Abstract
A lampholder device of the submersible type, characterized in that the lampholder itself is placed inside an outer rubber cover, which has two consistent sealing points: the first, at the point of passage of the connection cable, thanks to a neck of the rubber part which, once the cable is introduced, is pressed against it by the clamping of a surrounding collar and the second, located at the opposite end, thanks to a flange formed therein, with a plurality of closing lips that normally make unforced contact with the neck of the lamp when it is placed in the lampholder, closing lips that can be applied with greater force against the body of the lamp thanks to the compression of the material by means of a press-tow that surrounds the lamp. This part of the envelope and which is capable of compressing said material on three sides, to cause its elongation in the desired radial direction.
