Description

端子台および、これを用いた照明器具Terminal block and lighting apparatus using the same
　本発明は、端子台および、端子台を用いた照明器具に関するものである。 The present invention relates to a terminal block and a luminaire using the terminal block.
　従来、電線挿通孔を有するハウジングと、このハウジングに収納され電線挿通孔から挿通された電線が接続される導電ブロックとを備える端子台がある。一般的に端子台には複数の導電ブロックが収納されており、この複数の導電ブロックのうち１つは、アース電線が接続される。そして、例えば、文献１（日本国公開特許公報第平５－２７５１３２号）に示すように、アース電線が接続される導電ブロックの一部（アース端子部）がハウジングから突出し、端子台が取り付けられる取り付け板に形成された端子挿通孔の内周面にアース端子部を接触させることで、取り付け板のアース（接地）を行っている。 Conventionally, there is a terminal block including a housing having a wire insertion hole, and a conductive block to which a wire accommodated in the housing and inserted through the wire insertion hole is connected. Generally, a plurality of conductive blocks are accommodated in the terminal block, and one of the plurality of conductive blocks is connected to a ground wire. Then, for example, as shown in Document 1 (Japanese Patent Application Laid-Open No. 5-275132), a part (ground terminal portion) of the conductive block to which the grounding wire is connected protrudes from the housing, and the terminal block is attached The grounding terminal portion is grounded by bringing the ground terminal portion into contact with the inner peripheral surface of the terminal insertion hole formed in the mounting plate.
　一般的にアース端子部は、薄い平板状に形成されている。したがって、アース端子部と端子挿通孔の内周面とを接触させるためには、アース端子部の断面と略同じ大きさの端子挿通孔を形成する必要がある。そのため、端子挿通孔の開口寸法は、高い精度が求められる。特に平板状に形成されたアース端子部の厚みに対応させた場合、端子挿通孔の開口寸法は小さくなることが多く、端子挿通孔を形成するのが困難であった。 Generally, the ground terminal portion is formed in a thin flat plate shape. Therefore, in order to bring the ground terminal portion into contact with the inner peripheral surface of the terminal insertion hole, it is necessary to form a terminal insertion hole having substantially the same size as the cross section of the ground terminal portion. Therefore, high accuracy is required for the opening dimension of the terminal insertion hole. In particular, when the thickness of the ground terminal portion formed in a flat plate shape is matched, the opening size of the terminal insertion hole often becomes small, and it is difficult to form the terminal insertion hole.
　本発明は、上記事由に鑑みてなされたものであり、その目的は、端子挿通孔の形成を容易にし、確実に端子挿通孔の内周面に接触させることができる端子台および、これを用いた照明器具を提供することにある。 The present invention has been made in view of the above circumstances, and its object is to facilitate the formation of a terminal insertion hole and to reliably contact the inner peripheral surface of the terminal insertion hole, and a terminal block therefor To provide a lighting fixture.

The configuration of the terminal block 10 according to the present embodiment will be described with reference to FIGS.
　本実施形態の端子台１０は、ハウジング１と、ハウジング１に収納される３つの導電ブロック２とを備え、例えば、照明器具に取り付けられる。以降、図１に示した上下・左右方向を、本実施形態の端子台１０における上下・左右方向とし、図１で定義した上下・左右方向を含む平面と直交する方向を本実施形態の端子台１０における前後方向として説明する。 The terminal block 10 of the present embodiment includes a housing 1 and three conductive blocks 2 housed in the housing 1, and is attached to, for example, a luminaire. Hereinafter, the vertical and horizontal directions shown in FIG. 1 are referred to as the vertical and horizontal directions in the terminal block 10 of the present embodiment, and the direction perpendicular to the plane including the vertical and horizontal directions defined in FIG. It will be described as the front-rear direction at 10.
