DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] As introduced in the background, there are deficiencies in the prior art, in order to solve the above technical problems, the present application provides a protective sleeve of a medical AOC cable.

[0020] Please refer to Figures 1-4 ​The utility model relates to a protection sleeve of medical AOC cable, the protection sleeve 1 sets up the end of AOC cable 2, is connected with optical module 3, and the protection sleeve 1 includes stop 11, integral crimp ring 12 and outer sheath 13, the front end of stop 11 is equipped with the card board 111, is clamped in the shell of optical module 3, and the rear end is inserted to the inside of AOC cable 2, integral crimp ring 12 is set up the periphery of AOC cable 2 and stop 11, and outer sheath 1 is set up the periphery of integral crimp ring. AOC cable 2 includes sheath layer 21, aramid layer 22, spiral armoured tube layer 23 and optical fiber 24 in turn from outside to inside, and sheath layer 21 is TPU material;Spiral armoured tube layer 23 is made of steel band, steel wire, aluminium band and other metal materials;The shell of optical module 3 is equipped with the clamping groove 31 adapted to card board 111.

[0021] The utility model relates to a protection sleeve of medical AOC cable, the protection sleeve sets up the end of AOC cable 2, is connected with optical module 3, wherein, the protection sleeve 1 includes stop 11, integral crimp ring 12 and outer sheath 13, the front end of stop 11 is provided with card board 111, and is clamped in the clamping groove 31 of the shell of optical module 3, avoids the stress injury of AOC cable in the process of dragging and bending;Integral crimp ring 12 is set up inside outer sheath 13, and stop 11 and AOC cable 2 are sleeved in its inside, guarantee the stability of AOC cable 2 installation.

[0022] Refer to Figure 4 The AOC cable 2 used in the application includes a sheath layer 21, an aramid layer 22, a spiral armoured tube layer 23, and an optical fiber 24. Compared with traditional cables, the AOC cable 2 has an additional sheath layer 21 and an additional aramid layer 22, which makes the AOC cable 2 have high strength, high toughness, and good corrosion resistance, effectively protects the internal optical fiber 24, and also has the characteristic that traditional optical fibers are easy to bend.

[0023] Specifically, the AOC cable of the application has the following characteristics:

[0024] 1. High mechanical strength:

[0025] The AOC cable can significantly improve its mechanical strength, so that it can withstand greater tension, pressure, and lateral pressure. The spiral armoured tube layer can withstand pressure, and the aramid layer can withstand tension, so that stress is not applied to the optical fiber.

[0026] 2. Strong corrosion resistance:

[0027] The sheath layer of the AOC cable can also provide additional waterproof and corrosion protection for the cable, especially in humid and highly corrosive environments.

[0028] 3. Strong compression resistance:

[0029] AOC cable can enhance the pressure resistance, so it can be used in places where heavy pressure needs to be borne. This pressure resistance helps to reduce the risk of cable damage due to external pressure.

[0030] 4. Good wear resistance:

[0031] During long-term use, the sheath layer of the AOC cable can effectively reduce the friction and wear of the cable with the surrounding environment. This helps to prolong the service life of the AOC module and reduce the failure rate caused by wear and tear.

[0032] 5. Small volume:

[0033] Due to the small size and light weight of optical fibers compared to cables, using optical fibers to transmit signals in some endoscopic environments can improve the patient experience.

[0034] 6. Good electromagnetic shielding performance

[0035] The spiral armor layer forms a Faraday cage effect, reducing electromagnetic interference (EMI) and ensuring data transmission stability.

[0036] In a preferred embodiment, referring to Figure 1 and Figure 3 The rear end of the stopper 11 of the protective sleeve 1 of the medical AOC cable is provided with a plurality of outwardly protruding convex rings 112, which ensure the connection of the rear end of the stopper with the AOC cable. The front end of the integrated crimp ring 12 is in interference fit with the AOC cable, further ensuring the stability of the installation of the stopper 11 and the integrated crimp ring 12; the inner wall of the rear end of the integrated crimp ring 12 is provided with an internal thread 121, and the inner wall of the outer sheath 13 is provided with a snap ring groove 131 adapted to the integrated crimp ring. The snap ring groove 131 clamps the integrated crimp ring 12 to prevent the protective sleeve 1 from being separated from the AOC cable 2.

[0037] The protective sleeve of the present application has characteristics such as durability, reliability and comfort, and the product is suitable for deployment in complex environments, such as high temperature, high pressure and corrosive environments, especially for but not limited to medical environments, for data transmission between devices, in emergency, carrying out scenes may involve direct dragging device fast movement, cable needs to be superimposed on the device. The armored AOC cable has higher durability due to its special structure and additional protective layer. This makes the armored AOC cable perform well in medical environments and a variety of application scenarios, and provides users with more reliable and stable communication transmission services.

[0038] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
