The specific embodiment
Further illustrate the specific embodiment of the present utility model below in conjunction with accompanying drawing, hereinafter identical mark refers to identical element.
As Figure 1-3, the automobile safety system electronic control package comprises housing 1 and lid 2, the outer rim that lid 2 utilizes a plurality of screws 21 to pass lid 2 is connected with housing 1, circuit card 4 is installed in housing 1, Yaw rate sensor 3 is arranged on (referring to Fig. 3) on circuit card 4, the outer rim of lid 2 is extended location tongue piece 22 towards housing 1, is formed for accommodating the positioning groove 11 of location tongue piece 22 on housing 1.
Because the edge of lid 2 extends location tongue piece 22, location tongue piece 22 is inserted in positioning groove 11 on housing 1.In when vibration, 2 meetings of lid and housing 1 come in contact 11 li of positioning grooves, have reduced being arranged on the impact of the Yaw rate sensor in housing 1, thereby have improved sensor performance.
In the present embodiment, as shown in Figure 1, location tongue piece 22 and positioning groove 11 are rectangle.The location tongue piece 22 of rectangle can simultaneously play the effect of location, damping on X and Y-direction, and cost is easily processed, do not increased to the location tongue piece 22 of rectangle and positioning groove 11.In Fig. 1, directions X is horizontal direction in figure, and Y-direction is the vertical direction in figure.
