Connector receptacle for printed circuit boards

Claim 2

A connector receptacle for insertion in an opening of a printed circuit board to receive a contact pin of a cooperable connector, comprising in combination: (a) a tubular shell adapted to fit into said opening, said shell having at one end a leading portion of reduced diameter adapted to loosely fit into and enter the opening in a circuit board, and having at its opposite end an open mouth portion and external shoulder means at said mouth portion, constituting a stop which is engageable with the circuit board after the shell has been inserted therein, (b) a spring contactor constituting a piece separate from the shell, said contactor being disposed in said shell and adpated for engagement with said contact pin of the cooperable connector, and (c) an external resilient bowed spring retainer finger on the shell, extending lengthwise thereof along its exterior and toward the leading end portion thereof, for engagement with the circuit board to maintain the shell in the opening thereof against inadvertent dislodgement therefrom, (d) said retainer finger having a free end which terminates short of the extremity of said leading end portion of the shell and is adapted to enter the opening in the circuit board ahead of the rest of the finger, and being integral with the shell and movable independently of the shell, and further being integrally connected to the open mouth portion of the shell, (e) said free end being disposed at a location beyond the board when the receptacle is fully seated.

Claim 3

A connector receptacle as set forth in claim 1, wherein: (a) there is an additional resilient finger disposed at the opposite side of the shell, having an extremity which terminates at a location intermediate the ends of the shell.

Claim 4

A connector receptacle as set forth in claim 2, wherein: (a) said additional resilient finger is integral with the shell.

Claim 5

A connector receptacle as set forth in claim 2, wherein: (a) said resilient fingers have a flattened N-configuration.

Claim 6

A connector receptacle as set forth in claim 1, wherein: (a) said resilient finger has a flattened N-configuration.

Claim 7

A connector receptacle as set forth in claim 1, wherein: (a) said shell has an external annular shoulder intermediate its ends, (b) said free end being provided with an angular offset disposed closely adjacent said annular shoulder.

Claim 8

A connector receptacle as set forth in claim 1, wherein: (a) said resilient finger at a point intermediate its ends is adapted to engage the exterior of the shell.

Claim 9

A connector receptacle for insertion in an opening of a printed circuit board to receive the contact pin of a cooperable electrical component, comprising in combination: (a) a one-piece tubular shell adapted to fit into said opening, said shell being completely closed at one end and having an open mouth portion at its other end in which the said contact pin can be inserted, all parts of said shell being integral with one another, (b) a separate and distinct spring contactor disposed in said shell, said contactor being held captive therein and adapted for engagement with said contact pin, and (c) an external resilient spring retainer finger integral with and connected to the shell at its mouth portion, said finger extending lengthwise thereof toward the closed end of the shell for a fractional portion of the length of the body of the shell and being adapted for engagement with the circuit board to maintain the shell in the opening thereof against inadvertent dislodgement therefrom, prior to soldering of the connector receptacle into the opening of the board, (d) said spring retainer finger being movable independently of the body of the shell and having a yieldable non-linear portion which engages the walls of said opening and shifts radially inward during insertion of the connector receptacle.

Claim 10

A connector receptacle for insertion in an opening of a printed circuit board to receive the contact pin of a cooperable electrical component, comprising in combination: (a) a one-piece tubular shell adapted to fit into said opening, said shell being completely closed at one end and having an open mouth portion at its other end in which the said contact pin can be inserted, all parts of said shell being integral with one another, (b) a separate and distinct spring contactor disposed in said shell, said contactor being held captive therein and adapted for engagement with said contact pin, and (c) an external resilient spring retainer finger integral with and connected to the shell at its mouth portion, said finger extending lengthwise thereof toward the closed end of the shell for a fractional portion of the length of the body of the shell and being adapted for engagement with the circuit board to maintain the shell in the opening thereof against inadvertent dislodgement therefrom, prior to soldering of the connector receptacle into the opening of the board, (d) said spring retainer finger being movable independently of the body of the shell and having a yieldable non-linear portion which engages the walls of said opening and shifts radially inward during insertion of the connector receptacle.

Claim 11

A connector receptacle as set forth in claim 8, wherein: (a) said shell has an annular shoulder intermediate its ends, (b) said finger having a free tip portion, (c) the tip portion of said finger having an offset extending inwardly toward the body of said shell, and being adapted to nest against the said shoulder so as to reduce the likelihood of the finger being inadvertently caught and bent upwardly toward the open mouth of the shell during insertion of the connector receptacle into the opening of the printed circuit board.

Claim 12

A connector receptacle for insertion in an opening of a printed circuit board to receive the contact pin of a cooperable electrical component, comprising in combination: (a) a tubular shell adapted to fit into said opening, said shell being completely closed at one end and having an open mouth portion at its other end in which the said contact pin can be inserted, (b) a separate and distinct spring contactor disposed in said shell, said contactor having a mouth and being adapted for engagement with said contact pin, (c) a pair of lugs integral with the shell, said lugs having bent over portions extending over the mouth of the contactor so as to hold the latter captive in the shell at all times, (d) a pair of external resilient spring retainer fingers integral with and connected to the shell at substantially opposite locations of its mouth portion, said fingers extending lengthwise of the shell and on opposite sides thereof and toward the closed end of the shell for a fractional portion of the length of the shell body and being adapted for engagement with the circuit board to maintain the shell in the opening thereof against inadvertent dislodgement prior to soldering of the connector receptacle into the opening of the board, (e) said spring retainer fingers being movable independently of the body of the shell and each having a yieldable non-linear portion which engages the walls of said opening and shifts radially inward and toward the other finger during insertion of the connector receptacle into the circuit board.

Claim 13

A connector receptacle for insertion in an opening of a printed circuit board to receive the contact pin of a cooperable electrical component, comprising in combination: (a) a tubular shell adapted to fit into said opening, said shell being completely closed at one end and having an open mouth portion at its other end in which the said contact pin can be inserted, (b) a separate and distinct spring contactor disposed in said shell, said contactor having a mouth and being adapted for engagement with said contact pin, (c) a pair of lugs integral with the shell, said lugs having bent over portions extending over the mouth of the contactor so as to hold the latter captive in the shell at all times, (d) a pair of external resilient spring retainer fingers integral with and connected to the shell at substantially opposite locations of its mouth portion, said fingers extending lengthwise of the shell and on opposite sides thereof and toward the closed end of the shell for a fractional portion of the length of the shell body and being adapted for engagement with the circuit board to maintain the shell in the opening thereof against inadvertent dislodgement prior to soldering of the connector receptacle into the opening of the board, (e) said spring retainer fingers being movable independently of the body of the shell and each having a yieldable non-linear portion which engages the walls of said opening and shifts radially inward and toward the other finger during insertion of the connector receptacle into the circuit board.
