Description

A tympanic membrane re-openable fiber optic connector

Technical field

The invention relates to a connecting device for optical fiber installation, in which a V-shaped groove portion of a ferrule assembly is sealed in a tympanic membrane cavity, and a tympanic membrane is driven by a spring clip to fasten the optical fiber, and can be repeatedly opened and used, specifically A fiber optic connector in either a preset fiber or a non-preset fiber.

Background technique

At present, the quick connect device products for re-opening use mainly fix the optical fibers in three ways.

The first is to achieve the fiber butt-to-end by aligning the folded metal sheets with the two fiber ends; the second is to fix the fibers by pressing the bonded plastic blocks to achieve the fiber butt ends; the third is through The box-type gland presses the floating block to press the V-block to fix the fiber to realize the fiber butt joint. Wherein, a V-shaped groove for fiber optic docking is disposed in the V-shaped block opposite to the folded metal piece, the opposite plastic block or the floating block; and the liquid substance is dropped at the fiber end connection position of the V-shaped groove to improve the connection point Light transmittance; the action of the pressing device is to reduce the gap of the V-groove by pressing the folded metal piece or the folded plastic piece or the rolling floating block to press the aligned fiber to realize the butt end of the two fibers. .

In the fixing of the optical fiber, in the fixing method of the first optical fiber, when the metal piece is pressed in the fixing mechanism, the returning groove must be arranged on the opposite side of the V-shaped groove to prevent the optical fiber from being detached, and the optical fiber gap is controlled by the folded metal piece. The space in the cavity guarantees the opening degree, that is, the V-groove gap (penetration gap), which brings great manufacturing difficulty and low yield; in the second fiber fixing mode, the plastic V-shaped block alignment mechanism is locked. When the fiber is tight, the optical fiber that is pressed and pressed in the V-shaped groove by the gland is affected by the gap drift of the gland by the rotation pressing method. The direction of the fiber is often not perpendicular to the V-groove, and the accuracy of the alignment accuracy of the fiber is incorrect. The fiber-optic connection loss of the two-connected fiber is increased; when the fiber-optic channel of the plastic V-block alignment mechanism is used repeatedly, the special key is used to open the pressure block, and the opening requirement of the top opening requires strict precision requirements, and the product is manufactured in batches. It is difficult, the yield is low, and the plastic debris generated by the friction during the opening process pollutes the connection point. When repeated use, it affects the light passing, which causes the quality of the connection to decrease. Some plastic V-block alignment mechanisms are in the initial state. In the free state, the fiber needs to open the V-shaped block channel when it penetrates, and there is matching liquid adsorption inside, which causes the fiber penetration resistance to increase when the fiber penetrates into the top open V-groove, and the probability of false docking increases in the project, and the sharpness is sharp. The fiber-cut end face is easy to scratch the V-shaped block, causing debris to contaminate the connection point, causing the connection failure; in the third fiber fixing mode, since the floating block is a sill-type design, the floating block is plasticized when it is pressed by the cover. The effect of deformation is to sway downward while rotating the fiber, so that the fiber in the V-groove is turbulent, and the direction of the fiber is not perpendicular to the V-groove, and the alignment accuracy of the splicing fiber is deteriorated, and the connection loss is increased. Since the alignment accuracy is affected by the material and the interference accuracy, the dispersion accuracy is large, resulting in poor repeatability of the fiber connection.

The common disadvantage of the first two types of fiber fixing methods is that the V-shaped groove portion cannot be sealed, and no matching night storage chamber is provided, so that the matching liquid for the connection in the V-shaped groove is easily contaminated and lost, directly affecting the connection life, and the third Although it can have a certain sealing effect in the working state, it cannot be sealed before use, and the gland which is opened when it is repeatedly used is easy to slip, and is easily contaminated by the environment during repeated use.

Beneficial effect

Compared with the prior art, the present invention has the following advantages:

In the alignment fixing mechanism of the optical fiber connector of the present invention, the pressing of the two butt fibers is to hold the case and the cover together by simple components such as a locking member such as a spring clip or a sleeve, and drive the tympanic membrane to reduce V. The space between the groove and the tympanic membrane is used to press the fiber in the V-shaped groove to achieve compaction. In the open state or the working compression state, the V-shaped groove cavity of the connecting fiber is sealed, and the fiber is connected. No matter how bad the construction or working environment, it can ensure the cleanliness of the connection point, avoid the pollution and erosion, and will not pollute the connection point when the re-opening of the gland is repeated, which greatly improves the success of the fiber connection. The rate increases the stability of repeated use and prolongs the service life. At present, no product has been designed with this sealing method.

In the alignment fixing mechanism of the optical fiber connector of the present invention, the box body and the box cover are tightly held together by the spring clip, and the pressing force of the connecting fiber in the V-shaped groove is transmitted through the eardrum, and the circumference of the eardrum is passed. The floating rib is connected to the body of the box, so the deformation of the tympanic membrane is always perpendicular to the V-shaped groove after being pressed, and the cylindrical optical fiber is uniformly pressed in three equal directions in the V-shaped groove without setting the opposite side of the V-shaped groove. The cage is retracted to prevent the fiber from being detached, and the existing pressure-receiving method always overcomes the influence of the torque generated by the fiber, thereby improving the centering accuracy.

The optical fiber splicing force of the invention is stable during the action of the fastening force, and the connecting fiber in the V-shaped groove is not eccentric and misaligned due to the turbulence, and the deformation is uniform during the pressing, thereby ensuring the same pressing force of the two butt fibers, and achieving reliable performance. Docking.

The optical fiber connector of the present invention is only used to cancel the pressing force applied to the eardrum due to the top opening of the cover. It is only necessary to squeeze the cover to restore the tympanic membrane to a free state, and the opening requirement does not require much precision. , reducing manufacturing difficulty and facilitating mass production.

The optical fiber connector of the invention adopts a floating tympanic membrane, and when the tympanic membrane is in a non-operating state (ie, when the fiber is inserted), the tympanic membrane is in a freely open state, and an open fiber channel is formed between the V-shaped body groove in the ferrule assembly, and the fiber enters the V. When the groove is used, the pressure block is not required to be opened first, so that the difficulty of threading is greatly reduced, and the damage of the V-shaped groove when the sharp fiber cutting surface is worn is reduced, the fiber penetration pollution is reduced, and the success rate of the connection is improved.

The two ends of the optical fiber connection sub-casing body of the invention are respectively provided with matching liquid chambers, and when used repeatedly, there can be sufficient matching liquid to ensure the quality of the multiple connections, and the matching liquid is prevented from being lost; at the same time, the redundant matching liquid at the fiber insertion opening can The closed connection point and the external environment improve the anti-fouling ability of the matching point matching liquid and improve the service life.

The tympanic membrane of the invention has a thin thickness and is a primary color plastic material. Compared with the opaque folded metal or the thick plastic gland, the light transmission performance is better, and the infrared light is introduced into the optical fiber through the casing after the connection is completed. Open the slot to observe the connection quality of the connection point, free from ambient light interference.

After the fiber splicing of the invention is completed, the fiber has a redundant fiber tail bend reserved in the splicing, and the redundant fiber tail bend can protect the fiber from being pulled off to some extent when the splicing cable is deformed by external force. It improves the adaptability of the product, especially for quality sub-cables.
