Abstract
Abstract A socket contact for mating with a pin contact in an electrical connector. The socket contact is provided with an electrical component-attaching section integrally formed with a receptacle section for providing an electrically efficient design. The receptacle section has a centrally disposed opening therein having an arc-arresting end portion with a diameter smaller than the diameter of the pin so that the end portion initially engages the pin and establishes an electrical connection between the pin and socket contacts. The socket contact is expandable so that the centrally disposed opening can enlarge to accommodate the pin passing therethrough into the bore.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
A socket contact for mating with a pin contact, said socket contact comprising: an electrical component-attaching section integrally formed with a receptacle section, the receptacle section having a wall forming a bore for receiving the pin contact, the receptacle section having a conductive element in the bore having a contact portion for contacting the pin contact, an arc-arresting end portion having a thickness greater than the wall forming the bore and an opening therein which opens into the bore and has a diameter smaller than an outer diameter of the pin contact for initially engaging the pin contact and establishing an electrical connection between the pin contact and the socket contact whereby the mandatory engagement and resulting electrical connection between the pin contact and the arc-arresting end portion precludes deleterious electrical arcing between the pin contact and the conductive element, and expansion means for permitting the opening to expand as the pin passes therethrough into the bore.
Claim 2
Dependent Claim
157 words
A socket contact for mating with a pin contact, said socket contact comprising: an electrical component-attaching section integrally formed with a receptacle section, the receptacle section having a wall forming a bore for receiving the pin contact, the receptacle section having a conductive element in the bore having a contact portion for contacting the pin contact, an arc-arresting end portion having a thickness greater than the wall forming the bore and an opening therein which opens into the bore and has a diameter smaller than an outer diameter of the pin contact for initially engaging the pin contact and establishing an electrical connection between the pin contact and the socket contact whereby the mandatory engagement and resulting electrical connection between the pin contact and the arc-arresting end portion precludes deleterious electrical arcing between the pin contact and the conductive element, and expansion means for permitting the opening to expand as the pin passes therethrough into the bore.
Claim 3
Dependent Claim
19 words
The socket contact of claim 1 wherein the expansion means comprises at least one slot in the receptacle section.
Claim 4
Dependent Claim
29 words
The socket contact of claim 1 further comprising an electrical connector housing portion having a receptacle therein, the receptacle section of the socket contact being disposed in the receptacle.
Claim 5
Dependent Claim
19 words
The socket contact of claim 1 wherein the expansion means comprises a plurality of slots in the receptacle section.
Claim 6
Dependent Claim
38 words
The socket contact of claim 4 wherein the end portion has a bevelled surface extending radially outwardly and in a first direction for causing the opening therein to expand when the pin contact is inserted into the opening.
Claim 7
Dependent Claim
28 words
The socket contact of claim 1 wherein the conductive element comprises a strip of spring contacts of conductive material mounted substantially around an inner wall of the bore.
Claim 8
Dependent Claim
27 words
The socket contact of claim 6 wherein the strip comprises a plurality of spaced apart cross members with a segment along their length having a reduced width.
Claim 9
Dependent Claim
141 words
An electrical socket contact for mating with a pin contact in an electrical connector, said socket contact comprising: an electrical component-attaching end; an elastically expandable cylindrical section opposite of and integral with the electrical component-attaching end, the elastically expandable cylindrical section having an annular wall forming a cavity therethrough for receiving the pin contact, the elastically expandable cylindrical section having a portion with a thickness greater than the annular wall and being adjacent to an opening with a diameter smaller than an outer diameter of the pin contact whereby an electrical connection is initially made between the pin contact and the cylindrical section in an area adjacent to the opening when the pin contact is inserted through the opening into the cavity; and a strip of spring contacts of conductive material located in the cavity of the elastically expandable cylindrical section.
Claim 10
Dependent Claim
141 words
An electrical socket contact for mating with a pin contact in an electrical connector, said socket contact comprising: an electrical component-attaching end; an elastically expandable cylindrical section opposite of and integral with the electrical component-attaching end, the elastically expandable cylindrical section having an annular wall forming a cavity therethrough for receiving the pin contact, the elastically expandable cylindrical section having a portion with a thickness greater than the annular wall and being adjacent to an opening with a diameter smaller than an outer diameter of the pin contact whereby an electrical connection is initially made between the pin contact and the cylindrical section in an area adjacent to the opening when the pin contact is inserted through the opening into the cavity; and a strip of spring contacts of conductive material located in the cavity of the elastically expandable cylindrical section.
Claim 11
Dependent Claim
34 words
The socket contact of claim 8 wherein the elastically expandable cylindrical section comprises at least one extending along at least a portion of the length of the elastically expandable cylindrical section from the opening.
Claim 12
Dependent Claim
35 words
The socket contact of claim 8 wherein the elastically expandable cylindrical section comprises a plurality of slots extending along at least a portion of the length of the elastically expandable cylindrical section from the opening.
Claim 13
Dependent Claim
27 words
The socket contact of claim 8 wherein the strip comprises a plurality of spaced apart cross members with a segment along their length having a reduced width.
Claim 14
Dependent Claim
27 words
The socket contact of claim 8 further comprising an electrical connector housing portion having a receptacle therein, the elastically expandable cylindrical section being disposed in the receptacle.
