Description

TECHNICAL FIELD

[0002] Optical fiber communication technology has become one of the main pillars of modern communication and plays an important role in modern telecommunications networks. As a new technology, its rapid development and wide application in recent years are rare in the history of communication and are an important symbol of the world's new technology revolution and the main transmission tool of various information in the future information society.

[0003] The connection between optical fibers and the connection between optical fibers and devices are basically achieved through connectors. The connection between optical fibers and devices is generally achieved by setting a plug-in interface on the device and a plug-in head at the end of the optical fiber. The plug-in head is inserted into the plug-in interface to achieve the connection between the optical fiber and the device. The connection structure formed by the plug-in interface and the plug-in head has poor anti-disconnection performance. The plug-in interface and the plug-in head are both constructed with a plastic material clamping part that uses material deformation for elastic clamping and fixing. When the optical fiber cable is accidentally collided and pulled, the elastic clamping part is easily broken, which makes it unable to effectively clamp, causing the optical fiber plug-in head to loosen with the device plug-in interface, and in severe cases, causing separation, thereby affecting the connection and transmission of the optical fiber and affecting the normal operation of the device. At the same time, the elastic clamping is achieved by the deformation of the material itself, and the elastic deformation is easily lost after frequent plugging and unplugging, resulting in ineffective and stable connection. Therefore, the present application provides an optical fiber connector connecting structure. SUMMARY

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0030] As Figures 1-8 ​​As shown, the optical fiber connector connecting structure provided by one embodiment of the application comprises: a mounting frame 1 used for connecting with a device, wherein the mounting frame 1 surrounds a plug interface on the device when connected, one side of the mounting frame 1 is provided with a frame body 2, and opposite sides of the inner wall of the free end of the frame body 2 are both provided with sliding grooves 3; two plug plates 4 are slidingly inserted into the two sliding grooves 3, and the two plug plates 4 can block the frame body 2 after being slidingly buckled, opposite sides of the two plug plates 4 are both provided with a plurality of arc-shaped grooves 5, and corresponding two arc-shaped grooves 5 can surround to form a wire slot for optical fiber cables to pass through.When the plug of the optical fiber is plugged into the plug port of the device, the two insertion plates 4 are buckled to the frame 2, the plug is located in the frame 2, the optical fiber is movably penetrated through the wire slot formed by the two arc-shaped grooves 5, preferably, the diameter of the wire slot formed by the two arc-shaped grooves 5 is slightly larger than the diameter of the optical fiber, but smaller than the diameter of the plug, when the two insertion plates 4 are buckled, the end of the plug away from the plug port is in contact with the insertion plate 4, the sleeve 6 is movably sleeved on the frame 2, the outer surface of the sleeve 6 is arrayed with a plurality of anti-skid teeth, the anti-skid teeth are provided to increase the friction between the fingers and the sleeve 6, so that the sleeve 6 is more convenient to move, the opposite two sides of the frame 2 are both penetrated to form a through slot 7, the two insertion plates 4 are both provided with a support plate 8, the two support plates 8 are both penetrated to form an inclined slot 9, the opposite sides of the inner wall of the sleeve 6 are both provided with a shaft 10, the two shafts 10 are movably penetrated through the two through slots 7 and are movably inserted into the two inclined slots 9, the shaft 10 and the inner wall of the through slot 7 are connected with a limiting spring 11, preferably, when the two insertion plates 4 are buckled to seal the frame 2, the two shafts 10 are located in the end of the two inclined slots 9 with high inclination, when the device needs to be connected with the optical fiber, the sleeve 6 is moved upward along the frame 2, at this time, the shaft 10 is moved along the inclined slot 9, because the inclined slot 9 is inclined, and the shaft 10 moves vertically, therefore, when the sleeve 6 moves downward, the shaft 10 moves along the inclined slot 9, under the action of the inclined thrust, the insertion plate 4 moves horizontally along the sliding groove 3, because the two support plates 8 are respectively arranged on the two insertion plates 4, and the two inclined slots 9 are opposite in inclination, therefore, when the sleeve 6 moves, the shaft 10 will press the limiting spring 11, under the contact of the two shafts 10 and the two inclined slots 9, the two insertion plates 4 move away synchronously and reversely, so that the two insertion plates 4 unseal the frame 2, at this time, the plug of the optical fiber can be connected with the plug port of the device, so as to realize the connection between the optical fiber and the device, when the optical fiber is connected with the device, the sleeve 6 is loosened, under the elastic contact of the limiting spring 11, the sleeve 6 moves upward to reset, so that the two shafts 10 move along the two inclined slots 9 to reset, so as to drive the two insertion plates 4 to move close, so as to seal the frame 2 again, the two insertion plates 4 limit the plug of the optical fiber, because the sliding direction of the insertion plate 4 is perpendicular to the insertion direction of the plug of the optical fiber, and the buckling and locking are realized by the elastic contact of the limiting spring 11, therefore, when the optical fiber is accidentally touched or pulled, the two insertion plates 4 bear stress, and the plug of the optical fiber and the plug port of the device do not bear stress, so that the plug is not easy to loosen and separate, so as to ensure the stability of the connection between the optical fiber and the device, ensure that the device is not easily disturbed by the pulling of the optical fiber, and ensure the normal operation of the device.

