Definitions
- the invention relates to a noise-reduced relay with a Inner housing, from which inner connections through an inner connection side emerge with an outer housing from which External connections through an opposite to the internal connection side Exit outside connection side and with flexible connecting conductors, which are between the respective side walls of the inner housing and the outer housing extend and the internal connections with each associated Connect external connections.
- the aim of the present invention is to provide a relay with a double-walled housing structure according to the above Kind in such a way that the noise transmission to the outside is further reduced and that this noise reduction is also reliably maintained.
- this goal is achieved in that the Connection conductors the inner housing on all sides at a distance from the outer case and that the space between the inner case and the outer case with an amorphous, insulating insulation material filled with high internal friction is.
- the gap is therefore between the inner case and the outer case completely filled with an insulating material so that the inner casing in other words not in contact with the outer casing can come.
- the connecting conductor preferably as strands trained, can be so soft that they also transmit no vibrations. You just have to make a certain contribution to positioning during production of the inner housing, while after that in the Insulation filled in between the distance between the inner housing and ensures outer housing.
- a permanently elastic material for example, can be used as the insulation material Sealing material can be used.
- a powder material made of plastic which is particularly has shown good noise-reducing properties.
- different plastic materials come into consideration, such as for example polycarbonate.
- Such a filling is also environmentally friendly, because of this recycled plastic can be used.
- the grain size is preferably between 50 ⁇ m and 100 ⁇ m.
- a material must be chosen become stable at the operating temperatures of the relay is.
- the relay shown in section in Figure 1 has an inner housing 1 with a connection side 2, from the conventional Way out internal connections 3.
- This inner case is arranged at an all-round distance in an outer housing 4, which essentially consists of a cap 5 and a base plate 6 is formed.
- This base plate 6 is the inner connection side 2 opposite and forms an external connection side, emerge from the external connections 7.
- the external connections 7 are in one piece with flexible connecting conductors in the present example connected in the form of strands 8, their opposite Ends in the area of the inner connection side 2 at right angles bent towards the inner connections 3 and with these are connected.
- the strands 8 each run in the Gap between the inner housing 1 and the cap 5 of the Outer housing without touching it. You are in the present Example formed as flat strands, as shown in Figure 2.
- Figure 2a shows the flat strands 8 in unprocessed Shape
- Figure 2b these flat strands 8 with warm compressed, bent and partially trimmed ends shows.
- the external connections 7 are on the inside the base plate 6 is guided through a base frame 10, which consists of insulating material, such as permanently elastic Elastomer.
- This base frame 10 stops at Assemble the strands 8 in the desired position and prevents additionally the transmission of vibrations to the outer housing.
- the entire space is between the inner housing 1 and the outer housing 4 with powder Insulation material 11, for example a polycarbonate powder, filled.
- This powder has so much internal friction that the Inner housing 1 and the strands 8 at a predetermined distance from Outer housing are held. On the other hand, this has powder material a high insulation effect against switching noise of the Relay in the inner housing 1.
- the remaining insulation joint 12 between the bottom plate 6, the cap 5 and possibly the Base frame 10 is just like the bushings for the external connections 7 in the usual way with a permanently elastic Sealing compound or an adhesive sealed or glued.
- the flat strands 8 according to FIG. 2 (only a few shown) compressed at their ends, trimmed and bent. Then they are in plug openings 13 of the Insulated frame 10 shown in Figure 3, so that the Connection skeleton 14 shown in Figure 4 is formed.
- the insulation frame 10 has such a large inner opening 15 that the inner housing 1 according to Figure 4 through this inner opening in the pre-assembled connection skeleton 14 can be inserted.
- the Internal connections 3 are connected to the connection ends 9, for example soldered so that a pre-assembled relay with External connections 7 according to FIG. 5 are created.
- Figure 6 shows an additional end frame 16 with bushings 17 for the external connections, which in one of Figure 1 deviating design placed on the base frame 10 around this base frame made of insulating material 10 to protect the outside.
- this pre-assembled relay with the end frame 16 in the cap 5 used where that only the inner opening 15th the base frame 10 and the end frame 16 remains open.
- Insulation material 11 filled, for example via a schematically shown nozzle 17. If the entire space between the inner housing 1 and the cap 5 with the insulation material 11 is filled, the inner opening 15 with a additional cover 18 shown in Figure 9 closed.
- the remaining gaps and bushings are marked with a permanently elastic adhesive sealed or sealed.
- the housing can be closed on the external connection side through a single base plate 6 take place, in which the end frame 16 and the lid 18 are connected in part.
