Description

Technical Field

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

[0002] Optical fiber, short for optical fiber, is a fiber made of glass or plastic that conducts light based on the principle of total internal reflection of light. Optical fiber is widely used in communications due to its wide bandwidth, low loss, light weight, strong anti-interference capabilities, and fast transmission speeds. When connecting and transmitting optical fibers, fiber optic connectors are often required to achieve fiber splitting and other line layouts. Fiber optic connectors can permanently or releasably connect two optical fibers and provide a protective connection.

[0003] In the prior art, when using a fiber optic connector to connect optical fibers, a fiber optic ceramic ferrule is usually used to fix the optical fiber, and then the fiber optic ceramic ferrule is connected through the connector. However, when the existing fiber optic connector is used to fix the fiber optic ceramic ferrule, the fixing effect is poor, which can easily cause the fiber optic ceramic ferrule to loosen, resulting in the docking position of the two optical fibers being offset or separated, affecting signal transmission. Utility Model Content

[0004] The utility model aims to solve the problem of preventing the optical fiber ceramic ferrule from loosening in the prior art and proposes an optical fiber quick connector.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

Both the main connector and the secondary connector are provided with a positioning hole for positioning the optical fiber ceramic ferrule and a tapered hole for inserting the optical fiber ceramic ferrule into the positioning hole. Both the main connector and the secondary connector are provided with a clamping assembly for clamping the optical fiber ceramic ferrule. The clamping assembly includes a clamping piece that cooperates with the tapered hole to clamp the optical fiber ceramic ferrule and two slide grooves for sliding the clamping piece. The ends of the main connector and the secondary connector away from the positioning hole are provided with a pressurizing assembly that applies a thrust to the clamping piece. The main connector and the secondary connector are connected by a connecting ring.

[0007] In some embodiments, the sliding groove is provided on the inner wall of the main joint or the auxiliary joint, and the surface of the clamping member is provided with an opening for deforming the clamping member.

[0008] In some embodiments, the pressurizing assembly includes a threaded barrel threadedly connected to the inside of the main joint or the auxiliary joint and a top ring fixedly connected to the inner end of the threaded barrel, and a rotating handle is fixedly connected to the outer end of the threaded barrel.

[0009] In some embodiments, the main connector is fixedly connected to one end near the positioning hole with a guide bucket for inserting the optical fiber ceramic ferrule into the positioning hole, and the auxiliary connector is provided with a step hole at one end near the positioning hole.

[0010] In some embodiments, a connecting rod is rotatably connected to the surface of the connecting ring, and a connecting column that is clamped to the connecting rod is fixedly connected to the surface of the auxiliary joint.

[0011] In some embodiments, a rubber ring is respectively provided inside the two handles.

[0012] Compared with the prior art, the present invention provides an optical fiber quick connector with the following beneficial effects.

[0013] 1. The utility model provides a clamping assembly so that the clamping member slides in the slide groove. Under the cooperation of the clamping member and the tapered hole, the clamping member is squeezed and deformed through the opening, thereby clamping and fixing the optical fiber ceramic ferrule to prevent the optical fiber ceramic ferrule from shifting.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A fiber optic quick connector includes a main connector 1 and a sub-connector 2. Both the main connector 1 and the sub-connector 2 are provided with a positioning hole 3 for positioning the optical fiber ceramic ferrule and a tapered hole 4 for inserting the optical fiber ceramic ferrule into the positioning hole 3. The length of the positioning hole 3 in the main connector 1 is greater than the length of the positioning hole 3 in the sub-connector 2. Both the main connector 1 and the sub-connector 2 are provided with a clamping assembly 5 for clamping the optical fiber ceramic ferrule. The clamping assembly 5 includes a clamping piece 502 that cooperates with the tapered hole 4 to clamp the optical fiber ceramic ferrule and two slide grooves 501 for sliding the clamping piece 502. The slide groove 501 is provided on the inner wall of the main connector 1 or the sub-connector 2. The clamping piece 502 is slidably connected to the inner walls of the two slide grooves 501. The surface of the clamping piece 502 is provided with a tapered surface. The surface of the clamping piece 502 is provided with an opening 503 for deforming the clamping piece 502 and an arc surface for cooperating with the optical fiber ceramic ferrule.

[0024] It can be understood that the clamping member 502 is slid toward the tapered hole 4 through the slide groove 501. Under the cooperation of the clamping member 502 and the tapered hole 4, the clamping member 502 is squeezed and deformed through the opening 503, thereby clamping and fixing the optical fiber ceramic ferrule to prevent the optical fiber ceramic ferrule from shifting. By inserting two optical fiber ceramic ferrules into the positioning hole 3, the optical fiber ceramic ferrules are easily connected.

