Abstract
Abstract An electrical cable connector of the multi-contact type wherein pin contact members of a male plug component engage and make electrical connection with corresponding spring finger contact members of a female receptacle, the pin and spring finger members each being threadably secured in a wire lead connecting base portion mounted in an insulating matrix in the plug and sockets components, respectively. The base portion for both the pin and spring finger members can be identical, thus providing a common base in a three piece contact system wherein a common base will receive either the male pin or the female spring finger members and allow ready removal of the contact members for replacement without disconnection of lead wires in instances of damage such as might be caused by dropping or rough handling of the connector.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
83 words
An electrical connector comprising a housing of rigid protective material having an open face portion, a yieldable matrix material protectively contained within said housing, a plurality of current carrying contact members extending partially within and extending from said matrix material comprising active electrical contact portions accessible at said face portion, and corresponding base portions supported at least in part in and by said elastomeric matrix material and projecting slightly from said matrix material and on which said active contact portions are threadably secured.
Claim 2
Dependent Claim
83 words
An electrical connector comprising a housing of rigid protective material having an open face portion, a yieldable matrix material protectively contained within said housing, a plurality of current carrying contact members extending partially within and extending from said matrix material comprising active electrical contact portions accessible at said face portion, and corresponding base portions supported at least in part in and by said elastomeric matrix material and projecting slightly from said matrix material and on which said active contact portions are threadably secured.
Claim 3
Dependent Claim
27 words
An electrical connector as set out in claim 1 wherein said contact members have lead wires connected thereto by electrical connection directly to their respective base portions.
Claim 4
Dependent Claim
24 words
An electrical connector according to claim 2 comprising a male plug component wherein the contact members include pin contacts projecting from said face portion.
Claim 5
Dependent Claim
20 words
An electrical connector according to claim 2 comprising a female socket component wherein the contact members include spring finger contacts.
Claim 6
Dependent Claim
42 words
An electrical connector according to claim 4 wherein the spring finger contacts are protectively residenced in aperture channels through an electrically non-conductive insert of hard material retained in aligned relation by said housing on the face side of said elastomeric matrix material.
Claim 7
Dependent Claim
26 words
An electrical connector according to claim 4 wherein the base portion of said connector members are of copper and said spring finger contacts comprise beryllium copper.
Claim 8
Dependent Claim
104 words
An electrical connector formed of two mateable components, one said component comprising a plug and the other a socket, each of said components comprising a housing of rigid protective material having an open face portion, a yieldable elastomeric matrix material protectively contained as an insert within said housing, a plurality of current conducting contact members extending partially within and from said matrix material comprising active electrical contact portions accessible at said face portion, and corresponding identical base portions supported in part in and by said matrix material and projecting slightly from said matrix material and on which said active contact portions are removeably secured.
Claim 9
Dependent Claim
104 words
An electrical connector formed of two mateable components, one said component comprising a plug and the other a socket, each of said components comprising a housing of rigid protective material having an open face portion, a yieldable elastomeric matrix material protectively contained as an insert within said housing, a plurality of current conducting contact members extending partially within and from said matrix material comprising active electrical contact portions accessible at said face portion, and corresponding identical base portions supported in part in and by said matrix material and projecting slightly from said matrix material and on which said active contact portions are removeably secured.
Claim 10
Dependent Claim
60 words
An electrical connector as set out in claim 7 wherein each of said connector components have lead wires of a cable electrically connected to contact members thereof, said lead wires being connected directly to the base portions of said members, thereby permitting removal and replacement of active contact portions of said contact members without disconnection of said connected lead wires.
Claim 11
Dependent Claim
35 words
An electrical connector as set out in claim 8 wherein the plug component incorporates contact members comprising pin contacts threadably secured to base portions, said pin contacts projecting from the face portion of said plug.
Claim 12
Dependent Claim
58 words
An electrical connector as set out in claim 8 wherein the socket component incorporates contact members comprising spring finger contacts threadably secured to base portions, said spring finger contacts being protectively residenced in aperture channels in material in the form of an insert retained in aligned relation by said housing and forming the face of said socket component.
Claim 13
Dependent Claim
26 words
An electrical connector as set out in claim 10 wherein the material forming the face of the socket component is substantially harder than said elastomeric material.
Claim 14
Dependent Claim
31 words
An electrical connector as set out in claim 10 wherein the base portions of said connector members are made of copper or brass and said spring finger contacts comprise beryllium copper.
