It should be noted that in the prior art of assembling the backlight module 2 of the present embodiment, it is only necessary to insert the lamp holder 230 #electrode terminal 232 into the carding space 244d of the lamp tube clamping portion μ4, and it will be embedded. The terminal terminal 212 is detached from the terminal fitting portion 242 ′ so that the electrode terminal Μ 2 of the lamp tube 23 电 is electrically connected to the embedded terminal 212 of the inverter circuit board 21 藉 by the lamp tube clamping member 24 . The backlight module 2 (8) of the present embodiment is easy to assemble, so the assembler can shorten the modification on November 20, 1995, and is not used in the assembly process of the backlight module 200. The method is therefore not a problem of poor soldering. In addition, the lamp clamping member 240 replaces the wiring and connectors in the prior art, which not only saves the material cost of the wiring and the connector, but also reduces the volume of the backlight module 200. The surname Figure 2 shows a schematic diagram of a liquid crystal display device made by using the backlight module of Fig. 2 . Referring to FIG. 2A, the backlight module 2 of the present embodiment can be applied to a liquid crystal display device 400 to shorten the overall assembly man-hour of the liquid crystal display device 4 and reduce the production cost thereof. The liquid crystal display device 400 includes the backlight module 200 and a liquid crystal display panel 300 described above. In the liquid crystal display, the board 300 is disposed on the backlight module, and the field crystal display panel is a transmissive liquid crystal display panel or a transflective liquid crystal display panel. In this embodiment, the lamp clip is The holding member 24 is a member of the optical module 200, and the lamp holding member 24 is for holding the electrode terminal 232 of the lamp holder 230 and the embedded antenna 212 for fitting the inverter circuit board 21. However, the tube clamping member 24 is not limited to being clamped only; the electrode terminal 232 is embedded in the embedded terminal 212. The tube clamping element 24 can also be used for other purposes. For example, the lamp female component 24 can be used in products such as mobile phones or computer motherboards to electrically connect terminals of different components. The lamp (4) component (4) is used, and the circuit of the component is not required to be electrically connected by soldering in the manufacturing process of the product. Therefore, the production cost can be reduced and the manufacture of the product can be shortened. In addition, the principle of the lamp clamping element clamping the assembly member is not 12 1322305. The modification of the claim on November 20, 1995 is limited to the above embodiment, and may be other mechanical principles, as long as - can be implemented And it can be electrically connected to different assembled components. FIG. 3 is a schematic structural view of a backlight module according to another embodiment of the present invention. Referring to FIG. 3, the backlight module 5 of the present embodiment is similar to the backlight module 200 of the above embodiment, except that the lamp tube 530 of the backlight module is a linear lamp. A plurality of lamp holding members 24 are disposed adjacent to opposite end portions of the bottom plate of the back frame 220 so that the lamp holding portion 244 can hold the electrode terminals at both ends of the lamp tube 530. In addition, in order to match the lamp tube clamping element 240 in the vicinity of opposite end portions of the bottom plate of the back frame 220, the plurality of embedded terminals 512 of the inverter circuit board 510 are arranged corresponding to the lamp tube clamping member 24〇. The side of the inverter circuit board 510 facing the back frame is such that the dormant terminal 512 can be embedded in the terminal embedding portion 242 of the lamp tube clamping member 240, respectively. It is worth noting that since the backlight module 500 uses the lamp tube clamping member 240 as an assembly member, it also has the same advantages as the backlight module 2〇〇. The backlight module 500 can also be applied to a liquid crystal display device (not shown) to shorten the overall assembly man-hour of the liquid crystal display device and reduce the production cost thereof. In summary, the backlight module and the liquid crystal display device holding component of the present invention have at least the following advantages: 2. The lamp tube holding component proposed by the present invention is easy to be connected with the inverter-circuit board and the drum-in terminal and the lamp. When the electrode terminals of the tube are assembled, when used as an assembly member of the backlight module, the assembly man-hour of the backlight module can be shortened and the cost of production can be reduced. In addition, the lamp element can be used for other purposes, so that the terminals of different components do not need or omit the branches by the tan
