The disclosure relates generally to a twin-axial cable including wedges.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes, thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Cables have become an integral part of information handling systems, include servers. Within a rack, across multiple racks, and across multiple servers (within a rack), communication is accomplished through cables. The cables can further connect one or more PCBs. Cables provide a lower loss mode for signal propagation compared to PCBs.
Innovative aspects of the subject matter described in this specification may be embodied in a twin-axial cable including a first conductor; a first dielectric material surrounding the first conductor; a second conductor; a second dielectric material surrounding the second conductor; a first wedge; a second wedge positioned opposite to the first wedge; and a conductive shield surrounding the first conductor, the first dielectric material, the second conductor, the second dielectric material, the first wedge, and the second wedge, wherein at least a portion of the first wedge is positioned between the first dielectric material and the second dielectric material at a first region of the twin-axial cable, wherein at least a portion of the second wedge is positioned between the first dielectric material and the second dielectric material at a second region of the twin-axial cable opposite to the first region of the twin-axial cable.
Other embodiments of these aspects include corresponding systems and apparatus.
These and other embodiments may each optionally include one or more of the following features. For instance, when the twin-axial cable is in a first state, the first wedge is spaced-apart from the second wedge a first distance. When the first wedge is spaced-apart from the second wedge the first distance: an outer surface of the first dielectric material is spaced-apart from an outer surface of the first conductor a second distance, wherein the second distance is substantially constant between the outer surface of the dielectric material and the outer surface of the first conductor; an outer surface of the second dielectric material is spaced-apart from an outer surface of the second conductor the second distance, wherein the second distance is substantially constant between the outer surface of the dielectric material and the outer surface of the first conductor; and the outer surface of the first conductor is spaced-apart from the outer surface of the second conductor a third distance, wherein a first impedance of the twin-axial cable is based on the second distance and the third distance. When the twin-axial cable is in a second state, the first wedge is spaced-apart from the second wedge a fourth distance, the fourth distance less than the first distance. When the first wedge is spaced-apart from the second wedge the fourth distance: the outer surface of the first dielectric material is spaced-apart from the outer surface of the first conductor a fifth distance at a first and a second location of the first dielectric material, the first location opposite to the second location, the fifth distance less than the second distance; the outer surface of the second dielectric material is spaced-apart from the outer surface of the second conductor the fifth distance at a third and a fourth location of the first dielectric material, the third location opposite to the fourth location; and the outer surface of the first dielectric material is spaced-apart from the outer surface of the second dielectric material a sixth distance, wherein the sixth distance is greater than the third distance, wherein a second impedance of the twin-axial cable is based on the fifth distance and the sixth distance. The first impedance is substantially the same as the second impedance. The first wedge and the second wedge are conductive. The first wedge is conductive, and the second wedge is non-conductive. The first wedge and the second wedge are equilateral triangles.
The details of one or more embodiments of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other potential features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.
This disclosure discusses a twin-axial cable of an information handling system. In short, the twin-axial cable can be bent such that a conductive shield of the twin-axial cable compresses dielectric material surrounding conductors of the twin-axial cable. To compensate for an impedance drop of the twin-axial cable when the conductive shield compresses the twin-axial cable, concurrently when the conductive shield compresses the dielectric material, the conductive shield forces wedges of the twin-axial cable together to decrease the gap therebetween. When the distance between the wedges is decreased, the distance between the conductors is increased. When the distance between the conductors is increased, the impedance of the twin-axial cable is increased, compensating for the drop in impedance when the conductive shield compresses the twin-axial cable, described further herein.
Specifically, this disclosure discusses a twin-axial cable including a first conductor; a first dielectric material surrounding the first conductor; a second conductor; a second dielectric material surrounding the second conductor; a first wedge; a second wedge positioned opposite to the first wedge; and a conductive shield surrounding the first conductor, the first dielectric material, the second conductor, the second dielectric material, the first wedge, and the second wedge, wherein at least a portion of the first wedge is positioned between the first dielectric material and the second dielectric material at a first region of the twin-axial cable, wherein at least a portion of the second wedge is positioned between the first dielectric material and the second dielectric material at a second region of the twin-axial cable opposite to the first region of the twin-axial cable.

In short, the twin-axial cable 206 can be bent such that the conductive shield 302 compresses the dielectric material 306. To compensate for an impedance drop of the twin-axial cable 206 when the conductive shield 302 compresses the twin-axial cable 206, concurrently when the conductive shield 302 compresses the dielectric material 306, the conductive shield 302 forces the wedges 308 together to decrease the gap therebetween. When the distance between the wedges 308 is decreased, the distance between the conductors 304 is increased. When the distance between the conductors 304 is increased, the impedance of the twin-axial cable 206 is increased, compensating for the drop in impedance when the conductive shield 302 compresses the twin-axial cable 206, described further herein.
