Definitions
- the invention relates to an electromagnetic relay with the following features:
- an L-shaped armature which is supported at one end at a first end of the core and at its other end forms a working air gap with respect to the second end of the core, such that the core and armature form an approximately rectangle when the working air gap is closed, whereby a magnet system is formed by coil, core and armature,
- a base body made of insulating material, which is connected to the magnet system on the side of the coil opposite the armature and in which at least one fixed contact element and at least one contact spring cooperating with it are contained as a movable contact element, the contact elements being connected to connection elements , and - a slide transmitting the armature movement to the at least one contact spring.
- this aim is achieved in that the base body is arranged as an essentially flat base parallel to the coil axis below the coil, and that the at least one contact spring between the coil and the base extends parallel to the coil axis, while the connecting elements run perpendicular to it through the Base are guided outwards, that the armature with its cross leg is mounted on the free end of the longitudinal leg on the core, that the longitudinal leg of the armature extends above the coil, that the cross leg of the core has a pole face upward to form the working air gap, and that the magnet system in the region of the core transverse leg has lateral attachment extensions which engage with the base of the base.
- the end sections of the longitudinal arm leg and core transverse leg forming the working air gap are widened in a T-shape, as a result of which the magnetic resistance in the area of the working air gap is reduced.
- the fastening extensions on the core are formed on both sides starting from the widened end section downwards.
- the fastening extensions are designed in the form of hooks, for example as snap lugs, so that they can be locked with recesses formed on the projections of the base, as a result of which the magnet system and base are connected to one another in a type of press fit. On the one hand, this contributes to a stiffening of the overall system, on the other hand, no additional effort is required to attach the magnet system to the base.
- fastening chambers for flange extensions of the coil body are formed in the base, which plug-in channels for
- a support pin is formed on the base, which is provided with a locking lug.
- This locking lug is hooked with a cross bar, which is formed between the bottle extensions on the coil body, so that an additional fastening of the base and magnet system is realized.
- the advantage of the features mentioned is that the distance between the contacts and the working air gap is set with low tolerance, in that the core or the coil former is connected directly to the base as a contact carrier. In this way, a summation of tolerances is avoided. Due to the extremely low tolerance arrangement of the magnet system and base to each other, not only precise guidance of the Slider reached, but also allows a precise definition of the overstroke for the contact elements.
- the contact springs are advantageously actuated via an essentially U-shaped slide which is coupled to the armature and which engages around the magnet system with its side arms and whose central section acts on the contact springs. Furthermore, actuating elements pointing downward are formed on the lower edge of the central section of the slide.
- the number of actuating elements corresponds to the number of contact sets contained in the relay, consisting of a contact spring and at least one counter-contact element.
- the actuating elements can be easily molded onto the actuating element, which is preferably manufactured as a molded plastic part, without any appreciable additional effort.
- the actuating elements protrude on the base into contact chambers in which the contact sets are arranged.
- the individual contact sets are isolated from one another by the side walls of the contact chambers.
- the side walls of the contact chambers can be made sufficiently high for the insulation of the contact sets with a compact relay design. Effective precautions for isolating the individual contact sets are thus easily integrated into the relay.
- the choice of the height of the actuating elements gives another possibility of defining the overstroke.
- Recesses provided in the side walls of the contact chambers for the central section of the slide further improve its guidance.
- a pair of upward-facing guide rails is attached to both sides of the base, which engages around an outwardly projecting guide pin formed on the outer edge of a slide side arm and secures it against lateral displacement when the slide moves up and down.
- a U-shaped armature spring which with a first arm is fastened to the longitudinal arm leg, is arranged in the middle section approximately parallel to the armature transverse leg and is fastened with the second arm in a recess between the core and the coil former parallel to the longitudinal core leg.
- the recess between the core and the bobbin is best formed in the form of a stepped space on the bobbin.
- the second arm of the armature spring which is inserted into the recess between the coil body and the core, is preferably equipped with a latching lug which is hooked into the core directly above.
- the armature spring including the armature firmly connected to it, on the one hand, and the coil body with the core arranged therein, on the other hand, is not readily possible.
- the locking lug can be produced, for example, by punching it out of the spring plate and then bending it over, so that it conforms to the embossing in the core in a force-fitting and form-fitting manner.
- the fixation of the armature spring is improved by the support pin integrated in the base, which serves to position the magnet system in the area of the coil connection side.
- the aforementioned advantageous design features of the relay according to the invention result in a very simple assembly process, which can also be carried out without a large amount of tools or specialized workers.
- the base is preferably equipped with the contact and connection elements at the same time for mounting the magnet system.
- the formation of fastening and contact chambers on the base, which in this context serve as pockets for the components to be accommodated, proves to be a further advantage.
- the anchor spring is preferably attached to the anchor in advance.
- the arm of the armature spring containing the locking lug is inserted into the recess between the coil body and Inserted core until the locking lug hooks into the embossment provided in the core.
- the slide is then expediently suspended from below on the armature spring lobe, which completes the assembly of the magnet system, including the coupling of the slide.
- only the magnet system and base are connected to one another by means of the fastening elements according to the invention.
- FIG. 1 shows a relay according to the invention in a three-pole version in a perspective view
- FIG. 2 shows a magnetic system with inserted winding connection elements in a perspective view
- FIG. 3 shows a base equipped with contact sets in a perspective view
- FIG. 4 shows a magnet system without winding in longitudinal section and
- FIG. 5 shows a relay according to the invention with fastening projections molded onto the coil flange.
- the relay according to the invention consists in its main components of an assembled magnet system 1, a U-shaped slide 8 suspended on the armature, a base 6, contact sets and winding 74 and contact connection elements 73 formed by contact springs 71 and mating contact elements 72
- FIG. 5 shows the alternative design of the fastening extensions 34, which in this case are formed on the outer edges of a coil flange 21 in the vicinity of the working air gap.
- the contact chambers 63 which are formed in the base 6 and which accommodate the contact sets consisting of contact springs 71 and counter-contact elements 72 can be seen from FIG.
- the individual contact sets of the three-pole relay are insulated from one another by the raised side walls of the contact chambers 63.
- the recesses 64 embedded in the side walls of the contact chambers 63 likewise serve to improve the guidance of the slide 8 in the region of the central section 82.
- molded actuating elements 83 are provided which protrude into the individual contact chambers 63 (FIG 2).
- FIG. 2 also shows the fastening of the winding connection elements 74, which are inserted at their upper end into plug-in channels 23 contained in the flange extension 22.
- the winding connection elements 74 are bent in the central region. With her free de the winding connection elements 74 protrude vertically through the base plane of the base 6.
- FIG. 4 shows those components of the magnet system 1 which are used to fasten the armature spring 5.
- the flat cuboid free space 24 can clearly be seen, which receives an arm of the armature spring 5.
- the arm of the armature spring 5 inserted into the free space 24 contains a locking lug 51 which is hooked into an embossment 35 on the underside of the core 3.
- the arm of the armature spring 5 lying above the armature longitudinal leg 41 is firmly connected to the armature 4 via rivet warts 44 attached to the armature longitudinal leg 41, so that the armature spring 5 is preloaded and at the same time is supported.
- a protective cap made of insulating material which is not explicitly shown in the description of the exemplary embodiments, is slipped from above over the arrangement consisting of magnet system 1 and base 6, so that the relay is externally encapsulated .
