The sealing plug 2 is arranged in the mounting groove 11, the optical cable passes through the sealing plug 2, the sealing plug 2 is made of rubber, the joint can be effectively sealed, and the shape of the sealing plug 2 can be designed into a plurality of forms such as no hole, two holes, three holes and the like according to the use requirement so as to adapt to different use requirements.
Two wire winding subassemblies set up in box body 1, and every wire winding subassembly includes:
A base plate 3 provided with two base winding areas 31, wherein a plurality of base wire clamping grooves 32 are arranged at the outermost circumferential edge of each base winding area 31, and the notches of the base wire clamping grooves 32 face the base winding areas 31;
The first fixer 4 is provided with a plurality of first clamping grooves extending along the length direction of the box body 1, and the first clamping grooves clamp the protective sleeve of the optical fiber splicing point to prevent the splicing point from being broken due to the problems of torsion, stretching and the like of the optical fiber splicing point;
The expansion coil 5 is provided with two expansion winding areas 51, each expansion winding area 51 is arranged in a corresponding base winding area 31, the radius of each expansion winding area 51 is smaller than that of the corresponding base winding area 31, the height of each expansion winding area 51 is higher than that of the corresponding base winding area 31, and a groove body is formed between each expansion winding area 51 and the corresponding base winding area 31;
the second fixer 6 is arranged between the two extension winding areas 51, and is provided with a plurality of second clamping grooves forming a certain included angle with the length direction of the box body 1;
the cover plate 7 is rotatably mounted on the base plate 3.
The specific use method of the splice box comprises the steps of penetrating two optical cables to be spliced through the sealing plugs 2 (according to the arrangement condition of field cables, the two cables can penetrate into the box body 1 from the same sealing plug 2 or penetrate from the middle of two different sealing plugs 2), stripping the outer rubber layer of the optical cable extending into the box body 1 to expose the optical fibers, and if the optical cable is an optical cable which is basically not dismantled (such as a user optical cable, etc.), placing an optical fiber splicing point in a first clamping groove after splicing is finished, then winding a reserved part of the optical fiber on a foundation disc 3 along the outer sides of two foundation winding areas 31 in a ring shape, winding the reserved optical cable into a flat O shape, and placing the reserved optical fiber into a foundation clamping groove 32 to fix the position of the reserved optical fiber.
If the optical cable is to be frequently disassembled (such as a debug optical cable) or is to be newly added in a subsequent expansion, in order to avoid interference between the optical fibers and the optical fibers in the previous stage, as shown in fig. 5, the connection points of the optical fibers are required to be placed in a second clamping groove, then the reserved optical fibers are wound into an 8 shape on the expansion disc 5 along the circumferential directions of the two expansion winding areas 51, and the reserved optical fibers are placed in the expansion clamping groove 52 to fix the positions of the reserved optical fibers.
Through the combination of the foundation disc 3 and the expansion disc 5, the optical cable presents different detouring modes on the surface of the optical cable, two groups of cables can be effectively separated, and the sealing plug 2 can be replaced according to the use requirement of the site, so that the box body can maintain good sealing performance before and after capacity expansion. The two winding assemblies can further divide the cable, such as one for installing the optical cable fiber of the old user and the other for installing the optical cable fiber of the new user in the capacity expansion process, in the subsequent use, the optical fiber of the old user can be damaged earliest due to relatively long use time, and the other winding assembly can be not moved in the maintenance process, so that the damage to the new optical fiber is avoided.
In order to facilitate replacement of the sealing plug 2 during capacity expansion, the connector box has a special design on the structure of the sealing plug 2, as shown in fig. 7, the sealing plug 2 comprises a first split body 21 and a second split body 22, and the first split body 21 and the second split body 22 clamp the optical cable along the height direction of the box body 1, so that the installed optical cable does not need to be dismantled during capacity expansion of the optical cable. Two wire clamping grooves are formed in the first split body 21 and the second split body 22 respectively, protruding sealing ribs are arranged in the wire clamping grooves, the optical cable is placed in the wire clamping grooves, and after the optical cable is installed, the sealing ribs and the outer side of the optical cable form interference fit, so that sealing is achieved. Under the structure, a plurality of sealing plugs 2 and the first split body 21 and the second split body 22 of each sealing plug 2 can be arranged to form different numbers of wire clamping grooves so as to meet different use requirements, and a plurality of wire clamping grooves can be formed in the first split body 21 and the second split body 22 of one sealing plug 2, and then solid rubber columns with the same diameter as the optical cable are plugged into the wire clamping grooves which are not needed to be used, so that corresponding parts are plugged.
Preferably, the inner wall of the installation groove 11 and the outer side surface of the sealing plug 2 are gradually folded outwards along the inside of the box body 1, and the inner wall of the installation groove 11 is attached to the outer side surface of the sealing plug 2. The structure can realize further sealing at the sealing plug 2 and protect the optical cable, and the specific principle is that because the optical cable is usually pulled outwards, under the structure, if the optical cable is pulled outwards, the sealing plug 2 is driven to move outwards, at the moment, the inner wall of the mounting groove 11 gradually folded outwards can enable the first split body 21 and the second split body 22 to be tightly attached, and the friction force on the optical cable can be rapidly increased, so that the movement of the optical cable is restrained, and the optical fiber in the box body 1, especially the optical fiber connection point, can not be pulled by external force.
Preferably, the sealing plug 2 further comprises an elastic connecting section 23, two ends of the elastic connecting section 23 are respectively connected with the first split body 21 and the second split body 22, and the elastic connecting section 23 can enable the sealing plug 2 to be an integral part, so that the first split body 21 and the second split body 22 are prevented from being lost during disassembly.
