Description of the Invention: [Technical Field of the Invention] Field of the Invention 5 ❹ 10 15 ❹ 20 [0001] The present invention relates to a power supply terminal and the like, and more particularly to a connection for mounting a cold cathode discharge lamp to, for example, a backlight unit. Power supply terminal. BACKGROUND OF THE INVENTION [0002] A cold cathode fluorescent lamp, which is a cold cathode fluorescent lamp, is suitable for a thinner diameter, and is therefore suitable as a light source of a backlight unit which is required to be thinned (small size). In order to mount the cold cathode fluorescent lamp in the backlight unit and to electrically connect the wires between the ends of the cold cathode glory lamp and the lighting power supply, power supply terminals are provided at both ends of the cold cathode fluorescent lamp. [0003] The power supply terminal is composed of a cylindrical body portion and a wire connecting portion extending from the body portion. The body portion is externally inserted into the end portion of the hermetically sealed glass tube in the cold cathode fluorescent lamp. The wire connection portion is electrically connected to the aforementioned wire. [0004] When the power supply terminal having the above-described configuration is used, by attaching the main body portion of the power supply terminal to the connector provided in the backlight unit, the cold cathode fluorescent lamp can be mounted on the backlight unit by one-touch. Power from the lighting power source can be made via the connector and the power supply terminal. Here, the wire connecting portion in the power supply terminal is not particularly necessary, and it is an extremely important part to reliably input electric power from the lighting power source to the cold cathode fluorescent lamp, and various structures have been conventionally proposed. [0006] For example, Patent Document 1 discloses that a rectangular connecting piece end portion extending in the tube axis direction of the glass tube is folded at a right angle by a main body portion of 3 200934983, and is disposed at the folded portion. Insert the through hole of the wire. And in a state in which the wire is inserted into the insertion hole, the solder flows into the gap between the wire and the insertion hole to electrically connect the two. [0007] Thereby, the wire and the connecting piece are reliably electrically connected via the solder. Patent Document 1: Japanese Laid-Open Patent Publication No. Hei 2-7-234551 C. Inventive Disclosure 3 Disclosure of the Invention [0008] However, although the solder has a function as a joint member, its mechanical strength is generally It is lower. Therefore, for example, when an external force is applied to the main body portion in the direction of the tube axis, the solder is peeled off from the member on the side thereof, and the solder itself is broken, so that the wire and the connecting piece 15 cannot be obtained. [0_ To deal with this problem] It is conceivable to form the front end portion of the connecting piece into an appropriate shape and crimp the front end portion to the wire, but it is expected that excessive force is applied to the wire when the crimping is applied (wire The force in the direction of the diameter), and: The cracking (damage) of the glass tube portion of the wire is separated. [20] The present invention has been made in view of the above problems, and aims to provide a power supply terminal and a cold cathode discharge lamp having the same, and the power supply terminal can secure the wire and the wire as much as possible. When the 9 ^ is connected and set in the cold cathode discharge lamp, the glass can be prevented. 200934983 The means for solving the problem is to put the snow into the snow ^ ^ ^ ^, the power supply terminal of the present invention is installed in the cold The second cold cathode discharge lamp comprises a tubular glass ribbon for sealing to the end of the glass container and to the outside of the tube axis: and the power supply terminal comprises: a body portion, The outer periphery of the end of the glass container is externally inserted and the elastic holding portion is provided in the above, and the wire is held by the elastic force in a state in which the wire is inserted. Further, the elastic holding portion includes the body The two elastic piece portions extending from 1 to J and the abutting portions provided at the ends 4 of the respective elastic piece portions and abutting against the other wire are in the state before the insertion of the wire 2 The imaginary outer surface of the wire is more In the direction of the inner side, a contact portion of the abutting portion that abuts against the lead wire is present. ^ [3] or the body portion is formed in a cylindrical shape, and the elastic grip portion 15 is extended by the body portion. And a cone portion having at least two slits that are openly disposed in a tube axis direction, and an abutting portion provided at a rigid end of the cone portion and abutting against a peripheral surface of the wire, a taper thread is provided in a portion of the outer surface of the circular body P, and the power supply terminal further includes a ring nut that is screwed to the taper screw. 2〇^ [〇〇14] Further, in the abutting portion The abutting portion is formed in a shape that fits the outer peripheral surface of the V-line, and is in surface contact with the outer circumference of the wire. [0015] Further, in a state in which the wire is inserted into the elastic holding portion, the aforementioned resilience is used The abutting portion presses the wire with a pressing force of at least 100 [gq or more. 5 200934983 [0016] To achieve the foregoing object, the cold cathode discharge lamp of the present invention comprises a tubular glass container, and is sealed to the glass container. End and toward the tube axis a cold cathode discharge lamp with a power supply terminal, wherein the power supply terminal is disposed at an end of the glass container, and the power supply terminal of the power supply terminal 5 is externally inserted, and the body portion is externally inserted In the outer periphery of the end portion of the glass container, the wire is inserted into a separate elastic holding portion.

Advantageous Effects of Invention [0019] According to the power supply terminal having the above-described configuration, a wire is inserted into the elastic cymbal portion, and the wire can be electrically connected by holding the wire by a repulsive force. Therefore, the above problems caused by solder or the like in order to obtain electrical connection between the two are less likely to occur. Therefore, electrical connection can be reliably performed. Further, since the wire can be held by the elastic holding portion by the insertion, when the power supply terminal is mounted on the cold cathode discharge lamp, it is not easy to apply an excessive force to the wire. Therefore, when it is placed in a cold cathode discharge lamp, damage to the glass tube can be prevented.

