Description
本発明は自動車等の電子制御機器などに用いられる電気コネクタに関するものである。 The present invention relates to an electrical connector used in an electronic control device such as an automobile.
近年、カーナビゲーションシステム等の自動車の電気装置に内蔵される電子部品やＩＣ（集積回路）等が実装された制御用のプリント基板へ伝送される電気信号は高速化（高周波化）され、また、そのプリント基板の基板パターンも密集し高密度化されてきている。一般的に、このような高周波の電気信号を伝送するために高周波対応のシールド電線が用いられるが、このシールド電線とプリント基板の接続のためにプリント基板に取り付けられる電気コネクタにも高周波化対応の要求がある。 In recent years, electrical signals transmitted to printed circuit boards for control mounted with electronic components and ICs (integrated circuits) incorporated in electrical devices of automobiles such as car navigation systems have been accelerated (increased in frequency). The printed circuit board pattern is also densely packed and densified. In general, a shielded wire for high frequency is used to transmit such a high-frequency electrical signal, but the electrical connector attached to the printed circuit board for connecting the shielded wire to the printed circuit board is also compatible with high frequency. There is a request.
このような電気コネクタにおいて、図２０に示すように、そのコネクタソケット１００は、ソケット側絶縁ハウジング１０２にソケット側電気接触端子１０１を装着してソケット側嵌合部１０３を形成した構成であり、ソケット側電気接触端子１０１はソケット側外部導体１０５とソケット側内部導体１０６を備えており、ソケット側外部導体１０５はシールド外筒１０７を備えている。そして、シールド外筒１０７の両側面部には、切り起こし舌片でばね状のシールド接触端子１０８が形成してある。 In such an electrical connector, as shown in FIG. 20, the connector socket 100 has a configuration in which the socket side electrical contact terminal 101 is attached to the socket side insulating housing 102 to form the socket side fitting portion 103. The side electrical contact terminal 101 includes a socket-side outer conductor 105 and a socket-side inner conductor 106, and the socket-side outer conductor 105 includes a shield outer cylinder 107. Then, on both side portions of the shield outer cylinder 107, spring-like shield contact terminals 108 are formed by cut and raised tongue pieces.
また、図２０に示すように、コネクタプラグ１１０は、プラグ側絶縁ハウジング１１１内にプラグ側電気接触端子１１２を挿入して構成してあり、プラグ側電気接触端子１１２はソケット側内部導体１０６に導通するプラグ側内部導体１１３とプラグ側外部導体１１４を備えていて、プラグ側絶縁ハウジング１１１の先側部で構成するプラグ側嵌合部１１５の内面部とプラグ側外部導体１１４の間のスペース１１６は、ソケット側外部導体１０５とプラグ側外部導体１１４との導通時に変位するシールド接触端子１０８が干渉しないように余裕を持って大きく設定されていた。 As shown in FIG. 20, the connector plug 110 is configured by inserting a plug-side electrical contact terminal 112 into a plug-side insulating housing 111, and the plug-side electrical contact terminal 112 is electrically connected to the socket-side internal conductor 106. The plug-side inner conductor 113 and the plug-side outer conductor 114 are provided, and a space 116 between the inner surface portion of the plug-side fitting portion 115 and the plug-side outer conductor 114 formed by the front side portion of the plug-side insulating housing 111 is The shield contact terminal 108 that is displaced when the socket-side outer conductor 105 and the plug-side outer conductor 114 are electrically connected to each other is set large enough with a margin.
そして、図２１に示すように、ソケット側嵌合部１０３にプラグ側嵌合部１１５を嵌合して、ソケット側内部導体１０６をプラグ側内部導体１１３に接触させて両内部導体１０６，１１３の導通を行い、プラグ側外部導体１１４の両側壁部を、ソケット側外部導体１０５のシールド接触端子１０８に接触させて、両外部導体１０５，１１４の導通を行なうが、この導通時において、シールド接触端子１０８の先側は外方に変位してスペース１１６に挿入されるようになる（特許文献１参照）。 Then, as shown in FIG. 21, the plug-side fitting portion 115 is fitted into the socket-side fitting portion 103, and the socket-side inner conductor 106 is brought into contact with the plug-side inner conductor 113, so that both the inner conductors 106, 113 are connected. Conduction is performed and both side wall portions of the plug-side outer conductor 114 are brought into contact with the shield contact terminal 108 of the socket-side outer conductor 105 to conduct both the outer conductors 105 and 114. At this conduction, the shield contact terminal The front side of 108 is displaced outward and inserted into the space 116 (see Patent Document 1).
