Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication line installation technology, and in particular to a connector for communication lines. Background Technology
[0002] With the increasing demand for communication bandwidth, optical fibers are widely used in wired communication networks. A connector is a device that provides a detachable (movable) connection between an optical fiber and a receiver. It precisely aligns the two end faces of the optical fiber to maximize the coupling of light energy from the transmitting fiber to the receiving fiber, minimizing the impact on the system caused by its intervention in the optical link. Currently, connectors on the market involve relatively complex connection steps, thus reducing production efficiency. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a connector for communication lines.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a connector for a communication line, comprising a ceramic ferrule having a first end and a second end, a tail shank and a pagoda connector connecting the ceramic ferrule, a snap-fit sleeve protecting the ceramic ferrule, a connector housing connecting the snap-fit sleeve, and a tail tube for mounting the pagoda connector. The first end of the ceramic ferrule is inserted into the snap-fit sleeve, and the outer wall of the snap-fit sleeve is snap-fitted into the connector housing. The second end of the ceramic ferrule is provided with a jack for inserting an optical fiber. The tail shank is mounted on the second end of the ceramic ferrule, and a thermoplastic tube is installed on the tail shank. A spring is fitted on the thermoplastic tube, and the spring provides pressure during connection. The second end of the ceramic ferrule is inserted into the pagoda connector, and the pagoda connector is inserted into the tail tube.
[0005] As a further description of the above technical solution:
[0006] The pagoda connector is provided with a first retaining ring and a second retaining ring. The pagoda connector is engaged in the tail tube by the first retaining ring, and the second retaining ring is used to engage and connect the pagoda connector and the retaining sleeve.
[0007] This utility model has the following beneficial effects:
[0008] By using a locking mechanism that integrates ceramic ferrules, tailstock, pagoda connectors, snap-fit sleeves, connector outer casing, and tail tube, the installation time for communication optical fibers is saved, thereby improving work efficiency. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Reference Figures 1 to 2 As shown, the present invention adopts the following technical solution: a connector for a communication line, comprising a ceramic ferrule 1 having a first end 11 and a second end, a tail shank 2 and a pagoda connector 3 connecting the ceramic ferrule 1, a snap-fit sleeve 4 protecting the ceramic ferrule 1, a connector housing 5 connecting the snap-fit sleeve 4, and a tail tube 6 for installing the pagoda connector 3. The first end 11 of the ceramic ferrule 1 is inserted into the snap-fit sleeve 4, and the outer wall of the snap-fit sleeve 4 is snapped into the connector housing 5. The second end of the ceramic ferrule 1 is provided with a jack 7 for inserting optical fibers. The tail shank 2 is installed on the second end of the ceramic ferrule 1, and a thermoplastic tube 8 is installed on the tail shank 2. A spring 9 is sleeved on the thermoplastic tube 8, and the spring 9 provides pressure during connection. The second end of the ceramic ferrule 1 is inserted into the pagoda connector 3, and the pagoda connector 3 is inserted into the tail tube 6.
[0015] The pagoda connector 3 is provided with a first retaining ring 31 and a second retaining ring 32. The pagoda connector 3 is engaged in the tail tube 6 by the first retaining ring 31, and the second retaining ring 32 is used to engage and connect the pagoda connector 3 and the retaining sleeve 4.
[0016] Usage steps:
[0017] Use fiber optic strippers to remove the outer sheath of the optical fiber, exposing a certain length of fiber. Inject glue into the socket 7 of the ceramic ferrule 1 to fix the fiber, ensuring a tight fit between the ceramic ferrule 1 and the fiber. Install the tail shank 2 on the second end of the ceramic ferrule 1, and then put the thermoplastic tube 8 on the tail shank 2 for heating and curing. After heating and curing, the thermoplastic tube 8 will shrink and firmly fix the fiber with the glue, ensuring that the end face of the fiber is flush with the end face of the ceramic ferrule 1. Next, put the spring 9 on the thermoplastic tube 8, ensuring that the spring 9 can provide appropriate pressure. Then, insert the tail shank 2 with the thermoplastic tube 8 and spring 9 into the pagoda connector 3 and the snap-fit sleeve 4. The pagoda connector 3 is inserted into the tail tube 6, and the snap-fit sleeve 4 is inserted into the connector housing 5.
[0018] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
