Description

コネクタの実装構造Connector mounting structure
　本発明は、プリント配線基板にコネクタを実装するコネクタの実装構造に関し、更に詳しくは、外部コンタクトと中心コンタクトを有するコネクタをプリント配線基板の平面に沿って移動自在に実装するコネクタの実装構造に関する。 The present invention relates to a connector mounting structure for mounting a connector on a printed wiring board, and more particularly to a connector mounting structure for mounting a connector having external contacts and a center contact movably along a plane of the printed wiring board.
　プリント配線基板や筐体に取付けられるコネクタは、コネクタの取付誤差や組み立て誤差が生じると、相手側コネクタとの嵌合接続に位置ずれが生じたり、筐体の貫通孔との位置ずれが生じてコネクタの接続部を貫通孔から突出できないといった問題が生じ、従来のコネクタには、これらの取付誤差や組み立て誤差を吸収するために、固定側のプリント配線基板や筐体に対してコネクタを一定範囲で可動自在に取付けるいわゆるフローティング構造が採用されている。 When a connector attached to a printed wiring board or a housing has a mounting error or an assembly error, the mating connection with the mating connector may be misaligned or misaligned with the through hole of the housing. There is a problem that the connector connection portion can not protrude from the through hole, and the conventional connector has a certain range of the connector relative to the fixed printed wiring board and the housing in order to absorb these mounting errors and assembly errors. A so-called floating structure is adopted which is movably mounted.
　図６は、筐体１０１の貫通孔１０１ａを貫通するコネクタ１００が、相手側コネクタ２００に合わせて筐体１０１に沿って可動する特許文献１に記載のフローティング構造を示している。コネクタ１００は、中心コンタクト１０２の周囲にインシュレータ１０３を介して同軸上に円筒状の外部コンタクト１０４が取付けられた同軸コネクタであり、図において右方から相手側コネクタ２００が嵌合接続することによって、中心コンタクト１０２と外部コンタクト１０４に相手側コネクタ２００の中心ピン２０１と外部導体２０２がそれぞれ電気接続する。 FIG. 6 shows a floating structure described in Patent Document 1 in which the connector 100 penetrating the through hole 101 a of the housing 101 is movable along the housing 101 in accordance with the mating connector 200. The connector 100 is a coaxial connector in which a cylindrical external contact 104 is coaxially attached around the center contact 102 via an insulator 103, and the mating connector 200 is fitted and connected from the right in the figure, The center pin 201 and the external conductor 202 of the mating connector 200 are electrically connected to the center contact 102 and the external contact 104, respectively.
　コネクタ１００の周囲には、筐体１０１の表面に沿って配置されるフランジ部１０５が一体に形成され、フランジ部１０５の長孔１０６を挿通させた固定ネジ１０７を筐体１０１にネジ止めしてコネクタ１００を筐体１０１に取付けている。フランジ部１０５の長孔１０６の内径は、固定ネジ１０７の軸部１０７ａの外径より長く、従って、軸部１０７ａが長孔１０６内で相対移動する移動範囲で、コネクタ１００は筐体１０１の表面に沿って移動自在で、更に筐体１０１の貫通孔１０１ａもコネクタ１００を游挿させる十分な大きさとなっているので、コネクタ１００の全体は、相手側コネクタ２００の嵌合接続位置に一致するように筐体１０１に対して移動する。 A flange portion 105 disposed along the surface of the housing 101 is integrally formed around the connector 100, and the fixing screw 107 inserted through the long hole 106 of the flange portion 105 is screwed to the housing 101. The connector 100 is attached to the housing 101. The inner diameter of the long hole 106 of the flange portion 105 is longer than the outer diameter of the shaft portion 107 a of the fixing screw 107, so the connector 100 is a surface of the housing 101 within a movement range where the shaft portion 107 a moves relatively in the long hole 106. Since the through hole 101a of the housing 101 is also large enough to allow insertion of the connector 100, the whole of the connector 100 coincides with the mating connection position of the mating connector 200. Move relative to the housing 101.
　図７は、筐体１１１に対して一部が筐体１１１の平面に沿って可動する他のフローティング構造を備えた特許文献２に記載された同軸コネクタ１１０であり、この同軸コネクタ１１０は、筐体１１１に対して筒状可動シェル１１２が可動すると共に同軸コネクタ１１０が貫通する筐体１１１の貫通孔１１１ａに筒状可動シェル１１２を可動させるための隙間があっても、筐体１１１内を機密に保持する防水構造が備えられている。 FIG. 7 shows a coaxial connector 110 described in Patent Document 2 having another floating structure which is partially movable along the plane of the housing 111 with respect to the housing 111, and the coaxial connector 110 is a housing Even if there is a gap for moving the cylindrical movable shell 112 in the through hole 111 a of the housing 111 in which the cylindrical movable shell 112 is movable with respect to the body 111 and the coaxial connector 110 penetrates, the inside of the housing 111 is classified. It is equipped with a waterproof structure to hold on.
　同軸コネクタ１１０は、筐体１１１に対して固定して取り付けられる筒状外部シェル１１３と、筒状外部シェル１１３に対して可動自在に取り付けられる筒状可動シェル１１２と、筒状可動シェル１１２内にインシュレータ１１４を介してその中心軸に沿って取り付けられる中心コンタクト１１５を備えている。従って、他の機器に取り付けられた相手側コネクタ２１０との位置ずれがあっても、相手側コネクタ２１０と嵌合接続する筒状可動シェル１１２が筐体１１１に対して位置ずれした方向に移動し、筒状可動シェル１１２と中心コンタクト１１５が相手側コネクタ２１０に嵌合接続する。 The coaxial connector 110 includes a cylindrical outer shell 113 fixedly attached to the housing 111, a cylindrical movable shell 112 movably attached to the cylindrical outer shell 113, and a cylindrical movable shell 112. A central contact 115 is mounted along the central axis via an insulator 114. Therefore, even if there is a positional deviation from the mating connector 210 attached to another device, the cylindrical movable shell 112 fitted and connected to the mating connector 210 moves in the direction displaced relative to the housing 111. The cylindrical movable shell 112 and the center contact 115 are fitted and connected to the mating connector 210.
