Case closing structure

摘要

A case closing structure (1) includes a device case (10) including a case wall (11). A shield connector (20) is mounted on the case wall (11) and has a work opening (22H) and a seal cover (40) for closing the work opening (22H). The shield connector (20) includes a mounting surface (31F) and nut holes (35H) open on the side of the mounting surface (31F). The seal cover (40) includes mounting plates (54) arranged along the mounting surface (31F) and having third bolt insertion holes (55), and shell fixing bolts (B) inserted through the third bolt insertion holes (55) and screwed into nut holes (35H). The case wall (11) includes positioning pins (13) extending perpendicular to the mounting surface (31F) and configured to restrict the rotation of the seal cover (40) with respect to the device case (10) by coming into contact with the mounting plate portions (54).
