Description

Optical cable connecting device

Technical Field

The application relates to the technical field of communication equipment, in particular to an optical cable connecting device.

Background

At present, networks are secret and inseparable from everyone, and the networks are basically required to be fully covered in house buildings, and the networks are registered. The general Network signal transmission is realized by transmitting Optical signals through Optical fibers, and an Optical Distribution Network (ODN) is required to realize fiber Network home entry. An Optical distribution Network is an Optical signal distribution Network located between an Optical Line Terminal (OLT) and an Optical Network Terminal (ONT). An optical Distribution network can be divided into a feeder Terminal, a Distribution Terminal and a subscriber Terminal from end to end, and an optical transmission node at the subscriber Terminal generally consists of a corridor Distribution Box (FDB) and an Access Terminal Box (ATB). The corridor fiber distribution box is one of the fiber distribution boxes, is an interface device for connecting a trunk optical cable and a distribution optical cable, is usually deployed in a corridor, and has functions of optical fiber light splitting, distribution, home entry and the like.

The fiber distribution box of the related art has a specific structure as shown in fig. 1, and includes a housing 01, wherein the housing 01 has an opening, and a cover 02 is rotatably connected to the opening. The opening of the case 01 can be covered by rotating the cover 02. When a plurality of optical cables need to be accessed, the cover 02 is opened, the optical cables extend into the opening of the shell 01 and are connected to corresponding positions, after the connection is completed, the cover 02 is rotated, the optical cable interface is protected, and meanwhile, the cover 02 is provided with a plurality of notches 021, and the optical cables can pass through the notches 021. Referring to fig. 2, a hook 022 is arranged on the cover 02, a slot 011 is arranged at a position of the housing 01 corresponding to the hook 022, and when the cover 02 covers the opening of the housing 01, the hook 022 is correspondingly clamped into the slot 011, so that the cover 02 and the housing 01 can be fixed at a relative position, and internal components of the fiber distribution box are protected.

Referring to fig. 2, the hook 022 is integrated with the cover 02, the slot 011 is also directly opened on the housing 01, the hook 022 and the slot 011 are connected by the material characteristic of the structure itself, and the hook 022 is clamped into the corresponding slot 011 by deformation when being acted by force. Similarly, when the locked state of the cover 02 and the housing 01 is to be unlocked, external force needs to be applied forcibly to deform the hook 022 or deform the entire cover 02, so that normal unlocking can be performed. Therefore, the clamping hook 022 and the clamping groove 011 are easily damaged after long-term use for many times, so that the cover 02 and the shell 01 cannot be normally locked; moreover, because unblock and locking can only rely on the deformation of material itself, for convenient unblock and locking, the joint reliability of trip 022 and draw-in groove 011 can not be done too strongly, otherwise can not normal locking and unblock. Therefore, the cover 02 and the housing 01 of the fiber distribution box of the related art are not highly reliable in clamping and are easily damaged.

Disclosure of Invention

The embodiment of the application provides an optical cable connecting device, and the joint structure reliability of safety cover and box body is high, and not fragile.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, an embodiment of the present application provides an optical cable connection apparatus, including:

the box body is provided with an opening, a movable component is arranged in the box body and close to the opening, and the movable component can move relative to the box body;

the protective cover is rotatably connected with the opening of the box body, and a clamping structure is arranged between the movable assembly and the protective cover;

the protective cover can cover the opening of the box body when rotating relative to the box body, and the clamping structure is used for fixing the relative positions of the box body and the protective cover; when the movable assembly is operated to move relative to the box body, the clamping structure is disengaged.

According to the optical cable connecting device provided by the embodiment of the application, due to the arrangement of the movable assembly, when the box body and the protective cover are required to be opened, the movable assembly can be operated to move relative to the box body, so that the clamping structure between the box body and the protective cover is separated, and the protective cover can be opened. Certainly, when box body and safety cover joint are needed, also can be through controlling movable assembly for the box body motion, the mutual joint department of joint structure between box body and the safety cover can avoid, treat that the safety cover further moves to the joint department of joint structure and when moving to the position that can the joint, make movable assembly for the box body motion once more to make joint structure joint. Therefore, the movable assembly can move relative to the box body through operation, the box body and the protective cover can be unlocked and clamped, and compared with the scheme of forcibly applying external force to deform the structure at the clamping position to unlock in the related technology, the structure at the clamping position cannot deform greatly, and the clamping structure cannot easily reach the fatigue limit and cannot be damaged easily; on the other hand, because the unblock of joint structure is realized through the motion of movable assembly, and then can do the joint reliability of joint structure higher, and when not worrying that joint department intensity is too high, the difficult deformation that takes place of material characteristic itself leads to the circumstances that can not the joint or can not the unblock to take place.

In a first possible implementation manner of the first aspect, the movable assembly includes a sliding rod and a first elastic member, the sliding rod extends in a direction parallel to the rotation axis of the protection cover, and when the sliding rod is operated to move relative to the box body, the first elastic member is set in an elastic deformation state. The movable assembly can be realized in various modes, and the effect of unlocking the clamping structure can be realized as long as the position of the movable assembly can be changed. Taking the motion mode as an example, the motion mode of the movable assembly may be sliding or rotating, and the like, in comparison, the rotating mode requires a larger motion space, and the sliding mode occupies a small space, is relatively easy to implement, and is convenient for a user to operate. Based on sliding motion's mode, it is specific can include slide bar and first elastic component, and when the slide bar was operated to slide, first elastic component was in elastic deformation state to provide the resilience force, and then, can realize the slide bar for the slip of box body and reply the motion, can be applicable to the scheme of the joint structure of sliding motion unblock. The first elastic piece is in an elastic deformation state, can be in an elastic compression state, can also be in an elastic stretching state, and can also be in an elastic torsion state.

