<p><P>PROBLEM TO BE SOLVED: To provide an insertion and pull-out structure for a connector, with which a simple and prompt operation of insertion coupling and separation is performed. <P>SOLUTION: The insertion and pull-out structure of the connector is composed of first printed circuit board 101, onto the receptacle side of which at least two spacers 2 with internal screws 21 are equipped near the connector 12, and in a second printed circuit board 102, which is equipped with through-holes 3 for a screw object, and at least two through-holes 4 near each through-hole 3 for screw attachment. About a screw object 5, which fixes by screwing to the screws 21 of the spacer 2 through the through-hole 3, there are equipped with plain washer 52, being supported by external screws 51, and with proximal 61, which is loosely fitted between a head part 51a of the screw object 5 and the plain washer 52. The proximal 61 has an extension 62 extended in an axial direction of the screw object 5 and has a narrower width than the through-hole 4. The proximal 61 also has a projection 63, which projects from the extension 62 approximately parallel to the proximal 61. In the state of clench of ball grid array connector 1, part of the extension 62 is arranged in the through-hole 4 for screw attachment 6. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
