The cylinder comprising an inside axial side wall spaced apart from an outside axial side wall joining top and bottom surfaces. The connector further comprises an axial channel open to the outside axial side wall intersecting the bottom surface and a housing open to the outside axial side wall. The housing being open to the top surface. An electrical transmission line connector is disposed within the housing. An electrical transmission line is disposed within the axial channel and connected within the housing to an adjacent electrical transmission device. The axial channel further comprises one or more tab closures. The tab closures may comprise a clamp. When fitted into the bore, the tabs close around a cable residing within the channel. ## Claims ### Claim 1 A tool string electrical transmission line connector assembly, comprising a cylinder adapted for mounting onto a shoulder within an axial bore wall of a tool string component; the cylinder comprising an inside axial side wall spaced apart from an outside axial side wall joining top and bottom surfaces; the outside axial side wall comprising an axial channel open to the outside axial side wall intersecting the bottom surface and intersecting a housing open to the outside axial side wall and open to the top surface, the axial channel comprising opposed axial outside edges at least partially protruding over the axial channel forming opposed tab closures, the respective axial protruding outside edges bend inward over the axial channel closing the axial channel when the cylinder is mounted within the axial bore, wherein an electrical transmission line connector is disposed within the housing, and wherein an electrical transmission line is disposed within the axial channel and connected within the housing to an adjacent electrical transmission device. ### Claim 2 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, further comprising the one or more opposing tab closures comprising a clamp protruding into the channel from an inside surface of the tab closures. ### Claim 3 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the cylinder is mounted within the bore using a press fit. ### Claim 4 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the cylinder comprises a slit cylinder mounted within the bore using a spring fit. ### Claim 5 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the bore comprises a tool joint. ### Claim 6 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the bore comprises a downhole tool within a bottom hole assembly. ### Claim 7 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the cylinder further comprises a modified outside axial side wall comprising discontinuities. ### Claim 8 (depends on 7) The tool string electrical transmission line connector assembly of claim 7, wherein the modified outside axial side wall comprising discontinuities is made up of diamond particles. ### Claim 9 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the outside axial side wall comprises a hardness greater than the hardness of the bore. ### Claim 10 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the outside axial side wall comprises a hardness less than the hardness of the bore. ### Claim 11 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the transmission device comprises an inductive coupler. ### Claim 12 (depends on 11) The tool string electrical transmission line connector assembly of claim 11, wherein the transmission device comprises an MCEI core disposed within a U-shaped annular open mesh housing. ### Claim 13 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the housing within the outside axial side wall comprises one or more tab closures. ### Claim 14 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the axial channel and housing comprise an electrical insulating filler. ### Claim 15 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the axial channel further comprises a gasket intersecting the bottom surface. ### Claim 16 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the housing comprises a gasket intersecting the top surface. ### Claim 17 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, wherein the top surface comprises an annular groove. ### Claim 18 (depends on 17) The tool string electrical transmission line connector assembly of claim 17, wherein an inductive coupler is disposed within the annular groove. ### Claim 19 (depends on 1) The tool string electrical transmission line connector assembly of claim 1, further comprising a transmission line clamp or anchor disposed within the housing.
