Description

【０００１】
【発明の属する技術分野】
本発明は、電気コネクタに係り、詳しくは、多数のコンタクトを狭小ピッチで配設して成る電気コネクタに関する。
【０００２】
【従来の技術】
従来において、例えば、プリント基板１１，１２に表面実装されたコネクタ同士を接続する電気コネクタは、図１０に示すように、細長いコネクタの絶縁ハウジングがあって、その絶縁ハウジングの短手方向に一対に対向配置にされたコンタクト挿入孔が長手方向に多数個列設されて成り、該コンタクト挿入孔にコンタクト８，９が各々圧入されている。
【０００３】
前記コンタクト８，９の一部がプリント基板１１，１２上の回路に半田付けされ、相手方のコンタクトと弾性的に摺接して当接することで、電気的接続が成されている（例えば、特許文献１参照。）。
【０００４】
【特許文献１】
特開平０６−１１１８７３号公報（第１頁乃至第３頁、第１図乃至第３図）
【０００５】
【発明が解決しようとする課題】
しかしながら、電気コネクタの高密度実装化に伴い、隣接するコンタクト間のピッチは、例えばピッチＰ＝０．３〜０．５ｍｍ程度と極めて狭くなってきている。このピッチにおいて、板厚ｔ＝０．１５程度のコンタクトを併設させるので、絶縁ハウジングのコンタクト挿入孔を仕切る隔壁の厚さが０．１５程度の薄肉となって、このモールド成形が困難となってくる。本発明に係る電気コネクタは、このような課題を解決するために提案されたものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、本発明に係る電気コネクタの要旨は、絶縁体と、該絶縁体において横一列に併設して設けられたコンタクト用挿入孔の各々に挿入されたコンタクトとからなる電気コネクタで、前記コンタクトにおける相手方コンタクトとの電気的接続を図る接触部と前記挿入孔に保持される胴体部とにおいて、前記胴体部の厚みが、前記接触部の厚みよりも狭く形成されていることである。そして、絶縁体におけるコンタクト挿入孔を仕切る隔壁において、コンタクトの胴体部の隔壁の厚みが、コンタクトの接続部の隔壁の厚みよりも厚く厚肉にされていることを含むものである。
【０００７】
本発明に係る電気コネクタによれば、コンタクトの接触部は従来通りの、打ち抜いた金属薄板の板厚であって、相手方のコンタクトの接触部と前記板厚範囲内で電気的接触が確保され、その一方で、前記胴体部の厚みはプレスにより押し潰されて、前記板厚よりも狭いので、併設されるコンタクトの胴体部間の肉厚が厚くなり、この部分の絶縁ハウジングを肉厚にすることが可能となり、絶縁ハウジングのモールド成形が可能となる。
【０００８】
【発明の実施の形態】
次に、本発明に係る電気コネクタ１について、図面を参照して説明する。なお、発明の理解を容易にするため、従来例に対応する部分には従来例と同一の符号を付けて説明する。
【０００９】
電気コネクタ１は、図１乃至図３に示すように、絶縁体２と、該絶縁体２において横一列に多数個で対にして併設して設けられたコンタクト用挿入孔２ａの各々に挿入されたコンタクト３とからなる。
【００１０】
図３に示す前記コンタクト３における相手方コンタクトとの電気的接続を図る接触部３ａと、前記挿入孔２ａに厚入によって保持される胴体部３ｂとにおいて、同図（Ｂ），（Ｃ）に示すように、前記胴体部３ｂの厚みｓが、前記接触部３ａの厚みｔよりも狭く形成されている。また、図３（Ａ）に示すように、前記コンタクト３には、この電気コネクタ１を実装するプリント基板１１に設けられた遠近位置のパッド１５，１６（図５（Ｂ）参照）を交互に配置したスタガ配置のパッドに対して、前記遠近位置のパッド１５，１６の両方に接続可能なリード部３ｄ，３ｅを有して形成されている。
【００１１】
このようにコンタクト３を形成するには、図４に示すように、前記胴体部３ｂが、平板状の金属薄板（例えば、ｔ＝０．１５ｍｍ）から所望の形状及び厚さ（例えば、ｓ＝０．１２ｍｍ）にプレスで潰され、その後に、キャリア部３ｃを有してコンタクト全体が打ち抜き切断される。更に、絶縁体２の対向配置の挿入孔２ａ，２ａに一対のコンタクト３，３が圧入される。コンタクト３の挿入後にキャリア部３ｃが切断されて撤去される（図５に示す状態）。なお、一対のコンタクト３，３を挿入孔２ａ，２ａに仮圧入した後に、キャリア部３ｃを切断して、その後に、前記コンタクト３を本圧入する場合もある。
【００１２】
