Definitions

  • the invention relates to a screw connection terminal provided, in particular, for an electrical switching device which can be lined up with identical or similar devices and which consists of a clamping screw, an essentially frame-like clamping part receiving the clamping screw in a threaded opening and a frame part joined to the clamping part, and which is used for contacting the connection tab of a busbar, and - in a separate insertion area - can also be used to connect the line end of a further connection line.
  • Screw terminals are used in a wide variety of configurations, including electrical switching and installation devices, and are used to connect electrical conductors, which in turn are used for Power supply for electrical consumers.
  • the electrical conductors which can be designed as simple wires or strands, but also as strands provided with cable lugs or also as busbars, are mechanically fixed by the interaction of two clamping elements.
  • a screw terminal has a clamping element firmly anchored in the device with a threaded opening, into which a clamping screw is screwed. The conductor to be connected is now clamped between this clamping screw and said clamping part.
  • a screw connection terminal consisting of a box frame, a terminal frame and a clamping screw has become known, which is incidentally additionally equipped with a compression spring.
  • Box frame and terminal frame of this screw connection terminal interlock and form a receiving space for the conductors to be connected between two adjacent frame legs.
  • the clamping screw By means of the clamping screw, the box frame and the terminal frame are pressed against each other - against the force of the spring element, whereby the two frame legs mentioned, between which the conductors to be connected are located, to be pressed together.
  • This screw terminal provides certain advantages, namely first by providing a relatively large cross-sectional space for conductors to be connected, in addition, one or more conductors inserted into the screw terminal are held to a certain extent immediately after the insertion process, for which the spring element mentioned is used. It is disadvantageous that this screw terminal takes up a comparatively large amount of space in the direction of the axis of the clamping screw; in addition, the clamping force with which the conductors are clamped is determined by the spring elements or the clamping screw must be screwed in until the turns of a spring element designed as a compression spring lie on one another. A disadvantage of this screw terminal is that the connection of two or more conductor elements is very critical if these conductor elements have different cross sections.
  • this known terminal has the advantage that it can accommodate two or more electrical conductors, which can have completely different cross sections, for example a busbar and a conductor with a round cross section. This is achieved by two different connection points, namely one directly below the screw head of the clamping screw and another connection point between two frame legs, on the lower one, facing away from the clamping screw End of the screw connection clamp.
  • a screw terminal of the last-mentioned embodiment which avoids the cost disadvantage of an additional spring member, can be found in DE-OS 31 37 117, here from FIGS. 4 to 6.
  • a busbar to be connected below the head of the clamping screw must either be provided with a through-hole (according to FIG. 4 of this publication) or instead with a corresponding fork.
  • the present invention has for its object to provide an inexpensive screw connection terminal which has two separate receiving areas for conductors to be connected, which are not penetrated by a screw shank, so that, for example, a busbar to be accommodated, itself then, when it takes up almost the entire width of the associated receiving opening, it does not have to be provided with a hole or with a fork. Both or all of the conductors to be connected should be firmly clamped at the same time by means of one and the same clamping screw.
  • Such a screw connection terminal accepts the presence of an additional pressure piece, but a spring element is omitted, as is often provided in other known screw connection terminals.
  • this screw connection clamp has the additional advantage of even offering a third connection point in particularly stored cases, namely below the head of the clamping screw or between the two legs of the pressure piece and the clamping part directed towards the clamping screw head.
  • this screw terminal offers the advantage that the parts to be clamped together by means of the clamping screw are pulled towards one another during the clamping process instead of moving from one another, as is the case with some known terminal clamps.
  • An expedient embodiment of a screw connection clamp the clamp part of which is designed as a U-shaped frame that is open on one side, can be achieved in that the central limb of the clamp part runs parallel to the screw axis of the clamp screw and is equipped with at least one stiffening which increases its resilience to bending, in particular one in the form a bead running in the longitudinal direction of the middle leg or an outward, narrow bevel.
  • a similar, advantageous embodiment relates to a screw terminal, whose pressure piece combined with the clamping screw is U-shaped is, for which it is proposed, to equip the middle leg of the pressure piece, which runs parallel to the screw axis of the clamping screw, with at least one stiffening which increases its resilience to bending, also here in particular in the form of a bead running in the longitudinal direction of the middle leg or an outwardly directed, narrow one Folding.
  • the contact pressure when tightening the clamping screw can be increased without running the risk that the U-shaped parts are permanently deformed.
  • the design of the clamp part or the pressure piece as a U-shaped part has the advantage of a slightly lower material requirement and a much easier assembly and, depending on the design of the device receiving the screw connections, also offers the possibility of being able to replace one of the parts without To have to bend a frame-shaped part.
  • FIG. 1 illustrates the side view of an electrical switching device in the form of a circuit breaker 10.