　筐体１１１の貫通孔１１１ａの周囲と筒状外部シェル１１３及び筒状外部シェル１１３と相対移動する筒状可動シェル１１２の間には、それぞれ防水リング１１６、１１７が圧縮した状態で配置されるので、図中左方の筐体１１１内は外部と遮断された気密状態に保持される。 The waterproof rings 116 and 117 are disposed in a compressed state, respectively, around the through hole 111 a of the housing 111 and between the cylindrical outer shell 113 and the cylindrical movable shell 112 that moves relative to the cylindrical outer shell 113. The inside of the housing 111 on the left side in the drawing is kept in an airtight state that is shut off from the outside.

　上述の従来のフローティング構造を備えたコネクタ１００、１１０は、相手側コネクタ２００、２１０との接続位置ずれを吸収するために筐体１０１、１１１に対して移動自在に取り付けられるものであるが、例えば、コネクタ１００、１１０が筐体１０１、１１１内に取り付けられるプリント配線基板に実装される基板用コネクタである場合にも、筐体１０１、１１１とプリント配線基板との取り付け誤差を吸収するために、同様にコネクタ１００，１１０を筐体１０１、１１１に対して可動させる必要があり、コネクタ１００、１１０を貫通させる貫通孔１０１ａ、１１１ａに、コネクタ１００、１１０を移動自在とする隙間を設けなければならない。 The connectors 100 and 110 having the above-described conventional floating structure are movably attached to the housings 101 and 111 in order to absorb connection positional deviation with the mating connectors 200 and 210, for example. Even in the case where the connectors 100 and 110 are board connectors mounted on a printed wiring board mounted in the housings 101 and 111, in order to absorb mounting errors between the housings 101 and 111 and the printed wiring board, Similarly, it is necessary to move the connectors 100 and 110 relative to the housings 101 and 111, and in the through holes 101a and 111a for passing the connectors 100 and 110, gaps must be provided to make the connectors 100 and 110 movable. .
　そのために、貫通孔１０１ａ、１１１ａとコネクタ１００、１１０の間に十分な大きさの隙間を形成され、特許文献１に記載のコネクタ１００では、筐体１０１内を気密にして防水構造とすることができない。 Therefore, a gap of a sufficient size is formed between the through holes 101a and 111a and the connectors 100 and 110, and in the connector 100 described in Patent Document 1, the inside of the housing 101 is made airtight to form a waterproof structure. Can not.
　また、コネクタ１００のフローティング構造は、固定ネジ１０７の軸部１０７ａとフランジ部１０５の長孔１０６の隙間でコネクタ１００を移動させるものであることから、長孔１０６の長手方向に沿った方向でしかコネクタ１００を可動させることができない。長孔１０６を円形孔として筐体１０１の平面に沿った全方向に可動させることも可能であるが、円形孔の内径は、固定ネジ１０７の頭部１０７ｂの外径より長くすることができないので、その移動範囲が限られ、実装誤差や取り付け誤差や大きい場合には、その誤差を吸収できない。 Further, since the floating structure of the connector 100 is to move the connector 100 in the gap between the shaft portion 107 a of the fixing screw 107 and the long hole 106 of the flange portion 105, it is only in the direction along the long hole 106. The connector 100 can not be moved. Although it is possible to move the long hole 106 as a circular hole in all directions along the plane of the housing 101, the inner diameter of the circular hole can not be made longer than the outer diameter of the head 107b of the fixing screw 107. The movement range is limited, and if the mounting error or the mounting error is large, the error can not be absorbed.
　一方、特許文献２に記載のコネクタ１１０によれば、筐体１１１の貫通孔１１１ａと筒状可動シェル１１２の間に隙間があっても、筐体１１１に密着して固定される筒状外部シェル１１３を介して筒状可動シェル１１２が可動自在に取り付けられているので、筐体１１１内を防水構造とすることができるが、少なくとも筐体１１１と筒状外部シェル１１３間、及び筒状外部シェル１１３と筒状可動シェル１１２間の２カ所に防水リングを密着して配置させる必要があり、防水構造が複雑となる。 On the other hand, according to the connector 110 described in Patent Document 2, even if there is a gap between the through hole 111a of the housing 111 and the cylindrical movable shell 112, the cylindrical outer shell is closely fixed to the housing 111 and fixed. Since the cylindrical movable shell 112 is movably attached via 113, the inside of the housing 111 can be made waterproof, but at least between the housing 111 and the cylindrical outer shell 113, and the cylindrical outer shell It is necessary to closely arrange the waterproof ring in two places between 113 and the cylindrical movable shell 112, and the waterproof structure becomes complicated.
　更に、コネクタ１１０自体も、少なくとも筒状可動シェル１１２と筒状外部シェル１１３の２部品で構成する必要があり、２分割した筒状可動シェル１１２の間に筒状外部シェル１１３を挟持して、筒状外部シェル１１３に対して筒状可動シェル１１２を可動自在に取り付けるので、部品点数が増加し、その構造も複雑なものとなっていた。 Furthermore, the connector 110 itself needs to be constituted by at least two parts of the cylindrical movable shell 112 and the cylindrical outer shell 113, and the cylindrical outer shell 113 is held between the two divided cylindrical movable shells 112, Since the cylindrical movable shell 112 is movably attached to the cylindrical outer shell 113, the number of parts is increased, and the structure is also complicated.
　本発明は、このような従来の問題点を考慮してなされたものであり、コネクタの一部に可動部分を設けない簡単な構造で、プリント配線基板の平面に沿って移動可能にコネクタを実装できるコネクタの実装構造を提供することを目的とする。 The present invention has been made in view of such conventional problems, and has a simple structure in which a movable portion is not provided in a part of the connector, and the connector is mounted movably along the plane of the printed wiring board It is an object of the present invention to provide a connector mounting structure that can
　また、筐体内に取り付けられるプリント配線基板へ実装するコネクタを、筐体に対して移動自在とすることができるコネクタの実装構造を提供することを目的とする。 Another object of the present invention is to provide a connector mounting structure that can move a connector mounted on a printed wiring board mounted in a housing relative to the housing.
　また、相手側コネクタとの接続のためにコネクタを臨ませる筐体の窓孔を、筐体に対して移動自在のコネクタの外径にほぼ等しい内径として、窓孔とコネクタ間に隙間が生じないコネクタの実装構造を提供することを目的とする。 Also, no gap is created between the window hole and the connector, with the window hole of the case facing the connector for connection with the mating connector being an inner diameter substantially equal to the outer diameter of the movable connector relative to the case It aims at providing the mounting structure of a connector.
