Technical Field

As data rates continue to increase, maintaining signal integrity becomes increasingly challenging. Cable assemblies operating at high frequencies are susceptible to electromagnetic interference, crosstalk, and other signal attenuation factors that can compromise performance and reliability. Shielding techniques have been employed to mitigate these problems in high-speed cable assemblies. However, as data rates push into higher frequency ranges (such as in OSFP 224G applications and above), traditional shielding methods can no longer provide sufficient protection.

[0048] This disclosure relates to an array of shielding for high-speed cable assemblies, and more specifically, describes an array of bottom shielding that can be used to provide improved signal integrity (SI) performance and other benefits. High-speed cable assemblies, particularly those involving biaxial cables connected to a substrate, may face numerous challenges in maintaining signal integrity and performance. As data rates increase, problems such as electromagnetic interference, crosstalk, and signal attenuation become more prominent. Conventional designs may struggle to provide adequate shielding and stability at the fragile terminations between the cable and the substrate.

[0049] These challenges are amplified in applications moving towards 224 Gb / s and higher. The extremely high frequencies involved make cable assemblies more susceptible to coupling between external noise sources and internal signals. Furthermore, maintaining consistent impedance and minimizing signal reflections becomes increasingly difficult at these data rates. The physical layout and shielding of cable terminations play a critical role in overall system performance.

[0050] Therefore, this document describes various embodiments of a high-speed cable assembly with improved signal integrity performance. A high-speed cable assembly may include: a printed circuit board; one or more biaxial cables; a bottom shield forming an array for each biaxial cable; and a top shield. The bottom shield array includes a plurality of individual U-shaped conductive shields corresponding to the respective biaxial cables. For example, the U-shaped conductive shields are positioned around the biaxial cables to provide shielding on three sides. The top shield can be electrically connected to the bottom shield array by various methods (such as soldering, laser welding, crimping, or interference fit). The assembly may also include a conductive material (such as a conductive foam) that electrically connects the top shield to a conductive foil of a biaxial cable, the conductive foil being exposed through an opening in the cable sheath.

[0051] In some embodiments, the biaxial cables in the assembly include: a pair of signal conductors mounted to or otherwise electrically connected to two conductive pads on the printed circuit board using a thermoforming or similar bonding process. The printed circuit board may have multiple layers with different geometries adapted to these conductors. A stabilizing strip may be located between the top shield and the bodies of the plurality of biaxial cables to stabilize the termination with the printed circuit board. In some embodiments, the stabilizing strip may be overmolded between the top shield and the bodies of the plurality of biaxial cables.

[0052] A bottom shield array retaining strip can hold or otherwise maintain the plurality of individual bottom shields in a desired layout, wherein the retaining strip can be formed of a non-conductive material. The conductive material (such as conductive foam) can be applied to the top shield, stamped, or formed into a portion of the top shield to create a conductive connection to a biaxial foil of a biaxial cable. The components described in the various embodiments herein are designed to address the challenges of maintaining signal integrity and performance in high-speed applications (especially those approaching 224 Gb / s and higher data rates) where issues such as electromagnetic interference, crosstalk, and signal attenuation become more significant.

[0053] Now turn to the attached diagram. Figure 1A top perspective view of a non-limiting example of a high-speed cable assembly 100 according to various embodiments is shown. The high-speed cable assembly 100 includes a printed circuit board 103 having a plurality of biaxial cables 106a…106d (collectively, “biaxial cables 106”) affixed thereto. Although multiple rows of biaxial cables 106 may be affixed to different areas of the printed circuit board 103, for convenience, the termination of a single row of biaxial cables 106a…106d is illustrated. The high-speed cable assembly 100 may include one or more bottom shields 109a…109d (collectively, “bottom shields 109”). In some embodiments, the bottom shields 109 correspond one-to-one with the biaxial cables 106. Thus, each biaxial cable 106 in the high-speed cable assembly 100 may include a corresponding bottom shield 109. As will be explained, the high-speed cable assembly 100 may include a top shield 112, which may be attached to a top surface of one or more bottom shields 109.

[0054] Figure 2 Show Figure 1 The same perspective view, in which, for illustrative purposes, the top shield 112 is omitted. See also... Figure 1 and Figure 2 Each biaxial cable 106 may include two signal conductors 115a and 115b (collectively referred to as "signal conductors 115"). However, in some embodiments, each biaxial cable 106 may include two signal conductors 115 and two ground conductors 118a and 118b (collectively referred to as "ground conductors 118").

