Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A D.C. block connector for microwave applications comprising an outer conductive shell, a pair of aligned inner conductors each formed with a flat inner end and mounted co-axially with the shell, an insulator between the shell and the inner conductors fixedly retained in the shell and formed with a longitudinal perforation into which the inner conductors are interference fitted and secured with their inner ends in facing relation, a ceramic capacitor smaller than the ends of the inner conductors, mounted in the perforation between the inner ends of the conductors and an axially compressible electrically conductive spring member loosely fitted in the perforation between the capacitor and the end surface of the adjacent inner conductor.
Claim 2
Dependent Claim
115 words
A D.C. block connector for microwave applications comprising an outer conductive shell, a pair of aligned inner conductors each formed with a flat inner end and mounted co-axially with the shell, an insulator between the shell and the inner conductors fixedly retained in the shell and formed with a longitudinal perforation into which the inner conductors are interference fitted and secured with their inner ends in facing relation, a ceramic capacitor smaller than the ends of the inner conductors, mounted in the perforation between the inner ends of the conductors and an axially compressible electrically conductive spring member loosely fitted in the perforation between the capacitor and the end surface of the adjacent inner conductor.
Claim 3
Dependent Claim
28 words
A connector according to claim 1 further characterized in that the members are dished and that each is positioned with its convex surface in contact with the capacitor.
Claim 4
Dependent Claim
25 words
A connector according to claim 2 further characterized in that each spring member is formed of beryllium copper and with a plurality of radial slots.
Claim 5
Dependent Claim
47 words
A connector according to claim 1 further characterized in that the outer shell is internally roughened, that the insulator is formed with exterior longitudinal splines and that a quantity of cement is inserted into the void defined by the interior roughening and the splines on the insulator.
Claim 6
Dependent Claim
29 words
A connector according to claim 4 further characterized in that the spring members are dished and that each is positioned with its convex surface in contact with the capacitor.
Claim 7
Dependent Claim
25 words
A connector according to claim 5 further characterized in that each spring member is formed of beryllium copper and with a plurality of radial slots.
Claim 8
Dependent Claim
31 words
A connector according to claim 1 further characterized in that each of the inner conductors is formed with an annular retaining barb and a splined end portion anchored in the insulator.
Claim 9
Dependent Claim
24 words
A connector according to claim 1 further comprising hermetic seals between the shell and the insulator and between the insulator and the inner conductors.
