(17) FIG. 2 is a bottom perspective view of the RF compression connector 10 shown in FIG. 1. The second conductor end 24 of the first conductor 18 and a fourth conductor end 28 of the second conductor 20 can each terminate at the recessed area 38 of the housing 12, between the compression mounts 32, and under the mating block 34. The second conductor end 24 and the fourth conductor end 28 can both be compression mounted to a mounting substrate (not shown). The second conductor end 24, the fourth conductor end 28, or both can be butt-coupled to a corresponding, respective pad on the mounting substrate. Each pad can include a point on the mounting substrate coincident with an arc, circle, or curve of the mounting substrate such that at least two or at least three consecutive trace lengths that extent from the center of each respective pad to are equal in physical length, electrical length, or both physical length and electrical length.

The first recess 42 and the second recess 44 can each be closed-ended adjacent to the third wall 40B of the mating block 34 or not extend all the way to an external surface of the third wall 40B of the mating block 34. The first conductor end 22 and the fourth conductor end 28 can both terminate in the recessed area 38, the first recess 42, or the second recess 44, and can both not terminate outside of the recessed area 38. The first conductor end 22 and the fourth conductor end 28 can both butt-couple terminate to a corresponding pad or trace on a mounting substrate (not shown).
(18) FIG. 3 is cross-sectional view of the RF compression connector 10 of FIGS. 1 and 2. The first conductor 18 and second conductor 20 can both be electrically insulated from the housing 12. Housing 12 can define one or more compression mounts 32. Each respective opening OP, OP1 can define a first opening 46 that has a first radius R1, circumference, or area and a second opening 48 that has a second radius R2, circumference, or area. A first radius R1, circumference, or area of the first opening 46 is greater than a second radius R2, circumference, or area of the second opening 48. Respective first insulator 14 and second insulator 16 may each be positioned adjacent to a corresponding second opening 48 of each respective port 30, 30A. In FIG. 3, for clarity, the first insulator 14 and the second insulator 16 are shown as see through, but the first insulator 14 and the second insulator 16 can be opaque and do not have to be transparent. First conductor 18 and second conductor 20 may each have a respective first conductor width W4 inside a respective one of the first insulator 14 or the second insulator 16. First conductor 18 and second conductor 20 may each have a respective second conductor width W5 outside of a respective one of the first insulator 14 or the second insulator 16, where the second conductor width W5 is greater in length than the first conductor width W4. An overall width OW of the housing 12, along the longitudinal direction L, is preferably smaller in width than two single-port, compression, vertical RF connectors each positioned end-to-end along a common line. Housing 12 can have a first footprint area that is smaller than a second combined footprint area of two single-port, compression, vertical RF compression connectors.
(19) First conductor 18, second conductor 20, second conductor end 24, and fourth conductor end 28 can each be spaced from a respective first internal wall 50 or second internal wall 52 of the housing 12 and separated from the housing 12 by an air gap AG or other electrical insulator. The first conductor end 22 of the first conductor 18 and the third conductor end 26 of the second conductor 20 can each extend into a respective opening OP, OP1. The first conductor end 22 of the first conductor 18 and the third conductor end 26 of the second conductor 20 can each extend into a respective second opening 48 of a respective port 30, 30A. Alternatively, respective first and third conductor ends 22, 26 can each extend into both the first and second openings 46, 48 defined by the housing 12 or the mating block 34 of the housing 12.
(20) FIG. 4 shows an RF compression connector 10A of a second embodiment of the present invention. The housing 12A of the RF compression connector 10A is similar to the housing 12 shown in FIGS. 1-3, and other components shown in FIGS. 1-4 are also similar. However, a recessed area 38A of the housing 12A shown in FIG. 4 is structurally different from the recessed area 38 of the housing 12 shown in FIGS. 1-3. More specifically, FIG. 4 shows that a first recess 42A can be divided into a distinct first channel 54 and a distinct second channel 56. The first channel 54 and the second channel 56 can diverge at respective first ends 58 and can converge at respective second ends 60. The first channel 54 and the second channel 56 can both be spaced apart from one another.
(21) The RF compression connectors can include at least two or at least three consecutive conductors. If the RF compression connectors includes at least three consecutive conductors, each of the at least three consecutive conductors can lie coincident with a respective point or pad that lies on or is intersected by on a common arc, radiused curve, or portion of a circle. Alternatively, respective ends of the conductors of the RF compression connectors can be arranged along on a common arc, radiused curve, or portion of a circle, such as a circular arc with a constant radius of curvature.
