Description

本発明は、端子装置、特に基板に実装するねじ端子台を備えた基板実装型端子装置に関する。   The present invention relates to a terminal device, and more particularly to a board-mounted terminal device provided with a screw terminal block mounted on a substrate.

従来の基板実装型端子装置として、ケース体の電線挿入孔を有する端面側でかつ基板への設置面側に、基板に対して離間する切欠きを設け、基板端縁部に印字されているシルク印刷部を視認できるようにすることで、端子台から基板端面までの距離を短くしたものがある（例えば、特許文献１参照）。   As a conventional board-mounted terminal device, a notch that is separated from the board is provided on the end face side of the case body having the electric wire insertion hole and on the installation face side of the board, and the silk printed on the edge of the board There is one in which the distance from the terminal block to the substrate end surface is shortened by making the printed part visible (for example, see Patent Document 1).

特開平６−１４００８４号公報（図１、図２）JP-A-6-140084 (FIGS. 1 and 2)

ところで、基板実装型端子装置においては、製造時のはんだ付け工程において、基板の反りを抑制する目的で、反り防止棒が基板の一側辺部に挿入されて取り付けられる。しかしながら、特許文献１のように、端子台を基板端面に近づけて配置したものにあっては、端子台に反り防止棒が接触してしまうため、反り防止棒を基板にしっかり挿入することができず、反り防止効果が十分ではなかった。   By the way, in a board mounting type terminal device, in a soldering process at the time of manufacture, a warpage preventing rod is inserted and attached to one side of the board for the purpose of suppressing board warpage. However, as in Patent Document 1, in the case where the terminal block is arranged close to the end face of the substrate, the warpage preventing rod comes into contact with the terminal block, so that the warpage preventing rod can be firmly inserted into the substrate. Therefore, the warping prevention effect was not sufficient.

また、反り防止棒を基板にしっかり挿入した場合には、反り防止棒が基板と端子台との間にくさび状に食い込んで、端子台が浮いてしまうことがあった。このため、端子台が反り防止棒と干渉しないように、端子台を基板端面側から後退させて設置せざるを得ないのが実情であった。   In addition, when the warpage prevention rod is firmly inserted into the substrate, the warpage prevention rod may bite in a wedge shape between the substrate and the terminal block, and the terminal block may float. For this reason, the actual situation is that the terminal block has to be set back from the substrate end face side so that the terminal block does not interfere with the warpage prevention rod.

本発明は、前記のような課題を解決するためになされたもので、ねじ端子台をより基板端面に近づけて実装することができる基板実装型端子装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a board-mounted terminal device that can be mounted with a screw terminal block closer to the end face of the board.

本発明に係る基板実装型端子装置は、基板の端子台取付面部に共締めされるねじ端子台を備えた基板実装型端子装置において、ねじ端子台には、その設置面の一側辺部に、基板の端子台取付面部に対向するひさし部を有する切欠きが設けられ、ひさし部と端子台取付面部との間には、ひさし部を保持する別部材で構成される補強部材が設けられているものである。   The board-mounted terminal device according to the present invention is a board-mounted terminal device having a screw terminal block that is fastened together with a terminal block mounting surface portion of the substrate. A notch having an eaves portion facing the terminal block mounting surface portion of the board is provided, and a reinforcing member constituted by another member holding the eaves portion is provided between the eaves portion and the terminal block mounting surface portion. It is what.

本発明に係る基板実装型端子装置においては、ねじ端子台には、その設置面の一側辺部に、基板の端子台取付面部に対向するひさし部を有する切欠きが設けられている。この場合、ねじ締め時にねじ軸方向にかかる力に対してねじ端子台が弱くなってしまう。しかし、本発明に係る基板実装型端子装置においては、さらにひさし部と端子台取付面部との間に、ひさし部を保持する別部材で構成される補強部材を設けているので、弱体化した部分を補強することができる。このため、切欠きを大きく形成することができ、これによって製造時に基板に取り付けられる反り防止棒との干渉を防止しつつ、ねじ端子台をより基板端面に近づけて実装することができて、基板の小型化および小型化によるコスト低減が図れる。   In the board-mounted terminal device according to the present invention, the screw terminal block is provided with a notch having a ridge facing the terminal block mounting surface of the board on one side of the installation surface. In this case, the screw terminal block becomes weak against the force applied in the screw shaft direction during screw tightening. However, in the board-mounted terminal device according to the present invention, a reinforcing member constituted by another member that holds the eaves portion is further provided between the eaves portion and the terminal block mounting surface portion, so that the weakened portion Can be reinforced. For this reason, the notch can be formed large, thereby preventing the interference with the warp prevention rod attached to the substrate at the time of manufacture and mounting the screw terminal block closer to the substrate end surface. The cost can be reduced by downsizing and downsizing.

