Background technology
Ballast is the device commonly used on the illuminating lamp tube, existing ballast shell is divided into loam cake and base usually, finish the fixing of loam cake and base by screw, this design and fixed form mainly can cause following problem: (1) security performance is not enough, the used circuit board of ballast on the market generally is placed in the cavity of loam cake and base composition, binding post exposes, and this just makes that exposing terminal is vulnerable to the influence of external environment and can causes potential threat to user's safety; (2) fixed form falls behind, and traditional screw fixed form can be brought such as shortcomings such as disassembly and assembly trouble, cost are higher; In addition, existing ballast manufacturer considers for the cost aspect, often only designs two splicing ears, dispenses earth terminal, and this just makes that the security performance of ballast reduces greatly on the whole.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of electric ballast box that can address the aforementioned drawbacks.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of electric ballast box, comprise base and loam cake, base is provided with binding post, binding post exposes to the cavity body of base and loam cake composition, it is characterized in that: the pressing lid that covers binding post also is installed on the described base, and base or pressing cover the connection jaws that is provided with corresponding to binding post; The sidewall of described pressing lid and loam cake is equipped with buckle, and described base is provided with the draw-in groove that matches with buckle.
As the further improvement of such scheme, extend on the sidewall of described base to be provided with and clamp ear, described draw-in groove is located at and is clamped on the ear, is provided with the ccontaining hollow-out parts that clamps ear at pressing lid and loam cake sidewall corresponding to the position of draw-in groove, and described buckle is positioned at hollow-out parts.
Further, described base is provided with three binding posts, and base or pressing cover three connection jaws that are provided with corresponding to binding post.
Further, first connection jaws of being covered by pressing of described connection jaws and second connection jaws on the base cooperate and form.
Further, described base is provided with a crossbeam, on cover and be provided with the brace summer that combines with crossbeam.
In addition, be provided with simultaneously the reinforcement that is connected with base with crossbeam around the described crossbeam.
The beneficial effects of the utility model are: at first, the solid integrated design mode of the two-restriction that the utility model adopts buckle to cooperate and clamp ear to cooperate with hollow-out parts with draw-in groove, make and guaranteeing under the fastening prerequisite of loam cake and base the advantage that can also bring dismounting combined and instant, whole cost to descend; Secondly, the utility model has increased the terminal bonding lid, and entire circuit and binding post partly are placed in the cavity that base, loam cake and pressing lid formed, and has played safety and firm effect; In addition, the binding post of ballast is a trifocal, in the middle of earth terminal adding design, has further played and has guaranteed safe effect.
