Description

この発明は、電線や通信線などに取り付けられた端子を、ネジを介して接続する端子台に関する。 The present invention relates to a terminal block for connecting a terminal attached to an electric wire, a communication line or the like via a screw.

電線などに取り付けられた圧着端子を端子台に接続する場合、端子台の端子板にネジ孔が形成され、端子には、接続ネジを挿入するための丸孔やスリットなどの挿入孔が形成されている。そして、端子の挿入孔を端子板のネジ孔に合わせた状態で、接続ネジをネジ孔に締め付けることで、端子板と接続ネジとで端子を挟持するものである。また、接続ネジの脱落・離脱を防止するために、ネジ孔の軸方向に対して接続ネジが移動自在に保持されている端子台が知られている（例えば、特許文献１参照。）。 When connecting a crimp terminal attached to an electric wire or the like to a terminal block, screw holes are formed in the terminal block of the terminal block, and insertion holes such as round holes and slits for inserting connection screws are formed in the terminal. ing. Then, the terminal is clamped between the terminal plate and the connection screw by tightening the connection screw in the screw hole in a state where the insertion hole of the terminal is aligned with the screw hole of the terminal plate. Also, a terminal block is known in which a connection screw is movably held with respect to the axial direction of the screw hole in order to prevent the connection screw from falling off or coming off (see, for example, Patent Document 1).

特開２００９−１４０６６５号公報JP 2009-140665 A

ところで、上記のような端子台では、端子の挿入孔が端子板のネジ孔に合っていない状態でも、接続ネジをネジ孔に締め付けることができる。このため例えば、図８に示すように、端子１００の挿入孔１００ａに接続ネジ１０１を挿入しないで、端子１００の先端のみを挟んだ状態で、接続ネジ１０１を端子板１０２のネジ孔１０２ａに締め付けてしまう場合があり得る。特に、多数の端子板１０２、ネジ孔１０２ａが密接して配設され、多くの端子１００を接続する場合には、このような不適正な接続が生じるおそれがある。そして、端子１００の接続が不適正であると、電線１０３などに外力が加わった場合に、端子１００が端子板１０２から外れたり、接触不良が生じたりするおそれがある。また、上記特許文献１の端子台は、接続ネジの脱落を防止することはできるが、端子の不適正な接続を防止することはできない。 By the way, in the terminal block as described above, the connection screw can be fastened to the screw hole even in a state where the insertion hole of the terminal does not match the screw hole of the terminal plate. Therefore, for example, as shown in FIG. 8, the connection screw 101 is not inserted into the insertion hole 100 a of the terminal 100, and the connection screw 101 is tightened into the screw hole 102 a of the terminal plate 102 with only the tip of the terminal 100 being sandwiched. It can happen. In particular, when a large number of terminal plates 102 and screw holes 102a are arranged in close contact with each other and many terminals 100 are connected, such an improper connection may occur. If the connection of the terminal 100 is inappropriate, when an external force is applied to the electric wire 103 or the like, the terminal 100 may be detached from the terminal plate 102 or a contact failure may occur. Moreover, although the terminal block of the said patent document 1 can prevent omission of a connection screw, it cannot prevent improper connection of a terminal.

そこでこの発明は、端子の不適正な接続を防止することが可能な端子台を提供することを目的とする。 Therefore, an object of the present invention is to provide a terminal block that can prevent an inappropriate connection of terminals.

上記課題を解決するために、請求項１に記載の発明は、端子板にネジ孔が形成され、前記ネジ孔に接続ネジが螺合されて前記端子板と接続ネジとで端子を挟持する端子台であり、外力が加わらない状態では前記ネジ孔の少なくとも一部を覆い、前記端子を押し込むと移動または変形する障害体を備え、前記端子を所定の位置まで押し込み可能なように、前記障害体が配設されている、ことを特徴とする。 In order to solve the above-mentioned problem, the invention according to claim 1 is a terminal in which a screw hole is formed in a terminal plate, a connection screw is screwed into the screw hole, and a terminal is sandwiched between the terminal plate and the connection screw. The obstacle includes a obstacle that covers at least a part of the screw hole in a state where no external force is applied, and moves or deforms when the terminal is pushed, so that the terminal can be pushed to a predetermined position. Is provided.