また、従来の電気コネクタとして、プリント基板に実装される基板コネクタと、この基板コネクタの嵌合接続の相手側コネクタとしてのケーブルコネクタとを有するものがある。そして、基板コネクタは、相手側コネクタを受け入れる受入室を有する誘電体と、この誘電体を収容する基板コネクタ側外導体シェルとを備え、この基板コネクタ側外導体シェルの誘電体の外周を覆う本体部には接触片が設けてある。 Some conventional electrical connectors include a board connector mounted on a printed circuit board and a cable connector as a mating connector for mating connection of the board connector. The board connector includes a dielectric having a receiving chamber for receiving the mating connector and a board connector-side outer conductor shell that accommodates the dielectric, and covers the outer periphery of the dielectric of the board connector-side outer conductor shell. The part is provided with a contact piece.
また、ケーブルコネクタでは、ハウジングに収容されたケーブルコネクタ側外導体シェルの本体部の左、右側壁と、ハウジングの収容室の左、右側壁との間に挿入溝が形成してあり、これらの挿入溝に基板コネクタ側外導体シェルの接触片が挿入されるようになっている。 Further, in the cable connector, insertion grooves are formed between the left and right side walls of the cable connector side outer conductor shell housed in the housing and the left and right side walls of the housing housing chamber. A contact piece of the board connector side outer conductor shell is inserted into the insertion groove.
そして、ケーブルコネクタを基板コネクタに嵌合すると、ケーブルコネクタのケーブルコネクタ側内部導体に基板コネクタ側内部導体が挿入されて弾性的に接触することで電気的に接続されると共に、ケーブルコネクタに形成された挿入溝に、基板コネクタ側外導体シェルの接触片が挿入されて、ケーブルコネクタ側外導体シェルの外面に接触片が弾性的に接触することで、ケーブル側外導体シェルと基板側外導体シェルは電気的に接続される（特許文献２参照）。 When the cable connector is fitted to the board connector, the board connector-side inner conductor is inserted into the cable connector-side inner conductor of the cable connector and is electrically connected by elastic contact, and is formed in the cable connector. When the contact piece of the board connector side outer conductor shell is inserted into the inserted groove and the contact piece elastically contacts the outer surface of the cable connector side outer conductor shell, the cable side outer conductor shell and the board side outer conductor shell Are electrically connected (see Patent Document 2).
上記した従来の前者の電気コネクタにあっては、プラグ側嵌合部１１５の内面部とプラグ側外部導体１１４との間のスペース１１６は、ソケット側外部導体１０５とプラグ側外部導体１１４との導通時に変位するシールド接触端子１０８が干渉しないように余裕を持って大きく設定されているために、強度面やこじり対応等からハウジングについて、所定の肉厚が要求される自動車等の電子制御機器などに用いられる電気コネクタにおいては、必然的に、プラグ側嵌合部１１５の幅寸法が大きくなる。このために、プラグ側嵌合部１１５が嵌合するソケット側嵌合部１０３を大きくする必要があって、ソケット側絶縁ハウジング１０２の幅寸法が大きくなり、電気コネクタ全体の寸法が大きくなって、小型化を困難にしているという課題があった。 In the above-described conventional electrical connector, the space 116 between the inner surface portion of the plug-side fitting portion 115 and the plug-side outer conductor 114 is connected to the socket-side outer conductor 105 and the plug-side outer conductor 114. Since the shield contact terminal 108 that is displaced sometimes is set large enough so as not to interfere, it is suitable for electronic control devices such as automobiles that require a predetermined thickness for the housing from the standpoint of strength and twisting. In the electrical connector used, the width dimension of the plug-side fitting portion 115 is inevitably increased. For this reason, it is necessary to enlarge the socket-side fitting portion 103 into which the plug-side fitting portion 115 is fitted, the width dimension of the socket-side insulating housing 102 is increased, and the overall size of the electrical connector is increased. There was a problem of making miniaturization difficult.