The first dielectric material 306a surrounds the first conductor 304a. The second dielectric material 306b surrounds the second conductor 304b. The conductive shield 302 surrounds the first conductor 304a, the second conductor 304b, the first dielectric material 306a, the second dielectric material 306b, the first wedge 308a, and the second wedge 308b.
The first wedge 308a can be positioned at a first region 402 of the twin-axial cable 206. The first wedge 308a can be positioned between the first dielectric material 306a and the second dielectric material 306b at the first region 402 of the twin-axial cable 206. That is, a portion 410 of the first wedge 308a can be positioned between the first dielectric material 306a and the second dielectric material 306b at the first region 402 of the twin-axial cable 206.
The second wedge 308b can be positioned at a second region 404 of the twin-axial cable 206, the second region 404 opposite to the first region 402. The second wedge 308b can be positioned between the first dielectric material 306a and the second dielectric material 306b at the second region 404 of the twin-axial cable 206. That is, a portion 412 of the second wedge 308b can be positioned between the first dielectric material 306a and the second dielectric material 306b at the second region 404 of the twin-axial cable 206.
In some examples, the first wedge 308a and the second wedge 308b are both conductive. In some examples, only one of the first wedge 308a and the second wedge 308b is conductive, and the other is non-conductive. In some examples, the first wedge 308a and the second wedge 308b are equilateral triangles. In some examples, the first wedge 308a and the second wedge 308b include rounded corners. The wedges 3008 can have any shape desired, any type of triangular shape, or any geometry as desired.
To that end, when the twin-axial cable 206 is in a first state, as shown in
Moreover, when the twin-axial cable 206 is in the first state, an outer surface 424 of the second dielectric material 306b is spaced-apart from an outer surface 426 of the second conductor 304b the second distance D2. The second distance D2 is substantially constant between the outer surface 424 of the second dielectric material 306b and the outer surface 426 of the second conductor 304b around the second conductor 304b when the twin-axial cable 206 is in the first state. That is, the dielectric materials 306 are in contact with each other when the twin-axial cable 206 is in the first state.
Moreover, when the twin-axial cable 206 is in the first state, the outer surface 416 of the first conductor 304a is spaced-apart from the outer surface 426 of the second conductor 304b a third distance D3.
To that end, when the twin-axial cable 206 is in the first state, the twin-axial cable 206 can be associated with a first impedance. The first impedance of the twin-axial cable 206 can be based on the second distance D2 and the third distance D3. That is, the first impedance of the twin-axial cable 206 can be based on the distances between the conductors 304 and the respective outer surfaces of the dielectric materials 306, and a distance between the conductors 304 when the twin-axial cable 206 is in the first state.
To that end, when the twin-axial cable 206 is in a second state, the first wedge 308a is spaced-apart from the second wedge 308b a fourth distance D4, as shown in
Referring to
Moreover, when the twin-axial cable 206 is in the second state, the outer surface 424 of the second dielectric material 306b is spaced-apart from the outer surface 426 of the second conductor 304b the fifth distance D5 at a first location 722 and a second location 724. The first location 722 is opposite to the second location 724.
Moreover, when the twin-axial cable 206 is in the second state, the outer surface 416 of the first conductor 304a is spaced-apart from the outer surface 426 of the second conductor 304b a sixth distance D6. The sixth distance D6 is greater than the third distance D3, shown in
Specifically, the twin-axial cable 206 can be bent such that the conductive shield 302 compresses (at least) the first dielectric material 306a at the first location 702 and the second location 704 and compresses (at least) the second dielectric material 306b at the first location 722 and the second location 724. To compensate for an impedance drop of the twin-axial cable 206 when the conductive shield 302 compresses the twin-axial cable 206, concurrently when the conductive shield 302 compresses the dielectric material 306, the conductive shield 302 forces the wedges 308 together to decrease the gap therebetween. That is, the conductive shield 302 forces the wedges 308 together to decreases the distance DI (as shown in
To that end, when the twin-axial cable 206 is in the second state, the twin-axial cable 206 can be associated with a second impedance. The second impedance of the twin-axial cable 206 can be based on the fifth distance D5 and the sixth distance D6. That is, the second impedance of the twin-axial cable 206 can be based on the distances between the conductors 304 and the respective outer surfaces of the dielectric materials 306, and a distance between the conductors 304 when the twin-axial cable 206 is in the second state.
To that end, as the spacing between the conductors 204 increases when in the second state as compared to the first state (increasing from distance D3 to distance D6) and the spacing between the conductors 304 and outer surfaces of respective dielectric materials 306 decreases when in the second state as compared to the first state (decreasing from distance D3 to distance D5), the second impedance of the twin-axial cable 206 in the second state is the same, or substantially the same, as the first impedance of the twin-axial cable 206 in the first state.
