A multipolar connector set includes a first connector, a second connector including structure capable of being fitted to the first connector, a first substrate on which the first connector is mounted, a second substrate on which the second connector is mounted, a first ground conductor pattern formed on the first substrate, and a second ground conductor pattern formed on the second substrate. The first connector includes a first insulating member, first internal terminals held by the first insulating member and arranged in a first direction, and a first external terminal held by the first insulating member and connected to ground potential. The second substrate has a second conductor pattern non-formation region in which the second ground conductor pattern is not present at a position facing the first external terminal, when the first connector and the second connector are fitted to each other.

A coaxial connector set including a first connector to which a coaxial cable having a center conductor and an outer conductor is connected, and a second connector mounted on a circuit board having a ground coupling portion. The first connector has a first outer terminal, and the second connector has a second outer terminal. The first outer terminal has an outer conductor clamp portion, a first outer contact portion, and a tip surrounding portion positioned between the outer conductor clamp portion and the first outer contact portion and surrounding a tip portion of the center conductor. Shortcut coupling paths are formed between the tip surrounding portion and the second outer terminal or the ground coupling portion.

An electric connector set includes a first engaging terminal having spring engagement of a first projecting terminal of a first connector and a first recessed terminal of a second connector, a second engaging terminal having spring engagement of a second projecting terminal of the first connector and a second recessed terminal of the second connector, and disposed in a first direction, and a wall-shaped terminal disposed between the first and second engaging terminals in the first direction, extends along a second direction crossing the first direction and a fitting direction over a region including an outer shape of a projection region in the first direction where the first projecting and recessed terminals are spring-engaged, and has a similar height as the electric connector set. Locking mechanisms to retain connector engagement may be used and may be formed of a same member as the wall shaped terminal.

Electric connector set

An electrical connector set includes first and second connectors, in which the first connector has a first connection terminal, a first high-frequency connection terminal transmitting a high frequency signal, and a first external grounding member surrounding the first high-frequency connection terminal, the second connector has a second connection terminal, a second high-frequency connection terminal, and a second external grounding member surrounding the second high-frequency connection terminal. At a time of fitting, the second external grounding member is located on an inner side of the first external grounding member, the first and second connection terminals are located on an outer side of the first external grounding member, the second external grounding member is closed in a peripheral shape to surround the first and second high-frequency connection terminals, and first and second mounting parts are located on an inner side of the second external grounding member.

A surface mount connector in which an internal terminal does not extend to a location outside an external terminal is provided. A surface mount connector includes an external terminal that includes a tubular portion that extends in a first direction, an internal terminal that is separated from the external terminal inside the tubular portion when viewed in the first direction, and an insulator that is disposed between the internal terminal and the external terminal and that has a first main surface and a second main surface opposite the first main surface. The insulator inside the tubular portion has a through-hole that extends from the first main surface to the second main surface.

An L-shaped coaxial connector having a coaxial cable includes a coaxial cable including a central conductor portion and an external conductor portion disposed around the central conductor portion and a center conductor portion, an internal terminal connected to the central conductor portion, an external terminal connected to the external conductor portion, and an insulating member disposed between the internal and external terminals. The external terminal includes a cylindrical portion surrounding the first terminal portion and extending in a cylindrical shape in a direction intersecting an axial direction of the coaxial cable. The internal terminal includes a male type first terminal portion having a cylindrical shape and extending in the direction intersecting the axial direction, and a second terminal portion extending to connect from the first terminal portion to the central conductor portion. The insulating member includes a protruding portion protruding configured to insert into the first terminal portion.

A connector, a connector set, and a manufacturing method for a connector that suppresses intrusion or radiation of noise. A first connector includes a first ground conductor including a first outer conductor having a cylindrical shape and a virtual first center axis extending in a first direction, and a first contact section connected to the first outer conductor; a first center conductor in an area surrounded by the first outer conductor when viewed from the first direction; and a first lock member. When the first connector and a second connector are connected to each other, the first outer conductor is inserted in a second outer conductor, the first lock member pushes the second connector toward one side of the first direction, and the first contact section contact a second ground conductor to surround the periphery of the first outer conductor when viewed from the first direction.
