Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it should be understood by those skilled in the art that the embodiments described below are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

When connecting the optical cable and connecting, need to use fixed cover to fix the cable leather to direct tractive optic fibre and damage the wire jumper structure when avoiding the optical cable to receive the tractive effect. In order to enhance the connection strength of the fixing sleeve and the cable sheath, the cable sheath and the rear end point of the fixing sleeve can be fixed by gluing. However, the glue dispensing fixing mode has the problems that the glue dispensing amount is not easy to control, the fixing efficiency is low, the dismounting is inconvenient and the like.

In view of the above-mentioned problems, the present invention adopts a manner in which the center jacket is inserted at the front end of the optical cable so that the cable sheath is fixedly clamped between the center jacket and the fixing jacket, thereby improving the connection strength of the fixing jacket and the cable sheath. Because the central sleeve is arranged on the inner side of the cable sheath, when the fixed sleeve is subjected to compression joint operation, the central sleeve can effectively support the cable sheath outwards so that the cable sheath is in full contact with the fixed sleeve, and the fixed sleeve which is deformed due to compression joint can better fix the cable sheath on the central sleeve in a compression joint mode. Through the compression joint mode, the central sleeve and the fixed sleeve can be matched to clamp and fix the cable sheath, so that the connection strength of the cable sheath and the fixed sleeve can be effectively improved, and the tensile property of the optical cable is effectively improved. Furthermore, the mode that the front end of the optical cable is inserted into the center sleeve is used for supporting and fixing, so that the production difficulty is simplified, and the production efficiency can be effectively improved.

The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the utility model.

An embodiment of the optical fiber jumper structure provided by the present invention will be described below with reference to fig. 1 and 2.

The optical fiber jumper structure may include a fiber optic cable and a connector, where the connector may be disposed at a front end of the fiber optic cable, and the connector is also known as a "splice". In use, the optical fiber jumper structure of the utility model can be used for butt-assembling the connector with a corresponding adapting connector, thereby transmitting corresponding optical signals.

As shown in fig. 1 and 2, the optical cable has optical fibers 3, a reinforcing filler, and a sheath 1, wherein the optical fibers are located at the center of the optical cable as a core, and the optical cable is divided into a single core and a multi-core according to the number of the cores. The strength filler is located between the optical fiber 3 and the cable jacket 1 and extends along the length of the cable to increase the tensile strength of the entire cable. In this embodiment, the reinforcing filler is specifically an aramid filler 2, and the aramid filler 2 may specifically select kevlar aramid fiber. The cable skin 1 forms an outer protection wrapping structure of the optical cable, and the cable skin 1 can be made of soft materials, particularly polyvinyl chloride materials.

In order to improve the bonding strength between the cable sheath 1 and the fixing jacket 4, as shown in fig. 1 and 2, a center jacket 5 is inserted into the front end of the optical cable, the center jacket 5 is loosely fitted over the optical fiber 3 and inside the cable sheath 1, so that the center jacket 5 is located between the optical fiber 3 and the cable sheath 1, and a reinforcing filler is also located outside the center jacket 5. The inner diameter of the central sleeve 5 is such as to allow the optical fibre 3 to pass through the inner bore of the central sleeve 5 and to avoid scratching the surface of the optical fibre.

The center jacket 5, which is inserted into the optical cable, supports the sheath 1, and thus, the outer diameter of the center jacket is smaller than the inner diameter of the sheath 1. As shown in fig. 1 and 2, the center sleeve 5 has a supporting sleeve body 51, and the front end of the supporting sleeve body 51 is provided with an outward-turning structure 52, where the outward-turning structure 52 is embodied as an annular turned edge. Moreover, in order to prevent scratching the outer surface of the optical fiber 3, the inner circumferential surface of the connection part of the annular turned edge and the supporting sleeve body 51 is a smooth transition surface. Due to the arrangement of the annular turning edge, the front end of the central sleeve 5 forms a horn structure.

Specifically, when the center jacket 5 is inserted into the front end of the optical cable, the reinforcing filler and the sheath 1 are supported by the jacket body 51. To ensure sufficient support, the core jacket 5 is typically made of a hard material, such as a metal material, to form a hard metal jacket that provides sufficient support for the cable jacket 1 and the reinforcing filler.

For the connector, the connector includes a housing 6, and signal contacts are provided in the housing 6. When the connector is attached to the front end of the optical cable, the optical cable is advanced into the housing 6 and mated with the signal contacts to transmit optical signals.

The rear end of the shell 6 is provided with a fixed pipe section 61, the fixed pipe section 61 is in threaded connection with a fixed sleeve 4, and the fixed sleeve 4 is used for crimping and fixing the cable sheath 1 to fixedly assemble the optical cable and the connector together. The outer peripheral surface of the fixed pipe section 61 is provided with external threads, and correspondingly, the corresponding part of the fixed sleeve 4 is provided with internal threads so as to conveniently realize the thread fixed connection of the fixed sleeve 4 and the fixed pipe section 61.