In a second possible implementation manner of the first aspect, one end of the sliding rod, which is close to the outer side of the box body, is an operation end, and the sliding rod can move relative to the box body by pressing the operation end, so that the clamping structure is separated. When the movable assembly comprises the sliding rod and the first elastic piece, in order to realize the scheme that the clamping structure is disconnected when the movable assembly is operated to move relative to the box body, an operable position is required to be arranged on the sliding rod firstly, so that the movable assembly is convenient for a worker to operate. Set up the structure that can supply the operation on the slide bar, can be at the optional position of slide bar, for example, at the middle part or both ends etc. of slide bar, compare, the middle part of slide bar is located the box body inside, and the staff is difficult for touching, and sets up the position at the both ends of slide bar and realize more easily, and the action of the tip of operation slide bar is for pressing the action, and the transmission of power is more high-efficient, realizes and makes things convenient for the staff to operate easily. Therefore, one end of the sliding rod close to the outer side of the box body is an operation end.

In a third possible implementation manner of the first aspect, the operation end of the sliding rod is located in the box body, an operation hole is formed in the position, corresponding to the operation end of the sliding rod, of the box body, and the shape of the operation hole is matched with the outer contour of the unlocking tool. The operating end of slide bar can expose, also can hide, under the sufficient condition in space of the position both sides of minute fine box installation, in order to avoid non-staff's condition that can unblock and open optical cable connecting device at will to take place, can hide the operating end of slide bar, and the specialized tool through the staff stretches into the operating end that the handle hole could touch the slide bar, could carry out the unblock operation of joint structure. Furthermore, only by the special tool, the clamping structure can be unlocked and the fiber distribution box can be opened, so that the situation that non-workers can unlock and open the optical cable connecting device at will is effectively avoided.

In a fourth possible implementation manner of the first aspect, the inner contour of the operation hole may be any one of a circle, a line, a cross and a hexagon. When the operation end that sets up operation hole and slide bar is hidden in the box body, the operation of opening branch fine box must adopt the instrument to stretch into in the operation hole and touch the slide bar just can, and the instrument will stretch into the operation hole, must be the outline of instrument and the interior profile phase-match of operation hole. Thus, the shape of the inner contour of the handling hole is provided with a plurality of realizations, and the corresponding tool is also matched with the handling hole. For example, the shape of the inner contour of the operation hole may be any one of a circle, a line, a cross and a hexagon, wherein the circle is more conventional, and the matched tool may be a rod-shaped tool having a diameter smaller than that of the operation hole; the tool corresponding to the straight line shape can be a straight screwdriver; the tool corresponding to the cross shape can be a cross screwdriver; the hexagonal counterpart tool may be a hex wrench. Of course, the arrangement shape of the operation hole and the corresponding tool are just some examples, the shape of the operation hole may be other special shapes, even irregular special-shaped holes, and the tool corresponding to the operation hole may also be a special shape, and is not limited to a screwdriver and a wrench, etc. commonly used by a worker, for example, a matched special-shaped key tool, etc.

In a fifth possible implementation manner of the first aspect, an adapting hole is formed in a position of the box body, which corresponds to the operating end of the sliding rod, and the operating end of the sliding rod passes through the adapting hole and extends out of the box body. The fiber distribution box is generally installed in a house building and outside a resident room, for example, in a corridor, the space form in the corridor is complex, the installation position of the fiber distribution box can be relatively open or narrow, when the space on two sides of the installation position of the fiber distribution box is narrow, a tool (such as a screwdriver) may not have enough space to unlock the optical cable connecting device, therefore, based on the requirements of installation and unlocking in the space, the operation end of the sliding rod can penetrate through the adaptive hole of the box body to extend out of the box body, and a worker can conveniently operate and unlock the fiber distribution box by hand.

In a sixth possible implementation manner of the first aspect, one end of the sliding rod is an operating end, the other end of the sliding rod has a receiving groove, one end of the first elastic member is located in the receiving groove, and the other end of the first elastic member abuts against the inner side of the box body. In order to easily realize the operation unlocking of the sliding rod, the sliding rod only needs to be provided with one end which is set as an operation end, the other end is connected with the first elastic piece, and the unlocking can be realized through the operation end of the sliding rod arranged on one side wall of the box body. Namely, the one-sided unlocking is realized, the structure is simple, and the realization is easy.

In a seventh possible implementation manner of the first aspect, both ends of the sliding rod are close to the outer sides of the box body and are both operation ends, the outer sides of both ends of the sliding rod are provided with circumferential limiting steps, and the two first elastic pieces are respectively sleeved on the outer sides of both ends of the sliding rod and abut against the circumferential limiting steps. As mentioned above, there is a great uncertainty about the space around the fiber distribution box after installation, and the setting position of the operation end of the slide lever and the position where the unlocking operation is possible are correspondingly set for different installation positions. For example, if the fiber distribution box is installed with at least two side walls close to each other, then if the operation end of the cable connection device is unlocked from one side, the unlocking position is likely to be blocked, and the fiber distribution box cannot be unlocked. Or two different single-side unlocking fiber distribution boxes need to be arranged so as to be suitable for the conditions of different space positions. This has just increased manufacturing cost again, and the staff need carry two kinds of branch fine boxes of different specifications in advance, and the construction is very inconvenient. From this, can all be close to the outside of box body with the both ends of slide bar, and be the operation end, and the both ends of slide bar have all cup jointed first elastic component, like this, divide the both sides of fine box to all can carry out the unblock operation, two side unblocks have avoided dividing fine box one side to be blockked and the problem that can not the unblock appears.

In an eighth possible implementation manner of the first aspect, the sliding rod comprises a first part and a second part, and the first part and the second part are connected through a protrusion and a recess; the sliding rod is a rod-shaped structure, and can be manufactured and assembled separately for the convenience of assembly of the rod-shaped structure.

In a ninth possible implementation manner of the first aspect, in order to save materials and reduce cost, the sliding rod may be a hollow structure. Meanwhile, in order to ensure the strength of the sliding rod with a hollow structure, a plurality of ribs are arranged in the hollow space inside the sliding rod.

