Abstract
The utility model relates to an anchor type grounding clamp, comprising an anchor type grounding assembly, wiring holes, copper riveting bolts, nuts, a cable and a heat-shrinkage sleeve. The wiring holes are respectively disposed on two ends of the cable and are provided with bolt connecting holes which are consistent with the bolt connecting holes in shape and position. Therefore, the anchor type grounding clamp has the advantages of convenient operation, good contact performance, low grounding resistance, large instantaneous impact current and the like.
Description
Technical field:
The utility model relates to the lightning protection hood type ground connection card of the outdoor radio frequency braid shielded of TD-SCDMA net feeder line.
Background technology:
In order to make mobile base station antenna-feedback system good earth, realize that the main feeder cable outer conductor links to each other with the earth, so in a single day the thunder and lightning electric shock takes place, can protect communication base station equipment and safe operation, reduce the noise that system produces because of electromagnetic interference simultaneously again.The mobile base station feeder line must adopt the ground connection card that cable is carried out ground protection before entering machine room.Mainly contain ring fastening type ground connection card, standard type ground connection card, matrix type ground connection card at present, they are mainly used in the ground connection of bellows coaxial-cable feeder these ground connection cards, and the TD-SCDMA mobile base station of 3G adopts braid shielded net cable to carry out the transmission of radiofrequency signal, designs this kind of utility model ground connection card for the requirement of satisfying braid shielded net cable grounding.
Summary of the invention:
In order to solve braid shielded net cable grounding, the utility model provides a kind of hood type ground connection card of new structure.The type ground connection card can satisfy easy to operate, and contact performance is good, and earth resistance is little, and the electric current of anti-the moment impact is big, and water resistance is good.All can satisfy 67 grades of classification of waterproof, electric wire and joint pulling-out force 〉=300N with actual using after tested, the moment impact electric current is greater than the specification requirement of 500A.
The technical scheme that the utility model solves is, hood type ground connection card, formed by anchor ear shape grounding assembly, wiring nose, copper riveted joint bolt, nut, cable, heat-shrinkable T bush, it is characterized in that: be respectively arranged with the wiring nose at the two ends of cable, described wiring nose is provided with bolt connecting hole, and bolt connecting hole pass and position set on bolt connecting hole and the anchor ear shape grounding assembly are consistent; Be provided with heat-shrinkable T bush at cable and wiring nose connection.The utility model structural design can guarantee excellent contact and less contact resistance, and the electric current of anti-the moment impact is big, can satisfy water resistance and requirement easy for installation again.The beneficial effects of the utility model are the demands that solved cable employing radio frequency braid shielded net cable lightning protection in the present 3G TD-SCDMA base station construction, use the requirement of full up foot " mobile communication base station lightning protection and ground connection design specification " after testing with actual field, and reduced cost.
