Abstract: An anti-loose data cable contains: an interface element, a first protective fixing layer, a second protective fixing layer, a third protective fixing layer, a positioning head, and a USB cable. The interface element is welded with the USB cable, on a connection area of the interface element and the USB cable is fixed the first protective fixing layer, and the interface element and the first protective fixing layer are accommodated in the second protective fixing layer, wherein a main part of the second protective fixing layer is accommodated in the third protective fixing layer, and the third protective fixing layer and the positioning head are integrally formed together.

Abstract: A type of tension detection-based headset with intelligent switching control is disclosed in the invention, which comprises a head wearing yoke and headphone speakers connected at the two ends of the head wearing yoke, inside the head wearing yoke a piece of elastic sheet steel is disposed further on which a force sensor is disposed. The said force sensor obtains a message in relation to the deformation of the elastic sheet steel by detecting any deformation of the said built-in elastic sheet steel and outputs a switch signal, after being processed by the measuring circuit, to the switch module which initiates automatic control according to the switch signal. The invention is for intelligent on-off control of the headphone which can be automatically turned on when worn on the head and automatically turned of when taken off, thereby elevating user convenience and reducing unnecessary power consumption.
