"Hinged armature relay"

The invention particularly relates to a clapper armature relay for use with a remotely triggered circuit breaker combination with an anchor plate, which is activated when the Excitation winding closes the magnetic circuit between a yoke and a coil core.

Such electromagnetic relays are known. The folding anchor is usually connected directly to the yoke surrounding the excitation winding by means of a cutting edge or axle bearing. This arrangement has the disadvantage that the pivot point of the hinged armature is firmly defined on the yoke and not on geometrically predetermined mechanism parts are adapted can.

The invention is based on the object of simplifying a relay of the type described above and, in particular, of achieving that, when combined with a circuit breaker, the _{fixed points and lever paths given by the release mechanism of the latter x} are taken over by a remote release provided with the hinged armature relay can. ,> \

This object is achieved in that the Anchor plate is held loosely between guides in an anchor lever, which s e i iVe ^ e i t s on a stationary from The point of intersection of the yoke with the armature plate is rotatably mounted on the axis, the armature plate on its side remote from the stationary axis from the armature lever with only little play in the working direction is guided, while it is only held laterally on the opposite side and in this way in the working direction

is free so that on the one hand it can come to rest on the yoke and on the other hand the pivoting movement of the armature lever not hindered within its functional area.

The invention has the advantage that the armature lever can be adapted to the trigger mechanism of an adjacent line circuit breaker with the same contour that its Movement sequences can be taken over directly in the event of mutual triggering. The arrangement according to the invention The hinged armature is also suitable for various other relay designs due to its simple structure. Beneficial Further developments of the invention are the subject matter of the subclaims.

The invention is based on the one figure Existing drawing explained in more detail.

The clapper armature relay is housed in a merely indicated housing 1, which has the same contour as a adjacent circuit breaker, not shown. Fixed in the housing is a known way trained excitation winding 2 with a coil core 3 and a yoke 4 serving as a magnetic yoke the end faces 3a and 4a of the coil core or of the yoke is an armature plate 5 ″ ″ ″ to be described in more detail below Way loosely in an anchor lever 6; held, in turn mounted pivotably on an axle 7 fixed to the housing is. The armature lever is provided with transmission means, for example a pin 8, which passes through an opening 1a can intervene in the mechanism of the adjacent miniature circuit breaker in the housing. The excitation winding is out on terminals 2a, wherein in the circuit / * a self-breaker contact 9 is connected. The mecha- • niche control of the self-intruder contact is not shown further.

The armature lever, whose axis of rotation 7 is far outside the The intersection of yoke 4 and armature plate 5 is located approximately parallel to the armature plate on the field winding remote side guided lever part 6a, which is provided with groove-shaped guide strips 6b or 6c- -The? Guide strips run parallel to the direction of the axis 7 and hold the appropriately designed as a rectangular part Anchor plate on the side with sufficient play. Only in the working direction it is necessary that the from the axis 7 more distant guide bar 6b holds the anchor plate with little play. But this is not jammed but can still move loosely. On the opposite side, the guide bar 6c actually takes over only the lateral guidance of the armature plate, because its movement in the working direction of the relay is limited here on the one hand by the protruding opposite the guide bar 6c End face 4a of the yoke and on the other hand by the lever part 6a itself. The lever part 6a must be of the Armature plate 5 step back so far that when the armature lever 6 is pivoted within its predetermined functional range, the armature plate 5 abuts smoothly the end faces 3a and 4a is possible without jamming.

When the field winding flows through it, the before the End face 4a of the yoke located - as shown - or already adjacent anchor plate tightened in the working direction and then swivels in front of the end face 3a of the coil core. Here is on the guide bar 6b of Lever 6 is carried along with almost no play and its pivoting movement controls further trigger mechanisms directly.
