A kind of LED fluorescent lamp lamp holder
Technical field
The present invention relates to a kind of LED fluorescent lamp, relate in particular to a kind of structure of LED fluorescent lamp lamp holder.
Background technology
Usually can run into such problem when fluorescent lamp is installed, after the end with lamp inserts lamp bracket, often use the conductive base pin that hand touches the lamp other end.There is not electrical structure in traditional fluorescent lamp because of fluorescent tube inside, the hazards of getting an electric shock when yet just not having fitting operation.Because LED has plurality of advantages such as low energy consumption, high light efficiency, long service life, therefore, the LED illuminating lamp tube replaces traditional fluorescent tube gradually, and begins to be widely used in room lighting.Yet two pins of general LED fluorescent lamp two ends lamp holder connect in inside, live wire of electrical network (L) and zero line (N) must be connected on the normal luminous lighting of two ends ability of LED fluorescent lamp respectively, yet go into live wire (L) in a termination of LED fluorescent lamp, touch the danger that the other end just has electric shock with hand.
Summary of the invention
Technical problem to be solved by this invention is: a kind of LED fluorescent lamp lamp holder of getting an electric shock of preventing is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of LED fluorescent lamp lamp holder, it comprises: king light head spare, be immobilizated in first printed circuit board (PCB) and spring mountings on the king light head spare, be sheathed on spring on the spring mountings, be contained in the king light head spare and can with respect to the rotary switch spare of king light head rotation, be snapped in front and back connector on the rotary switch spare, with front and back connector second printed circuit board (PCB), and the fluorescent tube connector of front and back connector phase fixing of fixing mutually; Described king light head spare is provided with two conductive poles, on described first printed circuit board (PCB) at least one lead is installed, described lead is connected with guide pillar by first printed circuit board (PCB), described spring mountings is provided with at least one sheet metal, described lead is connected with sheet metal, described front and back connector is equipped with at least one spring probe, described second printed circuit board (PCB) is connected with spring probe, be provided with spacing fixture block in the described king light head spare, described rotary switch spare is provided with triangular groove, is provided with the limited mouth that matches with spacing fixture block in the described triangular groove, clamping part and guide ramp.
The invention has the beneficial effects as follows: by being provided with spacing fixture block in the described king light head spare, described rotary switch spare is provided with the triangular groove of accommodating spacing fixture block, be provided with the limited mouth, clamping part and the guide ramp that match with spacing fixture block in the described triangular groove, can prevent to get an electric shock when installation personnel from installing fluorescent lamp.

The specific embodiment
See also Fig. 1 to Fig. 4, a kind of LED fluorescent lamp lamp holder 100, described LED fluorescent lamp lamp holder 100 comprise king light head spare 1, be immobilizated in first printed circuit board (PCB) 2 and spring mountings 3 on the king light head spare 1, be sheathed on spring 4 on the spring mountings 3, be contained in the king light head spare 1 and can with respect to the rotary switch spare 5 of king light head rotation, be snapped in front and back connector 6 on the rotary switch spare 5, with front and back connector 6 second printed circuit board (PCB) 7, and the fluorescent tube connector 8 of front and back connector 6 phase fixings of fixing mutually; Described king light head spare 1 is provided with two conductive poles 10, on described first printed circuit board (PCB) 2 at least one lead 20 is installed, in the present embodiment, on described first printed circuit board (PCB) 2 two leads 20 are installed, this lead 20 is connected with conductive pole 10 by first printed circuit board (PCB) 2, described spring mountings 3 is provided with several sheet metals 30, and in the present embodiment, described sheet metal 30 is a copper sheet.Described lead 20 is connected with sheet metal 30, at least one spring probe 60 is installed on the described front and back connector 6, in the present embodiment, two spring probes 60 are installed on the described front and back connector 6, described second printed circuit board (PCB) 7 is connected with spring probe 60, the pad of described second printed circuit board (PCB) 7 is welded with lead, communicates with the tube power line.Be provided with spacing fixture block 11 in the described king light head spare 1, described rotary switch spare 5 is provided with triangular groove 50, be provided with the limited mouth 500, clamping part 501 and the guide ramp 502 that match with spacing fixture block 11 in the described triangular groove 50, described king light head spare 1 is provided with receiving space 12, described spring mountings 3, spring 4 and rotary switch spare 5 all are contained in this receiving space 12, described king light head spare 1 is provided with the groove 13 that communicates with receiving space 12, and described rotary switch spare 5 is provided with the protuberance 51 that is snapped in this groove 13.This protuberance 51 can rotate in groove 13, described front and back connector 6 is provided with four barb portions 61, described rotary switch spare 5 is provided with the recess 52 that matches with barb portion 61, described barb portion 61 hooks on recess 52, thereby make rotary switch 5 and front and back connector 6 fixing mutually.
When fluorescent lamp is not installed on the lamp socket, the spacing fixture block 11 of described king light head spare 1 is positioned at limited mouth 500, at this moment, switch revolving part 5 can't rotate, in the present embodiment, the lamp holder of fluorescent-lamp tube one end adopts the lamp holder 100 of the band spring among the present invention, other end lamp holder adopts conventional not with the lamp holder of spring, when being installed on fluorescent lamp on the lamp socket, lamp holder 100 with the band spring among the present invention snaps in the lamp socket earlier, do not rotate no power after snapping in, can not cause other end lamp holder charged, thereby can prevent to get an electric shock when installation personnel from installing fluorescent lamp.When the two ends lamp holder all snaps in fluorescent lamp base, by the rotation to the LED fluorescent-lamp tube make the spacing fixture block 11 of king light head spare 1 cross in the triangular groove 50 clamping part 501 and with this clamping part 501 buckle mutually, at this moment, sheet metal 30 on spring probe 60 and the spring mountings 3 is conducted, thereby make power turn-on, light the LED fluorescent lamp; When taking off the LED fluorescent lamp, described spring 4 will reset, and described spacing fixture block 11 will be got back to limited mouth 500 along guide ramp 502, at this moment, spring probe 60 is separated with sheet metal 30 on the spring mountings 3, has stopped the electric shock hidden danger that may occur when installing once more thereby recover power down function.
