PROBLEM TO BE SOLVED: To provide a device for allowing a current collecting trolley to come in and out, satisfying the demand on the safety contact protection, having a short structural length, and providing a current creeping distance with a minimum length agreed with the safety standard. SOLUTION: In this device for allowing a current collecting trolley to come in and out from a long plastic profile of a contact wire having conductive rails, a rear end of a funnel body 4 fitted to an inner outline of a long plastic profile 2 is insertable into the long plastic profile 2 in an engaged and connected state, and a sleeve 5 connecting the long plastic profile 2 and the funnel body 4, surrounds the long plastic profile 2 in an engaged and connected state to easily manufacture and assemble the funnel body with a short structure while ensuring the desired contact protection. |
