Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber connectors, in particular to a fixed connector for optical fiber communication. Background Art

[0002] Fiber optic communication is a communication method that uses light waves to transmit information in optical fibers. The structure of current fiber optic communication connectors is generally complex. Especially in the process of connecting with other devices, specific tools are required to fix the fiber optic communication connectors to other objects or connectors, which affects the installation progress of construction personnel and makes disassembly during maintenance troublesome, making it inconvenient for construction teams.

[0003] To solve the above problems, Chinese patent announcement No. CN210605084U discloses a fiber optic communication cable connector with stable connection, including a fiber optic cable, a joint connection shell is fixedly installed on the left side of the fiber optic cable, a protective anti-folding ring corresponding to the fiber optic cable is fixedly installed on the right side of the joint connection shell, a soft rubber ring corresponding to the fiber optic cable is fixedly installed on the inner wall of the protective anti-folding ring, a connection gasket is fixedly installed on the left side of the joint connection shell, an optical fiber inner cable extending to the inside of the joint connection shell is fixedly installed on the left side of the optical fiber cable, two support seats corresponding to the optical fiber inner cables are fixedly installed on the inner wall of the joint connection shell, a load-bearing limit ring corresponding to the optical fiber inner cable is fixedly installed on the top of the bottom support seat, a transmission joint connected to the optical fiber inner cable is fixedly installed on the left side of the joint connection shell, a threaded connection hole is opened on the top of the connection gasket, a threaded connection nail penetrating the connection gasket is movably installed inside the threaded connection hole, a limiting connection ring is fixedly installed on the top of the threaded connection nail, and stable gaskets are fixedly installed on both sides of the support seat.

[0004] The above scheme solves the problems of complex structure and inconvenient disassembly existing in the prior art, but the scheme uses threaded connecting nails to connect the connector shell. In actual use, the operation time during the connection process is relatively long, and the threaded connecting nails are prone to dislocation during the fixing process, which affects the connection effect. Therefore, it is necessary to propose a fixed connector for optical fiber communication, which can solve the problem of using threaded connecting nails to connect the connector shell in the prior art to a certain extent. In actual use, the operation time during the connection process is relatively long, and the threaded connecting nails are prone to dislocation during the fixing process, which affects the connection effect. Utility Model Content

[0005] The purpose of the utility model is to provide a fixed connector for optical fiber communication, which is used to solve the problem that the existing technology uses threaded connection nails to connect the connector connection shell, and in actual use, the operation time during the connection process is relatively long, and the threaded connection nails may be misplaced during the fixing process, thus affecting the connection effect.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a fixed connector for optical fiber communication, including a female connector and a male connector, the female connector and the male connector are detachably connected by threads, the outer side wall of the female connector is provided with a fixing device, the fixing device includes a nut and a plurality of clamps, the nut and the outer side wall of the connector are detachably connected by threads, the clamps are hinged to the side wall of the female connector, and the other end of the clamp is detachably connected to the male connector.

[0007] After adopting the above scheme, the following principles and beneficial effects are achieved: when using the present device, the female connector and the male connector are first connected to each other, and then the clamping jaw is rotated to a certain angle through the nut so that the end of the clamping jaw away from the female connector contacts the outer wall of the male connector, and the nut is continued to be rotated so that the end of the clamping jaw away from the female connector is fixed to the outer wall of the male connector, thereby completing the fixation of the male connector and the present device. When it is necessary to release the connection between the present device and the male connector, the nut is rotated in the opposite direction and then the female connector is rotated in the opposite direction to complete the release of the fixation of the male connector. Through the setting of the fixing device, the present device can simply and conveniently complete the fixation of the connectors, which to a certain extent solves the problem of using threaded connecting nails to connect the joint connection shells in the prior art, and in actual use, the operation time during the connection process is relatively long, and the threaded connecting nails are easily dislocated during the fixing process, thereby affecting the connection effect.

[0008] Furthermore, one end of the clamping jaw away from the female connector is fixedly connected with a rubber pad.

