Relay device, methods of assembling and mounting, and system

摘要

A relay device adapted to be removably mounted in plug-on circuit relation with a pair of male terminals. The relay device has a pair of separable housing members releasably secured to each other with a pair of female terminals disposed so as to be generally retained therewithin, and a pair of means is provided in each of the housing members for the passage of the male terminal pairs into electrical contacting engagement with the female terminal pair. A pair of means on one of the housing members is associated with the passage means pair thereof for holding engagement with at least one of the female terminal pair and the male terminal pair so as to prevent the displacement of the one housing member from the female terminal pair in the event of at least a partial separation of the housing member pair when the female terminal pair is in the electrical contacting engagement with the male terminal pair. A method of assembling a relay device and a method of mounting a relay device are also disclosed along with a system.
