[0033] When troubleshooting cables, it is usually necessary to quickly identify the two ends of the same cable. Currently, when searching for cables, a light-guiding optical fiber is usually added to the cable, and a light source emitting device is used to illuminate the optical fiber end of one end of the cable, and the other end of the cable is determined by the light spot generated by the optical fiber end of the other end of the cable. However, in the existing cable structure, the position of the light-guiding optical fiber is not fixed, and the light source emitting device is difficult to align, resulting in reduced cable searching efficiency.

[0034] To solve the above problems, the present invention proposes a wire protection sleeve, which aims to solve the problem that the position of the existing light-guiding optical fiber is difficult to fix on the crystal head, which makes it difficult for the light source emitting device to accurately align the position of the light-guiding optical fiber, resulting in reduced line-finding efficiency.

[0035] like Figures 1 to 3 In one embodiment, the cable protection sleeve 10 includes a cable protection portion 11 and a mounting portion 12. The cable protection portion 11 is provided with a first threading hole 111. One end of the mounting portion 12 is connected to the cable protection portion 11, and the other end is used to be connected to the crystal head body 20. The mounting portion 12 is provided with a second threading hole 121 connected to the first threading hole 111. The first threading hole 111 and the second threading hole 121 are used for one end of the cable to be passed through in sequence. The mounting portion 12 is provided with a through insertion hole 122. An opening of the insertion hole 122 is connected to an opening of the second threading hole 121 away from the cable protection portion 11, and the axial direction of the insertion hole 122 is consistent with the axial direction of the first threading hole 111 or the second threading hole 121.

[0036] The end of the wire insertion hole 122 away from the wire protection part 11 is used for the light-guiding optical fiber in the cable to pass through, and the end of the wire insertion hole 122 close to the wire protection part 11 is used for an external light source emitting device to align with and illuminate the light-guiding optical fiber.

[0037] In this embodiment, the wire protection part 11 is made of a highly elastic plastic material and is cylindrical in shape. The wire protection part 11 is provided with a through first threading hole 111 along its own axial direction for the cable to be threaded. The connection between the mounting part 12 and the wire protection part 11 is made by an integrated design to ensure the installation stability between the two. The mounting part 12 is provided with a through second threading hole 121 corresponding to the first threading hole 111 along its own axial direction. The second threading hole 121 is connected to the first threading hole 111, and the aperture size of the two is the same and the axial direction is consistent to ensure that the cable can smoothly pass through the wire protection part 11 and the mounting part 12.

[0038] The mounting portion 12 is also provided with a through-hole 122, which is connected to an opening of the second threading hole 121 away from the wire protection portion 11. After the cable passes through the wire protection portion 11 and the mounting portion 12 in sequence, the light-guiding optical fiber inside the cable is inserted into the wire insertion hole 122 from one end of the wire insertion hole 122 away from the wire protection portion 11 and passes out from the other end, and then the passed-out part is cut to ensure that the light-guiding optical fiber fills the entire wire insertion hole 122 and is aligned with the outlet of the wire insertion hole 122 so as to be connected to the external light source emitting device, thereby improving the convenience of laser conduction. Then, the external light source emitting device is aligned with the end of the wire insertion hole 122 close to the wire protection portion 11 so that the light source can illuminate the light-guiding optical fiber to achieve light transmission.

[0039] The wire protection sleeve 10 proposed in the present invention includes a wire protection part 11 and a mounting part 12. The wire protection part 11 is provided with a first wire threading hole 111. One end of the mounting part 12 is connected to the wire protection part 11, and the other end is used to be inserted into the crystal head. At the same time, the mounting part 12 is provided with a second wire threading hole 121 connected to the first wire threading hole 111. The first wire threading hole 111 and the second wire threading hole 121 are used for one end of the cable to be inserted in sequence. The mounting part 12 is provided with a through wire insertion hole 122. When the wire protection sleeve 10 is put on one end of the cable, the light-guiding optical fiber of the cable is inserted into the wire insertion hole 122 at the end of the mounting part 12 away from the wire protection part 11, so as to fix the light-guiding optical fiber. When the cable needs to be traced, it is only necessary to align the light source emitting device at the end of the mounting part 12 close to the wire protection part 11 with the wire insertion hole 122, so as to accurately align the light-guiding optical fiber, thereby improving the traceability efficiency.

