Disclosed is a vertical type connecting terminal for a storage battery, the vertical type connecting terminal including: a body unitwhich includes an insertion portionwhich is formed in a cylindrical shape having a cut-out at one side, an electric power outletwhich is formed opposite to the cut-out of the insertion portion, and a pair of elastic pieceswhich extends in a radial direction from both ends of the cut-out of the insertion portionand has therein arc-shaped portions', respectively; a fastening memberwhich includes a washer memberwhich has inside thereof arc-shaped grooves&#x2032; into which the arc-shaped portions&#x2032; of the elastic pieceare inserted such that the washer memberis coupled to an upper portion of the elastic pieceand adjusts an interval between the elastic pieceswhile moving vertically, a T-shaped tightening boltwhich is positioned below the elastic pieceand has a bodyto be inserted into a through holeformed in the washer member, and an elongated head, and a tightening nutwhich is fastened to the tightening boltfrom an upper side of the washer memberand allows the washer memberto move vertically, in which the tightening bolthas protruding portionswhich are formed at both ends of the headand each have an inner inclined surface&#x2032; so that a thickness of the protruding portiondecreases upward, the protruding portionsare disposed to transverse the elastic piecesin a width direction of the elastic pieces, and outer inclined surfaces, which correspond to the inner inclined surfaces&#x2032; of the protruding portions, are formed at both sides in a width direction of the washer member

Vertical type connecting terminal for storage battery

A winder for an electrode assembly of a rechargeable battery for improving space usage is disclosed. The winder includes a plurality of spools supplying a negative electrode member, a positive electrode member, a first separator member, and a second separator member, a mandrel stacking and spirally winding the first separator member, the negative electrode member, the second separator member, and the positive electrode member supplied by the spool, a first frame accommodating a predetermined number of spools from among the plurality of spools and the mandrel, a second frame connected to the first frame and accommodating other spools from among the plurality of spools, a reorienter installed between the first frame and the second frame and reorienting a progressing direction of one of the members, and a position controller controlling a position of the member that passes through the reorienter and progresses towards the mandrel.

Winder for electrode assembly of rechargeable battery

The storage battery connection terminal comprising: an insertion unit formed in a shape of a curved; a clamping unit formed by extending end portions of the insertion; and a power withdrawal unit formed to be extended from the other end portion of the insertion unit, in which the insertion unit, the clamping unit and the power withdrawal unit are manufactured by molding a single panel. The clamping unit includes a lower plate formed to be inclined by extending one end portion of the insertion unit so as to support the clamping bolt, and an upper plate formed to be inclined by extending the other end portion of the insertion unit so as to be disposed in parallel to the lower plate, on which the clamping nut is rested.

Connecting terminal for storage battery

A power supply apparatus for an electric bicycle is disclosed. The apparatus may include i) a battery pack and ii) a keybox connected to the battery pack and controlling on/off operations of the power supply apparatus. The keybox may further include i) a key set configured to receive a key cylinder that is moveable according to the rotation of a key inserted into the key box, ii) a contact terminal that includes a first plurality of sub-terminals, iii) a terminal base including at least one second sub-terminal connectable to and detachable from at least one of the first sub-terminals and iv) a keybox case configured to receive the key set, the contact terminal, and the terminal base. The terminal base may have a plate shape with a polygonal periphery surface at least part of which contacts an inner portion of the keybox case.

Power supply apparatus for electric bicycle

In a storage battery connection terminal comprising: an insertion unit of a cylindrical shape with an open end; a clamping unit for adjusting a diameter of the insertion unit by adjusting a gap between a pair of elastic plates; and a power withdrawal connecting a connection terminal, wherein the insertion unit, the elastic pieces of the clamping unit and the power withdrawal unit are formed in one piece through a forging process, the power withdrawal unit is connected at a position spaced apart from a lower portion of the insertion unit by a predetermined distance, in which a hole for inserting the connection bolt having a head of a rectangular panel shape is formed, and a resting groove with an open side is formed on a bottom surface so that a portion of the head of the connection bolt can be rest.
