a low cost crimpable and sealable contact assembly including a contact member and a tubular sleeve member . the contact member is capable of being manually continuity crimped to a tip of an electrically conductive core of an electrically insulated wire . the tubular sleeve member is then deformed to hermetically seal it to the insulation on the wire , and the contact member . the hermetic seal protects the core from corrosion . this hermetic seal is particularly important where the core comprises aluminum . separating the crimping and sealing into separate operations permits them to be performed manually . the sleeve member may be comprised of polymeric material , or it may be metallic . the metallic embodiments may be mechanically or electromagnetically deformed . the polymeric sleeve members may , in addition , be heat shrunk .
