1. An electrical connector comprising:
- a housing;
electrical contacts mounted to the housing; and
a coding module connected to the housing, the coding module comprising a frame and at least two keys, the frame being connected to the housing with a window for each key, the windows being orientated towards a path of insertion with a second connector, each key having a keying section located in one of the windows thereby blocking a portion of each window, the windows being larger than the keying sections such that a receiving area is provided in each window next to the keying sections, the keying sections being selectably positionable in the windows to provide a plurality of different blocked window patterns.

Abstract
Coding modules are connected to an electrical plug and an electrical socket to control whether or not the plug and socket can be connected to each other. Each module has a frame and two keys connected to their frames. The keys are selectively positionable on the frames to provide at least sixteen different key configurations for each module. The modules are snap-lock connected to the electrical plug and socket such that the module key configurations must be arranged in a complementary fashion before the plug and socket can be connected to each other.

10. An electrical connector coder comprising:
-
a frame having a key receiving area and means for connecting the frame to a first electrical connector; and a key having a mounting base and an off-center polarizing section, the key being positionable in the frame at a variety of orientations in the key receiving area such that the off-center polarizing section occupies a predetermined portion of the key receiving area, wherein the key and the key receiving area are adapted to prevent connection of the first electrical connector with a second electrical connector unless the key of the coder is cooperatingly matched to align with an adjacent portion of the second connector when the two connectors are mated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An electrical connector assembly comprising:
-
a first connector; a second connector adapted to be electrically and mechanically connected to the first connector; a first coder module connected to the first connector, the first coder module comprising a first frame and at least two first keys; and a second coder module connected to the second connector, the second coder module comprising a second frame and at least two second keys, the second frame having a window for each of the second keys, the second keys being located at least partially in the windows, the second keys being positionable at a variety of orientations in the windows to provide a variety of different blocked window configurations wherein the first and second connectors are prevented from being connected to each other unless the first keys are positioned to be located in the second coder module windows adjacent to the second keys. - View Dependent Claims (19, 20)
