Abstract
Abstract A coaxial connector for use with signals haVing components of an appreciable frequency is disclosed which includes a forward connector plug structure having a pair of spring arms shaped relative to an underlying dielectric insert and a center conductor to provide impedance matching. The connector includes a structure which facilitates termination of shielded and coaxial cable and a method is disclosed for controlling the deformation of material of the connector to provide impedance matching relative to a circuit path of use.

In a method of terminating coaxial or shielded cable of the type having an inner conductor surrounded by a dielectric and an outer conductor and wherein such cable has a given characteristic impedance, which comprises the steps of: a. placing a stripped and prepared coaxial cable into a stamped and formed U-shaped connector; b. commencing to connect said connector to said coaxial cable by crimping said connector onto said cable; c. measuring the impedance of said connection during said crimping; and d. stopping said crimping when the impedance of said connection matches the given characteristic impedance of said coaxial cable.
Claim 2
Dependent Claim
100 words
In a method of terminating coaxial or shielded cable of the type having an inner conductor surrounded by a dielectric and an outer conductor and wherein such cable has a given characteristic impedance, which comprises the steps of: a. placing a stripped and prepared coaxial cable into a stamped and formed U-shaped connector; b. commencing to connect said connector to said coaxial cable by crimping said connector onto said cable; c. measuring the impedance of said connection during said crimping; and d. stopping said crimping when the impedance of said connection matches the given characteristic impedance of said coaxial cable.
Claim 3
Dependent Claim
48 words
The method of claim 1 including the step of injecting a signal through the connector in engagement with said cable and measuring the effect upon said signal in terms of the impedance of the circuit formed by said connector and said cable during deforMation of said connector portion.
Claim 4
Dependent Claim
47 words
The method of claim 1 wherein the step of measuring the impedance of said connection includes the step of injecting a signal into said connector device and the cable to which it is being terminated and measuring the signal components reflected by said termination to determine impedance.
Claim 5
Independent Claim
97 words

Claim 6
Independent Claim
97 words
The method of terminating coaxial cable to a connector which comprises the steps of: a. supplying a stamped and formed electrical connector of the type having a U-shaped outer conductive shell; b. laying a coaxial cable of a given impedance and of the type having an inner conductor surrounded by a dielectric and an outer conductor, into said electrical connector; c. crimping said electrical connector onto said coaxial cable causing a connection thereinbetween; d. measuring the impedance of said connection; and e. continuing said crimping until the impedance of said connection matches that of said coaxial cable.
Claim 7
Independent Claim
205 words
A method of connecting an electrical connector onto a coaxial cable of a given impedance and having an outer conductor, an inner conductor and a dielectric thereinbetween, which comprises the steps of: a. providing an electrical connector of the type having a U-shaped outer conductive shell, a center contact member having a opened U-shaped rear portion and a dielectric member positioned between said outer shell and said center member; b. preparing the coaxial cable whereby a end of the inner conductor is uncovered and a portion of the outer conductor is exposed; c. positioning said inner conductor of said coaxial cable into said U-shaped rear portion of said center contact member of said connector so that said exposed outer conductor of said coaxial cable is positioned into a portion of said U-shaped outer shell of said connector; d. causing a connection between said connector and said coaxial cable by crimping said U-shaped rear portion of said center contact member over said inner conductor and by crimping a portion of said U-shaped outer conductive shell over said exposed outer conductor and simultaneously measuring the impedance of said connection; and e. stopping said crimping when the impedance of the connection matches the impedance of said coaxial cable.
Claim 8