In a tenth possible implementation manner of the first aspect, a plurality of optical fiber adapters are arranged at the opening of the box body, the optical fiber adapters are used for being inserted into the optical cable connectors, baffles are arranged on two sides of the protective cover corresponding to each optical cable connector, and a coverage area of a projection of each baffle facing the optical cable connector is larger than or equal to a coverage area of the corresponding optical cable connector. Because divide fine box to be the equipment with optical fiber signal distribution, the interface of its wiring often has a lot, arranges the opening part at the box body often, and when dividing fine box cover, need reserve the position of dodging of interface wiring, like this, there is the risk of being pulled out by the mistake at the interface of optic fibre cable and inserting. According to the characteristics of the optical fiber cable and the conventional interface, after the optical fiber cable is plugged into the corresponding interface, the optical fiber cable cannot be pulled out as long as the optical fiber cable cannot be pinched to the outer side of the connector of the optical fiber cable by hands. Therefore, in order to pull out and insert the optical fiber cable by non-working personnel at will, the two sides of the protective cover corresponding to each optical cable connector are respectively provided with a baffle, and the coverage range of the projection of the baffle towards the optical cable connector is larger than or equal to that of the optical cable connector. Like this, when the optical cable is pegged graft in the optical fiber adapter, the baffle keeps off the both sides at the optical cable connector, and then when making not opening the safety cover, the unable lateral wall that touches the optical cable connector of people's finger, and then can not pull out at will and insert the optical cable.

In an eleventh possible implementation manner of the first aspect, the clamping structure includes a first clamping hook disposed on the movable assembly and a second clamping hook disposed on the protective cover. The clamping structure arranged between the movable assembly and the protective cover can be realized in various modes, for example, the clamping structure can be in a mode of clamping a first clamping hook and a second clamping hook, can also be in a mode of clamping a clamping hook and a clamping groove, or can also be in a mode of clamping a clamping hook and a clamping hole, and the like.

In a twelfth possible implementation manner of the first aspect, the second hook may be a groove structure, the first hook is clamped into the groove structure, and the side wall of the groove structure may limit the relative position of the first hook, so that the connection after the clamping is more reliable.

In a thirteenth possible implementation manner of the first aspect, the first hook extends out toward the outside of the opening of the box body and has a first hook portion protruding in the direction of movement of the movable assembly, the second hook extends out toward the inside of the opening of the box body and has a second hook portion protruding in the direction of movement of the movable assembly, and the first hook portion and the second hook portion are clamped. When the joint structure is including setting up the first trip on movable assembly and setting up the second trip on the protection casing, will realize first trip and the joint of second trip, there are multiple implementation, simultaneously for the motion mode of cooperation movable assembly, the tip that first trip stretches out towards the box body opening outside has first trip portion, the tip that the second trip stretches out towards the box body opening inboard has second trip portion, first trip portion and second trip portion are protruding along movable assembly direction of motion, guarantee that first trip portion and second trip portion can the joint, and after the movable assembly motion, can make first trip portion and second trip portion throw off. The arrangement of the first clamping hook part and the second clamping hook part can realize clamping, and the moving assembly has a limiting effect in the moving direction, so that the moving assembly can only unlock the clamping structure from the movement of one direction, and meanwhile, the limiting effect can utilize the elastic force of the first elastic piece to enable the clamping of the first clamping hook part and the second clamping hook part to be tighter. The scheme of this embodiment more matches the scheme of unilateral unblock.

In a fourteenth possible implementation manner of the first aspect, the first hook extends out toward the outside of the opening of the box body and has a third hook portion protruding in the direction perpendicular to the movement direction of the movable assembly, the second hook extends out toward the inside of the opening of the box body and has a fourth hook portion protruding in the direction perpendicular to the movement direction of the movable assembly, and the third hook portion and the fourth hook portion are clamped. Another kind of realization of first trip and second trip joint, the tip that first trip stretches out towards the box body opening outside has third trip portion, and the tip that the second trip stretches out towards the box body opening inboard has fourth trip portion, and third trip portion and fourth trip portion are all protruding along the direction of perpendicular to movable assembly motion. Compare the setting of first trip portion and second trip portion, third trip portion and fourth trip portion do not have spacingly in the direction along the motion of movable assembly, and then the movable assembly can be the motion of two relative directions and realize the unblock, match in the scheme of two side unblocks promptly more.

In a fifteenth possible implementation manner of the first aspect, the first hook and the second hook have guiding inclined surfaces, and when the protective cover rotates and covers the opening of the box body, the guiding inclined surfaces of the first hook and the second hook slide in a matching manner to guide the first hook and the second hook to be clamped. The guide inclined plane is arranged to facilitate the clamping connection of the first clamping hook and the second clamping hook when the protective cover is arranged at the opening of the box body.

In a sixteenth possible implementation manner of the first aspect, a resilient component is disposed on the protective cover, and when the protective cover is disposed at the opening of the box body, the resilient component is elastically deformed by being pressed and provides elastic restoring force. Divide fine box generally all to hang the wall installation, and divide the box body opening of fine box generally relatively lean on down, the safety cover that corresponds all leans on down the lock at the opening part of box body, promptly, under the normal condition, the safety cover receives the action of gravity, should keep the state at lock box body opening part. Like this, behind staff's unblock joint structure to when needing to operate at the opening part of box body, just need operate once more and open the safety cover, the safety cover is held to the one hand even, is unfavorable for very much that the staff operates. Consequently, set up the subassembly that kick-backs on the safety cover, after staff's unblock joint structure, the elastic restoring force of subassembly that kick-backs can drive and open the safety cover automatically, saves staff's manual step of opening the safety cover once more, and the elastic force of subassembly that just kick-backs can make the safety cover keep opening state, and the staff need not the one hand either hold up the safety cover, makes things convenient for the staff to carry out the operation such as relevant minute fibre more. Simultaneously, because the elastic deformation characteristic of resilience subassembly, when the safety cover lock when the opening part, the subassembly that kick-backs can also play a cushioning effect, absorbs the kinetic energy when the safety cover lock, avoids the part (for example joint structure etc.) between safety cover and the box body to be violently collided and damage.

In the seventeenth possible implementation of the first aspect, the resilient assembly includes a protrusion fixed on the inner side of the protection cover, and a sleeve sleeved on the protrusion, a second elastic member is disposed between the sleeve and the protrusion, and when the protection cover is disposed at the opening of the box body, the sleeve is squeezed, so that the second elastic member is elastically deformed. The implementation manner of the rebounding assembly may be various as long as the required elastic restoring force can be provided, for example, a component having elasticity (a spring, a plastic component having elasticity, etc.) is directly provided. In order to make the reliability of resilience subassembly higher, durable, and easy installation and realization have set up sleeve and projection cup jointed together, and set up the second elastic component between sleeve and the projection, the sleeve and the projection that cup joint like this are used for the direction slip, can produce axial relative displacement between each other, and the second elastic component is used for providing the elastic force, and then realizes the effect of resilience subassembly. Simultaneously, the sleeve can play a guard action to the second elastic component, prevents that the second elastic component from directly contacting with the box body and short circuit, stabbing the box body or wearing and tearing second elastic component scheduling problem that appears. And the sleeve is sleeved with the convex column, so that the protective cover is conveniently connected with the protective cover, and the installation is simpler.

