Technical Field
[0001] This utility model relates to the field of optical fiber cable connection technology, and in particular to a quick optical fiber cable adapter structure. Background Technology
[0002] Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. In the use of fiber optic cables, adapter structures are required to form a continuous optical path between two optical fibers or cables.
[0003] Currently, most fiber optic adapter structures are pre-assembled in the factory according to customer needs, and then delivered to the customer for on-site installation and use. However, when the fiber optic adapter structure is accidentally damaged or the actual required length of the fiber optic cable is uncertain, it is impossible to terminate the fiber optic adapter structure in advance in the factory. To ensure the construction progress of the fiber optic connection, rapid assembly is often required outside the factory, such as at the construction site, to improve construction efficiency. Furthermore, because the fiber optic adapter structure requires extremely high connection precision, assembly personnel must ensure that the fiber optic adapter structure is properly assembled and that the internal fiber optic cables are precisely connected to achieve fiber optic path connectivity and guarantee fiber optic connection accuracy.
[0004] Therefore, how to improve the assembly efficiency between optical fiber cables and optical fiber adapter structures, while ensuring accurate connection of optical fiber cables and guaranteeing the precision of optical fiber connections, has become an urgent technical problem to be solved. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a quick fiber optic cable adapter structure with high connection efficiency and accurate docking.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a quick fiber optic cable adapter structure is provided, including a left shell, a left tail sleeve, a connecting sleeve, a right shell, and a right tail sleeve.
[0007] The left housing is hollow and has a left channel, which includes a first left cavity for the passage of optical fiber cables and a second left cavity for the passage of optical fibers in the optical fiber cables.
[0008] A connecting sleeve is fitted and rotatably connected to the right end of the left housing;
[0009] The left tail end sidewall of the left housing is divided into multiple clamping blocks by multiple longitudinal through grooves; the diameter of the left tail end sidewall gradually decreases to the left, and the left tail sleeve is threaded onto the clamping block.
[0010] The right housing is hollow and has a right channel, which includes a first right cavity for the passage of optical fiber cables and a second right cavity for the passage of optical fibers in the optical fiber cables.
[0011] The right end of the right housing is provided with an external thread that is threaded to the connecting sleeve;
[0012] The right tail end sidewall of the right housing is divided into multiple clamping blocks by multiple longitudinal through grooves; the diameter of the right tail end sidewall gradually decreases to the right, and the right tail sleeve is threaded onto the clamping block.
[0013] The beneficial effects of this invention are as follows: The left and right housings of this invention are respectively used for two different optical fiber cables. When splicing two optical fiber cables, the optical fiber cable passes through the first right cavity of the right housing, and the optical fiber of the optical fiber cable passes through the second right cavity. The left housing performs the same operation for the other optical fiber cable, and then the connecting sleeve is rotated, and the internal thread of the connecting sleeve is threadedly connected to the external thread of the right housing, thereby accurately splicing the optical fibers of the two different optical fiber cables in the second left cavity or the second right cavity. After splicing, the left and right tail sleeves are screwed into the corresponding clamping blocks, so that the clamping blocks clamp the corresponding optical fiber cables, improving the connection stability between the two optical fiber cables.

[0023] The left tail end sidewall of the left housing 1 is divided into multiple clamping blocks 6 by multiple longitudinal through grooves; the diameter of the left tail end sidewall gradually decreases to the left, and the left tail sleeve 2 is threaded onto the clamping block 6.
[0024] The right housing 4 is hollow and has a right channel, which includes a first right cavity for the optical fiber cable 7 to pass through and a second right cavity for the optical fiber 71 of the optical fiber cable to pass through.
[0025] The right end of the right housing 4 is provided with an external thread that is threaded to the connecting sleeve 3;
[0026] The right tail end sidewall of the right housing 4 is divided into multiple clamping blocks 6 by multiple longitudinal through grooves; the diameter of the right tail end sidewall gradually decreases to the right, and the right tail sleeve 5 is threaded onto the clamping block 6.
[0027] The beneficial effects of this utility model are as follows: The left housing 1 and right housing 4 of this utility model are used for two different optical fiber cables respectively. When splicing the two optical fiber cables, the optical fiber cable passes through the first right cavity of the right housing 4, and the optical fiber of the optical fiber cable passes through the second right cavity. The left housing 1 performs the same operation for the other optical fiber cable, and then the connecting sleeve 3 is rotated. The internal thread of the connecting sleeve 3 and the external thread of the right housing 4 are threadedly connected, thereby accurately splicing the optical fibers of the two different optical fiber cables in the second left cavity 13 or the second right cavity. After splicing, the left tail sleeve 2 and the right tail sleeve 5 are screwed into the corresponding clamping blocks 6 respectively, so that the clamping blocks 6 clamp the corresponding optical fiber cables, improving the connection stability between the two optical fiber cables.
[0028] Furthermore, in the aforementioned quick fiber optic cable adapter structure, an annular protrusion is provided on the inner wall of the end of the connecting sleeve 3 that is fitted with the left housing 1, and an annular groove that slides with the annular protrusion is provided on the outer wall of the left housing 1.
[0029] As can be seen from the above description, with the left housing 1 and the right housing 4 stationary, the left housing 1 and the right housing 4 can be connected by rotating the connecting sleeve 3.
[0030] Furthermore, in the aforementioned quick fiber optic cable adapter structure, a left protective sleeve is fitted onto the left housing 1, and the material of the left protective sleeve is elastic insulating rubber.
[0031] As described above, the left protective sleeve can be fitted onto the connection between the left housing 1 and the connecting sleeve 3 for sealing, dustproofing, waterproofing, etc.
[0032] Furthermore, in the aforementioned quick fiber optic cable adapter structure, a right protective sleeve is fitted on the right housing 4, and the material of the right protective sleeve is elastic insulating rubber.
[0033] As described above, the right protective sleeve can be fitted onto the connection between the right housing 4 and the connecting sleeve 3 for sealing, dustproofing, waterproofing, etc.
[0034] Furthermore, in the aforementioned quick fiber optic cable adapter structure, the left channel also includes a left guide channel 12 with a gradually decreasing diameter located between the first left cavity 11 and the second left cavity 13.
[0035] As described above, the left guide channel 12 facilitates the smoother entry of optical fibers into the second left cavity 13.
[0036] Furthermore, in the aforementioned quick fiber optic cable adapter structure, the left channel also includes a right guide channel with a gradually decreasing diameter located between the first right cavity and the second right cavity.
[0037] As described above, setting up a right guide channel facilitates smoother entry of optical fibers into the second right cavity.
[0038] Furthermore, in the aforementioned quick fiber optic cable adapter structure, the left tail end sidewall of the left housing 1 is divided into three clamping blocks 6 by two longitudinal through slots.
[0039] As can be seen from the above description, the diameter of the side wall formed by the clamping block 6 gradually decreases. Therefore, when the left tail sleeve 2 is screwed onto the clamping block 6, the clamping block 6 gradually clamps the optical fiber cable.
[0040] Furthermore, in the aforementioned quick fiber optic cable adapter structure, the right tail end sidewall of the right housing 4 is divided into three clamping blocks 6 by two longitudinal through slots.
[0041] As can be seen from the above description, the diameter of the side wall formed by the clamping block 6 gradually decreases. Therefore, when the right tail sleeve 5 is screwed onto the clamping block 6, the clamping block 6 gradually clamps the optical fiber cable.
