Description

本発明は、シールド電気コネクタに関する。 The present invention relates to a shielded electrical connector.

シールド電気コネクタとしては、相手コネクタとの挿抜方向を軸線方向として配された端子を上記軸線まわりで包囲する金属板製の筒状体部を有するシールドケースを備えている電気コネクタ（以下「コネクタ」）が知られている。 The shielded electrical connector is an electrical connector having a shield case having a tubular body made of a metal plate that surrounds terminals arranged with the mating connector in the axial direction (hereinafter referred to as "connector"). )It has been known.

この種のコネクタは、例えば、特許文献１に開示されている。特許文献１では、コネクタ（特許文献１ではマイクロ・プラグ１´）はハウジング（特許文献１では、図中符号なし）により配列保持された端子（接点ピン１３ａ〜１３ｅ）を略角筒型の筒状体部をもつシールドケース（シールド１０´）が包囲している。このシールドケース（シールド１０´）は、ほぼ同形の対応筒状体部をもつ相手コネクタ（マイクロ・レセプタクル２´）のシールドケース（シールド２０´）の上記対応筒状体部に挿入される。 This type of connector is disclosed in, for example, Patent Document 1. In Patent Document 1, the connector (micro plug 1'in Patent Document 1) has terminals (contact pins 13a to 13e) arranged and held by a housing (in Patent Document 1, no reference numerals in the drawings), and is a substantially square cylinder. A shield case (shield 10') having a shaped body portion surrounds the shield case (shield 10'). The shield case (shield 10') is inserted into the corresponding tubular body portion of the shield case (shield 20') of the mating connector (micro receptacle 2') having a corresponding tubular body portion having substantially the same shape.

上記コネクタのシールドケースには、その周方向の１箇所（図示の例では、端子配列方向となるコネクタ幅方向の中央位置）にキー溝部（凹部１７）として切欠きが軸線方向に延びて形成されており、相手コネクタのシールドケースの対応筒状体部に周方向で上記キー溝に対応する位置にキーとして設けられた突片（突出部２８）が上記キー溝に係合する。かくして、相手コネクタが同形の対応筒状体部のシールドケースを有していても、正規の相手方でなく異なる位置にキーとして突片が設けられている相手コネクタの嵌合を阻止している。 The shield case of the connector is formed with a notch extending in the axial direction as a keyway portion (recess 17) at one location in the circumferential direction (in the illustrated example, the central position in the connector width direction which is the terminal arrangement direction). A projecting piece (protruding portion 28) provided as a key at a position corresponding to the key groove in the circumferential direction on the corresponding tubular body portion of the shield case of the mating connector engages with the key groove. Thus, even if the mating connector has a shield case of a corresponding tubular body portion having the same shape, the mating of the mating connector in which the projecting piece is provided as a key at a different position than the regular counterparty is prevented.

上記コネクタのシールドケースは、１枚の金属板を周方向で屈曲して略角筒型の筒状体部を形成しており、上記キー溝の部分は１枚の金属板の部分が切り欠かれたままである。 In the shield case of the connector, one metal plate is bent in the circumferential direction to form a substantially square tubular body portion, and the key groove portion is cut out from the one metal plate portion. It remains struck.

特開２０１５−５１０２３７JP 2015-510237

特許文献１におけるコネクタにあっては、シールドケースはその筒状体部の全周が１枚の金属板のみで形成されていてその周方向１箇所に、キー溝が切欠きとして形成されている。したがって、このキー溝の部分は、シールドケースで部分的に切欠かかれたままである。 In the connector in Patent Document 1, the entire circumference of the tubular body portion of the shield case is formed of only one metal plate, and a key groove is formed as a notch at one location in the circumferential direction. .. Therefore, this portion of the keyway remains partially notched by the shield case.

かかる状態では、シールドケースは、キー溝の部分で、強度が低下する虞れがある。シールドケースは、一般に薄い金属板を筒状に屈曲形成することで、上記筒状体部を小型軽量ながらその強度を確保している。この筒状体部は、相手コネクタの対応部が嵌合・抜出される部分となるので、その際、比較的大きな力を受ける。特に相手コネクタが、こじりを伴ったり、傾いたまま嵌合・抜出されるときわめて大きな力が生じ、上記キー溝、特に溝隅部に応力集中をもたらし、シールドケースや端子等を有する嵌合部の破損・変形につながる。 In such a state, the strength of the shield case may decrease at the keyway portion. The shield case is generally formed by bending a thin metal plate into a tubular shape to ensure the strength of the tubular body portion while being compact and lightweight. Since the tubular body portion is a portion where the corresponding portion of the mating connector is fitted and pulled out, a relatively large force is received at that time. In particular, if the mating connector is fitted or pulled out while being twisted or tilted, an extremely large force is generated, causing stress concentration in the keyway, especially the groove corner, and the fitting part having a shield case, terminals, etc. It leads to damage and deformation of.

本発明は、かかる事情に鑑み、シールドケースの強度を低下させることなくキー溝を形成可能なシールドケースを有するシールド電気コネクタを提供することを課題とする。 In view of such circumstances, it is an object of the present invention to provide a shielded electrical connector having a shielded case capable of forming a key groove without lowering the strength of the shielded case.

