Description
- This application is a continuation of U.S. patent application Ser. No. 16/521,073, filed Jul. 24, 2019, which is a continuation of U.S. patent application Ser. No. 15/468,893 (now U.S. Pat. No. 10,530,072), filed Mar. 24, 2017, which claims the benefit and priority of U.S. Provisional Patent Application No. 62/312,891, filed Mar. 24, 2016. U.S. patent application Ser. No. 15/468,893 is also a continuation-in-part of U.S. patent application Ser. No. 15/290,216, filed Oct. 11, 2016, which claims benefit and priority of U.S. Provisional Patent Application No. 62/239,685, filed Oct. 9, 2015. The entire contents of each of these documents is incorporated herein by reference.
- In a typical building, ground potential in the electrical systems of the building needs to be equalized for all networks so that different networks function properly. For example, a power line and cable television (CATV) network require equal ground potentials as they utilize common equipment. For developed countries, the ground installation and setup may be regulated, and thus the networks in a building may not experience issues. On the other hand, other jurisdictions where regulation is less, improper grounding may become an issue when different networks have different ground potentials.
- When two networks are connected, for example, when a cable is connected to the CATV set top box, a current will flow from CATV network to a neutral line of the set top box or vice versa if the ground potentials are not equal. In some cases, this current may reach levels that damage the set top box, and may even become hazardous to the user or installer. Therefore, the neutral lines of these networks need to be isolated to prevent current flow.
- Currently, there are isolators available to address this problem. However, the available isolators are bulky and expensive. For example, in some isolators, isolation is achieved on a printed circuit board that has two ground metallization: one side of the metalization connected to a female connector side and the other side of the metalization to a male connector. The coupling between two ground metalizations is achieved via a coupling capacitor and electromagnetic interference (EMI) filtering is achieved on the printed circuit board from one side metalization to the other using ferrites. This configuration results in large and bulky isolators.
- An isolator is disclosed. The isolator includes an outer shield configured to provide a radio-frequency (RF) barrier. The isolator also includes a body positioned at least partially within the outer shield. The body is configured to be connected to a user device. The isolator also includes a conditioning circuit positioned at least partially within the outer shield, the body, or both. The conditioning circuit is configured to filter signals communicated therethrough. The isolator also includes a coupling member positioned at least partially within the outer shield, the body, or both. The coupling member has an anti-rotation feature that is configured to prevent the conditioning circuit from rotating with respect to the coupling member to maintain a stable ground contact for the conditioning circuit. The isolator also includes a first annular circuit positioned radially between the coupling member and the outer shield, the body, or both. The isolator also includes a second annular circuit positioned radially between the coupling member and the outer shield, the body, or both. The first and second annular circuits are axially offset from one another with respect to a central longitudinal axis that extends therethrough. The first and second annular circuits are configured to provide RF coupling between the coupling member and the outer shield, the body, or both.
- In another embodiment, the isolator includes a conditioning circuit configured to filter signals communicated therethrough. The isolator also includes a coupling member comprising an anti-rotation feature. The anti-rotation feature is configured to prevent the conditioning circuit from rotating with respect to the coupling member to maintain a stable ground contact for the conditioning circuit. The isolator also includes a first annular circuit positioned around the coupling member. The isolator also includes a second annular circuit positioned around the coupling member and axially offset from the first annular circuit. The first and second annular circuits are configured to provide radio-frequency (RF) coupling with the coupling member.
- In another embodiment, the isolator includes an anti-rotation feature that is configured to be positioned within a body of the isolator. The anti-rotation feature is configured to receive a circuit and to prevent the circuit from rotating within the body to maintain a stable ground contact for the circuit.

- An isolator in accordance with aspects of the present disclosure provides EMI filtering, ground coupling, and/or surge protection, which can protect a PCB housed within the isolator. In some implementations, the PCB can be a coaxial PCB, which can be connected within the isolator during assembly solely by compression fitting (e.g., without additional attachments, such as solder or adhesive). Additionally, because the PCB includes a coaxial design, space utilized by the coaxial PCB in the isolator is reduced. Further, in some implementations of the isolator, the coaxial PCB can provide ground connections between two isolated cavities. Moreover, in some implementations, the isolator includes an RF filtering cavity surrounding the coaxial PCB and one or more toroids to filter RF signals to reduce EMI.
