Technical Field

The invention relates to a connector and a wire harness.

Background

As a conventional connector, for example, patent document 1 discloses a connector including: the terminal, inner shell (inside part), shield cover (sealed), shell (outside part), external sealing gasket (outside sealed) and internal sealing gasket (inside sealed). The terminal can extend along the insertion and extraction direction and be electrically connected with a mating terminal of a mating device. The inner housing accommodates the terminal inside and is formed of an electrically insulating synthetic resin. The shield case is located outside the inner case and accommodates the inner case inside. The housing is made of electrically insulating synthetic resin, is located outside the shield case, and accommodates the shield case inside.

The connector is pre-configured to bring the outer and inner gaskets into contact with the mating side device. The housing has a flange portion, and the flange portion and the mating-side device are fixed to each other by fastening force of a bolt and a nut. The outer and inner gaskets compressed in the insertion and extraction direction of the terminal prevent water from entering the terminal accommodating portion in a state where the connector is mounted on the mating side device.

Technical problem to be solved by the invention

However, in a connector used in a vehicle such as an automobile, a force may be applied in a pulling-out direction by vibration or the like generated when the vehicle travels. When such a force is applied to the conventional connector, a gap may be generated between the connector and the mating electronic device, and a gap may be generated between the mating-side device and the outer gasket and between the mating-side device and the inner gasket. Therefore, the conventional connector has room for improvement in terms of improving the waterproof performance.
