Is the greater than or equal to 100 11 ❹ ❹ 200929746 N tensile strength. The above connection seam 3d or welding means that the mechanical connection is made while the electrical connection of the wire can is made. The element 1 and the discharge lamp body 10 10 are formed. In the insertion of the power supply member i: the main body portion 2 in which the glass bulb electrical member 1 is inserted in the work of the connection means is used in the glass bulb 11 : the front end portion of the blade electrode 14 is further electrically connected to the terminal "the glass bulb 11 is guided" The end portion and the power supply terminal 3 are two == the specified size (7), and further, the gap G2, the wire 12 is formed with a predetermined size and then: = a gap is formed between the sub-3 and the electrode lead 12. 3: £;=== In the state in which the three-foot portion 3b is close to each other, the package is frosted. According to the present embodiment, (1) (4) the power supply terminal 3 is electrically connected to the electric wire 12, so that the conduction of the wire 12 can be substantially increased by the power supply terminal 3. The area is such that the power can be stably supplied. The main body 2 and the power supply terminal 3 are integrated by the electric and electrical component 1, so that the parts can be processed as soon as possible, thereby facilitating the management of the money parts. When the discharge lamp 2 is assembled or the discharge lamp 2 is transported, and even if stress is applied to the power supply terminal 3, since the main body portion 2 is formed of wood and an elastic body having a predetermined hardness, the action on the electric jade wire 12 can be alleviated. Mechanical load. Also, the end of the glass bulb 11 The predetermined size G1 is separated from the power supply terminal 3, so that the stress 12 200929746 applied to the power supply terminal 3 serves as the end of the glass bulb 11. Further, since a gap is formed between the power supply terminal/the electrode lead 12, Therefore, the direct load of the direct current pole 12 is further relieved. Therefore, the glass bulb can be prevented from being damaged. (4) When the power supply terminal is formed in the main body portion 2, the body portion 2 and the power supply terminal 3 are The combination becomes strong. Since a plurality of protrusions are formed inside the insertion opening 2c of the main body portion 2, the glass bulb 11 can be inserted into the inner diameter portion of the main body portion 2, and thus (6) is made of a tree oak The portion 2 has thermal conductivity and dissipates heat in the vicinity of the electrode 14, thereby suppressing the effect of the seal portion eclipsing (7) because the guide portion 3b is formed in the power supply terminal 3, and the three wires 12 are easily inserted. The position of the power supply end larger than the quilting portion 3d ensures that the end portion of the glass bulb 11 is folded, and the length dimension L2 of the surface of the four sides is double. Therefore, the electrode lead 12 is easy to bend the stress of the sealing portion of the tube 1, thereby preventing the glass from being blocked.

The socket box 31 has a socket box main body 13200929746 and an electrical connection terminal 34 disposed in the socket box main body 33. The socket case main body 33 is formed of a polybutylene terephthalate (PBT) resin or an Acrylonitrile Butadiene Styrene (ABS) resin, and has a substantially rectangular parallelepiped shape. A semi-cylindrical receiving recess 33a for mounting the main body portion 2 of the power feeding member 1 and a rectangular parallelepiped electrical connecting terminal providing recess 33b connected to the receiving recess 33a are formed on the upper surface of the socket case main body 33. . Further, in the front end opening portion of the receiving recess portion 33a, a rib 33c that is inwardly tapered in a semi-cylindrical shape is formed. Insertion holes 33d for mounting the electrical connection terminals 34 are formed on both sides of the electrical connection terminal providing recess 33b. Further, at the four corners of the cartridge main body 33, a fastening hole 33e into which the engaging claw of the socket cover 32 described later is inserted is formed. Further, fastening claws 33f are formed downward from both side walls of the socket case main body 33. ❹ 1: The conductive material such as the transfer terminal ^Kutian Gonggong copper is formed in a substantially 17-shape, and the base 34a and the pedestal leg whose front end extends from the both sides of the base 34a toward the lower side 34b constitutes. The semi-cylindrical connection recess A for mounting the power supply terminal 3 is formed on the susceptor 34a. Therefore, the electric connection terminal 34 is bent in an L shape from the connection recess 34e. A cut-and-raised piece 34d cut toward the outside is formed on the 34b. The cut and raised piece 34d functions to prevent detachment when the pedestal leg 3 is inserted into the