この発明によれば、端子を押し込まない状態では、障害体によってネジ孔が覆われているため、ネジ孔に接続ネジを螺合することができない。また、端子を押し込むことで、障害体が移動または変形し、端子を所定の位置まで押し込んだ状態でネジ孔に接続ネジを螺合することで、端子が端子板と接続ネジとで挟持される。 According to this invention, when the terminal is not pushed in, the screw hole is covered with the obstacle, and therefore the connection screw cannot be screwed into the screw hole. Also, when the terminal is pushed in, the obstacle moves or deforms, and the terminal is clamped between the terminal plate and the connecting screw by screwing the connecting screw into the screw hole with the terminal pushed to a predetermined position. .

請求項２に記載の発明は、請求項１に記載の端子台において、前記障害体は、前記端子板にスライド自在に配設され、前記端子を押し込むとスライドして移動する、ことを特徴とする。 The invention according to claim 2 is characterized in that, in the terminal block according to claim 1, the obstacle is slidably disposed on the terminal plate, and slides and moves when the terminal is pushed in. To do.

請求項３に記載の発明は、請求項１に記載の端子台において、前記障害体は、板バネから構成され、前記端子を押し込むと変形する、ことを特徴とする。 According to a third aspect of the present invention, in the terminal block according to the first aspect, the obstacle is formed of a leaf spring, and is deformed when the terminal is pushed in.

請求項１に記載の発明によれば、端子を押し込まない状態では、障害体によってネジ孔が覆われているため、例えば、端子が障害体つまりネジ孔に達していない状態で、接続ネジをネジ孔に螺合させる（端子の先端のみを挟んで接続する）、という不適正な接続が生じることがない。また、端子を押し込んで、障害体を移動または変形させても、端子の挿入孔とネジ孔とが一致しない状態では、端子の挿入孔の周縁が障害・邪魔になって接続ネジをネジ孔に螺合させることができない。つまり、端子を所定の位置まで押し込んで、端子の挿入孔とネジ孔とを一致させなければ、接続ネジをネジ孔に螺合させることができない。このようにして、端子の不適正な接続を防止することが可能となる。 According to the first aspect of the present invention, since the screw hole is covered with the obstacle when the terminal is not pushed in, the connecting screw is screwed in the state where the terminal does not reach the obstacle, that is, the screw hole. Inappropriate connection of screwing into the hole (connecting only the tip of the terminal) is not caused. If the terminal insertion hole and the screw hole do not match even if the obstacle is moved or deformed by pushing the terminal, the peripheral edge of the terminal insertion hole becomes an obstacle or obstruction, and the connection screw becomes a screw hole. It cannot be screwed. That is, the connection screw cannot be screwed into the screw hole unless the terminal is pushed to a predetermined position so that the insertion hole of the terminal matches the screw hole. In this way, inappropriate connection of terminals can be prevented.

請求項２に記載の発明によれば、障害体がスライド自在となっているため、端子の押し込みが円滑となり、端子の接続作業を容易に行うことが可能となる。 According to the second aspect of the present invention, since the obstacle is slidable, the terminal can be pushed in smoothly, and the terminal can be easily connected.

請求項３に記載の発明によれば、障害体が板バネから構成されているため、構成が簡易で、容易かつ低コストで製作することが可能となる。 According to the third aspect of the present invention, since the obstacle is composed of a leaf spring, the structure is simple, and it can be manufactured easily and at low cost.

以下、この発明を図示の実施の形態に基づいて説明する。 The present invention will be described below based on the illustrated embodiments.