In the eighteenth possible implementation of the first aspect, the radial direction of the protruding column is provided with a limiting protrusion, the sleeve is provided with a strip-shaped hole corresponding to the limiting protrusion, and when the sleeve is extruded, the limiting protrusion slides in the strip-shaped hole. Sleeve and projection cup joint, radially dodge by spacingly, but if circumference is not spacing, relative rotation probably takes place, if the axial is not spacing, can throw off each other, consequently, for circumference and the axial of being connected between spacing sleeve and the projection, the radial direction of projection is equipped with spacing arch, corresponds spacing arch on the sleeve and is equipped with the bar hole, when sleeve and projection take place axial displacement, spacing arch slides in the bar hole. Spacing arch and the cooperation in bar hole make the rotation that can spacing sleeve and projection circumference of the axial lateral wall of edge sleeve in bar hole, and the bar hole can spacing sleeve and the axial maximum displacement scope of projection along the lateral wall of circumference. Of course, the arrangement of the limiting protrusions and the strip-shaped holes is a more conventional choice, and the positions of the limiting protrusions and the strip-shaped holes can be interchanged on the basis, namely, the limiting protrusions can be arranged on the sleeve along the radial direction, and the strip-shaped holes can be arranged on the corresponding positions of the convex columns.

In a nineteenth possible implementation manner of the first aspect, the limiting protrusions are located on two opposite sides of the convex column, and the strip-shaped holes corresponding to the limiting protrusions are also arranged on two opposite sides of the sleeve. The quantity of spacing arch and projection can set up as required in a flexible way, and in order to guarantee that the atress of the sleeve and the projection that cup joint is even, the combination that spacing arch and projection one-to-one set up can set up the multiunit, and the position of multiunit evenly distributed in the circumferential direction. Certainly, for the convenience of production preparation, generally set up relative two sets of can, promptly, spacing protruding both sides that are located the projection relative, the bar hole corresponds spacing protruding also and sets up in the relative both sides of sleeve, like this, guarantees the spacing stable in structure between sleeve and the projection, and the atress is even.

In a twenty-first possible implementation manner of the first aspect, the number of the resilient assemblies is two, and the two resilient assemblies are respectively close to two sides of the protection cover. The resilience assembly is arranged on both sides of the protective cover, so that the two sides of the protective cover are stressed uniformly, the protective cover is not easy to deform, and the structure is more stable.

In a twenty-first possible implementation manner of the first aspect, the protection cover is rotatably connected to the opening of the box body through a rotating shaft, an arc-shaped chute is arranged on the box body, and the rotating shaft can slide in the arc-shaped chute. Like this, the safety cover is when opening, because the pivot of safety cover can slide in the arc spout, consequently, the safety cover not only revolutes the rotation of axes, still can remove along with the transform of pivot position, and then the opening that the safety cover can be opened is bigger to make things convenient for the staff to correspond the work in the opening part operation of box body.

In a twenty-second possible implementation manner of the first aspect, the number of the rotating shafts on the protection cover is two, the number of the arc chutes arranged on the box body is two, the centers of the two arc chutes coincide, the central angles corresponding to the two arc chutes are equal, the radius difference of the two arc chutes is equal to the distance between the two rotating shafts, and the two rotating shafts respectively extend into the two arc chutes in a matching manner. Two rotating shafts are arranged and correspond to each other in the arc-shaped sliding groove in a slidable mode, the circle centers of the two arc-shaped sliding grooves are overlapped, and the corresponding central angles are equal, so that when the protective cover rotates, the two rotating shafts slide in the respective arc-shaped sliding grooves. And the cooperation jointly of two pivot and arc spout can play spacing and damped effect, makes the safety cover can open under the enough big circumstances of opening, and its rotary motion can be in succession and slowly.

In a twenty-third possible implementation manner of the first aspect, the central angle corresponding to the two arc-shaped sliding grooves is 90 degrees. The central angle that two arc spouts correspond is 90 degrees, guarantees that the safety cover can carry out the upset of 90 degrees at least, exposes the opening of box body completely, makes things convenient for the staff to operate.

In a twenty-fourth possible implementation manner of the first aspect, the two sides of the opening of the box body are provided with supporting plates, each supporting plate is provided with two arc-shaped sliding grooves, the center of circle of each supporting plate, which is close to the arc-shaped sliding grooves, is provided with an avoidance notch, and when the protection cover is completely opened, one side edge of the protection cover extends into the avoidance notch. In order to conveniently place the protection cover on the box body conveniently after the protection cover is completely opened, a avoiding notch is formed in the supporting plate arranged on the box body and corresponds to the position, and the avoiding notch can enable one side edge of the protection cover to extend into the protection cover and plays a role in limiting the protection cover.

In a twenty-fifth possible implementation manner of the first aspect, an opening is formed in one side of the arc-shaped sliding groove closer to the circle center, and the rotating shaft in the arc-shaped sliding groove can slide out of the opening. The setting of two rotation axes and two arc spouts, the installation is not very convenient, for convenient installation, has the opening apart from dodging one side of the nearer arc spout of breach, and then, when the installation, this pivot can be followed the opening part and conveniently packed into in the corresponding arc spout.

In a twenty-sixth possible implementation manner of the first aspect, a position close to the end in the arc-shaped chute far away from the circle center has a limiting convex rib, and when the protective cover is completely opened, the rotating shaft far away from the circle center is limited at the end of the arc-shaped chute by the limiting convex rib. At the moment, the rotating shaft far away from the circle center cannot be displaced, if the protective cover moves, the protective cover can only rotate by taking the rotating shaft far away from the circle center as an axis, and when only one rotating shaft is taken as the axis, the distance between the two rotating shafts can be changed, so that the protective cover cannot be adapted to two arc-shaped sliding grooves with fixed distance, and therefore, the protective cover cannot move in the whole process. The position of the protective cover after being completely opened can be fixed through a simple limiting convex rib structure.

