Description

この発明は、例えば誘導灯照明器具または非常灯照明器具に内蔵する電子回路に電源を接続するための電源端子台などの端子台に関するものである。   The present invention relates to a terminal block such as a power supply terminal block for connecting a power source to an electronic circuit built in, for example, a guide light lighting device or an emergency light lighting device.

従来のアース端子を有する端子台として、取付面に突出したアース端子とアース端子の両側に位置決め突起を設け、かつ、アース端子の近傍に１点のねじ止め用取付穴を設けたものがあった（例えば特許文献１参照）。   As a conventional terminal block having a grounding terminal, there is a grounding terminal protruding on the mounting surface, positioning protrusions on both sides of the grounding terminal, and one mounting screw mounting hole in the vicinity of the grounding terminal. (For example, refer to Patent Document 1).

また別の端子台として、２点の取付部とそれらを結ぶ線上から外れた位置にアース端子を突出したものもあった。
特開平５−３０７９７９号公報 As another terminal block, there is one in which a grounding terminal protrudes from a position where two attachment portions and a line connecting them are removed.
Japanese Patent Laid-Open No. 5-307979

これらのアース端子は取付板のアース接触部となる、板厚や加工公差に配慮したアース用穴に対応しなければならないが、従来例のうち前者では位置決め突起があるものの１点止めであるため、後者では２点止めであるが取付部とアース端子の間に距離があるため、いずれもアース端子に十分な圧力を掛けられない。このため、アース端子自体にばね性をもたせるとともにアース用穴の公差に対応するため先端を尖らせ、端子台からの突出長さが長い端子構造をとることが多かった。   These ground terminals must correspond to the grounding holes that take into account the plate thickness and processing tolerances, which are the ground contact parts of the mounting plate, but the former example has a positioning projection in the former, but it is a single point stop. In the latter case, two points are used, but since there is a distance between the mounting portion and the ground terminal, neither of them can apply sufficient pressure to the ground terminal. For this reason, in many cases, the ground terminal itself has a spring structure and has a long terminal structure with a sharp tip and a long protrusion from the terminal block in order to cope with the tolerance of the ground hole.

しかしながら、誘導灯照明器具においてはデザイン面から器具を薄く作る必要があるため、アース端子の出代を短くすることが必要であった。   However, since it is necessary to make the appliance thin in terms of design in the guide lamp lighting fixture, it is necessary to shorten the allowance of the ground terminal.

したがって、この発明の目的は、アース端子を長くすることなく確実に被取付体に接触することができる端子台を提供することである。   Therefore, an object of the present invention is to provide a terminal block that can reliably contact the mounted body without lengthening the ground terminal.

この発明の端子台は、アース接触部を有する被取付体に取付けられるものである。ハウジングは前記被取付体に取付ける取付面を有し前記取付面にアース用スリットを有する。端子装置はハウジングに収納されて電線接続端子部とアース端子部を有する。前記アース端子部は前記アース用スリットから外方に突出して前記アース接触部に接触するアース端子と、前記アース端子を突出方向に付勢するばね部を有する。前記電線接続端子部は前記ばね部の弾性変形による前記アース端子の後退位置を規制するストッパ部を有する。   The terminal block of this invention is attached to a to-be-attached body which has a ground contact part. The housing has a mounting surface for mounting on the mounted body, and has a grounding slit on the mounting surface. The terminal device is housed in a housing and has a wire connection terminal portion and a ground terminal portion. The ground terminal part has an earth terminal protruding outward from the earth slit and contacting the earth contact part, and a spring part for biasing the earth terminal in the projecting direction. The electric wire connection terminal portion has a stopper portion that regulates the retracted position of the ground terminal due to elastic deformation of the spring portion.

上記構成において、前記電線接続端子部は速結端子であり、前記端子装置は前記速結端子と前記アース端子部とをつなぐ細長の導電板を有し、前記ばね部は前記導電板の長手方向に形成された切り筋により前記導電板の一側縁と前記切り筋との間に形成した両持ち支持梁であり、前記アース端子は前記導電板の前記一側縁より板厚方向に折曲したものである。   In the above configuration, the wire connection terminal portion is a quick connection terminal, the terminal device has an elongated conductive plate that connects the quick connection terminal and the ground terminal portion, and the spring portion is a longitudinal direction of the conductive plate. A doubly-supported support beam formed between one side edge of the conductive plate and the cut line by a cut line formed on the conductive plate, and the ground terminal is bent in the plate thickness direction from the one side edge of the conductive plate. It is a thing.