(22) FIG. 5 shows multi-port, vertical, compression or surface-mounted RF connectors 62, 62A, 62B mounted to a substrate 74, such as a test board, printed circuit board, substrate, etc., according to third, fourth, and fifth embodiments of the present invention. The RF connectors 62, 62A, 6B can be similar to the RF compression connectors 10, 10A shown in FIGS. 1-4, and can use similar materials and similar constructions. There are, however, at least two differences between the RF compression connectors 10, 10A of FIGS. 1-4 and the RF connectors 62, 62A, 62B of FIG. 5. One difference is that housing 64 can define at least one or at least two curved or radiused housing side walls 70. Another difference is that port centers C11-C16, C17-C20, and C21-C22 of respective ports 72, 72A, 72B each lie coincident with corresponding points of an arc, a curve, or a portion of a circumference of a circle. An arc, curve, or portion of a circumference of a circle can have a constant radius. The port centers C11-C16, C17-C20, and C21-C22 of respective ports 72, 72A, 72B can be arranged along an arc, such as, for example, a circular arc with a constant radius of curvature. Because the port centers C11-C16, C17-C20, and C21-C22 can be arranged along an arc, the conductors (or the ends of the conductors) within the port centers C11-C16, C17-C20, and C21-C22 can be arranged along the arc.
(23) The respective housings 64, 64A, 64B shown in FIG. 5 can be rectangular in shape, can include an arc or a portion of a circle, or can include other shapes. For example, housing 64 has two opposed housing side walls 70 that are each curved or define an arc or a portion of a circumference of a circle. As shown in FIG. 5, one of the opposed housing side walls 70 follows a first pre-defined radius from a center C, and the other opposed housing side wall 70 follows a second pre-defined radius from the center C that is less than the first pre-defined radius. Housings 64A and 64B can each define a rectangular shape but can each have one or two opposed housing walls 70A, 70B that define a curved shape. The housing 64A includes port centers C17-C20 that are arranged along an arc, such as circular arc with a constant radius of curvature, and housing walls 70A that are straight. That is, the port centers C17-C20 in housing 64A are arranged along a shape (e.g., arc) that is not similar to the shape (e.g., straight line) defined by the walls 70A of the housing.
(24) The embodiments shown in FIG. 5 are designed such that all respective port centers C11-C16 of RF connector 62, all respective port centers C17-C20 of RF connector 62A, or all respective port centers C21, C22 of RF connector 62B are all spaced from center C by equal or substantially equal within manufacturing and/or measurement tolerances radii R3.
(25) RF connectors 62, 62A, 62B shown in FIG. 5 can each include a respective housing 64, 64A, 64B. Each respective housing 64, 64A, 64B can include a mating end 66, 66A, 66B, an opposed mounting end 68, 68A, 68B, and two opposed housing side walls 70, 70A, 70B. The mating end 66, 66A, 66B can define a mating interface to which a corresponding connector can be mated, and the mounting end 68, 68A, and 68B can define a mounting interface that can be mounted to a suitable substrate, e.g., test substrate, PCB, etc. At least two or at least three consecutive ports 72, 72A, 72B can be defined by a respective housing 64, 64A, 64B. Respective first conductors, similar to the first conductors 18 shown in FIGS. 1-4, can be respectively positioned in a first port of the at least three consecutive ports 72, 72A, 72B shown in FIG. 5, coincident with a respective port center C11, C17, C21. Respective second conductors, similar to the second conductors 20 shown in FIGS. 1-4, can be respectively positioned in a second port of the at least three consecutive ports 72, 72A, 72B shown in FIG. 5, coincident with a respective port center C12, C18, C21. Respective third conductors, similar to the first or second conductors 18, 20 shown in FIGS. 1-4, can be respectively positioned in a third port of the at least three consecutive ports 72, 72A, 72B shown in FIG. 5, coincident with a respective port center C13, C19. Each of the at least three consecutive ports 72, 72A, 72B can have a respective port center C11, C12, C13, C17, C18, C19 that lies coincident with a respective point coincident with or on a arc A1. The arc A1 can be circular arc, i.e., an arc with a constant radius of curvature. The port center C11, C12, C13, C17, C18, C19 can be arranged along an arc, such as, for example, a circular arc with a constant radius of curvature. Stated another way, each housing 64, 64A, 64B has respective port centers C11-C16, C17-C20, C21-C22 that each lie the same radial or linear distance from the center C. The respective port centers C11-C13, C17-C19, C21-C22 of at least two or at least three consecutive ports 72, 72A, 72B can each define a portion of an arc or a portion of a circumference of a circle within the confines of a respective housing 64, 64A, 64B. The at least three consecutive ports 72, 72A, 72B can include, for example, at least four consecutive ports, at least five consecutive ports, at least six consecutive ports, at least seven consecutive ports, at least eight consecutive ports, at least nine consecutive ports, or at least ten consecutive ports.
