Description

本発明は、電子機器に含まれる複数の電子部品を電気的に接続する端子台に関する。   The present invention relates to a terminal block for electrically connecting a plurality of electronic components included in an electronic device.

従来から、溶接工程を行うことにより複数の電子部品を互いに電気的に接続した電子機器が知られている(下記特許文献1参照)。図10、図11に、この電子機器の一例であるDC−DCコンバータの一部を示す。同図に示すごとく、この電子機器9は、電子部品としてリアクトル91と複数のダイオード92とを備える。   Conventionally, an electronic device in which a plurality of electronic components are electrically connected to each other by performing a welding process is known (see Patent Document 1 below). 10 and 11 show a part of a DC-DC converter which is an example of the electronic apparatus. As shown in the figure, the electronic device 9 includes a reactor 91 and a plurality of diodes 92 as electronic components.

個々のダイオード92は、アノード端子93及びカソード端子94を備える。これらの端子93,94の先端に溶接部930,940が形成されている。溶接部930,940は、リアクトル91の軸線方向(A方向;図11参照)に突出している。
また、リアクトル91には、溶接部930,940と同一方向に突出した被溶接部910が形成されている。
Each diode 92 includes an anode terminal 93 and a cathode terminal 94. Welded portions 930 and 940 are formed at the tips of these terminals 93 and 94. The welds 930 and 940 protrude in the axial direction of the reactor 91 (direction A; see FIG. 11).
In addition, the reactor 91 is formed with a welded portion 910 that protrudes in the same direction as the welded portions 930 and 940.

図11に示すごとく、溶接工程を行う際には、アノード端子93の溶接部930と、リアクトル91の被溶接部910とを重ね合わせ、溶接具95によって挟むと共に、溶接電流Iを流して抵抗熱を発生させる。この抵抗熱によって、溶接部930と被溶接部910とを溶接する。   As shown in FIG. 11, when performing the welding process, the welded portion 930 of the anode terminal 93 and the welded portion 910 of the reactor 91 are overlapped and sandwiched by the welding tool 95, and the welding current I is passed to cause resistance heat. Is generated. The welded part 930 and the welded part 910 are welded by this resistance heat.

また、ダイオード92のカソード端子94(図10参照)の溶接部940には、図示しない別の電子部品の電極端子が溶接される。このように、複数の溶接部930,940に抵抗溶接を行うことにより、ダイオード92やリアクトル91等の電子部品を互いに電気的に接続し、電子回路を構成している。   In addition, an electrode terminal of another electronic component (not shown) is welded to the welding portion 940 of the cathode terminal 94 (see FIG. 10) of the diode 92. In this way, by performing resistance welding on the plurality of welded portions 930 and 940, electronic components such as the diode 92 and the reactor 91 are electrically connected to each other to constitute an electronic circuit.

なお、電子機器9を製造する際には、1個の溶接具95を使って、溶接部930,940を1個ずつ順番に溶接する。すなわち、ある溶接部930aに溶接工程を行った後、溶接具95を別の溶接部930bに移動させ、この溶接部930bを溶接する。これを順次行うことにより、全ての溶接部930,940を溶接する。   When manufacturing the electronic device 9, the welding portions 930 and 940 are sequentially welded one by one using one welding tool 95. That is, after performing a welding process on a certain welded part 930a, the welding tool 95 is moved to another welded part 930b, and this welded part 930b is welded. By sequentially performing this, all the welds 930 and 940 are welded.

特開2003−23772号公報Japanese Patent Laid-Open No. 2003-23772

しかしながら、従来の電子機器9は、複数の溶接部930,940が電子機器9内に分散配置されているため、溶接工程を行う際に、溶接具95の移動距離が長くなるという問題があった。また、溶接具95を様々な方向へ移動させなければならないため、制御が難しくなると共に、移動時間もかかるという問題があった。   However, the conventional electronic device 9 has a problem that the moving distance of the welding tool 95 becomes long when the welding process is performed because the plurality of welded portions 930 and 940 are dispersedly arranged in the electronic device 9. . Further, since the welding tool 95 has to be moved in various directions, there is a problem that it is difficult to control and it takes a moving time.

