Abstract: A plug and socket type electrical connector is provided with a cover assembly for protecting connector structure from the elements and structure for facilitating the selective electrical engagement and disengagement of the connector elements, preferably by providing cooperating locking elements on the cover assembly and the electrical plug as well as a rotary lever assembly which is operable to effect plug disengagement.

Abstract: A coupling mechanism for coupling a plurality of fluid and electrical lines between adjacent coupled vehicles wherein a plurality of elongated flexible fluid lines and electrical lines are grouped together to form a single elongated flexible group line with one end of the group line connected to respective fluid and electrical sources on one vehicle and the other end of the group line connected to respective fluid and electrical loads on the other vehicle through a single hybrid or combination fluid and electrical plug and socket arrangement. The plug and socket arrangement is comprised of a mounting bracket for the plug and a mounting bracket for the socket, one of which is secured to the second vehicle. The mounting brackets are adapted such that one bracket is readily hung on the other bracket and thereby automatically prealigns the plug and socket for engagement.

Abstract: A gravity self-aligning article mount for suspension mounting of an article to a support wherein a first mounting bracket is adapted for securement to a support and a second mounting bracket is adapted for securement to an article to be suspended from the support. A vertically-extending horn is secured to upper portions of one of the brackets and an opening is provided in upper portions of the other of said bracket for receiving and seating the horn to hang the article bracket from the support bracket. The brackets have engaging body portions which underlie the aforedescribed horn and opening, and which body portions further respectively have mating convex and concave contoured seating surfaces adapted to gravitationally self-align one of the brackets with the other to vertical after the horn has been engaged in the opening.
