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.

Claims21

Dependent claims

A connector configured to be connected to a mating connector including a mating terminal and a mating shield, the connector comprising:

a housing;
a shield fixed to the housing;
and
a first terminal held by the housing, the first terminal being configured to be electrically connected to the mating terminal of the mating connector, wherein
the connector is configured to be connected to the mating connector by moving toward the mating connector in a predetermined direction relatively with respect to the mating connector,
the shield is extended in a circumferential direction surrounding the first terminal such that the shield surrounds the first terminal,
the shield includes a first shield portion and a second shield portion which face each other in a first direction perpendicular to the predetermined direction,
the first shield portion includes a first protrusion and a second protrusion which are arranged along the circumferential direction with a space between the first protrusion and the second protrusion, the first protrusion and the second protrusion being configured to contact the mating shield while the connector is connected to the mating connector,
the second shield portion includes a third protrusion and a fourth protrusion which are arranged along the circumferential direction with a space between the third protrusion and the fourth protrusion, the third protrusion and the fourth protrusion being configured to contact the mating shield while the connector is connected to the mating connector,
a maximum frequency of a transmission signal configured to flow through the first terminal is higher than or equal to 5 GHz, and
a creepage distance between the first protrusion and the second protrusion along the first shield portion and a creepage distance between the third protrusion and the fourth protrusion along the second shield portion are equal to or less than ¼ of a wavelength of the maximum frequency.
