Description

本発明は、基板のスルーホールに挿入されて使用されるプレスフィット端子に関するものであって、特に振動等による接触不良を防止し、信頼性を向上させることができるプレスフィット端子およびその製造方法に関するものである。 The present invention relates to a press-fit terminal that is used by being inserted into a through-hole of a substrate, and particularly relates to a press-fit terminal that can prevent contact failure due to vibration or the like and improve reliability, and a method for manufacturing the same. Is.

基板のスルーホールに接続させる端子として、半田付けを行わないプレスフィット端子が従来から用いられている。プレスフィット端子では、スルーホールとの接触不良を防止する手段が従来から考案されており、例えば特許文献１では、端子基部にスリットを設けることでスルーホールが磨耗しにくくなるようにしている。 As a terminal to be connected to a through hole of a substrate, a press-fit terminal that does not perform soldering has been conventionally used. For press-fit terminals, a means for preventing contact failure with a through hole has been conventionally devised. For example, in Patent Document 1, a through hole is made hard to wear by providing a slit in a terminal base.

また、特許文献２では、２層以上の基板に接続させるプレスフィット部の幅を先端側から順次大きくしていくことで、先端側のプレスフィット部の接触不良を防止する方法が提案されている。 Patent Document 2 proposes a method for preventing contact failure of the press-fit portion on the tip side by sequentially increasing the width of the press-fit portion to be connected to a substrate having two or more layers from the tip side. .

従来、プレスフィット端子は一枚の金属板を塑性変形して形成されており、プレスフィット部を基板のスルーホールに嵌合させると、前記プレスフィット部は前記スルーホールに接触した形状にさらに変形される。プレスフィット部は、スルーホールとの接触面を工夫した様々な形状がこれまでに提案されている。 Conventionally, a press-fit terminal is formed by plastically deforming a single metal plate. When the press-fit part is fitted into a through-hole of a substrate, the press-fit part is further deformed into a shape in contact with the through-hole. Is done. Various shapes have been proposed so far for the press-fit portion, which are devised for the contact surface with the through hole.

従来のプレスフィット部の形状の例を図５に示す。図５は、スルーホール１０１に挿入された従来のプレスフィット部の断面形状を示す一実施例である。図５（ａ）は、Ｍプレスと呼ばれるもので、プレスフィット部の断面１０２がＭの形状を有している。また、図５（ｂ）と（ｃ）はソリッドタイプと呼ばれるものに属し、それぞれ角ピンタイプ、Ｃ型タイプと呼ばれる。 An example of the shape of a conventional press-fit portion is shown in FIG. FIG. 5 is an example showing a cross-sectional shape of a conventional press-fit portion inserted into the through hole 101. FIG. 5A is called an M press, and the cross section 102 of the press fit portion has an M shape. FIGS. 5B and 5C belong to what is called a solid type, and are called a square pin type and a C type, respectively.

さらに、図５（ｄ）〜（ｇ）はビームタイプと呼ばれるものに属し、それぞれアクションピン、Ｅｙｅ ｏｆ Ｎｅｅｄｌｅ、Σ型タイプ、Ｎ型タイプと呼ばれる。図５に示す断面形状１０２〜１０８を有する従来のプレスフィット端子は、いずれもそれぞれの形状に塑性変形されてスルーホール１０１と接触している。 Further, FIGS. 5D to 5G belong to what is called a beam type, and are called action pins, Eye of Needle, Σ type, and N type, respectively. All of the conventional press-fit terminals having the cross-sectional shapes 102 to 108 shown in FIG. 5 are plastically deformed into respective shapes and are in contact with the through holes 101.

しかしながら、上記従来のプレスフィット端子では、以下のような問題があった。
プレスフィット部は塑性領域まで変形しており、またそのプレスフィット部において、バネ特性が非常に大きいため、スルーホールに挿入後はスルーホール径の変化などに追従できる弾性領域は微少しか残っていなかった。そのため、振動や温度変化などにより、プレスフィット部とスルーホールとの間に一旦隙間ができてしまうと、弾性領域が小さいため該隙間が再び埋められることはなく、プレスフィット部とスルーホールとの接触不良を起こしてしまう。 However, the conventional press-fit terminals have the following problems.
The press-fit part is deformed to the plastic area, and the spring characteristic is very large in the press-fit part, so there is little elastic area that can follow changes in the diameter of the through-hole after insertion into the through-hole. It was. Therefore, once a gap is formed between the press fit part and the through hole due to vibration or temperature change, the elastic region is small and the gap is not filled again. It will cause poor contact.

