Coordinate the guide surface being oriented to facilitate rubber plug to pass through through hole with through hole；By the setting of guide surface, through hole is passed through in rubber plug so that
During annular slot is clamped with through hole, it can be brought convenience to the process of rubber plug through through hole.
The driving power of the Christmas lamp of the utility model, wherein, guide surface is arcwall face；By the way that guide surface is arranged to
Arcwall face, it is possible to increase rubber plug coordinates the effect being oriented to through hole so that one end outside end cap of rubber plug can be more square
Just pass through through hole.
The driving power of the Christmas lamp of the utility model, wherein, the end set of the rubber plug on the inside of end cap has can
The slot by bar part insertion of button on power circuit board；By the setting of slot, button is inserted into slot by bar
In, during rubber plug promotes and presses bar, it can avoid the phenomenon of off normal occur by bar, so as to avoid departing from by bar
The phenomenon of rubber plug.
The utility model can coordinate the annular slot of clamping by being set on the lateral wall of rubber plug with the side wall of through hole；This
Sample one, enables to form disconnecting prevention structure between rubber plug and through hole, avoids rubber plug from occurring departing from end during being pressed
The phenomenon of lid, furthermore by setting the annular convex platform being coated on the lateral wall of rubber plug on the interior bottom of end cap, rubber plug is located at
The end set of end cap inner opposite end has ring-shaped step, and the height of ring-shaped step is higher than the height of annular convex platform, by using this
After kind structure, when pouring into glue on the interior bottom of end cap, and ensure that the height of glue is not higher than the height of ring-shaped step, so
One, ring-shaped step and annular convex platform can form stair-stepping structure, so as to increase connecing for glue and rubber plug and end cap
Contacting surface is accumulated, and then preferably can bond by rubber plug and end cap, further avoids rubber plug from occurring during being pressed
Depart from the phenomenon of end cap.
