Abstract
Abstract A connector socket adapted to be retained in an opening of a printed circuit board to receive a contact pin or the like, has a tubular body portion receivable in the circuit board opening, and has an external shoulder that acts as a stop during the inserting movement. The body portion contains a spring contactor for engagement with any suitable contact pin. For retaining the connector socket securely in the circuit board, it has at least one external resilient spring retainer finger but preferably two fingers which extend lengthwise of the tubular body and engage the circuit board at the opening thereof. The retainer fingers are movable independently of the body, but are formed integrally therewith. The connector socket is constituted as an economical-to-produce metal stamping, which can have very close tolerances, and the body portion has external recesses in which the extremities of the spring fingers are nested, such extremities being inwardly bent to eliminate their interfering with the insertion of the body in the board.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
206 words
An electrical connector receptacle for insertion in an opening of a circuit board for electrical engagement with a pin terminal, comprising: a tubular metal member having a first section, a second section and a third section, said first section defining an enclosed tip, said second section defining a body of larger diameter than said first section, said third section defining a flared end constituting a stop engageable with the circuit board after the tubular metal member has been inserted in the opening in the circuit board, said flared end also defining a mouth, a beveled shoulder extending between said first and second sections, recess means in said beveled shoulder; a spring contactor member disposed within said tubular metal member for electrical engagement with the pin terminal; retainer spring means integral with said third section and extending exteriorly of and along said tubular metal member and having a bowed section for springably engaging a wall defining the opening of the circuit board to retain the receptacle within the opening and an inwardly-turned free end terminating within said recess means so that said inwardly-turned free end is movable along said recess means and prevented from catching on the circuit board during insertion of the receptacle within the opening.
Claim 2
Dependent Claim
206 words
An electrical connector receptacle for insertion in an opening of a circuit board for electrical engagement with a pin terminal, comprising: a tubular metal member having a first section, a second section and a third section, said first section defining an enclosed tip, said second section defining a body of larger diameter than said first section, said third section defining a flared end constituting a stop engageable with the circuit board after the tubular metal member has been inserted in the opening in the circuit board, said flared end also defining a mouth, a beveled shoulder extending between said first and second sections, recess means in said beveled shoulder; a spring contactor member disposed within said tubular metal member for electrical engagement with the pin terminal; retainer spring means integral with said third section and extending exteriorly of and along said tubular metal member and having a bowed section for springably engaging a wall defining the opening of the circuit board to retain the receptacle within the opening and an inwardly-turned free end terminating within said recess means so that said inwardly-turned free end is movable along said recess means and prevented from catching on the circuit board during insertion of the receptacle within the opening.
Claim 3
Dependent Claim
41 words
A connector receptacle as set forth in claim 1, wherein said retainer spring means comprises a resilient finger having a free end which is laterally displaced toward the bottom of said recess means with respect to the remainder of the finger.
Claim 4
Dependent Claim
53 words
A connector receptacle as set forth in claim 1, wherein said retainer spring means comprises two resilient fingers disposed at opposite sides of the tubular metal member, said tubular metal member having two external recess means disposed respectively adjacent said fingers, in which recess means the free ends of the fingers are nested.
Claim 5
Dependent Claim
21 words
A connector receptacle as set forth in claim 1, wherein said retainer spring means comprises a finger having a flattened N-configuration.
Claim 6
Dependent Claim
17 words
A connector receptacle as set forth in claim 3, wherein said resilient fingers have a flattened N-configuration.
Claim 7
Dependent Claim
16 words
A connector receptacle as set forth in claim 1, wherein the recess means is essentially semi-circular.
Claim 8
Dependent Claim
36 words
A connector receptacle as set forth in claim 1, wherein the bottom wall of the recess means is flush with and a continuation of the exterior surface of the said first section of the tubular member.
Claim 9
Dependent Claim
33 words
A connector receptacle as set forth in claim 1, wherein the walls of the shoulders on opposite sides of the recess means are higher than the free end of the retainer spring means.
Claim 10
Dependent Claim
38 words
A connector receptacle as set forth in claim 1, wherein said tubular metal member is indented to form said recess means whereby it has a concave outer wall and a convex inner wall at the said recess means.
Claim 11
Dependent Claim
34 words
A connector receptacle as set forth in claim 9, wherein the inner wall formed by the indentation protrudes inwardly into the bore of the tubular metal member at the location of the recess means.
Claim 12
Dependent Claim
38 words
A connector receptacle as set forth in claim 1, wherein the wall thicknesses of the tubular metal member at its second section and at its recess means and its first section are all essentially equal to one another.