insertion hole 33d. Similarly to the socket case main body 33, the ml seat 32 is formed of PBT resin, ABS resin, or the like, and has a substantially rectangular parallelepiped shape, and the lower protruding shape is shown in Fig. 6, and the socket cover is turned upward toward 200929746. A semi-cylindrical fixing recess 32a is formed as a fixing portion at a position facing the receiving recess of the socket main body 33. Further, a pressing concave portion 32b having a cylindrical shape smaller than the fixing concave portion is formed as a pressing portion at a position where the fixing concave portion 32a of the disk is connected and faces the connecting concave portion 34c of the electrical connection terminal %. . Further, a rib 3 2 c having a semi-cylindrical diameter reduction is formed in the front end opening portion of the pressing recess portion 3 2 b. In the assembly of the lamp socket 30 as described above, first, the electrical connection terminal 34 is mounted on the socket case main body 33. Specifically, the pedestal leg 34b of the electrical connection terminal 34 is inserted into the insertion hole 33d of the socket case main body 33 to be mounted. Next, the engaging claws 32f of the socket cover 32 are inserted into the engaging holes 33e formed at the four corners of the socket case main body 33. The lamp socket 30 is assembled by the above steps (refer to Fig. 8). Next, the assembly and mounting steps of the discharge lamp unit 4A will be described with reference to Figs. 9 to 11 . The discharge lamp unit 40 is composed of a discharge lamp 20 and a lamp socket 3, for example, mounted on a substrate or a casing 5 of a backlight of a liquid crystal panel. Mounting holes 51 corresponding to the number of mountings of the discharge lamp unit 40 are formed on the substrate or the casing 50. However, for convenience of explanation, it is shown that three mounting holes 51 are formed in the casing 50. The unit 4A is mounted in the mounting hole 51. In FIG. 9, the case 50 and the socket case 31, the discharge lamp 20, and the socket cover 32 are sequentially shown. First, when the socket case 31 is attached to the casing 5, the engaging claws 33f of the socket case 31 are inserted into the mounting holes 51. Then, the engaging claws 33f are elastically engaged to the edge of the hole of the mounting hole 51 on the back surface of the casing 50 via the mounting hole 51 (see Figs. 10 and 12). 15 200929746 ^ times, as shown in Fig. 1, the discharge lamp 2 is placed in the socket box 3l ί L, the main body 2 of the power supply member 1 is fitted into the recess of the socket box The power supply terminal 3 is placed in the connection recess 34 of the terminal 34. Then, as shown in Fig. 11, the socket cover 32 is sequentially engaged on the socket case 31. This engagement is performed by inserting the engaging claws 32 of the socket cover 32 into the engaging holes 33e formed at the four corners of the socket case main body 33, and pushing the insertion until the mounting hole of the basket body 50 is pushed. . Therefore, similarly to the engaging claws 33f of the socket case 31, the engaging claws 32f are elastically engaged to the edge of the hole of the mounting hole 51 on the back surface of the casing 50 via the mounting hole 51 (see Fig. 12). Therefore, the series of assembly and mounting steps can be performed so as to be stacked from the upper side in the vertical direction with respect to the casing 5, so that the mechanical load on the discharge lamp 20 can be reduced and the mechanical load can be reduced. Simplification of the work is achieved, thereby facilitating the automation of the assembly and installation steps. In the state described above, the engaging claws 32f of the socket cover 32 are engaged with the engaging holes 33e of the socket case main body 33 and the mounting holes 51 of the casing 50, so that not only the socket cover 32 is fastened to the socket box. 31, and the socket cover 32 itself is also snapped to the casing 50. In other words, the socket cover 32 includes the socket box 31 and the discharge lamp 20, and is fastened to the casing 50. At this time, since the socket box 31 itself is also fastened to the casing 50', it is double-knitted to the value body. 5〇. Referring to Fig. 12, reference will be made to the description. At the time of the engagement, the main body portion 2 of the power feeding member 1 is pressed into the fixing recess 32a of the socket cover 32, and is sandwiched between the socket case 31 and the socket cover 32 with a slight elastic deformation. At this time, since a gap is formed between the main body portion 2 and the glass bulb n 16 200929746, the gap can be uniformly reduced by the pressing of the fixing recess 32a, and the center shaft can be clamped without causing a shift in the center axis. On the other hand, the power supply terminal 3 of the power supply member 1 is pressed into the pressing recess 32b of the socket cover 32, and is elastically energized while being connected to the connection recess 3 of the