Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
198 words
An electric contact arrangement comprising a plurality of contacts mounted within a housing of insulating material closed on one side by an insulating side member formed with apertures aligned with respective contacts within the housing for insertion of pins through the apertures, each contact comprising a base strip portion having a pair of contact arms bent up one from each side and convergent towards their free ends, an aperture being formed in the base strip portion for passage of a pin through the contact aperture to engage between the arms, the base strip portion being disposed against a sealing diaphragm of resilient sealing material positioned between the base strip and the one side of the housing, the contact apertures of the plurality of contacts being aligned with respective apertures in the housing one side and the contact arms extending away from the housing one side such that on inserting a pin through an aperture in the one side of the housing to pierce the diaphragm, penetrate the associated contact aperture and engage between the contact arms, resilient sealing material of the diaphragm is trapped between the pin and the surrounding wall of the aperture in the base strip.
