Definitions

  • the invention relates to an electromagnetic relay
  • a base made of insulating material, which defines a base plane with its bottom side and is anchored in the carrier for fixed contacts and contact connecting pins,
  • a relay of the type mentioned is described in WO 94/22156.
  • a coil body is placed directly on the base, which in addition to the coil winding and the core also carries the yokes and a permanent magnet and which is connected directly to the base in side areas.
  • a cap placed over the bobbin is connected to the base to form a closed housing.
  • This known structure is designed for conventional solder connection technology; however, the connection structure of the base and the coil former is not designed for greater mechanical or thermal loads.
  • relays should, if possible, also be designed to withstand the mechanical or thermal loads that occur with these techniques withstand without the precisely set characteristic values of the relay deteriorating.
  • SMT surface mounting technology
  • connection technology with press-in pins are increasingly desired for the assembly of printed circuit boards in addition to the conventional contacting via solder pins
  • relays should, if possible, also be designed to withstand the mechanical or thermal loads that occur with these techniques withstand without the precisely set characteristic values of the relay deteriorating.
  • SMT surface mounting technology
  • connection technology with press-in pins are increasingly desired for the assembly of printed circuit boards in addition to the conventional contacting via solder pins
  • relays should, if possible, also be designed to withstand the mechanical or thermal loads that occur with these techniques withstand without the precisely set characteristic values of the relay deteriorating.
  • the base body unit forms the lower part of the housing with respect to the connection level and the armature is located in the upper area, the contact connections have to be guided downwards next to the coil. This not only makes the connections very long, they also require additional space, which together with the necessary insulating partition walls increases the width of the relay.
  • the aim of the present invention is to construct a relay structure of the type mentioned at the outset in such a way that the insulation strength between the magnetic circuit and the winding is improved in the simplest possible manner and, at the same time, the mechanical stability of the relay is increased with the smallest possible volume;
  • Different connection technologies in particular also SMT connections and press-in handles, should be able to be used without changing the other construction.
  • this goal is achieved in the aforementioned relay structure in that a base body is formed by increasing the coil on all sides with insulating material, which together with the base forms a cuboid housing, the coil together with the core in the upper region of the base body is embedded and insulated downwards by a partition and the base body has downwardly formed side walls which enclose the base in the shape of a box and form a closed switching space with it.
  • This stable structure has a particularly advantageous effect if the base body has a shoulder on both sides of the armature, under which the contact terminal pins are arranged in a row and which is suitable as a support area for these terminal pins if required. It can also be advantageous to additionally include the two yokes in the extrusion coating. If the system is polarized, an associated permanent magnet can either be subsequently inserted into a corresponding recess or embedded in the manufacture of the base body.
  • solder pins are bent downward from a printed circuit board injected into the base.
  • the stable structure according to the invention is particularly effective, however, when connecting pins are used which extend vertically upwards from the base up to the respective supporting area of the base body, in order to avoid overdetermination during manufacture, is advantageously provided hen that the connection pins are each arranged in grooves of the base body in the support area and are fixed there by means of curable sealing compound. It is thus possible that after the armature has been installed on the base and the precise setting of the contact distances has been carried out, the base body with the magnet system can be pushed onto the base until the armature lies exactly against the magnet system or has reached the specified air gaps to the yokes.
  • the base body can then be sealingly connected to the base by pouring in adhesive or potting compound the connecting pins are cast and fixed in the grooves mentioned in a preceding or simultaneous operation.
  • This switch room also has a very small air volume compared to relays of similar design, since the coil room is not included. This is particularly advantageous in the case of strong heat, such as when soldering the relay, in particular when reflow soldering SMT connections.
  • FIG. 1 shows a relay designed according to the invention when the base body is mounted with a magnet system (partially cut open) on the base equipped with the armature,
  • FIG. 2 shows a longitudinal section through a base body
  • Figure 3 is a perspective body shown in
  • FIG. 4 shows a basic body in longitudinal section corresponding to FIG. 2, but with an additionally embedded permanent magnet
  • FIG. 5 shows a longitudinal section corresponding to FIG. 2 of a basic body with cutouts for the yokes.
