Definitions

  • the invention also relates to a method for producing such a relay.
  • a relay of the type described above is known for example from EP 0 423 834 A2.
  • the various assemblies i.e. the base with the fixed contact elements, the armature with the movable ones Contact elements and the coil assembly are arranged one above the other in a layered construction, which leads to a summation of the manufacturing tolerances of the individual parts.
  • the armature is fastened by means of bearing elements, which are fastened in the form of torsion bars and fastening arms lying parallel to the base plane, on support surfaces also lying parallel to the base plane.
  • the distances between the fixed contact elements and the movable contact elements connected to the armature are thus predetermined by the manufacture of the individual parts. This means that, on the one hand, the individual parts have to be manufactured with very little tolerance and thus are expensive, but that the remaining tolerances still add up during assembly. Subsequent adjustment of the contact spacing is therefore unavoidable and is also provided in the known relay by bending the fastening tabs.
  • the aim of the present invention is to construct a relay of the type mentioned at the outset in such a way and to specify a manufacturing or assembly method for this that the tolerances of the individual parts have no influence on the contact spacings. Regardless of the accuracy of the individual parts, the movable and the fixed contact elements of the relay should be able to be mounted in the correct position relative to one another, so that subsequent adjustment is no longer necessary.
  • this goal is achieved in a relay of the type mentioned at the outset in that the bearing elements are designed as flat bearing strips which extend at least with one fastening section perpendicular to the base plane and in that the bearing supports form vertical contact surfaces against which the fastening sections of the bearing belts lie flat, and are attached in an infinitely adjustable height position.
  • the previous layer construction is thus abandoned, and the connection between The moving parts and the fixed base take place in connection planes which run perpendicular to the base plane and thus in the direction of the switching movement.
  • the two bearing strips each extend with an elastic section next to the armature such that the tangential plane at each point of this section is parallel to the axis of rotation of the armature, so that the elastic section is practically only subjected to bending during the armature movement.
  • the bearing strips are each embedded in lateral extensions of the insulating material carrier in such a way that they emerge from it in a direction parallel to the longitudinal direction of the armature and are bent in a direction perpendicular to the base plane and are fastened to the parallel mounting tabs of the bearing supports.
  • the two bearing strips preferably extend in a common direction perpendicular to the longitudinal axis of the anchor in such a way that they are subjected to simple bending when the anchor moves. If the bearing strips also serve as a power supply to the movable contact elements, then they are each connected to at least one of these movable contact elements, preferably in one piece, while the bearing supports are in turn connected to connection elements in the base.
  • the end section of the respective bearing band is clamped between the associated bearing support and an opposing clamping plate, which defines with one end edge a clamping point for the bearing band in front of its fastening point.
  • the clamping plate can by a Be formed in a U-shaped bent end portion of the bearing support, which engages around the end portion of the bearing band at its end edge or laterally.
  • the bending section between the actual bearing support and the clamping plate can be weakened in cross section, for example by embossing to reduce the thickness and / or lateral incisions to reduce the width.
  • the clamping plate it is also possible for the clamping plate to be part of a U-shaped clamp which is placed on the free ends of the bearing support and the bearing band.
  • the bearing band attached to it is clamped between the end edge of this clamping plate and the actual bearing support, so that this clamping point also forms the bending point for the respective bearing band during the anchor movement.
  • the actual fastening point which is preferably designed as a welding point, is thus completely relieved of the movement forces.
  • Another way to relieve the mounting point which is usually a spot weld, may be that the bearing band is arranged with the elastic section between the anchor and the bearing support and with an additional attachment section at the end or laterally formed on the bearing support a side of the bearing support facing away from the elastic section is attached. In this case, an edge of the bearing support lies between the welding point and the elastic section, so that the fastening point is again relieved.
  • the permanent magnet arrangement is preferably formed by a rod-shaped permanent magnet which is arranged parallel to the coil axis below the coil and at the ends poles of the same name and a pole of the same name in the middle.
