MAP SENSOR FOR MOTOR VEHICLE

摘要

The present invention relates to a map sensor for a vehicle, which can improve the reliability of a product by preventing the penetration of foreign materials into a pressure sensor. The map sensor comprises a housing composed of a body which has a fixed internal space and has a through-hole for communicating with the outside, and where an accommodating groove on the edge of the through-hole is formed, and a connector which is included at one side of the body; a pressure sensor which is included at one side of the internal space communicated with the through-hole in order to recognize the pressure of air flowing into the inside; a printed circuit board which is electrically connected with the pressure sensor in order to measure the recognized pressure by the pressure sensor; and a foreign material inflow preventing unit which is included in the accommodating groove of the body in order to prevent the inflow of foreign materials contained in the entering air through the through-hole into the pressure sensor. Through the present invention, the attachment of foreign materials on the surface of a map sensor can be controlled by preventing the penetration of foreign materials into the inside of the map sensor for a vehicle in order to preventing defects in the map sensor and extend the life of the map sensor, thereby improving the reliability of the product.
