DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0047] See also Figure 1-Figure 8 The embodiment of the present invention provides a tensile-resistant optical fiber active connector, comprising an active connector body 1, one end of which is provided with a plug connector 2, and further comprising:

[0048] A polygonal knob 6, which is detachably connected to the other end of the movable connector body 1;

[0049] and a tensile protection mechanism, which is connected to the movable connector body 1 and the polygonal knob 6 respectively, wherein the tensile protection mechanism includes an optical fiber cable 13 and a winding tensile component;

[0050] The winding anti-tension component is fixedly connected to the polygonal knob 6 and is detachably connected to the movable connector body 1. The optical fiber cable 13 passes through the polygonal knob 6 and is wound around the winding anti-tension component, and one end of the optical fiber cable 13 is also electrically connected to the plug connector 2.

[0051] See also Figure 1-Figure 8 , further comprising: a locking thread head 15, both ends of which are respectively connected to the polygonal knob 6 and the winding tension-resistant component, and are threadedly connected to the movable connector body 1;

[0052] and a connecting portion 4 , wherein the connecting portion 4 is located inside the plug connector 2 .

[0053] During the use of the optical fiber, first, the polygonal knob 6 can be removed from the movable connector body 1 (wherein, the end of the movable connector body 1 is provided with an internal thread, so that the locking thread head 15 can be threadedly connected to the end of the movable connector body 1, which will not be described in detail here), and one end of the optical fiber cable 13 is passed through the polygonal knob 6 and then wrapped around the winding and tensile assembly, and finally electrically connected to the connecting part 4 on the plug connector 2 (the connecting part 4 can adopt the existing technology), and then, the polygonal knob 6 and the winding and tensile assembly are installed on the movable connector body 1. At this time, the winding and tensile assembly is located in the movable connector body 1, and the optical fiber cable 13 is in contact with the inner wall surface of the movable connector body 1. When the optical fiber cable 13 is tightened by external force, the position where the end of the optical fiber cable 13 is electrically connected to the connecting part 4 will not be loosened due to the tension under the obstruction of the winding and tensile assembly. The operation is simple, and the loosening of the contact position due to tension can be avoided, thereby avoiding the problem of optical fiber sliding, signal attenuation or even interruption, which is conducive to ensuring the normal transmission of optical fiber signals and provides convenience for users.

[0054] In one embodiment of the present invention, see Figure 1-Figure 8 , the winding tensile component comprises:

[0055] A tensile protection column 16, one end of which is fixedly connected to the polygonal knob 6;

[0056] A through threading hole 22, wherein the through threading hole 22 passes through the polygonal knob 6 and the tensile protection column 16;

[0057] and a spiral tensile groove 18, wherein the spiral tensile groove 18 is provided on the tensile protection column 16, and a wire inlet 20 and a wire outlet 21 are provided at both ends of the spiral tensile groove 18, wherein the wire inlet 20 and the wire outlet 21 are both provided on the tensile protection column 16 and are both connected to the through threading hole 22;

[0058] The optical fiber cable 13 is inserted into the through-wire hole 22, passes through the wire outlet 21 and is then wound in the spiral tensile groove 18, and then passes through the wire inlet 20 and is inserted into the through-wire hole 22. Finally, the end of the through-wire hole 22 is electrically connected to the plug connector 2.

[0059] It also includes: an anti-skid protrusion 19 , and the number of the anti-skid protrusions 19 is multiple, and the multiple anti-skid protrusions 19 are evenly distributed in the spiral tensile groove 18 .

[0060] It also includes: an anti-skid covering surface 14, which covers the optical fiber cable 13 and contacts the anti-skid protrusion 19, wherein the anti-skid covering surface 14 is made of rubber and adhered to the surface of the optical fiber cable 13 by glue.

[0061] During the installation of the optical fiber cable 13, the polygonal knob 6 and the tensile protection column 16 can be removed from the movable connector body 1, and one end of the optical fiber cable 13 is inserted into the through-wire hole 22, and after extending out of the through-wire hole 22 through the wire outlet 21, it is wound in the spiral tensile groove 18, and then inserted into the through-wire hole 22 again through the wire inlet 20, and finally electrically connected to the connecting portion 4 on the plug connector 2. After the optical fiber cable 13 is subjected to external force, the anti-slip protrusion 19 set in the spiral tensile groove 18 and the anti-slip coating surface coated on the optical fiber cable 13 are 14 (wherein the anti-skid coating 14 is relatively thin and is adhered to the surface of the optical fiber cable 13 with glue to prevent relative sliding between the optical fiber cable 13 and the anti-skid coating 14 when the optical fiber cable 13 is subjected to external force. In addition, the anti-skid protrusion 19 can adopt a V-shaped structure), the anti-skid coating 14 and the anti-skid protrusion 19 cooperate to prevent the optical fiber cable 13 from sliding in the spiral tensile groove 18, thereby achieving the purpose of tensile resistance and preventing the connection point between the end of the optical fiber cable 13 and the connecting part 4 from loosening due to force, which provides convenience for users.