  • the bearing strips are first pre-fixed after the adjustment of the contact distance by a welding spot on the bearing support, preferably by a laser welding point on the end edge of the bearing strap, and then an end section of the bearing support is used to form a clamping plate U -shaped over an end edge of the bearing band, the adjacent sections of the bearing support, the bearing band and the clamping plate are then welded together.
  • a welding spot is expediently generated using a laser welding process or a similar spot welding process in the edge region of the bearing belts and the bearing supports or clamping plates.
  • the relay shown in the drawing has a base 1 on which a contact arrangement 2 is movably mounted, which in turn is firmly connected to a rocker armature 3.
  • a flat permanent magnet 4 is arranged approximately parallel to it, which lies with a central pole (N) above the bearing point of the armature and has at its ends two poles (S) of the same name to the central pole.
  • a coil 5 is arranged above the permanent magnet and above the armature, into which a rod-shaped core 6 is inserted axially.
  • a pole piece 7 is connected to the ends of the core 6.
  • Each of the pole shoes 7 is also coupled to one end of the permanent magnet 4 in the region of a coil end and forms a pole surface for the armature 3 at the bottom.
  • the base 1 consists of a base base body 10, which is formed from insulating material and in which fixed mating contact elements 11, 12, 13 and 14 as well as connecting elements 15 and 16 for movable middle contact elements are anchored. All these contact elements are expediently cut out of a common circuit board and embedded in the base body with a fastening section parallel to the base surface of the base. From these embedded sections, connection pins, for example 11a, 12a and 15a, are bent perpendicular to the underside of the base.
  • the counter-contact elements 11, 12, 13 and 14 themselves are exposed at the top of the base in the trough-shaped base body 10 and are provided with welding profiles 11b, 12b, 13b and 14b.
  • connection elements 15 and 16 are bent upwards on opposite sides of the base, where they are replaced by corresponding Bends and offsets form two bearing supports 15b and 16b for the movable contact arrangement and for the armature.
  • a rib 17 is formed in each case between the fixed counter-contact elements 11 and 13 or 12 and 14 lying next to one another in order to enlarge the insulating distances.
  • the base body has a cutout 18 at the corners for plugging the coil 5.
  • vertical ribs 19 are formed on the vertical wall of the base body 10, the function of which will be described later.
  • the movable contact arrangement 2 has a contact carrier 20 made of insulating material, in which contact springs 21, 22, 23 and 24 are embedded. These contact springs optionally work together with the fixed counter-contact elements 11, 12, 13 and 14 located below them. To form two changeover contacts, the contact springs 21 and 22 are connected in one piece in the present example, so that they form a center contact element which is mechanically and electrically connected to the connecting element 15 in the base via a bearing band 25. Accordingly, the contact springs 23 and 24 are integrally connected to a bearing band 26 and coupled to the connecting element 16. The contact arrangement 2 is firmly connected to the armature 3 via two fastening pins 27.
  • the armature 3 consists of a flat iron strip 30, the central region of which is bent upwards to form a transverse bearing web 31.
  • the armature can roll on the permanent magnet 4 lying above it and optionally rest with one of its pole faces 32 or 33 on one of the pole shoes 7.
  • the bores 34 serve to receive the fastening pins 27 of the contact arrangement, which can be fixed in these bores by hot deformation.
  • the coil 5 has a coil former 50 made of insulating material, which carries a winding 57 between two flanges 51 and 52 and the rod-shaped core 6 in the coil former tube records.
  • the coil flanges 51 and 52 each have extensions 53 which extend downwards and which overlap the base 1 in a box-like manner and come to rest in the recesses 18 thereof.
  • transverse ribs 54 are formed in each case, which each lie in a cross shape with the longitudinal ribs 19 of the base and thus ensure a tight fit in any position.
  • Vertical grooves 55 are provided in the coil flanges 51 and 52 and in the extensions 53, into which coil connection elements 56 are inserted. In another embodiment, however, they could also be embedded in the material of the coil former.
  • the pole shoes 7 When assembling the coil assembly, the pole shoes 7 are inserted from below into corresponding channels of the coil body flanges 51 and 52, their fork-shaped ends 71 each encompassing the core 6 located in the coil body tube. However, it would also be conceivable to provide the pole shoes 7 with an opening which is closed at the top, in which case the pole shoes would then have to be plugged onto the core in the axial direction.
