Description
Technical field
The present invention relates to joints of optical fibre field, particularly relate to a kind of joints of optical fibre device for clamping and rotating.
Background technology
The joints of optical fibre, also known as fiber adapter, are the devices removably connected between optical fiber and optical fiber
Part, it is two fiber end face precision docking so that the output energy of launching fiber can be maximum
Being coupled in optical fiber of degree, and make the impact on optical link minimum.Optical fiber generally used now
Adapter is made up of ceramic lock pin based on zirconium oxide, by manufacturing one and fibre diameter in a cylinder
Close circular hole accommodates the connection of optical fiber.And wherein, hole is concentricity with the distance at the center of cylindrical.
Concentricity meeting strong influence is to the performance of the joints of optical fibre, the not only size of concentricity, its angle side
To the performance also influencing whether the joints of optical fibre.
Joints of optical fibre concentricity detects and generally uses two ways: contactless and contact, uses
Non-contact detection is due to detection speed, and lossless, so being relatively good solution.
But the clamp precision of lock pin is required higher by non-contact detection means, and angle and spatial deviation can be right
Measure and cause the biggest impact.
The most the most frequently used mode has above V groove the form using roller or rotation depression bar to drive
Lock pin cylindrical rotates.The technology of this drive cylindrical can only apply to the optical fiber of 0.9mm optic cable diameter
Adapter and the detection of naked lock pin, in the industry cycle in the most frequently used 2.0mm and 3.0mm cable sheath straight
In the case of footpath, owing to the stress of optical cable itself is excessive, use the means driving cylindrical cannot drive 2.0,
3.0 cable sheath optical cables, and also cannot be carried out detecting the joints of optical fibre assembled.A direct rotary simultaneously
