Description

  The present invention relates to an adapter device for connecting a lead terminal of an electronic component such as a hot cathode fluorescent lamp and a connection device, and a connection device to which the adapter device is connected.

  Conventionally, to protect the lead terminals of lamp components such as a hot cathode fluorescent lamp and a cold cathode fluorescent lamp, there is a conductive cap that covers the end of the lamp body of the lamp and the lead terminal protruding from the end. is there.

  The cap has a cylindrical body that covers the end of the lamp body, and a connection portion that is electrically and mechanically connected to the lead terminal by a conductive adhesive or solder, and the cylindrical body is a connection device. As a result, the lead terminal and the contact of the connecting device are electrically connected to each other (see Patent Documents 1 and 2).

  That is, instead of directly holding the lead terminal in the contact, the cap cylinder is clamped so that the load due to the clamping is not applied to the lead terminal of the lamp component and its root portion.

Japanese Utility Model Publication No. 64-488514 JP 2006-351529 A

  By the way, the lamp component is used as a backlight of a display such as a car navigation system. That is, the lamp component may be used in a high-temperature environment such as a summer sun. When a lamp component is placed in such a high temperature environment, the lamp component may thermally expand.

  When the end of the lamp body is covered with a cap, and the lamp part is thermally expanded in a state where the cap body is sandwiched between the contacts of the connecting device, the end of the lamp body and the lead terminal of the lamp part are capped. It is pressed inside, thereby applying a load to the end of the lamp body and the lead terminal. For this reason, a malfunction may occur in the lamp component.

  Moreover, when the lamp component is pressed against the cap by thermal expansion, the cap moves in the length direction of the lamp component. Then, the cylinder of the cap slides between the contacts, and the cylinder is worn. For this reason, the contact between the cap and the contact may become unstable.

  The present invention was devised in view of the above circumstances, and an object thereof is an adapter device capable of absorbing thermal expansion or thermal contraction of an electronic component such as a lamp component and a connection to which the adapter device is connected. To provide an apparatus.

  In order to solve the above-described problems, an adapter device according to the present invention includes at least two connection members that respectively connect an electronic component having at least two lead terminals and a connection device of the same component having at least two contacts. And an insulating means for insulating between the connecting members. The connecting member includes a first connecting portion electrically and mechanically connected to the lead terminal, and a first connecting portion in the length direction of the electronic component. A second connection portion that is spaced apart from the first connection portion and that can be electrically and mechanically connected to the contact; and an electronic device provided between the first and second connection portions Elastic deformation portions that are elastically deformable in response to thermal expansion or contraction in the length direction of the component, and the insulating means is disposed between at least the first connection portions of the connection members. 1 insulating portion.

  In the case of the adapter device, the electronic component is thermally expanded or contracted in a state where the first connecting portion of the connecting member is electrically connected to the lead terminal and the second connecting portion is electrically and mechanically connected to the contact. Even if it does, when the elastic deformation part elastically deforms, the said thermal expansion or thermal contraction can be absorbed. For this reason, it is possible to prevent the electronic component from being pressed against or peeled off from the connection member by the thermal expansion or contraction of the electronic component. When contracting, the load applied to the main body of the electronic component and its lead terminal can be reduced. Moreover, when the elastically deforming portion is elastically deformed, the first insulating portions of the insulating means can prevent the first connecting portions from being displaced and contacting each other.

  Preferably, the insulating means further includes a second insulating part disposed between the elastically deforming parts. In this case, when the elastically deforming portion is elastically deformed, the second insulating portion can prevent the elastically deforming portions from being displaced and contacting each other.

  It is preferable that the second connection portion can be disposed along the main body portion of the electronic component. In this case, since the main body portion is interposed between the second connection portions, when the elastic deformation portion is elastically deformed, the second connection portions are displaced and come into contact with each other. Can be deterred.

  Preferably, the insulating means further includes a third insulating portion disposed between the second connection portion and the main body portion. In this case, when the elastically deforming portion is elastically deformed, the third insulating portion can prevent the second connecting portions from being displaced and contacting each other.

