Definitions

  • the present invention relates to an apparatus for current or power supply and comprising an elongate rail with a front side, a rear side and two opposing side surfaces, there being disposed, in the rail, longitudinal electric conductors that are connectible to a power source, and at least one power outlet or socket disposed on the rail.
  • Current supply rails are also previously known in the art which operate with full voltage. Such rails are used, for example, in public areas, exhibition premises, shop environments and the like where extremely high demands are placed on flexible positioning of illumination fittings and other types of electric equipment.
  • Current supply rails for this purpose often display considerable dimensions and have, in their front side, i.e. that side which is turned to face away from the substrate on which the current supply rail is fixed, a longitudinal aperture opening into the interior where the electric conductors of the rail are located.
  • a connection device is, as a rule, insertable in the rail in any optional position therein and may be secured there, for example by a twisting movement so that electric contact is established.
  • a current supply rail of this type functions excellently, for example disposed in the ceiling in electricity shop where fittings often need to be taken down and put up in varying positions.
  • the prior art current supply rail cannot be used in such situations where the space is limited, principally in a direction out from the substrate on which the current supply rail is secured, for example behind shop shelves, display cases, etc.
  • the present invention has for its object to design the apparatus intimated by way of introduction such that the problems inherent in the prior art technology are obviated.
  • the present invention has for its object to design the apparatus intimated by way of introduction such that it may be employed for full mains voltage without safety issues, that it may be employed also in extremely restricted spaces with optional positioning of the outlets or power points in the longitudinal direction of the apparatus, and that it may be manufactured at low cost.
  • the current supply apparatus illustrated in Fig. 1 comprises a connection device 1, an earthed (grounded) outlet device 2, an unearthed (ungrounded) outlet device 3, an endpiece 4 and a rail 5 which serves for accommodating the above-mentioned components.
  • Fig. 1 shows a combination of earthed 2 and unearthed 3 outlet devices, which does not occur in practice since this would be contrary to valid regulations.
  • connection device I and the endpiece 4 are fixed in relation to the rail 5 and cannot be moved along it.
  • both the earthed outlet device 2 and the unearthed outlet device 3 may be displaced along the rail and positioned in any optional position therealong. Further, any optional number of outlet devices, provided that space is sufficient, may be placed on one and the same rail.
  • the rail 5 has a rear side 6 which is turned to face in towards the substrate against which the rail rests or is secured, respectively. Further, the rail 5 has a front side 7 which faces out from the substrate. Finally, the rail 5 displays opposing side surfaces 8 which are considerably narrower than the rear side and the front side. Preferably, the front side and the rear side are between three and seven times wider than the two opposing side surfaces, preferably however approximately fives times wider. As a result, the rail will have a substantially rectangular outer contour with those exceptions which will be described in greater detail hereinbelow.
  • the rail 5 displays, in its side surfaces 8, longitudinal grooves 9 which extend in towards the central region of the rail and which are defined by surfaces which are substantially parallel with both the front side 7 and the rear side 6 of the rail.
  • these grooves 9 there are disposed electric conductors 10 which extend throughout the entire length of the rail 5. These conductors 10 have free metal surfaces, at least along that part of the peripheral surface which is turned to face towards the longitudinal grooves 9 and principally their openings at the side surfaces 8 of the rail.
  • connection device 1 is in two parts, where the plane of division also includes a longitudinal centre line to the rail 5 (when the connection device 1 is mounted thereon). Both of the halves 11 and 12 of the connection device are urgeable against one another by means of screws 13 which extend through insulation sleeves 14 disposed interiorly in the connection device 1. As a result, the risk that any of the screws 13 may come into electric contact with live components interiorly in the connection device 1 is eliminated.
  • connecting means 15 which are produced from spring metal in the form of leaf springs which are L-shaped.
  • the width in the longitudinal direction of the rail 1 is, in one practical embodiment, of the order of magnitude of between 8 and 12 mm.
  • the connecting means 15 are L-shaped and have one shank 16 which engages in the longitudinal grooves 9 of the rail 5 in order to contact the conductors 10 located in the bottom of the grooves.
  • the opposite end of the connecting means 15 is accommodated in a bracket 17 which at least positionally fixes the connecting means in the longitudinal direction of the rail and in a direction out from the longitudinal centre line of the rail. This implies that, on tightening of the screws 13, the shanks 16 of the connecting means 15 will be pressed against the conductors 10, on the one hand to realise an electric contact therebetween, and also with sufficiently great force to positionally fix the connection device 1 in relation to the rail in the longitudinal direction thereof.
