Abstract
A mechanism structure for decoupling prong and socket type electrical connections, particularly for circuit board cards and their connections to receptacle-connectors in chassis-like housings. In one embodiment, the decoupling structure comprises a plate, a rotatable rod supported by the plate, an actuating lever attached to one end of the rod, and a cam attached along the rod. In application, the lever is pushed or pulled causing the cam to apply a force separating the circuit board from the receptacle connection so as to reduce or avoid torsional forces when disconnecting the board from the receptacle.
Claims23
A mechanical assembly comprising;
- (a) a circuit board card having at least one circuit board with at least one connector and a shoulder portion about the connector, the card adapted to be mateable at an interface to at least one connector of a receptacle;
- (b) a separate plate neither mechanically attached to nor molded from the card and the receptacle, the plate positioned about the interface of the card connector and the receptacle connector, having an upper surface portion adapted to abut against the receptacle and a lower surface to abut against the shoulder portion of the card;
- (c) a rod, having first and second ends, rotatably supported by the upper surface of the plate;
- (d) a rotatable arm attached to the rod between the first and second ends;
- and
- (e) a lever handle connected to one end of the rod for providing a rotational force to the arm to urge the board and the receptacle apart.
A method for mechanically disengaging a prong and socket electrical connection comprising the steps of:
- positioning a rotatable arm at an interface between the prong and the socket;
- and
- rotating the arm so as to engage the prong and the socket to force the prong and the socket apart, and
- supporting the rotatable arm by two vertical supports attached to a separate plate, wherein the plate is neither mechanically attached to nor molded from the prong and the socket.
A method for mechanically disengaging mated connectors of a circuit board card and a receptacle comprising the steps of:
- providing a lever attached to one end of a rod and at least one rotatable arm attached between the lever and the other end of the rod;
- supporting the rod by a plate which is neither mechanically attached to nor molded from the connectors, said plate being formed with at least one opening for allowing the connectors to be mated therethrough, and a support extending from one side of the plate and adjacent the opening for rotatably supporting the rod;
- positioning the plate between the receptacle and the card so that their connectors can mate through the opening;
- and
- actuating the lever to cause the arm to rotate and separate the card and the receptacle.
A tool for mechanically decoupling an electrical prong from an electrical socket comprising:
- (a) an arm rotatably positioned between the prong and the socket in a manner so that the arm is rotatable to engage the prong and the socket;
- (b) a lever to effect rotation of the arm to engage the prong and the socket in order to apply a force to separate the prong and the socket apart;
- (c) at least one rotatable rod connected to both the arm and the lever;
- and
- (d) a plate for rotatably supporting the rod, wherein the plate is neither mechanically attached to nor molded from the prong and the socket.
A tool for mechanically decoupling an electrical prong connector from an electrical socket connector comprising
- a rotatable arm for positioning about an interface connection of one connector and an other connector;
- a base for supporting the arm positioned between the arm and one connector, wherein rotating the arm causes the arm to engage both the base and the other connector causing a vertical separation of the connectors from one another;
- and
- wherein the base includes a plate for rotatably supporting the rotatable arm, wherein the plate is neither mechanically attached to nor molded from the connectors.
An electrical connector arrangement including a cam mechanism comprising:
- a first electrical connector adapted to abut against one side of a first plate and extend through the first plate so that contacts of the connector are accessible from the other side of the first plate, wherein the first late is neither mechanically attached to nor molded from the first electrical connector;
- a second electrical connector secured to a second plate and adapted to mate with the first connector;
- and
- cam means positioned between the first and the second connectors having a connect position for enabling the first and second connectors to mate, and is rotatable from the connect position in a direction to urge the first and the second plates apart for disconnecting the connectors.
