Abstract: An extension wire socket includes a nonconductive U-shaped portion, a nonconductive chamber and at least one electrical connector supported therein. The U-shaped portion is defined by a base and opposed tabs extending from the base. The U-shaped portion snaps over insulated electrical conductors. The nonconductive chamber is adjacent to the base. The socket accepts the terminal end of an extension wire. Each connector includes a spiked prong for piercing the insulation of one of the conductors when the socket is attached to the conductors. Each connector also includes an insulation displacement terminal for attaching the terminal end of the extension wire thereto. The spiked prong is located in the U-shaped portion and the insulation displacement terminal is located in the chamber. The connector is slotted into the socket in a manner that protects most portions of it from exposure and unwanted flexing and stresses.

Abstract: Lighting trim attaches to lamp housing by mating one or more trim attachment regions with respective housing attachment regions. Each trim attachment region includes a finger thereon. The finger ends in a downwardly curved lip. Each housing attachment region includes a slot and a detent sector adjacent to and in communication with the slot. The trim's finger and the housing's slot are dimensioned so that the finger can pass through the housing slot when they are aligned with each other. The finger's lip becomes seated into the housing detent sector upon subsequent rotation of the trim with respect to the housing.
