Definitions

  • connection conductors are made of very soft material, their own noise transmission is reduced, but in this case the connection conductors can not stably hold the inner housing at a distance from the outer housing. There is therefore the danger that the inner housing, for example, after external shocks at least on one side rests on the outer housing and transmits the switching noise directly to the outer housing.
  • EP 0 838 829 A2 which is an earlier filed application with respect to a noise reduced relay, a gap between an inner casing and an outer casing of the relay is filled with an amorphous insulating insulating material having a high internal friction, wherein the Insulating material is powdered or made of permanently elastic material.
  • a pulverulent insulating material is introduced into the intermediate space through an inner opening via a nozzle.
  • the aim of the present invention is to develop a relay with a double-walled housing structure according to the type mentioned so that the noise transmission to the outside is further reduced and that this noise reduction is also reliably maintained.
  • insulating material is thus arranged in the intermediate space between the inner housing and the outer housing in the form of an intermediate cap, so that the inner housing can not come into contact with the outer housing on either side.
  • the connecting conductors which are preferably designed as strands, can be so soft that they also do not transmit vibrations.
  • the intermediate cap itself is preferably made of elastomer.
  • the end sections of the connecting conductors are preferably held in passages of a damping frame.
  • a damping plate which is also made of elastomer or a similar material, ensure the distance between the inner housing and the outer housing.
  • the outer housing preferably consists of an outer cap and a base.
  • the base own external connections, for example in the form of tabs, which are anchored in the material of the base by embedding or insertion.
  • these external terminals are then connected to the ends of the connecting conductors, which can be done with conventional joining techniques, preferably by welding. Further embodiments are specified in the subclaims.
  • the tabs 7, which are injected in the present example in the material of the base 5, are connected via flexible connecting conductors in the form of strands 8 with the inner terminals 3, which extend substantially along the outside of the inner housing 1. They are each bent at one end 8a in the region of the inner terminal side 2 at right angles to the inner terminals 3 and connected thereto, for example soldered. With their opposite ends 8b, which are compressed like the first-mentioned ends 8a, the strands 8 are guided by a damping frame 9, bent at the bottom and connected with angled connecting tabs 7a of the tabs 7, preferably welded.
  • the damping frame 9 is also made of elastic plastic, preferably an elastomer. This damper frame 9 holds during mounting the strands 8 in the desired position and also prevents the transmission of vibrations to the outer housing, ie on the Sokkel.
  • an intermediate cap 10 is placed, which consists of elastic plastic, preferably elastomer, and ensures a predetermined distance and a sound decoupling between the inner housing 1 and the outer cap 4.
  • the intermediate cap 10 has recesses 11 in the region of the inner connections 3, so that no vibrations are transmitted in this area as well.
  • it has in the region between the inner terminals 3 each to the inner housing projecting lugs 12 which press on the connection side 2 of the inner housing.
  • These lugs 12 opposite also a damping plate 13 is provided in the area between the external terminals or within the damping frame 9, which also consists of elastomer or other elastic plastic.
  • the inner housing of the relay is clamped after the engagement of the outer cap 4 to the base 5 between the elastic lugs 12 and the elastic damping plate 13; it is held in this way on all sides at a distance from the outer housing, but decoupled with respect to the transmission of sound vibrations.
  • the intermediate cap 10 has on its inner side projecting reinforcing ribs 14 which each extend between the individual connecting conductor 8. They prevent the strands or individual stranded fibers touching each other and could cause a short circuit.
  • resistors 15 are shown, which can be connected in parallel with the relay coils.
  • upstanding ribs 16 are formed on the base, which have slots 17 for receiving the resistor terminals 15a.
  • the terminals 15a are welded in a known manner on tabs 7a of the tabs 7.