例えば、ある溶接部930a(図10参照)と別の溶接部930bとを連続して溶接する際には、溶接具95を移動させる際に、溶接具95が溶接部930a,930b等に引っ掛からないようにする必要がある。そのため、例えば、溶接部930aと被溶接部910aとを溶接具95で挟んで溶接した後、溶接具95を開き、上記軸線方向(A方向)に溶接具95を一旦引き上げ、別の溶接部930bの上方まで移動させる必要がある。続いて、溶接具95を上記軸線方向から上記溶接部930bに接近させて、溶接部930bと被溶接部910bとを挟持する必要がある。   For example, when welding a welded part 930a (see FIG. 10) and another welded part 930b continuously, the welder 95 is not caught by the welded parts 930a, 930b, etc. when the welder 95 is moved. It is necessary to do so. Therefore, for example, after the welded part 930a and the welded part 910a are sandwiched and welded by the welding tool 95, the welding tool 95 is opened, the welding tool 95 is once pulled up in the axial direction (A direction), and another welded part 930b It is necessary to move to above. Subsequently, it is necessary to bring the welding tool 95 close to the welded part 930b from the axial direction so as to sandwich the welded part 930b and the welded part 910b.

このように従来の電子機器9は、複数の溶接部930,940を溶接する際に、溶接具95に複雑な動き方をさせる必要があった。また、溶接部930,940間の移動距離も長かった。そのため、溶接工程を行いにくく、時間もかかるという問題があった。   As described above, the conventional electronic device 9 needs to make the welding tool 95 move in a complicated manner when welding the plurality of welded portions 930 and 940. Moreover, the moving distance between the welds 930 and 940 was also long. Therefore, there is a problem that it is difficult to perform the welding process and takes time.

この問題は、複数の電子部品92,91を直接、溶接している限り、容易に解決できない。例えば、アノード端子93の溶接部930とカソード端子94の溶接部940とを接近配置させると、溶接具95の移動距離を短くすることができるが、カソード端子94がアノード端子93やリアクトル91に接触して短絡する可能性がある。そのため、複数の電子部品を直接、溶接するのではなく、別の部品、例えば端子台を電子機器内に設けることにより、複数の溶接部930,940を、短絡することなく近接配置させ、溶接工程を容易に行えるようにすることが望まれていた。   This problem cannot be easily solved as long as the plurality of electronic components 92 and 91 are directly welded. For example, when the welded part 930 of the anode terminal 93 and the welded part 940 of the cathode terminal 94 are arranged close to each other, the moving distance of the welding tool 95 can be shortened, but the cathode terminal 94 contacts the anode terminal 93 and the reactor 91. May cause a short circuit. Therefore, rather than directly welding a plurality of electronic components, by providing another component, for example, a terminal block, in the electronic device, the plurality of welded portions 930 and 940 are arranged close to each other without being short-circuited, and the welding process It has been desired to make it easy to perform.

本発明は、かかる背景に鑑みてなされたもので、電子部品の溶接工程を容易に行うことができる端子台を提供しようとするものである。   The present invention has been made in view of such a background, and an object of the present invention is to provide a terminal block capable of easily performing a welding process of electronic components.

個々の上記溶接部に、上記被溶接電子部品の電極端子を、上記複数の溶接部の立設方向と配列方向との双方に直交する幅方向から重ね合わせて溶接するよう構成され、
上記封止部材は、上記締結板部が露出する露出面を備えた封止本体部を有し、上記幅方向において、上記被溶接電子部品の電極端子と、上記溶接部と、上記封止本体部とがこの順に配置され、上記複数の溶接部と上記封止本体部との間に、上記配列方向に沿った所定の隙間が形成されており、
上記バスバーは、上記基板部と上記締結板部との間を繋ぐ連結板部を備え、上記幅方向における上記基板部の一端から上記溶接部が立設し、上記幅方向における上記基板部の他端から上記連結板部が上記溶接部の立設方向と同一方向に立設し、上記締結板部は上記連結板部と直交した状態で該連結板部に接続していることを特徴とする端子台にある(請求項1)。
One aspect of the present invention is a terminal block that is provided inside an electronic device including a plurality of electronic components and electrically connects the plurality of electronic components,
A plurality of bus bars comprising a substrate portion, a welded portion erected from the substrate portion in the plate thickness direction of the substrate portion, and a fastening plate portion conducted to the substrate portion;
It is made of an insulating material, and includes a sealing member that seals the plurality of bus bars with the welded portion and the fastening plate portion exposed.
The plurality of welds are arranged in a row in a comb shape,
The plurality of electronic components include a fastened electronic component whose electrode terminal is fastened to the fastening plate portion by a fastening member, and a welded electronic component welded to the welded portion,
The electrode terminals of the electronic parts to be welded are individually welded to the individual welded portions by overlapping them from the width direction perpendicular to both the standing direction and the arrangement direction of the plurality of welded portions,
The sealing member includes a sealing main body having an exposed surface from which the fastening plate is exposed, and in the width direction, the electrode terminal of the electronic component to be welded, the welding portion, and the sealing main body. Parts are arranged in this order, and a predetermined gap along the arrangement direction is formed between the plurality of welded parts and the sealing main body part ,
The bus bar includes a connecting plate portion that connects the substrate portion and the fastening plate portion, and the welded portion is erected from one end of the substrate portion in the width direction, and other than the substrate portion in the width direction. The connecting plate portion is erected from the end in the same direction as the standing direction of the welded portion, and the fastening plate portion is connected to the connecting plate portion in a state orthogonal to the connecting plate portion.