上記構成において、前記電線接続端子部は速結端子であり、前記端子装置は前記速結端子と前記アース端子部とをつなぐ細長の導電板を有し、前記ばね部は前記導電板の一側縁から前記導電板の長手方向に延びた切り筋により前記導電板の一側縁と前記切り筋との間に形成された片持ち支持梁であり、前記アース端子は前記導電板の前記一側縁より板厚方向に折曲したものである。   In the above configuration, the wire connection terminal portion is a quick connection terminal, the terminal device has an elongated conductive plate that connects the quick connection terminal and the ground terminal portion, and the spring portion is on one side of the conductive plate. A cantilever supporting beam formed between one side edge of the conductive plate and the cut line by a cut line extending from the edge in the longitudinal direction of the conductive plate, and the ground terminal is the one side of the conductive plate It is bent in the thickness direction from the edge.

上記構成において、前記速結端子と前記アース端子は前記切り筋を間にして前記導電板の両側に連接されている。   The said structure WHEREIN: The said quick connection terminal and the said earthing terminal are connected with the both sides of the said electrically-conductive board through the said cut line.

上記構成において、前記被取付体の前記アース端子が接触する部分は前記アース端子が穴縁に接触するように嵌合するアース用穴であり、前記アース端子の板幅方向と異なる方向の前記アース用穴の縁部にスリットを有する。   In the above configuration, the portion of the mounted body that is in contact with the ground terminal is a ground hole that fits so that the ground terminal contacts the edge of the hole, and the ground in a direction different from the plate width direction of the ground terminal. A slit is provided at the edge of the hole.

この発明の端子台によれば、アース端子を突出方向に付勢するばね部を有するため、ばね部を例えば電源端子台の取付方向と直交する方向に設けることができるので、アース端子の特に電源端子台からの突出長さを短くすることができる。またストッパ部によりばね部の過変形を防止することができる。   According to the terminal block of the present invention, since the ground portion has the spring portion that urges the ground terminal in the protruding direction, the spring portion can be provided in a direction orthogonal to the mounting direction of the power terminal block, for example. The projecting length from the terminal block can be shortened. Further, the spring portion can be prevented from being excessively deformed by the stopper portion.

ばね部を切り筋により形成された両持ち梁とすることにより、切り筋の長さを変えることで容易にばね定数を変えることが可能となる。   The spring constant can be easily changed by changing the length of the cut line by making the spring portion a doubly-supported beam formed by the cut line.

切り筋を間にして速結端子とアース端子を設けることにより、材料歩留りを向上することができる。   The material yield can be improved by providing the quick connection terminal and the ground terminal with the cut line in between.

スリットにより、アース用穴の縁部に弾性を付与することができるので、アース接続の信頼性をさらに向上することができる。   Since the slit can provide elasticity to the edge of the ground hole, the reliability of the ground connection can be further improved.

この発明の第１の実施の形態の電源端子台を図１から図１２により説明する。すなわち、この電源端子台はハウジング１内に速結端子２などの電線接続端子やアース端子３８を設けた端子装置を収納している。   A power supply terminal block according to a first embodiment of the present invention will be described with reference to FIGS. That is, this power supply terminal block houses a terminal device in which a wire connection terminal such as the quick connection terminal 2 and a ground terminal 38 are provided in the housing 1.