（実施の形態１）
図１は、この実施の形態に係る端子台１を示す斜視図である。この端子台１は、電線や通信線などに取り付けられた端子を、ネジを介して接続する接続台であり、この実施の形態では、制御ケーブル２００の先端に圧着端子（端子）２０１が取り付けられ、この圧着端子２０１に円形の挿入孔２０１ａが形成されている場合について説明する。 (Embodiment 1)
FIG. 1 is a perspective view showing a terminal block 1 according to this embodiment. The terminal block 1 is a connection base that connects terminals attached to electric wires, communication lines, and the like via screws. In this embodiment, a crimp terminal (terminal) 201 is attached to the tip of the control cable 200. The case where a circular insertion hole 201a is formed in the crimp terminal 201 will be described.

端子台１は、主として、端子板２と、スライド部材（障害体）３と、ガイド部材４とを備えている。 The terminal block 1 mainly includes a terminal plate 2, a slide member (obstacle) 3, and a guide member 4.

端子板２は、平板状で導電材から構成され、略中央部にネジ孔（雌ネジ）２ａが形成されている。そして、後述するようにして、ネジ孔２ａに圧着端子２０１の挿入孔２０１ａを一致させて、ネジ孔２ａに接続ネジ２０２（雄ネジ、図３）を螺合させることで、端子板２と接続ネジ２０２の頭部とで圧着端子２０１が挟持される。 The terminal plate 2 is a flat plate made of a conductive material, and has a screw hole (female screw) 2a formed at a substantially central portion. Then, as described later, the insertion hole 201a of the crimp terminal 201 is aligned with the screw hole 2a, and the connection screw 202 (male screw, FIG. 3) is screwed into the screw hole 2a, thereby connecting to the terminal plate 2. The crimp terminal 201 is sandwiched between the heads of the screws 202.

また、端子板２には、図１〜３に示すように、ネジ孔２ａと連通する長孔状のスライド孔２ｂが形成されている。このスライド孔２ｂは、圧着端子２０１の押し込み・差し込み方向（図２中矢印Ｘ方向）に延びる略長方形で、その幅（矢印Ｘと垂直な方向の長さ）は、後述するスライド部材３の垂直部３ａの幅Ｈ１よりもやや大きく設定されている。また、スライド孔２ｂの長さは、後述するようにしてスライド部材３がスライドし、圧着端子２０１の挿入孔２０１ａがネジ孔２ａに一致するように、設定されている。 Moreover, as shown in FIGS. 1-3, the terminal board 2 is formed with a long hole-like slide hole 2b communicating with the screw hole 2a. The slide hole 2b has a substantially rectangular shape extending in the direction in which the crimp terminal 201 is pushed in and inserted (in the direction of the arrow X in FIG. 2), and the width (length in the direction perpendicular to the arrow X) is vertical to the slide member 3 to be described later. It is set to be slightly larger than the width H1 of the portion 3a. Further, the length of the slide hole 2b is set so that the slide member 3 slides as described later, and the insertion hole 201a of the crimp terminal 201 coincides with the screw hole 2a.

スライド部材３は、端子板２の板面に沿ってスライド自在に端子板２に配設された部材であり、図４に示すように、垂直部３ａと基部３ｂとツバ部３ｃとを備えている。垂直部３ａは、図中垂直上方に延びる角棒状で、端子板２のスライド孔２ｂに、スライド自在に挿入・装着される。また、基部３ｂは、垂直部３ａの下部に突出するように形成された直方体で、ツバ部３ｃは、基部３ｂの両側面の反垂直部３ａ側に、両側面から突出するように形成されている。そして、基部３ｂが、後述するガイド部材４のガイド溝４ｂに挿入・装着され、ツバ部３ｃが、後述するガイド部材４の収容部４ａ側に位置するようになっている。 The slide member 3 is a member disposed on the terminal plate 2 so as to be slidable along the plate surface of the terminal plate 2, and includes a vertical portion 3a, a base portion 3b, and a flange portion 3c as shown in FIG. Yes. The vertical portion 3a has a rectangular bar shape extending vertically upward in the figure, and is slidably inserted into and mounted in the slide hole 2b of the terminal board 2. The base portion 3b is a rectangular parallelepiped formed so as to protrude from the lower portion of the vertical portion 3a, and the flange portion 3c is formed so as to protrude from both side surfaces on the anti-vertical portion 3a side of both side surfaces of the base portion 3b. Yes. The base portion 3b is inserted and mounted in a guide groove 4b of a guide member 4 to be described later, and the brim portion 3c is positioned on the accommodating portion 4a side of the guide member 4 to be described later.

