Abstract
Description
Technical Field
[0001] The utility model relates to the field of optical cable fittings, in particular to an optical cable wall-penetrating guide hole fitting. Background Technique
[0002] When an optical cable passes through a wall hole, it is not only unbeautiful, but also the wall hole is easy to rub against the optical cable. Frequent movement of the optical cable is easy to cause wear. Some optical cable wall-penetrating guide hole fittings have complex structures and are not convenient for installation.
[0003] Therefore, it is necessary to provide an optical cable wall-penetrating guide hole fitting to solve the above technical problems. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides an optical cable wall-penetrating guide hole fitting.
[0005] An optical cable wall-penetrating guide hole fitting provided by the utility model includes a sleeve member for being embedded and installed in a wall body. An avoidance notch for the sleeve member to be extruded and deformed is arranged on the side wall of the sleeve member. A plurality of anti-detachment parts for preventing the sleeve member from detaching from the wall body are arranged on the side wall of the sleeve member. The fitting further includes a rear cover assembly. The rear cover assembly includes a cover body and a plug-in part arranged on one side of the cover body for being plugged into the sleeve member. A cable installation notch for installing an optical cable is arranged on the side wall of the plug-in part.
[0006] Preferably, a groove for avoiding cables is arranged on the inner side of the cover body.
[0007] Preferably, the groove and the cable installation notch are in the same plane.
[0008] Preferably, a chamfer is arranged at the end of the plug-in part.
[0009] Preferably, a rounded corner is arranged at the outer edge of the cover body.
[0010] Compared with the related technology, the utility model provided has the following beneficial effects:
[0011] The guide hole fitting for passing optical cables through a wall can effectively protect the outer sheath of the optical cable during the process of the optical cable passing through the wall. In particular, it can play a good protective role for small-diameter bare optical fibers with diameters of 900um, 600um, and 250um. At the same time, it is more convenient for threading, and even can realize a 90° turn of the optical cable within a certain range, and the installation is relatively convenient.

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Please refer to Figures 1 to 3 , an optical cable wall - piercing guide hole fitting, comprising a sleeve member 1 and a rear cover assembly 4. The sleeve member 1 is used for embedded installation in the wall body, and its side wall is provided with an avoidance notch 2 so that it can be appropriately squeezed and deformed during installation to form a tight fit with the wall hole. At the same time, several anti - detachment portions 3 are provided on the side wall of the sleeve member 1 to effectively prevent the sleeve member 1 from falling out of the wall hole during installation or use.
[0018] The rear cover assembly 4 includes a cover body 5 and an insertion portion 6. The insertion portion 6 is provided on one side of the cover body 5 and is used for insertion into the sleeve member 1. The side wall of the insertion portion 6 is provided with an optical cable installation notch 7 for installing and fixing the optical cable. A groove 8 is also provided inside the cover body 5 for avoiding cables to ensure that the cover body 5 can be in close contact with the end of the sleeve member 1.
[0019] When performing the operation of the optical cable passing through the wall, first, a hole needs to be drilled in the wall. Then, the sleeve member 1 is installed into this hole. Since the diameter of the hole is slightly smaller than the outer diameter of the sleeve member 1, the sleeve member 1 will be squeezed and deformed to a certain extent during installation, so as to form a tight fit with the wall hole. The design of the anti - detachment portion 3 further enhances the connection tightness between the sleeve member 1 and the wall hole.
[0020] Next, one end of the optical cable is placed into the optical cable installation notch 7 on the side wall of the insertion portion 6 of the rear cover assembly 4 and passes out from the end of the insertion portion 6. In this way, the optical cable is firmly fixed on the insertion portion 6.
[0021] Then, the insertion portion 6 of the rear cover assembly 4 is inserted into the sleeve member 1 that has been installed in the wall hole. Since the end of the insertion portion 6 is provided with a chamfer 9, this greatly facilitates the smooth insertion of the insertion portion 6 into the inner side of the sleeve member 1. When the insertion portion 6 is completely inserted into the sleeve member 1, the cover body 5 of the rear cover assembly 4 will be in close contact with the end of the sleeve member 1. At this time, the optical cable is exactly located in the groove 8 inside the cover body 5. The design of this groove 8 not only provides sufficient space for the optical cable but also ensures the stability and safety of the optical cable during installation.
[0022] It should be noted that the inner diameter of the insertion part 6 is slightly smaller than the inner diameter of the deformed sleeve part 1, which enables the insertion part 6 to remain stable inside the sleeve part 1 and is not easily loosened or detached. After the installation is completed, the user can also rotate the rear cover assembly 4 as needed to adjust the orientation of the groove 8, thereby conveniently adjusting the orientation of the optical cable to meet different installation and usage requirements.
[0023] Generally speaking, this optical cable wall-penetrating guide hole fitting has the advantages of reasonable design, convenient installation, stable use, etc., and is an ideal choice for the optical cable to pass through the wall.
[0024] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
