Definitions

• the invention relates to a connecting element for the assembly of single-pole circuit breakers in a shell construction to form a multi-pole protective switching device.
• this driver consists of a coupling element which is inserted between the housings of adjacent single-pole circuit breakers and must be held on them in a precisely movable manner in order to be able to reliably intervene in the associated switching mechanism mechanisms. This type of coupling of several single-pole circuit breakers is in need of improvement from a design and practical point of view.
• the invention is based on the task of making available a connecting element of the type mentioned at the outset which enables simple manual mutual adjustment of the individual circuit breakers including their mechanical coupling and simultaneously contributes to thermal decoupling of the individual trigger systems.
• the connecting element consists of a spacer profile part, on which mutually protruding spacer and centering sleeves for the engagement in existing housing mounting bores of neighboring circuit breakers and a pivotable coupling member as a driver for the triggering mechanism of neighboring circuit breakers.
• the connecting element according to the invention thus enables a precise, reliable and simple without additional Tool-feasible assembly of single-pole circuit breakers on site to make a multi-pole protective switching device available according to the respective need.
• the one-piece formability of the connecting element makes assembly extremely easy, because the connecting element takes into account all adjustment requirements and internal switching transmission processes adjacent single-pole circuit breakers.
• the coupling member is articulated to a frame profile which projects on both sides of the spacer profile part for engaging in existing housing recesses and which limits the pivoting range of the coupling member in the plane of the spacer profile part.
• the frame profile can be either closed or preferably partially open, in particular when a guide profile is preferably formed on the coupling member, through which the coupling member can be guided perpendicularly to the spacing profile during its pivoting movement in order to maintain its orientation.
• the coupling member or the driver enters an arcuate guide slot in the respective housing recesses and is in engagement with the triggering technology of both switches.
• the guide profile itself is preferably formed in the region of the spacer profile part on the coupling member, which is designed like a bolt, for lateral play-based support on opposite housing recess surfaces.
• the profile part has at least three spacing and centering sleeves, between which struts are preferably provided which have compensating arches.
• any tolerance deviations between the housing mounting holes of adjacent circuit breakers can be compensated elastically.
• the number of at least three spacer and centering sleeves ensures one Reliable alignment, whereby a holding function between adjacent circuit breakers can also be achieved via the spacing and centering sleeves if their outside diameter corresponds to the inside diameter of the existing housing mounting holes.
• the spacer profile part can preferably furthermore have integral full-surface sections, at least for the area between phase connection terminals of adjacent switches, in order to ensure a safe separation here and to avoid connection errors.
• At least the struts consist of plastic in the spacer profile part, but in particular the spacer profile part overall consists of plastic. This is associated not only with advantages in terms of one-piece, simple manufacture, but also with regard to handling and thermal and electrical insulation.

• 1 shows a preferred exemplary embodiment of a connecting element 10 for the assembly of single-pole circuit breakers in a shell construction to form a multi-pole protective switching device.
• the connecting element 10 consists of a flat spacer profile part 11 made of plastic, on the front and back of which three spacer and centering sleeves 12, 13 and 14 are integrally formed.
• the spacer and centering sleeves 12, 13 and 14 serve, as indicated in Fig. 2, for the appropriate engagement in existing housing mounting holes 15, 16 and 17, which receive recessed fastening elements when mounting the housing shells of the single-pole circuit breaker.
• a coupling member 18 is integrally formed on the spacer profile part 11 as a driver for the triggering mechanism of adjacent circuit breakers via a film hinge 19.
• the film hinge 19 links the coupling member 18, which is designed like a bolt, to a frame profile 20, which likewise protrudes on both sides of the spacer profile part 11 and engages in the housing recesses which are present in the assembly of adjacent circuit breakers.
• the coupling member 18 can be pivoted in the plane of the spacer profile part 11, the pivoting region being limited by the frame profile 20 which extends almost like a bell around the coupling member 18.
• a guide profile 21 is formed on the coupling member 18, through which the coupling member 18 can be guided perpendicularly to the spacer profile part during its pivoting movement in order to maintain its orientation.
• the guide profile 21 slides laterally with play on opposite housing recess surfaces, in which the arcuate passage for the engagement of the coupling member 18 is also formed.
• the frame profile 20 is integrated in a strut 22 which is formed between the spacer and centering sleeves 12 and 13.
• the strut 22 also has a compensation arch 23 on which a perpendicular to the orientation of the strut 22 Spacer tongue 24 is molded in the same thickness as the spacer profile part 11.
• a further strut 25 with a compensation arch 26 extends between the spacer and centering sleeves 12 and 14. Furthermore, a strut 27 with a compensation arch 28 is provided between the spacer and centering sleeves 13, the area between the struts 22, 25 and 27 is free of material.
