  • Patent number: 5617066
    Abstract: The relay has a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements (21, 22, 23, 24) and is mounted on the base by means of bearing strips, the bearing strips simultaneously serving as electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of the individual parts. This structure consequently permits non-problematic, cost-effective production of the individual parts and accurate assembly without the requirement of subsequent adjustment.

  • Patent number: 5194694
    Abstract: To seal the gaps and openings in the housing of an electrical component, the outside wall of the base of the housing is provided with filling reservoirs from which lead distributing channels leading to sealing locations to be sealed by sealing compound. The distributing channels are subdivided into sub-channels by centrally extending distributing ribs so that the sub-channels provide an increased capillary action for sealing compound deposited into the filling reservoirs.

  • Patent number: 5065127
    Abstract: A relay includes a leaf spring for bearing an armature at a free end of a yoke, the leaf spring forming, first, a bearing plate lying against the yoke and, second, a pull-back spring applied thereto in one piece. The pull-back spring has a first section cut free from the middle of the bearing plate so that the bearing plate is subdivided into two plate sections on which the armature rests only at its lateral regions on its bearing edges. Further, the pulled-back spring as its free end cut arcuately roughly symmetrical to the center axis of the bearing plate to exert an approximately symmetrical pull-back force on the armature.

  • Patent number: 4818965
    Abstract: In a relay including an angle yoke (5), a flat armature (8) and a thin base plate (6) applied to the outside of the yoke, which forms a bearing groove (7) for the armature (8) together with the rectangularly cut end face (5a) of the yoke. The armature is pushed into the bearing groove by a predetermined particularly shaped bearing spring (15) and acted upon by a reset rotational moment. Through this arrangement, a space saving and cost-efficient construction of the relay with constant armature bearing force is obtained as well as low response efficiency.

  • Patent number: 4740769
    Abstract: A relay includes a spool, or coil (3 and 4), and a yoke (5) next to the spool. In front of the spool, an armature (8) that activates a contact spring (16) is accomodated in a contact space positioned upstream in one of the free sides of the armature. The contact spring has an initial leg (16a) extending straight across the overall width of the relay and a U-shaped second leg (16b) mounted on the first. The free end of the U-shaped spring leg (16b) operates in conjunction with two reciprocal-contact elements (13 and 14). The generally Y shape results in a contact spring (16) with a maximum possible free length and hence a low spring constant, meaning a low relay-response output, while retaining the prescribed compact design.