[0055] Using various techniques, signal conductor 115 and ground conductor 118 can be mounted on multiple conductive pads on printed circuit board 103 or otherwise terminated for signal communication and grounding, respectively. In some embodiments, a thermoforming process (also known as thermoforming soldering) can be used to create a reliable connection between conductors 115, 118 and the pads. Alternatively, laser soldering can be used. In some embodiments, ground conductor 118 is not terminated to printed circuit board 103, but rather terminated to another conductive structure, which in turn can be grounded to printed circuit board 103.

[0056] In some embodiments, each biaxial cable 106 may include a conductive biaxial foil 121 providing electromagnetic shielding for internal conductors. The biaxial foil 121 may be exposed through an opening or notch on the sheath 124 of the biaxial cable 106 at a location corresponding to the top shield 112. The exposed biaxial foil 121 allows electrical connections to other components of the assembly 100, such as the top shield 112 and / or a conductive material located between the top shield 112 and the biaxial foil 121, which can enhance overall shielding effectiveness and signal integrity. The location and size of the opening on the sheath 124 can be designed to optimize electrical connections while maintaining the mechanical integrity of the biaxial cable 106. In some cases, the exposed portion of the biaxial foil 121 may be selectively processed or prepared to improve conductivity or adhesion to other conductive elements in the assembly 100.

[0057] Figure 3 An enlarged top-view perspective view shows the biaxial cable 106 terminated at a printed circuit board 103. Figure 3 In this configuration, the bottom shield 109 includes a U-shaped conductive material forming a U-shaped wall around the termination of the biaxial cable 106. Each biaxial cable 106 can be terminated hereinstantly in an area enclosed by the U-shaped conductive material, wherein the bottom shield 109 surrounds the two conductors 115, 118 and the termination area. Each bottom shield 109 may be located on three sides to surround the corresponding biaxial cable 106, providing electromagnetic shielding for the termination area. This arrangement can aid signal integrity by reducing electromagnetic interference and crosstalk between the terminations of adjacent cables. The open top of the bottom shield 109 allows for visual inspection of the termination and provides additional shielding elements (such as the top shield 112) for further shielding. Figure 3 (Not shown) provides input / output.

[0058] In some embodiments, the bottom shield 109 is formed of a conductive material (such as metal) and can be bent or otherwise precisely shaped to fit snugly around the biaxial cable 106 and its associated conductors 115, 118. The bottom shield 109 may extend upward from the printed circuit board 103 to create three sidewalls on either side of the conductors 115, 118.

[0059] In some embodiments, the printed circuit board 103 can operate as a paddle card, where signals communicating on signal conductors 115 can be processed and transmitted via conductive pads 125 at one end of the substrate of the printed circuit board 103. The paddle card configuration allows signals to be routed and processed within a compact, high-speed cable assembly 100.

[0060] The conductive pad 125 at the end of the printed circuit board 103 can serve as an interface for connecting component 100 to other components or systems. This layout allows the printed circuit board 103 to function as both an end point for the biaxial cable 106 and a signal processing device. The board can thus contain various circuit elements (such as amplifiers, equalizers, or other signal conditioning devices) to optimize signal quality before transmission through the conductive pad 125. Additionally, the board provides flexibility in system integration, allowing the high-speed cable assembly 100 to be easily inserted into or removed from a large electronic system or device.

[0061] also, Figure 3 The conductive termination pads 127 of the printed circuit board 103 are shown. Signal conductor 115 and ground conductor 118 emerge from the biaxial cable 106 and connect to their respective conductive termination pads 127 on the printed circuit board 103. The U-shaped bottom shield 109 may be designed to accommodate the geometry of the terminations of conductors 115, 118 to provide optimal shielding while allowing proper electrical connection.

[0062] In some embodiments, the bottom shield 109 includes a sheet 130 or extension 133 formed on one or more walls of the bottom shield 109, the sheet 130 or extension 133 facilitating attachment of the bottom shield 109 to the top shield 112 or electrical connection of the bottom shield 109 to other shielding members. The precise dimensions and shape of the U-shaped bottom shield 109 can be tailored to specific requirements of the high-speed cable assembly 100 considering factors such as signal frequency, cable size, and overall assembly geometry. Although various embodiments provide a biaxial cable 106 with a standard 24-size (e.g., 24 AWG) dimension, it is understood that other cable sizes and types can also be used.

[0063] In some embodiments, a retaining strip 136 can be located on a printed circuit board 103 to hold an array of bottom shields 109 in a high-speed cable assembly 100. The retaining strip 136 can be designed to hold multiple bottom shields 109 (e.g., such as...). Figure 3 The four bottom shields 109 shown are arranged in a precise layout to ensure proper spacing and alignment of the multiple bottom shields 109 with respect to the corresponding biaxial cables 106. This layout provides consistent shielding performance throughout the cable assembly, improves overall signal integrity, and reduces electromagnetic interference between the terminations of adjacent cables.

