Definitions

  • the invention relates to a strip for a distribution system of conductors, in particular for control, monitoring, data and telecommunications technology, which strip can be snapped longitudinally by means of clips onto one or two adjacent carrier profiles, electrical conductors being both signal-transmitting and perform live functions.
  • the invention further relates to an assembly channel in a distribution system for conductors, which is essentially U-shaped and has a carrier profile on both sides of the longitudinal opening, onto which strips can be snapped.
  • the invention relates to the use of two strips.
  • strip is used to denote connection strips, isolating strips and other connection modules for distribution systems, and the term “conductor” means electrical cables and wires and optical fibers.
  • EP 0133824 describes a terminal block with wire guides, which can be snapped directly onto a carrier profile. Two hook strips, widely spaced apart according to the support profile, protrude from the connection strip, into each of which a profile flag of the cross-sectionally elongated support can be snapped.
  • the support profile is only on one side, but is not attached to it. A shift of the connection strips along the support profile seems possible due to the constructional circumstances. Nevertheless, the swiveling out and the longitudinal displacement have been unsatisfactorily solved.
  • EP 0304 393 B1 discloses a device for holding connection strips of telecommunications technology, which consists of an assembly frame, at least one connection strip arranged thereon and at least one connecting element.
  • the mounting frame is made up of at least one in a frame-mounted profile rail with a circular cross-section.
  • the terminal block as a connecting element has an arcuate snap element that can be snapped onto the profile rail.
  • Both legs of the snap element are resilient and have a contact surface corresponding to the diameter of the profile rail.
  • the diameter of the profile rail must correspond to that of the contact surface of the snap element.
  • the good displaceability along the profile rail has the disadvantage that the strips are not stable in position in the medium and long term, in particular in the event of unavoidable vibrations, ie they slide off.
  • the inventor has set himself the task of creating a strip of the type mentioned at the outset, which can also be snapped onto, and preferably pivoted on, optimally other than circular support profiles. Furthermore, an assembly channel is to be created in a distribution system for conductors of the type also mentioned in the introduction, on which strips can be snapped on without medium and long-term position changes.
  • the object is achieved according to the invention in that the clips of the bar consist of at least two projecting webs, at least one of which is resilient and has a latching lug, the webs not having an arcuate support surface for a carrier profile. Further developing and advantageous embodiments of the bar are the subject of dependent claims.
  • the strip according to the invention preferably forms three functional support points or lines, which always ensure secure mounting of the strip.
  • the support profiles with the bar can always be optimally adapted to the installation conditions, a self-supporting construction is created, the bars can be quickly assembled and used universally.
  • the latching lugs - as is customary in the prior art - can lie one behind the other. However, they are preferably arranged side by side in this viewing direction and symmetrically with respect to the longitudinal center plane of the bar.
  • Two mutually spaced latching noses can thus be formed adjacent to the end face, while only one latching nose is formed on the side further away from the end face of the bar, which, viewed in the longitudinal direction, lies in the space between the two aforementioned latching noses.
  • the opposite solution is of course also possible.
  • the cross-section of the beam profiles may take any expedient shape, 'in addition to at least partially circular, virtually circular and elliptical cross-sections and polygonal cross-sections for the carrier profiles are possible, in particular hexagonal, square, rectangular, triangular and trapezoid-shaped, with the corners also rounded or chamfered can. Appropriately, these are closed or almost closed tube profiles.
  • star-shaped carrier profiles can also be used. For example, with three to twelve or more cantilevered, regularly distributed longitudinal ribs or longitudinal combs, a star-shaped support profile can be formed, which allows pivoting through a certain angle determined by the number of ribs.
  • a carrier profile formed in the cross section as an equilateral triangle and star shaped carrier profiles have, for example, the advantage over the circular cross section that the clips can be unlocked better.
  • strips with clips formed in the region of both end faces these preferably have at least one rigid, that is to say inelastic or non-resilient, inner web and at least one resilient outer web.
  • the mechanical stability of a distribution system equipped with strips is significantly increased, and deformation of the support profiles by the snap-on strips is prevented by the spacer thus formed, also called a calibration unit for the support profiles up to 3 m long in practice.
  • the web adjacent to the end face of the bar or this and the inner web removed from the end face of the bar preferably have a latching lug. It has already been mentioned that several outer and / or inner webs can also be formed. This is once again emphasized here.
  • the neither resilient nor elastic inner rigid web of at least one clip has an extension in the form of a resilient catch that is angled and / or cantilevered in the direction of the outer web. This is usually almost half as long as the web in question and is expediently delimited against the web with a notch to support the resilient effect.
  • a perforation is punched into at least one leg of the mounting channel, adjacent to the carrier profile, into which the catch of the relevant clip of a strip engages and latches.
  • a scale for the position numbering of the strips is preferably attached. In this way, the position of each bar can be localized immediately and the connections can be recorded for control purposes.
  • cutouts can be made in the legs and / or the base of the mounting channel, which extend over more than one grid unit. This makes the assembly channel easier and more accessible.
  • two strips according to the invention are fastened on a suitable base in such a way that a rigid top-hat rail can be locked with the aid of the resilient outer webs.
  • Such installations are used, for example, in switch boxes of domestic installations, where the top-hat rails are installed horizontally.
  • the advantages of the present invention can be briefly summarized as follows:
  • the clips of the strips are designed in such a way that they can be snapped onto all types of carrier profiles in a flexible manner. - Due to the special shape, three support points or lines can be formed and / or the catches can be easily released.
  • a preferred embodiment of the strips with an assembly channel according to the invention guarantees that the strips are absolutely level.

Abstract

L'invention concerne une barre (10) conçue pour un système de distribution de câbles et de conducteurs électriques (22) et/ou de fibres optiques, en particulier pour les techniques de commande, de surveillance, de traitement de données, et de télécommunications. Cette barre (10) peut être encliquetée sur un ou deux profilés de support (18) parallèles adjacents, et déplacée longitudinalement sur le(s) profilé(s) de support à l'aide de pinces (12). La fonction de ces conducteurs électriques (22) est non seulement de transmettre des signaux, mais aussi de conduire le courant. Les pinces (12) de la barre (10) sont constituées d'au moins deux branches chanfreinées (14, 15) dont au moins une est configurée de manière élastique et comporte un élément de contact saillant (16). Les branches (14, 15) comprennent une surface d'appui courbe pour un profilé de support (18). De préférence, la branche rigide interne (15) d'au moins une pince (12) comprend un élément d'accouplement à déclic (36) élastique, incliné ou chanfreiné de préférence en direction de la branche extérieure (14). Les éléments d'accouplement à déclic (30) verrouillés dans un canal de montage (40) ou un bâti de montage empêchent le glissement de la barre (10) encliquetée, dans la direction longitudinale.
