United States Patent Office 3,202,946 WAVE GUIDE CONNECTOR Donald J. Newman, Needham, Mass, assignor, by mesne assignments, to the United States of America as represented by the Secretary of the Army Filed Oct. 21, 1963, Ser. No. 317,852 1 Claim. (Cl. 3334-98) This invention relates to wave guide connectors and more particularly to a quick connect-disconnect wave guide connector.
Wave guides comprising more than one section require a connector between the adjoining sections. Standard wave guide connectors comprise a flange and a choke held in mated cont-act by a plurality of bolts or welds. The present invention comprises a wave guide connector wherein the choke is provided with threaded apertures and the flange is provided with slots matching the apertures of the choke. In this way bolts threadably held in the choke may be lefit in place and connection made by sliding the flange into mating contact with the choke and threadably tightening the bolts. One or more slots may be replaced by an aperture, as described below, to insure a secure connection.
It is therefore an object of the present invention to provide a wave guide connector that may be quickly and easily connected or disconnected.
It is a further object of the present invention to provide a wave guide connector which provides for reduction in wear on the threads of the connecting bolts upon repeated connections and disconnections of the wave guide sections, thereby allowing the flange and choke to mate more accurately and lengthen the bolt life.
These and other objects of the present invention will become more apparent from a consideration of the following description and drawings wherein:
FIGURE 1 shows an exploded view of the connector with three of the bolts in place in the choke; and
FIGURE 2 shows a perspective view of the connector in the connected position with all bolts in place.
A wave guide connector comprising a flange and a choke 12 is shown in FIGURE 1. Flange 10 comprises a generally rectangular plate 18 having parallel slots 29 disposed adjacent three of the four corners of the plate. A hole 22, for receiving a securing bolt 34, is disposed adjacent the fourth corner of plate 18. Choke 12 comprises a generally rectangular plate 24 having four threaded apertures 26 adjacent each of the tour corners of the plate and matched to slots 20 and hole 22 of plate 18. Plate 1 8 and plate 24 each carry a portion of the \wave guide 28 and 30, respectively, to be connected as shown in FIGURE 2, wherein the broad faces 14 and 16 are disposed in mated contact. Wave guide 28 is connected to wave guide 30 by slidalbly mating face 14 of plate .18 to face 16 of plate 24 and simultaneously engaging slots 20 in plate 18 with bolts 32 in plate 24. Bolts 32 are permanently engaged in .plate 24 and need only be threadably tightened to hold plate 18 in contact with plate 24. 'An additional bolt 34 is then inserted through hole 22 in plate 18 and threadably secured to plate 24 to insure a rigid connection between the two plates.
Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore understood that within the scope of the appended claim the invention may be practiced otherwise than was specifically described.
A connector for two highly conductive waveguide sections, each section having a central longitudinal axis: said connector including a first highly conductive end flange on one of said sections and a second highly conductive end flange. on the other section; a plurality of studs on said first flange, each stud being parallel to the section axis; a plurality of open ended slots in said second flange, said slots being equal in number to said studs, with all of the slots being parallel and transverse to the section axis; a threaded perforation in said first flange parallel to the section axis; a perforation in said second flange parallel to the section axis; and a threaded connector insert-able through the second perfioration and engaging said first perforation, upon traversing engagement of said slots and studs.
