Spark plug socket for internal combustion engines

Claim 1

Socket for spark plugs for internal combustion engines, comprising a single piece socket member of elongated configuration having connection means at one end for receiving a spark plug, and being made of thermosetting plastic, the member having a central longitudinal bore, The bore having three sides integrally connected together so that said bore will have an uninterrupted periphery defined by said sides, said bore will thus have a cross-section defined by a triangle, the bore being closed except at the other end, the bore receiving at the other end a round conductor lead in tangentially abutting relationship as to each of the three sides of the bore, the three sides of the bore thus centering the lead through said abutting relationship, the bore having a wider portion at the other end, terminating in an opening through which passes the inserted conductor lead, said lead having one end thereof adapted for connection to said connection means so that the socket is an end socket for said conductor lead; and elastomeric filler material for filling the remaining spaces between the conductor lead and the three sides of said bore for positioning the conductor lead in embedding relationship in the bore, and annularly sealing the conductor at said opening and other end.