上記端子台においては、上記複数の溶接部を櫛歯状に一列に配列してある。そして、上記被溶接電子部品の電極端子を、上記幅方向から重ね合わせて溶接するよう構成してある。また、複数の溶接部と上記封止本体部との間に、上記配列方向に沿った所定の隙間を形成してある。
このようにすると、複数の溶接部を溶接する工程を容易に行えるようになる。すなわち、上記構成にすると、溶接工程を行う際に、一対の溶接具を用意し、この一対の溶接具のうち一方の溶接具を上記隙間に挿入すると共に、該一方の溶接具と他方の溶接具との間で、上記溶接部と上記電極端子とを上記幅方向に挟持し、抵抗溶接を行うことができる。そして、1個の溶接部を溶接した後、溶接具を開き、溶接具を上記立設方向へ移動させることなく上記配列方向へ移動させ、続いて、隣にある別の溶接部を溶接することができる。この工程を繰り返すことにより、全ての溶接部を溶接することができる。このように、溶接具を立設方向へ移動させることなく、一方向(配列方向)へ移動させつつ溶接を行えるので、溶接具の動き方を簡素にすることができると共に、溶接具の移動時間を短くすることが可能になる。
In the terminal block, the plurality of welds are arranged in a row in a comb shape. And it is comprised so that the electrode terminal of the said to-be-welded electronic component may be piled up and welded from the said width direction.

If it does in this way, the process of welding a some welding part can be performed now easily. That is, with the above configuration, when performing the welding process, a pair of welding tools are prepared, and one of the pair of welding tools is inserted into the gap, and the one welding tool and the other welding tool are inserted. The welding part and the electrode terminal can be sandwiched in the width direction with the tool, and resistance welding can be performed. And after welding one weld, open the welding tool, move the welding tool in the arrangement direction without moving it in the standing direction, and then weld another welding part next to it Can do. By repeating this process, all the welds can be welded. Thus, since welding can be performed while moving in one direction (arrangement direction) without moving the welding tool in the standing direction, the movement of the welding tool can be simplified and the movement time of the welding tool can be achieved. Can be shortened.

また、上記端子台は、複数のバスバーを上記封止部材によって封止しているため、この複数のバスバーをしっかりと固定することができる。そのため、個々のバスバーに含まれる溶接部が互いに近接する位置に配置されていても、溶接部同士が接触して短絡する等の不具合が生じにくい。   Moreover, since the said terminal block has sealed the several bus bar with the said sealing member, this several bus bar can be fixed firmly. Therefore, even if the welds included in the individual bus bars are arranged at positions close to each other, problems such as short-circuiting due to contact between the welds hardly occur.

以上のごとく、本例によれば、電子部品の溶接工程を容易に行うことができる端子台を提供することができる。   As described above, according to this example, it is possible to provide a terminal block that can easily perform a welding process of electronic components.

The cathode terminals of the two diodes 24a and 24b are connected to the second electrode terminal 23b, respectively. The second electrode terminal 23b is located between the first electrode 23a and the third electrode 23c. By doing so, the direction of the input current i flowing through the first electrode terminal 23a and the third electrode terminal 23c and the direction of the output current 2i flowing through the second electrode terminal 23b are reversed, and these electrode terminals 23a-23c The inductance generated between them is reduced.

