Abstract: A carrier for the assembly, test and calibration of a mass air flow sensor on a production line. The support carrier consists of a structure having a well for receiving a first portion of the sensor head of the mass air flow sensor and a transverse air flow passage provided through the support structure aligned with the well and parallel to the top surface of the support structure. A clearance aperture connects the bottom of the well with an air flow passage and permits the sensor elements of the mass air flow sensor to be centrally disposed in the air flow passage. Sealing surfaces provided at the opposite ends of the air flow passage permit the carrier to be connected to a controlled source of air. Locating pins align the mass air flow sensor on the carrier with the sensor elements accurately positioned in the air flow passage.

Abstract: A sealed electrical connector includes one connector member having an oval-shaped cavity containing electrical contacts. A second connector member has a main body of a similar oval shape and having electrical contacts for mating with the contacts in the other connector member. A circular sealing boot is inserted into the cavity so as to deform to the oval shape, thereby providing lateral forces against the cavity wall which ensures that the sealing boot is retained in the cavity and promotes a tight seal when the main body of the second connector member is inserted into the cavity. The sealing boot is formed with elastomeric material into a circular cylindrical shape and is retained in the cavity even when the connector is disconnected.