[0031] As Figure 6As shown in the drawings, in some embodiments, the inner wall of the slot 7 is provided with a vertical rod 12 on the opposite side, the shaft rod 10 is slidably sleeved on the vertical rod 12, and the limiting spring 11 is movably sleeved on the vertical rod 12. By providing the vertical rod 12, the shaft rod 10 can be limited to move vertically, and the limiting spring 11 can be guided, so that the limiting spring 11 can only be elastically compressed and deformed along the axis of the vertical rod 12, and cannot be bent in a non-axis direction. That is, the elastic force of the limiting spring 11 can be maximized, and the stability of the elastic force of the limiting spring 11 is improved, and the stability of the connection between the optical fiber and the equipment is improved.

[0032] As shown in the drawings, Figure 6 and Figure 8 As shown in the drawings, in some embodiments, the vertical slot 13 is provided on the support plate 8 and communicates with the inclined slot 9. Preferably, the vertical slot 13 communicates with one end of the inclined slot 9 with high inclination. The opposite sides of the two plug plates 4 are respectively lapped with the opposite sides of the inner wall of the sleeve shell 6. When the two plug plates 4 are lapped with each other, the shaft rod 10 is located in one end of the inclined slot 9 with high inclination. Since the vertical slot 13 communicates with the inclined slot 9, and the sleeve shell 6 can move upwardly by a distance under the resistance of the elastic force of the limiting spring 11, the shaft rod 10 moves upwardly in the vertical direction from one end of the inclined slot 9 with high inclination, and then transitions from the inclined slot 9 to the vertical slot 13. At this time, the opposite sides of the two plug plates 4 are respectively lapped with the opposite sides of the inner wall of the sleeve shell 6, so as to limit the movement of the two plug plates 4, so that the two plug plates 4 can effectively limit and fix the plug of the optical fiber. Even if the optical fiber is subjected to an oblique pulling force, the plug plate 4 will not move, thereby improving the stability of the connection between the optical fiber and the equipment. When it is necessary to open the limiting blockage of the plug plate 4, the sleeve shell 6 is slid downwardly, and after the sleeve shell 6 moves vertically by a distance, the shaft rod 10 slides in the vertical slot 13 and then transitions to the inclined slot 9. After the sleeve shell 6 releases the limiting of the plug plate 4, the plug plate 4 can slide horizontally.

[0033] As shown in the drawings, Figure 8 In some embodiments, the shaft bearing 14 is fixedly arranged on the shaft rod 10 and is rollingly inserted into the inclined slot 9. Since the shaft rod 10 can only move vertically under the limitation of the slot 7 and the vertical rod 12, and the inclined slot 9 is inclinedly arranged, the shaft rod 10 will be subjected to an oblique stress when sliding in the inclined slot 9, resulting in a certain frictional resistance when the shaft rod 10 slides in the inclined slot 9. By arranging the shaft bearing 14 on the shaft rod 10 and rollingly lapping the shaft bearing 14 with the inclined slot 9, the sliding frictional resistance of the shaft rod 10 in the inclined slot 9 is reduced, so that the shaft rod 10 slides more smoothly. Not only does this make the plug plate 4 block or unblock smoothly, but also makes the sleeve shell 6 slide smoothly, thereby improving the practicability.

