Definitions

  • the invention relates to an armature bearing for a folding armature relay, consisting of a yoke, an armature mounted on an end section of the yoke and an armature retaining spring which carries at least one switching contact and which is mechanically connected to the armature.
  • Such an anchor bearing is previously known from DE 43 20 831 C1.
  • special bearing points are provided between the armature and the yoke, in which either the armature or the yoke has inclined contact surfaces.
  • a displacement of the armature is converted into a rotary movement, with the center of the switch contact as the center of rotation, so that the switch contacts lying opposite one another do not move against one another. This avoids contact misalignment, which leads to increased contact erosion, which greatly affects the service life of the relay.
  • a disadvantage of this well-functioning anchor bearing is that the stamping or stamping of such an anchor bearing is relatively costly, especially since not too high manufacturing tolerances are permitted on the anchor and on the yoke.
  • the anchor holding spring forms at least two integrally molded spring hooks, each of which a first section lies flat against the top of the anchor and each of which has a second section, which is approximately at right angles to the respective first section and around the anchor is bent around and rests almost flat on the outside of the yoke when the armature is in the rest position and that the armature retaining spring also integrally forms a return spring which also has an approximately right-angled bend with respect to the longitudinal direction of the armature.
  • the anchor bearing according to the invention is advantageous in many ways.
  • a relay with an armature bearing according to the invention is particularly simple and inexpensive to produce, since it consists of particularly few individual parts, since the flat spring connected to the armature integrally forms both the switch contact spring and the return spring for the armature and also the spring hooks for the armature bearing.
  • additional components that apply spring forces are not required.
  • both the yoke and the armature can be particularly simple and in particular have no special embossments or cuts. This makes the production of these components very simple and inexpensive, especially since their flatness tolerances can be quite large.
  • the position of the switch contacts in relation to one another in the armature bearing arrangement according to the invention is only determined by the flat spring, but not by the armature, as a result of which the chain of tolerances which is responsible for the contact offset is shortened.
  • the armature mounting enables the armature and the armature retaining spring connected to it to be able to move freely relative to the fixed contacts in a defined frame, the freedom of movement not being limited mechanical end stops, but is damped by spring action.
  • the free end portion of the return spring is fixed to a connection terminal and that the current supply to the movable switch contacts is carried out via the return spring, since this causes the load current to be directly supplied to the switch contacts over a wide and low-resistance section of the armature retaining spring, so that additional means favoring the power line, such as e.g. B. braided copper strips or the like can be omitted.
  • additional means favoring the power line such as e.g. B. braided copper strips or the like can be omitted.
  • the restoring force of the return spring and thus also the minimum tightening voltage can be influenced in a simple manner by bending the connecting terminal connected to the return spring.
  • Figure 1 shows the schematic diagram of an anchor bearing according to the invention with omission of all parts of the folding armature relay not required for explanation.
  • a magnet coil (6) and an L-shaped yoke (3) placed around the magnet coil (6) can be seen.
  • the armature (1) is mounted in such a way that an end section of the armature (1) rests on an end face of the yoke (3), without any interlocking means being provided on the yoke (3) and armature (1).
  • the anchor retaining spring (2) is riveted to the anchor (1).
  • the armature retaining spring (2) forms in one piece two molded spring hooks (4), of which a first section (4a) lies flat against the top of the armature (1) and a second section (4b), which is approximately at right angles to the each first section (4a) and around the armature is bent, and rests almost flat on the outside of the yoke (3) when the armature (1) is in the rest position.
  • the armature retaining spring (2) also forms in one piece a return spring (5) which also has an approximately right-angled bend with respect to the longitudinal direction of the armature (1), the end section of the return spring being fixed at a suitable point (not shown in FIG. 1).
  • This point can advantageously be a connecting terminal, via which the load current to be switched can be applied to the at least one switching contact (7).
  • the principle of the armature bearing according to the invention is that the armature is not supported by rigid mechanical limitations, but by different spring forces of the armature retaining spring (2).
  • the return spring (5) generates a force that drives the armature back from the magnet coil (6), as well as a force component in the longitudinal direction of the armature (1). Due to the balance of these forces, the armature (1) is always returned to its starting position.
  • FIG. 2 shows a fully assembled relay which has an armature bearing according to the invention.
  • the relay is mounted on a base plate (8) and has a plurality of connection terminals which form flat plugs (9) on the underside of the base plate (8).
