A connector&#x22c5;substrate assembly can be disposed at a position where a tip portion of the connector is inserted into a connector hole simply and at a low cost without using an additional small substrate, an additional relay cable, and the like; an electronic device; and a method for assembling the same are provided. A connector is supported so as to be slidable with respect to a substrate, from a preparation position to a mounting position, and the tip of the connector projects outwardly from a right side of an end portion of the substrate at least at the mounting position. A chassis has a connector hole in the side surface. The connector does not interfere with a frame portion of the connector hole at the preparation position and the substrate can be properly attached to the chassis. The tip of the connector enters the connector hole at the mounting position. By slidably supporting the connector as described above, a small substrate, a relay cable, and the like become unnecessary, so that a reduction in the number of parts and simplification of an assembling process are achieved.

The present invention provides an inexpensive card connector assembly which is used for the connection with two cards having mutually different transmission speeds, which can maintain transmission characteristics, and which is therefore suitable for high-speed transmission. The card connector assembly comprises first and second card connectors that are stacked for the connection with two cards having mutually different transmission speeds, and transmission paths for connecting the first and second card connectors to a circuit board. The transmission paths comprise a plurality of first and second terminal parts that respectively extend from the first and second card connectors, and a rigid board to which the first and second terminal parts are connected. The first terminal parts which extend from the first card connector that is to be connected to a card with a relatively high transmission speed are such that a large portion of each adjacent first terminal part from the first card connector to the rigid board extends parallel in a single row.

A compact ZIF type socket is provided having the durability to withstand numerous movements of the slider. The ZIF type IC socket consists of a base housing assembly that accommodates numerous contacts, and a cover housing assembly that can slide over the base housing assembly . The cover housing assembly is caused to move in relative terms by inserting a plate-form tool into tool insertion holes and respectively formed in a metal supporting plate on the side of the base housing assembly and a metal supporting plate on the side of the cover housing assembly , and rotating this tool . The action points of the tool insertion holes and contacted by the tool are formed as circular-arc-form projections and . Accordingly, the force of the tool can be transmitted to the base housing assembly and cover housing assembly without causing indentation or damage, etc., of the tool insertion holes and , so that a highly durable ZIF type socket can be obtained.

A latching device (10) for a card edge connector (30) and auxiliary board (60) having a first arm (12) and a second arm (14), wherein the second arm includes a latching unit (20) and a latching release unit (26), when the latching device (10) is inserted into a receptacle compartment (46) in the connector (30), the first arm (12) is biased toward the second arm for fixing the latching device (10) in the receptacle compartment. The latching unit (20) includes round shoulders (22, 24) which are provided to fit into round recesses (62) of an auxiliary board (60). A directed pressure (A, B, C) placed on the release unit (26) causes the latching unit (20) to rotate away from an area in card edge connector (30) where an auxiliary board is disposed.

The purpose of this invention is to offer an edge connector which requires less space for insertion of a card and has a reduced stress in the housing due to dissipation of mechanical stress. Accordingly, the invention comprises a C-shaped connector 1 having a housing that has a reception groove 8 and guiding grooves 10, 10' for a memory card 100. In the upper walls forming the guiding grooves 10, 10' protrusions 12, 14 are formed. These protrusions match indentations 108, 110 in the memory card. The memory card 100 can be inserted into the guiding grooves 10, 10; only when the protrusions 12, 14 and indentations 108, 110 are properly aligned. After that the memory card is moved along the grooves 10, 10' toward the contacts 70, 70' arranged in the main body 4 of the housing. Contacting arms 78, 78' of adjacent contacts 70, 70' make connection alternately with the conducting pads 106 on the upper surface 111 and lower surface 112 of the memory card 100, thus preventing the concentration of mechanical stress in the housing 2 retaining contacts 70, 70' therein and to the solder connections of the contacts to a circuit board 18.

An improved board-to-board electrical connector includes opposite guide posts whose height can be reduced before the connector is placed into an automated soldering apparatus for soldering the connector terminals to selected conductors of a printed circuit board. Each guide post includes an upper and a lower section and the height adjustment of the guide posts is effected by pivotally mounting the upper sections of the guide posts such that they can be rotated into a vertical or horizontal position.

Disclosed is a surface-mounted component's contact having an inverted 'T'-shaped soldering portion. The contact is to be mounted to the surface of a printed circuit board, and is to be electrically connected to a conductor on the printed circuit board by soldering its soldering portion to the conductor. The soldering portion comprises a flat foot and a leg, which is integrally connected to and rising from the midportion of said foot. The relatively large foot has an effect of causing substantial reduction of the load per unit of solder upon application of an undesired force to the terminal, and of increasing the resistivity of the solder against removal from the conductor of the printed circuit board.
