After glue is poured into, the bonding to end cap and shell is realized, so as to fulfill the sealed connection to housing and end cap, but above-mentioned
One layer of sealing structure is only provided with structure, between end cap and shell, so that poor scarce with waterproof effect difference there are sealing effect
Point.
The content of the invention
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of the outer of Christmas lamp driving power
The assembling structure of shell and end cap, it has the advantages that sealing effect is good and good water-proof effect.
The shell of Christmas lamp driving power and the assembling structure of end cap of the utility model, including shell and be connected to outer
The end cap of shell afterbody, the side that end cap is located at shell are provided with the annular bound edge for being sleeved on housing exterior, the inner side of annular bound edge
Wall is close to the lateral wall of shell, and annular convex platform is provided with the interior bottom of end cap, is formed between annular convex platform and annular bound edge
The annular slot being inserted into for the end of shell, the end set of the shell on the inside of annular convex platform have annular nib, annular
The annular groove for annular convex platform insertion is formed between chimb and the madial wall of shell.
The shell of Christmas lamp driving power and the assembling structure of end cap of the utility model, wherein, shell is towards end cap
Annular convex rib is provided with the end face of side；By using this structure, after being poured into glue in annular slot, can increase
The contact area of glue and shell, so as to improve the adhesion strength of shell and end cap.
The shell of Christmas lamp driving power and the assembling structure of end cap of the utility model, wherein, annular convex platform direction
Ring-shaped depression is provided with the end face of shell one end；, can after being poured into glue in annular groove by using this structure
Increase the contact area of glue and annular convex platform, so as to improve the adhesion strength of shell and end cap.
The utility model passes through the setting of annular bound edge, annular convex platform, annular slot, annular nib and annular groove, end
The structure of labyrinth-like can be formed between lid and shell, so, after being poured into glue in annular slot and annular groove,
The sealing intensity between end cap and shell can be improved, so as to improve waterproof effect.
