Adopt this kind of design, when getting electric plug 2 and bar base 1 contact and get the electricity, can form certain extrusion to sealing washer 231, because sealing washer 231 has elasticity, can make sealing washer 231 and conducting strip 11 closely laminate, make the outside moisture of conducting strip 11 can not get into from conductive terminal 22 position and get in electric plug 2, make and get electric plug 2 and have good waterproof nature, simultaneously, set up the terminal surface of sealing washer 231 free end into the plane, can make sealing washer 231 inseparabler with the laminating of conducting strip 11, waterproof nature is better.
