Description

本発明は、シールド電線に接続されるシールドコネクタコネクタに関し、更に詳しくはシールド電線の端末に接続されるコネクタ端子のインピーダンス整合が図られたシールドコネクタに関する。   The present invention relates to a shield connector connector connected to a shielded wire, and more particularly to a shield connector in which impedance matching of a connector terminal connected to a terminal of a shielded wire is achieved.

近年、自動車、ＯＡ機器、家電製品等を中心に高性能、多機能化が急速に進められてきており、それに伴い伝送される電気信号は高速度化・高周波化されてきている。一般に、このような高周波の電気信号を伝送するためには同軸ケーブルからなるシールド電線が用いられるが、伝送される電気信号の高周波化に伴って、このシールド電線に接続されるシールドコネクタにも高周波特性の向上の要求が高まっている。   2. Description of the Related Art In recent years, high performance and multi-functionality have been rapidly advanced mainly in automobiles, OA equipment, home appliances, etc., and electrical signals transmitted therewith have been increased in speed and frequency. In general, a shielded electric wire made of a coaxial cable is used to transmit such a high-frequency electric signal. However, as the electric signal transmitted becomes higher in frequency, the shield connector connected to the shielded electric wire also has a high frequency. There is a growing demand for improved properties.

従来、このようなシールド電線の端末接続構造としては例えば図７に示すようなものが知られている。シールド電線１０は、金属製の複数の素線を撚り束ねた信号導体１２を、絶縁体１４を介して、同じく複数の素線を編んだ編組線１６よりなるシールド導体が被覆され、更にその外周を絶縁性のシース１８が覆った同軸の構造になっており、シールド導体１６が信号導体１２の外周を一定の間隔を置いて隙間なく覆うことで高周波の電気信号の伝送に適した構造になっている。   Conventionally, for example, a terminal connection structure of such a shielded wire as shown in FIG. 7 is known. The shielded electric wire 10 is covered with a shield conductor made of a braided wire 16 in which a plurality of strands made of metal are twisted and bundled and an insulator 14 is used to braid a plurality of strands. The shield conductor 16 covers the outer periphery of the signal conductor 12 at a constant interval and without gaps, so that a structure suitable for transmission of high-frequency electrical signals is obtained. ing.

このシールド電線１０の端末に接続されるシールドコネクタ１０ａは、シールド電線１０の信号導体１２と接続される図示しない内導体端子２０ａを、所定の誘電率を有する誘電体４０を介して外導体端子５０ａの筒状収容部５２で覆って電磁的にシールドする構造になっている。   The shield connector 10a connected to the end of the shielded electric wire 10 connects an inner conductor terminal 20a (not shown) connected to the signal conductor 12 of the shielded electric wire 10 to an outer conductor terminal 50a via a dielectric 40 having a predetermined dielectric constant. The cylindrical housing portion 52 is used to shield electromagnetically.

この内導体端子２０ａは導電性の金属板を屈曲形成して雄又は雌端子状に形成されており、先端から相手方の雌又は雄端子と嵌合するように嵌合部が形成されており、そしてこの後端に設けられた信号導体圧着部により、シールド電線１０の信号導体１２に接続されている。   This inner conductor terminal 20a is formed into a male or female terminal shape by bending a conductive metal plate, and a fitting portion is formed so as to be fitted to the other female or male terminal from the tip, The signal conductor 12 is connected to the signal conductor 12 of the shielded electric wire 10 by a signal conductor crimping portion provided at the rear end.

一方、外導体端子５０ａは、筒状収容部５２とシールド導体圧着部５４、シース圧着５６からなり、前後に開口した略円筒状に形成されている。内導体端子２０ａを誘電体４０を介して覆ってシールドするための筒状収容部５２はコネクタハウジングに挿入されるその先端から後端までほぼ一定の外径に形成されており、この外導体端子５０ａは、その筒状収容部５２の後端に形成されたシールド導体圧着部５４でシールド電線１０のシールド導体１６を挟着し、その更に後端に形成されたシース圧着部５６でシールド電線１０のシース１８を挟着して、シールド電線１０に接続されている。   On the other hand, the outer conductor terminal 50a is composed of a cylindrical housing portion 52, a shield conductor crimping portion 54, and a sheath crimping portion 56, and is formed in a substantially cylindrical shape that is open at the front and rear. A cylindrical housing portion 52 for covering and shielding the inner conductor terminal 20a via the dielectric 40 is formed to have a substantially constant outer diameter from the front end to the rear end inserted into the connector housing. Reference numeral 50a denotes a shield conductor crimping portion 54 formed at the rear end of the cylindrical housing portion 52 to sandwich the shield conductor 16 of the shielded electric wire 10 and a sheath crimping portion 56 formed at the rear end thereof to shield the shielded electric wire 10. The sheath 18 is sandwiched and connected to the shielded electric wire 10.

