Definitions
- the invention relates to a safety relay according to the preamble of Claim 5, arranged with an electrically insulating support member and on the support member an electromagnetic drive, at least one positively driven control contact and at least three positively driven load contacts, as well as the use of one such a safety relay and a switching device with such a safety relay.
- the contacts essentially consist of two parallel, flat contact springs, each with a contact head, a spring foot in a distance from the contact head and at least one connected to the spring foot Connection part, especially one or two pins.
- the contact springs sit with the Feather foot firmly in the carrier part.
- a positively driven relay is a relay in which the Contacts with a common drive-related movable comb are positively guided and in which at least one working contact and a break contact is provided.
- Forced management means that one of the Contact springs of each contact is close to the head at a fixed stop and the engages others in the comb in such a way that it Comb is moved. This ensures that when a contact welded, either the welded contact is torn apart, or the Comb can not be moved and therefore the other contacts in the by the Welding position.
- safety relay refers to a safety relay according to the standard EN 50205 understood.
- a safety relay according to standard EN 50205 the clearances and creepage distances between the control contact and the load contact Requirements of the IEC 61810-5 and IEC 664-1 standards.
- the content of these standards will be as known to the person skilled in the art and as part of this application viewed.
- AT-A-379254 is an electromagnetic hinged anchor relay with positively driven heavy current contacts known. With this one borders Transverse wall a space for the contacts against a space for the Drive system.
- the contacts consist of two flat contact springs with a foot part are arranged in a base plate.
- the contact space is with an in a longitudinal dividing wall running perpendicular to the base plate and on both sides of this vertical transverse partition walls in several Contact chambers divided.
- the non-moving contact springs are each on one Counterpart.
- the moving contact springs are connected to the armature connected slide moves.
- the slide is above the longitudinal partition and Cross partitions arranged and lies with a horizontal plate on the top Faces of these partitions. It indicates the compulsory guidance of the moveable Contact springs have narrow slots in this plate.
- the slide points also analogous to the contact chamber walls under the slide above the Plate on a longitudinal partition, a transverse boundary wall and transverse partition walls. Together, these form an analog chambering in the head area of the contacts.
- This relay points between the longitudinal partition and transverse partition walls on the one hand and the slide, on the other hand, straight airways between the contact springs of neighboring contacts.
- a safe separation of the excitation circuit from the contact circuit and the Contact circles with one another are only generous with regard to air gaps Dimensioning of the distances between the conductive parts possible. The relay is therefore large enough to meet the relevant safety standards fulfill.
- EP-A-0 938 120 is a multi-pole, electromagnetically driven Contactor known. This has two opposite fixed contacts and for each pole a movable contact bridge.
- the contact bridge has two connected contacts that are assigned to the two fixed contacts.
- the contact bridges for the different poles are arranged on a common, movable support. Becomes the carrier is moved by the electromagnetic drive, so the fixed Contacts interconnected across the bridges by placing the bridge contacts against the fixed contacts are made, or separately if the opposite movement is performed.
- the carrier has an insulating wall meandering around the contacts on, one for each contact pair consisting of fixed and movable contact forms three sides closed chamber, being adjacent in the direction of movement Chambers on opposite sides are open. The firm contacts are enough with theirs Contact heads from a fourth, also open side in this the contacts of the Chambers enclosing contact bridges.
- the Number of parts for switching and the possible sources of error when switching from Current drawers, in particular of short-circuit-proof, three-phase electric motors from 1 up to 4 kW of power.
- a positively driven relay is to be created be on voltages of over 250 V, especially those in three-phase Mains current occurring 400 V relative voltage between the phases, is designed and meets the requirements for a positively driven safety relay.
- a positively driven safety relay according to the preamble of claim 5 for switching with the three load contacts connected three phases of a three-phase mains voltage is used.
- Two series-connected relays are expediently used for synchronous switching of the three phases used in the two relays.
- the relay for Direct switching of the reference current can be done by two contactors connected after the relay and the appropriate wiring of the contactors can be avoided.
- the reduction of The number of parts leads to a reduction in the possible sources of error.
- the double The relay is designed for safety. Whether two relays connected in series or one Twin relays are used is not of concern.
- the three phases of the invention Mains current connected to the load contacts of the safety relays.
- Safety relays in two separate relays or together in the form of a twin relay intended.
- a relay according to the preamble of claim 5 are advantageous individual contact springs of the load contacts by one from the spring foot to at least Insulating wall panel close to the head and from one side of the relay to the other separated from each other.
- the wall panel on the sides is opposite Angled direction and each bend with a different one of the two adjacent wall panels connected. This forms the wall panels and Bends together a contiguous to the contact springs of the Load contacts meandering partition.
