Definitions

  • a connection plug for a current supply rail.
  • the plug comprises contact springs actuated by a control shaft between a protruding contact position and a retracted inoperative position.
  • the control shaft is formed with guiding surfaces angularly displaced with respect to each other so that the contact springs are selectively actuated and brought to protruding contact position by the control shaft.
  • the invention relates to a current connecting plug which can be inserted into the opening of an essentially U- shaped current supply rail provided on its side walls with at least three bare conductors and preferably one bare ground conductor and which is provided with contact springs and fastening springs and a longitudinal, in relation to the current supply rail, control shaft which displaces the contact springs against the conductors and the fastening springs in recessed spaces of the current supply rail by means of guide surfaces.
  • Such plugs are used for supplying current to a consumer apparatus, usually lighting apparatus, which can be directly supported by the plug.
  • the control shaft When the plug is to be inserted into the opening of the rail, the control shaft must be adjusted to a 0 position; thereafter the shaft is adjusted to its connecting position, in which the ends of the contact and fastening springs protrude from the walls of the plug and assume their operating positions.
  • the control shaft there are only two different positions for the turning movement of the control shaft. If the current supply rail has two conductors on each of its interior sides and possibly a fifth conductor on the bottom wall, it would be necessary, e.g.
  • the bar-like component has in a central extension an elongated hole with a groove recess for the control shaft passing through the hole and for the control shaft, which has a projecting part at this point, to catch in the off position (0) under the influence of a spring, preferably a compression spring.
  • a spring preferably a compression spring.
  • this contact spring will maintain the conducting connection in all the three on-positions, which is obtained so that a relatively narrow control surface on the control shaft is followed by a ring groove covering about 270 so that the contact spring concerned corresponding to the conductor is maintained in connection in all the other three on-positions.
  • the construction length of the device is shortened by the width of one contact spring in the longitudinal direction of the control shaft by combining two springs as one unit. These two metallic, correspondingly bowed strips are, for this purpose, joined together on both sides of the cage by means of riveting or by other similar means.
  • the control cam of symmetrical triangle form is arranged on the control shaft eccentrically.
  • the strip-like contact spring is in the central cage area firmly connected with a shorter handle-like metal strip by means of riveting or similar means, whereby this shorter metal strip is in the cage area placed aside from the swinging area of the contact spring and the control shaft has two adjoining cams for forcible moving of this contact spring in all the four switch positions, out of which earns a half-circle-shaped one controls one part of the cage, whereas a drop-formed, immediately adjoining cam, by and large perpendicular in relation to the direct section of the former cam, controls the other part of the cage.
  • FIG. 3 shows a section of the body with a view of the blocking device of the control shaft, functioning as the ground conductor
  • FIGS. 4 to 9 show the plug inserted into the opening of the current supply rail with the control shaft still in the position, and more specifically,
  • FIG. 4 shows the ground conductor in its retracted position eliminating the blocking of the control shaft
  • FIGS. 10 and 11 show the two fastening springs of FIG. 2 alone
  • FIG. 14 shows a vertical section of FIG. 12 through the double-acting contact spring
  • FIG. 20 gives a perspective view of a component of the control shaft in the control area of FIGS. 16 to 19;
  • FIGS. 21 and 22 show two views of this spring alone at angles differing from each other by 90.
  • the U- or H-shaped current supply rail, 1 consists of metal or plastic material.
  • a bare ground conductor E In each of the side webs, there are on strips of insulating material the bare conductors R, S, T, Mp (FIG. 4).
  • a turnable control shaft 3 of insulating material is fitted to the walls of the plug body 2 that run transverse in relation to the longitudinal direction of the rail 1. At one end of the shaft there is a turning handle 3 (FIG. 1). This shaft 3 serves for the controlling of the four flat contact springs 6 FIGS.
  • the metallic bar 4 functioning as the ground conductor, has an extension 4 in the middle with a hole 4 for the passing through of the control shaft 3, which is under tension of a compression spring 4 Moreover, in the hole 4* there is a groove recess 4 so that the compression spring 4 can operate only if the control shaft 3 is in the 0 position, i.e. a projecting part 3' permits the operation.
  • the blocking of the control shaft 3 is automatically relieved when the plug 2 is inserted into the opening of the current rail 1 as soon as the advanced free end 4 of the bar 4 reaches the ground conductor E.
  • the end 4 of the bar 4 meets an empty space in a longitudinal groove 1 in the bottom of the current rail 1 so that the blocking 4 3 is not relieved and therefore turning of the control shaft 3, 3 remains excluded.
  • a projecting part 2 at the end matches the bottom groove 1 and guarantees an uninterchangeable insertion of the plug to the correct depth.
  • the guide surfaces 3, one displaced axially from the other, of the control shaft affects the fastening springs 5, also in the same way arranged one adjacent the other, so that they press the springs outwards whereby their ends 5 bent outwardly catch behind the attachments 1 directed inwardly, of the current rail 1.
  • the blocking device for the plug 2 remains in operation in any of the three switch positions R, S, T because the fastening springs 5 are supported by the round guide surface 3 covering about 270 of the circular periphery of the control shaft 3.
  • Both of the guide surfaces 33 of the control shaft 3 are arranged so that their angle difference is about 180.