この外導体端子５２ａの筒状収容部５２の先端には、軸方向に延びるスリット６２が切欠き形成され、円周方向に広がる弾性接触片６４が形成されている。さらに、その弾性接触片６４の先端には径方向に張り出した膨出部６６が、相手側シールドコネクタの外導体端子と接触可能に設けられている。   A slit 62 extending in the axial direction is cut out at the tip of the cylindrical housing portion 52 of the outer conductor terminal 52a, and an elastic contact piece 64 extending in the circumferential direction is formed. Further, a bulging portion 66 projecting in the radial direction is provided at the tip of the elastic contact piece 64 so as to be in contact with the outer conductor terminal of the mating shield connector.

図７に示されたシールドコネクタ１０ａが相手側シールドコネクタ１０ｂと嵌合した状態のＤ−Ｄ断面図を図８（ａ）に、そしてそのＥ−Ｅ断面を図８（ｂ）に示す。前記外導体端子５０ａの弾性接触片６４が形成された収容筒部５２先端が、相手側コネクタ１０ｂの外導体端子の筒状収容部先端６０ｂに挿入されて接触接続されて、同じく嵌合接続されている内導体端子２０ａ，２０ｂを隙間なく覆っている。   FIG. 8 (a) shows a DD cross-sectional view of the shield connector 10a shown in FIG. 7 fitted to the mating shield connector 10b, and FIG. 8 (b) shows its EE cross-section. The distal end of the accommodating cylinder portion 52 in which the elastic contact piece 64 of the outer conductor terminal 50a is formed is inserted into the cylindrical accommodating portion distal end 60b of the outer conductor terminal of the mating connector 10b to be contact-connected and similarly fitted and connected. The inner conductor terminals 20a and 20b are covered without a gap.

この時、外導体端子５０ａの筒状収容部５２の先端に形成されて、径方向に張り出した膨出部６６の外径が、相手側の外導体端子５０ｂの筒状収容部先端６０ｂの内径より僅かに大きく形成されている。   At this time, the outer diameter of the bulging portion 66 formed at the distal end of the cylindrical housing portion 52 of the outer conductor terminal 50a and projecting in the radial direction is the inner diameter of the distal end of the cylindrical housing portion 60b of the counterpart outer conductor terminal 50b. It is formed slightly larger.

さらに、前記外導体端子５０ａの筒状収容部５２内に収容される誘電体４０は、軸方向にほぼ一定の外径をもった略円筒に形成されているが、前記外導体端子の弾性接触片５２ｂに覆われた部分には、前記弾性接触片５２ｂの内側方向への変位を許容するために僅かに細い小径部４２が形成されている。そして前記外導体端子５０ａの筒状収容部５２の先端よりわずかに突出して、その筒状収容部５２内に収容されている。   Further, the dielectric 40 accommodated in the cylindrical accommodating portion 52 of the outer conductor terminal 50a is formed in a substantially cylindrical shape having a substantially constant outer diameter in the axial direction. In the portion covered with the piece 52b, a slightly thin small-diameter portion 42 is formed to allow displacement of the elastic contact piece 52b in the inner direction. Then, the outer conductor terminal 50 a slightly protrudes from the tip of the cylindrical housing portion 52 and is accommodated in the cylindrical housing portion 52.

そしてシールドコネクタ１０ａ，１０ｂが嵌合した際には、外導体端子５０ａの筒状収容部５２の弾性接触片６４先端に形成された膨出部６６を相手側外導体端子５０ｂの筒状収容部先端６０ｂの内壁によって、僅かに内側に押さえつけて弾性変形させつつ接触させることで、この弾性接触片６４の反発力によって、良好な電気的接続を得ている。   When the shield connectors 10a and 10b are fitted, the bulging portion 66 formed at the tip of the elastic contact piece 64 of the cylindrical housing portion 52 of the outer conductor terminal 50a is used as the cylindrical housing portion of the counterpart outer conductor terminal 50b. A favorable electrical connection is obtained by the repulsive force of the elastic contact piece 64 by making the contact with the inner wall of the tip 60b while being slightly pressed and elastically deformed.

このようなシールドコネクタの例としては、特許文献１に記載されたシールドコネクタ等が知られている。   As an example of such a shield connector, a shield connector described in Patent Document 1 is known.

特開２０００−１１３９４６号公報JP 2000-1113946 A

しかし、このようなシールドコネクタ１０ａの先端部は、外導体端子５０ａの筒状収容部５２の弾性接触片６４の先端と筒状収容部５２に収容されている誘電体４０の先端との間に生じる隙間が保護されておらず剥き出しになった構造となっているので、外部からの衝撃等により破壊されやすいという問題がある。   However, the tip portion of the shield connector 10 a is between the tip of the elastic contact piece 64 of the cylindrical housing portion 52 of the outer conductor terminal 50 a and the tip of the dielectric 40 accommodated in the cylindrical housing portion 52. Since the generated gap is not protected and is exposed, there is a problem that it is easily broken by an external impact or the like.