　上述の目的を達成するため、請求項１に記載のコネクタの実装構造は、相手側コネクタと嵌合接続し、相手側コネクタの外部接続部に接触する外部コンタクトと、相手側コネクタの中心接続部に接触する中心コンタクトと、外部コンタクトと中心コンタクトを互いに絶縁して支持するインシュレータとを有するコネクタと、外部コンタクトに電気接続する外部端子と、中心コンタクトに電気接続する中心端子とを備え、外部端子と中心端子を、それぞれプリント配線基板の対応する導電パターンに半田接続し、プリント配線基板へコネクタを実装するコネクタの実装構造であって、
　コネクタの外部端子と中心端子の周囲に、それぞれ外部端子と中心端子をプリント配線基板の平面に沿った所定の移動範囲で相対移動自在とする相対移動空隙を形成し、外部端子が前記移動範囲で相対移動する間に外部コンタクトと常時電気接続する第１導電接続体を、外部端子と外部コンタクトの間に配設するとともに、中心端子が前記移動範囲で相対移動する間に中心コンタクトとを常時電気接続する第２導電接続体を、中心端子と中心コンタクトの間に配設し、外部コンタクトと中心コンタクトをそれぞれプリント配線基板の対応する導電パターンに電気接続させた状態で、コネクタをプリント配線基板の平面に沿った前記移動範囲で移動自在にプリント配線基板へ実装することを特徴とする。 In order to achieve the above-mentioned object, the connector mounting structure according to claim 1 is connected with the mating connector, and the external contact contacting the external connection portion of the mating connector and the central connection portion of the mating connector An external terminal electrically connected to the external contact, and a central terminal electrically connected to the central contact. And mounting the connector on the printed wiring board by soldering the center terminal and the corresponding center terminal to the corresponding conductive pattern of the printed wiring board,
A relative movement air gap is formed around the external terminal and the center terminal of the connector so that the external terminal and the center terminal can be moved relative to each other within a predetermined movement range along the plane of the printed wiring board. A first conductive connector, which is always in electrical contact with the external contact during relative movement, is disposed between the external terminal and the external contact, and the central contact is constantly electrically connected with the central contact while relative movement in the movement range. The second conductive connector to be connected is disposed between the center terminal and the center contact, and the connector is formed on the printed wiring board with the external contact and the center contact electrically connected to the corresponding conductive patterns of the printed wiring board. It mounts on a printed wiring board movably in the said movement range along a plane.
　コネクタの外部端子と中心端子の周囲に、それぞれ外部端子と中心端子をプリント配線基板の平面に沿った所定の移動範囲で相対移動自在とする相対移動空隙が形成されることにより、コネクタは、プリント配線基板の対応する導電パターンに半田接続する外部端子及び中心端子と干渉することなく、プリント配線基板の平面に沿った所定の移動範囲で相対移動自在となる。コネクタがプリント配線基板に対していずれの移動位置にあっても、外部端子と外部コンタクト間は第１導電接続体によって、中心端子と中心コンタクト間は第２導電接続体によって電気接続しているので、コネクタは、プリント配線基板の導電パターンに電気接続した状態でプリント配線基板に対して移動自在に実装される。 The connector is printed by forming a relative movement gap around the outer terminal and the center terminal of the connector such that the outer terminal and the center terminal can be relatively moved within a predetermined movement range along the plane of the printed wiring board. Relative movement is possible within a predetermined movement range along the plane of the printed wiring board without interfering with the external terminal and the center terminal soldered to the corresponding conductive pattern of the wiring board. Since the external terminal and the external contact are electrically connected by the first conductive connector and the central terminal and the central contact are electrically connected by the second conductive connector regardless of the movement position of the connector with respect to the printed wiring board The connector is movably mounted on the printed wiring board in a state of being electrically connected to the conductive pattern of the printed wiring board.
　請求項２に記載のコネクタの実装構造は、コネクタが、中心コンタクトの軸周りにインシュレータを介して外部コンタクトを同軸状に配置した同軸コネクタであり、
　前記プリント配線基板が一体に固定された筐体の窓孔に臨み、相手側コネクタと嵌合接続することを特徴とする The connector mounting structure according to claim 2, wherein the connector is a coaxial connector in which external contacts are coaxially arranged via an insulator around an axis of the central contact,
The printed wiring board faces the window hole of the housing integrally fixed, and is fitted and connected with the mating connector.
　コネクタの形状や構造を変更することなく、プリント配線基板に対して移動自在とするので、同軸コネクタの特性インピーダンスが変化しない。 The characteristic impedance of the coaxial connector does not change because the connector can be moved relative to the printed wiring board without changing the shape or the structure of the connector.
　プリント配線基板の平面に沿ってコネクタを移動自在に実装できるので、プリント配線基板が筐体に固定されている場合であっても、筐体の窓孔の位置に合わせてコネクタを移動させて窓孔へ臨ませることができる。 Since the connector can be mounted movably along the plane of the printed wiring board, even when the printed wiring board is fixed to the housing, the connector is moved according to the position of the window hole of the housing and the window You can make it to the hole.

　以下、本発明の一実施の形態に係るコネクタの実装構造１を、図１乃至図４を用いて説明する。本明細書では、コネクタ１０をプリント配線基板３０へ実装する実装方向を下方と（図１において下方）、コネクタ１０の図示しない相手側コネクタとの接続方向を上方（図１において上方）としてコネクタの実装構造１の各部について説明する。 Hereinafter, the connector mounting structure 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4. In this specification, the mounting direction for mounting the connector 10 on the printed wiring board 30 is the bottom (in FIG. 1) and the connection direction with the mating connector (not shown) of the connector 10 is the top (upper in FIG. 1). Each part of the mounting structure 1 will be described.