The embodiment of the present application provides an optical cable connection device, which may be a fiber distribution box (FAT), a Splicing and Splicing Closure (SSC), a Terminal Box (TB), or other boxes or boxes that can be applied to an Optical Distribution Network (ODN). The embodiment of the present application does not specially limit the specific form of the optical cable connection device.

For convenience of explanation, the following description will be given by taking the optical cable connecting apparatus as an optical fiber distribution box as an example.

In this case, referring to fig. 1, the fiber distribution box includes a housing 01, and a cover 02 is rotatably connected to the opening of the housing 01. The opening of the housing 01 can be covered by rotating the cover 02. When a plurality of optical cables need to be accessed, the cover 02 is opened, the optical cables extend into the opening of the shell 01 and are connected to corresponding positions, after the connection is completed, the cover 02 is rotated, the optical cable interface is protected, and meanwhile, the cover 02 is provided with a plurality of notches 021, and the optical cables can pass through the notches 021.

The optical cable connection device provided by the embodiment of the present application, with reference to fig. 3, 4 and 5, includes:

the box body 1 is provided with an opening, a movable component 2 is arranged in the box body 1 close to the opening, and the movable component 2 can move relative to the box body 1;

the protective cover 3 is rotatably connected with the opening of the box body 1, and a clamping structure 4 is arranged between the movable assembly 2 and the protective cover 3;

the protective cover 3 can be covered at the opening of the box body 1 when rotating relative to the box body 1, and the clamping structure 4 is used for fixing the relative positions of the box body 1 and the protective cover 3; when the operating movable assembly 2 moves relative to the box 1, the snap-in structure 4 is disengaged.

Referring to fig. 3, 4 and 5, due to the arrangement of the movable assembly 2, when the box body 1 and the protection cover 3 need to be opened, the movable assembly 2 can be operated to move relative to the box body 1, so that the clamping structure 4 between the box body 1 and the protection cover 3 is disengaged, and the protection cover 3 can be opened.

Certainly, when box body 1 and safety cover 3 joint are needed, also can be through controlling movable assembly 2 and for the motion of box body 1, make the joint department of each other of joint structure 4 between box body 1 and the safety cover 3 can avoid, treat that safety cover 3 further moves to the joint department of joint structure 4 and move to the position that can joint, make movable assembly 2 move for box body 1 again to make joint structure 4 joint.

Therefore, the movable assembly 2 can move relative to the box body 1 through operation, the box body 1 and the protective cover 3 can be unlocked and clamped, and compared with the scheme that external force is forcibly applied to the related technology, the structure at the clamping position is deformed to unlock, the structure at the clamping position cannot be greatly deformed, and the clamping structure 4 cannot easily reach the fatigue limit and cannot be easily damaged; on the other hand, because the unblock of joint structure 4 is realized through the motion of activity subassembly 2, and then can do the joint reliability of joint structure 4 higher, and when not worrying that joint department intensity is too high, the difficult deformation that takes place of material characteristic itself leads to the circumstances that can not the joint or can not unblock to take place.

The movable assembly 2 can be realized in various ways, and the effect of unlocking the clamping structure 4 can be realized as long as the position of the movable assembly can be changed. Taking the motion mode as an example, the motion mode of the movable assembly 2 may be sliding or rotating, and the like, in comparison, the rotating mode requires a larger motion space, and the sliding mode occupies a small space, is relatively easy to implement, and is convenient for the user to operate.

Therefore, referring to fig. 6, 7 and 8, based on the manner of the sliding movement, a specific movable assembly 2 may include a sliding rod 21 and a first elastic member 22, the sliding rod 21 extending in a direction parallel to the rotation axis of the protection cap 3, and the first elastic member 22 is brought into an elastically deformed state when the sliding rod 21 is operated to move relative to the case body 1.

Because when the slide bar 21 was operated and is slided, first elastic component 22 was in the elastic deformation state to provide the resilience force, then, can realize slide and the motion of replying of slide bar 21 for box body 1, can be applicable to the scheme that sliding motion can unblock joint structure 4.

The first elastic element 22 is in an elastically deformed state, which may be in an elastically compressed state, an elastically stretched state, or an elastically twisted state, and as long as the first elastic element 22 is in the elastically deformed state, its own structure and material characteristics may enable it to have an elastic force returning to the initial state, and when the external force is removed, the elastic force may push the sliding rod 21 to return to the initial state.

When the movable assembly 2 comprises the sliding rod 21 and the first elastic member 22, in order to realize the scheme that the clamping structure 4 is disengaged when the movable assembly 2 is operated to move relative to the box body 1, firstly, the sliding rod 21 is provided with an operable position so as to be convenient for a worker to operate.

Set up the structure that can supply the operation on slide bar 21, can be at the optional position of slide bar 21, for example, at the middle part or both ends etc. of slide bar 21, compare, the middle part of slide bar 21 is located box body 1 inside, and the staff is difficult for touching, and sets up the position of the both ends at slide bar 21 and realize more easily, and the action of the tip of operation slide bar 21 is for pressing the action, and the transmission of force is more high-efficient, realizes easily and makes things convenient for the staff to operate.

Therefore, an operable structure may be provided at both ends of the sliding rod 21, for example, referring to fig. 6 and 7, one end of the sliding rod 21 near the outer side of the box 1 is an operating end 211, and pressing the operating end 211 can move the sliding rod 21 relative to the box 1 to disengage the latch structure 4.

The operation end 211 of the sliding rod 21 can be exposed or hidden, and under the condition that the space on both sides of the installation position of the fiber distribution box is sufficient, in order to avoid the situation that a non-worker can unlock and open the optical cable connection device at will, as shown in fig. 6, in some embodiments, the operation end 211 of the sliding rod 21 is located in the box body 1, the position of the box body 1 corresponding to the operation end 211 of the sliding rod 21 is provided with an operation hole 11, and the shape of the operation hole 11 is matched with the outer contour of the unlocking tool.

