ABSTRACT:
Waterproof electrical enclosures for the encapsulation of electrical and electronic components have a box-like base part to be fixed to a support surface by screws or like mounting fixtures and a sealing cover held to the base part by special fasteners located in special mounting points in the corners of the enclosure. Each mounting point has a single channel extending into the base part which in cross-section size corresponds to the size of the head of a mounting fixture and narrows to an aperture for the shaft of the mounting fixture in the bottom of the base part. There are fasteners fitted through the cover, each with a connection piece thereof larger than the shaft of the fastener, such piece being fixable in the top of a base part channel to connect the cover fastener to the base part.
