Technical field

Communication equipment field is the utility model is related to, more specifically, it relates to a kind of point fibre for reducing optical fiber abrasion Case.

Background technology

With passive optical-fiber network technology maturation application, new business fast development including IP videos and cloud computing with And society increases the continuous of the high broadband services demand such as high definition Interactive Internet TV and video monitoring, leads in progress, people Letter industry has recognized that fiber to the floor particularly Fiber-To-The-Node is difficult to meet the needs of business long-run development, optical access network New upgrade requirement is all suffered from bandwidth, service supporting capacity and soft exchange point device function and performance etc., therefore optical fiber A kind of final form that will also develop to family as Optical Access Network.In fiber-to-the-home construction arrangement, products scheme it is left The speed of right the quality of network, the cost built and propulsion, it can be seen that the importance of ODN products schemes is self-evident.

Optical cable fiber-dividing box is common indoor and outdoor optical node product in FTTH-ODN networks, and optical cable fiber-dividing box is to be used for Optical distribution cable is realized by optical branching device and butterfly optical cable of registering one's residence after continuing and connected, and the molten of optical cable is completed in optical cable fiber-dividing box Connect, draw and connect and light splitting function.Since optical cable fiber-dividing box is different suitable for the light splitting of FTTH-ODN networks level-one or secondary light-splitting etc. Scene demand, and to meet the installation requirement of outdoor extension wall or pole, therefore optical cable fiber-dividing box is generally wall box in building.Because of light Cable fiber-dividing box is a kind of outdoor equipment, therefore it is required that weather and the severe working environment by drastic change can be supported, has anti-aqueous vapor The characteristics of condensation, waterproof and dustproof, insect-pest and the plague of rats, strong shock resistance damage capability.But traditional optical cable fiber-dividing box usually by Optical fiber cable termination case is made through simple repacking, and a closing type hole on the tank wall of babinet is used as into cable hole, and optical cable is drawn when connecing Need to be fixed in babinet again after stripping, but will be unable to realize in the spaces such as narrow and small corridor light current well, even if in sky Spacious field institute, since optical cable is needed through the string holes on babinet, not only increases difficulty of construction, and can not will draw and connect optical cable and draw In cartonning body and it is fixed.

In view of the above-mentioned problems, the disengaging cable machine of optical cable fiber-dividing box disclosed in the Chinese patent of Publication No. CN202041685U Structure, is characterized in that：Briquetting notch is provided with babinet tank wall, and briquetting notch bottom surface is provided with arc groove, only Need optical cable being positioned in lower arcuate slot and optical cable is fixed by briquetting, it is not necessary to optical cable is passed through into installation again Hole, so that more convenient operation, avoids wearing for optical cable and put.

The utility model provides a kind of new technical solution to solve the above problems at the same time.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of point for reducing optical fiber abrasion Fine case, has the advantages that the abrasion to optical fiber import and export can be reduced.

The above-mentioned technical purpose of the utility model technical scheme is that：One kind can reduce optical fiber mill The fiber-dividing box of damage, including babinet, the babinet side are offered into wire casing, and opposite side offers some branch holes, the inlet wire The first clamp assemblies being provided with for being clamped optical fiber and preventing optical fiber from wearing are slided in groove, slides and is provided with the branch hole For the second clamp assemblies for being clamped optical fiber and preventing optical fiber from wearing.

By using above-mentioned technical proposal, some optical fiber into wire casing at the same time by entering fiber-dividing box, into setting at wire casing The first clamp assemblies are equipped with, the first clamp assemblies can be gripped the optical fiber for entering fiber-dividing box, while the first clamping Component can be being slided into realizing in wire casing, so when optical fiber is subject to axial pulling force, can drive the first clamp assemblies into Realize and swing in wire casing, swung so as to fulfill optical fiber into the small range in wire casing, certain cushioning effect is played, so as to reduce Damage during optical fiber under tension；Optical fiber can be divided into some single optical fiber, each optical fiber list when going out fiber-dividing box Solely pass through outlet hole, slided in outlet hole and be provided with the second clamp assemblies, the second clamp assemblies can by fiber gripper, and When optic fibre force, optical fiber can drive the second clamp assemblies to be slid in outlet hole, so as to avoid optical fiber directly and outlet hole Side wall is there is a phenomenon where rubbing, so that frictional dissipation when reducing fiber-dividing box at optical fiber, and then extend to a certain extent The service life of optical fiber.

The utility model is further arranged to：First clamp assemblies include the card slot for being opened in inlet wire groove sidewall, institute State to slide in card slot and be provided with clamping piece, the clamping piece basal sliding is arranged in card slot, and the clamping piece upper end is used to block Connect optical fiber.

By using above-mentioned technical proposal, the upper end of clamping piece is used to clamp optical cable, and lower slide is connected in card slot simultaneously Slip can be realized, so when optical fiber is subject to external force, since clamping piece is by fiber gripper, so optical fiber can drive clamping piece to exist Realize and slide in card slot, so as to play the role of buffering to optical fiber.

The utility model is further arranged to：The card slot is opened up in cylinder, and offers use in inlet wire groove sidewall In the through hole of connection card slot, the diameter of the through hole is less than the diameter of card slot, and the clamping piece includes deck in disk form, institute Deck diameter is stated less than card slot diameter and is more than through-hole diameter, the deck is provided through the supporting rod of through hole setting, described Support shank diameter is less than through-hole diameter, and the post upper is connected to clip.

By using above-mentioned technical proposal, deck can move in card slot, and since the diameter of through hole is more than support The diameter of bar, so supporting rod can carry out 360 degree of movement in through hole, and due to post upper by clip by light Fibre blocks, thus can drive at the same time optical fiber realize it is small-scale rock, while play cushioning effect, avoid optical fiber from being subject to unexpected Damaged when pullling excessive.