[0062] In one embodiment of the present invention, see Figure 1-Figure 8 , further comprising: a guide hose 8, the guide hose 8 being fixedly mounted on the polygonal knob 6 and being connected to the through threading hole 22;

[0063] An L-shaped connecting rod 9, wherein the number of the L-shaped connecting rods 9 is multiple, and the multiple L-shaped connecting rods 9 are evenly distributed on the guide hose 8;

[0064] An annular detection portion 10, wherein the annular detection portion 10 is fixedly mounted on the polygonal knob 6, and the annular detection portion 10 is fixedly connected to the other end of the L-shaped connecting rod 9;

[0065] And an anti-tensile warning portion 7 , wherein the anti-tensile warning portion 7 is located on the polygonal knob 6 and is electrically connected to the annular detection portion 10 .

[0066] It also includes: a surplus storage bin 28 , which is located on one end of the tensile protection column 16 away from the polygonal knob 6 .

[0067] It also includes: a mobile detection head 17, which is detachably installed in the surplus storage bin 28;

[0068] and an elastic groove plate 23 , one end of which is fixedly connected to the mobile detection head 17 , and the optical fiber cable 13 is also inserted into the elastic groove plate 23 .

[0069] During the use of the optical fiber, the optical fiber cable 13 is located in the guide hose 8. When the optical fiber cable 13 is subjected to an inclined tensile force, the optical fiber cable 13 will generate a thrust on the guide hose 8, thereby deforming the guide hose 8. During the bending of the guide hose 8, a thrust is generated on the L-shaped connecting rod 9 in the specified direction, so that a certain position of the annular detection part 10 detects the force. At this time, the sensor provided on the annular detection part 10 will control the start of the tensile warning part 7, wherein the tensile warning part 7 can be in the form of a flashing light or a buzzer. When the tensile warning part 7 starts working, it means that the optical fiber cable 13 may be subjected to an external force, which can play a part of the early warning role. In addition, during the installation of the optical fiber cable 13, a part of the optical fiber cable 13 can be reserved in the surplus accommodation bin 28. Even if the optical fiber cable 13 is pulled and relatively slides with the spiral tensile groove 18 for a short distance, the small section of the optical fiber cable 13 reserved in the surplus accommodation bin 28 can extend out of the through-hole 22 (even if the entire installed optical fiber cable 13, and it is not in a tight state between the contact point position), and will not affect the contact point position, thereby further ensuring the tensile strength. In addition, when all the optical fiber cables 13 reserved in the surplus storage bin 28 are used up, the optical fiber cables 13 will slide in the elastic groove plate 23 (wherein, under normal use, the optical fiber cables 13 will be stuck in the elastic groove plate 23, and the elastic groove plate 23 will be deformed, thereby squeezing the surface of the optical fiber cables 13). On the one hand, the elastic groove plate 23 can have a certain hindering effect on the movement of the optical fiber cables 13, thereby ensuring the tensile strength of the optical fiber cables 13. On the other hand, when the optical fiber cables 13 slide in the elastic groove plate 23, the elastic groove plate 23 will be deformed under the action of friction. Wherein, a sensor is also provided on the elastic groove plate 23. When the elastic groove plate 23 is deformed, the sensor will control the tensile warning part 7 to start, so as to ensure that the optical fiber cables 13 can play a warning role even when they are not subjected to the inclined pulling force. No more details will be given here.

[0070] In one embodiment of the present invention, see Figure 1-Figure 8 , further comprising: a rotation locking portion 3, wherein the rotation locking portion 3 is rotatably mounted on the plug connector 2;

[0071] A threaded tightening portion 12, wherein the threaded tightening portion 12 is located inside the rotation locking portion 3, and the threaded tightening portion 12 is also threadedly connected to a connector on another optical fiber cable 13;

[0072] And a limit control component, which is located on the plug connector 2 and is detachably connected to a connector on another optical fiber cable 13, and the limit control component is also electrically connected to a pressure sensor provided in the spiral tensile groove 18.

