Waterproof joint of I-beam type vehicle dynamic load cell

Abstract

The invention relates to the field of sensors, and provides a waterproof connector of an I-shaped beam type vehicle dynamic weighing sensor. The waterproof connector comprises an I-shaped beam type elastomer, end covers at the two ends, a cable and an air pipe; the I-shaped beam type elastomer is fixedly connected with the end covers through screws; the end cover at one end of the sensor serves as a line-outgoing end cover of the sensor, and the end cover at the other end of the sensor serves as a non-line-outgoing end cover of the sensor; a communicated cavity is formed in the I-shaped beam type elastomer, the two ends of the interior of the cavity are provided with lead cushion blocks matched with the cavity, and the cable penetrates through the air pipe to be connected with a sensor measuring unit through the lead cushion blocks, stretches out from the line-outgoing end cover of the sensor and then is fixed through line-outgoing sealing. According to the waterproof connector of the I-shaped beam type vehicle dynamic weighing sensor, by adopting end cover sealing and line-outgoing sealing, the sealing effect of the sensor can be effectively guaranteed, insulating media in the internal environment of the sensor are kept stable, and therefore the problems that signals are abnormal and the performance is unstable due to the fact that the sensor is sealed improperly are solved.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a waterproof joint of an I-beam type vehicle dynamic weighing sensor. Background technique [0002] Usually the performance of the sensor will be affected by the insulation resistance, especially the sensitivity and zero drift of the piezoelectric sensor will change with the change of the insulation value of the sensor. The insulation value of the sensor is determined by the insulation medium of the sensor itself and the insulation medium of the internal environment of the sensor. When the insulation medium of the sensor itself meets the insulation conditions, but the internal environment insulation medium does not meet the insulation requirements, the performance of the sensor will still change. The internal environmental insulation medium of the sensor is directly related to the sensor seal. If the sensor is not well sealed, the environmental insulation medium changes, which affects the...