　コネクタの実装構造１は、中心コンタクト２の軸周りにインシュレータ３を介して外部コンタクト４が一体に取り付けられた雄型の同軸コネクタ１０と、中心コンタクト２をプリント配線基板３０の対応する導電パターンへ電気接続する中心端子５と、外部コンタクト４を２カ所の位置でプリント配線基板３０の対応する導電パターンへ電気接続する２本の外部端子６、６とを備えている。 In the connector mounting structure 1, the male coaxial connector 10 in which the external contacts 4 are integrally attached around the axis of the center contact 2 via the insulator 3, and the center contact 2 to the corresponding conductive pattern of the printed wiring board 30 A central terminal 5 for electrical connection and two external terminals 6 for electrically connecting the external contacts 4 to corresponding conductive patterns of the printed wiring board 30 at two positions are provided.
　中心コンタクト２は、ニードル状に形成され、相手側コネクタの中心接続部に接触して接続する中心ピン７と、中心ピン７の下方に一体に連結され、下方に開口する有蓋円筒状の中心端子受部８とからなり、絶縁合成樹脂を円柱状に形成したインシュレータ３の中心孔に下方から中心ピン７を圧入してインシュレータ３に一体に組み付けられる。 The central contact 2 is formed in a needle shape and is integrally connected with the central pin 7 contacting with and connected to the central connecting portion of the mating connector and the lower portion of the central pin 7 and a cylindrical central terminal with a lid open. The center pin 7 is press-fit from below into the center hole of the insulator 3 which is made of the receiving portion 8 and in which the insulating synthetic resin is formed in a cylindrical shape, and is integrally assembled to the insulator 3.
　外部コンタクト４は、中心ピン７と一定の間隔を隔ててインシュレータ３の周囲に取り付けられ、相手側コネクタの外部接続部に嵌合接続する筒状外部シェル９と、筒状外部シェル９の下方から、中心端子受部８と一定の絶縁間隔を隔てて中心端子受部８の両側に突出する一対のフランジ部１１とが、導電性金属材料から一体に形成されている。中心コンタクト２が取り付けられたインシュレータ３は、下方から筒状外部シェル９内に圧入して外部コンタクト４に一体に組み付けられる。 The external contact 4 is attached to the periphery of the insulator 3 at a constant distance from the center pin 7 and from the lower side of the cylindrical outer shell 9 and the cylindrical outer shell 9 fitted and connected to the external connection portion of the mating connector. The center terminal receiving portion 8 and a pair of flange portions 11 projecting on both sides of the center terminal receiving portion 8 with a predetermined insulation distance are integrally formed of a conductive metal material. The insulator 3 to which the central contact 2 is attached is press-fit from below into the cylindrical outer shell 9 and integrally assembled to the external contact 4.
　一対のフランジ部１１には、それぞれフランジ部１１の平面から底面に上下に貫通する貫通孔１２が穿設されている。各貫通孔１２の平面側の開口近傍の内径は、図１に示すように、貫通孔１２を貫通する外部端子６の軸部６ａの外径より十分に長く、従って、貫通孔１２は、外部端子６をプリント配線基板３０と平行な水平方向に相対移動自在とする相対移動空隙となっている。この貫通孔１２の平面側開口近傍の内径は、その下方より小径となっていて、これにより貫通孔１２の平面側の開口近傍に、後述する外部側コイルスプリング１３の大径部１３ａを受ける下向き段部１４がリング状に形成されている。 Through holes 12 are formed in the pair of flanges 11 so as to penetrate vertically from the plane of the flanges 11 to the bottom. The inner diameter in the vicinity of the opening on the plane side of each through hole 12 is sufficiently longer than the outer diameter of the shaft portion 6a of the external terminal 6 passing through the through hole 12, as shown in FIG. It is a relative movement gap that allows relative movement of the terminals 6 in the horizontal direction parallel to the printed wiring board 30. The inner diameter in the vicinity of the flat side opening of the through hole 12 is smaller in diameter than the lower side thereof, thereby receiving the large diameter portion 13a of the outer side coil spring 13 described later in the vicinity of the flat side opening of the through hole 12 The step 14 is formed in a ring shape.
　一対の貫通孔１２、１２にそれぞれ貫通する外部端子６は、貫通孔１２の平面側開口の内径より長い直径の円板状の鍔部６ｂと、鍔部６ｂの底面側の中心から下方に垂設された軸部６ａとが導電性金属材料で一体に形成され、鍔部６ｂが貫通孔１２の周囲のフランジ部１１の平面に当接して下方に対して抜け止めされている。軸部６ａの長さは、フランジ部１１とプリント配線基板３０の厚みを加えた長さより長く、その下端は、同軸コネクタ１０をプリント配線基板３０上に配置した状態で、プリント配線基板３０の背面側に突出し、背面に沿って配線される導体パターンに半田接続される。 The external terminals 6 passing through the pair of through holes 12, 12 respectively extend downward from the center of the bottom side of the disc-like flange 6b having a diameter longer than the inner diameter of the flat side opening of the through hole 12 The shaft 6a provided is integrally formed of a conductive metal material, and the flange 6b abuts against the flat surface of the flange 11 around the through hole 12 and is prevented from coming off downward. The length of the shaft portion 6a is longer than the length obtained by adding the thicknesses of the flange portion 11 and the printed wiring board 30, and the lower end thereof is the back surface of the printed wiring board 30 with the coaxial connector 10 arranged on the printed wiring board 30. It is soldered to a conductor pattern that protrudes to the side and is wired along the back surface.
　軸部６ａの中間付近の位置には、導電性のバネ受けリング１５が固定され、貫通孔１２内で下向き段部１４との間に圧縮して配置される外部側コイルスプリング１３の小径部１３ｂを下方から支持している。外部側コイルスプリング１３は、導電性のコイルを円錐台の外形に沿って巻回した円錐台状コイルスプリングであり、外部コンタクト４の一部の下向き段部１４とその下方の外部端子６に固定されたバネ受けリング１５の間に弾装されることにより、外部端子６がプリント配線基板３０に固定されていない実装前（図１参照）は、鍔部６ｂがフランジ部１１の平面に弾性接触するように作用して外部端子６を同軸コネクタ１０側に仮保持し、外部端子６がプリント配線基板３０に固定された実装後（図３、図４参照）は、フランジ部１１の平面を鍔部６ｂの底面に弾性接触するように作用して同軸コネクタ１０を鍔部６ｂの底面に沿って位置決めしている。 A conductive spring receiving ring 15 is fixed at a position near the middle of the shaft portion 6a, and the small diameter portion 13b of the outer side coil spring 13 disposed by being compressed between the through hole 12 and the downward step 14 Support from below. The outer side coil spring 13 is a frustoconical coil spring formed by winding a conductive coil along the outer shape of a truncated cone, and is fixed to the downward step 14 of a part of the outer contact 4 and the outer terminal 6 below it. Before mounting (see FIG. 1) in which the external terminal 6 is not fixed to the printed wiring board 30 by being resiliently mounted between the spring receiving rings 15 (see FIG. 1), the flange portion 6 b elastically contacts the plane of the flange portion 11 The external terminals 6 are temporarily held on the side of the coaxial connector 10 so that the external terminals 6 are fixed to the printed wiring board 30 (see FIGS. 3 and 4). The coaxial connector 10 is positioned along the bottom of the collar 6b by acting in resilient contact with the bottom of the portion 6b.