また、従来の前者の電気コネクタを、上記した自動車等の電気コネクタとして用いる場合には、所定の電線固着力が要求される関係上、ケーブル径を小さくできないので、単純にプラグ側電気接触端子１１２の小型化ができず、電気コネクタ全体の寸法が大きくなって、小型化を困難にしているという課題があった。 In addition, when the former former electrical connector is used as an electrical connector for the above-described automobile or the like, the cable diameter cannot be reduced because a predetermined electric wire fixing force is required. Therefore, the plug-side electrical contact terminal 112 is simply used. The size of the entire electrical connector is increased, making it difficult to reduce the size.
また、上記した従来の後者の電気コネクタにあっては、ケーブルコネクタにおいて、ハウジングに収容されたケーブルコネクタ側外導体シェルの本体部の左、右側壁と、ハウジングの収容室の左、右側壁との間に挿入溝が形成してあり、この挿入溝に基板コネクタ側外導体シェルの接触片が挿入されるようになっている。したがって、この挿入溝に、基板コネクタ側外導体シェルの接触片が挿入されて、ケーブルコネクタ側外導体シェルの外面に接触片が弾性的に接触した場合、この接触片は外方に開くように変位するために、接触片がハウジングの収容室の左、右側壁に干渉しないように、挿入溝を、余裕を持って大きく設定しなければならず、このために、ハウジングの収容室の幅寸法が大きくなり、電気コネクタ全体の寸法が大きくなって、小型化を困難にしており、また、接触片がハウジングの収容室の左、右側壁に干渉しないように、接触片の先端の誘いを小さくすることにより、嵌合の際の座屈のおそれもでてくるという課題があった。 Further, in the above-described conventional latter electrical connector, in the cable connector, the left and right side walls of the main body of the cable connector side outer conductor shell housed in the housing, and the left and right side walls of the housing chamber of the housing An insertion groove is formed in between, and a contact piece of the board connector side outer conductor shell is inserted into this insertion groove. Therefore, when the contact piece of the board connector side outer conductor shell is inserted into the insertion groove and the contact piece elastically contacts the outer surface of the cable connector side outer conductor shell, the contact piece opens outward. In order to displace, the insertion groove has to be set large enough with a margin so that the contact piece does not interfere with the left and right side walls of the housing chamber of the housing. The size of the electrical connector as a whole is increased, making it difficult to reduce the size of the electrical connector. In addition, the invitation of the tip of the contact piece is reduced so that the contact piece does not interfere with the left and right side walls of the housing chamber. As a result, there is a problem that buckling may occur during fitting.
本発明は上記の課題を解決した上で、小型化が可能になる電気コネクタを提供することである。 An object of the present invention is to provide an electrical connector that can be miniaturized after solving the above-described problems.
上記の目的を達成するために、本発明に係る電気コネクタは、コネクタソケットと、このコネクタソケットに挿抜可能に結合されるコネクタプラグを備えた電気コネクタであって、コネクタソケットは、そのソケット側電気接触端子にソケット側外部導体を備えていると共に、このソケット側外部導体はばね片形状のシールド接触端子を有し、且つソケット側絶縁ハウジングはソケット側嵌合部を備えており、コネクタプラグは、そのプラグ側電気接触端子にプラグ側外部導体を備えていて、このプラグ側外部導体にシールド接触端子を接触させて、ソケット側電気接触端子との導通を行う構成であり、且つプラグ側絶縁ハウジングは、ソケット側嵌合部に嵌合されるプラグ側嵌合部を備えており、このプラグ側嵌合部の内面部とプラグ側外部導体との間のスペースをシールド接触端子が入る程度に狭めると共に、内面部に、導通時に変位するシールド接触端子との干渉を避けるための干渉回避スペースを設けるようにしたことを特徴とする。 In order to achieve the above object, an electrical connector according to the present invention is an electrical connector comprising a connector socket and a connector plug that is removably coupled to the connector socket. The contact terminal has a socket-side outer conductor, the socket-side outer conductor has a spring-shaped shield contact terminal, and the socket-side insulating housing has a socket-side fitting portion.

