Abstract
Abstract Electrical connectors having a ''''monodielectric'''' construction in which the configuration of engaging end surfaces of contactsupporting dielectric members and the characteristic of the material of the members are such as to provide a reliable fluid seal while providing firm mechanical contact support. Specific features relate to the provision of risers on one dielectric member which telescope in the ends of passages on the other, to the use of a semihard material, preferably a polymer material operable continuously at high temperatures, to the elimination of air pockets so as to provide high corona resistance, and to the use of a wave spring arrangement for obtaining optimum pressure engagement. Contact retention members are provided having spring fingers of a hard material engageable with contacts of soft material, permitting removal and replacement of the contacts without destruction of the retention member or the dielectric.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
263 words
In an electrical connector, a pair of dielectric members, a pair of hollow shells supporting said pair of elongated dielectric members therewithin and arranged to be secured together to hold end surfaces of said dielectric members together in pressure engagement, said pair of dielectric members having one or more pairs of aligned passages therethrough, contacts supported in said passages and adapted to be brought into mating electrical contact when said end surfaces are brought together in pressure engagement, said end surfaces of said pairs of dielectric members including planar portions of substantial areas in surrounding relation to said passages, said end surfaces further including a frustoconical integral riser about one end of a passage of each pair of aligned passages to telescope within a generally circular end portion of the other passage and to engage the dielectric member of said other passage along a continuous unbroken line of engagement, the diameter of said generally cylindrical surface having a value between the values of the minimum and maximum diameters of said frustoconical surface, said dielectric members being composed of homogeneous monodielectric material, and locking means for securing said dielectric members firmly together to deform the base portion of said riser and the portion of its mating dielectric member engaged by said riser, and to maintain said planar portions firmly engaged when said shells are secured together to prevent the formation of fluidentrapping pockets, an outer surface portion of said riser and an inner surface portion of said end portion of said other passage being in pressure sealing engagement when said shells are secured together.
Claim 2
Dependent Claim
263 words
In an electrical connector, a pair of dielectric members, a pair of hollow shells supporting said pair of elongated dielectric members therewithin and arranged to be secured together to hold end surfaces of said dielectric members together in pressure engagement, said pair of dielectric members having one or more pairs of aligned passages therethrough, contacts supported in said passages and adapted to be brought into mating electrical contact when said end surfaces are brought together in pressure engagement, said end surfaces of said pairs of dielectric members including planar portions of substantial areas in surrounding relation to said passages, said end surfaces further including a frustoconical integral riser about one end of a passage of each pair of aligned passages to telescope within a generally circular end portion of the other passage and to engage the dielectric member of said other passage along a continuous unbroken line of engagement, the diameter of said generally cylindrical surface having a value between the values of the minimum and maximum diameters of said frustoconical surface, said dielectric members being composed of homogeneous monodielectric material, and locking means for securing said dielectric members firmly together to deform the base portion of said riser and the portion of its mating dielectric member engaged by said riser, and to maintain said planar portions firmly engaged when said shells are secured together to prevent the formation of fluidentrapping pockets, an outer surface portion of said riser and an inner surface portion of said end portion of said other passage being in pressure sealing engagement when said shells are secured together.
Claim 3
Dependent Claim
31 words
In an electrical connector as defined in claim 1, each of said dielectric members being of material having a modulus of elasticity on the order of 300,000 pounds per square inch.
Claim 4
Dependent Claim
36 words
In an electrical connector as defined in claim 1, each of said dielectric members being of a polymer material having a basic polymer structure consisting of phenyl and biphenyl units linked by oxygen and sulfone groups.
Claim 5
Dependent Claim
66 words
In an electrical connector as defined in claim 1, said locking means including a coupling ring, spring means acting between said coupling ring and one of said pair of shells, said coupling ring and the other of said pair of shells being adapted for threaded interengagement to cause said spring means to exert a force urging said end surFaces of said dielectric members into pressure engagement.
Claim 6
Dependent Claim
46 words
In an electrical connector as defined in claim 4, said coupling ring and said other of said pair of shells having interengaging stop surfaces to limit relative movement and to cause a predetermined engagement force to be inserted between said end surfaces of said dielectric members.
Claim 7
Dependent Claim
158 words
In an electrical connector, a dielectric member having a passage therethrough, a contact member in said passage having an annular shoulder between the opposite ends thereof, a retention member around said contact member within said passage, interengaging means between said retention member and said passage for locking said retention member against movement along said passage, said retention member being of a hard spring metal and having spring finger means with shoulder means lockingly engaging said contact member at its said annular shoulder to retain said contact member, said contact member being of a soft conductive metal relative to said metal of said retention member, and said shoulder of said contact member being inclined toward the end portion of said contact member to guide said finger means to ride up onto and cut into said inclined shoulder when said contact member is forcibly driven out from said retention member without damage to said retention member or said dielectric member.
Claim 8
Dependent Claim
158 words
In an electrical connector, a dielectric member having a passage therethrough, a contact member in said passage having an annular shoulder between the opposite ends thereof, a retention member around said contact member within said passage, interengaging means between said retention member and said passage for locking said retention member against movement along said passage, said retention member being of a hard spring metal and having spring finger means with shoulder means lockingly engaging said contact member at its said annular shoulder to retain said contact member, said contact member being of a soft conductive metal relative to said metal of said retention member, and said shoulder of said contact member being inclined toward the end portion of said contact member to guide said finger means to ride up onto and cut into said inclined shoulder when said contact member is forcibly driven out from said retention member without damage to said retention member or said dielectric member.