　ハウジング１は、下面が開口した箱状の本体１１と、下方から本体１１の開口を覆うように本体１１に結合されるカバー１２とで構成され、内部に各導電ブロック２が収納される収納部１４を備える。本体１１の前面には、３つの係止孔１１１が左右方向に並んで形成されている。また、カバー１２の前面には、各係止孔１１１に係止される凸部１２１が左右方向に並設されている。そして、係止孔１１１の各々に、凸部１２１の各々が係止されることで、本体１１とカバー１２とが結合される。 The housing 1 includes a box-like main body 11 whose lower surface is open, and a cover 12 coupled to the main body 11 so as to cover the opening of the main body 11 from the lower side, and a storage portion in which each conductive block 2 is stored 14 is provided. Three locking holes 111 are formed in the front surface of the main body 11 side by side in the left-right direction. Further, on the front surface of the cover 12, convex portions 121 locked in the locking holes 111 are arranged in parallel in the left-right direction. And each of the convex part 121 is latched by each of the locking hole 111, and the main body 11 and the cover 12 are couple | bonded.
　本体１１は、前面に３つの電線挿通部１３が左右方向に並設されている。電線挿通部１３、左右方向に並列して形成された第１の電線挿通孔１３１ａ，第２の電線挿通孔１３１ｂで構成されており、電線挿通部１３の開口形状は、左右方向に並ぶ円形状の第１，第２の電線挿通孔１３１ａ，１３１ｂを組み合わせた形状となっている。そして、第１の電線挿通孔１３１ａに第１の電線が挿通され、第２の電線挿通孔１３１ｂに第２の電線が挿通される。つまり、電線挿通孔１３１（電線挿通部１３）は、電線（例えば、アース線）を挿通させるように構成されている。そして、ハウジング１は、電線挿通孔１３１を有する。 The main body 11 has three electric wire insertion portions 13 arranged in parallel in the left-right direction on the front surface. The wire insertion portion 13 is constituted by a first wire insertion hole 131a and a second wire insertion hole 131b formed in parallel in the left and right direction, and the opening shape of the wire insertion portion 13 is a circular shape aligned in the left and right direction The first and second electric wire insertion holes 131a and 131b are combined. Then, the first electric wire is inserted into the first electric wire insertion hole 131a, and the second electric wire is inserted into the second electric wire insertion hole 131b. That is, the wire insertion hole 131 (the wire insertion portion 13) is configured to insert a wire (for example, a ground wire). Then, the housing 1 has a wire insertion hole 131.
　また、ハウジング１内には、導電ブロック２を収納する収納部１４が形成されている。つまり、導電ブロック２は、ハウジング１に取り付けられるように構成されている。各導電ブロック２は、電線挿通部１３と一対一に対応付けられており、第１，第２の速結端子部２１ａ，２１ｂを有している。つまり、導電ブロック２は、速結端子部２１（２１ａ，２１ｂ）を有する。第１の速結端子部２１ａは、第１の電線挿通孔１３１ａに挿通された第１の電線を鎖錠接続する。ここで、鎖錠接続とは工具を用いずに電線を固定する接続方法を指す。第２の速結端子部２１ｂは、第２の電線挿通孔１３１ｂに挿通された第２の電線を鎖錠接続する。また、第１，第２の速結端子部２１ａ，２１ｂは、互いに連結部２２によって接続されており、同一の電線挿通部１３に挿通される一対の電線（第１，第２の電線）は、導電ブロック２によって電気的に接続される。したがって、例えば第１の電線の一端を電源に接続する場合、第２の電線の一端を他の機器（端子台など）に接続して送り配線することができる。 Further, in the housing 1, a housing portion 14 for housing the conductive block 2 is formed. That is, the conductive block 2 is configured to be attached to the housing 1. Each conductive block 2 is in one-to-one correspondence with the wire insertion portion 13 and has first and second quick connection terminals 21a and 21b. That is, the conductive block 2 has the quick connect terminal portions 21 (21a, 21b).

That is, the housing 1 is configured to be fixed to the structure 3. The structure 3 includes a terminal insertion hole 31 configured to insert the ground terminal portion 24. The ground terminal portion 24 is designed to project from the housing 1 so that the side piece 242 contacts the inner surface of the terminal insertion hole 31 provided in the structure 3 when the housing 1 is fixed to the structure 3 There is. The inner surface of the terminal insertion hole 31 is configured to conduct with the structure 3. Therefore, when the terminal block 10 is attached to the structure 3 and the earth terminal portion 24 and the terminal insertion hole 31 are in contact with each other, the structure 3 can be grounded.
