Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connectors, in particular to a tension-resistant optical fiber connector. Background Art

[0002] In the field of optical fiber transmission, optical fiber connectors (such as SC connectors) are common products. They are detachable devices that connect optical fibers to each other. They can connect the two end faces of optical fibers so that the optical signal can be continuous and form an optical path. When optical fibers are arranged in a normal state, the two optical fibers at the optical fiber connector may be forced to separate due to internal stress, tension and other factors, which may cause certain interference or blockage to the optical path. Utility Model Content

[0003] The utility model provides a tensile-resistant optical fiber connector, which can overcome certain defects of the prior art.

[0009] Preferably, a second compression spring is provided in the opening groove, and the tail end of the optical fiber connector abuts against the second compression spring.

[0017] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0018] Example 1

[0019] See Figure 1-5 The present embodiment provides a tensile-resistant optical fiber connector, which includes a connector body 100, the connector body 100 includes a connector sleeve 110 arranged in pairs, an opening groove 410 is provided on one side of the connector sleeve 110, a through hole 210 is provided on the bottom wall of the opening groove 410, the head end of the optical fiber connector is installed in the opening groove 410, and the tail end of the optical fiber connector extends out of the through hole 210. A tensile-resistant mechanism is provided on the outer wall of the connector sleeve 110, and the tensile-resistant mechanism is used to provide a buffer when the optical fiber is subjected to tension.

[0020] Specifically, when workers connect two optical fibers, they can use an SC connector, for example, and place the head end of the SC connector in the open groove 410, with the tail end of the SC connector extending out of the through hole 210. The tensile mechanism on the outer wall of the connector box 110 can act on the outer wall of the optical fiber. When the optical fiber is subjected to tension, the tensile mechanism can provide a buffer to prevent the optical fiber from being forced to separate from the SC connector due to "rigidity", thereby better ensuring the normal optical path.

[0021] Among them, the tensile mechanism includes a long strip 220 arranged on the side of the connector box 110 away from the opening groove 410, and the length direction of the long strip 220 is arranged along the length direction of the connector box 110. A partition 230 is provided at the end of the long strip 220 away from the connector box 110, and a limiting hole 430 is provided at the partition 230. A movable rod 250 is movably provided at the limiting hole 430. A baffle 240 is provided at the end of the movable rod 250 close to the connector box 110. A first compression spring 260 is sleeved on the outer wall of the movable rod 250 and arranged between the partition 230 and the baffle 240. A pull rod 270 is obliquely provided at the other end of the movable rod 250, and a clamp 280 is provided at the end of the pull rod 270. The axial direction of the clamp 280 is coaxially arranged with the axial direction of the through hole 210, and the clamp 280 is used to clamp the outer wall of the optical fiber.

[0022] Specifically, the optical fiber needs to maintain sufficient travel of the first compression spring 260 when it is at the maximum compression stroke. When the optical fiber is subjected to tension, the first compression spring 260 can better reduce the tension to achieve a buffering effect. During this process, the movable rod 250 moves at the limiting hole 430, and the clamp 280 can be better clamped on the outer wall of the optical fiber, driving the movable rod 250 to move following the displacement of the corresponding section of the optical fiber.

[0023] See Figure 5 A rubber pad 510 is provided on the inner wall of the clamp 280 .

[0024] Specifically, the rubber pad 510 can better protect the outer wall of the optical fiber and better achieve the matching between the clamp 280 and the outer wall of the optical fiber.

[0025] It is understandable that the longitudinal sections of the limiting hole 430 and the movable rod 250 are both polygonal.

[0026] Specifically, the limiting hole 430 can better limit the movable rod 250 to prevent the movable rod 250 from rotating and causing damage to the optical fiber due to the rotation.

[0027] See Figure 4 A second compression spring 420 is disposed in the opening groove 410 , and the tail end of the optical fiber connector rests against the second compression spring 420 .

[0028] Specifically, when the optical fiber is subjected to tension, the second compression spring 420 can effectively reduce the tension and provide a buffering effect for the SC connector.

[0029] The opening slot 410 is provided with a notch 112 at the opening.

[0030] Specifically, the notch 112 facilitates workers to install the SC connector in the connector box 110 .

[0031] See Figure 1The joint box 110 is located at the outer wall edge of the opening groove 410 and is formed with a flange mounting plate 111 . The joint boxes 110 arranged in pairs are connected by bolts through the corresponding flange mounting plates 111 .

[0032] Specifically, after the workers connect the SC connectors of the two optical fibers, they can fix the matching connector box 110 by bolts, which is relatively convenient.

[0033] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0034] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the protection scope of the present invention.