例えば、シールドコネクタの１０ａのシールド電線１０への接続作業時に、外導体端子５０ａの筒状収容部５２の先端と誘電体４０先端との間の隙間に異物が入り込んで弾性接触片６４が捲れ上がり、押し曲げられて変形してしまうことがある。また、このシールドコネクタ１０ａを絶縁性の樹脂よりなるコネクタハウジング７０に挿入する際には（図９）、外導体端子５０ａ先端の膨出部６６がコネクタハウジング７０のキャビティ７２の内径より張り出しているので、外導体端子の弾性接触片６４を弾性変形させつつ挿入しなければならないため、大きな挿入力が必要となるだけでなく、この弾性接触片６４に過大な力が掛かりすぎて変形してしまうこともある。また、図１０に示すように、相手側シールドコネクタ１０ｂとの嵌合作業時に、シールドコネクタ１０ａ，１０ｂが軸方向にずれて嵌合しようとした場合、誘電体４０先端の外周端縁と外導体端子５０ａの弾性接触片６４の先端との間にある隙間に、相手側の外導体端子先端６０ｂが引っかかって正しく嵌合されないというような問題も生じる。   For example, when the shield connector 10a is connected to the shielded electric wire 10, a foreign object enters a gap between the tip of the cylindrical housing portion 52 of the outer conductor terminal 50a and the tip of the dielectric 40, and the elastic contact piece 64 is rolled up. , May be deformed by being pushed and bent. When the shield connector 10a is inserted into the connector housing 70 made of an insulating resin (FIG. 9), the bulging portion 66 at the tip of the outer conductor terminal 50a protrudes from the inner diameter of the cavity 72 of the connector housing 70. Therefore, since the elastic contact piece 64 of the outer conductor terminal has to be inserted while being elastically deformed, not only a large insertion force is required but also the elastic contact piece 64 is deformed due to excessive force. Sometimes. Further, as shown in FIG. 10, when the shield connectors 10a and 10b are shifted in the axial direction during the fitting operation with the mating shield connector 10b, the outer peripheral edge of the tip of the dielectric 40 and the outer conductor There is also a problem that the mating outer conductor terminal tip 60b is caught in the gap between the terminal 50a and the tip of the elastic contact piece 64 and is not properly fitted.

そこで本発明の目的は、シールド電線の端末部に取り付けられる外導体端子の先端部分を保護し、その変形と、これによる相手側シールドコネクタとの嵌合不良を防止して、良好な電気的接続を得ることができ、さらに小型化を可能にするシールドコネクタを提供することにある。   Therefore, an object of the present invention is to protect the tip portion of the outer conductor terminal attached to the terminal portion of the shielded electric wire, prevent its deformation and poor fitting with the mating shield connector by this, and make a good electrical connection It is another object of the present invention to provide a shielded connector that can be further downsized.

上記課題を解決するために、本発明の請求項１に係るシールドコネクタは、シールド電線の信号導体の端末に内導体端子が接続され、この内導体端子が誘電体を介して外導体端子の筒状収容部に収容されると共に、この外導体端子がシールド電線の前記シールド導体に接続されてコネクタハウジングに挿入されてなるシールドコネクタにおいて、前記外導体端子の筒状収容部の前記コネクタハウジングへの挿入先端部位に、そのシールド電線の径方向に弾性変形可能な弾性接触片が周方向複数形成され、この外導体端子の筒状収容部内に収容される誘電体の前記コネクタハウジングへの挿入方向先端外周縁には前記弾性接触片を保護する張り出し部が径方向に形成されてなることを要旨とするものである。   In order to solve the above-mentioned problem, the shield connector according to claim 1 of the present invention is such that the inner conductor terminal is connected to the end of the signal conductor of the shielded wire, and the inner conductor terminal is a cylinder of the outer conductor terminal via a dielectric. In the shield connector in which the outer conductor terminal is connected to the shield conductor of the shielded electric wire and inserted into the connector housing, the cylindrical conductor of the outer conductor terminal is connected to the connector housing. A plurality of elastic contact pieces that are elastically deformable in the radial direction of the shielded electric wire are formed in the insertion tip portion in the circumferential direction, and the dielectric material accommodated in the cylindrical housing portion of the outer conductor terminal is inserted in the connector housing in the insertion direction. The gist of the invention is that the outer peripheral edge is formed with a projecting portion for protecting the elastic contact piece in the radial direction.

また、本発明の請求項２記載のシールドコネクタは、請求項１記載のシールドコネクタにおいて、前記外導体端子の筒状収容部に収容される前記誘電体の張り出し部の前記コネクタハウジングへの挿入方向先端外周縁には、前記コネクタハウジングに挿入される相手側コネクタ端子との嵌合の際の相手側コネクタ端子の外導体端子先端部がシールド電線の径方向所定位置に誘導されるようテーパ状又はＲ状に面取り形成されていることを要旨とするものである。   The shield connector according to claim 2 of the present invention is the shield connector according to claim 1, wherein the protruding portion of the dielectric housed in the cylindrical housing portion of the outer conductor terminal is inserted into the connector housing. The outer peripheral edge of the tip is tapered so that the outer conductor terminal tip of the mating connector terminal when being mated with the mating connector terminal inserted into the connector housing is guided to a predetermined radial position of the shielded electric wire. The gist is that it is chamfered in an R shape.

また、本発明の請求項３記載のシールドコネクタは、請求項１および請求項２記載のシールドコネクタにおいて、前記外導体端子の筒状収容部の途中部位からコネクタハウジング挿入方向先端部位にかけて小径筒状に形成され、その先端部位に前記弾性接触片が形成されていることを要旨とするものである。   The shield connector according to claim 3 of the present invention is the shield connector according to claim 1 or 2, wherein the shield connector has a small-diameter cylindrical shape extending from a middle portion of the tubular housing portion of the outer conductor terminal to a tip portion in the connector housing insertion direction. And the elastic contact piece is formed at the tip portion thereof.