図2に示すごとく、第1バスバー3aは、第1溶接部33aと、第3溶接部33cと、第4溶接部33dと、第6溶接部33fとの、4本の溶接部33を備える。Y方向における、第1溶接部33aと第3溶接部33cとの間隔D1は、第4溶接部33dと第6溶接部33fとの間隔D3と同程度である。第3溶接部33cと第4溶接部33dとの間隔D2は、上記間隔D1,D3よりも狭い。
また、第2バスバー3bは、第7溶接部33gと、第9溶接部33iと、第10溶接部33jと、第12溶接部33mとの、4本の溶接部33を備える。
As shown in FIG. 2, the 1st bus-bar 3a is provided with the four welding parts 33 of the 1st welding part 33a, the 3rd welding part 33c, the 4th welding part 33d, and the 6th welding part 33f. An interval D1 between the first welded portion 33a and the third welded portion 33c in the Y direction is substantially the same as an interval D3 between the fourth welded portion 33d and the sixth welded portion 33f. An interval D2 between the third welded portion 33c and the fourth welded portion 33d is narrower than the intervals D1 and D3.
Moreover, the 2nd bus-bar 3b is provided with the four welding parts 33 of the 7th welding part 33g, the 9th welding part 33i, the 10th welding part 33j, and the 12th welding part 33m.

第3バスバー3cは、第2溶接部33bと、第5溶接部33eと、第8溶接部33hと、第11溶接部33kとの、4本の溶接部33を備える。第2溶接部33bは、第1溶接部33aと第3溶接部33cとの間に位置し、第5溶接部33eは、第4溶接部33dと第6溶接部33fとの間に位置する。同様に、第8溶接部33hは、第7溶接部33gと第9溶接部33iの間に位置し、第11溶接部33kは、第10溶接部33jと第12溶接部33mとの間に位置する。   The third bus bar 3c includes four welded portions 33 including a second welded portion 33b, a fifth welded portion 33e, an eighth welded portion 33h, and an eleventh welded portion 33k. The second weld 33b is located between the first weld 33a and the third weld 33c, and the fifth weld 33e is located between the fourth weld 33d and the sixth weld 33f. Similarly, the eighth weld 33h is located between the seventh weld 33g and the ninth weld 33i, and the eleventh weld 33k is located between the tenth weld 12j and the twelfth weld 33m. To do.

図3に示すごとく、第1ダイオードモジュール21aの第1電極端子23aは第1溶接部33aに溶接され、第2電極端子23bは第2溶接部33bに溶接される。また、第3電極端子23cは第3溶接部33cに溶接される。他のダイオードモジュール21の電極端子23も同様に、溶接部33d〜33mに溶接される。   As shown in FIG. 3, the 1st electrode terminal 23a of the 1st diode module 21a is welded to the 1st welding part 33a, and the 2nd electrode terminal 23b is welded to the 2nd welding part 33b. The third electrode terminal 23c is welded to the third welding portion 33c. Similarly, the electrode terminals 23 of the other diode modules 21 are also welded to the welded portions 33d to 33m.

上述したように、第1バスバー3aの締結板部34aは、トランス20a(図8参照)の一方の二次コイル71に接続され、第2バスバー3bの締結板部34bは他方の二次コイル72に接続される。二次コイル71,72に発生する電流i(二次電流)は、ブリッジ回路70の動作に伴って交互に向きが替わる。この電流iを、ダイオードモジュール21によって整流している。   As described above, the fastening plate portion 34a of the first bus bar 3a is connected to one secondary coil 71 of the transformer 20a (see FIG. 8), and the fastening plate portion 34b of the second bus bar 3b is connected to the other secondary coil 72. Connected to. The direction of the current i (secondary current) generated in the secondary coils 71 and 72 alternates with the operation of the bridge circuit 70. This current i is rectified by the diode module 21.

