- FIG. 1 -4 An exemplary embodiment of a laser weldable coaxial connector 2 is demonstrated in Figures 1 -4.
- a unitary connector body 4 is provided with a bore 6 dimensioned to receive the leading edge of the outer conductor 8 of a coaxial cable 9 therethrough.
- the leading edge of the outer conductor 8 extends through the bore 6 to a longitudinal position generally flush with the edge of a shoulder 10 of the connection interface 14 at the connector end 1 .1 1067

A portion of the dielectric material 26 may be provided extending forward of the leading edge of the outer conductor 8, for example as an interconnection impedance discontinuity reduction feature.

- the support ridges 34 reduce polymeric material requirements of the overbody 30 while providing lateral strength to the connector/interconnection 2 as well as alignment and retention of the coupling nut 36. 1 .1 1067

- the outer jacket 28 and and/or the inner diameter of the overbody 30 may be provided as a series of spaced apart annular peaks of a contour pattern such as a corrugation 46, as shown for example in Figure 12, or a stepped surface 48, as shown for example in Figure 13.
- the overbody 30 may be sealed against the outer jacket 28 with an adhesive/sealant or may be overmolded upon the connector body 4 after interconnection with the outer conductor 8, the heat of the injected polymeric material bonding the overbody 30 with and/or sealing against the outer jacket 28.

- the socket geometry of the center cap 50 and or the end of the inner conductor 24 may be formed to provide annular material gaps 22.
- Laser welding apparatus may be provided with a fiber optic laser head extension which may be adjusted to aim the laser beam B at each target location along the seam 16.
- the coaxial connector 2 upon which the target location resides, may be maneuvered to align the target location with respect to the laser head 54.
- a laser head 54 typically includes a collimator 56 and a focus lens 58 which focuses the laser beam B upon a focal point F at the target location.
- the laser beam B extent has clearance requirements prior to reaching the focal point F which are satisfied by the connector end 18 facing orientation of the seam 16 in the exemplary
- the laser beam B Prior to and once beyond the focal point F, the laser beam B has an increasing diameter, progressively diminishing the effective power of the beam at longitudinal locations other than the focal point F.
- the laser head 54 may be positioned with respect to the seam 16, such that the focal point F is below the seam 16 outer face, for example as shown in Figure 16. Thereby, the highest power level is obtained as a molten area of the bore sidewall 20 and the outer 1 .1 1067 diameter of the outer conductor 8 is formed within the seam 16, rather than only along the outermost surface of the seam 16, resulting in a weld with greater depth and strength.
- the bore 6 may be provided with an inward projecting stop shoulder 52 proximate the connector end 18 against which the outer conductor 8 abuts to form an inward facing circumferential seam 16 between the outer conductor 8 and the stop shoulder 52.
- the seam 16 is provided generally normal to a longitudinal axis of the coaxial connector 2.
- the ability of the laser beam B to reach the seam 16 without interference from the inner conductor 24 is a function of the coaxial cable dimensions and the distance from the connection interface 14 within the bore 6 at which the seam 16 is located.
- the present embodiment also requires removal of additional dielectric material 26, which may generate impedance discontinuity issues addressable by the addition of further impedance tuning features, such as dielectric spacers or the like.

Abstract
A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by laser welding is provided with a monolithic connector body with a bore. A sidewall of the bore is provided with an inward annular projection angled toward a cable end of the bore. A sidewall of the inward annular projection and the sidewall of the bore form an annular laser groove open to a cable end of the bore. The annular laser groove is dimensioned with a taper at a connector end of the laser groove less than a thickness of a leading end of the outer conductor. The taper provides an annular material chamber between the leading end of the outer conductor, when seated in the laser groove, and the connector end of the laser groove.
Description
Laser Weld Coaxial Connector and Interconnection Method
BACKGROUND
Field of the Invention
This invention relates to electrical cable connectors. More particularly, the invention relates to a coaxial cable connector interconnectable via laser welding.