　図７に示す端子台１０を一部破断させた斜視図を用いて、取り付け板（構造物）３への端子台１０の取り付けについて説明する。図７（ａ）は、端子台１０を構造物３へ取り付ける前の状態を示している。図７（ｂ）は、端子台１０を構造物３へ取り付けた後の状態を示しており、アース端子部２４は、構造物３の端子挿通孔３１の内面（内周面）に接触している。 The attachment of the terminal block 10 to the attachment plate (structure) 3 will be described using a perspective view in which the terminal block 10 shown in FIG. 7 is partially broken. FIG. 7A shows the state before the terminal block 10 is attached to the structure 3. FIG. 7B shows the state after the terminal block 10 is attached to the structure 3, and the ground terminal portion 24 contacts the inner surface (inner peripheral surface) of the terminal insertion hole 31 of the structure 3. There is.
　取り付け板３には、図１で定義した前後方向を長手方向とし、長手方向の長さを幅とする開口形状が矩形状の端子挿通孔３１が形成されており、この端子挿通孔３１にアース端子部２４が挿通するように端子台１０が取り付けられる。ここで、アース端子部２４の先端（第１端）２４１ａ側における幅（幅狭部２４６における側片２４２の端部２４２ｃ、２４２ｃ同士の間隔）をＬ１、アース端子部２４の基端（第２端）２４１ｂ側における幅（幅広部２４７における側片２４２の端部２４２ｃ、２４２ｃ同士の間隔）をＬ２とする（図４参照）。ここで、本実施形態におけるアース端子部２４の幅は、図１では前後方向の長さで示し、図３、図４及び図８では、左右方向の長さで示している。また、端子挿通孔３１の図１において前後方向で示している長手方向の長さを幅Ｌ３とする（図４及び図８参照）。本実施形態では、端子挿通孔３１の幅Ｌ３、アース端子部２４において幅狭部２４６が設けられた位置の幅Ｌ１、アース端子部２４において幅広部２４７が設けられた位置の幅Ｌ２の関係が、Ｌ１＜Ｌ３＜Ｌ２となるようにアース端子部２４を形成している。これにより、アース端子部２４を端子挿通孔３１に挿通させる際に、先端（第１端）２４１ａ側の幅Ｌ１は端子挿通孔３１の幅Ｌ３よりも狭いのでアース端子部２４を端子挿通孔３１に挿通しやすくなる。 The mounting plate 3 is formed with a terminal insertion hole 31 having a rectangular opening shape whose longitudinal direction is the front-rear direction defined in FIG. 1 and whose length in the longitudinal direction is a width. The terminal block 10 is attached such that the terminal portion 24 is inserted. Here, the width L1 at the tip (first end) 241a side of the ground terminal portion 24 (the distance between the end portions 242c and 242c of the side pieces 242 in the narrow portion 246) is the base end of the ground terminal portion 24 (second The width on the side of the end 241 b (the distance between the end portions 242 c and 242 c of the side pieces 242 in the wide portion 247) is L 2 (see FIG. 4). Here, the width of the ground terminal portion 24 in the present embodiment is indicated by the length in the front-rear direction in FIG. 1, and is indicated by the length in the left-right direction in FIG. 3, FIG. 4 and FIG. Moreover, let the length of the longitudinal direction shown by the front-back direction in FIG. 1 of the terminal penetration hole 31 be width L 3 (refer FIG. 4 and FIG. 8). In the present embodiment, the relationship between the width L3 of the terminal insertion hole 31, the width L1 of the position where the narrow portion 246 is provided in the ground terminal portion 24, and the width L2 of the position where the wide portion 247 is provided in the ground terminal portion 24 is The ground terminal portion 24 is formed such that L1 <L3 <L2. Thus, when the ground terminal portion 24 is inserted into the terminal insertion hole 31, the width L1 on the tip end (first end) 241a side is narrower than the width L3 of the terminal insertion hole 31, and therefore the ground terminal portion 24 is inserted into the terminal insertion hole 31. It is easy to insert
