Definitions
- the invention relates to a relay
- An electromagnetic system connected to the base body with a coil, a core and an armature and
- a contact unit for such a relay is known from DE-AS 20 39 939.
- contact springs or mating contact carriers are anchored in a common plane in an insulating body, with a lateral overlap of the contacting ends being achieved by angled portions. This requires a series of precise bending processes in the production of the contact elements, and the assembly in the insulating material body, which is preferably carried out there by embedding, also requires complex guidance and alignment.
- this goal is achieved in that all contact springs are designed as flat leaf springs without permanent bending and in that the fixed contact spring receives a prestress by resilient deflection from its clamping plane against a stop of the base body.
- the contact arrangement which in the simplest case is designed as a break contact or a make contact, only has contact springs punched out of a flat sheet metal and in no way pre-bent, which overlap due to the L-shaped design of at least one spring end.
- the movable contact spring rests in the usual way on the slide, by means of which it can also be more or less deflected from its plane in the idle state, depending on the type of contact.
- the contact springs are very inexpensive and easy to manufacture, since the respective spring characteristic is not achieved by permanent bends on the contact springs, but by the geometry of the base body with the stop, at least for the fixed contact spring.
- a particularly simple design of the relay is obtained when serving flanges a Spulenkorper with two coils ⁇ as a base body, wherein the contact springs are anchored approximately parallel to the coil axis in a first coil flange and the bias generating stop is provided on the second coil flange. Production is particularly cost-effective, in particular, when the fixed and the movable contact spring are of identical design, and they are used in mirror image with respect to one another on the common plane m of the basic body.
- the magnet system has a T-shaped core, the longitudinal leg of which extends axially through the coil body, a U-shaped armature being arranged on the side of the coil body facing away from the contact springs and with its crosspiece in the region of the first coil flange the free end of the core long leg is mounted and the anchor actuates the slide with the free ends of its long arms.
- a particularly simple design of the relay with few parts also results from the fact that the movable contact spring also exerts a restoring force on the armature via the slide.
- the armature is pressed into its bearing at the core end via a pivot point in the central region of its long legs by the restoring force of the contact spring.
- This fulcrum can be created without additional parts in that the anchor has molded shoulders on both sides, which abut an inner edge of a housing cap.
- an integrally formed back part spring arm which is decoupled from the contact spring itself, acts on the slide and prestresses the armature m via its rest position. Due to the shaping of the reset Federar s at a fixed ⁇ stationary contact spring, which is already supported on the base body, the movable contact spring can be designed in their dimensions and spring characteristics alone to produce the respective contact pressure. Thus, in a simple Wei ⁇ se also a make or a changeover realized. In addition to the additional opening spring, no further individual parts are required; the movable contact spring and the normally open contact spring can be used as with the normally open relay without any design changes.
- the return spring arm is preferably molded onto the fixed break contact spring, as a result of which there is no overlap with the movable contact spring and the structurally simplest solution results.
- FIG. 1 shows a normally open relay according to the invention in an exploded view
- FIGS. 2 and 3 show a fully assembled relay according to FIG. 1 - without a cap - in two perspective views
- FIG. 4 shows the fully assembled relay from FIG. 1 in a section through the coil axis
- FIG 5 shows a changeover relay designed according to the invention in an exploded view
- FIG. 6 shows the relay from FIG. 5 in a semi-assembled state, but without a movable contact spring and without a normally open contact spring
- FIG. 7 shows a fully assembled relay - without a cap - in a perspective view.
- the relay shown in the drawing consists of a coil former 1, a T-shaped or approximately M-shaped core 2, a U-shaped armature 3, a card-shaped slide 4, a fixed contact spring 5, a movable contact spring 6, a cap 7 and two coil connecting pins 8 anchored in the coil body.
- the coil former 1 has an axial through opening 11 and a first flange 12 and a second flange 13, between which a winding 14 is applied.
