Definitions

the present invention relates to a microswitch control a remote operator for switching devices according the preamble of claim 1.
Remote drives of this type are used for electrical Switching devices such as miniature circuit breakers to operate remotely, in which the actuation knob the circuit breaker mechanically with the actuation toggle of the remote drive and this is electromotive is foldable.
Electric motor that has a so-called eccentric disc Steering wheel, preferably with the actuating link of the toggle is in operative engagement by means of a connecting rod and thus the rotation of the electric motor in one Converting swivel movement of the toggle.
Limit switches are used to control such a remote drive or limit switch-like on / off switch for the Actuation of the electric motor provided that the motor at stop at a certain angle of rotation at which the Remote control actuator toggle Has assumed the switching position.
This drive is preferably for switching a circuit breaker provided and has one on control lines connected electric motor. Via a gear and a cooperating power transmission mechanism (Connecting rod) is the drive with an operating knob of the circuit breaker coupled.
a gear and a cooperating power transmission mechanism (Connecting rod) is the drive with an operating knob of the circuit breaker coupled.
the switch-on pull rod engages in an arched backdrop a toggle wheel, which is concentric with the Control knob of the adjacent automatic switch in the drive housing is stored.
the knob has one Bearing position for an opening pull rod and a control edge to operate a lever.
the pull-out pull rod works with a ring-shaped recess of the steering wheel form-fit together, while the lever is fixed to the housing and by means of Control edge of the toggle wheel against the moment of one on it attacking energy storage is pivotable. From the lever actuated are a first microswitch for a switch-off signal and a second microswitch for a switch-on signal, each connected in series with the control lines. There is an incision all around the steering wheel Cam track formed, with which one the second Control lever acting on the microswitch interacts.
the known remote drive uses a complicated mechanism to control the electric motor drive for actuation the remote control knob.
Such a complicated mechanism is not only extremely difficult to assemble with the Risk of causing assembly errors in mass production but also shows control inaccuracies due to the Game of the respective relatively movably mounted Actuators on the prolonged use of the Remote drive, if applicable, to loss of function of the remote drive being able to lead.
the object of the invention is therefore a microswitch control of a generic remote drive to create which one compared to the above State of the art has simplified structure so is easier to assemble and less susceptible to faults having.
control wheel has two cam tracks for that Actuate two microswitches, one of which is a switch is an on / off switch for operating the electric motor and the other switch is a toggle switch between actuation of the electric motor for tensioning the toggle and an actuation of the electric motor at least for an intentional release of the toggle switches.
the assembly effort for the invention is reduced Microswitch control on mounting the two microswitches and the support of the steering wheel on a preferably formed in the housing of the remote drive Bearing base. Assembly errors are thus on one only a small percentage reduced, being prone to failure due to the small number of relatively movable components can also be reduced.
FIG. 1 there is a microswitch control Remote drive for switching devices, not shown, preferably circuit breakers essentially from one by an electric motor (not shown) driven steering wheel 1, a power transmission component, preferably a connecting rod or operating bracket 2 and a backdrop 3, the 4 on the toggle or articulated bracket Knob 5 is formed on one end face.
the Steering wheel points on its two faces a cam track 6, 7 for actuating microswitches 8, 9 on, as shown in Figures 3 to 6.
the steering wheel has a central one Bearing bore 10, the one on a journal not switch housing shown further can be plugged on turn freely on the bearing journal. Furthermore, it has Steering wheel 1 is an eccentrically arranged articulation hole or Socket 11 in which one end of the connecting rod 2 is rotatable is stored.
the first cam track 6 shown in FIGS. 1 and 2 in the present case consists of two cam track sections 12, 13, which are in series with each other in the circumferential direction of the steering wheel are arranged.
a second circumferential projection preferably a web 16 on the relevant end face of the Steering wheel formed, which is between the first Cam track 12 and the projection 16 forms a circumferential groove 17.
the second cam track section 13 has on it in the direction of rotation the steering wheel 1 (by the no further electric motor shown) front end one radially inward projecting paragraph 18, the one opposite the predetermined direction of rotation of the steering wheel 1 acting Undercut forms.
the radially inner one Edge of paragraph 18 in the direction of rotation of the steering wheel 1 via a continuously increasing ramp or Wedge 19 with the radially outer side flank of the circumferential groove 17 connected.
the connecting rod shaped as a control bracket 2 reaches into the switching curve at its free end 21 and is slidably guided therein.
the switching curve is shown in plan view.
the switching curve 21 is substantially one in length Quarter circle, being from one end from cone or in the direction of actuation of the toggle triangularly expanding.
the radially inner side flank the switching curve 21 is also wavy under formation an upper, cam-shaped dead center to prevent that the connecting rod 2 in case the gag triggers, not jammed in the backdrop.
