Abstract
A socket (20) for interconnecting an electronic module (2) to circuit board (14) includes an insulative housing (30) having a plurality of terminals (22) applying a moment to the module (2). A latch (100, 200, 300, 400, 500, 600) is positioned within a pocket (40) at each end of the insulative housing (30). The latch has two legs joined by a bight, the two legs being flexible as the module (2) is rotated into a slot (34) in the insulative housing (30) The latch includes an integral securing projection (152, 252, 352, 453, 552, 652) which cooperates with an opening (12) to maintain the module (2) in position relative to the housing (30).
Claims28
A socket for interconnecting an electronic module to a circuit board, the socket comprising:
- an insulative housing, having a module receiving recess which extends from proximate one end of the housing to proximate the opposite end of the housing;
- a plurality of terminals positioned within the insulative housing, the terminals being configured to establish electrical contact with the module upon rotation of the module from a first position to a second position, the terminals applying a moment to the module when the module is in the second position;
- a separate resilient latching means, located proximate one end of the housing, for holding the module in the second position and resisting the moment applied to the module by the terminals;
- the resilient latching means has an integral wedge portion and an integral securing tab, the wedge portion deflects as the electronic module is rotated between the first position and the second position, the securing tab extends in a direction which is essentially perpendicular to the longitudinal axis of the module receiving recess and is positioned in an opening in the electronic module when the electronic module is provided in the second position to prevent the electronic module from being improperly removed from the socket when the electronic module is in the second position.
An electrical connector for connecting a first substrate to a second substrate, the second substrate being rotatable relative to the first substrate between a first and an second position, the electrical connector having a housing with a recess provided therein, the recess extends from proximate a first end of the housing to proximate a second end of the housing, and is dimensioned to receive the second substrate therein, contact terminals are positioned adjacent to the recess, and are configured to make an electrical connection with the second substrate when the second substrate is in the second position in the recess, the electrical connector comprising:
- a latch receiving portion positioned proximate to the first end of the housing and proximate the recess of the housing;
- a separate resilient latch positioned to cooperate with the latch receiving portion, the latch has a mounting portion which is positioned to cooperate with the latch receiving portion, a latching portion which extends from the mounting portion toward the recess, and a securing portion which extends from the mounting portion toward the recess;
- the securing portion will cooperate with an opening in the second substrate;
- whereby as the second substrate is rotated from the first position to the second position, the latching portion of the latch cooperates with the second substrate to prevent the second substrate from being rotated back toward the first position, and the securing portion is positioned in the opening of the second substrate to prevent the second substrate from being withdrawn from the recess.
An electrical connector for connecting a first printed circuit board to a second printed circuit board, the electrical connector comprising:
- a housing of dielectric material, mountable on the first printed circuit board, the housing including a base having a recess for receiving the second printed circuit board, the second printed circuit board being rotated relative to the first printed circuit board from a first position to a second position, the housing having a housing projection which extends from the housing proximate an end thereof;
- a plurality of contacts positioned in the base adjacent the recess for establishing an electrical interconnection to the second printed circuit board;
- a separable metal latch positioned proximate the recess, the latch having a flexible inner arm and an outer mounting arm;
- the metal latch being secured in the housing by engagement of the mounting arm with the housing, the metal latch having a latch projection and a securing projection, the latch projection cooperates with the second printed circuit board to maintain the second printed circuit board in the second position;
- the securing projection is positioned transverse to the longitudinal axis of the recess, and is spaced from a first section of the metal latch by a distance which is greater than the width of the housing projection to allow the securing projection to move relative to the housing projection as the second printed circuit board is rotated between the first and the second positions, the securing projection is configured to be received in an opening of the second printed circuit board when the second printed circuit board is rotated to the second position, thereby preventing the improper removal of the second printed circuit board from the housing.
A circuit board latching device for a connector comprising:
- a mounting section which cooperates with an insulating housing of the connector to maintain the circuit board latching device in position relative to the connector;
- a resilient circuit board latching section to latch a circuit board in position relative to the connector;
- a releasing section, integral with the resilient circuit board latching section, for externally releasing the latching of the circuit board by the resilient circuit board latching section;
- a securing section, to secure the circuit board in the connector when the circuit board is latched by the resilient circuit board latching section, the securing section has a first movable portion and a second securing portion which is attached to the first movable portion by a bight portion;
- whereby the mounting, latching, releasing, and securing sections are integrally made of a metal plate member.