かかる構成により、プラグ側嵌合部の内面部とプラグ側外部導体との間のスペースをシールド接触端子が入る程度に狭めると共に、プラグ側嵌合部の内面部に、導通時に変位するシールド接触端子との干渉を避けるための干渉回避スペースが設けてあるために、プラグ側嵌合部の幅寸法が小さくなって、プラグ側絶縁ハウジングの幅寸法を小さくすることが可能になり、コネクタプラグ全体の寸法が小さくなって、電気コネクタ全体の小型化が可能になる。 With this configuration, the space between the inner surface portion of the plug-side fitting portion and the plug-side outer conductor is narrowed to the extent that the shield contact terminal can be inserted, and the shield contact terminal that is displaced when conducting on the inner surface portion of the plug-side fitting portion. Because the interference avoidance space is provided to avoid interference with the plug side, the width of the plug-side fitting portion is reduced, and the width of the plug-side insulating housing can be reduced. The size is reduced, and the entire electrical connector can be reduced in size.
また、本発明に係る電気コネクタは、上記した本発明に係る電気コネクタにおいて、干渉回避スペースは、シールド接触端子が接触するプラグ側外部導体の端子接触部位に対向するプラグ側嵌合部の内面部に形成した凹溝であることを特徴とする。 Further, the electrical connector according to the present invention is the above-described electrical connector according to the present invention, wherein the interference avoidance space is an inner surface portion of the plug-side fitting portion facing the terminal contact portion of the plug-side outer conductor with which the shield contact terminal contacts. It is the concave groove formed in this.
かかる構成により、プラグ側外部導体の端子接触部位に対向するプラグ側嵌合部の内面部に凹溝を形成して、当該凹溝がなす空間が干渉回避スペースにしてあるために、プラグ側嵌合部の幅寸法が小さくなって、プラグ側絶縁ハウジングの幅寸法が小さくなり、コネクタプラグ全体の寸法が小さくなって、電気コネクタの小型化が可能になる。 With this configuration, a concave groove is formed on the inner surface of the plug-side fitting portion that faces the terminal contact portion of the plug-side outer conductor, and the space formed by the concave groove serves as an interference avoidance space. The width dimension of the joint portion is reduced, the width dimension of the plug-side insulating housing is reduced, the overall dimensions of the connector plug are reduced, and the electrical connector can be miniaturized.
また、本発明に係る電気コネクタは、上記した本発明に係る電気コネクタにおいて、プラグ側電気接触端子は、プラグ側外部導体のコンタクト保持部内に絶縁体を介してプラグ側内部導体を収容保持し、且つシールド電線を圧着するシールド電線圧着部を有しており、コンタクト保持部の径をシールド電線圧着部の径より小さく選択し、コンタクト保持部が挿入されるプラグ側嵌合部の径をコンタクト保持部の径に合わせた大きさに選択するようにしたことを特徴とする。 Further, the electrical connector according to the present invention is the electrical connector according to the present invention described above, wherein the plug-side electrical contact terminal accommodates and holds the plug-side inner conductor via an insulator in the contact holding portion of the plug-side outer conductor, In addition, it has a shielded wire crimping part that crimps the shielded wire, selects the diameter of the contact holding part smaller than the diameter of the shielded wire crimping part, and holds the diameter of the plug-side fitting part into which the contact holding part is inserted. The size is selected according to the diameter of the part.
かかる構成により、電線固着力の関係上、シールド電線のケーブル径を小さくできないが、プラグ側電気接触端子のコンタクト保持部の径をシールド電線圧着部の径より小さく選択し、このコンタクト保持部が挿入されるプラグ側嵌合部の径をコンタクト保持部の径に合わせて小さく選択することで、コネクタプラグ全体の寸法が小さくできて、電気コネクタＡ全体の小型化が可能になる。 With this configuration, the cable diameter of the shielded wire cannot be reduced due to the wire adhering force, but the diameter of the contact holding portion of the plug-side electrical contact terminal is selected to be smaller than the diameter of the shielded wire crimping portion, and this contact holding portion is inserted. By selecting the diameter of the plug-side fitting portion to be small according to the diameter of the contact holding portion, the overall size of the connector plug can be reduced, and the electrical connector A as a whole can be downsized.
