Description

本発明は、同軸コネクタに関し、特に小型の同軸ケーブルコネクタに関する。   The present invention relates to a coaxial connector, and more particularly to a small coaxial cable connector.

同軸ケーブルコネクタは、例えば、移動電話、スマートフォン、パーソナルデジタルアシスタント(PDA)、ノート型パソコンといった情報機器や、家電製品などの電気機器の内部に使用される。近年は、情報機器の小型化により、コネクタの小型化も進んでいる。特許文献1に、小型のコネクタであっても安定的に生産できる、同軸ケーブル用のレセプタクルコネクタの製造方法の一例が開示されている。このレセプタクルコネクタの中心導体(中心端子)は、厚い板状片を所定の形状に打ち抜き加工し、次に打ち抜き加工した板状片を、相手端子と接触する接触部等を形成するために、潰し加工(折り曲げ加工)を施し、次に潰し加工を施した中心導体の余分な部分を削除する打ち抜き加工し、次に打ち抜き加工をした中心導体を、外部導体と共に絶縁体ハウジングと一体成形して、最後に、ケーブルと接続する部分を形成することによって、同軸ケーブル用のコネクタを製造する方法について開示がある。この従来技術は、安定して生産でき、十分な有効嵌合長を確保でき、かつ、有効嵌合長のコントロールも可能で、接触信頼性に影響のない安定した接続を得ることができるとの効果を有する。   A coaxial cable connector is used, for example, in an information device such as a mobile phone, a smartphone, a personal digital assistant (PDA), or a notebook personal computer, or an electric device such as a home appliance. In recent years, the miniaturization of information equipment has led to the miniaturization of connectors. Patent Document 1 discloses an example of a method of manufacturing a receptacle connector for a coaxial cable that can be stably produced even with a small connector. The center conductor (center terminal) of this receptacle connector is formed by punching a thick plate-like piece into a predetermined shape, and then crushing the punched plate-like piece to form a contact portion or the like that contacts the mating terminal. After punching to remove the excess portion of the center conductor that has been subjected to processing (bending), and then crushing, then the center conductor that has been punched is integrally formed with the insulator housing together with the outer conductor, Finally, there is disclosed a method of manufacturing a connector for a coaxial cable by forming a portion that connects to the cable. With this conventional technology, it is possible to stably produce, secure a sufficient effective fitting length, control the effective fitting length, and obtain a stable connection that does not affect the contact reliability. Has an effect.

特許文献1に開示のコネクタは、特許文献1の図9に示されるように、絶縁体42(ハウジング)は、接触部441(中心端子)を入れるための貫通孔421を有している。そして、この貫通孔421は、接触部441の形状・大きさに応じて、設計される。   In the connector disclosed in Patent Document 1, as shown in FIG. 9 of Patent Document 1, the insulator 42 (housing) has a through hole 421 for receiving the contact portion 441 (center terminal). The through hole 421 is designed according to the shape and size of the contact portion 441.

特許文献1に記載されるような、嵌合方向に相手コネクタと逆側に貫通孔を有するコネクタでは、相手コネクタの中心端子と嵌合させると、接触部441が、相手コネクタと逆側へと変位することがある。このとき、外部シェル46の蓋465と接触部441との距離が、変動するため、蓋465と接触部441との間のインピーダンスも変動してしまい、その結果、信号の伝達特性が変わってしまうという課題があった。近年は、特に、コネクタが小型化しているため、蓋465と接触部441との間にわずかな距離の変動が発生しただけでも、信号の品質を劣化させることになる。また、接触部441の変動が大きい場合には、蓋465と接触して、短絡してしまうこともあった。本発明は、インピーダンスの特性が、安定的で、短絡が発生しにくい同軸ケーブルコネクタを提供することを目的とする。   In a connector having a through-hole on the opposite side of the mating connector in the fitting direction as described in Patent Document 1, when the center terminal of the mating connector is fitted, the contact portion 441 moves to the opposite side of the mating connector. May be displaced. At this time, since the distance between the lid 465 of the outer shell 46 and the contact portion 441 varies, the impedance between the lid 465 and the contact portion 441 also varies, and as a result, the signal transmission characteristics vary. There was a problem. In recent years, in particular, since the connector has been downsized, even if a slight change in the distance between the lid 465 and the contact portion 441 occurs, the signal quality is deteriorated. Moreover, when the fluctuation | variation of the contact part 441 is large, it may contact with the lid | cover 465 and may short-circuit. An object of the present invention is to provide a coaxial cable connector that has stable impedance characteristics and is less likely to cause a short circuit.

