US Patent 9728882 Connector

A first contact part of a first terminal includes a linear part extending linearly in an insertion direction of an insertion protrusion, and a termination part of the linear part; and a first contact part of a second terminal includes a linear part extending linearly in an insertion direction of an insertion protrusion, and a termination part of the linear part; where, when an insertion protrusion is inserted into an insertion recess such that a first connector and a second connector achieve a completely mated state, the termination part of the linear part of the first contact part of the second terminal is positioned more in front of the insertion direction of the insertion protrusion than the termination part of the linear part of the first contact part of the first terminal.
