Optical fiber cable bundling connector

Technical Field

The invention relates to the technical field of optical fiber connectors, in particular to an optical fiber cable bundling connector.

Background

A fiber connector, commonly known as a union, is a reusable passive device for connecting two optical fibers or optical cables to form a continuous optical path, and is a device for performing detachable (movable) connection between the optical fibers, which precisely joints two end faces of the optical fibers so that optical energy output by a transmitting optical fiber can be coupled into a receiving optical fiber to the maximum extent and the influence on a system due to the intervention of the optical fiber into an optical link is minimized, which is a basic requirement of the fiber connector, and to a certain extent, the fiber connector affects the reliability and various performances of an optical transmission system. In installing any optical fiber system, it must be considered to connect optical fibers or optical cables to each other in a low-loss manner to achieve the splicing of optical links. The connection of the optical fiber link can be divided into two types, namely permanent connection and active connection, wherein the permanent connection is mostly realized by adopting a welding method, a bonding method or a fixed connector, the active connection is generally realized by adopting an active connector, and the edge connection of many small and medium-sized local area networks and networks generally belongs to the active connection.

The working principle of the invention is as follows: firstly, a section of end protective sleeve 2 on two optical fibers 1 is stripped, the bare optical fibers 1 are respectively connected with a plug 5 in an insertion shell 3 and a connecting ring 6 in a connecting shell 4, then the insertion shell 3 is inserted in the connecting shell 4, a fixed block 703 in a slot 701 is downwards extruded in the process that the connecting shell 4 moves leftwards, the fixed block 703 can rotate around a fixed rod 702, the fixed block 703 is conveniently turned downwards when being extruded, the fixed block 703 extrudes a spring I704, after the fixed block 703 reaches a position, the fixed block 703 is embedded with a fixed groove 711 in the connecting shell 4 under the elastic force of the spring I704, so that the connection strength of the insertion shell 3 and the connecting shell 4 is ensured, when the connection part needs to be disconnected, a connector can press a pressing plate 710 downwards by hand to enable the pressing plate 710 to extrude a sliding rod 709 to move downwards, and the sliding rod 709 can longitudinally move in a sliding cavity 706, so as to drive a base plate 708 to longitudinally move in the sliding cavity 706, and then the connecting rod 705 moves down in the connecting hole 707 to drive the fixing block 703 to be separated from the fixing groove 711, so that the insertion shell 3 is convenient to take down from the connection shell 4, the connection strength of the optical fiber 1 after connection can be effectively improved, the phenomenon that the optical fiber 1 automatically falls off due to the pulling force is avoided, and the use is convenient.

Then, the upper fixing plate 1103 can be turned over by using the rotating assembly 12, the rotating plate 1203 can be turned over around the crossbar 1202 due to the fact that the crossbar 1202 in the rotating groove 1201 is in rotating fit with the through hole 1204, the upper fixing plate 1103 can be turned over conveniently, the optical fiber 1 sleeved with the protective sleeve 2 is inserted into the lower fixing plate 1102, the upper fixing plate 1103 is turned over downwards, the upper fixing plate 1103 and the lower fixing plate 1102 are closed to clamp the optical fiber 1 attached with the protective sleeve 2, the optical fiber 1 cannot be separated from the upper fixing plate 1103 and the lower fixing plate 1102 when being pulled by means of the fact that the clamping block 1104 in the upper fixing plate 1103 and the lower fixing plate 1102 is embedded, the sleeve is finally sleeved on a closed body formed by the upper fixing plate 1103 and the lower fixing plate 1102, the nut 1107 is screwed with the connecting block 1101 by rotating the nut 1107, the sleeve 1106 can fasten the upper fixing plate 1103 and the lower fixing plate 1102, and the clamping block 1104 can be tightly inserted into the clamping block 1105, the connection strength of the optical fiber 1 is further enhanced.

Finally, by using the limiting component 15, when the inserting shell 3 is not inserted into the receiving shell 4, the limiting block 1505 is positioned above the fixing block 703 by the elastic force of the second spring 1506, the fixing block 703 is limited, so that the fixing block 703 compresses the first spring 704, the rotating column 1508 moves downwards in the second through hole 1507, the left end of the seesaw 1510 is pressed down, the support block 1511 can move upwards through the lever formed by the support rod 1509 and the seesaw 1510, so that, when the plug housing 3 is just inserted into the connecting housing 4, the plug 5 will not rub against the fastening sleeve 10, when the plug housing 3 is completely inserted into the plug housing 4, the fixing block 703 is fitted into the fixing groove 711, so that the first spring 704 is restored, and under the elastic force of the first spring 704, so that the rotating post 1508 can move upwards in the second through hole 1507, thereby driving the left end of the seesaw 1510 to ascend, and then the resisting block 1511 moves downwards, so that the resisting block 1511 presses the fastening sleeve 10 downwards, and the fastening sleeve 10 has a clamping effect on the plug 5.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
