Description
Technical field
The utility model relates to and a kind ofly is used to change connector especially according to the device that is subjected to the state exchange electrical connector of supervising device, especially according to the described safety switch of claim 1 preorder.
Background technology
This device is for example known from DE 43 28 297C1.This device partly has the conversion equipment that is used to change electrical connector at lower house, and has the opening that is used to insert actuator at head.Actuator makes changeover panel be oriented the right angle with direction of insertion on its rotation and rotates.Have at top, the cover of changeover panel surface and conversion equipment to be activated and form the conversion plunger that is electrically connected thus, and this conversion plunger can be fixed on by electromagnet and locks the also position of lock actuator thus of changeover panel.
From DE 43 32 500 A1, be known that a kind of locking device that is used to monitor movable protection mechanism; have and be positioned in the housing and two position switchs of separate work, can described position switch be activated by stretching into and pass the conversion reed that housing head has recess.
Known a kind of safety switch from DE 196 49 717 A1, its head have two and insert opening, and they determine that jointly actuator is in two direction of insertion that the right angle is set.According to the insertion opening that actuator inserts, changeover panel turns to one or rightabout.By proper device, changeover panel can be fixed its initial position or have the actuator that inserts fully.
Be known that from DE 197 11 588 A1 a kind of actuator and device all have the safety switch of signalling, can implement contactless signal transmission by described signalling, thereby optionally cause the conversion of electrical connector.The joint of the magnetic field force by axially movable plunger in the actuator openings is realized the locking of actuator in device.In order to determine whether actuator inserts and suitably locked, the position of the position of actuator in device and locking plunger all must be scanned and interrelate with the logic AND function.
In known devices, actuator must take out from device in a side identical with its insertion device.So especially, aspect the monitoring of the protective device of the modern machine of sliding window or sliding door or machining center, cause defective having the removable and part of direction.These defectives are in addition when the monitoring of locking that needs safety device and locking even more obvious.
Summary of the invention
This shows that the problem that the utility model solves is to utilize a kind of device, but it does not generally adopt a plurality of safety devices of being monitored and can be with the monitoring locking of the cost implement device of minimum.
Described problem can be passed through the disclosed device solves of claim 1.Specific implementations of the present utility model obtains open in the dependent claims.
The utility model discloses a kind of safety switch, comprising: the housing with first side and second side; Be positioned at the actuator socket in the housing; And the ejector that is used for discharging actuator from the actuator socket; It is characterized in that housing is configured to have and makes actuator to enter housing and to withdraw from the structure of housing from second side from first side.
Therefore because actuator can be removed from device in second side, can realize that actuator passes device, for example it is removable or can be installed on the annular safety device at both direction.Should be realized that first and second sides, have the different area of restraint device, the area of plane preferably at device.Usually, described device has housing, and it holds the translation building block of preferred conversion electrical connector.By the opening on the housing, actuator can be inserted into or take out.For the device that comprises changeover panel, changeover panel and device or its housing link to rotate by actuator.Changeover panel can rotate on both direction according to the side that actuator inserted subsequently.Two direction of rotation can cause conversion operations subsequently.Can remove head from the remainder of device case with the opening (a plurality of opening) that is used for actuator.Preferably, this head has opening in three sides, and actuator can insert and be removed in second side relative with first side from first side.By connecting the 3rd side of first and second sides, actuator can be fixed on the device of being monitored.Actuator has U-shaped cross-section in the present embodiment.Actuator can also take out or insert the 3rd side in the 3rd side from device.Described device can also be fixed on the device monitored for example on sliding door or the protective cover, and they can be fixed on the framework of device for example movably with respect to immovable actuator in this application.
Because actuator can pass device, therefore the device of design can be used in nearly all occasion by this way, especially can be used for the ring protection device.Although of course, not specificly must go out actuator at its side-draw that inserts device.
Because actuator can be fixed in the device, especially at least in part with the profile fit system fixing and/locking, therefore can postpone to be subjected to for example closure state of supervising device to reach static until lathe by the device capping.When being in, machine can follow the release that manually or automatically realizes locking when static.