Thus, the operation end 211 of the sliding rod 21 can be hidden, and the operation end 211 of the sliding rod 21 can be contacted only by extending a special tool of a worker into the operation hole 11, so that the unlocking operation of the clamping structure 4 can be carried out. Furthermore, only by means of a special tool, the clamping structure 4 can be unlocked and the fiber distribution box can be opened, and the situation that non-workers can unlock and open the optical cable connecting device at will is effectively avoided.

When the operation hole 11 is provided and the operation end 211 of the sliding rod 21 is hidden in the box body 1, a tool needs to be inserted into the operation hole 11 and touch the sliding rod 21 to open the fiber distribution box, and the outer contour of the tool needs to be matched with the inner contour of the operation hole 11 when the tool is inserted into the operation hole 11.

The shape of the inner contour of the handling hole 11 is provided with various realisations and the corresponding tools are also matched to the handling hole 11. For example, referring to fig. 9, the shape of the inner contour of the operation hole 11 may be circular; referring to fig. 10, the shape of the inner contour of the operation hole 11 may be a straight line; referring to fig. 11, the shape of the inner contour of the operation hole 11 may be a cross shape; alternatively, the shape of the inner contour of the operation hole 11 may be hexagonal or the like. Wherein, the round shape is more conventional, and the matched tool can be a rod-shaped tool with the diameter smaller than that of the operation hole 11; the tool corresponding to the straight line shape can be a straight screwdriver; the tool corresponding to the cross shape can be a cross screwdriver; the hexagonal counterpart tool may be a hex wrench.

Of course, the shape of the operation hole 11 and the corresponding tool are just some examples, the shape of the operation hole 11 may also be other special shapes, even irregular shaped holes, etc., and the tool corresponding to the operation hole 11 may also be a specially-made shape, and is not limited to a screwdriver or a wrench, etc. commonly used by a worker, for example, a matched special-shaped key tool, etc.

The fiber distribution box is generally installed in a building and outside a resident room, such as a corridor, the space in the corridor is complex, the installation position of the fiber distribution box may be open or narrow, and when the space on both sides of the installation position of the fiber distribution box is narrow, a tool (such as a screwdriver) may not have enough space to unlock the optical cable connection device.

Therefore, based on the requirement of space installation and unlocking, the operation end 211 of the sliding rod 21 can penetrate through the adaptive hole 12 of the box body 1 to extend out of the box body 1, and workers can conveniently operate and unlock the fiber distribution box by hands. Specifically, referring to fig. 12, the box body 1 is provided with an adapting hole 12 at a position corresponding to the operating end 211 of the sliding rod 21, and the operating end 211 of the sliding rod 21 passes through the adapting hole 12 and extends out of the box body 1.

In order to easily unlock the slide rod 21, the slide rod 21 only needs to be provided with one end as the operation end 211, and the other end is connected with the first elastic member 22, and the slide rod 21 is arranged on one side wall of the box body 1, so that the slide rod 21 can be unlocked.

Therefore, referring to fig. 7, in some embodiments, one end of the sliding rod 21 is an operating end 211, the other end of the sliding rod 21 has a receiving groove 212, one end of the first elastic member 22 is located in the receiving groove 212, and referring to fig. 6 again, the other end of the first elastic member 22 abuts against the inner side of the box body 1. Namely, the one-sided unlocking is realized, the structure is simple, and the realization is easy.

As mentioned above, there is a great uncertainty about the space around the fiber distribution box after installation, and the operating end 211 of the slide lever 21 is provided at a different position and an unlockable position for different installation positions. For example, if the fiber distribution box is installed with at least two side walls close to each other, in this case, if the operation end 211 of the optical cable connection device is unlocked on one side, the unlocked position is likely to be blocked, resulting in a failure to unlock the fiber distribution box. Or two different single-side unlocking fiber distribution boxes are required to be arranged so as to be suitable for the situations of different space positions. This has just increased manufacturing cost again, and the staff need carry two kinds of branch fine boxes of different specifications in advance, and the construction is very inconvenient.

From this, can all be close to the outside of box body 1 with the both ends of slide bar 21, and be operation end 211, and the both ends of slide bar 21 have all cup jointed first elastic component 22, and is concrete, refer to fig. 13, in some embodiments, the both ends of slide bar 21 all are close to the outside of box body 1, and are operation end 211, refer to fig. 14, the outside at the both ends of slide bar 21 all has circumference limit step 213, and first elastic component 22 is two, cup joints the outside at the both ends of slide bar 21 respectively and supports and lean on in circumference limit step 213 department. Therefore, the two sides of the fiber distribution box can be unlocked, namely, the two sides are unlocked, and the problem that one side of the fiber distribution box is blocked and cannot be unlocked is solved.

The sliding rod 21 is a rod-shaped structure, and the sliding rod 21 may be manufactured separately and then assembled in order to facilitate assembly of the rod-shaped structure, and for example, referring to fig. 7, the sliding rod 21 includes a first portion 214 and a second portion 215, and the first portion 214 and the second portion 215 may be connected by a protrusion 216 and a recess 217.

Referring to fig. 7, the sliding rod 21 may have a hollow structure in order to save materials and reduce costs.

Meanwhile, in order to secure the strength of the slide bar 21 having a hollow structure, referring to fig. 7, a plurality of ribs 218 are provided in a hollow space inside the slide bar 21.

Because divide fine box to be the equipment with optical fiber signal distribution, the interface of its wiring often has a lot, arranges the opening part at box body 1 often, and when dividing fine box cover, need reserve the position of dodging of the kneck wiring, like this, there is the risk of being pulled out by the mistake at the kneck of optic fibre cable.

Meanwhile, according to the characteristics of the optical fiber cable and the conventional interface, after the optical fiber cable is plugged into the corresponding interface, the optical fiber cable cannot be pulled out as long as the outside of the connector of the optical fiber cable cannot be pinched by a hand.

Therefore, in order to prevent the optical fiber cable from being unplugged and plugged by non-working personnel, referring to fig. 3, in some embodiments, a plurality of optical fiber adapters 5 are arranged at the opening of the box body 1, referring to fig. 15 again, the optical fiber adapters 5 are used for plugging the optical cable connectors 6, two sides of the protective cover 3 corresponding to each optical cable connector 6 are provided with baffles 31, and the coverage of the projection of the baffles 31 towards the optical cable connectors 6 is greater than or equal to that of the optical cable connectors 6.

