Description of the Invention: [Technical Field] The present invention is directed to a common connection device, and more particularly to a common connection device that can be inserted into a circuit board of at least two different widths and has good compatibility. [Prior Art] A liquid crystal display device (Liquid Qystai Display (LCD)) is a non-illuminating display device, and it is necessary to use a t light source to achieve the display function. The backlight usually has a cold cathode lamp (CCFL) ^ (External Electrode P - P ' EEFL), a light emitting diode (LED), and an electroluminescent sheet (el). In terms of application range, the light-emitting diode and the electro-excitation film are mainly used for backlights of liquid crystal display of small-sized, monochromatic light, such as mobile phones, PDAs, game machines, and the like. Large-size and high-brightness backlights mainly use cold cathode fluorescent lamps, such as monitors, LCD TVs, etc., because cold cathode fluorescent lamps have the advantages of stable oxygen and optical properties, long life, shock and impact resistance. Therefore, the cold cathode fluorescent lamp is the most suitable backlight for the current large-size liquid crystal display device. Since the cold cathode fluorescent lamp requires a higher voltage at startup, an appropriate power supply is required. At present, there are mainly two power supply solutions. The first solution is a 24V backlight mode, in which a converter is used to convert a DC voltage signal provided by a power supply (PowerSupply) into a high-frequency high-voltage pulse for lighting the backlight. a cold cathode fluorescent lamp in the module to provide the brightness required for the liquid crystal display device; the second solution is a two-in-one method in which an AC/DC (AC to DC) power supply and a DC/AC converter are integrated. Together, the LCD Integrated Power Supply (LIPS) can directly output high voltage to the cold cathode fluorescent lamp. Both the converter and the integrated power supply can be connected to the cold cathode fluorescent lamp by means of a connector to provide a stable voltage to the liquid crystal display device. Usually, the number of connectors required for different sizes of liquid crystal display devices is different. For example, a 42-inch LCD TV requires 14 to 28 connectors, a 37-inch LCD TV requires 6 to 12 connectors, and a 32-inch LCD TV. 4 to 8 connectors are required. 201019545 Drive Voltage Although the above two power supply solutions have their own advantages and disadvantages, it does not rule out the possibility of realizing the common use of the same backlight module or even the power supply design of the same liquid crystal display device in the future. Therefore, in order to realize the versatility of the converter and the integrated power supply, it is necessary to change the structure of the connector to selectively connect the circuit board provided with the converter or the integrated power supply according to different power supply requirements. The invention aims to provide a cold-fluorescent lamp.

The plug σ 10 and a second plug interface 12, wherein the first plug interface ίο Used for the -first-board 6 (this element can be seen with reference to the second a_); the second plug 12 is stacked above the first-plug interface 10 along the height direction of the connector i, For a second circuit board 7 (this element can be seen in Figure 3A). - The first guiding member 2, the third second guiding member 3 and the two third guiding members 4 are symmetrically disposed on the substrate 5 and located on both sides of the connector turns. From the schematic diagram of the positional relationship of the side of the first-B-shower, the two first-guide members 2 are located on both sides of the first plug-in interface ι of the connector i and the distance between the two first-guide members 2 D1 is equal to the width wi of the first circuit board 6 (the reference wi is seen in the second A picture) for guiding the first circuit board 6 into the first plug interface 10 of the connection w, and the second guide member 3 The two third guiding members 4 are respectively connected to the corresponding two first guiding members 2 and located on two sides of the second insertion interface 12 of the connectors i, between the two second guiding members 3 The distance D2 is greater than the distance m between the two first guiding members 2, and is equal to the width W2 of the second circuit board 7 (the symbol W2 is seen in the third A picture) for guiding the second circuit board 7 to be inserted into the The second plug connector 12 of the connector 1 is. The second guiding member 4 is configured to connect the corresponding first guiding member 2 and the second guiding member 3, and can guide the second circuit board 7 to insert the second insertion interface together with the two second guiding members 3. 12 in. In this embodiment, the substrate 5 is a metal back plate of the backlight module, and the first guiding member 2, the second guiding member 3 and the third guiding member 4 are formed on the substrate 5 via a stamping process. In the upper one, the first guide member 2 is vertically connected to the substrate 5 and extends in the height direction of the connector 1. The third guiding member 4 is vertically connected to the first guiding member 2, and extends in a direction away from the connecting direction in the width direction of the first circuit board 6. The third guiding member 4 is flush with the inner bottom surface (3) of the second connection 〇 π of the connection H 1 to carry and guide the second circuit board 7 to be inserted into the second insertion interface 12. The second guiding member 3 is vertically connected to the third guiding member 4 and extends in the height direction of the connector. - In the present embodiment, the first bottom surface of the connector i of the connector i mounted on the substrate 5 is higher than the surface 50 of the substrate 5, so that the first circuit board 6 needs to be inserted into the first plug-in interface. At 1 ,, it is difficult to align the first-plug connector 10, so the common connecting device of this embodiment should also include the -201091545 four guiding member 9, which is guided together with the two first guiding members 2 The first circuit board 6 is inserted into the first plug-in π 1G. In the present embodiment, the fourth guiding member 9 is preferably a plurality of bosses disposed on the substrate 5, and the bosses b are adjacent to each connector. The top surface of the boss is flush with the inner bottom surface 100 of the first plug-in interface 10 of the connector 1, that is, the height of the boss is equal to the inner bottom surface of the first plug connector 10 and the surface of the substrate 5 is Φ. The height of 50 is to carry and guide the first circuit board 6 to be accurately inserted into the first plug connector 1 , and the fourth guide member 9 is not limited to the above-mentioned boss, as long as it can be connected to the above-mentioned bearing and guiding functions. Anyone can. Referring to the second A ® and the second B ® at the same time, the first circuit board 6 includes a plurality of insertion ends 60, because the width Wi of the first circuit board 6 is equal to the distance between the two first guiding members 2.
