Can be prevented from colliding with the adapter 100.

  Hereinafter, an assembling procedure and a board mounting procedure of the connection device S having such a configuration will be described. First, the clamp part 320 and the holding part 330 of the contact 300 are inserted into the hole part 214b of the concave part 214 of the body 200 while being aligned. Then, both end portions of the base plate 310 of the contact 300 are press-fitted into the pair of slits 214 a of the concave portion 214 of the body 200. Then, the clamp part 320 and the holding part 330 are accommodated in the first area α1 of the accommodation space α, and the base plate 310 and the pair of contact parts 340 are accommodated in the recess 214.

  Thereafter, as shown in FIG. 10A, the pair of locking claws 230 of the body 200 are formed on the wide portions 21 a of the pair of locking holes 21 of the substrate 20, and the pair of locking projections 250 are formed on the pair of locking holes 22. Each is inserted into the heel area 22b while being aligned. At this time, the contact portion main body 342 of the pair of contact portions 340 of the contact 300 comes into elastic contact with the surface of the substrate 20.

  Thereafter, as shown in FIG. 10B, the pair of locking claws 230 are moved from the wide portion 21 a to the narrow portion 21 b of the pair of locking holes 21.

At the same time, the pair of locking projections 250 are moved from the collar area 22b of the pair of lock holes 22 toward the mountain portion 22a. Then, the pair of locking projections 250 are guided while being pressed by the crests 22 a of the pair of lock holes 22. As a result, the tip ends of the pair of arm portions 240 are transferred to the substrate 20.
Swing along the surface of

  Thereafter, as shown in FIG. 10C, when the pair of locking claws 230 reach the narrow portion 21b of the pair of locking holes 21, they are locked to the outer edge of the narrow portion 21b.

  At the same time, the pair of locking projections 250 passes over the peak area 22 d beyond the peak portions 22 a of the pair of lock holes 22. Then, the pressing of the peak portions 22a against the pair of locking projections 250 is released, and the pair of arm portions 240 return from the swinging state by their own elastic force. Thereby, a pair of latching convex part 250 falls to the valley area 22c, and is latched by the peak part 22a.

  At this time, the contact portion 340 of the contact 300 slides on the substrate 20 and elastically contacts the contact pattern 23.

  Thus, by a pair of latching convex parts 250 being latched by peak part 22a, a pair of latching claw 230 is prevented from moving from narrow part 21b to wide part 21a of a pair of latching holes 21. The Thereby, the state where the body 200 is attached to the substrate 20 is maintained.

  When removing the body 200 from the substrate 20, the pair of locking projections 250 protruding from the pair of locking holes 21 toward the bottom surface of the substrate 20 are gripped with a finger and pressed inward. Then, the engagement between the pair of locking projections 250 and the pair of mountain portions 22a is released. In this state, the pair of locking projections 250 is moved to the pair of heel areas 22b beyond the pair of mountain portions 22a. At the same time, the pair of locking claws 230 are moved from the narrow portion 21b of the pair of locking holes 21 to the wide portion 21a. Thereafter, the pair of locking projections 250 are pulled upward from the flange area 22b of the pair of locking holes 22, and the pair of locking claws 230 are pulled upward from the wide portions 21a of the pair of locking holes 21, thereby 200 can be easily removed from the substrate 20.

  Hereinafter, a procedure for connecting and removing the adapter 100 connected to the cold cathode fluorescent lamp 10 as described above to the connection device S mounted on the substrate 20 as described above will be described. First, the second connecting portion 120 of the adapter 100 is installed while being aligned on the tip of the clamp portion 320 of the contact 300 in the housing space α of the body 200. Then, the end of the lamp body 11 of the cold cathode fluorescent lamp 10 is installed on the tip of the holding part 330 of the contact 300.