[Embodiment 2] The best mode for carrying out the invention [0023] Hereinafter, embodiments of the invention will be described with reference to the drawings. <Embodiment 1> Fig. 1 is a partial cut perspective showing a schematic configuration of a power supply terminal 2 of the first embodiment and a cold cathode fluorescent lamp 4 provided at both ends of the power supply terminal 2 200934983

In all the figures, the scales between the constituent members are not the same. The cold cathode fluorescent lamp 4 has a glass container 6 having a circular cross section. The glass container 6 is shielded from the glass, and (4) the Neuss wire is a container formed by hermetic sealing. Further, the straight tube shape ' may be a curved shape such as a U-shaped tubular shape, a spiral tube shape or the like. The glass container 6 is not limited to the illustrated example, the 3-shaped tubular shape, the S-shaped tubular shape, the W 3 and the 'glass container (glass tube) ❹ 10 15 Ο 20 The cross section is not limited to a circular shape, and may be an oval shape. Flat shape such as. The glass container 6 is formed of borosilicate glass for tungsten wire sealing. When the display size is one example, the total length is 73 〇 [mm], the outer diameter is 4 [mm], and the inner diameter is 3 [mm]. Further, the material of the glass container 6 is not limited to borosilicate glass, and may be lead glass, lead-free glass, soda lime glass, and other soft glass. [0026] Inside the glass container 6, a mixture of no and argon of about 8 [kPa] (20 [t]) as a noble gas with mercury (not shown) and a rare gas is used as Ne: The ratio of 95 [mol%], Ar: 5 [mol%] was sealed. Also, rare gases may be free of helium. At this time, infrared radiation of the cold cathode discharge lamp can be suppressed. Further, it is preferable to contain ruthenium in a range of 〇5 [m〇1%] or more and 5 [mol%] or less in the rare gas. At this time, the lamp voltage does not largely change, and the infrared radiation of the cold cathode discharge lamp can be suppressed. For example, if the wind is in the range of 0 [mol%] or more and 9.5 [mol%] or less, the range of 氖 is 90 [mol%] or more and 95.5 [mol%] or less, and 氪 is 〇.5 [m〇 I〇/0] is above and below 5 [mol%]. Further, it is more preferable to contain ruthenium in a range of 〇_5 [mol%] or more and 3 [mol 〇 / 〇] or less in a rare gas. Further, it is more preferable to include 氪 in the range of 1 [m〇l%] or more and 3 [m〇i%] or less in the rare gas. [0027] Further, a phosphor film 8 is formed on the inner surface of the glass container 6. The glory body film 8 contains three kinds of rare earth-based phosphors of blue (B), green (G), and red (R), and emits white light as a whole. In this example, a blue phosphor is used to activate barium aluminate 5 money [BaMg2A1i6〇27: Eu2+] (abbreviation: BAM-B), and a green phosphor is used to co-activate barium phosphate [LaP〇4: Ce3+, Tb3+] (abbreviation: LAp), used in red phosphors to activate yttrium oxide [Y2〇3: Eu3+] (abbreviation: γ〇χ). [0028] The wire 10 is an internal wire 丨〇α formed of tungsten and an external wire 10 形 formed of nickel. The wire 1 is internally sealed, the portion of the wire is sealed at the end of the glass container 6, and the outer wire 10B is extended outwardly from the sealing portion in the direction of the tube axis. The inner lead 10A and the outer lead 1〇B each have a circular cross section. For example, the inner wire 10 has a wire diameter of 0 8 [mm] and a total length of 3 [mm]. The outer wire 10B has a wire diameter of 〇.6 [mm] and a total length of 4 [mm]. Further, when the glass container 6 is a borosilicate glass for iron-nickel-cobalt wire sealing, the inner wire 15 is preferably composed of iron and an alloy (iron-nickel-cobalt alloy) or molybdenum. Further, when the glass container 6 is lead-free glass or soda lime glass, the inner lead 1A is preferably composed of an alloy of iron and nickel or a copper-clad nickel wire. [0029] The inner side end portion of the glass container 6 sealed in the inner lead wire 1A of the end portion of the glass container 6 is joined to the electrode 12 by laser welding or the like. The electric pole 12 is a bottomed cylindrical shape, that is, a so-called hollow type electrode, and is a worker who performs the boring bar. As the electrode 12, a hollow type electrode system is used to effectively suppress sputtering in the electrode which is caused by discharge in the lighting of the lamp tube (for details, refer to Japanese Laid-Open Patent Publication No. 2002-289138). Further, the material which can be used for the electrode 12 is not limited to a pry bar, and may be, for example, nickel, a button, molybdenum, tungsten or the like. Further, the 200912983 electrode 12 and the inner lead 10A can be welded via solder such as a nickel foil or an iron-nickel-cobalt alloy foil. The surface of the electrode 12 may also form an electron radioactive material layer (not shown). At this time, the lamp voltage can be lowered 5 compared to the lamp tube in which the electron radioactive material layer is not provided. Further, by providing the power supply terminal 2 to be described later, heat generated by the electrode 12 can be easily dissipated by the power supply terminal 2, so that the temperature around the electrode 12 can be prevented from excessively rising, and mercury suppression can be prevented around the electrode 12. Since it is less, sputtering of the electron radioactive substance layer can be suppressed, and the effect of lowering the voltage of the lamp can be maintained for 10 times as compared with the case where the lamp tube of the power supply terminal 2 is not provided. Specifically, the layer of the electron radioactive material is formed inside the electrode, for example. The layer of electron radioactive material contains, for example, a rare earth element. In the cold cathode - discharge lamp, the lamp voltage can be effectively reduced. Further, the rare earth element is more preferably any one of lanthanum (La) and yttrium (Y). 15 [0031] The electron radioactive material layer further comprises bismuth (Si), aluminum (A1), zirconium oxide (Zr), boron (B), zinc (Zn), bismuth (Bi), phosphorus (P) and tin (Sn). In the middle of the term - more than one. At this time, the reduction of the lamp voltage can be further sustained. Further, a planer (Cs) compound may be contained in the electron radioactive material layer. At this time, the dark start characteristic of the lamp can be further raised. Further, the compound 20 may be attached to the inner surface and the outer surface of the electrode 12 separately from the electron radioactive material layer. Further, it is preferable to use one or more of a planing compound such as barium sulfate, barium aluminate, barium acid, barium tungstate, barium molybdate and chlorination. [0033] The power supply terminal 2 is attached to the end of the glass container 6. 11 200934983 5 [View] in Figure 3 (8) shows a perspective view of the power supply terminal 2 installed in front of the glass container 6, the power supply terminal after the installation of the fourth object (4), and the third (4) diagram illustrates the migration end portion of the clip (4) The figure of the gap W between the outer surface of the main body part and the outer surface of the glass container 6 is shown in the figure of the gap W of the part other than the main-body part of the glass container 6. The power supply terminal 2 includes a body portion 6' which is externally inserted into the outer periphery of the end portion of the glass container 6, and an elastic member which is extended from the original portion 6 and which is held by the conductor _ (external wire 1B). In the case where the stainless steel is used for the press-fitting process (sheet metal processing), it is preferable to use SUS3〇4 from the viewpoint of corrosion resistance and elasticity. Oh, not limited to not recording steel,