[0064] In various embodiments, the retaining strip 136 may be formed of a non-conductive polymer material, which helps the retaining strip 136 maintain electrical isolation between the respective bottom shields 109. Simultaneously, the polymer material provides structural integrity to the array of bottom shields 109, helping to maintain the multiple bottom shields 109 in their intended positions even under mechanical stress or vibration. In some embodiments, the retaining strip 136 includes positioning features corresponding to those features of the top shield 112 to further facilitate the connection of the top shield 112 to the array of bottom shields 109.

[0065] In some embodiments, the retaining strip 136 can be injection molded. For this purpose, the grounding shield 109 may include one or more through-holes 140 located on various surfaces of the grounding shield 109 (including, but not limited to, the walls of the grounding shield 109). Figure 4 During overmolding, the molten polymer material forming the retaining strip 136 can flow through the perforations 140 to create a mechanical interlock as the material hardens or solidifies on both sides of the grounding shield 109. This securely connects the retaining strip 136, formed of a polymer material, to the grounding shield 109, formed of a generally rigid conductive material, enhancing structural integrity by physically anchoring the polymer in place via the perforations 140, without the need for fasteners or adhesives.

[0066] continue, Figure 4 A cross-sectional perspective view is shown of a single biaxial cable 106 terminated in a printed circuit board 103. The printed circuit board 103 is formed of multiple individual layers, which together constitute the printed circuit board 103 or a part of the printed circuit board 103. The multiple individual layers are not necessarily shown to scale, and the thickness of each layer may be highlighted for illustrative purposes.

[0067] Printed circuit board 103 in Figure 4 The diagram illustrates a PCB assembly consisting of multiple PCB layers 139 (e.g., twelve or other numbers), each PCB layer 139 having a unique geometry. Thus, each PCB layer 139 serves a specific purpose in relation to the overall functionality of the high-speed cable assembly 100. For example, the multiple PCB layers 139 may include signal layers, ground planes, power planes, and insulating layers, and may include various notches, windows, vias, etc. The layout and composition of the multiple PCB layers 139 can be optimized to support high-frequency signal transmission and routing, and to minimize electromagnetic interference.

[0068] like Figure 4 and Figure 5As shown, at the top of the printed circuit board 103 is a conductive PCB layer 139a or a portion thereof. PCB layer 139a may include a top layer with conductive traces formed to accommodate conductive pads 127 or other conductive portions of conductors 115, 118 from the biaxial cable 106. The geometry and material composition of these conductive pads 127 may be configured to ensure proper electrical connection and signal integrity at high frequencies involving the operation of component 100. For example, the conductive pad 127 corresponding to the signal conductor 115 may be configured such that PCB layer 139a has an extension arm 142 that engages with a via to electrically connect the conductive pad 127 to another layer of the printed circuit board 103 for routing signals to appropriate portions of the printed circuit board 103.

[0069] Refer again Figure 4 The high-speed cable assembly 100 may include a conductive material 145 on an exposed portion of the biaxial cable 106, such as a biaxial foil 121 exposed through a notched area. The exposed portion of the biaxial foil 121 may be created by various methods to allow electrical connection to other components of the assembly 100. In some embodiments, a portion of the cable sheath 124 may be cut away or notched to expose the underlying biaxial foil 121. Alternatively, the biaxial cable 106 may have a pre-formed exposed portion of the biaxial foil 121 at a location corresponding to the positioning conductive material 145.

[0070] The conductive material 145 can serve as an interface between the exposed biaxial foil 121 and other conductive elements of the assembly 100, such as the top shield 112. The conductive material 145 can take various forms to enhance conductivity and ensure a reliable electrical connection. In some embodiments, the conductive material 145 can be a conductive foam or a conductive thermal paste, which can conform to surface irregularities and provide consistent contact pressure.

[0071] The selection of the conductive material 145 can depend on various factors, such as the specific electrical requirements of the assembly 100, environmental conditions, and manufacturing considerations. Other conductive materials that can be used include conductive adhesives, metal-impregnated elastomers, or specialized conductive compounds. Applying the conductive material 145 to the exposed biaxial foil 121 can help increase the overall conductivity between the biaxial cable 106 and other shielding components, improve signal integrity, and reduce electromagnetic interference in the high-speed cable assembly 100.

