The present invention relates to a waterproof battery case, consists of a case member, an electrode plate set and a sealing connector. Connection surfaces of a base and a top cover of the case member are oppositely installed with a flange and a concave slot, and a resilient sealing unit is embedded in the concave slot; the interior of the base is installed formed with two opposite inner walls for the installation of battery; the electrode plate set is fastened on the inner ends of the two opposite inner walls according to the circuit layout, and wires connected to positive and negative joints extend to a wall hole pre-formed on the base; the sealing connector has a tubular main body allowing the wires to penetrate, a second connection part of the main body is sleeved with a resilient sealing pad then inserted in the wall hole, and further fastened with a fastening unit, the exterior of a first connection part of the main body is formed with at least two arc-shaped clipping sheets arranged in an annular state, a resilient binding ring is sleeved in the arc-shaped clipping sheets, and a tightening unit is fastened with the first connection part, such that the radial inner wall of the tightening unit presses the arc-shaped clipping sheets so as to bind the wires through the binding ring. The present invention provides an effect of multiple sealing, such that liquid, moisture or dust are effectively prevented from entering the case member. |
