Background technology

Fiber adapter is also the joints of optical fibre, and it is to be connected by adapter by its internal split coupling between fiber active linker centering connection member, optical fiber to be, to ensure the highest switching performance between optical patchcord.Fiber adapter has SC adapters, FC adapters, point of ST adapters.Wherein, the SC in SC adapters represents Standard Connector.SC adapters are standard square joints, using engineering plastics, with high temperature resistant, it is not easy to oxidizing advantages.

But domestic existing SC adapters can only pass through frock, the complicated procedures of forming such as tool weld to complete SC adapters high technology ceramics or copper sleeve, and adapter shell and inner sleeve are assembled, the assembling process makes SC adapter quality unstable, there is waste of manpower, man-hour, and this SC adapters spare and accessory parts are more, add the die sinking cost of spare and accessory parts, simultaneously, it once assembly be completed, the problem of can't resolve dismounting.

The content of the invention

It is an object of the invention to provide a kind of rotary adapter, its low cost, assembling is easy, and convenient disassembly can save labour, reduce work hours, and improves production efficiency, enhancing reliability and tensile strength.

In order to achieve the above object, the present invention has following technical scheme：

A kind of rotary adapter of the present invention, including porcelain bushing, left outside shell, right casing, the first groove is respectively equipped with described two corresponding angles of left cover top portion, second groove, first arcwall face, second arcwall face, first arcwall face is located at the end of the first groove, second arcwall face is located at the end of the second groove, left cover top portion two other diagonally should on be respectively equipped with the first raised line, second raised line, it is the left passage of placing ceramic sleeve pipe in the middle part of the left outside shell, the 3rd groove is respectively equipped with described two corresponding angles in right casing bottom, 4th groove, the 3rd raised line is respectively equipped with two other corresponding angles of right casing bottom, 4th raised line, 3rd arcwall face, 4th arcwall face, 3rd arcwall face is located at the end of the 3rd raised line, 4th arcwall face is located at the end of the 4th raised line, it is the right passage of placing ceramic sleeve pipe in the middle part of the right casing.

Wherein, the left outside shell is the integrative-structure of compression molding, and right casing is the integrative-structure of compression molding.

Wherein, the first groove of the left outside shell, the second groove, the first raised line, be equipped with tooth bar on the second raised line, the groove of right casing the 3rd, the 4th groove, the 3rd raised line, be equipped with tooth bar on the 4th raised line.

The advantage of the invention is that：

1. the present invention is solved by frock, the complicated procedures of forming such as tool completes to assemble problem, realize it is easy for installation, fast, and quick detachable.

2. the present invention can save labour, reduce work hours, improve production efficiency, the present invention need not be welded, and enhance reliability and tensile strength, Stability Analysis of Structures.

3rd, the present invention is simple in construction, is only made up of porcelain bushing, left outside shell, three parts of right casing.