ガイド部材４は、図５に示すように、略直方体で、上面から中央部にかけて四角形にくり抜いた収容部４ａが形成され、この収容部４ａから一方の端部に向かって切り抜かれたガイド溝４ｂが形成されている。収容部４ａの深さは、スライド部材３の基部３ｂの高さよりもやや大きく設定され、収容部４ａの長さ（図５中横方向の長さ）は、後述するようにしてスライド部材３がスライド可能で、かつ圧縮バネ５が収縮できるように設定されている。 As shown in FIG. 5, the guide member 4 is a substantially rectangular parallelepiped, and is formed with an accommodation portion 4a hollowed out in a square shape from the upper surface to the center portion, and the guide groove 4b cut out from the accommodation portion 4a toward one end portion. Is formed. The depth of the accommodating portion 4a is set to be slightly larger than the height of the base portion 3b of the slide member 3, and the length of the accommodating portion 4a (the length in the horizontal direction in FIG. 5) is determined by the slide member 3 as described later. It is set so that it can slide and the compression spring 5 can contract.

また、ガイド溝４ｂの幅Ｈ３は、スライド部材３の基部３ｂの幅Ｈ２よりもやや大きく設定され、収容部４ａとガイド溝４ｂとによる段差である肩部４ｃに、スライド部材３のツバ部３ｃが当接するようになっている。そして、スライド部材３の垂直部３ａが端子板２のスライド孔２ｂに装着され、基部３ｂがガイド部材４のガイド溝４ｂに装着され、ツバ部３ｃが収容部４ａ側に位置する状態で、スライド部材３のツバ部３ｃ側の端面と収容部４ａとの間に圧縮バネ５が収容されて、ガイド部材４が端子板２の下面に取り付けられている。 Further, the width H3 of the guide groove 4b is set to be slightly larger than the width H2 of the base portion 3b of the slide member 3, and the flange portion 3c of the slide member 3 is formed on the shoulder portion 4c which is a step between the housing portion 4a and the guide groove 4b. Are in contact with each other. The slide member 3 is slid in a state in which the vertical portion 3a is mounted in the slide hole 2b of the terminal plate 2, the base portion 3b is mounted in the guide groove 4b of the guide member 4, and the flange portion 3c is positioned on the accommodating portion 4a side. The compression spring 5 is accommodated between the end surface of the member 3 on the flange portion 3 c side and the accommodating portion 4 a, and the guide member 4 is attached to the lower surface of the terminal plate 2.

このような組み付け状態において、図２、３に示すように、端子板２の上面からの垂直部３ａの突出量が、圧着端子２０１の厚みよりも小さくなるように、垂直部３ａの長さが設定され、これにより、接続ネジ２０２などが垂直部３ａに当たらないようになっている。また、圧縮バネ５によってスライド部材３が常にネジ孔２ａ側に押圧され、外力が加わらない状態では、図２に示すように、垂直部３ａがネジ孔２ａの約半分を覆うようになっている。一方、図２中矢印Ｘ方向に圧着端子２０１を押し込むと、圧縮バネ５の力に抗してスライド部材３がＸ方向にスライドして移動・後退し、これに伴って、垂直部３ａがスライド孔２ｂに沿ってスライドする。 In such an assembled state, as shown in FIGS. 2 and 3, the length of the vertical portion 3 a is set so that the protruding amount of the vertical portion 3 a from the upper surface of the terminal plate 2 is smaller than the thickness of the crimp terminal 201. Thus, the connection screw 202 or the like is prevented from hitting the vertical portion 3a. In addition, when the slide member 3 is always pressed toward the screw hole 2a by the compression spring 5 and no external force is applied, the vertical portion 3a covers about half of the screw hole 2a as shown in FIG. . On the other hand, when the crimping terminal 201 is pushed in the direction of the arrow X in FIG. 2, the slide member 3 slides in the X direction against the force of the compression spring 5 and moves / retreats. Slide along the hole 2b.

