  • Method for assembling a fuse holder
    Patent number: 5655292
    Abstract: A fuse holder (2) for use in electrical apparatus includes a tubular body (6) having outer and inner ends (10, 16). A first electrical contact element (22) and a mounting flange (8) are secured to the inner and outer ends, preferably using resilient retaining rings (53, 68) engaging circular grooves (52, 20; 62, 20) formed in the opposed surfaces. A tubular second electrical contact element (32) is secured within the tubular body and preferably has a flexible electrical terminal strap (24) which extends out through an opening (23) formed in the tubular body. Fluid-tight seals are provided between the inner surface (14) of the tubular body and the outer surfaces (46, 58, 30) of the first and second electrical contact elements and the mounting flange assembly by using pairs of O-rings (38, 50 and 70); an adhesive (39) is also used to secure these elements to the body.
