Abstract

The utility model discloses a finger nail type switch for a fluorescent lamp with the function of a glow starter. The utility model is provided with a couple of contacts for replacing the glow starter on the basis of an existing finger nail type power switch, the contacts are switched on by consecutively pressing a nail press button, small bulges on the press button are passed by a crown bar, and the work of the utility model is realized by pushing an elastic contact piece to be deformed. After a lamp filament is preheated, a user looses hands to make a ballast of a lamp tube conducted under an induction high pressure. The utility model is a power switch which is suitable for the lighting power utilization of the fluorescent lamp.

Description

Nail type switch for fluorescent lamp

The utility model relates to electric switch peace switching plate accessory, the switch that specifically a kind of fluorescent lamp that replaces starter is used.

As everyone knows, people are usually adopting the method for decontroling behind the direct overlap joint of its lead-in wire emergent under the situation that starter lost efficacy.The abundant preheating of filament therebetween, ballast coil induction high pressure causes gas ionization in the fluorescent tube and conducting during disconnection.Utilize the Chinese patent 86204747 of present principles to disclose switch with mechanical take-off device, because the organization plan of this device is limit, mechanism is big, does not adapt to the knockdown dull and stereotyped switch of present use, the installation requirement on the socket.

The purpose of this utility model is that a kind of above-mentioned same principle of utilizing will be provided, and pedals in existing nail type on the basis of board-like unit switch plate to have made improved nail type switch for fluorescent lamp.

Its technical scheme increases by one group of contact and realizes on existing switch base shell.

Nail type switch for fluorescent lamp of the present utility model, comprise nail button, seesaw, fulcrum, plectrum, two tagblocks and a seat shell, it is characterized in that: the last angle of nail button is provided with a projection, the ladder hole of a correspondence is set, mounting spring and push rod in the through hole on the seat shell of boss, one end of push rod is corresponding with raised position, the other end is over against a metallic elastic contact, and this contact connects a wiring pile crown, and another wiring pile crown is then corresponding with contact to separate setting.Constitute 3 pair of contact with it by the metallic elastic contact, and be connected with tube filament respectively, promptly two statures with the starter lead-in wire are connected.

The advantage of the technical program is the structure compact, does not increase the overall dimensions of whole switch module, is suitable for independent assortment installation on flat switch, socket, and measured result shows that it can reach the electrical equipment standard-required of regulation.

Fig. 1 is the structural representation of embodiment switch.

Fig. 2 is an electric hookup.

Below further make description of drawings:

Referring to Fig. 1, two projectioies are arranged on the angle of nail button 1, this example uses one individual, plays the usefulness of promotion push rod 12, loads onto stage clip 2 in the button 1, plectrum 3.Seesaw 4 is stirred by plectrum 3, and the tagblock 7 of its fulcrum and power supply links together.Seesaw stir Shi Yiduan and power supply tagblock 6 with contact contact power supply inserted.The 5th, a shell also is provided with two outer dress foramen alares except that receiving to load onto to state on the seat shell, as installing and fixing with the switch plate body other part.Seat shell left-front corner place offers the ladder hole of mounting spring 11 and push rod 12 usefulness, and on the default position of pile crown 8 above metallic elastic contact 9 is installed present shell, pile crown 10 and pile crown be 8 vertical, corresponding, separate, and forms a contact gap.

Entity schematic diagram after the switch assembling shown in Figure 2.The wiring of its two tagblocks and pair of contact lead-in wire pile crown is such: two tagblocks 6,7 are plugged among the live wire, ballast Z connects with live wire, be access to the filament foot of fluorescent tube L again, the filament one pin earth connection of the fluorescent tube other end, two pin of the filament that is left are access to the both sides, contact, (being two pin that connect starter originally) pile crown 8 meets A, and pile crown 10 meets B.

During work, push to nail button 1, power supply is received the two ends of fluorescent tube, continue pushing button 1, its projection bar 12 that bears down on one makes metallic elastic contact 9 and pile crown 10 1 end in contact, A, B be short circuit for it, power connection, and filament begins rapidly pre-warming, loose one's grip then, keep power position, contact flicks, and produces at ballast under the effect of high pressure, make gas ionization in the fluorescent tube and keep the power circuit conducting, fluorescent lamp is lighted.

Claims (1)

1, a kind of nail type switch for fluorescent lamp, comprise nail button (1), seesaw (4), fulcrum, plectrum (3), two tagblocks (6,7) and the seat shell (5), the last angle that it is characterized in that nail button (1) is provided with a projection, on the seat shell of boss, a corresponding ladder hole is set, spring (11) and push rod (12) are installed in the through hole, one end of push rod is corresponding with the position of projection, the other end is over against a metallic elastic contact (9), contact (9) is connected with power supply wiring pile crown (8), another wiring pile crown (10) is corresponding with contact, separate to be provided with, between formed pair of contact lead-in wire be connected with tube filament respectively.
