[0002] The jumper can provide bidirectional data transmission, realize bidirectional data transmission between two devices, and provide a reliable connection with strong anti - interference ability. According to the prior art, such as a kind of anti - fracture jumper described in the Chinese patent document CN207353550U, in the disclosed technical solution, through the setting of the spherical card on the card head piece cooperating with the spherical card cavity on the crystal head, when suffering an impact force, the card head piece can rotate around the spherical card; the spring body is limited by the rubber tube, and at the same time, the clamping effect can also be realized through the action of the spring body.

[0003] According to the disclosed technical solution, various jumpers in the prior art can only reinforce the end part to achieve the function of anti - fracture protection, but lack effective buffer protection for the main part of the wire. Especially for thinner optical fiber wires, the probability of the wire itself breaking is greater, and once impacted, it will cause the surface of the wire to break or the port position to become loose, thus affecting subsequent normal connection and transmission use. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an anti - fracture double - core jumper to solve the problems put forward in the above background technique. The utility model also provides anti - fracture protection treatment for the port and the main part of the wire, and can also provide connection and protection when the distance between the connection ports is far.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: an anti - fracture double - core jumper, including a double - core jumper body, the double - core jumper body includes a rubber sleeve, a plug connector, a fitting mechanism and a buffer member. Extension wires are connected to both ends of the rubber sleeve, plug connectors are installed at the ends of the extension wires, the fitting mechanism is attached to the side of the plug connector, wire cores are inserted into the rubber sleeve, slots are opened on the surface of the rubber sleeve, the surface of each fitting mechanism is connected to the end of the buffer member, and the buffer member is fixedly connected to the surface of the rubber sleeve.

[0006] Further, a rib is integrally formed on the surface of the plug connector, and a first connecting rope is connected to the rear end of the plug connector, and the other end of the first connecting rope is fixedly connected to the end of the rubber sleeve.

[0007] Further, two first connecting ropes are arranged around each extension wire, and the length of the first connecting rope is the same as the length of the extension wire, and the rubber sleeve is made of rubber material as a whole.

[0008] Furthermore, the bonding mechanism includes an extension strip and an inclined plate, a slot is provided at the bottom of the extension strip, an inclined plate is integrally formed on one side of the extension strip, and a bonding plate is integrally formed on the top of the inclined plate.

[0009] Furthermore, a first adhesive layer is coated on one side of the bonding plate, a second adhesive layer is coated on the inner wall of the card slot, the card slot is sleeved on the surface of the convex strip, and the top of the convex strip is bonded to the second adhesive layer as a whole.

[0010] Furthermore, the buffer component includes a buffer sleeve and a second connecting rope, a plug-in column is inserted into the interior of the slot, a pressure plate is provided on the top of the plug-in column, a connecting ring is provided on the top of the pressure plate and the extension strip, and the second connecting rope is combined and fixed with the connecting ring.

[0011] Furthermore, the surface of the plug-in column is provided with an anti-stripping feature, and the anti-stripping feature is embedded in the inner wall of the slot.

[0013] Beneficial effects of the utility model:

[0014] 1. The anti-breakage dual-core jumper is equipped with a fitting mechanism at both ends. After the jumper is plugged in, the fitting mechanism can provide an additional adhesive connection effect above the plug interface. With the help of the adhesive effect, the jumper will not easily detach from the plug hole when it is impacted later, thereby improving the stability of the connection.

[0015] 2. The anti-break dual-core jumper has a buffer installed on the surface of the jumper, and the length of the buffer is slightly smaller than the length of the wire body. Therefore, when the jumper is pulled, the force will first act on the buffer, and the buffer will first provide a tensile buffering effect to prevent the pulling from continuing to act on the wire, thereby reducing the probability of the wire being broken.

[0016] 3. The anti-break dual-core jumper is synchronously connected to the fitting mechanism at both ends of the buffer, and multiple connection points are arranged on the surface of the rubber sleeve. Therefore, after the jumper is pulled, the pulling force can be quickly and evenly applied to different positions of the wire and the fitting mechanisms at both ends, and the pulling force is evenly dispersed to avoid concentrated action at a fixed position, thereby improving the tensile strength.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: An anti - fracture double - core jumper, including a double - core jumper body, the double - core jumper body includes a rubber sleeve 1, a plug joint 2, a fitting mechanism 3 and a buffer 4. Extension wires 7 are connected to both ends of the rubber sleeve 1, and a plug joint 2 is installed at the end of the extension wire 7. The fitting mechanism 3 is mounted on the side of the plug joint 2. A wire core 6 is inserted through the inside of the rubber sleeve 1. Slots 5 are provided on the surface of the rubber sleeve 1. The surface of each fitting mechanism 3 is connected to the end of the buffer 4, and the buffer 4 is fixedly connected to the surface of the rubber sleeve 1. This anti - fracture double - core jumper belongs to an optical fiber cable and is used to connect optical fiber transmission devices at both ends.