The outer conductor 70 is mainly provided with the housing 40 and the coaxial cable 10, an arrangement surface 85 facing the outer surface of the back surface 21 and the upper surface portion 41, and a substantially cylinder provided on the distal end side of the arrangement surface 85. Part 72 and a plurality of crimping parts 80, 83, 84. The substantially cylindrical portion 72 is a portion that has elasticity in the radial direction and is connected to and locked with an external conductor (not shown) of the mating connector when fitted with the mating connector. A substantially cylindrical portion 72 is formed on the distal end side of the arrangement surface 85 by a scoop shape as a whole, an inner surface 78 serving as a lid facing the upper surface portion 41, and a rising portion 74 which is a part constituting a spoon portion. A cover portion 73 having a structure in which the strength of the substantially cylindrical portion 72 is strengthened is formed. The substantially cylindrical portion 72 has three cutouts 71 on the distal end side and the left and right sides, and the upper surface of the fitting portion 42 is between the cutout 71 and the surface 78 of the outer conductor 70 facing the housing 40. Three protrusions 44 projecting to the left and right outside of the portion 41 are sandwiched, and the housing 40 can be fixed to the outer conductor shell 70.

カシメ部は、配置面85を挟んで対向する各側にそれぞれが配置された対を成すカシメ部として形成されている。ここでは同軸ケーブル10の延出方向(α方向)に沿って計3組、即ち、前側カシメ部80、中間カシメ部83、後側カシメ部84が設けられている。前側カシメ部80A、80Bは、主に、ハウジング40の圧着片50A、50Bを外部からかしめ、接続部24と芯線14の接続を維持するためのもの、中間カシメ部83A、Bは、主に、外部導体12をかしめるためのもの、後側カシメ部84A、Bは、主に、絶縁被覆11をかしめるためのものである。   The caulking portion is formed as a caulking portion forming a pair in which the caulking portion is arranged on each side facing each other with the arrangement surface 85 interposed therebetween. Here, a total of three sets, that is, a front caulking portion 80, an intermediate caulking portion 83, and a rear caulking portion 84 are provided along the extending direction (α direction) of the coaxial cable 10. The front caulking portions 80A and 80B are mainly used for caulking the crimping pieces 50A and 50B of the housing 40 from the outside and maintaining the connection between the connecting portion 24 and the core wire 14, and the intermediate caulking portions 83A and B are mainly used for The caulking for the outer conductor 12 and the rear caulking portions 84A and 84B are mainly for caulking the insulating coating 11.

コネクタ1は、例えば、以下の方法によって、製造される。端子20は、通常、金属平面板を打ち抜き、折り曲げることによって、成形される。図2に示されるように、背部21は、平坦であり、相手コネクタと逆側に向いた背面23を有する。一方で、接触片27は、打ち抜きされた金属板において背部21から軸線方向(α方向)に対して垂直方向両側に突出する2つの突出片を折り曲げて、成形するようにしてもよい。接触部22の接触片27は、向かい合う二枚の金属片で構成され、嵌合部42の収容部43の径方向の外側方向から内側方向に向けて延びる。この2枚の金属で構成された接触片27は、外側方向に弾性を持ち、接触片27間の距離が、相手コネクタの端子の大きさよりも小さいので、接触片27の間に挿入された相手コネクタの端子を把持することができる。また、接触片27の先端部分は、外側方向に向いているが、これは、相手コネクタの端子を2枚の金属片間に案内するためのものである。 The connector 1 is manufactured by the following method, for example. The terminal 20 is usually formed by punching and bending a metal flat plate. As shown in FIG. 2, the back portion 21 is flat and has a back surface 23 facing away from the mating connector. On the other hand, the contact piece 27 may be formed by bending two protruding pieces protruding from the back portion 21 on both sides in the direction perpendicular to the axial direction (α direction) in the punched metal plate. The contact piece 27 of the contact portion 22 is composed of two metal pieces facing each other, and extends from the radially outer side of the accommodating portion 43 of the fitting portion 42 toward the inner side. The contact piece 27 composed of the two metal pieces has elasticity in the outer direction, and the distance between the contact pieces 27 is smaller than the size of the terminal of the mating connector, so that the contact piece 27 is inserted between the contact pieces 27. The terminal of the mating connector can be gripped. Further, the tip end portion of the contact piece 27 faces outward, which is for guiding the terminal of the mating connector between the two metal pieces.

