Abstract
The present invention provides a device and method for detecting a pin retention force of a locomotive connector. The device includes: a flexible detection film, a plurality of sensing units are distributed on the flexible detection film, and the flexible detection film passes through the flexible detection film. The sensing unit acquires the pressure signal corresponding to each pin on the connector to be tested; the lifting module is used to lift the flexible detection film, so that each pin on the connector to be tested is correspondingly contact a sensing unit on the flexible detection film; and an analysis processing module, the analysis processing module is electrically connected with the flexible detection film, and the analysis processing module is based on the pressure signal corresponding to each pin, Detecting the holding force of the pins; the present application improves the accuracy and versatility of detecting the holding force of the pins of the male connector for locomotives.
Description
technical field [0001] The invention relates to the technical field of locomotive production, and in particular, to a device and method for detecting a pin retention force of a locomotive connector. Background technique [0002] As the most widely used signal transmission device on locomotives, the reliability of the male connector will be affected by many factors such as the operation level of workers, multiple plugging and overhauling, and aging. Male connectors have problems with pin back or poor pin retention. This will cause some equipment to malfunction during the operation of the locomotive, and even cause the machine to break. Therefore, the problem of insufficient pin retention force of the connector, that is, the male connector, will seriously affect the normal operation of the locomotive. [0003] In the prior art, inspection methods for the pin retention force of the male connector mainly rely on visual inspection and hand touch. However, this inspection metho...
