Abstract

A breathable component for automotive electric and electronic devices and a manufacturing method for the breathable component. The breathable component comprises: a rubber element (3), a coating film patch, and a protective cover (4). The coating film patch comprises an expanded polytetrafluoroethylene microporous membrane (1) and coated onto the surface thereof a hydrophilic group-containing coating (2), where the rubber element (3) and the coating film patch are hot-press welded into a weldment, and the protective cover (4) is arranged outside the weldment. The manufacturing for the breathable component comprises the following steps: manufacturing of an expanded polytetrafluoroethylene microporous membrane; preparation of a coating agent; manufacturing of a coating film; manufacturing of a coating film patch; and manufacturing of a breathable component: preparation of a rubber element, of a coating film patch, and of a protective cover, hot-press welding of the rubber element and the coating film patch into a weldment, inspection of welding surfaces, mounting of the protective cover onto the weldment, inspection, and packaging. The breathable component ensures that a phenomenon of fogging-condensation and dust accumulation does not occur in a housing for automotive electric and electronic devices, serves as an alternative for conventional headlight breathable cap or plug, requires no change to an original housing structure, and is capable of implementing highly efficiency press-fit assembly.

Description

technical field [0001] The invention relates to the field of moisture-permeable components, in particular to a moisture-permeable component for automotive electrical and electronic equipment and a manufacturing method thereof. Background technique [0002] The theory of defogging and decondensing the air hole of the curved tube of the European car lamp, there is a sponge inside to prevent dust, and the air in the lamp can be moved out and in with the change of the temperature inside the lamp, so as to quickly realize the defogging and decondensing in the lamp Exposure, bent tube ventilated car lights soon after the use of dust and electrical components rust inside the shell. [0003] The dew condensation theory of Gore Company in the United States: the lamp is through the air convection inside the lamp and the outside of the lamp to establish a kind of air pressure balance. The water vapor in the lamp will be discharged outside the lamp as the temperature inside the lamp ris...
