Description

Optical fiber box supporting cutting-free and connecting-free box body replacement

Technical Field

The present disclosure relates to the field of data communication technologies, and more particularly, to an optical fiber box supporting a splice-free replacement box.

Background

A cable distribution box (cable cross-connect box) is a cross-connect device for connecting a trunk cable and a distribution cable. The wire inlet hole of the optical fiber distribution box (optical cross-connecting box) in the prior art is a closed wire inlet hole, and refer to fig. 1 and 2 specifically. Fig. 1 and 2 illustrate an example of a wall-mounted fiber optic enclosure of the prior art, wherein the wall-mounted fiber optic enclosure includes an openable enclosure 1, the enclosure 1 containing optical distribution equipment, a trunk cable entering the enclosure 1 from an open-hole entrance hole in the bottom of the optical distribution enclosure and entering the optical distribution equipment, and a distribution cable exiting the optical distribution equipment and exiting the enclosure 1 from the open-hole entrance hole. The cable 2 (including the incoming trunk cable and the outgoing distribution cable) is fixed to the wall outside the cabinet by means of staples 3 or the like, the staples 3 being, for example, plastic staples or metal staples or the like.

When the box body needs to be replaced for maintenance, capacity expansion and the like, because the access mode of the optical cables in the optical fiber box in the prior art is a closed open hole mode, the traditional solution is that the old optical fiber box needs to be replaced by an optical cable cutting and connecting method. This requires breaking the old cabinet, cutting the cable, and threading the cable into a new cabinet and re-splicing the cables. The mode of changing the box body brings a large amount of cutting and connecting work, and communication services of customers need to be interrupted, so that a large amount of manpower is needed, the construction time is long, and the efficiency is low. Further, since the old box needs to be destroyed, the replaced box cannot be reused, resulting in waste of equipment such as boxes.

SUMMERY OF THE UTILITY MODEL

To overcome at least one of the above-mentioned drawbacks of the prior art, it is an object of the present disclosure to provide an optical fiber box supporting a splice-free replacement of a box body, thereby achieving flexible replacement of the box body without performing optical cable splice, and completing replacement of the box body without damaging the box body. It is desirable that the fiber box have at least one of advantages of simple structure, easy operation, high work efficiency, low labor and material costs, and the like.

To achieve the above object, the present disclosure provides an optical fiber box, including: a case including a sidewall defining a front opening, the sidewall having a slot disposed thereon, the slot extending to the opening; and a latch cooperating with the slot to define a cable access aperture in the side wall.

Compared with the prior art, the original closed type wire inlet hole is changed into the groove, and the clamping piece is arranged on the groove and matched with the groove, so that a space for accommodating the optical cable is formed. The improvement of the closed wire inlet hole has the following advantages: when the box body is replaced, the optical cable can be separated from the old box body only by detaching the clamping piece; when a new box body is replaced, the new box body can be replaced only by fixing the optical cable into the groove of the new box body, so that the new box body is not required to be cut again, the old box body is not damaged, and the box body is kept complete while cutting work is omitted.

Other features of the present disclosure and advantages thereof will become more apparent from the following detailed description of exemplary embodiments thereof, which proceeds with reference to the accompanying drawings.

FIG. 3 illustrates an exemplary embodiment of a fiber optic cabinet supporting a splice-free replacement cabinet. Wherein the fiber box has a box body 1. The housing 1 comprises side walls 4 defining a front opening of the housing. Alternatively, the cabinet 1 may have a door on the front for closing the front opening. The door is shown in the open state in fig. 3. Optical devices including a spectroscopic device, a fusion splicing device, and the like can be accommodated in the case 1. In practical applications, the fiber box may be a cable cross-connecting box, a distribution box, a fiber distribution box, or the like. The shape of the box is generally cubic, but in some embodiments may be cylindrical or other shape that accommodates the application scenario. The material for manufacturing the case 1 may include metal (such as iron), resin, inorganic non-metallic material (such as glass fiber), organic polymer material, and the like.

A slot 5 is provided in a side wall 4 of the housing 1 for receiving the optical fibre cable 2 into and out of the housing 1. The slot 5 may extend on the side wall 4 as far as the front face of the tank 1 is open. Preferably, the groove 5 may be provided at the bottom of the case 1, as shown in fig. 3. Of course, the slot 5 may also be provided in other parts of the tank.

