Claim 0:
1. A shielded locking system for securely closing a lid on an enclosure, comprising:
a locking assembly, the locking assembly comprising:
a guide frame having attachment tangs extending outwardly from said guide frame, the attachment tangs having a curved lip portion;
a spring-biased slide member positioned within the guide frame;
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, 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 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; and
fasteners for attaching the guide frame to a lower surface of the lid; and
a one-piece non-conductive cover positioned over and connected to the locking assembly having a profile to shield the L-bolt and said fasteners from electrical conductivity from within the enclosure and prevent electrical shock during operation of the locking assembly;
wherein the one-piece non-conductive cover includes recesses for receipt of and passage through of the attachment tangs extending from the guide frame and wherein the curved lip portion of the attachment tangs extend outwardly beyond the recesses to engage the one-piece non-conductive cover away from the recesses to lock the one-piece non-conductive cover to the locking assembly.
