Claim 0:
1. A shielded locking system for securely closing a lid on an enclosure, comprising:
a spring-biased slide member positioned within a non-conductive cover rigidly attached to an underside of the lid by fasteners;
an L-bolt having a leg portion thereof coupled to the slide member;
the L-bolt having an elongated shaft portion thereof rotatable in a slotted housing that securely retains the L-bolt under the lid;
the slide member having a latch portion thereof adapted to engage a rim or another abutment on an inside of the enclosure when the lid is forced down over an opening in the enclosure, such a downward force on the lid progressively causing the latch to retract against a spring bias, from contact with the rim or abutment, and then snap the latch into a spring-biased locking position under the rim or abutment;
the shaft portion of the L-bolt is accessible from the exterior of the lid for rotating the L-bolt to retract the latch against the spring-bias and from its locking position sufficiently for removing the lid from the enclosure,
the non-conductive cover having a channel for receipt of and guiding travel of the spring-biased slide member within the non-conductive cover, the channel being formed by an end wall, a first side wall, a second side wall and a base wall of the non-conductive cover, the end wall located at an end of the first side wall, the second side wall and the base wall,
wherein the non-conductive cover further includes a rigid rib wall extending inwardly into the channel from the end wall and the base wall and in between and spaced from the first side wall and the second side wall for engaging an end of a spring in the slide member at a distance away from the end wall, and
wherein the non-conductive cover shields the L-bolt, spring and fasteners from electrical conductivity from within the enclosure.