ハウジング１は樹脂製のボディ３と樹脂製のカバー４からなる。ボディ３は底浅の箱形であり、周囲は前端壁５、後端壁６および両側壁７、８からなっており、底部の外面が取付面３ａとなっている。後端壁６および両側壁７、８は同じ高さであるが、前端壁５はそれらよりも高くかつ他の壁と同じ高さに外方に張り出す段部９を形成し、段部９の先端からさらに支持壁１０を立設している。ボディ３内には前端壁５と後端壁６との間をつなぐように複数条例えば４条の隔壁１１を設けて隔壁１１および側壁７、８との間に形成される溝のうち中央の溝を除く４条を端子収納溝１２としている。これらの端子収納溝１２内に位置するように支持壁１０に端子支持用のスリット１３を形成している。また一側壁８の前端壁５寄りに前端壁５の幅を狭くする凹部１４を形成している。さらに両側壁７、８にそれぞれカバー固定部としてカバー取付け爪１５を突設している。   The housing 1 includes a resin body 3 and a resin cover 4. The body 3 has a shallow bottom box shape, and its periphery is composed of a front end wall 5, a rear end wall 6, and both side walls 7 and 8, and an outer surface of the bottom portion is a mounting surface 3a. The rear end wall 6 and the side walls 7 and 8 have the same height, but the front end wall 5 forms a step 9 that protrudes outwardly to the same height as the other walls. Further, a support wall 10 is erected from the tip of each of them. In the body 3, a plurality of strips 11, for example, four strips 11 are provided so as to connect the front end wall 5 and the rear end wall 6, and the center of the grooves formed between the partition walls 11 and the side walls 7, 8 is provided. The four strips excluding the grooves serve as terminal storage grooves 12. Terminal support slits 13 are formed in the support wall 10 so as to be positioned in these terminal storage grooves 12. Further, a recess 14 that narrows the width of the front end wall 5 is formed near the front end wall 5 of the one side wall 8. Further, cover mounting claws 15 are provided projecting from both side walls 7 and 8 as cover fixing portions.

カバー４はボディ３に冠合する相似形状をなしており、前端壁５の前面には被さらないで前方に張り出す端子押さえ片１６を設けている。カバー４の両側壁にカバー取付け爪１５を嵌合させる連結孔４６を形成するとともに取付部１７をカバー４の開口端よりも上方に位置して外方に張り出している。１８はねじ挿通穴である。１９は凸部であり、ねじ挿通穴１８の径とこれに挿通するねじの径との差による電源端子台の取付部１７での位置ずれを防止する位置決めに用いる。これは電線を速結端子２に差し込んだり抜き出す場合に加わる外力によって電源端子台が動くのを確実に防止し、後述の刃形端子３６の差し込み時のおよび差し込み状態でのねじれ等の変形を防止することを目的としている。   The cover 4 has a similar shape that meshes with the body 3, and is provided with a terminal pressing piece 16 that projects forward without covering the front surface of the front end wall 5. A connecting hole 46 for fitting the cover mounting claws 15 is formed on both side walls of the cover 4, and the mounting portion 17 is located above the opening end of the cover 4 and projects outward. Reference numeral 18 denotes a screw insertion hole. Reference numeral 19 denotes a convex portion, which is used for positioning to prevent displacement of the power terminal block attachment portion 17 due to the difference between the diameter of the screw insertion hole 18 and the diameter of the screw inserted therethrough. This reliably prevents the power supply terminal block from being moved by an external force applied when the electric wire is inserted into or extracted from the quick connection terminal 2, and prevents deformation such as twisting when the blade-shaped terminal 36, which will be described later, is inserted. The purpose is to do.