  The third insulating portion may be a cylinder that covers the main body portion. In this case, the second insulating portion is a portion continuous with an end portion of the third insulating portion, and is provided with at least two through holes through which lead terminals of electronic components are respectively passed. Preferably, the first insulating portion is a plate-like body that is continuous with the end portion of the second insulating portion, and is interposed between the first connecting portion and the lead terminal.

  In this case, the insulating means can be easily attached to the electronic component simply by inserting the lead terminals of the electronic component into the through holes and inserting the main body portion into the third insulating portion. In addition, the first insulating portion functions as a work table when the first connecting portion of the connecting member is connected to the lead terminal in a state where the insulating means is attached to the electronic component. Therefore, the connection of the first connection portion to the lead terminal is simplified. Further, the through hole functions as a guide means for guiding the lead terminal during the thermal expansion or thermal contraction. For this reason, it is possible to prevent the lead terminal and the first connecting portion from moving in a direction outside a predetermined direction.

  It is preferable that the second connection portion is fixed to the third insulating portion. In this case, the first connection is made on the first insulating portion by fixing the second connecting portion to the third insulating portion with the insulating means attached to the electronic component as described above. The portions can be connected to lead terminals, respectively. Therefore, the connection of the first connection portion to the lead terminal is further simplified. Moreover, since the second connecting portion is fixed to the third insulating portion, the third insulating portion moves along the main body portion during the thermal expansion or contraction, and The through holes of the second insulating part are moved along the lead terminals. That is, since the second and third insulating portions function as guides, it is possible to prevent elastic deformation in a direction different from the length direction of the electronic component of the elastic deformation portion.

  It is preferable that the first insulating portion is provided with at least two guide portions that guide the first connection portion along the length direction of the electronic component. In this case, during the thermal expansion or contraction, the first connecting portion moves along the length direction while being guided by the guide portion, so the elastic deformation portion is in a direction different from the length direction. It is possible to prevent elastic deformation.

  It is preferable that the first connection portion is a substantially L-shaped plate body and is provided with a connection hole into which a lead terminal is inserted. In this case, the lead terminals of the electronic components are respectively inserted into the through holes of the second insulating portion and inserted into the connection holes, and the lead terminals are respectively connected to the first connection portions by soldering or welding. Therefore, the connection of the first connecting portion to the lead terminal is further simplified.

  When the third insulating portion is a substantially cylindrical body, the second connecting portions are arcuate bodies that are respectively fixed to the outer peripheral surface of the third insulating portion, and together with the third insulating portion, It is preferable that the contact is rotatably held. In this case, since the third insulating portion of the adapter device has a substantially cylindrical shape and the second connecting portion has an arc shape that is fixed to the outer peripheral surface of the third insulating portion, the adapter device is in a rotated state. The third insulating portion and the second connecting portion are held between the contacts, and the second connecting portion and the contacts can be brought into contact with each other. For this reason, even in the above-described rotation state, it is possible to ensure electrical connection between the second connection portion and the contact. Moreover, since the lead terminal and the contact are respectively connected through the adapter device in the rotating state, the lead terminal and the main body thereof are connected as in the case where the lead terminal and the contact are directly connected in the rotating state. It is possible to prevent a load from being applied to the joint portion. Therefore, even if the lead terminal on one side of the electronic component is not substantially parallel to the lead terminal on the other side, the adapter device connected to the lead terminal on the one side is rotated and the second lead terminal of the adapter device is rotated. By interposing the third insulating portion and the second connecting portion between the contacts, the electrical connection can be achieved without applying a load to the lead terminal or the like.

  Preferably, the insulating means further includes a rotation restricting means for restricting the rotation of a predetermined amount or more. In this case, since the rotation of the adapter device is restricted by a predetermined amount or more by the rotation restricting means, the electrical connection between the second connecting portion and the contact is prevented from being disconnected by rotating the adapter device by a predetermined amount or more. can do.