Like this, when the optical cable is pegged graft in optical fiber adapter 5, baffle 31 keeps off in the both sides of optical cable connector 6, and then makes when not opening safety cover 3, and the unable lateral wall that contacts optical cable connector 6 of people's finger, and then can not pull out the optical cable of inserting at will.

The movable assembly 2 moves in the box body 1, and a limiting structure is inevitably required to be arranged around the space in the box body 1 correspondingly moving so as to ensure that the movable assembly 2 moves according to a preset track. And set up limit structure in box body 1 can have multiple implementation, for example set up the hole that can pass when activity subassembly 2 moves, perhaps set up attached gliding limiting plate etc. when activity subassembly 2 moves, simultaneously, these structures can be set up specially, also can utilize the original structure in the box body 1.

As mentioned above, a plurality of fiber optic adapters 5 may be arranged at the opening of the box body 1, and a space for the movable assembly 2 to move is formed between the combined structure of the arranged fiber optic adapters 5 and the inner wall (including the bottom surface) of the box body 1. Furthermore, referring to fig. 5, when a plurality of optical fiber adapters 5 are arranged at the opening of the box body 1, the movable assembly 2 can be arranged between the optical fiber adapters 5 and the bottom surface of the box body 1, so that the internal space of the box body 1 is fully utilized, the structure is more reasonable, the realization is easy, and the design and production cost is saved.

The clamping structure 4 arranged between the movable assembly 2 and the protective cover 3 can be realized in various ways, for example, in a way of clamping two clamping hooks, a way of clamping the clamping hooks and the clamping grooves, or a way of clamping the clamping hooks and the clamping holes, and the like. Referring to fig. 16 and 17, for implementing the two-buckle clamping, the clamping structure 4 includes a first hook 41 disposed on the movable assembly 2 and a second hook 42 disposed on the protection cover 3, and the first hook 41 and the second hook 42 are clamped with each other to fix the relative positions of the box body 1 and the protection cover 3.

Referring to fig. 16 and 17, the second hook 42 may be a groove structure, the first hook 41 is clamped into the groove structure, and the sidewall of the groove structure may limit the relative position of the first hook 41, so that the clamped connection is more reliable.

It should be noted that, referring to fig. 8 and 16, when the movable assembly 2 includes the slide lever 21, since the slide lever 21 is a direct moving member, the first hook 41 may be directly provided on the slide lever 21.

When the engaging structure 4 includes the first engaging hook 41 disposed on the movable assembly 2 and the second engaging hook 42 disposed on the protective cover 3, there are various ways to engage the first engaging hook 41 and the second engaging hook 42, for example, in some embodiments, referring to fig. 16 and 17, the first engaging hook 41 extends toward the outside of the opening of the case 1 and has a first engaging hook portion 411 protruding in the moving direction of the movable assembly 2, and the second engaging hook 42 extends toward the inside of the opening of the case 1 and has a second engaging hook portion 421 protruding in the moving direction of the movable assembly 2, and the first engaging hook portion 411 and the second engaging hook portion 421 engage with each other.

First trip portion 411 and second trip portion 421 are protruding along movable assembly 2 direction of motion, can cooperate movable assembly 2's motion mode, guarantee that first trip portion 411 and second trip portion 421 can the joint, and movable assembly 2 moves the back, can make first trip portion 411 and second trip portion 421 throw off.

It should be noted that, referring to fig. 16 and fig. 17, in the above embodiment, the first hook portion 411 and the second hook portion 421 are configured to be clamped, and have a limiting effect in the moving direction of the movable assembly 2, so that the movable assembly 2 can only unlock the clamping structure 4 from the movement in one direction, and meanwhile, the limiting effect can make the clamping of the first hook portion 411 and the second hook portion 421 closer by using the elastic force of the first elastic element 22. The scheme of this embodiment more matches the scheme of unilateral unblock.

Referring to fig. 18 and 19, the first hook 41 extends out towards the outside of the opening of the box 1 and has a third hook portion 412 protruding in the direction perpendicular to the movement direction of the movable assembly 2, the second hook 42 extends out towards the inside of the opening of the box 1 and has a fourth hook portion 422 protruding in the direction perpendicular to the movement direction of the movable assembly 2, and the third hook portion 412 and the fourth hook portion 422 are engaged with each other.

Compared with the arrangement of the first hook part 411 and the second hook part 421, the third hook part 412 and the fourth hook part 422 are not limited in the direction of the movement of the movable assembly 2, and the movable assembly 2 can be unlocked by the movement of two opposite directions, namely, the scheme of unlocking at two sides is matched more.

In order to facilitate the engagement between the first hook 41 and the second hook 42 when the protection cover 3 is covered at the opening of the box body 1, referring to fig. 18 and 19, the first hook 41 and the second hook 42 both have a guiding inclined surface 43, and when the protection cover 3 is rotated and covered at the opening of the box body 1, the guiding inclined surfaces 43 of the first hook 41 and the second hook 42 slide in a matching manner to guide the engagement between the first hook 41 and the second hook 42.

For the two implementation manners of the first hook 41 and the second hook 42, the principle of the arrangement of the guiding inclined plane 43 is the same, specifically, the guiding inclined plane 43 may be arranged on the first hook portion 411 of the first hook 41 and the second hook portion 421 of the second hook 42; referring to fig. 18 and 19, the third hook portion 412 of the first hook 41 and the fourth hook portion 422 of the second hook 42 may be provided with the guide slope 43.

Divide fine box generally all to hang the wall installation, and divide 1 opening of box body of fine box generally relatively lean on down, the safety cover 3 that corresponds all generally leans on down the lock at the opening part of box body 1, promptly, under the normal condition, safety cover 3 receives the action of gravity, should keep the state at 1 opening part of lock box body. Like this, behind staff's unblock joint structure 4 to when needing to operate at the opening part of box body 1, just need operate once more and open safety cover 3, the single hand holds safety cover 3 even, is unfavorable for very much that the staff operates.

Therefore, in order to facilitate the operation of the worker, referring to fig. 20 and 21, the resilient member 7 is provided on the protective cover 3, and referring to fig. 22, when the protective cover 3 is covered on the opening of the case 1, the resilient member 7 is pressed to be elastically deformed and provide an elastic restoring force.