前記胴体部３ｂの板厚ｓが、ｓ＜ｔなので、このコンタクト３を圧入する挿入孔２ａにおいては、図１（Ｂ）及び図２に示すように、挿入孔２ａを仕切る隔壁２ｂの板厚ｃが大きく取れるものである。例えば、ｔ＝０．１５、ピッチＰ＝０．３の場合において、絶縁体２のコンタクト接触部分における隔壁の厚さｂはｂ＝Ｐ−ｔ＝０．１５となって薄肉となるが、コンタクト胴体部分における隔壁２ｂの厚さｃは、ｃ＝Ｐ−ｓ＝０．１８となって厚肉部となる。よって、この絶縁体２の金型を製造するときに、挿入孔部分の製造が容易となる。
【００１３】
このようにして、電気コネクタ１は、図５（Ａ）に示すように、絶縁体２の中央部に設けられた嵌合孔２ｃに、コンタクト３の接続部３ａが対向して臨み、コンタクト３の下部が下面に露出して、プリント基板１１の回路にはんだ接続される。また、絶縁体２の長手方向の側部で上下方向にある貫通孔２ｄには、金属製平板状のホールドダウン１３が固着されて、そのホールドダウン１３の下部が前記プリント基板１１に半田付けされる。
【００１４】
前記プリント基板１１においては、図５（Ｂ）に示すように、前記電気コネクタ１の長手方向において、当該コネクタ１の軸心ｃからの距離で、近距離ａにあるパッド１６と、遠距離ｂにあるパッド１５を、交互に配置してスタガ（千鳥）配置にしたものである。そして、前記軸心ｃを中心にして対称に配置されている。
【００１５】
前記電気コネクタ１を前記プリント基板１１に実装すると、図５（Ｂ）に示すように、コンタクト３の前記リード部３ｅが、遠位置のパッド１５において半田付けされ、前記リード部３ｄが近位置のパッド１６において半田付けされる。こうして、この一つの雄型コンタクト３には、前記リード部３ｄ，３ｅの両方が設けられているので、当該リード部の一方（例えばリード部３ｄ）が半田付けされた場合には、他方のリード部（例えば、接触部３ｅ）は半田付けされず、電気的にパッドと導通することがない。このようにして、プリント基板１１側のパッドをスタガ（千鳥）配置にすることで、狭小ピッチにてコンタクト３を高密度に配列した電気コネクタ１に対して、半田付け表面実装が可能と成るものである。
【００１６】
一方、前記電気コネクタ１と嵌合する他の電気コネクタ４は、図６乃至図８に示すように、一対にして対向配置にしたコンタクト用挿入孔４ｂを長手方向に併設して成る絶縁体４ａと、前記挿入孔４ｂに圧入されるコンタクト５とからなる。また、絶縁体４ａの側部に設けられる上下方向の貫通孔４ｃに金属製平板状のホールドダウン１４が固着されて、その下面がプリント基板１２に半田付けされる。コンタクト５における遠近のリード部５ｂ，５ｃと、プリント基板１２のスタガ配置のパッドとの関係は、前記電気コネクタ１の場合と同様である。こうして、電気コネクタ４がプリント基板１２に固着される。
【００１７】
こうして、前記電気コネクタ１と、他方の電気コネクタ４とを、図９に示すように、嵌合させる。前記コンタクト３の接合部３ａと、コンタクト５の接合部５ａとが摺接して当接し、電気的接続が成される。この場合、前記接続部３ａの左右方向（図９において紙面垂直方向）の幅は、金属製薄板の板厚ｔであり、従来と同様の幅が確保されており、前記接合部５ａとの電気的接合に支障無く、その一方で、コンタクト３の胴体部３ｂの厚さｓが板厚ｔよりも薄くして潰されているので、このコンタクト３を圧入によって支持する絶縁体２側の隔壁２ｂの厚さｃが前記板厚ｔより厚肉にして確保される。よって、絶縁体２の製造が容易になるものである。
【００１８】
【発明の効果】
上記説明したように、本発明に係る電気コネクタは、絶縁体と、該絶縁体において横一列に併設して設けられたコンタクト用挿入孔の各々に挿入されたコンタクトとからなる電気コネクタで、前記コンタクトにおける相手方コンタクトとの電気的接続を図る接触部と前記挿入孔に保持される胴体部とにおいて、前記胴体部の厚みが、前記接触部の厚みよりも狭く形成されているので、このコンタクトを装着する絶縁ハウジングの挿入孔の隔壁の幅を肉厚にすることができて、狭小ピッチのコンタクト挿入孔を有する絶縁体の製造が容易になるものである。
また、絶縁体におけるコンタクト挿入孔を仕切る隔壁において、コンタクトの胴体部の隔壁の厚みが、コンタクトの接続部の隔壁の厚みよりも厚く厚肉にされているので、金型の製造も容易となるものである。

BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector, and more particularly to an electrical connector having a large number of contacts arranged at a narrow pitch.