Description of Related Art
Coaxial cable connectors are used, for example, in communication systems requiring a high level of precision and reliability.
To create a secure mechanical and optimized electrical interconnection between the cable and the connector, it is desirable to have generally uniform, circumferential contact between a leading edge of the coaxial cable outer conductor and the connector body. A flared end of the outer conductor may be clamped against an annular wedge surface of the connector body via a coupling body. Representative of this technology is commonly owned US Patent No. 6793529 issued September 21 , 2004 to Buenz.
Although this type of connector is typically removable/re-useable, manufacturing and installation is complicated by the multiple separate internal elements required, interconnecting threads and related environmental seals.
Connectors configured for permanent interconnection via solder and/or adhesive interconnection are also well known in the art. Representative of this technology is commonly owned US Patent No. 5802710 issued September 8, 1998 to Bufanda et al.
1 .1 1067
However, solder and/or adhesive interconnections may be difficult to apply with high levels of quality control, resulting in interconnections that may be less than satisfactory, for example when exposed to vibration and/or corrosion over time.
Competition in the coaxial cable connector market has focused attention on improving electrical performance and long term reliability of the cable to connector interconnection. Further, reduction of overall costs, including materials, training and installation costs, is a significant factor for commercial success.

Detailed Description
Aluminum has been applied as a cost-effective alternative to copper for the conductors in coaxial cables. However, aluminum oxide surface coatings quickly form upon air- exposed aluminum surfaces. These aluminum oxide surface coatings may degrade traditional mechanical, solder and/or conductive adhesive interconnections.
The inventors have recognized that increasing acceptance of coaxial cable with solid outer conductors of aluminum and/or aluminum alloy enables connectors configured for interconnection via laser welding between the outer conductor and a connector body which may also be cost effectively provided, for example, formed from aluminum and/or aluminum alloy.
An exemplary embodiment of a laser weldable coaxial connector 2 is demonstrated in Figures 1 -4. As best shown in Figure 4, a unitary connector body 4 is provided with a bore 6 dimensioned to receive the leading edge of the outer conductor 8 of a coaxial cable 9 therethrough. Positioned for interconnection by laser welding, the leading edge of the outer conductor 8 extends through the bore 6 to a longitudinal position generally flush with the edge of a shoulder 10 of the connection interface 14 at the connector end
1 .1 1067
18, presenting a common end face to the connector end 18, as best shown in Figure 5. The connection interface 14 may be any desired standard or proprietary connection interface 14 which includes access to a circumferential contact seam 16 between the bore 6 and the outer conductor 8, the seam 16 generally parallel to a longitudinal axis of the coaxial connector 2.
One skilled in the art will appreciate that connector end 18 and cable end 12 are applied herein as identifiers for respective ends of both the coaxial connector 2 and also of discrete elements of the coaxial connector 2 described herein, to identify the same and their respective interconnecting surfaces according to their alignment along a
longitudinal axis of the coaxial connector 2 between a connector end 18 and a cable end 12.
Where the diameter of the bore 6 is selected with respect to the diameter of the outer conductor 8 to be a close tolerance fit, laser welding interconnection of the outer conductor 8 and the connector body 2 may be performed without the addition of further material, such as welding rod or wire. The high level of localized heating from the laser, applied to the seam 16 between the outer conductor 8 and the connector body 2, may be applied as a pulse directed to a target spot, with successive pulses applied to an overlapping spot portion to form a continuous weld between adjacent portions of the outer conductor 8 and the connector body 2.
1 .1 1067
Prior to interconnection via laser welding, the end of the cable 9 may be prepared, as best shown in Figure 6, by cutting the cable 9 so that the inner conductor 24 extends from the outer conductor 8. Also, dielectric material 26 between the inner conductor 24 and outer conductor 8 may be stripped back and a length of the outer jacket 28 removed to expose desired lengths of each. A portion of the dielectric material 26 may be provided extending forward of the leading edge of the outer conductor 8, for example as an interconnection impedance discontinuity reduction feature.
