Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
A fireproof grounding fixture for optical cables comprises a grounding component 200 and a fixing component 100, wherein the grounding component 200 comprises two sealing cover plates 210 used in cooperation, a sealing gasket 230, a fixing bolt used for connecting the two sealing cover plates 210, and a metal foil, the sealing gasket 230 is arranged between the two sealing cover plates 210, one end of the metal foil is connected with an optical cable armor, and the other end of the metal foil is in contact with the outer wall of the sealing cover plate 210, the fixing component 100 comprises a fixing plate 120 and a movable plate 110, clamping grooves 112 matched with the outer wall of the sealing cover plate 210 are respectively arranged on the fixing plate 120 and the movable plate 110, one end of the fixing plate 120 is bent downwards to form a fixing part 121, one end of the movable plate 110 is hinged to the fixing plate 120, and the other end of the movable plate 110 is detachably connected to the fixing plate 120, in the embodiment, can adopt if the buckle, connected mode such as bolt, concrete connected mode does, and fixed plate 120 can dismantle with fly leaf 110 and be connected one end and all be provided with the bolt hole, is provided with fixing bolt (not shown) in the bolt hole, and for the ease of installation, this embodiment sets the bolt hole on the fly leaf 110 to waist type hole 113 very much, and the bolt of being convenient for inserts in the bolt hole, and metal foil material matter is the copper preferably, and electric conductive property is better, be provided with stationary blade 111 that is used for connecting the ground connection cable on the fly leaf 110, the convenience is used for fixed ground connection cable when improving ground connection stability under special operating mode.