Set up resilience subassembly 7 on protective cover 3, behind staff's unblock joint structure 4, resilience force of resilience subassembly 7 can drive and open protective cover 3 automatically, saves the staff and opens protective cover 3 step manually once more, and resilience subassembly 7's elastic force can make protective cover 3 keep opening the state, and the staff also need not but hold protective cover 3, makes things convenient for the staff to carry out operations such as relevant minute fibre more.

Simultaneously, because the elastic deformation characteristic of resilience subassembly 7, when the safety cover 3 lock when the opening part, resilience subassembly 7 can also play a cushioning effect, absorbs the kinetic energy when the safety cover 3 lock, avoids the part (for example joint structure 4 etc.) between safety cover 3 and the box body 1 to be violently collided and damaged.

The rebound assembly 7 can be realized in various manners as long as the required elastic restoring force can be provided, for example, a member having elasticity (a spring, a plastic member having elasticity, etc.) is directly provided.

In order to make the rebound assembly 7 have higher reliability, durability and easy installation and implementation, referring to fig. 23, 24 and 25, the rebound assembly 7 includes a boss 71 fixed inside the protection cover 3 and a sleeve 72 sleeved on the boss 71, a second elastic member 73 is arranged between the sleeve 72 and the boss 71, and when the protection cover 3 covers the opening of the box body 1, the sleeve 72 is pressed to make the second elastic member 73 elastically deformed.

Due to the fact that the sleeve 72 and the convex column 71 are sleeved together and the second elastic piece 73 is arranged between the sleeve 72 and the convex column 71, the sleeve 72 and the convex column 71 which are sleeved together are used for guiding to slide, axial relative displacement can be generated between the sleeve 72 and the convex column 71, the second elastic piece 73 is used for providing elastic force, and then the effect of the rebound assembly 7 is achieved.

Meanwhile, the sleeve 72 can protect the second elastic member 73, thereby preventing the second elastic member 73 from being directly contacted with the case body 1 to cause short circuit, stabbing the case body 1, or wearing the second elastic member 73. And the sleeve 72 is sleeved with the convex column 71, so that the protective cover 3 is conveniently connected, and the installation is simpler.

The sleeve 72 and the convex column 71 are sleeved, radial avoidance is achieved and limited, however, if the circumferential direction is not limited, relative rotation can occur, and if the axial direction is not limited, relative separation can occur, therefore, for the circumferential direction and the axial direction of connection between the limiting sleeve 72 and the convex column 71, referring to fig. 23, 24 and 25, a limiting protrusion 711 is arranged in the radial direction of the convex column 71, a strip-shaped hole 721 is arranged on the sleeve 72 corresponding to the limiting protrusion 711, and when the sleeve 72 is extruded, the limiting protrusion 711 slides in the strip-shaped hole 721.

Furthermore, the protruding column 71 is provided with a limiting protrusion 711 in the radial direction, the sleeve 72 is provided with a strip-shaped hole 721 corresponding to the limiting protrusion 711, and when the sleeve 72 and the protruding column 71 are displaced axially, the limiting protrusion 711 slides in the strip-shaped hole 721. Through the cooperation of spacing arch 711 and bar hole 721, make bar hole 721 along the axial lateral wall of sleeve 72 can spacing sleeve 72 and projection 71 circumference rotatory, and bar hole 721 can spacing sleeve 72 and projection 71 axial maximum displacement scope along the lateral wall of circumference.

Of course, the arrangement of the limiting protrusion 711 and the strip-shaped hole 721 is a relatively conventional choice, and on this basis, the positions of the limiting protrusion 711 and the strip-shaped hole 721 can also be interchanged, that is, the limiting protrusion 711 can be arranged on the sleeve 72 along the radial direction, and the strip-shaped hole 721 can be arranged on the corresponding position of the convex column 71.

The number of the limiting protrusions 711 and the convex columns 71 can be flexibly arranged as required, in order to ensure that the sleeve 72 and the convex columns 71 which are sleeved are evenly stressed, the combination of the one-to-one corresponding arrangement of the limiting protrusions 711 and the convex columns 71 can be provided with a plurality of groups, and the positions of the plurality of groups are evenly distributed in the circumferential direction.

On this basis, of course, for convenience of manufacturing, two sets of the limiting protrusions 711 are disposed on two opposite sides of the protruding pillar 71, and the strip-shaped holes 721 corresponding to the limiting protrusions 711 are also disposed on two opposite sides of the sleeve 72, as shown in fig. 23, 24, and 25. The limiting protrusions 711 are located on two opposite sides of the protruding column 71, and the strip-shaped holes 721 corresponding to the limiting protrusions 711 are also arranged on two opposite sides of the sleeve 72, so that the limiting structure between the sleeve 72 and the protruding column 71 is stable, and stress is uniform.

It should be noted that, after the rebound assembly 7 is disposed, in the actual production installation and operation process, it is found that the rebound assembly 7 may interfere with the sliding rod 21 of the movable assembly 2, and therefore, referring to fig. 7 and 8, an avoidance step 219 is correspondingly disposed on the sliding rod 21, and the avoidance step 219 can avoid the pre-contact position of the rebound assembly 7, so as to prevent the two movable components (the movable assembly 2 and the rebound assembly 7) from interfering with each other and affecting the operation of the mechanism.

In order to make the two sides of the protection cover 3 uniformly stressed and make the protection cover 3 not easily deformed, and the structure is more stable, referring to fig. 20, 21 and 22, two rebound assemblies 7 are provided and are respectively close to the two sides of the protection cover 3.

In some embodiments, referring to fig. 4, the protecting cover 3 is rotatably connected to the opening of the box body 1 through a rotating shaft 32, the box body 1 is provided with an arc-shaped sliding slot 13, and the rotating shaft 32 can slide in the arc-shaped sliding slot 13. Like this, safety cover 3 is when opening, because the pivot 32 of safety cover 3 can slide in arc spout 13, consequently, safety cover 3 not only revolutes pivot 32 and rotates, still can remove along with the transform of pivot 32 position, and then the opening that safety cover 3 can open is bigger to make things convenient for the staff to correspond the work in the opening part operation of box body 1.