In embodiments of the present disclosure, cables 2 entering the enclosure 1 and cables 2 exiting the enclosure 1 may be respectively disposed in different troughs 5. The side wall 4 is preferably provided with two or more grooves 5. For example, as shown in fig. 3, the side wall 4 may be provided with two slots 5, wherein one slot 5 is used for accommodating the optical cable 2 entering the enclosure 1 and the other slot 5 is used for accommodating the optical cable 2 leaving the enclosure 1. The number of slots 5 may also be greater than two, for example the number of slots 5 may be equal to the sum of the number of cables 2 entering and leaving the cabinet 1. Specifically, for an N in M out fiber box, (N + M) slots 5 may be provided in the side wall 4. Of course, for an N in M out fiber box, the side wall 4 may also be provided with less than (N + M) grooves 5. The optical cables entering the box body and leaving the box body are arranged in different grooves, so that clear routing can be realized, and maintenance and the like are facilitated.

In embodiments of the present disclosure, the slot 5 may be a U-shaped slot, such as the slot 5 shown in fig. 3. Such a design is intended to match a cable 2 of generally circular cross-section, thereby reducing friction between the groove and the cable disposed therein, facilitating securing of the cable 2 in the groove, and facilitating processing.

In the embodiment of the present disclosure, the position of the groove 5, the size of the groove 5, and the like on the housing 1 may be designed according to the size of the optical fiber box. For example, in the case where the fiber box has dimensions of 700 mm long × 520 mm wide × 290 mm deep, two U-shaped grooves may be provided in the bottom of the box, each being 50 mm to the left or right from the horizontal centerline of the box in the horizontal direction, both being 200 mm long × 30 mm wide × 11 mm high.

The fibre optic cabinet further comprises a clip 6, the clip 6 being cooperable with the slot 5 to define a space on the side wall 4 in which the optical fibre cable 2 can be received. The clip 6 also serves to secure the optical cable 2, for example, when the slot 5 is provided on the bottom of the cabinet 1.

In the embodiment of the present disclosure, the card member 6 is preferably detachable.

In the disclosed embodiment, the length of the escapement 6 preferably does not exceed the length of the slot 5. If the length of the card member 6 exceeds the length of the slot 5, the fitting of the card member 6 with the slot 5 is not facilitated, and the waste of the card member 6 is also caused.

In embodiments of the present disclosure, the catch 6 may mate with the slot 5 in a variety of ways. For example, the catch 6 may be fixed to the slot 5 in a snap-fit manner, wherein the catch 6 may be a snap-fit made of a material with a certain flexibility, such as plastic or metal. For example, the dog 6 may be of the fixed nut type. For example, the catch 6 may be spring loaded.

In embodiments of the present disclosure, the clip 6 may include a variety of configurations. For example, a length of cable 2 may be secured together in the slot 5 by a plurality of identical clips 6. For example, only one strip-like clamping element 6 may be required to secure a length of cable 2 in the slot 5.

In the embodiment of the present disclosure, the clip 6 may be configured to be unable to slide relative to the slot 5 once fixed into the slot 5 into engagement with the slot 5, thereby achieving accurate and reliable fixing of the optical cable 2 to the cabinet 1.

In an embodiment of the present disclosure, the clip 6 may also be configured to slide relative to the slot 5 after being fixed in the slot 5 to form a fit with the slot 5, i.e. to slide with the slot 5 as a track. By enabling the slidable clip 6 to slide in the slot 5, the position of the space on the side wall 4 defined by the cooperation of the slot 5 with the clip 6 can be changed, thereby changing the position on the cabinet 1 to which the optical cable 2 is fixed. This arrangement allows for variable fixing of the position of the optical cable 2 entering or leaving the fiber box, and thus allows for more flexible use in practical engineering.

Preferably, at least one of the end of the slot 5 remote from the front opening of the housing and the end of the clip 6 remote from the front opening of the housing is shaped to match the outer shape of the optical cable. For example, since the cross-section of the cable is generally circular, the slot 5 may preferably be a U-shaped slot in order to match the profile of the cable. Further alternatively, the end of the clip member 6 remote from the opening of the housing 1 may also be U-shaped, as shown in particular in fig. 4.

Preferably, in order to enable cables to enter and exit the housing 1, the fibre optic housing is also provided with cable access holes 7 through which cables 2 enter and exit the space defined by the cooperation of the clips 6 with the slots 5 on the side walls 4. In prior art fiber optic enclosures, cable access holes are typically provided in the enclosure and are enclosed. Thus, when replacing the fiber optic cabinet, the cable access holes need to be broken to remove the cables.

