Termination Assemblies for Optical Hybrid Cables

Abstract

The invention discloses a terminal assembly for a photoelectric hybrid cable, which has a power cable and an optical fiber containing tube for accommodating optical fibers. The terminal assembly includes: an optical fiber terminal, including a pipe joint and a butt joint, and the pipe joint is used to butt the butt joint and the optical fiber receiving pipe together; a cable terminal, including an outer insulating sleeve and a metal connector, and the outer insulating sleeve Wrapped on the end of the power cable, the metal connector is electrically connected to the conductor core of the power cable; and a glove-type sealing cap, one side of which is sealed on the outer protective sheath of the photoelectric hybrid cable, and the other side has a sealed ground The first finger-shaped sleeve sleeved on the butt joint and the second finger-shaped sleeve sealedly sleeved on the outer insulating sleeve of the cable terminal. Therefore, dust and moisture can be prevented from entering the cable terminal through the gap between the cable terminal and the power cable, and dust and moisture can be prevented from entering the optical fiber terminal through the gap between the optical fiber terminal and the optical fiber receiving tube.

Description

technical field [0001] The present invention relates to a terminal assembly for connection to the end of an optical hybrid cable. Background technique [0002] In some special applications, it is necessary to use optical-electrical hybrid cables, ie, cables with both power cables and optical fibers. There is no related report in the prior art on the terminal assembly used for the connection between the optical-electrical hybrid cable and the electrical equipment and the optical equipment. [0003] In the prior art, a separate power cable is generally connected to an electrical connector of electrical equipment through a cold-shrinkable terminal. The cold-shrinkable terminal generally includes an outer insulating sleeve cold-shrunk on the end of the power cable, and a Between the stress control cone and the metal connector electrically connected to the conductor core of the power cable. [0004] In the prior art, the optical connection between two separate optical fibers is...

Problems solved by technology

In one technical solution, when splicing two optical fibers, it is necessary to connect the end of each optical fiber to an optical fiber connector, and then connect the optical fiber connectors on the two optical fibers to each other through an optical fiber adapter, so that The optical splicing between two optical fibers can be realized. This kind of optical fiber splicing method has the defects of complicated process and high cost.

In another technical solution, the optical connection between two optical fibers is achieved by fusion splicing. However, the fusion splicing method also has the disadvantages of complicated process and high cost, because it requires fiber management trays and fiber winding trays. , heat shrink tubing and many other components
