Description

Technical Field

[0001] This utility model relates to the field of high-speed cables, and in particular to a high-speed cable connector. Background Technology

[0002] In today's digital age, the speed and stability of data transmission have become crucial supports for the development of various industries. High-speed cables, as the core connection medium for data transmission, play a pivotal role in cutting-edge fields such as data centers, network infrastructure, cloud computing, artificial intelligence, and autonomous driving. Traditional high-speed cables have relatively short printed circuit boards and large internal space in their metal shells, with the outer sheath / network tube / braided layer only extending inside the shell. However, with the development of copper cable technology, the internal space of the metal shell can no longer meet the requirements for cable exit. Existing high-speed cable connector structures lack sufficient bending space for the wires, easily damaging the core wires and signal transmission performance. If the exit portion is extended outside the metal shell, part of the original wire's shielding braided layer needs to be removed, leading to a deterioration in electromagnetic shielding effectiveness and a reduction in wire strength, shortening lifespan, and even posing safety hazards. Therefore, a high-speed cable connector that is stable to install without damaging the wire, and whose shielding effectiveness and strength meet the requirements, is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model proposes a high-speed cable connector, which has the advantages of stable installation without damaging the cable and good shielding effect.

[0004] To achieve the above objectives, this utility model proposes a high-speed cable connector, which includes: Printed circuit board; high-speed cable, the high-speed cable comprising, from the inside out, a core wire, a high-temperature layer, a conductive layer, and an outer sheath layer, wherein the high-temperature layer covers the core wire, the conductive layer covers the high-temperature layer, the outer sheath layer covers the conductive layer, and the core wire is connected to the printed circuit board to form an electrical path. A connector includes a connector upper cover and a connector lower cover, the connector upper cover and the connector lower cover cooperating to form a housing that encloses the printed circuit board and the high-speed cable connection, wherein the conductive layer extends into the interior of the connector at one end near the printed circuit board.

[0005] Preferably, the outer sheath is shorter than the conductive layer at the end near the printed circuit board. The high-speed cable also includes an insulating layer and a heat-shrinkable layer. The insulating layer covers the connection between the outer sheath and the conductive layer at the end near the printed circuit board, and the heat-shrinkable layer completely covers the insulating layer.

[0006] Preferably, the high-speed cable further includes a filler layer and a shielding braid layer, the filler layer covering the end of the core wire away from the printed circuit board, and the shielding braid layer covering the filler layer.

[0007] Preferably, the end of the high-temperature layer closest to the printed circuit board is shorter than the core wire and flush with the end of the printed circuit board closest to the high-speed cable; the end of the high-temperature layer furthest from the printed circuit board overlaps with the filler layer; and the end of the conductive layer furthest from the printed circuit board overlaps with the shielding braid layer.

[0008] Preferably, the outer layer of the high-speed cable is further provided with a conductive layer, which covers the overlap of the heat-shrinkable layer and the conductive layer, and is located inside the connector and is in contact with the connector for conduction.

[0009] Preferably, the connector further includes a fixing member for connecting the upper cover of the connector and the lower cover of the connector.

[0010] Preferably, the conductivity of the conductive layer is at least 90% of the conductivity of the shielding braid layer.

[0011] Preferably, a pull ring is provided at the end of the connector lower cover away from the printed circuit board.

