Abstract: A new booster cable for motor vehicle includes a first cable body. The first cable body includes a first insulation and a first conductor located inside the first insulation. A first temperature warning color strip is embedded on the first insulation. The first temperature warning color strip contacts with the first conductor. The booster cable further includes a second cable body. The second cable body includes a second insulation and a second conductor located inside the second insulation. The first cable body and the second cable body are connected in parallel. By adopting the temperature warning color strip, the booster cable of the present invention solves the problem of faster aging of booster cable for motor vehicle due to temperature rise during use and at the same times, it warns the user to keep naked hands away from electric wires before it returns to the normal temperature completely.

Abstract: 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.

Abstract: A clamp with lamp, particularly useful for attaching to an automobile battery, or similar rechargeable battery, when charging or otherwise working with the battery, is disclosed. The clamp with lamp is configured to provide a convenient source of light during nighttime or other low-light conditions and to provide an automated means for turning the light on and off during use. The clamp with lamp includes an LED lamp disposed on the upper jaw of the clamp, a battery disposed in a battery case inside the handle and a switching mechanism. A switching mechanism is actuated when the jaws of the clamp open, thereby providing power to the LED lamp. When the clamp is engaged with the automobile battery, and when the jaws are closed, the switching mechanism turns off the LED lamp to save electricity. The clamp is small, handy, elegant, and durable.