このため、圧縮バネ５の力・バネ定数は、人手で圧着端子２０１を押し込むだけでスライド部材３が円滑にスライドするように、設定されている。また、圧着端子２０１を押し込み続けると、圧着端子２０１を所定の位置まで、つまり図３に示すように、圧着端子２０１の挿入孔２０１ａがネジ孔２ａに一致するまで、スライド部材３がスライドするように、圧縮バネ５の自然長、ガイド部材４の収容部４ａの長さなどが設定されている。そして、このようにしてスライド部材３がスライド・後退した状態では、ネジ孔２ａが完全に開放され、挿入孔２０１ａに接続ネジ２０２を挿入してネジ孔２ａに螺合可能となる。 For this reason, the force and spring constant of the compression spring 5 are set so that the slide member 3 slides smoothly only by pushing the crimp terminal 201 manually. If the crimp terminal 201 is continuously pushed in, the slide member 3 slides until the crimp terminal 201 reaches a predetermined position, that is, until the insertion hole 201a of the crimp terminal 201 matches the screw hole 2a as shown in FIG. Further, the natural length of the compression spring 5 and the length of the accommodating portion 4a of the guide member 4 are set. When the slide member 3 is slid and retracted in this manner, the screw hole 2a is completely opened, and the connection screw 202 can be inserted into the insertion hole 201a and can be screwed into the screw hole 2a.

このような端子板２やスライド部材３、ガイド部材４などが、多数並列に配設され、端子台１が構成されている。また、隣接する端子板２間には、側壁（図６、７参考）が設けられ、この実施の形態では上記のように、図２中矢印Ｘ方向からのみ圧着端子２０１を押し込め、Ｘ方向およびその反対方向にスライド部材３がスライド・往復動するようになっている。 A large number of such terminal plates 2, slide members 3, guide members 4, and the like are arranged in parallel to constitute a terminal block 1. Further, a side wall (see FIGS. 6 and 7) is provided between the adjacent terminal plates 2, and in this embodiment, as described above, the crimp terminal 201 is pushed only from the direction of the arrow X in FIG. The slide member 3 slides and reciprocates in the opposite direction.

次に、このような構成の端子台１への圧着端子２０１の接続方法などについて説明する。 Next, a method for connecting the crimp terminal 201 to the terminal block 1 having such a configuration will be described.

まず、圧着端子２０１をネジ孔２ａ側に押し込まない状態では、図２に示すように、スライド部材３の垂直部３ａがネジ孔２ａを覆っているため、ネジ孔２ａに接続ネジ２０２を螺合させることができない。次に、端子板２の上面に沿って圧着端子２０１をネジ孔２ａ側に押し込むと、スライド部材３がガイド部材４側にスライド、後退し、垂直部３ａがネジ孔２ａを覆わない状態となる。しかし、この時点では、圧着端子２０１の挿入孔２０１ａの周縁（先端部）が障害・邪魔になって、接続ネジ２０２をネジ孔２ａに螺合させることができない。 First, in a state where the crimp terminal 201 is not pushed into the screw hole 2a side, as shown in FIG. 2, the vertical portion 3a of the slide member 3 covers the screw hole 2a, so that the connection screw 202 is screwed into the screw hole 2a. I can't let you. Next, when the crimp terminal 201 is pushed into the screw hole 2a side along the upper surface of the terminal plate 2, the slide member 3 slides and retreats to the guide member 4 side, and the vertical portion 3a does not cover the screw hole 2a. . However, at this time, the peripheral edge (tip portion) of the insertion hole 201a of the crimp terminal 201 is obstructed and obstructed, and the connection screw 202 cannot be screwed into the screw hole 2a.

