Definitions

the present invention is in the field of encapsulated switches and relates to gas-filled encapsulated relays, in particular a plastic encapsulated relay for mounting on printed circuit boards.
Plastic-encapsulated relays for pressure circuit boards are known, including those with a gas filling, an inert gas which is usually introduced to increase the contact reliability and which is introduced via special openings which can be closed after filling.
an inert gas which is usually introduced to increase the contact reliability and which is introduced via special openings which can be closed after filling.
An example of this is the wash-tight relay according to DE-A-3323922.
this does not result in a significant increase in the dielectric strength.
the electronegative gas can increase the dielectric strength to a sufficient extent compared to fillings with dry air or inert gas.
the electronegative gas can increase the dielectric strength to a sufficient extent compared to fillings with dry air or inert gas.
For fillings under Normal pressure is sufficient for a plastic housing and sealed plastic encapsulation to limit leakage losses.
the coordination between the type of plastic and the gas and their sealing prevents an impermissible loss of diffusion of the electronegative gas.
a specified dielectric strength is thus maintained over the service life of the relay. Compared to known relays, it is thus possible to produce smaller relays with the same high dielectric strength or relays of the same size with higher dielectric strength.
inert gas primarily serves to ensure an uncontaminated starting atmosphere.
Inert gas such as nitrogen or argon, diffuses through the plastic just as quickly as water vapor or oxygen.
the plastic acts as a microfilter for the outside air diffusing into the interior of the housing to compensate, so that there is no contamination.
electronegative gases have up to five times higher relative dielectric strength than air. Even a gas with a relative dielectric strength of 2.5 gives a sufficient increase in dielectric strength in the sense of the invention.
the electronegative gas must remain in sufficient concentration in the interior of the housing.
plastics are selected, the structure of which almost completely restrains the molecules of the electronegative gas.
the molecules of the electronegative gases are larger than those of the air and the inert gases, which makes the range of suitable ones Plastics expanded.
the composition of the gas filling changes after the manufacture of the relay, due to the diffusion properties of all gases in relation to the plastics used, but the concentration of electronegative gas remains sufficiently high to ensure a correspondingly specified dielectric strength.
a proven, well-studied and therefore preferred electronegative gas is sulfur hexafluoride, SF6. It can be used in the form of technically pure SF6 as the sole filling gas.
a mixture of gases can improve e.g. B. bring about temperature behavior.
One of the gases of such a mixture is in turn preferably SF6.
the measures envisaged in combination therefore make it possible to produce a relay with improved properties with regard to dielectric strength in a similar manner to hitherto inexpensively. This can either increase the dielectric strength compared to filling the relay interior with dry air or an inert gas are observed without having to change the relay dimensions, or smaller relay dimensions can be realized with unchanged dielectric strength.
