Description

本発明は、同軸ケーブルコネクタ（プラグ側コネクタ）と相手側のレセプタクルコネクタ（基板側コネクタ）からなるコネクタシステムに関する。具体的には、同軸ケーブルコネクタの小型化（小径化）に寄与する、レセプタクルコネクタとの嵌合構造に関する。 The present invention relates to a connector system including a coaxial cable connector (plug side connector) and a mating receptacle connector (board side connector). Specifically, the present invention relates to a fitting structure with a receptacle connector that contributes to downsizing (reduction in diameter) of a coaxial cable connector.

同軸ケーブルコネクタは、一般的に、端子と、該端子を支持するハウジングと、該ハウジングの少なくとも一部と同軸ケーブルの少なくとも一部を覆う外部導体シェルと、同軸ケーブルを含む。一方、相手側のレセプタクルコネクタは、端子と、該端子を支持するハウジングと、該ハウジングの少なくとも一部を覆う外部導体シェルという部品構成である。同軸ケーブルコネクタは、外部導体シェルの円筒状の嵌合部の内壁に、突出しにより形成された環状凸部に対して、レセプタクルコネクタの部導体の円筒状の嵌合部の外壁につぶしにより形成された環状凹部がはめ込まれるか、外部導体シェルの円筒状の嵌合部の内壁につぶしにより形成された環状凹部を備え、同様に、レセプタクルコネクタも外部導体の円筒状の嵌合部の外壁に、つぶしにより形成された環状凹部又は突出しにより形成された環状凸部を備える。 Coaxial cable connectors generally include a terminal, a housing that supports the terminal, an outer conductor shell that covers at least a portion of the housing and at least a portion of the coaxial cable, and a coaxial cable. On the other hand, the mating receptacle connector has a component structure including a terminal, a housing that supports the terminal, and an outer conductor shell that covers at least a part of the housing. The coaxial cable connector is formed by crushing on the outer wall of the cylindrical fitting portion of the partial conductor of the receptacle connector, against the annular convex portion formed by the projection on the inner wall of the cylindrical fitting portion of the outer conductor shell. The annular connector is fitted into the outer conductor shell or provided with an annular recess formed by crushing on the inner wall of the cylindrical fitting portion of the outer conductor shell, and similarly, the receptacle connector is also provided on the outer wall of the cylindrical fitting portion of the outer conductor. An annular concave portion formed by crushing or an annular convex portion formed by a protrusion is provided.

同軸ケーブルコネクタの嵌合部に設けられた環状凸部又は環状凹部が、レセプタクルコネクタの嵌合部に設けられた環状凹部又は環状凸部に嵌め込まれることで、同軸ケーブルコネクタとレセプタクルコネクタの接続状態が維持される。例えば、特開２０１２−２３０８２０号公報（特許文献１）に記載されたプラグコネクタ（同軸ケーブルコネクタ）の従来例では、外方側コンタクトの内壁に設けられた環状凹状に形成されたロック部が、レセプタクルコネクタの内方側コンタクトの外壁に設けられた環状凸状に形成されたロック部に嵌め込まれることで、コネクタ同士の接続状態が維持される。 The connection state of the coaxial cable connector and the receptacle connector by fitting the annular convex portion or annular concave portion provided in the fitting portion of the coaxial cable connector into the annular concave portion or annular convex portion provided in the fitting portion of the receptacle connector. Is maintained. For example, in the conventional example of the plug connector (coaxial cable connector) described in Japanese Unexamined Patent Application Publication No. 2012-230820 (Patent Document 1), an annular concave lock portion provided on the inner wall of the outer contact is The connector is maintained in the connected state by being fitted into the lock portion formed in the annular convex shape provided on the outer wall of the inner contact of the receptacle connector.

