According to the connector of the present invention, at least two contact elements are assembled in the contact receiving hole of the insulator while being connected to the carrier, and the carrier is cut and removed after the assembly. The contact can be manufactured in the same assembling process as the conventional single contact.

Further, the second contact is displaced in the contact accommodating hole around one of the contact portion of the second contact contacting the connection object and one of the contact means of the first and second contacts. Therefore, it is possible to set the same displacement amount to each of the contact means.

Further, since the contact means of the first and second contacts are in contact with each other in a state where the contact element is incorporated in the contact accommodating hole, the contact element is not fitted in the insulator. Also, the contact means can be kept in contact with each other, and at the same time, the first and second contacts can be engaged with each other so as not to drop off in the contact receiving hole.

Further, since the first and second contacts are in contact with each other in a state of being incorporated in the contact receiving hole, the current path is linear and short, and a low inductance connector is obtained. Can be

Further, since the force with which the first and second contacts come into contact with each other is applied as a reaction force of the contact force of the connection object, no extra stress is applied to the spring portion, and the first and second contacts are not applied. The contact can be made small.

Further, when the connecting object and the insulator are fitted together, the amount of displacement of the second contact can be set to be as large as the displacement of the contact portion due to the pressing of the connecting object without requiring excessive operating force. A stable connection is possible.