[0072] Turn now Figure 6 , Figure 6A top view shows a biaxial cable 106 and its conductors 115, 118 terminated on a printed circuit board 103. The biaxial cable 106 terminates on the printed circuit board 103, wherein the respective signal conductor 115 and ground conductor 118 of the biaxial cable 106 contact conductive pads 127 on the board surface. A retaining strip 136 includes a plurality of U-shaped notches 148 sized and positioned to accommodate various bottom shields 109 in an array.

[0073] The U-shaped notch 148 can be precisely dimensionally matched to the shape of the bottom shield 109 to allow for a snug fit that helps maintain the position and alignment of each bottom shield 109. The retaining strip 136, together with its plurality of U-shaped notches 148, provides structural support to the plurality of bottom shields 109, ensuring consistent spacing between adjacent bottom shields 109 and assisting the assembly process by guiding the placement of the bottom shields 109.

[0074] Next, refer to Figure 7 , Figure 7 A top view of a printed circuit board 103 is shown, comprising arrays 150a and 150b with two bottom shields 109 and two corresponding retaining strips 136. For illustrative purposes, the biaxial cable 106 and associated components are omitted. The configuration of the printed circuit board 103 and the arrays 150 with the two bottom shields 109 can accommodate two rows of biaxial cables 106, but a single row or more can also be used. Each array 150 of the bottom shields 109 can be held in place by a retaining strip 136, which can be located on the printed circuit board 103.

[0075] The retaining strip 136 may be characterized by a plurality of U-shaped notches designed to accommodate and align the respective bottom shields 109 in the array 150 of the respective bottom shields 109. This arrangement provides structural support and maintains precise spacing between adjacent shields 109 within each row. The dual-array configuration allows for increased cable density in the high-speed cable assembly 100 and potentially enhances overall shielding effectiveness. The bottom shields 109 in each array 150 may be aligned with corresponding conductive termination pads 127 on the printed circuit board 103, which facilitates proper termination of the biaxial cable 106 when it is installed.

[0076] Although an array 150 of the two bottom shields 109 is shown, it is understood that in some embodiments, a single array 150 may be used. In alternative embodiments, depending on the required number of cables 106, three or more arrays 150 may be used. The number of arrays 150 can be adjusted to accommodate various cable densities and configurations. For example, a single array 150 may be suitable for applications with fewer requirements for biaxial cables 106, while multiple arrays 150 can be implemented in high-density designs where a larger number of cables 106 require termination. The flexibility in the number of arrays 150 allows the high-speed cable assembly 100 to be adapted to different system requirements and space constraints. Each additional array 150 may be accompanied by its own retaining strip 136 to maintain the structural integrity and precise alignment of the multiple bottom shields 109 across all rows of biaxial cables 106.

[0077] A side view of the printed circuit board 103 is shown. Figure 8 This shows a bottom shield 109 and a retaining strip 136. See also... Figure 7 and Figure 8 The bottom shield 109 may include a piece 130 and an extension 133 protruding from the wall of the bottom shield 109. The piece 130 and the extension 133 may be provided within the assembly 100 at points for electrical connection or mechanical attachment to the top shield 112.

[0078] Furthermore, the printed circuit board 103 may include a trough 153 designed to accommodate the biaxial cable 106. For example, the trough 153 may allow the biaxial cable 106 to be partially embedded within a surface of the printed circuit board 103, which helps to reduce the overall form factor and overall height of the component 100. Additionally, the trough 153 may aid in the precise positioning and alignment of the biaxial cable 106 relative to its termination points on the printed circuit board 103. By slightly recessing the biaxial cable 106 into the surface of the printed circuit board 103, the component 100 is better able to withstand mechanical stresses or vibrations that would otherwise affect the integrity of the cable termination.

[0079] Figure 9 A perspective view of a representative biaxial cable 106 is shown, while Figure 10 Provide a top view of the same dual-axis cable 106. Refer to the references below. Figure 9 and Figure 10The biaxial cable 106 includes two signal conductors 115, two ground conductors 118, and a notched area 156 on the sheath 124 exposing the biaxial foil 121. The two signal conductors 115 may be bent downwards and / or outwards relative to each other, creating a minimum desired distance between them. In some embodiments, this minimum desired distance is 0.35 mm to 0.49 mm, but other dimensions are also possible. This improves signal integrity by reducing electromagnetic coupling between the two signal conductors 115. Similarly, the two ground conductors 118 may be bent downwards and / or outwards relative to each other.

