing a conducting path which is capable of repeated flexing without breaking down.The provision of the housing means adapted to be physically fixed to one of the members provides protection for the cable and may conveniently be used to locate on end of the cable with respect:to one of the members. The use of flat conductor cable is particularly advantageous for a further reason in that it has been surprisingly found that such cable can be folded in order to effect abrupt changes of direction of its longitudinal axis without damaging the cable. This ability to fold the cable in combination with the ribbon like form of such cable enables the cable to be routed through very small spaces, and around sharp corners.
Where the device has to accommodate translational movement of the two members the device preferably includes at least one length of flat conductor cable which is disposed as a bight having first and second ends which are adapted for movement with the body member and the closure member respectively the bight being disposed in the housing means so as to accommodate translational movement between the members by rollingly transferring cable from one side of the bight to the other side. The manner in which flat conductor cable rollingly transfers cable from one side of a bight to the other means that a significant length of cable is used to accommodate translational movement between the members and repeated flexing and unflexing of the same part of the cable is thereby avoided.
Where a length of cable is disposed as a bight the bight is preferably accommodated within a channel shaped part of the housing means so as to provide a compact protection means for the cable which allows redistribution of the cable from one side of the bight to the other.
When the closure member rotates with respect to the body member the device preferably includes an arc of flat conductor cable and where the rotation is significantly large the device more preferably includes a spirally configured length of flat conductor cable. When opposite ends of flat conductor cable are angularly displaced a significant length of the cable accommodates the angular variation and as a result undesirable localised bending and unbending of a small region of the cable is avoided.
When the device is intended to accommodate rotational movement between the bodies the device preferably includes a pivot housing part of the housing means accommodating a pivot means which holds a first end of an arcuately disposed cable the other end being held by the pivot housing. Each of the pivot housing and the pivot means being rotationally fixed with respect to one of the members.
With an arrangement such as that described above the pivot means preferably includes a bushing having a slot parallel to a central axis of the pivot means into which the said first end is clamped. This arrangement is particularly advantageous because where the cable is connected to the pivot means it can be folded so as to route an end of the cable out of the plane containing the central longitudinal axis of the spirally disposed length of cable. The clamping of such a fold is desirable in order to avoid localised flexing of the cable at the location of the fold.
Where the device is adapted to convey electrical signals between a body member and a door which is constrained to simultaneously rotate and slide with respect to the body member the device preferably includes a bight of cable and a spiral of cable housed as described above in order to accommodate translational and rotational movement respectively between the members and the outer housing is preferably adapted to slidingly engage the channel shaped part of the housing means.
As it is common for such a sliding and rotating door to be guided by the movement of a door mounted roller in a body mounted track the pivot means preferably includes a track engagement device in order that the device can be easily retro fitted to existing door arrangements.
As a result of wear in such rollers and tracks there is a tendency for significant movement of the door to occur in a direction perpendicular to the track. In order to prevent this movement from being transmitted from the pivot means to the channel shaped housing via the outer housing part of the pivot housing the pivot means is preferably displaceable with respect to the outer housing in a direction substantially perpendicular to a longitudinal axis of the channel shaped part of the housing means.
The device preferably includes a single continuous length of cable in order that plug in connections can be avoided. Such an arrangement virtually eliminates the possibility of the device's operation being impaired by water entering the device and considerably reduces the cost of the device due to the elimination of expensive plug connections. This advantage is particularly important when the device is used on a bus as it is common for buses to be washed daily by automatic washing devices which squirt water jets at the bus.
The flat conductor cable preferably.includes one or more conducting members each of which is made of a metal or alloy which is not substantially work hardenable (i.e. a beryllium/copper alloy). The lack of work hardening will increase the life of such a device as it will reduce the tendency of the conducting paths to become damaged under the action of repeated flexing.
Where the device is to be fitted to a vehicle in order to transmit a signal to the driver warning him when something is caught in the door or automatically open the door the circuit accommodated within the door is preferably provided with a pressure sensitive edge strip.
Thus according to another aspect of the invention there is provided a pressure sensitive edge strip including a deformable tubular member through which a light source positioned at one end of the strip projects light which is detected by a sensor located at the other end of the strip.
Preferably the sensor is connected to circuitry which is capable of sensing a reduction in the percentage of light received. Such an arrangement may be tuned to be very sensitive and detect very slight deformations of the tubular member.
The invention will now be described by way of example only with reference to the accompanying drawings in which: figure 1 shows a schematic plan view of a pair of doors each of which is electrically connected to the body of a vehicle by means of a device according to one embodiment of the invention figure 2 is a cross section on the line BB of the device according to the embodiment shown in figure 1 figure 3 is a cross section of the device shown in figure 2 on the line CC figure 4 is an exploded view of certain parts of the pivot housing part of the device shown in figures 2 and 3 figure 5 is an elevational view of the continuous length of flat conductor cable used in the device shown in figures 1 to 4 figure 6 is a schematic elevation of a single door with a pressure sensitive edge strip and is an embodiment of a second aspect of the invention figure 7 is a cross section of the edge strip shown in figure 6 on the line GG.