ハウジング40は、樹脂モールドによって、折り曲げ成形された端子20と一体成形して作られる。ただし、端子20の一部は、一体成形後も外部に露出したままである。端子20の露出部には、ケーブルの芯線と接続する接続部24の先端部分及び、相手コネクタの端子と接続する接触部22の接触片27が含まれる。しかし、これらの部分の周囲など他の部分が露出していてもよい。   The housing 40 is formed by integral molding with the bent terminal 20 by a resin mold. However, a part of the terminal 20 remains exposed even after integral molding. The exposed portion of the terminal 20 includes a distal end portion of the connection portion 24 connected to the cable core and a contact piece 27 of the contact portion 22 connected to the terminal of the mating connector. However, other parts such as the periphery of these parts may be exposed.

端子20とハウジング40を一体成形した後に、端子20に対して、メッキ処理を行う。メッキ処理は、例えば、端子20の腐食を防止するために用いられる。また、相手コネクタとの着脱の際に、相手コネクタの端子と接触して、端子20の表面に摩耗が生じるが、この摩耗から端子20を保護するためにも、端子20の表面にはメッキ処理が施される。メッキの材料には、例えば、ニッケルや、金が用いられる。また、複数の種類の材料を用いて、繰り返しメッキを行い、複数層を持つメッキを施すこともある。   After the terminal 20 and the housing 40 are integrally formed, the terminal 20 is plated. The plating process is used, for example, to prevent corrosion of the terminal 20. Further, when the connector is attached to or detached from the mating connector, the surface of the terminal 20 is worn by contact with the terminal of the mating connector. To protect the terminal 20 from this wear, the surface of the terminal 20 is plated. Is given. For example, nickel or gold is used as a plating material. In addition, a plurality of types of materials may be used for repeated plating, and plating having a plurality of layers may be performed.

メッキ処理の方法には、様々な方法があり、本発明では、いずれの方法もコネクタのメッキ処理に用いることが可能な限り、排斥するものではない。メッキ処理の方法の一例としては、ハウジング40と一体成形された端子に対して、メッキ材料を塗布し電気メッキする方法が挙げられる。また、液体化したメッキ材料を容器に溜めて、端子20をメッキ浴内に浸漬させる方法を用いてもよい。メッキは、樹脂で作成されたハウジング40の表面には、付着しないため、ハウジング40を端子20に一体成形した後に、メッキ処理を行うと、立体形状の接触部22がハウジングの収容部43内に保護されて取扱いが容易であると共に、ハウジング40によって覆われた端子20の表面には、メッキ処理が行われないので、端子20の非露出部分の表面積だけ、メッキ材料の使用量を減らすことができ、コネクタの製造費用を低下させることができる。   There are various plating methods. In the present invention, any method is not excluded as long as it can be used for connector plating. As an example of the plating method, a method in which a plating material is applied to a terminal integrally formed with the housing 40 and electroplating is exemplified. Alternatively, a method may be used in which the liquefied plating material is stored in a container and the terminal 20 is immersed in the plating bath. Since plating does not adhere to the surface of the housing 40 made of resin, when the plating process is performed after the housing 40 is integrally formed with the terminal 20, the three-dimensional contact portion 22 is placed in the housing accommodating portion 43. Since it is protected and easy to handle and the surface of the terminal 20 covered by the housing 40 is not plated, the amount of plating material used can be reduced by the surface area of the unexposed portion of the terminal 20. This can reduce the manufacturing cost of the connector.

