Patent ID: 8790121

Claim:
An electrical connector for electrically connecting a terminal part of a signal transmission medium to a wiring pattern of a wall part of a product chassis, the wiring pattern formed on a surface of the wall part constituting the product chassis of an electronic device having a predetermined electronic circuit, the electrical connector having a main body part to which an electrically-conductive contact having a contact part elastically in contact with the wiring pattern is attached, wherein a coupling projection part composed of a plate-like member is provided in the wall part constituting the product chassis so as to project like a cantilever, and the main body part is configured to be able to be mated with the coupling projection part, wherein the wiring pattern is provided with a contact part exposed from at least one of upper and lower both surfaces of the plate-like member constituting the coupling projection part, wherein the electrically-conductive contact is disposed so as to extend along a direction approximately parallel to a direction of mating with the coupling projection part, wherein the contact part of the electrically-conductive contact is disposed so as to sandwich the coupling projection part from the upper and lower both surfaces and be in contact with the contact part of the wiring pattern in a state in which the main body part is mated with the coupling projection part, wherein the electrically-conductive contact is composed of a signal contact for transmitting a signal, ground contacts for grounding are disposed on both sides of the signal contact, and a ground coupling plate integrally coupling the ground contacts for grounding is disposed on both sides of the signal contact to each other is provided, and wherein the ground coupling plate is disposed on a side closer to a front than a mating-direction front-end part of the signal contact is.
