Description

Micro Cable Splice Box

technical field

The utility model relates to a micro-cable splicing box, which relates to an optical cable splicing box for various types of micro-optical cables (cluster type optical cables) and optical cable micro-sleeves.

Background technique

Underground pipelines in large and medium-sized cities are very crowded, and major telecom operators may lay optical cables in the same pipeline. Due to the relatively high density of micro-cables in the pipeline, there may be many splice boxes at some optical cable joints, plus The remaining cables left in the coil will make the whole manhole and handhole appear messy and crowded, which will also bring troubles to future maintenance work. In addition, the outer diameter of the micro-cable is small (between 3.9 and 5.6 mm), and there is no reinforcing core. Since the outer dimension of the ordinary optical cable joint box is relatively large, the fixing fixture of the optical cable is not suitable for fixing the micro-cable, so the ordinary optical cable joint box is used. Connecting the micro-cable cannot solve the problem of fixing and sealing the micro-cable. In view of the above problems, a new type of joint box for micro cables is needed to meet the needs of installation and construction.

Contents of the invention

The purpose of this utility model is to provide a kind of micro-cable splicing box for above-mentioned inadequacy, adopt rubber sealing plug, rubber sealing cone, fastening nut to seal and fix micropipe, micro-cable, and the housing of splicing box is provided with storage fiber tray, Compared with ordinary joint boxes, it is small in size and light in weight, and its internal structure is more suitable for the connection and installation of micro cables.

The microcable joint box is realized by adopting the following scheme: the structure of the microcable joint box has a shell, the shell adopts an open structure, the upper part of the shell is equipped with a shell cover, the four sides of the shell are provided with sealing grooves, and the shell is provided with There are several cable inlet holes, the cable inlet holes are equipped with seals or sealing plugs, the seals are provided with sealing seats, rubber sealing cones, and fastening nuts, the housing is provided with a fiber storage tray, and the fiber storage tray is provided with optical fiber connectors The protection slot is equipped with a fiber storage tray protection cover on the fiber storage tray.

When the micro-cable joint box is used, the micro-pipe with the micro-optical cable is fitted with a seal, and the sealing seat is squeezed on the front end of the micro-pipe. There is a rubber sealing cone at the outlet end of the micro-optical cable, and the rubber sealing cone is tightened by tightening the nut. Press it tightly in the gap between the sealed microcable and the microtube and make it bear part of the microcable tension, put the microcable on the optical fiber protection sleeve and introduce it into the fiber storage tray or use the fiber bundle splitter to introduce the corresponding storage fiber respectively Disc, weld the optical fiber and put the connector into the fiber connector protection slot, leave the remaining fiber disc around the fiber storage disc, cover the protective cover of the fiber storage disc, insert sealing strips around the housing, and cover the housing cover.

The micro-cable joint box has reasonable design, simple structure, small size and light weight, and its internal structure is more suitable for the connection and installation of micro-cables. The four sides of the micro-cable joint box are sealed with self-adhesive sealing strips, the cable inlet of the micro-cable joint box is sealed with double layers, the micro-pipe is sealed with rubber seals, and the micro-cable is sealed with rubber sealing cones. The tube was accidentally broken in the pipeline, causing water to enter the micro tube, which was also kept out of the splice box. Due to the small size of the joint box of the utility model, the installation in manholes and hand holes takes up little space, which brings convenience to operation and maintenance.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Figure 1 is a schematic diagram of a microcable splice box.

Fig. 2 is a schematic diagram of the opening and use state of the microcable splice box.

Fig. 3 is a schematic diagram of the micropipe and microcable sealing structure of the microcable joint box.

Detailed ways

Referring to accompanying drawings 1, 2 and 3, the structure of the microcable splice box has a housing 1, the housing 1 adopts an open structure, the upper part of the housing 1 is equipped with a housing upper cover 2, and the four sides of the housing 1 are provided with sealing grooves 6 for sealing A self-adhesive sealing strip is installed in the groove 6. The housing 1 is provided with fixing holes 3 . The housing 1 is provided with four cable inlet holes 12, and the cable inlet hole 12 is equipped with a seal 9 or a sealing plug. The seal 9 is provided with a seal seat 8, a rubber sealing cone 10, a fastening nut 11, and the housing 1 A fiber storage tray 4 is arranged inside, and an optical fiber connector protection groove 5 is arranged inside the fiber storage tray 4 , and a fiber storage tray protective cover is installed on the fiber storage tray 4 . The fiber storage tray 4 is fixed in the housing 1 by screws 7 . Seal 9 can adopt rubber seal. When the micro-cable joint box is in use, the micro-pipe 13 equipped with the micro-optic cable is put on the sealing member 9, and the sealing seat 8 is squeezed on the front end of the micro-pipe 13. There is a rubber sealing cone 10 at the exit end of the micro-optic cable 14, which is passed through the tight The fixing nut 11 presses the rubber sealing cone 10 into the gap between the sealing microcable 14 and the microtube 13 and makes it bear part of the microcable tension, and puts the microcable on the optical fiber protective sleeve 15 and introduces it into the fiber storage tray or adopts an optical fiber The bundle fiber splitter introduces the corresponding fiber storage tray 4 respectively, the optical fiber 16 is welded and the joint is put into the optical fiber joint protection groove 5, and the remaining fiber tray stays around the fiber storage tray 4.
