| 20110287673 | HIGH CONDUCTIVITY ENERGY-SAVING CLAMPING DEVICE - The high conductivity energy-saving clamping device comprises a clamp and a cable fixed upon the clamp. Inside the cable, the conductive material protrudes and is set on the juncture of the clamp and the external conductor. When the clamp is connected to the external conductor, the conductive material and the external conductor contact and meet. This invention possesses the following advantages: it simplifies the production technology, lessens raw materials needed for production and hence saves resources and cost by the direct contact of the conductive material and the external conductor; moreover, due to the increase of conductive contact area, it enhances the electrical conductivity by 10% to 15% compared to those common clamps which use tooth-like conductive parts to connect the external conductor. Meanwhile, the invention greatly decreases environmental pollution by omitting the plating process of tooth-like conductive parts. | 11-24-2011 |