特許文献１あるいは特許文献２に記載のプレスフィット端子も塑性領域まで変形し、またバネ特性が大きく、微少な弾性領域しか残っていない構造となっている。そのため、温度変化などによりスルーホール径が拡大したり、基板が反ったりした場合、接触する力が急激に弱くなり、振動等で接触不良を発生してしまう恐れがあった。 The press-fit terminal described in Patent Document 1 or Patent Document 2 is also deformed to the plastic region, has a large spring characteristic, and has a structure in which only a small elastic region remains. Therefore, when the through-hole diameter is enlarged due to a temperature change or the substrate is warped, the contact force is suddenly weakened, and there is a possibility that contact failure occurs due to vibration or the like.

そこで、本発明はこれらの問題を解決するためになされたものであり、振動等による接触不良を防止してスルーホールとの良好な接触状態を維持できるプレスフィット端子を提供することを目的とする。 Accordingly, the present invention has been made to solve these problems, and it is an object of the present invention to provide a press-fit terminal capable of preventing a contact failure due to vibration or the like and maintaining a good contact state with a through hole. .

本発明のプレスフィット端子の第１の態様は、基板の導電性スルーホールに挿入されるプレスフィット部を端子基部に備えたプレスフィット端子であって、前記プレスフィット部は、前記スルーホールに接触する接触部と、前記接触部を前記スルーホールに押圧する押圧部とからなることを特徴とするプレスフィット端子である。 A first aspect of the press-fit terminal of the present invention is a press-fit terminal having a press-fit portion to be inserted into a conductive through-hole of a substrate at a terminal base, and the press-fit portion contacts the through-hole. A press-fit terminal comprising: a contact portion that presses the contact portion against the through hole.

本発明の第２の態様は、前記接触部が開口部を有する多角柱状に形成され、前記押圧部が断面を略凹型に形成されて前記開口部に嵌合され、前記接触部の開口部がスルーホールとの接触によって変形するのを、前記押圧部が抑制するように前記接触部を前記スルーホールに押圧することを特徴とするプレスフィット端子である。 According to a second aspect of the present invention, the contact portion is formed in a polygonal column shape having an opening, the pressing portion is formed in a substantially concave shape in section, and is fitted into the opening, and the opening of the contact portion is The press-fit terminal is characterized in that the contact portion is pressed against the through-hole so that the pressing portion suppresses deformation due to contact with the through-hole.

本発明の第３の態様は、前記プレスフィット部を前記端子基部の先端に２つ備えることを特徴とするプレスフィット端子である。 According to a third aspect of the present invention, there is provided a press-fit terminal comprising two press-fit portions at a tip of the terminal base portion.

本発明の第４の態様は、基板の導電性スルーホールに挿入されるプレスフィット部を端子基部に備えたプレスフィット端子の製造方法であって、前記プレスフィット端子は１枚の金属板から加工して製造され、前記プレスフィット部は、開口部を有する多角柱状に成形されその外面が前記スルーホールに接触する接触部と、断面を略凹型に成形され前記接触部を前記スルーホールに押圧する押圧部とをそれぞれ成形し、前記開口部に前記押圧部が嵌合するように前記接触部と前記押圧部との間で折り曲げて成形されることを特徴とするプレスフィット端子の製造方法である。 A fourth aspect of the present invention is a method for manufacturing a press-fit terminal having a press-fit portion inserted into a conductive through hole of a substrate at a terminal base, wherein the press-fit terminal is processed from a single metal plate. The press-fit portion is formed into a polygonal column shape having an opening, and the outer surface of the press-fit portion is in contact with the through hole, and the cross section is formed into a substantially concave shape to press the contact portion against the through hole. It is a manufacturing method of the press fit terminal characterized by shape | molding a press part and bend | folding between the said contact part and the said press part so that the said press part may fit in the said opening part. .

以上説明したように本発明によれば、接触部自体の変形によるスルーホールへの接触力に加えて、押圧部で接触部を基板のスルーホールに押圧するようにしたことにより、振動等による接触不良を防止してスルーホールとの良好な接触状態を維持できるプレスフィット端子およびその製造方法を提供することできる。 As described above, according to the present invention, in addition to the contact force to the through hole due to the deformation of the contact portion itself, the contact portion is pressed against the through hole of the substrate by the pressing portion, so that the contact due to vibration or the like is brought about. It is possible to provide a press-fit terminal capable of preventing a defect and maintaining a good contact state with a through hole, and a manufacturing method thereof.