本発明に係る電気コネクタによれば、プラグ側嵌合部の内面部とプラグ側外部導体との間のスペースをシールド接触端子が入る程度に狭めると共に、プラグ側嵌合部の内面部に、導通時に変位するシールド接触端子との干渉を避けるための干渉回避スペースが設けてあるために、プラグ側嵌合部の幅寸法が小さくなって、プラグ側絶縁ハウジングの幅寸法を小さくすることが可能になり、コネクタプラグ全体の寸法が小さくなって、電気コネクタ全体の小型化が可能になる。 According to the electrical connector of the present invention, the space between the inner surface portion of the plug-side fitting portion and the plug-side outer conductor is narrowed to the extent that the shield contact terminal can be inserted, and the inner surface portion of the plug-side fitting portion is electrically connected. Interference avoidance space is provided to avoid interference with shield contact terminals that sometimes displace, so the width dimension of the plug-side mating part can be reduced and the width dimension of the plug-side insulating housing can be reduced. Thus, the overall size of the connector plug is reduced, and the entire electrical connector can be reduced in size.

また、本発明に係る電気コネクタによれば、電線固着力の関係上、シールド電線のケーブル径を小さくできないが、プラグ側電気接触端子のコンタクト保持部の径をシールド電線圧着部の径より小さく選択し、このコンタクト保持部が挿入されるプラグ側嵌合部の径をコンタクト保持部の径に合わせて小さく選択することで、コネクタプラグ全体の寸法が小さくできて、電気コネクタ全体の小型化が可能になる。 Further, according to the electrical connector according to the present invention, the cable diameter of the shielded electric wire cannot be reduced due to the wire fixing force, but the diameter of the contact holding portion of the plug-side electric contact terminal is selected to be smaller than the diameter of the shielded electric wire crimping portion. And, by selecting the diameter of the plug-side fitting part into which this contact holding part is inserted to be small according to the diameter of the contact holding part, the size of the entire connector plug can be reduced and the entire electrical connector can be downsized. become.
電気コネクタの小型化を可能にするという目的を、プラグ側嵌合部の内面部とプラグ側外部導体との間のスペースをシールド接触端子が入る程度に狭めると共に、プラグ側嵌合部の内面部に、導通時に変位するシールド接触端子との干渉を避けるための干渉回避スペースを形成する凹溝を設けることで実現した。 The purpose of enabling the miniaturization of the electrical connector is to narrow the space between the inner surface of the plug-side fitting portion and the plug-side outer conductor to the extent that the shield contact terminal can be inserted, and the inner surface portion of the plug-side fitting portion. This is realized by providing a concave groove that forms an interference avoidance space for avoiding interference with the shield contact terminal that is displaced during conduction.

コネクタソケットＢは、その実装面をプリント基板の実装面（いずれも図示せず）に接触させて、ソケット側内部導体４３の接続端子５７とソケット側外部導体４２のシールド端子５５をプリント基板に設けたスルーホールに挿入して半田付けによりそれぞれの回路パターン（いずれも図示せず）に接触させてプリント基板に実装してある。 The connector socket B has its mounting surface in contact with the mounting surface of the printed circuit board (both not shown), and the connection terminal 57 of the socket-side inner conductor 43 and the shield terminal 55 of the socket-side outer conductor 42 are provided on the printed circuit board. The printed circuit board is mounted on a printed circuit board by being inserted into the through-holes and brought into contact with each circuit pattern (not shown) by soldering.
そして、コネクタプラグＡとコネクタソケットＢとの結合は次のようにして行なわれる。すなわち、図４及び図５に示すように、コネクタソケットＢのソケット側嵌合部４４にコネクタプラグＡのプラグ側嵌合部３を嵌合して、ソケット側内部導体４３のコンタクト部５６をプラグ側内部導体１２のコンタクト部２２に接触させて両内部導体４３，１２の導通を行い、プラグ側外部導体１０におけるコンタクト保持部１３の端子接触部位１３Ｂを、ソケット側外部導体４２のシールド接触端子５４に接触させて、両外部導体１０，４２の導通を行ない、コネクタプラグＡのロックレバー８をコネクタソケットＢのロックレバー挿入部４５に挿入して、これの係止孔部４６にロック用係止突起部９を係止しロック状態にする。 The connector plug A and the connector socket B are connected as follows.