本発明に係るシールド電気コネクタは、相手コネクタとの挿抜方向を軸線方向として、端子を上記軸線まわりで包囲する金属板製の筒状体部を有するシールドケースを備える。 The shielded electric connector according to the present invention includes a shield case having a tubular body portion made of a metal plate that surrounds the terminal around the axis with the insertion / extraction direction with the mating connector as the axis direction.

かかるシールド電気コネクタにおいて、本発明では、上記筒状体部は、相手コネクタ側に向く受入開口部の開口縁部における周方向の一部の範囲で折返されて上記筒状体部の外面の一部に重なって位置する外板部を有し、折返された領域内で上記軸線方向に延び上記開口縁部に開口して上記相手コネクタのキー部を受け入れる切欠状のキー溝部が少なくとも上記筒状体部に形成されている。 In such a shielded electric connector, in the present invention, the tubular body portion is folded back in a part of the circumferential direction at the opening edge portion of the receiving opening facing the mating connector side to be one of the outer surfaces of the tubular body portion. The notch-shaped keyway portion that has an outer plate portion that is positioned so as to overlap the portion, extends in the axial direction in the folded region, opens to the opening edge portion, and receives the key portion of the mating connector is at least tubular. It is formed on the body.

このような本発明では、シールドケースが少なくとも筒状体部の一部にキー溝部が形成され、シールドケースがその筒状体部の周方向での一部で折返しにより外板部が重なって位置し、その折返しにより筒状体と外板部との二枚重ね構造とすることで、キー溝部そして周辺の強度が向上する。 In such an invention, the shield case has a keyway portion formed at least in a part of the tubular body portion, and the shield case is located at a part of the tubular body portion in the circumferential direction where the outer plate portions overlap due to folding back. However, the strength of the keyway portion and its surroundings is improved by forming a double-layered structure of the tubular body and the outer plate portion by folding back.

By doing so, the lock groove portion is formed in the tubular main part by communicating with the key groove portion, and both the key groove portion and the lock groove portion can be compactly stored in a small area without being separated from each other, and the strength of the shield case can be obtained. The decrease can be suppressed.

本発明において、上記シールドケースは、上記外板部に上記筒状体部の上記ロック溝部と連通する孔部が形成され、該孔部が上記筒状本部の上記ロック溝部に連通していることが好ましい。かかる形態では、筒状体部と外板部とが重なっていることで、筒状体部のロック溝部と外板部の孔部が連通してロック溝部を板厚方向で実質的に拡張し、ロック溝部でのロック係止力を向上させる。 In the present invention, in the shield case, a hole portion communicating with the lock groove portion of the tubular body portion is formed in the outer plate portion, and the hole portion communicates with the lock groove portion of the tubular head portion. Is preferable. In such a form, since the tubular body portion and the outer plate portion overlap, the lock groove portion of the tubular body portion and the hole portion of the outer plate portion communicate with each other, and the lock groove portion is substantially expanded in the plate thickness direction. , Improves the lock locking force in the lock groove.

本発明において、上記折返基部は、上記外板部の折返し位置に上記キー溝部に連通する折返用溝部が形成され、該折返用溝部は、上記折返基部が延びる方向での上記キー溝部の幅範囲を含み該キー溝部よりも幅が広いようにすることができる。こうすることで、相手コネクタのキー部は折返用が折返基部に形成する開口に進入してからキー溝部へ導入されるので、導入が容易となる。 In the present invention, the folding base portion is formed with a folding groove portion communicating with the key groove portion at the folding position of the outer plate portion, and the folding groove portion is the width range of the key groove portion in the direction in which the folding base portion extends. Can be made wider than the keyway portion. By doing so, the key portion of the mating connector is introduced into the key groove portion after the folding end enters the opening formed in the folding base portion, so that the introduction becomes easy.

本発明において、上記キー溝部は、上記筒状体部および上記外板部の両方に形成されており、上記筒状体部に形成された溝部分と上記外板部に形成された溝部分とが連通しているようにすることができる。 In the present invention, the keyway portion is formed in both the tubular body portion and the outer plate portion, and the groove portion formed in the tubular body portion and the groove portion formed in the outer plate portion. Can be communicated with each other.

本発明は、以上のように、シールドケースが、筒状体部の相手コネクタ側に向く該相手コネクタの導入のための受入開口部の開口縁部における周方向の一部の範囲で折曲されて上記筒状体部の外面に重なって位置する外板部を有し、上記軸線方向に延び上記開口縁部に開口し相手コネクタのキー部を受け入れる切欠状のキー溝部が少なくとも上記筒状体部に形成されていることとしたので、シールドケースのキー溝部とその周辺の強度が向上される。 In the present invention, as described above, the shield case is bent in a part of the circumferential direction at the opening edge of the receiving opening for introducing the mating connector facing the mating connector side of the tubular body portion. The notch-shaped keyway portion that has an outer plate portion that is positioned so as to overlap the outer surface of the tubular body portion, extends in the axial direction, opens at the opening edge portion, and receives the key portion of the mating connector is at least the tubular body. Since it is decided that the portion is formed, the strength of the key groove portion of the shield case and its surroundings is improved.