　また、外部端子６は、外部側コイルスプリング１３が円錐台状に形成され、その小径部１３ｂを外部端子６の軸部６ａ側で受けるので、外部端子６に一時的な外力が加わってもその外力が解かれれば、外部側コイルプリング１３の弾性によって軸部６ａは、大径部１３ａの中心である貫通孔１２の中心軸に沿った位置に復帰する。すなわち、外部端子６は、貫通孔１２内でプリント配線基板３０の平面に平行に相対移動自在に支持されているが、実装前の同軸コネクタ１０側に仮保持されている状態で、軸部６ａが貫通孔１２の中心軸に沿った一定位置に保持され、プリント配線基板３０の対応する導電パターンとの位置ずれがなく、正確に相互を半田接続できる。 Further, since the external side coil spring 13 is formed in a truncated cone shape and the small diameter portion 13b of the external terminal 6 is received on the side of the shaft portion 6a of the external terminal 6, even if a temporary external force is applied to the external terminal 6 When the external force is released, the shaft portion 6a returns to the position along the central axis of the through hole 12 which is the center of the large diameter portion 13a by the elasticity of the outer side coil spring 13. That is, although the external terminal 6 is supported relatively movably in parallel to the plane of the printed wiring board 30 in the through hole 12, the shaft 6a is temporarily held on the side of the coaxial connector 10 before mounting. Is held at a fixed position along the central axis of the through hole 12, and there is no misalignment with the corresponding conductive pattern of the printed wiring board 30, and accurate mutual solder connection is possible.
　また、外部端子６の軸部６ａが貫通孔１２内を相対移動する間、外部端子６と外部コンタクト４とは、その間に圧縮して配置される外部側コイルスプリング１３を介して常に電気接続しているので、同軸コネクタ１０をプリント配線基板３０に実装した後に同軸コネクタ１０が移動するいずれの位置にあっても、外部コンタクト４とプリント配線基板３０の対応する導電パターンは電気接続する。 In addition, while the shaft portion 6a of the external terminal 6 moves relative to the inside of the through hole 12, the external terminal 6 and the external contact 4 are always electrically connected via the external side coil spring 13 disposed in a compressed manner therebetween. Therefore, regardless of the position at which the coaxial connector 10 moves after the coaxial connector 10 is mounted on the printed wiring board 30, the corresponding conductive patterns of the external contacts 4 and the printed wiring board 30 are electrically connected.
　中心コンタクト２の有蓋円筒状の中心端子受部８内には、ロッド状に起立する中心端子５の上部が収容される。中心端子５は、導電性金属材料でロッド状に形成され、その上方の頭部５ａが中心端子受部８の内頂面に当接する状態で、下方の軸部５ｂが同軸コネクタ１０の下方に配設されるプリント配線基板３０を貫通してその背面側に突出する長さとなっている。これにより、中心端子５の下端は、同軸コネクタ１０をプリント配線基板３０上に配置した状態で、プリント配線基板３０の背面側に突出し、背面に沿って配線される導体パターンに半田接続される。 The upper portion of the center terminal 5 standing up like a rod is accommodated in the cylindrical center terminal receiving portion 8 of the center contact 2 with a lid. The center terminal 5 is formed in a rod shape of a conductive metal material, and the lower shaft 5 b is located below the coaxial connector 10 in a state where the upper head 5 a is in contact with the inner top surface of the center terminal receiving portion 8. It has a length which penetrates the printed wiring board 30 to be disposed and protrudes to the back side. Thereby, the lower end of the center terminal 5 protrudes to the back side of the printed wiring board 30 in a state where the coaxial connector 10 is disposed on the printed wiring board 30, and is soldered to the conductor pattern wired along the back side.
　中心端子５の頭部５ａの外径は、その下方の軸部５ｂよりやや長く、頭部５ａの下面で後述する中心側コイルスプリング１７の小径部１７ｂを受けるようになっている。また、図１に示すように、頭部５ａの外径に比べて中心端子受部８の内頂面の内径は十分に長いので、中心端子受部８の内部は、中心端子５をプリント配線基板３０と平行な水平方向に相対移動自在とする相対移動空隙８’となっている。 The outer diameter of the head portion 5a of the center terminal 5 is slightly longer than the lower shaft portion 5b, and the lower surface of the head portion 5a receives a small diameter portion 17b of the center side coil spring 17 described later. Further, as shown in FIG. 1, since the inner diameter of the inner top surface of the central terminal receiving portion 8 is sufficiently longer than the outer diameter of the head portion 5a, the central terminal 5 is printed by the inside of the central terminal receiving portion 8. It is a relative movement air gap 8 'that allows relative movement in the horizontal direction parallel to the substrate 30.
　中心端子受部８の中には、外部側コイルスプリング１３と同様に、コイルを円錐台の外形に沿って巻回して円錐台状とした中心側コイルスプリング１７が、コイルスプリング１３と上下逆向きに配置されている。中心側コイルスプリング１７は、頭部５ａの下面と、導電性金属板からなるワッシャ１８を中心端子受部８の内壁面の下端に沿って取り付けて形成される中心端子受部８の上向き段部１８ａとの間に、小径部１７ｂが頭部５ａに、大径部１７ａが上向き段部１８ａに弾性接触するように圧縮して配設される。 As in the case of the outer side coil spring 13, in the center terminal receiving portion 8, the center side coil spring 17 in which the coil is wound along the outer shape of the truncated cone to form a truncated cone is upside down with the coil spring 13. Is located in The center side coil spring 17 is formed by attaching the lower surface of the head 5 a and the washer 18 made of a conductive metal plate along the lower end of the inner wall surface of the center terminal receiving portion 8 and forming an upward step of the center terminal receiving portion 8 The small diameter portion 17b is compressed between the head 18a and the head portion 5a, and the large diameter portion 17a is in compression contact with the upward step 18a.