- According to additional aspects of the present disclosure, the isolator can include an insulating grip formed on an exterior of the isolator. The insulating grip can be formed of an insulating sleeve that surrounds an exterior portion of the isolator. The insulating grip can provide electrical shock protection for a user, for example, an installer, handling the isolator. The insulating grip can also provide protection against shorting two insulated sides of the isolators for additional safety to hardware coupled to the isolator. Additionally, the insulating grip can include raised members that provide friction and improve handling and installation. Further, the insulating grip can provide improved aesthetic design for the isolator by providing colors and patterns to an exterior of the isolator.

FIGS. 1A-1E illustrate examples of anisolator 100, according to various implementations.FIG. 1A illustrates an exploded, three-dimensional view of theisolator 100, andFIG. 1B illustrates a two-dimensional, cross-sectional view of theisolator 100.FIG. 1C illustrates an exploded, three-dimensional view of theisolator 100 with an insulating grip.FIG. 1D illustrates a three-dimensional view of theisolator 100 with the insulating grip.FIG. 1E illustrates a three-dimensional view of theisolator 100 with a two stage design. WhileFIGS. 1A-1E illustrate various components contained in theisolator 100,FIGS. 1A-1E illustrate one example of an isolator and additional components can be added and existing components can be removed. - As shown in
FIGS. 1A and 1B , theisolator 100 can include abody 102 that includes acoupler 104, a threadednut 105, and anouter shield 106 arranged along acentral axis 150. In some implementations, theisolator 100 can be a coaxial radio frequency (RF) isolator, in which thebody 102, thecoupler 104, the threadednut 105, and theouter shield 106 are positioned coaxially around a commoncentral axis 150 of the isolator. Thecoupler 104 can be a female (or male) connector that includes one or more threads that can connect to a male (or female) coaxial connector of, for example, a RG-6 coaxial cable. The threadednut 105 can be screwed onto the threads of the connector. Theouter shield 106 can be configured to slide over a portion of thebody 102 up to alip 110. In some implementations, thebody 102 and theouter shield 106 form an internal cavity for the components within theisolator 100. In some implementations, theouter shield 106 can be compression fitted over thebody 102 such that the two can be securely attached without the use of, for example, an adhesive material or solder. Thebody 102 and theouter shield 106 can be formed of a conductor material, for example, a metal or metal alloy. In some implementations, theisolator 100 can also include aspacer 108. Thespacer 108 can be formed with an annular shape (e.g., a cylindrical ring) to be placed over a portion of thebody 102. Thespacer 108 can be formed a dielectric material, such as a plastic insulator. When theouter shield 106 is compression-fitted over thebody 102, thespacer 108 can fit between thelip 110 of thebody 102 and aninner lip 112 of theouter shield 106. - In some implementations, the
isolator 100 can include asleeve 114 that can include aperipheral lip 116. Theperipheral lip 116 can be formed such that an outer diameter of thesleeve 114 at theperipheral lip 116 is smaller than an outer diameter the remaining portion of thesleeve 114, while the inner diameter of thesleeve 114 is substantially the same over the length of thesleeve 114. Theperipheral lip 116 can be configured to receive thespacer 108. Thesleeve 114 can be formed of a dielectric material, for example, a plastic insulator. Thesleeve 114 can be placed between theouter shield 106 and thebody 102. In embodiments, the outer diameter of theperipheral lip 116 can be substantially the same as an inner diameter of thespacer 108. Thespacer 108 and the sleeve can create an electrically-insulating barrier between thebody 102 and theouter shield 106 that electrically isolates thebody 102 from theouter shield 106 when the shield is compression fitted on thebody 102. - In some implementations, the
isolator 100 can include a coupling/filtering member 118. The coupling/filtering member 118 can be pressed inside theouter shield 106 to form a smaller internal cavity that is used for the components of theisolator 100, as further described below with reference toFIGS. 2A and 2B . The coupling/filtering member 118 can be formed of a conductive material, for example, a metal or metal alloy. -