electrical connection terminal 34. At this time, the power supply terminal 3 can be bent so as to be offset with respect to the central axis of the glass bulb 11, and between the connection concave portion 34c and the pressing concave portion 32b, the elastic recovery stress and the pressing force are used to ensure proper contact. The pressure is thus configured in a state in which the reliability of the electrical connection is high. In addition to this, even if there is a dimensional error in the power supply member, etc., the error can be absorbed by the bending. Further, when the socket cover 32 is fastened, the dimensional relationship is as follows: initially, the pressing recess 3 of the socket cover 32 is in contact with the power supply terminal 3, and second, the fixing recess 32& of the socket cover 32 and the elastic member of the power supply member 1 are formed. The body portion 2 is in contact. Therefore, in the fastening process of the socket cover 32, first, the power supply end is slightly bent in the direction of the connection recess 34c of the electrical connection terminal 34 to increase the contact pressure with the connection recess 34c. Then, the main body portion 2 is elastically deformed by being pressed to the fixing recess 32a of the socket cover 32, and the power supply terminal is further pressed to the pressing recess portion 32b, thereby increasing the contact pressure with the connecting recess portion 34c. Here, the power supply terminal 3 is reliably connected to the electric terminal 34 with an appropriate contact pressure, and the discharge lamp 2 is reliably secured to the socket 30. • Next, as shown in Fig. 12, the power supply member 1 of the discharge lamp 20 is clamped to the socket 3G. The main body portion 2 of the power supply member 保持 is held between the receiving recess portion 33a of the socket case main body and the fixing recess portion 32a of the socket cover 32. At 17 200929746, the main body portion 2 is restricted from moving in the axial direction by the rib 32C and the rib 33c. Further, the power supply terminal 3 of the power supply member 1 is held between the connection recess portion 34c of the sub-34 and the pressing recess portion 32b of the socket cover 32. At this time, as shown in FIG. 13, the base 34a of the electrical connection terminal 34 is provided to be elastically deformable in the vertical direction, and is provided apart from the electrical connection terminal installation recessed portion 33b of the socket case main body 33. Therefore, it is possible to appropriately secure the power supply terminal. 3 contact pressure.

(3) When the discharge lamp 20 is mounted in the lamp socket 30, the end=sub3 can be bent with respect to the glass bulb 11, thereby ensuring power supply reliability and the connection terminal 34. The appropriate contact pressure can be configured in a state in which the glass bulb is electrically connected. Further, since the space is formed between the main body portion 2 and the glass bulb, the gap is reduced by the pressing center axis of the fixing recess 32a, so that the mounting with high positional accuracy can be performed, and the 箅2 is biased at 4 〇. shift. (4) A shock or vibration that is relieved by the transportation or use of the discharge lamp unit is absorbed by the main body portion 2 of the power feeding member 1, so that it is possible to prevent the glass bulb 11 from being damaged or not, and the malfunction of the glass tube 11 is not caused, and It can alleviate the influence of shock and vibration on the power supply component, so that it can be stably supplied. 5) The glass bulb 11 is thermally expanded in the radial direction and the axial direction by the lighting of the discharge lamp 20. However, the main body portion 2 of the elastic body can be swollen and deformed. (6) Since the glass tube U and the power supply terminal 3 are closed by the predetermined size G1 ', the vibration or thermal expansion of the glass ball f 11 affects the power supply terminal 3

Moreover, it absorbs the ribs with the absorption of the main body portion 2, thereby supplying power more stably. (7) Since the rib 32c and the rib 33c of the power supply member "leather socket 3' are restricted from moving in the axial direction, the discharge lamp 20 can be disposed at a predetermined position. (8) Since the electrical connection terminal 34 is elastically deformable in the up and down direction and is separated from the socket case main body 33, the connection force of the power supply terminal 3 can be appropriately corrected. (9) Since the electrical connection terminal 34 is formed by simply bending into a single shape from both sides of the connection concave portion 34e, the structure can be simplified. (1〇) When the socket cover 32 is fastened, the dimensional relationship is as follows. First, the pressing recess of the socket cover 32 is in contact with the power supply terminal 3, and then the fixing recess 仏 of the socket cover 32 and the elastic member 1 of the power supply member i are formed. The main body portion 2 is in contact, so that the power supply terminal 3 is reliably connected to the electric connection terminal 34 with an appropriate contact pressure, and the discharge lamp 2 is reliably held on the lamp socket 3''. The electric lamp (11) is formed by the insertion port 2c of the main body portion 2 and the glass bulb 11 . Therefore, the main body portion 2 of the power supply member 被 is pressed into the socket with a slight elastic deformation, and is clamped to the socket case 31 and the socket cover 32 in the body portion 2 itself. 