Definitions

the invention relates to an electromagnetic flap armature relay with a contact spring attached to the armature, which has a buffer to reduce contact bounce.
Folding armature relays typically show one to four bruises when closing the normally open contact or three to ten bruises when closing the normally closed contact, with each bouncing process, depending on the switched load, strong arcs, which cause high contact wear, are ignited, thereby the life of such a relay is severely impaired.
one or more additional masses are provided on the armature of the relay as a means.
the impact damper is designed as an integrally formed on the contact spring oscillating element.
This constructively particularly simple solution according to the invention has the advantage that the contact bounce is at least significantly reduced without the relay requiring additional individual parts for this, in particular also no additional masses which increase the overall volume, since this buffer is formed here in one piece as part of the contact spring.
the vibrating element acting as a shock absorber can also advantageously be formed in a particularly simple manner by an incision made in the contact spring. This solution according to the invention is therefore particularly simple and inexpensive to implement.
a particularly advantageous embodiment of a hinged armature relay according to the invention with a shock absorber consists in that the oscillating element, starting from the contact spring end located in the region of the contacts, leads to the armature in a freely oscillating manner, which it touches or at least covers with the end not connected to the contact spring.
the mechanical kinetic energy which otherwise leads to contact bouncing, can not only be converted into vibrational energy of the vibrating element, but can also be absorbed particularly effectively by hitting or rubbing the end section of the vibrating element on the armature, that is to say converted into heat.
the contact spring (2) has one or more switching contacts (4). Two end sections (5) of the contact spring (2) are placed around the end edge of the armature (1). Another end section (6) of the contact spring (2) is bent perpendicular to the plane of the drawing and forms in one piece the return spring for the armature (1). The contact spring (2) is fastened approximately in the middle of the armature (1) by means of a rivet connection (7).
the contact spring (2) forms an oscillating element (3) which is integrally formed on the contact spring (2) or is formed by an incision (8) made in the contact spring (2).
this oscillating element (3) leads to the armature (1), which it contacts with the free end section (9) (that is, the end not connected to the contact spring) or at least covers it.
