Technical Field

[0001] This application relates to signal transmission technology, and more specifically, to a shielded differential cable that can be used for high-speed signal transmission. Background Technology

[0002] Differential harnesses have anti-interference characteristics and can be used for high-speed signal transmission. In recent years, the development of AI technology has led to the need for a large number of high-speed signals to be transmitted in electronic devices such as servers, resulting in a surge in demand for differential harnesses in such electronic devices. Therefore, existing electronic devices usually contain multiple differential harnesses that can transmit high-speed signals. It should be noted that with the thinner and lighter design of electronic devices, the internal space of electronic devices has been greatly reduced and the number of differential harnesses used has increased. As a result, it is time-consuming and error-prone to wiring, aligning, and connecting the differential harnesses in the internal space of electronic devices.

[0052] In this application Figures 1 to 8In the illustrated embodiment, at least one shielded differential cable 1 is disclosed, the shielded differential cable 1 comprising: at least one top surface tape 111, at least one bottom surface tape 112, at least one first shielded differential cable bundle 121 and at least one second shielded differential cable bundle 122.

[0053] The first shielded differential harness 121 comprises a pair of first shielded differential harness signal lines 1211 and 1212, an inner insulating layer 1213, a metal shielding layer 1214, and an outer insulating layer 1215. The pair of first shielded differential harness signal lines 1211 and 1212 can transmit signals of equal magnitude but opposite polarity. The inner insulating layer 1213 can be formed of insulating materials such as PE (Polyethylene) or Teflon (Polytetrafluoroethylene), and covers the pair of first shielded differential harness signal lines 1211 and 1212 to provide impedance matching for signal transmission. The first shielded differential harness metal shielding layer 1214 covers the first shielded differential harness inner insulation layer 1213 to provide shielding for the signal transmission of the first shielded differential harness signal lines 1211 and 1212, thereby reducing the high-speed signal transmission loss of the first shielded differential harness signal lines 1211 and 1212. The first shielded differential harness outer insulation layer 1215 may be formed by winding insulating materials such as PET (Polyethylene terephthalate). The first shielded differential harness outer insulation layer 1215 covers the first shielded differential harness metal shielding layer 1214 to provide shape for the first shielded differential harness metal shielding layer 1214. The top surface and bottom surface of the first shielded differential harness outer insulation layer 1215 are respectively a first shielded differential harness adhesive top surface F12151 and a first shielded differential harness adhesive bottom surface F12152.

[0054] The second shielded differential harness 122 comprises a pair of second shielded differential harness signal lines 1221 and 1222, an inner insulating layer 1223, a metal shielding layer 1224, and an outer insulating layer 1225. The pair of second shielded differential harness signal lines 1221 and 1222 can transmit signals of equal magnitude but opposite polarity. The inner insulating layer 1223 can be formed of insulating materials such as PE (Polyethylene) or Teflon (Polytetrafluoroethylene), and covers the pair of second shielded differential harness signal lines 1221 and 1222 to provide impedance matching for the signal transmission of the pair of second shielded differential harness signal lines 1221 and 1222. The second shielded differential harness metal shielding layer 1224 covers the second shielded differential harness inner insulation layer 1223 to provide shielding for the signal transmission of the second shielded differential harness signal lines 1221 and 1222, thereby reducing the high-speed signal transmission loss of the second shielded differential harness signal lines 1221 and 1222. The second shielded differential harness outer insulation layer 1225 may be formed by winding insulating materials such as PET (Polyethylene terephthalate). The second shielded differential harness outer insulation layer 1225 covers the second shielded differential harness metal shielding layer 1224 to provide shape for the second shielded differential harness metal shielding layer 1224. The top surface and bottom surface of the second shielded differential harness outer insulation layer 1225 are respectively a second shielded differential harness adhesive top surface F12251 and a second shielded differential harness adhesive bottom surface F12252.

[0055] The top adhesive tape 111 has a top adhesive tape base layer 1111 and a top adhesive material layer 1113. The top adhesive material layer 1113 provides adhesion for the first shielded differential wiring harness adhesive top surface F12151 and the second shielded differential wiring harness adhesive top surface F12251. The top adhesive tape base layer 1111 provides support for the top adhesive material layer 1113. The top adhesive tape base layer 1111 may be formed of a PI (Polyimide) plastic material, and the top adhesive tape base layer 1111 may have a porous structure to provide heat dissipation.

[0056] The bottom adhesive tape 112 has a bottom adhesive tape base layer 1121 and a bottom adhesive material layer 1123. The bottom adhesive material layer 1123 provides adhesion for the first shielded differential wiring harness adhesive bottom surface F12152 and the second shielded differential wiring harness adhesive bottom surface F12252. The bottom adhesive tape base layer 1121 provides support for the bottom adhesive material layer 1123. The bottom adhesive tape base layer 1121 may be formed of a PI (Polyimide) plastic material, and the bottom adhesive tape base layer 1121 may have a porous structure to provide heat dissipation.