19 200929746 曰, ίΓ2 reliably holds the discharge lamp 20 through the lamp socket 3°. (12) By the fastening structure of the lamp socket %, the fastening becomes = ' ^ Only the socket cover 32' is detached in a state in which the wire 32 is mounted, thereby facilitating the replacement of the discharge lamp 2, etc. effect.

❹ Since the main body portion 2 of the power supply member 1 is made of cut rubber and has conductivity, the heat in the vicinity of the electrode 14 can be efficiently radiated to the vicinity of the heat of the light through the glass tube η and the main body portion 2 to a lamp having a large surface area. The socket 30 is distributed. In addition to this, heat in the vicinity of the electrode 14 is conducted from the electrode lead 12 and the power supply terminal 3 to the electrical connection terminal 34 and the lamp socket 30', whereby heat is also dissipated. Next, a first embodiment of a lamp power feeding member and a discharge lamp according to the present invention will be described with reference to Figs. 14 to 19 . Fig. 14 is a perspective view showing a power supply terminal, and Figs. 15(a) and 15(b) are a front view and a cross-sectional view of the power supply terminal, and Figs. 16(a) and 16(b) are the same as Fig. 15 ( a), FIG. 15(b) is a front view and a cross-sectional view showing an angle of 90 degrees, FIG. 15 is a right side view of the FIGS. 15(a) and 15(b), and FIG. 18 is a power supply member. FIG. 19 is a cross-sectional view showing a discharge lamp. The same or equivalent portions as those of the first embodiment are denoted by the same reference numerals and the description thereof will not be repeated. In the present embodiment, as shown in FIG. 19, after the power feeding member 1 is inserted into the end portion of the glass bulb 11 of the discharge lamp main body 10, a plurality of portions of the power supply terminal 3 are caulked by a press machine to form a joint. The caulking portions 3dl and 3d2 are crimped to electrically and mechanically connect the power supply terminal 3 and the electrode lead 12. Of course, the stamping step of forming the caulking portions 3d1, 3d2 by the punching machine is to omit the electrode wires in the 20 200929746 bulb 11 and to feed the electrode wires out to the communication portion 3a of the power supply terminal 3,000. ^ For the convenience of explanation, and there are 3 shapes 17, the power supply terminal 3 is cylindrical and the end... For example, the end portion is used for:

=: Cheng = the foreign side uses the call to the second power == the convex portion protruding toward the inner side of the communication portion 3 & the %, so that the inner wall of the opposite direction of the ϋ ϋ convex portion 362, 362 is displayed to the electrode lead 12, thus = The electrical terminal 3 is electrically and mechanically connected to the electrode lead 12. Here, the caulking portion 3d1 and the caulking portion 3d2 are formed at positions shifted from each other in the axial direction and the circumferential direction of the power supply terminal 3, and the sewn portion and the caulked portion 3d2 are formed in the axial direction and the circumferential direction. Moved to the location. 12. Specifically, it is offset in the axial direction! The size of the caulked portion is formed by shifting approximately 90 degrees in the circumferential direction. Therefore, each of the convex portions knows that the 3e2 is also displaced from each other and protrudes toward the inner side of the communicating portion 3a, and the crimping electrode lead is made of ruthenium rubber by insert molding in the power supply terminal 3 as shown in Fig. 18 . The main body portion 2' constitutes a power supply member 丨. Then, as shown in FIG. 19, the power supply member 1 is inserted into the end portion ' of the glass bulb 11 of the discharge lamp main body 1', and the two portions of the front end portion of the power supply terminal 3 are caulked by a press machine, thereby The crimping portions 3dl and 3d2 are formed. Further, at this time, the position of the caulking portion 3d2 is secured to the end portion of the glass bulb η, that is, the sealing portion from the electrode lead 12 is a length dimension of 4 mrn or more 200929746 L2 Row punching of the slit portions 3di, 3d2 The outline of the steps is inserted into the sewing machine, and the equipment is prepared with an angle of approximately _% of the angle and = two heads with the rush.

