    • H01R41/00—Non-rotary current collectors for maintaining contact between moving and stationary parts of an electric circuit

Definitions

  • the invention relates to a conductor line with a rail housing that is at least partially open at the bottom, in which a current collector trolley mounted on rollers, which contacts several conductors running in the interior of the rail housing via several sliding contacts, is guided in a longitudinally displaceable manner, the underside of the rail housing being guided in the longitudinal direction by means of a of the rail housing extending, elastically deformable lip pair is closable and the carriage comprises a receiving part extending downwards between the lips out of the rail housing.
  • Such conductor lines are used in particular in industry and are arranged in the ceiling area in order to be able to supply power to mobile, power-consuming units regardless of location, without the power supply interfering with the operating sequence.
  • the side of the rail housing which is open at the bottom is It can be closed by means of lips which are inclined downwards, run obliquely towards one another and are pressed apart laterally essentially downwards by the cable receiving part. Adequate security, in particular against sparks falling out in the area of the cable receiving part, is however not guaranteed. Furthermore, there is a strong abrasion of the rubber material of the lips on the lips, particularly in the area of line curves, which on the one hand worsens or even removes the seal of the lips and on the other hand creates abrasion material which can be disruptive in the production process taking place below the conductor line.
  • the invention is therefore primarily based on the object of improving the known conductor line so that it meets higher safety requirements.
  • this object is essentially achieved in that the lips of the pair of lips are arranged essentially parallel in their starting position and that the cable receiving part penetrates the gap defined between the two lips at an angle of less than 90 degrees, measured to the plane of the pair of lips in the starting position.
  • this angle can be less than 45 degrees. It is particularly preferred if the angle is selected such that the free ends of the lips in the region of the receiving part run essentially parallel, preferably in opposite directions, parallel to the receiving part.
  • the construction according to the invention has several advantages.
  • the essentially parallel arrangement of the lips, with the lips in their starting position Position lie essentially in the same plane that the lips rest flat against one another in their starting position, in which they preferably overlap one another, whereby a particularly secure seal is created, in particular in comparison to the linear contact of the sealing lips according to the prior art .
  • the cable receiving part does not run out vertically downwards from the rail housing, as in the prior art, but rather, according to the invention, runs out obliquely to the side, the inclination of the outgoing cable receiving part being close to the horizontal, the two lips in the outlet area of the cable receiving part become only relative slightly, namely by half the thickness of the cable receiving part, deflected.
  • this has the advantage that the lip material has to be subjected to little stress, lower opening forces occur, lower frictional forces occur, so that the abrasion of the lip material is reduced, and the memory capacity of the lip material is not negatively influenced due to the relatively low stress even after long operation becomes.
  • the measures described above ensure a secure seal between the side surfaces of the cable receiving part and the sealing lips, arises in the area and behind the cable receiving part between the opening or closing lips, an approximately wedge-shaped gap which widens towards the cable receiving part and through which sparks could still escape from the inside of the rail housing to the outside.
  • the cable receiving part in the area in which it penetrates the lips is formed approximately wedge-shaped at its front and rear ends seen in the running direction of the carriage is that it essentially closes the approximately wedge-shaped gap space which arises in front of and behind the cable receiving part between the two lips.
  • the cable receiving part is formed by two parallel plates, in particular metal sheets, spaced transversely to the running direction, wedge pieces are provided in the region of the wedge-shaped design of the cable receiving part, which simultaneously form spacers for the plates.
  • the rail housing has two lower, mutually facing wall sections running in the longitudinal direction of the rail housing, which define a gap between them for the cable receiving part
  • the gap width defined between these lower wall sections is not must be larger than 10 mm to ensure that you cannot reach into the inside of the rail housing with your finger on the live conductors. Due to this maximum gap width of 10 mm, there is an inevitable requirement for a correspondingly narrow configuration of the cable receiving part extending through the gap, which is a certain requirement represents constructive limitation.
  • such a known construction does not exclude the risk of being able to come to the current-carrying conductors with an object such as a bent wire or the like.
