Cable coupling component and method for jointing steel rail with cable using the cable coupling component

Abstract

The invention discloses a cable connecting component and a method of connecting cables with rails by using the same. The cable connecting component comprises a tapered bolt of which the head is connected with a track circuit cable and of which a shaft is provided with a cone part with a gradually reduced diameter from the head to the shaft; the cable connecting component also comprises a flexible sheath inserted on a rail web and a taper hole which can accommodate the cone part is arranged on the inner wall of the flexible sheath; one end t of the shaft of the tapered bolt far away from the head is through an inner hole of the flexible sheath, the outer wall of the cone part is held against the inner wall of the taper hole tightly, and the end of the shaft of the tapered bolt far away from the head is also locked with a nut. The cable connecting component and the method enable the tapered bolt, the flexible sheath and the end face of the rail web to stick tightly without gaps, which ensure that the cable connecting component can keep stable metallic performance and be not easy to rust during the long-term application.

Description

technical field [0001] The invention relates to a cable connection assembly, in particular to a cable connection assembly applicable to railway track circuit cables connected to railway rails, and a method for connecting cables and rails using the cable connection assembly. Background technique [0002] In the railway signal system, the train operation control information in the station control room is transmitted to the section line through the signal cable buried next to the railway track. A track circuit transfer box is installed at a certain distance on the section line. The signal cables are connected, the outlet end is connected with the track circuit cable laid on the ground, and the other end of the track circuit cable is connected with the rail, thus realizing the transmission of the train operation control information to the rails in each blocked section of the section line, see Figure 1 shown. [0003] The connection method between the existing track circuit cabl...

Problems solved by technology

Although this connection method has the characteristics of simple structure and wide source of components, there is inevitably a certain gap between the rail waist 7 and the bolt 3, the back-stop gasket 2, and the connector 4. After long-term use in the field, Rust on the contact surface between the rail waist 7 and the connector 4 will cause the contact resistance to increase and reduce the reliability of the track circuit

At the same time, because this connection method adopts a simple connection, large-scale mechanized equipment has been widely used for road maintenance on busy and heavy-duty trunk lines today. When the mechanical equipment cleans and vibrates the ballast at the bottom of the rail, it is easy to cause damage to the connecting piece 4, or even collide with it. Wound Track Circuit Cable 5