Further, since the caulking portions 3d1, 3d2 are formed at positions shifted in the power supply terminal 3, in the axial direction and the circumferential direction, and are formed at positions offset from each other, the electrode wires are reduced due to the pressing force caused by the caulking. 12 is broken, or the peripheral wall of the power supply terminal 3 is cut. Further, since the caulking portions 3cU and 3d2 form the convex portion 3 core 3e2 from different directions, the direction in which the pressing force is applied to the electrode lead T2 by the k-bend 3el 3e2 is different, and as a result, the bending direction of the electrode lead 12 is different, and Reliably ensuring the contact of the bump 22 200929746 L 'is thus able to supply power stably. Further, the device as the caulking device can be disposed at an angle of substantially 90 degrees, so that the arrangement can be adjusted to 0. In the above-described embodiment, the axis of the power supply terminal 3 is cut off. The case where the size of the caulking 4 is shifted by approximately 9 degrees in the circumferential direction to form the caulking portion 3 (Π, 3d2) has been described.

The front end opening portion of the receiving recess 33a is formed with an inwardly facing rib 33c. . Further, on both side walls of the socket case main body 33 connected to the receiving recess portion 33a, an electrical connection terminal 配 is provided by insert molding 23 200929746. Therefore, the electrical connection terminal % is disposed so as to straddle between the side walls of the socket main body 33. Further, at the four corners of the socket case main body, 'there are five large 33e for the following socket cover 32# fastening claws to be fastened, and on the outer side of both side walls of the socket case main body, = for mounting to the 憧The slider member of the body or the like has a broadcast (talking (4) and a snap-in month 33i in the vertical direction before and after the == member 33g. In addition, the electrical connection terminal 34 is disposed in the socket case main body. It is also possible to install it in the form of inlay molding, or it can be mounted by assembly in the same manner as in the first embodiment. u. As shown in Fig. 21 (4) and Fig. 21 (f), the electrical connection terminal 3 - 4 is composed of a read or a scale. The conductive material is formed in a substantially mouth shape and is constituted by the base 34a and the front end extending from the both sides of the base toward the lower side by the base leg 34b. The base is formed with a ground for mounting the electric Since the semi-cylindrical connection recessed portion 34c of the terminal 3 is formed in a shape of an eleven shape from the both sides of the connection recessed portion 34c #, the connection recess portion 34c is formed in a slit (sHt) shape. The cut inlet 34e_ having a substantially square shape is formed with a contact piece 34f. The pedestal 34a is connected, and the other side is separated from the pedestal 34a by the cut-in entrance to be a free end. The contact piece is always elastically energized toward the upper side rotation direction with the connection portion with the base's seat as a fulcrum. In other words, it is elastically deformable in a state in which it protrudes slightly upward from the surface of the susceptor 34a (see FIG. 21(b)).

