Patent ID: 7566234

Claim:
An electrical connector block arrangement for connecting a plurality of external conductors (C) with the circuits of a printed circuit board ( 3 ), comprising: (a) first connector block means ( 2 ) including: (1) a first generally rectangular stationary housing ( 27 ) formed from electrically-insulating synthetic plastic material, said first housing being adapted for mounting on the printed circuit board; (2) a row of first electrical contacts ( 7 ) carried by one side of said first housing; and (3) a plurality of conductive pins ( 8 ) operable to connect said first contacts with respective circuit of the printed circuit board; (b) second connector block means ( 1 ) arranged for displacement between separated and connected conditions relative to said first connector block means, said second connector block means including; (1) a second generally rectangular housing ( 15 ) formed from electrically-insulating synthetic plastic material; (2) a row of second electrical contacts ( 6 ) carried by one side of said second housing for respective engagement with said first contacts when said first and second connector housings are in said connected condition; and (3) electrically conductive jumper means ( 12 ) arranged in said second housing for normally electrically connecting together a group of said second contacts; and (c) code means ( 19 ) mounted on one of said housings for disconnecting at least one contact of said second contact group from said jumper means.
