Abstract: The present invention provides a card connector assembly that is used for the connection with two cards having mutually different transmission speeds and that can maintain transmission characteristics while minimizing the amount of an expensive FPC used. The card connector assembly comprises stacked first and second card connectors for 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 path for the first card connector to which a card with a relatively high transmission speed is to be connected is constructed from an FPC to which the first card connector is connected. The transmission path for the second card connector to which a card with a relatively low transmission speed is to be connected comprises terminal parts that extend from the second card connector, and a rigid board to which the terminal parts are connected.

Abstract: A board mounted electrical connector includes signal contacts, grounding contacts, and an insulative housing for holding the signal contacts and the grounding contacts. At least one pair of signal contacts and a grounding contact corresponding to the pair of signal contacts are arranged in two rows at an engagement portion of the insulative hosing. Leg portions of the signal contacts and the grounding contacts, which are to be mounted onto a circuit board, are arranged in three rows at positions closest to an engagement surface of the insulative housing to positions furthest from the engagement surface. Leg portions of the grounding contacts are provided in the first row closest to the engagement surface.

Abstract: 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.

Abstract: An electrical connector assembly in which conductor pads on a board are used as contacts is described. Signal conductor pads transmitting positive and negative differential signals, are disposed on one side of the board. A ground pad is disposed on the opposite side of the board so that it is positioned at an intermediate point between the positive and negative signal conductor pads, thus forming one set of pads. The signal conductor pads of another adjacent set, are disposed on the same side as the signal pad of the previous set such that their negative differential signals an adjacent. The pad of a third set (not shown in the figures) which is adjacent to the positive signal pad of the second set is a pad that transmits the same positive differential signal. As a result, signal crosstalk can be prevented.

Abstract: The present invention aims to provide an electrical cable assembly which is inexpensive and allows a user to make a proper connection between devices. Electrical connectors which are fixed on both ends of the cable are provided with a visual indicator which enables a user to make a proper connection with a tuner or PDP (Plasma Display Panel) even with the interchangeable mating surfaces of the electrical connectors.

Abstract: The male connector 1 has a metal shielding shell 4 that accommodates a housing 2 and a synthetic resin enclosure 8 that covers approximately the rear half of this shielding shell 4. Fastening parts 40 and protruding parts 42 are formed by stamping in the upper-side shell half-body 4a. A metal latching arm 44 which is formed with the approximate shape of a shallow inverted V, and which has an engaging part 54, is disposed between these fastening parts 40 and protruding parts 42. The latching arm 44 can be pressed by means of a finger-catch part 68. This configuration obtains the desired shielding performance while maintaining a compact size in a shielded electrical connector assembly.

Abstract: An improved high speed connector is provided in which conductive pads (34) are alternately disposed on both sides of a board (10). The conductive pad (34a) transmits a + differential signal, and the conductive pad (34b) transmits a − differential signal. These conductive pads are disposed on the same surface (10a). The pad (34c) used for grounding is disposed on the opposite surface (10b) so that this pad (34c) is positioned between the conductive pads (34a) and (34b), thus forming one set of pads. In the case of the conductive pads (34d), (34e) and (34f) of another adjacent set, the pad (34d) which transmits a − differential signal is disposed on the same side as the pad (34b) of the previous set which transmits the same − differential signal. The pad (34f) used for grounding is disposed on the opposite side from the pads (34d) and (34e).

Abstract: An electrical connector assembly in which conductor pads on a board are used as contact is described. The conductor pads (34) are alternately disposed on both sides of a board (10). The conductor pad (34a) transmits a positive differential signal, and the conductor pad (34b) transmits a negative differential signal; these conductor pads are disposed on the same side (10a) of the board (10). The ground pad (34c) is disposed on the opposite side (10b) of the board (10) so that this ground pad (34c) is positioned at an intermediate point between the conductor pads (34a) and (34b), thus forming one set of pads. In regard to the conductor pads (34d), (34e) and (34f) of another adjacent set, the pad (34d) which transmits a positive differential signal is disposed on the side of the pad (34b) of the previous set, which transmits the same negative differential signal. The ground pad (34f) of this set is disposed on the opposite side of the board (10) from the pads (34d) and (34e).