さらに、接触部と押圧部を１枚の金属板で本発明のプレスフィット端子を形成するようにしたことにより、部品点数を少なくして製造コストを低減することが可能となる。 Furthermore, since the press-fit terminal of the present invention is formed of a single metal plate for the contact portion and the pressing portion, the number of parts can be reduced and the manufacturing cost can be reduced.

図面を参照して本発明の好ましい実施の形態におけるプレスフィット端子の構成について詳細に説明する。なお、同一機能を有する各構成部については、図示及び説明簡略化のため、同一符号を付して示す。 A configuration of a press-fit terminal in a preferred embodiment of the present invention will be described in detail with reference to the drawings. In addition, about each structural part which has the same function, the same code | symbol is attached | subjected and shown for simplification of illustration and description.

図１は、本発明の第一の実施の形態に係るプレスフィット端子の概略構造を示す図である。図１（ａ）はプレスフィット端子１の側面図を示しており、プレスフィット端子１はプレスフィット部２、端子基部３、及びオス端子部４から構成されている。すなわち、端子基部３を中心に、一端側にプレスフィット部２が設けられ、他端側にはオス端子部４が設けられている。 FIG. 1 is a diagram showing a schematic structure of a press-fit terminal according to the first embodiment of the present invention. FIG. 1A shows a side view of the press-fit terminal 1, and the press-fit terminal 1 includes a press-fit portion 2, a terminal base portion 3, and a male terminal portion 4. That is, with the terminal base 3 as the center, the press-fit portion 2 is provided on one end side, and the male terminal portion 4 is provided on the other end side.

プレスフィット部２は、基板のスルーホールに挿入されてオス端子部４を該基板と電気的に接続させるためのものである。図２に、本発明のプレスフィット端子１を基板に接続した状態の断面図の一例を示す。プレスフィット端子１は、プレスフィット部２が基板１１に穿設されたスルーホール１２に挿入されて固定されている。 The press-fit portion 2 is for inserting the male terminal portion 4 into electrical connection with the substrate by being inserted into the through hole of the substrate. In FIG. 2, an example of sectional drawing of the state which connected the press fit terminal 1 of this invention to the board | substrate is shown. The press-fit terminal 1 is fixed by inserting a press-fit portion 2 into a through hole 12 formed in the substrate 11.

プレスフィット部２とスルーホール１２との接触不良を防止するために、プレスフィット部２は図１（ｂ）に示すような構造を有している。図１（ｂ）は、プレスフィット部２の構造を説明するための断面図である。プレスフィット部２は、スルーホール１２と接触容易な形状に形成された接触部５と、その接触部に対して弾性的な挙動をする押圧部６から構成されている。
すなわち、押圧部６は、プレスフィット端子１のオス端子部４の逆側先端７、もしくは端子基部３とプレスフィット部２の境８を中心として、接触部５に対し、弾性的な挙動を発揮する。つまり、図１（ｂ）の上下方向に弾性力が働き、接触部５をスルーホール１２に押圧している。 In order to prevent contact failure between the press-fit portion 2 and the through hole 12, the press-fit portion 2 has a structure as shown in FIG. FIG. 1B is a cross-sectional view for explaining the structure of the press-fit portion 2. The press-fit portion 2 includes a contact portion 5 formed in a shape that can be easily contacted with the through hole 12 and a pressing portion 6 that behaves elastically with respect to the contact portion.
That is, the pressing portion 6 exhibits an elastic behavior with respect to the contact portion 5 around the opposite end 7 of the male terminal portion 4 of the press-fit terminal 1 or the boundary 8 between the terminal base portion 3 and the press-fit portion 2. To do. That is, an elastic force acts in the vertical direction in FIG. 1B to press the contact portion 5 against the through hole 12.

押圧部６は、断面形状が略凹型となるように折り曲げて形成されている。また、接触部５は、開口部を有する多角柱状に形成されており、前記開口部に押圧部６が図１（ｂ）に示すような状態で嵌合されている。 The pressing part 6 is formed by bending so that the cross-sectional shape is substantially concave. Moreover, the contact part 5 is formed in the polygonal column shape which has an opening part, and the press part 6 is fitted by the said opening part in the state as shown in FIG.1 (b).