Other metal materials such as copper, spring steel, and tantalum steel can also be used. 15 20 [0036] The body portion is cylindrical. The wall portion of the main body portion 16 is formed at two intervals in the circumferential direction 4 to form the nip portion 2 〇. Each of the caliper portions 2 is formed by a tongue which is formed by cutting a substantially U-shaped slit in the longitudinal direction with respect to the cylindrical wall. The distal end portion of the tongue piece that is separated from the main body portion is curved as shown in the drawing, and is bent toward the inner side to have a "&lt;" shape, and the base end portion directly connected to the main body portion 16 is The starting point is curved toward the inside as a whole (plastic deformation). When the main body portion 16 composed of the above-described configuration is externally inserted into the outer periphery of the end portion of the glass container 6, the top of the "&lt;" word of the wandering end portion abuts on the outer periphery of the glass container 6, and the entire nip portion 20 is attached. The base end portion is used as a base point to cause elastic deflection (elastic deformation) to the outer side in the radial direction of the bowl container 6, and the glass container 6 is held by the repulsive force. Thereby, the glass container 6 is positioned in the main body portion 16 in a state in which the cylindrical body portion 16 is aligned with the substantially axial center. 12 200934983 5 Ο 10 15 Lu 20 [0037] Further, it is needless to say that the shape, the number, the arrangement position, and the like of the caliper portion 20 are not limited to the above. Briefly, the glass container 6 may be elastically supported in the main body portion 16. The caliper portion is not limited to the nip portion 20' in the following direction, that is, as shown in Fig. 3(b), the base end portion of the tongue is located on the tube end side in the tube axis direction of the glass container 6, and the tongue The moving end portion is on the tube center side in the tube axis direction of the glass container 6, and may be the clip portion 20a in the following direction as shown in Fig. 4, that is, the base end portion of the tongue is in the glass container 6. The tube center side in the tube axis direction, and the tongue end portion of the tongue is in the tube end side in the direction of the rotation axis of the glass container 6, and further, the card holder in the direction shown in Fig. 3(b) The portion 20 is interlaced with the nip portion 2〇a in the direction shown in Fig. 4, and the nip portions in the two directions are mixed. Further, the contact portion of the glass container 6 with the nip portion 20 should be closer to the central portion side of the glass hopper 6 in the tube axis direction than the sealing portion of the glass container 6. At this time, the power supply terminal 2 can be attached to the glass container 6 in a stable state while avoiding the sealing portion whose shape is liable to become untwisted. Further, a gap is preferably provided between the wrap portion of the nip portion 20 and a portion other than the detachment portion 20 of the main body portion 6. At this time, when the power supply terminal 2 is transported or the like, the traveling end portion can be prevented from being caught by the main body portion 16. Further, as shown in Fig. 3(c), the gap S along the direction in which the tongue of the traveling end portion extends is preferably 〇.1 [mm] or more. More preferably, the gap & is in the range of [ 2 [mm]a and L 〇 [mm] or less. Further, as shown in Fig. 3(d), the gap S2 at which the tongue of the traverse of the traverse is extended and the end portion of the traverse is preferably 〇. 2 [mm] or more. More preferably, the gap & is in the range of 3.3 [mm] or more and i 〇 [mm] or less. Further, the width s3 of the gap portion 13 200934983 between the inner surface of the main body portion 16 and the outer surface of the glass container 6 is preferably o.1 [mm] or more. At this time, the glass container can be easily woven into the body portion 16. The width of the gap between the inner surface of the main body portion 16 and the outer surface of the glass container is S3 or more and 〇5 [awake] or less. Further, it is more desirable that the upper part is Q3 [m is called the following range. The two elastic piece portions having an elongated rectangular shape are extended from the body portion 16 such as the bucket portion, and the abutting portions 26, 28 are provided by the elastic piece portion. _39] Elastic W22, 24_ base (four) silk point, let the movement (four) 0 10 bend in the direction of the tube axis. [〇〇4〇] The abutting portions 26, 28 have an arc-shaped cross section, and the inner peripheral surface of the abutting portion that is in direct contact with the outer surface of the wire 〇 is formed to fit the outer peripheral surface of the wire 10. The shape of the shape is in surface contact with the surface of the wire (10) (4). 15 [〇〇41] Further, before the wire 10 is inserted between the two abutting portions 26, 28, the abutting portions 26, 28 are present on the imaginary outer peripheral surface of the wire 丨〇 (external wire 10B) indicated by a broken line. Closer to the inside of the radial direction. [0042] When the power supply terminal 2 composed of the above-described configuration is externally inserted into the cold cathode fluorescent lamp 4 from the side of the main body portion 16, as described above, the main body portion 16 is opposed to the glass by the function of the clip 20 portion 20. The container 6 is positioned relatively in the radial direction. Further, the elastic holding portion 18 is extended toward the outer side in the radial direction of the wire 10 with the insertion of the wire 1 (the outer wire 1B) and holds the wire 10 by its resilience. Thereby, the wire 1 is electrically connected to the elastic holding portion 18, and the wire 10 is electrically connected to the body portion 16. Further, the inner side of the elastic pieces 22, 24 also serves as a guide member for guiding the lead wires 10 to the abutting portions 26, 28 as 14 200934983, so that the front end portion of the wire 10 can be smoothly inserted between the abutting portions 26, 28. [0043] In this way, the wire 1 只需 can be electrically connected by inserting the wire 1 〇 with respect to the elastic clamping portion 1 , in the axial direction thereof, so that an excessive force is exerted on the wire 5 (with the axis of the wire 10 ) The force of the orthogonal direction). Therefore, it is possible to prevent damage to the portion of the glass container 6 holding the wire 10. Further, even if the force of the glass container 6 in the tube axis direction is applied to the power supply terminal 2, the elastic holding portion 18 (the abutting portions 26, 28) slides only in the tube axis direction, so that the stool can be maintained by returning to the original position. Electrical connection status. [0044] Further, the pressing force applied to the external lead wire 1B by the abutting portions 26, 28 is independent of the contact area, and if it is at least 100 [gf] or more, it can be confirmed that the flow point is endured. The free lamp current is 4 [mA] ~ 18 [mA] to the extent of cold ρ. The pole discharge lamp can achieve a good electrical connection. Regardless of the contact area, the contact form between the contact portion and the external lead may be a point contact, a line contact, or a surface contact, which is suitable for all of the power supply terminals of the embodiments described later. In this example, the pressing force (rebounding force) can be suitably adjusted by the material, shape ® (length, cross section) of the elastic piece portions 22, 24. [45] Here, the length L of the elastic grip portion 18 (the length along the tube axis of the glass unit 6) is preferably in the range of 1.5 [mm] to 7 [mm]. 20 [0〇46] Further, when any one of the abutting portions 26, 28 is detached from the wire 10 for some reason, the wire 1 is used as a fixed end of the sealing portion of the glass container 6, that is, a so-called cantilever beam . At this time, it has been experimentally found that when the bending moment in the fixed end portion of the wire 10 is 1.5 [kgf · mm] or less, the wire 1 〇 (the outer wire 1 (3 Β) Ι does not undergo plastic deformation. The experimenter is an external conductor composed of Ni (nickel) 15 200934983 having a diameter of 66 [mm]. Further, the diameter of the external conductor 10B is not limited to 〇.6 [mm], and may be the same as the foregoing embodiment. 