[0002]
[Prior art]
Conventionally, for example, as shown in FIG. 10, an electrical connector that connects connectors surface-mounted on printed circuit boards 11 and 12 has an insulating housing of an elongated connector, and a pair of the insulating housings in the short direction of the insulating housing. A large number of contact insertion holes arranged in opposition are arranged in the longitudinal direction, and contacts 8 and 9 are press-fitted into the contact insertion holes, respectively.
[0003]
A part of the contacts 8 and 9 is soldered to a circuit on the printed circuit boards 11 and 12, and is brought into elastic contact with the counterpart contact so that electrical connection is established (for example, Patent Documents). 1).
[0004]
[Patent Document 1]
JP-A-06-111873 (first page to third page, FIGS. 1 to 3)
[0005]
[Problems to be solved by the invention]
However, with the high density mounting of electrical connectors, the pitch between adjacent contacts has become extremely narrow, for example, with a pitch P of about 0.3 to 0.5 mm. At this pitch, contacts with a plate thickness t = 0.15 are provided side by side, so that the partition wall partitioning the contact insertion hole of the insulating housing has a thickness of about 0.15, making this molding difficult. come. The electrical connector according to the present invention has been proposed in order to solve such a problem.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, an electrical connector according to the present invention is characterized by an electrical circuit comprising an insulator and contacts inserted in each of contact insertion holes provided side by side in the insulator. In the connector, a thickness of the body portion is smaller than a thickness of the contact portion in a contact portion for electrical connection with the counterpart contact in the contact and a body portion held in the insertion hole. It is. In the partition wall that partitions the contact insertion hole in the insulator, the thickness of the partition wall of the contact body is thicker than that of the partition wall of the contact connection portion.
[0007]
According to the electrical connector according to the present invention, the contact portion of the contact is the thickness of the punched metal thin plate as usual, and electrical contact is ensured within the plate thickness range with the contact portion of the counterpart contact, On the other hand, the thickness of the body portion is crushed by the press and is narrower than the plate thickness, so that the thickness between the body portions of the contacts provided is increased, and the insulating housing of this portion is made thicker. This makes it possible to mold the insulating housing.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, the electrical connector 1 according to the present invention will be described with reference to the drawings. In order to facilitate understanding of the invention, portions corresponding to the conventional example are denoted by the same reference numerals as those of the conventional example.
[0009]
As shown in FIGS. 1 to 3, the electrical connector 1 is inserted into each of the insulators 2 and the contact insertion holes 2 a provided in parallel in a row in the insulator 2. Contact 3.
[0010]
3 (B) and 3 (C) show a contact portion 3a for electrical connection with a counterpart contact in the contact 3 shown in FIG. 3 and a body portion 3b held by insertion into the insertion hole 2a. Thus, the thickness s of the body portion 3b is formed to be narrower than the thickness t of the contact portion 3a. As shown in FIG. 3 (A), the contacts 3 are alternately provided with pads 15 and 16 (see FIG. 5 (B)) at the perspective positions provided on the printed board 11 on which the electrical connector 1 is mounted. The staggered pad is disposed with leads 3d and 3e that can be connected to both the pads 15 and 16 at the far and near positions.
[0011]
In order to form the contact 3 as described above, as shown in FIG. 4, the body portion 3b is formed from a flat metal thin plate (for example, t = 0.15 mm) and has a desired shape and thickness (for example, s = 0.12 mm), and then the entire contact is punched and cut with the carrier portion 3c. Further, a pair of contacts 3 and 3 are press-fitted into the insertion holes 2 a and 2 a arranged opposite to each other in the insulator 2. After the contact 3 is inserted, the carrier portion 3c is cut and removed (the state shown in FIG. 5). In some cases, after the pair of contacts 3 and 3 are temporarily press-fitted into the insertion holes 2a and 2a, the carrier portion 3c is cut, and then the contact 3 is fully press-fitted.