図１は、本実施形態のシールド電気コネクタ（以下「コネクタ」という）１０である。図１及び以降の図においては、コネクタ１０についての方向性を理解しやすくするために、コネクタ１０と相手コネクタ６０とのコネクタ挿抜方向をＸ、コネクタ１０の端子配列方向をなすコネクタ幅方向をＹ、ＸＹ面に直角なコネクタ高さ方向をＺとして、立体空間座標軸を設定してある。なお、図１（Ａ）は上斜視図、図１（Ｂ）は下斜視図、図１（Ｃ）は部分平面図である。 FIG. 1 is a shielded electrical connector (hereinafter referred to as “connector”) 10 of the present embodiment. In FIGS. 1 and the following, in order to make it easier to understand the directionality of the connector 10, the connector insertion / removal direction between the connector 10 and the mating connector 60 is X, and the connector width direction forming the terminal arrangement direction of the connector 10 is Y. , The three-dimensional space coordinate axes are set with the connector height direction perpendicular to the XY plane as Z. 1 (A) is an upper perspective view, FIG. 1 (B) is a lower perspective view, and FIG. 1 (C) is a partial plan view.

コネクタ１０は、図１（Ｂ）及び図３に見られるように、金属帯状部材を屈曲して作られた二種の端子、すなわち複数の第一端子２０と複数の第二端子３０のそれぞれをコネクタ幅方向Ｙに配列保持する電気絶縁材製のハウジング４０にシールドケース５０が取りつけられており、図２に示される相手コネクタ６０をコネクタ挿抜方向Ｘで受け入れる。 As seen in FIGS. 1B and 3, the connector 10 has two types of terminals made by bending a metal strip-shaped member, that is, a plurality of first terminals 20 and a plurality of second terminals 30, respectively. The shield case 50 is attached to a housing 40 made of an electrically insulating material that holds the array in the connector width direction Y, and receives the mating connector 60 shown in FIG. 2 in the connector insertion / removal direction X.

第一端子２０と第二端子３０は、それぞれ１本ずつハウジング４０から抜出して示される図３に見られるように、コネクタ挿抜方向Ｘでの長さが異なっている。第一端子２０は、ハウジング４０により保持されるＬ字状の被保持部２１と、該被保持部２１からコネクタ挿抜方向Ｘで相手コネクタ６０に向く前方（図３にて左方）へ延びる接触部２２と、上記被保持部２１からコネクタ高さ方向Ｚで下方に向け延びる接続部２３とを有している。一方、第二端子３０は、ハウジング４０により保持されるＬ字状の被保持部３１と、該被保持部３１からコネクタ挿抜方向Ｘで相手コネクタ６０に向く前方へ延びる接触部３２と、上記被保持部３１からコネクタ高さ方向Ｚで下方に向け延び、さらに２回クランク状に屈曲した下端部に形成された接続部３３とを有している。第二端子３０はコネクタ挿抜方向Ｘで第一端子２０より長いので、第二端子３０の接続部３３が第一端子２０の接続部２３より後方に位置する。 The first terminal 20 and the second terminal 30 have different lengths in the connector insertion / removal direction X, as seen in FIG. 3, which is shown by extracting one from the housing 40.

The portion rearward of the notch groove S2 extends long and forms a leg shape without being bent or folded back, forming the rear fixed leg 51G described above. A side guide portion 51J is formed on the lower edge of the region M2.

副側板部５１−２Ｂは、その先端部分が屈曲線Ｆ２で屈曲され、ハウジング４０の底面の方へ巻き込まれる。主側板部５１−２Ａは、その側方に位置する領域Ｍ３につながっている。一方の領域Ｍ３の先端には、既述した結合溝５１Ｈ１が、他方の領域Ｍ３の先端には既述した結合突部５１Ｈ２が形成されている。 The tip of the sub-side plate portion 51-2B is bent at the bending line F2 and is wound toward the bottom surface of the housing 40. The main side plate portion 51-2A is connected to the region M3 located on the side thereof. The coupling groove 51H1 described above is formed at the tip of one region M3, and the coupling protrusion 51H2 described above is formed at the tip of the other region M3.

領域Ｍ４は、屈曲線Ｆ３で屈曲されることで後板部５１−４を形成しコネクタ幅方向Ｙの両端部が、さらに屈曲線Ｆ６で屈曲されて側板部５１−２に沿うような後板部屈曲部分５１−４Ａになる。 The region M4 is bent along the bending line F3 to form a rear plate portion 51-4, and both ends in the connector width direction Y are further bent by the bending line F6 to form a rear plate portion 51-2. It becomes a part bent portion 51-4A.

領域Ｍ５は、既述したようにコネクタ幅方向Ｙの中間部で没入した凹縁部５２Ａが形成され、コネクタ幅方向Ｙの両端寄り位置には係止孔部５２Ｂをなす窓部Ｐ４が形成されている。 In the region M5, as described above, a recessed edge portion 52A is formed in the middle portion in the connector width direction Y, and a window portion P4 forming the locking hole portion 52B is formed at a position near both ends in the connector width direction Y. ing.

領域Ｍ６は、図５にて下方へ向けた先細りで先端に向け延びる前方固定脚５２Ｃを有している。 Region M6 has a front fixed leg 52C that tapers downward and extends toward the tip in FIG.

