Chuck used for optical fiber joints

Abstract

The invention discloses a collet applied for an optical fiber connector. The collet consists of a body with an optical fiber hole, and one end of the body is separated into at least two lock clamps by a lock groove, the surface of the lock clamp is a helicoid which is the helicoid with equal conicity. The other end of the cylinder body is provided with a rear part, and the center of the rear part is also provided with an optical fiber hole. Compared with the prior art, the collet of the invention is provided with at least two lock clamps in the front of the body, the surfaces of the lock clamps are helicoids, and a trap step is formed among the lock clamps. When the collet of the invention is arranged in the optical fiber connector, the helicoid in the front of the collet and a tapering step helicoid in a sleeve of the optical fiber connector rotate, and the two helicoids are engaged with each other automatically, thus effectively preventing the rotation caused during the connection process of the optical fiber; simultaneously, the optical fiber hole in the collet is has the guiding function, thus ensuring the surface of the optical fiber to be undamaged during the connection process. On the other hand, the invention avoids the manual intervention and is favorable for implementing the micromation of the whole structure.

Description

technical field [0001] The invention relates to a component for an optical fiber connector, in particular to a chuck for an optical fiber connector. Background technique [0002] At present, the installation of optical fiber cables for optical fiber connection sub-products mainly uses special tools to push the bare fiber by pressing the bent optical fiber sheath, so as to ensure the bonding of the optical fiber surface, and then rely on the single-point clamping device set in the sleeve Tight, the special tool cannot guarantee sufficient bonding force of the optical fiber, especially when the surface of the bare fiber is defective, it is even more difficult to ensure the true bonding of the fiber surface, and it cannot effectively prevent the rotation of the optical fiber cable. When an accidental force is applied during installation or use, it cannot Fully protect bare fibers. There is also a collet used for the connector of the optical fiber ribbon, which is provided with...

There is also a collet used for the connector of the optical fiber ribbon, which is provided with a keyway on the cylinder of the collet. This structure needs to be aligned manually, and the position of the keyway cannot be automatically aligned to realize the anti-rotation function. Ease of miniaturization