特開２０１２−２３０８２０号公報JP, 2012-230820, A

上述した従来例のように、同軸ケーブルコネクタの嵌合部内壁に設けられた凹部をレセプタクルコネクタの嵌合部外壁に設けられた凸部に嵌め合せる構成では、嵌め合せた際に各々の嵌合部の壁が重なった部分の厚さは、同軸ケーブルコネクタの嵌合部の壁の厚さとレセプタクルコネクタの嵌合部の厚さを足し合わせた厚さとなる。例えば、各々の嵌合部の壁の厚さが等しい場合には、各々の嵌合部が重なる部分の厚さは、各嵌合部の壁の厚さのほぼ２倍となる。 As in the above-mentioned conventional example, in the structure in which the concave portion provided on the inner wall of the fitting portion of the coaxial cable connector is fitted to the convex portion provided on the outer wall of the fitting portion of the receptacle connector, the respective mating parts are fitted when they are fitted. The thickness of the portion where the wall of the portion overlaps is the sum of the thickness of the wall of the fitting portion of the coaxial cable connector and the thickness of the fitting portion of the receptacle connector. For example, when the wall thickness of each fitting portion is the same, the thickness of the overlapping portion of each fitting portion is almost twice the thickness of the wall of each fitting portion.

各々の嵌合部の壁は、嵌合する際につぶれるなどして変形しない程度の強度を維持するための厚さを必要とするため、同軸ケーブルコネクタの小型化を図ろうとする際には、嵌合部の壁の厚さを必要な強度が維持可能な厚さよりも薄くすることができないため、当該壁の厚さは、同軸ケーブルコネクタの小型化を妨げる１つの問題となり得る。 The wall of each fitting portion requires a thickness for maintaining strength such that it is not deformed by being crushed during fitting, so when attempting to downsize the coaxial cable connector, Since the thickness of the wall of the fitting portion cannot be made thinner than the thickness that can maintain the required strength, the thickness of the wall can be one problem that prevents miniaturization of the coaxial cable connector.

そこで、同軸ケーブルコネクタの嵌合部の内壁の少なくとも一部分に、嵌合方向に対して垂直な方向に延びた溝状の内向きロック凹部と、該内向きロック凹部よりも突き出た畝状の内向きロック凸部とを設け、同様に、レセプタクルコネクタの嵌合部の外壁の少なくとも一部分に、嵌合方向に対して垂直な方向に延びた溝状の外向きロック凹部と、該外向きロック凹部よりも突き出た畝状の外向きロック凸部を設け、コネクタ同士を接続した際に、同軸ケーブルコネクタの嵌合部の内壁に設けられた内向きロック凸部及び内向きロック凹部が、レセプタクルコネクタの嵌合部の外壁に設けられた外向きロック凹部及び外向きロック凸部に嵌り合うことで、各々の嵌合部の壁が重なった部分の厚さが、同軸ケーブルコネクタの嵌合部の壁の厚さとレセプタクルコネクタの嵌合部の厚さを足し合わせた厚さ（すなわち、単に各々の嵌合部の壁を重ね合せた２枚の壁の厚さ）よりも薄くなるように構成された同軸ケーブルコネクタ及びコネクタシステムを提供する。 Therefore, at least a part of the inner wall of the fitting portion of the coaxial cable connector is provided with a groove-shaped inward locking recess extending in a direction perpendicular to the fitting direction and a ridge-shaped inner recess protruding from the inward locking recess. And a groove-shaped outward lock concave portion extending in a direction perpendicular to the fitting direction on at least a part of the outer wall of the fitting portion of the receptacle connector. When the connectors are connected to each other by providing a ridge-shaped outward lock convex portion that is more protruding than the inward lock convex portion and the inward lock concave portion provided on the inner wall of the fitting portion of the coaxial cable connector, the receptacle connector By fitting in the outward lock concave portion and the outward lock convex portion provided on the outer wall of the fitting portion, the thickness of the portion where the walls of the fitting portions overlap is the same as that of the fitting portion of the coaxial cable connector. It is configured to be thinner than the sum of the thickness of the wall and the thickness of the mating portion of the receptacle connector (that is, the thickness of two walls obtained by simply overlapping the walls of each mating portion). A coaxial cable connector and a connector system are provided.

