  In the case of the socket connector according to Patent Document 1 or Patent Document 2 described above, one mating connection object such as a semiconductor element module or a package can be housed and inserted into the housing portion from one direction, and the other side opposite to the one direction. The other side of the other connection object such as a printed wiring board can be connected in the direction, but the repulsion at the time of contact of each contact when one of the other connection objects is accommodated and inserted into the accommodating part. Because the structure is such that the force is received only by the outer wall of one counterpart connection object (usually the outer wall of the shell), terminals other than the terminals arranged near the mounting surface (lower surface) of the other counterpart connection object The structural inconvenience of being unable to connect to what has is a problem.

  That is, in recent years, the multi-functionality and high performance of the semiconductor device are particularly remarkable. For example, as in the case of a CMOS package, even in one counterpart connection object, in a place in a tall direction other than the vicinity of the mounting surface. Since a structure having a connection terminal has been developed, an improvement in basic structure is required for a conventional structure in which such a product cannot be connected.

  The present invention has been made to solve such problems, and the technical problem is that even if the mating connection object to be accommodated and inserted has a connection terminal other than the vicinity of the mounting surface, the present invention is stable. It is an object of the present invention to provide a socket connector having a connectable structure.