[0057] It should be noted that the outer insulation layer 1215 of the first shielded differential harness is adjacent to the outer insulation layer 1215 of the second shielded differential harness, and the thicknesses of the first shielded differential harness 121 and the second shielded differential harness 122 are substantially equal, so that the heights of the first shielded differential harness adhesive top surface F12151 and the second shielded differential harness adhesive top surface F12251 are substantially equal. That is, the first shielded differential harness adhesive top surface F12151 and the second shielded differential harness adhesive top surface F12251 can be on a plane with substantially equal heights, and the heights of the first shielded differential harness adhesive bottom surface F12152 and the second shielded differential harness adhesive bottom surface F12252 are substantially equal. That is, the first shielded differential harness adhesive bottom surface F12152 and the second shielded differential harness adhesive bottom surface F12252 are substantially equal. The first shielded differential harness adhesive surface F12152 and the second shielded differential harness adhesive surface F12252 can be on a plane with substantially equal height. Thus, the top adhesive tape 111 can be substantially flatly adhered to the first shielded differential harness adhesive surface F12151 and the second shielded differential harness adhesive surface F12251 to position the first shielded differential harness 121 and the second shielded differential harness 122. Similarly, the bottom adhesive tape 112 can be substantially flatly adhered to the first shielded differential harness adhesive surface F12152 and the second shielded differential harness adhesive surface F12252 to position the first shielded differential harness 121 and the second shielded differential harness 122.

[0058] It should be noted that after the top adhesive tape 111 and the bottom adhesive tape 112 are used to attach the first shielded differential cable harness 121 and the second shielded differential cable harness 122, the top adhesive tape 111, the bottom adhesive tape 112, the first shielded differential cable harness 121 and the second shielded differential cable harness 122 will become a flat ribbon cable similar to an FPC (Flexible Printed Circuit), which makes it easy to align, organize and connect the first shielded differential cable harness 121 and the second shielded differential cable harness 122 in the limited space inside the electronic device.

[0059] In this application Figures 5 to 8 In the illustrated embodiment, the top adhesive tape 111 further comprises a top metal material layer 1112, wherein the top adhesive tape base layer 1111 also provides support for the top metal material layer 1112, which provides shielding to reduce high-speed signal transmission loss to the second shielded differential harness signal lines 1221 and 1222. The bottom adhesive tape 112 further comprises a bottom metal material layer 1122, wherein the bottom adhesive tape base layer 1121 also provides support for the bottom metal material layer 1122, which provides shielding to reduce high-speed signal transmission loss to the second shielded differential harness signal lines 1221 and 1222.

[0060] It should be noted that, in this application, at least one of the top surface metal material layer 1112 and the bottom surface metal material layer 1122 may be omitted.

[0061] In this application Figure 4 and Figure 6In the embodiment shown, the shielded differential cabling 1 further includes a non-differential cable harness 123. The top and bottom surfaces of the non-differential cable harness 123 respectively have a non-differential cable harness adhesive top surface F12321 and a non-differential cable harness adhesive bottom surface F12322. The thickness of the non-differential harness 123 is substantially equal to the thickness of the first shielded differential harness 121 and the second shielded differential harness 122. This ensures that the height of the non-differential harness adhesive top surface F12321 is substantially equal to the height of the first shielded differential harness adhesive top surface F12151 and the second shielded differential harness adhesive top surface F12251, and that the height of the non-differential harness adhesive bottom surface F12322 is substantially equal to the height of the first shielded differential harness adhesive bottom surface F12152 and the second shielded differential harness adhesive bottom surface F12252. This allows the top adhesive tape 111 to be flatly adhered to the non-differential harness adhesive top surface F12321, the first shielded differential harness adhesive top surface F12151, and the... The second shielded differential harness is attached to the top surface F12251, and the bottom adhesive tape 112 is allowed to be flatly attached to the non-differential harness attachment bottom surface F12322, the first shielded differential harness attachment bottom surface F12152, and the second shielded differential harness attachment bottom surface F12252. That is, the top adhesive tape 111 and the bottom adhesive tape 112 are substantially flatly attached to the first shielded differential harness 121, the second shielded differential harness 122, and the non-differential harness 123, making the top adhesive tape 111, the bottom adhesive tape 112, the first shielded differential harness 121, the second shielded differential harness 122, and the non-differential harness 123 resemble an FPC (Flexible Printed Circuit). The flat ribbon cable of the Printed Circuit makes it easy to align, organize and connect the first shielded differential cable bundle 121, the second shielded differential cable bundle 122 and the non-differential cable bundle 123 in the limited space inside the electronic device.

[0062] The non-differential harness 123 also has a non-differential harness signal line 1231 and a non-differential harness outer insulation layer 1232. The non-differential harness outer insulation layer 1232 covers the non-differential harness signal line 1231 to provide shaping for the non-differential harness signal line 1231. The non-differential harness bonding top surface F12321 and the non-differential harness bonding bottom surface F12322 are respectively located on the top and bottom surfaces of the non-differential harness outer insulation layer 1232.

[0063] In this application Figure 6In the illustrated embodiment, the non-differential harness 123 is located between the first shielded differential harness 121 and the second shielded differential harness 122, and the non-differential harness outer insulation layer 1232 is adjacent to the first shielded differential harness outer insulation layer 1215 and the second shielded differential harness outer insulation layer 1225. However, this is not a limitation. In this application, the non-differential harness outer insulation layer 1232 may be adjacent to either the first shielded differential harness outer insulation layer 1215 or the second shielded differential harness outer insulation layer 1225. Therefore, in this application, the non-differential harness outer insulation layer 1232 is adjacent to at least one of the first shielded differential harness outer insulation layer 1215 and the second shielded differential harness outer insulation layer 1225.

[0064] It should be noted that some components may be omitted in the foregoing embodiments of this application. For example, in this application, the shielded differential cable may include: a first shielded differential cable harness, a second shielded differential cable harness, top adhesive tape, and bottom adhesive tape.
