Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A unitary socket terminal for electronic circuits and connections, comprising: a. a cylindrical tubular body having a circumferentially continuous inner wall which defines a cylindrical inner chamber, b. a cylindrical tubular head, larger in diameter than the tubular body, formed at the upper end of said tubular body, c. said tubular head having a circumferentially continuous inner wall which defines a funnel-shaped orifice whose smaller end communicates with said inner chamber, d. said inner wall in said tubular head curving smoothly into said inner wall in the tubular body to form a continuous lead-guiding surface, e. a downwardly facing annular shoulder formed on said tubular head, f. said annular shoulder being adapted to engage a circuit or connecting element which encircles the tubular body, and g. lead-gripping means formed at the lower end of the tubular body to engage a lead guided thereinto.
Claim 2
Dependent Claim
143 words
A unitary socket terminal for electronic circuits and connections, comprising: a. a cylindrical tubular body having a circumferentially continuous inner wall which defines a cylindrical inner chamber, b. a cylindrical tubular head, larger in diameter than the tubular body, formed at the upper end of said tubular body, c. said tubular head having a circumferentially continuous inner wall which defines a funnel-shaped orifice whose smaller end communicates with said inner chamber, d. said inner wall in said tubular head curving smoothly into said inner wall in the tubular body to form a continuous lead-guiding surface, e. a downwardly facing annular shoulder formed on said tubular head, f. said annular shoulder being adapted to engage a circuit or connecting element which encircles the tubular body, and g. lead-gripping means formed at the lower end of the tubular body to engage a lead guided thereinto.
Claim 3
Dependent Claim
33 words
A unitary socket terminal in accordance with claim 1, wherein: the orifice in the tubular head has a horn-shape configuration generated by a curve rotated about the longitudinal axis of the tubular body.
Claim 4
Dependent Claim
25 words
A unitary socket terminal in accordance with claim 1, wherein: the orifice in the tubular head has a conical configuration coaxial with the tubular body.
Claim 5
Dependent Claim
36 words
A unitary socket terminal in accordance with claim 1, wherein: a. a contact terminal is formed at the lower end of the tubular body, b. said contact terminal extending downwardly from said tubular body, coaxially therewith.
Claim 6
Dependent Claim
109 words
A unitary socket terminal in accordance with claim 1, wherein: a. means for securing the socket terminal to a borehole wall formed in a printed circuit board is provided on the outer wall of the tubular body, b. said securing means comprising at least one annular rib formed on the outer wall of the tubular body, extending longitudinally of said tubular body, c. said annular rib having a downwardly facing tapered surface and an upwardly facing square shoulder and a relatively sharp edge between said downwardly and upwardly facing surfaces, d. said sharp edge being adapted to engage said borehole wall to secure the socket terminal in said borehole.
Claim 7
Dependent Claim
102 words
A unitary socket terminal in accordance with claim 1, wherein: a. means for securing the socket terminal to a borehole wall formed in a printed circuit board is provided on the outer wall of the tubular body, b. said securing means comprising a plurality of serrations formed on the outer wall of the tubular body, c. said serrations extending longitudinally of the tubular body and having downwardly facing tapered ends, upwardly facing square ends, and relatively sharp points defined by said square ends, d. said sharp points being adapted to engage said borehold wall to secure the socket terminal in said borehole.
