Abstract
The utility model relates to a connecting piece, particularly a special connecting piece for a grounded downlead of a concrete rod and particularly a novel and special connecting screw bolt for a grounded downlead of a concrete rod. The utility model comprises nuts, a screw rod and a shim, wherein the screw rod is connected with the nuts and the shim is arranged on the screw rod. The nuts form screw connection with the screw rod, and the shim is fixedly arranged on the screw rod. The utility model has the advantages of simple structure, artful design, convenient operation and simple disassembly, enhances the connection tightness, reduces the contact resistance of connection points, can discharge easily, can prevent effectively the counterattack phenomenon from happening and enhances the lightning withstand level of lines.
Description
Technical field
The utility model relates to a kind of connector, refers in particular to the connector of gear with concrete rod grounded downlead special use, is specially the special-purpose connecting bolt of novel gear with concrete rod grounded downlead.
Background technology
At present, the structure that connects the connecting bolt of ground lead in gear with concrete rod grounded downlead and the bar comprises nut, the screw rod that is connected with nut, and be located at pad on the screw rod.Nut is fixedlyed connected with screw rod, and pad is actively socketed on the screw rod.Yet, when using the connecting bolt of this structure that gear with concrete rod grounded downlead is connected with ground lead in the bar, because it is not high to connect tightness, thus the contact resistance height of tie point, thus earial drainage influence, cause and strike back phenomenon.
Summary of the invention
The utility model provides a kind of novel gear with concrete rod grounded downlead special-purpose connecting bolt for the problems referred to above that the connecting bolt that solves ground lead in existing connection gear with concrete rod grounded downlead and the bar exists.
The technical solution of the utility model realizes by following structure: the special-purpose connecting bolt of a kind of novel gear with concrete rod grounded downlead, comprise nut, and the screw rod that is connected with nut, and be located at pad on the screw rod; Nut is connected with screw flight, on spacers setting and the screw rod.During use, screw rod is stretched in the concrete bar, be connected with the nut on the ground lead in the bar, pad is attached to concrete bar outer wall, and the ground connection band iron is placed between pad and the nut, and nut is fastening, thereby make pad more be close to the outer wall of concrete bar, the interior ground lead of gear with concrete rod grounded downlead and bar is linked together.
In order to make connection more fastening, a nut shim can be fixedlyed connected with nut, like this, when clamp nut, nut shim just is crowded together with ground connection band iron and pad, has increased contact area, thereby makes connection more fastening.
The utility model is simple in structure, design ingeniously, easy to use, dismantle easy, can increase work efficiency greatly, compare with prior art, connect tightness and improve greatly, the contact resistance of tie point reduces greatly, earial drainage smoothly, can prevent to strike back the generation of phenomenon effectively, improve the lightning withstand level of circuit, have very high popularization and practical value.
