Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
A coaxial high frequency switching device comprising: a housing; a plurality of female coaxial connectors adapted to receive male coaxial connectors mounted exteriorly of said housing in a single plane and each connector having a center lead supported by an insulator, the lead extending into said housing a short distance; a strip-line circuit board having a circuit pattern thereon including bonding pads at positions coinciding with the positions of said leads, said circuit board being mounted within said housing in the plane of said connectors at a level to effect an interference fit between said leads and said bonding pads, said leads being bonded to said pads; a relay secured to said board and having an armature directly contactable with selected porTions of said circuit pattern to effect desired switching; and insulated terminals in said housing connected to said relay.
Claim 2
Dependent Claim
140 words
A coaxial high frequency switching device comprising: a housing; a plurality of female coaxial connectors adapted to receive male coaxial connectors mounted exteriorly of said housing in a single plane and each connector having a center lead supported by an insulator, the lead extending into said housing a short distance; a strip-line circuit board having a circuit pattern thereon including bonding pads at positions coinciding with the positions of said leads, said circuit board being mounted within said housing in the plane of said connectors at a level to effect an interference fit between said leads and said bonding pads, said leads being bonded to said pads; a relay secured to said board and having an armature directly contactable with selected porTions of said circuit pattern to effect desired switching; and insulated terminals in said housing connected to said relay.
Claim 3
Dependent Claim
49 words
The switching device as claimed in claim 1, wherein said insulator surrounds and supports each said lead through the wall of said housing, and said leads are soldered to said pads along substantially the remainder of their length, whereby said leads are rigidly supported along substantially their entire length.
Claim 4
Dependent Claim
14 words
The switching device as claimed in claim 1, wherein said terminals include feed-through capacitors.
Claim 5
Dependent Claim
44 words
The switching device as claimed in claim 1, wherein said circuit board includes notches adjacent to and to one side of said bonding pads, whereby said board may be inserted over said leads in said housing and slid into interference fit with said leads.
Claim 6
Dependent Claim
33 words
The switching device as claimed in claim 1, wherein said circuit pattern comprises copper plated with nickel and hard gold, and each conductor therein is at least about one-eighth inch wide wherever possible.
Claim 7
Dependent Claim
57 words
The switching device as claimed in claim 1, wherein said housing comprises a rectangular body portion having said connectors mounted in walls thereof and said circuit board mounted on a raised bottom thereof, and a can portion bonded to the walls of said body portion around the periphery thereof, said can portion having said terminals passing therethrough.
Claim 8
Dependent Claim
21 words
The switching device as claimed in claim 3, wherein an inductor is connected between one of said capacitors and said relay.
Claim 9
Dependent Claim
26 words
The switching device as claimed in claim 4, wherein said relay is secured to said board with clamping means engageable in a pair of said notches.
Claim 10
Dependent Claim
130 words
In a coaxial high frequency switching device including a plurality of N-type coaxial connectors secured to a housing, insulated center leads extending thereinto, and relay means within said housing cooperating with circuitry for effecting desired switching between said leads, the improvements comprising: a strip-line circuit board having said circuitry on a surface thereof including bonding pads in interference fit with and soldered to said leads; an insulator securing each said lead within each connector and extending through the wall of said housing, each said lead being supported by said insulator or said bonding pad and solder along substantially its entire length; said relay being secured to said board and having an armature directly contactable with selected portions of said circuitry to effect desired switching upon energizing or deenergizing said relay.
Claim 11
Dependent Claim