〇.8[mm] 〇[0047] Further, as shown by the broken line in Fig. 3, when the power supply terminal 2 is attached to the glass container 6, the wire 10 (external wire 10B) may be provided to the abutting portion. Guide members 23, 25 of 26, 28. The guide members 23, 25 are located between the outer peripheral elastic pieces 22, 24 of the main body portion 16 and are close to the front end portion of the body portion 16 Further, in order to facilitate the relative positioning of the power supply terminal 2 in the axial direction of the tube 10 of the cold cathode discharge lamp 4, a stopper may be provided at the power supply terminal. [0049] The figure shows a part of the elastic piece 22 corresponding to the abutting portion 26 of the power supply terminal 2 provided with the stopper, Fig. 5(a) The front view is displayed, the fifth (b) shows the section AA in the 5th (a), and the 15th (c) shows the right side. Again, the dotted line shows the external conductor 1 〇B. In this example, the rectangular piece extended by the abutting portion 26 is bent at a right angle to form the stopper 30. [0051] Thus, 'the front end of the outer lead 10B abuts against the stopper 3' Simply inserting the power supply terminal 2 into the cold cathode fluorescent lamp 4 allows the power supply terminal 20 to be relatively positioned in the tube axis direction with respect to the cold cathode fluorescent lamp 4. Further, the stopper can be set not only The abutting portion 26 may be provided on the abutting portion 28. [0052] In the foregoing example, the elastic retaining portions 22, 24 and the abutting portions 26, 28 respectively provided thereon constitute the elastic portion. The holding portion 18, but the number of the elastic holding piece portions constituting the elastic holding portion is not limited to two, and may be set at intervals of three or more in the circumferential direction of the portion of 200934983. The more the number, the contact with the wire In addition, in any case, the elastic holding piece is suitable for the body [0053] (Modification 1) 5 6 Fig. 6 is a view showing a modification of the power supply terminal 2 of the first embodiment. In Fig. 6, the same components as those of the above-described power supply terminal 2 are denoted by the same reference numerals, and the description thereof will be omitted.

The shape is 15 shape. Thereby, the longitudinal or thinner wires (external wires) can also be ensured as the shape of the abutting portion. (Modification 2) Fig. 7 is a view showing a modification of the power supply terminal 2 of the first embodiment. Fig. 7(a) and Fig. 7(c) are views in the direction of the tube axis when the power supply terminal is mounted in the form of a cold cathode fluorescent lamp. Fig. 7(b) is a perspective view of the front end portion of the power supply terminal 2 shown in Fig. 7(a), and Fig. 7(d) is a perspective view showing the front end portion of the power supply terminal 2 shown in Fig. 7(c). In the seventh embodiment, the same components as those of the above-described power supply terminal 2 are denoted by the same reference numerals and the description thereof will be omitted. 17 200934983 [0057] The power supply terminal 2 shown in Fig. 7 is a structure for ensuring that the positive electrical connection is more reliably bonded to the wire. [0058] The abutting portions 4A and 42 shown in Fig. 7(a) and Fig. 7(b) are examples in which the cross-sectional shapes of the two abutting portions are different. Moreover, by crimping the portion of the contact portion 4 that is not in contact with the wire 5 10 of the abutting portion 4 to the direction of the arrow shown in FIG. 7(b), a more reliable electrical connection can be obtained, and the mechanical connection can also be obtained. The wire is prevented from falling off. [0059] The abutting portions 44 to 46 shown in Figs. 7(c) and 7(d) are examples of the cross-sectional shape of the left and right asymmetry. Further, by crimping the portion of the wire 1〇1〇 of the abutting portions 44 and 46 that is not in contact with the direction of the arrow shown in FIG. 7(d), a more reliable electrical connection can be obtained, and mechanically. It can also be used as a wire to prevent falling off. <Embodiment 2> The power supply terminals 48 and 53 of the second embodiment are shown in Fig. 8. In the second embodiment, the power supply terminals 48 and 53 of the second embodiment are the same as those of the above-described power supply terminal 2, and the same components as those of the power supply terminal 2 are denoted by the same reference numerals, and the description thereof will be omitted. [0060] The power supply terminal 48 shown in FIG. 8(a)® extends from the cylindrical wall of the main body portion 16 in parallel with the central axis 16A, and includes a rectangular connecting portion in which the intermediate portion 20 is bent at a right angle. 5〇 and an elastic gripping portion 52 provided at an extending end of the connecting portion 5〇. The elastic grip portion 52 includes a square plate portion orthogonal to the central axis, i.e., a base portion, and an elastic piece portion 52B, 52c extending from the base portion 52. Each of the elastic piece portions 52B and 52C has a rectangular shape extending toward the side of the main body portion 16 with respect to the side portion of the base portion 52 facing the 200934983. The elastic piece portion 52B52c is curved inwardly (to the central axis 16A) in a "&lt;" shape, and the wire 〇 (Fig. 1 and Fig. 2) is elastically held between the tops of the curved portions. Also in this example, the base portion 52A functions in the same manner as the above-described stopper 3 (Fig. 5). 5 [〇〇62] The power supply terminal 48 composed of the outer conductor 10B is in contact with each other by the outer lead wire 10B", so the vertical or main body portion 6 is opposed to the glass container 6 (Fig. 1). However, the slight inclination 'external wire 1() B can still effectively move between the top portions. Therefore, the excessive force is applied to the wire portion 10B. [0063] Further, the elastic holding portion 52 is excellent in the insertion and removal of the wire 1〇B. Therefore, the detachability of the power supply terminal 48 to the glass container 6 is improved. [〇〇64] The elastic holding portion 54 of the power supply terminal 53 shown in Fig. 8(b) is basically the same as the elastic holding portion 52 described above. That is, the elastic piece portions 54B, 54C are formed by one of the extension portions 54A. The feature is that the connection portion 56 is included, and a strip shape 15 ° is extended from the body portion 16 to be long. In the power supply terminal 53, the material constituting the main body of the elastic holding portion 54 can be made small in size, and the weight can be reduced as a whole. [0065] Further, the external wire i〇 The advantage of B for the insertion of the elastic grip portion 54 is the elastic 挟The portion 52 (Fig. 8(a)) is the same. On the other hand, the outer lead wire 10B is not easily pulled out by the elastic grip portion 54. When the elastic wire 54 is pulled out, the outer wire 1 〇 B 'connecting portion 56 is pulled out. As a result, the elastic piece portion 54C is also displaced inwardly and pressed against the external lead wire 10B, and the frictional force between the elastic piece portion 54C and the external lead wire 1 is increased. The power supply terminal 53 can be conveniently used in the case of the glass container 6, and can be conveniently used in the case of 19 200934983. [〇_ Again, in this example, the base 54A functions as the above-mentioned stopper 30 (Fig. 5) (Embodiment 3) The power supply terminal 58 of the third embodiment is shown in Fig. 9. The power supply terminal 58 of the third embodiment is different from the first embodiment in the configuration of the elastic holding portion.