本発明の実施形態に係る基板実装型端子装置は、図１および図２に示すように、端子相互を締結するねじ１によって基板２の一側辺部の端子台取付面部２ａに共締めされるねじ端子台３を備えている。基板２には、製造時に、その一側辺部に溝形の反り防止棒４が取り付けられる。反り防止棒４は、製造時のはんだ付け工程において、基板２の反りを抑制する目的で取り付けられるものであり、製品段階では、取り外されるものである。 FIG. 1 is a perspective view showing a state where a screw terminal block of a board-mounted terminal device according to an embodiment of the present invention is mounted and a warp prevention rod used in manufacturing is inserted. FIG. 2 is a side view showing a state in which a screw terminal block of the board-mounted terminal device according to the embodiment of the present invention is mounted and a warp prevention rod used in manufacturing is inserted.
As shown in FIG. 1 and FIG. 2, the board-mounted terminal device according to the embodiment of the present invention is fastened together with the terminal block mounting surface 2 a on one side of the board 2 by a screw 1 that fastens the terminals to each other. A screw terminal block 3 is provided. A groove-shaped warpage preventing rod 4 is attached to one side of the substrate 2 at the time of manufacture. The warpage prevention rod 4 is attached for the purpose of suppressing warpage of the substrate 2 in the soldering process during manufacturing, and is removed at the product stage.

図３は本発明の実施形態に係る基板実装型端子装置のねじ端子台の斜視図である。図４は本発明の実施形態に係る基板実装型端子装置のねじ端子台の側面図である。図５は本発明の実施形態に係る基板実装型端子装置のねじ端子台の正面図である。なお、ここでは説明にあたっては前述の図１および図２を参照するものとする。
ねじ端子台３には、図１〜図５に示すように、その設置面の一側辺部に、基板２の端子台取付面部２ａに対向するひさし部５を有する切欠き６が設けられている。切欠き６の奥行き寸法は、製造時に基板２の一側辺部に取り付けられる反り防止棒４の先端縁部４ａが挿入できる寸法に設定されている。つまり、ねじ端子台３は、製造時に反り防止棒４が取り付けられる基板２の一側辺部に切欠き６を向けて実装されている。これによって、反り防止棒４との干渉が防止され、ねじ端子台３を基板端面に近づけて実装することができる。 FIG. 3 is a perspective view of the screw terminal block of the board-mounted terminal device according to the embodiment of the present invention. FIG. 4 is a side view of the screw terminal block of the board-mounted terminal device according to the embodiment of the present invention. FIG. 5 is a front view of the screw terminal block of the board-mounted terminal device according to the embodiment of the present invention. In the description, reference is made to FIG. 1 and FIG. 2 described above.
As shown in FIGS. 1 to 5, the screw terminal block 3 is provided with a notch 6 having an eaves portion 5 facing the terminal block mounting surface portion 2 a of the substrate 2 on one side of the installation surface. Yes. The depth dimension of the notch 6 is set such that the front end edge 4a of the warpage preventing bar 4 attached to one side of the substrate 2 at the time of manufacture can be inserted. That is, the screw terminal block 3 is mounted with the notch 6 facing the one side portion of the substrate 2 to which the warpage preventing rod 4 is attached at the time of manufacture. Thereby, interference with the warpage preventing rod 4 is prevented, and the screw terminal block 3 can be mounted close to the end face of the substrate.

切欠き６は、反り防止棒４との干渉を防止するために必要なものであるが、ねじ締め時にねじ軸方向にかかる力に対してねじ端子台３を弱くする要因となる。そこで、切欠き６の補強が必要となる。   The notch 6 is necessary for preventing interference with the warpage preventing rod 4, but becomes a factor that weakens the screw terminal block 3 with respect to a force applied in the screw shaft direction during screw tightening. Therefore, reinforcement of the notch 6 is necessary.

図６は本発明の実施形態に係る基板実装型端子装置のねじ端子台の切欠きに補強部材を嵌合させた状態を示す側面図である。なお、ここでも説明にあたっては前述の図１および図２を参照するものとする。
図６に示すように、本発明の実施形態に係る基板実装型端子装置は、切欠き６のひさし部５と基板２の端子台取付面部２ａとの間に、ひさし部５を保持する別部材で構成される補強部材７が設けられている。これによって、切欠き６にて弱体化した部分を補強することができ、切欠き６を、例えば製造時に基板２に取り付けられる反り防止棒４の先端縁部４ａから基端側までを覆うように大きく形成することもできる。このため、製造時に基板２に取り付けられる反り防止棒４との干渉を防止しつつ、ねじ端子台３をさらに基板端面に近づけて実装することができ、基板２の小型化および小型化によるコスト低減が図れる。 FIG. 6 is a side view showing a state in which the reinforcing member is fitted into the notch of the screw terminal block of the board-mounted terminal device according to the embodiment of the present invention. In this case as well, the description will be made with reference to FIGS. 1 and 2 described above.
As shown in FIG. 6, the board-mounted terminal device according to the embodiment of the present invention is a separate member that holds the eaves part 5 between the eaves part 5 of the notch 6 and the terminal block mounting surface part 2 a of the board 2. The reinforcement member 7 comprised by these is provided. This makes it possible to reinforce the weakened portion by the notch 6 so that the notch 6 covers, for example, from the leading edge 4a to the base end side of the warpage preventing rod 4 attached to the substrate 2 at the time of manufacture. It can also be formed large. For this reason, it is possible to mount the screw terminal block 3 closer to the end face of the substrate while preventing the interference with the warp preventing rod 4 attached to the substrate 2 at the time of manufacture. Can be planned.