[0012] This invention features a novel high-speed cable connector that allows for stable installation without damaging the cable. A high-temperature layer covers the core wire, isolating it from the conductive layer and the internal and external grounding paths of the connector to prevent short circuits. The conductive layer replaces the original stripped wire structure, achieving equivalent shielding. Combined with the isolation effect of the high-temperature layer, it avoids the problems of insufficient wiring space, reduced shielding performance, and deteriorated mechanical strength found in existing technologies. The connector's upper and lower covers work together to form a housing, enabling overall assembly and protecting the printed circuit board and high-speed cable. The housing and conductive layer together provide complete electromagnetic shielding. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. If the specific posture changes, the directional indication will also change accordingly.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a high-speed cable connector, including a printed circuit board 1; a high-speed cable 2, the high-speed cable 2 including, from the inside out, a core wire 21, a high-temperature layer 24, a conductive layer 25, and an outer sheath layer 26, wherein the high-temperature layer 24 covers the core wire 21, the conductive layer 25 covers the high-temperature layer 24, and the outer sheath layer 26 covers the conductive layer 25. The core wire 21 is connected to the printed circuit board 1 to form an electrical path, and Connector 3 includes connector upper cover 32 and connector lower cover 31. Connector upper cover 32 and connector lower cover 31 cooperate to form a housing that encloses the connection between printed circuit board 1 and high-speed cable 2. The conductive layer 25 extends into the interior of connector 3 at one end near printed circuit board 1.

[0020] In this embodiment, as Figure 1 and Figure 2As shown, by setting up a new type of high-speed cable connector, stable installation can be achieved without damaging the cable. The high-temperature layer 24 covers the core wire 21 to isolate the core wire 21 from the conductive layer 25 and isolate the internal and external grounding paths of the connector 3 to avoid short circuits. The conductive layer 25 replaces the original structure after the wire is stripped, thereby achieving equivalent shielding. Combined with the isolation effect of the high-temperature layer 24, the problems of insufficient wiring space, reduced shielding performance, and deterioration of mechanical strength in the prior art are avoided. The connector upper cover 32 and the connector lower cover 31 cooperate to form a box, realizing overall assembly, thereby protecting the printed circuit board 1 and the high-speed cable 2. The box and the conductive layer 25 together achieve complete electromagnetic shielding.

[0021] In actual implementation, during the assembly process of the high-speed cable 2, the outer sheath and other structures at the ends of the wire are stripped off to expose multiple core wires 21. The exposed length of the core wires 21 is preferably 5~100mm.

[0022] In actual implementation, the preferred connection method between the printed circuit board 1 and the core wire 21 is soldering. Multiple core wires 21 can be soldered to one side of the printed circuit board 1 or to the upper and lower sides of the printed circuit board 1 respectively, depending on actual needs. The solder joint is covered with UV curing adhesive 11.

[0023] In actual implementation, the outer sheath 26 is preferably a PET mesh tube.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the outer sheath 26 is shorter than the conductive layer 25 at the end near the printed circuit board 1. The high-speed cable 2 also includes an insulating layer 27 and a heat-shrinkable layer 28. The insulating layer 27 covers the connection between the outer sheath 26 and the conductive layer 25 at the end near the printed circuit board 1, and the heat-shrinkable layer 28 completely covers the insulating layer 27.

[0025] In actual implementation, an outer sheath layer 26 is set to improve the flexibility of the wire, an insulation layer 27 covers the connection between the outer sheath layer 26 and the conductive layer 25, and a heat-shrinkable layer 28 fully covers the insulation layer 27. The heat-shrinkable layer 28, the insulation layer 27 and the outer sheath layer 26 are the main external structures of the high-speed cable connector, ensuring the balance between the overall structure's flexible bending and mechanical strength, guaranteeing the shielding effect and strength of the wire, and ensuring stable installation without damaging the wire.

[0026] In actual implementation, the insulating layer 27 is preferably acetate tape.

[0027] In actual implementation, the heat-shrinkable layer 28 is preferably encapsulated by a heat-shrinkable sleeve.

The filler layer 22 covers the end of the core wire 21 away from the printed circuit board 1, and the shielding braid layer 23 covers the outside of the filler layer 22.

[0029] In this embodiment, as shown in Figures 2 and 3, the high-speed cable 2 also includes a filler layer 22 and a shielding braid layer 23. The filler layer 22 and the shielding braid layer 23 are the internal structures of the original cable. The filler layer 22 fills the gaps inside the high-speed cable 2, ensuring that the cable structure is compact and stable and improving mechanical strength. The shielding braid layer 23 reduces electromagnetic interference and protects internal signal transmission.