[_7] The elastic gripping portions 6〇, 64 shown in Fig. 9(4) and Fig. 9(b) are There is an arc-shaped cross section. The elastic gripping portion _ is an example in which the shape of the circle (four) extends from the two ends to the terminal end, and the book holding portion 64 allows the two ends of the arc to be distant from each other. An example in which the direction is curved. [0068] The elastic gripping portions 6A, 64 are connected to the main body portion 16 by the connecting portion 62 66. [0069] Figures 9(c) and 9(d) The elastic gripping portions 68, 72 are formed such that the inter-stand portion of the cross section which is integrally formed in a "u" shape protrudes in an arc shape. The elastic grip portion 68 is an example in which the shape of the arc is extended from the two ends of the arc to the end, and the elastic grip portion _ is a shape that is bent in a direction away from each other from the both ends of the arc to the end. An example. [0070] The elastic grip portions 68, 72 are coupled to the main body portion 16 by the joint portion wind μ, respectively. [〇〇71]And 'in the state of inserting the wire 1G, the radius of the arc is equal to the radius of the guide wire 200934983 line 10 (external wire 10B)', and the elastic gripping portions 60, 64, 68, 72 are arc-shaped. The inner surface of the portion is in surface contact with the outer peripheral surface of the wire 10. Further, in a state where the wire 10 is not inserted, the arc-shaped portion is plastically deformed to be integrally reduced. Thus, when the wire 10 is inserted, the elastic retaining portions 60, 64, 68, 72 5 are elastically deformed and spread outward in the radial direction of the wire 10, and hold the wire 10 by its resilience. &lt;Embodiment 4&gt; The power supply terminal 8A of the fourth embodiment is shown in Fig. 10. Fig. 1(0) shows the positive side view of the power supply terminal 80 in the state of the end of the cold cathode fluorescent lamp 4, and the tenth (b) figure shows the same side view. The main body of the power supply terminal 80 is basically the same as the main body portion 16 of the power supply terminal 2 of the first embodiment. Therefore, the same component numbers are given and the description thereof is omitted. [0073] The elastic grip portion 2 is composed of a pair of elastic piece portions 840, and an abutting portions 88, 90 provided with extensions 15 provided on the respective elastic piece portions 84, 86. [0074] The pair of elastic piece portions 84, 86 constitute a cone portion 96 having two slits 92 94 which are extended by the body portion 16 and open in the tube axis direction of the glass container 6. Shape setter. [〇〇75] A push screw 98 is provided on the outer surface of the cone portion 96. 2〇, the power supply terminal 8〇 has a ring nut 100° that is screwed with the push-out screw 98. [0076] If the power supply terminal 80 composed of the above-mentioned configuration is inserted in the following state, the power supply terminal 80 is externally inserted into the cold (4) (10) The Bud Guide (4) B is inserted into the abutting portion 88, and the elastic piece portion is the entire body 21 200934983. The two abutting portions 88, 90 are in contact with the external lead wire 10B. Further, the abutting portions 88, 9A are pressed against the external lead wire 10B' by the locking ring head screw stomach coffee to hold the external wire _. [0077] Further, it is also possible to allow the elastic resilience of the elastic pieces 5, 86 to be held in the state before the first nut of the first ring nut is screwed to hold the outer wire 10B. The outer lead 10B is held in a state in which the first nut is tightened and tightened. Further, in the above-described example, the conical portion having two slits is provided, but the number of slits provided to be opened is not limited to two, and may be three or more. Further, a slit connected to the slit formed in the tapered portion may be formed on the main body portion side. For example, in the first frame (the phantom, a pair of slits 102 as shown by the broken lines may be openly disposed at positions opposite to each other in the wall of the body portion 16 (the slits on the other side are not shown) Thereby, the holding force of the main body portion 16 with respect to the glass container 6 can also be adjusted by adjusting the degree of fastening of the ring head nut 1 〇〇 15. In particular, the power supply terminal 80 is applied to the glass container 6 It is useful to use a cold cathode fluorescent lamp having a different diameter of a plurality of sizes. <Embodiment 5> The power supply terminal 11A of the fifth embodiment is shown in Fig. 11. In the fifth embodiment, 20 power supply terminals 11 and In the first embodiment, the same components as those of the above-described power supply terminal 2 are denoted by the same reference numerals, and the description thereof will be omitted. [0080] The body portion 112 of the power supply terminal 110 is the same. One of the plurality of cylindrical members (six in this example) is provided with a slit 114 at a predetermined interval from the center axis of the cylindrical body at a predetermined interval in the circumferential direction of the central axis. Most of the strips (six in this case) are rectangular The elastic piece 118 is formed by extending one end portion of the cylindrical body portion 116 in which the slit 114 (the slit 114 is not reached) is not opened. 5 Ο 10 15 e 20 [0081] Each elastic piece 118 is a system The whole body is bent inwardly from the vicinity of the base end portion on the side of the cylindrical portion 116 as a base point, and is bent locally in the vicinity of the end portion in the vicinity of the wrap end portion into a r shape. When the power supply terminal 110 is externally inserted into the cold cathode discharge lamp, the glass container 6 is not damaged by the corner of the tip end of the elastic piece 118, so that it is easy to insert. The diameter of the virtual cylinder that protrudes from the top of each of the "<"-shaped % curved portions (the surface side of the glass-filled container 6) in the elastic sheet n8 is set to be shorter than the outer diameter of the glass container 6. Fig. 12 is a view showing a state in which the power supply terminal 11 is mounted before and after the cold cathode discharge lamp 4. [0084] The power supply terminal 11A composed of the configuration just described is externally inserted at the end of the cold cathode fluorescent lamp 4. At the time of the portion, the top of the "<" of each elastic piece 118 is abutted outside the glass container 6. The elastic piece 118 is elastically elastically deformed (elastically deformed) toward the outer side in the radial direction of the glass container 6 with the base end portion as a base point, and is maintained by the resilience of the elastic sheet 118. Thereby, the glass container (9) is attached thereto. The shape of the elastic piece (10) slit 114), the number, the arrangement position, and the like are not limited to the above, and the cylindrical body portion 116 is positioned in the main body portion m in a state of a slight axis. The point is that the glass container 6 can be elastically supported in the main body portion 112. 