[0022] The embodiment of the present application provides an integrated armored cable. When a single inner wire tube fails, the corresponding opening can be opened, and only the failed inner wire tube needs to be replaced without replacing the entire integrated armored cable, thereby preventing waste of resources and reducing maintenance costs.

[0023] Combine the following Figure 1-Figure 11 The technical solution provided in this application is explained in more detail. Example

[0024] See also Figure 1-Figure 9As shown, the integrated armored cable provided by the present application includes an inner wire tube 5 and a sleeve 1 with a lumen 3, the inner wire tube 5 is installed in the lumen 3, and an opening portion 2 is provided on the sleeve 1, wherein: both sides of the opening portion 2 are respectively connected to the outer surface of the sleeve 1 and the corresponding lumen 3, and when in a natural state, the parts of the sleeve 1 located on both sides of the opening portion 2 are butted, overlapped or abutted against each other; the opening portion 2 can be in an open state under the action of an external force, and when in the open state, an opening gap is formed in the opening portion 2, and the opening gap communicates with the outer surface of the sleeve and the corresponding lumen 3, and the opening gap allows the inner wire tube 5 to be taken out of the lumen or installed in the lumen 3.

[0025] Among them, the inner wire tube 5 can be an optical fiber, a circuit conductor 51, an air pipe, a wire feeding tube, a cooling tube, a reserved pipeline, etc.

[0026] The diameter of the lumen 3 is determined by the matched inner wire tube 5, and the diameter of the lumen 3 is different according to the inner wire tube 5 of different diameters. The shape of the lumen 3 can be circular, elliptical, rectangular or other irregular shapes. Preferably, the shape of the lumen 3 matches the outer contour of the inner wire tube 5.

[0027] The integrated armored cable provided by the present application has an opening 2 that closes the lumen 3 in a natural state, and the inner wire tube 5 is not easy to escape from the lumen 3, and the opening 2 can be in an open state under the action of an external force, and the inner wire tube 5 can be taken out of the lumen 3 through the opening 2, or the inner wire tube 5 can be installed in the corresponding lumen 3 through the opening 2, so that the connection between the inner wire tube 5 and the casing 1 is realized, and the disassembly and assembly of the inner wire tube 5 and the casing 1 is convenient. When a single inner wire tube 5 fails, the corresponding opening 2 can be opened, and only the failed inner wire tube 5 is replaced, without replacing the entire integrated armored cable, thereby preventing waste of resources and reducing maintenance costs.

[0028] As an optional embodiment, the lumen 3 is arranged along the length direction of the sleeve 1, such as Fig.10 As shown, the lumen 3 runs through both ends of the casing 1, which is convenient for the installation and removal of the inner wire tube 5 and for wiring.

[0029] Alternatively, one end of the lumen 3 passes through one end of the sleeve 1, or both ends of the lumen 3 are closed ends. The lumen 3 of the above structure can meet the requirement of accommodating the inner line tube 5, and no limitation is made here.

[0030] As an optional embodiment, the opening 2 is arranged along the length direction of the sleeve 1, such as Fig.10 As shown, the opening 2 passes through both ends of the sleeve 1, which is convenient for the installation and removal of the inner wire tube 5 and for wiring.

[0031] Alternatively, one end of the opening 2 passes through one end of the sleeve 1, or both ends of the opening 2 are closed ends. The openings 2 of the above structures can all meet the requirement of replacing the inner wire tube 5, and no limitation is made here.

[0032] As an optional embodiment, the number of lumens 3 is one or more than two, see Figure 5 As shown, the number of lumen 3 is one, see Figure 1-Figure 4 , Figure 6-Figure 9 As shown, when the number of lumens 3 is more than two, the lumens 3 are arranged at intervals around the central axis of the sleeve 1 .

[0033] The above-mentioned arrangement of the lumen 3 is convenient for improving the stability of the structure, arranging the lumen 3 in a limited space, improving the space utilization, and preventing the inner wire tubes 5 in the lumen 3 from interfering with each other.

[0034] As an optional embodiment, all the lumens 3 are independent of each other and are arranged in parallel with each other. This structure can ensure that the transmission of each inner line tube 5 is independent of each other without interference.

[0035] As an alternative embodiment, see Figure 1-Figure 9 As shown, the number and position of the lumens 3 correspond to each other in a one-to-one manner with the openings 2. In this embodiment, one lumen 3 corresponds to one opening 2, so that the inner tube 5 in each lumen 3 can be replaced independently, thereby reducing resource waste and maintenance costs.

[0036] See also Figure 1-Figure 9 As shown, according to different product requirements, the number of lumens 3 is 1-6 (corresponding to the number of inner wire tubes 5), the inner wire tubes 5 can be optical fibers, circuit wires 51, air pipes, wire feeding tubes, cooling tubes, reserved pipes, etc., the reserved pipes can be additional wires, additional cooling pipes, etc., and the corresponding number of openings 2 is 1-6.

[0037] As an optional embodiment, when the number of lumens 3 is three or more, the inner line tube 5 at least includes an optical fiber, a circuit conductor 51 and a trachea.

[0038] In this embodiment, see Figure 1 As shown, the opening portion 2 includes a linear incision, which is arranged along the radial direction of the sleeve 1. In a natural state, parts on both sides of the linear incision are butted against each other.

[0039] The opening 2 of the structure is easy to process, and the sleeve 1 parts on both sides of the opening 2 can be in an open state under the action of external force, so that the inner wire tube 5 can be taken out of the tube cavity 3 through the opening 2 or installed in the tube cavity 3.

