Definitions
- DE-AS 20 39 939 is a contact unit for such a Relay known.
- the aim of the present invention is to provide a relay of the input to create the kind mentioned that with contact springs in is equipped as simple as possible, these contact springs easy to manufacture and assemble should be so that the relay overall is particularly inexpensive can be produced.
- this goal is achieved in that all Contact springs as flat leaf springs without permanent bending are formed and that the fixed contact spring on a Pre-tensioning of the base body by elastic deflection from its clamping plane.
- the contact arrangement has in the simplest case as opener or as Closer is formed, only from a flat sheet stamped and in no way pre-bent contact springs, the due to the L-shaped design of at least one spring end overlap each other.
- a preload of the fixed Contact spring at rest and a contact distance as far as it is is a work contact is by a stop of the base body on which the contact spring in question only due to the insertion in the base body is present and experiences a corresponding deflection.
- the movable contact spring in turn is in the usual way the slider, by means of which, depending on Art of contact, also more or less out of her Plane can be deflected.
- the contact springs very inexpensive and easy to manufacture because the respective spring characteristic not due to permanent bends the contact springs, but by the geometry of the base body with the stop, at least for the fixed contact spring, is achieved. With several contact springs of course, several different attempts to achieve this provided according to different preloads his.
- a particularly simple design of the relay results when a coil body with two coil flanges is used as the base body serves, the contact springs approximately parallel are anchored to the coil axis in a first coil flange and the biasing stop on the second Coil flange is provided. Is particularly inexpensive the production especially when the fixed and the movable contact spring are identical, wherein they mirror each other in the common plane in the basic body can be used.
- the magnet system has a T-shaped core, the Longitudinal leg extends axially through the coil former, a U-shaped armature on the side facing away from the contact springs Arranged side of the bobbin and with his Cross bar in the area of the first coil flange on the free End of the core longitudinal leg is mounted and the anchor actuated the slide with the free ends of its longitudinal arms.
- a particularly simple design of the relay with few Sharing also results from the fact that the movable contact spring a restoring force on the Anchor exercises.
- this is furthermore provided that the anchor has a fulcrum in the central area its longitudinal leg by the restoring force of the Contact spring is pressed into its storage at the core end.
- This pivot point can be created without additional parts be that the anchor is molded on both sides Has shoulders attached to an inner edge of a case cap invest.
- the movable contact spring Due to the shape of the return spring arm on a fixed one Contact spring, which is supported on the base body anyway is, the movable contact spring in its dimensions and spring properties only to generate the respective Contact pressure are formed. This is simple an NC or changeover contact can also be implemented. Besides the additional opening spring, there are no others Individual parts required; the movable contact spring and the Normally open contact spring can like without design change be used with the normally open relay.
- the Return spring arm on the fixed break contact spring integrally formed, so that no overlap with the movable Contact spring occur and become the structurally simplest Solution results.
- the relay shown in the drawing consists of a Coil body 1, a T-shaped or approximately M-shaped Core 2, a U-shaped anchor 3, a card-shaped slide 4, a fixed contact spring 5, a movable Contact spring 6, a cap 7 and two anchored in the coil body Coil connector pins 8.
- 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. Face is an extension 14 for armature mounting on the coil flange 12 in one piece molded on, which merges into a base plate 15. On the approach 14 are limiting pins 16 for the anchor integrally formed, there are also slots in this approach 17 molded through the connecting elements 51 and 61 of the contact springs 5 and 6 through the base plate 15 vertically can be led outside. On the second coil flange 13 is also a stop lug 18 for the fixed contact spring 5 molded.
- the T-shaped core 2 has a longitudinal leg 21 which in the through opening 11 of the coil body is inserted, and two cross legs 22, at the ends of each side arms 23 are attached parallel to the longitudinal leg 21.
- the U-shaped Anchor 3 consists of two longitudinal arms 31 and one Crossbar 32, the latter on the free end portion 24th of the core 2 is stored and then in a recess between the first coil flange 12 and the base plate 15 lies. Through the two locking pins 16 of the base approach 14 which engage in corresponding recesses 33 in the armature, he is secured against lateral movements without that his switching movement would be hindered.
- the free ends of the Longitudinal arms 31 are widened into hook-shaped pole ends 34, which encompass the second coil flange 13 and with the transverse legs 22 and their side arms 23 of the core two parallel Form working air gaps.
- the fixed contact spring 5 and the movable contact spring 6 are with their connecting elements 51 and 61, which are integrally formed or fastened in a known manner, anchored in the plug-in slots 17 of the base attachment 14. in the The present example is the two contact springs 5 and 6 executed identically and provided with contacts 52 and 62 respectively.
- the mutual overlap for contacting results through an L-shaped bend on their movable, contact-making End up.
- the contact springs 5 and 6 are only made of one without bending Cut flat sheet metal and into the coil body plugged in.
- the mutual offset of their contact Ends only result 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. He owns a recess 41 through which the longitudinal core leg 21 is put through.
- After assembling the parts lies the L-shaped bent end portion 63 of the movable contact spring 6 on the stop lug 18 of the bobbin 1 and receives its resting tension.
- the cap 7 After assembling the individual parts described, the cap 7 put over the relay. It forms with the base plate 15 a closed housing. As can be seen from Figure 4 the cap 7 has a ventilation hole in the area of its upper side 71 on that in an inward protruding approach 72 flows. The latter approach forms an additional guide for the slide 4. As can also be seen from FIG. 4, the armature 3 over the slide 4 by the restoring force the working contact spring 6 biased to its rest position. Lateral shoulders 35 of the anchor abut ribs 72 the cap, thereby forming a pivot point 73 for the anchor becomes. About this fulcrum 73 is due to the leverage the stored end or the crossbar 32 of the anchor in the storage and pressed against the end portion 24 of the core. Thereby reproducible flow transition ratios result in the anchor position and a correspondingly low response excitation.
- the changeover relay shown in Figures 5 to 7 consists of a bobbin 1, a T-shaped or approximately T-shaped Core 2, a U-shaped anchor, a card-shaped Slider 4, a fixed NO contact spring 5, one movable contact spring 6, a fixed break contact spring 9, a cap 7 and two anchored in the coil body Coil connection pins 8.
- the break contact spring 9 is in a slot 19 of the Base plate 15 attached. While the two contact springs 5 and 6 with their sheet metal levels in a common level in the Plug slots 17 are attached, the sheet metal level of the contact spring 9 in the slot 19 compared to the former slightly offset, but arranged parallel to it. All contact springs are with side flaps 55 or 65 and 95 provided with which they are on the top of the respective plug slots 17 and 19 abut while on the Underside each of bending tabs 56, 66 and 96 as a fuse can be deformed.
- the contact springs 5 and 6 are also in this case without bending just cut from a flat sheet metal plate and inserted into the bobbin.
- the fixed break contact spring 9 is also cut from a flat sheet metal plate and in the bobbin, namely the slot 19, inserted. It has a contact 92 which is movable Contact 62 faces. It is also on the break contact spring 9 a return spring arm in the same plane 94 molded on by the actual break contact spring is decoupled, projects beyond its free end and acts as a return spring.
- the L-shape is bent End section 53 of the fixed NO contact spring 5 on the stop lug 18 of the bobbin 1 and thus receives his resting bias.
- the L-shaped curve lies End portion 63 of the movable contact spring 6 on one Actuating nose 43 of the slide 4.
- the slider will also via a guide lug 42 in an opening 64 of the Contact spring 6 out.
- the slide has one additional stop lug 44 on which the return spring arm 94 rests and the anchor in its rest position via the slide preloaded.
