Definitions

  • the invention relates to an electromagnetic switching relay, which has two separately controllable coils for switching at least one contact unit on an insulating base body.
  • the invention relates to a polarity reversal relay for controlling electrical drives with reversible direction of rotation, such as DC motors for clockwise and counterclockwise rotation, as are used in motor vehicles.
  • a pole-reversal relay is already known for the application mentioned (DE 38 43 359 C2), in which two complete relay blocks are arranged point-symmetrically on a common base body.
  • the contact elements belonging to the respective relay blocks and actuated by the two armatures lie between the relay blocks and are at least partially assigned to both systems via fixed connections. Since this known system for each of the two relay blocks each has its own coil form, its own yoke and its own armature, all of which are accommodated on the base body, it requires a correspondingly high amount of individual parts, which in turn not only means increased production and assembly costs , but also requires an increased volume of the relay system.
  • DE 31 24 412 C1 also discloses a polarized small relay with two windings connected in series, in which a single armature is arranged and switchable in the middle between the two coil cores is. Apart from the fact that this relay requires a permanent magnet system, it is not suitable for the purposes mentioned above, since the armature itself, which serves as a contact element, can neither switch large currents nor enables the number of contact combinations required, for example, to reverse the motor.
  • a switching relay for transmission technology and electronics in which two magnetic coils are arranged with their core axes aligned with one another on a base plate, between the mutually facing inner core ends of which an armature can be switched.
  • this armature is mounted there far outside the coil area and carries contact elements at the ends facing away from the coils.
  • the armature actuates further contact springs arranged outside the coil area via a lever device.
  • the entire structure of the relay described there is very complicated and voluminous by today's standards, so that this construction is out of the question for use in a motor vehicle.
  • the aim of the invention is to provide an electromagnetic changeover relay which can be used in particular as a polarity reversal relay and which enables a compact structure with a few simple parts.
  • the relay according to the invention therefore has only a single yoke that connects the outer ends of the coil cores, and, in a preferred embodiment, it only needs a single armature that can be switched between the inner core ends.
  • This armature actuates contact springs, which are each arranged in the area between armature and coil, an overlap of the contact springs with the respective coil core being avoided, of course, by appropriate cross-sectional design of the springs.
  • a particularly simple manufacture with particularly few parts is obtained if the two coil formers for receiving the windings are formed in one piece on the base body itself, so that both windings can also be applied to the base body in one operation. Subsequent alignment of the two systems with one another is therefore not necessary.
  • both contact springs each fastened to a holding pin of the base body, rest on a common center contact element in the idle state, while when one or the other coil system is excited via the armature, one or the other contact spring is optionally connected to one is switched by two external contact elements, which external contact elements can in turn be connected to one another and provided with a common connecting pin.
  • two external contact elements which external contact elements can in turn be connected to one another and provided with a common connecting pin.
  • the contact springs themselves can be non-positively fastened by plugging them onto their associated holding pins provided with connecting pins, with extensions being able to support the base body for the purpose of pretensioning.
  • the above-described arrangement of a holding pin for a contact spring in the area between the armature and coil can influence the function of the relay insofar as via the contact spring with a holding pin serving as a connecting pin and the counter-contact element when the contact is closed, one through the iron circle of core, yoke and armature guided current loop can be formed, the magnetic field of which overlaps the excitation circuit of the coil. Depending on the direction of flow in this current loop, this can additionally generated magnetic flux to be directed in the same direction or in opposite directions to the excitation flux and thus strengthen or weaken the attraction force on the armature.
  • the retaining pin of the other contact spring as a connecting pin. So this additional pin can be used instead of the opposite pin or in addition to this for guiding the load current.
  • the holding pin can also be used as a connecting pin for both contact springs. If, on the other hand, it is desired that the loop effect is only partially effective, the retaining pin of this other contact spring can be connected in parallel to the separate connecting pin connected to it, so that half of the load current flows over both pins. The loop effect is then only about half of the loop current effect when the full load current is conducted via the relevant bearing pin.
