Definitions

  • the invention relates to a contact spring arrangement for polarized electromagnetic relays according to the preamble of claim 1.
  • the invention has for its object to provide a contact spring arrangement of the type mentioned, in which, in the case of contact welding, there is no significant deflection of the contact spring due to the action of the armature to open the contact, while a deflection of the contact spring is ensured when contact is made .
  • this contact spring arrangement is particularly important in the case of polarized relays in which the actuating force of the armature increases progressively with increasing deflection from a permanent magnetic zero force zone up to the final tightening force and is reduced by the spring force of the contact spring.
  • the long spring travel favors good reproducibility of the storage of the permanent magnetic force in the contact springs, so that the desired contact force can be set in a narrow range.
  • this movable mounting does not allow a secure electrical connection between the contact spring and its connection, so that the arrangement is hardly usable in practice. If, on the other hand, one would connect the contact spring with its connection in the known arrangement, for example by welding or soldering, the two arms of the contact spring would be movable independently of one another, so that the above-mentioned a characteristic feature of the invention would no longer be fulfilled.
  • Notches 14 extending in the longitudinal direction of the spring are divided into three sections 1 ', 1 ", 1'” and fastened to a connector 3 at their other end. These sections are spread apart and biased against each other by the actuating pieces 6, 7 in such a way that contacting begins with a force F K.
  • the two outer sections 1 ', 1'"run essentially in the longitudinal direction of the spring, are covered with contact material 4 in the areas opposite a fixed contact 5 and have their ends attached to the second actuating piece 6.
  • the middle resilient section 1 is used to achieve one Preload F K is offset relative to the two outer sections 1 ', 1 "', guided essentially parallel to them and supported at the end on the first actuating piece 7 of the actuating part 12.
  • the resilient distance which is decisive for the closing of the contact 4, 5 results from the sum the distance L 1 from the point of application of the first actuating piece 7 to the base 15 of the resilient section 1 'on the contact spring 1 and the distance L 2 from the base 15 to the contact point.
  • the contact 1 is actuated via the actuating part 12 by an armature (not shown) in the direction of arrow 16.
  • the actuating piece 7 presses against the end of the resilient section 1 "and brings the contacts 4 into engagement with the fixed contact 5.
  • the contact begins according to the preload of the resilient section 1 "with the initial contact force F K , the contact is characterized by special low bounce.
  • the resilient length L 1 + L 2 is effective.
  • the resulting large spring travel provides a good possibility for storing this force in the contact spring 1 in the event that the actuating force of the armature is obtained from the attraction force of a permanent magnet.
  • This stored force determines the contact force.
  • the actuating piece 6 presses against the sections 1 ', 1'''. Since the distance L 3 from the point of application of the actuator 6 to the contact is as short as possible, the deflection of the sections 1 ', 1 m is relatively small, so that the contact opening is forced.
  • stiffening profiles 13 can also be embossed into them.
  • a fixed contact 5, 5 ' is provided on both sides in the region of the free spring end, which are offset from one another in the longitudinal direction of the spring.
  • the actuating pieces 6, 7 are each arranged in the immediate vicinity of the fixed contacts 5, 5 ', in such a way that to close a contact 5, 4 or 5', 4 'a larger resilient distance L 2 or L2 from the point of application of the actuating piece 6, 7 to the respective contact point is present as the distance L 3 or L 3 ′ which is decisive for opening the contacts from the point of application of the actuating piece 7, 6 to the respective contact point.
  • a changeover contact is realized in a simple manner, in which the contact via the long spring travel L 2 , L2, on the other hand, is forced via the short and thus rigid sections L 3 , L 3 , '.
  • a profile 13 can also be stamped into the spring 1 in this exemplary embodiment.
  • the contact spring 1 is actuated, for example, via the rotating armature 8, which is partially shown.
