Description

Structure for preventing FC optical fiber connector lock pin from offsetting

Technical Field

The invention relates to the field of optical fiber equipment, in particular to a structure for preventing an insertion core of an FC optical fiber connector from offsetting.

Background

An optical fiber splice, which is an end device for optical fibers, permanently or separably joins two optical fibers together and has a splicing portion of a protective member. Common fiber splices are FC splices, SC splices, and ST splices. The FC joint is a circular threaded joint and a metal joint, and the pluggable frequency of the metal joint is more than that of plastic. Typically telecommunications networks employ a nut which is screwed onto the adapter.

In the prior art, after the optical fiber connector FC/PC0.9 parts are assembled, the contact portion of the spring is deformed and distorted under the action of gravity and thrust, so that the fiber-containing ferrule deviates from the center line, and in the process of connecting two lines, the fiber-containing ferrule deviates transversely, thereby affecting the data transmission of the two lines. In the prior art, a hard metal gasket is arranged between the contact surfaces of the stop ring and the spring, and the design mode not only can easily generate displacement, but also can not fundamentally prevent the spring from deforming.

Disclosure of Invention

In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a prevent structure of FC fiber connector lock pin skew, includes joint, spring and stereoplasm gasket, the retaining ring is established to the outside cover that connects, the long slot hole of intercommunication retaining ring hole is seted up to the shell internal symmetry that connects, place the spring in the hole of retaining ring, the one end fixed connection stereoplasm gasket that the spring is relative with the long slot hole, the stereoplasm gasket is established to the ring form, and the inboard edge of stereoplasm gasket is established to the inboard edge that exceeds the spring, and the outside edge of stereoplasm gasket is established to the outside edge coincidence with the spring, the stereoplasm gasket is located the inboard fixed connection slender pole of spring, the tip of slender pole stretches into the inside of long slot hole.

Preferably, the spring and the hard gasket are inserted into the stem insert with the tail handle.

Preferably, the number of the long slotted holes is two or three, and the number and the positions of the thin rods correspond to those of the long slotted holes.

Preferably, the diameter length of the thin rod is equal to the distance between the inner side edge of the hard gasket and the outer side edge of the spring, the end part of the thin rod is positioned in the long slotted hole when the spring is in an extension state and a compression state, and the side edge of the thin rod contacts the inner spring body of the spring.

The invention has the following beneficial effects: this prevent structure of FC fiber connector lock pin skew can prevent that the whole distortion that produces of spring to prevent that the lock pin from producing the skew, stereoplasm gasket and slender pole reasonable in design can not occupy the lock pin usage space moreover, can not hinder the lock pin motion yet, and is more accurate when making two articulate, and signal loss is littleer, and data transmission is more stable.
