Abstract

A guiding function of an annular contact upon mating/removal with/from an opposing connector can be maintained well with a simple configuration. An annular contact is formed with an unruptured annular member having no ruptured part in a circumferential direction and continued in the circumferential direction. As a result, compared with a conventional annular contact having ruptured parts in the circumferential direction, rigidity is increased while maintaining necessary elasticity; and, for example even when an opposing connector is mated or removed in a direction inclined in an axial direction with respect to the axial direction of the annular shape, conventional twisting deformation is suppressed in the annular contact, and the opposing connector is stably guided along the axial direction of the annular shape, thereby well maintaining a mating guiding function of the annular contact.

First claim

What is claimed is:

1. A coaxial electrical connector having an annular contact formed so as to have an annular shape, the coaxial electrical connector configured so that an opposing connector is mated or removed therewith/therefrom along an axial direction of an annular opening, through the annular opening, the annular opening being formed in a ground main-body part of the annular contact, the ground main-body part being provided with a connection leg part configured to be placed on and solder-joined with a printed wiring board, wherein:
the ground main-body part of the annular contact is formed of an unruptured annular member integrally continued in a circumferential direction at a portion between the annular opening and the connection leg part of the ground main-body part;
a plurality of through holes are formed between the annular opening and the connection leg part of the ground main-body part of the annular contact at an approximately equal interval in the circumferential direction; and
an annular portion which forms the annular opening extends in a curved shape toward an inner side or an outer side in a radial direction of the annular opening.

2. A coaxial electrical connector device comprising the coaxial electrical connector according to claim 1 and the printed wiring board on which the coaxial electrical connector is mounted, wherein:
the annular contact of the coaxial electrical connector is a ground contact;
a signal contact is disposed in an inner side in a radial direction of the ground contact;
an electrically-conductive ground path to be connected to the ground contact and an electrically-conductive signal path to be connected to the signal contact are formed on the printed wiring board; and
the electrically-conductive signal path is formed in a center region of the radial direction of the ground contact.

3. The coaxial electrical connector according to claim 1 , wherein the plurality of through holes disperse stress generated in the annular opening.