  Thereafter, the end of the lamp main body 11 of the cold cathode fluorescent lamp 10 and the adapter 100 are pushed into the housing space α of the body 200. Then, the tip of the clamp part 320 of the contact 300 is pressed by the second connection part 120 of the adapter 100 and elastically deforms in a direction away from the holding wall part 213 in the accommodation space α.

  At the same time, the distal end portion of the holding portion 330 of the contact 300 is pressed against the end portion of the lamp main body portion 11 of the cold cathode fluorescent lamp 10 and is elastically deformed in a direction away from the holding wall portion 213 in the accommodation space α.

  After that, when the second connecting portion 120 of the adapter 100 is fitted into the intermediate portion of the clamp portion 320, the clamp portion 320 moves back in a direction approaching the holding wall portion 213 in the accommodation space α by its own elastic force. As a result, the second connecting portion 120 is clamped between the intermediate portion of the clamp portion 320 and the uneven surface 213a of the clamping wall portion 213. As described above, the second connecting portion 120 is sandwiched between the clamp portion 320 and the uneven surface 213a of the sandwiching wall portion 213, whereby the adapter 100 and the contact 300 are electrically and mechanically connected.

  At the same time, when the end of the lamp main body 11 of the cold cathode fluorescent lamp 10 is fitted into the intermediate part of the holding part 330, the holding part 330 approaches the sandwiching wall part 213 in the accommodation space α by its own elastic force. Move back to. As a result, the end of the lamp main body 11 is sandwiched between the intermediate part of the holding part 330 and the edge part of the opening 211 of the body 200.

  With the adapter 100 and the cold cathode fluorescent lamp 10 thus electrically and mechanically connected to the connection device S, the cold cathode fluorescent lamp 10 is heated in the length direction as shown in FIG. 9B. When it expands and deforms, the elastic deformation portion 130 of the adapter 100 extends, and the first connection portion 110 of the adapter 100 moves to the right side of the drawing in the length direction together with the lead terminal 12 of the cold cathode fluorescent lamp 10.

  On the other hand, as shown in FIG. 9C, when the cold cathode fluorescent lamp 10 is subjected to thermal contraction deformation in the length direction, the elastic deformation portion 130 of the adapter 100 contracts, and the first connection portion 110 of the adapter 100 becomes the cold cathode. It moves together with the lead terminal 12 of the fluorescent lamp 10 to the left side in the figure in the length direction.

  At this time, the uneven surface 213a of the sandwiching wall portion 213 locks the second connecting portion 120 of the adapter 100, and the second connecting portion 120 is thermally expanded or deformed or heated by the lamp main body portion 11 of the cold cathode fluorescent lamp 10. The movement in the length direction along with the contraction deformation is suppressed.

  When removing the adapter 100 and the cold cathode fluorescent lamp 10 from the connection device S, the adapter 100 and the cold cathode fluorescent lamp 10 are lifted upward. Then, the upper end portion of the intermediate portion of the clamp portion 320 of the contact 300 is pressed by the second connection portion 120 of the adapter 100 and elastically deforms in a direction away from the holding wall portion 213 in the accommodation space α. At the same time, the upper end portion of the intermediate portion of the holding portion 330 of the contact 300 is pressed against the end portion of the lamp main body portion 11 of the cold cathode fluorescent lamp 10 and elastically deforms in a direction away from the holding wall portion 213 in the accommodation space α.

  Thereafter, when the second connection portion 120 of the adapter 100 exceeds the upper end portion of the intermediate portion of the clamp portion 320 and the end portion of the lamp main body portion 11 of the cold cathode fluorescent lamp 10 exceeds the upper end portion of the intermediate portion of the holding portion 330. The adapter 100 and the cold cathode fluorescent lamp 10 are taken out from the connection device S upward.

