Abstract A socket for a printed circuit board which includes a housing having an insertion opening for receiving the printed circuit board. This opening is provided between first and second opposed walls wherein the first wall is shorter than the second wall. A plurality of spring contacts having contacts project from both of the walls into the insertion opening and form rows extending along the axis of the insertion opening. A pair of latch arms extend from those portions of said housing which are close to the ends of the insertion opening so they may be pushed outwardly by the sides of the printed circuit board when the printed circuit board is rotated in such a direction as to press the contacts. They are returned to initial positions by virtue of their elastic force when the printed circuit board passes so as to then hold the board in position. Holder members partially project from the first wall and a latch guide arranged between the holder members and the latch arms to prevent the printed circuit board urged by the spring contacts from rotating at an angle more than a predetermined value when the latch arms release the printed circuit boards. The housing and said latch arms are formed of an integral member made of insulating material.
A socket for a printed circuit board, comprising: a housing having an insertion opening having an axis for receiving the printed circuit board, said opening provided between first and second opposed walls wherein the first wall is shorter than the second wall; a plurality of spring contacts having contacts projecting from both of the walls into the insertion opening and forming rows extending along the axis of the insertion opening; a pair of latch arms extending from those portions of said housing which are close to the ends of the insertion opening, to be pushed outwards by the sides of the printed circuit board when the printed circuit board is rotated in such a direction as to press the contacts, and to be returned to initial positions by virtue of their elastic force when the printed circuit board passes, so as to hold the printed circuit board against an urging force of said spring contacts; holder members partially projecting from the first wall and a latch guide arranged between the holder members and the latch arms, for preventing the printed circuit board urged by the spring contacts from rotating at an angle more than a predetermined value when the latch arms release the printed circuit board; wherein said housing and said latch arms are formed of an integral member made of insulating material.
