An electrical connector includes: an insulative base having a top surface, a bottom surface, and plural holes extending through the top surface and the bottom surface; a group of contacts mounted to corresponding holes, each contact having an upper contacting arm and a side portion; and a standoff secured to the side portion.

A plug-in mobile peripheral component interconnect express module connector is disclosed, comprising a plastic body, and a first terminal set and a second terminal set disposed relatively in the plastic body. The plastic body includes transversely penetrated slots, an upper end surface of the slots has intermittently plural upper magazines, and a lower end surface has intermittently plural lower magazines. The first terminal set includes plural first elastic terminals inserted in the upper magazines, and the second terminal set includes plural second elastic terminals inserted in the lower magazines. Each first elastic terminal is opposed to each second elastic terminal, forming a holding gap. A motherboard is inserted between the first elastic terminals and the second elastic terminals from a side, and an MXM board is inserted between the first elastic terminals and the second elastic terminals from the other side.

An electrical connector includes an insulating case and a first terminal set including a first grounding terminal set, a first signal terminal set and a second signal terminal set arranged at intervals in the horizontal direction. The first grounding terminal set includes a first grounding terminal, a second grounding terminal and a third grounding terminal. The first signal terminal set is vertically staggered between the first grounding terminal and the second grounding terminal and includes a first signal terminal and a second signal terminal arranged at intervals in the vertical direction. The second signal terminal set is vertically staggered between the second grounding terminal and the third grounding terminal and includes a third signal terminal and a fourth signal terminal arranged at intervals in the vertical direction.

A diagnostic imaging catheter is disclosed, which is capable of preventing a solution from an internal space of a hub from flowing into a portion communicating with the internal space of the hub and to which the signal lines such as the optical fiber and the electric signal cable are electrically or optically connected. The optical diagnostic catheter includes a rotatable drive shaft, an elongated sheath configured to be inserted into a biological lumen, a hub that includes a port connected to the sheath for supplying the solution, a connector portion that includes an optical connector accommodated in an internal space of the hub and optically connected to an external optical connector, a first seal portion that prevents the solution from the port from flowing into a first connection portion, and a second seal portion that prevents the solution from the port from flowing into a second connection portion.

There is provided a battery charger configured to charge a battery including a battery terminal. The battery charger includes a receiving portion in a form of a recess, and a charging terminal provided in the receiving portion. The battery is attachable to and detachable from the receiving portion. The receiving portion includes a holding portion configured to selectively hold the battery in the receiving portion at one of a first posture and a second posture different from the first posture. When the battery is in the first posture, the battery terminal is in contact with the charging terminal to allow the battery to be charged. When the battery is in the second posture, the battery terminal is separated from the charging terminal.

A socket includes a housing and a plurality of contacts. The housing is formed in a box-shape with an opening and is provided with a matrix of through holes at a bottom portion. The plurality of contacts includes ground contacts and signal contacts which are arranged so as to be aligned alternately in a predetermined array direction by one or a plurality of them and are passed through the through holes. The ground contacts adjacent to each other in the array direction are short-circuited.

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.

Terminals have a retained portion located forwardly of a receiving space and retained in a housing, and a contact arm portion that extends toward the rear from the retained portion; a contact arm portion has a contact portion that protrudes toward the receiving space in the connector thickness direction perpendicular to the forward-backward direction and the terminal array direction and is capable of contacting the counterpart connect body; a contact portion faces the interior surface of the receiving space across a gap in the connector thickness direction; the terminals have an extension portion located forwardly of the contact portion; the extension portion has a reflective portion in the rear end portion thereof; the reflective portion has a rear end face within a range that includes the protruding end of the contact portion when viewed from the rear; and the rear end face is formed as a reflecting surface.

A card connector, a card holder, and a terminal device, where the card connector includes a plurality of first terminals and one or more second terminals. The first terminals are arranged to form a first card access area that installs a first card, and the first terminals are configured to be electrically coupled to the first card. The one or more second terminals are distributed on a periphery of the first card access area, the first terminals and the one or more second terminals form a second card access area that installs a second card, and the first terminals and the one or more second terminals are configured to be electrically coupled to the second card.

A socket connector includes a housing that is made of insulating resin and have a peripheral wall and a bottom plate, the peripheral wall projecting upward from an edge of the bottom plate, a plurality of contacts that are held by the bottom plate, an upper cover member that is disposed above a semiconductor package accommodated in the housing, holds the semiconductor package downward and thereby brings the semiconductor package into electrical contact with the plurality of contacts, and a block and a block that project upward beyond the peripheral wall. The upper cover member has relief holes in which the block and the block is to be inserted at positions opposed to the block and the block in a vertical direction.