　中心側コイルスプリング１７が、中心端子５の頭部５ａの下面とその下方の中心端子受部８の上向き段部１８ａ間に弾装されることにより、中心端子５がプリント配線基板３０に固定されていない実装前（図１参照）は、頭部５ａが中心端子受部８の内頂面に弾性接触するように作用して中心端子５を同軸コネクタ１０側に仮保持し、中心端子５がプリント配線基板３０に固定された実装後（図３、図４参照）は、中心端子受部８をプリント配線基板３０の平面側に付勢するように作用して同軸コネクタ１０をプリント配線基板３０の平面に沿って位置決めしている。 The center terminal 5 is fixed to the printed wiring board 30 by resiliently mounting the center side coil spring 17 between the lower surface of the head 5a of the center terminal 5 and the upward step 18a of the center terminal receiving portion 8 below it. Before mounting (see FIG. 1), the head 5a acts in an elastic contact with the inner top surface of the center terminal receiving portion 8 to temporarily hold the center terminal 5 on the coaxial connector 10 side, and the center terminal 5 After mounting (see FIGS. 3 and 4) fixed to the printed wiring board 30, the coaxial connector 10 is acted to urge the center terminal receiving portion 8 to the flat side of the printed wiring board 30. It is positioned along the plane of.
　また、中心端子５は、中心側コイルプリング１７が円錐台状に形成され、その小径部１７ｂを中心端子５の頭部５ａ側で受けるので、中心端子５に一時的な外力が加わってもその外力が解かれれば、中心側コイルプリング１７の弾性によって頭部５ａは、大径部１７ａの中心である中心端子受部８の中心軸に沿った位置に復帰する。すなわち、中心端子５は、中心端子受部８内でプリント配線基板３０の平面に平行に相対移動自在に支持されているが、実装前の同軸コネクタ１０側に仮保持されている状態で、その頭部５ａが中心端子受部８の中心軸に沿った一定位置に保持され、プリント配線基板３０の対応する導電パターンとの位置ずれがなく、正確に相互を半田接続できる。 Further, since the center side coil spring 17 is formed in a truncated cone shape and the small diameter portion 17b of the center terminal 5 is received on the head 5a side of the center terminal 5, even if a temporary external force is applied to the center terminal 5 When the external force is released, the head 5a returns to a position along the central axis of the center terminal receiving portion 8 which is the center of the large diameter portion 17a by the elasticity of the center side coil spring 17. That is, although the center terminal 5 is supported relatively movably in parallel with the plane of the printed wiring board 30 in the center terminal receiving portion 8, it is temporarily held on the side of the coaxial connector 10 before mounting. The head portion 5a is held at a fixed position along the central axis of the center terminal receiving portion 8, there is no positional deviation from the corresponding conductive pattern of the printed wiring board 30, and accurate mutual solder connection can be made.
　また、中心端子８が中心端子受部８内を相対移動する間、中心端子５と中心コンタクト２とは、その間に圧縮して配置される中心側コイルスプリング１７を介して常に電気接続しているので、同軸コネクタ１０をプリント配線基板３０に実装した後に同軸コネクタ１０が移動するいずれの位置にあっても、中心コンタクト２とプリント配線基板３０の対応する導電パターンは電気接続する。 Further, while the center terminal 8 moves relative to the inside of the center terminal receiving portion 8, the center terminal 5 and the center contact 2 are always electrically connected via the center side coil spring 17 arranged to be compressed therebetween. Therefore, regardless of the position at which the coaxial connector 10 moves after the coaxial connector 10 is mounted on the printed wiring board 30, the corresponding conductive patterns of the central contact 2 and the printed wiring board 30 are electrically connected.
　同軸コネクタ１０は、図４に示すように、筐体３１に穿設された窓孔３１ａを貫通して取り付けられるが、筐体３１内を防水する構造とするために、筒状外部シェル９
周りに弾性防水リングであるＯリング１９が取り付けられ、また、筒状外部シェル９とインシュレータ３との隙間及びインシュレータ３と中心ピン７との隙間を埋めて密封するため、筒状外部シェル９内のインシュレータ３の上方が防水接着剤層２１で埋められている。 As shown in FIG. 4, the coaxial connector 10 is attached through the window hole 31 a drilled in the housing 31, but in order to make the inside of the housing 31 waterproof, the cylindrical outer shell 9 is formed.
An O-ring 19 which is an elastic waterproof ring is attached around the inside of the cylindrical outer shell 9 in order to fill and seal the gap between the cylindrical outer shell 9 and the insulator 3 and the gap between the insulator 3 and the center pin 7. The upper part of the insulator 3 is filled with the waterproof adhesive layer 21.
　このように構成された同軸コネクタ１０は、図２に示すように、中心端子受部８の平面がインシュレータ３の底面に当接するまで、インシュレータ３の下方から中心コンタクト２の中心ピン７を圧入し、中心コンタクト２が組み付けられたインシュレータ３を外部コンタクト４の筒状外部シェル９の下方から圧入して組み付ける。続いて、上方からＯリング１９を筒状外部シェル９の外側に取り付けると共に、筒状外部シェル９内のインシュレータ３の平面が露出する下方に防水接着剤を注入し、硬化させて防水接着剤層２１を形成して、中心コンタクト２の軸周りにインシュレータ３で絶縁された外部コンタクト４が組み付けられた同軸コネクタ１０が製造される。 As shown in FIG. 2, the coaxial connector 10 configured in this manner presses the center pin 7 of the center contact 2 from below the insulator 3 until the plane of the center terminal receiving portion 8 abuts on the bottom surface of the insulator 3. The insulator 3 assembled with the central contact 2 is press-fit from below the cylindrical outer shell 9 of the outer contact 4 and assembled. Subsequently, the O-ring 19 is attached to the outside of the cylindrical outer shell 9 from above, and a waterproof adhesive is injected below the surface where the insulator 3 in the cylindrical outer shell 9 is exposed and cured to form a waterproof adhesive layer. A coaxial connector 10 is manufactured in which the external contacts 4 insulated by the insulator 3 are assembled around the axis of the central contact 2 by forming 21.
