Abstract
The utility model discloses a mixed type grounding device for interrupting introducing of lightening in a cable of a distributed base station. The mixed type grounding device comprises a metal box body, a plurality of cable inlet holes, a plurality of cabinet outlet holes, an optical cable grounding device, a direct-current feed cable grounding device, a GPS (Global Positioning System) coaxial cable grounding device and a control cable grounding device; a plurality of cable inlet holes and a plurality of cable outlet holes are formed on the wall of the box body; and the optical cable grounding device, the direct-current feed cable grounding device, the GPS coaxial cable grounding device and the control cable grounding device are arranged in the box body. The mixed type grounding device disclosed by the utility model has the advantage of being capable of solving the problem owning to lightning protection on cables, direct-current feed cables, GPS coaxial cables and control cables of the distributed base station; the cables are respectively connected with corresponding cable ports on a housing, and the corresponding cables are led out of the cable outlets and connected to corresponding equipment, so that various cables are grounded outdoor, and the purpose of interrupting the lightning current introducing into a machine room by virtue of shielding layers of the cables and metal components can be achieved at last.
Description
Technical field
The utility model relates to the distributed communication base station lightning protection system, especially relates to distributed base station and interrupts the hybrid earthing device that thunder and lightning is introduced from cable.
Background technology
Distributed base station generally is provided with optical cable, DC feedback cable, GPS coaxial cable and control line.For avoiding the impact of thunder and lightning, the present mode of taking is: ground connection on Shelf is adopted optical cable metal outer jacket and optical cable strengthening core in the lightning protection of optical cable; The lightning protection of DC feedback cable is adopted ground connection in the DC distribution case in the DC feedback cable introducing machine room; The lightning protection of GPS coaxial cable is adopted the GPS coaxial cable is incorporated in the equipment again ground connection; The lightning protection of control line is adopted control line ground connection in calculator room equipment.Although aforesaid way also can be protected calculator room equipment, play the effect of shielding lightning current, can not avoid lightning current to introduce the problem of machine room by above-mentioned cable, and earth connection is too many, wiring is mixed and disorderly, brings many convenience to constructing operation.
Summary of the invention
The utility model purpose is to provide a kind of distributed base station to interrupt the hybrid earthing device that thunder and lightning is introduced from cable, both safe and reliable, save cable, again constructability operation.
For achieving the above object, the utility model/utility model can be taked following technical proposals:
Distributed base station described in the utility model interrupts the hybrid earthing device that thunder and lightning is introduced from cable, comprise metal case, be opened in a plurality of cables on the described box wall into and out of the hole, and be arranged on optical cable ground device, DC feedback cable earthing device, GPS coaxial cable earthing device, control cable earthing device in the box body; Be fixed with metal ground plate in box body, the earth connection of described metal ground plate extends outside the box body; Described optical cable ground device comprises and is arranged on the metal ground plate the first metal fixing that is used for clamping optical cable metal sheath, and is used for the second metal fixing of clamping optical cable metal strengthening core; Described DC feedback cable earthing device comprises for the metal fastener that connects the direct current cables metal screen layer, with into and out of binding post, the metal fastener is electrically connected with metal ground plate, describedly is electrically connected by wire into and out of binding post, and turnover binding post and wire all insulate with metal case; Described GPS coaxial cable earthing device is made of the coaxial cable protector, and described coaxial cable protector earth terminal is electrically connected with metal ground plate; Described control cable earthing device is made of the control line protector, and described control line protector earth terminal is electrically connected with metal ground plate.