カバー４の上面は前端から後端にかけて波形に形成している。波形の山は２つであり、各山の傾斜面２０〜２３のうち端子押さえ片１６に向いた傾斜面２０、２２にそれぞれ電線挿入穴２４ａ〜２４ｄ、２５ａ〜２５ｄを形成している。これらの電線挿入穴２４ａ〜２４ｄ、２５ａ〜２５ｄはボディ３の４個の端子収納溝１２に対向するように形成されている。この場合、電線挿入穴２４ｃ、２４ｄの間および電線挿入穴２５ｃ、２５ｄの間に識別用突起２６を設けている。識別用突起２６は端に位置する電線挿入穴２４ｄ、２５ｄがアース端子用であることを示し、電源端子用の電線挿入穴２４ａ〜２４ｃおよび２５ａ〜２５ｃとの識別を容易にしている。カバー４の他の傾斜面２１、２３はボディ３の相隣接する端子収納溝１２にまたがるように電線解除部２８が一体形成されている。各電線解除部２８は相隣接する端子収納溝１２に収納される速結端子２の電線を同時に解除するようにしている。   The upper surface of the cover 4 is formed in a waveform from the front end to the rear end. There are two corrugated peaks, and electric wire insertion holes 24a to 24d and 25a to 25d are formed on the inclined surfaces 20 and 22 of the inclined surfaces 20 to 23 facing the terminal pressing piece 16 respectively. These wire insertion holes 24 a to 24 d and 25 a to 25 d are formed so as to face the four terminal storage grooves 12 of the body 3. In this case, identification protrusions 26 are provided between the wire insertion holes 24c and 24d and between the wire insertion holes 25c and 25d. The identification protrusion 26 indicates that the wire insertion holes 24d and 25d located at the ends are for ground terminals, and facilitates identification from the power supply terminal wire insertion holes 24a to 24c and 25a to 25c. The other inclined surfaces 21 and 23 of the cover 4 are integrally formed with a wire release portion 28 so as to straddle the adjacent terminal storage grooves 12 of the body 3. Each electric wire release part 28 is made to release simultaneously the electric wire of the quick connection terminal 2 accommodated in the terminal storage groove 12 adjacent to each other.

端子装置は各端子収納溝１２に収納される。端子装置の速結端子２は、各端子収納溝１２に収納される細長の導電板３０に形成されている。ボディ３の両側の端子収納溝１２に収納される導電板３０はそれぞれ互いに反対側で側壁７、８に近い側部にカバー４の各波形の山に対応して２個の端子部３１を立ち上げている。端子部３１には鎖錠片３２、電線接続部３３および電線接触部３４が形成されている。鎖錠片３２と電線接続部３３の間の電線挿入部分は電線挿入穴２４ａ、２４ｄ、２５ａ、２５ｄに対向するように傾斜しており、カバー４の電線解除部２８のある傾斜面２１、２３の内側に位置している。したがって、電線挿入穴２４ａ、２４ｄ、２５ａ、２５ｄより電線を挿入すると電線の先端が鎖錠片３２と電線接続部３３との間に挿入され、電線接触部３４に接触した状態で結線状態となる。またその状態で電線解除部２８を押すと鎖錠片３２が押圧されて鎖錠片３２の電線への食い込みが解除され、電線を引き抜くことができる。７６は鎖錠片３２の過変形防止片であり、端子部３１に切り起こされている。   The terminal device is stored in each terminal storage groove 12. The quick connection terminal 2 of the terminal device is formed on an elongated conductive plate 30 accommodated in each terminal accommodating groove 12. The conductive plates 30 housed in the terminal housing grooves 12 on both sides of the body 3 are respectively provided with two terminal portions 31 corresponding to the corrugated peaks of the cover 4 on the sides opposite to the side walls 7 and 8 on opposite sides. Raised. The terminal portion 31 is formed with a locking piece 32, an electric wire connection portion 33 and an electric wire contact portion 34. The wire insertion portion between the locking piece 32 and the wire connection portion 33 is inclined so as to oppose the wire insertion holes 24 a, 24 d, 25 a, 25 d, and the inclined surfaces 21, 23 with the wire release portions 28 of the cover 4. Located inside. Therefore, when an electric wire is inserted from the electric wire insertion holes 24a, 24d, 25a, and 25d, the tip of the electric wire is inserted between the locking piece 32 and the electric wire connecting portion 33, and a connected state is brought into contact with the electric wire contact portion 34. . Further, when the electric wire release portion 28 is pushed in this state, the locking piece 32 is pressed, the biting of the locking piece 32 into the electric wire is released, and the electric wire can be pulled out. Reference numeral 76 denotes an over-deformation preventing piece of the locking piece 32, which is cut and raised at the terminal portion 31.

