According to an embodiment, high-frequency signal transmission device includes a connector and a wiring board with two cable ends. The connector includes contact terminals with signal contact terminals and ground contact terminals. In a wiring board, signal contact pads, ground contact pads and one or more ground layers are formed on at least one of the cable ends. The ground contact terminal includes an arm portion bent so as to locally abut against the ground contact pad at a contact portion. The contact portion of the arm portion is positioned so as to (i) at least partially abut against a surface of a covering portion of the ground contact pad covering the first penetrating electrode directly above the first penetrating electrode, or (ii) abut against the ground contact pad near an outer periphery of the covering portion, when the wiring board is electrically connected to the connector.

Mezzanine connector housing

According to an embodiment, a housing of a high-speed transmission connector fitted to a connector of a counterpart substrate via a frontage. The housing of the first aspect includes: a bottom plate forming a bottom of the frontage and being provided with at least one boss on a surface opposite to the frontage side; a pair of first side walls facing each other in a first direction with the frontage sandwiched therebetween; and a pair of second side walls facing each other in a second direction orthogonal to the first direction with the frontage sandwiched therebetween. The bottom plate is provided with first through holes for tolerance measurement having inner peripheral surfaces including side wall surfaces of the first side walls in the same planes and/or second through holes for tolerance measurement having inner peripheral surfaces including side wall surfaces of the second side walls in the same planes.

Receptacle connector

An interface connector makes parts to be fitted by insertion hold the state where a receptacle and a plug are fitted, and removes the plug easily from the receptacle when load is applied to the plug from a direction other than the insertion direction. In the interface connector (), the plug () has an inserting projection part () in which a plurality of plug terminals () are disposed in upper and lower faces (and). The inserting projection part () is provided with a plurality of plug terminals () that project freely moving in and out of the upper and lower faces (and) of the insertion projection part () by elastic deformation, and, when the inserting projection part () is inserted in the insertion slot () of the receptacle (), a plurality of plug terminals () press against a plurality of receptacle terminals () provided in the receptacle () such that the insertion projection part () is held removably in receptacle () and is removed from the receptacle () when load is applied from a direction other than the insertion direction.