23 200934983 <Embodiment 6> The power supply terminal 16A of the sixth embodiment is shown in Fig. 13. Fig. 13(a) is a front view of the power supply terminal 160, and Fig. 13(b) is the same as the right side view. The main body portion of the power supply terminal 160 is substantially the same as the main body portion 16 of the power supply terminal 25 of the embodiment, and the same reference numerals are given to the same components, and the description thereof will be omitted. [0086] The elastic holding portion 162 provided in the main body portion 16 is formed by punching a metal circular plate (for example, stainless steel) having elasticity and punching it, and the peripheral portion thereof is joined to the main body portion by laser welding or the like. 16. 10 [〇〇87] The elastic grip portion 162 having a disk shape, the central portion of which is punched into a shape as shown in Fig. 13(b), and has a plurality of (three in this example) Center protruding tongues 162A, 162B, 162C. The front end portion (the wandering portion) of the tongue pieces 162A, 162B, and 162C has a sharp cut section of punching and cutting. Further, the tongues 162A, 162B, and 162C are not required to be elastic sheets. 15 [0088] The diameter d2 of the imaginary circle at the front end of each of the tongue pieces 612A, 162B, 162C is set to be smaller than the diameter d1 of the outer wire 10B. [0089] Fig. 13(c) is a front elevational view showing a state in which the power supply terminal 160 is fitted into the cold cathode fluorescent lamp 2 from the side of the main body portion 160. Further, in Fig. 13(c), the elastic grip portion 162 is drawn in a cross-sectional view cut at a position corresponding to the b 2 〇 _ B line shown in Fig. 13(b).

External lead 10B. Further, the front end portions of the tongue pieces 162A, 162B, and 162C, that is, the portions abutting against the outer lead wire 10B are sharp edges, so that the front end portion bites into the outer periphery of the outer lead wire 1〇Β. [0091] By allowing the tabs 162A162B162C to bite into the outer peripheral surface of the outer lead 10B, the contact area of the abutting portion with the outer lead 1B can be increased by 5 Ο 10 15 20 and the contact portion is prevented from being oxidized. It can improve the reliability of electrical connectivity. Further, the number and shape of the tongue pieces (elastic pieces) are not limited to the above-mentioned ones. <Embodiment 7> The power supply terminal 18A of the seventh embodiment is shown in Fig. 14. The front view of the power supply terminal 180 is shown in Fig. M(a), and the right side view is shown in Fig. 14(b). The main body portion of the power supply terminal 180 is substantially the same as the main body portion 16 of the power supply terminal 2 of the embodiment, and the same reference numerals are given to the same components, and the description thereof will be omitted. The elastic holding portion 162 provided in the main body portion 16 is formed by pressing a metal circular plate (for example, a steel plate for a spring) into a shallow dish shape, and the bottom portion thereof is punched into a predetermined shape and is obtained. The bottom peripheral portion is joined to the end portion of the body portion 16 by laser welding or the like. The elastic grip portion 162 is a so-called tapping nut, and the pair of tooth portions 182A182B are configured such that the bottom portions face each other and protrude. The opposing distance d3 between the teeth i82A, 182B shown in Fig. 14(b) is set to be shorter than the outer diameter of the outer lead 1 〇B. [0095] As shown in FIG. 14(c), when the power supply terminal 180 having the above-described configuration is inserted into the cold cathode fluorescent lamp 2 while rotating from the main body portion 160 side in the direction of the arrow c, the tooth portion is replaced by the tooth portion. 182A, 182B and a bolt is formed on the outer circumference of the outer wire 25 200934983 1〇B. Further, the tooth portions 182A and 182B are slightly deflected with the base end portion as a base point, and the external wire 1 is held by the repulsive force thereof. Since the tip end portion of the tooth portions 182A, 182B is bitten into the bolt groove formed, the gums are formed. The contact area between the front end portion of the 182A, 182B and the external wire 1B is increased and the oxidation of the contact portion can be prevented, and the reliability of the electrical connection can be improved. Further, the power supply terminal 160 (Fig. 13) of the sixth embodiment is pulled out by the cold cathode fluorescent lamp 2, and the tongue pieces 162A, 162B, and 162C are bitten into the external lead 10B, so that it is difficult to take out. However, the power supply terminal of the seventh embodiment can be reused only when it is rotated in the direction opposite to the direction of the arrow C in the figure 14(c), so that it can be reused. &lt;Embodiment 8&gt; The figure is a perspective view showing a schematic configuration of the backlight unit 300 in which the light source has the cold cathode fluorescent lamp 4. Further, Fig. 15 is a view showing a diffusion plate 308, a diffusion sheet 310, and a lens sheet 312 which will be described later. [0096] The backlight unit 300 includes a peripheral device 3〇6 composed of a rectangular reflecting plate 302 and a side plate 3〇4 surrounding the reflecting plate 3〇2. The reflecting plate 302 and the side plates 3〇4 are each formed with a reflection. a film (not shown) which is attached to a main surface of one side of a sheet composed of PET (polyethylene terephthalate) resin (as an inner side when assembled as a peripheral 3〇6) The steamed ore 20 has aluminum, etc. [0097] In the above-mentioned peripheral device 3〇6, a plurality of (in this example, eight) cold cathode fluorescent lamps 4 are parallel to the long sides of the aforementioned reflecting plate 302. And being stored in the short side direction at equal intervals as a light source. [0098] Further, in the opening of the outer peripheral 306 A diffusion plate 26 200934983 308, a diffusion sheet 310, and a lens sheet 312 are provided. 