- This means the requirements are Creepage distances between the load contacts in a confined space, because the Creepage distance between the spring feet of the contact springs of adjacent contacts bends around.
- the meandering is interlocked by two Molds available. These shapes are transverse to the direction of movement of the comb a relative translation apart and put together.
- the contact springs of the control contacts expediently have one smaller cross section than that of the load contacts. This allows a material and space savings in the control contacts.
- the cross sections are the springs of the load contacts are larger than those of the control contacts. This not only has the advantage that higher currents with lower heating of the springs of the load contacts these can flow through, but also that the spring force of these contact springs is higher is, and so the force to release the contact is increased and therefore greater Welding of the contact heads can be solved than with smaller spring cross sections.
- the contact springs of the load contacts are expediently in a linear one Row arranged one behind the other in the direction of movement of the comb and stress the same width as two control contacts next to each other. This allows an easy one Control of the contact springs with a common comb.
- the stop is advantageous for the contact springs, which do not engage the comb are through a lip on the wall disc between the contact springs of a contact. Thanks to the bends, this wall panel is very stiff and can absorb sufficient forces even in the heated state to Retain contact spring securely.
- the stop can depend on the embodiment one or the other of the two toothed molds are formed. As a result, various combinations of rest and work contacts are through minor changes to the mold available.
- the wall disc between the contact springs of different contacts is sufficient advantageously at least up to between the contact heads.
- a chamber is formed for each individual contact spring, which is strong even Contamination from burnt-off material of the contact heads ensures safe separation of contacts guaranteed from each other.
- the wall panels between two neighboring ones Contacts is led beyond the contact heads to the air gap between to extend these contacts.
- the wall disks between the contact springs are expedient of the same contact and the bends are equally high. Lower angles would affect the rigidity of the wall panel, higher the view of the Affecting contact heads.
- the spring foot is advantageous the contact head laterally offset, so that the pins of the two contact springs one Load contacts are arranged on opposite edges of the carrier part, the heads however on a center line in between.
- the pins of adjacent contact springs are located therefore each on the opposite edge of the relay and the pins on the same edge of the Relay with double spring spacing. This makes the necessary and safety distances between the pins in a very small space observable.
- the spring feet are expediently on the open side of the Chambering arranged so that slots in the carrier part for receiving the Cut the contact springs as little as possible into the carrier part.
- the Load contacts advantageously each have two pins to the springs compared to one pin double connection surface with a connecting part, e.g. a circuit board or one Relay socket.
- control contacts are advantageous with respect to the direction of movement of the Comb arranged side by side and by one in the direction of movement of the comb directed septum separated. This is the most space-saving arrangement and ensures adequate separation of contacts thanks to the one with the partition reached chambering.
- the comb points open an elongated opening in the area of the partition and pass the partition with it its comb-side edge through this opening.
- the partition wall advantageously forked on its comb-side edge.
- the fork forms a furrow along the direction of movement of the comb.
- the contact springs of the load contacts are also angled with respect to their axis pin contact head so that the head is on a center line, the two pin on one or the other edge of the carrier part are arranged, so the contact springs Load contacts are nevertheless essentially flat and of the same design. You differentiated only by the length of a head end projecting above the contact head End, so that the active contact springs with a long end engage in the comb, the short-ended passive not.
- FIG. 1 and 2 each show two relays 11, 11 'and 11 * connected in series. with which the three phases 13, 14, 15 of a network connection are switched, to safely switch a three-phase motor 17.
- Such a circuit is e.g. applicable in a security monitoring of a press, a cutting machine or the like and e.g. to be connected to a light curtain that monitors the danger area.

- the control contact 21, 21 ' is e.g. under 12 or 24 volts.
- the separation of the load contacts 23, 24, 25 and 23 ', 24', 25 'from each other is 400 volts designed.
- the separation between the load and control contacts corresponds to double or reinforced insulation. This could also be makeshift e.g. on known relay of the applicant's SIR series, which has 10 contacts, can be used by alternating every second contact on the one and the other side of the 5 and 5 contacts separating partition with one phase is connected.
- the relays are activated and deactivated.
- a pulse or control current e.g. caused by an interruption of a Light beam from a light curtain, triggers the switching of the relay 11, 11 'in a known manner out. Should e.g. a contact 23 of the relay 11 does not open when the relay 11 is deactivated, it can be assumed that the upstream contact 23 'of the relay 11' opens, thereby interrupting the power supply to phase 13.
- the Control of relays 11 and 11 ' prevents the two from switching positions Relay 11, 11 'activates relay 11, 11'. The different switching state is determined on the positively driven control contacts 21,21 '.
