Description

Technical Field

[0001] The utility model relates to the technical field of wires and cables, in particular to a medical 50-ohm cable. Background Art

[0002] With the development of society, cables are more and more widely used in the medical industry. The reliability of cable use is crucial to the detection accuracy of medical equipment, especially some high-standard medical equipment such as CT equipment. During use, the role of the cable is not only to conduct electricity, but also to undertake information collection, data transmission and other functions. This requires certain requirements for the stability of cable use. It can not only meet the requirements of the bending and torsion resistance of the cable during use, but also ensure that the various harnesses inside the cable will not interfere with each other during deformation use, ensuring the accuracy of signal transmission. Certain crosstalk interference is often generated at the near and far ends of the cable, which indirectly affects the quality of the cable transmission signal. This requires the cable to consider the prevention of crosstalk at the beginning of the design. Therefore, a medical 50-ohm cable is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a medical 50-ohm cable to solve the problem of stability of use between various wire bundles during bending and twisting of the cable in the prior art.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A medical 50-ohm cable, comprising a core wire and a protective sheath wrapping the core wire, and further comprising:

[0006] A braided protective layer, which is arranged between the core wire and the protective sleeve and wraps the core wire;

[0007] The core wire includes a wire sleeve, and a 50-ohm cable, a 50-ohm switch cable and a twisted pair wire arranged in the wire sleeve, and an outer wall signal wire is arranged between the circumference of the wire sleeve and the inner wall of the braided protective layer;

[0008] The 50-ohm cable is arranged in the cable sleeve independently from the 50-ohm switch cable and the twisted pair, and a filler is arranged between the 50-ohm cable, the 50-ohm switch cable and the twisted pair to separate them.

[0009] To implement the above technical solution, the braided protective layer can be used to protect the core wire, and the 50-ohm cable is set in the wire sheath independently from the 50-ohm switch cable and the twisted pair wire. This can reduce signal interference between the cables during use, and the filler can support the cable to maintain a constant position in the wire sheath. Even if the entire cable is bent or twisted, the position of each cable in the wire sheath can still be guaranteed, making the cable more stable and reliable to use. The outer wall signal line can not only play the role of signal transmission, but also support the separation between the wire sheath and the inner wall of the braided protective layer, thereby ensuring the stability of the wire sheath.

[0010] In one embodiment of the present invention, the 50-ohm switch cable and the twisted pair cables are inside the cable sheath, close to the inner wall of the cable sheath and arranged in sequence along the circumference of the inner wall of the cable sheath.

[0011] By implementing the above technical solution, the 50-ohm switching cable and the twisted pair are arranged in sequence along the circumference of the inner wall of the cable sheath, which can reduce the mutual influence between the 50-ohm switching cable and the twisted pair during use, thereby improving the stability of the cable.

[0012] In an embodiment of the present invention, the twisted pairs include a set of two-wire twisted pairs and a set of three-wire twisted pairs.

[0013] By implementing the above technical solution, the crosstalk can be effectively reduced by setting different twisting pitches of twisted wires.

[0014] In one embodiment of the present invention, an adhesive tape is provided on the inner side of the inner wall of the braided protective layer to wrap the outer wall signal line.

[0015] To implement the above technical solution, the setting of the tape can, on the one hand, wrap the outer wall signal line tightly around the cable sleeve, and on the other hand, improve the stability and reliability of the overall cable, avoiding misalignment and entanglement between the cables during the twisting process of the cable, which affects the stability of signal transmission.

[0016] In an embodiment of the present invention, one side of the 50-ohm cable is in close contact with the inner wall of the cable sleeve.

[0017] Implementing the above technical solution can improve the position stability of the 50-ohm cable when in use.

[0018] In one embodiment of the present invention, the signal wires are equally divided in the circumferential direction and arranged between the core wire and the inner wall of the braided protective layer.

[0019] By implementing the above technical solution and arranging the signal lines in equal parts, the support stability between the signal lines and the inner wall of the braided protective layer can be improved. In addition, when the cable is twisted and bent, the signal lines will not be entangled, thereby ensuring the stability of the signal lines.

[0020] In one embodiment of the utility model, an inner signal line is further provided in the wire sleeve, and the 50-ohm cable, 50-ohm switch cable, twisted pair wires and inner signal line are arranged alternately in the wire sleeve, and a gap is provided between the 50-ohm cable, 50-ohm switch cable, twisted pair wires and inner signal line and the inner wall of the wire sleeve.

[0021] To implement the above technical solution, the 50-ohm cable, 50-ohm switch cable, twisted pair cable and inner signal line are alternately arranged in the cable sheath, which can reduce the interference of signal transmission between the cables and improve the stability of the entire cable.

