Description

本発明は、プリント基板等の配線板が有する端子接続部に接続端子を接続する端子接続装置に関する。 The present invention relates to a terminal connection device that connects a connection terminal to a terminal connection portion of a wiring board such as a printed circuit board.

従来より、配線板の一つとしてプリント基板がある。図４は、そのプリント基板１を示しており、このプリント基板１では、絶縁基板２の表面部と裏面部とに配線３が銅箔のパターンで設けられている。配線３は、端部にランド４を端子接続部として有しており、途中部に電子部品５が実装されている。そして、ランド４と絶縁基板２のランド４直下の部分には、それぞれ孔６が共通に形成されており、この孔６に、この場合、コネクタ７が有する接続端子８が裏側から挿通されて、その各挿通突出端部から各ランド４にかけてはんだ９を付着させることにより、接続端子８がはんだ９によってランド４すなわち端子接続部に接続されている。 Conventionally, there is a printed circuit board as one of the wiring boards. FIG. 4 shows the printed circuit board 1. In this printed circuit board 1, wirings 3 are provided in a copper foil pattern on the front surface portion and the back surface portion of the insulating substrate 2. The wiring 3 has a land 4 as a terminal connection portion at an end portion, and an electronic component 5 is mounted in the middle portion. And the hole 6 is formed in common in the land 4 and the part immediately under the land 4 of the insulated substrate 2, and the connection terminal 8 which the connector 7 has in this case is penetrated from the back side to this hole 6, By attaching solder 9 from each insertion protruding end to each land 4, the connection terminal 8 is connected to the land 4, that is, the terminal connection portion by the solder 9.

上記従来のものの場合、プリント基板１のランド４に接続端子８を接続するのに、孔６に接続端子８をプリント基板１の裏側から挿通し、そして、その各挿通突出端部から各ランド４にかけてはんだ９を付着させるという手間が必要であり、組立てが面倒であった。又、その組立てが面倒であるのに加えて、逐一はんだ９を要するために、コスト高ともなっていた。 In the case of the above conventional one, in order to connect the connection terminal 8 to the land 4 of the printed circuit board 1, the connection terminal 8 is inserted into the hole 6 from the back side of the printed circuit board 1, and each land 4 is inserted from each insertion projecting end. It took time and labor to attach the solder 9, and the assembly was troublesome. Moreover, in addition to the troublesome assembly, the solder 9 is required one by one, so that the cost is high.

本発明は上述の事情に鑑みてなされたものであり、従ってその目的は、組立てが簡単にできて、コストの低減も図ることのできる端子接続装置を提供するにある。 The present invention has been made in view of the above-described circumstances, and therefore an object of the present invention is to provide a terminal connection device that can be easily assembled and can be reduced in cost.

上記目的を達成するために、本発明の端子接続装置は、端子接続部を有する配線板のその端子接続部に接続端子を接続するものにおいて、所定の１本又は複数本の接続端子とこれの両側に位置する少なくとも２本の接続端子とを配線板の厚み方向に段違いに設け、この接続端子の段間に配線板を圧挿して、該配線板の前記端子接続部に接続端子を接続するようにしたことを特徴とする。 In order to achieve the above object, a terminal connection device according to the present invention connects a connection terminal to a terminal connection portion of a wiring board having a terminal connection portion. At least two connection terminals located on both sides are provided in steps in the thickness direction of the wiring board, and the wiring board is press-fitted between the stages of the connection terminals, and the connection terminals are connected to the terminal connection portions of the wiring board. It is characterized by doing so.

上記手段によれば、配線板の端子接続部に接続端子を接続するのに、接続端子の段間に配線板を圧挿するだけで足り、はんだも必要とはしない。かくして、組立てを簡単になし得、コストの低減をも達成することができる。 According to the above means, it is only necessary to press-fit the wiring board between the terminals of the connection terminal to connect the connection terminal to the terminal connection portion of the wiring board, and no solder is required. Thus, assembly can be easily performed, and cost reduction can be achieved.