  • Such a construction has the advantage that the width of the gap defined between the two inner wall sections is no longer limited to 10 mm, but can be wider after a finger inserted between the two inner wall sections can no longer be bent and therefore no longer closed the current-carrying conductors arranged regularly in the region of the side walls of the rail housing can reach.
  • the increased gap width between the inner wall sections enables a correspondingly larger width of the cable receiving part or correspondingly larger tolerances. If the inner wall sections are raised sufficiently far up to the vicinity of the upper wall of the rail housing and the distance between the inner wall sections and the current-carrying conductors is greater than the diameter of the gap defined between the inner wall sections, it is also no longer possible to use a bent wire or the like. to contact the live conductors.
  • the measure according to the invention of the additional, upwardly drawn inner wall sections therefore provides a very effective protection against accidental contact in a simple manner cher, without having to maintain the gap width of 10 mm required in the prior art.
  • the construction according to the invention is also adequately secured against the ingress of splash water or pressurized water. If the inner wall sections are raised sufficiently far upwards, it can be assumed that penetrating pressurized water, such as a sharp water jet or the like, is distributed in the longitudinal direction of the conductor rail before it reaches the height of the upper edges of the inner wall sections, so that it is in the between the inner wall sections and the outer walls of the rail housing defined space, which receives the active line parts, does not even come.
  • pressurized water such as a sharp water jet or the like
  • the rollers of the pantograph carriage run on the two lower wall sections of the rail housing.
  • the present invention provides that one rail is formed on the side walls of the rail housing for the rollers of the carriage, which is arranged above the lower wall sections of the rail housing; in particular, in a preferred development of the invention, the rail is arranged at such a height that only comparatively little play remains between the roller running on it or its flange and the upper wall of the rail housing.
  • Such a construction has the advantage that the side walls of the rail housing are pushed apart to a lesser extent than in the prior art by the weight of the carriage after the corresponding lever arms are shorter. Secondly, a defined play arises between the rollers of the carriage and the inside of the upper wall of the rail housing, which prevents excessive lifting, tilting or tilting of the pantograph carriage relative to the rail housing.
  • the reference number 2 denotes a conductor line, which comprises a rail housing 4, for example made of hard PVC, and a pantograph trolley which is guided therein and is designated overall by the reference number 6.
  • the conductor rail can be fastened or suspended from a ceiling in a known manner by means of metal clips, not shown, which encompass the lower ends of the side walls 8, 10 of the rail housing and which are provided at regular intervals along the conductor line 2.
  • various brackets 14 are formed on the side walls 8, 10 and on the upper wall 12, which are used to hold various current-carrying lines in the form of copper strips; in the case of the exemplary embodiment described here, the neutral conductor 16 is arranged on the left side wall at the bottom, an active conductor 18 at the top, an active conductor 20 and 22 on the right side wall at the top and bottom, and a protective conductor 24 on the upper wall 12. If necessary, additional active conductors can be pulled into suitable holders 14 in the middle of the left and right side walls.
  • rollers 26, 28 are formed, which extend horizontally in the longitudinal direction of the conductor line and serve as rails for the rollers 26 of the carriage 6.
  • the carriage 6 has four such rollers 26, namely two on each side and two arranged one behind the other perpendicular to the plane of the drawing.
  • the rollers 26 are dimensioned such that between the wheel flange of each roller 26 and the underside of the upper wall 12 there is a relatively small distance of about 1 to 2 mm, which for a defined game against lifting, tipping or tilting of the carriage relative to the rail housing 4 cares.
  • a lower wall section 36, 38 extending in the horizontal direction is provided on each side wall, the wall sections 36, 38 lying opposite one another, forming a gap running in the longitudinal direction of the conductor line.
  • an inner wall section 40, 42 On the longitudinal edges of the two lower wall sections 36, 38 facing the gap is followed by an inner wall section 40, 42, each of which extends vertically upwards into the vicinity of the upper wall 12 of the rail housing 4.
  • the distance defined between the two inner wall sections 40, 42 is smaller than the distance of the inner wall sections from the side wall 8 or 10 facing the respective wall section or from the current-carrying copper strip conductors 16 to 22 arranged there.