Therefore, after the socket case 31 is mounted, the discharge lamp 20 is placed, and the socket cover 32 is fastened from above the socket case 31. Therefore, the mechanical load applied to the discharge lamp 20 can be reduced, and the glass bulb 11 can be prevented from being damaged or the like. As described above, according to the present embodiment, in addition to the same effects as those of the above-described respective embodiments, since the contact piece 34f is formed on the electrical connection terminal 34, the contact pressure with the power supply terminal 3 can be sufficiently ensured even in the discharge lamp. When the unit 40 is subjected to impact or vibration during transportation or use, it is also possible to prevent failure such as contact failure, and reliability can be improved. Further, the glass bulb n is thermally expanded in the radial direction and the axial direction by the lighting of the discharge lamp 20, but the contact piece 34f can be elastically deformed, so that the thermal expansion can be absorbed via the power supply terminal 3, and the glass ball can be alleviated. The stress of the tube u on the sealing portion is concentrated. Further, since the socket case 31 of the lamp socket 30 is attached to the substrate or the casing 5 by the sliding operation, the button socket 30 for attaching the lamp socket 30 to the back side of the substrate or the casing 5 can be made. Will not stand out. Therefore, for example, it is effective when it is applied to a configuration in which a plurality of substrates are stacked and the interval between the substrates is narrow. Next, an embodiment of the light-emitting device of the present invention will be described.

Here, 26 200929746 of the illuminating device includes a display device or a so-called lighting device that illuminates the space. For example, it can be applied to various display devices such as a backlight of a liquid crystal panel, and is applicable to lighting fixtures used indoors or outdoors. Further, in the case of the backlight device, a direct mode, a sidelight method, or the like can be applied. According to the light-emitting device, a light-emitting device which functions as the discharge lamp unit 40 of the embodiment can be provided. Next, another embodiment of the discharge lamp unit will be described with reference to Figs. 2A to 28 . Fig. 26 is an exploded perspective view of the discharge lamp unit, Fig. 27 is a perspective view of the discharge lamp unit, and Fig. 28 is a plan view of the discharge lamp unit. It is to be noted that the same or equivalent parts as those of the second embodiment of the lamp socket and the discharge lamp unit are denoted by the same reference numerals and the description thereof will not be repeated. In Fig. 26, the lamp socket 30 is constituted by a socket case 31 and a socket cover 32 that is fastened to the socket | 31. The socket case 31 has a box shape having a substantially rectangular parallelepiped shape, and a guide groove 61 bent from the opening side side = L sub-shape is formed on the inner side wall thereof. Further, the configuration of the electrical connection terminal or the like is the same as that of the second embodiment. The m-socket cover 32 has a substantially rectangular parallelepiped shape, and the extending portions of the both side walls are configured as elastically deformable elastic arms 62. Further, on the outer surfaces of the both side walls, the engaging projections 63 facing the guiding grooves 61 are formed at four locations, and the stopper projections 64 are formed on the distal end side of the elastic arms. In the configuration of the lamp socket 30 as described above, the socket case 31 is slidably attached to the substrate or the casing in the same manner as in the second embodiment, and then the discharge lamp 20 is placed and the socket cover 32 is fastened. At the time of the engagement, first, the latching projection 63 of the socket cover % is slidably moved in the vertical direction from the opening side along the guide groove 61, that is, below 27 200929746. Next, the engaging projection 63 is slidably moved in the horizontal direction along the guide groove 61, that is, to the left in the drawing. At this time, the stopper projection 64 may collide with the front end wall 65 of the socket case 31, but if the movement is further advanced, since the elastic arms 62 are elastically deformable, the elastic arms 62 of both sides are elastically deformed toward the inner side, thereby blocking The stopper projection 64 passes over the front end wall 65 of the socket case 31, and then, the elastic arm 62 returns to elasticity, and the stopper projection 64 is fitted into the guide groove 61 on the front side. Ο Ο By the above steps, as shown in FIGS. 27 and 28, the assembly of the discharge lamp unit 40 is completed. However, for example, when the discharge lamp 2 is replaced, the elastic arm 62 is elastically deformed inward, and the The opposite operation during assembly releases the snap fit of the socket cover 32. Therefore, according to the present embodiment, the socket cover 32 is slid in the vertical and horizontal directions and fastened to the socket case 31, so that the discharge lamp 2G can be reliably and stably held in the engaged state. Further, it is possible to provide a discharge lamp unit 4 that is easy to replace and replace the discharge lamp.