より具体的には、同軸ケーブルコネクタの嵌合部の内壁に設けられた内向きロック凹部は、内壁の表面よりも奥に窪み、内向きロック凸部は内壁の表面よりも突出していないように構成し、同様に、レセプタクルコネクタの嵌合部の外壁に設けられた外向きロック凹部は、外壁の表面よりも奥に窪み、外向きロック凸部は外壁の表面よりも突出していないように構成したことによって、内向きロック凸部が外向きロック凹部に嵌り合い、内向きロック凹部が外向きロック凸部と嵌り合った際に、各々の嵌合部の壁が重なった部分の厚さをより薄くすることできる同軸ケーブルコネクタ及びコネクタシステムを提供する。 More specifically, the inward locking concave portion provided on the inner wall of the fitting portion of the coaxial cable connector is recessed deeper than the surface of the inner wall, and the inward locking convex portion does not protrude beyond the surface of the inner wall. Similarly, the outward lock recess provided on the outer wall of the mating portion of the receptacle connector is recessed deeper than the surface of the outer wall, and the outward lock protrusion does not protrude beyond the surface of the outer wall. By doing so, when the inward locking convex portion fits into the outward locking concave portion and the inward locking concave portion fits into the outward locking convex portion, the thickness of the portion where the walls of each fitting portion overlap is determined. A coaxial cable connector and a connector system that can be made thinner.

Instead, the outward lock concave portion 47 may be formed on the fitting portion 44 on the side closer to the mating connector than the outward lock convex portion 42.

図５は、同軸ケーブルコネクタをレセプタクルコネクタに接続する前の状態と接続した後の状態の断面を示す。同軸ケーブルコネクタ１の断面は、図４（ｂ）に示す、筒部３２の中心を通る線ｂ−ｂに沿って垂直に切断した断面であり、レセプタクルコネクタ２の断面は、図４（ｃ）に示す、筒部４４の中心を通る直線ｃ−ｃに沿って垂直に切断した断面である。図５に示されるように、外向きロック凹部４７は、嵌合部４４の外壁の表面よりも奥に窪むように形成され、外向きロック凸部４２は嵌合部４４の外壁の表面よりも突出しないように形成される。 FIG. 5 shows cross sections of the coaxial cable connector before and after being connected to the receptacle connector. The cross section of the coaxial cable connector 1 is a cross section cut perpendicularly along a line bb passing through the center of the tubular portion 32 shown in FIG. 4( b ), and the cross section of the receptacle connector 2 is shown in FIG. 4( c ). 2 is a cross section vertically cut along a straight line cc passing through the center of the tubular portion 44 shown in FIG. As shown in FIG. 5, the outward lock concave portion 47 is formed so as to be recessed deeper than the surface of the outer wall of the fitting portion 44, and the outward lock convex portion 42 projects from the surface of the outer wall of the fitting portion 44. Not formed.

When the mating portion and the annular fitting portion 44 of the receptacle connector 2 are fitted to each other, the guide portion 23 formed so as to expand outside the surface of the outer wall of the tubular portion 14 is formed on both sides of the coaxial cable connector 1. Since it is inside the outer wall of a certain wall portion 13 and the mounting portion 48 of the receptacle connector 2, it does not affect the miniaturization (reduction in diameter) of the coaxial cable connector.

図６は、図５に示す状態から同軸ケーブルコネクタをレセプタクルコネクタに接続した後の状態を示す断面図である。同軸ケーブルコネクタ１の少なくとも筒部１４から構成される略環状の嵌合部と、レセプタクルコネクタ２の環状の嵌合部４４とが嵌め合わされた状態では、内向きロック凸部２１及び内向きロック凹部２０が、外向きロック凹部４７及び外向きロック凸部４２に嵌り合って、同軸ケーブルコネクタ１の外部導体シェル１０とレセプタクルコネクタ２の外部導体シェル４０とが電気的に接続される。つまり、同軸ケーブルコネクタ１とレセプタクルコネクタ２を含むコネクタシステムは、互いに嵌合する内向きロック凸部２１と外向きロック凹部４７からなるロック機構と、互に嵌合する内向きロック凹部２０と外向きロック凸部４２からなる付加的なロック機構を備える。また、同軸ケーブルコネクタ１の接触部３１の間に、レセプタクルコネクタ２の接触部４２が挟まれて電気的に接続される。 FIG. 6 is a cross-sectional view showing a state after connecting the coaxial cable connector to the receptacle connector from the state shown in FIG. The inward locking projection 21 and the inward locking recess are provided in a state where the substantially annular fitting portion formed of at least the tubular portion 14 of the coaxial cable connector 1 and the annular fitting portion 44 of the receptacle connector 2 are fitted together. 20 is fitted into the outward lock concave portion 47 and the outward lock convex portion 42, and the outer conductor shell 10 of the coaxial cable connector 1 and the outer conductor shell 40 of the receptacle connector 2 are electrically connected. That is, the connector system including the coaxial cable connector 1 and the receptacle connector 2 includes a locking mechanism including the inward locking convex portion 21 and the outward locking concave portion 47 that are fitted to each other, and the inward locking concave portion 20 and the outer portion that are fitted to each other. An additional locking mechanism consisting of the orientation locking projection 42 is provided. Further, the contact portion 42 of the receptacle connector 2 is sandwiched between the contact portions 31 of the coaxial cable connector 1 to be electrically connected.