[0080] Thus, each of conductors 115 and 118 can include one or more bends. The bends on the signal conductor 115 and the ground conductor 118 can be precisely formed to achieve specific impedance characteristics and maintain electrical consistency. The angle and extent of the bend can be adapted to the specific requirements of the high-speed cable assembly 100, such as signal frequency, desired impedance characteristics, and the overall geometry of the assembly. In some embodiments, the signal conductor 115 may extend beyond the sheath 124 by a predetermined distance (e.g., about 0.1 mm, 0.2 mm, etc.) before a bend occurs to maintain precise positional control of the signal conductor 115.

[0081] A notch region 156 on the sheath 124 may be located to expose a portion of the biaxial foil 121, which is typically present between the sheath 124 and conductors 115, 118. The exposed portion of the biaxial foil 121 facilitates electrical connection with other components of the assembly 100, including but not limited to conductive material 145 or top shield 112. The size and shape of the notch region 156 may be optimized as needed to provide sufficient exposure of the biaxial foil 121 and may optionally be configured to ensure that the structural integrity of the biaxial cable 106 is maintained in a suitable manner. For example, in the illustrated embodiment, the notch region 156 is rectangular and does not extend through the end of the sheath 124, but many other configurations are also possible. The exposed biaxial foil 121 in the notch region 156 may be treated or prepared to enhance the conductivity or adhesion properties of the biaxial foil 121. This preparation may involve cleaning, surface roughening, or applying a conductive coating to ensure optimal electrical contact with other conductive elements in the assembly 100.

[0082] Figure 11A and Figure 11B The diagram shows a bottom perspective view of the top shield 112, while... Figure 12 and Figure 13 Top and bottom views of the top shield 112 are provided. The body of the top shield 112 includes various bends that form multiple stepped regions 159 defining multiple channels 162. These channels 162 may be designed to accommodate a sheath 124 of a biaxial cable 106 or other portions of the biaxial cable 106.

[0083] Conductive material 145 can be located on the bottom surface of the top shield 112 (including within the channel 162). Thus, when assembly 100 is formed, conductive material 145 can align with the notch area 156 of cable 106 and the exposed biaxial foil 121. Therefore, as will be appreciated, conductive material 145 can be located at desired locations using various manufacturing processes, such as, but not limited to, placing conductive material 145 on cable 106 or on top shield 112. Although multiple individual sheets are shown, it is also feasible to extend conductive material around multiple biaxial cables 106. Furthermore, multiple bends on top shield 112 allow top shield 112 to tightly surround the termination area of ​​each biaxial cable 106. The tight-fitting nature of top shield 112 provides additional grounding capability to assembly 100. For example, the proximity of conductive top shield 112 to cable terminations helps manage electromagnetic interference and improve signal integrity. As can be recognized, the top shield 112 may be made of a generally rigid conductive material, such as a metal or a metallized polymer.

[0084] Reference Figure 11A , Figure 12 and Figure 13 The body of the top shield 112 may include one or more notches 165 that intersect with a plate 130 on the bottom shield 109 to form a mechanical connection with the bottom shield 109 in the array 150. Thus, the notches 165 can be precisely positioned and sized to correspond to the plate 130 on the bottom shield 109 to allow a fixed fit when the top shield 112 is assembled on the array 150. The interaction between the notches 165 and the plate 130 provides stability to the overall assembly 100 and maintains proper alignment and electrical continuity between the top shield 112 and the bottom shield 109. In some embodiments, the notches 165 may be designed to create a snap-fit ​​or friction-fit connection with the plate 130, which simplifies assembly and reduces the need for additional fasteners. Alternatively, in some embodiments, the notch 165 serves as a location for welding or soldering the sheet 130 to the top shield 112. Welding may include laser welding, which provides precise and localized heat to create a connection between the sheet 130 and the top shield 112. Alternatively, the top shield 112 may not include any notch 165, such as... Figure 11B As shown. In this embodiment, in the absence of sheet 130 or similar components, the top shield 112 may be attached to one or more of the plurality of bottom shields 109 by welding or other means.

[0085] Now refer to Figure 14 and Figure 15 , Figure 14This is a rear top-view perspective view of component 100, and Figure 15 This is a rear view of component 100. See also: Figure 14 and Figure 15 In various embodiments, component 100 may further include a stabilizing bar 168. The stabilizing bar 168 may include a single, integral body positioned between the top shield 112 and the remainder of the bodies of the plurality of individual biaxial cables 106. The stabilizing bar 168 may extend laterally across the printed circuit board 103 parallel to the array of top shield 112 and bottom shield 109. Thus, the stabilizing bar 168 can extend across the plurality of biaxial cables 106, providing support and maintaining alignment of the plurality of cables 106 near their termination points on the printed circuit board 103. In some embodiments, the stabilizing bar 168 is positioned parallel to and in contact with the retaining bar 136.

