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). More specifically, the present invention relates to a fitting structure with a receptacle connector that contributes to downsizing (smaller 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。   A coaxial cable connector generally includes 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 of 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 receptacle conductor of the receptacle connector against the annular convex portion formed by the protrusion on the inner wall of the cylindrical fitting portion of the outer conductor shell. An annular recess formed in the inner wall of the cylindrical fitting portion of the outer conductor shell or crushed on the inner wall of the outer conductor shell. Similarly, the receptacle connector is also provided on the outer wall of the cylindrical fitting portion of the outer conductor. An annular recess formed by crushing or an annular projection formed by 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 Patent Application Laid-Open No. 2012-230820 (Patent Document 1), the lock portion formed in an annular concave shape provided on the inner wall of the outer side contact, The connection state between the connectors is maintained by being fitted into a lock portion formed in an 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。   In the configuration 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 as in the conventional example described above, each fitting is performed when fitting. 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 equal, the thickness of the portion where each fitting portion overlaps is approximately 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 needs a thickness to maintain a strength that does not deform due to crushing when fitting, so when trying to reduce the size of the coaxial cable connector, Since the thickness of the wall of the fitting portion cannot be made thinner than a thickness that can maintain the required strength, the thickness of the wall can be a problem that hinders the 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, a groove-shaped inward locking recess extending in a direction perpendicular to the fitting direction and at least a part of the inner wall of the fitting portion of the coaxial cable connector, and a hook-shaped inner portion protruding from the inward locking recess Similarly, a groove-like outward lock recess extending in a direction perpendicular to the fitting direction and at least a part of the outer wall of the fitting portion of the receptacle connector, and the outward lock recess When the connectors are connected to each other, 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 are connected to the receptacle connector. The thickness of the part where the wall of each fitting part overlaps by fitting to the outward locking concave part and the outward locking convex part provided on the outer wall of the fitting part of the fitting part of the coaxial cable connector Wall thickness Coaxial cable connector configured to be thinner than the sum of the thicknesses of the mating portions of the receptacle connector (that is, the thickness of two walls obtained by simply superimposing the walls of each mating portion) And a connector system.

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 lock recess provided on the inner wall of the fitting portion of the coaxial cable connector is recessed deeper than the inner wall surface so that the inward lock protrusion does not protrude beyond the inner wall surface. Similarly, the outward locking concave portion provided on the outer wall of the receptacle connector fitting portion is recessed deeper than the outer wall surface, and the outward locking convex portion does not protrude beyond the outer wall surface. Thus, when the inward lock convex part fits into the outward lock concave part, and the inward lock concave part fits into the outward lock convex part, the thickness of the part where the wall of each fitting part overlaps is set. A coaxial cable connector and connector system that can be made thinner are provided.

The thickness of the part where the walls of each fitting part overlap each other is simply determined by fitting each into the outward locking convex part that does not protrude and the outward locking concave part that is recessed deeper than the surface of the outer wall. Since the thickness of the wall of the two fitting portions can be made thinner than the thickness of the two fitting walls, the thickness of the fitting portion of the coaxial cable connector can be maintained while maintaining the thickness of the fitting portion of the coaxial cable connector. The diameter can be designed to be smaller, contributing to the miniaturization of the coaxial cable connector.

For example, in the conventional example shown in Patent Document 1, even if the concave portion or the convex portion of one fitting portion is fitted to the convex portion or the concave portion of the other fitting portion, the respective overlapping portions overlap each other. Is not 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 one embodiment of the present invention, the inward direction provided on the inner wall of the substantially annular fitting portion constituted by at least the cylindrical portion 14 of the coaxial cable connector 1. The lock recess 20 is recessed deeper than the surface of the inner wall, the inward lock protrusion 21 does not protrude from the surface of the inner wall, and the inclined portion 22 is configured to expand outward while being recessed from the surface of the inner wall. Further, 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 is configured not to protrude beyond the surface of the outer wall. As a result, the locking mechanism of the inward lock convex portion 21 and the outward lock concave portion 47 are fitted to each other, and the inward lock concave portion 20 is fitted to the outward lock convex portion 42. In the range of the fitting direction of each outer conductor, the thickness of one of the original surfaces is the height corresponding to the concave portion formed so that the other surface is depressed. The thickness of the overlapped portion 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 shell 10 and the outer conductor shell 40 face each other is referred to as a fitting range 60. . That is, the fitting range 60 is a portion where the substantially annular fitting portion including at least the cylindrical portion 14 of the coaxial cable connector 1 covers the fitting portion 44 of the receptacle connector 2 (in the embodiment shown in FIG. 6, the cylindrical portion 14 The overlapping part (the part in the range shown by the code | symbol 60 in FIG. 6) from the front-end | tip part (edge part of the guidance | induction part 23) to the front-end | tip part (edge part of the outward lock | rock convex part 42) of the fitting part 44 of FIG. ) 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, the opposing surfaces of the outer conductor shell of at least one connector, except for the locking mechanism, are recessed and inclined portions that are recessed from the surface in the fitting range. The surface of the fitting range 60 is in a position overlapping in the radial direction. For example, as shown in FIG. 6, in the fitting range 60, the surface overlap 70 is the surface of the inner wall of the fitting portion (tubular 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 locking convex portion 42) are the portions that overlap in the radial direction (the portion in the 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 the miniaturization of the coaxial cable connector. In addition, although the height of each convex part was not projected from the thickness of the original metal plate, that is, the surface of the inner wall, it is also possible to project from the surface of the inner wall within a range less than the depth at which the corresponding concave part is depressed. It is.

また、内向きロック凸部２１の頂面（又は頂点）が、筒部１４の内壁（嵌合部の内壁）の表面よりも低い位置にあるように構成し、外向きロック凸部４２の頂面（又は頂点）が、嵌合部４４の外壁の表面よりも低い位置にあるように構成しても、上記と同様の効果を得ることができる。   Further, the top surface (or the vertex) of the inward lock convex portion 21 is configured to be lower than the surface of the inner wall of the cylindrical portion 14 (the inner wall of the fitting portion), and the top of the outward lock convex portion 42 is formed. Even if the surface (or vertex) is configured to be at a position lower than the surface of the outer wall of the fitting portion 44, the same effect as described above can be obtained.

本発明の個々の実施例は、独立した実施例ではなく、それぞれ組み合わせて適宜実施することができる。   Each example of the present invention is not an independent example, and can be appropriately implemented in combination.

本発明に係る同軸ケーブルコネクタ及びコネクタシステムは、小型電子機器内の電気信号伝送等に用いることができる。   The coaxial cable connector and the connector system according to the present invention can be used for electric signal transmission in a small electronic device.
