Electronic module wedge-shaped packaging slot locking force measuring system

Abstract

The invention discloses an electronic module wedge-shaped packaging slot locking force measuring system, and aims to provide a measuring system capable of measuring the locking force of a two-degree-of-freedom wedge-shaped locking strip. The method is realized through the following technical scheme: a rectangular short base and a rectangular long base which are in vertical lap joint with each other are adopted in the test module; the end face of the formed L-shaped vertical body is provided with positioning bolts which are arranged in a linear array and linear array grooves which are perpendicular to each other and are provided with pressure sensors on the inner sides; each pressure sensor is connected with a data acquisition instrument through a wire hole in the back end of the linear array groove, and the positioning bolts are combined with the pressure sensors and inserted into check blocks below the low-heat-conduction locking strips and the high-heat-conduction locking strips to adjust the test distance; the test module uploads a measurement result to the upper computer in real time through the pressure sensor, carries out dynamic test on the locking force of the wedge-shapedlocking strip, and transmits and displays the measurement result in real time.

Description

technical field [0001] The invention relates to a locking force measurement system of a wedge-shaped locking bar fixing device for an electronic module chassis slot. In particular, it is a system for measuring the locking force of the locking strips in the form of wedge packaging of aviation high-density electronic modules. Background technique [0002] With the rapid development of computer technology, the design of various hardware of the computer itself is becoming more and more sophisticated. Among them, the development of integrated circuits has made the analog circuits and discrete components with single functions and large volumes in the past replaced by highly integrated, small and bulky components. Many functions are replaced by the modular structure of resource sharing, which popularizes the concept of computer replaceable modules. With the development of electronic technology, electronic equipment has developed from discrete to integrated, and independent electro...

Problems solved by technology

Traditional locking force measurement systems can only test single-degree-of-freedom locking devices, especially for Figure 5 In the high thermal conductivity locking strip 4, the stroke on the two degrees of freedom is related to the locking force. If a single degree of freedom locking force test system is used, it cannot be measured accurately, which leads to the high thermal conductivity locking strip 4 There are no accurate parameters in the application process, the screw rotation torque cannot be provided during the design process, and the pressure between the locking bar and the module cannot be estimated at the same time

[0004] The published "A Measuring Device for Clamping Force of Clamping in Stamping Dies of Large and Small Sizes" in the prior art can only measure the locking force of a single degree of freedom; the measuring distance of the locking force cannot be flexibly adjusted; most of the locking force measurements are The description of the measuring device does not form a real-time locking force measurement system, and it is impossible to realize the real-time change measurement of the locking force under vibration and overload conditions, the change of the locking force loading process, etc.
