Description

TECHNICAL FIELD

[0001] The utility model belongs to ballast technical field, especially electronic ballast. BACKGROUND

[0002] Electronic ballast is the device that plays the role of current limiting and produces instantaneous high voltage on the fluorescent lamp, which is made of enameled wire wound on the iron core made of silicon steel. When the coil with the iron core is turned on and off, high voltage is generated by self-induction, which is applied to the electrodes at both ends of the fluorescent lamp. This action is alternating, and when the starter is closed, the filament of the lamp is heated by the current limiting conduction of the electronic ballast.

[0003] The existing electronic ballast is mostly fixed on the lamp holder of the fluorescent lamp by screws. When a fault occurs, tools are needed to remove the electronic ballast, which is complicated to disassemble and assemble, inconvenient to operate, and low in efficiency.

[0004] The existing patent document (publication number: CN219592659U) discloses an electronic ballast, which has screw grooves at both ends of the electronic ballast body for inserting screws, a slide seat is connected to the bottom of the slide seat, screw holes are formed in the upper part of the slide seat for fixing the electronic ballast body by screws, and the electronic ballast is fixed by screws. The same technical problems exist. SUMMARY

[0005] The utility model aims at solving the above technical problems in the prior art, and provides an electronic ballast, which has a novel structure, is simple to disassemble and assemble, replaces the fixing mode of bolt connection, and is labor-saving and convenient.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0007] An electronic ballast comprises a base and a ballast body, characterized in that: the base is symmetrically provided with side plates, the side plates are provided with clamping spring plates, and the two oppositely arranged clamping spring plates clamp the ballast body on the base. The electronic ballast has a novel structure, is simple to disassemble and assemble, replaces the fixing mode of bolt connection, and is labor-saving and convenient.

[0008] Further, the base is provided with a limiting pin, the ballast body is provided with an ear plate, and the ear plate is provided with a limiting hole corresponding to the limiting pin. The ear plate cannot be freely separated from the limiting pin, so that the ballast body is limited on the base, and the installation is stable and reliable.

[0009] Furthermore, the limiting pin includes a fixed post and a limiting end. The limiting end is located on the fixed post, and the limiting hole includes a first hole and a second hole. The first hole and the second hole are connected, and the cross-sectional diameter of the first hole is larger than that of the second hole. The first hole corresponds to the limiting end, and the second hole corresponds to the fixed post. During installation, the limiting end is first passed through the first hole, and then the ear plate is moved laterally so that the fixed post enters the second hole. At this time, the limiting end is misaligned with the first hole, and the limiting end prevents the ear plate from freely detaching from the limiting pin. Combined with the clamping action of the retaining springs on both sides on the ballast body, the free sliding of the ballast body can be restricted, so that the ballast body is limited on the base, resulting in high installation stability.

[0010] Furthermore, the bottom of the limiting pin is provided with a threaded end, and the base is provided with a threaded hole corresponding to the threaded end. The limiting pin is detachable, ready to be installed and used immediately, flexible and convenient. Rotating the limiting pin up and down can change the distance between the limiting end and the base, thus adapting to ear plates of different thicknesses, making it highly adaptable.

[0011] Furthermore, the base is provided with mounting through holes. Screws are inserted through the mounting through holes to fix the base to the lamp holder of the fluorescent lamp, making installation convenient.

[0012] Furthermore, both ends of the retaining spring are equipped with mounting parts, which are fixedly connected to the side plate by screws. This ensures reliable fixation, easy assembly and disassembly of the retaining spring, and convenient replacement if damaged.

[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0014] During installation, first squeeze the retaining springs to increase the clamping space between the two relatively distributed retaining springs. Place the ballast body into this clamping space, then pass the limiting end through the first hole. Next, move the ear plate laterally so that the fixing post enters the second hole. At this time, the limiting end is offset from the first hole, and the limiting end prevents the ear plate from freely detaching from the limiting pin. Combined with the clamping action of the retaining springs on both sides, the free sliding of the ballast body can be restricted, so that the ballast body is limited on the base, resulting in high installation stability. This method of fixing instead of bolt connection is simple to disassemble and assemble, saving effort and convenience. Attached Figure Description