5 Ο 10 15 20 [0099] A configuration in which the cold cathode fluorescent lamp 4 in the backlight unit 300 is mounted to the peripheral 306 will be described with reference to FIG. Further, in the illustrated example, the power supply terminal 2 of the first embodiment is used, but a power supply terminal including any of the second to fifth embodiments of the modification may be used. [0100] 'Upright setting on the reflection plate 302' For example, the connector 314 is formed by bending and forming a resilient metal plate. The cold cathode fluorescent lamp 4 is embedded in the body portion 16 of the power supply terminal 2 mounted at both ends thereof. The connector 314 is mounted on the peripheral 316 in one touch. Thereby, the power supply terminal 2 is electrically connected to the connector 314, and the power from the lighting circuit (not shown) is via the connector 314 and the power supply terminal 2. It is put into the cold cathode fluorescent lamp 4. <The problem of the cold cathode fluorescent lamp with the power supply terminal installed in the backlight unit and its solution> (1) The cold cathode fluorescent lamp 4 is only required by the connector The opening portion of 314 is embedded in the body portion 16 of the power supply terminal 2 Installed, there is a concern that the cold cathode glory 4 will deviate from its tube axis direction. Also, for example, a cold cathode fluorescent (four) sample containing a glass container with a rounded cross section, the installation direction of the tube is a problem. In the case of a profile, in order to effectively extract light from the backlight unit, the long or short diameter should be parallel to the reflector, but if it is offset from the circumference of the tube, the light extraction efficiency will be reduced. _1] Figure 17, The __ indicates the power supply terminal m and the connector 130. The electrical terminal 120 is configured to prevent displacement of the tube axis direction and the circumference of the sleeve when the cold cathode glory 4 connector is connected. Further, in the electric terminal 120 of the 2009, 2009, the same components as those of the power supply terminal 2 (the second and third figures) of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. [0102] The cylinder wall of the main body portion 122 of the power supply terminal 110 is opened and provided with five engagement holes 124. [0103] The connector 130 basically has the same configuration as the aforementioned connector 214. That is, the connector 130 is a press machine for slender sheets (phosphor bronze sheets) composed of phosphor bronze, and has a circular arc portion and a pair of opposite holding sheets 130A, 130B, and a joint portion connecting the two 10〇c is composed of 10%. Further, the arcuate portion of the one of the grip portions 130A is provided with an engaging projection 130D that protrudes inward. X, the width of the arcuate inner surface of the engaging projection 13〇D should preferably be equal to the thickness of the wall of the main body portion 122 of the power supply terminal 124. [0104] In the power supply terminal 12A and the connector 13A15 which are configured as described above, when the engagement hole 124 is engaged with the engagement projection 13G, the power supply terminal 120 is connected to the connector 13G. The cold cathode fluorescent lamp is offset from the tube axis direction and around the tube axis for the connector 130. (2) Since the outer peripheral portion of the main body portion of the power supply terminal described above is a cylindrical surface as a whole, the cold cathode fluorescent lamp 20 to which the power supply terminal is attached is mounted on the backlight unit and arranged in a flat operation. At the time of the stage, there is a problem that it is easy to make a rotation on the stage. [0106] Fig. 19 is a view showing a power supply terminal 140 which is placed on a flat surface and which is not easily rotated. Further, in the nineteenth, the same structure as the above-described power supply terminal 120 (Fig. 17 and Fig. 18) is given the reference numeral 200934983, and the description thereof is omitted. [0107] In the power supply terminal 140, a part of the outer peripheral surface of the main body portion 142 is defined as a flat surface 144. Thus, since the main body portion 142 is provided with the flat surface 144, the cold cathode fluorescent lamp provided with the power supply terminal is less likely to rotate in the flat surface. Moreover, at this time, it is preferable to match the mounting angles of the two power supply terminals 140 (the angle around the tube axis) so that the two flat faces 144 of the power supply terminals 140 provided in the both end portions of the cold cathode fluorescent lamp 4 are on the same plane. .

As shown in FIG. 20, when the power supply terminal 15 I40 is fitted into the connector 130 such that the flat surface 144 is engaged with the flat portion 152A, the cold cathode fluorescent lamp 4 can be prevented from deviating from the circumference of the tube axis with respect to the connector 130. . ❹ [〇11〇] (3) Power supply terminal 2 (Fig. 3) of the first embodiment, power supply terminal of the second embodiment (Fig. 8), power supply terminal of the third embodiment (Fig. 9), and fourth embodiment The grounding terminal 80 (the first) and the power supply terminal ιι (the 20th and 12th drawings) of the fifth embodiment are both elastic holding portions (such as the elastic holding portion 18 in the power supply terminal 2 of the embodiment). The main body portion 16 protrudes, so that when the processing is performed on the #光单源, the protruding portion touches the work table and other cold cathode fluorescent lamps, and the glass container that damages the wire 〇 6 parts. 29 200934983 [〇11] Fig. 21 shows a diagram of a power supply terminal 190 constructed to correspond to the aforementioned problem. In the power supply terminal 190, substantially the same components as those of the power supply terminal 2 (Fig. 2 and Fig. 3) of the first embodiment are denoted by the same reference numerals, and their description is omitted. [0112] The power supply terminal 190 is configured such that the protective portion 192 194 surrounding the outer lead 10B in a direction orthogonal to the tube axis extends from the elastic pieces 22, 24 at the end of the main body portion 16. Thus, the outer conductor 1B can be protected from the external force as much as possible by providing the protecting portions 192, 194' surrounding the outer conductor 1B. ❿ 10 [0114] In the foregoing example, the protective portions 192, 194 are extended from the main body portion 16 but may be separate from the main body portion 16 and joined as being integral with the main body portion 16. In the body portion 16. Fig. 22 shows the power supply terminal 196 thus constructed. Further, in the power supply terminal 196, the power supply terminal 15 2 (the second drawing and the third drawing) of the embodiment is substantially the same as the component number, and the description thereof is omitted. [0116] The power supply terminal 196 has a configuration of the power supply terminal 2 of the embodiment, and further includes a configuration of the protective member 198. The retaining member 198 has a cylindrical shape, and one end portion is externally inserted into the main body portion 16, and is joined to the main body portion 16 by laser welding or the like. Thus, by providing the protective member 198 surrounding the outer lead 10B, the outer lead 10B can be protected from the external force as much as possible. Further, according to the configuration described below, the cold cathode lamp 4 can be prevented from deviating from the tube axis direction with respect to the connector. 30 200934983 [0119] A cutout portion 198A, 198B as shown in the figure is provided at one end of the protective member 198. [0120] On the other hand, the connector 200 is provided with engagement projections 130E, 130F that engage with the cutout portions 198A, 198B when the power supply terminal 196 is inserted. Further, in the seat tube 200 shown in Fig. 22, substantially the same components as those of the seat tube 13 shown in Fig. 17 are denoted by the same reference numerals, and their description will be omitted.

