Electrical terminal block

A terminal block for conductively coupling at least one pair of electrical wires, the terminal block comprising:

• (a) a non-conductive base,
• (b) a first conductive bus bar mounted on the base,
• (c) a second conductive bus bar mounted on the base in a spaced apart relationship from the first bus bar,
• (d) a conductive shunt adapted to be disposed into selective common contact with both of the first and second bus bars, and
• (e) a non-conductive shuttle coupled to the conductive shunt, wherein the shuttle is capable of displacement relative to the shunt between a first position in which the shuttle insulates the shunt from both of the first and second bus bars and a second position in which the shuttle permits the shunt to conductively contact both of the first and second bus bars.

A terminal block for conductively coupling at least one pair of electrical wires, the terminal block comprising:

• (a) a non-conductive base,
• (b) a first conductive bus bar mounted on the base,
• (c) a second conductive bus bar mounted on the base in a spaced apart relationship from the first bus bar,
• (d) a conductive shunt adapted to be disposed into selective common contact with both of the first and second bus bars,
• (e) a spring chamber coupled to the base, and
• (f) at least one spring coupled at one of its ends to the spring chamber and at the other of its ends to the shunt.

A terminal block for conductively coupling at least one pair of electrical wires, said terminal block comprising:

• (a) a non-conductive base,
• (b) a conductive bus bar mounted on the base, the bus bar being shaped to define a threaded bore, and
• (c) a cover assembly mounted on the base over the conductive bus bar, the cover assembly comprising,
• (i) a non-conductive cover comprising a top surface, the cover being shaped to define a bore, and
• (ii) a captive screw assembly retained within the bore in the cover wherein, the captive screw assembly comprises,
• (a) a screw disposed within the bore in the cover, and
• (b) a spring disposed within the bore in the cover for resiliently urging the screw away from the bus bar and in the direction towards the top surface of the cover.

A terminal block for conductively coupling at least one pair of electrical wires, the terminal block comprising:

• (a) a non-conductive base,
• (b) a conductive bus bar mounted on the base,
• (c) an end cap mounted on the base, the end cap being adapted to be mounted on a DIN rail, the end cap having an outer end wall, and
• (d) a DIN rail lock disposed at a location inside of the outer end wall of the end cap, the DIN rail lock being adapted to selectively engage the DIN rail, wherein the DIN rail lock is coupled to at least one of the base and the end cap, wherein the DIN rail lock comprises:
• (i) a pin having a first end and a second end, and
• (ii) a bracket mounted on the second end of the pin, the bracket comprising at least one sharpened tooth.
