Definitions

  • the invention relates to a clamp according to the preamble of claim 1.
  • Such terminals are used for electrical switching devices, in particular for circuit breakers or residual current circuit breakers, to connect round conductors or rails to the switching device.
  • the terminals have to be made relatively large due to the required conductor cross-section and accordingly regulations existed in older regulations, according to which a certain terminal size, a certain thread diameter and a certain thread length was assigned.
  • the new international regulations do not include these requirements. This results in the possibility of dimensioning the connecting terminals, and in particular the terminal frames, more economically and with smaller outer dimensions.
  • a connecting terminal has become known, see FR-PS 2 611 911, which has a terminal frame, one crosspiece of which has a connecting piece which surrounds a threaded hole, whereas the other, opposite crosspiece is formed by extensions on the side pieces in that these extensions overlap and are each fixed on the opposite side bridge.
  • the inner crossbar section of the two overlaps, which is connected to the one longitudinal web, is inserted in a recess on the other longitudinal web with a projection and fixed therein, for example caulked, while the outer crossbar section has a T-shaped extension, which in a corresponding recess is bent into the adjacent longitudinal web.
  • clamp frames are relatively expensive to manufacture because of the extensions and recesses to be formed and these extensions have to be bent into the recesses on the adjacent side web. It is therefore an object of the invention to provide a clamp of the type mentioned in the introduction, in which the clamp frame can be manufactured simply and in a space-saving manner.
  • the first crossbar can then have a socket formed on the outside, which surrounds the threaded bore.
  • the cross bar is formed only by the extension of the associated side bar; There are no overlaps.
  • this terminal frame is designed according to the invention in accordance with the characterizing features of claim 3.
  • the two superimposed crossbar sections are held in the area of this side web, whereas the crossbar section, which is located inside the terminal frame, is caulked in the longitudinal web, in the recess of which it engages.
  • the two crossbar sections can each be held in the region of the longitudinal webs, so that an optimal and inexpensive crossbar guidance and crossbar fixing is ensured.
  • the extensions which comprise the outer crossbar section, can be bent towards one another, so that an improvement in the mounting and fixing is ensured.
  • a terminal frame which is part of a terminal described, for example, in P 31 37 117.5-34, has a first longitudinal web 10 and a second longitudinal web 11, both of which are assigned in parallel to one another.
  • the two longitudinal webs 10, 11 are interconnected at one end by means of a first crossbar 12 and at the opposite end by means of a second crossbar 13 supplemented or connected to a terminal frame.
  • the first cross bar 12 located at the top of the drawing, has a connecting piece 14 which, on the surface of the cross bar 12 opposite the cross bar 13, projects beyond it and surrounds a threaded bore 15 into which a clamping screw, not shown, can be screwed.
  • the longitudinal web 11 is elongated in relation to the longitudinal web 10 and projects with a longitudinal web section 16 above the upper transverse web 12.
  • a recess 17 is made, into which a projection 18 of the transverse web 12 is inserted or inserted and by force acting in the direction of arrow P is caulked and fixed in the recess 17.
  • a clamp frame is created that is easy to manufacture and has a sufficiently high strength.
  • the clamp frame according to FIG. 3 has a first cross piece 30, opposite which a second cross piece 31 is located, which two cross pieces 30 and 31 are connected by means of longitudinal pieces 32 and 33.
  • An upper or outer crossbar section 34 is formed on the longitudinal web 32, whereas a lower or inner crossbar section 35 is arranged or formed on the longitudinal web 33, which overlap one another in the assembled state and thus form the first crossbar 30.
  • the upper crossbar section 34 is bent inwards, that is to say perpendicularly to the longitudinal web 32, and it has a projection 36, the length of which - as an extension of the longitudinal extent of the crossbar section 34 - corresponds approximately to the thickness of the sheet metal strip which the terminal frame is made of.
  • the lower transverse web section 35 is bent out of the longitudinal web 33 as a tongue, the width B of the tongue being narrower than the total width b of the terminal frame.
  • the longitudinal web 32 there is an opening 37, into which the tongue 35 or the lower transverse web section 35 engages and is caulked therein by plastic deformation, namely here by pressing in the direction of arrow P1.
  • the tongue 35 widens in this area, so that the side edges lie against the inner edges of the recess 37. So that the application of the force P 1 is possible, the opening 37 is open at the top, that is in the direction of the longitudinal webs 32, 33.
  • extensions 38 and 39 remain which are brought into an L-shape and comprise the projection 36, so that the projection 36 and thus the outer transverse web portion 34 are in the shape of the L-shape and the bow of the tongue 35 formed half opening 40 is held.
  • extensions 38 and 39 which are designed as straight extensions, can simply be bent inwards so that they form an acute angle with one another as extensions 41 and 42.
  • FIG. 6 shows the embodiment according to FIGS. 3 and 4 in the direction of arrow VI.
  • the extensions 38 and 39 since they form an L-shape, cover the upper crossbar section 34 and the projection 36 of the upper crossbar section 34, respectively.
