Detailed ways

In the embodiment of this application, for the convenience of description, the end refers to the end of the fiber optic connector used to connect with the fiber optic adapter, the tail refers to the end where the continuous optical cable is inserted, and the axial direction refers to the overall extension of the fiber optic connector direction.

The present application will be described in further detail below in conjunction with accompanying drawings 1-8.

The embodiment of the present application discloses a clamshell optical fiber connector. Referring to Figure 1, the clamshell fiber optic connector includes a connecting body 1, an extension core 2, a rotating flip cover 3 and a coupling cap 4. The connecting body 1 has a cavity for the axial installation of the splicing core 2, and the rotating flip cover 3 rotates Connected to the tail of the connection body 1 and used to cooperate with the connection body 1 to clamp the optical cable, the coupling cap 4 is sleeved on the outside of the connection body 1 and used to cooperate with the connection body 1 to form a corresponding structure connected with an optical fiber adapter. After the fixed-length cable sheath is stripped off, the optical cable passes into the optical fiber connector through the tail of the connecting body 1, and the continuous optical fiber after stripping the cable sheath is passed into the continuous core 2, and is connected with the continuous core 2. The pre-embedded fiber optic connectors are connected to each other. Wherein, when the rotating cover 3 is closed on the connecting body 1, the rotating cover 3 matches with the connecting body 1 to clamp the optical cable; Disassemble.

Referring to Fig. 2, in general, the splicing core 2 includes a base 21 for carrying the pre-embedded optical fiber 26 and the splicing optical fiber and a cover plate 22 covered on the base 21, and one end of the base 21 is provided with a The other end of the ceramic ferrule 23 for docking with external equipment is provided with a connecting pipe 24, and the center of the base 21 is provided with a splicing groove 25 for connecting the pre-embedded optical fiber 26 and the spliced optical fiber, and the pre-embedded optical fiber 26 Embedded in the ceramic ferrule 23 and passed through the splicing groove 25, the splicing optical fiber passes through the connecting tube 24 into the inside of the splicing core 2 and passes through the splicing groove 25, the pre-embedded optical fiber 26 is connected to the splicing groove 25. The axial end surfaces of the optical fibers abut against each other in the splicing groove 25 . The cover plate 22 is used to cover the base 21 and cooperate with the base 21 to clamp the pre-embedded optical fiber 26 and the continuous optical fiber to prevent mutual movement of the two.

The extension core 2 is provided with a lock sleeve 5 that slides along the extension direction of the extension fiber, and the lock sleeve 5 slides outside the extension core 2 to have a locked state for clamping the extension fiber and the pre-embedded optical fiber 26 And loosen the unlocking state of connecting optical fiber and pre-embedded optical fiber 26. As a specific embodiment, at least one side of the base 21 and the cover plate 22 facing away from each other is provided with a convex strip 27. When the lock sleeve 5 slides to the outside of the convex strip 27, the base 21 and the cover plate 22 are enlarged. To achieve the effect of interference fit with the locking sleeve 5, the cover plate 22 exerts a downward force on the base 21 to realize the fixing of the continuous optical fiber and the embedded optical fiber 26, that is, the locking sleeve 5 enters the locked state. Generally speaking, the lock sleeve 5 in the locked state needs to be located in the outer circumference of the joint between the continuous optical fiber and the pre-embedded optical fiber 26, so as to ensure that the joint has a good compression effect, so as to ensure that the continuous optical fiber can be used in various In complex scenarios (such as high and low temperature environments, and external forces pulling optical fibers, etc.), it can still pass the transmission test well, so that various transmission parameters can meet the required requirements.

Referring to Figures 2 and 3, on this basis, at least one linkage plate 51 extending toward the tail of the main body 1 is fixedly connected to the lock sleeve 5, and the end of the linkage plate 51 away from the lock sleeve 5 is provided with a Through the drive column 52 on the side of the connection body 1, the connection between the drive column 52 and the linkage plate 51 is reinforced by a connected reinforcing piece 53. The relief area 11 through which the column 52 passes, when the lock sleeve 5 slips on the extension core 2 , the driving column 52 connected to the lock sleeve 5 is synchronously driven to slide synchronously in the relief area 11 . There are connecting plates 31 extending to both sides of the connecting body 1 on both sides of the rotating flip cover 3, and the connecting body 1 is provided with a rotating column 12 passing through the connecting plate 31 to realize the rotational connection of the connecting plate 31 relative to the connecting body 1, and the connecting plate 31 is located at one end close to the rotating column 12 and is provided with an arc-shaped groove 32 for the driving column 52 to pass through. During the process of rotating the flip cover 3, the driving column 52 can be limited by the arc-shaped groove 32 and give way.

At one end, in the locked state, the arc-shaped groove 32 extends along the direction close to the tail of the connecting body 1, and the distance between it and the rotating post 12 (ie the rotating place of the connecting plate 31) decreases gradually during the extending process. In this embodiment, when the flip cover 3 is closed and closed on the connection body 1, the driving column 52 will be driven and guided by the arc groove 32 and gradually approach the end of the optical fiber connector. When the rotating flip cover 3 is flipped open, the driving column 52 will gradually approach the position where the rotating column 12 is located under the driving and guiding action of the arc groove 32 . Therefore, when the rotating cover 3 is closed, that is, in the locked state, the lock sleeve 5 will be located on the side close to the end, and when the rotating cover 3 is opened, that is, in the unlocked state, the lock sleeve 5 will be correspondingly located near the end. One side of the tail, therefore, the locking sleeve 5 is set on the side close to the end to lock the extension core 2, and then the lock sleeve 5 is driven synchronously to clamp the extension when the flip cover 3 is clamped to clamp the optical cable. Optical fiber and pre-embedded optical fiber 26.

Under the effect of this setting method, it can be seen that the locking sleeve 5 will be located on the side close to the ceramic ferrule 23 when it is in the locked state, so the length of the pre-embedded optical fiber 26 can be correspondingly reduced so that the pre-embedded optical fiber 26 corresponds to the position where the lock sleeve 5 is connected to the connecting optical fiber. At the same time, after multiple experiments by the applicant, it has also been found that the shorter the embedded optical fiber 26, the easier it is to improve the transmission performance of the optical fiber connector, so that various parameters such as insertion loss and return loss can be better than those in the locked state located near the tail. implementation. Therefore, under the premise of meeting the transmission parameters and the same manufacturing process, the shorter pre-embedded optical fiber 26 can make the products produced have a higher qualification rate, while the longer pre-embedded optical fiber 26 can meet the requirements of transmission. parameters, but the overall pass rate is low.

The setting of the relief groove 17 is required according to the length of the linkage plate 51 and the overall length of the optical fiber connector. By extending the length of the linkage plate 51, the relief groove 17 can be correspondingly reduced or removed. . Wherein, the positions of the relief groove 16 and the relief groove 17 are associated with the number of linkage plates 51, when there is only one linkage plate 51 on the locking sleeve 5, the relief groove 16 and the relief groove 17 are only arranged on the On the same side of the connecting body 1 , when two linkage plates 51 are arranged symmetrically on the locking sleeve 5 , the escaping groove 16 and the relief groove 17 are correspondingly arranged on both sides of the connecting body 1 .
