A glue-fillable drive housing structure

technical field

The invention relates to the technical field of lighting lamps, and in particular, to a structure of a drive housing that can be filled with glue.

Background technique

The traditional lamp drive power supply uses, for example, adhesive sealing to package the power drive board to achieve waterproof and dustproof purposes. Of course, the heat dissipation of the power drive board circuit can also be achieved by pouring silica gel into such a package structure. In some structures, such packaging structures are mostly assembled by a front cavity box and a rear cover plate. This packaging structure is relatively simple in appearance and structure, high in manufacturing cost, and inconvenient to assemble.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a drive housing structure that can be filled with glue in view of the above problems existing in the prior art.

The object of the present invention can be achieved by the following technical solutions: a drive housing structure that can be filled with glue, comprising two housings and a side cover, the two housings are spliced with each other to form a cavity for accommodating a power drive board, One side of the shell is provided with an encapsulation opening, and the encapsulation opening is provided with a glue-filling hole for pouring silica gel, the side cover is spliced at the encapsulation opening, and the two shells are connected by a buckle structure .

The working principle of the present invention is as follows: place the power drive board in the cavity, lock the two shells through the buckle structure, pour silica gel into the cavity through the glue filling hole, and then splicing the side cover at the packaging opening That's it.

In the present invention, by pouring silica gel into the cavity, the heat generated by the power drive board is transferred to the power supply shell through the silica gel; the setting of the glue filling hole facilitates the filling of the silica gel after fixing the power drive board, and at the same time prevents excessive glue filling Cause the silica gel to overflow the shell or the glue is too little, resulting in poor thermal conductivity; the installation of the buckle structure facilitates the assembly of the two shells; by setting the upper and lower shells as two identical shells, the production cost of the enterprise is reduced, In addition, when installing manually, two shells can be taken at random to assemble, so as to prevent the situation that the number of upper and lower shells does not correspond.

The buckle structure includes a male buckle arranged on one side of the shell and a female buckle arranged on the opposite side of the male buckle. When the two shells are spliced with each other, the male buckle is buckled with the spliced one. Inside the female snap of the housing.

The male buckle includes a plurality of convex parts arranged on one side of the casing and a buckle hole opened on the convex part, and the female buckle includes a plurality of convex parts arranged on the other side of the casing and matched with the buckle holes. When the two shells are spliced with each other, the buckles are buckled in the buckle holes of the shells spliced with them.

The two adjacent convex parts are connected by reinforcing ribs.

Both sides of the inner wall of the casing are provided with a plurality of step columns, and when the power drive plate is fixed in the cavity, the upper and lower end surfaces of the power drive plate are abutted against the step columns.

The shell is provided with a plurality of limit posts and a limit part on the limit post on the side close to the buckle. There is a limit slot for the reinforcement ribs to be embedded between the limit posts and the shell. When the block shells are spliced with each other, the reinforcing rib is embedded in the limiting groove of the spliced shell, and the limiting portion abuts against the side wall of the splicing rib.

The side cover plate is provided with a plurality of buckles, and the packaging opening is provided with a plurality of limit buckles that cooperate with the buckles. When the side cover plate and the shell are spliced to each other, the buckles are fastened to the casing. in the limit buckle of the shell that is spliced with it.

The shell is provided with a limit groove and a limit protrusion on the opposite side of the limit groove. When the two shells are spliced with each other, the limit protrusion is inserted into the spliced shell. in the limit groove.

A power cord is inserted on the power drive board, a power cord buckle slot for accommodating the power cord is arranged between the side cover and the packaging port, and a wire for the power cord to pass through is opened on the side cover hole.

The power drive board is plugged with a transmission line, and a half-line buckle slot for accommodating the transmission line is opened on the casing.

Compared with the prior art, the present invention has the advantages of facilitating the filling of the silica gel after fixing the power drive board through the arrangement of the glue-filling holes, and facilitating the assembly of the two shells through the arrangement of the buckle structure.