　さらに、アース端子部２４の基端（第２端）２４１ｂ側の幅（幅広部２４７が設けられた位置の幅）Ｌ２は、端子挿通孔３１の幅Ｌ３よりも広いので、アース端子部２４が端子挿通孔３１に挿通すると、側片２４２の傾斜部２４５（傾斜縁２４５ｃ）が端子挿通孔３１の内周面に当接することとなる。すなわち、端子挿通孔３１への挿入力を増加させることなく、アース端子部２４を端子挿通孔３１の内周面に確実に接触させることができ、取り付け板３をアース（接地）することができる。つまり、アース端子部２４は、第１端２４１ａ側の幅狭部２４６を備える位置における幅Ｌ１が、端子挿通孔３１の幅Ｌ３より小さく構成され、第１端２４１ａで端子挿通孔３１を通過するように構成されている。また、アース端子部２４は、第２端２４１ｂ側の幅広部２４７を備える位置における幅Ｌ２が、端子挿通孔３１の幅Ｌ３より大きく構成されている。そして、アース端子部２４は、第１端２４１ａから第２端２４１ｂに向かって幅Ｌ１から幅Ｌ２の間で幅広になる傾斜部２４５を第１端２４１ａと第２端２４１ｂとの間（幅狭部２４６と幅広部２４７との間）に備える。ここで、Ｌ１、Ｌ２、Ｌ３は、Ｌ１＜Ｌ３＜Ｌ２の関係を満たすため、傾斜部２４５は、幅Ｌ３を有する部分を備えることになる。したがって、アース端子部２４は、第１端２４１ａから第２端２４１ｂに向かう方向に第１端２４１ａを端子挿通孔３１に挿通することで、幅がＬ３となる傾斜部２４５の位置で端子挿通孔３１の内面に接触することができる。 Furthermore, since the width L2 at the base end (second end) 241b side of the ground terminal portion 24 (width at the position where the wide portion 247 is provided) L2 is wider than the width L3 of the terminal insertion hole 31, the ground terminal portion 24 is When the terminal insertion hole 31 is inserted, the inclined portion 245 (inclined edge 245 c) of the side piece 242 comes in contact with the inner peripheral surface of the terminal insertion hole 31. That is, the ground terminal portion 24 can be reliably brought into contact with the inner peripheral surface of the terminal insertion hole 31 without increasing the insertion force into the terminal insertion hole 31, and the mounting plate 3 can be grounded (grounded). . That is, the ground terminal portion 24 is configured such that the width L1 at the position including the narrow portion 246 on the first end 241a side is smaller than the width L3 of the terminal insertion hole 31 and passes through the terminal insertion hole 31 at the first end 241a. Is configured as. Further, the ground terminal portion 24 is configured to have a width L2 larger than the width L3 of the terminal insertion hole 31 at the position where the wide portion 247 on the second end 241b side is provided. Then, the ground terminal portion 24 is configured such that the sloped portion 245, which is widened from the width L1 to the width L2 from the first end 241a to the second end 241b, between the first end 241a and the second end 241b Between the portion 246 and the wide portion 247). Here, since L1, L2, and L3 satisfy the relationship of L1 <L3 <L2, the inclined portion 245 is provided with a portion having a width L3. Therefore, by inserting the first end 241a into the terminal insertion hole 31 in the direction from the first end 241a to the second end 241b, the ground terminal portion 24 is a terminal insertion hole at the position of the inclined portion 245 having a width L3. 31 can be in contact with the inner surface.
　つまり、構造物３のアースを取る場合には、接続端子部２００にアース線を受け、そして、アース端子部２４を構造物３の導電性を備える部位（本実施形態では、端子挿通孔３１の内面）に接触させればよい。あるいは、アース端子部２４を構造物３の導電性を備える部位（本実施形態では、端子挿通孔３１の内面）に接触させたのち、接続端子部２００にアース線を受けてもよい。 That is, when the ground of the structure 3 is to be taken, the connection terminal portion 200 receives the ground wire, and the ground terminal portion 24 is provided with the conductivity of the structure 3 (in this embodiment, The inner surface may be contacted. Alternatively, after the ground terminal portion 24 is brought into contact with the conductive portion of the structure 3 (in the present embodiment, the inner surface of the terminal insertion hole 31), the connection terminal portion 200 may receive the ground wire.
