Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connectors, in particular to an optical fiber quick connector with a fiber threading and guiding function. Background Art

[0002] Fiber optic connectors are devices that make detachable (movable) connections between optical fibers. They precisely connect the two end faces of optical fibers so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] Among them, the existing fiber optic quick connector reduces the difficulty of assembly and improves the one-time assembly pass rate. Generally, an auxiliary bracket is set on the connector body, and the auxiliary bracket is used to cooperate with the cable clamp to ensure the one-time pass rate of optical fiber docking. However, during the assembly process of the existing fiber optic quick connector, the auxiliary bracket needs to be installed in the connector body first, which not only increases the number of parts of the entire fiber optic quick connector, reduces the assembly efficiency, but also increases the manufacturing cost.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0032] like Figure 1-10 As shown, an optical fiber quick connector with a fiber insertion and guiding function includes a connector body 1, a core 2 pre-buried in the connector body 1, and a cable clamp 3 for fixing an optical fiber cable. A fiber insertion hole 104 for inserting an external optical fiber is formed on the connector body 1, and the cable clamp 3 is inserted into the connector body 1 to connect the optical fiber to the core 2.

[0033] Specifically, the cable clamp 3 has an auxiliary plug-in plate 101 extending along the direction of optical fiber insertion, and a fixing buckle 102 for positioning the optical fiber is formed on the auxiliary plug-in plate 101, and a sliding groove 103 for inserting the auxiliary plug-in plate 101 is formed on the connector body 1. The auxiliary plug-in plate 101 is inserted into the connector body 1 along the sliding groove 103 so that the optical fiber is inserted into the fiber insertion hole 104 and docked with the ferrule 2.

[0034] During the optical fiber connection process, the optical fiber cable is first fixed on the cable clamp 3, and the exposed bare optical fiber is placed in the fixing buckle 102, and then the auxiliary plug-in plate 101 is placed in the sliding groove 103, so that the entire cable clamp 3 slides on the connector body 1, and the bare optical fiber is placed in the fiber insertion hole 104, so as to achieve docking with the ferrule 2 embedded in the connector body 1, which can not only greatly improve the one-time assembly qualification rate, but also compared with the prior art of setting an auxiliary structure on the connector body 1, the structure is simpler, and there is no need to add redundant parts, thereby improving assembly efficiency and reducing manufacturing costs.

[0035] like Figures 1 to 6 As shown, a further explanation of the implementation of the auxiliary plug-in board 101 in this embodiment is provided. A first engaging protrusion 201 is formed at the bottom of the auxiliary plug-in board 101, and a first engaging groove 202 for the first engaging protrusion 201 to be placed is formed on the connector body 1.

[0036] During the optical fiber connection process, the auxiliary plug-in plate 101 is inserted into the connector body 1 along the sliding groove 103. When the optical fiber is inserted into the fiber insertion hole 104, the first clamping protrusion 201 at the bottom of the connector body 1 will slide into the first clamping groove 202 on the connector body, thereby fixing the entire cable clamp 3 in the connector body 1, ensuring the stability of the connection between the cable clamp 3 and the connector body 1.

[0037] Furthermore, a disengagement deformation groove 203 is formed between the auxiliary plug plate 101 and the cable clamp 3 , and the cable clamp 3 is bent along the disengagement deformation groove 203 to enable the first clamping protrusion 201 to disengage from the first clamping groove 202 .

[0038] When the optical fiber needs to be pulled out, since there is a gap between the connection parts of the auxiliary plug-in plate 101 and the cable clamp 3 and a disengagement deformation groove 203 is formed, the cable clamp 3 can be bent toward the auxiliary plug-in plate 101, so that the first clamping protrusion 201 is disengaged from the first clamping groove 202, which makes it easier to disassemble the cable clamp 3 and improves the user's convenience.

[0039] A positioning groove 105 for inserting the optical fiber is formed on the fixing buckle 102. The optical fiber is inserted into the positioning groove 105. The positioning groove 105 can limit the height of the optical fiber and prevent it from shifting to the left or right, thereby improving the one-time assembly qualification rate.

[0040] like Figure 4 As shown, as an example, a guiding arc surface is formed on the insertion section of the positioning groove 105 to make it easier for the optical fiber to enter the positioning groove 105.

[0041] Preferably, the auxiliary plug-in plate 101 and the fixing buckle 102 arranged on the auxiliary plug-in plate 101 are integrally formed on the cable clamp 1, thereby improving the overall structural strength.

[0042] Preferably, the fiber insertion holes 104 tend to converge along the optical fiber insertion direction and form a guide channel 106. The guide channel 106 can guide the optical fiber, thereby further improving the one-time assembly qualification rate.