[0086] In some embodiments, the stabilizing strip 168 may be overmolded, allowing it to conform closely to the contours of the plurality of biaxial cables 106 and the top shield 112, creating a fit. In any case, the stabilizing strip 168 may be configured to provide strain relief near the termination areas of the plurality of cables 106. By supporting the plurality of cables 106 near their junctions, the stabilizing strip 168 helps absorb and disperse external forces that might otherwise be transmitted directly to the terminations. The stabilizing strip 168 may also include a plurality of channels having cross-sections that conform closely to the cross-sections of the plurality of individual biaxial cables 106 to enhance cable alignment and separation.

[0087] Reference Figure 16 and Figure 17 , and these Figure 1 and Figure 2 Similar embodiments are shown to the examples illustrated. However, with Figure 1 and Figure 2 Compared to other embodiments, each wall of the bottom shield 109 may include one or more protrusions 170, which are rabbit-ear shaped in the illustrated embodiment. For example, each protrusion 170 may include two elongated parts inclined in opposite directions. The protrusions 170 may be designed to be slightly flexed or deformed for insertion into a recess 165 of the top shield 112. When positioned in the recess 165, the protrusions 170 return to their undeformed state and help bias the bottom shield 109 and the top shield 112 together and / or create an interference fit between the bottom shield 109 and the top shield 112.

[0088] The protrusion 170 may extend outward from the wall of the bottom shield 109 and may be shaped to correspond in size and geometry to the recess 165 on the top shield 112. During assembly, the protrusion 170 may engage with the recess 165 to provide a fixed mechanical connection between the bottom shield 109 and the top shield 112 without additional fastening methods (such as soldering or fusion welding). The protrusion 170 simplifies the assembly process by allowing a quick and tool-free connection between the bottom shield 109 and the top shield 112. The interference fit also provides flexibility in the connection, allowing for slight adjustments or realignment during assembly while maintaining a fixed connection. In some embodiments, the protrusion 170 is integral with the bottom shield 109. The protrusion 170 may be sized and positioned to provide a balance between ease of insertion and the strength of the resulting connection.

[0089] Refer to together Figures 18 to 22 , Figure 18 This is a top perspective view of a high-speed cable assembly 100 characterized by a grounding shield 179 and a holding device 173 according to various embodiments of the present disclosure. Figure 19 This is a top-view perspective view of a high-speed cable assembly 100, in which the grounding shield 179 is omitted, and Figures 20 to 22 These are various views of the high-speed cable assembly 100, wherein, for illustrative purposes, the grounding shield 179 and the retaining device 173 are omitted. For illustrative purposes, Figure 21 and Figure 22 The grounding conductor 118 is also omitted from the view.

[0090] According to various embodiments, the retaining device 173 can be formed of a resin (such as a liquid crystal polymer (LCP)) or other non-conductive material. The retaining device 173 can be designed to hold or otherwise maintain the signal conductor 115 and / or the ground conductor 118 relative to a ground shield 179. For example, in some embodiments, the retaining device 173 can hold or maintain crimp tubes 176a, 176b (collectively, “crimp tube 176”) and / or conductor 118 surrounding one or more conductors 115. In one embodiment, the crimp tube 176 can be formed of a conductive material (such as a plated plastic, a conductive plastic, or a metal alloy) and can be soldered, welded, or conductively bonded to the conductor 115. For this purpose, the retaining device 173 can be sized and positioned to hold the crimp tube 176 relative to the ground shield 179, which can be made of metal or other conductive material. This arrangement helps ensure consistent grounding and shielding performance across the termination of a biaxial cable 106.

[0091] The retaining device 173 may include a front end 181, a rear end 182, and side walls 183a, 183b (collectively, “side walls 183”) extending between the front end 181 and the rear end 182. The rear end 182 may include a through-hole for accommodating each signal conductor 115. For example, if there are two signal conductors 115, there may be two through-holes on the rear end 182, and so on. The front end 181 may, for example, slope downwards from a position near the rear end 182 to a position away from the rear end 182, such as... Figure 19 As shown.

[0092] Similarly, the grounding shield 179 may include a front end 184, a rear end 185, and side walls 186a, 186b (collectively, “side walls 186”) extending between the front end 184 and the rear end 185. The rear end 182 may include a through-hole accommodating each signal conductor 115. For example, if there are two signal conductors 115, there may be two through-holes on the rear end 185. The front end 184 may be tilted from a position close to the rear end 185 to a position away from the rear end 185, such as… Figure 20 As shown. The grounding shield 179 may also include a window 187 for observing or accessing the pressure pipe 176, the signal conductor 115, and / or the grounding conductor 118.