嵌合部42の上面部41には、貫通孔48が形成されている。この貫通孔48は、ハウジング40と端子20を一体成形した後にメッキ処理を行う場合に特に有効である。接続部24のような平面部分は、ハウジング40と一体成形した後であってもメッキを行うことは、容易であるが、接触部22は、嵌合部42に囲まれている上に立体的形状を有するので、接触部22に、メッキを接触部22の全体に施すことは、容易ではない。図3のAA切断面における断面図である図5から理解できるように接触片27が、背部21と接続する折り曲げ位置から、外側方向へと膨らみ、内側へと延びるという湾曲した形状を持つことから、相手コネクタ側から見ると、接触片27の嵌合部42の上面部41側に影になる面27’が存在する。貫通孔48が存在しない場合には、このような影になる面27’では、メッキ液の流動が困難である、あるいは、メッキ浴に浸漬させた際に空気が溜まる等の理由により、メッキ処理が十分に施されないことがある。しかし、貫通孔48が、嵌合部42の上面部41に存在することにより、嵌合方向の相手コネクタとは、逆側からメッキを塗布することも可能であるし、メッキ浴に浸漬させた場合にも空気が溜まりにくくなる。そのため、貫通孔48により、接触片27全体にメッキが行き渡りやすくなる。貫通孔48は、接触部22の背部21の上側平坦面である背面23にのみ位置する場合には、背面23によって貫通孔48がふさがれてしまい、メッキが、接触片27全体に行き渡る効果が得られないため、貫通孔48は、収容部43と連通させる必要がある。特に、嵌合方向から見て貫通孔48の面積は、接触部22の面積よりも大きい場合には、メッキを塗布しやすいため、好ましい。   A through hole 48 is formed in the upper surface portion 41 of the fitting portion 42. This through hole 48 is particularly effective when the plating process is performed after the housing 40 and the terminal 20 are integrally formed. The flat portion such as the connecting portion 24 can be easily plated even after being integrally formed with the housing 40, but the contact portion 22 is surrounded by the fitting portion 42 and is three-dimensional. Since it has a shape, it is not easy to apply plating to the entire contact portion 22 on the contact portion 22. As can be understood from FIG. 5, which is a cross-sectional view taken along the AA section of FIG. 3, the contact piece 27 has a curved shape that bulges outward from the bending position where it connects with the back portion 21 and extends inward. When seen from the mating connector side, a shadowed surface 27 ′ is present on the upper surface 41 side of the fitting portion 42 of the contact piece 27. In the case where the through hole 48 does not exist, the plating process is performed on the shadowed surface 27 ′ because the plating solution is difficult to flow or air is accumulated when immersed in the plating bath. May not be adequately applied. However, since the through-hole 48 exists in the upper surface portion 41 of the fitting portion 42, it is possible to apply plating from the opposite side to the mating connector in the fitting direction, and it is immersed in a plating bath. Even in this case, it becomes difficult for air to collect. Therefore, the plating easily spreads over the entire contact piece 27 by the through hole 48. When the through hole 48 is located only on the back surface 23, which is the upper flat surface of the back portion 21 of the contact portion 22, the through hole 48 is blocked by the back surface 23, and the plating spreads over the entire contact piece 27. Since it cannot be obtained, the through hole 48 needs to communicate with the accommodating portion 43. In particular, when the area of the through-hole 48 is larger than the area of the contact portion 22 when viewed from the fitting direction, it is preferable because plating is easily applied.

