Abstract

The invention discloses a measuring device and method for the intermatching gap of blind mating connectors, and relates to the field of measuring the intermatching gap between machine disks and backplane connectors, including: a calibration tool, which is provided with a groove, the depth of which is S is part of the pin length for docking the signal pin on the backplane connector with the chassis connector plus the thickness of the bottom of the backplane connector shell; and the analog chassis, which includes a chassis body; a plurality of chassis connectors, its Both are fixed on the disk body; at least one displacement sensor is fixed on the disk and is arranged adjacent to a disk connector, and the length of the part of the displacement sensor protruding from the disk beyond the disk connector is slightly greater than the depth S ; A displacement tester, which is connected with the displacement sensor and used to read the data of the displacement sensor. The invention can avoid the problem of poor consistency of measurement data caused by multiple measurements and calculations, and is not limited by test conditions. The whole test tooling is simple and easy to operate, with high test efficiency and high test accuracy.

Description

technical field [0001] The invention relates to the field of measuring the intermatching gap between a chassis and a backplane connector, in particular to a measuring device and method for a blind mating connector intermatching gap. Background technique [0002] The intermating clearance (Demated value) between the chassis connector and the subframe backplane connector directly affects the reliability of the product, and many signal failures are related to the excessively large value. Demated value specific reference figure 1 and figure 2 As shown, the factors that affect the Demated value include the processing and assembly errors of the machine disk, the processing and assembly errors of the sub-frame, and the deformation of the machine disk after being inserted and removed from the backplane. All influencing factors are in a normal distribution state, how to accurately and efficiently measure the Demated value has become an urgent problem to be solved in the design and...