続いて、さらに圧着端子２０１をネジ孔２ａ側に押し込むと、図３に示すように、圧着端子２０１の挿入孔２０１ａがネジ孔２ａに一致し、この時点で、接続ネジ２０２を挿入孔２０１ａに挿入してネジ孔２ａに螺合する。そして、接続ネジ２０２を締め付けることで、接続ネジ２０２の頭部と端子板２とによって、圧着端子２０１が強固に挟持される。 Subsequently, when the crimp terminal 201 is further pushed into the screw hole 2a side, as shown in FIG. 3, the insertion hole 201a of the crimp terminal 201 matches the screw hole 2a. At this time, the connection screw 202 is inserted into the insertion hole 201a. Insert and screw into the screw hole 2a. Then, by tightening the connection screw 202, the crimp terminal 201 is firmly held between the head of the connection screw 202 and the terminal plate 2.

一方、圧着端子２０１を取り外す場合には、接続ネジ２０２を外して圧着端子２０１を端子板２から取り離す。これにより、スライド部材３が圧縮バネ５によってネジ孔２ａ側にスライド、前進し、再びスライド部材３の垂直部３ａがネジ孔２ａを覆う状態となるものである。 On the other hand, when removing the crimp terminal 201, the connection screw 202 is removed and the crimp terminal 201 is detached from the terminal plate 2. As a result, the slide member 3 is slid and moved forward by the compression spring 5 toward the screw hole 2a, and the vertical portion 3a of the slide member 3 again covers the screw hole 2a.

以上のように、この端子台１によれば、圧着端子２０１を押し込まない状態では、垂直部３ａでネジ孔２ａが覆われているため、圧着端子２０１を押し込まずに先端のみを挟んだ状態で接続しようとしても、接続ネジ２０２をネジ孔２ａに螺合させることができない。また、圧着端子２０１を押し込んでスライド部材３を後退させても、圧着端子２０１を所定の位置まで押し込んで、圧着端子２０１の挿入孔２０１ａとネジ孔２ａとを一致させなければ、接続ネジ２０２をネジ孔２ａに螺合させることができない。このように、挿入孔２０１ａとネジ孔２ａとが一致した状態でなければ、接続ネジ２０２を螺合できないため、圧着端子２０１の不適正な接続が防止され、圧着端子２０１を確実、強固に接続することが可能となる。 As described above, according to the terminal block 1, in the state where the crimp terminal 201 is not pushed in, the screw hole 2a is covered with the vertical portion 3a, so that only the tip is sandwiched without pushing the crimp terminal 201. Even if the connection is attempted, the connection screw 202 cannot be screwed into the screw hole 2a. Further, even if the crimping terminal 201 is pushed in and the slide member 3 is retracted, if the crimping terminal 201 is pushed to a predetermined position and the insertion hole 201a and the screw hole 2a of the crimping terminal 201 do not coincide with each other, the connection screw 202 is attached. It cannot be screwed into the screw hole 2a. As described above, since the connection screw 202 cannot be screwed unless the insertion hole 201a and the screw hole 2a coincide with each other, improper connection of the crimp terminal 201 is prevented, and the crimp terminal 201 is securely and firmly connected. It becomes possible to do.

しかも、スライド部材３がスライドして移動するため、圧着端子２０１の押し込みが円滑となり、圧着端子２０１の接続作業を容易に行うことが可能となる。特に、多くの圧着端子２０１を接続する場合には、作業労力、時間を著しく軽減することが可能となる。 Moreover, since the slide member 3 slides and moves, the crimp terminal 201 can be pushed in smoothly, and the crimp terminal 201 can be easily connected. In particular, when many crimp terminals 201 are connected, it is possible to significantly reduce work labor and time.

