Abstract: The present invention provides a fixing device for installing a pressure-type airbag sensor. The fixing device for installing a pressure-type airbag sensor includes a holder having a disk shape, a cover coupled to the holder and having a sensor unit disposed at an upper end thereof, and a connector housing disposed at a lower end of the cover. The cover may include a cover body having a disc shape. Reverse rotation prevention protrusions protruding outward may be formed at intervals at a plurality of positions on an outer circumference of the cover body. Rotation guide protrusions may protrude from the plurality of positions of the cover body, and corners thereof may be formed in a predetermined curvature. The rotation guide protrusions may be formed to correspond to the number of rotation locking parts formed on an outer wall of the holder.

Abstract: The present invention provides a fixing device for installing a pressure-type air bag sensor, the fixing device comprising: a disc-shaped holder; a cover coupled to the holder and having a sensor part disposed on the top thereof; and a connector housing disposed on the bottom of the cover, wherein the holder has a holder body formed in a disc shape, an outer wall having a predetermined height is formed along the outer circumference of the holder body, a ring-shaped seal is formed through insert-injection molding to have a predetermined radius inside the holder body, and protrusion parts having a predetermined curvature are formed at the upper surface part and the lower surface part of the holder body.

Abstract: An electronic relay includes: a housing having an interior space therein and a lateral side and a lower side of which are opened, a board installation part being formed along a periphery of the opened side of the housing; a printed circuit board a periphery of which is inserted into and installed in the board installation part of the housing, for shielding the opened side of the housing and performing a switching function; a lower cover for shielding a lower side of the housing, one side edge of the printed circuit board being fixed to the lower cover; and terminals ends of which are electrically connected to the printed circuit board and opposite ends of which pass through the lower cover to protrude to the outside.
