Description
A CONNECTOR DEVICE
FIELD OF THE INVENTION
The present invention relates to an electrical connector device adapted to being fitted in a vehicle and to facilitating the connection of at least one external electrical conductor to the vehicle, which connection device comprises at least one electrically conducting connecting element housed in a chamber, which connecting element comprises a connecting portion suitable for electrical connection of the external electrical conductor to the connecting portion.
STATE OF THE ART
A known practice is to connect external electrical conductors to vehicles. An example of such an electrical conductor is starting cables which are connected to a vehicle's battery in order to charge the battery if it becomes discharged. A problem with the connection is that the battery is concealed within the vehicle's bonnet, so it is difficult to have access to.
Patent specification WO 06130071 refers to a connector device for a starting cable, which is fitted in a space in the bodywork. The connection is accessible after removal of a cover for the space. A problem with that device is that it may still be difficult to connect a starting cable to the connector device because of lack of space.
SUMMARY OF THE INVENTION
An object of the present invention is to propose an improved connection for connecting an external electrical conductor to a vehicle.
This object is achieved with a connector device according to the preamble of claim 1 which is characterised in that the connector device comprises an aperture to the chamber which houses the connecting element and that the electrical connecting element is movable between a first state in which the connecting element is protected within the chamber and a second state in which the connecting element is brought out of the chamber through the aperture.
The connecting element being brought out of the chamber in the second state thus facilitates the connection of the external cable to the connecting element. This is particularly advantageous if the contact by which the external electrical conductor is connected to the connecting element is large and cumbersome. It also makes it easier to connect the external electrical conductor from various directions to the connecting element, since the connecting element is accessible from all directions when it is brought out from the chamber. At the same time, the connecting element is protected when it is in the first state, both with regard to physical damage and with regard to undesired electrical conduction.
The connector device is preferably so located that the aperture is situated on a readily accessible surface, preferably an outer surface, of the vehicle. This makes it easy for a person to connect the external electrical conductor to the connecting element. The connection device is preferably located within the vehicle's body and in such a way that the aperture is situated on the outside of the body.
According to an embodiment of the invention, the vehicle comprises a vehicle battery and the electrical connector device is suitable for connecting at least one external electrical conductor to at least one pole of the vehicle battery for charging of the battery. The connector device is preferably suitable for connecting a starting cable to the connector device, whereby the
connector device is itself connected to a pole of the vehicle battery. In an alternative embodiment, the connector device is suitable for connecting two electrical lines to the connector device. In this case, the connector device is preferably suitable for connecting a pair of starting cables to the connector device, whereby the connector device is adapted to connecting the starting cables to both poles of the battery. Alternatively, the connector device may be suitable for connecting a charging cable for charging the battery, e.g. for charging the battery of an electrically powered vehicle.
According to an embodiment of the invention, the connecting portion is elongate and suitable for connecting a terminal of the elongate connecting portion. The connecting element is preferably suitable for connecting an electrically conducting terminal on the connecting element, for electrical contact between the connecting element and the external electrical conductor. The connecting element is preferably provided with a substantially uniform cross-section along its length. The connecting element is preferably rodlike. This makes it possible for the terminal to be clamped firmly on and surround the connecting portion. The connecting portion is preferably made of an electrically conducting material and has no insulation, so that the external electrical conductor can be connected directly on the surface of the connecting portion.
According to an embodiment of the invention, at least part of the electrical connecting portion is adapted to extending at an angle out from the aperture in the second state. At least part of the connecting portion being angled also makes it easier to connect the external line to the connecting portion from various angles. In cases where the external conductor is connected to a terminal on the connecting portion, the connection is thus usually made from a direction perpendicular to the longitudinal direction of the connecting portion. If the connecting portion extends straight out from the aperture, the terminal will therefore be parallel with
the surface of the body, which makes connecting the terminal difficult. Angling the connecting portion therefore makes it possible for the terminal to be connected from a direction more straight in front.
According to an embodiment of the invention, at least part of the connecting element is arcuate. The shape of the connecting element is thus such that it extends out from the aperture at several different angles simultaneously. This makes it possible for the external line to be connected from several different directions, making it easier for a person wishing to connect the external line to the vehicle, since it increases the range of possibilities for him/her to choose from.
At the same time, the connecting element is preferably rodlike and adapted to being pulled out from the aperture along substantially the same path as its arcuate shape. This makes it possible for the aperture to the chamber to be smaller, since it need only be as large as or slightly larger than the largest cross- section of the connecting element.
According to an embodiment, the connecting element is arranged to be rotatable about an axis of rotation which runs straight out from the aperture. This makes it possible for a person wishing to connect the external conductor to turn the connecting element round to an angle which makes the connection easier.
According to an embodiment of the invention, the connecting element is configured to allow at least two different versions of connection contacts to be connected to the connecting element.
