BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a board used in OA equipment requiring a flexible memory capacity increase / decrease or a function change, for example, a personal computer or an EWS (engineering workstation). In particular, it is used for connecting two boards (for example, a motherboard and a daughter board or a main board and a sub board).

[0002]

2. Description of the Related Art Conventionally, there are various types of connectors for connecting two substrates, and one of them is, for example, one shown in FIGS. This is because a plurality of contacts E mounted on the housing A are inserted into through holes of the motherboard F, and a daughter board B is inserted into the insertion groove C of the housing A at an angle as shown in FIG. , The daughter board B is rotated in the direction indicated by the arrow X in FIG. 9 and the two latches D attached to the upper portion of the housing A are pushed outward by the board B. The board D is vertically raised up to the inside of the latch D, and the surface of the board B is latched by the latch D to hold the board B in an upright state. At this time, daughter board B
And the motherboard F can be electrically connected via the contact E.

In order to remove the daughter board B mounted on the connector as shown in FIG. 9, the jig (a screwdriver or a ballpoint pen) or a fingertip is hooked on the release portion H of the latch D, and the latch D is pulled out. After tilting obliquely in the direction of arrow Y (outside), the daughter board B is tilted forward as shown in FIG. 8, and then the daughter board B is removed from the insertion groove C. For this reason, the release portion H of the latch D must be projected outside the housing A so that a jig, a finger or the like can be easily hooked. Therefore, in the connector of FIG. 9, the latch D is inserted into the housing A from above the housing A, and the release portion H is placed on the front receiving edge G.
