1. A connector connection structure comprising:
a first connector;
a second connector electrically connected to the first connector;
a unit to which the first connector is ground-connected; and
a seal member configured to seal a gap between the first connector and the unit,
wherein the unit has a hole portion,
wherein the hole portion includes a first portion that is located on one side of the hole portion, and a second portion that is located on the other side of the hole portion with respect, to the first portion and the second portion has a diameter smaller than a diameter of the first portion,
wherein the first connector
includes a terminal portion to be inserted into the hole portion, a housing accommodating the terminal portion, an electric wire to which the terminal portion is connected at one end, and a shield shell provided with a contact portion having a contact part that is to abut an inner peripheral surface of the second portion, and
is electrically connected to the second connector via the hole portion,
wherein the electric wire includes a core wire connected to the terminal portion, a first insulating coating covering an outer periphery of the core wire, a shield member covering an outer periphery of the first insulating coating, and a second insulating coating covering an outer periphery of the shield member so that a part of the shield member is exposed to an outside,
wherein the seal member is positioned between the housing and an inner peripheral surface of the first portion, and
wherein in the connector connection structure,
a radius of the first portion is larger than a distance from a central axis of the electric wire to the contact part of the contact portion in a neutral state,
the part of the shield member exposed to the outside is connected to the shield shell, and the contact part of the contact portion abuts the inner peripheral surface of the second portion, so that a ground connection between the shield member and the unit is established, and
the core wire is connected to the terminal portion of the first connector and the terminal portion of the first connector is connected to a terminal portion of the second connector, so that the core wire is electrically connected to the terminal portion of the second connector.
