A semiconductor device, including a semiconductor element; a case having a frame portion, which has an inner periphery that surrounds a housing space for accommodating the semiconductor element; and a lid covering the housing space. The inner periphery of the frame portion has a stepped portion formed thereon, the stepped portion including a step supporting surface positioned at a level lower than a front surface of the frame portion and being approximately parallel to the front surface of the frame portion. The lid has a lateral surface surrounding the lid, and a front surface and a bottom surface approximately parallel to the step supporting surface.

A connector has a fixing hole in an intermediate portion of a terminal member, and has an engagement portion projecting downward in a thickness direction, at an end portion at a front end side of the fixing hole. Therefore, when the terminal member is attached to a housing, movement of the terminal member toward a rear end side can be restricted by fitting a projection portion of the housing into the fixing hole. Furthermore, since the engagement portion is provided to the terminal member, movement of the terminal member toward the rear end side can be restricted by engaging the engagement portion with a front end surface of a protrusion portion of the housing.

A press fit terminal that includes a terminal metal fitting with a first end and a second end, the terminal metal fitting including: a pressure contact part that is at the first end and that is configured to be press-fit into a through-hole of a printed circuit board and made to be electrically conductive with a conductor at an inner surface of the through-hole, and a connecting part that is at the second end and that is configured to be connected to a mating member.

A board terminal includes a metal wire material with a first end and a second end, the metal wire material including: a middle part that is between the first end and the second end, a connecting part that is at the first end and that is configured to be connected to a mating member, and a conductive part that is at the second end and that is configured to be inserted through a through-hole of a printed circuit board and is made to be conductive with an electrically conductive path, wherein: a first side edge of the connecting part is cut away from the first end toward the middle part for a specified length between the first end and the second end, and a width of the connecting part is narrower than the middle part, and a pressing part is formed by a step surface that is between the connecting part and the middle part.

A modular jack connector includes a housing defining a first direction and a second direction perpendicular to the first direction. A plurality of terminals are disposed in the housing. Each terminal having a body portion and a contact end portion connected to the body portion. Each contact end has a contact surface facing the first direction for connecting to a counterpart connector. The contact surface is a rolled surface of a metal sheet from which the contact terminals are formed. Plating process becomes more efficient and plating quality is improved, resulting in terminals with high contact surface quality being made for better electrical connectivity when connected to counterpart connectors.

A connector system includes a connector mounted on a circuit board. The circuit board has deeper backdrilled vias and the connector has modified signal terminal that can mate with the backdrilled vias so as to provide a surprising increase in the performance of signal traces provided in the top layers of the circuit board.

A press-fit terminal includes a press-fit portion to be inserted into a through hole of a circuit board. The press-fit portion includes a plurality of protruding portions extending outward from a cross-sectional center of the press-fit portion, and a distance between an outer edge of each of the protruding portions and the cross-sectional center is continuously decreased toward the distal end of the press-fit portion.