[0030] In actual implementation, during the assembly process of the high-speed cable 2, after the end of the cable is stripped, the length of the filler layer 22 exposed relative to the shielding braid layer 23 is preferably 5~20mm.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the end of the high-temperature layer 24 closest to the printed circuit board 1 is shorter than the core wire 21 and is flush with the end of the printed circuit board 1 closest to the high-speed cable 2. The end of the high-temperature layer 24 furthest from the printed circuit board 1 overlaps with the filler layer 22. The end of the conductive layer 25 furthest from the printed circuit board 1 overlaps with the shielding braided layer 23.

[0032] In this embodiment, as shown in Figures 2 and 3, the length of one end of the high-temperature layer 24 is shorter than that of the core wire 21 and is flush with one end of the printed circuit board 1, which ensures the stability of the connection between the core wire 21 and the printed circuit board 1. One end of the high-temperature layer 24 overlaps with the filler layer 22, and one end of the conductive layer 25 overlaps with the shielding braid layer 23, making the structure of the high-speed cable 2 compact and improving safety performance.

[0033] In actual implementation, the material of the high-temperature layer 24 has a temperature resistance range of 120℃ to 300℃, and is preferably Teflon high-temperature tape.

[0034] In actual implementation, the conductive layer 25 is preferably a conductive tape.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the outer layer of the high-speed cable 2 is also provided with a conductive layer 29. The conductive layer 29 covers the overlap of the heat-shrinkable layer 28 and the conductive layer 25. The conductive layer 29 is located inside the connector 3 and is in contact with the connector 3 for conduction.

[0036] In this embodiment, as shown in Figures 2 and 3, the conductive layer 29 of the high-speed cable 2 is in contact with the connector 3, which can effectively reduce electromagnetic interference and improve the stability of the circuit.

[0037] In actual implementation, the material of the conductive layer 29 is not specifically limited, but copper foil is preferred.

[0038] In actual implementation, connector 3 is installed on the outside of high-speed cable 2 and printed circuit board 1. After connector upper cover 32 and connector lower cover 31 are closed, the resulting housing abuts against conductive layer 29. Conductive layer 29 covers the overlap of heat shrink layer 28 and conductive layer 25, so that conductive layer 25 and connector 3 are connected through conductive layer 29.

[0039] In one embodiment, such as Figure 1 and Figure 2 As shown, connector 3 also includes a fixing member 33, which is used to connect the upper cover 32 and the lower cover 31 of connector.

[0040] In this embodiment, as shown in Figures 1 and 2, the fastener 33 connects the upper cover 32 and the lower cover 31 of the connector to ensure the stability of the connector 3. At the same time, the printed circuit board 1 and the high-speed cable 2 that are fixedly connected are fixedly installed in the connector 3. The overall structure is simple, with fewer parts, and is easy to install and replace.

[0041] In actual implementation, the fastener 33 is not specifically limited and can be set according to the actual situation, preferably a rivet.

[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the conductivity of the conductive layer 25 is at least 90% of the conductivity of the shielding braid layer 23.

[0043] In this embodiment, as shown in Figures 1 and 2, the conductive layer 25 conducts current or electromagnetic signals to ensure stable data transmission and meet the requirements of high-speed transmission for low resistance and high stability. One end of the conductive layer 25 overlaps with the shielding braided layer 23, and its conductivity is at least 90% of the conductivity of the shielding braided layer 23, ensuring the stability of the overall structure of the high-speed cable connector.

[0044] In actual implementation, one end of the conductive layer 25 extends out of the connector 3.

[0045] In one embodiment, such as Figure 1 and Figure 2 As shown, a pull ring 311 is provided at the end of the connector lower cover 31 away from the printed circuit board 1.

[0046] In this embodiment, as shown in Figures 1 and 2, the pull ring 311 ensures quick disassembly of the high-speed cable connector.

[0047] In actual implementation, the shape of the pull ring 311 is not specifically limited.
