Abstract: An underframe end structure without a bolster beam for a rail vehicle, including an underframe end beam, an underframe edge beam, a coupler mounting base, coupler support beams, and oblique support beams, where the front of the coupler mounting base is connected to the underframe end beam through the oblique support beams, two sides of the coupler mounting base are connected to the underframe edge beam through the coupler support beams, so that quadrilateral frame structures are respectively formed on the two sides of the coupler mounting base, the oblique support beams form an included angle of 55° to 80° with a forward opening, and the coupler support beams form an included angle of 120° to 140° with a backward opening.

Abstract: A device for electrically grounding bundled cables includes a first half component having an outer surface portion and an abutting surface portion, and a second half component having an outer surface portion and an abutting surface portion. The outer surface portion of the first half component and the outer surface portion of the second half component each define at least one groove longitudinally extending therealong for accommodating one of a plurality of cables held closely together in a bundled configuration. The abutting surface portion of the first half component and the abutting surface portion of the second half component are configured for engaging and cooperating with one another to form a grounding structure.
