These automotive crimp terminals are equivalent to 040 and 070 tab width items. The contact portion of the F connector side has been given a double structure to make these connectors compatible with low insertion force and high contact pressure at the time of coupling. In this design, the contact portion is housed in a box that is formed by a press. This prevents the contact portion from being misshapen by an external force. The design of the waterproof connectors uses a 2-stage sequence having a low insertion force.