  • a U-shaped connecting bracket is fastened across the armature with both ends in the base body, a first leg forming the connecting pin and a second leg forming a retaining pin for the contact spring connected to the connecting pin.
  • This U-shaped connection bracket is expediently plugged into the base body, while the separate connection and retaining pin of the former contact spring can be embedded in the base body.
  • the undesirable effect of a current loop in the magnetic circuit of the relay due to the parts carrying the load current can also be avoided by a configuration in which the U-shaped yoke with its side legs is perpendicular to the base plane and with its central section lying parallel to the base plane above the two coils, the anchor being arranged approximately perpendicular to the base plane in the air gap between the inner core ends.
  • This relay preferably has at least two contact springs, which are arranged between the armature and one of the coils and are hairpin-shaped in the vicinity of the armature bearing point, of which one connecting leg is anchored in the base body and forms a connecting pin perpendicular to the base plane, and of which the second pin Leg can be switched between a rest position and a working position by the anchor.
  • connection pins led out downwards that no current loop passing through the magnetic circuit of the relay is formed via the contact springs carrying the load current and their connections. This also eliminates a magnetic influence on the armature by the load current.
  • the hairpins bent contact springs can rest with their curvature on retaining pins, which in turn are fastened in the base body, but do not serve as connecting pins. But it is also possible to get by without such holding pins.
  • the respective contact spring with its connecting leg in one Slot of the base body fastened by clamping Furthermore, it is expedient to fold the connecting leg at least in the section forming the connecting pin, but possibly also in the section serving for clamping, in order to double the cross section in these areas.
  • the relay shown in Figures 1 to 4 has a base body 1, which has two integrally connected coil bodies 2 and 3 and a contact space 4 formed between the two coil bodies.
  • a winding 23 is applied to the bobbin 2 between two flanges 21 and 22, and a winding 33 is applied to the bobbin 3 between flanges 31 and 32.
  • Two connecting pins 24 and 25 for the winding 23 are embedded in the coil flange 21, and two connecting pins 34 and 35 for the winding 33 are embedded in the coil flange 31. In this way, both windings can be controlled and excited separately. Since the two bobbins are in one piece parts of the base body, the two windings can be produced in one operation on a winding machine.
  • a U-shaped contact plate 5 is fastened by insertion, which forms two external contact elements 51 and 52 in one piece and is guided through the bottom of the base body with a connecting pin 53.
  • Another contact plate 6 forms a center contact element 61 and a connecting pin 62 which is guided through the bottom of the base body.
  • the external contact elements 51 and 52 are each provided with a contact piece, and the center contact element 61 is provided with two contact pieces.
  • two contact springs 7 and 8, which consist of leaf spring material, are arranged in the contact chamber 4.
  • Each contact spring is bent at an attachment end to form an adapter sleeve 71 or 81 and is attached with this adapter sleeve to a holding pin 9 or 10 with an extension serving as a connecting pin 9a or 10a.
  • the contact springs each form contact-making ends 72 and 82, which are each provided with contact pieces on both sides and can be switched between the center contact element 61 and a respective counter-contact element 51 or 52.
  • both contact springs 7 and 8 are biased towards the center contact element 61. Even with a switching movement of the contact springs, there is no rotation on the holding pins 9 or 10. In some cases, however, it could be necessary to fasten the contact springs on the holding pins by additional means, such as soldering or welding. In this case, the fastening end of the springs could also be shaped differently.
  • the contact springs 7 and 8 each have an extension 73 and 83 at their connection end, which is supported on the base body, namely on the respective coil flange 22 and 32, and thus brings about the aforementioned preloading of the contact springs towards the center contact element 61.
  • the bias of the contact springs can be generated in any case during assembly, even if the springs are to be subsequently fixed to the connecting pin by welding or the like.
  • the contact springs 7 and 8 have in their Middle part each have a circular section, e.g. B. 84, which is adapted to the rounding of the associated coil core and enables free movement of the contact spring above the coil core.