　また、本実施形態のアース端子部２４は、中央片２４１と中央片２４１に対して傾斜した側片２４２とを備えているため、本実施形態のアース端子部２４を用いるときには、従来のアース端子を用いるときに比べ、端子挿通孔３１の短手方向の幅、つまり厚みＬ５（図８における上下方向の長さ；図１における左右方向の長さ；図３及び４における紙面垂直方向の長さ）を大きくすることができる。従来の端子台では、例えば、図１０に示すように、アース端子部２４Ａを平板状に形成した場合、アース端子部２４Ａを端子挿通孔３１ａの内周面に接触させるためには、端子挿通孔３１の短手方向（図１０における上下方向）の幅、つまり厚みＬ４を、アース端子部２４Ａの厚みと略同一にする必要がある。なお、図１０では、端子挿通孔３１ａに対してアース端子部２４Ａを小さく図示している。このように、従来のアース端子部２４Ａでは、アース端子部２４Ａを平板状に形成した場合、取り付け板３に短手方向の幅、つまり厚みＬ４が小さい端子挿通孔３１ａを形成する必要があり、端子挿通孔３１ａの形成が困難であった。つまり、従来の平板状のアース端子部２４Ａを用いる場合では、アース端子部２４Ａを挿通させる端子挿通孔３１はアース端子部２４Ａの板の厚みと同じ厚みで形成される必要があった。 Further, since the ground terminal portion 24 of the present embodiment includes the central piece 241 and the side pieces 242 inclined with respect to the central piece 241, when using the ground terminal portion 24 of the present embodiment, the conventional ground terminal is used. The width of the terminal insertion hole 31 in the lateral direction, that is, the thickness L5 (vertical length in FIG. 8; horizontal length in FIG. 1; length in the vertical direction of the paper surface in FIGS. ) Can be enlarged. In the conventional terminal block, for example, as shown in FIG. 10, when the ground terminal portion 24A is formed in a flat plate shape, in order to make the ground terminal portion 24A contact the inner circumferential surface of the terminal insertion hole 31a, the terminal insertion hole The width in the short direction 31 (vertical direction in FIG. 10), that is, the thickness L4, needs to be substantially the same as the thickness of the ground terminal portion 24A. In FIG. 10, the ground terminal portion 24A is illustrated smaller than the terminal insertion hole 31a. As described above, in the conventional ground terminal portion 24A, when the ground terminal portion 24A is formed in a flat plate shape, it is necessary to form the terminal insertion hole 31a having a small width L4, ie, a small thickness L4, in the mounting plate 3. It was difficult to form the terminal insertion hole 31a. That is, in the case where the conventional flat ground terminal portion 24A is used, the terminal insertion hole 31 through which the ground terminal portion 24A is inserted needs to be formed with the same thickness as the thickness of the plate of the ground terminal portion 24A.