  When the cold cathode fluorescent lamp 10 and the connection device S are electrically and mechanically connected using the adapter 100 as described above, the first connection portion 110 is mechanically connected to the lead terminal 12 of the cold cathode fluorescent lamp 10. The cold cathode fluorescent lamp 10 is thermally expanded or deformed in a state where the second connecting portion 120 is connected and clamped between the clamp portion 320 of the contact 300 of the connecting device S and the holding wall portion 213 of the body 200. Even if it contracts and deforms, the elastic deformation part 130 of the adapter 100 expands and contracts with the thermal expansion deformation or thermal contraction deformation, and absorbs the thermal expansion deformation or thermal contraction deformation. For this reason, as in the conventional example, the end of the lamp main body 11 of the cold cathode fluorescent lamp 10 and the lead terminal 12 are pressed against or pulled by the adapter 100 attached to the connection device S by thermal expansion deformation or thermal contraction deformation. Since peeling can be prevented, the load applied to the cold cathode fluorescent lamp 10 during thermal expansion deformation or thermal contraction deformation can be reduced.

Hereinafter, an adapter (buffer) according to a second embodiment of the present invention will be described with reference to the drawings.

The curved portion 434a has both end portions continuous to both ends of the front end portion of the base plate 431 and both ends of the rear end portion of the first connecting plate 432, and an arcuate top portion connecting the both end portions. The curved portion 434a is curved in a substantially semicircular arc shape so that the top portions are opposed to each other, and can be elastically deformed in a direction in which the both end portions are separated from or approach each other (that is, can be expanded and contracted). Yes.)

  In the other two deformable portions 434, the curved portion 434a is between the both ends of the front end portion of the first connecting plate 432 and both ends of the rear end portion of the second connecting plate 433 or the front end portion of the second connecting plate 433. This is the same as the one deformed portion 434 described above except that it is provided between both ends of the first plate portion and both ends of the upper end portion of the third plate portion 413. The spring force of the three deformable portions 434 is set to such a force that no load is applied to the sealed portions of the lead terminal 12 of the cold cathode fluorescent lamp 10 and the lead terminal 12 of the lamp body 11 when expanding and contracting. ing.

  The adapter 400 to which the cold cathode fluorescent lamp 10 is thus connected is inserted into the accommodation space α of the connection device S of the first embodiment, and the second connection portion 420 is intermediate between the contact 300 clamp portion 320 of the connection device S. And the sandwiching wall portion 213 of the body 200. In this state, as shown in FIG. 13B, when the cold cathode fluorescent lamp 10 is thermally expanded and deformed in the length direction, both end portions of the curved portions 424a of the elastic deformation portion 430 of the adapter 400 are separated from each other. It is elastically deformed (that is, the elastically deforming portion 430 is extended), and the first connecting portion 410 of the adapter 400 is moved to the right side of the drawing in the length direction together with the lead terminal 12 of the cold cathode fluorescent lamp 10.

That is, the deformable portion main body 531 can be expanded and contracted. The spring force of the deformable portion main body 531 is set to a force that does not apply a load to the lead terminal 32 of the hot cathode fluorescent lamp 30 and the sealing portion of the lead terminal 32 of the lamp main body portion 31 when expanding and contracting. .

At the same time, the connecting portion 730 of the two contacts 700 is inserted into the locking hole 41 of the substrate 40. Then, the claw portions of the pair of locking arms 731 of the connection portion 730 are respectively locked to both edge portions of the lower surface of the locking hole 41 of the substrate 40. Thereafter, the locking arm 731 is connected to the electrode pattern of the substrate 40 by soldering or the like. In this way, the connection device S ′ is mounted on the substrate 40.

  Hereinafter, a procedure for connecting the two adapters 500 connected to the hot cathode fluorescent lamp 30 as described above to the connection device S ′ mounted on the substrate 40 in this way will be described. First, the end of the hot cathode fluorescent lamp 30 and the two adapters 500 are accommodated in the accommodating space α of the connection device S ′. At the same time, the lamp body 31 of the hot cathode fluorescent lamp 30 is housed in the lamp housing recess 631.

