Locking pin

A high voltage electrical connector having separable male and female interconnects, the high voltage electrical connector comprising:

• a male interconnect comprising a substantially cylindrical contact pin having a first end, a mid-section, a second end and a locking groove;
• a female interconnect comprising a socket having a first end, a second end and a bore that extends inwardly from the second end and has a longitudinal axis, a passage extending transversely to the longitudinal axis and an opening connecting the bore to the passage, wherein the passage has an orifice;
• and
• a locking pin assembly having a cylindrical section and a concave section and comprising a shoulder bolt, a compression spring and a locking pin, wherein the shoulder bolt is coupled to the locking pin, and wherein the compression spring and the orifice are intermediate the shoulder bolt and the locking pin,
• wherein, when the concave section of the locking pin assembly is aligned with the opening, the contact pin can be inserted into and removed from the socket and wherein, when the contact pin is inserted in the socket and the locking groove is aligned with the opening, the cylindrical section of the locking pin assembly is aligned with the opening to lock the contact pin in the socket.

A high voltage electrical connector for connecting a cable to a bus bar, the connector comprising:

• a crimp barrel having a first end and a second end, wherein the first end is electrically coupled to one of the cable or bus bar and the second end has a tubular neck, wherein the tubular neck has an exterior surface, a first end and a second end connected to the first end of the crimp barrel;
• a collar having a threaded interior wall, wherein the collar is slidably and rotatably attached to the tubular neck;
• a contact pin having a first end and a second end, wherein the second end is in electrical engagement with the first end of the tubular neck;
• and
• a socket having a first end, a second end and a bore extending between the first end and the second end, wherein the first end is electrically coupled to the other of said cable or bus bar, and wherein the socket has an interior surface defined by the bore and the second end has a threaded exterior surface,
• wherein the connector is assembled by inserting the first end of the contact pin into the bore of the socket, sliding the threaded collar over the threaded exterior surface of the socket and rotating the collar to threadably couple the collar onto the second end of the socket.