電流iの流れを、第1ダイオードモジュール21a(図3参照)を例にとって説明する。第1ダイオードモジュール21aのダイオード24に対して順方向に電圧が加わる場合は、二次コイル71から電流iが締結板部34aに流れ込む。電流iは、連結板部32、基板部31(図2参照)を流れ、さらに溶接部33a,33c、第1モジュール21aの電極端子23a,23cを流れる。その後、電流iはダイオード24(図9参照)を流れ、第2電極端子23bから出力される。そして電流iは、第2電極端子23bから第2溶接部33bを通り、第3バスバー3cの基板部31および連結板部32(図2参照)を流れて、締結板部34cから出力される。   The flow of the current i will be described by taking the first diode module 21a (see FIG. 3) as an example. When a voltage is applied in the forward direction to the diode 24 of the first diode module 21a, the current i flows from the secondary coil 71 into the fastening plate portion 34a. The current i flows through the connecting plate portion 32 and the substrate portion 31 (see FIG. 2), and further flows through the welding portions 33a and 33c and the electrode terminals 23a and 23c of the first module 21a. Thereafter, the current i flows through the diode 24 (see FIG. 9) and is output from the second electrode terminal 23b. Then, the current i passes from the second electrode terminal 23b through the second welding portion 33b, flows through the substrate portion 31 and the connecting plate portion 32 (see FIG. 2) of the third bus bar 3c, and is output from the fastening plate portion 34c.

本例の作用効果について説明する。図3に示すごとく、本例では、複数の溶接部33を櫛歯状に一列に配列した。そして、被溶接電子部品21の電極端子23を、Z方向から重ね合わせて溶接するよう構成した。また、複数の溶接部33と封止本体部40との間に、Y方向に沿った所定の隙間dを形成した。
このようにすると、複数の溶接部33を溶接する工程を容易に行えるようになる。すなわち、溶接工程を行う際には、図5に示すごとく、一対の溶接具6a,6bを用意し、一方の溶接具6aを隙間dに挿入すると共に、該一方の溶接具6aと他方の溶接具6bとの間で、溶接対8をZ方向に挟持し、抵抗溶接を行うことができる。そして、一個の溶接対8を溶接した後、図6に示すごとく、溶接具6a,6bを開き、溶接具6a,6bをX方向へ移動させることなくY方向へ移動させ、続いて、隣にある別の溶接対8を溶接することができる。この工程を繰り返すことにより、全ての溶接対8を溶接することができる。このように、溶接具6a,6bをX方向へ移動させることなく、一方向(Y方向)へ移動させつつ溶接を行えるので、溶接具6a,6bの動き方を簡素にすることができると共に、溶接具6a,6bの移動時間を短くすることが可能になる。
The effect of this example will be described. As shown in FIG. 3, in this example, a plurality of welds 33 are arranged in a row in a comb shape. And the electrode terminal 23 of the to-be-welded electronic component 21 was comprised so that it might overlap and weld from a Z direction. Further, a predetermined gap d along the Y direction was formed between the plurality of welds 33 and the sealing main body 40.
If it does in this way, the process of welding the some welding part 33 can be performed now easily. That is, when performing the welding process, as shown in FIG. 5, a pair of welding tools 6a and 6b are prepared, and one welding tool 6a is inserted into the gap d and the welding tool 6a and the other welding tool are inserted. The welding pair 8 can be clamped in the Z direction between the tool 6b and resistance welding can be performed. Then, after welding one welded pair 8, as shown in FIG. 6, the welding tools 6a and 6b are opened, and the welding tools 6a and 6b are moved in the Y direction without moving in the X direction. One other weld pair 8 can be welded. By repeating this process, all the welding pairs 8 can be welded. In this way, welding can be performed while moving the welding tools 6a and 6b in one direction (Y direction) without moving the welding tools 6a and 6b in the X direction, so that the manner of movement of the welding tools 6a and 6b can be simplified. It becomes possible to shorten the movement time of the welding tools 6a and 6b.

また、本例の端子台1は、複数のバスバー3を封止部材4によって封止しているため、これら複数のバスバー3をしっかりと固定することができる。そのため、個々のバスバー3に含まれる溶接部33が互いに近接する位置に配置されていても、溶接部33同士が接触して短絡する等の不具合が生じにくい。   Moreover, since the terminal block 1 of this example has sealed the several bus-bar 3 with the sealing member 4, these several bus-bar 3 can be fixed firmly. Therefore, even if the welding parts 33 included in the individual bus bars 3 are arranged at positions close to each other, problems such as short-circuiting due to contact between the welding parts 33 are unlikely to occur.