また、導電板１２のボディ３の前端壁５側に収納される一端部の側部より刃形端子３６が立ち上がるように折り曲げられている。刃形端子３６は導電板３０の前端より逆Ｌ字形に前方に延出している。導電板３０を端子収納溝１２に収納した状態で刃形端子３６は支持壁１０のスリット１３に挿通され、これに位置決めされ変形防止されている。また刃形端子３６の先端部には縦長のリブ３７を形成し、リブ３７の下端は刃形端子３６の下端すなわち差し込み端よりも若干上側すなわち後端寄りに位置し、上端は刃形端子３６の上端（後端）まで延びている。   Further, the blade terminal 36 is bent so as to rise from a side portion of one end portion housed on the front end wall 5 side of the body 3 of the conductive plate 12. The blade terminal 36 extends forward in an inverted L shape from the front end of the conductive plate 30. The blade terminal 36 is inserted into the slit 13 of the support wall 10 in a state where the conductive plate 30 is stored in the terminal storage groove 12, and is positioned and prevented from being deformed. Further, a longitudinally long rib 37 is formed at the tip of the blade-shaped terminal 36, and the lower end of the rib 37 is located slightly above the lower end of the blade-shaped terminal 36, that is, the insertion end, that is, closer to the rear end. It extends to the upper end (rear end).

速結端子２と刃形端子３６は導電板３０の同じ側部より立ち上げており、４つ並んだ導電板３０のうちの１つおきの導電板３０は、導電板３０の同じ側部より端子部３１および刃形端子３６を立ち上げ、隣合う導電板３０の端子部３１および刃形端子３６は導電板３０の反対側の側部より立ち上げて対称な形状となっている。速結端子２のうち凹部１４に隣接する端子収納溝１２に収納されたものはアース用であり、他は電源用または送り用である。   The quick connection terminal 2 and the blade-shaped terminal 36 are raised from the same side portion of the conductive plate 30, and every other conductive plate 30 of the four conductive plates 30 arranged from the same side portion of the conductive plate 30. The terminal portion 31 and the blade-shaped terminal 36 are raised, and the terminal portion 31 and the blade-shaped terminal 36 of the adjacent conductive plate 30 are raised from the opposite side portion of the conductive plate 30 to have a symmetrical shape. Of the quick connection terminals 2, those stored in the terminal storage grooves 12 adjacent to the recesses 14 are for grounding, and others are for power supply or for feeding.

さらに速結端子２のうちのアース用端子はアース端子部７０を設けている。アース端子部７０はばね部７１とアース端子３８からなる。ばね部７１は刃形端子３６寄りの速結端子２の立ち上がり位置に、導電板３０の長手方向に切り筋７２を付け、切り筋７２と速結端子２の立ち上がり側と反対側の導電板３０の側部との間の両持ち支持梁により形成している。アース端子３８は両持ち支持梁に形成されるが、切り筋７２を間にして速結端子２の立ち上がり側と反対側の側部より速結端子２の端子部３１と反対向きに折曲している。これにより、アース端子３８が導電板３０の板厚方向に弾性を有することとなるが、ばね部７１を挟んでアース端子３８と反対側に速結端子２が配置され、この速結端子２のばね部７１上にストッパ部７４を設けアース端子３８の後退動作を規制し、ばね部７１の過変形を防止している。またアース端子３８を刃形端子３６の基部側で切り筋７２を間にして導電板３０の両側に速結端子２とアース端子３８を折曲することにより材料歩留りが悪くならない。   Further, the ground terminal of the quick connection terminal 2 is provided with a ground terminal portion 70. The ground terminal portion 70 includes a spring portion 71 and a ground terminal 38. The spring portion 71 has a cut line 72 in the longitudinal direction of the conductive plate 30 at the rising position of the quick connection terminal 2 near the blade terminal 36, and the conductive plate 30 on the opposite side of the rising line of the cut line 72 and the quick connection terminal 2. It is formed by a doubly supported beam between the sides. The ground terminal 38 is formed as a both-end support beam, but is bent in the direction opposite to the terminal portion 31 of the quick connection terminal 2 from the side opposite to the rising side of the quick connection terminal 2 with the cut line 72 in between. ing. As a result, the ground terminal 38 has elasticity in the plate thickness direction of the conductive plate 30, but the quick connection terminal 2 is disposed on the opposite side of the ground terminal 38 with the spring portion 71 interposed therebetween. A stopper portion 74 is provided on the spring portion 71 to restrict the backward movement of the ground terminal 38 and prevent the spring portion 71 from being excessively deformed. Further, the material yield is not deteriorated by bending the quick connection terminal 2 and the ground terminal 38 on both sides of the conductive plate 30 with the ground terminal 38 on the base side of the blade-shaped terminal 36 with the cut line 72 in between.

