Abstract: A fastener includes a clip including a flexible head having an outer surface configured to engage and edge of a first slot in a first panel when the flexible head is inserted therein and a retainer configured to be inserted into a channel within the flexible head to impede flexing of the flexible head thereby retain the flexible head in the first slot. The clip may further include at least one member extending from the head and configured to engage a second slot in a second panel to hold the first and second panels together when the first and second slots are positioned in an opposing relationship. In some embodiments, the at least one member may include first and second spring arm members extending from the head and having outer surfaces configured to engage edges of the second slot when inserted therein. Methods using such fasteners are also discussed.

Abstract: A terminal block for conductively coupling multiple pairs of electrical wires includes a deadfront cover mounted onto a non-conductive base so as to define multiple pairs of wire receiving receptacles, each pair of wire receiving receptacles being electrically connected together via a conductive bus bar. As one feature of the present invention, a conductive shunt can be disposed by means of a manually operable shunt switch to selectively contact all of the bus bars in order to discharge any current present thereon. As another feature of the present invention, a plurality of finger-safe captive screw assemblies are retained within the cover, each captive screw assembly including a screw which can be driven into a threaded bore formed in one end of a corresponding bus bar. As yet another feature of the present invention, multiple pairs of interchangeable end caps can be removably snap-fit mounted on the base to enable the terminal block to be retained onto a wide variety of different surfaces.
