Abstract
Abstract A method of adapting a miniature standard coaxial connector to enable the coupling of a fiber optic cable to an active device is disclosed in which the female portion of the connector is partially disassembled by removing its central contact and modified by drilling out or otherwise enlarging the passage which is left after the removal of the contact. The active device is mounted through a hole drilled in a printed circuit board, and electrically coupled to the top layer thereof. This unit is then affixed to the end of the female connector carrying the enlarged passage, such that the metalized layer on the printed circuit board makes electrical contact with the metal casing of the female portion of the connector, and such that the face of the active element is exposed through the enlarged passage.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
199 words
A method of modifying the female portion of a standard metal-bodied coaxial connector to accommodate an active electro-optical element adapted to be aligned with and coupled to a fiber optic element carried by the male portion of the connector, comprising the steps of: removing the central electrical contact; enlarging the hole left after removal; providing a printed circuit board with a metalized layer on one surface thereof; boring a hole through the printed circuit board of a size to accomodate the active electro-optical element; punching out a portion of the printed circuit board surrounding the hole bored therethrough; mounting an active element having laterally extending electrical contact tabs through the hole in the punched-out portion of the printed circuit board such that the tabs make electrical contact with the metalized layer; and, mounting the printed circuit board at the end of the female connector such that said element is adjacent the enlarged hole and such that electrical contact is made between the metalized layer on the printed circuit board and the housing of the female portion of the coaxial connector, whereby the modification does not require the mounting of the device inside the female portion 20 of the connector.
Claim 2
Independent Claim
199 words
A method of modifying the female portion of a standard metal-bodied coaxial connector to accommodate an active electro-optical element adapted to be aligned with and coupled to a fiber optic element carried by the male portion of the connector, comprising the steps of: removing the central electrical contact; enlarging the hole left after removal; providing a printed circuit board with a metalized layer on one surface thereof; boring a hole through the printed circuit board of a size to accomodate the active electro-optical element; punching out a portion of the printed circuit board surrounding the hole bored therethrough; mounting an active element having laterally extending electrical contact tabs through the hole in the punched-out portion of the printed circuit board such that the tabs make electrical contact with the metalized layer; and, mounting the printed circuit board at the end of the female connector such that said element is adjacent the enlarged hole and such that electrical contact is made between the metalized layer on the printed circuit board and the housing of the female portion of the coaxial connector, whereby the modification does not require the mounting of the device inside the female portion 20 of the connector.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein mounting the printed circuit board includes the step of using electrically conductive adhesive.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein mounting the printed circuit board includes the step of mechanically clamping said board to said housing.
Claim 5
Dependent Claim
45 words
The method of claim 3 wherein said clamping step includes the step of providing said housing with exterior screw threads and providing an apertured and interiorily threaded cap screwed on over the printed circuit board to sandwich the board between the cap and the housing.
Claim 6
Dependent Claim
25 words
The method of claim 1 and further including the step of providing said housing with electrical connection means prior to mounting the printed circuit board.
Claim 7
Independent Claim
118 words
A method of modifying the female portion of a standard coaxial connector to accommodate an active electro-optical element adapted to be aligned with and coupled to a fiber optic element carried by the male portion of the connector, comprising the steps of: removing the central electrical contact; enlarging the hole left after removal; providing a support; boring a hole through the support of a size to accommodate a portion of an active electro-optical element; mounting said active element through the hole in the support such that a portion thereof projects away from said support; and, mounting the support at the end of the female connector portion such that a portion of said element projects into the enlarged hole.
Claim 8
Independent Claim
118 words
A method of modifying the female portion of a standard coaxial connector to accommodate an active electro-optical element adapted to be aligned with and coupled to a fiber optic element carried by the male portion of the connector, comprising the steps of: removing the central electrical contact; enlarging the hole left after removal; providing a support; boring a hole through the support of a size to accommodate a portion of an active electro-optical element; mounting said active element through the hole in the support such that a portion thereof projects away from said support; and, mounting the support at the end of the female connector portion such that a portion of said element projects into the enlarged hole.
Claim 9
Independent Claim
169 words
A method of modifying the female portion of a standard metal-bodied coaxial connector to accommodate an active electro-optical element adapted to be aligned with and coupled to a fiber optic element carried by the male portion of the connector, comprising the steps of: removing the central electrical contact; enlarging the hole left after removal; providing a support with an electrically conducting layer on one surface thereof; boring a hole through the support of a size to accommodate a portion of an active electro-optical element; mounting an active element having laterally extending electrical contact tabs through the hole in the support such that the tabs make electrical contact with the electrically conducting layer and such that a portion of said element projects away from said support; and, mounting the support at the end of the female connector portion such that said element projects into the enlarged hole and such that electrical contact is made between the electrically conducting layer and the housing of the female portion of the coaxial connector.
Claim 10
Independent Claim
169 words
A method of modifying the female portion of a standard metal-bodied coaxial connector to accommodate an active electro-optical element adapted to be aligned with and coupled to a fiber optic element carried by the male portion of the connector, comprising the steps of: removing the central electrical contact; enlarging the hole left after removal; providing a support with an electrically conducting layer on one surface thereof; boring a hole through the support of a size to accommodate a portion of an active electro-optical element; mounting an active element having laterally extending electrical contact tabs through the hole in the support such that the tabs make electrical contact with the electrically conducting layer and such that a portion of said element projects away from said support; and, mounting the support at the end of the female connector portion such that said element projects into the enlarged hole and such that electrical contact is made between the electrically conducting layer and the housing of the female portion of the coaxial connector.
Claim 11
Dependent Claim