Where applicable, the cable end preparation may also include the step of straightening the cable end portion, for example to eliminate any bending in the cable resulting from bulk cable delivery of the cable wound in spools, so that when inserted into the bore 6, the cable end is coaxial with the bore 6 along its length and the inner conductor 24 projects from the connector end 18 parallel to the longitudinal axis of the bore 6.
Thereby, the seam between the bore sidewall 20 and the outer diameter of the outer conductor 8 will be uniform around the circumference of the outer conductor 8, increasing the uniformity of the resulting laser weld.
Because the localized heat of the laser welding process can disrupt aluminum oxide surface coatings in the immediate weld area, no additional care may be required with respect to removing or otherwise managing the presence of aluminum oxide on the interconnection surfaces.
1 .1 1067
An overbody 30, as shown for example in Figure 10, may be applied to the connector body 4 as an overmolding of polymeric material. The overbody 30 increases cable to connector torsion and pull resistance. The overbody 30 may also provide connection interface structure at the connector end 18 and further reinforcing support at the cable end 12, enabling significant reductions in the size of the connector body 4, thereby reducing overall material costs.
Depending upon the applied connection interface 14, demonstrated in the exemplary embodiments herein as a standard 7/16 DIN interface, the overbody 30 may be provided with an overbody flange 32 and longitudinal support ridges 34 for a coupling nut 36. The coupling nut 36 is retained upon the support ridges 34 at the connector end 18 by an overbody flange 32 and at the cable end 12 by a retention spur 38 provided on at least one of the support ridges 34. The retention spur 38 may be angled toward the connector end 18, allowing the coupling nut 36 to be placed over the cable 9 initially spaced away from the coaxial connector 2 during interconnection (see Figure 1 ), but then allowing the coupling nut 36 to be passed over the retention spur 38 and onto the support ridges 34 from the cable end 12, to be thereafter retained upon the support ridges 34 by the retention spur(s) 38 (see Figure 2) in close proximity to the connector interface 14 for connector to connector mating. The support ridges 34 reduce polymeric material requirements of the overbody 30 while providing lateral strength to the connector/interconnection 2 as well as alignment and retention of the coupling nut 36.
1 .1 1067
The overbody 30 may also extend from the connector end 18 of the connector body 4 to provide portions of the selected connection interface 14, such as an alignment cylinder 39 of the 7/16 DIN interface, further reducing metal material requirements of the connector body 4.
The overbody flange 32 may be securely keyed to a connector body flange 40 of the connector body 4 and thereby with the connector body 4 via one or more interlock apertures 42 such as holes, longitudinal knurls 43, grooves, notches 45 or the like provided in the connector body flange 40 and/or outer diameter of the connector body 4, as demonstrated in Figures 7-9. Thereby, as the polymeric material of the overbody 30 flows into the interlock apertures 42 during overmolding, upon curing the overbody 30, for example as shown in Figure 10, is permanently coupled to and rotationally
interlocked with the connector body 4.
As best shown in Figure 1 1 , the cable end 12 of the overbody 30 may be dimensioned with an inner diameter friction surface 44 proximate that of the coaxial cable outer jacket 28, enabling polymeric friction welding between the overbody 30 and the outer jacket 28 prior to laser welding of the connector body 4 and outer conductor, thereby eliminating the need for environmental seals at the cable end 12 of the connector/cable
interconnection. During friction welding, the coaxial connector 2 is rotated with respect to the cable 9. Friction between the friction surface 44 and the outer diameter of the outer jacket 28 heats the respective surfaces to a point where they begin to soften and intermingle, sealing them against one another. To provide enhanced friction and allow
1 .1 1067 voids for excess flow due to friction displacement and add key locking for additional strength, the outer jacket 28 and and/or the inner diameter of the overbody 30 may be provided as a series of spaced apart annular peaks of a contour pattern such as a corrugation 46, as shown for example in Figure 12, or a stepped surface 48, as shown for example in Figure 13. Alternatively, the overbody 30 may be sealed against the outer jacket 28 with an adhesive/sealant or may be overmolded upon the connector body 4 after interconnection with the outer conductor 8, the heat of the injected polymeric material bonding the overbody 30 with and/or sealing against the outer jacket 28.
