Definitions
- the invention relates to an electromagnetic relay
- a housing base body which surrounds a magnet system chamber on one side of the partition wall and at least one contact chamber on the other side of the partition wall with all-round side walls and a partition wall perpendicular to a bottom side,
- a magnet system carried by the base body in the magnet system chamber with a coil, the axis of which lies parallel to the bottom side, an armature which is arranged on the end face of the coil facing away from the contact chamber,
- the base body is in the form of a housing cap, in which both the magnet system space and the contact space on the top are closed, while both of them are initially open downwards to the bottom side or connection side of the relay and are then closed by a base plate the. Both the contact elements and the magnet system are thus fastened in the housing from the bottom side.
- an additional separating sleeve is provided there, for example, which is plugged onto the coil following the partition and with it in the magnet system space be- is increased. The fastening of the magnet system from the underside in the housing cap was also allowed to create additional problems.
- a relay with a similar structure is also known.
- the coil is inserted in the axial direction into a cassette-like housing, on the closed side of which a spring bracket is formed.
- a cap placed from above encloses the armature attached to the open housing side and the contact elements standing freely on the spring bracket on the opposite side, as well as a slide located above the housing.
- the cassette-like housing and the cap form a double wall over most of the housing sides, without this resulting in an improvement in the insulating distances in the relay.
- the double walls essentially increase the volume.
- the aim of the invention is to create a relay of the type mentioned at the beginning, the housing construction of which, with the smallest possible volume, ensures the greatest possible insulating distances between the coil and contacts and which is simple to manufacture with as few simple parts as possible.
- the magnet system chamber in the base body is open at the top and at least partially closed at the bottom by means of a bottom wall which extends in one piece from the partition between the coil and slide over a substantial part of the coil length.
- the magnet system chamber on the one hand and the contact chamber or the contact chambers on the other hand are molded in opposite directions into the basic body. This means that the contact elements can be inserted into the respective downwardly open contact chamber from below, while the magnetic system in the opposite direction from the top can be inserted into the magnetic system chamber, which is open at the top.
- the reason why the magnet system chamber on the underside cannot be completely closed is simply because the free armature end pointing downward must be coupled to the slide. However, this takes place in the area opposite to the contact chamber, so that the bottom wall formed on the base body in any case ensures a sufficiently large insulating gap between contact elements and coil for all applications.
- this bottom wall is also large enough to support the magnet system used from above.
- the exact length of the bottom wall in the axial direction of the coil can be adapted to the respective requirements with regard to the insulating distances. In any case, however, it will extend over at least half the coil length and thereby sufficiently close off the magnet system space.
- the contact elements can be fastened in a manner known per se from the bottom in slots in the side walls. It is also possible to accommodate several contact sets in one contact chamber. In a preferred embodiment, however, it is provided that two or more contact chambers which are open at the bottom and are separated from one another by intermediate walls are formed in the base body. The individual movable contact springs in the individual contact chambers can all be actuated together by the slide movable on the underside.
- the slider can be guided in its longitudinal direction through the bottom wall, which for example projects into a longitudinal recess of the slider with an integrally formed guide rail.
- the switching stroke of the slide and thus the armature stroke can be limited by a stop lug formed on the bottom wall.
- This stop nose can for example by a recess of the slide down protrude and be accessible from the bottom for thermoplastic deformation. In this way it is possible to reduce the rest position of the slide and thus the armature stroke by thermoplastic deformation of the stop lug and thus to adjust it.
- Figures 1 to 3 a relay designed according to the invention in two sectional views and in a bottom view.
- the relay shown in Figures 1 to 3 has one
- Basic body 1 which has a partition wall 2 perpendicular to the bottom side and with all-round side walls 3 also running perpendicular to the bottom side, on one side of the partition wall 2 an upwardly open magnet system chamber 4 and on the other side of the partition wall 2 downwards forms open contact chambers 5 and 6.
- the two contact chambers 5 and 6 are separated from one another by an intermediate wall 7. Due to the closed top wall 8 of the contact chambers and the bottom wall 9 of the magnet system chamber, very long insulating distances between the contact system and the magnet system result from the design of the basic body.
- An electromagnet system consisting of a coil 10, a core 11, a yoke 12 and an armature 13, is inserted into the magnet system chamber 4 from the open upper side.
- this magnet system is inserted without an armature and brought in the axial direction to a predetermined distance from the partition 2 and thus from the contact chambers 5 and 6. In this position it is then fixed in the usual way, for example by gluing or by thermoplastic deformation of the base body and / or the coil body.
- the armature 13 is then also inserted from above together with an armature spring 14.
- the anchor spring 14 is anchored with a fastening leg 14a in vertical slots 15 of the base body.
- the contact sets in the contact chambers 5 and 6 each consist of a rigid center contact element 16 or 19 and two movable contact springs 17 and 18 or 20 and 21.
- the rigid center contact elements 16 and 19 and the contact springs 17, 18, 20 and 21 are anchored in slots 22 of the base body either directly or with correspondingly cut free fastening sections.
- Connection lugs 16a, 17a, 18a and 19a, 20a and 21a are led out to the bottom side.
- the connecting lugs of the two contact sets are offset from one another in such a way that the largest possible insulating distances result in the smallest possible space requirement.
- the coil connections 23 are located at the opposite end of the basic body, so that they too have very large insulating distances from the contact elements. All contact parts are otherwise simple sheet metal parts that are either plane or simply bent out of one plane. They carry rivet contacts so that welding of beams and springs is not necessary.
- a flat slide 24 is used to actuate the contacts and is inserted with actuation slots 25 from below over the free ends of the contact springs 17, 18, 20 and 21 and over an anchor pin 26. It is mounted between the base wall 9 of the base body and a base plate 27 which is additionally attached from below and can be moved parallel to the base side. In the area below the magnet system chamber, the slide has a recess 28 into which a rib 29 of the bottom wall 9, which serves as a guide, projects.
- the slide 24 coupled to the armature is pretensioned by the armature spring 14 into a rest position, to the right in FIG. 1.
- a stop lug 30 protruding through the recess 28 of the slide, against which the slide strikes with its shoulder 28a serves to limit the stroke.
- this stop lug 30 By thermoplastic deformation of this stop lug 30 in the direction of arrow B, this lug can also be deformed to a small extent in the direction parallel to the floor plane, thereby increasing the stroke of the slide and the anchor can be reduced somewhat. In this way, the response values of the relay can be adjusted within particularly narrow limits.
- the housing is finally closed by the base plate 27 already mentioned and by a cover 31 placed on the open upper side of the magnet system chamber 4.
- a cover 31 placed on the open upper side of the magnet system chamber 4.
- an additional insulating wall 32 is molded onto this cover 31, which isolates the insulation between the magnet system chamber and Contact chambers further improved.
- both the base plate 27 and the cover 31 can optionally be additionally cast.
- contact chambers 5 and 6 instead of the contact chambers 5 and 6 shown, only a single contact chamber or also a plurality of contact chambers could be provided; in which one or more contact sets can be arranged side by side or one behind the other in the direction of actuation.