　しかし、本実施形態では図８に示すように、アース端子部２４は、中央片２４１と中央片２４１に対して傾斜した側片２４２とを備えているため、従来のアース端子部２４Ａを形成する平板と同じ厚みの中央片２４１を用いてアース端子部２４を形成しても、アース端子部２４としての厚みを、アース端子部２４Ａを形成する平板の厚みよりも容易に大きくすることができる。そのため、端子挿通孔３１の短手方向（図８における上下方向）における幅、つまり厚みＬ５を従来の端子挿通孔３１の厚みＬ４より大きくしても（Ｌ５＞Ｌ４）、アース端子部２４の幅Ｌ３である部分（本実施形態では、傾斜部２４５）で、アース端子部２４と端子挿通孔３１とを安定に接触させることができる。なお、図８（ａ）では、アース端子部２４を端子挿通孔３１に挿通させる前を表しており、そのため、端子挿通孔３１に対してアース端子部２４を小さく図示している。図８（ｂ）では、アース端子部２４を端子挿通孔３１に挿通させた後を表しており、アース端子部２４と端子挿通孔３１とは接触している。すなわち、アース端子部２４を形成する板の厚みがアース端子部２４ａと同一であっても、側片２４２を備えていることによって、端子挿通孔３１の短手方向の幅、つまり厚みＬ５を大きくすることができ、アース端子部２４を接触させる端子挿通孔３１の形成が容易となる。 However, in the present embodiment, as shown in FIG. 8, since the ground terminal portion 24 includes the central piece 241 and the side piece 242 inclined with respect to the central piece 241, the conventional ground terminal portion 24A is formed. Even if the ground terminal portion 24 is formed using the center piece 241 having the same thickness as that of the flat plate, the thickness as the ground terminal portion 24 can be easily made larger than the thickness of the flat plate forming the ground terminal portion 24A. Therefore, even if the width L5 in the lateral direction (vertical direction in FIG. 8) of the terminal insertion hole 31 is larger than the thickness L4 of the conventional terminal insertion hole 31 (L5> L4), the width of the ground terminal portion 24 The earth terminal portion 24 and the terminal insertion hole 31 can be stably brought into contact with each other at the portion L3 (in the present embodiment, the inclined portion 245). 8A shows the state before the ground terminal portion 24 is inserted into the terminal insertion hole 31. Therefore, the ground terminal portion 24 is shown smaller than the terminal insertion hole 31. FIG. 8B shows a state in which the ground terminal portion 24 is inserted into the terminal insertion hole 31, and the ground terminal portion 24 and the terminal insertion hole 31 are in contact with each other. That is, even if the thickness of the plate forming the ground terminal portion 24 is the same as that of the ground terminal portion 24a, by providing the side piece 242, the width in the lateral direction of the terminal insertion hole 31, that is, the thickness L5 is increased. Thus, the formation of the terminal insertion hole 31 for contacting the ground terminal portion 24 is facilitated.
　また、端子挿通孔３１の幅Ｌ３と、アース端子部２４の幅Ｌ１，Ｌ２との関係が、Ｌ１＜Ｌ３＜Ｌ２であれば、アース端子部２４を端子挿通孔３１の内周面に確実に接触させることができるので、端子挿通孔３１の開口寸法に高い精度が要求されず、端子挿通孔３１の形成がさらに容易となる。 In addition, if the relationship between the width L3 of the terminal insertion hole 31 and the widths L1 and L2 of the ground terminal portion 24 is L1 <L3 <L2, the ground terminal portion 24 is reliably formed on the inner peripheral surface of the terminal insertion hole 31. Since the contact can be made, the opening dimension of the terminal insertion hole 31 is not required to have high accuracy, and the formation of the terminal insertion hole 31 becomes easier.