(26) Each housing 64, 64A, 64B shown in FIG. 5 can be a single-piece housing. Each housing 64, 64A, 64B can be a vertical housing. Each respective port center C11, C12, C13, C17, C18, C19 of the at least three consecutive ports 72, 72A, 72B are preferably not connected by a single straight line. Each respective port center C11-C13, C17-C19 of the at least three consecutive ports 72, 72A, 72B can preferably be connected only by a non-linear line. Each respective port center C11-C13, C17-C19 of the at least three consecutive ports 72, 72A, 72B can preferably be connected only by a curved line. Each respective port center C11-C13, C17-C19 of the at least three consecutive ports 72, 72A, 72B can preferably be connected only by a curved line having a fixed radius R3.
(27) The fixed radii R3 are only used to show the geometry of how the various ports C11-C22 can be arranged along a common arc, a portion of a circle, etc. The fixed radii R3 can only approximate corresponding signal traces, however, because signal traces cannot all electrically terminate at a common point or common center C (for example, causing electrical shorting). For signal trace routing, a first electrical signal path length can be measured between an intersection of a corresponding second conductor end 24 (shown in FIG. 3) and a corresponding first pad or first signal trace positioned at least partially under a corresponding, respective port 72, 72A, 72B, and an opposite first end of the first signal trace that is configured to be attached to a first connector conductor of another connector in the general vicinity of center C or an edge of substrate 74. A second electrical signal path length can be measured between an intersection of a corresponding fourth conductor end 28 shown in (FIG. 3) and a corresponding second pad or second signal trace positioned at least partially under a corresponding, respective port 72, 72A, 72B, and an opposite second end of the second signal trace that is configured to be attached to a second conductor connector of the another connector, also in the general vicinity of center C or the edge of substrate 74. A third electrical signal path length can be measured between an intersection of a corresponding sixth conductor end (not shown) and a corresponding third pad or third signal trace positioned at least partially under a corresponding, respective port 72, 72A, 72B, and an opposite third end of the third signal trace that is configured to be attached to a third connector conductor of the another connector, also in the general vicinity of center C or the edge of substrate 74. The first and second electrical signal path lengths can be immediately adjacent to one another. The first, second, and third electrical signal path lengths can each be consecutive, that is, with no electrical signal paths between the first and second electrical signal path lengths and no electrical signal paths between the second and third electrical signal path lengths. The first electrical path length can be physically equal, electrically equal, or both physically equal and electrically equal to the second electrical path length, the third electrical path length, or both the second and third electrical path lengths.
(28) Respective housings 64, 64A, 64B shown in FIG. 5 can be single-piece, monolithic, or unitary, and can be compression mounted to the substrate 74 or surface mounted to the substrate 74. The first conductor of the RF connectors 62, 62A, 62B shown in FIG. 5 can be a vertical conductor, and the second conductor of the RF connectors 62, 62A, 62B shown in FIG. 5 can be a vertical conductor, similar to the first and second conductors 18, 20 shown in FIGS. 1-4.
(29) A method can include a step of providing an RF connector with at least two or at least three consecutive conductors, wherein each of the at least two or at least three consecutive conductors lies coincident with a point on a common arc, radiused curve, or portion of a circle. The conductors of the RF connector can be arranged along an arc, such as, for example, a circular arc with a constant radius of curvature. The method can include another step of mounting the RF connector onto a substrate that has at least two or at least three consecutive traces that each have the same electrical lengths, the same physical lengths, or both the same electrical lengths and the same physical lengths. The method can further include as step of varying a centerline spacing between at least three sequential electrical conductors such that each of the at least three sequential electrical conductors each has a respective center that lies coincident with or on a corresponding respective point on an arc, curve, or portion of a circle with a fixed or constant radius. The at least three sequential electrical conductors be arranged along an arc the at least three sequential electrical conductors.
(30) FIGS. 6-9 show a cable assembly 76 that can include a first cable connector 78 at a first cable assembly end 80, a second cable connector 80 at a second cable connector end 84, a third cable connector 82 at the second cable assembly end 84, first and second cables 86, 86A, and one or more strain reliefs 88.
(31) The first cable 86 and the second cable 86A can each be coaxial cables or RF cables. Coaxial cables and RF cables each typically define a circular cross-section. A center of one or both of the first and second cables 86, 86A can include a respective electrically conductive cable conductor that extends along a cable conductor length. An electrically non-conductive cable insulator can encircle the cable conductor along its cable conductor length, and an electrically conductive cable shield can encircle the cable insulator along the cable conductor length. An electrically non-conductive jacket, for example, a PVC jacket, can encircle the electrically conductive cable shield. Alternatively, the first and second cables 86, 86A can be a single twin axial cable having two electrically conductive cable conductors, with one of the two cable conductors extending between the first cable connector 78 and the second cable connector 80. The other one of the two cable conductors can extend between the first cable connector 78 and the third cable connector 82.