同軸ケーブルコネクタ１の嵌合部の壁（すなわち、筒部１４の壁）の厚さをｔ1とし、レセプタクルコネクタ２の嵌合部４４の壁の厚さをｔ2とした場合、単に、各々の嵌合部の壁が重なった部分の厚さはｔ1＋ｔ2である。例えば、特許文献１に示した従来例では、一方の嵌合部の凹部又は凸部が、他方の嵌合部の凸部又は凹部に嵌り合ったとしても、各々の嵌合部が重なった部分の厚さはｔ1＋ｔ2よりも薄くならない。 If the thickness of the wall of the fitting portion of the coaxial cable connector 1 (that is, the wall of the tubular portion 14) is t 1 and the thickness of the wall of the fitting portion 44 of the receptacle connector 2 is t 2 , then simply The thickness of the portion where the walls of the fitting portion of the above overlap is t 1 +t 2 . For example, in the conventional example shown in Patent Document 1, even if the concave portion or the convex portion of one fitting portion fits into the convex portion or the concave portion of the other fitting portion, the portions where the respective fitting portions overlap each other. Does not become thinner than t 1 +t 2 .

これに対して、本発明の一実施形態に係る同軸ケーブルコネクタ１及びレセプタクルコネクタ２では、同軸ケーブルコネクタ１の少なくとも筒部１４から構成される略環状の嵌合部の内壁に設けられた内向きロック凹部２０は、内壁の表面よりも奥に窪み、内向きロック凸部２１は内壁の表面よりも突出しておらず、傾斜部２２は内壁の表面から窪みながら外側に拡がるように構成し、同様に、レセプタクルコネクタ２の嵌合部４４の外壁に設けられた外向きロック凹部４７は、外壁の表面よりも奥に窪み、外向きロック凸部４２は外壁の表面よりも突出していないように構成したことによって、内向きロック凸部２１と外向きロック凹部４７のロック機構が互いに嵌り合い、内向きロック凹部２０が外向きロック凸部４２と嵌り合った際に、各々の外部導体の嵌合方向の範囲では一方の厚みが元々の表面の高さの部分は他方の表面が窪むように凹部を形成して対応しているので、嵌合部の金属板の壁が重なった部分の厚さをｔ1＋ｔ2より薄くすることができる。 On the other hand, in the coaxial cable connector 1 and the receptacle connector 2 according to the embodiment of the present invention, the coaxial cable connector 1 faces inwardly provided on the inner wall of the substantially annular fitting portion formed of at least the tubular portion 14. The lock recess 20 is recessed deeper than the surface of the inner wall, the inward lock projection 21 is not protruded beyond the surface of the inner wall, and the inclined portion 22 is configured to be recessed from the surface of the inner wall and spread outward. In addition, the outward lock concave portion 47 provided on the outer wall of the fitting portion 44 of the receptacle connector 2 is recessed deeper than the surface of the outer wall, and the outward lock convex portion 42 does not protrude from the surface of the outer wall. By doing so, when the locking mechanisms of the inward locking convex portion 21 and the outward locking concave portion 47 are fitted to each other and the inward locking concave portion 20 is fitted to the outward locking convex portion 42, the fitting of the respective outer conductors is performed. In the range of the direction, one thickness corresponds to the original height of the surface by forming a recess so that the other surface is recessed, so the thickness of the part where the metal plate walls of the fitting part overlap It can be made thinner than t 1 +t 2 .

