Connector for storage battery

The utility model relates to a storage battery connector device, the storage battery connector is formed by an annular clamping portion and a wiring portion through a one-body formation method. The annular clamp portion is formed with a left and a right clamp arms which are symmetrical, the end portions of the two clamp arms are respectively extended with a set of extendible arms which are in parallel, perforations and screw holes are respectively arranged on the two sets of the extendible arms, thereby lock screws can penetrate and locking. One end side of the annular clamping portion is provided with the wiring portion, the center of the wiring portion is provided with one or more than one notches of proper depth, thereby the wiring portion is divided into two or more than two small wiring portions. Because of the design of the notches, the clamp arms of the annular clamp portion are extended to the whole annual portion, thereby the backward tension of the annular clamp portion is greatly reduced, a clamp hole is averagely condensed, and the inner face of the clamp hole can be completely and closely contacted with a power connector of the storage battery to increase the electrical conducting effects.