[0025] Specifically, a pressure-applying assembly 6 for applying thrust to the clamping member 502 is provided at one end of the main joint 1 and the auxiliary joint 2 away from the positioning hole 3. The pressure-applying assembly 6 includes a threaded barrel 601 threadedly connected to the inside of the main joint 1 or the auxiliary joint 2 and a top ring 602 fixedly connected to the inner end of the threaded barrel 601. A turning handle 603 is fixedly connected to the outer end of the threaded barrel 601. The surface of the turning handle 603 is provided with anti-slip grooves. A connecting ring 7 is fixedly connected to the surface of the main joint 1. The main joint 1 and the auxiliary joint 2 are connected via the connecting ring 7.

[0026] It can be understood that by rotating the handle 603, the threaded barrel 601 is driven to rotate, so that the threaded barrel 601 drives the top ring 602 to apply pressure to the clamping member 502, and the optical fiber ceramic ferrule is clamped by the clamping member 502. By inserting the auxiliary connector 2 into the connecting ring 7, the main connector 1 and the auxiliary connector 2 are preliminarily connected.

[0027] Specifically, the main connector 1 is fixedly connected to the end near the positioning hole 3 with a guide bucket 8 for inserting the optical fiber ceramic ferrule into the positioning hole 3, and the auxiliary connector 2 is provided with a step hole 9 at the end near the positioning hole 3.

[0028] It can be understood that by providing the guide bucket 8, it is convenient to insert the optical fiber ceramic ferrule in the auxiliary connector 2 into the positioning hole 3 in the main connector 1 for docking.

[0029] Specifically, the surface of the connecting ring 7 is rotatably connected to a connecting rod 10, and the surface of the auxiliary joint 2 is fixedly connected to a connecting column 11 that is engaged with the connecting rod 10. There are two groups of connecting rods 10, and they are symmetrically arranged on the surface of the main joint 1. The surfaces of the two connecting rods 10 are provided with a slot that cooperates with the connecting column 11.

[0030] It is understandable that by rotating the connecting rod 10, the connecting rod 10 is engaged with the surface of the connecting column 11 through the card slot, thereby preventing the main connector 1 and the auxiliary connector 2 from loosening and causing the optical fiber ceramic ferrule to separate.

[0031] Specifically, the two handles 603 are respectively provided with rubber rings 12

[0032] It can be understood that the cooperation between the rubber ring 12 and the optical fiber ceramic ferrule prevents moisture or dust from entering the main connector 1 and the auxiliary connector 2 and affecting the signal transmission of the optical fiber.

[0033] In the present invention, the connected optical fiber ceramic ferrule is inserted into the positioning hole 3 through the tapered hole 4, one end of the optical fiber ceramic ferrule in the main connector 1 stays in the positioning hole 3 of the main connector 1, and the optical fiber ceramic ferrule in the auxiliary connector 2 extends out of the step hole 9. The handle 603 is rotated to drive the threaded cylinder 601 to rotate, so that the top ring 602 pushes the clamping member 502 to slide in the slide groove 501, so that the clamping member 502 moves toward the tapered hole 4. Under the extrusion of the tapered hole 4, the clamping member 502 is deformed through the opening 503, and the optical fiber ceramic ferrule is clamped and fixed. In the above manner, the two optical fiber ceramic ferrules are respectively inserted into the main connector 1 and the auxiliary connector 2, and then the auxiliary connector 2 is inserted into the connecting ring 7. At the same time, the optical fiber ceramic ferrule in the auxiliary connector 2 is inserted through the guide bucket 8. The connecting rod 10 is inserted into the positioning hole 3 in the main connector 1 to dock the two optical fiber ceramic ferrules. The connecting rod 10 is then rotated to engage the surface of the connecting column 11 to prevent the main connector 1 and the auxiliary connector 2 from loosening and causing the two optical fiber ceramic ferrules to separate. The rubber ring 12 cooperates with the protective surface to prevent moisture or dust from entering the main connector 1 and the auxiliary connector 2 and affecting the signal transmission of the optical fiber. When the optical fiber ceramic ferrules need to be separated, the connecting rod 10 is separated from the connecting column 11, and the auxiliary connector 2 is pulled out of the connecting ring 7. The handle 603 is rotated to move the threaded barrel 601 outward, releasing the pressure on the clamping member 502. The clamping member 502 slides back to its original position due to the toughness of its own material, releasing the clamping of the optical fiber ceramic ferrule. The optical fiber ceramic ferrule is pulled out and the connector can be recycled.
