CONNECTOR

PROBLEM TO BE SOLVED: To improve productivity by constituting a connector such that even in the case of making a mistake in a terminal insertion position to an insulator, this inferiority can be easily discovered, relating to the connector. SOLUTION: A connector 21 comprises a first terminal 12 having a contact in one end to straight extend an external connection terminal connected to an insulator fixed part continued to this contact, second terminal 13 having a contact in one end to form an external connection terminal connected to an insulator fixed part continued to this contact in an offset bending tip and an insulator 22 formed with holes capable of securing each terminal 12, 13 by the insulator fixed part. The insulator 22 is constituted by providing a protrusion 22b having a height, where an offset bending region can be brought into contact before securing the second terminal 13, in an offset bending directional position of the second terminal 13 positioned in the same row in the vicinity of a terminal insertion side opening of the hole securing the first terminal 12.
