Definitions
- the invention is based on a shift lever connection according to the preamble of claim 1. With a such a shift lever connection becomes a synchronous actuation the pole of a multi-pole switching device is reached. Is preferred such a shift lever connection in switching devices, such as especially line fault current or motor protection switches from Low voltage distributors used. Such switches have often two, three, four or possibly even more than four like poles.
- the invention takes on a prior art of shift lever connection Reference, as in that of the patent applicant in autumn 1989 published manual "Innovative installation with smissline" is shown on p.6.
- the shift lever connection after the Prior art contains a sheet bent as a U-shape trained bridge part. This sheet is two or three around a common axis swiveling and each as an operating handle trained lever arms of the shift lever of a two-or three-pole circuit breaker and thus causes the rigid coupling of the shift levers and thus a synchronous Actuation of the individual switch poles.
- the manufacture and Assembly of such a bridge part is relatively complex.
- the invention as set out in claim 1 lies the task is based on a gear lever connection of the beginning Specify the type mentioned in a simple and one for one Suitable for mass production.
- the shift lever connection according to the invention stands out by simply pressing the pin in the spreading parts of the shift levers to be connected are extremely simple and inexpensive in a suitable for mass production Process can be made.
- the so manufactured Connection is characterized by high strength and a large Operational safety even with heavy loads. In addition it does not affect the handling of the gear lever handles nor the aesthetic design of the multi-pole switching device.
- this shift lever connection according to the invention completely regardless of the nature of the shift lever and can by simply cutting the pen to length very easily to different wide switch poles and switchgear with any many switch poles can be adjusted.
- the shift lever connection shown in Figures 1 and 2 does not have a pin 1 and three about a common axis 2 of the Switching device shown pivotable shift lever 3.
- the Shift levers 3 are made of a plastic, typically one Thermoplastic, for example based on an amide, and are formed each in a pole housing, also not shown Switchgear pivoted about axis 2.
- the three poles can be designed as circuit breakers if the switchgear is designed for example, the three phases of a three-phase system.
- Each of the three shift levers 3 is designed with two arms and has each with an actuating element, not shown on a contact arrangement acting lever arm 4 and a trained as a handle 5 and from the pole housing of the switching device further lever arm led to the outside.
- the Lever handles each have an elastically deformable expansion part 6 and is in the expansion parts 6 parallel to the pivot axis 2nd aligned pin 1 pressed.
- the structure of the pin 1 can be seen from FIG.
- This pen is preferably cylindrical. Instead of a round profile but he can also any other in the undercut 9 of the Have slot 7 matching profile and, for example, elliptical, semicircular, square or rectangular cross-section exhibit. It is particularly important that the pen after spreading the leg 8 of the expansion part 6 in this way in the undercut 9 is stored in such a way that it can no longer be adjusted without great effort can be removed outside. Depending on the diameter of the pin 1 and The size of the undercut is pin 1 in the undercut 9 spread and pinched or only spread held. These different brackets cannot manufacturing tolerances to be avoided.
- the pin 1 has at least one between two shift levers arranged thickening 11.
- This thickening 11 can be special can be produced simply and inexpensively by notching. in the in general, for example, three or three is enough four notches 12 to produce a side removal of the Pin 1 with great security preventing thickening 11th already out.
- the shift lever connection according to the invention can be special be manufactured easily and inexpensively. On the one hand, this is therefore possible, because in the manufacture of the in general injection molded shift lever 3 used the slot 7 and the undercut 9 are molded in without additional effort can be. On the other hand, this is also possible because the Pin 1 is easily cut to a desired length adjusted and the cut pin under rigid coupling of the three shift levers 3 without great assembly effort across Swivel axis 2 into the slots 7 or the undercuts 9 can be fitted.