（実施の形態２）
図６は、この実施の形態に係る端子台１０を示す平面図であり、この実施の形態では、障害体が板バネから構成されている点で実施の形態１と構成が異なり、実施の形態１と同等の構成については、同一符号を付することでその説明を省略する。下記の実施の形態３も同様とする。 (Embodiment 2)
FIG. 6 is a plan view showing the terminal block 10 according to this embodiment. This embodiment is different from the first embodiment in that the obstacle is made of a leaf spring. About the structure equivalent to 1, description is abbreviate | omitted by attaching | subjecting the same code | symbol. The same applies to the following third embodiment.

符号１２は、隣接する端子板２間に設けられた側壁であり、この側壁１２は、圧着端子２０１の押し込み方向Ｘと平行に設けられている。さらに、側壁１２のネジ孔２ａ側（図中右側）には、側壁１２に対して垂直な前壁１３が設けられ、この前壁１３に板バネ（障害体）１１が配設されている。 Reference numeral 12 denotes a side wall provided between adjacent terminal plates 2, and the side wall 12 is provided in parallel with the pressing direction X of the crimp terminal 201. Furthermore, a front wall 13 perpendicular to the side wall 12 is provided on the side of the screw hole 2 a (right side in the drawing) of the side wall 12, and a leaf spring (obstacle) 11 is disposed on the front wall 13.

この板バネ１１は、薄いばね鋼板で構成され、変形自在な帯状で、両端部が側壁１２と前壁１３との角部に固定され、外力が加わらない状態では、ネジ孔２ａ側に曲がったアーチ型・弓なりとなり、図６（ａ）に示すように、ネジ孔２ａの一部を覆うように形成されている。また、圧着端子２０１をネジ孔２ａ側に押し込むと、図６（ｂ）に示すように、板バネ１１が椀型に変形し、圧着端子２０１の挿入孔２０１ａをネジ孔２ａに一致させることができるようになっている。さらに、圧着端子２０１を取り外すと、板バネ１１が復元し、再びネジ孔２ａの一部を覆うものである。 The leaf spring 11 is made of a thin spring steel plate, has a freely deformable band shape, and both end portions are fixed to the corner portions of the side wall 12 and the front wall 13 and bent to the screw hole 2a side when no external force is applied. As shown in FIG. 6A, it is formed to cover part of the screw hole 2a. When the crimp terminal 201 is pushed into the screw hole 2a, the leaf spring 11 is deformed into a bowl shape as shown in FIG. 6B, and the insertion hole 201a of the crimp terminal 201 is made to coincide with the screw hole 2a. It can be done. Further, when the crimp terminal 201 is removed, the leaf spring 11 is restored and covers a part of the screw hole 2a again.

この実施の形態によれば、実施の形態１と同様に、圧着端子２０１の挿入孔２０１ａがネジ孔２ａに一致するまで、圧着端子２０１を押し込まなければ、接続ネジ２０２をネジ孔２ａに螺合させることができない。このため、圧着端子２０１の不適正な接続が防止され、圧着端子２０１を確実、強固に接続することが可能となる。しかも、障害体が板バネ１１から構成されているため、構成が簡易で、容易かつ低コストで端子台１０を製作することが可能となる。さらに、従来の既製の端子台に板バネ１１を取り付けるだけで、容易に端子台１０を構成することができる。 According to this embodiment, as in the first embodiment, the connection screw 202 is screwed into the screw hole 2a unless the crimp terminal 201 is pushed in until the insertion hole 201a of the crimp terminal 201 matches the screw hole 2a. I can't let you. For this reason, improper connection of the crimp terminal 201 is prevented, and the crimp terminal 201 can be securely and firmly connected. In addition, since the obstacle is composed of the leaf spring 11, the terminal block 10 can be manufactured easily and at low cost with a simple configuration. Furthermore, the terminal block 10 can be easily configured simply by attaching the leaf spring 11 to a conventional ready-made terminal block.