このような図５の形状の金属板で形成される半加工品Ｍを図５に見られるように、屈曲線Ｆ１，Ｆ２，Ｆ６で山折りで屈曲した後、領域Ｍ３の結合突部５１Ｈ２を結合溝５１Ｈ１に結合して筒状体部５１を形成し、屈曲線ｆ４で谷折りして筒状体部５１を後方に開口した角筒状として、この筒状体部５１内にハウジングを後方から挿着する。その後、屈曲線Ｆ３で山折りの屈曲をするとともに係止片５１Ｃを折り曲げることで、図３に見られる形態とし、次いで折返線ｆ５で谷折りして外板部５２を形成することで図１（Ａ）〜（Ｃ）に見られるシールドケース５０としてハウジング４０に嵌着し係止片５１Ｃをハウジング本体部４１のシールドケース係止溝４１Ａに係止させてコネクタ１０を得る。 As can be seen in FIG. 5, the semi-processed product M formed of the metal plate having the shape of FIG. The tubular body portion 51 is formed by being coupled to the coupling groove 51H1 and valley-folded at the bending line f4 to form a square tubular body portion 51 having the tubular body portion 51 opened rearward, and the housing is rearwardly formed in the tubular body portion 51. Insert from. After that, the mountain fold is bent at the bending line F3 and the locking piece 51C is bent to obtain the form shown in FIG. 3, and then the valley is folded along the folding line f5 to form the outer plate portion 52. The connector 10 is obtained by fitting the locking piece 51C into the housing 40 as the shield case 50 seen in (A) to (C) and locking the locking piece 51C in the shield case locking groove 41A of the housing main body 41.

かかるコネクタ１０におけるシールドケース５０は、金属板の半加工品Ｍを屈曲そして折曲して完成品として形成された後は、図１（Ａ），（Ｂ）に見られるように、筒状体部５１の上板部５１−１に位置するキー溝部５１Ｄが前後方向に延びるとともに、シールドケース５０の受入開口部５１Ａにおける前端縁での２位置で折返用溝部５１Ｆを経て前方に開口している。キー溝部５１Ｄは外板部５２により上方では蓋状に塞がれており、キー溝部５１Ｄ周辺が外板部５２により強化されている。キー溝部５１Ｄはその側方（コネクタ幅方向Ｙ）でロック溝部５１Ｅに連通し、このロック溝部５１Ｅは、外板部５２に形成された係止孔部５２Ｂと連通していてロック溝部５１Ｅを実質的に上方に拡張するのと同じ形態をなしていて、相手コネクタ６０の後述のロック係止突部６５Ｂ（図２参照）との係止における係止能力を向上している。 The shield case 50 in the connector 10 is a tubular body as seen in FIGS. 1 (A) and 1 (B) after the semi-processed product M of the metal plate is bent and bent to form a finished product. The key groove portion 51D located in the upper plate portion 51-1 of the portion 51 extends in the front-rear direction, and is opened forward through the folding groove portion 51F at two positions at the front end edge of the receiving opening 51A of the shield case 50. .. The key groove portion 51D is closed in a lid shape above by the outer plate portion 52, and the periphery of the key groove portion 51D is reinforced by the outer plate portion 52. The key groove portion 51D communicates with the lock groove portion 51E on the side thereof (connector width direction Y), and the lock groove portion 51E communicates with the locking hole portion 52B formed in the outer plate portion 52 to substantially communicate with the lock groove portion 51E. It has the same form as the one that expands upward, and improves the locking ability of the mating connector 60 in locking with the lock locking protrusion 65B (see FIG. 2) described later.

受入開口部５１Ａでは、側板部５１−２の前端に突出する側方ガイド部５１Ｊがコネクタ幅方向Ｙで外側に傾斜して屈曲されており、また図５における領域Ｍ３の前縁部、すなわち、図１（Ａ），（Ｂ）における下側の前縁部がコネクタ高さ方向Ｚで外方（図にて下方へ傾斜して屈曲されていて下方ガイド部５１Ｋを形成し、さらには、外板部５２の折返基部５１Ｌ（図５にて折返線ｆ５の位置近傍）が丸みをもって折返されている。側方ガイド部５１Ｊ、下方ガイド部５１Ｋおよび折返基部５１Ｌはそれぞれ、相手コネクタ６０の嵌合の際に円滑な案内を行なう。 In the receiving opening 51A, the side guide portion 51J protruding toward the front end of the side plate portion 51-2 is inclined outward in the connector width direction Y and is bent, and the leading edge portion of the region M3 in FIG. 5, that is, The lower leading edge portion in FIGS. 1 (A) and 1 (B) is bent outward in the connector height direction Z (inclined and bent downward in the figure to form a lower guide portion 51K, and further, the outer side. The folding base portion 51L of the plate portion 52 (near the position of the folding line f5 in FIG. 5) is folded back with a roundness. The side guide portion 51J, the lower guide portion 51K, and the folding base portion 51L are fitted with the mating connector 60, respectively. We will provide smooth guidance at the time.

次に、かかるコネクタ１０に嵌合される相手コネクタ６０について図２にもとづき、簡単に説明する。 Next, the mating connector 60 fitted to the connector 10 will be briefly described with reference to FIG.