また、本発明の請求項４記載のシールドコネクタは、請求項１乃至請求項３記載のシールドコネクタにおいて、前記外導体端子の筒状収容部の前記小径筒状部に部分的に開口部を形成し、該開口部を介して前記誘電体が露呈されていることを要旨とするものである。   The shield connector according to claim 4 of the present invention is the shield connector according to claims 1 to 3, wherein an opening is partially formed in the small-diameter cylindrical portion of the cylindrical accommodating portion of the outer conductor terminal. However, the gist is that the dielectric is exposed through the opening.

上記請求項１に記載されるシールドコネクタの保護構造によれば、前記外導体端子の筒状収容部に収容される誘電体の先端に前記外導体端子の弾性接触片を保護する張り出し部が形成されているので、外導体端子の先端に異物が衝突しても弾性接触片が変形するのを防ぐことができる。また、この張り出し部の外径を調節することにより、前記外導体端子の弾性接触片の、その弾性限界を超えた内側への無理な変位を防止することも可能になる。   According to the shield connector protection structure described in claim 1, the overhanging portion that protects the elastic contact piece of the outer conductor terminal is formed at the tip of the dielectric housed in the cylindrical housing portion of the outer conductor terminal. Therefore, even if a foreign object collides with the tip of the outer conductor terminal, the elastic contact piece can be prevented from being deformed. Further, by adjusting the outer diameter of the protruding portion, it is possible to prevent the elastic contact piece of the outer conductor terminal from being forcibly displaced inward beyond its elastic limit.

また、請求項２に記載の発明によれば、前記誘電体の張り出し部の先端外周縁がテーパ面に形成されているので、相手側シールドコネクタとの嵌合時に、これらのシールドコネクタの嵌合突き合わせ面同士が軸方向に微小なずれをもって当接した場合でも、相手側シールドコネクタの外導体端子先端をこのテーパ面に沿って滑らせて移動することで、相手側シールドコネクタを正しい嵌合位置に誘導して嵌合させることが可能となる。   According to the second aspect of the present invention, since the outer peripheral edge of the tip of the dielectric overhanging portion is formed in a tapered surface, when the mating shield connector is fitted, these shield connectors are fitted. Even when the abutting surfaces are in contact with each other with a slight deviation in the axial direction, the mating shield connector can be properly fitted by sliding the outer conductor terminal tip of the mating shield connector along this tapered surface. It is possible to guide and fit them.

また、請求項３に記載の発明のように、前記外導体端子先端に小径部を形成することにより、この外導体端子をコネクタハウジングに挿入する際の挿入抵抗を低減させることができ、スムーズな組付けを可能とし、組み付け作業性が向上する。また、過大な力を加えて外導体端子をコネクタハウジングに無理に挿入することによる外導体端子の変形、破損を防ぐことができる。また、相手側シールドコネクタの外導体端子との嵌合部分の外径も小さくすることができ、シールドコネクタの小型化が可能となる。   Further, as in the invention described in claim 3, by forming a small diameter portion at the tip of the outer conductor terminal, the insertion resistance when the outer conductor terminal is inserted into the connector housing can be reduced, and smooth. Assembly is possible and assembly workability is improved. Further, it is possible to prevent deformation and breakage of the outer conductor terminal due to excessive force applied to forcefully inserting the outer conductor terminal into the connector housing. Further, the outer diameter of the fitting portion of the mating shield connector with the outer conductor terminal can be reduced, and the shield connector can be reduced in size.

請求項４に記載の発明によれば、前記筒状収容部先端の小径部に部分的に開口を形成することにより、インピーダンス整合を図ることができる。一般に、このように部分的に外導体端子の内径を小さく形成するとインピーダンスの低下が起きるが、この小径部に部分的に開口を形成することにより、空気層を介在させることになり、インピーダンスの低下を防いで、インピーダンス整合を図ることが可能となる。   According to the invention described in claim 4, impedance matching can be achieved by forming an opening partially in the small diameter portion at the tip of the cylindrical housing portion. Generally, if the inner diameter of the outer conductor terminal is partially reduced in this way, the impedance is lowered. However, by partially forming an opening in the small diameter portion, an air layer is interposed and the impedance is lowered. Thus, impedance matching can be achieved.

請求項５に記載のシールドコネクタによれば、前記請求項１乃至請求項４記載のシールドコネクタ外導体端子の保護構造を有しているので、外導体端子先端部に形成された弾性接触片の変形による破損を防ぎ、相手側シールドコネクタとの嵌合作業性が良く、また良好な電気的接続が可能となる。また、コネクタハウジングへの組み付け作業性も良く、更に小型化が可能で、インピーダンス整合を図ることもできるため、良好な高周波特性を得ることも可能となる。   According to the shield connector of the fifth aspect, since the shield connector outer conductor terminal protection structure according to the first to fourth aspects is provided, the elastic contact piece formed at the front end portion of the outer conductor terminal is provided. Breakage due to deformation is prevented, the workability with the mating shield connector is good, and good electrical connection is possible. In addition, the workability of assembling to the connector housing is good, further miniaturization is possible, and impedance matching can be achieved, so that it is possible to obtain good high frequency characteristics.