  • a circuit breaker 10 of this type - which cannot be seen from this illustration - can be fastened on a hat-shaped mounting rail and can be lined up with the same or similar devices with the same fastening option.
  • the right side of the circuit breaker 10 in the illustration represents the current access side. This current access area is shown partly broken away, as a result of which a screw terminal 11 is visible.
  • a busbar package 12 with terminal lugs 13 extending therefrom and - lying above - the partially stripped line end of a further connection line 14 can be seen.
  • FIG. 2 illustrates the screw terminal 11 already recognizable in Figure 1, which is composed of a clamping screw 15, a frame-like clamping part 16 and a frame part 17 and finally a U-shaped pressure piece 18.
  • the clamping screw 15 penetrates the upper free leg 19 of the pressure piece 18 and is screwed into a threaded opening in the - in the illustration - upper frame leg 20 of the frame-like clamping part 16.
  • the frame-like clamping part 16 accommodates the frame part 17 or surrounds it, at right angles to the frame plane of the frame part 17.
  • the lower, free leg 21 of the pressure piece 18, which is shown in the illustration also projects into the inner frame area of the clamping part 16. In this way, a - based on the illustration - lower connection point 22 for receiving a terminal lug 13 of the busbar assembly 12 and an upper connection point 23 for receiving the line end of the connection line 14 are formed.
  • laterally protruding lugs 26 can be formed on the side of the upper frame leg of the frame part 17, which protrudes into corresponding (not numbered) guide slots in the adjacent frame legs of the frame-like clamp part 16 and in this way tie the frame part 17 and the frame-like clamp part 16 together.
  • FIG. 3 A front view of the screw terminal according to FIG. 2 is illustrated in FIG . 3 . Also recognizable here is the clamping screw 15, the frame-like clamping part 16, the frame shape of which can now be better seen from this illustration, and the frame part 17 with its laterally protruding lugs 26. In the two connection points 22 and 23 are - cut, therefore hatched - the cross sections both the terminal lug 13 of the busbar package 12 and the stripped line end of the connecting line 14 can be seen.
  • both the lower connection point 22 and the upper connection point 23 are not restricted in any way, for example by a screw shaft.
  • connection point that is actually only required in exceptional cases could, moreover, be formed between the upper free leg 19 of the pressure piece 18 and the upper frame leg 20 of the clamping part 16, but here there would be a certain constriction through the threaded shaft of the clamping screw 15.
  • FIG. 4 A somewhat different embodiment of a screw connection terminal is illustrated in FIG . 4 .
  • the screw connection terminal shown here and identified by the number 27 also has a clamping screw 28 with a pressure piece 29, the latter, however, being designed as a closed, frame-like part, unlike in the exemplary embodiment explained above.
  • This clamping screw 28 is also screwed into a threaded bore in the upper frame leg 30 of a basically frame-shaped, more precisely a U-shaped clamping part 31 in this embodiment.
  • This clamping part 31 also surrounds a frame part 33, the lower frame leg of which is equipped with a leg extension 34.
  • This leg extension 34 can, as in the previously explained embodiment, serve to fix the frame part 33 within a device receiving the screw terminal 27 and possibly simultaneously as a fixed contact.
  • the described and illustrated assembly of the individual parts of the screw connection terminal 27 in turn forms a lower connection point 35 and an upper connection point 36 for receiving a connecting lug 37 of a busbar package 38 and for separately receiving the line end of a connecting line 39.
  • FIG. 5 shows a front view of the screw connection terminal 27 illustrated in FIG. 4.
  • the clamping screw 28 with the pressure piece 29 can be seen, furthermore the U-shaped clamp part 31 with the stamping or bead 32 in the present case, and finally the frame part 33.
  • the cross sections of the line ends to be supplied to the connection points 35 and 36 of the connection line 39 and the busbar package 38 or its connecting lug 37 are shown hatched.
  • a wall 40 is indicated, which is provided with a recess 41 for the leading reception of the bead 32.
  • the wall 40 is part of an otherwise not indicated switching device, for example a circuit breaker, as shown in FIG. 1 and provided with the number 10.
  • the representation of this wall 40 is intended to illustrate how a lateral displacement of the clamping part 31 together with the clamping screw 28 and its pressure piece 29 is avoided in practice.
  • the screw connection terminals 11 shown (according to FIGS. 1 to 3) and 27 (according to FIGS. 4 and 5) are merely exemplary embodiments of the subject matter of the invention.
  • the representations are not to be considered as true to scale, i. H. the length of the clamping screws, for example, as well as the length and width dimensions of the individual legs or rabbet legs of the clamping parts as well as the frame parts and the pressure pieces must be adapted to the corresponding connection requirements with regard to the conductor cross sections to be accommodated, etc., in such a way that the expected function of the screw connection terminals is fully fulfilled.
