The present invention relates to an electrical connection configuration, and more particularly to an electrical connection configuration that is constructed to be re-flexible and waterproof.

A conventional heat generating device, such as a heat generating eye mask, is provided with a heat generating sheet inside the cloth sleeve. Since the heat generating sheet is provided with a plurality of electric heating wires, when the electric wires of the heat generating sheet are connected to the power source to heat the plurality of electric heating wires on the heat generating sheet, The heat energy emitted by the heat-generating sheet can be transmitted outside through the cloth cover, and is used as a warming or hot-applying eye to relieve sore eyes or promote blood circulation.

When the cloth cover of the above-mentioned conventional heat-generating device needs to be cleaned due to soiling, since the structure of the heat-generating sheet is not suitable for twisting, it is necessary to remove the cloth cover and clean it separately. If the heat-generating sheet is set to a water-washable structure, the electric heating wire and the electric wire are used. There are wires of different materials. Except that the joint is not easy to weld, the welded structure is easy to break and detach when repeatedly flexing. The position of welding is not waterproof when washing, making the heating wire and wire unsuitable with the whole heating piece. Washing together, there is a need to provide an electrical connection structure that is repeatedly deflected and does not easily break, detach, and waterproof the wire.

Since the existing electrical connection structure is easily broken and detached after repeated flexing, it is easily damaged when applied to a structure requiring water washing, such as a water-washable heat generating device. For this reason, the present invention utilizes the structure of the tight wire to match the flexible heating wire, and the electrical connection structure is waterproof and flexible, and is suitable for use in a water-washable heat-generating device.