  • the first actuating piece 7 engages between the attachment point of the contact spring 1 at the connection 3 and the fixed contact 5 'located closer to the connection 3 in the immediate vicinity of this first fixed contact 5' and the second actuating piece 6 at the fixed contact 5 which is more distant from the connection 3 extended free end of the contact spring 1 in the immediate vicinity of this second fixed contact 5.
  • the actuation of this contact 4, 5 takes place in the position shown via the actuating piece 7, which acts with the force F on the spring.
  • Fig. 3 shows a rotary armature relay with a changeover contact 17, a normally open contact 18 and a normally closed contact 19, which are actuated by actuating pieces 6, 7 of an actuating part 12 by the rotary armature 8.
  • the rotary armature also contains permanent magnets M and two pole shoes 9, 9 ', which interact with pole ends 10, 10' of the coil core.
  • a single fixed contact 5 is provided in the region of the free spring end.
  • the first actuating piece 7 engages between the attachment point of the contact spring at the connection 3 and the contact point on the side of the contact spring 1 facing away from the fixed contact 5 and the second actuating piece 6 at the end of the contact spring 1 which is extended beyond the fixed contact 5 in the immediate vicinity of the fixed contact 5 and on the side of the contact spring facing this contact.
  • the Actuating part 12 is also designed such that the points of attack of all actuating pieces 6, 7 lying on one side of the armature 8 lie in one plane.
  • FIG. 4 shows a relay with four changeover contacts 20, 21, 22, 23, which in principle correspond to the changeover contact in FIG. 2.
  • the magnet system essentially corresponds to that shown in FIG. 3, so that the same details are provided with the same reference numerals.
  • a straight contact spring 1 is arranged between offset fixed contacts 5, 5 '
  • the connections 3 of the changeover contact springs 20, 21, 22, 23 and the fixed contacts 5, 5' are arranged in a line, whereby the contact springs between these fixed contacts are passed in an offset.
  • the storage of the permanent magnetic force also includes the possibility of additionally compensating for the temperature coefficient of the coil.
  • permanent magnets M are to be provided, in which the influence of the temperature coefficient on the actuating force of the armature due to the storage effect of the contact springs is greater than on the permanent magnetic field. For example, this can be achieved with BaOFe magnets.
  • the contact 4, 5 is opened when the end of the rotary armature 8 moves in the direction of the arrow 16, as in the examples described above. In the event that the contact 4, 5 is welded and the actuating force F of the armature 8 is not sufficient to break the weld, this armature movement does not take place. The existing switching state is then retained for all contacts 4, 5 and 4 ', 5'.
  • FIG. 5 shows a rotary armature relay, in which an armature provided with permanent magnets is supported on one side on a flexible web 24 in a bearing block 25.
  • the insulating material jacket also fixes at least one permanent magnet (not shown) and pole shoes 9, 9 'in the armature, which interact with the pole ends 10, 10' of the coil core.
  • the actuating pieces 6, 7 and 6 ', 7' shown in section are connected to one another at their upper side, that is to say they grip around the contact springs 1 and 1 '.
  • the right contact 4, 5 is closed, the left contact 4 ', 5' is open.
  • the crowned actuation piece 7 presses against the contact spring 1, while the opposite actuation piece 6 is lifted off the latter.
  • the contact spring 1 experiences considerable deflection.
  • the contact opening at the left contact point 4 ', 5' takes place through the action of the actuating piece 6 'on the contact spring 1', the actuating piece 7 'being lifted off the contact spring.
  • the contact-near corner 26, 26 'of the actuating piece 6, 6' comes into engagement with the contact spring 1 ', so that only the short resilient length L 3 , L 3 ' is effective up to the contact point.
  • the contact point on the contact spring moves with increasing opening of the contact 4 ', 5', since the surface of the actuating piece 6 'facing the contact spring 1' runs parallel to the longitudinal axis of the armature 8, from the contact-near to the non-contact corner of the actuating piece 6 '.