In the conventional splice closure, the winding assembly is usually fixed to the closure, and since the optical cable is internally provided with a plurality of smooth optical fibers, even though the outermost rubber layer of the optical cable is fixed, the optical fibers in the interior of the splice closure tend to be pulled outwards to some extent along with the movement, bending and other actions of the optical cable, and at this time, the optical fibers in the closure are pulled to cause breakage of the splice. In order to solve the problems, the connector box adopts the following structure:
both winding assemblies are not fixedly placed in the box body 1;
The base plate 3 is provided with hooks 81 at both ends along the length direction of the box body 1, and the elastic connection section 23 is hooked on the hooks 81 and is in a tight state.
Through this kind of structure, make the wire winding subassembly wholly receive the pulling force and have had certain rotation space, when optic fibre was outwards drawn, the optic fibre that the power will be through twining in the wire winding subassembly transmits the wire winding subassembly, makes wire winding subassembly produce certain rotation to avoid optic fibre to be drawn excessively and lead to the fracture. Meanwhile, when the outer layer of the optical cable is pulled outwards, the sealing plug 2 clamps the optical cable, the elastic connecting section 23 at the other end firstly inhibits the sealing plug 2 at the position from moving outwards too much, so that excessive pressing force is avoided to the optical cable by the sealing plug 2, when the external force is removed, if the clamping force is not released, the sealing ribs in the sealing plug 2 can continuously press the optical cable to press the inner optical fiber, and at the moment, if the problem that the optical fiber is pulled outwards occurs at the other sealing plug 2, the optical fibers at the two ends are in a tensioned state, and the optical fibers are easy to break. Under the structure, when the force pulling the outer layer of the optical cable is removed, the elastic connecting section 23 at the other end pulls the whole winding assembly and the sealing plug 2 to move inwards until the tensile forces of the two elastic connecting sections 23 are the same, so that the clamping force of the sealing plug 2 is relieved, and the excessive clamping force on the optical cable is avoided.
Although the winding component in the connector box needs to be not fixedly arranged, the problem that the winding component is too large to shake to cause a new problem needs to be avoided, and therefore the connector box is internally provided with:
the two ends of the foundation disc 3 are respectively provided with a sliding plate 82 and a clamping plate 83, wherein the sliding plate 82 slides along the length direction of the box body 1, and the clamping plate 83 and the hook 81 are fixedly connected with the sliding plate 82;
Two limit grooves 12 are formed in the inner wall of each side of the box body 1 and are positioned at two ends of the winding assembly, and openings of the limit grooves 12 are opposite;
After the elastic connecting section 23 is hooked on the hook 81, the two sliding plates 82 are driven to move to the limit position towards the outer side of the box body 1, and at the moment, the two clamping plates 83 respectively extend into the corresponding limit grooves 12, so that the movement of the foundation disc 3 is limited, and only rotation can be generated without shaking;
After the elastic connecting section 23 is taken off from the hook 81, the two sliding plates 82 are manually pushed to move to the limit positions towards the inner side of the box body 1, and at the moment, the two clamping plates 83 are moved out of the corresponding limit grooves 12, so that the foundation disc 3 can be taken down, the winding assembly can be separated from the box body 1, and the operation of personnel is facilitated.
In order to better limit the optical fibers and avoid the mutual interference of the optical fibers in the base winding area 31 and the extension winding area 51, a plurality of wire-dividing posts are preferably arranged between the boundaries of the base winding area 31 and the extension winding area 51 in the winding assembly, the wire-dividing posts are far away from the extension winding area 51 when the sliding plate 82 moves towards the outer side of the box body 1 (namely, after the installation is completed, the elastic connecting section 23 is sleeved on the hook 81), so that the optical fibers in the base winding area 31 can not move towards the extension winding area 51, and the wire-dividing posts are close to the extension winding area 51 when the sliding plate 82 moves towards the inner side of the box body 1, so that a space for taking and placing the optical fibers in the base winding area 31 is reserved, and the operation and the control are facilitated for personnel.
Since only the sliding plate 82 can be used as a branch column power source in the winding assembly, the moving path of the branch columns at different positions is not necessarily the same as that of the sliding plate 82, so that a plurality of branch lines are required to be split into a first branch column 84 and a second branch column 85;
The first split columns 84 are arranged at two ends of the base plate 3, and the first split columns 84 are similar to the sliding plate 82 in movement along the length direction of the box body 1, so that the first split columns 84 are fixedly connected with the sliding plate 82;
The second branch 85 needs to be located at the center of the winding assembly, and the second branch 85 moves along the width direction of the box body 1, so that the first waist hole 33 extending along the width direction of the box body 1 needs to be arranged at the middle section of the base plate 3, and the second waist hole 82a extending along the direction forming a certain angle with the width direction of the box body 1 needs to be arranged at the sliding plate 82, so that the second branch 85 can pass through the first waist hole 33 and the second waist hole 82a at the same time, and the action of the second branch 85 can be realized.
Preferably, both ends of the first clamping groove are simultaneously bent towards the inner side or the outer side of the box body 1, so that the first clamping groove forms a V shape, thereby ensuring that a stronger clamping effect is generated on the protective sleeve of the optical fiber splicing point, and avoiding the optical fiber splicing point from being separated from the first clamping groove during the dismounting and rotating actions of the winding assembly.
The box 1 is preferably designed as a first housing and a second housing which can be fixedly connected to each other, such a split design enabling a person to perform the mounting and wiring operations more conveniently. The face that can laminate with the second casing on first casing sets up the seal groove, and the face that laminates with first casing on the second casing sets up sealing rib, and sealing rib stretches into in the seal groove, increases the leakproofness of two casing laminating faces through this kind of mode to protect the inside optic fibre of box body 1 better.
The foregoing has outlined and described the basic principles, features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
