Abstract:
A board-to board electrical connector assembly (10) is provided for effecting a connection between two circuit boards (52, 54). The assembly includes a first connector (12) having a dielectric housing (16) for mounting on a first circuit board. A plurality of first terminals (24) are mounted on the dielectric housing and each terminal includes a tail portion (24a) for connection to an appropriate circuit trace on the first circuit board and a convex contact portion (24c) defining a continuous arcuate contact surface (28). A second connector (14) has a dielectric housing (30) for mounting on a second circuit board. A plurality of second terminals (40) are mounted on the dielectric housing of the second connector and each second terminal includes a tail portion (44a) for connection to an appropriate circuit trace on the second circuit board, and a contact projection (50) for sliding over the continuous arcuate contact surface (28) of the convex contact portion (24c) of the first terminals (24) upon mating of the connectors.
Abstract:
Disclosed is an unlocking-proof PGA package socket which is so designed that upon the slide plate being put in its locking position for fastening a PGA package to the socket the longest vector of the circular cam member runs beyond the point of contact at which the cam member is put in contact with the slide plate, thereby allowing the kickback to push the cam member in the direction opposite to the direction in which the cam member turns toward unlocking position.
Abstract:
A card connector assembly for receiving a card member is provided with an eject device wherein the eject device is assembled directly onto the support frame of the card connector assembly to thereby reduce the number of components, the number of assembly steps and the resultant manufacturing costs of the connector assembly. The card connector assembly comprises a card guide portion (5a), a connector portion (9) to be connected to the card member, a support frame (3) continuous with both the card guide portion and the connector portion and an eject device (2). The eject device (2) comprises a slide member (22) slidably movable along the support frame (3), a movable lever (35) operating in accordance with movement of the slide member (22) for moving the card in a direction away from the card connector (7), and a cam mechanism (10) for defining the sliding range of the slide member (22). A part of the cam mechanism (10) is provided directly in the support frame (3).
Abstract:
A first connector is provided with a first terminal and a first housing that has a first mating guide portion, and a second connector is provided with a second terminal and a second housing that has a second mating guide portion. The first mating guide portion includes a recessed portion into which the second mating guide portion is inserted, and an end wall portion, wherein the inside faces thereof define the lengthwise-direction outsides of the first housing in the recessed portion.
Abstract:
A memory card connector includes an insulating housing defining a front receptacle area communicating with an interior cavity for receiving a memory card. A plurality of terminals are mounted on the housing and have contact portions at a rear of the cavity for engaging contacts on the memory card. A slider is movable mounted on the housing and is engageable with the memory card for movement therewith into and out of the cavity. A guide rail on the housing performs a dual function of (1) engaging the slider to guide the slider in its movement on the housing, and (2) preventing the memory card from being inserted into the cavity in an abnormal orientation.
Abstract:
A socket for a PGA package can maintain high reliability of connecting condition for a long period. The socket is constructed by mounting a reinforcement plate formed with a metal plate or the like at the position where the cam member contacts the slide plate so that the slide plate, which is formed of an insulative materials such as plastic or the like, will not be deformed upon exertion of a reaction force from a plurality of lead pins of a PGA package.
Abstract:
The present invention is directed to an electrical connector having at least two terminals that are short-circuited to each other by the use of a continuous portion. The continuous portion is formed during the manufacturing process of the terminals, thereby simplifying short-circuiting of two or more terminals together.
Abstract:
A board-to-board electrical connector assembly is provided for effecting a connection between two circuit boards. The assembly includes a first connector having a low profile dielectric housing including a mating face and a mounting face for mounting the connector on a first circuit board. A plurality of spaced mating posts project from the mating face of the housing. A second connector has a low profile dielectric housing including a mating face for mating with the mating face of the first connector and a mounting face for mounting on a second circuit board. The dielectric housing of the second connector includes a plurality of mating passages in the mating face thereof for receiving the mating posts of the first connector. The passages extend from the mating face all the way to and through the mounting face of the dielectric housing of the second connector.