  At this time, the second connection part 520 and the lamp body part 31 of the two adapters 500 are inserted between the two contacts 700. Then, the bent part 721 of the clamp part 720 of the contact 700 is pressed outwardly by the second connection part 520. Thereby, the clamp part 720 elastically deforms in the direction away from each other.

When the second connecting portions 520 get over the bent portions 721, the clamp portions 720 are elastically deformed in a direction approaching each other by their own spring force. Thereby, the bent part 721 elastically contacts the second connection part 520, and the adapter 500 and the hot cathode fluorescent lamp 30 are sandwiched between the support part 650 . In this way, the second connection portions 520 of the two adapters 500 are electrically and mechanically connected to the clamp portions 720 of the two contacts 700, respectively.

  In this state, as shown in FIG. 19B, when the hot cathode fluorescent lamp 30 is thermally expanded and deformed in its length direction, the two lead terminals 32 of the hot cathode fluorescent lamp 30 and the second adapter 500 1 connecting portion 510 moves to the right side of the figure. At this time, the deformable portion main body 531 of the elastic deformable portion 530 of the adapter 500 is elastically deformed (i.e., extended) in the direction in which the first connecting portion 532 and the second connecting portion 533 are separated from each other. The thermal deformation of the hot cathode fluorescent lamp 30 is absorbed by the elastic deformation of the elastic deformation portion 530.

  On the other hand, as shown in FIG. 19C, when the hot cathode fluorescent lamp 30 is subjected to heat shrinkage deformation in the length direction, the two lead terminals 32 of the hot cathode fluorescent lamp 30 and the first of the two adapters 500 are used. The connecting portion 510 moves to the left side in the figure. At this time, the deformable portion main bodies 531 of the elastically deformable portions 530 of the two adapters 500 are elastically deformed (ie, contracted) in the direction in which the first connecting portion 532 and the second connecting portion 533 approach each other. The thermal deformation of the hot cathode fluorescent lamp 30 is absorbed by the elastic deformation of the elastic deformation portion 530.

  When removing the two adapters 500 and the hot cathode fluorescent lamp 30 from the connecting device S ', the adapter 500 and the hot cathode fluorescent lamp 30 are lifted upward. Then, the bent portions 721 of the two contacts 700 are pressed by the second connection portions 520 of the two adapters 500, respectively. Thereby, the clamp part 720 of the contact 700 is elastically deformed in a direction away from each other. Then, when the second connecting portion 520 gets over each of the bent portions 721, the adapter 500 is detached from the connecting device S '.

  In this way, when the hot cathode fluorescent lamp 30 and the connection device S ′ are electrically and mechanically connected using the adapter 500, the first connection portions 510 of the two adapters 500 are connected to the two of the hot cathode fluorescent lamps 30. The hot cathode fluorescent lamp 30 is electrically and mechanically connected to each lead terminal 32 and the second connection portion 520 of the adapter 500 is sandwiched between the two contacts 700 of the connection device S ′. Even if the thermal expansion deformation or thermal contraction deformation occurs, the elastic deformation portion 530 of the adapter 500 expands or contracts with the thermal expansion deformation or thermal contraction deformation, and absorbs the thermal expansion deformation or thermal contraction deformation. Yes. Therefore, as in the conventional example, the end portion of the lamp body 31 of the hot cathode fluorescent lamp 30 and the lead terminal 32 are connected to the adapter 500 connected to the connection device S ′ by the thermal expansion deformation or thermal contraction deformation. Since it can be prevented from being pressed or peeled off, the load applied to the hot cathode fluorescent lamp 30 during the thermal expansion deformation or thermal contraction deformation can be reduced.