At the rear end, a signal conductor connecting portion 124 for crimping and connecting the signal conductor 12 of the shielded electric wire 10 is provided. In the shielded electric wire 10, the sheath 18 and the insulator 14 are peeled to a predetermined length, the signal conductor 12 and the shield conductor 16 are exposed, and the signal conductor connection portion 124 of the inner conductor terminal 120 is connected to the tip of the signal conductor 12.

Thus, an elastic contact piece 164 that is elastically deformable in the radial direction is formed. Further, a bulging portion 66 projecting in the radial direction is provided at the tip of the elastic contact piece 164 so as to be in contact with the outer conductor terminal of the mating shield connector.

誘電体１４０は、絶縁性の樹脂からなり、前記内導体端子１２０を収容する内導体端子収容孔１４９を有する略円筒状に形成されている。この誘電体１４０の後端部１４８は前記外導体端子１５０の筒状収容部１５２の内径とほぼ同じ外径に形成されており、誘電体１４０の先端部１４６は、前記外導体端子１５０の小径部１６０に形成される弾性接触片の内側方向への変位を許容する空間を設けるために、外導体端子の小径部１６０の内径よりも若干小さくその外径が形成されている。そしてこの先端部の端縁には、径方向に張り出した張り出し部１４２が設けられており、この先端外周端縁は面取りされてテーパ面１４４に形成されている。   The dielectric 140 is made of an insulating resin and is formed in a substantially cylindrical shape having an inner conductor terminal accommodation hole 149 that accommodates the inner conductor terminal 120. The rear end portion 148 of the dielectric 140 is formed to have an outer diameter substantially the same as the inner diameter of the cylindrical housing portion 152 of the outer conductor terminal 150, and the front end portion 146 of the dielectric 140 is a small diameter of the outer conductor terminal 150. In order to provide a space that allows displacement of the elastic contact piece formed in the portion 160 in the inner direction, the outer diameter is slightly smaller than the inner diameter of the small-diameter portion 160 of the outer conductor terminal. A projecting portion 142 projecting in the radial direction is provided at the end edge of the front end portion, and the outer peripheral end edge of the front end is chamfered to form a tapered surface 144.

この誘電体１４０を前記外導体端子１５０の筒状収容部１５２に後方から挿入する際は、誘電体１４０の先端に形成された張り出し部１４２が、外導体端子１５０の小径部１６０に形成された弾性接触片１６４を外側に押し広げて通過し、この張り出し部１４２が小径部１６０の先端から突出する位置まで差し込まれると、前記押し広げられた弾性接触片１６４はその弾性により元の位置に復元する。   When the dielectric 140 is inserted into the cylindrical housing portion 152 of the outer conductor terminal 150 from behind, an overhang 142 formed at the tip of the dielectric 140 is formed in the small diameter portion 160 of the outer conductor terminal 150. When the elastic contact piece 164 is pushed outward and passes and the protruding portion 142 is inserted to a position where it protrudes from the tip of the small diameter portion 160, the elastic contact piece 164 thus expanded is restored to its original position due to its elasticity. To do.

このようにして外導体端子１５０に収容された誘電体１４０の内導体端子収容孔１４９にシールド電線１０の信号導体１２が接続された内導体端子１２０を挿入する。その後シールド電線１０のシールド導体１６を外導体端子１５０のシールド導体圧着部５４でかしめて接続固定し、シース１８をシース圧着部５６でかしめて機械的固着力を補強する。   In this way, the inner conductor terminal 120 to which the signal conductor 12 of the shielded electric wire 10 is connected is inserted into the inner conductor terminal accommodating hole 149 of the dielectric 140 accommodated in the outer conductor terminal 150. Thereafter, the shield conductor 16 of the shielded electric wire 10 is caulked and fixed by the shield conductor crimping portion 54 of the outer conductor terminal 150, and the sheath 18 is caulked by the sheath crimping portion 56 to reinforce the mechanical fixing force.

図２に示すように、本実施例のシールドコネクタ１００は外導体端子１５０の先端に形成された弾性接触片１６４が、誘電体１４０の張り出し部１４２に保護されているので、このシールドコネクタ１００のシールド電線１０への接続作業等の間に異物等に接触して、弾性接触片１６４が引っかかって破損する心配がない。   As shown in FIG. 2, in the shield connector 100 of this embodiment, the elastic contact piece 164 formed at the tip of the outer conductor terminal 150 is protected by the protruding portion 142 of the dielectric 140. There is no fear that the elastic contact piece 164 is caught and damaged by contact with a foreign object or the like during the connection work to the shielded electric wire 10 or the like.