  • a yoke-armature assembly is placed on the bobbin provided with windings and contact elements, which is shown in perspective in FIG. 2 before assembly.
  • a yoke 12 with two side sections 121 and 122 and an elongated central section 123 is pushed onto the two outer coil flanges 21 and 31.
  • an armature 13 is mounted on the yoke 12, which has holding tabs 131 and 132 at its end of the bearing in an extension of its side edges. These retaining tabs are each bent into bearing notches 124 and 125 when the armature is mounted on the yoke middle section 123 and thus prevent the armature from falling out.
  • the storage of the armature is expediently designed as shown in two detail sections of FIGS. 8 and 9.
  • the inner wall 129 of the respective bearing notch 124, on which the retaining tab 131 rolls, is crowned.
  • the yoke section 130 facing the armature is also crowned, so that the armature can roll on it with its bearing edge.
  • This section 130 can be embossed in whole or in part over the yoke width.
  • the armature can also be crowned on its end face 139 facing the yoke.
  • the yoke 12 After mounting the anchor, the yoke 12 is on the Basic body plugged on, so that the side legs 121 and 122 engage in corresponding recesses 26 and 36 of the flanges 21 and 31 and the armature projects into the contact space.
  • centering pins 11 are also formed on the base body and engage in openings 128 when the yoke 12 is assembled. Thereafter, two cores 14 and 15 are pressed from the outer sides through recesses 126 and 127 of the yoke side legs 121 and 122 into axial recesses 27 and 37 of the two bobbins and by press fitting or in another way, for example, notching or welding, with the yoke connected.
  • the working air gap to the two anchor surfaces is adjusted by pressing in the cores 14 and 15 with dimensional accuracy.
  • the armature 13 is provided on each of its side faces with a bevel 133 in order to be parallel to the inner pole face 141 or 151 of the respective core when switching.
  • a bevel 133 instead of the bevels 133 on the armature, it would also be conceivable to make the core pole surfaces 141 or 151 somewhat oblique or to arrange the coils with the respective cores slightly obliquely to one another.
  • Switch cams 134 are also formed on both sides of the armature and are used to actuate the contact springs 7 and 8.
  • the thickness of the armature between the two switching cams is chosen to be so small that the armature is decoupled with play between the two contact springs 7 and 8 when the latter both contact the center contact element 61 with their contacting ends 72 and 82.
  • a thicker armature and a corresponding spring preload it would also be possible to have only one contact spring rest on the central contact element in the idle state and thus create, for example, a follow-up contact.
  • both contact springs 7 and 8 rest with their contacting ends 72 and 82 on the center contact element 61.
  • the armature is attracted to the associated core 14 or 15, whereby it brings the associated contact spring 7 or 8 into contact with the corresponding external contact element 51 or 52.
  • the respective other contact spring remains on the center contact element 61.
  • the armature passes through a central position in which both contact springs 7 and 8 simultaneously make contact with the central contact element 61 before the other contact spring is then switched on to the associated external contact element 52 or 51. If none of the windings is energized, the armature remains in the middle position and the contact springs 7 and 8 lie on the center contact element 61 with their pretension.
  • FIG. 5 shows a preferred circuit diagram for use as a polarity reversal relay for controlling a direct current motor M, the connections and the contact elements being designated as in FIGS. 1 to 4.
  • the DC motor M is coupled to the pins 9a and 10a of the contact springs.
  • the connection pins 53 and 62 of the mating contact elements 5 and 6 are connected to a current source (+ or -).
  • the armature actuates one of the contact springs 7 and 8 with a switching cam, the direct current motor M being connected to the second pole of the power source with the actuated contact spring via the make contact element 5, so that the motor starts up in one of the directions of rotation depending on the polarity.
  • connection pins are indicated with dashed lines for such an installation position, that is to say the connection pins 9b, 10b, 62a and 53a for the contact elements and the coil connection pins 24a, 25a, 34a and 35a.
