Connector
A connector includes: a cylindrical terminal to be electrically connected with a cylindrical counterpart terminal; an internal terminal located in the cylindrical terminal; and a housing holding the cylindrical terminal. The cylindrical terminal has a contact portion configured by bending a plate-shaped conductor into a cylindrical shape to contact one edge portion of the conductor with the other edge portion of the conductor. The one edge portion has a recessed shape at its circumferential end portion by reducing its thickness outwardly in a radial direction of the cylindrical terminal to configure one reduced thickness portion. The other edge portion has a recessed shape at its circumferential end portion by reducing its thickness inwardly in the radial direction to configure the other reduced thickness portion. The contact portion is configured by overlapping the one reduced thickness portion and the other reduced thickness portion.
1. A connector comprising:
a cylindrical terminal to be electrically connected with a cylindrical counterpart terminal;
an internal terminal located in the cylindrical terminal; and
a housing holding the cylindrical terminal,
the cylindrical terminal having a contact portion configured by bending a conductor having a plate-shape into a cylindrical shape to contact one edge portion of the conductor with an opposite other edge portion of the conductor,
the one edge portion having a recessed shape at its circumferential end portion by reducing its thickness outwardly in a radial direction of the cylindrical terminal to configure one reduced thickness portion,
the other edge portion having a recessed shape at its circumferential end portion by reducing its thickness inwardly in the radial direction to configure an opposite other reduced thickness portion,
the contact portion being configured by overlapping the one reduced thickness portion and the other reduced thickness portion.
2. The connector according to claim 1 , wherein
the one reduced thickness portion and the other reduced thickness portion are pressed against each other in a circumferential direction of the cylindrical terminal.
3. The connector according to claim 1 , wherein
the cylindrical terminal has: a large diameter portion to contact with the counterpart terminal; and a small diameter portion having a smaller diameter than the large diameter portion and to held in the housing,
the contact portion extends in an axial direction of the cylindrical terminal over both of the large diameter portion and the small diameter portion.
4. The connector according to claim 1 , wherein
the one reduced thickness portion of the one edge portion is overlapped over the other reduced thickness portion of the other edge portion in the radial direction.
5. The connector according to claim 4 , wherein
the one reduced thickness portion of the one edge portion and the other reduced thickness portion of the other edge portion each extend along an entire length of the cylindrical terminal,
the entire length of the cylindrical terminal being along a longitudinal direction that is perpendicular to both the radial direction and a circumferential direction of the cylindrical terminal.