The connecting portion preferably comprises at least a first and a second section which are of different shapes so that said sections are suitable for connecting two different versions of connection contacts to the connecting portion. This increases the flexibility of the connector device in that the same connector
device can be used for connecting many different kinds of contacts to the device. The sections are preferably so configured that they are suitable for connecting two different kinds of terminals on them.
According to an embodiment, the connecting portion is configured with a cross-sectional shape which comprises a first section in the form of a first circle sector with a first radius and a second section in the form of a second circle sector with a second radius which differs from the first radius. This renders the connecting portion suitable for connecting two different terminals on the same length of the connecting portion.
According to an embodiment, the cross-section of the connecting portion is elliptical. This means that a terminal fastened to a long side of the ellipse will be significantly firmer and more secure than to a corresponding circular connecting portion. Moreover, a second terminal with a different smaller size can be fastened firmly to a short side of the ellipse. Such a connecting portion is also easy to manufacture.
According to an embodiment of the invention, the connector device comprises a covering means adapted to covering the aperture to the chamber when the connecting element is in the first state. The chamber and the connecting element are thus protected when the covering means is closed. The covering means may take the form of a hatch or the like. The covering means is preferably sealed so that water or the like will not make its way into the chamber.
According to an embodiment of the invention, the connecting element is connected to the covering means, in which case the connecting element is pulled out of the chamber by the covering means being opened. The connecting element is preferably connected to the inside of the covering means. Opening the covering element means and pulling out the connecting element
thus take place simultaneously in a single movement. It is also easy for a person to pull the connecting element out by taking hold of the covering means, which is easier to grip.
According to an embodiment of the invention, the covering means is pivotably connected to the aperture along an edge of the aperture. In this case the covering means is opened by rotation about the physical connection, and the connecting element is pulled out by an arcuate movement. The connecting element is preferably likewise arcuate. The connecting element is preferably so configured that at least part of the connecting portion is parallel with the plane of the aperture when the covering means is fully open, making it easy for a terminal to be put firmly in place and connected to the connecting portion. In an embodiment, the connection device also comprises a hinged arm connected to the rear end of the connecting element and adapted to guiding the movement of pulling out the connecting element.

DETAILED DESCRIPTION
Fig. 1 a and Fig.1 b depict schematically a body 1 belonging to a vehicle such as a passenger car, truck, bus or similar engine- powered vehicle. They further depict a connector device 3 according to an example of the invention which is adapted to being fitted in the vehicle and to facilitating the connection of at least one external electrical conductor 5 to the vehicle. To this end, the connector device 3 comprises an electrically conducting connecting element 7 housed in a chamber 9. The connecting element 7 further comprises a connecting portion 1 1 suitable for electrical connection of the external electrical conductor 5 to the connecting portion 1 1 .
The chamber 9 is defined in this example by a casing 13 but may in another example also be defined by the hollow in the body in which the connection device 3 is arranged. The connection device 3 comprises an aperture 15 to the chamber 9. According to this example of the invention, the electrical connecting element 7 is movable between a first state in which the connecting element 7 is protected inside the chamber 9 as depicted in Fig. 1 a, and a second state in which the connecting element 7 is brought out from the chamber 9 through the aperture 15, as depicted in Fig. 1 b. Bringing the connecting element out from the chamber in the second state facilitates access to the connecting element 7, making it easier to connect the external cable 5. Moreover, the connecting element 7 is protected within the chamber 9 in the first state when the connection device 3 is not being used.
In this example, the vehicle is equipped with a battery 17, in this embodiment a vehicle battery 17 to supply electrical energy to a starter motor and possibly to an ignition plug or an incandescent
wire. In an alternative embodiment, the vehicle's battery 17 may instead be adapted to powering an electric motor intended to power the vehicle. The electrical connector device 3 is suitable for connecting the at least one external electrical conductor 5 to at least one pole of the vehicle battery 17 for charging of the battery. In this example, the connection device is suitable for connecting the external conductor to a B+ pole. The connector device 3 is thus suitable for connecting a starting cable to the vehicle battery 17 via the connector device 3. The electrical conductor 5, in the form of a starting cable, comprises in this case a terminal 19 adapted to being clamped firmly on the connecting element 7 for connection of the electrical conductor 5. Correspondingly, the connecting element 7 is adapted to having a terminal clamped firmly on it.
In an alternative embodiment, the connection device may be suitable for connecting two or more external conductors to the connecting device. In the case of the connection of starting cables, the connection device may be adapted to connecting one conductor to a pole of the battery and the other conductor to the vehicle's body. In the case of a battery adapted to powering the vehicle, the connector device 3 may be adapted to connecting the second conductor to an opposite pole of the battery.
