Technical Field

The present invention relates to a connector, and more particularly, to a connector adapted to electrically connect two cables.

background

On locomotives such as trains, it is often necessary to electrically connect two cables using connectors. Such connectors generally include a housing, an insulator received in the housing, and two flanges provided at both ends of the housing. The housing is typically secured to a stationary mounting base. An insulator is received in the housing, and two flanges are fixed to both ends of the insulator, respectively, but not to the housing. Thus, the insulator is movable relative to the housing. When the locomotive vibrates, the insulator can shift and impact the housing, which can lead to cracking of the insulator over time, which can lead to failure of the entire connector.