  • the polarized relay shown in FIGS. 1 to 3 essentially has two assemblies, namely a basic body 1, which contains a magnet system, and a base 2 with an armature and a contact arrangement.
  • the base body 1 has essentially a cuboid shape on the outside, which is formed by extrusion coating of the magnet system.
  • This magnet system contains a coil consisting of a coil body 3 and a winding 4.
  • a rod-shaped core 5 is arranged in an axial through opening of the coil body. The ends of the core 5 projecting from the coil body 3 are coupled to two yokes 6 and 7, which in the example of FIGS.
  • the bobbin has recesses made of the material of the Base body 1 are filled, it is production-related interruptions of this coil body design; however, a conventional coil former with a continuous insulating tube could also be used as the winding carrier. In any case, however, the plastic material of the base body 1 encloses the coil winding on all sides, so that good insulation from the metal parts of the magnetic circuit and - by a partition 18 on the underside of the coil - above all from the contact elements is guaranteed.
  • the magnet system also contains a permanent magnet 8 shown in FIG.
  • the permanent magnet can be attached with crush ribs 9 of the base body.
  • other fastening options are also conceivable.
  • the base body 1 also has molded on the underside, all-round side walls 11 with which the
  • Base body 1 can be plugged onto the base 2.
  • the side walls 11 encompass the base 2 in a box-shaped manner and form a closed switching space 10 between the magnet system and the base.
  • the base body 1 there are two longitudinal webs 12 parallel to the coil axis or to the long sides of the base body intended. Together with the parallel side walls 11, these each form a longitudinal groove 13 with a support surface 14 on its upper side, which - if necessary - serve to support and stabilize the contact connections to be described.
  • Two pairs of fixed contact connections 21 are anchored in the base 2 and are connected to fixed contacts, likewise not visible, via a printed circuit board which is not visible and is embedded in the base.
  • two mutually opposite center contact connections 22 are anchored, which are connected to center contact springs 24 via bearing strips 23.
  • These center contact springs 24 are connected in a known manner to an armature 25, which is held in the bearing via the bearing belts 23 in a likewise known manner.
  • connections 21 and 22 each have support sections 2la and 22a which project above the upper side of the base and which come to rest in the groove 13 between the respective side wall 11 and the respective longitudinal web 12 when the base body 1 is placed on the base 2. You can, for example, either be supported directly on the support surface 14 inside the groove 13. To compensate for tolerances, however, it is more advantageous to fill these grooves 13 each time after assembly with casting compound, which reliably stabilizes and supports the connecting elements after curing.
  • the structure of the relay apart from the new basic body shape, is largely similar in function to that of the relay according to WO 94/22156 mentioned at the outset, so that there is no need to go into this here.
  • FIGS. 4 and 5 modifications of the base body can be seen in the same representation as in FIG. 4 shows an embodiment in which the permanent magnet 8 is already embedded with the yokes 6 and 7 during the manufacture of the base body 1.
  • FIG. 5 shows another embodiment, in which the embedding of the base body l only comprises the coil with the coil body 3 and winding 4 and the core 5, while special pockets 16 and 17 are recessed for the yokes, into which they are subsequently added can be inserted.
  • the permanent magnet 8, as already shown with reference to FIG. 2 is subsequently inserted and fixed by means of pinch ribs 9.
  • connections 21 and 22 can be varied depending on the type of connection technology used. 1 shows press-in handles which are pressed into contact holes of a printed circuit board with high press-in pressure. the and result in a solderless connection. In this case, the support of the support sections 21a and 22a in the base body is particularly important, since in this way the press-in forces can be transmitted to the connections via the base body.
  • the relay structure can also be used for other connection technologies.
  • press-in pins shown normal soldering pins or SMT connecting lugs bent at the side can also be provided.
  • the support in the basic body is not necessary to the same extent. It can still be provided to stabilize the overall structure.
  • the coil connecting pins 15 also anchored in the base body are always designed in accordance with the contact connecting elements.
  • the invention is not limited to polarized relays according to the exemplary embodiment.
  • Another polarized magnet system or a known neutral system could certainly be accommodated in the base body 1 and actuate the contact arrangement.