[0040] like Figures 1 to 3 In one embodiment, a guide portion 13 is provided at an opening edge of one end of the wire insertion hole 122 close to the wire protection portion 11, and a through hole 131 is opened in the guide portion 13, and the through hole 131 is connected to the wire insertion hole 122;

[0041] The wire insertion hole 122 and the through hole 131 are used for the light-guiding optical fiber to pass through in sequence, and the guide portion 13 is used for the transmission channel of the external light source emitting device to be sleeved so that the light source center of the external light source emitting device and the center of the through hole 131 are located on the same axis.

[0042] In the present embodiment, the guide portion 13 is a raised structure and is provided with a through hole 131, which is connected to the wire insertion hole 122. Specifically, in the present embodiment, the transmitting end of the external light source emitting device is a needle-shaped structure, and the needle-shaped structure is provided with a transmission channel along its length direction. The inner diameter of the transmission channel is adapted to the outer diameter of the guide portion 13. When searching for a line, the transmission channel of the transmitting end is directly mounted on the guide portion 13. At this time, the laser emitted by the external light source emitting device can be directly transmitted to the light-guiding optical fiber in the through hole 131 and the wire insertion hole 122 through the transmission channel, so that the light-guiding optical fiber can complete the light-guiding work. The provision of the guide portion 13 further improves the ease of operation and the alignment accuracy of the external light source emitting device to align the light-guiding optical fiber, and ensures that the laser can be stably transmitted to the light-guiding optical fiber.

[0043] Since the installation environment of the cable is relatively complex, in actual working conditions, the transmission channel of the transmitting end is easily blocked by the external environment, making it difficult to align the guide part 13. Therefore, in other embodiments, the guide part 13 can be set to multiple, and multiple light-guiding optical fibers are correspondingly arranged in the cable, one light-guiding optical fiber corresponds to one guide part 13, and the setting of multiple guide parts 13 further reduces the difficulty of aligning the external light source emitting device and the light-guiding optical fiber, thereby improving the practicality of the cable protection sleeve 10.

[0044] like Figures 1 to 3 In one embodiment, one end of the guide portion 13 away from the mounting portion 12 is an arc surface.

[0045] In this embodiment, the design of the arc surface makes the cross-section of the guide portion 13 gradually decrease in the direction away from the mounting portion 12, so that the transmission channel of the emitting end of the above-mentioned external light source emitting device is easy to be inserted into the guide portion 13. At the same time, the design of the arc surface reduces the friction between the guide portion 13 and the inner diameter of the transmission channel, thereby further improving the convenience of connection between the two and improving the practicality of the wire sheath 10.

[0046] like Figures 1 to 3 In one embodiment, the radial diameter of the guide portion 13 is D, where 0.4 cm <D<0.6cm。

[0047] In this embodiment, on the one hand, since the guiding portion 13 serves to guide the external light source emitting device to align with the light guiding optical fiber within the guiding portion 13, the volume of the guiding portion 13 itself should not be too small, and thus the radial diameter of the guiding portion 13 should not be too small. On the other hand, due to the limitation of the cross-sectional area of the mounting portion 12 itself and the inner diameter of the transmission channel at the emitting end of the external light source emitting device, if the volume of the guiding portion 13 is too large, it will be difficult to insert the transmission channel into the guiding portion 13, and at the same time, it will increase the production cost. Therefore, the radial diameter D of the guiding portion 13 is set in the range of 0.4 cm < D < 0.6 cm, such as 0.45 cm, 0.5 cm, 0.55 cm, etc.