Because described device comprises the actuator socket, this socket can form releasably to lock and engage with actuator, therefore must each insertion of actuator be locked.Actuator socket and actuator especially be designed such that they at least in part profile be combined together.Lock because of the preferred specific implementation that moves at an angle of 90 of the cross-section direction of insertion of actuator subsequently.Even utilize less latching force also can obtain reliable locking effect therefore.For this reason, actuator is connected in device or the mechanism movably, and especially pivoting connects.Alternative or additional to it is that actuator socket or its parts can also be designed to removable.Locking engages and preferably effected locking joint effect owing to the weight of actuator has been strengthened, and therefore can save to be used to lock mobile additional drive system.As alternative or additional considerable be to adopt accumulator, for example compression spring of actuator, Electromagnetic Drive or pneumatic propelling is to force the actuator locking to engage and/or to keep locking to engage.
Because the actuator socket forms the actuator tilt shape near the surface, therefore need not additional drive system and just can realize that actuator rises, locking subsequently is bonded in the actuator socket.Linear or spherical inclined-plane helps actuator or protective device to have higher gait of march, and actuator engages reliably or is locked in the actuator socket simultaneously.The inclined-plane can be towards all lateral orientation, and actuator inserts in the device or from wherein being removed from this inclined-plane.
Because the actuator socket has locking component rotatable, that especially can pivot and connect, it can produce when actuator inserts, so actuator can immovably for example be fixed on basically and is subjected on the supervising device.For example, the actuator socket forms skewed locking component, and it can produce when actuator inserts by this way, and promptly it abdicates path for actuator so that actuator reaches the position that engages with the locking of actuator socket.Actuator one reaches this position, and locking component just for example forms locking surface by being pivoted back to its initial position to actuator.Engage in order to unclamp locking, locking component pivots in the mode that actuator can be removed from device once more.
Because actuator and actuator socket have contactless cooperative signalling, therefore can save the movable part that is used for transmitting actuator movements in the additional especially device to the conversion plunger.Certainly, the electrical connector that is converted for example remains and realizes the contact conversion by the relay of signalling addressing.Preferred electric signaling device can also be realized the identification of knowing of actuator by suitable coding.The signal transmission is not that contact loads and especially by wireless, for example light or undertaken by radio.Can be configured to right signalling in several ways.
For example, preferably being fixed on only has one can send signal or information in two signallings on the device, and another signalling provided is signal reflection wholly or in part to emission basically.Alternatively, another signalling sends back to it in signalling with can receiving the signal of emission and constant or independent changes.Can on one or two direction, transmit in this simulation and/or digital signal.Preferably, one that especially is fixed in the signalling on the device also provides power to operate another signalling, preferably in visible or invisible frequency range with the form of electromagnetic radiation.
Owing to only be not locked in the device just to be in and just can carry out the signal transmission when locking engages, the AND function that therefore can save the additional locking of actuator, especially locks the additional queries of plunger position and have the actuator position inquiry not extensiblely at actuator and actuator socket at actuator.In the locking of actuator and actuator socket engaged, first and second signallings were directly opposite one another.Especially, they can be positioned on the relative locking surface.Preferably, be positioned at secondary signal device in the actuator socket and be arranged and be configured to the surface of actuator backward, make electromagnetic radiation by its emission have directional characteristic towards the position that is in actuator first signalling under the locking engagement state from the actuator socket surface.Although actuator still is not in the locking of actuator socket and engages thus, also can guarantee to prevent wrong closure, just got rid of and between two signallings, had the signal transmission.
Because the actuator that described device only utilizes being used to of being provided to change connector just obtains operation, therefore guaranteed the processing safety of device.Realize that this point is especially because device has the narrow and/or dark slit that is used to guide actuator, make the actuator socket not pass described slit from the outside and enter, reach the degree that the actuator that can not utilize the non-device that is used for changing described device to make described device conversion and/or engage with the actuator socket is thrown off from described joint at least.This point for example utilizes the flush joint crack of three side openings and U-shaped cross-section to realize, actuator passes the side that described flush joint crack can be directed into relative positioning from first side.By adopting first and second signallings to improve processing safety,, and only utilize the identification conversion connector of coupling so for example by being stored in the code word identification actuator clearly in actuator first signalling.
Comprise tripper owing to be used for the device of release actuator locking, therefore can carry out release automatically.Especially satisfactory is the accumulator or the compressed-air atomizer of electromagnetism or pneumatic actuation ejector, form of springs, and this depends on by spring force still is that magnetic force is still realized the locking of actuator in the actuator socket by gravity simply.
In appurtenance right and following description, disclose other advantages of the present utility model, feature and details, described several embodiments in detail with reference to accompanying drawing in the following description.By this combination, disclosed each feature is independent or all very important to the utility model with any combination in claims and the specification.