FIG. 2A illustrates an example of the filtering/coupling member 118, according to various implementations. As shown, filtering/coupling member 118 can be formed in a generally-cylindrical shape with increasingouter diameters filtering member 118 can be hollow, forming acavity 207 therein. The coupling/filtering member 118 can also includeslots 208 proximal to an axial end thereof. Theslots 208 may be configured to receive and hold a PCB assembly (e.g., PCB 120) stable, for example, to prevent such PCB assembly from rotating freely in thecavity 207 with respect to the filter/coupling member 118, or to be used as a ground contact for the PCB assembly. - With continuing reference to
FIG. 2A ,FIG. 2B illustrates the filtering/coupling member 118 received into theouter shield 106. As shown, theouter shield 106 can be at least partially formed as acylindrical member 210 including afirst opening 212 and asecond opening 214. The first andsecond openings first opening 212 can define a larger diameter than thesecond opening 214. Thesecond opening 214 can be configured to receive the filtering/coupling member 118. Accordingly, the filtering/coupling member 118 can, in some embodiments, be received into theouter shield 106 through thefirst opening 212 and seated into thesecond opening 214. When the filtering/coupling member 118 is received into thesecond opening 214, anannular cavity 216 can be defined between (e.g., by) theouter shield 106 and the coupling/filtering member 118. Thecylindrical member 210 can also include one or more (e.g., internal)threads 218 to connect to theisolator 100 to a cable or device connected to the output of theisolator 100. Thethreads 218 of the coupling/filtering member 118 can provide a male (or female) connector that can connect to a female (or male) coaxial connector of, for example, a RG-6 coaxial cable. In some implementations, the filtering/coupling member 118 can be designed as a part of theouter shield 106 to reduce the assembly part count. In this implementation, the coupling/filtering member 118 and theouter body 106 can be a single part or structure. - Returning to
FIGS. 1A and 1B , theisolator 100 can include aPCB 120. ThePCB 120 can be coupled between aPCB coupler 122 and anoutput pin 124. ThePCB coupler 122 can be configured to receive a male pin from a device or cable connected to thecoupler 104. Theoutput pin 124 can be configured to conduct signals to/from devices or cables connected to theisolator 100. Theisolator 100 can include a support and sealingmember 128 at or proximal to an axial end of theouter shield 106. The support and sealingmember 128 can be formed in a cylindrical shape with a hole to receive theoutput pin 124. The support and sealingmember 128 can be configured to hold theoutput pin 124 in place for connection of devices or cables to theisolation device 100. - The
PCB 120 can be configured to condition signals passing from thePCB coupler 122 to theoutput pin 124. ThePCB 120 can include any type ofcircuitry 126 to provide filtering and conditioning to the signals passing from thePCB coupler 122 to theoutput pin 124. For example, thePCB 120 can include one or more low-pass filters, bandpass filters, band reject filters, high-pass filters, amplifiers, diplexers, Multimedia over Coax Alliance (MoCA) filters, and the like. ThePCB 120, thePCB coupler 122, and theoutput pin 124 include an RF signal transmission path through the coupling/filtering member 118 that conductively couples devices and/or cables connected at the input (e.g., coupler 104) and the output (e.g., threads 218) of theisolator 100. In some implementations, the PCB 120 (including the circuitry 126), thePCB coupler 122, and theoutput pin 124 can be combined into a single assembly. - In some implementations, the
isolator 100 includes acoaxial PCB 130. Thecoaxial PCB 130 can be configured to provide a connection between thebody 102 and the filtering/coupling member 118 and theouter shield 106. Whilecoaxial PCB 130 is illustrated as having cylindrical (e.g., annular) shape, thecoaxial PCB 130 can be formed using other profiles (e.g., rectangular, triangular, oval, etc.). -
FIGS. 3A-3E illustrate different views of examples of thecoaxial PCB 130, according to various implementations. In particular,FIG. 3A illustrates a perspective view of afront 300 of thecoaxial PCB 130, andFIG. 3B illustrates a perspective view of a rear 302 of thecoaxial PCB 130. As illustrated, thecoaxial PCB 130 can include anisolator ring 304 positioned between anouter conductor layer 306 andinner conductor layer 308. Theisolator ring 304 can be formed of a dielectric material, for example, a plastic insulator. Theisolator ring 304 can be formed from a substrate material, for example, FR4 substrate. Theouter conductor layer 306 and theinner conductor layer 308 can be formed of a conductive material, for example, a metal or metal alloy. Theouter conductor layer 306 can be positioned at or proximal to an outer diameter of thePCB 130, and theinner conductor layer 308 may be positioned at or proximal to an inner diameter thereof. - The
