Abstract

An electrical connection device or binding post (10) for forming electrical connections with various types of electrical connectors has a body (24) adapted for being disposed in an aperture (14) of a mounting panel (18). A head (26) is movably disposed in a cavity (74) of the body and a collar (28) is movably disposed about the body. A spring (32) biases the head and collar in a secured position while depression of the head defines an open position. One or more bores (100) in the head align with one or more bores (78) in the body when the head is depressed for receiving a wire (108). An annular groove (130) is formed between the collar and a flange (86) on the body when the head is depressed for receiving a spade-type connector (138). The bores and groove are located in separate locations on the body so that the wire connection and spade connection do not physically interfere with one another. A longitudinal bore (112) is formed in the head for receiving a banana-type connector (114). The post body has two lower sections (56 and 58) with differing diameters forming a step or flange (68) therebetween. The lowest section (58) may be received within an aperture (62) on a circuit board (64) or ring terminal (200) for physical and electrical connection.