The fixing sleeve 4 here extends overall in the front-rear direction, the fixing sleeve 4 comprising a front socket section 41 and a rear crimping section 42. The front sleeve section 41 has an internal thread to be fixedly connected with the fixed pipe section 61 on the housing 6 by a thread, so that the fixed sleeve 4 is sleeved outside the housing 6. The rear crimping section 42 is used for crimping and sleeving the cable sheath 1, so that the rear crimping section 42 and the central sleeve 5 are matched to clamp and fix the cable sheath 1 and the reinforcing filler. Based on the arrangement, when the crimping and fixing operation is carried out, the rear crimping section 42 is deformed by crimping, and the cable sheath 1 and the reinforcing filling piece can be crimped and fixed on the central sleeve 5, so that the fixed sleeve 4, the cable sheath 1, the reinforcing filling piece and the central sleeve 5 are relatively fixed and assembled together, the connection strength of the optical cable and the fixed sleeve 4 can be effectively improved, and the tensile strength of the optical fiber jumper structure can be effectively improved.

Generally, since the inner diameter of the fixed pipe section 61 is larger than the outer diameter of the optical fiber, the outer diameter of the fixed pipe section 61 is larger than the outer diameter of the cable sheath 1, and the inner diameter of the front socket section 41 is also larger than the inner diameter of the rear crimping section 42. In consideration of the factors of the inner diameter and the outer diameter, as shown in fig. 1, the front crimping section 41 and the rear crimping section 42 of the fixing sleeve 4 are in transition connection through a conical structure, so that the internal stress is small, the service life is long, and the scratch on the reinforcing filler on the inner side is avoided.

Regarding the central sleeve 5, in order to further improve the crimping fixing strength of the fixing sleeve 4 to the cable sheath 1, the length of the central sleeve needs to be designed reasonably, so that when the fixing sleeve 4 completes the crimping fixing operation, the front end of the central sleeve 5 is pushed forward to be matched with the shell 6. For this purpose, the cable jacket 1 is clamped and fixed in the radial direction of the cable by a fixing sleeve 4 and a central sleeve 5. When the fixing sleeve 4 is pressed, the pressing deformation drives the cable sheath 1 and the center sleeve 5 to move forward together, so that the front end of the center sleeve 5 abuts against the shell 6 to be pushed forward to be matched with the shell 6. The central sleeve 5 and the fixing sleeve 4 can be relatively fixedly assembled together in the length direction (i.e. the front-back direction) of the optical cable by using the shell 6, so that the fixing strength of the fixing sleeve 4, the cable sheath 1 and the central sleeve 5 is further improved.

In some embodiments, as shown in fig. 1 and 2, the annular flange at the front end of the support sleeve body 51 of the center sleeve 5 is used for forward pushing engagement with the housing 6, limiting the forward and backward position of the center sleeve 5. The annular turning edge is arranged at the position to be conveniently matched with the rear end face of the shell 6 in a pushing mode, so that the processing is convenient, and large pushing acting force can be borne.

It should be noted that, in order to realize the fixing manner of the fixing sleeve 4 and the central sleeve 5 in the utility model to clamp the cable sheath 1 cooperatively, the length of the central sleeve needs to be designed reasonably, i.e. the length should not be too long or too short. For example, if the center jacket is too short, the supporting area provided to the cable sheath is small, which may affect the supporting effect and may not improve the connection strength rapidly. For this reason, the front-rear length of the center sleeve 5 may be equal to or greater than two-thirds of the front-rear length of the rear crimping section 42. In addition, the center cover 5 does not affect the supporting effect and the connecting strength when it is too long, but the appearance is not beautiful and the cost is increased. In view of this, the present invention proposes that the front-rear length of the center sleeve 5 is not greater than the front-rear length of the rear crimping section 42, so that the rear end of the center sleeve 5 is located inside the fixing sleeve 4.

In some embodiments, as shown in fig. 1, the aramid fiber filler 2 as the reinforcing filler extends forward, and is not only padded between the cable jacket 1 and the central sheath 5, but also the front end of the aramid fiber filler 2 is sandwiched between the fixing tube section 61 of the casing and the front socket section 41 of the fixing sheath 4, and the aramid fiber filler 2 and the casing can be pressed and fixed together by the front socket section 41. Here through compressing tightly aramid filler 2, can further improve the connection to the optical cable, improve the tensile strength of whole optical cable.

When the optical fiber jumper structure is manufactured, the central sleeve 5 can be inserted at the front end of the optical cable, the central sleeve 5 is sleeved outside the optical fiber 3, the processed aramid fiber filling part 2 covers the central sleeve 5, the fixed sleeve 4 is sleeved outside the optical cable, and then the optical cable is connected with the connector.

