The connector comprises a connecting bracket with a groove-shaped cavity and a magnetic conductive elastomer filled in the groove-shaped cavity and strongly bonded with the connecting bracket. The upper surface of the magnetic conductive elastomer is flush with the upper surfaces of the main F rail and the auxiliary F rail. The connecting support is fixedly connected with the main F rail and the auxiliary F rail.
