Description

この発明は、基板とケーブル等とを電気的に連結する電気コネクタに関し、特に高速伝送用中継コネクタとして使用され、かつ電磁波による中継部分の障害防止機能を具えた電気コネクタに関する。 The present invention relates to an electrical connector that electrically connects a board and a cable or the like, and more particularly to an electrical connector that is used as a high-speed transmission relay connector and has a function of preventing failure of a relay portion due to electromagnetic waves.

従来から、コンピュータあるいは携帯電話等の電子機器内にはケーブルと基板とを電気的に接続する装置として電気コネクタが使用されている。   Conventionally, an electrical connector is used as an apparatus for electrically connecting a cable and a board in an electronic apparatus such as a computer or a mobile phone.

特に高速伝送用中継コネクタとして使用され、かつ電磁波による中継部分の障害防止機能を具えた電気コネクタとして、シールド機能を有する金属シェルを具えた電気コネクタが知られている。   In particular, an electrical connector having a metal shell having a shielding function is known as an electrical connector that is used as a relay connector for high-speed transmission and has a function of preventing failure of a relay portion due to electromagnetic waves.

図６は上述したシールド機能を有する金属シェルを具えた従来の電気コネクタ１の要部断面図で、特に図示せぬ相手側のプラグコネクタが電気的に接続されるソケットコネクタを示している。   FIG. 6 is a cross-sectional view of a main part of a conventional electrical connector 1 having the above-described metal shell having a shielding function, and particularly shows a socket connector to which a mating plug connector (not shown) is electrically connected.

この電気コネクタ１は図面に垂直な方向に沿って所定のピッチで配設された複数本の導電端子２と、この導電端子２を位置決め収容した絶縁ハウジング３と、この絶縁ハウジング３の周囲を覆うように配設されたシールド機能を有する金属シェル４とから構成されている。   The electrical connector 1 covers a plurality of conductive terminals 2 arranged at a predetermined pitch along a direction perpendicular to the drawing, an insulating housing 3 in which the conductive terminals 2 are positioned and accommodated, and the periphery of the insulating housing 3. It is comprised from the metal shell 4 which has the shielding function arrange | positioned in this way.

また上述した絶縁ハウジング３内には、図示せぬ相手側プラグコネクタの金属シェルと接続するため、独立した別部材である金属製のグランドプレート５が配設されている。 Further, in the insulating housing 3 described above, a metal ground plate 5, which is an independent member, is disposed in order to connect to a metal shell of a mating plug connector (not shown).

なお、このグランドプレート５と前記金属シェル４とは電気的に接触しており、相手側プラグコネクタの金属シェルから前記グランドプレート５に伝達されたグランド信号は、電気的に接触した前記金属シェル４を介し基板のグランド接続端子等へ伝達されるようになっている。 The ground plate 5 and the metal shell 4 are in electrical contact, and the ground signal transmitted from the metal shell of the mating plug connector to the ground plate 5 is electrically contacted with the metal shell 4. The signal is transmitted to the ground connection terminal of the substrate via the.

なお、図６で符号７は図示せぬ相手側プラグコネクタが嵌合する嵌合孔で、前記導電端子２の接点２ａと前記グランドプレート５の接点５ａはいずれも前記嵌合孔７内に突出している。   In FIG. 6, reference numeral 7 denotes a fitting hole into which a mating plug connector (not shown) is fitted, and both the contact 2 a of the conductive terminal 2 and the contact 5 a of the ground plate 5 protrude into the fitting hole 7. ing.