図２において、相手コネクタ６０は、この相手コネクタ６０のコネクタ本体部６１から図１のコネクタ１０へ向け突出する嵌合部を有している。コネクタ本体部６１は、上部ハウジング６２Ａと下部ハウジング６２Ｂとが結合したハウジング６２内に、ケーブルＣと嵌合部内の端子（図示せず）との結線が行われている。 In FIG. 2, the mating connector 60 has a fitting portion that projects from the connector main body portion 61 of the mating connector 60 toward the connector 10 of FIG. In the connector main body 61, the cable C and the terminal (not shown) in the fitting portion are connected to each other in the housing 62 in which the upper housing 62A and the lower housing 62B are connected.

嵌合部は、コネクタ１０へ向けコネクタ挿抜方向Ｘで突出する端子保持ハウジング６３と、端子保持ハウジング６３の周面に装着された金属板製のシールドケース６４と、端子保持ハウジング６３で保持されシールドケース６４から部分的に突出するロックアーム６５とを有している。 The fitting portion is held and shielded by a terminal holding housing 63 that protrudes toward the connector 10 in the connector insertion / removal direction X, a metal plate shield case 64 mounted on the peripheral surface of the terminal holding housing 63, and a terminal holding housing 63. It has a lock arm 65 that partially protrudes from the case 64.

端子保持ハウジング６３は、先端から奥部へ向け、コネクタ１０の嵌合部４２を受入れるスリット孔状の受入溝６３Ａが形成されていて、受入溝６３Ａ内では溝の上内壁面と下内壁面に、嵌合部４２における第二端子３０の接触部３２と第一端子２０の接触部２２と接触する対応端子の接触部がそれぞれ配置されている（対応端子は図２では見えない）。 The terminal holding housing 63 is formed with a slit hole-shaped receiving groove 63A for receiving the fitting portion 42 of the connector 10 from the tip to the back, and in the receiving groove 63A, the upper inner wall surface and the lower inner wall surface of the groove are formed. , The contact portion 32 of the second terminal 30 in the fitting portion 42 and the contact portion of the corresponding terminal that contacts the contact portion 22 of the first terminal 20 are arranged (the corresponding terminal is not visible in FIG. 2).

シールドケース６４は、端子保持ハウジング６３の周面を包囲している。このシールドケース６４の上面には、コネクタ幅方向Ｙの両端寄り位置にコネクタ挿抜方向Ｘに延びるスリット状の溝部６４Ａが形成されていて、この溝部６４Ａ内にロックアーム６５が配設されている。 The shield case 64 surrounds the peripheral surface of the terminal holding housing 63. A slit-shaped groove 64A extending in the connector insertion / removal direction X is formed on the upper surface of the shield case 64 at a position near both ends in the connector width direction Y, and a lock arm 65 is arranged in the groove 64A.

ロックアーム６５は、腕部６５Ａの先端にロック部としての鉤状のロック係止突部６５Ｂが設けられており、ロック係止突部６５Ｂのみがシールドケース６４の上面の位置から突出している。このロック係止突部６５Ｂは、下方に向け外力を受けたときにはロック係止突部６５Ｂが溝部６４Ａの内方に向け没するように、腕部６５Ａが弾性変形可能となっている。 The lock arm 65 is provided with a hook-shaped lock locking protrusion 65B as a lock portion at the tip of the arm portion 65A, and only the lock locking protrusion 65B protrudes from the position of the upper surface of the shield case 64. The arm portion 65A of the lock locking protrusion 65B can be elastically deformed so that the lock locking protrusion 65B sinks inward of the groove 64A when an external force is applied downward.

シールドケース６４は、その上面における先端縁部でコネクタ幅方向Ｙでの離間した２位置に、シールドケース６４を板厚方向に略半球状をなしてシールドケース６４の上面に突出するようにエンボス加工した突起状のキー部６６が形成されている。キー部６６の先端（板厚）面がコネクタ１０の嵌合部４２の端面に対して衝突して誤挿入防止を図る。その際、キー部６６と嵌合部４２は、端面同士の衝突となるので、互に衝突に対して強度が高い。このキー部６６は、既述のコネクタ１０におけるシールドケース５０の筒状体部５１の２位置に形成されたキー溝部５１Ｄとコネクタ幅方向Ｙで一致した位置に形成されている。同様に、上述したロックアーム６５は、筒状体部５１のキー溝部５１Ｄと連通して形成されたロック溝部５１Ｅとコネクタ幅方向Ｙで一致した位置にあり、相手コネクタ６０がコネクタ１０に対し正規位置まで嵌合したときに、ロックアーム６５のロック係止突部６５Ｂがロック溝部５１Ｅ内に係合するようにコネクタ挿抜方向Ｘでの位置が定められている。 The shield case 64 is embossed so as to form a substantially hemispherical shape in the plate thickness direction and project onto the upper surface of the shield case 64 at two positions separated from each other in the connector width direction Y at the tip edge portion on the upper surface thereof. A protruding key portion 66 is formed. The tip (thickness) surface of the key portion 66 collides with the end surface of the fitting portion 42 of the connector 10 to prevent erroneous insertion. At that time, since the key portion 66 and the fitting portion 42 collide with each other, the strength against the collision is high. The key portion 66 is formed at a position that coincides with the key groove portion 51D formed at two positions of the tubular body portion 51 of the shield case 50 in the connector 10 described above in the connector width direction Y. Similarly, the above-mentioned lock arm 65 is at a position corresponding to the lock groove portion 51E formed in communication with the key groove portion 51D of the tubular body portion 51 in the connector width direction Y, and the mating connector 60 is normal with respect to the connector 10. The position in the connector insertion / removal direction X is determined so that the lock locking protrusion 65B of the lock arm 65 engages in the lock groove portion 51E when fitted to the position.