上記の通り、スルーホールに挿入される際、接触部５が断面に対して縮まる方向に変形するが、押圧部６がそれを抑制すると共に、押圧部６が有する弾性反力によっても、接触部５をスルーホール１２に押圧するように働く。すなわち、接触部５がスルーホールに挿入する際に変形して発生する反力に加えて、押圧部６からも接触部５の開口部を押し広げるように弾性反力が働くことで、接触部５をスルーホール１２に押圧している。 As described above, when the contact portion 5 is inserted into the through hole, the contact portion 5 is deformed in the direction of contraction with respect to the cross section. It works to press 5 to the through hole 12. That is, in addition to the reaction force generated by deformation when the contact portion 5 is inserted into the through hole, an elastic reaction force acts so as to spread the opening of the contact portion 5 from the pressing portion 6. 5 is pressed against the through hole 12.

以上に示したように、接触部５には押圧部６から常に弾性力が加えられるため、自動車等の過酷な使用に対しても、接触部５を常にスルーホール１２に密着させた状態を保持することが可能となる。例えば、従来は車体の振動によって接触部５とスルーホール１２との間に隙間ができてしまうことがあったが、本発明のプレスフィット端子１では、振動によって接触部５とスルーホール１２との間に瞬間的に隙間ができたり、また温度変化によりスルーホール径が拡大しても、押圧部６からの弾性力によって接触部５がスルーホール１２に密着する状態、つまりスルーホール側の変化に追従する状態になる。 As described above, since the elastic force is always applied to the contact portion 5 from the pressing portion 6, the contact portion 5 is always kept in close contact with the through hole 12 even in severe use such as an automobile. It becomes possible to do. For example, conventionally, there has been a gap between the contact portion 5 and the through hole 12 due to vibration of the vehicle body. However, in the press fit terminal 1 of the present invention, the contact portion 5 and the through hole 12 are caused by vibration. Even if a gap is instantaneously formed or the through hole diameter increases due to a temperature change, the contact portion 5 is in close contact with the through hole 12 by the elastic force from the pressing portion 6, that is, the change on the through hole side. It becomes a state to follow.

本発明のプレスフィット端子１は、１枚の金属板を折り重ねた構造としている。図３は、折り重ねる前のプレス成形された１枚の金属板を示している。折り重ねた構造とする事により、押圧部６は、プレスフィット端子１のオス端子部の逆側先端７、もしくは端子基部３とプレスフィット部２の境８を中心として、接触部５に対し、弾性的な挙動を発揮することとなる。また、同図において、好ましくは押圧部６の接触部５に嵌合する部分の外径は、接触部５の押圧部６に嵌合する部分の内径より大きくなっている。 The press-fit terminal 1 of the present invention has a structure in which one metal plate is folded. FIG. 3 shows a single metal sheet press-formed before folding. By adopting a folded structure, the pressing portion 6 is in contact with the contact portion 5 around the opposite end 7 of the male terminal portion of the press-fit terminal 1 or the boundary 8 between the terminal base portion 3 and the press-fit portion 2. It will exhibit elastic behavior. Moreover, in the same figure, the outer diameter of the part fitted to the contact part 5 of the press part 6 is preferably larger than the inner diameter of the part fitted to the press part 6 of the contact part 5.

プレスフィット端子１は、図３に示す１枚の金属板を折り曲げ部２１で折り曲げ、折り曲げ部２１より右側の金属板を左側の金属板に重ね合わせることによって形成される。このとき、接触部５の開口部に押圧部６が嵌合するように重ね合わせる。上述したように、押圧部６の接触部５に嵌合する部分の外径は、接触部５の押圧部６に嵌合する部分の内径より大きくなっていることから、押圧部６から接触部５に対して、断面外側方向に常に力が掛かっている状態にある。但し、押圧部６の外径が接触部５の内径より若干小さい場合においても、スルーホールに挿入すると接触部５は断面内側に縮小して押圧部６に接触し、押圧部６からの弾性反力を得られる事になる。上記の通り本発明のプレスフィット端子１は、１枚の金属板を成形し、折り曲げ部２１で折り曲げて形成されることから、部品点数が少なく製造コストも低くすることができる。 The press-fit terminal 1 is formed by bending one metal plate shown in FIG. 3 at a bent portion 21 and superimposing a metal plate on the right side of the bent portion 21 on the left metal plate. At this time, the pressing portion 6 is overlapped with the opening of the contact portion 5 so as to be fitted. As described above, since the outer diameter of the portion that fits the contact portion 5 of the pressing portion 6 is larger than the inner diameter of the portion that fits the pressing portion 6 of the contact portion 5, 5 is in a state in which a force is always applied in the cross-sectional outer side direction. However, even when the outer diameter of the pressing portion 6 is slightly smaller than the inner diameter of the contact portion 5, when inserted into the through hole, the contact portion 5 contracts to the inside of the cross section and contacts the pressing portion 6, and the elastic reaction from the pressing portion 6 occurs. You will gain power. As described above, the press-fit terminal 1 of the present invention is formed by forming a single metal plate and bending it at the bending portion 21, so that the number of parts is small and the manufacturing cost can be reduced.

