Abstract: A method for manufacturing lamp shell to improve structural strength and light penetration includes steps of: providing a plastic material, injecting the plastic material into a injection molding equipment to form a preform containing a first space with an opening and a connecting section at one end and a closed another end to form a light penetrating section, and placing the preform in a blow molding equipment and blowing the plastic material by injecting gas to inflate the preform through gas pressure to form a second space at a greater size than the first space to become a lamp shell. The lamp shell thus formed has a greater structural strength to meet safety requirements, and also provides improved light penetration, and can reduce material consumption of the lamp shell to save production cost.

Abstract: A blocking member is sized and shaped to be installed beneath a trigger or triggers of a duplex connector. The blocking member prevents depression of the trigger(s) of the duplex connector and hence prevents depression of latches to release the plugs of the duplex connector from mated receptacles. The blocking member does not block actuation of the latches of the duplex connector. Through the use of a tool, the trigger(s) may be bypassed and the latches operated directly by the tool to release the plugs of the duplex connector when mated to receptacles.