ここで、同軸ケーブルコネクタ１とレセプタクルコネクタ２が嵌合した際に、各々の外部導体シェル１０と外部導体シェル４０の互いの表面が対面する部分の嵌合方向の範囲を嵌合範囲６０と呼ぶ。すなわち、嵌合範囲６０とは、同軸ケーブルコネクタ１の少なくとも筒部１４を含む略環状の嵌合部がレセプタクルコネクタ２の嵌合部４４を覆う部分（図６に示す実施例では、筒部１４の先端部（誘導部２３の縁部）から嵌合部４４の先端部（外向きロック凸部４２の縁部）のまでの重なった部分（図６中の符号６０で示す範囲にある部分））の嵌合方向での範囲である。 Here, when the coaxial cable connector 1 and the receptacle connector 2 are fitted to each other, a range in a fitting direction of a portion where the surfaces of the outer conductor shells 10 and 40 face each other is called a fitting range 60. .. That is, the fitting range 60 is a portion in which the substantially annular fitting portion including at least the tubular portion 14 of the coaxial cable connector 1 covers the fitting portion 44 of the receptacle connector 2 (the tubular portion 14 in the embodiment shown in FIG. 6). From the front end portion (edge portion of the guide portion 23) to the front end portion of the fitting portion 44 (edge portion of the outward lock convex portion 42) (portion within the range indicated by reference numeral 60 in FIG. 6) ) Is the range in the fitting direction.

同軸ケーブルコネクタ１とレセプタクルコネクタ２が嵌合した際には、ロック機構を除いて、少なくとも一方のコネクタの外部導体シェルの対向する表面は、嵌合範囲で当該表面よりも窪んだ凹部と傾斜部を含む窪部を形成しており、嵌合範囲６０の表面が径方向で重複する位置にある。例えば、図６に示されるように、嵌合範囲６０において、表面の重複７０とは、同軸ケーブルコネクタ１の嵌合部（筒部１４）の内壁の表面（及び内向きロック凸部２１の頂面）とレセプタクルコネクタ２の嵌合部４４の外壁の表面（及び外向きロック凸部４２の頂面）とが径方向で重なる部分（図６中の符号７０で示す範囲にある部分）をいう。 When the coaxial cable connector 1 and the receptacle connector 2 are fitted to each other, except for the lock mechanism, the facing surface of the outer conductor shell of at least one of the connectors has a concave portion and an inclined portion that are recessed in the fitting range from the surface. Is formed, and the surfaces of the fitting range 60 are at positions where they overlap in the radial direction. For example, as shown in FIG. 6, in the fitting range 60, the surface overlap 70 means that the surface of the inner wall of the fitting portion (cylindrical portion 14) of the coaxial cable connector 1 (and the top of the inward locking convex portion 21). Surface) and the surface of the outer wall of the fitting portion 44 of the receptacle connector 2 (and the top surface of the outward lock convex portion 42) are radially overlapped (a portion within a range indicated by reference numeral 70 in FIG. 6). ..

この結果として、同軸ケーブルコネクタの嵌合部の強度を維持できる厚さを保ちつつ、嵌合部の径をより小さく設計し、同軸ケーブルコネクタの小型化に寄与することができる。なお、それぞれの凸部の高さを元々の金属板の厚み、つまり、内壁の表面から突出しないとしたが、対応する凹部の窪んだ深さ未満の範囲で内壁の表面から突出させることも可能である。 As a result, the diameter of the fitting portion can be designed to be smaller while maintaining the thickness capable of maintaining the strength of the fitting portion of the coaxial cable connector, which can contribute to downsizing of the coaxial cable connector. In addition, although the height of each projection is not projected from the original thickness of the metal plate, that is, the surface of the inner wall, it is possible to project the height of the projection from the surface of the inner wall within a range less than the recessed depth of the corresponding recess.
