The invention discloses a seal cartridge and a brake pressure collecting device. The outer side cylindrical face of the seal cartridge is provided with an arc-shaped flange making contact with the inner wall of a through hole of a cavity of the brake pressure collecting device, water from air condensation can be prevented from entering a circuit board through a gap between the outer side of the seal cartridge and the inner wall of the through hole, and therefore the waterproof performance of the brake pressure collecting device is improved, and meanwhile the seal cartridge can be prevented from freely falling in the installing process. The inner side of the seal cartridge is provided with a step face making contact with the end face of a pressure sensor, water from air condensation can beprevented from entering the circuit board through the inner side of the seal cartridge, and therefore the waterproof performance of the brake pressure collecting device is further improved. The relative distance between a second step face on the inner side of the seal cartridge and the side face of the pressure sensor is larger than zero, and therefore the sufficient space can be reserved for installing the pressure sensor.
本发明公开了一种密封套及制动压力采集装置,密封套的外侧圆柱面上设置有与制动压力采集装置腔体的通孔内壁接触的圆弧状凸缘,可以避免空气凝结的水通过密封套外侧和通孔内壁之间的缝隙进入到电路板,从而提高了制动压力采集装置的防水性能,同时也可以防止密封套在安装过程中自由脱落。密封套内侧设置有与压力传感器端面接触的台阶面,可以避免空气凝结的水通过密封套内侧进入到电路板,从而进一步提高了制动压力采集装置的防水性能。密封套内侧设置的第二个台阶阶面与压力传感器侧面的相对距离大于零,从而可以为压力传感器的安装留有足够的空间。