　この同軸コネクタ１０には、プリント配線基板３０への実装前に、中心端子５と２本の外部端子６が仮保持される。中心端子５は、頭部５ａの下面とワッシャ１８の間に中心端子５の軸部５ｂを挿通させた中心側コイルスプリング１７とともに中心端子受部８の下方から挿入し、ワッシャ１８を圧入、内嵌などの方法で中心端子受部８の内壁面の下端に沿って取り付ける。これにより、前述したように中心側コイルスプリング１７は、中心端子５の頭部５ａの下面と中心端子受部８の上向き段部１８ａ間に弾装され、中心端子５は頭部５ａが中心端子受部８の内頂面に弾性接触した状態で同軸コネクタ１０側に仮保持される。 The center terminal 5 and the two external terminals 6 are temporarily held in the coaxial connector 10 before mounting on the printed wiring board 30. The center terminal 5 is inserted from below the center terminal receiving portion 8 together with the center side coil spring 17 in which the shaft portion 5b of the center terminal 5 is inserted between the lower surface of the head 5a and the washer 18, and the washer 18 is press fit. Attach along the lower end of the inner wall surface of the center terminal holder 8 by a method such as fitting. Thereby, as described above, the center side coil spring 17 is resiliently mounted between the lower surface of the head portion 5a of the center terminal 5 and the upward step 18a of the center terminal receiving portion 8, and the center terminal 5 has the head portion 5a as the center terminal It is temporarily held on the side of the coaxial connector 10 in a state of being in elastic contact with the inner top surface of the receiving portion 8.
　また、一対の外部端子６は、それぞれ貫通孔１２に上方から軸部６ａを貫通させ、鍔部６ｂがフランジ部１１の平面に当接した状態で、円錐台形の上下を逆転させた外部側コイルスプリング１３を下方から外部端子６の軸部６ａを挿通させながら貫通孔１２内に収容する。外部コイルスプリング１３の大径部１３ａが下向き段部１４に当接した後、小径部１３ｂを上方に更に押し込み、小径部１３ｂがフランジ部１１の底面より上方で、外部コイルスプリング１３が十分に圧縮される位置で、小径部１３ｂの下方に配置したバネ受けリング１５を軸部６ａの軸周りに、溶着、外嵌等の方法で取り付ける。これにより、前述したように外部側コイルスプリング１３は、フランジ部１１の下向き段部１４と外部端子６の軸部６ａに取り付けられたバネ受けリング１６の間に弾装され、外部端子６は鍔部６ｂがフランジ部１１の平面に弾性接触した状態で同軸コネクタ１０側に仮保持される。 Further, the pair of external terminals 6 has the shaft 6a penetrating the through hole 12 from the upper side, and the external coil in which the top and bottom of the truncated cone are reversed in a state where the flange 6b abuts on the plane of the flange 11. The spring 13 is accommodated in the through hole 12 while inserting the shaft portion 6 a of the external terminal 6 from below. After the large diameter portion 13a of the external coil spring 13 abuts on the downward stepped portion 14, the small diameter portion 13b is further pushed upward, and the small diameter portion 13b is sufficiently compressed above the bottom surface of the flange portion 11 In the position to be fixed, the spring receiving ring 15 disposed below the small diameter portion 13b is attached around the axis of the shaft portion 6a by welding, fitting, or the like. Thus, as described above, the outer coil spring 13 is resiliently mounted between the downward step 14 of the flange 11 and the spring receiving ring 16 attached to the shaft 6a of the outer terminal 6, and the outer terminal 6 is The portion 6 b is temporarily held on the side of the coaxial connector 10 in a state of being in elastic contact with the flat surface of the flange portion 11.
　同軸コネクタ１０に仮保持される中心端子５と外部端子６は、円錐台形の中心側コイルスプリング１７と外部側コイルスプリング１３の小径部１７ａ、１３ｂ側に取り付けられることにより大径部１７ａ、１３ａの中心である一定位置に位置決めされので、水平方向に相対移動自在に仮保持されるにもかかわらず、中心端子５の軸部５ｂや外部端子６の軸部６ａは、同軸コネクタ１０の一定位置で下方に突出し、対応するプリント配線基板３０の導電パターン（ここでは、対応する導電パターン連通するプリント配線基板３０のスルーホール）との位置ずれがなく、正確に半田接続を行うことができる。 The center terminal 5 and the external terminal 6 temporarily held by the coaxial connector 10 are attached to the small diameter portions 17a and 13b of the center side coil spring 17 and the outer side coil spring 13 of the truncated cone, and the large diameter portions 17a and 13a are provided. The shaft portion 5b of the center terminal 5 and the shaft portion 6a of the external terminal 6 are fixed at a predetermined position of the coaxial connector 10, although they are temporarily held so as to be relatively movable in the horizontal direction. There is no positional deviation from the corresponding conductive pattern of the printed wiring board 30 (in this case, the through hole of the printed wiring board 30 communicating with the corresponding conductive pattern) projecting downward, and solder connection can be performed accurately.
　同軸コネクタ１０を実装したプリント配線基板３０とプリント配線基板３０が取り付けられる筐体３１間に一定の取付誤差が生じている（図３では、筐体３１に対して図中右側にプリント配線基板３０の取付誤差が生じている）場合には、同軸コネクタ１０が筐体３１の窓孔３１ａに一致しない。このように取り付け誤差が生じている場合には、図４に示すように、同軸コネクタ１０を窓孔３１ａに貫通させながら、プリント配線基板３０を筐体３１に取り付け、プリント配線基板３０に対して同軸コネクタ１０を水平方向に移動させる（図４では、プリント配線基板３０に対して同軸コネクタ１０を左方に移動させる）ことにより、筐体３１とプリント配線基板３０との取り付け誤差を吸収する。このように、同軸コネクタ１０がプリント配線基板３０に対して一定の移動範囲で移動しても、中心コンタクト２は中心側コイルスプリング１７と中心端子５を介し、また、外部コンタクト４は、外部側コイルスプリング１３と外部端子６を介し、対応する導電パターンに電気接続する。 A fixed mounting error occurs between the printed wiring board 30 on which the coaxial connector 10 is mounted and the housing 31 to which the printed wiring board 30 is attached (in FIG. If the mounting error occurs, the coaxial connector 10 does not match the window hole 31 a of the housing 31. As described above, when the mounting error occurs, the printed wiring board 30 is attached to the housing 31 while the coaxial connector 10 is penetrated through the window hole 31a as shown in FIG. By moving the coaxial connector 10 in the horizontal direction (in FIG. 4, the coaxial connector 10 is moved to the left with respect to the printed wiring board 30), an attachment error between the housing 31 and the printed wiring board 30 is absorbed. As described above, even if the coaxial connector 10 moves within a fixed movement range with respect to the printed wiring board 30, the central contact 2 passes through the central coil spring 17 and the central terminal 5, and the external contact 4 is on the outer side. Electrical connection is made to the corresponding conductive pattern through the coil spring 13 and the external terminal 6.
