NOVELTY - The device has connecting elements (10,20) that are mechanically fixed through insertion of screw (14) into first conductive sleeve (12a) and second conductive sleeve (22a) of respective connecting element, so that current transmission path is formed. A second insulator (26) is formed by surrounding accidental contact of second connecting portion (22) and second conductive sleeve. The second conductive sleeve is provided by facing away from second connecting portion side, such that second conductive sleeve is provided in separated state against accidental contact.    USE - Electrical connection device used for connecting electrical high-voltage components such as synchronous or asynchronous machine, converter, transducer and battery used in vehicle such as electric, fuel cell or hybrid vehicle.    ADVANTAGE - Since the connecting elements are mechanically fixed through insertion of screw into sleeves of respective element, the contact resistance property and the shock protection property of electrical components against a human finger and objects are improved. The manufacturing cost of the electrical connection device is reduced. The structure of the electrical connection device is simplified.    DETAILED DESCRIPTION - The device has a first connecting element which is comprised with first connecting portion (12) having first opening formed transversely to direction of extension, and first conductive sleeve which is arranged coaxially with the first opening. A screw with screw head portion and bolt, is projected through the first opening and first conductive sleeve. The screw head portion is provided as opposite to the first conductive sleeve of the first connecting portion. A first insulator (16) is formed by surrounding accidental contact of the screw head portion and first connecting portion, and projected with respect to conductive sleeve, such that the conductive sleeve is provided in the separated state against accidental contact. The second connecting element is comprised with second connecting portion having second opening formed transversely to direction of extension, and second conductive sleeve which is arranged coaxially to the second opening of the second connecting portion.