（実施の形態３）
図７は、この実施の形態に係る端子台２０を示す平面図であり、この実施の形態では、２つの板バネ２１、２２を備える点で実施の形態２と構成が異なる。 (Embodiment 3)
FIG. 7 is a plan view showing the terminal block 20 according to this embodiment. This embodiment is different from the second embodiment in that the two leaf springs 21 and 22 are provided.

すなわち、板バネ２１、２２は、薄いばね鋼板で構成され、変形自在な帯状で、第１の板バネ２１は、一方の側壁１２に配設され、第２の板バネ２２は、他方の側壁１２に配設されている。そして、外力が加わらない状態では、図７（ａ）に示すように、第１の板バネ２１および第２の板バネ２２の自由端部が、ネジ孔２ａの中央部まで真っ直ぐに延び、ネジ孔２ａの一部を覆うように形成、配設されている。また、圧着端子２０１をネジ孔２ａ側に押し込むと、図７（ｂ）に示すように、両板バネ２１、２２板が反るように変形し、圧着端子２０１の挿入孔２０１ａをネジ孔２ａに一致させることができるようになっている。さらに、圧着端子２０１を取り外すと、板バネ２１、２２が復元し、再びネジ孔２ａの一部を覆うものである。 That is, the leaf springs 21 and 22 are made of thin spring steel plates and have a deformable belt shape. The first leaf spring 21 is disposed on one side wall 12 and the second leaf spring 22 is disposed on the other side wall. 12 is disposed. When no external force is applied, the free ends of the first plate spring 21 and the second plate spring 22 extend straight to the center of the screw hole 2a as shown in FIG. It is formed and arranged so as to cover a part of the hole 2a. Further, when the crimp terminal 201 is pushed into the screw hole 2a side, as shown in FIG. 7B, both the leaf springs 21 and 22 are deformed so as to warp, and the insertion hole 201a of the crimp terminal 201 is changed to the screw hole 2a. Can be matched. Further, when the crimp terminal 201 is removed, the leaf springs 21 and 22 are restored, and a part of the screw hole 2a is covered again.

この実施の形態によれば、実施の形態２と同様に、圧着端子２０１の不適正な接続を防止して、圧着端子２０１を確実、強固に接続することが可能になるとともに、障害体が板バネ２１、２２から構成されているため、構成が簡易となる。しかも、２つの板バネ２１、２２がネジ孔２ａの中央部で分離し、かつそれぞれが別個に変形自在であるため、圧着端子２０１の押し込みが容易となり、圧着端子２０１の接続作業を容易に行うことが可能となる。 According to this embodiment, in the same manner as in the second embodiment, it is possible to prevent the crimp terminal 201 from being improperly connected, and to securely and firmly connect the crimp terminal 201, and the obstacle is a plate. Since the springs 21 and 22 are used, the configuration is simplified. In addition, since the two leaf springs 21 and 22 are separated at the central portion of the screw hole 2a and are individually deformable, the crimp terminal 201 can be easily pushed in, and the crimp terminal 201 can be easily connected. It becomes possible.

以上、この発明の実施の形態について説明したが、具体的な構成は、上記の実施の形態に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があっても、この発明に含まれる。例えば、実施の形態１では、ネジ孔２ａの深さ方向に対してもスライド部材３が存在し、ネジ孔２ａの一部が切り欠かれた状態となっているが、端子板２の上面に板状のスライド部材を配設して、外力が加わらない状態で、スライド部材でネジ孔２ａの全上面またはその一部を覆うようにしてもよい。また、圧着端子２０１の挿入孔２０１ａが円形の場合について説明したが、挿入孔がスリットの場合であっても、適用可能であることは勿論である。 Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the first embodiment, the slide member 3 is also present in the depth direction of the screw hole 2a, and a part of the screw hole 2a is notched. A plate-like slide member may be provided so that the entire upper surface of the screw hole 2a or a part thereof is covered with the slide member in a state where no external force is applied. Further, although the case where the insertion hole 201a of the crimp terminal 201 is circular has been described, it is needless to say that the present invention can be applied even when the insertion hole is a slit.