[0048] For example Figures 1 to 3 , in one embodiment, an avoidance groove 14 is formed between the adjacent opening edges of the second wire passing hole 121 and the wire inserting hole 122, so that the wire inserting hole 122 and the second wire passing hole 121 are communicated with each other.

[0049] In this embodiment, when the cable passes through the second wire passing hole 121, the light guiding optical fiber in the cable needs to extend out of the second wire passing hole 121 alone and be inserted into the wire inserting hole 122. After the light guiding optical fiber extends out of the second wire passing hole 121, it can enter the wire passing hole through the avoidance groove 14. The setting of the avoidance groove 14 can further limit the insertion path of the light guiding optical fiber, thereby improving its own insertion stability.

[0050] For example Figures 1 to 3 , in one embodiment, the bottom surface of the avoidance groove 14 is an arc surface.

[0051] In this embodiment, the bottom surface of the avoidance groove 14 is arranged in an arc shape, so that the light guiding optical fiber can smoothly transition from the second wire passing hole 121 to the inside of the wire passing hole, avoiding damage to the light guiding optical fiber caused by the angle of the avoidance groove 14 itself during the process of inserting the light guiding optical fiber from the second wire passing hole 121 to the inside of the wire passing hole, and thus improving the service life of the light guiding optical fiber.

[0052] For example Figures 1 to 3 , in one embodiment, the length of the wire protecting portion 11 is L, where 1.5 cm < L < 2.5 cm.

[0053] In this embodiment, if the length of the wire protecting portion 11 is too long, it will limit the movement of the cable, and thus increase the difficulty of aligning the external light source emitting device with the guiding portion 13. If the length of the wire protecting portion 11 is too short, the protection effect of the wire protecting portion 11 on the cable will be greatly reduced. Therefore, the length L of the wire protecting portion 11 is set in the range of 1.5 cm < D < 2.5 cm, such as 1.7 cm, 2.0 cm, 2.3 cm, etc.

[0054] For example Figures 1 to 5The present invention also proposes a crystal head, which includes a crystal head body 20 and a wire protection sleeve 10, wherein the mounting portion 12 is connected to the crystal head body 20, and the specific structure of the wire protection sleeve 10 refers to the above embodiment. Since the wire protection sleeve 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0055] like Figures 1 to 5 In a specific embodiment, the mounting portion 12 includes a mounting body 123 and an insertion end 124, the insertion end 124 is connected to one end of the mounting body 123 away from the wire protection portion 11, the insertion end 124 is provided with an insertion slot 1241, the crystal head body 20 is provided with a mounting cavity 21, the bottom wall of the mounting cavity 21 is provided with a mounting opening 211, the edge of the mounting opening 211 is movably connected with a clamping portion 212, the insertion end 124 is inserted into the mounting cavity 21, and the clamping portion 212 is clamped in the insertion slot 1241.

[0056] In this embodiment, there are two plug-in ends 124, which are spaced apart in a direction perpendicular to the direction of their own plug-in, and each plug-in end 124 begins to have a plug-in slot 1241. The clamping portion 212 is a clamping block, and the outer contour of the clamping block is adapted to the shape of the plug-in slot 1241. When the mounting portion 12 is plugged into the crystal head body 20, the plug-in end 124 of the mounting portion 12 is first preliminarily plugged into the mounting cavity 21. After the plug-in end 124 is plugged into the designated position, the clamping portion 212 movably connected to the edge of the mounting port 211 is rotated into the mounting slot, so that the mounting portion 12 is stably mounted to the crystal head body 20, thereby improving the mounting stability between the two.

[0057] The present invention also proposes a cable (not shown), which includes two crystal plugs and a cable body, and the two crystal plugs are respectively inserted at the two ends of the cable body. When an external light source emitting device irradiates one end of a light-guiding optical fiber in a crystal plug, a light spot is generated at the other end of the light-guiding optical fiber in the other crystal plug, thereby completing the line-finding work. The specific structure of the crystal plug refers to the above embodiment. Since the crystal plug adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0058] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
