Anode and capsule assembly for automotive cathodic protection

摘要

A square blocked anode with first and second opposite flat faces and rectangular sidewalls joining the flat faces has a diagonal hole formed between one sidewall and a second face of the anode. Insulation is stripped from a distal end of a multiple strand insulated wire lead and the stripped end is inserted through the sidewall into the diagonal opening. Wire strands which emerge from the opening in the second surface of the anode are spread around the opening and solder may be applied to the spread strands. The square anode is fitted within a capsule having a square body with inner walls similar to the anode and slightly larger than corresponding surfaces of the anode. The insulated wire lead which emerges from the diagonal opening in a sidewall engages an inner surface of the capsule and an opposite sidewall of the anode engages an opposite inner surface of the capsule in friction fit, holding the anode in the capsule after the anode with the emerging wire lead are pressed in the capsule. The wire lead extends across the second surface of the anode within the capsule and emerges through an opening in the opposite sidewall of the capsule. A square flange extends around the open end of the capsule. An adhesive is spread over the surface of the flange and the first surface of the anode which is centered within the flange surface.