  The 1st connection apparatus of this invention is equipped with the at least 2 contact respectively connected to the 2nd connection part of the connection member of the said adapter apparatus electrically and mechanically.

  Alternatively, the second connecting device of the present invention includes at least two contacts that sandwich the second connecting portion of the connecting member of the adapter device and the third insulating portion of the insulating means.

  In the case where the second connection device is of a board mounting type, it is preferable that the contact has a locking portion that is locked to the board. In this case, the contact can be easily attached to the substrate simply by locking the contact locking portion to the substrate.

  The adapter device A shown in FIGS. 1 to 3 includes an insulating cap 100 (that is, insulating means) that covers an end portion of the hot cathode fluorescent lamp 10 (that is, an electronic component), and is attached to the insulating cap 100 and is heated. Two connection terminals 200 (that is, connection members) connected to the two lead terminals 12 of the cathode fluorescent lamp 10 are provided. This will be described in detail below.

  As shown in FIG. 4, the hot cathode fluorescent lamp 10 is a well-known one having a lamp main body 11 and two lead terminals 12 protruding from both end faces in the length direction of the lamp main body 11. .

  As shown in FIGS. 1 and 2, the insulating cap 100 is formed by injection molding a resin having insulating properties, and has a cylindrical shape having a bottom portion into which an end portion of the lamp main body portion 11 can be inserted. The cap portion 110, the flat plate portion 120 integrally provided substantially at the center of the bottom portion of the cap portion 110, and the bottom portion and the flat plate portion 120 on both sides of the flat plate portion 120 at the bottom of the cap portion 110. And a pair of projections 130 having a substantially prismatic shape.

  A pair of flat bulges 111 that are respectively continuous with the upper end and the lower end of the flat plate 120 are provided at the upper end and the lower end of the cap 110 over the entire length of the cap. Rectangular protrusions 111a (that is, rotation restricting means) are provided in the middle portion of the ridge 111, respectively.

  The cap part 110 is divided into two regions by a pair of ridges 111. A substantially semicircular arc-shaped first flange portion 112 is provided on the outer peripheral edge of the open end of each region. In addition, two quarter-arc-shaped second flange portions 113 are arranged vertically on the outer peripheral edge portion of the end portion on the closing side of each region. A substantially semicircular arc-shaped recess between the first and second flange portions 112 and 113 in each region is a fitting portion into which the second connection portion 220 of the connection terminal 200 is fitted. When the cap part 110 is placed on the end of the lamp main body 11 of the hot cathode fluorescent lamp 10 with the second connecting part 220 fitted in the fitting part in this way, the cap part 110 is second. Between the connecting portion 220 and the lamp main body 11. That is, the cap part 110 corresponds to a third insulating part in the claims.

  Between the two second flange portions 113, a concave lead-out portion 114 for leading the elastic deformation portion 230 of the connection terminal 200 from the fitting portion is provided. In addition, a pair of first locking recesses 115 are provided between both ends of the first flange portion 112 and the pair of ridges 111, respectively. A pair of second locking recesses 116 are respectively provided between the ends of the two second flange portions 113 and the pair of ridges 111. Each of the first and second locking recesses 115 and 116 locks the first and second locking protrusions 221 and 222 of the second connection portion 220 of the connection terminal 200.

  A pair of guide grooves 121 (that is, guide portions) are provided on both side surfaces in the thickness direction of the tip portion of the flat plate portion 120. The guide groove 121 faces the length direction of the hot cathode fluorescent lamp 10 and its tip is opened. The first connection portion 210 of the connection terminal 200 is inserted into the guide groove 121 so as to be movable in the length direction. When the hot cathode fluorescent lamp 10 is thermally expanded or contracted, the first connection portion 210 of the connection terminal 200 moves along the guide groove 121. For this reason, it is suppressed that the 1st connection part 210 moves to directions other than the length direction of the hot cathode fluorescent lamp 10. FIG.

  As described above, the first connection portions 210 of the two connection terminals 200 are arranged on both side surfaces of the tip portion of the flat plate portion 120. That is, the front end portion of the flat plate portion 120 corresponds to the first insulating portion in the claims.