本実施形態においては、上面部41には、背部21の背面23と外部導体70の内面78の間に、貫通孔48の内面から逆側の内面まで背部21の背面23に沿って延出し、接触部22の背面23に接触して、支持する支持部49が、形成されている。本実施形態は、高さが0.6mmである小型コネクタゆえに端子20の背面23と外部導体70の内面78が0.1mm以下に近接しているが、支持部49は、背部21が、相手コネクタとの着脱による相手コネクタと逆側への変位を防いで、背部21と外部導体70の蓋部73の間の距離を一定に保ち、高周波信号を流す同軸コネクタとしてのインピーダンスを維持することができる。また、支持部49が存在することにより、接触部22が、外部導体70の対向する面78と電気的に短絡することや、折れ曲がることを防ぐこともできる。メッキ処理を行う際に、嵌合部42の上面部41が、貫通孔48を有すると共に、支持部49を有することにより、ハウジング40と一体成形した後に、端子20にメッキ処理を行っても実用性を有するコネクタが製造されることになる。   In the present embodiment, the upper surface portion 41 extends between the back surface 23 of the back portion 21 and the inner surface 78 of the outer conductor 70 along the back surface 23 of the back portion 21 from the inner surface of the through hole 48 to the inner surface on the opposite side. A support portion 49 is formed in contact with and supporting the back surface 23 of the contact portion 22. In the present embodiment, since the height of the small connector is 0.6 mm, the back surface 23 of the terminal 20 and the inner surface 78 of the external conductor 70 are close to 0.1 mm or less. Displacement to the opposite side of the mating connector due to the attachment / detachment with the connector is prevented, the distance between the back portion 21 and the lid portion 73 of the external conductor 70 is kept constant, and the impedance as a coaxial connector through which a high-frequency signal flows can be maintained. it can. In addition, the presence of the support portion 49 can prevent the contact portion 22 from being electrically short-circuited with the opposing surface 78 of the outer conductor 70 or bent. When the plating process is performed, the upper surface part 41 of the fitting part 42 has the through hole 48 and the support part 49 so that the terminal 20 can be practically used after being molded integrally with the housing 40. A connector having the characteristics will be manufactured.

図5を見ると、上面部41と筒部47の接続部分の高さに、嵌合方向の上面部側に向いて背面23の高さと同じ位置に段差部51が存在することがわかる。この段差部51は、貫通孔48の外周が、筒部47の内周よりも大きいことによって、形成される。ハウジング40と端子20の一体成形は、2分割された金型が、嵌合方向の両側から、端子20を挟み込むようにして取り付けられて樹脂流入部分と隔絶した上で、金型内部に樹脂モールドを流し込むことによって行われる。段差部51が存在することによって、中実状の上面部41側の金型が、中空状の筒部47側の金型よりも幅方向に大きいため、上部金型の一端が背面23の縁を押さえながら、蓋をするように塞いで上下の金型の位置合わせを容易に行うことができる。別の実施形態において上下金型の中実状と中空状を入れ替える場合には、貫通孔48の外周を、筒部47の内周よりも小さくすることによって、上面部41の一部として、嵌合方向の相手コネクタ側に向いた面を持つ段部を形成しても同様の目的を達することが可能である。   When FIG. 5 is seen, it turns out that the level | step-difference part 51 exists in the height of the connection part of the upper surface part 41 and the cylinder part 47 in the same position as the height of the back surface 23 toward the upper surface part side of a fitting direction. The step portion 51 is formed by the outer periphery of the through hole 48 being larger than the inner periphery of the tube portion 47. The housing 40 and the terminal 20 are integrally molded by attaching the mold divided into two from both sides in the fitting direction so as to sandwich the terminal 20 and separating from the resin inflow portion. Is done by pouring. Since the stepped portion 51 is present, the solid mold on the upper surface portion 41 side is larger in the width direction than the mold on the hollow cylindrical portion 47 side, so that one end of the upper mold has the edge of the back surface 23. While holding down, the upper and lower molds can be easily aligned by closing the cover like a lid. In another embodiment, when the solid shape and the hollow shape of the upper and lower molds are interchanged, the outer periphery of the through hole 48 is made smaller than the inner periphery of the cylindrical portion 47, so that the fitting is performed as a part of the upper surface portion 41. A similar purpose can be achieved by forming a step portion having a surface facing the mating connector side.

メッキ処理の後には、端子20の表面にメッキされず残存したメッキ材料及びその他の塵などを流すための洗浄処理を行う。洗浄処理において、嵌合方向相手コネクタ側からみて、影となる部分が、洗浄しにくいことは、メッキ処理と同様であるが、貫通孔48が設けられていることにより、洗浄を十分に行うことが容易になる。また、貫通孔48を設けないと洗浄液の十分な排出が困難となってしまい、洗浄処理後も、洗浄液が、影となる面27’と上面部41の間等に残ってしまうことがある。   After the plating process, a cleaning process is performed to flow the plating material remaining on the surface of the terminal 20 and other dust. In the cleaning process, it is the same as the plating process that the shadowed portion is difficult to clean when viewed from the mating connector of the mating direction, but the cleaning is sufficiently performed by providing the through hole 48. Becomes easier. Further, if the through hole 48 is not provided, it is difficult to sufficiently discharge the cleaning liquid, and the cleaning liquid may remain between the shadowed surface 27 ′ and the upper surface portion 41 after the cleaning process.

