Abstract:
A shield structure having a plurality of hollow columnar base members arranged with intervals therebetween along the periphery of a section to be shielded on a surface of a circuit board, and a shield cover with a peripheral wall having insertion pieces arranged along the edge thereof at positions corresponding to the positions where the base members are arranged. Each base member has a cut in at least a top surface thereof. The cut forms an elastically deformable tongue portion having a free end at a position where the corresponding insertion piece of the shield cover is inserted. The tongue portion is elastically deformed toward the inner space of the base member by an insertion force applied when the corresponding insertion piece of the shield cover is inserted into the cut at the free end. The tongue portion functions as an elastic holding portion that retains and fixes the shield cover on the base member by applying an elastic resilient force such that the free end thereof presses against the insertion piece of the shield cover.
Abstract:
In a card device having a circuit substrate housed in a card casing and an antenna disposed rotatably on the exterior of the card casing, an antenna rotary shaft composed of a conductive material is provided at the base end of the antenna. The antenna rotary shaft extends from the exterior to the interior of the card casing along a substrate surface of the circuit substrate via a through hole of the card casing in such a manner that the antenna rotary shaft is supported rotatably by the card casing while being elevated from the circuit substrate. A section of the circuit substrate that is opposed to the antenna rotary shaft has a feeding terminal fixed thereto. The feeding terminal has a pair of antenna-rotary-shaft elastically-pressing portions that sandwich and electrically contact the antenna rotary shaft from opposite sides with elastic forces in a surface-contact fashion.
Abstract:
A compact flash (CF) card includes, in a front portion, a space-entering portion that enters the space between a top plate and a bottom plate provided on the upper and lower sides of connecting terminal pins arranged at the front end of a CF-card storage section of a PC card adapter. The connecting terminal pins are protected by the top plate and the bottom plate. The CF card storage section of the PC card adapter has an opening in the upper surface on the card insertion side. An upper portion of the CF card that is exposed from the opening includes a tall portion having a greater height than the space-entering portion. The CF card can be loaded in a PC card adapter having a simple structure, and taller electronic components can be mounted in the tall portion, than in a CF card which is equal in height to the space-entering portion over the entire range from the front end to the rear end.
Abstract:
A PC card is mounted with the connector on the card side at the connector mounting receptacle thereof, and the ground electrode is provided at an upper side thereof. Further, the adhesive film on the upper panel side is provided at the interior opposite to the connector on the card side of the upper panel, and the adhesive film on the connector side is provided on the upper surface of the rectangular body of the connector on the card side. The connector on the card side is mounted to the connector mounting receptacle, and upon that the ground electrode and the upper panel are provided at the upper side, and the lower panel is provided at the lower side. By heat pressing with a hot press, the adhesive film on the upper panel side and the adhesive film on the connector side fix the rectangular body of the connector on the card side and the plane part of the ground electrode in a state enhancing intimate contact thereof.
Abstract:
A ground electrode is disposed between a card-side connector and an upper panel, movably forward or backward in the card insertion direction, the ground electrode including protuberances projecting through the protuberance receiving holes of the upper panel. The ground electrode is energized to move forward in the card insertion direction by means of a torsion spring such that, when the PC card is inserted into a 16-bit card slot corresponding to a predetermined high driving voltage, the protuberances in the protuberance receiving holes are moved backward in the card insertion direction against the spring force of the torsion spring.
Abstract:
A card device includes a card casing accommodating a circuit board. The card device is capable of being inserted into and pulled out from a card slot in an apparatus in which the card device is to be mounted. An anti-slipping member is anchored and exposed at a rear-end wall portion of a peripheral wall of the card casing for being held at least when the card device is inserted or pulled out. The rear-end wall portion is positioned at a rear end of the card device opposite to the end of the card device that is inserted into the card slot.
Abstract:
A card device includes a card case, a circuit board disposed in the card case, and an antenna rotatably disposed on the outside of the card case. An antenna rotating shaft is disposed on the base end of the antenna and inserted from the outside into the inside of the card case through a through-hole of the card case such that the antenna rotating shaft extends along the surface of the circuit board and is supported within the card case with the inner part of the antenna rotating shaft being spaced apart from the circuit board and the antenna rotating shaft being freely rotatable. A feed terminal having elasticity that urges the feed terminal against the antenna rotating shaft is disposed between the antenna rotating shaft and a part of the circuit board facing the antenna rotating shaft. The feed terminal is fixed to an antenna connection part of a circuit formed on the circuit board facing the antenna rotating shaft. The feed terminal is urged by its elasticity into contact with the antenna rotating shaft.
Abstract:
A connector device includes lock male screws which can be screwed to lock female screws of an apparatus on which a locking operation is carried out, nuts for freely inserting the lock male screws and for allowing movement of the lock male screws between a screwed position and a non-screwed position, and lock female screws which, with the lock male screws being retracted to the non-screwed positions, are screwed to the nuts, and which are screwed to lock male screws of the apparatus on which a locking operation is carried out. By switching the states of the lock female screws between a mounting state and a non-mounting state with respect to the nuts, the lock screws of the connector device can be used even if the forms of the lock screws change with respect to the connector device. This causes the female connector and the male connector to be firmly secured together, thereby making the connector device more versatile.
Abstract:
A PC card includes a circuit having a first function, a circuit having a second function, a selector for selecting either the first or second function, and a slot-type identification mechanism for identifying the type of PC card slot. The selector selects either the first or second function according to an identification signal received from the slot-type identification mechanism. Upon insertion into a PC card slot, the PC card self-identifies an operation mode.
Abstract:
A PC card has a connector attaching port into which a card-side connector is fixed. Each spring protuberance of a ground electrode having a fixing frame fixed to a connecting beam of a frame extends on the upper face of the card-side connector. The projection portion of the spring protuberance projects upwardly through a protuberance accommodating hole provided in a plate of the frame. When the PC card is inserted into a 16-bit card slot, each spring protuberance is distorted downwardly through an insertion hole on the card slot side. Thus, the PC card can be attached to both the 16-bit and 32-bit card slots.