  Each protrusion 130 is a substantially prismatic protrusion. The protruding portion 130 is provided with a through hole 131 that penetrates the protruding portion 130 and the bottom of the cap portion 110 in the length direction of the insulating cap 100.

  The through hole 131 is a hole into which the lead terminal 12 of the hot cathode fluorescent lamp 10 can be inserted. The inner surface of the through hole 131 has a tapered shape that gradually decreases toward the tip end side of the flat plate portion 120. For this reason, even when the tips of the lead terminals 12 are not oriented in the same direction (that is, when the lead terminals 12 are not substantially parallel), the lead terminals 12 can be easily inserted into the through holes 131. The through-hole 131 functions as a guide means for guiding the lead terminal 12 along the length direction of the hot cathode fluorescent lamp 10 when the hot cathode fluorescent lamp 10 is thermally expanded or contracted. This prevents the lead terminal 12 from moving in a direction other than the length direction of the hot cathode fluorescent lamp 10.

  The first plate portion is movably inserted into the guide groove 121 of the insulating cap 100. The connection hole 211 is arranged substantially in a straight line with the through hole 131 in the length direction of the hot cathode fluorescent lamp 10 in a state where the first plate portion is inserted into the guide groove 121. That is, the lead terminal 12 of the hot cathode fluorescent lamp 10 can be inserted into the through hole 131 and the connection hole 211 in a state where the first plate portion is inserted into the guide groove 121.

  The elastic deformation portion 230 is a first connecting the deformation portion main body, which is a substantially S-shaped plate body in a side view, and one end portion of the deformation portion main body and the second plate portion of the first connection portion 210. And a second connecting portion that connects the other end of the deformable portion main body and the center of the tip of the second connecting portion 220 and fits into the lead-out portion 114 of the insulating cap 100.

  The deformable portion main body is elastically deformed in a direction in which the first connecting portion and the second connecting portion are separated from each other or in the approaching direction (that is, the length direction of the hot cathode fluorescent lamp 10). Specifically, the lead terminal 12 moves along the through hole 131 of the insulating cap 100, and the first connecting portion 210 moves along the guide groove 121 of the insulating cap 100, thereby causing the elastic deformation portion 230 to move. The deformable portion main body is elastically deformed in the length direction of the hot cathode fluorescent lamp 10 so as to expand and contract.

  The second connection part 220 is a substantially semicircular arc plate, and is provided at a pair of first locking projections 221 provided at both ends of the rear end part and at both ends of the tip part, respectively. And a pair of second locking projections 222. The second connection part 220 is fitted into the fitting part of the cap part 110. The first locking projection 221 is locked to the first locking recess 115 of the cap portion 110. The second locking projection 221 is locked to the second locking recess 116 of the cap portion 110.

First, the pair of first locking projections 221 of one connection terminal 200 is paired with the pair of first locking projections 115 in the region of the cap portion 110, and the pair of second locking projections of the connection terminal 200. The portions 221 are respectively locked to the second locking recesses 116 in the same region. Then, the second connection part 220 of the connection terminal 200 is fitted into the fitting part in the region. Accordingly, the second connection portion 220 of the connection terminal 200 is attached to the region. At the same time, the second connecting portion of the elastic deformation portion 230 of the connection terminal 200 is fitted into the lead-out portion 114 of the region.

Then, the elastic deformation portion 230 of the connection terminal 200 is disposed so as to face the one protrusion 130 of the insulating cap 100. In this way, the connection terminal 200 is attached to the insulating cap 100. The other connection terminal 200 is similarly attached.

  The adapter device A thus assembled is connected to the hot cathode fluorescent lamp 10 as follows. First, the two lead terminals 12 of the hot cathode fluorescent lamp 10 are respectively inserted into the two through holes 131 through the cap portion 110 of the insulating cap 100. Then, the lead terminals 12 are inserted into the connection holes 211 of the two connection terminals 200, respectively. At the same time, the end of the lamp body 11 of the hot cathode fluorescent lamp 10 is inserted into the cap 110. In this way, the cap portion 110 of the insulating cap 100 is put on the end portion of the lamp main body portion 11.