アース端子３８はボディ７の底部に形成したスリット３９より取付面３ａの外部に突出し、ボディ７を被取付体となる例えば器体の金属製の取付板５５に取付ける際に、取付板５５に形成したアース接触部となるアース穴用６０に挿入され圧接接続される。このとき、取付操作によりアース端子３８の先端が取付板５５のアース用穴６０に嵌合するとともに取付方向とは反対の方向の反力を受け、ばね部７１はこの反力により弾性変形可能な変形代を有する。アース用穴６０はアース端子３８の板幅方向と異なる方向例えば板厚方向の縁部にスリット７５を形成し、穴縁に弾性を付与している。   The ground terminal 38 protrudes to the outside of the mounting surface 3a from a slit 39 formed at the bottom of the body 7, and is formed on the mounting plate 55 when the body 7 is mounted on a metal mounting plate 55, for example, a container body. It is inserted into the ground hole 60 to be the ground contact portion and is press-connected. At this time, the tip of the ground terminal 38 is fitted in the grounding hole 60 of the mounting plate 55 by the mounting operation and receives a reaction force in the direction opposite to the mounting direction, and the spring portion 71 can be elastically deformed by this reaction force. Has deformation allowance. The grounding hole 60 is formed with a slit 75 in an edge portion in a direction different from the plate width direction of the ground terminal 38, for example, in the plate thickness direction, and gives elasticity to the hole edge.

この電源端子台の組立は、ボディ３内に速結端子２を収納し刃形端子３６をスリット１３に通し、アース端子３８をスリット３９に通してカバー４をボディ３に閉じることにより行われる。このときカバー４の端子押さえ片１６の下面は刃形端子３６の上端に当接している。   The power terminal block is assembled by housing the quick connection terminal 2 in the body 3, passing the blade-shaped terminal 36 through the slit 13, passing the ground terminal 38 through the slit 39, and closing the cover 4 to the body 3. At this time, the lower surface of the terminal pressing piece 16 of the cover 4 is in contact with the upper end of the blade-shaped terminal 36.

電源端子台は取付板５５に設けたプリント基板のコネクタ４０に接続するように取付板５５に取付けられる。ここで、取付板５５には取付板５の表面に取付面３ａが当接する状態で取付部１７を受けるねじ孔のある取付受け部（図示せず）を突設するとともに、位置決め部５０の穴に嵌合する位置決め受け部（図示せず）を形成している。コネクタ４０の受け部（受け刃）４１に刃形端子３６を差し込む前に位置決め受け部に位置決め部５０が嵌合開始し、電源端子台を取付板５５に位置決めする。このように位置決めされながら、刃形端子３６をコネクタ４０の受け部４１に差し込みボディ３の取付面３ａを取付板５５に置く。刃形端子３６の圧接接続後に取付部１７のねじ挿通孔１８を通して取付板５５の台状の取付受け部のねじ孔にねじを締めつけて固定する。このとき、カバー４の端子押さえ片１６を押すことで確実に刃形端子３６を受け部４１に差し込むことができる。   The power terminal block is attached to the attachment plate 55 so as to be connected to the connector 40 of the printed circuit board provided on the attachment plate 55. Here, the mounting plate 55 is provided with a mounting receiving portion (not shown) having a screw hole for receiving the mounting portion 17 in a state where the mounting surface 3 a is in contact with the surface of the mounting plate 5, and a hole in the positioning portion 50. A positioning receiving portion (not shown) is formed to be fitted to the. Before the blade-shaped terminal 36 is inserted into the receiving portion (receiving blade) 41 of the connector 40, the positioning portion 50 starts to be fitted into the positioning receiving portion, and the power terminal block is positioned on the mounting plate 55.