以下、本発明の一実施例（一実施形態）につき、図１ないし図３を参照して説明する。
まず、図３には、配線板１１を示しており、この配線板１１は、この場合、プリント基板であって、絶縁基板１２の表面部と裏面部とにそれぞれ配線１３を銅箔のパターンで設けている。配線１３は、ともに端部にランド１４を端子接続部として有しており、途中部に電子部品１５を実装している。 Hereinafter, an embodiment (one embodiment) of the present invention will be described with reference to FIGS.
First, FIG. 3 shows a wiring board 11. In this case, the wiring board 11 is a printed circuit board, and wirings 13 are respectively formed in a copper foil pattern on the front surface portion and the back surface portion of the insulating substrate 12. Provided. Each wiring 13 has a land 14 as a terminal connection portion at an end portion, and an electronic component 15 is mounted in the middle portion.

これに対して、この場合、コネクタ１６が有する接続端子には、所定の１本又は複数本（この場合、２本）の接続端子１７と、これの両側に位置する少なくとも２本（これも、この場合、２本）の接続端子１８とが存在し、その両者の各端部１７ａ，１８ａを配線板１１の厚み方向に段違いに折曲して設けている。そして、その段間の寸法は、配線板１１の厚みより小さく設定しており、各端部１７ａ，１８ａの位置は配線板１１におけるランド１４の位置に合わせている。 On the other hand, in this case, the connector 16 has one or more predetermined (two in this case) connection terminals 17 and at least two (in this case, both) located on both sides thereof (also, In this case, there are two) connection terminals 18, and both end portions 17 a and 18 a thereof are provided in a stepped manner in the thickness direction of the wiring board 11. The dimension between the steps is set smaller than the thickness of the wiring board 11, and the positions of the end portions 17 a and 18 a are matched with the positions of the lands 14 on the wiring board 11.

この構成で、接続端子１７，１８、特にこれらの各端部１７ａ，１８ａの段間に配線板１１を圧挿すれば、図１及び図２に示すように、配線板１１のランド１４に接続端子１７，１８（これも、特にはそれらの各端部１７ａ，１８ａ）が圧接し、接続される。 In this configuration, if the wiring board 11 is press-fitted between the connection terminals 17 and 18, particularly the end portions 17a and 18a, as shown in FIGS. 1 and 2, the wiring board 11 is connected to the land 14 as shown in FIGS. Terminals 17 and 18 (also in particular their respective ends 17a and 18a) are in pressure contact and connected.

このように本構成のものでは、配線板１１の端子接続部であるランド１４に接続端子１７，１８を接続するのに、接続端子１７，１８の段間に配線板１１を圧挿するだけで足り、従来の、プリント基板１の孔６に接続端子８をプリント基板１の裏側から挿通し、そして、その各挿通突出端部から各ランド４にかけてはんだ９を付着させたもののような面倒もなければ、はんだも必要とはしない。かくして、組立てを簡単になすことができ、コストの低減をも達成することができる。又、はんだ９が含む鉛の使用もなくすことができる。 As described above, in this configuration, in order to connect the connection terminals 17 and 18 to the land 14 which is the terminal connection portion of the wiring board 11, the wiring board 11 is simply press-fitted between the stages of the connection terminals 17 and 18. It is sufficient that the connection terminals 8 are inserted into the holes 6 of the printed circuit board 1 from the back side of the printed circuit board 1 and the solder 9 is adhered to the lands 4 from the respective insertion protruding ends. For example, no solder is required. Thus, the assembly can be easily performed, and the cost can be reduced. Moreover, the use of lead contained in the solder 9 can be eliminated.

なお、接続端子１７は１本でも又は３本以上あっても良く、接続端子１８も３本以上あっても良い。
又、配線板１１は、プリント基板に限られず、絶縁板（インシュレータ）に帯状の金属板など条導体を表面を露出させ埋め込んで成るものであっても良い。
そのほか、本発明は上記し且つ図面に示した実施例にのみ限定されるものではなく、要旨を逸脱しない範囲内で適宜変更して実施し得る。 Note that there may be one connection terminal 17 or three or more connection terminals 17, and there may be three or more connection terminals 18.
Further, the wiring board 11 is not limited to a printed circuit board, but may be a board in which a strip conductor such as a strip-shaped metal plate is exposed and embedded in an insulating board (insulator).
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention.