  • the movable contact arrangement 2 When installing the relay, the movable contact arrangement 2 is first combined with the armature 3 to form an armature-contact assembly, the fastening pins 27 being anchored in the bores 34 by hot deformation in the manner described above. Then this armature-contact assembly is connected to the base 1, the contact distances being set in a defined manner. This will now be explained in more detail with reference to FIGS. 4 to 7.
  • this carrier 20 has side lugs 28, from which the two bearing strips emerge in the longitudinal direction of the armature, from where they are then bent vertically upward with a relatively small radius.
  • These upwardly bent sections of the bearing strips thus lie in a common plane perpendicular to the base plane, which on the other hand also runs approximately through the bearing axis of the armature.
  • the bearing strips 25 and 26 are therefore not subjected to torsion, but only to a simple bend.
  • the ribs 17, against which the attachment 28 strikes in the event of impacts, serve as shock protection against the arm being deflected too far in its longitudinal direction.
  • the contact spacings 29 are set to predetermined, identical values. This is preferably done with a device according to FIG. 7 or with a comparable device.
  • the armature contact assembly with the contact springs 21, 22, 23 and 24 rests on the associated mating contact elements 11, 12, 13 and 14.
  • the bearing strips or connecting tabs 25 and 26 rest with their vertical contact surfaces on the bearing supports 15b and 16b of the connecting elements 15 and 16.
  • the mounting device 9 shown in Figure 7 contains a schematically shown measuring device 90, which is brought with two electrically conductive legs 91 and 92 to a coupling point on the top 35 of the armature (double arrow 95) until an electrical passage from the leg 91 over the armature to Leg 92 takes place and is determined in the measuring device mentioned. If the armature is crooked due to a deformed contact spring, a certain pressure force is required to establish the electrical continuity over the armature. The size of the deformation can be derived from the size of this necessary pressing force; if a maximum permissible predetermined force is exceeded, the anchor system is eliminated as faulty.
  • the measuring device travels down a predetermined path, that is to say toward the base 1.
  • a predetermined path that is to say toward the base 1.
  • an electrical connection is established between the four contact springs 21, 22, 23 and 24 on the one hand and the associated mating contact elements 11, 12, 13 and 14 in the base. This is determined by measurement on the connection pins 11a, 12a, 13a and 14a.
  • This test procedure ensures that at least one contact arm of the contact springs 21, 22, 23 and 24, each divided into two arms, ensures a sufficient overstroke.
  • the construction according to the invention thus enables a functional test to be carried out before the anchor assembly is attached; faulty assemblies can be eliminated early.
  • a slide 96 which is located in the measuring device 90, is lowered (double arrow direction 97).
  • the armature 3 is held by a permanent magnet 98 which is fastened on the slide 96.
  • the measuring device is now moved a way corresponding to the desired contact distance 29 (FIG. 6) - taking into account the overstroke - with the armature assembly (double arrow 95).
  • the bearing strips 25 and 26 of the armature-contact assembly are now at the desired height relative to the bearing supports 15b and 16b of the base assembly. In this position, the bearing strips 25 and 26 are welded to the adjacent bearing supports 15b and 16b, respectively.
  • the welding can be carried out, for example, as resistance welding or laser welding.
  • the magnet system the coil 5 with the core 6, the pole pieces 7 and the permanent magnet 4 is pushed onto the base assembly until the desired armature stroke is reached.
  • the coil body 50 clamps on the base body 10, the horizontal ribs 54 of the coil body on the vertical Ribs 19 of the base - if necessary together with other, not shown ribs on both parts - ensure the tight fit in any desired position.
  • both monostable and bistable switching properties of the relay can be achieved.
  • a monostable switching property can also be achieved by an additional separating plate (not shown), which is placed between one of the pole shoes 7 and the associated pole face 32 or 33 of the armature. After putting on the cap 8, the relay is sealed with casting resin in the base area.