  • Both of the fastening springs 5 and 5 (FIGS. 2, 10 and 11) are in their central area 5 cut to about one half of their width in order to reduce the construction length of the control shaft 3.
  • the fiat contact springs 6 for the four conductors Mp, R, S, T are controled by the corresponding guide surfaces 3, 3 3 3 3 3 3 3 of the control shaft 3, 3 Springs 6 are designed in such a way that due to material type and strength, they press themselves against the corresponding conductors Mp, R, S, T to such an extent that the current conductivity is insured. Thus, they are subjected to corresponding pre-stress.
  • the breaking of the current connection when the plug is switched off by means of the control shaft 3, 3* takes place in any case through the cam control of the control shaft 3 and 3 which cams lift the springs off the conductors.
  • the contact spring 6 for the conductor Mp due to design of the guide surface 3", 3 of the control shaft 3 at this point, remains switched-on in all the switch positions R, S, T.
  • the contact springs 6 (R) in FIG. 7, 6 (S) in FIG. 8 and 6 (T) in 'FIG. 9 are pressed in only one of the corresponding three on positions R, S, T (FIG. 1) against the corresponding conductors R or S or T when the positions of the guide surfaces 3 3 3 with angle difference between each of them, allow this.
  • the body 2 contains the control shaft 3 with its different cams and bears outside an adjusting handle 3* for the adjustment of 4 switch positions, 0, I, II, III.
  • the contact spring serving for alternative touching of the two conductors R, T with its bent contact ends 16 and 26' consists of two spring strips 16 and 26, which form in the middle, by means of corresponding bent portions 16 26, a cage that surrounds tightly a symmetrically even, triangular cam 3 of the control shaft 3.
  • the two contact springs 16, 26 constitute here a constructional unit firmly bound together by means of rivets 7 at both sides of the cage sides 16 and 26.
  • the side faces of this triangular cam 3 are also bowed outwards.
  • the contact springs 16 and 26 are at their lower end fastened to a strip 8.
  • the construction length of the body 2 can be shortened by one spring width. What is obtained is that neither contact spring 16 or 26 can in any position of the switch handle adjust itself automatically.
  • the conductor R or T with good contact touch or it remains exactly in mid-position so that a hinderfree insertion into the current supply rail or removal from the same is insured in the position.
  • the contact spring 36 for touching the conductor S has only one contact end 36' 'bent towards this conductor but here as well the contact spring is bent outwards in the area of the passing control shaft 3 in order to form a cage in the area 36, while there is a similar, essentially shorter, handle-shaped spring part 36 and 36 fastened at both ends firmly with part 36 by riveting or equivalent means.
  • the latter spring part is, however, in the central area moved aside in relation to the longer contact spring 36 and 36' (FIGS. 12 and 22). This moving aside has been produced here, because this contact spring is aifected by two immediately adjoining guide cams (FIG. 20) of the control shaft 3 of different shapes, one of which cams including parts 3 and 3 is generally semi-circular.
  • the other guide cam 3 has a drop-shaped section, the line of symmetry of which runs about perpendicularly in relation to the direct fiat surface 3 of the adjoining guide cam. This causes the position of the contact spring 36, to remain in the switch positions 0, I and III always in the midle area although, due to turning of the control shaft 3, it eventually touches the two guide surfaces by different sections, only in position 11 is the contact spring 36 pressed olf from this mid-position to the left against the conductor S.
  • a connecting plug which can be inserted into the 8 opening of an essentially U-shaped current supply rail including side walls and at least three bare conductors and at least one bare ground conductor on said side walls, said plug including contact springs and fastening springs and, in relation to the current supply rail, a longitudinally disposed control shaft having guide surfaces and which displaces the contact springs against the conductors and the fastening springs into recessed spaces provided in the current supply rail by means of said guide surfaces, said control shaft having operative and inoperative positions, the guide surfaces of the control shaft being positioned angularly with respect to each other so that the contact springs actuated by the corresponding of said guide surfaces are selectively displaced in at least two contact positions with the corresponding conductors when the control shaft is turned from said inoperative position, said plug further including a bar-like spring biased movable element for obtaining advanced contact with the ground conductor of the current supply rail upon insertion of the plug into the latter, the barlike element preventing the turning of the control shaft from its inoperative position.
  • Plug according to claim 1 comprising a spring and wherein the bar-like element includes a central extension for the control shaft provided with an elongated hole with a blocking recess so that the control shaft which includes a co-operating projecting part can engage the recess in the inoperative position under the action of said spring.
  • a connecting plug which can be inserted into the opening of an essentially U-shaped current supply rail including side walls and at least three bare conductors and at least one bare ground conductor on said side walls, said plug including contact springs and fastening springs and, in relation to the current supply rail, a longitudinally disposed control shaft having guide surfaces and which displaces the contact springs against the conductors and the fastening springs into recessed spaces provided in the current supply rail by means of said guide surfaces, said control shaft having operative and inoperative positions, the guide surfaces of the control shaft being positioned angularly with respect to each other so that the contact springs actuated by the corresponding of said guide surfaces are selectively displaced in at least two contact positions with the corresponding conductors when the control shaft is turned from said inoperative position, said plug further comprising two hook like fastening springs for locking the plug in the current supply rail and arranged on opposite sides of the control shaft and, directed outwards, each fastening spring being blockable by means of a guide surface on the control shaft into