このように構成された本実施形態のコネクタ１０とこれに対する相手コネクタ６０は、次の要領で使用される。 The connector 10 of the present embodiment and the mating connector 60 for the connector 10 of the present embodiment configured in this way are used in the following manner.

先ず、図１（Ａ），（Ｂ）に示されるコネクタ１０のハウジング本体部４１に設けられた脚部４１Ｂを所定の回路基板（図示せず）の位置決め用の孔部に挿入した後に、第一端子２０、第二端子３０、シールドケース５０を上記回路基板へ接続する。第一端子２０の接続部２３は回路基板のスルーホールに挿通かつ半田接続され、第二端子３０の接続部３３は上記回路基板の対応パッドに配され半田接続される。また、シールドケース５０の前方固定脚５２Ｃと後方固定脚５１Ｇを上記回路基板の対応グランド接続孔部にそれぞれ挿通かつ半田固定する。この前方固定脚５２Ｃと後方固定脚５１Ｇは、回路基板への固定に供するとともに、回路基板の所定グランド回路への導通を図る。 First, after inserting the leg 41B provided in the housing body 41 of the connector 10 shown in FIGS. 1A and 1B into a positioning hole of a predetermined circuit board (not shown), the first The one terminal 20, the second terminal 30, and the shield case 50 are connected to the circuit board. The connection portion 23 of the first terminal 20 is inserted into a through hole of the circuit board and solder-connected, and the connection portion 33 of the second terminal 30 is arranged on the corresponding pad of the circuit board and solder-connected. Further, the front fixing leg 52C and the rear fixing leg 51G of the shield case 50 are inserted and solder-fixed to the corresponding ground connection holes of the circuit board, respectively. The front fixing leg 52C and the rear fixing leg 51G are used for fixing to the circuit board and are intended to conduct the circuit board to a predetermined ground circuit.

次に、かかるコネクタ１０へ相手コネクタ６０を接続する。相手コネクタ６０には、すでにケーブルＣが相手コネクタ６０の端子と結線されている。相手コネクタ６０をコネクタ１０へ接続する際に、シールドケース６４で周面が覆われている端子保持ハウジング６３の部分をコネクタ１０のシールドケース５０の筒状体部５１における受入開口部５１Ａへ嵌入させると、この端子保持ハウジング６３に形成されている受入溝６３Ａ内へ、コネクタ１０のハウジング４０の前部をなす突出した嵌合部４２が嵌入する。かくして、嵌合部４２の面に配列されている第一端子２０の接触部２２と第二端子３０の接触部３２が相手コネクタ６０の対応端子と接続されるとともに、相手コネクタ６０のシールドケース６４がコネクタ１０のシールドケース５０の筒状体部５１と全周で包囲し、シールドされるようになる。 Next, the mating connector 60 is connected to the connector 10. The cable C is already connected to the terminal of the mating connector 60 to the mating connector 60. When connecting the mating connector 60 to the connector 10, the portion of the terminal holding housing 63 whose peripheral surface is covered with the shield case 64 is fitted into the receiving opening 51A in the tubular body portion 51 of the shield case 50 of the connector 10. Then, the protruding fitting portion 42 forming the front portion of the housing 40 of the connector 10 is fitted into the receiving groove 63A formed in the terminal holding housing 63. Thus, the contact portion 22 of the first terminal 20 and the contact portion 32 of the second terminal 30 arranged on the surface of the fitting portion 42 are connected to the corresponding terminals of the mating connector 60, and the shield case 64 of the mating connector 60 is connected. Encloses and shields the tubular body portion 51 of the shield case 50 of the connector 10 all around.

相手コネクタ６０のシールドケース６４で覆われた端子保持ハウジング６３をコネクタ１０のシールドケース５０の筒状体部５１における受入開口部５１Ａへ嵌入させる際、嵌入開始の際、コネクタ１０の筒状体部５１の受入開口部５１Ａの開口周囲縁に形成された、２つの側方ガイド部５１Ｊ、下方ガイド部５１Ｋ、丸みをもつ折返基部５１Ｌによりコネクタ幅方向Ｙそしてコネクタ高さ方向Ｚでの正規位置へ向け導入される。 When the terminal holding housing 63 covered with the shield case 64 of the mating connector 60 is fitted into the receiving opening 51A in the tubular body portion 51 of the shield case 50 of the connector 10, the tubular body portion of the connector 10 is fitted at the start of fitting. Two side guide portions 51J, a lower guide portion 51K, and a rounded folding base 51L formed on the peripheral edge of the opening of the receiving opening 51A of 51 to the normal positions in the connector width direction Y and the connector height direction Z. Introduced for.