[0012]
Since the thickness s of the body portion 3b is s <t, in the insertion hole 2a into which the contact 3 is press-fitted, as shown in FIGS. 1B and 2, the thickness of the partition wall 2b that partitions the insertion hole 2a. c is large. For example, in the case of t = 0.15 and the pitch P = 0.3, the thickness b of the partition wall at the contact contact portion of the insulator 2 is b = P−t = 0.15 and becomes thin. A thickness c of the partition wall 2b in the body portion is c = P−s = 0.18, which is a thick portion. Therefore, when the mold for the insulator 2 is manufactured, the insertion hole portion can be easily manufactured.
[0013]
In this way, as shown in FIG. 5A, the electrical connector 1 faces the fitting hole 2c provided in the center of the insulator 2 so that the connection portion 3a of the contact 3 faces the contact hole 3c. Is exposed to the lower surface and solder-connected to the circuit of the printed circuit board 11. In addition, a metal flat plate-like holddown 13 is fixed to the through hole 2d in the vertical direction on the side in the longitudinal direction of the insulator 2, and the lower part of the holddown 13 is soldered to the printed circuit board 11. The
[0014]
In the printed circuit board 11, as shown in FIG. 5B, in the longitudinal direction of the electrical connector 1, the distance from the axis c of the connector 1 is a pad 16 at a short distance a and a long distance b. The pads 15 are alternately arranged in a staggered arrangement. And it arrange | positions symmetrically centering | focusing on the said axis c.
[0015]
When the electrical connector 1 is mounted on the printed circuit board 11, as shown in FIG. 5B, the lead part 3e of the contact 3 is soldered at a pad 15 at a far position, and the lead part 3d is placed at a near position. Soldered at the pad 16. Thus, since this male contact 3 is provided with both of the lead portions 3d and 3e, when one of the lead portions (for example, the lead portion 3d) is soldered, the other lead The part (for example, the contact part 3e) is not soldered and is not electrically connected to the pad. In this way, by arranging the pads on the printed circuit board 11 side in a staggered pattern, soldering surface mounting is possible for the electrical connector 1 in which the contacts 3 are arranged with high density at a narrow pitch. It is.
[0016]
On the other hand, as shown in FIGS. 6 to 8, the other electrical connector 4 fitted to the electrical connector 1 has an insulator 4a in which a pair of contact insertion holes 4b arranged opposite to each other are provided in the longitudinal direction. And a contact 5 press-fitted into the insertion hole 4b. Further, a metal plate-like hold-down 14 is fixed to the vertical through-hole 4c provided on the side of the insulator 4a, and the lower surface thereof is soldered to the printed circuit board 12. The relationship between the near and near lead portions 5 b and 5 c in the contact 5 and the staggered pad of the printed circuit board 12 is the same as in the case of the electrical connector 1. Thus, the electrical connector 4 is fixed to the printed circuit board 12.
[0017]
Thus, the electrical connector 1 and the other electrical connector 4 are fitted as shown in FIG. The joint portion 3a of the contact 3 and the joint portion 5a of the contact 5 are brought into sliding contact with each other to establish an electrical connection. In this case, the width of the connecting portion 3a in the left-right direction (the direction perpendicular to the paper surface in FIG. 9) is the thickness t of the metal thin plate, and the same width as in the conventional case is ensured. On the other hand, since the thickness s of the body portion 3b of the contact 3 is crushed to be thinner than the plate thickness t, the partition wall 2b on the insulator 2 side that supports the contact 3 by press-fitting. Is ensured to be thicker than the plate thickness t. Therefore, the insulator 2 can be easily manufactured.
[0018]
【The invention's effect】
As described above, the electrical connector according to the present invention is an electrical connector comprising an insulator and contacts inserted into contact insertion holes provided side by side in the insulator. Since the thickness of the body part is narrower than the thickness of the contact part in the contact part for electrical connection with the counterpart contact in the contact and the body part held in the insertion hole, The width of the partition wall of the insertion hole of the insulating housing to be attached can be increased, and the manufacture of the insulator having the contact insertion holes with a narrow pitch is facilitated.
Further, in the partition wall for partitioning the contact insertion hole in the insulator, the thickness of the partition wall of the contact body is thicker than the thickness of the partition wall of the contact connecting portion, so that the mold can be easily manufactured. Is.
