USB connecting line joint

Abstract

The invention discloses a USB connecting line joint. The USB connecting line joint, which comprises a fixing assembly and a USB male head assembly used for being connected with a USB female head; thefixing assembly is provided with a male head groove used for containing the USB male head assembly, the rear end of the groove body is provided with a wire hole for a USB wire to penetrate through, part of the USB male head assembly is exposed out of the male head groove, the USB male head assembly and the fixing assembly are fixedly connected in the mode that resin is injected into the male headgroove, and when the USB male head assembly is inserted into the USB female head, the fixing assembly is clamped and fixed in a sunken square groove in the JRU case and plays a role in fixing. The USBconnecting line joint is inserted into the USB female head on the JRU case, and a screw is screwed into and penetrates out of a threaded through hole in a position fixing column, so that the screw abuts against the upper wall and the lower wall of the sunken square groove respectively, and effective connection and position fixing of the USB connecting line joint and the USB female head on the JRUcase can be achieved.

Description

technical field [0001] The invention relates to the technical field of USB connection wires, in particular to a USB connection wire joint. Background technique [0002] The external physical interface for obtaining data from the Judicial Recording Unit (JRU) of the existing EMU train control vehicle equipment is a USB female head. During the daily operation and maintenance of the train, the data acquisition method of the JRU chassis is to insert a USB cable with a USB male head to connect to the U disk, but this method is only applicable to manual data acquisition when the train is stopped. In order to realize the automatic real-time acquisition of JRU data, it is necessary to connect the JRU data automatic acquisition equipment through a connecting line with a USB male head when the train is running or in a static state. [0003] In the prior art, the USB female connector on the JRU chassis is located in the concave square groove of the chassis panel, and the traditional U...

AI Technical Summary

Problems solved by technology

[0005] Insert the traditional USB cable with USB male head to connect to the USB female head on the JRU chassis, lack of position fixing function, the male head of the USB cable is easy to loose from the USB female head on the JRU chassis during the long-term running of the train

In addition, the long-term relative mechanical vibration of the USB male head and the USB female head will also cause poor contact of the connector and unstable signal transmission

[0006] Aiming at the problems in the prior art that the male head of the USB cable is easily loosened from the USB female head on the JRU chassis, and the long-term relative mechanical vibration of the USB male and USB female heads leads to poor contact of the connector, no effective solution has been proposed yet.