  • the relay is provided with a housing cap, not shown, and sealed on its underside, for example in a conventional manner with a base plate, the open columns of which are cast.
  • FIG. 6 shows a modified embodiment of the contact system in a representation corresponding to FIG. 1.
  • contact springs 17 and 18 are each firmly connected to the armature in the vicinity of the bearing point via insulating intermediate layers 19. The contact springs are thus taken directly by the armature movement; the armature therefore does not require switching cams as in the previous exemplary embodiment.
  • the contact springs 17 and 18 are Connected via flexible connecting lines, for example via strands 20, to the associated connecting pin 9a or 10a.
  • the fixed connection of the contact springs to the armature according to FIG. 6 has the result that when the armature is switched to one side, for example when the contact spring 18 is switched to the external contact element 52, the other contact spring, for example 17, with increased contact force to the center contact element 61 is pressed. This can be advantageous for certain applications.
  • Figure 6 shows a further modification compared to Figure 1 in the type of anchor bearing.
  • the armature is held by a bearing plate 30 which surrounds the central section 123 in a U-shape.
  • Bearing lugs 135 of the armature snap into corresponding recesses 38 in the bearing plate 30 and thus hold the armature.
  • This type of anchor mounting can also be used in the embodiment of FIG. 1 or 7, regardless of the type of contact spring attachment.
  • the various installation positions mentioned above can be combined as desired with the type of anchor bearing or the contact spring attachment.
  • FIG. 7 shows, in a further modification of FIG. 1, an exemplary embodiment with two armatures 137 and 138, which are arranged between the two coil formers 2 and 3 or the windings 23 and 33 and are mounted on a yoke 120.
  • This yoke 120 like the rest of the relay structure, largely corresponds to the construction of FIG. 1; it only has two pairs of bearing notches 124 and 125 for the two anchors, in which the two anchors are mounted as in the first exemplary embodiment.
  • An anchor bearing according to FIG. 6 would also be possible.
  • the structure of the two anchors 137 and 138 itself corresponds to that of anchor 13. But there each armature actuates only one contact spring 7 or 8, each requires only one switching cam 134 on the side facing the contact spring.
  • each armature independently actuates its own changeover contact, each with an inner contact element 57 or 58 and an outer contact element 67 or 68.
  • other contact configurations would also be conceivable.
  • the holding or connecting pins for the contact springs and for the coil windings are injected into the base body and are thus already positioned in the correct position without additional effort.
  • an additional connection pin 110 is provided in the area between the armature 13 and the coil winding 33, which connects the armature via a bracket section 111 overlaps and is connected to the retaining pin 9 of the contact spring 7.
  • the connecting pin 110 forms with the bracket section 111 and the holding pin 9 a U-shaped connecting bracket, which is fastened in the base body by insertion.
  • a connecting pin 110 and a holding pin 9 as well as the holding and connecting pin 10 and 10a in the base body by embedding and to bend a bracket section 111 over the anchor and to weld or otherwise fasten it to the opposite part.
  • the switching current I flows in the two contact springs and in their connecting pins in the opposite direction. Since the two connecting pins 10a and 110 lie on one side of the armature in the iron circuit of the winding 33, their respective current loop effects essentially cancel each other out, while in the iron circuit of the winding 23 there is no current loop effect as long as the holding pin 9 does not carry the switching current. However, if a current loop effect is to be produced in a targeted manner, the holding pin 9 can also be used as a connecting pin instead of the pin 110. It is particularly conceivable to connect both pins 9 and 110 in parallel outside the relay and thus to conduct half of the switching current through each of the pins. This current division results in a loop effect of approximately 50% compared to the full loop effect, which can be advantageous in certain load cases, for example lamp loads.
  • the relay shown in Figure 12 in turn has in principle the same structure as that of Figure 1 with a base body 1, which carries the windings 23 and 33 with their pins 24, 25 and 34, 35 and the yoke 12 and the armature 13.