Carbonated vinegar. The polycarbonate is easily deteriorated by ultraviolet rays having a wavelength of 313 [nm] generated by mercury. In this case, a phosphor which absorbs ultraviolet rays having a wavelength of 313 [nm] is preferably used. Further, as a fluorescent system that absorbs ultraviolet rays of 313 [nm], there are the following.

[0131] As such a phosphor, for example, a barium co-activated barium magnesium aluminate [BaMg2Al16〇27: Eu2+, Mn2+], [BaMgAli()〇i7: Eu2+ Mn2+] (abbreviation.

For example, blue only uses BAM-B (absorption 313 [nm]), green uses LAP (no absorption 313 [nm]), and BAM-G (absorption 313 [nm]), and red uses γ 〇χ (does not absorb 3l3 [nm]) and YVO (absorbing 313 [nm]) phosphor. At this time, as described above, the glare system of the absorption wavelength 313 [nm] is adjusted to be greater than 50% in the total weight composition ratio, whereby it is possible to prevent ultraviolet rays from leaking out of the glass tube. Therefore, when the phosphor layer 105 contains a phosphor that absorbs ultraviolet rays of 313 [nm], deterioration due to ultraviolet rays of the diffusion plate made of polycarbonate (PC) that closes the opening of the backlight unit can be suppressed. The characteristics as a backlight unit can be maintained for a long time. 5 [〇133] Here, the term "absorption of ultraviolet rays of 313 [nm]" is defined as an excitation wavelength spectrum near 254 [nm] (the excitation wavelength spectrum is excited by light when the wavelength of the glory is changed). When the intensity of the excitation wavelength and the luminescence intensity is 1 〇〇 [%], the intensity of the excitation wavelength spectrum of 313 [nm] is 80 [%] or more. Namely, the fluorescent system 10 which absorbs ultraviolet rays of 313 [nm] absorbs ultraviolet rays of 313 [nm] and can be converted into a visible light phosphor. (5-2) Color Reproducibility In a liquid crystal display device typified by a liquid crystal color TV, a high color reproduction is achieved with a ring of high image quality in recent years, and the backlight is used as the liquid crystal display device. In the cold cathode discharge 15 lamp and the external electrode discharge lamp used for the light source of the unit, the chromaticity range which is required to be reproduced is enlarged. [0134] Corresponding to such a requirement, for example, by using the following fluorescent system, the chromaticity range can be expanded more than that of the phosphor in the embodiment. Specifically, in the CIE 1931 chromaticity diagram, the chromaticity coordinate 20 value of the phosphor for high color reproduction includes a triangle which can be connected to the chromaticity coordinate value of the three phosphors used in the embodiment. And located at coordinates that extend the range of color reproduction.

[〇137](c)Red • · YOS, chromaticity coordinates: x=0.651, y=0.344 • YPN, chromaticity coordinates: x=〇.658, y=0.333 15 · MFG, chromaticity coordinates: x= 〇.711, y=0.287 Also, as mentioned above, it can also absorb ultraviolet light with a wavelength of 313 [nm], and YVO and YDS can also be used for high color, in addition to the three phosphor particles described here. Reproduction. Further, the chromaticity coordinate value described above is a representative value measured only by 20 powders of the respective phosphors, and the color of each phosphor is displayed by a measurement method (measurement principle) or the like. The degree coordinate value will have a number of different situations from the previous value. For reference, the chromaticity coordinate values of the phosphors of the respective phosphors of the first embodiment are Y〇X (x=0.644, y=0.353), LAP (x=0.351, y=0.585), BAM-B ( x=0.148, y=0.056) constitutes. 37 200934983 [0139] Further, the glory for illuminating each of red, green, and blue colors is not limited to one type, and may be used in combination with a plurality of types. Here, the case where the phosphor layer is formed by using the above-described high color reproduction phosphor particles will be described. The evaluation here is based on the area of the NTSC triangle of the chromaticity coordinate value of the three primary colors of the NTSC standard in the 5 CIE1931 chromaticity diagram, that is, when the phosphor for high color reproduction can be used. The area ratio of the triangles of the three chromaticity coordinates (hereinafter referred to as NTSC) is performed. For example, when BAM_B is used as the blue system, BAM-G is used as the green system, and γν〇 is used as the red system (example u, the NTSc ratio is 92 [%]', and SCA is used as the blue system. When BAm to G is used as the green system and yv〇 is used as the red system (Example 2), the NTSc ratio is ι〇〇[〇/0], and SCA is used as the blue system and BAM-G is used as the green system. When YOX is used as the red type (Example 3), the NTSC ratio is 95 [%], and the brightness can be increased by 10 [%] compared to Examples 1 and 15 Example 2. [0142] Also, for evaluation here Since the chromaticity coordinate value is measured in the state of a liquid crystal display device such as a lamp, the color reproduction range can be made before and after the color value is combined with the color filter. [0143] The power supply terminal of the present invention can be suitably used as a power supply terminal provided at an end portion of a cold cathode fluorescent lamp, such as a light source as a backlight unit constituting a liquid crystal display device.
