摘要： IN A CONNECTOR HAVING A GROUP OF CONTACTS ARRAYED AT NARROW PITCHES ON A BASE MEMBER, A CONTACT FIXTURE DEVICE IS FORMED SEPARATELY FROM THE BASE MEMBER FORMING A CONNECTOR BODY. THE CONTACT FIXTURE DEVICE IS PROVIDED WITH A RETAINING CLAW ADAPTED TO SECURE THE FIXTURE DEVICE TO THE BASE MEMBER. THE CONTACT FIXTURE DEVICE IS FURTHER PROVIDED WITH A PRESSER PORTION DISPOSED ACROSS A GROUP OF SEAT ELEMENTS OF THE GROUP OF CONTACTS. THE PRESSER PORTION IS LAID ACROSS THE GROUP OF SEAT ELEMENTS TO URGE THE GROUP OF SEAT ELEMENTS AGAINST A SURFACE OF THE BASE MEMBER WHEN THE FIXTURE DEVICE IS SECURED TO THE BASE MEMBER THROUGH THE RETAINING CLAW. BY THIS, THE GROUP OF CONTACTS CAN BE ARRAYED ON THE BASE MEMBER.(FIG 3)
