Socket connector and manufacturing method thereof

A method of manufacturing a socket connector,

• the socket connector comprising:
• a housing in which an island part and a peripheral wall surrounding the island part project upward from a bottom plate;
• a plurality of contacts arranged in the housing;
• and
• two protective metal fittings,
• the peripheral wall including two long walls extending in a pitch direction of the plurality of contacts, and
• each of the protective metal fittings including
• a protective part placed at an island end part being an end of the island part in the pitch direction for protecting the island end part,
• two arm parts extending from the protective part toward the two long walls, respectively, and
• two press-fitting parts placed at distal ends of the two arm parts and to be press-fit into the two long walls, respectively, and
• the method comprising:
• a cutting step of forming the protective part of the two protective metal fittings by cutting a metal plate in such a way that a dome part in a symmetrical shape formed by drawing in the metal plate is split into two halves along a line of symmetry;
• and
• a press-fitting step of press-fitting the two press-fitting parts into the two long walls, respectively.