[0024] When the present utility model is used, directly insert the plug joints 2 at both ends of the jumper into external optical fiber devices, then the bottom of the fitting mechanism 3 can be embedded and bonded with the rib 9 on the plug joint 2, and the top of the fitting mechanism 3 can be bonded around the connection port of the plug joint 2 to complete the installation. After being impacted subsequently, the anti - fracture protection effect can be achieved through the fitting mechanism 3, the rubber sleeve 1 and the buffer 4 on the surface of the rubber sleeve 1.

[0025] In this embodiment, a rib 9 is integrally formed on the surface of the plug connector 2. A first connecting rope 8 is connected to the rear end of the plug connector 2, and the other end of the first connecting rope 8 is fixedly connected to the end of the rubber sleeve 1. Two first connecting ropes 8 are arranged around each extension wire 7, and the length of the first connecting rope 8 is the same as that of the extension wire 7. The rubber sleeve 1 is made of rubber material as a whole. Specifically, two plug connectors 2 are provided at each end of the duplex jumper. Therefore, the two plug connectors 2 are respectively connected to the ports on the optical fiber device, and with the help of the independently provided extension wire 7, the plug connectors 2 can be flexibly adjusted according to the distance between the two plugging ports on the optical fiber device.

[0026] In this embodiment, the fitting mechanism 3 includes an extension strip 10 and an inclined plate 11. A card slot 14 is formed at the bottom of the extension strip 10. An inclined plate 11 is integrally formed on one side of the extension strip 10, and a fitting plate 12 is integrally formed on the top of the inclined plate 11. A first adhesive layer 13 is coated on one side of the fitting plate 12, and a second adhesive layer 24 is coated on the inner wall of the card slot 14. The card slot 14 is sleeved on the surface of the rib 9, and the top of the rib 9 is bonded to the second adhesive layer 24 as a whole. The fitting mechanism 3 is installed at both ends. After the jumper is plugged in, an additional adhesive connection effect can be provided above the plug-in port by means of the fitting mechanism 3. With the help of this adhesive effect, the jumper will not easily come off from the plug-in hole part when it is impacted subsequently, improving the connection stability.

[0027] Specifically, by connecting the bottom extension strip 10 to the rib 9 on the surface of the plug connector 2 after plugging, and connecting the rib 9 and the extension strip 10 as a whole with the help of the second adhesive layer 24, the two plug connectors 2 can be bound together at the same time. When any one of the plug connectors 2 is impacted and may become detached, the impact force can be evenly transmitted to the other plug connector 2 through the fitting mechanism 3, thereby dispersing the influence caused by the impact force. At the same time, an additional adhesive fixing effect is further provided by means of the first adhesive layer 13 on the top.

[0028] In this embodiment, the buffer member 4 includes a buffer sleeve 15 and a second connecting rope 19. An insertion column 22 is inserted into the interior of the slot 5. A pressing plate 20 is provided at the top of the insertion column 22. A connecting ring 21 is provided at the top of the pressing plate 20 and the extension strip 10. The second connecting rope 19 is fixedly combined with the connecting ring 21. Anti-detachment thorns 23 are provided on the surface of the insertion column 22, and the anti-detachment thorns 23 are embedded into the inner wall of the slot 5. Threading holes 17 are formed at both ends of the buffer sleeve 15, and inner convex rings 18 are integrally formed on the inner walls of the threading holes 17. The second connecting rope 19 is inserted into the interior of the buffer sleeve 15 from the threading holes 17. A spring 16 is installed in the buffer sleeve 15, and both ends of the spring 16 are fixedly connected to the two second connecting ropes 19 respectively. The buffer member 4 is installed on the surface of the jumper wire, and the length of the buffer member 4 is slightly shorter than the length of the wire body. Therefore, after the jumper wire is pulled, the force will first act on the buffer member 4, and the buffer member 4 is used to provide a stretching buffer effect first, so as to avoid the continuous action of the pulling force on the wire, thereby reducing the probability of the wire being broken.

[0029] Both ends of the buffer member 4 are synchronously connected to the fitting mechanism 3, and multiple connection points are provided on the surface of the rubber sleeve 1. Therefore, after the jumper wire is pulled, the pulling force can be quickly and evenly applied to different positions of the wire and the fitting mechanism 3 at both ends, and the pulling force is evenly diffused, avoiding concentrated action on the fixed position and improving the tensile strength. Specifically, when the jumper wire is impacted, since the length of the second connecting rope 19 is shorter than the length of the rubber sleeve 1, the second connecting rope 19 will be straightened first. At this time, the spring 16 can be pulled by the second connecting rope 19, and then the buffer effect can be achieved by means of the spring 16. At the same time, through each insertion column 22 at the other end of the second connecting rope 19, the pulling force can be directly applied to the rubber sleeve 1 at different positions, and the impact force can be dispersed to multiple different points by means of the rubber sleeve 1, thereby reducing the problem of the jumper wire breaking.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
