An electronic device includes a substrate, and a press-fit terminal. The substrate includes a first surface, a second surface opposite to the first surface in a thickness direction of the substrate, a through hole, and an electrode formed in the first surface, the second surface, and a wall of the through hole. The press-fit terminal is fit into the through hole from the first surface while being elastically deformed. The press-fit terminal is connected to the electrode by a reaction force due to the elastic deformation of the press-fit terminal. The substrate includes (i) a core layer that is overlapped, in the thickness direction, with a contact portion of the electrode with the press-fit terminal, and (ii) a flexible layer that is at a position closer to the first surface than the core layer is to. The flexible layer has a lower elastic modulus than the core layer.

Electronic device

A card edge connector for electrically connecting harnesses to contact electrodes that are located in different positions on a surface of an electronic substrate in an insertion direction includes a housing, harness terminals, and relay terminals. The housing defines a substrate insertion hole for receiving the electronic substrate. The harness terminals are separately connected to the harnesses and located in different positions in a height direction perpendicular to the insertion direction. The relay terminals separately connect the harness terminals to the contact electrodes upon insertion of the electronic substrate into the substrate insertion hole.

Card edge connector and method of manufacturing the same

A card edge connector for electrically coupling between contact electrodes on an electric circuit board and harnesses includes: a housing with a board insertion opening; harness terminals coupling with the harnesses; and junction terminals coupling between contact electrodes and harness terminals. The contact electrodes include first and second contact electrodes on both of first and second surfaces of the board. Each first contact electrode is nearer one end of the board than each second contact electrode. The first and second contact electrodes on the first or second surface are aligned alternately along with a width direction of the board. A first or second end of the junction terminal contacting the contact electrode on the first or second surface extends from a first or second inner wall of the board insertion opening to reach a centerline of the board.

Card edge connector and method for assembling the same

A card edge connector includes a housing, a first conductive part, a second conductive part, a connecting element, a first harness, and a second harness. The housing has an insertion hole for receiving an electronic substrate therein. The first conductive part and the second conductive part are disposed in the insertion hole and are configured to come in contact with respective terminals disposed on a surface of the electronic substrate. The connecting element is coupled with the second conductive part and extends in a direction approximately vertical to a planer direction of the electronic substrate so as to be away from the surface of the electronic substrate. The first harness is coupled with the first conductive part and the second harness penetrates a penetrated part of the connecting element.

A card edge connector includes a housing, a first conductive part, a second conductive part, a supporting conductive part, a connecting element, a first harness, and a second harness. The housing has an insertion hole for receiving an electronic substrate therein. The first conductive part and the second conductive part are disposed in the insertion hole and are configured to come in contact with respective terminals disposed on a surface of the electronic substrate. The supporting conductive part is disposed in the housing in such a manner that supporting conductive part is farther away from the surface of the electronic substrate than the first conductive part is. The connecting element couples the second conductive part and the supporting conductive part, the first harness is coupled with the first conductive part, and the second harness is coupled with the supporting conductive part.
