[0026] In order to understand the technical content of the utility model more, specific embodiments are raised and the following is described with the attached drawings.

[0027] In combination Figures 1 to 3 with the utility model shown, a torsion-resistant industrial optical fiber light transmission beam is proposed, comprising a plurality of optical fiber filaments 20 and a protective layer covering the optical fiber filaments 20.

[0028] In order to reduce the tensile stress suffered by the optical fiber bundle when bending, all the optical fibers of the light transmission beam are divided into a plurality of optical fiber filaments 20, and at the same time, in order to ensure the accuracy of the transmission of optical signals, each optical fiber filament 20 is arranged according to a predetermined position within the cross section of the light transmission beam.

[0029] As Figure 1 shown, the two ends of the light transmission beam are joint areas 101, and the inside of the joint areas 101 is the middle area 102.

[0030] It should be understood that the joint areas 101 at both ends of the light transmission beam are respectively used for receiving and / or transmitting optical signals, and in order to ensure that the signals are not distorted during transmission through the light transmission beam, the position of the optical fiber filament in the joint area 101 at one end corresponds to the position in the joint area 101 at the other end.

[0031] In combination Figure 2 with the utility model shown, the protective layer in the joint area 101 comprises a plug structure 10, a plurality of optical fiber filaments 20 are arranged in the inner layer of the plug structure 10, and a filling structure 11 is arranged in the gap between the optical fiber filaments 20 and the plug structure 10.

[0032] Optionally, the filling structure 11 is an epoxy resin filling structure.

[0033] Specifically, the plug structure 10 can be inserted into a light emitting device to receive the light signal emitted by the light source, so that the other end of the light transmission beam emits a predetermined light signal, or the plug structure 10 can be inserted into a light signal detection device to receive the light signal received from the measured area.

[0034] In combination Figures 3 to 5 with the utility model shown, the protective layer in the middle area 102 comprises a sheath structure layer, a partition plate 50 is arranged in the sheath structure layer at every predetermined distance, and a plurality of partition holes 51 for the optical fiber filaments 20 to pass through are arranged on the partition plate 50, so that the adjacent optical fiber filaments 20 maintain a predetermined distance and relative position.

[0035] Thus, the plurality of optical fiber filaments 20 are limited and separated by the partition plate 50. Meanwhile, the partition plate 50 forms gaps between the plurality of optical fiber filaments 20, so that the plurality of optical fiber filaments 20 have space to deform when the light transmission beam is bent, thereby reducing the stress.

[0036] Preferably, the partition plate 50 is an elastic plate. Thus, the partition plate 50 itself also has a buffering effect.

[0037] Optionally, the partition plate 50 includes a rubber plate, a nylon plate, or a silica gel plate.

[0038] Further, the wall thickness of the partition area between the two adjacent partition holes 51 on the partition plate 50 is greater than 2-3 mm. The gaps between the plurality of optical fiber filaments 20 separated by the partition plate 50 reduce the pressure and tensile stress between the plurality of optical fiber filaments 20 through the deformation of the partition plate 50 itself and the gaps between the plurality of optical fiber filaments 20 when the light transmission beam is bent, so that the plurality of optical fiber filaments 20 transmit light signals more accurately and are less likely to break and distort under bending and twisting.

[0039] In an optional embodiment, the optical fiber filament 20 includes a plurality of optical fiber filaments 22 arranged in a predetermined shape and a cladding layer 21 covering the plurality of optical fiber filaments 22.

[0040] Optionally, the cladding layer includes a polyethylene cladding layer. Thus, each optical fiber filament 20 can be separated from each other to avoid damage to the skin caused by collision.

[0041] Further, the plurality of optical fiber filaments 22 are arranged in a regular hexagon and / or a rhombus, so that the cross section of the optical fiber filament 20 is close to a circular structure. Optionally, the optical fiber filament 22 is a plastic filament or a glass filament.

[0042] Further, the gap between the sheath structure layer and the optical fiber filament 20 is provided with a lubricating paste 40. Thus, the setting of the lubricating paste 40 can avoid friction and extrusion damage between the plurality of optical fiber filaments 20.

[0043] Preferably, the partition plate 50 is provided with a through hole 52, and the lubricating paste 40 in the gap of each optical fiber filament 20 can pass through the through hole 52. That is, when the light transmission beam is bent, the lubricating paste 40 can flow in the internal space according to the deformation of the sheath, thereby having a buffering and damping effect.

[0044] In the above embodiment, the sheath structure layer includes an inner sheath 31 and an outer sheath 32, the inner sheath 31 includes a polyvinyl chloride sheath, and the outer sheath 32 includes a corrugated pipe. The corrugated pipe has good pressure resistance, so that the light transmission beam has good mechanical properties.

[0045] In conjunction with the above embodiments, the fiber optic transmission beam proposed in this utility model divides multiple fiber filaments into multiple fiber bundles, which can reduce the compactness and cross-sectional size of the fiber filaments. This allows for greater deformation space during bending and twisting, avoiding compressive and tensile stresses between the fiber filaments. In addition, the partition plate can maintain the multiple fiber bundles in a predetermined distribution position, resulting in high resolution of optical signal transmission. At the same time, the partition plate also serves as a buffer element between the various fiber bundles, enabling the transmission beam to meet the requirements of torsion and bending environments.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
