A fastening device for facilitating temporary fastening of an electronic component to a circuit board. The fastening device includes a base embedded in an electronic device and two elastic plates extending from the base. Each elastic plate includes a diagonal portion, which extend diagonally relative to the plane of the circuit board, and a leg, which extends continuously from the diagonal portion. When the legs are inserted through a connecting hole of the circuit board, the resilient force of the elastic plates presses the diagonal portions against the wall of the connecting hole.

Device for temporarily fastening electronic component to circuit board

A connector includes a connector body and bases formed on the lower surface of the connector body. When the connector is fixed to a printed board, a part of each base or the lower surface of the connector body contacts the surface of the printed board in accordance with the thickness of the board. Therefore, the connector can be fixed to any one of printed boards having different thicknesses with common fixing pins.

Connector and fixing structure of connector and board

A connector housing ( ) of a connector ( ) is constituted by a lower housing ( ), which is mounted on a printed circuit board ( ), and an upper housing ( ) connected to the lower housing ( ) in such a manner as to be able to perform shifting movement with respect the housing ( ). Further, terminals ( ) are provided in such a way as to penetrate through a partitioning wall portion ( ) of the upper housing ( ) and through a connecting block portion ( ) of the lower housing ( ). At that time, tapered holes ( ) are provided in the connecting block portion ( ). The terminals ( ) are maintained in a state in which a bending deformation thereof caused by the shifting movement of the upper housing ( ) is allowed. Consequently, when the connector ( ) is connected to the mating connector ( ), the connectors ( ) can be connected to each other by performing the shifting movement of the upper housing ( ) thereby to concurrently absorb the positional displacement therebetween. Moreover, occurrences of problems, such as breakage and bend of the terminals ( ) at that time, are prevented.

Printed circuit board connector

A plug-in connecting structure where a first unit, on an outer surface of which a first connector housing is installed, and a second unit, on an outer surface of which a second connector housing is installed, are connected electrically with each other by connecting the connector housings with each other, simultaneously with the mechanical connection of the units with a certain support being as a guide. When advancing toward a connecting portion of the second connector housing, a connecting portion of the first unit automatically aligns its center axis with a center axis of the connecting portion of the second connector housing, with being guided by a tapered surface. The first and second connector housings are never forcibly connected with each center axis thereof remaining offset from each other.
