Heating wire connecting structure, window cover and manufacturing method

Abstract

The invention belongs to the technical field of automobile heating radars, and provides a heating wire connecting structure, a window cover and a manufacturing method.The heating wire connecting structure comprises a diaphragm, a conduction sheet part and a circuit connecting piece, a heating wire is arranged on the diaphragm, the conduction sheet part is installed on the diaphragm, and the conduction sheet part comprises a main body part and clamping jaw parts located at the two ends of the main body part; the heating wire is electrically connected with the inner side face of the main body part, a clamping jaw hole matched with the clamping jaw part is formed in the membrane, the clamping jaw part penetrates through the clamping jaw hole and is clamped on the membrane after being bent, and the circuit connecting piece is electrically connected to the outer side face of the main body part. The method has the advantages that the metal sheet and the heating wire are arranged on different sides of the membrane, the heating wire is not affected by shearing of the edge of the metal sheet all the time in injection molding and subsequent procedures, the heating wire is protected, the relative position of the metal sheet and the heating wire is fixed, the conductivity and welding connection reliability of the heating wire are improved, and the service life of the heating wire is prolonged. The connection reliability is high.

Description

technical field [0001] The invention belongs to the technical field of heating radar, and relates to a heating wire connection structure, a window cover and a manufacturing method. Background technique [0002] Lidar benefits from the development of autonomous driving, and the application of lidar is becoming more and more extensive. It is estimated that by 2026, the domestic market demand for lidar is expected to reach 10 billion yuan, and the window cover is an indispensable and important part of lidar. Its The function is to protect the laser radar from being affected by the environment. When the existing heatable window cover is connected with the heating of the diaphragm, the shrapnel sheet directly presses the heating wire. In this way, the shrapnel sheet has the ability to disengage the heating wire. risk, and because the shrapnel sheet and the heating wire are located on the same side, that is, connected to the heating wire from the front, affected by the shearing of...
