Definitions

  • the invention relates to a contact element intended to be removably mounted on a wiring duct with a substantially U-shaped cross-section, said duct, on its inner walls, being provided with continuous bare conductors having an insulating shield with a longitudinal slot, contact pins of said contact element being adapted to be inserted through a respective longitudinal slot of said shield after mounting said element on said duct, in order to be contacted under spring tension with the conductor in question, at least the earth conductor being arranged on the bottom of said duct, said contact element, moreover, being provided with laterally extending locking claws which are adapted, when mounting said element by a rotational movement, to grip behind undercut edges defining the opening of said duct, in order to lock said element in said duct.
  • a wiring duct of this kind is, for instance, known from NL-C 170 787.
  • Such wiring ducts find a still increasing application, in particular in office and factory spaces, said ducts allowing to make connections for lighting appliances in arbitrary points.
  • Auxiliary elements for making a branch connection comprise a housing to be arranged on a duct and bearing on the open side of said duct, and being provided with lateral portions adapted to being applied against the lateral walls of said duct, a rotatable body provided with claws then being inserted into the inner space of said duct, said body being provided with a projecting operating handle by means of which said body can be rotated so as to engage said claws with the duct edges.
  • the current bearing contact pins are rotated in such a manner that they are contacted with the conductors arranged in the lateral wall of the duct.
  • Such an auxiliary element might, as such, be provided with a single or multiple socket allowing to make a branch connection by means of a cord with a contact plug.
  • the whole assembly will become rather high which, in the case of visible ducts, will be unsightly, and, moreover, its manufacture is complex and, therefore, relatively expensive, since wire connections between the auxiliary element and the female contacts of the socket are to be made.
  • this contact element is characterised in that said contact element comprises a bottom plate which is wider than the duct opening and is provided, at its lower side, with an integrally moulded claw body having claws extending transversely to the longitudinal axis of said plate, this in such a manner that, after insertion into the duct and by a rotation of said bottom plate until its longitudinal axis has become substantially parallel to the duct axis, said claws will engage the duct edges, said claw body being provided with contact pins which, after insertion, are adapted to contact said current conductors, said body, moreover, having a through bore into which a grounding pin is or can be inserted so as to be contacted with said earth conductor, in that said bottom plate is provided with female contacts or contact springs connected with at least said current contact pins, and in that said contact element comprises a detachable cap which, after locking said bottom plate on said duct, can be fixed on said bottom plate, the edge portions of said cap then engaging the edge portions of said duct so as to secure
  • This contact element which has a very small height is used for all the applications, and only this cap is then to be adapted to the different possibilities of use, such as for sockets with or without an earth connection, a switch element or the like. Mounting said bottom plate on a duct takes place in a very simple manner, no operating handle being needed thereto, and the eventual securing against rotation is provided by said cap.
  • This contact element is not exclusively intended for the ducts as described in NL-C 170 787, but can also be used with ducts of a different type, provided that its contact pins are adapted to the position of the conductors of such a duct.
  • the contact element shown in the drawing comprises a bottom plate 1 and a cap 2.
  • the bottom plate is adapted for being mounted on a wiring duct 3.
  • the duct 3 as shown is the wiring duct according to NL-C 170 787, but the invention is not restricted to the application thereof to such a duct.
  • the bottom plate 1 is provided in its central portion with a projecting and integrally formed claw body 4, said body having a core 5, a claw edge 6 and a projection 7.
  • the claw edge 6 is, in the tranversal direction, wider than in the longitudinal direction, as shown in fig. 2.
  • the core 5 is substantially circular, but the projection 7 has, in the transversal direction of Fig. 1, a smaller thickness than in the longitudinal direction of Fig. 2.
  • the bottom plate is provided with circumferential upstanding walls 8 defining a box-like space on which a cover 9 is fixed.
  • the bottom plate is to be fastened on the duct 3.
  • the bottom plate is placed with its longitudinal direction transversely to the longitudinal direction of the duct 3, and its claw body 4 is inserted into the duct 3.
  • This duct has inwardly directed longitudinal edges 10 defining its opening, the free space between these edges 10 being smaller than the largest width of the claw edge 6. If, then, the bottom plate 1 is rotated, the wider part of the claw edge 6 will grip behind these edges 10, so that the bottom plate 1 is fixed on the duct 3.
  • the duct 3 also possesses two lateral cavities 11 and a bottom cavity 11′, in which hollow resilient conductors 12 and 12′ resp. are arranged, which cavities each are provided with an entrance slot 13 and 13′ resp.
  • NL-C For further particulars of such a duct, reference is made to the above-mentioned NL-C.
  • two strip-like conductors 14 extend which, on the one hand, are situated laterally of the projection 7, and have, there, an extremity 14′ bent outwards, said extremities, which the bottom plate 1 has been rotated in the operative position as shown in Fig. 1, projecting into the corresponding slot 13, and will contact, there, the respective conductor 11.
  • said strips are bent outwards in the box-like portion within the walls 8 at 14 ⁇ , and, there, each strip is connected with a corresponding contact spring pair 15, e.g. by means of a rivet connection 16.
  • Each pair of contact spring strips 15 forms a contact spring, and the extremities thereof are bent at 17, and this in such a manner that both strips are adapted to engage opposite sides of a contact pin inserted through a hole 18 in the cover 9.
  • annular projections 19 are formed on the bottom plate 1 acting as a seat for such a contact pin.
  • the cap 2 shown mainly corresponds with the cap of a double wall socket, in the case shown a wall socket with earth contacts.
  • This cap 2 has a recessed portion 20 for accommodating a contact plug, the botton 21 of said recess being provided with holes 22 corresponding with the holes 18 in the cover 9.
  • a conducting strip 23 is arranged, which is provided with two pairs of earth contact springs 24 projecting inwards through slots 25 into the recesses 20 in question.
  • a long flat pin 26 is connected with said strip 23. Said pin extends, in the mounted condition of the cap, through a hole 27 in the cover 9, and into a corresponding slot 28 in the body 4, said pin being so long that it projects through the slot 13′ of the bottom cavity 11′ of the duct 3 for making contact with the grounded conductor 13′.
  • said strip 23 serves to support mounting screws 29 to be screwed into screw holes 30 of the bottom plate 1 in order to fix the cap.
  • Both terminal walls 31 of the cap 2 are provided with a recess 32, having a width which is equal to that of the duct 3. In the mounted condition, the edges of said recesses grip around the duct 3, thus securing the bottom plate against rotation.
  • the extremities 14′ of the strips 14 should be adapted accordingly.
  • the extremities 14′ should be directed downwards.
  • the portion of the body 4 carrying these contact strips 14 should not hinder the rotation of the plate 1.
  • This can be obtained by accommodating said strips 14, and, as the case may be, also the grounding pin 26, in a core of the body 4 which is rotatable in the interior of said body, and is, for instance, maintained by means of a spring in such a position that, when inserting the body 4 in a duct 3, the various contact pins will be situated in the correct position in front of the bottom conductors.
  • the connection with the contact spring strips 15 can be formed, for instance, by contact points at the upper end of the rotatable core, which will contact said strips 15 only in the rotated position of the plate 1.