また、図4に示すごとく、バスバー3は連結板部32を備える。Z方向における基板部31の一端311から溶接部33が立設し、Z方向における基板部31の他端312から、連結板部32が、溶接部33の立設方向(X方向)と同一方向に立設している。そして、締結板部34は連結板部32と直交した状態で連結板部32に接続している。
このようにすると、溶接部33を溶接する工程と、締結板部34を締結する工程とを、それぞれ行いやすくなる。すなわち、バスバー3を上記形状にすると、X方向に対して締結板部34を垂直に向けることができる。そのため、締結工程を行う際には、被締結電子部品20の電極端子22を締結板部34に重ね合わせ、雄螺子部51をX方向から締結板部34に接近させて、雄螺子部51を雌螺子部52に螺合させることにより、これら電極端子22と締結板部34とを締結することができる。また、溶接工程を行う際には、溶接具6a,6bをX方向から溶接部33に接近させ、この溶接具6a,6bによって溶接対8を挟持し、溶接を行うことができる。このように、溶接具6と雄螺子部51とを、それぞれ同一方向(X方向)から接近させることができるため、溶接工程および締結工程を行いやすくなる。
Further, as shown in FIG. 4, the bus bar 3 includes a connecting plate portion 32. The welded portion 33 is erected from one end 311 of the substrate portion 31 in the Z direction, and the connecting plate portion 32 is in the same direction as the erected direction (X direction) of the welded portion 33 from the other end 312 of the substrate portion 31 in the Z direction. Is standing. The fastening plate portion 34 is connected to the connecting plate portion 32 in a state orthogonal to the connecting plate portion 32.
If it does in this way, it will become easy to perform the process of welding the welding part 33, and the process of fastening the fastening plate part 34, respectively. That is, when the bus bar 3 has the above shape, the fastening plate portion 34 can be directed perpendicular to the X direction. Therefore, when performing the fastening process, the electrode terminal 22 of the electronic component 20 to be fastened is superposed on the fastening plate portion 34, the male screw portion 51 is brought close to the fastening plate portion 34 from the X direction, and the male screw portion 51 is moved. The electrode terminal 22 and the fastening plate portion 34 can be fastened by being screwed to the female screw portion 52. Moreover, when performing a welding process, the welding tools 6a and 6b can be approached to the welding part 33 from a X direction, the welding pair 8 can be clamped by these welding tools 6a and 6b, and welding can be performed. Thus, since the welding tool 6 and the male screw part 51 can be made to approach from the same direction (X direction), respectively, it becomes easy to perform a welding process and a fastening process.

また、図7に示すごとく、本例の端子台1は、電子機器10を収納する収納ケース11の固定壁部116に、溶接部33を固定壁部116の法線方向(X方向)に向けた状態で固定されている。そして、図4に示すごとく、固定壁部116と締結板部34との間に、雌螺子部52が配置されている。
このようにすると、固定壁部116と締結板部34との間の空間Sに雌螺子部52を配置できるので、この空間Sを有効利用することができる。これにより、端子台1をコンパクトに形成することが可能になる。
Further, as shown in FIG. 7, the terminal block 1 of this example is directed to the fixed wall portion 116 of the storage case 11 that stores the electronic device 10, and the welded portion 33 is directed to the normal direction (X direction) of the fixed wall portion 116. It is fixed in the state. As shown in FIG. 4, the female screw portion 52 is disposed between the fixed wall portion 116 and the fastening plate portion 34.
If it does in this way, since female screw part 52 can be arranged in space S between fixed wall part 116 and fastening plate part 34, this space S can be used effectively. Thereby, it becomes possible to form the terminal block 1 compactly.

また、図4に示すごとく、本例では、X方向から見た場合に、被溶接電子部品(ダイオードモジュール21)の少なくとも一部が封止部材4と重なるように構成されている。
このようにすると、X方向から見た場合における、被溶接電子部品21と封止部材4とが占める面積を少なくすることができる。これにより、電子機器10を小型化することが可能になる。
Further, as shown in FIG. 4, in this example, the electronic component to be welded (diode module 21) is configured to overlap the sealing member 4 when viewed from the X direction.
If it does in this way, the area which the to-be-welded electronic component 21 and the sealing member 4 occupy when it sees from a X direction can be decreased. Thereby, the electronic device 10 can be reduced in size.

以上のごとく、本例によれば、電子部品の溶接工程を容易に行うことができる端子台を提供することができる。   As described above, according to this example, it is possible to provide a terminal block that can easily perform a welding process of electronic components.
