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 electrical and optical properties stability, long life, shock resistance, and impact resistance. Cold cathode fluorescent lamps are the most suitable backlights for large-size liquid crystal display devices. Since the cold cathode fluorescent lamp requires a higher voltage at startup, an appropriate power supply is required. At present, there are two main power supply solutions 'the first type of system; 24V backlight mode, which uses a conversion φ device to convert the DC voltage signal provided by the power supply (powerSupply) into a high-frequency high-voltage pulse, used to illuminate the backlight mode. Cold cathode fluorescent lamps in the group to provide the brightness required for liquid crystal display devices; the second solution is a two-in-one method that integrates an AC/DC (AC to DC) power supply and a DC/AC converter The integrated power supply (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. [si 5 1354411 Although the above two power supply solutions are all right-hand modules or even the same - the current display of the liquid crystal display device in the same backlight in order to implement the converter and the integrated Wei supplier, so the 'required change' The structure of the connector, the choice of the electric power is not enough, _ the circuit board with the converter type power supply is inserted into the remote technology crying ^_ # 1 electric tower pole h罝 hundred whole drive electric What? _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In accordance with the above object of the present invention, the present invention provides a common connection port for at least two circuit boards having unique widths to be inserted. : at least - a connector, two first guides and two second guides.

In this embodiment, the inner bottom surface of one of the first plug connectors 1 of the connector 1 mounted on the substrate 5 is higher than the surface 50 of the substrate 5, so when the first circuit board 6 needs to be inserted into the first plug interface 1〇 In this case, the first insertion interface 10 is not easy to be aligned. Therefore, the common connection device of the embodiment should also include a 1354411 four guide member 9 that guides the first guide member 2 together with the first guide member 2 The circuit board 6 is inserted into the first plug connector 10. In this embodiment, the fourth guiding member 9 is preferably a plurality of bosses disposed on the substrate 5, the bosses are adjacent to each of the connector jaws, and the top surface of the boss is 9 The inner surface of the first plug-in interface 10 of the connector 1 is 1 〇〇, that is, the height of the boss is equal to the height of the inner bottom surface of the first plug connector 10 from the surface of the substrate 5 to carry and guide the first A circuit board 6 is accurately inserted into the first-plug connector 10 t, and the fourth conductive member 9 is not limited to the above-described bosses, as long as it can achieve the functions of carrying and guiding the above. Referring to the second A and second B diagrams, the first circuit board 6 includes a plurality of insertions = 60, because the width W1 of the first circuit board 6 is equal to the distance between the two first guides 〇 ι, when the insertion end 60 of the first circuit board 6 needs to be inserted into the first plug interface 1 ,, firstly, the first guide member 2 can be used to stop the misalignment of the _ plate 6 in the left and right direction.