(32) As shown in FIGS. 6 and 7, a first cable conductor (not shown) of first cable 86 can be electrically, physically, or both electrically and physically connected to a first cable connector conductor 90. A second cable conductor (not shown) of second cable 86A can be electrically, physically, or both electrically and physically connected to another first cable connector conductor 92. A first cable ground shield (not shown) of first cable 86 can be electrically, physically, or both electrically and physically connected to a first cable ground conductor 94. A second cable ground shield (not shown) of second cable 86A can be electrically, physically, or both electrically and physically connected to a second cable ground conductor 96. Within a single-piece, first cable connector housing 98 of the first cable connector 78, the first cable connector conductor 90 and the another first cable connector conductor 92 can each be electrically insulated from one another. The first cable connector conductor 90 and the another first cable connector conductor 92 can both be electrically insulated from a respective one of the first and second cable ground conductors 94, 96, for example, by respective electrically insulative spacer 116.
(33) As shown in FIG. 7, the first cable connector 78 can be a dual-port first cable connector 78, configured to mate with a corresponding dual-port RF connector, for example, the RF compression connectors 10, 10A shown in FIGS. 1-4 or the RF connectors 62, 62A, 62B shown in FIG. 5. Each of the first cable connector conductors 90 and the another first cable connector conductor 92 can be shaped the same or can be shaped differently. In order to successfully mate with the dual-port RF connectors discussed above, each of the first cable connector conductors 90 and the another first cable connector conductor 92 can define a receptacle configured to receive a respective conductor, for example, the first or second conductor 18, 20 described with respect to FIGS. 1-5. Alternatively, one or both of the first cable connector conductor 90 and the another first cable connector conductor 92 can be pins that receive a respective receptacle conductor, for example, similar to the first or second conductor 18, 20 described with respect to FIGS. 1-5.
(34) One or more first cable connector conductor 90 and one or more another first cable connector conductor 92 can define a solid pin, a machined receptacle, or a receptacle defined by two or more first and second conductor arms 100, 100A, as shown in FIG. 7. One or more first cable ground conductor 94 and one or more second cable ground conductor 96 can define a solid pin, a machined receptacle, or a receptacle defined by two or more first and second ground arms 102, 102A. Each first conductor arm 100 and second conductor arm 100A can be cantilevered from a stationary point, diverge from one another during mating, and/or have respective mating ends that move independently of one another. Each first ground arm 102 and second conductor arm 102A can be cantilevered from a stationary point, diverge from one another during mating, and/or have respective mating ends that move independently of one another. A friction boot 104 of first cable connector 78 can define a cable polarization feature that is similarly sized and shaped to the mating block 34 polarization feature 36 shown in FIG. 1. The friction boot 104 can removably slide over the mating block 34 in only one orientation, with the polarization feature 36 aligned with the cable polarization feature 106 defined by the friction boot 104.
(35) FIG. 8 shows the second cable assembly end 84 of cable assembly 76. Second and third cable connectors 80, 82 are shown, with second cable connector 80 partially disassembled. Each second and third cable connector 80, 82 can include an electrically conductive outer shell 108, and the electrically conductive outer shell 108 can be made from one or more pieces of electrically conductive metal. Each outer shell 108 can be electrically, physically, or both electrically and physically connected to a respective cable ground or shield (not shown) of a respective one of the first and second cables 86, 86A. Each outer shell 108 can be internally threaded 110, externally threaded or devoid of internal or external threads.
(36) The second cable connector 80 can include a second cable connector conductor 112, for example, an RF connector. Third cable connector 82 can include a third cable connector conductor 114, for example, an RF connector. The second cable connector conductor 112 can be electrically insulated from a respective outer shell 108 by a spacer 116 that can encircle the second cable connector conductor 112. The third cable connector conductor 114 can be electrically insulated from a respective outer shell 108 by an electrically insulative spacer 116A that can encircle the third cable connector conductor 114.
(37) A first cable conductor (not shown) of first cable 86 can be electrically, physically, or both electrically and physically connected to the second cable connector conductor 112. A second cable conductor (not shown) of second cable 86A can be electrically, physically, or both electrically and physically connected to the third cable connector conductor 114. A first cable ground shield (not shown) of first cable 86 can be electrically, physically, or both electrically and physically connected to a respective outer shell 108 of the second cable connector 80. A second cable ground shield (not shown) of second cable 86A can be electrically, physically, or both electrically and physically connected to a respective outer shell 108 of the third cable connector 82. The second and third and cable connector conductors 112, 114 can be electrically insulated from one another and from one or both of the outer shells 108.
(38) Preferably, a first transmission line is fully shielded between the first cable connector conductor 90 to the second cable connector conductor, and a second transmission line is fully shielded between the another first cable connector conductor 92 and the third cable connector conductor 114. However, one or both of the first transmission line and the second transmission line can be not fully shielded.