図３は、図２に示されるシールドコネクタ１００に相手側シールドコネクタ２００が嵌合される際の様子をＡ−Ａ断面矢視図で示したものである。相手側シールドコネクタ２００も前記シールドコネクタ１００と同様に、外導体端子２５０、誘電体４０及び内導体端子２２０からなり、内導体端子２２０にはシールド電線１０の信号導体１２が、外導体端子２５０にはシールド電線１０のシールド導体が接続されている。前記シールドコネクタ１００の内導体端子１２０と、相手側のシールドコネクタ２００の内導体端子２２０が互いに嵌合接続して電気信号を伝達し、更にこれら内導体端子１２０，２２０を誘電体１４０，２４０を介して覆う外導体端子１５０，２５０が同じく互いに嵌合接続して内導体端子１２０，２２０を電磁的にシールドするものである。   FIG. 3 shows a state when the mating shield connector 200 is fitted to the shield connector 100 shown in FIG. Similarly to the shield connector 100, the counterpart shield connector 200 includes an outer conductor terminal 250, a dielectric 40, and an inner conductor terminal 220. The signal conductor 12 of the shielded electric wire 10 is connected to the outer conductor terminal 250 at the inner conductor terminal 220. Is connected to the shield conductor of the shielded electric wire 10. The inner conductor terminal 120 of the shield connector 100 and the inner conductor terminal 220 of the counterpart shield connector 200 are fitted and connected to each other to transmit an electric signal. The inner conductor terminals 120 and 220 are further connected to the dielectrics 140 and 240. The outer conductor terminals 150 and 250 covering the inner conductor terminals are also fitted and connected to each other to shield the inner conductor terminals 120 and 220 electromagnetically.

これらシールドコネクタ１００，２００の嵌合時には、それぞれが同一線上に対向して配置されて、互いに接近して一方の外導体端子に他方の外導体端子が挿入されて嵌合するのが望ましいが、特にコネクタの小型化が進むと、部品間の押さえ代が減少して、がたつき等が生じ、ずれの無い状態で外導体端子１５０，２５０を配置するのが困難になる。このようなときには、図３に示すように、前記外導体端子１５０と相手側の外導体端子２５０の先端が軸方向にずれた状態で配置される場合が生じやすくなる。   When the shield connectors 100 and 200 are fitted, it is desirable that they are arranged opposite to each other on the same line, and close to each other and the other outer conductor terminal is inserted into the other outer conductor terminal. In particular, when the size of the connector is further reduced, the press margin between components is reduced, rattling or the like occurs, and it becomes difficult to dispose the outer conductor terminals 150 and 250 without any deviation. In such a case, as shown in FIG. 3, the outer conductor terminal 150 and the counterpart outer conductor terminal 250 are likely to be disposed in a state where the tips of the outer conductor terminal 250 are shifted in the axial direction.

このような場合においても、本実施例のように、外導体端子１５０の筒状収容部１５２内に収容された誘電体１４０の先端の張り出し部１４４は、外導体端子１５０の筒状収容部１５２の先端端縁よりも突出して軸方向に張り出しているので、相手側コネクタとの嵌合突き合わせ面が前記誘電体１４０の張り出し部１４４で覆われており、相手側外導体端子と引っかかる部分が無く、外導体端子１５０の先端が保護される。   Even in such a case, as in the present embodiment, the protruding portion 144 at the tip of the dielectric 140 accommodated in the cylindrical accommodating portion 152 of the outer conductor terminal 150 is the cylindrical accommodating portion 152 of the outer conductor terminal 150. Since the protrusion protrudes beyond the end edge of the connector and protrudes in the axial direction, the mating butting surface with the mating connector is covered with the projecting portion 144 of the dielectric 140, and there is no portion caught by the mating outer conductor terminal. The tip of the outer conductor terminal 150 is protected.

そして、この張り出し部１４２の外周端縁は面取りされてテーパ面１４４に形成されているので、図３のように、外導体端子１５０，２５０が軸方向にずれて嵌合を開始した場合でも、相手側外導体端子２５０の先端２６０をこのテーパ面１４４に沿って滑らせて、正しい嵌合位置に誘導することができるので、嵌合作業性がよい。   And since the outer periphery edge of this overhang | projection part 142 is chamfered and formed in the taper surface 144, as shown in FIG. 3, even when the outer conductor terminals 150 and 250 start to fit in the axial direction, Since the tip 260 of the counterpart outer conductor terminal 250 can be slid along the tapered surface 144 and guided to the correct fitting position, the fitting workability is good.

図４は、このシールドコネクタ１００を絶縁性の樹脂よりなるコネクタハウジング７０に挿入する様子を示した断面図である。このコネクタハウジングは、合成樹脂材料により略筒状に一体に形成されており、その内部にシールドコネクタ１００がコネクタ挿入口７４から挿入されて、コネクタ収容室７２に収容される。   FIG. 4 is a cross-sectional view showing how the shield connector 100 is inserted into a connector housing 70 made of an insulating resin. The connector housing is integrally formed of a synthetic resin material in a substantially cylindrical shape. The shield connector 100 is inserted into the connector housing from the connector insertion port 74 and is accommodated in the connector accommodating chamber 72.