軸線方向から見た断面を示す図5から理解されるように、本実施形態では、背面23の幅が支持部49の幅よりも僅かに大きいが、別の実施形態では、背面23の幅や長さが、支持部の幅や長さよりも大きくてもよい。支持部が、背面23の一部のみでも支持すれば、相手コネクタとの着脱やメッキ等による、接触部22にかかる圧力に対して抗する効果を得るが可能だからである。また、背面23の幅が、支持部の幅よりも大きい場合には、接触部22の上部側に、樹脂モールドではなく、空気が存在することになる。樹脂モールドが、空気と比べて高い誘電率を持っていることにより、特に高周波信号を流す場合に、電気的性能を低下させることになる。すなわち、背面23上にある支持部の面積を低下させることによって、電気的性能を向上させることができる。したがって、背面23の幅よりも細い幅の支持部を採用することにより、接触部22の折れ曲がりを防止等することによる耐久性の向上と、電気的性能の向上を両立させることができる。   As can be understood from FIG. 5 showing a cross section viewed from the axial direction, in the present embodiment, the width of the back surface 23 is slightly larger than the width of the support portion 49, but in another embodiment, The length may be larger than the width or length of the support portion. This is because if the support portion supports only a part of the back surface 23, it is possible to obtain an effect that resists the pressure applied to the contact portion 22 due to attachment / detachment with the mating connector, plating, or the like. Moreover, when the width | variety of the back surface 23 is larger than the width | variety of a support part, air will exist in the upper part side of the contact part 22 instead of a resin mold. Since the resin mold has a higher dielectric constant than air, the electrical performance is deteriorated particularly when a high-frequency signal flows. That is, the electrical performance can be improved by reducing the area of the support portion on the back surface 23. Therefore, by adopting a support portion having a width smaller than the width of the back surface 23, it is possible to achieve both improvement in durability and prevention of bending of the contact portion 22 and improvement in electrical performance.

図6に、本発明の他の実施形態の上面部側から見た斜視図を示す。本実施形態においては、貫通孔48の内壁のケーブル側と、ケーブル側の逆側の両側から支持部49’が、背面23に沿って、内側に突出しているが両支持部は、連結していないことにより、背面23上に位置する支持部49’の量を減らしつつ、背面23を支持することができるので、接触部22の耐久性の向上と、コネクタの電気的性能の向上を両立させることが可能なる。 In FIG. 6, the perspective view seen from the upper surface part side of other embodiment of this invention is shown. In the present embodiment, the support portion 49 ′ protrudes inward along the back surface 23 from both the cable side of the inner wall of the through hole 48 and the opposite side of the cable side, but both the support portions are connected. Since the back surface 23 can be supported while reducing the amount of the support portion 49 ′ located on the back surface 23, both the durability of the contact portion 22 and the electrical performance of the connector are improved. it becomes possible.

本発明は、上述した実施の形態に限定されるわけではなく、貫通孔48の内面のケーブル側又はケーブル側と逆側の一方のみから背面23に沿って支持部が突出する実施形態や、支持部が、貫通孔48の内壁とつながっておらず、背面23上に島状に形成されるなど、種々の変更が可能であることは勿論である。従って、本発明の請求項の範囲には、当業者が通常行う種々の変形例が含まれる。   The present invention is not limited to the above-described embodiment, and an embodiment in which the support portion protrudes along the back surface 23 from only one of the inner surface of the through hole 48 on the cable side or the cable side and the opposite side, It goes without saying that various changes are possible, for example, the portion is not connected to the inner wall of the through hole 48 and is formed in an island shape on the back surface 23. Accordingly, the scope of the claims of the present invention includes various modifications usually made by those skilled in the art.