In embodiments of the present disclosure, cable access holes 7 may be provided at the ends of the slots 5 remote from the opening, as shown in particular in fig. 4. The space defined by the matching of the clamping piece 6 and the groove 5 is the optical cable access hole 7. In this exemplary embodiment, preferably, at least one of the end of the groove 5 remote from the opening of the housing 1 and the end of the card 6 remote from the opening of the housing 1 may be shaped to match the outer shape of the optical cable 2. For example, as shown in fig. 3, the shape of the groove 5 may be designed to be U-shaped so as to match the optical cable 2, which is generally circular in cross-section. For example, as shown in fig. 4, the end of the clamp 6 remote from the opening of the cabinet 1 may be provided in a U-shape so as to match the optical cable 2, which is generally circular in cross-section.

In embodiments of the present disclosure, cable access holes 7 may also be provided on the clip member 6, as shown in particular in fig. 5. Preferably, the clip 6 shown in fig. 5 may also be configured to be slidably securable relative to the slot 5 when secured in the slot 5 in forming engagement with the slot 5, so that the position of the cable access aperture 7 may be varied accordingly by sliding the clip 6 in the slot 5. This arrangement allows for variable fixing of the position of the optical cable 2 entering or leaving the fiber box, and thus allows for more flexible use in practical engineering. The clip member 6 may be formed integrally or may be formed by combining two or more members. For example, in fig. 5, the card member 6 may be formed by combining two members of the left and right. The two components are assembled together and fitted to the channel 5 to form the cable access aperture 7. In some embodiments, the clip 6 may include a plurality of cable access holes 7 for securing a plurality of cables 2 in the channel 5.

It is worth noting that the configurations shown in fig. 4 and 5, respectively, are not mutually exclusive. In some embodiments, the two may be combined.

Preferably, a removable card module may be further mounted at the cable access aperture 7 for further securing the cable in the vicinity of the cable access aperture 7. In this exemplary embodiment, preferably, the detachable card member module may be fixed to the housing 1, the slot 5 and/or the card member 6 using a screw, or may be fixed to the housing 1, the slot 5 and/or the card member 6 by means of a snap, or the like. In this exemplary embodiment, the removable cartridge module may include a variety of configurations. For example, the removable cartridge module may be integrally formed with the cartridge 6. For example, in the case where the card member 6 for cooperating with the slot 5 is a plurality of identical card members, the removable card member module may also be the same member as the card member 6. For example, the removable cartridge module may be a separate component from the cartridge 6. When the optical cable 2 is replaced, the detachable card module needs to be detached from the box 1 before the optical cable 2 is detached, so that the optical cable 2 can be detached from the box 1.

To sum up, this disclosure provides an optical fiber box, includes: a box body comprising a side wall for defining a front opening, the side wall having a slot disposed thereon, the slot extending to the opening; and a latch cooperating with the slot to define a cable access aperture in the side wall.

In one embodiment, the cartridge is removable.

In one embodiment, a detachable card module is further installed at the optical cable access hole, and the detachable card module is used for fixing the optical cable at the optical cable access hole.

For the optical fiber box in the disclosure, when the box body needs to be replaced, only the clamping piece on the groove needs to be detached, the optical cable and the optical equipment (such as light splitting equipment, welding equipment and the like) related to the optical cable in the box body are integrally taken out from the original box body through the front opening, the optical cable and the optical equipment related to the optical cable are moved into a new box body together, the optical cable is placed in the groove of the new box body, and then the clamping piece is installed, so that the process of replacing the box body can be completed. Therefore, when the box body is replaced, the box body does not need to be damaged, and the cutting work does not need to be carried out, so that the cyclic utilization of the box body is realized, the communication service is prevented from being interrupted, and the working efficiency and the quality are improved.

The present disclosure also has at least one of the following advantages: the multi-channel routing design is that the routing channel of the main optical cable is separated from the routing channel of the distribution optical cable, so that the routing route is clear, and the standardized construction and maintenance are facilitated; flexible optical cable fixing, wherein the drawn optical cable is fixed in a space between the detachable clamping piece and the wire inlet groove at the bottom of the box body, and the clamping piece can be detached to take down the optical cable when needed; the box body can be flexibly replaced under the conditions of not cutting and connecting and not interrupting communication, and the replaced box body can be repeatedly recycled; the operation of replacing the box body is simplified, the working efficiency is improved, the labor cost and the material cost are reduced, and the social benefit is good.

Therefore, the innovation of the utility model can realize the flexible separation of the optical cable and the box body which enter and exit the box body, only the box body needs to be replaced without damaging the box body and cutting in the cutting process, and finally the purpose of replacing the box body without cutting is achieved.
