The specific embodiment
Please refer to accompanying drawing and understand the down straight aphototropism mode set of one embodiment of the present invention; It comprises a kind of lamp socket with mutual locking structure, can be so that fluorescent tube and inverter when inserting this lamp socket simultaneously, make the lamp socket two ends more firm to the clamping of fluorescent tube and inverter; And the metal collar is set on the electrode contact of this fluorescent tube and inverter; Increased the clamping area, effectively avoided having increased the service life of module backlight because of plug or the loosening spark phenomenon that produces.
Shown in Figure 2 is the schematic perspective view of lamp socket in the down straight aphototropism mode set of one embodiment of the present invention.This lamp socket 20 has shell 200, first sheet metal 211 and second sheet metal 212.First sheet metal, 211 types of having " bow " word shape structure; Second sheet metal 212 has instead " bow " word shape structure; This first sheet metal 211 and second sheet metal 212 are arranged in this shell 200; Their both ends form first clamping part 210, and an other end forms the second clamping part (not shown).Be provided with first brace 231 that points to said second sheet metal 212 at the middle part of said first sheet metal 211; The middle part of said second sheet metal 212 is provided with second brace 232 that points to said first sheet metal 211; Said first brace 231 is hinged through fixed axis 203 with said second brace 232.Be provided with spacer 201 in the middle of the shell 200, which is provided with reference column 202, through with backboard on locating hole cooperate, can this lamp socket 20 be fixed on the backboard.203 pairs of fixed axis should be arranged on shell 200 inboards in spacer 201 positions.
Please in the lump with reference to figure 3, shown in Figure 3 be among Fig. 2 lamp socket along the generalized section of AA line.As shown in the figure; Also be provided with open splinter 213 to 215 at this first clamping part 210 near the place of opening; Become " v " font respectively like two open splinters 214,215 among Fig. 3; With so that this first clamping part 210 has the trend that extends out, its can be respectively on first sheet metal 211 and second sheet metal 212 punching press form, also can this two shell fragment be fixed on this first sheet metal 211 and second sheet metal 212 through welding.On this second clamping part 220, also be provided with banking stop 223; The one of which end is fixedly installed on first sheet metal 211 (or second sheet metal 212); The other end props up on second sheet metal 212 (or first sheet metal 211) movably, limits this second clamping part, 220 shrinkage amplitudes with this.Inboard at this shell 200; Also be provided with two locating pieces 205; These two locating pieces 205 prop up the middle part of first sheet metal 211 and second sheet metal 212; And cooperate first brace 231, second brace 232, making win clamping part 210 and second clamping part 220 is moving fulcrum with the middle part of first sheet metal 211 or second sheet metal 212.When this first clamping part 210 extends out, be passed to second clamping part 220 and make its contraction through first brace 231, second brace 232; When deserving this second clamping part 220 when extending out, be passed to first clamping part 210 and it is shunk through first brace 231, second brace 232, realize tight purpose mutually with this.
Please again with reference to figure 4 and Fig. 5, Fig. 4 and Fig. 5 are respectively fluorescent tube and the sketch map of inverter in the down straight aphototropism mode set of one embodiment of the present invention.As shown in the figure, an end of fluorescent tube 300 has electrode leads to client 301, is provided with metallic sheath ring 310 in the periphery of this electrode 301, and this metal collar 310 keeps electrically contacting with this electrode 301.Inverter 400 has a plurality of connecting portions, has the electrode tip 401 of conducting function on it, is provided with metallic sheath ring 410 in the periphery of this electrode tip 401, and this metal collar 410 keeps electrically contacting with this electrode 401.Should be pointed out that in diagram of the present invention the metal collar 310 is respectively annulus and semicircular ring with the metal collar 410, but in practical application, this cover is bad equally can be for square sleeve ring, triangle collar or the like, not as limit.
Please again with reference to figure 6, Fig. 6 is the stressed sketch map of lamp socket 20 after inserting fluorescent tube and inverter among Fig. 2.In the present invention; The metal collar 310 of fluorescent tube is interspersed in first clamping part 210; The metal collar 410 of inverter is interspersed in second clamping part 220, but in practical application the position of this first clamping part 210 of interchangeable and second clamping part 220, do not influence enforcement of the present invention.Usually the volume of this fluorescent tube metal collar 310 and the inverter collar 410 is a bit larger tham the grasping part of first clamping part 210 and second clamping part 220.Represent the influence of 310 pairs of these lamp sockets of the fluorescent tube metal collar among the figure with block arrows, hollow arrow is represented the influence of 410 pairs of these lamp sockets of the inverter metal collar.
After this fluorescent tube metal collar 310 inserts first grasping part 210; Make this first clamping part 210 have the trend that extends out; But under the restriction of brace 230 and locating piece 205; Two metal sheets is a fulcrum with the middle part, makes second clamping part 220 have the trend of contraction, thereby the inverter metal collar 410 in second clamping part 220 is played the effect of clamping.Same principle after the inverter metal collar 410 inserts second clamping part 220, makes this first clamping part 210 shrink, and plays the purpose that clamps the fluorescent tube metal collar 310.Realized that with this this lamp socket is to firm clampings such as fluorescent tube and inverters.
In sum; The present invention is through a kind of new lamp socket of design; Solved fluorescent tube and the fixing not firm problem of inverter in the prior art, through link the metal collar has been set simultaneously, increased contact area with lamp socket at fluorescent tube and inverter; Avoid in the plug process, producing bad phenomenon such as sparking, prolonged the service life of this kind module backlight.
By the detailed description of the above preferable specific embodiment, hope can be known description characteristic of the present invention and spirit more, and is not to come claim scope of the present invention is limited with the above-mentioned preferable specific embodiment that is disclosed.On the contrary, its objective is that hope can contain in the scope of claim of being arranged in of various changes and tool equality institute of the present invention desire application.
