Definitions
- the invention relates to a relay with a base body, the defines a basic level, one arranged on the basic body Magnet system with coil, core and armature, with at least two pairs of contact springs, each pair of contact springs one passive and an active contact spring and each includes Contact spring standing perpendicular to the base plane in the base body is attached and on her removed from the base body End carries a contact piece, also with an actuating slide, which is movable parallel to the base plane and on each active contact spring in the vicinity of the Contact piece attacks.
- Such a relay is for example from US 52 89 144 A known.
- the magnet system is parallel to the coil axis arranged to the base plane on the base body, wherein the active and passive contacts forming changeover contacts Contact springs in front of one end of the magnet system in the Base bodies are anchored while the anchor is on the opposite Front of the magnet system lies and over one the active slider extending above the coil Contact springs actuated.
- the aim of the present invention is to provide a relay of the input mentioned type so that the arrangement of the Contacts and their operation provide the greatest possible security ensure, but at the same time also high dimensional accuracy the contact distances and the actuation is reached.
- this goal is achieved in that all Contact springs in the mounting channels of the base body Insert perpendicular to the base plane that the Slide at least every active contact spring all around in the form of a frame, being inside each Frame a window for the implementation of the contact spring in the area between their attachment and their contact piece is recessed and wherein the cross section of the contact spring end portion including the contact piece is larger than the cross-section of the window.
- the one enclosing the single active contact spring Frame preferably has partitions, which surround the end portion carrying the contact piece all around.
- a partition of the frame preferably has one Cutout in which the contact piece of the respective active contact spring guided in its direction of actuation is, the contour of the partition wall each a locking portion has a relative movement of the active contact spring opposite the slide in the direction of the associated passive contact spring locks.
- the invention are actuating lugs on the slide molded for each active contact spring, such that each active contact spring between a locking section the partition and an operating lug with little Game is led.
- the relay shown in Figures 1 to 6 has one Base body 1 made of insulating material, which is designed essentially flat is defined and a bottom side 10 and with a Cap 2 forms a closed housing.
- the basic body 1 has a flat, trough-shaped recess 11 for receiving a magnet system, while the rest of the system is drawn up Side walls 12, a longitudinal partition 13 and transverse walls 14 forms two rows of contact carrier chambers 15.
- This Contact carrier chambers 15 are slit-shaped towards the bottom Plug channels 16 narrowed (see Figure 4), each from above, perpendicular to the base plane 10, insertable fixed contact carrier 21 or contact spring support 22.
- the fixed contact carrier 21 form passive (or fixed) contact springs 23 with fixed contact pieces attached 24, while on the contact spring supports 22 each active (or movable) contact springs 25 with at their free Ends attached movable contact pieces 26 attached are.
- the magnet system used to operate the relay a U-shaped core yoke 31 with a core leg 32 and one Yoke leg 33.
- a coil former 34 carries an excitation coil 35 and takes in an axial through hole Core leg 32 on. Because of the limited spool width has a smaller width than the yoke leg 33, is an additional flow guide part 36 together with the Core leg 32 inserted into the coil interior. To this The iron cross-section inside the coil becomes the same enlarged like the pole surface 32a or 36a with which an armature 37 cooperates.
- This anchor is with the help of an anchor spring 38 mounted and forms at the free end of the yoke leg 33 with the pole faces 32a, 36a in the usual way a working air gap. Generate two return legs 39 of the armature spring 38 the rest position of the contacts when not excited of the magnet system.
- the movement of the armature 37 is controlled by an armature extension 37a on a slide 40 and above this on the active contact springs 25 transferred. Since the contact springs on the Anchor opposite side of the magnet system are, the slide has an extending above the coil Connection section 41, to which a downward stepped towards the ground level Actuating section 42 connects.
- This operating section forms with a central longitudinal wall 43 and side walls 44 and cross walls 45 and 46 each have frames for each single contact spring that these contact springs, with the exception the respective first passive contact springs 24R and each last passive contact springs 23R and 23A2, which are in the end areas of the actuating section 42 of the slide 40 and therefore no shielding to one side an adjacent contact spring noted here that the active and passive contact springs 25 and 23 in FIG.
- transverse walls or barrier walls 46 which each interact separate active and passive contact springs each an approximately semicircular section 49 in line with the round contour of the contact pieces.
- this cutout 49 is a movable contact piece 26 of the active contact springs 25 out.
- This allows the active Contact spring itself close to the barrier wall 46 or one locking rib 50 protruding from the barrier wall.
- the slider forms from the side walls 44 inwardly protruding actuating lugs 52 which are in different Height of the active working contact springs or activate the active normally closed contact springs.
- the active ones Contact springs are each within the window 47 arranged and between the respective locking rib 50 and the associated actuating nose 51 or 52 performed with tight play. This will also when welding a contact all other active contact springs against another switching operation blocked.
- the assembled is first Magnet system inserted into the recess 11 of the base body 1, the armature spring 38 between the yoke leg 33 and is attached to the base body.
- the slider 40 with its connecting section 41 is attached, the return leg 39 of the armature spring 38 in the openings 41a of the slide are hooked in.
- the anchor itself is stored on the yoke leg 33 and with its extension 37a in the opening 41b of the slide 40 hooked.
- the contact springs After installing the slide 40, the one with the longitudinal partition 43 on the longitudinal wall 13 and with the longitudinal walls 44 on the Side walls 12 of the base body 1 sits, the contact springs assembled. All contact springs are thereby corresponding windows 47 and 48 of the slide through in the chambers 15 of the base body inserted and in the slots 16 attached. All fixed contact carrier 21 with the passive contact springs 23 are constructed identically and straight, so that it is inserted into the base body perpendicular to the base plane can be. Also all active contact springs 25 with their contact spring carriers 22 are constructed identically and straight, so that regardless of their function as work contact springs 25A1, 25A2 or normally closed contact springs 25R vertical to the base level through the associated window 47 of the slide can be used. The slider 40 becomes this Purpose against the bias of the armature spring 38 in one Held middle position.
- the actuating lugs 52 are for the active normally closed contact springs 25R much higher with respect to the Base plane as the actuating lugs 51 for the active working contact springs 25A1 and 25A2. This is the force-displacement translation in the work contacts and the rest contacts differently. Since the magnet system is in a closed position Condition, that is, when the anchor is tightened or almost tightened, is strongest while when the anchor has dropped out the force of the large air gap increases slowly, normally ensured by the dimensioning of the magnet system be that the magnet system also at the beginning of Anchor suit movement applies enough force to make the normally closed contacts to actuate in the direction of the opening and the restoring force to overcome the anchor spring.