しかる後、相手コネクタ６０のシールドケース６４に形成された２つのキー部６６がコネクタ１０の筒状体部５１における２つのキー溝部５１Ｄに案内される。キー溝部５１Ｄは、このキー溝部５１Ｄより幅広の折返用溝部５１Ｆにつながっているので、キー部６６はこの折返用溝部５１Ｆに容易に位置してからキー溝部５１Ｄへと導入される。仮に、相手コネクタ６０の端子保持ハウジング６３を覆うシールドケース６４がコネクタ幅方向Ｙで正規位置と異なる位置にキー部が設けられている場合は、相手コネクタ６０の異なる位置のキー部は、コネクタ１０のキー溝部５１Ｄに進入できず、したがって、正規でない相手コネクタの嵌入は不可となる。 After that, the two key portions 66 formed in the shield case 64 of the mating connector 60 are guided to the two key groove portions 51D in the tubular body portion 51 of the connector 10. Since the key groove portion 51D is connected to the folding groove portion 51F wider than the key groove portion 51D, the key portion 66 is easily located in the folding groove portion 51F and then introduced into the key groove portion 51D. If the shield case 64 covering the terminal holding housing 63 of the mating connector 60 is provided with a key portion at a position different from the normal position in the connector width direction Y, the key portion at a different position of the mating connector 60 is the connector 10. It is not possible to enter the keyway portion 51D of the above, and therefore it is not possible to insert a mating connector that is not regular.

コネクタ１０のシールドケース５０に形成された折返用溝部５１Ｆは、筒状体部５１及び外板部５２のコネクタ挿抜方向Ｘで相手コネクタ６０の方に向く板厚面で当接面５１Ｆ１（図１（Ａ），（Ｂ）参照）を形成する。一方、相手コネクタ６０のシールドケース６４にエンボス加工により形成されたキー部６６は、その板厚面でコネクタ１０の方に向く被当接面６６Ａ（図６参照）を形成する。したがって、相手コネクタ６０が正規の位置にキー部が形成されておらず正規の相手コネクタでない他の相手コネクタの場合、この他の相手コネクタのキー部の被当接面がコネクタ１０の当接面５１Ｆ１に当接して、他の相手コネクタの誤挿入を防止する。その際、キー部はエンボス加工に形成されていて、コネクタ高さ方向寸法を比較的大きくできるし、このキー部の被当接面とコネクタ１０の当接面５１Ｆ１は、板厚面で形成されているので、互いの当接時に対する強度は十分確保されている。仮に、コネクタ１０のシールドケース５０に、当接面５１Ｆ１を形成する折返用溝部５１Ｆが設けられておらず、シールドケース５０の外板部５２がコネクタ幅方向Ｙでの全域で丸みをもった折返基部５１Ｌを形成していると、上述の他の相手コネクタのキー部は、この折返基部５１Ｌの丸みとの当接によって、自らが下方に弾性変形してコネクタ挿抜方向Ｘでコネクタ１０内に向け誘導され誤挿入が生じてしまう可能性がある。これを防止するためにも、コネクタ１０における当接面５１Ｆ１は意義がある。 The folding groove portion 51F formed in the shield case 50 of the connector 10 is a contact surface 51F1 (FIG. 1) having a thick surface facing the mating connector 60 in the connector insertion / removal direction X of the tubular body portion 51 and the outer plate portion 52. (See (A) and (B)). On the other hand, the key portion 66 formed by embossing on the shield case 64 of the mating connector 60 forms a contact surface 66A (see FIG. 6) facing the connector 10 on the plate thickness surface thereof. Therefore, when the mating connector 60 is another mating connector in which the key portion is not formed at a regular position and is not a legitimate mating connector, the contact surface of the key portion of the other mating connector is the contact surface of the connector 10. It comes into contact with 51F1 to prevent erroneous insertion of other mating connectors. At that time, the key portion is formed by embossing so that the dimension in the height direction of the connector can be made relatively large, and the contact surface of the key portion and the contact surface 51F1 of the connector 10 are formed by a plate thickness surface. Therefore, the strength against contact with each other is sufficiently secured. Temporarily, the shield case 50 of the connector 10 is not provided with the folding groove 51F forming the contact surface 51F1, and the outer plate portion 52 of the shield case 50 is folded back in the entire area in the connector width direction Y. When the base portion 51L is formed, the key portion of the other mating connector described above is elastically deformed downward by the contact with the roundness of the folded base portion 51L, and is directed toward the inside of the connector 10 in the connector insertion / removal direction X. There is a possibility that it will be guided and erroneous insertion will occur. In order to prevent this, the contact surface 51F1 in the connector 10 is significant.

相手コネクタ６０がコネクタ挿抜方向Ｘで所定位置までコネクタ１０へ嵌入すると、嵌入開始時にコネクタ１０のシールドケース５０の筒状体部５１で圧せられて溝部６４Ａ内方に没していたロック係止突部６５Ｂが、ロックアーム６５の弾性変形からの解放に伴い、溝部６４Ａから突出し、筒状体部５１に形成されているロック溝部５１Ｅ、さらには、その上方に位置する外板部５２の係止孔部５２Ｂに突入し、相手コネクタ６０のコネクタ１０からの抜出を阻止する。この阻止は、筒状体部５１と外板部５２が２枚重ねになっていて、ロック溝部５１Ｅと係止孔部５２Ｂの両方からなされるので強力かつ確実となる。 When the mating connector 60 is fitted into the connector 10 to a predetermined position in the connector insertion / removal direction X, the lock is locked by being pressed by the tubular body portion 51 of the shield case 50 of the connector 10 and sunk in the groove portion 64A at the start of fitting. The protrusion 65B protrudes from the groove 64A as the lock arm 65 is released from the elastic deformation, and the lock groove 51E formed in the tubular body 51 and the outer plate 52 located above the lock groove 51E are engaged. It rushes into the stop 52B and prevents the mating connector 60 from being pulled out from the connector 10. This prevention is strong and reliable because the tubular body portion 51 and the outer plate portion 52 are overlapped with each other and are performed from both the lock groove portion 51E and the locking hole portion 52B.

