Description
- The present invention claims the benefit of and priority from U.S. patent application Ser. No. 14/823,485, filed Aug. 11, 2015, and from U.S. Provisional Patent Application No. 62/036,258, filed Aug. 12, 2014, the disclosure of each of which is hereby incorporated herein in its entirety.
- The present invention is directed generally to electrical cable connectors, and more particularly to coaxial connectors for electrical cable.
- Coaxial cables are commonly utilized in RF communications systems. A typical coaxial cable includes an inner conductor, an outer conductor, a dielectric layer that separates the inner and outer conductors, and a jacket that covers the outer conductor. Coaxial cable connectors may be applied to terminate coaxial cables, for example, in communication systems requiring a high level of precision and reliability.
- Coaxial connector interfaces provide a connect/disconnect functionality between (a) a cable terminated with a connector having a particular connector interface and (b) a corresponding connector with a mating connector interface mounted on an apparatus or on another cable. Typically, one connector will include a structure such as a pin or post connected to an inner conductor and an outer conductor connector body connected to the outer conductor; these are mated with a mating sleeve (for the pin or post of the inner conductor) and another outer conductor connector body of a second connector, wherein one of the outer conductor bodies fits within the other outer conductor body Coaxial connector interfaces often utilize a threaded coupling nut or other retainer that draws the connector interface pair into secure electro-mechanical engagement when the coupling nut (which is captured by one of the connectors) is threaded onto the other connector.
- Passive Intermodulation Distortion (PIM) is a form of electrical interference/signal transmission degradation that may occur with less than symmetrical interconnections and/or as electro-mechanical interconnections shift or degrade over time. Interconnections may shift due to mechanical stress, vibration, thermal cycling, and/or material degradation. PIM can be an important interconnection quality characteristic, as PIM generated by a single low quality interconnection may degrade the electrical performance of an entire RF system. Thus, the reduction of PIM via connector design is typically desirable.
- One manner of addressing PIM is to create connectors that capacitively couple when connected, rather than galvanically coupling through direct electrical contact in the manner of conventional connectors. In one example, the inner conductor post of one connector is covered with a dielectric layer, as is the outer surface of one of the outer conductors. When the two connectors are engaged, the dielectric layers insulate the conductors from each other, thereby creating a capacitive coupling between conductors. Capacitively coupled connectors may decrease PIM caused by minute debris contaminating the metallic connection normally found in mating RF connectors. Because physical contact is not required to couple RF energy through the interfaces, a major cause of contact debris, namely the contact force and wiping of the interfaces necessary for stable contact resistance, can be eliminated. An exemplary set of connectors of this type is shown in U.S. patent application Ser. No. 14/102,042, filed on Dec. 10, 2013, the disclosure of which is hereby incorporated herein in its entirety. However, other designs that employ capacitive coupling may also be desirable.

The connector comprises: a conductive common base with a contact surface; a plurality of conductive contact pads embedded in the common base, each of the plurality of contact pads having a contact surface; and a plurality of dielectric pads embedded in the common base, each of the dielectric pads surrounding a respective contact pad to isolate the respective contact pad from the common base.
- As a second aspect, embodiments of the invention are directed to an assembly of coaxial cable connectors comprising a first connector and a second connector. The first connector comprises: a first conductive common base with a contact surface; a plurality of first conductive contact pads embedded in the first common base, each of the plurality of first contact pads having a contact surface; and a plurality of first dielectric pads embedded in the first common base, each of the first dielectric pads surrounding a respective first contact pad to isolate the respective first contact pad from the first common base.

The first connector and the second connector are arranged such that the contact surface of the first base confronts the contact surface of the second base separated by the dielectric layer, and the contact surface of the first contact pad confronts the contact surface of the second contact pad separated by the dielectric layer.
- As a fifth aspect, embodiments of the invention are directed to a connector for transmitting an RF signal, comprising: a conductive base with a contact surface; a contact pad embedded in the base; a dielectric pad embedded in the base to isolate the contact pad from the base; and a dielectric layer overlying the contact surface of the base and the contact pad.

