Description
Technical field
This utility model belongs to technical field of electronic devices, relates to a kind of fast-assembling ballast.
Background technology
Ballast is to play metering function on daylight lamp and produce the equipment of instantaneous pressure, it is to twine enamel-covered wire on the iron core that silicon steel makes to be made, the coil of such ribbon core, when moment, ON/OFF powered on, self-induction will produce high pressure, be added on the electrode (filament) at the two ends of fluorescent tube.This action hockets, and when starter (jump bubble) closes, the filament of fluorescent tube is by the conducting heating of ballast current limliting；When starter is opened a way, ballast self-induction will produce high pressure and be added on the two ends filament of fluorescent tube, and the phosphor powder that electron bombardment tube wall launched by filament is luminous, starter break-make several times repeatedly, will such action several times repeatedly, thus getting through fluorescent tube.When fluorescent tube normal luminous, internal resistance diminishes, and starter just remains open-circuit condition, and such electric current is worked by fluorescent tube, ballast with regard to stable, makes fluorescent tube normal luminous.Ballast divides electric ballast and Inductive ballast.
Existing ballast all needs perforate on housing to spread out of for cable, it is therefore desirable to carry out encapsulation process between cable and hole wall, brings bigger inconvenience therefore to the processing of ballast and dismounting, and sealing effectiveness is also poor.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of fast-assembling ballast, and technical problem to be solved in the utility model is: how ensureing excellent sealing effect while, increase the simplicity of dismounting.
The purpose of this utility model can be realized by following technical proposal: a kind of fast-assembling ballast, including housing, it is arranged on the ballast body in housing and binding post, it is characterized in that, described housing upper end open, described opening is provided with end cap, described end cap includes being in a cylindrical shape insertion section and plate-shaped cover plate, formation sealing that described insertion section is inserted in the opening of described housing and outer wall and opening inwall recline, described cover plate is resisted against the opening edge of housing along forming sealing, the sidewall of described housing and/or the cover plate of end cap are provided with joint, described joint one end is stretched into has socket one in housing, the other end stretches out housing and has socket two, described ballast body and/or binding post are connected to cable, described cable has plug, described plug can be plugged on socket one and form electrical connection.
This ballast is by designed joint on housing or on end cap, joint is provided with socket one and socket two, during installation, only need to ballast body and binding post be arranged in housing, then the plug on cable is inserted in the socket one of correspondence, then cover cover plate, in socket two, one cable of grafting can normally use again, easy for installation, originally it is at sealing state between joint and housing or cover plate, it is not necessary to carry out encapsulation process again.
In above-mentioned fast-assembling ballast, between described joint and the sidewall of housing and/or between joint and the cover plate of end cap, it is provided with Gask-O-Seal.By arranging Gask-O-Seal, it is possible to the gap between butt joint and end cap and joint and housing seals, further ensure good sealing property.
In above-mentioned fast-assembling ballast, the medial wall of described housing having inwardly projecting annular convex shoulder, described insertion section is inserted in housing and end is resisted against on annular convex shoulder.By the design of annular convex shoulder so that the sealing surface between end cap and housing is Z-shaped, extend the path of sealing, further ensure good sealing property.
In above-mentioned fast-assembling ballast, the inwall of described housing being additionally provided with annular seal groove, be provided with sealing ring in described annular seal groove, the inner ring of described sealing ring presses the outer surface being resisted against insertion section.The setting of sealing ring further ensures the sealing between end cap and inner walls, and sealing property is better.
In above-mentioned fast-assembling ballast, the opening edge of described housing also has the flange formed that stretches out, and described cover plate is resisted against on described flange, is connected by securing member between described housing and end cap.Flange can play position-limiting action, easy disassembly.
In above-mentioned fast-assembling ballast, between described cover plate and flange, it is additionally provided with O.The design of 0 type circle makes to define between end cap and housing dual-seal, and sealing property is more preferably.
Compared with prior art, this fast-assembling ballast has the advantage that 1, has socket one and socket two joint by design on housing or on end cap, during installation, only need to ballast body and binding post be arranged in housing, then the plug on cable is inserted in the socket one of correspondence, then cover cover plate, in socket two, one cable of grafting can normally use again, easy for installation, originally it is at sealing state between joint and housing or cover plate, it is not necessary to carry out encapsulation process again.2, the sealing road surface between end cap and housing is substantially in Z-shaped, and sealed pathway is long, and forms dual-seal, good seal performance by sealing ring and 0 type circle between end cap and housing.