[0073] The limit control component comprises:

[0074] The inflation port 5 and the discharge control port 11 are both fixedly connected to the plug connector 2, wherein the solenoid valve disposed on the discharge control port 11 is electrically connected to the pressure sensor disposed in the spiral tensile groove 18;

[0075] An annular groove 24, wherein the annular groove 24 is provided in the plug connector 2, and an arc-shaped adjusting member 27 is fixedly installed in the annular groove 24, and the arc-shaped adjusting member 27 is respectively connected to the inflation port 5 and the discharge control port 11;

[0076] Arc-shaped pull rods 26, the number of the arc-shaped pull rods 26 is two, the two arc-shaped pull rods 26 are respectively inserted at the two ends of the arc-shaped adjusting member 27, and are both slidably connected to the arc-shaped adjusting member 27;

[0077] And an elastic anti-slip belt 25 , the two ends of which are respectively fixedly connected to the two arc-shaped pull rods 26 , and the elastic anti-slip belt 25 is also detachably connected to a connector on another optical fiber cable 13 .

[0078] When two optical fibers are connected, the connector on the other optical fiber cable 13 can be inserted into the rotary locking part 3 and threadedly connected with the threaded tightening part 12. The rotary locking part 3 can be rotated on the plug connector 2 by human power, and the connector on the other optical fiber cable 13 can be gradually screwed into the rotary locking part 3 and finally reach the position of the annular groove 24, wherein the inner diameter of the annular groove 24 is larger than the inner diameter of the rotary locking part 3. Then, after the connector end on the other optical fiber cable 13 enters the annular groove 24, it is in a suspended state. At this time, high-pressure gas is installed in the arc-shaped adjustment member 27, wherein the arc-shaped adjustment member 27 can be in the form of an arc-shaped chamber and is provided with a spring, and the spring is connected to the arc-shaped pull rod 26. When the arc-shaped adjustment member 27 is in a high-pressure state, the spring is in a compressed state. At this time, most of the length of the arc-shaped pull rod 26 extends to the outside of the arc-shaped adjustment member 27 and is placed in the annular groove 24 (such as Figure 8As shown), the elastic anti-slip belt 25 is also in a relaxed state, wherein the elastic anti-slip belt 25 can be made of rubber material, similar to the form of a balloon, and similar to the structure of the anti-slip covering surface 14. When the elastic anti-slip belt 25 is in a relaxed state, the elastic anti-slip belt 25 does not contact the end of the connector in a suspended state. When the elastic groove plate 23 is deformed by tension, it means that the surplus in the surplus accommodating bin 28 has been pulled out. At this time, the external pulling force may be large. In order to further ensure the tensile strength of the overall equipment (the strength of the connection between connectors), the elastic groove plate 23 will control the solenoid valve on the discharge control port 11 to open. At this time, the high-pressure gas in the arc-shaped adjusting member 27 will flow out, and the arc-shaped pull rod 26 will slide into the arc-shaped adjusting member 27 under the elastic action of the spring. At this time, the elastic anti-slip belt 25 will be stretched and tightly wrapped around the end of the connector on the other optical fiber cable 13 (the arc-shaped adjusting member 27 The arc length is less than half of the circumference of the annular groove 24), and since the connector end on the other optical fiber cable 13 is a threaded structure, the elastic anti-slip band 25 will be tightly attached to the thread, which can increase the stability of the connection between the threaded tightening part 12 and the connector on the other optical fiber cable 13 (it can hinder the lateral displacement between the threaded tightening part 12 and the connector), and when it is necessary to disassemble the threaded tightening part 12 and the connector, it is only necessary to inflate the inflation port 5 through an external air source to restore the arc adjustment member 27 to a high pressure state again. At this time, the arc pull rod 26 slides toward the outside of the arc adjustment member 27 again to separate the elastic anti-slip band 25 from the connector, so that the two can be disassembled. Among them, in order to consider the cost and installation difficulty, in the use scenario where the stability between the threaded tightening part 12 and the connector can always be guaranteed, the arc adjustment member 27 and other structures can be not set, and they can be selected according to actual needs. No further details will be given here.

[0079] It should be noted that in the present invention, unless otherwise clearly specified and limited, the terms "slide", "rotate", "fix", "have" and the like should be understood in a broad sense, for example, it can be a welding connection, a bolt connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0080] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
