Connector, method for connecting contact pin, contact pin, and storage medium

A method for connecting a contact pin, the method connecting the contact pin of a connector to an electrode of a connection body by mounting the connection body in the connector by relatively displacing the connection body in a first direction, the method comprising:

• causing a second protrusion of the contact pin to have sliding contact with a surface of the electrode;
• and
• causing a first protrusion of the contact pin to contact a region of the surface of the electrode after the second protrusion has slid over the region,
• the first protrusion being located at the first-direction side of the second protrusion.

A contact pin, comprising:

• an elastic contact part including
• a first protrusion protruding upward, and
• a second protrusion separated from the first protrusion in a longitudinal direction, the second protrusion protruding upward;
• a holding part linked to the elastic contact part, the holding part being held by a housing, the housing including an insulating resin;
• and
• a connection part linked to the holding part, the connection part being exposed from under the housing.

A storage medium connectable to a connector,

• the connector including:
• a casing including a storage portion;
• and
• a contact pin including an elastic contact part,
• the storage medium being mounted to the storage portion by being relatively displaced in a first direction,
• the storage medium comprising:
• an electrode surface electrically connected with a first protrusion of the elastic contact part,
• the first protrusion protruding toward the storage portion,
• a second protrusion of the elastic contact part sliding on the electrode surface,
• the second protrusion being separated from the first protrusion and protruding toward a direction crossing the first direction.