[0043] like Figures 1 to 6 As shown, further explanation of the cooperation between the cable clamp 3 and the connector body 1 in this embodiment is provided. First sliding protrusions 309 are formed on both sides of the cable clamp 3, and a guide groove 403 for the first sliding protrusion 309 to be inserted is formed on the connector body 1, which not only improves the stability of the cable clamp 3 during the insertion process, but also further improves the one-time assembly qualification rate of the optical fiber connection.

[0044] Furthermore, a fixing groove 401 for fixing the optical fiber cable is formed on the cable clamp 3, and a blocking cover 402 for closing the fixing groove 401 is rotated on the fixing groove 401, and a second sliding protrusion 310 is formed on the side of the blocking cover 402. When the blocking cover 402 is in a closed state, the second sliding protrusion 310 is inserted into the guide groove 403. The blocking cover 402 can not only cover the fixing groove 401 to limit and fix the cable, but also the second sliding protrusion 310 on the blocking cover 402 can slide in the guide groove 403, thereby improving the sliding stability of the cable clamp 3 and improving the one-time assembly pass rate of the optical fiber connection.

[0045] Specifically, a connecting protrusion 404 is formed on the side of the cable clamp 3, and a connecting groove 405 for the connecting protrusion 404 to be placed is formed on the second sliding protrusion 310, and the connecting protrusion 404 is placed in the connecting groove 405, so that the blocking cover 402 is covered on the fixed groove 401, and the fixed groove 401 is formed with a first squeezing protrusion 406 for squeezing the two sides and the bottom of the optical fiber cable, and the blocking cover 402 is formed with a second squeezing protrusion 407 for squeezing the top of the optical fiber cable, and the first squeezing protrusion 406 and the second squeezing protrusion 407 are used to cooperate with each other to squeeze and limit the cable from the periphery, and the blocking cover 402 is fixed on the fixing groove 401 through the connection groove 405 and the connection protrusion 404, thereby greatly improving the stability of the cable fixation.

[0046] like Figure 7 , Figure 8 , Fig.10 As shown, as a further explanation of the installation of the ferrule 2 in this embodiment, a mounting seat 301 is provided in the connector body 1, and a connecting channel 302 connecting the ferrule 2 and the optical fiber is formed on the mounting seat 301, and a first blocking cover 303 for abutting and fixing the ferrule 2 and a second blocking cover 304 for abutting and fixing the optical fiber are provided on the mounting seat 301. A clamping steel sheet 305 is sleeved on the outer periphery of the mounting seat 301, and a partition notch 306 is formed on the clamping steel sheet 305, and the clamping steel sheet 305 is divided into a first clamping portion 307 and a second clamping portion 308. The first clamping portion 307 clamps the first blocking cover 303, and the second clamping portion 308 clamps the second blocking cover 304.

[0047] Among them, the first blocking cover 303 and the second blocking cover 304 respectively squeeze and fix the core 2 and the optical fiber, and a partition notch 306 is set on the clamping steel sheet 305 to separate the clamping steel sheet 305 into a first clamping portion 307 and a second clamping portion 308. The first clamping portion 307 and the second clamping portion 308 squeeze the first blocking cover 303 and the second blocking cover 304 respectively, thereby applying different locking forces to the first blocking cover 303 and the second blocking cover 304, thereby improving the stability of the connection between the core 2 and the optical fiber and making it easier to disassemble the optical fiber.

[0048] When the optical fiber needs to be removed, the unlocking block can be inserted between the mounting seat 301 and the first and second blocking covers 303 and 304 , thereby opening the clamping steel sheet 305 so that the optical fiber can be pulled out from the connecting channel 302 .

[0049] like Fig. 9As shown, in some other embodiments, a connection space 501 for inserting the cable clamp 3 is formed on the connector body 1, and a flip cover 502 for shielding the connection space 501 is provided on the connector body 1, second snap-fitting protrusions 503 are formed on both sides of the connector body 1, and a second snap-fitting groove 504 for inserting the second snap-fitting protrusion 503 is formed on the flip cover 502, and when the second snap-fitting protrusion 503 is inserted into the second snap-fitting groove 504, the flip cover 502 is fixed to the connector body 1.

[0050] In addition, a limiting slot 505 is formed on the flip cover 502. When the flip cover 502 is covered on the connection space 501, the fiber optic cable is inserted into the limiting slot 505. When the flip cover 502 is covered on the connection space 501, the fiber optic cable is inserted into the limiting slot 505, thereby avoiding left and right deviation of the fiber optic cable and further improving the reliability of the connection.

[0051] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