[0034] As shown in the drawings, Figure 1As shown in the drawings, in some embodiments, the two plug plates 4 are provided with a plurality of blocking pieces 15, and the plurality of blocking pieces 15 are one-to-one corresponding to the plurality of wire slots. When no optical fiber cable is inserted into the wire slot, the blocking piece 15 blocks the wire slot. Generally, a plurality of plug-in interfaces are provided on the equipment for connecting multiple optical fiber cables for network transmission tapping. However, the plug-in interfaces are not necessarily all plugged in. By providing the blocking piece 15, the blocking piece 15 blocks the wire slot without plugging in the optical fiber, so as to avoid the dust and impurities in the outside air from accumulating in the plug-in interface, thereby affecting the cleanliness of the plug-in interface, so as to ensure the stability of the subsequent connection and transmission of the plugged-in optical fiber, and to prevent interference, thereby improving the practicability.

[0035] As shown in the drawings, Figure 3 , Figure 4 and Figure 5 As shown in the drawings, in some embodiments, the blocking piece 15 comprises: two sealing plates 1501, preferably made of foam or rubber material, the opposite sides of the two plug plates 4 are provided with grooves 1502 communicating with the arc-shaped grooves 5, and the two sealing plates 1501 are movably inserted into the two grooves 1502, respectively. The sealing plate 1501 is connected with the inner wall of the groove 1502 through the abutting spring 1503. Preferably, under the condition that no external force is applied to the sealing plate 1501, the sealing plate 1501 partially protrudes from the groove 1502 under the elastic resistance of the abutting spring 1503. When the two plug plates 4 are slidably buckled, the two sealing plates 1501 abut each other to block the wire slot formed by the buckling of the two arc-shaped grooves 5, and the wire hole is blocked to prevent dust. When the two plug plates 4 are slidably buckled, the two sealing plates 1501 abut the optical fiber wire, and under the action of the counter-resisting force, the two sealing plates 1501 will be slidably contracted into the two grooves 1502, respectively, without affecting the normal passing of the optical fiber wire. At the same time, the elastic resistance of the abutting spring 1503 and the deformable property of the sealing plate 1501 itself can tightly abut the optical fiber to reduce the gap and improve the dustproof effect.

[0036] As shown in the drawings, Figure 4 and Figure 7 As shown in the drawings, in some embodiments, one side of the frame 2 is provided with a plug hole 16, and one side of the sleeve 6 is movably provided with a plug rod 17. The plug rod 17 is plugged and matched with the plug hole 16. When connecting the optical fiber wire, since multiple optical fiber wires need to be plugged, when the two plug plates 4 are opened and closed by sliding the sleeve 6 downward, the plug rod 17 can be movably inserted into the plug hole 16, the sleeve 6 and the frame 2 are temporarily fixed, and the two plug plates 4 after being opened and closed are temporarily fixed, so as to better plug the optical fiber wire. When the optical fiber is completely connected, the plug rod 17 is pulled out of the plug hole 16, the temporary fixing of the sleeve 6 and the frame 2 is released, and the sleeve 6 is reset under the elastic resistance of the limiting spring 11, so that the plug plate 4 limits and fixes the optical fiber, thereby improving the practicability.

[0037] like Figure 7 As shown, in some embodiments, a slot 18 is provided on one inner wall of the casing 6, and the insertion rod 17 moves through the slot 18. A limiting plate 19 is fixed on the insertion rod 17 and slidably inserted into the slot 18. The opening of the slot 18 and the setting of the limiting plate 19 form a limiting structure, preventing the insertion rod 17 from detaching from the casing 6, thus preventing loss. A return spring 20 is installed between the limiting plate 19 and the inner wall of the slot 18, sleeved on the insertion rod 17. When the sleeve 6 is located in the upper half of the frame 2 and the two insert plates 4 are fastened, the end of the insert rod 17 overlaps with the surface of the frame 2. At this time, the return spring 20 is in a compressed state. When the sleeve 6 slides down and the insert rod 17 is aligned with the insertion hole 16, the insert rod 17 is movably inserted into the insertion hole 16 under the elastic force of the return spring 20, thereby automatically fixing the sleeve 6 to the frame 2. The insert rod 17 is only manually pulled when the frame 2 and the sleeve 6 are released, thus improving convenience.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
