Definitions

  • the invention relates to an electrical switching device, in particular a circuit breaker, with a device for accelerating the Switching on between a stationary electrical contact and a movable electric one removable therefrom Contact of the electrical switching device, the movable contact on one acted upon by a contact spring in the switch-on direction Swivel bracket arranged and to switch on with participation a shift lever in its contact position on the stationary contact is feasible.
  • a device of the type mentioned is already in DE-A-3335887.
  • this previously known device is a bracket that can be swiveled around a stationary axis a control pin provided.
  • This control pin engages a special backdrop guide with a retaining projection, which is formed in an additional backdrop.
  • This The link part is fixed at a distance from the swivel bracket pivoted.
  • the mechanics also see an articulation of the actuator on the same fixed axis like the swivel bracket in front, the actuator in one has an elongated hole parallel to the slotted element, in which the control pin also engages.
  • To the Closing the contact is the actuator via a Articulated rod applied.
  • the invention has for its object a device further developed in such a way that existing ones Switchgear without major design changes independent of the operating speed of the shift lever Contact switch-on speed is reached.
  • the device according to the invention is advantageous a holding element is provided, the attack on which by the Contact spring preloaded swivel bracket using the shift lever is detachable when switched on.
  • This allows the swivel bracket which is acted upon by the stored energy of the contact spring is suddenly released during switching on and under impact of the contact spring on the stationary contact, whereby any existing oxide layers penetrate become.
  • the invention thus realizes a so-called moment engagement, which counteracts the occurrence of switch-on arcs and ensures reliable contact closure, without being dependent on the actuation speed of the shift lever and without affecting the switch-off process becomes. This is especially the case with miniature circuit breakers essential.
  • the holding element can be attached to the swivel bracket at any suitable Attack place that does not affect the other functional flow impaired and adapted to the spatial conditions. According to a preferred embodiment of the invention, this applies Holding element in a preferably sawtooth-shaped engagement recess, preferably on the side of the swivel bracket.
  • This engagement recess can be made without much manufacturing effort Help shape the manufacture of the swivel bracket, whereby the engagement recess has a retaining edge or surface must to realize the holding attack by the holding element.
  • the preferred embodiment has the engagement recess as a sawtooth with an inlet and a holding flank the advantage that the holding element during the movement of the swivel bracket from the OFF switch position to the ON switch position can easily and reliably attack the swivel bracket.
  • Holding element made of a resilient material and is made of it Attack position on the swivel bracket can be moved away elastically.
  • the holding element also as a housing-fixed spring element with a contact and engaging portion may be formed.
  • a circuit breaker 10 is shown schematically, the one stationary contact 11 and one from the system position at this movable contact for contact separation 12, which on a leg 13 of a U-shaped pivot bracket 14 is arranged.
  • the swivel bracket 14 has one second leg 15, which is supported in a pivot bearing 16.
  • the leg 15 is by a compression spring 17 via a bell crank 18 acted upon in the contact closing direction.
  • the bottom end 19 of the compression spring 17 is stationary near the deflection area 16 in a housing 20 of the circuit breaker 10 held.
  • the opposite end 21 of the compression spring 17 is not shown in FIG Passed through a longitudinal slot in the leg 15, and with an angled part 22 of a conductor 23 connected.
  • the conductor 23 is connected via a connecting terminal 24 an electrical line can be connected.
  • a device 25 according to the invention is by a holding element 26 and, as can be seen in connection with FIG. 3, by a sawtooth-like recess 27 and a control surface 28 (Fig. 3) formed on a shift lever 29.
  • the sawtooth-like engagement recess 27 points in the area of the web 31 of the bracket 14 an engagement flank 32 and a contact surface 33.
  • the holding element 26 consists of an extended end of the contact spring 17 and is for lateral contact with the swivel bracket 14 Achievement of the intervention biased.
  • the upper end 30 of the holding element 26 is for contacting the on the shift lever 29 molded control surface 28 bent. 3 is by a curved arrow the pivot direction of the shift lever for the Switch-on movement shown.
  • On the end 30 of the holding element 26 has a straight arrow that the intended disengagement of the Holding element 26 from the sawtooth-like engagement recess 27 implies.
  • the shift lever 29 belongs to a release lever arrangement 35 of the Miniature circuit breaker 10 and acts with a strong contact-wrenching Switch spring 36 and with a manually operated Shift knob 37 to a latched standby position and an unlatched OFF position.
  • a strong contact-wrenching Switch spring 36 and with a manually operated Shift knob 37 to a latched standby position and an unlatched OFF position.
  • an attack formation 38 through which the leg 13 of the swivel bracket 14 against the Effect of the contact spring 17 when the circuit breaker is triggered 10 is movable into the position shown in FIG. 1, in which the holding element 26 rests on the web 31, however, itself is not yet in the engagement recess 27.
  • the trigger lever arrangement 35 can be triggered by a a certain tripping current and / or from an occurring thermal heating by a trigger device 39, which in Connected to a terminal 40 and above in Fig. 1 an arc extinguishing chamber 41 in the housing 20 of the circuit breaker 10 is arranged.
  • FIG. 3 illustrates the functional relationship between the Disengaging movement of the holding element 26 and for this disengaging movement responsible control surface 28 of the shift lever 29, which when turning the shift lever 29 counterclockwise takes effect in a second phase of the switch-on movement, after the holding element 26 in a first phase of the switch-on movement from its contact with the web 31 into the engagement recess 27 has occurred.
  • the innovation is particularly notable for its simple construction that allows in with little effort existing switching devices to the effect of momentary switching integrate. So is only one end 21 of the contact spring 17 to extend or alternatively a housing-fixed spring element to provide, which belongs to the movable contact 12 Swivel bracket 14 with an engagement recess 27 or latching point to provide and on the shift lever 29 a control surface 28 to be installed as a release notch to achieve the desired Ensure function.
  • This allows the invention Device without problems in an otherwise unchanged construction an electrical switching device, in particular one Insert the circuit breaker 10.
