Abstract
The utility model discloses a grounding structure for a lightning protection direct current feeder cable of a distributed base station, and the grounding structure comprises the direct current cable and a junction box; the junction box comprises a box body which is provided with an incoming hole and an outgoing hole, and an insulated patch panel which is arranged in the box body; an incoming wiring terminal of the insulated patch panel is electrically connected with a non-shielded direct current cable; an outgoing wiring terminal of the insulated patch panel is electrically connected with a core wire of a shielded direct current cable; a metal shielded layer of the shielded direct current cable is connected with the insulated patch panel through a metal fixing piece; and the incoming wiring terminal is electrically connected with the corresponding outgoing wiring terminal through a lead. The utility model aims to solve the problem that because the direct current feeder cable is led into a machine room, the shielded layer may lead in lightning current, the metal shielded layer of the direct current feeder cable is disconnected through a grounding box at the direct current feeder cable inlet of the machine room, so that the lightning current is directly grounded through a metal snap ring before entering the machine room along the metal shielded layer when lightning occurs, and the core wire enters the machine room through the grounding box.
Description
Technical field
The utility model relates to the mobile communication distributed base station, especially relates to the ground structure of the anti-thunder and lightning direct-current tie cable that is used for distributed base station.
Background technology
For avoiding the influence of thunder and lightning, the DC feedback cable generally adopts shielded type cable, metal screen layer two-terminal-grounding when wiring.At present; The earthing method that gets into the DC feedback cable of distributed base station is: with the metal screen layer of metal clasp chucking DC feedback cable; After making it closely to contact and doing preservative treatment with metal screen layer, through ground wire with metal clasp with arrange reliable the connection outdoorly.But; When thunder and lightning takes place; Thunder and lightning can be incorporated in the machine room along metal screen layer; If at this moment indoor metal screen layer ground connection is improper, will cause producing arcing or electric discharge phenomena between heart yearn earth terminal and the metal screen layer of DC feedback cable, directly influenced the equipment operation safety of base station.
Summary of the invention
The utility model purpose is to provide a kind of ground structure of the safe and reliable anti-thunder and lightning direct-current tie cable that is used for distributed base station.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The said ground structure that is used for the anti-thunder and lightning direct-current tie cable of distributed base station of the utility model comprises direct current cables and interconnecting device; Said interconnecting device is made up of with the insulation joint plate that sets within it the box body that offers into and out of the line hole; The inlet wire binding post of said insulation joint plate is electrically connected with non-shielding direct current cables; The outlet binding post of insulation joint plate is electrically connected with the heart yearn of shielding direct current cables, and the metal screen layer of said shielding direct current cables is connected with the insulation joint plate through metal fixing; Said inlet wire binding post is electrically connected through lead with corresponding outlet binding post.
Said metal fixing is a metal clasp, and said metal clasp is connected with the earth connection of drawing outside the box body.
The utility model just is to solve because the DC feedback cable is introduced machine room; Screen maybe be with the problem of lightning current introducing; Break off through the metal screen layer of said ground connection box with the DC feedback cable in machine room DC feedback cable porch, metal screen layer directly is connected with outdoor ground connection row through metal clasp, like this; Lightning current directly passed through metal clasp ground connection along metal screen layer when thunder and lightning took place before getting into machine room, and heart yearn gets into machine room through the ground connection box.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the said ground structure that is used for the anti-thunder and lightning direct-current tie cable of distributed base station of the utility model comprises direct current cables and interconnecting device; Said interconnecting device is made up of with the insulation joint plate 2 that sets within it the box body 1 that offers into and out of the line hole; The inlet wire binding post 3 of said insulation joint plate 2 is electrically connected with non-shielding direct current cables 4; The outlet binding post 5 of insulation joint plate 2 is electrically connected with the heart yearn of shielding direct current cables 6, and the metal screen layer of said shielding direct current cables 6 is connected with insulation joint plate 2 through metal clasp 8; Said inlet wire binding post 3 is electrically connected through lead 7 with corresponding outlet binding post 5, and said metal clasp 8 is outwards drawn earth connection 9.
