Abstract

A plug-in electronic energy-saving fluorescent lamp, which comprises a shell 6 of an ordinary lamp, a lampshade 5, a lamp holder and a lamp tube, a socket 9 with a groove is fixed inside the shell, and a plug 10 inserted into the socket groove is wrapped in a plastic shell. electronic ballasts. The ballast circuit is electrically connected to two groups of filaments and single-phase power supply incoming wires respectively through a connector composed of the metal plug piece on the plastic shell and the metal contact piece on the socket. Therefore, when the electronic ballast is damaged, it can be reused only after being pulled out and plugged into a new electronic ballast, so as to achieve the purpose of maintenance-free.

Description

Plug-in type electronic energy-saving fluorescent tool

The utility model relates to a kind of electronic energy-saving fluorescent tool, especially plug-in type electronic energy-saving fluorescent tool.

Known electronic fluorescent lamp, though given up the volume heaviness, the old-fashioned ballast that power consumption is big, and the employing electric ballast, but,, must ask special maintenance personal to change new ballast in case electric ballast damages because the lead-out wire of electric ballast all is fixed in respectively in separately the circuit one by one, general personnel are impotentia maintenances or change that the old friend claims that this light fixture is non-non-maintaining formula light fixture.

The purpose of this utility model provides a kind of electric ballast and changes non-maintaining easily formula electronic fluorescent lamp.

The purpose of this utility model is achieved in that it comprises the lampshade that is connected on the shell, fixing lamp holder below the lampshade, be inserted with fluorescent tube above the lamp holder, be rotated with socket with screw in the shell, socket is inconjunction with socket slot, stationary arrangement the metal contact pin of mutually insulated in the socket, the rear end of metal contact pin is electrically connected with two groups of filaments and single phase poaer supply inlet wire respectively, the front end of metal contact pin and pass the metallic plug sheet that the electric ballast that inserts socket slot behind the shell moulds on the shell and engage, the metallic plug sheet is communicated with the electronic ballast circuit of moulding in the shell.

Metallic plug sheet and socket have been formed demountable electrical connector like this.So whole ballast is easy to extract from socket or insert, in case the ballast in using damages, the ordinary people also can extract socket with the ballast that damages, and will continue to use behind the slotting people of good ballast, thereby reaches non-maintaining purpose.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structure principle chart of the present utility model.

Fig. 2 is the connector internal structural map.

Fig. 3 is the electric ballast external form figure with metallic plug sheet.

Fig. 4 is the situation that contact pin of rubber-like metal and the metallic plug sheet above the electric ballast join.

1 is fluorescent tube among Fig. 1, the 2nd, and lamp holder, the 3rd, the single phase poaer supply line, the 4th, attaching plug, the 5th, lampshade, the 6th, shell, the 7th, the socket line, the 8th, the socket fixed screw, the 9th, socket, the 10th, electric ballast, the 11st, be inserted in the filament pin in the lamp holder.Fluorescent tube 1 inserts in the lamp holder 2 by pin one 1, and the lampshade 5 that is being connected below the shell 6 is being fixed socket 9 with screw 8 in the shell, insert electric ballast 10 in the socket 9, socket 9 right sides are lines 7 of socket, and general line has the six roots of sensation, we see among the figure be outmost that.These lines are received respectively with on the 11 filament pins of representing and on the power line 3, and the 4th, the attaching plug on the power line.

Fig. 2 is that A among Fig. 1 is to view, its expression connector internal structure situation, 6 is bottoms of shell among the figure, the 8th, screw in the shell screw in order to fixed socket, the 9th, socket, the 7th, water the line of solid metal contact pin 13 in socket 9, the 14th, (in the middle of two guide edges is empty to the guide edge on the socket slot, is beneficial to the heat radiation of electric ballast.) the 10th, from the electric ballast that notch 15 inserts, a jiao of cutting ballast among the figure open, below we can see with the 13 metal contact pin of representing with 12 socket slots of representing, the 16th, draw the limit on the electric ballast.

Fig. 3 is the dorsal view of electric ballast, and the integral body of 10 expression electric ballasts among the figure has the ballasting circuit element in metallic plug sheet 17, the 19 expression ballast shells above the plastic housing 18 of ballast.

Fig. 4 is the contact pin of rubber-like metal and the metallic plug sheet above the electric ballast situation of joining on the socket.17 promptly is metallic plug sheet on the electric ballast among the figure, it is cast in the middle of the plastic housing 18 of ballast, the 13rd, the contact pin of rubber-like metal (do camber and reach the rubber-like purpose by metal contact pin here, but also can take the member that patches commonly used of other form, as when the plug on the electric ballast is the garden cylindricality, socket can be poroid.) the 14th, guide edge, the 9th, the socket section, the 12nd, socket slot, the 19th, be fixed on the circuit of electronic ballast element in the plastic housing 18, sort circuit designs according to the ordinary electronic ballast technology.
