Quick Disconnect Waveguide Locking Mechanism

View page
US Patent:
4514708, Apr 30, 1985
Filed:
Feb 26, 1982
Appl. No.:
6/352629
Inventors:
Gerald W. Ludtke - Hoffman Estates IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01P 100
US Classification:
333255
Abstract:
The invention is a mechanism for holding a waveguide assembly and a down converter module in locked force multiplied engagement within a transceiver housing. The mechanism includes a lever arm which pivots about a first end which is secured to a bracket. The bracket in turn is secured to the transceiver housing. A knob which includes a locking structure is coupled to the second end of the lever arm. The locking structure is retained in a channel in the transceiver housing. The channel allows the locking structure to move within the channel between a first and second position. There is a camming surface on the lever arm that is more proximate to the first end of the lever arm than to the second end of the lever arm. An aligning pin is mounted on said first assembly in a location so as to engage the lever arm camming surface when the locking structure is physically moved along the transceiver housing channel from a first position to a second position. Movement of the locking structure from the first position to the second position causes the aligning pin to force the down converter module into a force multiplied engagement with the waveguide assembly.