  • This also ensures in this embodiment of the invention that the contact is made over long spring travel L 2 , L 2 ', but the opening takes place over short and thus rigid sections L 3 , L 3 '.
  • the permanent magnetic attraction force can be stored well in the contact springs 1, 1 '.
  • FIG. 6 shows a permanent magnet armature 8 of a polarized relay with a magnet M between the pole shoes 9, 9 ', which is mounted in its axis of gravity A and is located in one of two rest positions.
  • the magnet M is partially encased in a known manner by plastic of the actuating part 12 and thus fixed.
  • Armature 8 and actuating part 12 with the actuating pieces 6, 7, 6 ', 7' formed thereon form a unit.
  • the arrangement according to FIG. 6 is a mirror image of both the Z and Y axes and is therefore not shown in full.
  • the armature 8 is in one of its two end positions, the pole piece 9 ′, after an armature path s, with the force F 4 comes to rest on one of the pole ends 10, 10 'of a coil core, not shown.
  • To the side of the X axis of the armature 8 are the fixed contacts 5, 5 'and in the center thereof the contact connection 3, to which the contact springs 1, 2' are also firmly connected in the center.
  • the contact spring 1 is provided with contacts 4, 4'.
  • the contact spring 2 In addition to the contact spring 1 functioning as a changeover switch, the contact spring 2 'runs. Both springs have a small preload F K (Fig.
  • this double contact spring is the branching of the contact current. A part of this current flows, as usual, from the contact point 4 ', 5' via the contact spring 1 and the rest from the contact spring 1 in the opposite direction via the contact parts K and the spring 2 'to the contact connection 3.
  • the permissible current load for the double contact spring according to the invention is even higher because its total surface area is approximately twice as large as that of a single spring with corresponding suspension properties. As a result, both the heat dissipation is improved and the line resistance at high-frequency currents is reduced due to the skin effect.
  • the widths of the springs can also be varied in order to achieve the desired spring properties or stiffness of the contact springs used. In contrast to a change in spring length and thickness, a change in width only has a linear effect on the deflection of the contact springs.
  • the spring constant in the deflection range x (Fig. 9) should rise very low and moderately steep in the subsequent contacting range, both for reasons of adequate storage of permanent magnetic attraction forces for the contact force and because the response and dropout values of the relay are as stable as possible. This should also be ensured if the contact distance increases as a result of contact erosion.
  • the spring constant must rise very steeply in the case of a forced contact opening, that is to say the spring piece acting thereby must be rigid. For this reason, the resilient length L 2 from the contact point 4 ', 5' to the actuator 6 'is kept as short as possible.
  • a forced contact opening can be obtained by either stamping a profile 13 (FIG. 11) for the contact spring 1 or, which is equivalent, a larger one Thickness h is chosen as it is given for the thickness h 'of the more flexible contact spring 2. This is problem-free because, after the contact has opened, the relatively large spring length L 5 with a very low spring constant is effective.
  • Fig. 7 shows an embodiment of the invention with two also arranged laterally to the X axis of the armature not shown working contacts, which are closed when the armature is deflected about its axis of rotation A in the direction of the arrow, according to the above-mentioned description.
  • the exemplary embodiment shows a further possibility of making the spring 2 'even more flexible compared to the contact spring 1, in that, in addition to the relation of the spring strengths h: h', that of the lengths L 6 : L 7 can also be varied by the two contact springs 1, 2 'are attached to differently positioned contact connections 3, 3'. These connections can either be connected externally or remain separate.
  • this second contact connection 3 'offers better adjustment options, which are also given when the two contact connections 3, 3' are fork-shaped, combine in a known manner in the plastic carrier part and emerge from the base of the relay as a single connecting pin.
  • two normally closed contacts are designed either on the other side of the X-axis or the subordinate one as such with an analog force-displacement curve and corresponding geometry.
