Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see Figure 1-4 As shown, a new type of optical fiber distribution box includes a box body 1 and a box door 3 connected to the front side of the box body 1 through a hinge 2. The box door 3 can close the box body 1. The edge of the box door 3 A sealing strip 4 is glued and connected at the place, and the sealing strip 4 increases the airtightness of the box body 1. A connecting block 22 is welded on the back of the box body 1, and the connecting block 2...

The invention discloses a novel optical cable distribution box. The novel optical cable distribution box comprise a box body, hinges, a box door, sealing strips, a micro vacuum pump, an exhaust nozzle, a connecting pipe, a dust-collecting box, a dust-absorbing pipe, an installing plate, first bolts, a dustproof box, wire inlets, pressure plates, holding hoops, screws, through holes, traverse plates, second bolts, a fixing block, a filter element, a connecting block, an installing block, a fixing pin, a pin hole and an installing hole. According to the novel optical cable distribution box, thestructure is reasonable, the air in the dust-collecting box is pumped through the vacuum pump, the air pressure is reduced, the dust-collecting box sucks dust in the dustproof box through an air pressure difference, the dust entering a connection of a trunk optical cable interface and a distribution optical cable interface is reduced, and the influence on the communication transmission of opticalcables is avoided; the box body can be effectively fixed through the connecting block and the installing block, convenience is provided for installation and dismounting of the box body through the cooperation of the connecting block and the installing block, the box body can be prevented from falling from the installing block through the fixing pin and the pin hole, and the connection is stable and reliable.
Description
technical field [0001] The invention relates to an optical fiber distribution box, in particular to a novel optical fiber distribution box, which belongs to the technical field of communication device applications. Background technique [0002] With the full deployment of fiber-to-the-home access, the fiber optic cable distribution box, as an important wiring device used at the optical branch point, has been more and more used; the fiber optic cable distribution box is used outdoors, in corridors or The interface equipment for connecting the backbone optical cable and the distribution optical cable indoors; the general optical fiber distribution box is fixed on a vertical plane. [0003] When the optical fiber distribution box is installed in use, dust may enter the box, which may cause the interface between the main optical cable and the distribution optical cable to be contaminated with dust, and affect the transmission of communication between the main optical cable and t...