- Referring now to the figures, a coaxial cable assembly, designated broadly at 10, is shown in
FIGS. 1-4A . The assembly 10 (seeFIG. 3 ) includes afirst connector 20 and asecond connector 120. Theseconnectors - Referring now to
FIG. 1 , theconnector 20 is illustrated therein. Theconnector 20 includes a generally squarecommon base 22 with a circularcentral portion 23. Within thecentral portion 23 are fourcontact pads 24 encircled bydielectric pads 26. Thecentral portion 23 has a facingsurface 23 a, the contact pads have facingsurfaces 24 a, and thedielectric pads 26 have facingsurfaces 26 a. The facingsurfaces contact pads 24 is connected with a respectivecoaxial cable 50 comprising aninner conductor 52, adielectric layer 54, anouter conductor 56 and a jacket 58 (seeFIG. 4 ). - As can be seen in
FIGS. 4 and 4A , each of thecontact pads 24 has a disk-shaped.main body 28 and acircular boss 30 that extends generally normal thereto. Thebore 32 in theboss 30 is configured to receive and be electrically connected with theinner conductor 52 of a respectivecoaxial cable 50. Each of thecontact pads 24 is embedded in arespective dielectric pad 26. Eachdielectric pad 26 has a stepped profile, with awider ring 38 within which themain body 28 lies and anarrower ring 40 that encircles theboss 30. Thedielectric layer 54 of thecoaxial cable 50 meets the end of thenarrower ring 40, thereby electrically isolating theinner conductor 52 and thecontact pad 24 from, respectively, theouter conductor 56 and thecentral portion 23 of thecommon base 22. - The
central portion 23 of theconnector 20 includes four steppedpockets 44 within which the dielectric pads 26 (and, in turn, the contact pads 24) are embedded. As used herein, the word “embedded” means that some portion of one component or structure is positioned within and below the surface of another component or structure. Acircular boss 46 extends from eachpocket 44 to contact and electrically connect with theouter conductor 56 of thecoaxial cable 50. Thus, thecentral portion 23 of thecommon base 22 is electrically and commonly connected to all of theouter conductors 56 of thecoaxial cables 50. - The
contact pads 24 andcentral portion 23 are formed of an electrically conductive material. Exemplary materials for thecontact pads 24 and thecentral portion 23 are copper, brass and bronze. - Referring still to
FIGS. 4 and 4A , a dielectric layer orcoating 48 overlies the facing surfaces 23 a, 24 a, 26 a of thecentral portion 23, thecontact pads 24 and thedielectric pads 26. Thedielectric layer 48 is typically between about 0.001 and 0.004 inches in thickness and is formed of a dielectric material such as polyester film. - The
second connector 120 is similar in many respects to the connector 20: it has fourcontact pads 124 embedded within acommon base 122, each of which is encircled by a respective dielectric pad 126 (seeFIG. 2 ). Thecontact pads 124 and the base 122 are connected to respectivecoaxial cables 150, with theinner conductors 152 of thecoaxial cables 150 being electrically connected to thecontact pads 124, and theouter conductors 156 of thecoaxial cables 150 being electrically connected to the common base 122 (seeFIG. 4 ). Thecommon base 122 of theconnector 120 is circular and sized to match thecentral portion 23 of theconnector 20. Adielectric layer 148 overlies the facingsurfaces 124 a of thecontact pads 124, the facingsurfaces 126 a of thedielectric pads 126, and the facingsurface 122 a of the common base 122 (seeFIGS. 2 and 4A ). - As is shown in
FIGS. 3 and 4 , theconnector 20 and theconnector 120 can be mated to provide a capacitively coupled interconnection between thecoaxial cables 20 and thecoaxial cables 120. Each of thecontact pads 24 of theconnector 20 aligns with acorresponding contact pad 124 of theconnector 120, such that their facingsurfaces dielectric layers dielectric pads 26 aligns with a correspondingdielectric pad 126, such that their facingsurfaces dielectric layers - Referring now to
FIG. 5 , anassembly 200 comprising afirst connector 220 and asecond connector 320 is shown therein. Theconnector 220 is identical to theconnector 20 ofFIG. 1 with the exception that it includes two ears 262 (withalignment holes 262 a) extending outwardly from opposed top and bottom edges.Shoulder bolts 264 can be inserted through the holes 260 (located in the corners of the common base 222) to attach theconnector 220 to a panel or other structure. As shown, compression springs 266 may be inserted onto theshoulder bolts 264 to allow theconnector 220 to “float” relative to theconnector 320 during mating. Theconnector 320 is identical to theconnector 120 with the exception that it has twoears 362 on opposite top and bottom edges and twoadditional ears 364 extending from opposite side edges. Theears 362 havealignment holes 362 a that align with the alignment holes 262 a in theears 262 of theconnector 260. A non-conductive alignment pin 270 can be press-fit into theholes 262 a with minimal clearance with respect toholes 362 a to correctly orient theconnectors connector 320 is mounted to a structure such as a panel viabolts 368 inserted through holes 364 a in theears 364. - Those skilled in this art will appreciate that connectors according to embodiments of the invention may have more or fewer contact pads and dielectric pads than are shown herein; for example, a connector may have as few as one contact pad and one dielectric pad embedded in the base. Additionally, although the contact pads and dielectric pads are shown as being circular, other shapes (e.g., square, oval, rectangular, triangular, hexagonal, etc.) may also be employed. In the illustrated embodiment, the central portion of the common base and the contact pads are substantially coplanar, but in some embodiments may be slightly offset from each other. Also, in the illustrated embodiment, the contact surfaces of the common base and the contact pads are substantially flat, but in other embodiments they may be arcuate or otherwise non-flat.
- Also, it should be understood that, although a coaxial cable is illustrated herein as being attached to the connectors, other types of cables, such as stripline cables and microstrip transmission lines, may also be employed. One or both connectors may be mounted to a structure, such as the panel of an item of electronic equipment, that includes multiple connections in a ganged configuration.
- Further, although the connectors shown herein have their own overlying dielectric layers, in some embodiments only one of the connectors may have a dielectric layer overlying the contact pads and contact base, wherein the mating connector has no overlying dielectric layer. Such an arrangement can still provide a capacitively coupled interface between the connectors.
- In addition, the manner in which mating connectors are maintained in contact may vary. For example, hooks, latches and the like may be employed to hold mating connectors in position.
- The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims. The invention is defined by the following claims, with equivalents of the claims to be included therein.
