Board to board electrical connector with height adjustment

Claim 1

A surface mountable electrical connector adapted for mounting on the surface of a printed circuit board, said circuit board having contact elements on the surface thereof, comprising, a connector housing having a plurality of terminals arranged at regular intervals for electrically and mechanically securing to contact elements on the surface of the printed circuit board, the terminals defining a slot to receive an edge of a printed circuit card, the housing having insulative guide posts positioned at opposite ends of the housing adjacent said slot, each post adapted to receive a side of the printed circuit card inserted into the slot, each post further including a lower section integrally formed with said housing and an upper section pivotally mounted on said lower section, and said upper section of each guide post being movable between a first operative position at which said connector is configured to receive and retain said printed circuit card and a second inoperative position at which said connector is unable to retain said printed circuit card during a portion of the process of mechanically and electrically mounting said connector to said printed circuit board.

Claim 4

A method of securing an edge card connector to the surface of a circuit board, comprising the steps of: providing a circuit board having a plurality of electrical traces connected to contact elements positioned on the surface of said circuit board; providing an edge card connector for receiving an edge card therein, said connector having an insulative housing including an opening for accommodating an edge of said edge card and a plurality of electrically conductive terminals positioned along said opening and having tail portions extending from said housing, said housing further including a pair of guide posts located at opposite ends of said opening, each guide post having means for accommodating a side of said edge card and being divided into an upper section and a lower section, said upper section of each guide post being pivotally mounted on said lower section; applying a solder compound to the surface of said contact elements; positioning said connector on a surface of said circuit board and aligning said tail portions with respective ones of said contact elements of said circuit board; pivoting said upper section to a first position adjacent said housing opening to reduce the distance between the circuit board and the portion of the connector furthest from said circuit board to reduce the overall height of said connector; processing said circuit board having said connector thereon through an automated surface mount soldering mechanism having an inlet opening of a certain predetermined height to solder said tails to their respective contact elements, said height of said inlet opening being greater than said overall height of said connector; and rotating said upper section of said guide post to a second position at which said guide post is configured to receive said edge card.

Claim 5

A method of securing an edge card connector to the surface of a circuit board, comprising the steps of: providing a circuit board having a plurality of electrical traces connected to contact elements positioned on the surface of said circuit board; providing an edge card connector for receiving an edge card therein, said connector having an insulative housing including an opening for accommodating an edge of said edge card and a plurality of electrically conductive terminals positioned along said opening and having tail portions extending from said housing, said housing further including a pair of guide posts located at opposite ends of said opening, each guide post having means for accommodating a side of said edge card and being divided into an upper section and a lower section, said upper section of each guide post being pivotally mounted on said lower section; applying a solder compound to the surface of said contact elements; positioning said connector on a surface of said circuit board and aligning said tail portions with respective ones of said contact elements of said circuit board; pivoting said upper section to a first position adjacent said housing opening to reduce the distance between the circuit board and the portion of the connector furthest from said circuit board to reduce the overall height of said connector; processing said circuit board having said connector thereon through an automated surface mount soldering mechanism having an inlet opening of a certain predetermined height to solder said tails to their respective contact elements, said height of said inlet opening being greater than said overall height of said connector; and rotating said upper section of said guide post to a second position at which said guide post is configured to receive said edge card.