　また、ＩＥＣ（国際電気標準会議）では、アース接地の信頼性向上のため、アース端子部２４に取り付け板（構造物）３への保持構造が要求される。そこで、本実施形態のアース端子部２４は、中央片２４１の一面から切り起された切り起し片２４４を有している。図１で定義した方向で説明すれば、アース端子部２４を端子挿通孔３１に挿通させる際、切り起し片２４４は、右面が端子挿通孔３１の内周縁に当接しながら左方へ撓むことで、端子挿通孔３１に挿通する。そして、端子挿通孔３１を挿通した後は、切り起し片２４４の先端部２４４ｂが端子挿通孔３１よりも右側に変位しているため、取り付け板３への抜け止めがなされ、取り付け板３に保持される。つまり、アース端子部２４は、第１端２４１ａから第２端２４１ｂに向けて突出する突出片２４４を備える。突出片２４４は、第１端２４１ａ側の基端部２４４ａで中央片２４１に固定され、先端部２４４ｂが中央片２４１から離れる方向（図３の紙面垂直方向）に突出している。つまり、突出片２４４は先端部２４４ｂが中央片２４１の厚み方向（図１０の上下方向）に撓むように、基端部２４４ａで中央片２４１に固定され、かつ、先端部２４４ｂが中央片２４１と離れて位置するように構成されている。 Further, in the IEC (International Electrotechnical Commission), in order to improve the reliability of the earthing, a structure for holding the mounting plate (structure) 3 on the earth terminal portion 24 is required. Therefore, the ground terminal portion 24 of the present embodiment has a cut-and-raised piece 244 cut and raised from one surface of the central piece 241. In the direction defined in FIG. 1, when the ground terminal portion 24 is inserted into the terminal insertion hole 31, the cut-and-raised piece 244 bends to the left while the right surface abuts on the inner peripheral edge of the terminal insertion hole 31. Thus, the terminal insertion hole 31 is inserted. Then, after the terminal insertion hole 31 is inserted, the tip portion 244 b of the cut-and-raised piece 244 is displaced to the right side of the terminal insertion hole 31, so that the detachment to the mounting plate 3 is prevented. It is held. That is, the ground terminal portion 24 includes the protruding piece 244 that protrudes from the first end 241 a toward the second end 241 b. The projecting piece 244 is fixed to the central piece 241 at the proximal end 244a on the first end 241a side, and the distal end 244b protrudes in the direction away from the central piece 241 (vertical direction in FIG. 3). That is, the projecting piece 244 is fixed to the central piece 241 at the proximal end 244a so that the distal end 244b bends in the thickness direction of the central piece 241 (vertical direction in FIG. 10), and the distal end 244b is separated from the central piece 241 Are configured to be positioned.
　また、突出片２４４は、傾斜部２４５よりも第１端２４１ａ側に形成される。つまり、アース端子部２４において、突出片２４４の基端部２４４ａ及び先端部２４４ｂは、傾斜部２４５よりも第１端２４１ａ側にある。本実施形態では、突出片２４４の幅（図３における左右方向の長さ）は、アース端子部２４の第１端２４１ａ側における幅Ｌ１より小さく形成されている。 In addition, the protruding piece 244 is formed closer to the first end 241 a than the inclined portion 245. That is, in the ground terminal portion 24, the proximal end 244 a and the distal end 244 b of the protruding piece 244 are closer to the first end 241 a than the inclined portion 245. In the present embodiment, the width (length in the horizontal direction in FIG. 3) of the protruding piece 244 is formed smaller than the width L1 on the first end 241 a side of the ground terminal portion 24.
　また、突出片２４４の先端部２４４ｂと中央片２４１との中央片２４１の厚み方向の距離Ｌ６は、端子挿通孔３１の厚みＬ５より大きくともよい。Ｌ６がＬ５より大きい場合であっても、アース端子部２４を端子挿通孔３１に第１端２４１ａ側から挿入すれば、突出片２４４の先端部２４４ｂは中央片２４１の厚み方向に撓んで、突出片２４４を端子挿通孔３１に通過させることができる。そして、側片２４２が端子挿通孔３１の内周面に接することができる。 Further, the distance L6 in the thickness direction of the central piece 241 between the tip portion 244b of the protruding piece 244 and the central piece 241 may be larger than the thickness L5 of the terminal insertion hole 31. Even when L6 is larger than L5, if the ground terminal portion 24 is inserted into the terminal insertion hole 31 from the first end 241a side, the tip portion 244b of the protruding piece 244 is bent in the thickness direction of the central piece 241 and protrudes The piece 244 can be passed through the terminal insertion hole 31. Then, the side piece 242 can be in contact with the inner peripheral surface of the terminal insertion hole 31.
　また、本実施形態の導電ブロック２は、一つの板材を折り曲げ加工することで各部を形成しているため、組み立て時の部品点数を減らすことができ、組み立て費を削減することができる。つまり、アース端子部２４は、接続端子部２００に一体に形成される。 Moreover, since each part is formed by bending-processing one board | plate material, the electrically conductive block 2 of this embodiment can reduce the number of parts at the time of an assembly, and can reduce an assembly cost. That is, the ground terminal portion 24 is integrally formed with the connection terminal portion 200.
