Definitions
- the invention is in the field of electrical switches and is in the constructive design of one in low voltage networks the circuit breaker used, with a key switch with a ratchet mechanism is equipped.
- Switch locks used in the aforementioned circuit breakers serve as a mechanical link between the Drive members and the contact members and include all mechanical elements that the switching ratio when switching on - For closing relatively movable Switch contacts - and when triggered - to open the switch contacts - and the latching - locking of the contact apparatus of the circuit breaker in the respective switch position - serve.
- the ratchet mechanism is a commonly used one Construction materials in switch locks.
- a known device for controlling the activation of a Circuit breaker has a switch lock in which a release ratchet lever on a release half-shaft supports.
- the tripping half-wave serves the contact members to latch in the on position and this latch to be able to pick it up again.
- Unlocking done by movements of actuators or release devices transferred to functional elements (carrier, bracket) with the central shaft of the release half-wave are connected in a manner not shown and which protrude radially from this shaft.
- the well-known switch lock also has a switch-on half-wave on which a Switch-on pawl lever supports.
- the swiveling of the switch-on half-wave is the same in a half-wave region of the central shaft of this Half-wave-assisted ratchet lever released.
- the Switch-on ratchet lever is mechanical with an energy store connected, its energy after the release of the switch lever is transferred to the contact members in this way, that the switch contacts are closed and thus the circuit breaker is switched on.
- For swiveling the switch-on half-wave are also movements of actuation or Release devices on from a central shaft of the Switch-on half-wave radially protruding functional elements transferred (DE 43 33 828).
- actuating arms for force application or Actuating arms for locking elements from the same Semi-finished product and less with the processing methods mentioned are easy to manufacture, you combine it as a turned / milled part trained central shaft for example with as Plastic pointed part or formed as a sheet metal part Functional elements, the design of which in Area of the central shaft a correct, permanent and non-rotatable connection with the central shaft ensures.
- the switching shaft of a low-voltage circuit breaker and that from this shift shaft radially protruding lever than manufactured in a metal casting process to form one-piece switching shaft unit.
- the Shift shaft is used to transmit a driving force of the drive elements on the movable switch contacts.
- the levers protruding from the central shaft of this selector shaft mechanically with the drive members and / or the contact members connected. Switching shafts of this type are therefore subject to not the high demands known for latch mechanisms with regard to the surface quality (DE 197 27 853 C1).
- this object is achieved in that the shaft and the radially protruding functional elements Half wave as a one-piece manufactured in a master molding process Metal bodies are formed.
- primary molding process are casting processes or Sintering processes meant, in particular the investment casting and the MIM (metal injection molding) process.
- Such primary shaping processes allow for a more constructive one Freedom of design the half-waves as one-piece high-strength Components with uniformly high surface quality and dimensional accuracy to manufacture.
- the individual functional elements require here to the correct and rotationally fixed arrangement no special design on the central shaft and can therefore be lined up axially closer together his. This allows the axial length and accordingly also the necessary span of the central shaft as a whole be chosen much shorter.
- the cross-section of the central shaft can also span significantly smaller than in the known half-waves be because of the bending stress of the central shaft through the acting force of the supported ratchet lever is less.
- a half-wave dimensioned in this way also has a low weight and thus a low moment of inertia and can therefore, especially in the event of short circuits follow acting forces faster.
- a further development of the invention provides that at the central Shaft is additionally molded to a mass balance to increase the static shock resistance.
- This mass balance can be designed like a cam. To the constructive Freedom in the design of the functional elements through the It is recommended not to restrict the arrangement of the mass balance it is mass balance at one end of the world central shaft and the functional elements on the other Arrange end.
- FIGS. 1 An exemplary embodiment of the invention is shown in FIGS. 1 shown to 3.
- Figure 1 shows a key switch with a switch lever 1, which is supported on a switch-on half-wave 2, and a switch-off pawl lever 3, which is on a release half-shaft 21 supports.
- the switch-on half-wave 2 and the Trigger half-wave 21 are identical. It is the half-wave 21 with respect to the half-wave 2 - by 180 ° in the the central shafts of both planes including the half waves rotated - arranged.
- the half-wave 2 has one on its two Ends with central shaft 5 provided with bearing pins 4, the at one end several radially protruding functional elements 6, 7, 8, 9 and at the other end a mass balance 10 carries.
- a mass balance 10 Approximately in the middle of the central shaft 5 is a half-wave region provided with a latching surface 11 12 trained.
- the half wave 2 is as in one Investment casting, one-piece, made of steel Metal body formed.
- a first functional element 6 is as an operating lever formed of a first actuating pin 13 and a Hook 14 for receiving a leg of a return spring 15 (see FIG. 1).
- a second functional element 7 has a second actuating pin 16 and is with a cam-like contour 17 (see FIG. 1), the the axial position securing of the return spring 15 is used.
- Two other functional elements 8, 9 are designed as flat contours and also serve the position of the return spring 15. They protrude - offset by 90 ° relative to the cam-like contour 17 - from the central shaft 5.
- the one at the other end of the Central shaft arranged mass balance 10 serves as Counterweight against the mass of the radially protruding functional elements 6, 7, 8, 9 and causes a shift of the Center of gravity of the half wave 2 towards the central one Shank 5. This ensures that the weight forces of the functional elements alone no swiveling the half-wave is caused (shock resistance).
- the first actuating pin 13 of the tripping half-shaft 21 is acted upon by electrical and / or mechanical tripping or actuating devices 18 (not shown in detail) in such a way that the tripping half-wave 21 rotates slightly counterclockwise executes and thus the switch-off pawl lever 3 loses its support on the latching surface 11 and is released.
- the second actuating pin 16 of the closing half-wave 2 is acted upon by electrical and / or mechanical triggering or actuating devices 19, likewise not shown in detail, in such a way that the closing half-wave 2 is rotated clockwise by a slight angle and the closing Pawl lever 1 loses its support on the latching surface 11 of the switch-on half-wave 2.
- the surface quality and the concentric position of the latching surface 11 are decisive for an exact tripping and switching on of the circuit breaker at predetermined angular positions of the half-waves and under the action of precisely predetermined forces.
- the latching surface 11 can initially be raised by the master molding process and can be reworked by a machining process.
- the first actuating pin 13 of the closing half-shaft 2 serves to open the circuit breaker and is actuated by an empty switching lever 20, which is not shown in detail.