  Note that the adapters 100, 400, and 500 are adapters that connect the lead terminals of the electronic component and the contacts of the connection device of the same component, and the first connection portion that is electrically and mechanically connected to the lead terminal. A second connection portion that is spaced apart from the first connection portion in the length direction of the electronic component and can be electrically and mechanically connected to the contact; and first and second connection portions As long as it is provided with an elastically deformable portion that is elastically deformable in accordance with thermal expansion deformation or thermal contraction deformation in the length direction of the electronic component, the design can be arbitrarily changed. FIG. 20 is a schematic perspective view showing a design change example of the adapter of the first embodiment. FIG. 21A is a schematic perspective view showing a design change example of the adapter of the second embodiment. ) Is a schematic perspective view showing another design change example of the adapter of the second embodiment, FIG. 22 is a schematic view showing a design change example of the adapter of the third embodiment, and (a) is a side view. (B) is a plan view.

  Further, the design of the first connecting portions 110, 410, and 510 can be arbitrarily changed as long as it is a portion that can be electrically and mechanically connected to the lead terminal by soldering or welding. For example, the first connection portion may be a coil body (see FIG. 11) or a circular arc body into which the lead terminal can be inserted. The connection between the first connection portion and the lead terminal is exemplified by soldering or welding, but any connection method may be used as long as it can be electrically and mechanically connected. .

  About the 1st connection parts 410 and 510, the insertion hole in which a lead terminal is inserted should just be provided. Whether or not to provide the depression 411b is arbitrary. The depression 411b can also be provided in the first connection portion having another shape such as the first connection portion 510.

  The second connection portions 120, 420, and 520 can be arbitrarily changed in design as long as they are portions that can be electrically and mechanically connected to the contacts. For example, other cylindrical bodies such as a circle, a triangle, a polygon such as a pentagon other than the end turn part into which the end of the main part of the electronic component can be inserted, or the main part of the electronic component is opposed. It can be set as a plate-like body or a rod-like body. In the latter case, the second connection portion may be sandwiched between the contact and the body together with the lamp body portion, or may be sandwiched between the contact and the lamp body portion. Further, the second connecting portion does not need to face the lamp main body portion 11 and may be positioned on the opposite side of the lamp main body portion 11 with a gap from the first connecting portion.

  In addition, other members such as a skirt portion 440 and a flange portion 450 can be further provided at the rear end of the second connection portion 420 as shown in FIG. Similarly, the second connecting portions 120 and 520 can be provided with the other members.

  The elastic deformation portions 130, 430, and 530 are arbitrary as long as the elastic deformation portions 130, 430, and 530 are interposed between the first and second connection portions and can be elastically deformed according to thermal expansion deformation or thermal contraction deformation in the length direction of the electronic component. It is possible to change the design. For example, it can be a rubber body, a plate-like body having a substantially S-shape, O-shape, U-shape, V-shape, meandering curve shape (see FIG. 22), etc. In addition, when the second connection portion is located on the opposite side of the lamp main body portion and spaced from the first connection portion, the elastic deformation portion can be a solid rubber body.

  In the above embodiment, the adapter is a coil spring or a press-molded product, but is not limited to this. It is also possible to combine the first and second connection portions and the elastic deformation portions of the first to third embodiments. For example, the first connection part 400 or 500 can be used as the first connection part of the adapter 100. Further, as shown in FIG. 22, as the adapter 500 ′ for the hot cathode fluorescent lamp 30, a first connection portion 510 ′ that is a rod-like body, a second connection portion 520 ′ that is an end winding portion, and a meandering curve A configuration including an elastically deforming portion 530 ′ having a shape is also possible. In this case, the lengths of one elastically deforming portion 530 'and the other elastically deforming portion 530' are different.

  In addition, although the said adapter shall electrically and mechanically connect the lead terminal of an electronic component, and the contact of a connection apparatus, it replaces with this and is interposed between the lead terminal of an electronic component, and a connection apparatus. And it can be set as the shock absorber which connects both only mechanically. In this case, the shock absorber is a first attachment portion that is attached to the lead terminal instead of the first connection portion, and a second attachment portion that can be attached to the connection device instead of the second connection portion; Just do it.

  For the connection devices S and S ′, the end of the main part of the electronic component, the lead terminal and the body that can accommodate the adapter connected thereto, and the connection that is accommodated in the body and can be electrically connected to the adapter It is possible to arbitrarily change the design as long as it has means.

