Abstract: A cantilever spring is positioned in a slit in a shell, and has a free end and a fixed end fixed to the shell. The cantilever spring extends in a height direction of the shell. The fixed end of the cantilever spring is positioned near a part that is attachable to a board, and the free end of the cantilever spring is apart from that part.

Abstract: In a connector assembly in which a first connector and a second connector are fitted to each other, a first shell, which has a rectangular frame-like shape and serves as an outer shell of the first connector, includes curved portions on upper ends of respective sides of the rectangle, and a second shell, which has a rectangular frame-like shape and serves as an outer shell of the second connector, includes convex portions, which are elongated along respective sides to be slender, on outer surfaces on the sides of the rectangle. The curved portions and the convex portions are positioned so that the curved portions and the convex portions are partially overlapped with each other. The convex portions are in contact with the first shell through the entire lengths, and the curved portions are in contact with the second shell through the entire lengths.

Abstract: In a connector, movement of a contact is appropriately restricted in detaching a counter connector from the connector. The connector fittable with the counter connector in a first direction includes the contact and a housing. The contact includes: a press-fitted portion press-fitted into the housing in a second direction intersecting the first direction; an extension portion that extends from the press-fitted portion in a third direction intersecting the first and the second directions; and a contact portion that extends from the extension portion and contacts the counter contact. The housing includes a protrusion portion that protrudes from a rising portion in the third direction. In a state where the press-fitted portion is press-fitted in the housing, a surface of a distal end portion in the third direction of the extension portion contacts the protrusion portion, which surface faces a side where the counter connector is situated.

Abstract: Each of a first connector and a second connector of a connector assembly includes at least two high frequency signal terminals. When viewed from a first direction, each periphery of the high frequency signal terminals is surrounded by an outer shell and an inner shell. The outer shell has a substantially quadrilateral shape. The high frequency signal terminals, the outer shells surrounding peripheries of the high frequency signal terminals, and the inner shells, which are disposed on a second symmetry axis form a linearly symmetrical shape with the second symmetry axis as a center line of the outer shells along a second direction orthogonal to the first direction in which the high frequency signal terminals are arranged.

The connector includes a housing to which contacts are attached and a frame which has an end in the first direction fixed to a board and which surrounds the housing. Of the frame, an end portion on a board side in the first direction is provided with a bending portion bent in a second direction, the second direction intersecting the first direction, and a pair of adjacent surfaces adjacent to opposite end surfaces of the bending portion in a third direction, the third direction intersecting each of the first direction and the second direction.

Abstract: Provided is a connector including a surrounding wall with an improved strength against an outward force. The connector of the invention includes a contact that contacts a counter contact of a counter connector, a housing to which the contact is fitted and attached, and a surrounding wall disposed to surround the housing. A gap is provided between the housing and the surrounding wall, and in a connector fitting state, the surrounding wall is in contact with a counter surrounding wall of the counter connector that has entered the gap. The surrounding wall is provided with a protrusion portion protruding outward in a second direction intersecting a first direction, and an end portion on a board side of the protrusion portion in the first direction is in contact with a board.

Abstract: A first hold-down includes a hold-down elastic piece supported like a cantilever beam by a reinforcing plate part. The hold-down elastic piece includes an elastic piece body extending from the reinforcing plate part, and a curve contact part formed at an end of the elastic piece body and projecting toward a CPU board beyond a CPU board opposed surface. A housing is formed in such a way that the curve contact part does not come into contact with the housing when the curve contact part no longer projects toward the CPU board beyond the CPU board opposed surface as a result of the curve contact part being elastically displaced toward an input-output board.

Abstract: A first hold-down includes a reinforcing plate part that covers a CPU board opposed surface. A suction cover includes a flat-plate suction plate part covering an electrical contact spring piece of each contact and thereby able to be sucked by a suction nozzle, a plurality of attachment spring pieces configured to catch on a connector so that the suction plate part is detachable from a connector, and a first main deformation restraining part projecting from the suction plate part toward the CPU board opposed surface in order to inhibit the suction plate part from being deformed toward the CPU board opposed surface in the state where the suction cover is attached to the connector. The first main deformation restraining part is disposed to come into contact with the reinforcing plate part when the suction plate part is deformed toward the CPU board opposed surface.

Abstract: A plug auxiliary fitting includes a plug side-wall facing portion facing a side surface of a plug housing. The plug side-wall facing portion includes a plug electrical connecting portion capable of coming into electrical contact with a receptacle auxiliary fitting, and a plug mating lock portion that cooperates with the receptacle auxiliary fitting to prevent a mating state between a plug connector and a receptacle connector from being released. The plug electrical connecting portion and the plug mating lock portion are, in a direction parallel to a plug-connector mounting surface of a plug-side board, adjacent to each other with a notch opened toward the plug-connector mounting surface of the plug-side board interposed therebetween. The plug mating lock portion is provided with a soldering portion solderable to the plug-connector mounting surface of the plug-side board.
