Terminal assembly for photoelectric hybrid cable

Abstract

The invention discloses a terminal assembly for a photoelectric hybrid cable. The photoelectric hybrid cable comprises an electric power cable and an optical fiber accommodation pipe for accommodating optical fibers. The terminal assembly comprises an optical fiber terminal, an electric cable terminal, and a glove-type seal cap. The optical fiber terminal comprises a pipe joint and a butt joint pipe, wherein the pipe joint is used for connecting the butt joint pipe and the optical fiber accommodation pipe in a butt joint manner. The electric cable terminal comprises an external insulation sleeve and a metal connection piece, wherein the external insulation sleeve wraps a tail end of the electric power cable, and the metal connection piece is electrically connected to a conductor core of the electric power cable. One side of the glove-type seal cap sleeves an outer protection sleeve of the photoelectric hybrid cable in a sealing manner, and the other side of the glove-type seal cap has a first finger-shaped sleeve and a second finger-shaped sleeve, wherein the first finger-shaped sleeve sleeves the butt joint pipe in a sealing manner, and the second finger-shaped sleeve sleeves the external insulation sleeve of the electric cable terminal in a sealing manner. Therefore, dust and moisture are prevented from entering the electric cable terminal through the gap between the electric cable terminal and the electric power cable and are prevented from entering the optical fiber terminal through the gap between the optical fiber terminal and the optical fiber accommodation pipe.

Description

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

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