Knob wheel 4 has a pivot hole 22 formed eccentrically.
the driving lever 23 likewise by means of one in the figures illustrated spring against the radially outer side flank the circumferential groove 17 is biased so that with one revolution the steering wheel of the driving lever 23 at its bent Bracket along the side flank of the circumferential groove 17 slides.
the on / off switch 9 takes on the steering wheel 1 such a position that one revolution the steering wheel 1, the first and second cam track section 12, 13 of the first cam track 6 an actuating tab 25 of the microswitch 9 can operate this in to bring an on position.
the switching distances 14, 15 the first cam track 6 are also designed such that when an angular position of the steering wheel 1 is reached, in which the actuation tab 25 in one of the two switching distances 14, 15 protrudes, the microswitch 9 in the off position is switched.
the two are Microswitches 8 and 9 arranged parallel to each other, 5, the second cam track 7 on the side opposite the first cam track 6 of the steering wheel 1 is arranged.
the second cam track too 7 has a cam track section 26 according to FIG around the circumference of the steering wheel 1 essentially extends a three-quarter circle, between the initial and end point of the cam track section 26 is a switching distance 27 of the second cam track 7 forms.
the second cam track becomes like the first cam track 6 7 by a web-shaped projection on the corresponding End face of the steering wheel 1, the above designated switching distance 27 of the second cam track 7 through a gap between the start and end point of the Web is defined.
the second microswitch 8 which is designed as a changeover switch, has also an actuating tab 28, which with the web-shaped Cam track section 26 is engageable to the Bring switch 8 in a one-pulse expected position.
the changeover switch becomes 8 switched to an off-pulse expected position.
the two microswitches 8, 9 are electrical as follows coupled with each other:
the on / off switch has a first contact pin 29 on which carries a permanent current, not shown Cable is connected and a second connector pin 30, depending on the switching position of the actuation tab 25 is in contact with the connection 29.
the Connector pin 30 of the on / off switch is not a Intermediate cable shown with an input pin 31 of the switch 8 connected, depending on the switching position of the switch 8 either with a one-pulse expectation connection 32 or an off-pulse expectation port 33 is connectable.
the connector pin 30 of the on / off switch is also connected to the motor electrically connected.
FIGS 3 and 4 show that switch position in which the knob 5 of the remote drive, not shown in its release position and the steering wheel 1 inclusive the actuating bracket articulated therein or Connecting rod 2 is in the toggle position.
the changeover switch 8, as in the 6 is actuated by the cam track section 26 and is therefore in its one-pulse expected position.
the on-pulse expectation port is in this position 32 with the input pin 31 of the switch 8 electrically connected. Furthermore located the operating tab 25 of the on / off switch in second switching distance 15 of the first cam track 6, so that the on / off switch 9 is in its off position.
the connecting rod lies in this switching position of the steering wheel 1 at its free end essentially at the according Fig. 2 left end surface of the switching curve 21 on or in the toggle operating position.
this pulse is on the on-pulse expectation port 32, through which Switch input pin 31 and the connector pin 30 of the on / off switch directly to the connected one Electric motor is passed, causing itself this corresponds to the pulse length by a few angular degrees twisted to the extent that the first cam track section 12 of the first cam track 6 with the actuating tab 25 of the on / off switch 9 comes into engagement and this in its on position switches.
an off pulse signal is sent to the changeover switch 8, d. H. applied to its off pulse expectation terminal 33, in the angular position described above of the steering wheel 1 with the input pin 31 of the switch 8 is in electrical contact.
the input pin 31 is as already described above, directly via the pin 30 of the on / off switch connected to the electric motor, whereby this driven according to the length of the off pulse signal becomes.
the toggle 5 can be flipped over in its clamping position by supplying an on-pulse signal to the on-pulse expectation terminal 32 of the on-pulse expected position switch 8 is applied, which again via the connector pin 30 the electric motor is passed on immediately.
This causes the electric motor to rotate a little, which, however, is sufficient for the actuation tab 25 through the first cam track section 12 of the first cam track 6 operated and the on / off switch 9 in its on-switch position is switched.
This is the continuous current on the input pin 29 of the on / off switch 9 applied to the connector pin 30, and via this to the electric motor forwarded.
the electric motor then turns until the steering wheel 1 an angular position occupies in which the operating tab 25th again in the first switching distance 14 of the first cam track 6 snaps and thus the on / off switch 9 in it Exhibition switches.
This movement is about the Connecting rod 2 to the left end of the switching curve according to FIG. 2 21 applied a force in the circumferential direction of the toggle wheel 4 acts eccentrically for its storage and thus flipped the gag 5 in its clamping position.
the connecting rod 2 moves along the switching curve 21, until it arrives at or near the right end according to FIG. 2 and thus a free pivoting of the gag in the case of a Allows release movement.
the present invention relates to a microswitch control a remote operator, preferably for circuit breakers with a motorized steering wheel that has a Connecting rod with a set of knobs in active engagement two microswitches depending on the position of the toggle controls for switching the electric motor on / off.
the steering wheel has two cam tracks for actuation of the two microswitches, one of which as one On / off switch for direct operation of the electric motor and the other is designed as a changeover switch which between actuation of the electric motor for tensioning of the toggle and actuation of the electric motor for one intended triggering of the toggle and / or a reset run toggles.