The front side of the contact terminal 54 opens outward and is inserted into the interference avoidance clearance formed by the concave groove 6 of the plug-side fitting portion 3. For this reason, the front side (guide part 54a) of the shield contact terminal 54 is prevented from bottoming.
以上説明したように、本発明に係る電気コネクタの実施例１によれば、プラグ側嵌合部３の内面部３ａ，３ｂとコンタクト保持部１３との間の空間を、ソケット側外部導体４２のシールド接触端子５４が入る程度に狭めたソケット側外部導体挿入用のスペースＳにしてあり、また、シールド接触端子５４が接触するプラグ側外部導体１０の端子接触部位１３Ｂはプラグ側嵌合部３の両側の内面部３ａ，３ｂに対向しており、これらの内面部３ａ，３ｂに凹溝６を形成して、当該凹溝６がなす空間が、導通時に変位するシールド接触端子５４との干渉（底付き）を避けるための干渉回避スペースにしてあるために、プラグ側嵌合部３の幅寸法を小さくすることができて、プラグ側絶縁ハウジング１の幅寸法が小さくなり、コネクタプラグＡ全体の寸法が小さくなって、電気コネクタの小型化が可能になる。 As described above, according to the first embodiment of the electrical connector according to the present invention, the space between the inner surface portions 3a and 3b of the plug-side fitting portion 3 and the contact holding portion 13 is set to the socket-side outer conductor 42. The space S for inserting the socket-side outer conductor is narrowed to the extent that the shield contact terminal 54 is inserted, and the terminal contact portion 13B of the plug-side outer conductor 10 with which the shield contact terminal 54 contacts is the plug-side fitting portion 3. The inner surface portions 3a and 3b on both sides are opposed to each other, and a concave groove 6 is formed in the inner surface portions 3a and 3b, and the space formed by the concave groove 6 interferes with the shield contact terminal 54 that is displaced during conduction ( The width of the plug-side fitting portion 3 can be reduced, the width of the plug-side insulating housing 1 is reduced, and the connector plug A as a whole. Size is decreased, it is possible to miniaturize the electrical connector.
上記実施例においては、コネクタプラグＡ側がケーブル結線タイプのコネクタとなり、コネクタソケットＢ側が基板実装タイプのコネクタとなるように構成しているが、これに限定されるものではなく、例えば、コネクタプラグＡ側を基板実装タイプとするとともにコネクタソケットＢ側をケーブル結線タイプにしてもよく、また、コネクタプラグＡ及びコネクタソケットＢの両方をともに、ケーブルタイプ若しくは基板実装タイプのものとして構成するようにしてもよい。 In the above embodiment, the connector plug A side is a cable connection type connector and the connector socket B side is a board mounting type connector. However, the present invention is not limited to this. For example, the connector plug A The side may be a board mounting type and the connector socket B side may be a cable connection type, and both the connector plug A and the connector socket B may be configured as a cable type or a board mounting type. Good.
また、本発明に係る電気コネクタの実施例２では、プラグ側外部導体１０におけるコンタクト保持部１３の径をシールド電線圧着部１９の径より小さく選択し、コンタクト保持部１３が挿入されるプラグ側嵌合部３の径をコンタクト保持部１３の径に合わせた大きさに選択するようにしたものである。なお、他の構成及び作用は上記した本発明に係る電気コネクタの実施例１のものと同様であるために、説明を省略する。 Further, in the second embodiment of the electrical connector according to the present invention, the diameter of the contact holding portion 13 in the plug-side outer conductor 10 is selected to be smaller than the diameter of the shielded wire crimping portion 19, and the plug-side fitting into which the contact holding portion 13 is inserted. The diameter of the joint portion 3 is selected to match the diameter of the contact holding portion 13. In addition, since the other structure and effect | action are the same as that of the thing of Example 1 of the above-mentioned electrical connector which concerns on this invention, description is abbreviate | omitted.