[0040] The "external force" in "the opening 2 can be in an open state under the action of an external force" can be human force or an external force of a mechanical device, that is, the opening 2 can be in an open state under the action of human force or a mechanical device. The "natural state" refers to the state when the opening 2 is not subjected to an external force, the inner wire tube 5 is not installed in the tube cavity 3, or the inner wire tube 5 is installed in the tube cavity 3. Example

[0041] See also Figure 2 As shown, the difference between this embodiment and embodiment 1 is that: the opening portion 2 of this embodiment includes an overlapping cut 21, and the shape of the overlapping cut 21 on the radial cross section is a straight line or an arc or other irregular shape; on both sides of the overlapping cut 21, one side is formed with a receiving portion 12, and the other side is formed with a overlapping portion 11. In a natural state, the overlapping portion 11 is overlapped on the receiving portion 12 and forms an overlapping portion in the radial direction of the sleeve 1.

[0042] The opening 2 of the structure, such as Figure 2 As shown, the overlapping portion 11 is overlapped on the receiving portion 12 and forms an overlapping portion in the radial direction of the sleeve 1, so that the sleeve 1 has a higher cleanliness and external dust is not easy to enter the tube cavity 3 from the opening 2.

[0043] As an alternative embodiment, see Figure 2 As shown, the opening portion 2 further includes a radial incision 22 , which is arranged along the radial direction of the sleeve 1 , and the radial incision 22 connects the lumen 3 and one side of the overlapping incision 21 , and the other side of the overlapping incision 21 is connected to the outer surface of the sleeve 1 .

[0044] The overlapping cutout 21 can improve the cleanliness of the sleeve 1 from the outside of the radial cutout 22, and the radial cutout 22 facilitates the opening 2 to be in an open state under the action of external force. The opening 2 of this structure can improve the cleanliness of the sleeve 1 and ensure the smooth opening of the opening 2. Example

[0045] See also Figure 3 and Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the parts of the sleeve 1 located on both sides of the opening 2 form a tube flap 13, and in the two tube flaps 13 formed in the same opening 2: the tube flap 13 includes an arcuate surface 131, and in a natural state, the two arcuate surfaces 131 located at different tube flaps 13 abut and squeeze each other to form a sealing surface 14, and the sealing surface 14 closes the tube cavity 3.

[0046] See also Figure 4 As shown, when the tube flap 13 is subjected to an external force, the direction of the external force is the direction of the arrow in the figure, the arc surface 131 on the tube flap 13 is not squeezed, and the opening 2 can be in an open state, and the inner wire tube 5 can be taken in and out of the opening 2. Figure 3 As shown, in the natural state, the sleeve 1 is not subjected to external force, and under the action of the elastic restoring force of the tube flap 13, the two arc surfaces 131 located at different tube flaps 13 abut against and squeeze each other to form a sealing surface 14, and the sealing surface 14 closes the tube cavity 3, as shown in FIG. Figure 3 shown.

[0047] The sleeve 1 of this embodiment is made of elastic material, and has the characteristics of good flexibility, corrosion resistance, and high tensile strength, such as rubber (silicone, silicone rubber, PVC, TPC, TPE, TPU, etc.). The sleeve 1 with this structure can achieve: when the sleeve 1 is not subjected to external force, the two arc surfaces 131 located at different tube petals 13 abut against and squeeze each other under the action of the elastic restoring force to form a sealing surface 14.

[0048] In the opening portion 2 of the present embodiment, two arcuate surfaces 131 located at different tube petals 13 abut against and squeeze each other to form a sealing surface 14 . The sealing surface 14 can seal the tube cavity 3 and also improve the cleanliness of the sleeve 1 . Example

[0049] See also Fig.10 As shown, the opening portion 2 is a curved opening structure arranged around the axis of the sleeve 1. In a natural state, the portion of the sleeve 1 located between two adjacent opening portions 2 is twisted, and the twisted shape can be deformed under the action of external force, thereby allowing the inner wire tube 5 to be taken and placed through the opening portion 2.

[0050] With regard to the opening 2 of this structure, when the inner wire tube 5 is placed in the lumen 3, in a natural state, the portion of the sleeve 1 between two adjacent openings 2 is twisted, and the portion of the sleeve 1 between two adjacent openings 2 can play a certain limiting role, thereby preventing the inner wire tube 5 from slipping out of the lumen 3 from the opening 2.

[0051] Alternatively, as an embodiment not shown, the opening 2 may be disposed along the axis of the sleeve 1 .

[0052] As an alternative embodiment, see Fig.11 As shown, the inner wire tube 5 includes a circuit conductor 51, and the circuit conductor 51 includes a conductor body, a shielding layer 513, a braided layer 514 and a sheath 515 from the inside to the outside, wherein: the shielding layer covers and fixes all the conductor bodies in the same circuit conductor 51, and the shielding layer 513 is made of enhanced shielding material.

[0053] The wire body includes a conductor 511 and an insulating layer 512 coated outside the conductor. The shielding layer can be aluminum foil or copper foil, which plays a role in enhancing the shielding and protecting the wire body from external electromagnetic interference. The braided layer 514 plays a role in increasing the strength. The braided layer material is a metal wire such as TC, steel wire, etc. The circuit wire 51 has sufficient tensile strength and compressive strength. Even if the armored cable is strongly dragged and pulled, it will not cause the power supply wire and other cables to be damaged due to dragging. The sheath material can be PVC, TPE or TPU, etc. The circuit wire 51 is an integrated anti-shielding drag chain wire. Example

[0054] This embodiment provides a laser device, including the above-mentioned integrated armored cable.

[0055] Since the laser device is provided with the above-mentioned integrated armored cable, the maintenance of the inner wire tube 5 is convenient.
