[0013] (1) In the present invention, the wire is first passed through the sealing gasket, the wire is electrically connected to the lead terminal, and the support is threadedly fixed in the cavity so that the O-ring is pressed tightly against the end face of the cavity. This is the first waterproof sealing measure; the nut joint is rotated to apply downward pressure to the sealing gasket, and the sealing gasket is guided by the reduced diameter portion so that the sealing gasket shrinks and deforms toward the center, thereby making the wire in close contact with the sealing gasket. This is the second waterproof sealing measure. Through the double waterproof sealing measures, the product has the advantage of good waterproofness.

[0014] (2) The utility model exposes the cavity to the field of vision of personnel by quickly disassembling the support member, which facilitates the quick electrical connection or disassembly of the wires and the lead terminals, making the product easy to disassemble.
