Definitions

  • the first terminal box must be made of a copper alloy; Due to the design of the clamp, a relatively large amount of material (copper) is required.
  • the object of the invention is to provide a terminal of the type mentioned, which is low in material and easy to manufacture and assemble.
  • connection terminal is produced by the method according to claim 4.
  • both terminal boxes can be manufactured independently of one another and combined with one another; it is then only necessary to push the second terminal box over the lower crosspiece of the first terminal box and the Insert clamping screw. Then the terminal support attached or molded onto the arc guide rail is inserted, whereby the first terminal box is supplemented to form the closed frame. If the first terminal box is firmly connected to the arc guide rail, for example by welding, the connection terminal is completed and the method of operation and operation can be used in exactly the same way as the connection terminals according to the above-mentioned documents.
  • FIG. 1 shows a commercially available circuit breaker 10.
  • a switch lock 12 including an electromagnetic release 13 and underneath this an arc extinguishing chamber 14 with arc extinguishing plates.
  • a bimetallic metal 15 which acts on the switching lock 12 via an intermediate member 16 to unlatch it.
  • a movable or rotatable contact lever 17 which is rotatably supported at point 18.
  • the electromagnetic trigger 13 has an impact armature 21, with which the movable contact lever is opened when a short circuit occurs. It also has an extension 22 protruding to the right from the electromagnetic trigger 13, with which it acts on the switching mechanism 12 via a lever linkage 23.
  • the switching lock 12 acts on the movable contact lever 17 to open it via a further intermediate lever 24.
  • the arc quenching plate packet 14 is bounded at the bottom by an arc guide rail 25, which is bent essentially in an L-shape and to whose other leg a connecting terminal 26 is fastened.
  • This connecting terminal 26 corresponds to the arrangement according to FIG. 5, so that the configuration of the connecting terminal 26 can be illustrated with reference to FIG. 5.
  • the connecting terminal 26 has a first terminal box 27 which has a U-shaped first section 28, one leg of which forms the upper crossbar 29 and the other leg of which forms the lower crossbar 31 and in between which there is the perpendicular longitudinal web 30.
  • the lower crosspiece 31 is opposite, as can be seen from FIG. 2 the longitudinal web 30 is formed narrower and has projections 32 on its two longitudinal edges, the function of which is explained in more detail below.
  • a flag 33 is formed which is formed perpendicularly thereto and which, seen in the plane of the upper crosspiece 29, is L-shaped; the leg 34 formed directly on the upper crossbar merges into a leg 35 extending transversely thereto, which is used to fasten connecting leads or connecting lines to further components of the circuit breaker.
  • a bore 3b is located in the upper crosspiece 29.
  • the second terminal box 37 (see FIG. 3) forms a closed frame with a U-shaped area 38; the two ends of the legs are angled towards each other and overlap; they form the upper crosspiece 39 of the second terminal box 37.
  • the legs of the U-shaped area have slots 40 and 41; The projections 32 engage in these slots 40 and 41 in order to guide the second terminal box 37 against rotation relative to the first terminal box.
  • the upper crossbar 39 has a threaded bore 42.
  • FIG. 4 shows the arc guide rail 25. It serves, with the area 43 drawn at the bottom in FIG. 4, as the lower limit of the arc-quenching plate package 14 (see FIG. 1) and is therefore at this point parallel to the bottom of the housing 11 of the circuit breaker 10 in the housing 11 inserted.
  • the area 44 running perpendicularly to this has a U-shaped bend 45, the length L of the leg of the bend 45 of the height H or the distance H of the upper from corresponds to the lower cross piece 29/31 of the first terminal box. It can be seen in FIG. 5 that in the assembled state the leg of the bend 45 fits exactly between the upper crosspiece 29 and the lower crosspiece 31.
  • the bend 45 thus complements the U-shaped section '20 to form the complete first terminal box or box frame, the bend 45 forming the inner longitudinal web of the first terminal box.
  • the legs that is to say the upper and lower transverse webs 29, 31, can be supported on the bend 45 when a line or the like is clamped in.
  • the arc guide rail 25 has an extension 47 which extends beyond the outer surface of the web 4b of the U-shaped bend 45 and which is struck against the formation 33 or against the leg 34 of the formation (see FIG. 5), both of which are fixed by means of a welded connection 48 are interconnected.
  • connection terminal is then manufactured as follows:
  • the arc guide rail forms a unit with the connection terminal or supplements the arc guide rail to form a finished box terminal.
  • a clamping screw 49 is screwed into the threaded bore 42, the clamping screw 49 passing through the bore 36 in the upper crosspiece.
  • the bend 45 is now used to support the upper compared to the lower crossbar 29 or 31 when clamping connection conductors either between the lower crossbar and the second box terminal (conductor connection I) or between the terminal screw head and the upper crossbar (conductor connection II).
