Kazushige Asakawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: An electrical connector includes a dielectric housing having an opening for receiving a mating connector. A plurality of terminals are mounted on the housing and have contact portions exposed at the opening for engaging appropriate contacts of the mating connector. A shutter plate is mounted on the housing for movement from a protective position at the opening for covering and protecting the contact portions of the terminals, to a retracted position upon mating of the mating connector to allow the contact portions of the terminals to engage the contacts of the mating connector. At least one flexible locating spring is disposed between the shutter plate and the housing to allow the shutter plate to yield relative to the housing during movement between its positions and prevent binding of the shutter plate upon movement relative to the housing.
Abstract: An electrical connector includes a dielectric housing, with a plurality of conductive terminals mounted in the housing. At least one of the terminals is a ground terminal. A metal shield is mounted on the housing. An intermediate conductive terminal is mounted on the housing and includes one end engaging the metal shield and an opposite end engaging the ground terminal.
Abstract: The present invention improves the durability of a card connector by providing a card-holding structure which does not have resilient parts.
Ribs (30) and grooves (32) are formed at corresponding positions in opposite inside surfaces (6a, 6b) of a rear end portion of a card-receiving slot (6) of a housing (2) to accommodate a card (C) inside housing (2). An upper surface of the inserted card extends into the grooves (32) by the ribs (30), so that the card is held between the ribs (30) and grooves (32).
Abstract: A card connector includes a detecting unit indicating the full insertion of a card into a card-receiving slot that provides no pressure on the card in the direction of its ejection, thereby providing for better reliability of electrical connections between the connector and the card. Card (C) is inserted in card-receiving slot (4) of housing (2) of card connector (1). When the card (C) is fully inserted in the card-receiving slot, one side of the card presses down V-shaped contact section (52a) of sensing member (52) breaking its electrical contact with sensing member (54), thus confirming the full insertion of the card into the card-receiving slot. The V-shaped contact section (52a) exerts pressure against the card (C) in a perpendicular direction.
Abstract: Connector housings (11, 12) to be mounted on a printed circuit board (100) have a plurality of rows of contacts (13, 14) extending from wall surfaces of the housing (11, 12). These contacts (13, 14) are soldered to conductive pads (23) of a flexible circuit (20). The flexible circuit (20), bent in a generally U-shaped, about an insertion portion (31) of a metallic guide portion (30) which is to be inserted between rows of contacts (50) of a mating connector (40) for interconnection therebetween. The guide member (30) preferably engages a ground conductor (176) on the reverse surface of the flexible substrate and includes extending portions (142) to groundingly engage conductive member (43, 124) positioned at both ends of the housing. In an alternate embodiment strengthening plates may be adhered to the flexible circuit between the opposed arrays of conductive pads and ground contact pads.
Abstract: Flat cable connector 10 having numerous flat-plate-form contacts 30 in an insulating housing 20. Each contact 30 has a first arm 33 and a second arm 34coextending forwardly from a base part 31 so that the two arms are substantially parallel to each other. A contact point 35 is formed proximate the free end of the first arm 33, and an engaging projection is formed on the free end of the second arm 34 that protrudes beyond the front surface 23 of the insulating housing 20 The end portion of the flat cable 50 inserted between the arms 33 and 34is pressed by pushing the tongue part 42 of the slider 40inward so that a contact pressure is applied between the contact points 35 and the conductors of the flat cable 50Furthermore, the slider 40 is fastened to the insulating housing 20 via the contacts 30 by the latching engagement of an engaging recess 47 with the engaging projections 36.
Abstract: The object of the present invention is to reduce housing size and make it possible to provide connections between connecting members of a flat cable and electrical terminals at a high density in a limited housing space, while minimizing the number of flat cables mounted in the housing and keeping flat cable manufacturing costs down. The flat cable connector 10 comprises a housing 20 which accommodates and holds a plurality of electrical terminals 30, a slider member 40 which is supported on the housing 20 so that the slider member 40 can slide back and forth, and a flat cable 50 which is positioned in the housing 20 and connected with the terminals 30.
Abstract: A connector is disclosed which draws static charges to ground. The connector comprises a male plug having a generally non-yielding terminal attached to a projection extending from its mating surface and a female receptacle having at least one terminal mounting cavity in a mating surface and a flexible female terminal in the cavity. The female receptacle has a metal cover on its outer surface which is connected to ground. The male terminal and projection is dimensioned so as to permit insertion through the aperture in the cover and into a slot in the female housing. The flexible female terminal remains contained within the slot of the female housing and below the cover prior to making contact with the male terminal.
Abstract: An electrical contact is disclosed for use in an electrical connector to be surface mounted to a printed circuit board. The contact includes an inverted U-shaped portion defining a pair of depending legs. One of the legs has a foot portion for electrical connection to an appropriate circuit trace on the printed circuit board. A terminal portion is turned upwardly from a distal end of the other leg for termination with an appropriate mating terminal. The contact is in the form of a one-piece metal component. In the preferred embodiment, the terminal portion of the contact is in the form of a terminal pin, with the pin and the legs of the inverted U-shaped portion of the contact all being generally parallel.