  • the positional fixing of the connection device transversely of the rail and transversely of the front and rear sides of the rail is realised by means of the engagement of the shanks 16 in the grooves 9 of the rail.
  • brackets 17 there are also provided connections to a conductor which is passed into the connection device I via a stress relieving device 18, see Figs. 1 and 2 .
  • connection device In order to improve the positioning of the connection device 1 in relation to the rail 5, the connection device is provided with guide heels 19 which, in the mounted position of the connection device on the rail 5, abut against both of the opposing side surface 8 thereof. Finally, the connection device has fixing lugs 20 for fixing against the substrate.
  • Fig. 1 shows both earthed and unearthed versions of the outlet device or power point 2 and 3, respectively. As was mentioned above, these are not used simultaneously on one and the same rail 5.
  • This conductor 21 ( Fig. 3 ) is an earth conductor which is connected to earth and, as a result, carries no potential.
  • This earth conductor 21 is positioned in the central region of the rail 5 in the bottom of a groove 22, Figs. 1 and 5 , which is open towards the front side 7 of the rail 5.
  • the earthed outlet device 2 In order to contact the earth conductor 21, the earthed outlet device 2 has a drag spring or some similar contactor device, which is in communication with an earth connection 23 which is intended to cooperate with a corresponding earth device in an earthed plug.
  • the construction of the earthed outlet device 2 is identical or almost identical with that which applies to the unearthed outlet device 3.
  • the unearthed outlet device 3 has inner contact members 24 which are provided for realising electric contact between the longitudinal conductors 10 of the rail 5 and the contact blades or pins on a plug inserted in the outlet device 2.
  • the contact members 24 have contact portions 25 which correspond to the shanks 16 of the connecting means 15 and which, both as regards contact with the conductors 10 and retention of the outlet device on the rail, fulfil the same function as them.
  • Choice of material and dimensioning also correspond approximately to those which were disclosed for the connection device 1.
  • the unearthed outlet device 3 has insertion openings 26 for insertion of the contact blades or pins of an unearthed plug.
  • the contact members 24 In association with these insertion openings 26, the contact members 24 have ramp portions 27 which are obliquely inclined in relation to the insertion direction of the contact blades or pins of the plug. This implies that, on insertion of the contact blades or pins in the insertion openings 26, the inner ends of the contact blades or pins will press against the ramp portions 27 and strive to move them in a direction towards one another. This in turn implies that the contact portions 25 are urged against the conductors 10 so that electric contact is established.
  • the inclination of the ramp portions 27 in relation to the insertion direction in the insertion openings 26, in combination with the resilient properties in both of the contact members 24 is selected in such a manner that the force which occurs between the contact portions 25 and the conductors 10 is sufficient, in addition to the electric contact, also to realise a mechanical retention of the outlet device 3 in the longitudinal direction of the rail 5.
  • the opposing ends of the contact members 24, thus facing away from the contact portions 25, must be prevented from moving in a direction towards one another under the action of the contact blades or pins of the plug.
  • the contact members 24 have stop portions 28 bent in a direction towards one another and abutting against an abutment portion 29 fixedly disposed in the outlet device 3.
  • the abutment portion 29 is formed as a T, where the stop portions 28 are located under the transverse crosspiece of the T.
  • the unearthed outlet device 3 also has guide heels 19 which abut against the opposing side surfaces 8 of the rail 5 so that the outlet device will as a result be better supported in relation to the rail transversely of its longitudinal direction.
  • both of the contact members 24 will lie loosely in their positions interiorly in the outlet device. This implies that the contact members 24 are free to be pivoted to some extent away from one another so that there is no electric contact, nor any direct mechanical engagement, between the contact portions 25 of the contact members and the conductors 10. In this state, the outlet device may readily be slid in the longitudinal direction of the rail 5.
  • the contact blades or pins on a plug of the so-called Euro type are relatively thin, while the contact pins of a conventional plug are of a slightly larger diameter. This implies that the exact dimensioning of the contact members 24, their positioning and the inclination of the two ramp surfaces 27 must be adapted in each individual case to the type of plug which is to be employed. Thus, dimensioning, positioning and detailed design of the contact members 24 cannot be exactly the same in an earthed outlet device 2 as in an unearthed outlet device 3.
  • the one contact member is fixedly mounted and thus not movable under the action of a contact blade or pin in a plug when the plug is inserted in the outlet device.
  • the opposite, moving contact member 24 accounts for the entire movement, both as regards establishing electric contact and as regards fixedly clamping the outlet device on the rail.