このコネクタハウジング７０の内径は、コネクタ挿入口７４ではシールドコネクタ１００のシールド導体圧着部５４およびシース圧着部５６の外径にほぼ等しく、コネクタ収容室７２ではシールドコネクタ１００の筒状収容部１５０の基端部分の外径にほぼ等しく形成されており、シールドコネクタ１００挿入後は図示しないリテーナやランス等により固定されて抜落が防止される。   The inner diameter of the connector housing 70 is substantially equal to the outer diameters of the shield conductor crimping portion 54 and the sheath crimping portion 56 of the shield connector 100 at the connector insertion port 74, and the base of the cylindrical housing portion 150 of the shield connector 100 in the connector housing chamber 72. It is formed substantially equal to the outer diameter of the end portion, and after the shield connector 100 is inserted, it is fixed by a retainer, a lance or the like (not shown) to prevent dropping.

従って、このシールドコネクタ１００は、その外導体端子１５０の先端に小径部１６０が設けられているため、この小径部１６０の外径がコネクタハウジング７０のコネクタ収容室７２の内壁に比べて十分小さく、弾性接触片１６４の先端に形成された膨出部１６６がコネクタ収容室７２の内壁に接触することなく、スムーズに挿入することができる。そのため、弾性接触片１６４のが変形して接触不良等を起こすことがない。   Therefore, since the shield connector 100 is provided with the small diameter portion 160 at the tip of the outer conductor terminal 150, the outer diameter of the small diameter portion 160 is sufficiently smaller than the inner wall of the connector housing chamber 72 of the connector housing 70. The bulging portion 166 formed at the tip of the elastic contact piece 164 can be smoothly inserted without contacting the inner wall of the connector housing chamber 72. Therefore, the elastic contact piece 164 is not deformed to cause a contact failure or the like.

図５は、本発明の第２の実施形態であるシールドコネクタ１００ａがシールド電線１０に接続された状態の斜視図である。この外導体端子１５０ａは前記第１の実施形態のシールドコネクタ１００と同じく、外導体端子１５０ａの筒状収容部１５２先端部分には小径部１６０が形成されており、弾性接触片１６４が形成されている。そして、誘電体１４０の先端部分は前記弾性接触片１６４より軸方向に突出して径方向に張り出した張り出し部１４２を備えており、前記弾性接触片１６４を保護している。   FIG. 5 is a perspective view showing a state in which the shield connector 100a according to the second embodiment of the present invention is connected to the shielded electric wire 10. As with the shield connector 100 of the first embodiment, the outer conductor terminal 150a is formed with a small-diameter portion 160 at the distal end portion of the cylindrical housing portion 152 of the outer conductor terminal 150a, and an elastic contact piece 164 is formed. Yes. The distal end portion of the dielectric 140 includes an overhanging portion 142 that protrudes in the axial direction from the elastic contact piece 164 and projects in the radial direction, and protects the elastic contact piece 164.

そして、このシールドコネクタ１００ａの外導体端子１５０ａは、前記弾性接触片１６４に部分的に開口部１６８が形成され、筒状収容部１５２に収容された誘電体１４０が露呈した状態となっている。   The outer conductor terminal 150a of the shield connector 100a is in a state where an opening 168 is partially formed in the elastic contact piece 164 and the dielectric 140 accommodated in the cylindrical accommodating portion 152 is exposed.

この図５に示されるシールドコネクタ１００ａが相手側シールドコネクタ２００と嵌合接続した状態のＢ−Ｂ断面図を図６（ａ）に、そのＣ−Ｃ断面図を図６（ｂ）に示す。シールド電線１０の信号導体１２に接続されたシールドコネクタ１００ａの内導体端子１２０と別のシールド電線１０の信号導体１２に接続されたシールドコネクタ２００の内導体端子２２０は互いに嵌合接続して電気信号を伝達し、シールド電線１０のシールド導体１６に接続された外導体端子１５０ａ，２５０も互いに嵌合接続して、これら内導体端子１２０，２２０を誘電体１４０，２４０を介して覆って電磁的にシールドしている。   FIG. 6A is a sectional view taken along the line B-B in a state where the shield connector 100a shown in FIG. 5 is fitted and connected to the mating shield connector 200, and FIG. 6B is a sectional view taken along the line C-C. The inner conductor terminal 120 of the shield connector 100a connected to the signal conductor 12 of the shielded electric wire 10 and the inner conductor terminal 220 of the shield connector 200 connected to the signal conductor 12 of another shielded electric wire 10 are fitted and connected to each other. The outer conductor terminals 150a and 250 connected to the shield conductor 16 of the shielded electric wire 10 are also fitted and connected to each other, and the inner conductor terminals 120 and 220 are covered with the dielectrics 140 and 240 to electromagnetically. Shielded.