Figures la and 1b show two doors 2 which are movable between a closed position shown in figure la and an open position shown in figure lb. As each door starts to move under the influence of an actuator which is not shown it pivots about a pivot means 10 and the pivot means urges a pivot housing 12 along a channel 14 which is fixed with respect to the body 4. A suitable material for the pivot housing is Nylatron (RTM).
Electrical connection is made between a circuit fixed to the body 4 (terminations of which are shown at 18) and a circuit fixed to the door (not shown) by means of a continuous length of flat conductor cable 16 (hereinafter referred to as cable). A length of cable is disposed as a bight or loop 16a located in the channel 14. One end of the bight is connected to a socket 20 and the other end is connected to a projection 13 of the pivot housing 12 which slidably engages a wall of the channel.
The pivot housing and the manner in which the cable is routed through the it will now be described in detail with reference to figures 2 to 5.
In the base of the pivot housing there is a hole 21 through which an upstanding bush 30 connected to a door plate 28 projects. A suitable material for the door plate 28 is Nylatron (RTM). As can be seen from figure 3 the door plate bush 30 can move with respect to the pivot housing in a direction perpendicular to the channel 14, relative movement of these members parallel to the channel is not possible. A resilient bushing 22 of Nylon 66 (RTM) is engaged inside the door plate bushing by means of a rib 26 at its lower end. A split ring 40 of Nylon 66 (RTM) is engagable in a groove 42 near the upper surface of the pivot housing. The door plate 28 is rigidly connected to a pivot pin plate 32 which supports a pivot pin 34. The hexagonal pivot pin extends up through the resilient bushing 22 and extends upwardly from the top of the pivot housing 12.An upper end of the pivot pin bears a. roller 36 which is rollingly engagable with a track 38 mounted on the vehicle body. If the track 38 becomes worn or misaligned with the channel 14 the possible movement between the door plate bush 30 and the pivot housing 12 means that undue lateral strain will not be placed on the connection between the pivot housing and the wall of the channel 14.
At the end of the bight 16 of cable which travels with the pivot housing 12 the cable has a first and second folds 44 and 46 (see figure 5). This section of cable is clamped by a first clamping block 15 to the pivot housing.
An intermediate portion 16c of the cable extends along an upper face of the pivot housing where it is clamped by a second clamping block 19. Where the cable reaches a down wardly.extending grove 11 in the pivot block the cable is folded again at third fold 48 in order to extend down the groove. In a lower region of the groove 11 the cable is folded again at fourth fold 50. A spiral of cable 16b then extends inside the pivot housing around the outside of the two bushing members 22 and 30. An inner end of the spiral 16b of cable is accommodated in a slot 24 in an upper region of the resilient bushing 22. Inside this slot the cable is folded at fifth fold 52 so as to extend downwardly to pass between the two bushing members 22 and 30, then between the door plate 28 and the pivot pin plate 32 and on into the body of the door.
As the pivot housing moves from the position shown in figure la to that shown in figure 1b cable is- transferred from one side of the bight 16a of cable to the other in a smooth rolling action.
As the door plate 28 and associated door plate bush 30 rotate the rotational movement is accommodated by flexing of the complete length of the spiral 16b of cable.
While plug connections may replace the folds in the tape this is undesirable as such connections would have to be made watertight. The particular advantage of the arrangement described above is that a single continuous length of cable may pass from the door to the vehicle body and because of the nature of the cable used and the manner in which it is clamped and flexed repeated opening and closing of the doors is possible without damaging the cable.
Figures 6 shows an elevation of the door shown in figure 1 as seen from the direction of the arrow F. The door has a pressure sensitive edge strip 58 of rubber which is shown in horizontal cross section in figure 7. A light emitter 54 is located at the top of the strip 58 and a light sensor 56 is located at the bottom of the strip.
Circuitry is connected to the light sensor in order to detect when the strip has been distorted. It does this by sensing when the amount of light being received by the sensor has been reduce by a certain percentage. Such an edge strip is capable of detecting very slight deformation of the strip such as that caused by a bag which has been trapped inside the vehicle and which is being pulled by its strap from outside the vehicle.
In an alternative arrangement, the light emitter 54 may be located at the bottom of the strip 58 and the light sensor 56 may be located at the top of the strip.
Whilst a particular embodiment of the invention has been described, various modifications will be envisaged without departing from the scope of the invention. For example, the cable may consist of a bight portion only for use on closure members which are only slidably movable, or alternatively may consist of a spiral portion only for use on closure members which are only rotatable.
