Definitions

  • the invention relates to a contact arrangement for a circuit breaker, in particular an auxiliary and signal switch, in which a spring-mounted contact lever pivotable about a fixed pivot point can be reversed by a mechanism into different switching positions marked by fixed contacts and limiting its pivoting range.
  • Such contact arrangements are known. Sufficient contact pressure and the required erosion reserve are generated via a contact pressure spring, which either acts as a separate part on a rigid contact lever or the latter is also designed as a leaf spring.
  • the known arrangements therefore have the disadvantage that, in addition to an opening spring as an energy store for the switch-off movement, a contact pressure spring is also required.
  • the invention has for its object to design the contact arrangement in a self-switch of the above type in such a way that the contact pressure spring which has been customary up to now can be saved with the same requirements.
  • the invention has the advantage that the opening spring for switching off the mechanism also generates the contact pressure, which can be set precisely because of preselectable lever ratios between the two support points, at the point of application of the spring and the contact points. Furthermore, a self-cleaning effect of the contacts can easily be achieved by a special design of the support points without additional effort.
  • the contact arrangement for a self-switch is accommodated in a housing 1, in which a toggle 2 can be pivoted about a fixed pivot point 2a via a hinged plunger 3 to a latching point 3a acts.
  • the other latching partner is arranged in a manner not shown on an intermediate lever 4 which is rotatably mounted on an axis 5 fixed to the housing.
  • a contact lever 6 having incisions 6a is held securely only in that a tension spring 7 with its eyelet 7a engages over the incisions 6a and is guided in lateral notches 4b of the intermediate lever, presses the contact lever 6 onto the intermediate lever 4.
  • the other eyelet, not shown, of the tension spring 7 is suspended in the housing.
  • a double contact 6b which interacts with two fixed contacts 8 and 9 arranged in the housing.
  • Lines 8a and 9a lead from the fixed contacts to connecting terminals 8b and 9b.
  • the contact lever is also connected to a connecting terminal 6d via a movable line 6c.
  • the circuit breaker is preferably provided for coupling to a contoured circuit breaker of the same shape, adjacent in a parallel plane, not shown, the trigger mechanism of which can act on a transmission lever 10 via a pin 10a by means of an opening 1a in the housing.
  • This in turn is pivotally mounted on an axle 10b fixed to the housing and can actuate the latching point 3a via an extension 10c.
  • the lever arm 4a of the intermediate lever on the side facing the contact lever has a direction in which an imaginary extension outside of the area between the two fixed contacts laterally on the fixed contact 8 would walk past.
  • the contact lever 6, which is designed as a flat and rigid part and lies firmly against the intermediate lever 4a in the middle pivoting range can only pivot with the double contact 6b as far as the fixed contact 8, so that it only rests linearly at the point 4c on the intermediate lever and otherwise from the the latter has lifted against the action of the tension spring 7.
  • the two linear support points 4c and 6e which in the embodiment according to FIG. 1 are simplified by the ends of the intermediate lever 4 and the contact lever 6, can of course also be formed by separately shaped bearing blocks, for example be formed on the intermediate lever. With these pedestals, between which the tension spring 7 acts, the tilting effect and thus the contact force can then also be achieved.
  • the dimensioning of the contact force is determined by the force of the tension spring 7 and the selected lever ratios.
  • FIG. 2 A special form of support between the contact lever 6 and the intermediate lever 4 is shown in FIG. 2.
  • the contact lever 6 is provided with two inclined surfaces 6f, 6g, which are connected via a web 6h.
  • the lever arm 4a of the intermediate lever is provided opposite the inclined surfaces with roller-shaped support surfaces 4d and 4e in such a way that the inclined surfaces lie linearly on the support surfaces under the action of the tension spring 7 and there is still a greater scope between the web 6h and the lever arm 4a .
  • a force that acts alternately on the contact lever now causes a rocking-like relative movement between the contact lever and the intermediate lever, since the inclined surfaces 6g, 6f slide along the supporting surfaces 4d, 4e until the web 6h comes to rest on one side on the lever arm 4a.