[0022] In one embodiment of the present invention, the 50-ohm cable is wrapped with two layers of signal shielding on the outside, and the 50-ohm switch cable is wrapped with one layer of signal shielding on the outside.

[0023] To implement the above technical solution, two layers of signal shielding are used to block the influence of signals emitted from the outside of the 50-ohm cable, and one layer of signal shielding is used to block the influence of signals emitted from the outside of the 50-ohm switch cable, thereby improving the use stability of the entire cable.

[0024] In an embodiment of the present invention, the braided protective layer is made of soft copper tape.

[0025] The above technical solution can achieve good deformation characteristics and strong supporting stability.

[0026] As described above, a medical 50-ohm cable of the utility model has the following beneficial effects: the braided protective layer can protect the core wire, and the 50-ohm cable is set in the cable sheath independently from the 50-ohm switch cable and the twisted pair cable, which can reduce the signal interference between the cables during use, and the filler can support the cable to maintain a constant position in the cable sheath, even if the entire cable is bent or twisted, the position of each cable in the cable sheath can still be guaranteed, making the cable more stable and reliable to use, the outer wall signal line can not only play the role of signal transmission, but also support the separation between the cable sheath and the inner wall of the braided protective layer, thereby ensuring the stability of the cable sheath, and arranging the signal lines in equal parts can improve the support stability between the core wire and the inner wall of the braided protective layer, and can also prevent entanglement between the positions of the signal lines during the twisting and bending of the cable, thereby ensuring the stability of the signal lines in use.

[0032] The braided protective layer 2 can protect the core wire. The 50-ohm cable 4 is arranged in the wire sleeve 3 independently from the 50-ohm switch cable 5 and the twisted pair wire 6. This can reduce signal interference between the cables during use, and the filler 8 can support the cable to maintain a constant position in the wire sleeve 3. Even if the entire cable is bent or twisted, the position of each cable in the wire sleeve 3 can still be guaranteed, making the cable more stable and reliable to use. The outer wall signal line 7 can not only perform the signal transmission function, but also support the separation between the wire sleeve 3 and the inner wall of the braided protective layer 2, thereby ensuring the stability of the wire sleeve 3 in use.

[0033] The 50-ohm switch cable 5 and the twisted pair wire 6 are arranged in sequence along the circumference of the inner wall of the wire sleeve 3 in the wire sleeve 3, and the mutual influence between the 50-ohm switch cable 5 and the twisted pair wire 6 during use can be reduced, thereby improving the stability of the cable.

[0034] The twisted pair cables 6 include a group of two-wire twisted pair cables 6 and a group of three-wire twisted pair cables 6. The different twisting pitches of the twisted pair cables 6 can be used to effectively reduce crosstalk. The inner side of the inner wall of the braided protective layer 2 is provided with a tape 9 that wraps the outer wall signal line 7. The setting of the tape 9 can, on the one hand, wrap the outer wall signal line 7 tightly on the wire sleeve 3, and on the other hand, improve the stability and reliability of the overall cable, and avoid misalignment and entanglement between the cables during the twisting process of the cable, which affects the stability of signal transmission.

[0035] One side of the 50-ohm cable 4 is close to the inner wall of the wire sleeve 3, which can improve the position stability of the 50-ohm cable 4 when in use. The signal line is equally divided circumferentially between the core wire and the inner wall of the braided protective layer 2. The signal line is equally divided and arranged, which can improve the support stability of the signal line between the core wire and the inner wall of the braided protective layer 2. It can also prevent the signal lines from being entangled during the twisting and bending of the cable, thereby ensuring the stability of the signal line in use.

The braided protective layer 2 is made of soft copper tape, which can ensure good deformation characteristics while having strong supporting stability.

[0038] The utility model utilizes a braided protective layer to protect the core wire, and arranges the 50-ohm cable in the wire sheath independently from the 50-ohm switch cable and the twisted pair wire, which can reduce signal interference between the cables during use, and the filler can support the cable to maintain a constant position in the wire sheath. Even if the entire cable is bent or twisted, the position of each cable in the wire sheath can still be guaranteed, making the cable more stable and reliable to use. The outer wall signal wire can not only play the role of signal transmission, but also support the separation between the wire sheath and the inner wall of the braided protective layer to ensure the stability of the wire sheath. The signal wires are arranged in equal parts, which can improve the support stability between the signal wire and the core wire and the inner wall of the braided protective layer. In the process of twisting and bending of the cable, the positions of the signal wires will not be entangled, thereby ensuring the stability of the signal wire.
