Abstract

The utility model discloses a novel fiber-optic cabinet comprising a cabinet, which has two fiber-optic cable outlets on the body. The cabinet comprises an upper cover, a lower cover and a fiber-bound rotating shaft is provided between the upper cover and the lower cover and the fiber-bound rotating shaft is provided with a handle. The utility model features in simple structure and does not need to secure the fiber cables through structural components. The device is very convenient to dismantle the fiber cables in locations that do not need fiber-optic cabinets; meanwhile, if the fiber cable is a need, the device is very convenient to mount the fiber cables for use. When the fiber cables are mounted, there is no need to disconnect the cable ports of the two sides of the fiber cables that connect with the equipment. Therefore, the fiber-optic cabinet for the equipment fiber cables that are already online is also possible to use. The device solves the various problems that during the process of actual fiber cable applications, the lengths of the fiber cables fail to meet the actual needs. The unique structure of the device enables the user to conveniently adjust the lengths of the cable in the process of using; meanwhile, as the inexpensive plastic products can be used for the material of the utility model, the device has low cost.

Description

The novel optical fiber box

Technical field

The utility model relates to fiber management, the memory device in the communication field, relates in particular to a kind of fiber termination box.

Background technology

In the optical communication field, the use of optical fiber is indispensable.But in daily use; the short distance occasion in machine room or producing the debug phase particularly; owing to order and use long optical fiber when the fiber lengths of making is improper to cause wiring; if messy putting in machine room; because optical fiber is to the strictness restriction of the radius of minimum bend; cause optical power attenuation excessive through regular meeting, the influence debugging has also influenced the attractive in appearance of machine room simultaneously.Some present fiber termination boxs only have the function of storing fiber optic, and are powerless for the inappropriate situation of length of optical fiber customization in the use of reality; And the management devices that some optical fiber are arranged also has the winding processing capacity to surplus fibre, but or be bigger rack, be used for the place that machine room has a large amount of optical fiber to pass in and out more.

The utility model content

Problem to be solved in the utility model provides a kind of simple in structure, with low cost, can extract, regain the fiber termination box of storage administration easily as required out to optical fiber.

The technical scheme that the utility model adopted is: the novel optical fiber box, comprise box body, described box body is provided with two optical fiber fiber mouths, and described box body comprises upper cover plate, lower cover, be provided with between described upper cover plate, the lower cover around fine rotating shaft, describedly be provided with handle around fine rotating shaft.

The preferred ovalize of box body, two optical fiber fiber mouths are located at two vertex positions of major axis.

Be provided with optical fiber duct around fine rotating shaft, the optical fiber duct width just in time can hold an optical fiber, and optical fiber duct is preferably S-shaped, and bending radius is greater than 3.15 centimetres.

In fine rotating shaft, also be provided with rotation lock device, make fiber termination box that following two states is in use arranged like this: 1, stationary state at ordinary times, in such cases, handle is fixed and can not rotates, what this moment and its were fixed together also is fixed around fine rotating shaft, so the length of optical fiber is fixed in such cases, can not regulate; 2, the scalable state when the length of optical fiber need be regulated, in such cases, handle can freely rotate, when the oversize needs of the length of optical fiber shorten, turning handle drives around fine rotating shaft and twines optical fiber, when needing longer optical fiber, can extract optical fiber out on the contrary.

Being provided with rotation lock device around fine rotating shaft can be following two kinds of optimal ways: 1, the relevant position is provided with at least one pilot hole on register pin that is being provided with on the handle and the box body, when the needs location, when making optical fiber keep certain-length, press register pin, register pin inserts the pilot hole on the box body, the rotating shaft that be connected on the handle this moment is fixed and can't rotates, the length of optical fiber also is fixed, when needs change fiber lengths, extract register pin, just turning handle has been operated freely; 2, handle the preceding paragraph is made as tetragonal body and correspondingly be provided with the square hole that size matches at box body, in fine rotating shaft, in the time of the needs turning handle, handle is outwards extracted a bit.Snap in this moment is tetragonal body on the handle around fine rotating shaft, and the arm pivot post of contact box body all is a right cylinder, therefore turning handle the time, carrying out around fibre in the middle of handle can drive around fine rotating shaft, the length of optical fiber can be regulated this moment, in the time of the needs fixed handle, handle inwardly is pressed into, this moment, the tetragonal body in the middle of the handle snapped in simultaneously around fine rotating shaft and box body, at this time handle, all fixed around fine rotating shaft by box body, therefore the fiber lengths that is wrapped in fine rotating shaft also is fixed.

The beneficial effects of the utility model are: the utility model is simple in structure, do not need optical fiber to be fixed by structural member, can dismantle optical fiber very easily in the place that does not need fiber termination box, simultaneously can load onto optical fiber very easily in needs uses, be connected the optical fiber interface on the equipment on the both sides that dress does not need to disconnect optical fiber optical fiber the time, so for also using this fiber termination box at the apparatus optical fiber of netting, having solved in reality uses the fiber lengths that customizes in the process of optical fiber can not satisfy the variety of problems that actual needs brings, its particular structure can make the user in use can regulate fiber lengths at any time easily, simultaneously because the utility model is simple in structure, material can be selected very cheap plastic products, cost is very low, the memory storage that can use this fiber termination box to dispatch from the factory as optical fiber is so increased its usable range more.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the contour structures synoptic diagram of the utility model specific embodiment, as shown in Figure 1, fiber termination box comprises the box body of an ovalize, is provided with two optical fiber fiber mouths 1 (one of them is covered can't see) on two major axis summits of ellipse, is provided with a handle 2 above the box body of fiber termination box.

Figure 2 shows that the decomposition texture synoptic diagram of the utility model specific embodiment, as shown in the figure, box body comprises upper cover plate 3, lower cover 4, is clipped between upper cover plate 3, the lower cover 4 around fine rotating shaft 5.

Fig. 3 is the inner structure synoptic diagram of the utility model specific embodiment, and as shown in the figure, the optical fiber duct in fine rotating shaft 5 is S-shaped, and 1＞3.15 centimetre of its radius of curvature R meets the bending radius of optical fiber, and its width just in time can hold an optical fiber.