  Thereafter, the two lead terminals 12 are electrically and mechanically connected to the first connection portions 210 of the two connection terminals 200 by soldering or welding. In this way, the adapter device A is connected to the hot cathode fluorescent lamp 10.

  The rear plate portion 330 is provided with a lamp housing recess 331 for housing the lamp main body portion 11 of the hot cathode fluorescent lamp 10. The width dimension of the lamp accommodating recess 331 is slightly larger than the diameter of the lamp body 11 and smaller than the width dimension of the accommodating recesses 321, 351, 361, 371. Further, the depth dimension of the lamp accommodating recess 331 is smaller than the depth dimension of the accommodating recesses 321, 351, 361, 371.

  As shown in FIGS. 6E and 8, the support portion 380 is a substantially prismatic pedestal, and has a rectangular hole 381 that passes through the support portion 380 and the bottom plate portion 310. The width of the hole 381 is larger than the width of the protrusion 111a of the insulating cap 100, and the protrusion 111a can be inserted with play. Thereby, the rotation of the connection device S and the hot cathode fluorescent lamp 30 in the circumferential direction is restricted, and the electrical connection between the bent portions 421 of the two contacts 400 and the second connection portions 220 of the two connection terminals 200 is achieved.

At the same time, the connection portion 430 of the two contacts 400 is inserted into the locking hole 21 of the substrate 20. Then, the claw portions of the pair of locking arms 431 of the connection portion 430 are respectively locked to both edge portions on the lower surface of the locking hole 21 of the substrate 20. Thereafter, the locking arm 431 is connected to the electrode pattern of the substrate 20 by soldering or the like. In this way, the connection device S is mounted on the substrate 20.

  Hereinafter, a procedure for connecting the adapter device A connected to the hot 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 two fitting portions of the insulating cap 100 of the adapter device A and the second connection portions 220 of the two connection terminals 200 are inserted between the bent portions 421 of the two contacts 400. Then, the bent part 421 of the contact 400 is pressed against the fitting part and the second connection part 220, respectively, and the contact part 420 of the contact 400 is elastically deformed outward.

  When the fitting part and the second connection part 220 get over the bent part 421, the flat plate part 120 of the insulating cap 100 is placed on the accommodation recesses 321, 351, 361, and the ridge 111 is placed on the accommodation recess 371. Is done. At this time, the protrusion 111 a of the ridge 111 is inserted into the hole 381 of the support 380. At the same time, the contact part 420 is restored by its own spring force, and the bent part 421 is displaced in a direction approaching each other. Accordingly, the two bent portions 421 sandwich the fitting portion and the second connection portion 220 between the housing recesses 321, 351, 361, and 371 of the body 300. At this time, the bent portions 421 come into contact with the second connecting portions 220, respectively. In this way, the second connection portions 220 of the two connection terminals 200 are mechanically and electrically connected to the two contacts 400, respectively.

  In this state, as shown in FIG. 9B, when the hot cathode fluorescent lamp 10 is thermally expanded in the length direction, the two lead terminals 12 of the hot cathode fluorescent lamp 10 are in the through hole 131 of the insulating cap 100. Is moved to the left side in the drawing, and accordingly, the first connection portions 210 of the two connection terminals 200 are moved to the left side in the drawing along the two guide grooves 121 of the insulating cap 100. At this time, the deformable portion main bodies of the elastically deformable portions 230 of the two connection terminals 200 are elastically deformed (i.e., extended) in directions in which the first connecting portion and the second connecting portion are separated from each other. The elastic deformation of the elastic deformation portion 230 absorbs the thermal expansion of the hot cathode fluorescent lamp 10.

