Definitions

  • the present invention relates to a multiple terminal block for its arrangement on parallel vertical supports of low-voltage distribution systems.
  • Multiple terminal strips of the aforementioned type are usually numerous and in close arrangement on the vertical supports of the frame systems of telephone systems and. Like. And serve the connection of the incoming and outgoing conductor.
  • connection strips arranged on the frame to which a large number, usually lead to bundles of wires, which remove or. Difficult to reassemble the terminal strips and which must be installed with large reserves in order to be able to achieve a sufficiently large working distance with the terminal strips when they are used for changes, additions, checks and the like.
  • the connection strips are removed from the frame, pulled far forward while stretching the wire bundle and rotated about their longitudinal axis in order to bring the rear connection means forward and to make them accessible.
  • the wire bundles and individual conductors are exposed to uncontrolled movements and loads and assume undefined positions, in particular when resetting the relevant terminal strips, which has a negative effect on the connection points.
  • the object of the invention is now to design the multiple terminal strips for their arrangement on parallel vertical supports of low-voltage distribution systems in such a way that they can be easily moved between the mounting position and the easily accessible manipulation position without significant stress on the conductors and their connection points.
  • Such a terminal strip which is quasi suspended from the wire bundles, can be easily rotated around the wire bundles that act as axes of rotation, for example, pulled forward from the distribution frame, the wire bundles freely moving in the wire trapping space, so that only the inlet bend of the wire bundles opens or opens somewhat in the wire trapping space closes what is completely uncritical if the arc radius is large enough.
  • a preferred embodiment of such a terminal strip can then be seen in that tabs flanged on each end face delimit the wire catching space as an outer side wall, the tabs then delimiting a threading slot for the conductors between them.
  • the inner side walls of the wire trapping spaces formed on the end face of the terminal strip are at least partially elastic tongues that interact with recesses in the vertical supports of the distributor certain pawls, the terminal strips can be snap-fitted or be dismantled.
  • Fig. 1 shows a vertical support 10 with side boards 11 and 11 'of a frame of a low-voltage distribution system, not shown, in particular telephone system, to which vertical support 10 a plurality of multiple terminal strips 1 are arranged one above the other, in a known manner incoming and outgoing conductors 3 with each other connect to.
  • connection strips 1 in order to easily connect them between the mounting position shown in FIG. 1a and an easily accessible one shown in FIG. Fig. 1c manipulation position to be able to move without noticeably stressing the conductor 3 and their connection points on the terminal strips.
  • each end face of a terminal block 1 has an adjoining wire trap space 2, which leads the conductors 3 and. a wire bundle 3 'is used, this wire catcher 2 forms a fulcrum for the rotatable in its longitudinal extension terminal block 1 and the wire bundle 3' in the wire catcher 2 acts as an axis of rotation.
  • the terminal block 1 is first detached from the vertical support 10 (FIG. 1a), then pulled forward (FIG. 1b) and then rotated to the rear connections of the terminal block or. to make the overvoltage protection cassette 12 accessible.
  • the wire bundle 3 ' moves freely in the wire catcher 2, so that only the inlet bend 3 ⁇ of the wire bundle 3' opens or closes something, which does not affect the conductors with a sufficiently large arc radius connections affects.
  • the wire trap space 2 is delimited here on the end face of the terminal block 1 by an inner side wall 6 and by an outer side wall 4, 4 ', the latter by flanged or. molded tabs is formed. These tabs 4 and 4 ' also limit a threading slot 5 for the conductor 3rd
  • each inner side wall 6 on the terminal strip 1 forms an elastic tongue which can be pushed away by hand and which is designed to interact with recesses 8 in the side plates 11 and 11, respectively.
  • 11 'of the vertical support 10 certain pawl 7 carries.