coaxial PCB 130 can include one or more surface mounted circuits 310 (e.g., a surface mounted technology (SMT) circuit) placed on theisolator ring 304 and a plated via ahole 312 formed axially in (e.g., through) theisolator ring 304. Thehole 312 can be formed at least partially from conductive material, for example, a metal or metal alloy. In some implementations, for example, the one or more surface mountedcircuits 310 can include capacitive circuits, inductive circuits, resistive circuits, filtering circuits, and the like. Theouter conductor layer 306 and theinner conductor layer 308 can be electrically coupled through the one or more surface mountedcircuits 310. -
FIGS. 3C and 3D illustrate examples of another example ofcoaxial PCB 130, according to various implementations. In particular,FIG. 3C illustrates a view of afront 350 of thecoaxial PCB 130, andFIG. 3D illustrates a view of a rear 352 of thecoaxial PCB 130. Thecoaxial PCB 130 can include anisolator ring 354 positioned between two layers: anouter conductor layer 356 and aninner conductor layer 358. Thetop layer 356 can include one or more surface mounted circuit footprints 362 (e.g., four footprints), which can receive one or more surface mounted circuits. Theisolator ring 354 can be formed of a dielectric material, for example, a plastic insulator. Theisolator ring 354 can be formed from a substrate material, for example, FR4 substrate. Theouter conductor layer 356 and theinner conductor layer 358 can be formed of a conductor material, for example, a metal or metal alloy. - The
coaxial PCB 130 illustrated inFIGS. 3C and 3D can include one or more surface mounted circuits (not shown) placed on theisolator ring 354 and one or more plated viaholes 360 formed in theisolator ring 304 and electrically coupled to thecircuit footprints 362. The plated viaholes 360 can be formed of a conductor material, for example, a metal or metal alloy. Theouter conductor layer 356 and theinner conductor layer 358 can be electrically coupled through the one or more surface mounted circuits. - In some implementations, the
coaxial PCB 130 can function to block direct current (DC) current flow between thebody 102, and theouter shield 106 and coupling/filtering member 118. For example, thecoaxial PCB 130 can be placed in theisolator 100 so that the outer ring conductor 306 (or the outer ring conductor 356) is in electrical contact with thebody 102, and the inner ring conductor 308 (or inner ring conductor 358) is in electrical contact with the coupling/filtering member 118. For example, the inner diameter of thecoaxial PCB 130 can be configured to fit over any of thediameters filtering member 118 depending on the configuration of theisolator 100, as further discussed below inFIGS. 4A-4D . -
FIG. 3E illustrates an implementation of thecoaxial PCB 130. As illustrated inFIG. 3E , thecoaxial PCB 130 can include anisolator ring 384 positioned between anouter ring conductor 386 andinner ring conductor 388. Theisolator ring 384 can be formed from a dielectric material, (e.g., a substrate material, such as a FR4 substrate). Theouter ring conductor 386 and theinner ring conductor 388 can be formed of a conductive material, for example, a metal or metal alloy, plated copper, copper etc. In some implementations, one ormore areas 390 of theouter ring conductor 386 can be removed to accommodate support edges (not shown) for high volume PCB manufacturing. - Returning again to
FIGS. 1A and 1B , in some implementations thecoaxial PCB 130 illustrated inFIGS. 3C and 3D can function as a filter that blocks direct current (“DC”) flow between thebody 102, and theouter shield 106 and coupling/filtering member 118 by deploying capacitive coupling elements such as capacitors. For example, thecoaxial PCB 130 can be placed in theisolator 100 so that the outer conductor layer 306 (or the outer conductor layer 356) is in electrical contact with thebody 102 and the inner conductor layer 308 (or inner conductor layer 358) is in electrical contact with the coupling/filtering member 118. For example, the inner diameter of thecoaxial PCB 130 can be configured to fit over any of thediameters filtering member 118 depending on the configuration of theisolator 100, as further discussed below in reference toFIGS. 4A-4D . - Still referring to
FIGS. 1A and 1B , theisolator 100 can include one ormore toroids 132 configured to filter and/or attenuate RF signal ingress into theisolator 100 or RF signal egress from theisolator 100 that may be induced by signals traveling through theisolator 100. Thetoroids 132 can be formed of a magnetic material (e.g., ferrite) having for example, a cylindrical shape. In accordance with aspects of the present disclosure, the one ormore toroids 132 can be positioned axially adjacent to thecoaxial PCB 130 and surrounding a portion of the coupling/filtering member 118 within the RF filtering cavity (e.g., inner cavity 216). In some implementations, the inner diameter of thetoroid 132 can be formed to any of thediameters filtering member 118.
