Abstract: A support plate for an electrical connector shell mounted over an opening in the backplate of an avionics rack and panel tray to strengthen the connector shell from bending during insertion of and mating with a removable avionics electronics module. When an avionics module is inserted into the avionics tray, a great deal of force is applied to the connector shell tending to cause it to bend away from the force. This bending is substantially prevented by providing one or more support plates having a transverse plate aligned perpendicularly to the plane of the connector shell. The support plate is mounted on the rear side of the backplate by means of the same bolts used to mount the connector shell. The perpendicular transverse plate has a projection that extends through the opening in the backplate to abut against the rear face of the connector shell midway between its mountings, thereby resisting any rearward bowing or bending of the connector shell.

Abstract: Electrical devices which include electrical elements positioned within a container are assembled at the manufacturing site and then transported to the erection site by forming the container with openings therein such that transport supports can be inserted therethrough to contact the electrical elements. The transport supports may then be secured in place between the elements and the container walls. Upon erection into functioning position, the transport supports are removed and the openings covered with lids so that, if desired, the container can then be filled with gas.

Abstract: One or more radially projecting tabs are provided on a discontinuous ring for retaining the ring in proper association with a body member in spite of movement or vibration of the assembly. The tab, or tabs, mate with a grooved section of the body member. The groove may comprise a thread. The ring may be internal or external to the body member. The retaining tab will project radially outward or inward when the ring is to be internal or external, respectively, to the body member. The tabs have an axial thickness of the order of 25 percent, or less that of the ring. To provide secondary internal retaining means, a portion of the ring may be cut from an oversize ring so that a stress is formed when the ring is closed for inserting the ring in an internal opening. When a ring is to be used external to a body member, a simple cut may be made in an undersize ring so that a stress is formed when the ring is opened for placement external to the body member.