[0009] Beneficial effect: When the clamping jaw contacts the outer wall of the male connector during use of the device, the rubber pad can increase the friction between the clamping jaw and the outer wall of the male connector, so that the clamping jaw is not easy to shift during use of the device, thereby enhancing the fixing effect of the device. At the same time, the rubber pad can also reduce the wear of the clamping jaw on the outer wall of the male connector to a certain extent, thereby extending the service life of the male connector.

[0010] Furthermore, a torsion spring is sleeved at the hinge of the clamping jaw and the female connector, one end of the torsion spring is fixedly connected to the side wall of the clamping jaw, and the other end of the torsion spring is fixedly connected to the female connector.

[0011] Beneficial effect: when the male connector needs to be released, the nut is rotated in the opposite direction, and the torsion spring can make the clamping claw quickly leave the outer wall of the male connector, thus shortening the operation time of the operator and improving the work efficiency of the operator.

[0012] Furthermore, one end of the inner side wall of the nut close to the clamping claw is arranged obliquely.

[0013] Beneficial effect: When using the device, when the rotating nut pushes the clamping jaw to fix the outer wall of the male connector, the inclined inner wall of the nut can reduce the pressure exerted by the nut on the clamping jaw, thereby making the clamping jaw less likely to be worn by the nut and extending the service life of the device.

[0014] Furthermore, a rubber ring is fixedly connected to the side wall of the nut close to the clamping jaw.

[0015] Beneficial effect: When the nut is rotated to push the clamp to rotate during use of the device, the rubber ring can increase the friction between the nut and the clamp, thereby reducing the probability of the nut loosening due to external vibration, while also reducing the wear of the nut on the clamp, thereby extending the service life of the device.

[0016] Furthermore, a plurality of protrusions are fixedly connected to the outer side wall of the nut.

[0017] Beneficial effect: When using the device, the protrusion can increase the friction between the outer wall of the nut and the operator's hand, making it less likely for the operator to slip when turning the nut.

[0018] Furthermore, the ends of the female connector and the male connector that are away from each other are both fixedly connected with spiral fixing bands.

[0019] Beneficial effect: During the use of the device, the spiral fixing belt can prevent the light from being easily broken at the position where it enters the female connector or the male connector, thereby affecting the use effect of the optical fiber.

[0020] Furthermore, one end of the female connector away from the spiral fixing belt is fixedly connected to a locking ring made of elastic material.

[0021] Beneficial effect: When the female connector is connected to the male connector during use, the anti-loosening ring made of elastic material can increase the friction between the female connector and the male connector, so that the male connector is not easily removed from the female connector due to external vibration during use.

[0025] Embodiment 1

[0026] The embodiment is basically as shown in the attached Figure 1 As shown:

[0027] A fixed connector for optical fiber communication includes a female connector 1 and a male connector 4. The female connector 1 is detachably connected to the male connector 4 through threads. The outer wall of the female connector 1 is provided with a fixing device, which includes a nut 3 and a plurality of clamping jaws 2. The nut 3 and the outer wall of the connector are detachably connected through threads. The clamping jaws 2 are hinged to the side wall of the female connector 1, and the other end of the clamping jaw 2 is detachably connected to the male connector 4 through a buckle.

[0028] The specific implementation process is as follows: when using this device, first connect the female connector 1 and the male connector 4 to each other, then rotate the nut 3 in the direction close to the clamping jaw 2. The nut 3 is close to the side wall of the clamping jaw 2 and pushes the clamping jaw 2 to rotate a certain angle, so that the end of the clamping jaw 2 away from the female connector 1 contacts the outer wall of the male connector 4, and the nut 3 is continued to be rotated so that the end of the clamping jaw 2 away from the female connector 1 is fixed to the outer wall of the male connector 4 by a snap, thereby completing the connection of the optical fibers at both ends. When it is necessary to release the connection between this device and the male connector 4, rotate the nut 3 in the reverse direction to release the fixation of the clamping jaw 2 to the male connector 4, open the clamping jaw 2, and then rotate the female connector 1 in the reverse direction to complete the release of the fixation of the male connector 4. Through the setting of the fixing device, this device can simply and conveniently complete the fixation between the connectors.

[0029] Embodiment 2

[0030] The difference from the above embodiment is that a rubber pad 21 is bonded to one end of the clamping jaw 2 away from the female connector 1 .

