  • Patent number: 9673561
    Abstract: It is aimed to prevent a tape from being displaced in the case of taping a connector. In the case of fixing a connector to a wiring harness (WH) by winding a tape, upper-surface side ribs (9) extending in a direction substantially perpendicular to a winding direction of a tape (T) are formed to project on opposite end parts of the upper surface of a connector housing (1). In the case of taping, a winding width is set to be wider than the upper-surface side ribs (9). Since this causes opposite end parts of the upper-surface side ribs (9) in an extending direction to serve as parts for catching the tape (T), a situation where the tape (T) is displaced in the extending direction of the upper-surface side ribs (9) can be prevented.