The connecting portion 1 1 of the connecting element 7 in this example is elongate and suitable for connecting a terminal on the elongate connecting portion. To this end, the connecting portion 1 1 is rodlike and provided with a substantially uniform cross-section along its length. The connecting portion is made of an electrically conducting material and the connecting portion 1 1 of the connecting element has no insulation, so that the contacts of the external conductor 5 can be connected electrically directly to the surface of the connecting portion 1 1 . In this example, the terminal 19 is clamped firmly on and surrounds the connecting portion 1 1.
The connector device 3 in this example is located within the vehicle's body 1 . The connection device is also so located that the aperture leads out on a surface of the body. In this example, the surface is readily accessible to a person, making it easy to connect the external conductor 5. In this example, the connection device 3 is also suitable for being so located that the aperture 15 leads out on the outside of the body, so that a person wishing to connect the external conductor does not have to open, for example, the bonnet or in some other way have to cope with shifting of freight or disconnecting a coach or a trailer.
The connecting portion 1 1 is further so arranged that at least part of it extends out at an angle from the aperture in the second state. As a terminal is connected perpendicularly to an elongate connecting portion 1 1 , it is advantageous if the connecting portion 1 1 is angled so that the terminal can be connected from several angles and directions. In this example, the connecting portion 1 1 comprises a section 21 which extends substantially parallel with the plane of the aperture 15. The terminal 19 is thus connected straight from in front to the connecting element 7. In a case where the connecting portion extends straight out from the aperture, the terminal would be level with the surface of the body, which might result in the connection being hindered by the surface.
In this example, at least part of the connecting element 7 is arcuate. The arcuate shape of the connecting element 7 makes it possible to connect the terminal from a large number of angles and directions, e.g. depending on external obstacles situated in the surroundings of the vehicle.
The connector device 3 further comprises a covering means 23 adapted to covering the aperture to the chamber 9 when the connecting element 7 is retracted in the chamber in the first state. In this example, the covering means is a hatch 23 but
may also be configured in some other suitable way or be omitted completely. The covering means 23 further comprises a seal arranged round its edge, to prevent ingress of, for example, water into the chamber 9.
The connecting element 7 is connected to the inside of the covering means 23. Thus the connecting element 7 is pulled out from the chamber at the same time as the covering means 23 is opened. The covering means 23 is connected pivotably to the casing 13 along one edge of the aperture 15. The connecting element 7 is thus drawn out from the aperture 15 in an arc. Owing to the simultaneous arcuate shape of the connecting element 7, the connecting element 7 is drawn out along a well- defined path from the aperture, making it possible for the aperture for the connecting element to be smaller than the dimensions of the chamber, and hence reducing the risk of dirt ingress. The connecting element 7 will also be parallel with the aperture at the end of the arcuate movement.
The connector device 3 further comprises a hinged arm 25 connected to, and adapted to supporting, the connecting element 7 and its movement. In this example the hinged arm 25 is connected to the rear end of the connecting element 7.
The connecting element 7 is further adapted to being pivotable about an axis of rotation which extends straight out from the aperture and perpendicular to the plane of the aperture. This makes it possible for the connecting element to be pivoted to various angles so that connecting the terminal 19 is facilitated. The pivotability can be achieved by causing the connecting element 7 itself to be pivotable in the chamber 9, or the casing 13 round the chamber may comprise a fixed portion and a pivotable portion fitted in the fixed portion, or the connector device 3 as a whole may be fitted pivotably in the body 1. The pivotability may be limited to, for example, a range of 60° or be unlimited.
In this example, the connecting portion 1 1 is shaped to allow the connection of at least two different versions of connection contacts 19 to the connecting portion. In this example the connecting portion is configured to allow the connection of at least two different versions of terminals on the connecting portion.
Fig. 2a depicts a first example of configuration of the connecting portion 1 1. The connecting portion 1 1 in Fig. 2a is provided with a cross-sectional shape which comprises a first circle sector 27 with a first radius and a second circle sector 29 with a second radius which differs from the first radius. Connecting two different sizes of terminals on the connecting portion is thus facilitated, since the terminal can be connected at various angles so that the terminal and the radius of the circle sector match.
Fig. 2b depicts a second example of the configuration of the connecting portion 1 1. The connecting portion 1 1 in Fig. 2b is provided with an elliptical cross-section. A terminal connected to the long sides of the ellipse will be very securely fastened on the connecting portion. This reduces the risk of the terminal becoming detached if someone or something inadvertently pulls on the terminal, which may for example happen in very cold conditions in which the cable present in the terminal may become rigid and more easily transmit forces to the terminal if, for example, someone steps or climbs on the cable. There is also a continuous spectrum of possible radii for connecting the terminal, depending on the angle at which the terminal is connected to the connecting portion 1 1. Such an elliptical cross-section is also easy to manufacture.
The connecting element 7 may also comprise connecting portions for connecting other forms of contact means than terminals, e.g. an ordinary male/female contact.
The invention is not limited to the embodiments referred to above but may be varied freely within the scope of the claims set out below.