この相手側シールドコネクタ２００の外導体端子２５０の筒状収容部２５２は、シールドコネクタ１００ａの外導体端子１５０の小径部１６０の外径とほぼ等しい内径に形成されている。そして、シールドコネクタ１００ａの外導体端子１５０ａ先端の小径部１６０が、相手側外導体端子２５０の筒状収容部先端２６０に挿入されて、前記小径部１６０に形成された弾性接触片１６４先端の膨出部１６６が、相手側外導体端子２５０の筒状収容部２５２の内壁に押されて弾性変形し、その反発力によって相手側外導体端子２００の筒状収容部先端２６０の内壁と安定して接続される。従って、シールドコネクタ１００ａの外導体端子１５０ａはその先端が小径に形成されているので、相手側外導体端子２００の筒状収容部２５２もこれに合わせて従来より径を細く形成することができるので、コネクタを小型化することができる。   The cylindrical housing portion 252 of the outer conductor terminal 250 of the mating shield connector 200 is formed to have an inner diameter substantially equal to the outer diameter of the small diameter portion 160 of the outer conductor terminal 150 of the shield connector 100a. The small-diameter portion 160 at the tip of the outer conductor terminal 150a of the shield connector 100a is inserted into the cylindrical housing portion tip 260 of the counterpart outer conductor terminal 250, and the tip of the elastic contact piece 164 formed in the small-diameter portion 160 is expanded. The protruding portion 166 is pushed and elastically deformed by the inner wall of the cylindrical housing portion 252 of the mating outer conductor terminal 250, and the repulsive force stably stabilizes the inner wall of the distal end 260 of the mating outer conductor terminal 200. Connected. Therefore, since the outer conductor terminal 150a of the shield connector 100a has a small diameter at the tip, the cylindrical housing portion 252 of the counterpart outer conductor terminal 200 can be formed with a smaller diameter than the conventional one. The connector can be miniaturized.

しかし、この外導体端子１５０ａの小径部１５２では、この部分でだけ外導体端子１５０ａの内径が小さくなっているため、インピーダンスが低下してしまう。そこで、外導体端子１５０ａの先端の弾性接触片１６４に部分的に開口部１６８に形成することにより、内導体端子１２０と相手側外導体端子２５０との間で、誘電体１４０の外周部分に部分的に空気層を介在させて、インピーダンスの低下を抑え、インピーダンス整合を図ることができる。この開口部１６８の大きさは、所定のインピーダンスになるように適宜調節することができる。また、この開口部１６８に部分的に誘電体１４０を張り出させて空気層の厚さを調節してインピーダンスを所定の値に調整することも可能である。   However, in the small diameter portion 152 of the outer conductor terminal 150a, since the inner diameter of the outer conductor terminal 150a is small only in this portion, the impedance is lowered. Therefore, the elastic contact piece 164 at the tip of the outer conductor terminal 150a is partially formed in the opening 168, so that a portion of the outer periphery of the dielectric 140 is partially formed between the inner conductor terminal 120 and the counterpart outer conductor terminal 250. In addition, it is possible to achieve impedance matching by suppressing the decrease in impedance by interposing an air layer. The size of the opening 168 can be appropriately adjusted so as to have a predetermined impedance. It is also possible to adjust the impedance to a predetermined value by partially extending the dielectric 140 in the opening 168 and adjusting the thickness of the air layer.

以上説明したように、本発明に係るシールドコネクタ及びその外導体端子の保護構造によれば、シールドコネクタの組み付け時、及び嵌合時等において、外導体端子の先端に形成された弾性接触片を保護することが可能となり、その変形を防止し、更に相手側シールドコネクタとの嵌合作業性向上することができ、良好な電気的接続を得ることが可能となる。さらに、シールドコネクタを小型化することができるだけでなく、コネクタ全体として精度良くインピーダンス整合されたものとすることができ、良好な高周波特性を得ることが可能となる。   As described above, according to the shield connector and the protection structure for the outer conductor terminal according to the present invention, the elastic contact piece formed at the front end of the outer conductor terminal at the time of assembling and fitting the shield connector is provided. It becomes possible to protect, prevent the deformation, further improve the fitting workability with the counterpart shield connector, and obtain a good electrical connection. Furthermore, not only can the shield connector be downsized, but also the entire connector can be impedance-matched with high accuracy, and good high frequency characteristics can be obtained.

In the first and second embodiments, the bulging portion for contacting the mating outer conductor terminal is provided at the tip of the elastic contact piece of the outer conductor terminal. It can also be provided.

また、前記第１および第２の実施形態は、雌型の内導体端子と雄型の外導体端子の組み合わせの例で示したが、内導体端子、外導体端子およびコネクタハウジングの雌雄の組み合わせは、その用途に応じて種々の組み合わせが可能である。   In the first and second embodiments, the example of the combination of the female inner conductor terminal and the male outer conductor terminal is shown. However, the combination of the male and female of the inner conductor terminal, the outer conductor terminal and the connector housing is as follows. Various combinations are possible depending on the application.

また、シールド電線のシールド導体と絶縁体の間に挿入されるスリーブを備えたものや、嵌合部が角型のシールドコネクタにも適用可能なのは言うまでもない。   Needless to say, the present invention can also be applied to a shield connector having a sleeve inserted between a shield conductor of a shielded wire and an insulator, or a shield connector having a square fitting portion.

本発明に係るシールドコネクタは、外導体端子の変形が防止され、接続信頼性があり、更にインピーダンス整合が図られて高周波信号の伝送に適しているので、例えば、自動車用ワイヤハーネスのコネクタ部材およびその製造等に好適に利用することができる。   Since the shield connector according to the present invention prevents deformation of the outer conductor terminal, has connection reliability, and is further suitable for transmission of high-frequency signals by impedance matching, for example, a connector member for an automobile wire harness and It can utilize suitably for the manufacture etc.
