ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to electrical connectors, especially to electrical connectors comprising metal fixtures to receive screws for attaching the connectors to a panel or to a circuit board.
BACKGROUND OF THE INVENTION
An example of an electrical connector of the type of an electrical connector relating to the present invention is disclosed in Japanese Patent Publication 58-95578 wherein the connector disclosed therein has metal fixtures located at both ends of the connector, the purpose of which is to attach the connector to a panel or circuit board. The metal fixtures receive screws, thus mounting the housing to the panel or circuit board.
Recent trends in the reduction in size of electrical connectors require reducing the connector height as well. Therefore, the portion of the housing that contains the metal fixtures must be made very thin. However, since the housing is made too thin, there is a danger that the housing may break due to the force of the tightened screws or due to their rotation.
Therefore, the purpose of the present invention is to provide an electrical connector wherein the stress applied to the housing during the attachment of the connector by means of threaded devices is sufficiently low, thus making it possible to make the electrical connector comparatively low in height.
SUMMARY OF THE INVENTION
The electrical connector of the present invention has a metal shield affixed to an outer surface of a dielectric housing, and metal fixtures comprising a threaded section for attachment of the connector to a circuit board and for the connection of the metal shield to a grounding bus of the circuit board, the metal fixtures are engaged with the metal shield so that the metal fixtures cannot rotate relative to the metal shield, and that the metal fixtures assure that one side of the housing engages with the metal shield and the other side of the housing engages with the circuit board when the connector is mounted thereon.
The metal fixtures include a guiding device intended for guiding the mating connector during the joining of the connectors.
The cross section of a portion of the metal fixtures is asymmetrical in the rotation direction and that the openings in the shield into which the metal fixtures are inserted have a configuration that complements the cross section.
The openings have spring-loaded retaining members fitting into grooves in the metal fixtures.
The housing is provided with through holes accommodating threaded retaining devices of the metal fixtures which have grooves into which the spring-loaded members can be accommodated.
