Fiber optic enclosure having tamper resistant lock

A housing comprising:

• a first panel lying in a first plane and including a keeper;
• a support member spaced from the first panel;
• a door having a hinge edge hingedly connected to the support member and a free edge opposite the hinge edge, the door being shiftable between a first position with the free edge adjacent the first panel and keeper and a second position with the free edge spaced from the first panel and keeper;
• and
• a lock mounted on the door, the lock comprising a rotatable cylinder having an axis of rotation and a cam connected to the cylinder for rotation with the cylinder, said cam having a first end and a second end spaced from the first end by a cam body, the second end extending at an angle to the cam body and lying in a second plane;
• wherein, when the door is in the first position, the cam is shiftable from a first orientation with the cam second end spaced from the keeper to a second orientation with the cam second end overlying a side of the keeper opposite the cylinder to lock the door;
• and
• wherein:
• the keeper comprises an opening in the first panel;
• the opening extends through the first panel and has a continuous periphery;
• the first panel includes a first edge,
• the opening includes a first portion having a first width in a direction perpendicular to the first edge and a second portion having a second width in the direction, the second width being greater than the first width,
• the cam second end has a length in the direction, and
• the cam second end length is greater than the first width.

A housing comprising:

• a first panel lying in a first plane and having an inner side facing into the housing and an outer side opposite the inner side, a first edge and an opening having a side wall extending through the first panel and having a continuous periphery spaced from the first edge, the opening including a first portion having a first width in a direction perpendicular to the first edge and a second portion having a second width in the direction, the second width being greater than the first width,
• a second panel parallel to and spaced from the first panel;
• a door having a hinge edge hingedly connected to the second panel and a free edge opposite the hinge edge, the door being shiftable between a first position with the free edge in contact with the first panel and a second position with the free edge spaced from the first panel;
• a lock mounted on the door, the lock comprising a key actuated rotatable cylinder having an axis of rotation perpendicular to the door and a cam having a first end connected to the cylinder for rotation with the cylinder and a second end spaced from the first end by a cam body, the second end extending at an angle to the cam body and lying in a second plane parallel to the axis of rotation and having a length in the direction greater than the first width;
• wherein, when the door is in the first position, the cam is shiftable from a first orientation with the cam second end inside the housing to a second orientation with the cam second end overlying the first panel outer side, and
• wherein the cam body passes through the opening and engages the side wall of the opening to prevent the door from moving toward the second position when the cam is in the second orientation and the cam second end is spaced from the first panel when the cam body is located in the first portion of the opening.
