Novel cable assembly transient fault detection device and method

Abstract

The present invention provides a novel cable assembly transient fault detection device and method. The device comprises: a general base of a vibration device; a plurality of mounting brackets fixed on the general base of the vibration device; a plurality of signal transmission process cables; and The number of the signal transmission process cables is the same as the signal output process cables; the instantaneous on and off fault detection equipment is provided with a plurality of connectors. The invention is suitable for detecting whether the electrical connectors, components and other points connected to the cables in the random vibration stress screening of the cable components to be tested produce instantaneous disconnection faults of microsecond level or above, and can also be used for detecting electrical connectors, components, etc. Whether components and other points that are not connected to the shielding wire produce instantaneous connection faults above the microsecond level during the above dynamic process, it is convenient to timely eliminate the cable components under test with hidden faults and improve the cable fault screening ability.

Description

technical field [0001] The invention relates to a novel cable component transient fault detection device and method. Background technique [0002] In the product signal system, the cable assembly is a key component of system power supply and signal transmission, and its performance reliability is directly related to the performance and reliability of switchboard products. [0003] Due to the characteristics of the cable assembly manufacturing process itself and the complexity of the production process control, in order to ensure the quality of the cable, it is very necessary to perform process screening on the solder joints and crimping points of the cable plug (seat) after the completion of the production. Remove the cable network with quality defects in time. The original cable assembly fault detection method is to fix the cable net on the vibration tooling, and rely on the vibration control device to apply a corresponding level of stress to the cable. After the vibrati...

Problems solved by technology

[0006] (2) The vibration device used for laying cable assemblies in the original fault detection method can no longer meet the design and manufacturing trends of three-dimensional and flat cables, and the device and signal transmission mode need to be optimized.

The original device has a simple structure and a single function. It bends and coils the cable net, binds the outside with a nylon wire sleeve, and then fixes it on the vibrating table to receive excitation.

Due to the three-dimensional and flat design and production of the cable net, the cable net presents a three-dimensional or flat structure. The original tooling is only for the installation of flat cables, and cannot realize the fixing of three-dimensional and flat cables.
