Embodiment
The effect of the utility model fluorescent tube holder is, fluorescent tube is fixed on the desired location in the back light unit, so that the light that each fluorescent tube sent can cooperate the mechanicalness spatial design of back light unit and backlight is provided.For reaching this purpose, if with the luminous direction of back light unit is reference direction, fluorescent tube holder of the present utility model spatially is fixed in itself on the base of back light unit in luminous updrift side exactly, also is used for simultaneously fluorescent tube is fixed in desired location on the luminous downstream direction.On the other hand, in the mechanicalness location, the utility model fluorescent tube holder also needs the fluorescent tube of its fixing is provided the effect of electrically conducting of lamp power supply simultaneously.
While can be easier to understand the structure of the utility model fluorescent tube holder with reference to figure 1 and Fig. 2.Wherein Fig. 1 is the stereographic map of the utility model fluorescent tube holder one preferred embodiment, and Fig. 2 then is the end-view of Fig. 1 fluorescent tube holder embodiment along its fluorescent tube axis direction.
Be the fluorescent tube 170 of back light unit with the shown part of dotted line among Fig. 1 and Fig. 2, the two ends that it is positioned at the canals of stilling 172 of main fluorescent tube length respectively utilize the electrode cap 174 of a conductive metallic material made to be coated.The electrode cap 174 at each tubes two ends all utilizes fluorescent tube holder of the present utility model to provide the power supply of mechanical space orientation and electric property to supply with simultaneously in the back light unit.
According to a preferred embodiment of the present utility model, as shown in Figures 1 and 2, fluorescent tube holder 100 have a pedestal 110 that is roughly solid rectangle with and the fluorescent tube fixing folder 120 of top.Holder pedestal 110 is as the support of fluorescent tube fixing folder 120, is supported in setting height on the circuit board of being installed on the back light unit base 160 (representing with schematic dotted line among the figure) in order to the fluorescent tube with 120 clampings of fixing folder.On the other hand, fixing folder 120 is in order to the clipping fluorescent tube, fluorescent tube is fixed on the position location in the back light unit.
Two fluorescent tube retaining sheets 122 and a preferred embodiment of 124 are known demonstration as Fig. 2, and each is perpendicular on the tangent plane of the long axis direction of fluorescent tube, have the center of circle towards its institute cambered surface pinch 123 and 125 at the fluorescent tube center of clipping jointly.In a preferred embodiment, the surperficial radian of two cambered surface pinch 123 and each arc-shaped inner surface of 125 and lamp tube electrode cap 174 coincide, and in other words, both have essentially identical radian.Like this, when fluorescent tube 170 dotted arrow direction in figure is depressed and is installed on the position location in the fluorescent tube holder 100, two fluorescent tube retaining sheets 122 and 124 cambered surface pinch 123 and 125 whole inner cambered surface just can be coincide mutually with the corresponding arc-shaped surface of lamp tube electrode cap 174, think the electric conductivity that provides best between the two.
Two fluorescent tube retaining sheets 122 and 124 respectively have a stop part 127 and 129 along the fluorescent tube axis direction respectively near the part of fluorescent tube tail end.Two fluorescent tube tail end stop parts have the sweep of charging into towards the fluorescent tube center, when being installed in the utility model fluorescent tube holder at fluorescent tube, and the location that can on the axis direction of fluorescent tube, limit fluorescent tube.
Owing to must keep good electrical conductivity between lamp tube electrode cap 174 and the fluorescent tube holder of the present utility model, so fixing presss from both sides 120 two fluorescent tube retaining sheets 122 and the 124 lamp tube electrode caps 174 to its clipping enough mechanical clipping power must be provided.In practical situations, for good between the fluorescent tube 170 of guaranteeing fluorescent tube holder 100 and its clipping electrically contacts, before fluorescent tube is installed on the holder, on two fluorescent tube retaining sheets 122 of fluorescent tube holder 100 and 124 the surface, and on the surface of the electrode cap 174 of fluorescent tube, or both one of them, can apply conducting resinl in advance with conduction property.The conducting resinl that is fit to can comprise such as the heat curing-type conducting resinl that contains suitably a small amount of silver powder.
In a foundation preferred embodiment of the present utility model, the fluorescent tube fixing folder 120 of fluorescent tube holder 100 can utilize the technology of mechanical stamping by the sheet metal of single suitable material and make moulding.The fluorescent tube fixing of this conductive metallic material folder 120 can utilize following institute that the mode that illustrates is installed on the pedestal 110.
According in the fluorescent tube holder 100 of the present utility model, a preferred embodiment of its pedestal 110 as previously mentioned, is the structure of solid rectangle roughly, its in order to support fixing folder 120 and with the fixing clamping due to its top, know as each figure in the accompanying drawing to manifest.The essentially rectangular body top of pedestal 110 has two fixings folder fixed hook 112 and 114.As shown in Figures 1 and 2, fixing folder fixed hook 112 and 114 respectively has the teat that extends towards pedestal 110 body interior, it stretches into two fluorescent tube retaining sheets 122 of fixing folder 120 and the opening on 124 sidewalls after fixing folder 120 is installed in the position location, and catch on the base plate 121 of fixing folder 120, with both are colluded mutually solid together.
On the other hand,, utilize and fixing folder fixed hook 112 and 114 same or analogous modes, also can have two circuit board fixed hooks 116 and 118 in the bottom of pedestal 110.As shown in Figure 2, circuit board fixed hook 116 and 118 respectively has the teat that extends towards pedestal 110 body interior, it is after whole fluorescent tube holder 100 is installed in position location on the circuit board 160, can stretch into the opening of being offered on the circuit board 160, and catch on the lower surface of circuit board 160, so that whole fluorescent tube holder 100 is fixed on the circuit board 160.
In according to of the present utility model one preferred enforcement, fixing folder 120 can respectively have a tube power contact pin 126 and 128 at it along the two ends on the fluorescent tube long axis direction, and 110 of pedestals can have two corresponding power supply contact pin and connect the hole.When fixing folder 120 and pedestal 110 are assembled together when forming complete fluorescent tube holder 100 as shown in Figures 1 and 2, the corresponding power contact pin that the tube power contact pin 126 and 128 of fixing folder 120 just can be passed pedestal 110 connects the hole, and is exposed to beyond the lower surface of pedestal 110.As shown in Figure 2, the length that tube power contact pin 126 and 128 exposes should be enough to pass the basal surface of circuit board 160, and outstanding suitable length, is beneficial to carry out soft soldering.
Understandable as those skilled in the art institute, the tube power contact pin 126 and 128 of fixing folder 120 by soft soldering on circuit board 160, not only can mechanically fluorescent tube holder 100 of the present utility model be fixed on the position location, also can provide simultaneously electrically continuing of fixing folder 120, to provide power supply to the fluorescent tube that is installed in the fluorescent tube holder 100.
In according to of the present utility model one preferred enforcement, pedestal 110 can utilize plastic material to make in a large number to advance such as the technology of ejection formation cheaply.
Though the utility model conjunction with figs. illustrates as above that with preferred embodiment so it is not in order to limit the utility model.Those skilled in the art can carry out all kinds of changes and variation under the situation that does not break away from the utility model design scope, therefore protection domain of the present utility model is when being as the criterion with the scope that accompanying claims were defined.