  On the other hand, as shown in FIG. 9C, when the hot cathode fluorescent lamp 10 is thermally contracted in the length direction, the two lead terminals 12 of the hot cathode fluorescent lamp 10 are illustrated in the through holes 131 of the insulating cap 100. Accordingly, the first connection portions 210 of the two connection terminals 200 move along the two guide grooves 121 to the right side in the drawing. At this time, the deformation portion main bodies of the elastic deformation portions 230 of the two connection terminals 200 are elastically deformed (ie, contracted) in the direction in which the first connection portion and the second connection portion approach each other. The thermal deformation of the hot cathode fluorescent lamp 10 is absorbed by the elastic deformation of the elastic deformation portion 230.

  When the adapter device A and the hot cathode fluorescent lamp 10 are removed from the connection device S, the adapter device A and the hot cathode fluorescent lamp 10 are lifted upward. Then, the bent portions 421 of the two contacts 400 are pressed by the two fitting portions of the insulating cap 100 of the adapter device A and the second connection portions 220 of the two connection terminals 200, respectively. As a result, the contact portions 420 of the contact 400 are elastically deformed outward.

  When the fitting part and the second connection part 220 get over the bent part 421, the adapter device A is removed from the connection device S.

  In this way, when the hot cathode fluorescent lamp 10 and the connection device S are electrically and mechanically connected using the adapter device A, the first connection portions 210 of the two connection terminals 200 are connected to the hot cathode fluorescent lamp 10. The hot cathode fluorescent lamp 10 is connected to the two lead terminals 12 electrically and mechanically, and the second connection part 220 of the connection terminal 200 is sandwiched between the two contacts 400 of the connection device S. Even if thermal expansion or thermal contraction occurs, the elastic deformation portion 230 of the connection terminal 200 expands or contracts with the thermal expansion or thermal contraction, and absorbs the thermal expansion or thermal contraction. Therefore, as in the conventional example, the end portion of the lamp main body 11 of the hot cathode fluorescent lamp 10 and the lead terminal 12 are pressed against or peeled off from the adapter device A attached to the connection device S by thermal expansion or contraction. Therefore, the load applied to the hot cathode fluorescent lamp 10 during thermal expansion or contraction can be reduced.

  In addition, the two connection terminals 200 and the two lead terminals 12 of the hot cathode fluorescent lamp 10 are insulated by the insulating cap 100. For this reason, when the elastic deformation portion 230 of the connection terminal 200 is elastically deformed, one connection terminal 200 contacts the other connection terminal 200 or the lead terminal 12, or the other connection terminal 200 is one connection terminal 200. Alternatively, contact with the lead terminal 12 can be prevented.

  Further, the fitting portions on both sides of the cap portion 110 of the adapter device A and the two second connection portions 220 fixed to the fitting portions are each substantially semicircular, and the two contacts 400 are bent. Between the part 421 and the housing recesses 321, 351, 361, and 371 of the body 300, it is sandwiched so as to be able to rotate in a fixed amount in the circumferential direction. Therefore, when the two lead terminals 12 on one side and the two lead terminals 12 on the other side of the hot cathode fluorescent lamp 30 are not substantially parallel (that is, the two lead terminals 12 on one side are not on the other side). 8 (b), the adapter device A connected to the one lead terminal 12 is rotated as it is, as shown in FIG. 8B. The fitting part and the second connection part 220 are sandwiched between the bent part 421 of the two contacts 400 and the housing recesses 321, 351, 361, 371 of the body 300, and the two second connection parts 220 are held. Can be brought into contact with the two bent portions 421, respectively. Therefore, even in the above-described rotation state, it is possible to ensure electrical connection between the second connection portions 220 of the two connection terminals 200 and the bent portions 421 of the two contacts 400 and one side. As in the case where the two lead terminals 12 are directly connected to the two contacts 400, it is possible to prevent a load from being applied to the joint portion between the lead terminal 12 and the lamp main body 11.

  For the adapter device A, at least two connection members for connecting an electronic component having at least two lead terminals and a connection device for the same component having at least two contacts, respectively, between the connection members Insulating means for insulating, the connection member being electrically and mechanically connected to the lead terminal, and a distance from the first connection portion in the length direction of the electronic component. The second connecting portion that is located at a distance and can be electrically and mechanically connected to the contact, and the heat in the length direction of the electronic component provided between the first and second connecting portions. Each having an elastically deformable portion that can be elastically deformed in response to expansion or thermal contraction, and the insulating means includes at least a first insulating portion disposed between the first connecting portions of the connecting member. As long as the design can be changed arbitrarily It is a function.