[0093] In some embodiments, the grounding conductor 118 extends into and contacts the grounding shield 179 to provide shielding between the biaxial cable 106 and the grounding shield 179. Thus, the grounding shield 179 provides electromagnetic shielding and serves as a structural support for the compression fitting 176 and associated conductors 115, 118. The retaining device 173 may intersect with the grounding shield 179 in a manner that allows for secure attachment while maintaining electrical isolation between conductive and non-conductive retaining devices 173. In some embodiments, the grounding shield 179 and the retaining device 173 are in the form of a snap-fit ​​or interference connection. Figures 18 to 20 Various PCB layers in multiple PCB layers 139 stacked within the high-speed cable assembly 100 are also shown.

[0094] The plurality of PCB layers 139 may include features that complement the retaining device 173 and the grounding shield 179. For example, certain layers of the printed circuit board 103 may include pads or traces specifically designed to intersect with the crimp tube 176 or the grounding shield 179. In some embodiments, the printed circuit board 103 may include a dedicated PCB layer 139 directly connected to the grounding shield 179 to enhance the overall shielding effect of the component 100. Figure 20 As shown, the crimp connector 176 has a first portion that extends laterally along the signal conductor 115 and then extends downward at an angle to contact a top surface of the printed circuit board 103.

[0095] continue, Figure 23 This is a top perspective view of a high-speed cable assembly 100 characterized by a grounding shield 179 and a holding device 173 according to various embodiments of the present disclosure. Figure 24 This is a side view of component 100, in which the grounding shield 179 is omitted. Figure 25 It is a three-dimensional diagram in which, for illustrative purposes, the grounding shield 179 and the holding device 183 are omitted, and Figure 26 This is a top view, in which, for explanation purposes, grounding shield 179 is omitted. Furthermore, Figure 27 For a side view and Figure 28 This is a top view, in which, for illustrative purposes, the grounding shield 179 and the holding device 183 are omitted.

[0096] Refer to together Figures 23 to 28 The grounding shield 179 includes a front end 184 and two L-shaped sidewalls 186a, 186b, each having a protrusion extending along a rear end of the grounding shield 179. The rear end 185 does not include a continuous wall with perforations. Instead, the rear end 185 includes a channel defined by the two L-shaped sidewalls 186, accommodating two signal conductors 115. In some embodiments, the two ground conductors 118 may extend into the perforations on the sidewalls 186, or may be located within the channel. The grounding shield 179 may also include a window 187 that allows observation or access to the pressure pipe 176, the signal conductors 115, and / or the ground conductors 118.

[0097] The retaining device 173 may include an integral cuboid portion 188 and a vertical extension 189. The cuboid portion 188 and / or the vertical extension 189 may define two signal conductors 115 that may be located in one or more through-holes 192 passing through them. Figure 27 and Figure 28 The retaining device 173 is omitted, so that the position of the crimp tube 176 and signal conductor 115 terminated on the printed circuit board 103 can be seen.

[0098] Turn now Figures 29 to 32 , Figures 29 to 32 Another embodiment of a grounding shield 179 and a holding device 173 is shown. Figure 29 This is a top perspective view of a cable assembly 100 having a grounding shield 179 and a holding device 173 according to various embodiments. Figure 30 This is a side view of the cable assembly 100, and Figure 31 This is a top view of the cable assembly 100. Figure 32 A front perspective view of component 100 is shown, with the grounding shield 179 and the retaining device 173 omitted for illustrative purposes.

[0099] Refer to together Figures 29 to 32 The grounding shield 179 includes a U-shaped body having a front end 184 and two sides 186a, 186b extending from their respective sides of the front end 184. The two sides 186 together define a channel in which two signal conductors 115 and / or two crimp connectors 176 are located and terminated to the printed circuit board 103. The retaining device 173 includes a U-shaped body having an upwardly projecting first vertical side, an upwardly projecting second vertical side, and a transverse portion connecting the first and second vertical sides. The transverse portion may be located on a top surface of the printed circuit board 103 and may support the two signal conductors 115 and / or the two crimp connectors 176. The width of the retaining device 173 may be the same as or substantially similar to the width of the channel defined by the two sides 186a, 186b to facilitate a fitted arrangement of the two components.