すなわち、図１９に示すように、プラグ側絶縁ハウジング１には、正面四角形状で枠形のプラグ側嵌合部３と電気接触端子挿入部４が設けてあり、電気接触端子挿入部４の大きさは、電気接触端子挿入部４に挿入されるプラグ側電気接触端子２のシールド電線圧着部１９の大きさで決まる。また、プラグ側嵌合部３は、絶縁体１１を小さくできれば、細くすることができる。 That is, as shown in FIG. 19, the plug-side insulating housing 1 is provided with a plug-side fitting portion 3 and an electric contact terminal insertion portion 4 which are rectangular in shape and have a front shape. The length is determined by the size of the shielded wire crimping portion 19 of the plug-side electrical contact terminal 2 inserted into the electrical contact terminal insertion portion 4. Further, the plug-side fitting portion 3 can be thinned if the insulator 11 can be made small.
例えば、φ３のシールド電線Ｕを使用できるようにすると、電気接触端子挿入部４はφ３以上の大きさが必要になる。しかし、嵌合した時にソケット側嵌合部４４に入り込むプラグ側嵌合部３だけφ３よりも小さくすれば、プラグ側絶縁ハウジング１全体を小型化することができる。 For example, when a shielded wire U with φ3 can be used, the electrical contact terminal insertion portion 4 needs to have a size of φ3 or more. However, if only the plug-side fitting portion 3 that enters the socket-side fitting portion 44 when fitted is made smaller than φ3, the entire plug-side insulating housing 1 can be reduced in size.
仮にφ３のシールド電線Ｕが入る電気接触端子挿入部４部分のプラグ側絶縁ハウジング１の壁の厚みを１ｍｍとするとφ５になる。それがプラグ側嵌合部３の壁も１ｍｍとするとφ７になってしまう。しかし、プラグ側電気接触端子２のコンタクト保持部１３をφ１ｍｍで作ることが出来れば、壁を１ｍｍにしてもφ３でプラグ側嵌合部３をφ５にできる。 If the thickness of the wall of the plug-side insulating housing 1 in the electric contact terminal insertion portion 4 portion into which the shielded wire U of φ3 enters is 1 mm, it becomes φ5. If the wall of the plug-side fitting portion 3 is also 1 mm, it becomes φ7. However, if the contact holding portion 13 of the plug-side electrical contact terminal 2 can be made with φ1 mm, the plug-side fitting portion 3 can be made φ5 with φ3 even if the wall is 1 mm.
本発明に係る電気コネクタの実施例２によれば、電線固着力の関係上、シールド電線Ｕのケーブル径を小さくできないが、プラグ側電気接触端子２のコンタクト保持部１３の径をシールド電線圧着部１９の径より小さく選択し、コンタクト保持部１３が挿入されるプラグ側嵌合部３の径をコンタクト保持部１３の径に合わせて小さく選択することで、コネクタプラグＡ全体の寸法が小さくできて、電気コネクタ全体の小型化が可能になる。 According to the second embodiment of the electrical connector according to the present invention, the cable diameter of the shielded electric wire U cannot be reduced due to the electric wire fixing force, but the diameter of the contact holding portion 13 of the plug-side electric contact terminal 2 is changed to the shielded electric wire crimping portion. By selecting a diameter smaller than 19 and selecting the diameter of the plug-side fitting portion 3 into which the contact holding portion 13 is inserted to be smaller according to the diameter of the contact holding portion 13, the overall size of the connector plug A can be reduced. The entire electrical connector can be downsized.
本発明に係る電気コネクタは、所定の強度を確保しつつ小型化が可能になるという効果を有し、自動車用電子機器、携帯電話機等の情報端未機器等に搭載されて、その入、出力部等に用いられる同軸コネクタ等として有用である。 The electrical connector according to the present invention has an effect that it can be miniaturized while ensuring a predetermined strength, and is mounted on an information terminal device such as an automobile electronic device or a mobile phone, and its input / output It is useful as a coaxial connector or the like used for a part or the like.