相手コネクタ６０は、コネクタ１０に対し傾いた状態で嵌合開始される、いわゆる斜め嵌合の場合がある。例えば、図６のように、コネクタ挿抜方向Ｘにおける相手コネクタ６０の先端での一方の角部６０Ｒ１が他方の角部６０Ｒ２よりも大きくコネクタ１０の受入開口部５１Ａに進入してしまう。このコネクタ１０の受入開口部５１Ａ内には、コネクタ１０の端子２０の接触部２２と端子３０の接触部３２が両面のそれぞれに位置している板状の嵌合部４２（図３，図４参照）が位置している。このような場合、相手コネクタ６０の上記一方の角部６０Ｒ１が嵌合部４２の先端に衝突してしまい、比較的薄い板厚に形成されている嵌合部４２の先端を損傷してしまう可能性もある。 The mating connector 60 may be so-called diagonally fitted, in which fitting is started in a state of being tilted with respect to the connector 10. For example, as shown in FIG. 6, one corner 60R1 at the tip of the mating connector 60 in the connector insertion / removal direction X enters the receiving opening 51A of the connector 10 larger than the other corner 60R2. In the receiving opening 51A of the connector 10, the contact portion 22 of the terminal 20 of the connector 10 and the contact portion 32 of the terminal 30 are located on both sides of the plate-shaped fitting portion 42 (FIGS. 3 and 4). See) is located. In such a case, the one corner portion 60R1 of the mating connector 60 may collide with the tip of the fitting portion 42, and the tip of the fitting portion 42 formed to have a relatively thin plate thickness may be damaged. There is also sex.

かかる事態を確実に防止するには、予想される最大の傾き角でも、相手コネクタ６０の上記一方の角部６０Ｒ１がコネクタ１０の嵌合部４２の先端に衝突しないように、キー部６６の被当接面６６Ａがコネクタ１０の当接面５１Ｆ１に当接して、相手コネクタの所定以上の誤挿入を防止する。また、図６に破線で示すように、この嵌合部４２の先端をコネクタ挿抜方向Ｘでコネクタ１０の受入開口部５１Ａの開口端から距離Ｘ１だけ没した位置に定める。上記２つの組合せで上記衝突が確実に防止される。 In order to reliably prevent such a situation, the key portion 66 is covered so that the one corner portion 60R1 of the mating connector 60 does not collide with the tip of the fitting portion 42 of the connector 10 even at the maximum expected tilt angle. The contact surface 66A comes into contact with the contact surface 51F1 of the connector 10 to prevent erroneous insertion of the mating connector beyond a predetermined value. Further, as indicated by a broken line in FIG. 6, determined from the open end of the receiving opening 51A of the connector 10 to the tip of the fitting portion 42 in the connector insertion direction X to a distance X 1 only died position. The combination of the above two ensures that the collision is prevented.

相手コネクタ６０は、上下方向で傾いた状態で嵌合開始される場合は、コネクタ１０の筒状体部５１における下方ガイド部５１Ｋや折返基部５１Ｌにより案内され嵌合の進行に伴いその傾きは小さくなる。 When the mating connector 60 is started to be fitted in a state of being tilted in the vertical direction, the mating connector 60 is guided by the lower guide portion 51K and the folded base portion 51L in the tubular body portion 51 of the connector 10, and the tilt becomes smaller as the fitting progresses. Become.

本発明において、図示された形態に限定されず、変形が可能である。例えば、図７に示すごとく、キー溝部５１Ｄは、シールドケース５０の筒状体部５１のみならず、外板部５２にも形成することができる。その場合、シールドケース５０の折返用溝部５１Ｆを介して筒状体部５１のキー溝部５１Ｄと外板部５２に形成されるキー溝部５２Ｄとがコネクタ幅方向Ｙで同位置に位置してコネクタ高さ方向Ｚで連通し、板厚方向、すなわちコネクタ高さ方向Ｚでキー溝が拡張した形態のキー溝部をなす。この場合、外板部５２における係止孔部５２Ｂはキー溝部５２Ｄと連通する。 In the present invention, the form is not limited to the illustrated form and can be modified. For example, as shown in FIG. 7, the keyway portion 51D can be formed not only on the tubular body portion 51 of the shield case 50 but also on the outer plate portion 52. In that case, the key groove portion 51D of the tubular body portion 51 and the key groove portion 52D formed in the outer plate portion 52 are located at the same position in the connector width direction Y via the folding groove portion 51F of the shield case 50, and the connector height. It communicates in the longitudinal direction Z to form a key groove portion in which the key groove is expanded in the plate thickness direction, that is, in the connector height direction Z. In this case, the locking hole portion 52B in the outer plate portion 52 communicates with the key groove portion 52D.