- the end face a lug 14 for Ankerla ⁇ is formed delay on reel flange 12 integrally, which merges into a base plate 15 °.
- Limiting pins 16 for the armature are also integrally formed on the extension 14, and plug slots 17 are also formed in this extension, through which connection elements 51 and 61 of the contact springs 5 and 6 can be guided vertically outwards through the base plate 15.
- a stop lug 18 for the fixed contact spring 5 is also formed on the second coil flange 13.
- the T-shaped core 2 has a longitudinal leg 21 which is inserted into the through opening 11 of the coil body, and two transverse legs 22, at the ends of which side arms 23 are attached parallel to the longitudinal leg 21.
- the U-shaped armature 3 consists of two Railnar en 31 and a transverse web 32, the latter being mounted on the free end portion 24 of the core 2 and then lying in a recess between the first coil flange 12 and the base plate 15.
- the free ends of the longitudinal arms 31 are widened into hook-shaped pole ends 34 which grip around the second coil flange 13 and form two parallel working air gaps with the transverse legs 22 and their side arms 23 of the core.
- the fixed contact spring 5 and the movable contact spring 6 are anchored with their connecting elements 51 and 61, which are integrally formed or fastened in a known manner, in the plug-in slots 17 of the base attachment 14.
- the two contact springs 5 and 6 are of identical design and are provided with contacts 52 and 62, respectively. The mutual overlap for making contact results from an L-shaped bend at their movable, contact-making ends.
- the contact springs 5 and 6 are only cut from a flat sheet metal plate without bending and inserted into the coil body. The mutual offset of their contacting ends results only from the geometry of the coil body or the slider 4.
- This slider lies between the coil flange 13 and the transverse legs 22 of the core. It has a recess 41 through which the longitudinal core leg 21 is inserted.
- the L-shaped bent end section 63 of the movable contact spring 6 bears against the stop lug 18 of the coil former 1 and thus receives its rest bias.
- the L-shaped bent end section 53 of the fixed contact spring 5 bears against the slide 4.
- the end section 63 is moved in the direction of the end section 53 of the fixed contact spring 5 and lifts the latter from its stop on the nose 18. This creates the contact force.
- the cap 7 is put over the relay. It forms a closed housing with the base plate 15. As can be seen from FIG. 4, the cap 7 has a ventilation hole 71 in the area of its upper side, which opens into an inwardly projecting extension 72. The latter approach forms an additional guide for the slide 4. As can also be seen from FIG. 4, the armature 3 is biased into its rest position by the restoring force of the working contact spring 6 via the slide 4. Lateral shoulders 35 of the armature abut ribs 72 of the cap, thereby forming a pivot point 73 for the armature.
- the changer relay shown in Figures 5 to 7 consists of a coil body 1, a T-shaped or approximately T-shaped core 2, a U-shaped armature, a hardlyför ige slide 4, a fixed NO contact spring 5, a movable contact spring 6, a fixed break contact spring 9, a cap 7 and two coil connection pins 8 anchored in the coil body.
- the individual parts have the same or similar design as in the previous example of the closer relay, they have the same reference numerals and are no longer described separately.
- the break contact spring 9 is in a slot 19 of the
- the contact springs 5 and 6 are only cut from a flat sheet metal plate without bending and inserted into the coil body.
- the fixed break contact spring 9 is also cut from a flat sheet metal plate and inserted into the coil body, namely the slot 19. It has a contact 92 which faces the movable contact 62.
- a rear part spring arm 94 is formed on the opener contact spring 9 in the same plane, which is decoupled from the actual opener contact spring, projects beyond its free end and acts as a return spring.
- the L-shaped bent end section 63 of the movable contact spring 6 bears against an actuating nose 43 of the slide 4.
- the slide is also guided via a guide lug 42 in an opening 64 in the contact spring 6.
- the slide has an additional stop lug 44 against which the rear spring arm 94 rests and biases the armature into its rest position via the slide.
