Power connection apparatus having integrated surge arrestor

DETAILED DESCRIPTION I claim: 1.
A power line unit having a least two power leads, an insulating shell encasing said power leads, said shell including a sidewall arrestor opening exposing said power leads, an arrestor unit secured within said opening to form an exterior exposed wall and secured to the edges of said opening to close said opening and including an arrestor block within said opening in opposed operative relation to said exposed leads, and said arrestor unit having a ground connection secured to said arrestor block.
2.
The power line unit of claim 1 including at least three power leads in a substantially common plane and having the two outer leads constituting said two exposed leads and being separated by an insulation ledge encasing the central lead.
3.
A power line unit including at least three power leads in a substantially common plane, an insulating shell encasing said power leads, said shell including a sidewall arrestor opening exposing the two outer leads constituting said two exposed leads and being separated by an insulation ledge encasing the central lead, an arrestor unit including a mounting plate secured to the outer portion of said shell and closing said opening, an arrestor block secured to said plate and projecting into said opening into abutting engagement with said insulation ledge to separate the chambers surrounding said exposed leads, and means sealing said plate to said shell to form a liquid tight arrestor chamber.
4.
The power line unit of claim 1 wherein said arrestor unit includes a metal conducting plate secured within said opening and defining the exterior exposed wall and constituting said ground connection, said arrestor block being affixed to said plate.
5.
The power line unit of claim 1 wherein said arrestor unit includes a mounting plate secured to the outer portion of said shell and said arrestor block being formed of silicon carbide, an electrically conductive adhesive connecting said arrestor block to said plate and projecting into said opening, means sealing said plate to said shell to form a liquid tight arrestor chamber
