Abstract
Abstract A novel high frequency electrical probe comprising: A blade-like active body member adapted to be supported at one end with its major plane at substantially 90° to a circuit to which contact is to be made; The other end of said body member formed to have a generally pointed edge to serve as a contact point to be abutted against the circuit; On both sides of said active body member, elements which are approximately coextensive with said body member, but having either no contact points, or pointed edges which abut said circuit at points slightly displaced from the contact point of said active body member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A novel high frequency electrical probe comprising: a blade-like active body member adapted to be supported at one end with its major plane at substantially 90° to a circuit to which contact is to be made; the other end of said body member formed to have a generally pointed edge to serve as a contact point to be abutted against the circuit; on both sides of said active body member, ground contacts which are approximately coextensive with said body member, but having pointed edges which abut said circuit at points slightly displaced from the contact point of said active body member.
Claim 2
Dependent Claim
101 words
A novel high frequency electrical probe comprising: a blade-like active body member adapted to be supported at one end with its major plane at substantially 90° to a circuit to which contact is to be made; the other end of said body member formed to have a generally pointed edge to serve as a contact point to be abutted against the circuit; on both sides of said active body member, ground contacts which are approximately coextensive with said body member, but having pointed edges which abut said circuit at points slightly displaced from the contact point of said active body member.
Claim 3
Dependent Claim
15 words
The novel high frequency probe of claim 1 wherein said probe has a uniform impedance.
Claim 4
Dependent Claim
54 words
The novel high frequency probe of claim 1 wherein the central regions of said blade-like member and ground contacts have areas of the member material removed forming said member into a double cantilever such that pressure of the pointed end against the circuit produces translation of said pointed end substantially 90° to the circuit.
Claim 5
Dependent Claim
34 words
The novel high frequency probe of claim 1 wherein the blade-like active body member is a thin layer of plastic carrying an electrical circuit in the form of a conductive metal deposit embedded therein.
Claim 6
Dependent Claim
42 words
The novel high frequency probe of claim 1 wherein said probe is carried on a mounting having an opening passing therethrough, and said contacts project through said opening into an underlying plane in which lays an exposed electrical circuit to be tested.
Claim 7
Dependent Claim
15 words
The novel high frequency probe of claim 1 wherein said ground contacts are beryllium copper.
Claim 8
Dependent Claim
141 words
A novel high frequency electrical probe comprising: a blade-like active body member having an electrically conductive region connected to a coaxial cable, adapted to be supported at one end with its major plane at substantially 90° to a circuit to which contact is to be made; the other end of said body member formed to have a generally pointed edge coinciding with an edge of said electrically conductive region to serve as a contact point to be abutted against the circuit; on both sides of said active body member, ground contacts which are approximately coextensive with said body member, but having pointed edges which abut said circuit at points slightly displaced from the contact point of said active body member; said active body member including a flared portion in said conductive region adjacent said coaxial cable to provide uniformity of impedance.
Claim 9
Dependent Claim
141 words
A novel high frequency electrical probe comprising: a blade-like active body member having an electrically conductive region connected to a coaxial cable, adapted to be supported at one end with its major plane at substantially 90° to a circuit to which contact is to be made; the other end of said body member formed to have a generally pointed edge coinciding with an edge of said electrically conductive region to serve as a contact point to be abutted against the circuit; on both sides of said active body member, ground contacts which are approximately coextensive with said body member, but having pointed edges which abut said circuit at points slightly displaced from the contact point of said active body member; said active body member including a flared portion in said conductive region adjacent said coaxial cable to provide uniformity of impedance.