[0100] like Figure 32 As shown, the crimp connector 176 can extend laterally relative to the signal conductor 115 in a common direction and can include a crimped portion with a semi-circular cross-section. Furthermore, the crimp connector 176 includes a standoff portion 190 that extends vertically and electrically connects the crimp connector 176 and the signal conductor 115 to the printed circuit board 103 or a similar substrate. The standoff portion 190 can include a base having a width wider than a middle portion, wherein the middle portion terminates in the semi-circular cross-sectional portion of the crimp connector 176. It should be noted that in some figures, the retaining device 173 is shown as a wall, but it can also be configured more similarly... Figure 19 The holding device 173 shown.

[0101] continue, Figures 33 to 35 Another embodiment of a grounding shield 179 and a holding device 173 is shown. Figure 33 This is a top perspective view of a cable assembly 100 having a grounding shield 179 and a holding device 173 according to various embodiments. Figure 34 This is a top view of cable assembly 100, and Figure 35 This is a side view of the cable assembly 100.

[0102] Refer to together Figures 33 to 35The retaining device 173 includes a generally rectangular, single, integral body portion located perpendicular to a longitudinal axis of the sheath 124 of the biaxial cable 106 and / or the printed circuit board 103. A bottom of the retaining device 173 is located on a top surface of the printed circuit board 103. The retaining device 173 includes a U-shaped notch accommodating each signal conductor 115 and / or crimp tube 176. If present, the U-shaped notch may have an inner diameter that closely conforms to an outer diameter of the signal conductor 115 or crimp tube 176. Thus, when the signal conductor 115 exits from the sheath 124 of the biaxial cable 106, the retaining device 173 can support the signal conductor 115 to provide support for strain at a suitable location.

[0103] Next, Figures 36 to 37 Another embodiment of a grounding shield 179 and a holding device 173 is shown. Figure 36 This is a top perspective view of a cable assembly 100 having a grounding shield 179 and a holding device 173 according to various embodiments, and Figure 37 This is a top view of cable assembly 100. (See also:) Figures 36 to 37 The holding device 173 is similar to Figures 33 to 35 The retaining device 173. However, the retaining device 173 also includes a lateral support 191 extending vertically from a central portion of the retaining device 173. The retaining device 173 also includes a U-shaped recess for receiving each signal conductor 115 and / or crimp tube 176.

[0104] Turn now Figure 38 This illustrates various embodiments. Figures 1 to 4 Another embodiment of the bottom shield 109. In Figure 38 In this embodiment, signal conductor 115 does not include crimp connector 176; however, it is understood that crimp connector 176 may also be used in some embodiments. Signal conductor 115 may include a downward bend that extends from a central portion of a plane of sheath 124 to electrically connect to printed circuit board 103. Signal conductor 115 may be cut, stamped, or crimped at the portion contacting printed circuit board 103 and may be soldered, welded, or otherwise permanently attached to printed circuit board 103.

[0105] In some embodiments, component 100 includes a retaining device 192 that can be formed of a non-conductive material, such as LCP or other suitable polymer. The retaining device 192 can be part of another retaining device 173 located in component 100 or other non-conductive portions of component 100. A body of the retaining device 192 can include a wedge-shaped bottom 193, a neck 194, and a protrusion 195. The wedge-shaped bottom 193 of the retaining device 192 can generally be triangular and can have two tapering edges such that the width of the lower portion of the wedge-shaped bottom 192 (e.g., between signal conductors 115) is less than the width of the upper portion of the wedge-shaped bottom 192 connected to the neck 194 (e.g., above the signal conductors 115). As will be appreciated, the wedge-shaped bottom 192 can be located between a pair of signal conductors 115 to prevent signal interference between the two bodies of the signal conductors 115.

[0106] The neck 194 can be located in a notch or perforation in another component of assembly 100 (e.g., a non-conductive structural support component, a non-conductive housing portion, etc.) for illustrative purposes. The protrusion 195 can provide an interference connection with other components, wherein the neck 194 is held in the notch or perforation, and wherein the protrusion 195 prevents the neck 194 from disengaging by means of its shape and size relative to the neck 194.

[0107] Although the various embodiments described herein depict biaxial cable 106, it is understood that the disclosed principles and techniques can be applied or employed with other types of cables. For example, high-speed cable assembly 100 may comprise coaxial cable, twisted-pair cable, fiber optic cable, or multi-conductor cable. In some embodiments, assembly 100 may employ shielded twisted-pair cable, unshielded twisted-pair cable, or four-core cable. The shielding and termination techniques described are also applicable to use with ribbon cable, flat flexible cable, or miniature coaxial cable. Additionally, assembly 100 may be configured to accommodate hybrid cables (such as those used in audio / video applications or specialized industrial equipment) that combine multiple cable types within a single sheath.
