Definitions
- the invention relates to a switching device with a first movable contact carrier, which is a first recess has, into which via a first housing opening of the switching device, Depending on the operating state, a lock is spring-loaded intervenes.
- From DE-OS 14 47 403 is a mechanical lock for two components, for example for two contactors with each other, known. Both components are kept freely movable here, that when moving a component through one on this exerted force from the rest position, the other component is locked in motion. Between the two components are two displaceable organs supported by one another magnets attached to the components against one each Are held. The components are reciprocal Resting points provided in such a way that with a relevant Organ one component snaps into place as soon as the other component Rest position while canceling the magnetic effect in relation to this Organ leaves.
- the US 4,385,214 discloses two push buttons, which by one Locking mechanism are interconnected. Hereby it is ensured that only the contact of the a push button can be closed during the other pushbutton remains open.
- the invention is based on the object Switching device of the type mentioned above a mechanical latch to create the after switching on the switching device Failure of the power supply the ON position of the contact carrier maintains.
- Another object of the invention is that Switchgear so that with the help of an electrical Signal the mechanical latch can be released.
- the first-mentioned object is achieved according to the invention by that the lock at the transition of the switching device into the ON position engages in the first recess, and that the Switchgear is connected to an unlocking device that has a second movable contact carrier in which a second recess is present, into which a second Opening of the unlocking device housing in the OFF position a first arm of a rotatably mounted angle lever engages, that when the unlocking device is switched on swings around that he operates the lock with his second arm and thus releases the first contact carrier.
- the lock is designed as a pawl is, which is rotatably mounted in a bearing, because the pawl can be trained as a part that takes up little space and the bearing is in the same version as with reversing combinations e.g. can be used by shooters. So that's the camp a part that is inexpensive to manufacture in large quantities.
- the switching device and the unlocking device are advantageous each implemented by protection.
- the first housing opening in a first side wall of the switching device is provided and if the second housing opening in a second side wall the unlocking device is provided.
- the first switching device e.g. a protection by to expand an auxiliary switch attachment on the front.
- the front design of the device can be retained and the risk of contamination can be kept low.
- a mechanical latching of a switching device e.g. a protection, of which a section of the housing with a first housing opening 2 in a first side wall 3 and a first contact carrier 4 with a first recess 5, which is opposite the first housing opening 2.
- a second lies parallel to the first side wall 3
- a lock designed as a pawl 11 is rotatable in one between the two side walls 3.6 shape-coded bearings 12 stored.
- the bearing 12 is in his Shape coding adapted openings 13,14 shown in FIG 5 in the side walls 3.6.
- One on the jack 11 on the one hand and on the second side wall 6 on the other hand supported compression spring 15 acts on the pawl 11 in the direction of the first Side wall 3 acting spring force.
- OFF state is the first contact carrier in an upper position and the pawl 11 is supported below the first recess 5 on the first contact carrier 4.
- One on the switching device 1 rotatably mounted angle lever 16 engages with its first Arm 17 in the second recess 9 in the second contact carrier 8 of the unlocking device 7.
- a second arm 18 of the bell crank 16 is angled at 90 ° to the first arm between the pawl 11 and the first contact carrier 4th
- the angle lever 16 is thereby rotated and with its second arm 18 pivots the pawl 11 from the first Recess 5 of the first contact carrier 4 out, so that this moves upwards in the direction of the arrow according to FIG.
- the release can also be done manually using the switch position indicator 23 of the contact carrier 8 take place.
- the formation of the pawl 11 and the angle lever 16 is in individual reproduced in FIG 3 and FIG 4.
- the jack 11 is mounted rotatably via pin 20 and has a beveled end Projection 19, the mechanical latch into the likewise tapered first recess 5 of the first Contact carrier 4 immersed.
- the bevels allow on tolerance compensation in a simple way.
- the angle lever 16 is provided with a recess 21 through which the pawl 11th immersed in the assembled state.
- the second arm 18 of the Angle lever 16 has at the end a delimiting the recess 21 Web 22 on the pawl when unlocked 11 pivoted.
- the bearing 12 is hammerhead-shaped on one side Form-coded training to make a justified Installation in the adapted openings 13, 14 in the Side walls 3.6 of the switching device 1 and the unlocking device 7 ensure as indicated in FIG 5.
- FIG. 6 shows a protection 1 with those for mechanical latching and the unlocking required parts 11, 12, 15, 16 including the unlocking device 7.
- the protection 1 and the unlocking device 7 are over Connecting elements 24, which project on laterally projecting ribs be pinched, held together.
- the inventive design of the mechanical latch and unlocking is characterized in that as a switching device as well as series-produced unlocking device Sagittarius can be used.
- Sagittarius series-produced unlocking device