  The insulating cap 100 is used as an insulating means for insulating between the two connection terminals 200. However, the insulation cap 100 is disposed at least between the first connection portions 210 of the two connection terminals 200 to insulate the first connection portion 210. As long as it has the 1st insulating part which can do, what kind of thing may be used.

  Therefore, the insulating means may further include a second insulating portion disposed between the elastic deformation portions 230 in addition to the first insulating portion. In this case, the first and second insulating portions can be separated from each other. The insulating means may further include a third insulating portion disposed between the second connecting portions 220 in addition to the first and second insulating portions. Also in this case, the first, second, and third insulating portions can be separated from each other, or only each insulating portion can be separated from other insulating portions. For example, the third insulating part can be separated from the first and second insulating parts.

  In the above embodiment, the first insulating portion corresponds to the tip portion of the flat plate portion 120, but is not limited thereto. Similarly, although the base end portion of the pair of protrusions 130 and the flat plate portion 120 corresponds to the second insulating portion and the cap portion 110 corresponds to the third insulating portion, the present invention is not limited to this.

  The protrusion 111a functions as a rotation restricting means that restricts the rotation of the adapter device A by a predetermined amount or more by being inserted into the hole 381 with play. However, the protrusion 111a is arbitrarily designed as long as the same function is achieved. It is possible to change. For example, when a protrusion is provided on the support portion 380, the rotation restricting means may be a long groove or a long hole provided in the circumferential direction on the outer peripheral surface of the cap portion 110. Note that at least one protrusion 111a may be provided.

  The design of the guide groove 121 can be changed to other guide means capable of guiding the following first connection portion. For example, a pair of ridges 111 are provided on the flat plate portion 120, and a guide rail or the like that guides the following first connection portion.

  The first connecting portion 210 can be arbitrarily designed as long as it can be electrically and mechanically connected to the lead terminal. For example, the first connecting portion can be a rod-like body, a linear plate body, or the like. In addition, as a method of electrically and mechanically connecting the first connection portion to the lead terminal, crimping or the like can be used in addition to soldering or welding, but is not limited thereto.

  The second connecting portion 220 is a substantially semicircular arc plate, but can be arbitrarily designed as long as it can be electrically and mechanically connected to the contact. For example, the second connecting portion can also be a rod-like body, a linear plate body, or the like. In addition, the 2nd connection part does not need to be arrange | positioned along the main-body part of an electronic component.

  In addition, although the second connecting portion is fixed by being fitted to the fitting portion of the cap portion 110, the design can be changed to be fixed to the third insulating portion by other methods. . For example, while providing a hole or a convex part in a 2nd connection part, the convex part or hole which fits into the said hole or convex part can be provided in a 3rd insulating part. It is also possible to fit the second connection part itself into a hole or a recess provided in the third insulating part. In addition, the second connection portion can be fixed to the third insulating portion by bonding or the like. Note that the second connection portion may not be fixed to the third insulating portion.

  The elastic deformation part 230 can be arbitrarily designed as long as it can be deformed in accordance with the thermal expansion or contraction of the electronic component. For example, the elastically deformable portion may have a leaf spring shape or a coil spring shape bent into a substantially U shape or V shape in side view, a substantially U shape or V shape in cross section.

  The connection device S can be arbitrarily designed as long as it includes at least two contacts that are electrically and mechanically connected to the second connection portion of the connection member.

  The contact 400 may have a shape in which the upper end portion is bifurcated and only the second connection portion is sandwiched. In the case where the second connection portion and the third insulating portion are sandwiched by two contacts, the configuration is not limited to the above-described embodiment, and the design can be arbitrarily changed as long as the same function can be realized. .

  The body 300 can be omitted.