  When the buffer is used instead of the adapter, the connection device needs to further include holding means for mechanically holding the buffer. In this case, the connecting device may be directly electrically connected to the lead terminal of the electronic component.

  The design of the clamping wall portion 213 can be arbitrarily changed as long as the second connecting portion of the adapter can be clamped with the clamp portion of the contact. Therefore, it is arbitrary whether or not the uneven surface 213a is provided on the holding wall portion 213.

  The clamping wall portion 213 is provided with an uneven surface 213a as a stopper, but the second connecting portion moves in the length direction of the electronic component in accordance with thermal expansion deformation or thermal contraction deformation of the electronic component. Any stopper may be provided as long as it is a stopper that suppresses this. For example, it can be a pair of convex portions that can come into contact with both end portions of the second connection portion, a concave portion in which the second connection portion is fitted, or the like.

  With respect to the locking claw 230, the thickness of the locking portion 21 is slightly smaller than the width of the wide portion 21 a of the locking hole 21 of the substrate 20 and the width of the narrow portion 21 b of the locking hole 21. As long as it is a substantially L-shaped member having a base end portion slightly smaller than the width dimension, the design can be arbitrarily changed. There may be at least one locking claw.

  The design of the arm portion 240 can be arbitrarily changed as long as it is a long member facing the width direction of the locking claw 230 and the tip end portion thereof can swing along the surface of the substrate. In addition, the arm portion 240 can be disposed so as to be displaced in the width direction of the locking claw 230 and the body 200. For example, the arm 240 can be provided at one end of the second box 220. In this case, the lock hole 22 of the substrate 20 may be provided according to the position of the arm portion. Therefore, the locking hole 21 and the lock hole 22 do not need to communicate with each other. There may be at least one arm part.

  The locking protrusion 250 is a cylindrical body, but can be arbitrarily changed in design as long as it is a protrusion that can be inserted into the lock hole 22. The body 600 can also be provided with the arm portion 240 and the locking convex portion 250 and mounted on the substrate 20.

  The contacts 300 and 700 can be arbitrarily changed in design as long as they can be electrically and mechanically connected to the second connection portion of the adapter and can contact the contact pattern of the substrate.

  The shape of the clamp portion 320 can be arbitrarily changed as long as the second connection portion can be sandwiched. Moreover, although the clamp part 320 clamped the 2nd connection part 120 between the clamping wall parts 213, it is not limited to this. For example, the second connection portion may be sandwiched between a pair of clamp portions.

  In addition, the stopper can be provided on the inner surface of the clamp portion. Even if the stopper is provided in the clamp portion in this manner, the same effect as that of the uneven surface 213a can be obtained by contacting the second connection portion of the adapter. The stopper may be provided on the outer surface of the second connection portion of the adapter. A similar stopper can be provided on the clamp portion 720 of the contact 700.

  The shape of the holding portion 330 can be arbitrarily changed as long as the main body portion of the electronic component can be held. In addition, the holding portion 330 is sandwiched between the edges of the opening portion 211 of the body 200, but is not limited thereto. For example, the main body part may be sandwiched between a pair of holding parts. The contact 700 can also be provided with the holding portion.

  The contact portion 340 only needs to be electrically connected to the substrate 20. For example, the contact portion 340 can be a plate-like body that can be inserted into the through-hole of the substrate 20, or can be a bowl-shaped body that can contact the contact pattern of the substrate and be surface-mounted, or a circuit of the substrate A lead wire for connecting to a pattern or other electronic component or the like can be formed into a shape capable of being crimped. It is also possible to change the design so that the contact portion 340 is a separate body and brought into contact with the base plate 310.

  In the above embodiment, the present invention has been described as being connected to the cold cathode fluorescent lamp 10 or the hot cathode fluorescent lamp 30. However, the present invention is not limited to this.