なお、上述した独立した別部材であるグランドプレートを有する従来の金属シェルを具えた電気コネクタは特許第３４５１３９３号にも記載されている。
特許第３４５１３９３号 An electrical connector including a conventional metal shell having a ground plate, which is an independent member described above, is also described in Japanese Patent No. 3451393.
Japanese Patent No. 3451393

ところで、上述した従来の電気コネクタ１によると、グランド信号を伝達するグランドプレート５を独立部品として製造し、これを使用するため、電気コネクタ１全体としての部品点数が多く、このため製造工程も煩雑となってコストアップの要因となっていた。また、グランドプレート５と金属シェル４とは電気的に接触する構造であるから接触不良等が起き易く、このためグランド信号が安定して伝達できない虞もある。     By the way, according to the conventional electrical connector 1 described above, the ground plate 5 for transmitting the ground signal is manufactured as an independent component and used, so that the electrical connector 1 as a whole has a large number of components, and thus the manufacturing process is complicated. It became a factor of cost increase. Further, since the ground plate 5 and the metal shell 4 are in electrical contact with each other, a contact failure or the like is likely to occur, and there is a possibility that the ground signal cannot be stably transmitted.

この発明は、上述した事情に鑑み、部品点数が少なく、しかも安定してグランド信号を伝達することがでる電気コネクタを提供することを目的とする。   In view of the circumstances described above, an object of the present invention is to provide an electrical connector that has a small number of components and can stably transmit a ground signal.

上述した課題を解決するため、この発明では、導電端子を配設した絶縁ハウジングと、該絶縁ハウジングを囲繞する金属シェルとを少なくとも具えた電気コネクタにおいて、前記金属シェルに相手側コネクタの金属シェルと接触する接触バネを一体に形成するようにしている。   In order to solve the above-described problem, according to the present invention, in an electrical connector including at least an insulating housing provided with a conductive terminal and a metal shell surrounding the insulating housing, the metal shell of the mating connector is connected to the metal shell. The contact springs that come into contact with each other are formed integrally.

上述した、本願発明に係る電気コネクタによると、相手側コネクタの金属シェルと接触してグランド信号を伝達するグランドプレートとしての機能を、金属シェルと一体に形成された接触バネにより行なうようにしたから、全体としての部品点数が少なくなり、このため製造工程を減少して安価に電気コネクタを提供することが出来る。また接触バネが金属シェルと一体に形成されているから接触不良もなく、グランド信号を安定して金属シェルに伝達することも出来る。   According to the electrical connector according to the present invention described above, the function as a ground plate for transmitting a ground signal in contact with the metal shell of the mating connector is performed by the contact spring formed integrally with the metal shell. As a result, the number of parts as a whole is reduced, so that the manufacturing process can be reduced and the electrical connector can be provided at a low cost. Further, since the contact spring is formed integrally with the metal shell, there is no contact failure, and the ground signal can be stably transmitted to the metal shell.

以下、この発明に係る電気コネクタの一実施例を詳述する。     Hereinafter, an embodiment of the electrical connector according to the present invention will be described in detail.

図１はこの発明に係る電気コネクタ１０の概念斜視図である。   FIG. 1 is a conceptual perspective view of an electrical connector 10 according to the present invention.

なおこの電気コネクタ１０も後述する相手側のプラグコネクタが電気的に接続されるソケットコネクタを示している。   The electrical connector 10 is also a socket connector to which a mating plug connector described later is electrically connected.

この電気コネクタ１０も従来と同様に長手方向に沿って所定のピッチで配設された複数本の導電端子１１と、この導電端子１１を位置決め収容した矩形状の絶縁ハウジング１２と、この絶縁ハウジング１２の周囲を覆うように配設されたシールド機能を有する金属シェル１３とから構成されている。   The electrical connector 10 also has a plurality of conductive terminals 11 arranged at a predetermined pitch along the longitudinal direction as in the prior art, a rectangular insulating housing 12 in which the conductive terminals 11 are positioned and accommodated, and the insulating housing 12. And a metal shell 13 having a shielding function disposed so as to cover the periphery.

一方、上述した金属シェル１３は、ハウジング１２を除いた概念斜視図で示す図２のように全体が矩形状で、かつ環状に形成されている。   On the other hand, the metal shell 13 described above is formed in a rectangular shape and in an annular shape as shown in FIG. 2 which is a conceptual perspective view excluding the housing 12.

そして、正面１３ａの下面には、当該金属シェル１３と一体に後述する相手側コネクタの金属シェルと接触する接触バネ１４が所定のピッチで複数個（実施例では３個）形成されている。 A plurality of contact springs 14 (three in the embodiment) are formed on the lower surface of the front surface 13a at a predetermined pitch so as to come into contact with a metal shell of a mating connector, which will be described later, integrally with the metal shell 13.