  • a contact space 104 is designed in the lower region of the base body 1 so that it is open to the underside.
  • the mating contact elements 52 and 61 with their connecting pins 53 and 62 are inserted into the base body from below.
  • contact springs 107 and 108 are designed so that they can be attached from below to the retaining pins 9 and 10 with the connecting pins 9a and 10a. The contact springs thus extend below the coil cores 14 and 15, so that the load circuit from the connecting pins 9a and 10a via the contact springs 107 and 108 to the mating contact elements 51, 52 and 61 does not penetrate the magnetic circuit.
  • the relays shown in FIGS. 13 to 16 each have a structure similar to FIG. 1, the same reference numerals being assigned to the same parts.
  • two free-standing external contact elements 351 and 352 and a center contact element 361 are fastened, their associated connecting pins 353 and 362 being guided through the base 301 perpendicular to the base plane.
  • the center contact element 361 is inserted into a slot 302 of the base body from the front side visible in FIG. 13, while the external contact element 351, like the external contact element 352 not visible in FIG. 16, is in each case from the opposite rear side a corresponding base body slot 303 is inserted.
  • the two external contact elements 351 and 352 could also be connected to a common counter-contact element and provided with a single pin.
  • the contact space 4 between the two coil flanges 22 and 32 there are also two contact springs 307 or. 308 arranged, which are each switchable between an external contact element 351 or 352 and the center contact element 361.
  • These two contact springs 307 and 308 are bent in a hairpin shape and thus form an approximately perpendicular to the base plane connecting leg 309 and 310, which is then guided outwards in a connecting pin 311 and 312, respectively.
  • the bending section 313 or 314 of the contact springs is in each case designed as an adapter sleeve and is fitted onto a holding pin 315 or 316. These retaining pins are anchored in the base body, but are not designed as connecting pins.
  • contact springs 317 and 317 are provided, which are also bent in the shape of a hairpin and each form a connecting leg 319 or 320 with integrally formed connecting pins 321 or 322.
  • the bending area 323 or 324 is made simpler in this case since there are no retaining pins.
  • the contact springs 317 and 318 are fastened by clamping in fastening slots 304 and 305 of the base body.
  • the connecting legs 319 and 320 are each folded in the longitudinal direction or transversely, so that the double cross section of the spring plate comes into effect.
  • the connecting legs 309 and 310 in FIG. 13 are also folded; at least in the area of the connecting pins 311 and 312, such a folding is very expedient in order to achieve the desired stability.
  • the contact springs are each shown broken off in FIGS. 13 and 14 in the region of the connecting legs in order to make the fixed contact elements behind them visible. Otherwise, the shape of the contact springs can be seen from FIGS. 15 and 16. From this it can also be seen how the contact springs are adapted in their contours to the coil core 14 or 15 so as not to impair the air gap between the respective core and an armature 13 to be described.
  • the contact springs with their connecting legs are each inserted into lateral slots 306 from the front side shown in FIG. 13 or FIG. 14.
  • an embodiment would also be conceivable in which the contact springs as well as the fixed counter-contact elements are inserted into corresponding openings in the floor 301 from above perpendicular to the base plane.
  • the coil connection pins 24 and 25 or 34 and 35 are each embedded in a coil flange 2 or 3 and bent perpendicularly to the base plane on the invisible rear side of FIG. 13 or FIG. 2.
  • the contact springs arranged between the armature and the coil are led out vertically downward with their associated connecting leg, they do not form a load current loop which would penetrate the iron circuit of the core, yoke and armature. In this way it is ensured that even a high load current does not adversely affect the attraction behavior or fall behavior of the armature.
  • FIG. 13 where the holding pins 315 and 316 are also anchored in the base body. Because these retaining pins only serve to hold the contact springs and have no connection elements, so that they also do not carry the load current. Since the pins 311 and 312 or 321 and 322 directly on the respective Contact spring are molded, can also ensure a low-resistance current transfer from the contact springs to the respective connection points in a conductor track.
