DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1 and 2 illustrate a rail 10 according to one exemplary embodiment of the invention, for connecting a plug socket, e.g. according to FIG. 4. The rail 10 comprises an outer covering 11 and an internal rail 12.
The external covering 12, which is made of a suitable material, such as plastic, in suitable oblong sections comprises, beside the receiving space 14, a second space 15, e.g. for receiving other cables or the like.
The receiving space 14, which is substantially T-shaped, is arranged to receive a connector unit, which will be described thoroughly further below. The receiving space is a channel which extends substantially along the entire rail's length and comprises one or several connector parts 16a-16e arranged parallel in the longitudinal plane of the rail and an insertion part 13 perpendicular to the connector part but having an open end towards one side of the rail.
The connector parts 16a-16e are arranged as resilient foils inserted in corresponding channels 17a-17e in the inner rail 12. The connector parts 16a-16c are resiliently arranged mainly towards the center axis of the inner rail.
The receiver space, which is substantially T-shaped, has different dimensions, according to the drawing, an upper wider and a lower smaller channel (in the plane of the drawing) and comprises further tongues 18a and 18b in each gable section of the space having variable sizes.
Moreover, the inner rail comprises the space 19 for reception of the outer covering 11. The outer covering 11, mainly being provided for decorative reasons, can be made of a suitable material, such as plastic, aluminum or the like, and is snapped in the mentioned receiving spaces 19 by means of snapping parts 111 on the backside of the covering 11. This allows using several different types of fronts for the rail depending on, e.g. environment, within which the rail is used.
FIG. 3 illustrates a side view of a connector unit 30 according to the invention. The connector unit 30 comprises a neck 31, which on one side is provided with a transverse beam 32. The beam, which is connected to the neck 31 substantially at its middle section, is arranged with variable dimensions at each side of the neck, formed as two substantially U-shaped and/or V-shaped ends 34a and 34b, respectively. The beam is provided with contact surfaces 33a-33d near each end on the surface. Obviously, the contact surfaces may also be provided on the inside of the U-shaped ends. A contact surface 33 is also arranged on the neck 31. The contact surfaces 33a-33e are coupled out of the neck through conductors 35 through the neck 31. The connector part may be arranged as spring by means of a resilient part, which extends from the beam's lower part. Preferably, the neck and the beam are made in one piece from a non-conductive material, such as plastic.
The U-shaped and/or V-shaped ends 34a, 34b are formed to fit into the above-mentioned receiver space's tongues 18a, 18b in the rail.
The connector part 30 may be connected to the backside of a conventional or especially made socket 40, FIG. 4, to couple and lock the socket to the rail according to the invention. Electrical connectors, e.g. in form of wires 41 are connected between the connector part's contact surfaces 33a-33e, the holes 42 and ground connections 43, respectively, according to the illustrated embodiment. The connector part may either be provided with conductive surfaces from the connection surfaces to the neck where the wires are connected or the wires or conductive surfaces may be arranged on the inside of the connector part, as mentioned earlier.
The varying size of the beam allows the connector part to turn and be positioned only in one way within the receiving space and accordingly contact right conductors.
The rail may be manufactured in long pieces and cut to the desired lengths. By means of a joint unit 50, as shown in FIG. 5, the rails can be joined wherever needed. The joint unit 50, which according to this example is substantially cross shaped, comprises insertion part 51 and a central portion 52. The insertion part is arranged to fit the form of the receiving space in the rail and has a cross section substantially similar to the T-shape of the connector part 30. In same way as the connector part 30, the joint unit is provided with connections surfaces 53a-53d for contacting the joined rails.
A corner part 60, illustrated in FIG. 6, may be used to connect the rails at the corners. The corner parts are made in same way as the joint unit, which was described above. The corner part may be angled in different directions and degrees. The embodiment illustrated in the drawing is partly covered with an outer covering.
Besides the corner part, other parts such as T-shape or cross connections may also occur for dividing conductors in different directions.
FIG. 7 illustrates an end piece 70. The end piece is intended for termination of the rail and isolation of the conductors where the rail ends.
The notch 13 in the outer covering 11 can cover the opening of the channel 12 and may be a weakening in the covering material. The inner rail may be provided with different screw bores for installation in different spaces or environments. When installing, the inner rail can is fastened first and after which the covering is snapped on. The rail can be manufactured in different lengths, which can be cut to desired lengths. Fitting units can be produced for connecting at the ends such that two rails can be connected, e.g. by means of drilled holes on a wall or when changing direction.
FIG. 8 shows connection procedure for connecting a plug socket, e.g. the one according to FIG. 4, to the rail. In a first position, illustrated by hatched lines, the socket is positioned horizontally on the rail and pushed into the notch and the substantially T-shaped channel in the inner rail. Then the socket is turned counter clockwise or clock wise, in about 90 degrees. Spring-load may be used to press the T-shaped connector part from the back plane and rest on an opposite surface in the substantially T-shaped channel and thereby locking the plug socket in place. Naturally, this procedure depends on the positioning of the connector part with respect to the socket.
The conductors in the rail may be of different types, electric cables (two or three phase), signal wires, e.g. telephone wires, or different types of data signals, for connection to a computer network, such as ADSL, XDSKL. Of course, a combination of electrical conductors and other conductors may occur.
FIG. 9 illustrates a second embodiment of the socket 90, comprising several types of electrical plugs 91 and 92, telephone socket 93, Ethernet connection 94, USB connection 95 and Firewall connection 96. Of course, optical fibres with optical connectors may also be used.
FIGS. 10a and 10b show two different embodiments of the inner rail 12. According to FIG. 10a, the tongues 18a and 18b are shaped substantially square. According to FIG. 10b, the tongues are missing and connection surfaces 16a-16d are provided on the bottom surface of the rail.
Moreover, other apparatuses such as surge protection, timer, residual current device, etc., may also be installed in the rail, e.g. by using a module.
The invention is not limited to the illustrated and described embodiments. The invention may be varied in a number of ways within the scope of the attached claims depending on the needs.