When connecting the cable to the connector, the optical fiber 3 is threaded into the housing 6 to be connected with the corresponding contact inside the connector. The aramid fiber filling member 2 is covered on the outer peripheral surface of the fixed pipe section 61 at the rear end of the shell 6, then the fixed sleeve 4 is pushed to the shell 6 from back to front, the fixed sleeve 4 is rotated to enable the fixed sleeve 4 to be in threaded connection with the fixed pipe section 61, and at the moment, the aramid fiber filling member 2 can be fixed outside the fixed pipe section 61 in a compression joint mode through the fixed sleeve 4.

The compression joint operation is carried out on the fixed sleeve 4 by utilizing the compression joint tool, the rear compression joint section 42 at the rear part of the fixed sleeve 4 is deformed by compression joint, the cable skin 1 and the aramid fiber filling piece 2 are compressed and connected outside the central sleeve 5 when the rear compression joint section 42 is deformed in an inward shrinkage mode, meanwhile, the central sleeve 5 is forced to move forwards to push the rear end face of the shell 6, compression joint fixation in the radial direction of the optical cable is achieved, fixation of the central sleeve 5 is achieved in the axial direction of the optical cable, the connection strength of the fixed sleeve 4, the optical cable and the connector can be effectively improved, and the cable skin 1 is effectively prevented from falling off.

In the embodiment, the supporting and fixing are realized by inserting the central sleeve into the front end of the optical cable, so that the production difficulty is simplified, and the production efficiency can be effectively improved. In addition, the optical fiber jumper structure is convenient to maintain and replace in the assembling mode of inserting the central sleeve at the front end of the optical cable. When the optical fiber jumper wire structure has a problem, the fixing sleeve is firstly detached from the shell and the optical cable when the optical cable is determined to be damaged or the connector is determined to be damaged, and then the damaged optical cable or connector is replaced, so that the overall maintenance cost is low.

In some embodiments, the everting structure of the front end of the center hub may be an annular everting structure as shown in fig. 2. In other embodiments, the outward turning structure at the front end of the central sleeve can also adopt a plurality of outward turning support claws, and a plurality of outward turning support claws can be sequentially distributed at intervals along the circumferential direction of the central sleeve. When the central sleeve is assembled outside the optical fiber and the crimping operation is completed, the outward-turning supporting claws push the rear end face of the shell forward. Because the outward turning supporting claws are separated from each other, attention needs to be paid to the material of the central sleeve at the moment so as to ensure the supporting strength of the outward turning supporting claws. In other embodiments, reinforcing ribs can be arranged between the outward turning supporting claws and the outer peripheral surface of the supporting sleeve body to improve the strength of the outward turning supporting claws and avoid the influence of random deformation of the outward turning supporting claws on the connection strength.

In some embodiments, the everting structure of the front end of the center hub may be as shown in figure 1. In other embodiments, an eversion structure at the front end of the central sleeve can be omitted, and at the moment, the outer diameter of the central sleeve is increased, so that the outer side edge of the front end of the central sleeve can be pushed forwards on the rear end face of the shell, and the pushing matching of the front end of the central sleeve and the shell can also be realized. In specific implementation, the outer diameter of the central sleeve can be increased by adopting the following two modes: one is to increase the wall thickness of the central sleeve, and realize the pushing fit with the rear end face of the shell under the condition that the inner diameter of the central sleeve is not increased. The other method is to directly increase the inner diameter of the central sleeve, and under the condition that the wall thickness is basically unchanged, the outer diameter of the central sleeve can be enlarged so as to realize the pushing fit with the rear end face of the shell.

In some embodiments, as shown in fig. 1, the front-to-back length of the center hub is no greater than the front-to-back length of the rear crimping section so that the rear end of the center hub is located inside the retaining sleeve. In other embodiments, the front-back length of the central sleeve can be larger than that of the back compression joint section, so that the central sleeve penetrates out of the fixing sleeve backwards, the central sleeve can provide enough supporting area for the cable sheath, and the connection strength of the fixing sleeve, the cable sheath and the central sleeve can meet the requirement.

In some embodiments, as shown in FIG. 1, the front-to-back length of the center hub is equal to or greater than two-thirds of the front-to-back length of the rear crimp section. In other embodiments, the front length and the rear length of the central sleeve can be relatively reduced, the jumper structure is suitable for being applied to an environment with a good use environment, and the whole optical cable is not easy to be subjected to a traction effect or is subjected to a small traction acting force, so that the requirement of practical application is met.

In some embodiments, as shown in fig. 1, aramid fillers are used as the reinforcing filler. In other embodiments, the reinforcing filler may also be other fillers, such as low-carbon galvanized steel wires, or FRP reinforcing cores, so that the corresponding reinforcing filler is conveniently filled between the front splicing section of the fixing sleeve and the fixed pipe section of the housing, and is conveniently filled in front of the cable sheath and the central sleeve.

In some embodiments, the fixing sleeve is a metal sleeve, which is convenient for providing enough supporting force. In other embodiments, the fixing sleeve can be a non-metal sleeve as long as enough supporting force can be provided to expand the cable sheath outwards.