本発明の別の実施形態を、図４を用いて以下に説明する。本発明の別の実施形態のプレスフィット端子３１は、図４に示すように、基板３４に接続するためのプレスフィット部を２つ備えたダブルコンタクトプレスフィット方式となっている。プレスフィット部３２，３３は、ともに図１に示したプレスフィット部２と同じ構造を有している。 Another embodiment of the present invention will be described below with reference to FIG. As shown in FIG. 4, the press-fit terminal 31 according to another embodiment of the present invention is a double contact press-fit system having two press-fit portions for connection to the substrate 34. The press fit portions 32 and 33 both have the same structure as the press fit portion 2 shown in FIG.

２つのプレスフィット部３２，３３を備えた本実施形態のプレスフィット端子３１では、基板３４との接続をより確実にすることができ、信頼性を大幅に高めることができる。自動車等の過酷な使用においても、プレスフィット部３２，３３が２つとも振動等によって接触不良となる確率は極めて低くなり、高信頼度のプレスフィット端子を提供することができる。 In the press-fit terminal 31 of this embodiment provided with the two press-fit parts 32 and 33, the connection with the board | substrate 34 can be made more reliable, and reliability can be improved significantly. Even in severe use such as in automobiles, the probability that both of the press-fit portions 32 and 33 are in contact failure due to vibration or the like is extremely low, and a highly reliable press-fit terminal can be provided.

また、プレスフィット部３２，３３のいずれか一方が一時的に接触不良となった場合でも、押圧部６による弾性力で接触部５が再びスルーホール３５または３６に押圧され、良好な接触状態に回復される。さらに、２つのプレスフィット部３２，３３で基板３４と接続されることにより、機械的にも強度が高くなり、振動等によってプレスフィット端子３１が基板３４から離脱する恐れもなくなる。 Even if either one of the press-fit portions 32 and 33 temporarily becomes defective in contact, the contact portion 5 is again pressed against the through-hole 35 or 36 by the elastic force of the pressing portion 6, and a good contact state is obtained. Recovered. Further, since the two press-fit portions 32 and 33 are connected to the substrate 34, the mechanical strength is increased, and there is no possibility that the press-fit terminal 31 is detached from the substrate 34 due to vibration or the like.

図４に示すように、本実施形態ではプレスフィット部を３２と３３の２つとしたことにより、プレスフィット端子３１を基板３４に接続する際に、プレスフィット部３２と３３に均等に荷重をかけるようにしてスルーホール３５、３６に挿入することが可能となる。 As shown in FIG. 4, in this embodiment, the press-fit portions 32 and 33 are used, so that when the press-fit terminal 31 is connected to the substrate 34, a load is evenly applied to the press-fit portions 32 and 33. In this way, it can be inserted into the through holes 35 and 36.

すなわち、プレスフィット部３２と３３をスルーホール３５と３６のそれぞれの上部に配し、端子基部に形成された左右の肩部３７，３８に均等に荷重をかけることで、プレスフィット部３２、３３をスルーホール３５、３６のそれぞれに挿入して嵌合させる。プレスフィット部が２つの場合には、それぞれに均等に荷重をかける事が容易であり、プレスフィット部３２、３３をそれぞれスルーホール３５，３６に十分に嵌合させることができる。 That is, the press-fit portions 32 and 33 are arranged in the upper portions of the through holes 35 and 36, and the load is evenly applied to the left and right shoulder portions 37 and 38 formed in the terminal base portion, so that the press-fit portions 32 and 33 are applied. Are inserted and fitted into the through holes 35 and 36, respectively. When there are two press-fit portions, it is easy to apply a load equally to each of the press-fit portions, and the press-fit portions 32 and 33 can be sufficiently fitted into the through holes 35 and 36, respectively.

なお、本実施の形態における記述は、本発明に係るプレスフィット端子の一例を示すものであり、これに限定されるものではない。本実施の形態におけるプレスフィット端子の細部構成及び詳細な動作等に関しては、本発明の趣旨を逸脱しない範囲で適宜変更可能である。 In addition, the description in this Embodiment shows an example of the press fit terminal which concerns on this invention, and is not limited to this.
