A flat wire motor winding structure with a copper wire inner cooling structure comprises an iron core, a plurality of armature grooves are formed in the iron core at intervals in the circumferential direction, insulation paper is arranged on the inner wall of any armature groove, and a plurality of copper wire combination structures arranged in the radial direction are arranged in any armature groove in a penetrating mode. Each copper wire combination structure comprises two copper wires which are arranged in parallel and fixedly connected, at least one groove is formed in the opposite side faces of the two copper wires in the extending direction of the copper wires, the grooves penetrate from the end faces of one ends of the copper wires to the end faces of the other ends of the copper wires, and the two grooves form a cooling channel. After the copper wire combination structure is subjected to wire insertion, connection and other processes, main heating parts in each layer of winding copper wires are provided with cooling channels, cooling liquid directly cools the copper wires through the cooling channels in the copper wires and makes full contact with the interior of the armature, direct contact cooling of the cooling liquid with main heating points of the armature and the copper wires is achieved, and the better cooling effect is achieved.

The present invention provides a conductive rail connector and a conductive rail assembly, which belong to the field of rail transportation. The conductive rail telescopic connector is composed of a conductive copper strip, a sliding core plate and a core plate cover plate as the core part, and a rail body transition plate nested in the sliding core plate and fixed in the center position and a socket rail body nested in both ends of the sliding core plate and telescopically slid to form a complete expansion and telescopic head. The conductive copper strip has a middle rigid section and an S-shaped flexible section that is telescopic at both ends. The rigid section is superimposed with the sliding core plate and the core plate cover plate as a whole. The rail body transition plate is nested in the sliding core plate, and the socket rail body is nested in both ends of the sliding core plate; the end of the flexible section of the conductive copper strip is connected to the socket rail body. The above-mentioned conductive rail telescopic connector can flexibly telescope and slide while maintaining good conductivity between adjacent conductive rails, and can reduce the installation space and meet the insulation spacing requirements in a highly integrated environment.

This invention relates to a heat transfer protective film for metal corrosion protection, comprising a heat-resistant layer coated on one side of a base film, and an adsorption layer, a strong anode layer, and a weak anode layer sequentially coated on the other side of the base film. Sacrificial anode cathodic protection is an effective method for metal corrosion protection, while heat transfer technology transfers graphic coded information onto a substrate using a heat transfer printer or similar method. Because the coating can be prepared in advance, it can form heat transfer protective films with multiple functions. By preparing an anode coating containing an active metal, coating it as a heat transfer protective film, and then transferring it onto a metal substrate, the sacrificial anode material protects the cathode metal while imparting graphic coded information to the metal substrate. This represents a new metal corrosion protection mode that adapts to the development of the information age.
