Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of light guides, in particular to a bending-resistant light guide. Background Art
[0002] A light guide (also known as a light beam in an optical fiber) refers to the light propagating through an optical fiber or other optical device. Light guides are transmitted within the optical material through refraction, total internal reflection, and other methods. They are widely used in communications, medical treatment, lighting, and other fields. Optical fibers primarily consist of a core and a cladding. The core has a higher refractive index than the cladding, and total internal reflection keeps light within the core. Light guides are widely used in fiber-optic communications because they can efficiently transmit optical signals with low loss and high bandwidth.
[0003] Existing light guides are usually covered with a flexible sheath to achieve a bending resistance effect. However, the flexible sheath can only protect the light guide when subjected to a relatively small bending force, while the flexible sheath will still bend when subjected to a relatively large bending force. Utility Model Content
[0004] The purpose of the present utility model is to provide a bending-resistant light guide. The bending-resistant light guide disclosed in the present utility model is wrapped with an open-loop sheath, and a plurality of metal wires with good bending resistance are interspersed in a circularly equidistant array inside the open-loop sheath. The flexible open-loop sheath and the metal wires with good bending resistance cooperate to provide the light guide with better anti-bending function and enhance durability, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bending-resistant light guide, comprising a reinforcing core, with a plurality of optical fibers and a remote power supply line bonded and connected to the outside of the reinforcing core, the reinforcing core, the optical fibers and the remote power supply line bundle are successively covered with a tape layer and an outer sheath, the outer sheath is detachably covered with an open-loop sheath, both ends of the side opening of the open-loop sheath are fixedly connected with end strips, and the middle of the opposite surfaces of the end strips at the left and right ends are respectively provided with a snap-fit connection snap strip and a snap groove, the open-loop sheath, the end strip and the snap strip are all made of flexible material, and a plurality of metal wires are interspersed in a circular equidistant array inside the open-loop sheath.
[0006] Preferably, the open-loop sleeve, end strips and buckle strips are all made of rubber.
[0007] Preferably, the open-loop sleeve, end strips and snap strips are all made of silicone material.
[0008] Preferably, the metal wire is made of a metal material with good bending resistance.

[0010] Preferably, the gaps in the tape layer are filled with fillers, and the fillers are coated on the gaps outside the reinforcing core, the optical fiber and the remote power supply harness.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The anti-bending light guide disclosed by the utility model is covered with an open-loop sheath, and a plurality of metal wires with good anti-bending effect are interspersed in a circumferentially equidistant array inside the open-loop sheath. The flexible open-loop sheath and the metal wires with good anti-bending effect cooperate to provide the light guide with better anti-bending function and enhance durability, thereby solving the problem that the existing light guide light usually achieves anti-bending effect by being covered with a flexible sheath, which can only protect the light guide light when subjected to a smaller bending force, while the flexible sheath will still be bent when subjected to a larger bending force.

When subjected to a large bending force, the metal wires 11 with good bending resistance are not easily bent and can resist a large bending force. They cooperate with the flexible open-loop sheath 7 to protect the entire light guide beam.