  • two substantially horizontally extending elastically deformable lips 44, 46 are arranged, which are suitably fixed, for example locked, to the rail housing 4 at their outer ends facing the side walls 8 and 10, respectively, and which are locked in their Initial state, which is indicated in FIG. 1 by the dashed lines, overlap, the lips 44, 46 sealingly abutting one another in the overlap region, so that the interior of the rail housing is sealed off by the lips 44, 46.
  • the carriage 6 comprises two halves which are essentially symmetrical in the area of the rail housing 4, each of which has a multi-angled sheet metal part as a supporting part, which in addition to the associated rollers 26 also carries the respective sliding contact parts.
  • the angled sheet metal parts are provided with the reference numbers 32 and 34 in FIG.
  • Each sheet metal part 32, 34 comprises a central section 48, 50, the central sections 48, 50 lying parallel to one another within the space formed between the inner wall sections 40, 42 and by means of suitable spacers, not shown, made of art fabric are attached to each other. These spacers are preferably provided on the front and rear end regions of the middle sections 48, 50, so that a through-channel for receiving cables is formed between the middle sections 48, 50 and the spacers.
  • a further, horizontal, upward-pointing section 60 or 62 can connect to the outer section 56 or 58, these sections 60, 62 carrying the resilient sliding contact elements 64, 66 or 68, 70 in the suitable position, whereby these sliding contact elements are in electrical contact with the corresponding current-carrying conductors 16 to 22.
  • Another contact element 72 for example in the form of a spring plate, is fastened to the upper sections 52, 54 of the plate parts 32, 34 and is in sliding contact with the protective conductor 24.
  • a cable receiving part Connected to the central sections 48, 50 is a cable receiving part, designated overall by reference numeral 74, which projects downward from the space formed by the inner wall sections 40, 42 and opens into a cable box 76 rigidly connected to it.
  • the cable receiving part 74 is also essentially formed by the sheet metal parts 32, 34 and is curved in the manner shown in FIG. 1. In particular, in the area of the lips 44, 46 it is designed to be inclined at an acute angle to the horizontal, so that it penetrates the sealing lips or the gap formed by the sealing lips at an acute angle.
  • the sealing lips of the cable receiving part 74 are opened to a comparatively small extent and at the same time only slight frictional forces occur, while on the other hand outside the area of the cable receiving part 74 the sealing lips can lie against one another in an overlapping manner.
  • the inclination of the cable receiving part 74 is selected such that the lips 44, 46 lie flat against the respective outer sides of the cable receiving part 74, as a result of which a particularly good seal is achieved even in the area of the cable receiving part.
  • the angle which the cable receiving part 64 forms in the region of the lips 44, 46 with the horizontal or with the plane of the lips is approximately 14 degrees.
  • the optimum angle in each case depends, among other things, on the thickness of the cable receiving part and the flexibility of the lips.
  • the lips are arranged asymmetrically with respect to the vertical center plane of the conductor line 2, in particular the overlapping area of the lips is offset to the left, so that the cable receiving part 74 can be effortlessly positioned between the top left and bottom right Can slide lip.
  • the right, lower lip 46 can for example be longer than the left lip 44, or the attachment of the right lip is shifted to the left with the same width of the lips.
  • FIG. 2 shows a cross section through the cable receiving part 74 in the region of the lips 44, 46.
  • the side walls 78, 80 of the cable receiving part 74 are formed by integral lower sections of the sheet metal parts 32, 34 and the central sections 48, 50. These lower sections 78, 80 are seen in the direction of travel of the car at the front and rear with spacers 82, 84 made of plastic, which on the one hand keep the sections 78, 80 at a distance and fix them to one another and on the other hand wedge-shaped, tapering towards the front and back trained sections, which serve to seal the lips between the closed lips and the open in the area of the cable receiving part 74 in front of and behind the cable receiving part, also in an approximately wedge-shaped space, so that the best possible seal of the conductor line downwards even in the area of Cable receiving part is guaranteed.
  • Reference number 86 denotes the cavity defined by the cable receiving part 74 for receiving the cables running between the sliding contact elements 64 to 72 and the cable box 76.
