Heatable radome structure and production method thereof

Abstract

The invention belongs to the automobile component technology field and provides a heatable radome structure and a production method thereof. The structure comprises a diaphragm, a heating wire and anouter plate. A coating is arranged on the heating wire, the heating wire with the coating is printed on the diaphragm according to a set layout to form an integral heating diaphragm piece. The radomestructure further comprises a conducting sheet and a connector. The heating diaphragm piece and plastic carry out insert molding so as to form an outer plate, a conductive connecting hole is arrangedbetween an end portion of the heating wire and the outer plate, the conductive connecting hole is filled with conductive metal slurry in a coating mode, the conducting sheet is electrically connectedwith the heating wire through the conductive metal slurry, and the connector is connected to the conducting sheet. The structure and the method have advantages that procedures of punching of the diaphragm, the heating wire and the conducting sheet, sealing of a welding hole and shielding of a chromium-plated part can be avoided; and a percent of pass is higher, the chromium-plated part used for shielding the sealing hole can be omitted. Compared with a scheme in the prior art, the scheme of the invention has advantages of a simple structure, simple procedure, a high binding force of a front cover plate and a rear cover plate and low cost.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a heatable radome structure and a production method thereof. Background technique [0002] The surface of the car radome is easy to freeze in cold weather. In order to ensure the effective penetration of radar waves, it is very necessary to take measures to remove the ice layer on the surface of the radome. The existing scheme for the heated car radome on the market is as follows: The wire is welded to the diaphragm according to the set layout, in which the end of the heating wire and the diaphragm and the plastic are insert-molded to form an outer plate. During the injection molding, the leakage on both sides of the heating wire in the opening area is guaranteed to connect the conductive sheet and the heating wire. Weld them together, use sealant to seal the diaphragm on the outer plate and bond the inner plate with the connector to the outer plate together. The c...

[0002] The surface of the car radome is easy to freeze in cold weather. In order to ensure the effective penetration of radar waves, it is very necessary to take measures to remove the ice layer on the surface of the radome. The existing scheme for the heated car radome on the market is as follows: The wire is welded to the diaphragm according to the set layout, in which the end of the heating wire and the diaphragm and the plastic are insert-molded to form an outer plate. During the injection molding, the leakage on both sides of the heating wire in the opening area is guaranteed to connect the conductive sheet and the heating wire. Weld them together, use sealant to seal the diaphragm on the outer plate and bond the inner plate with the connector to the outer plate together. The chrome-plated parts are clamped on the outermost side of the sign to cover the sealing hole. This structure can be seen The whole structure of the radome is complicated, the process is complicated, and the overall manufacturing cost is relatively high
