Connector socket with contact enlarged base sections inserted in holding chamber attachment grooves and stopping projections in chamber to prevent contact from being withdrawn from chamber

Claim 1

A connector socket comprising: a connector mold; a plug insertion opening on a surface of said connector mold for receiving a plug section of a connector plug; at least one contact holding chamber in said connector mold; a pair of contacts disposed within said contact holding chamber; said pair of contacts facing each other along a direction perpendicular to a length of said connector mold; said pair of contacts including deformable pressure-contact ends that are pressed into contact with a plug contact of said plug section when said connector plug is inserted into said plug insertion opening; a center stopper integrally formed on each of said contacts; said center stopper being on an intermediate portion of said contacts; said center stopper is wider than an adjacent portion of said contact; an engagement surface on an inner wall surface of said contact holding chamber; and said engagement surface being positioned to engage said center stopper to resist displacement of said center stopper beyond a predetermined displacement, whereby excessive displacement of said contact during withdrawal of said plug contact is prevented, said at least one contact holding chamber being opened to opposite surfaces of said connector mold; said at least one contact holding chamber including first and second base attachment grooves extending inward from said opposite surfaces; said contacts including enlarged base sections; and said enlarged base sections are inserted into said contact holding chamber by sliding in said base attachment grooves through said opposite surfaces.
