Abstract: A connector includes a housing, an outer shield including a tubular portion, and a terminal surrounded by the tubular portion of the outer shield. The connector is connected to a mating connector by moving toward the mating connector in a predetermined direction relatively with respect to the mating connector. A first end of the tubular portion of the outer shield is located in the predetermined direction in the tubular portion. The tubular portion of the outer shield has an inner circumferential surface facing a hollow space, an outer circumferential surface opposite to the inner circumferential surface, and a distal end surface provided at the first end. At least one of the distal end surface, the outer circumferential surface, and the inner circumferential surface is seamless over an entire circumference of the tubular portion surrounding the hollow space along a circumferential direction of the tubular portion.

Abstract: In a connector, each of housings of a socket and a header serving as connector parts includes: a terminal holder extending in a first direction and includes a terminal section of the associated connector part; and a side wall connector extending in a second direction intersecting the first direction, and connected to one end of the terminal holder of the associated connector part in the first direction. The shield member includes a first portion on the side wall connector, and a second portion aligned with the terminal holder of the connector part in the second direction. The socket and the header are inserted into each other in a third direction intersecting the first and second directions. The second portion of at least one of the shield members includes a shield bent portion with a curved portion curving toward the other connector part to be inserted.

Abstract: A connector includes an outer shield, a terminal surrounded by the outer shield, a housing fixed to the outer shield and holding the terminal; and an inner shield surrounded by the outer shield. The outer shield, the inner shield, and two virtual paths that connect the two tip regions of the inner shield to the outer shield by shortest distances, respectively, constitute plural electrically-closed loops surrounding the terminal. The electrically-closed loops include one or more particular electrically-closed loops. Each of the one or more particular electrically-closed loops does not surround any electrically-closed loop among the plurality of electrically-closed loops other than the each of the one or more particular electrically-closed loops. A longest loop length of the one or more loop lengths of the one or more particular electrically-closed loops is shorter than a wavelength of a maximum frequency of a transmission signal flowing through the terminal. This connector reduces resonance of a transmission signal.

Abstract: A connector includes a housing, an outer shield fixed to the housing and including a tubular portion, and a terminal held by the housing and surrounded by the tubular portion of the outer shield. The tubular portion has a first end and a second end opposite to each other. The first end and the second end of the tubular portion open. The tubular portion surrounds a hollow space. The connector is configured to be connected to a mating connector by moving toward the mating connector in a predetermined direction relatively with respect to the mating connector. The first end of the tubular portion of the outer shield is located in the predetermined direction in the tubular portion. The tubular portion of the outer shield has an inner circumferential surface facing the hollow space, an outer circumferential surface opposite to the inner circumferential surface, and a distal end surface provided at the first end. At least one of the distal end surface, the outer circumferential surface, and the inner circumferential surface is seamless over an entire circumference of the tubular portion surrounding the hollow space along a circumferential direction of the tubular portion.

Abstract: A connector includes plural terminals, a housing holding the terminals, and an inner shield. The connector is configured to be connected to a mating connector by moving toward the mating connector in a first direction relatively with respect to the mating connector. The terminals include two terminals arranged on both sides of the inner shield in a second direction perpendicular to the first direction. The inner shield includes a base extending in a third direction perpendicular to the first direction and the second direction, and an extension protruding from the base. The housing includes a shield holder holding the extension. This connector reduces noise propagation between the terminals.

Abstract: A video data transmitter apparatus generates and transmits a multi-value amplitude modulation signal by performing a multi-value amplitude modulation of a plurality of N bits per one symbol according to video data of a video signal or a color signal constituting the video signal, or a brightness signal and a color-difference signal. A data separator portion separates the video data into first to N-th pixel data, a difference calculator portion calculates (N−1) pieces of predetermined difference information based on the separated first to N-th pixel data, and a multi-value amplitude modulator portion performs a multi-value modulation so that predetermined N-bit data corresponds to a multi-value signal level closest to an intermediate level having an intermediate value between a maximum level and a minimum level of the multi-value signal level of the multi-value amplitude modulation signal.
