Abstract

In connecting or making connections to multiple lines, it is important to prevent coupling intermix otherwise a dangerous fluid or a wrong or improper impressed voltage may be applied to the wrong line. The coupling illustrated may be applicable to either electrical or fluid (including gaseous) lines to inhibit improper connection of lines.

Keying Device for Quick Disconnect Coupling

In connecting or making connections to multiple lines, it is important to prevent coupling intermix otherwise a dangerous fluid or a wrong or improper impressed voltage may be applied to the wrong line. The coupling illustrated may be applicable to either electrical or fluid (including gaseous) lines to inhibit improper connection of lines.

In the drawing, a standard quick disconnect female coupling 10 is illustrated and it includes a modified outer body terminal end portion 11 with a pair of spaced axially extending slots 12 and 13. A standard quick disconnect male end 14 having a central projection 15 for coupling with the internal connection of the female end 10, includes a collar 16 which is connected by a set screw lock 17 to the male end 14.

The collar 16 includes a pair of spaced pins 18 and 19 which are adapted to register with the slots 12 and 13 on the female terminal end 11. Thus, each connector may be fitted with pins 18 and 19 which are adapted to mate with only a selectively spaced pair of slots 12 and 13. The pins act as the keyways for the connector, as well as insuring that there will be no intermix of either electrical or fluid carrying lines.