  • the two contact spring members 1, 2 are formed from a spring band, provided with contacts 4, 4 ', which are arranged opposite the fixed contacts 5, 5', in the center firmly connected to the contact terminal 3 and are symmetrical to each other with respect to the X-axis.
  • the two spring members of this double contact spring are also located just next to the contacts 4, 5 and 4 ', 5' with a low preload F K on the actuating pieces 6, 7, which are made of plastic and are integrally formed on the armature 8.
  • the contact distance x given during the switching process is expanded by the deflection spring travel f in addition to the given geometric relations.
  • Fig. 10 shows an embodiment according to the principle of Fig. 9 but with two changeover contacts arranged next to each other on one end of the relay, and since the opposite end can be equipped with both the same arrangement according to Fig. 8 and Fig. 10, so the possibilities set out in a polarized relay to create 2, 3 or 4 changeover contacts with the double contact spring according to the invention and to position all contacts 4, 5, 4 ', 5', very close to the pivot axis X, thereby causing the abrasion of the actuating pieces 6, 7 is correspondingly low compared to the contacts to be actuated.
  • 11 and 12 show contact spring arrangements in which the contact point K of the contact springs 1, 2, 2 'is predetermined by a bead.
  • the springs 1, 2 being attached on one side to the connection 3 and being electrically connected to one another.
  • the actuating piece 7 presses the contact spring 2 to the left until the contact 4 of the spring 1 comes into engagement with the fixed contact 5.
  • the springs 1, 2 are pretensioned relative to the actuating pieces 6, 7, the contact is made with a corresponding initial contact force F K.
  • the spring force F 1 transmitted to the contact point via the bead of the spring 2 is added to this initial contact force (FIG. 13).
  • the resilient length L 1 of the contact spring 2 is primarily decisive for storing the contact force F 3 obtained from the permanent magnetic attraction force M '.
  • the arrangement according to FIG. 12 is designed as a changeover contact, the actuation of both contacts 4, 5 and 4 ', 5' taking place in the same way as for the contact shown in FIG. 11. For this reason, matching reference numerals have been chosen.
  • the contact spring 1, 2 is formed in one piece, fixed in the center on a connecting pin and provided on both sides with two resilient sections. The sections running side by side are connected to each other on both sides of the connecting pin 3 by webs 11. The contact spring 1, 2 is thus a stamped and bent part that z. B. is positioned by spot welding through the two webs on the connecting pin 3.
  • the curve M 'progressively rising and dashed from the center 0 represents the permanent magnetic attraction force without excitation power acting on the pole shoes 9, 9' of the armature 8 during the armature path s.
  • the illustrated advance of the permanent magnetic attraction force M ' which is symmetrical with respect to the axis Z, is useful if bistable switching behavior, ie two-sided contact rest position is desired.
  • the axis Z can also be shifted from the center of the anchor path, e.g. B. if asymmetrical, one-sided contact resting position should be achieved. This can be achieved, for example, by differently sized pole faces 9, 9 '.
  • the force-displacement curve M ' is counteracted individually and in its entirety by the forces of the contact spring members 1, 2 or 2' according to the dotted lines D.
  • the force F acting on the springs 1, 2 or 2 'from the actuating pieces 6 or 7 is distributed to a lesser extent F 2 to the contact connection 3, 3' and to a greater extent F 3 via the contact point K
  • Springs 1, 2 or 2 'on contacts 4, 5 or 4', 5 ' The opposing forces of the springs are insignificant during the contact path x.
  • the invention thus also helps the compensation of temperature influences proposed for modern relay technology in US Pat. No. 3,634,793 in order to achieve a constant response voltage and the use of a so-called C circuit for breakdown.
  • Such a circuit, with which bistable relays are given monostable switching behavior, is e.g. B. in the "Relay Lexicon", 1975 by H. Sauer, page 12, or the magazine “Elektrotechnik", 60, H. 24, 27.12.78. Page 43.
