Abstract
Abstract A plug and socket type electrical connector. The socket includes a tapered pin longitudinally mounted within a sleeve to form an annular opening at one end of the socket. The mating plug includes a projection having a free end with an opening and a longitudinal slit extending through the opening. When the plug is inserted into the socket, the pin in the socket enters the opening in the free end of the plug projection and causes the projection to expand outwardly against the inside surface of the socket.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
300 words
An electrical connector assembly comprising: a socket including a sheet metal sleeve having a longitudinally extending slot therein with a forward portion on said sleeve having an opening at one end and a rear portion; a pin secured within said sleeve rear portion at a position spaced axially from said opening with a tapered free end on said pin extending into the forward portion to a position adjacent said opening and radially inwardly of said sleeve, the tapered free end of said pin including a maximum outer radial dimension spaced rearwardly from said opening to provide a first wiping zone and a longitudinal portion rearwardly of said tapered free end and dimensionally at least equal to said maximum outer dimension to provide a second wiping zone; and a plug including a forward tubular projection of smaller diameter than the internal diameter of said sleeve for movement within said sleeve of said socket and having a free end on said projection with an opening in the free end of said projection and an outer surface taper on said projection extending longitudinally toward said free end of said projection and toward the axis of said projection, said projection being longitudinally slit from said projection opening rearwardly to form a plurality of resilient contact fingers, said plug projection insertable into said sleeve opening with said projection opening receiving said pin tapered free end for expanding said resilient fingers in said first wiping zone to wipe said plug against said sleeve and further insertion of said plug engaging said fingers with said longitudinal portion in said second wiping zone to increase the wiping action between said plug and sleeve with the slot in said sleeve enabling said sleeve to expand radially in response to engagement between said plug and sleeve to accomodate said plug.
Claim 2
Dependent Claim
300 words
An electrical connector assembly comprising: a socket including a sheet metal sleeve having a longitudinally extending slot therein with a forward portion on said sleeve having an opening at one end and a rear portion; a pin secured within said sleeve rear portion at a position spaced axially from said opening with a tapered free end on said pin extending into the forward portion to a position adjacent said opening and radially inwardly of said sleeve, the tapered free end of said pin including a maximum outer radial dimension spaced rearwardly from said opening to provide a first wiping zone and a longitudinal portion rearwardly of said tapered free end and dimensionally at least equal to said maximum outer dimension to provide a second wiping zone; and a plug including a forward tubular projection of smaller diameter than the internal diameter of said sleeve for movement within said sleeve of said socket and having a free end on said projection with an opening in the free end of said projection and an outer surface taper on said projection extending longitudinally toward said free end of said projection and toward the axis of said projection, said projection being longitudinally slit from said projection opening rearwardly to form a plurality of resilient contact fingers, said plug projection insertable into said sleeve opening with said projection opening receiving said pin tapered free end for expanding said resilient fingers in said first wiping zone to wipe said plug against said sleeve and further insertion of said plug engaging said fingers with said longitudinal portion in said second wiping zone to increase the wiping action between said plug and sleeve with the slot in said sleeve enabling said sleeve to expand radially in response to engagement between said plug and sleeve to accomodate said plug.
Claim 3
Dependent Claim
26 words
The electrical connector as claimed in claim 1, wherein said pin is co-axially mounted within said sleeve, and said annular space is concentric with said sleeve.
Claim 4
Dependent Claim
49 words
The electrical connector assembly as claimed in claim 2, wherein said sleeve is fabricated of sheet metal and said pin has a base with indentations spaced axially from the free end of said pin, said pin secured in said sleeve by portions of said sleeve projecting into said indentations.
Claim 5
Dependent Claim
24 words
The electrical connector assembly as claimed in claim 2, wherein said projection is cylindrical in cross-section and said opening is co-axial with said projection.
Claim 6
Dependent Claim
14 words
The assembly as claimed in claim 1, wherein plug is fabricated from sheet metal.
Claim 7
Dependent Claim
13 words
The assembly as claimed in claim 5, wherein said sheet metal comprises bronze.
Claim 8
Dependent Claim
33 words
The electrical connector of claim 1 wherein said longitudinal portion includes a second taper longitudinally extending rearwardly and outwardly at a lesser slope than the slope of said taper with said free end.
Claim 9
Dependent Claim
40 words
The electrical connector of claim 7 wherein said longitudinal portion includes a cylindrical section rearwardly of said second taper, the combination of said first and second tapers and said cylindrical section providing three wiping zones of progressively increased wiping action.
