Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 6, the utility model relates to an optical cable joint box of preferred embodiment, which comprises a housin, the casing includes casing 1, be located the lower casing 2 of casing below, it links firmly through the bolt with lower casing to go up the casing, it is equipped with transmission tank 3 to go up on the flange face of casing and casing down correspondingly, be provided with base 4 on the bottom surface of lower casing, the bottom of base sets firmly on lower casing, be equipped with two clamp splices 5 on the base correspondingly, the bottom and the base of clamp splice link firmly, be provided with erection column 6 between two clamp splices, be equipped with on the erection column and extend to the screw hole 7 of bottom surface from the erection column top surface, the screw hole inboard is provided with the internal thread, be provided with the perforation 8 with the screw hole intercommunication on the lateral wall of.

The utility model discloses an optical cable splice box is provided with two clamp splices on the base, has clearance 9 between two clamp splices, and like this, operating personnel need not the side head and can observe the position in clearance, and because the bottom of clamp splice sets firmly on the base, consequently it has certain elasticity, and operating personnel not only is convenient for insert the erection column between two clamp splices like this, and is convenient for fenestrate alignment to improve the efficiency of installation. During installation, an operator can align the through hole on the installation column with the gap. When the optical cable is connected, an operator penetrates the optical cable reinforcing core into the optical cable joint box from the transmission groove, then the optical cable reinforcing core passes through the gap and the through hole of the two clamping blocks from one side of the base and penetrates out from the other side, and the optical cable joint box is very convenient to use.

Preferably, the clamping blocks are arc-shaped clamping blocks.

Preferably, the mounting column is a hexagonal mounting column, and the inner side surface of the clamping block is matched with the mounting column.

The arrangement of the hexagonal mounting column facilitates the alignment between the mounting column and the clamping block, and meanwhile, the mounting column can be prevented from rotating.

Preferably, a fusion splice tray 10 is also provided within the housing.

Due to the arrangement of the fusion splice tray, the operation personnel can conveniently fuse the optical cables at the two ends.

Preferably, the shell is provided with a T-shaped wire pressing plate 11 which is fixedly connected with the shell.