この接触バネ１４は上下方向へ向け弾性的に変位することができる舌片１４ａにより形成され、その先端１４ｂは後述する相手側コネクタの金属シェルとの接触をより一層確実にするため二股状になっている。 This contact spring 14 is formed by a tongue piece 14a that can be elastically displaced in the vertical direction, and its tip 14b has a bifurcated shape in order to further ensure contact with the metal shell of the mating connector described later. ing.

また、電気コネクタ１０の正面図で示す図３のように、接触バネ１４は上方に位置する導電端子１１と対向する位置に形成されており、このため後述する相手側コネクタを導電端子１１と接触バネ１４との間、即ち嵌合部１７の間で挟持する構造となっている。 Further, as shown in FIG. 3, which is a front view of the electrical connector 10, the contact spring 14 is formed at a position facing the conductive terminal 11 located above, so that a mating connector described later contacts the conductive terminal 11. The structure is sandwiched between the spring 14, that is, between the fitting portions 17.

また、図２で示すように、前記接触バネ１４に隣接する位置の金属シェル１３には相手側コネクタの嵌挿を容易にするとともに、金属シェル１３の断面係数を高めてその剛性を向上させる湾曲した舌片１５が複数個形成され、またこの舌片１５間には、図示せぬ基板側のグランド端子と接続するグランド端子１６が形成されている。 Further, as shown in FIG. 2, the metal shell 13 adjacent to the contact spring 14 can be easily inserted into the mating connector, and can be curved to increase the section modulus of the metal shell 13 and improve its rigidity. A plurality of tongue pieces 15 are formed, and a ground terminal 16 connected to a ground terminal on the substrate side (not shown) is formed between the tongue pieces 15.

なお、金属シェル１３の両側方にも図示せぬ基板のグランド端子と接続する矩形状のグランド端子１８が形成されている。 A rectangular ground terminal 18 connected to a ground terminal of a substrate (not shown) is also formed on both sides of the metal shell 13.

なお、図４は図３のＸＸ線拡大断面図である。   4 is an enlarged sectional view taken along line XX of FIG.

この図４に示す位置から図５で示すように、相手側コンタクト、即ち相手側のプラグコネクタ２０を嵌合部１７内に嵌装して接続させると、その導電端子である同軸ケーブル２１の中心導体２２が導電端子１１の接続端子１１ａと接触し、また金属シェル１３の接触バネ１４が同軸ケーブル２１の外部導体２３と接触した金属シェル２４に圧接して接触することとなる。 When the mating contact, that is, the mating plug connector 20 is fitted into the fitting portion 17 and connected as shown in FIG. 5 from the position shown in FIG. 4, the center of the coaxial cable 21 that is the conductive terminal is connected. The conductor 22 comes into contact with the connection terminal 11 a of the conductive terminal 11, and the contact spring 14 of the metal shell 13 comes into pressure contact with the metal shell 24 in contact with the outer conductor 23 of the coaxial cable 21.

したがって、相手側のプラグコネクタ２０の嵌合片２５およびその上下面に配設された中心導体２２と金属シェル２４は、導電端子１１と接触バネ１４との間に挟持され、このため接触バネ１４の弾性定数を適宜設定すれば、相手側のプラグコネクタ２０の金属シェル２４との接触圧を最適に設定して安定したグランド信号伝達を行なうことが出来る。 Therefore, the mating piece 25 of the mating plug connector 20 and the central conductor 22 and the metal shell 24 disposed on the upper and lower surfaces thereof are sandwiched between the conductive terminal 11 and the contact spring 14, and thus the contact spring 14. If the elastic constant is appropriately set, the contact pressure with the metal shell 24 of the mating plug connector 20 can be set optimally to perform stable ground signal transmission.

この発明は、部品点数が少なく、しかも安定してグランド信号を伝達する電気コネクタに適している。   The present invention is suitable for an electrical connector that has a small number of parts and stably transmits a ground signal.