[0031] The specific implementation process is as follows: when the clamping jaw 2 contacts the outer wall of the male connector 4 during use of the device, the rubber pad 21 increases the contact area between the clamping jaw 2 and the outer wall of the male connector 4 through its own elastic deformation, thereby increasing the friction between the clamping jaw 2 and the outer wall of the male connector 4, so that during the use of the device, the clamping jaw 2 is not easy to shift, thereby enhancing the fixing effect of the device. At the same time, the rubber pad 21 can also reduce the wear of the clamping jaw 2 on the outer wall of the male connector 4 to a certain extent, thereby extending the service life of the male connector 4.

[0032] Embodiment 3

[0033] The difference from the above embodiment is that a torsion spring is sleeved at the hinge of the clamping jaw 2 and the female connector 1 , one end of the torsion spring is welded to the side wall of the clamping jaw 2 , and the other end of the torsion spring is welded to the female connector 1 .

[0034] The specific implementation process is as follows: when it is necessary to release the fixation of the male connector, the nut 3 is rotated in the opposite direction, and the torsion spring, under the action of its own elastic force, causes the clamping jaw 2 to quickly leave the outer wall of the male connector 4, thereby shortening the operator's operation time and improving the operator's work efficiency.

[0035] Embodiment 4

[0036] The difference from the above-mentioned embodiment is that the inner wall of the nut 3 at one end close to the clamping jaw 2 is arranged in an inclined manner in a truncated cone shape.

[0037] The specific implementation process is as follows: when using the device, when the rotating nut 3 pushes the clamping jaw 2 to fix the outer wall of the male connector 4, the inclined inner wall of the nut 3 can increase the contact area between the clamping jaw 2 and the nut 3, so that the pressure applied by the nut 3 on the clamping jaw 2 is reduced, so that the clamping jaw 2 is not easily worn by the nut 3, thereby extending the service life of the device.

[0038] Embodiment 5

[0039] The difference from the above embodiment is that a rubber ring 32 is bonded to the side wall of the nut 3 close to the clamping jaw 2 .

[0040] The specific implementation process is as follows: when using the device, the rotating nut 3 pushes the clamping jaw 2 to rotate, and the rubber ring 32 increases the contact area between the nut 3 and the clamping jaw 2 through its own elastic deformation, thereby increasing the friction between the nut 3 and the clamping jaw 2, thereby reducing the probability of the nut 3 loosening due to external vibration, and at the same time reducing the wear of the nut 3 on the clamping jaw 2, thereby extending the service life of the device.

[0041] Embodiment 6

[0042] The difference from the above embodiment is that a plurality of protrusions 31 are integrally formed on the outer side wall of the nut 3 .

[0043] The specific implementation process is as follows: when using the device, the protrusion 31 can increase the contact area between the nut 3 and the operator's hand, thereby increasing the friction between the outer wall of the nut 3 and the operator's hand, making it less likely for the operator to slip when turning the nut 3.

[0044] Embodiment 7

[0045] The difference from the above embodiment is that the ends of the female connector 1 and the male connector 4 that are away from each other are both bonded with spiral fixing bands 12 .

[0046] The specific implementation process is as follows: when using this device, the optical fiber is first passed through the axis of the spiral fixing belt 12, and then through the axis of the female connector 1 or the male connector 4. During the use of this device, the spiral fixing belt 12 can provide certain support to the optical fiber, so that the light is not easy to break at the position where it enters the female connector 1 or the male connector 4, affecting the use effect of the optical fiber.

[0047] Embodiment 8

[0048] The difference from the above-mentioned embodiment is that an anti-loosening ring 11 made of elastic material is bonded to one end of the female connector 1 away from the spiral fixing band 12 .

[0049] The specific implementation process is as follows: when the female connector 1 is connected to the male connector 4 when using the device, the anti-loosening ring 11 made of elastic material can increase the contact area between the male connector 4 and the female connector 1 through its own elastic deformation, thereby increasing the friction between the female connector 1 and the male connector 4, so that the male connector 4 is not easy to fall off from the female connector 1 due to external vibration during use.