The inner conductor 24 extending from the prepared end of the coaxial cable 9 may be selected to pass through to the connector end 18 as a portion of the selected
connection interface 14, for example as shown in Figure 8. If the selected coaxial cable 9 has an inner conductor 24 that has a larger diameter than the inner conductor portion of the selected connection interface 14, the inner conductor 24 may be ground at the connector end 18 to the required diameter.
Although a direct pass through inner conductor 24 advantageously eliminates interconnections, for example with the spring basket of a traditional coaxial connector inner contact, such may introduce electrical performance degradation such as PIM. Where the inner conductor 24 is also aluminum material some applications may require a non-aluminum material connection point at the inner contact/inner conductor of the connection interface 14. As shown for example in Figure 14, a center cap 50, for
1 .1 1067 example formed from a metal such as brass or other desired metal, may be applied to the end of the inner conductor 24, also by laser or friction welding. To apply the center cap 50, the end of the inner conductor 24 is ground to provide a pin corresponding to the selected socket geometry of the center cap 50. To allow material inter-flow during welding attachment, the socket geometry of the center cap 50 and or the end of the inner conductor 24 may be formed to provide annular material gaps 22.
Laser welding apparatus may be provided with a fiber optic laser head extension which may be adjusted to aim the laser beam B at each target location along the seam 16. Alternatively, the coaxial connector 2, upon which the target location resides, may be maneuvered to align the target location with respect to the laser head 54. A laser head 54 typically includes a collimator 56 and a focus lens 58 which focuses the laser beam B upon a focal point F at the target location. As shown in Figure 15, the laser beam B extent has clearance requirements prior to reaching the focal point F which are satisfied by the connector end 18 facing orientation of the seam 16 in the exemplary
embodiment.
Prior to and once beyond the focal point F, the laser beam B has an increasing diameter, progressively diminishing the effective power of the beam at longitudinal locations other than the focal point F. To maximize heat generation for welding, the laser head 54 may be positioned with respect to the seam 16, such that the focal point F is below the seam 16 outer face, for example as shown in Figure 16. Thereby, the highest power level is obtained as a molten area of the bore sidewall 20 and the outer
1 .1 1067 diameter of the outer conductor 8 is formed within the seam 16, rather than only along the outermost surface of the seam 16, resulting in a weld with greater depth and strength.
In further embodiments, for example as shown in Figures 17 and 18, the bore 6 may be provided with an inward projecting stop shoulder 52 proximate the connector end 18 against which the outer conductor 8 abuts to form an inward facing circumferential seam 16 between the outer conductor 8 and the stop shoulder 52. The seam 16 is provided generally normal to a longitudinal axis of the coaxial connector 2. As shown in Figures 19 and 20, the ability of the laser beam B to reach the seam 16 without interference from the inner conductor 24 is a function of the coaxial cable dimensions and the distance from the connection interface 14 within the bore 6 at which the seam 16 is located.
In addition to increased adjustment requirements for the laser beam to follow the inner circumference of the seam 16, the present embodiment also requires removal of additional dielectric material 26, which may generate impedance discontinuity issues addressable by the addition of further impedance tuning features, such as dielectric spacers or the like.
One skilled in the art will appreciate that the connector and interconnection method disclosed has significant material cost efficiencies and provides a permanently sealed interconnection with reduced size and/or weight requirements.