　本発明によれば、筐体３１と同軸コネクタ１０を実装するプリント配線基板３０との間に取り付け誤差が生じていても、筐体３１の窓孔３１ａ内に同軸コネクタ１０を移動させる隙間を形成する必要がないので、筒状外部シェル９と窓孔３１ａの間にＯリング１９を密着して配置することができ、筐体３１内を簡単な構造で確実に防水構造とすることきができる。 According to the present invention, even if a mounting error occurs between the housing 31 and the printed wiring board 30 on which the coaxial connector 10 is mounted, a gap for moving the coaxial connector 10 is formed in the window hole 31a of the housing 31. Since it is not necessary to do so, the O-ring 19 can be closely disposed between the cylindrical outer shell 9 and the window hole 31a, and the inside of the housing 31 can be reliably waterproofed with a simple structure. .
　また、同軸コネクタ１０をプリント配線基板３０に対して可動させても、同軸コネクタ１０自体の形状は変化しないので、同軸コネクタ１０の特性インピーダンスが変化せず、中心コンタクト２を流れる高周波信号が減衰しない。 Further, even if the coaxial connector 10 is moved relative to the printed wiring board 30, the shape of the coaxial connector 10 itself does not change, so the characteristic impedance of the coaxial connector 10 does not change, and the high frequency signal flowing through the central contact 2 is not attenuated. .
　尚、上述の第１の実施の形態では、同軸コネクタ１０をプリント配線基板３０に実装した図３に示す状態で、同軸コネクタ１０は、フランジ部１１が外部端子６の鍔部６ｂとプリント配線基板３０の平面に挟まれ、上下方向での移動が規制される。しかしながら、同軸コネクタ１０の全体は、中心側コイルスプリング１７により下向きに付勢され、外部側コイルスプリング１３により逆方向の上向きに付勢されるので、前者の力が後者の合力に勝ればプリント配線基板３０の平面に当接し、逆に後者の合力が前者の力に勝れば鍔部６ｂの下面に当接し、上下方向では安定した位置で位置決めされない。 In the first embodiment described above, in the state shown in FIG. 3 in which the coaxial connector 10 is mounted on the printed wiring board 30, in the coaxial connector 10, the flange portion 11 is the flange portion 6b of the external terminal 6 and the printed wiring board It is pinched by 30 planes, and the movement in the vertical direction is restricted. However, since the entire coaxial connector 10 is biased downward by the center side coil spring 17 and biased upward in the opposite direction by the outer side coil spring 13, printing is performed if the former force exceeds the latter resultant force. If it comes in contact with the plane of the wiring board 30 and the resultant force of the latter overcomes the former force, it abuts against the lower surface of the collar 6b, and it is not positioned at a stable position in the vertical direction.
　そこで、図５に示すように、第２の実施の形態に係る同軸コネクタの実装構造２０では、２本の外部端子も第１の実施の形態に係る中心端子５と同様に同時コネクタ１０に仮保持する構造として、プリント配線基板３０に実装した状態で、同軸コネクタ１０に作用する全ての力をプリント配線基板３０への当接方向として同軸コネクタ１０の上下方向の位置を安定させる。以下、この第２の実施の形態に係る同軸コネクタの実装構造２０では、第１の実施の形態と同一若しくは同一に作用する構成は、同一番号を付してその説明を省略する。 Therefore, as shown in FIG. 5, in the coaxial connector mounting structure 20 according to the second embodiment, the two external terminals are also temporarily mounted on the simultaneous connector 10 in the same manner as the center terminal 5 according to the first embodiment. As a structure for holding, in a state of being mounted on the printed wiring board 30, the vertical position of the coaxial connector 10 is stabilized with all forces acting on the coaxial connector 10 as the contact direction to the printed wiring board 30. Hereinafter, in the mounting structure 20 of the coaxial connector according to the second embodiment, configurations that function the same as or the same as the first embodiment are given the same reference numerals, and the description thereof will be omitted.
　第２の実施の形態では、外部コンタクト４の両側に突出する一対のフランジ部１１に、それぞれ下方に開口する円筒状凹部２２が凹設され、円筒状凹部２２内に外部端子２６の上部が起立して収容される。外部端子２６は、導電性金属材料でロッド状に形成され、その上方の頭部２６ａが円筒状凹部２２の内頂面に当接する状態で、下端が同軸コネクタ１０の下方に配設されるプリント配線基板３０を貫通してその背面側に突出する長さとなっている。これにより、外部端子２６の下端は、同軸コネクタ１０をプリント配線基板３０上に配置した状態で、プリント配線基板３０の背面側に突出し、背面に沿って配線される対応する導体パターンに半田接続される。 In the second embodiment, cylindrical recesses 22 respectively opening downward are recessed in a pair of flanges 11 protruding on both sides of the external contact 4, and the upper portions of the external terminals 26 stand in the cylindrical recesses 22. To be accommodated. The outer terminal 26 is formed in a rod shape of a conductive metal material, and the lower end thereof is disposed below the coaxial connector 10 in a state where the upper head portion 26 a is in contact with the inner top surface of the cylindrical recess 22. It has a length which penetrates the wiring board 30 and protrudes to the back side. Thereby, the lower end of the external terminal 26 protrudes to the back side of the printed wiring board 30 with the coaxial connector 10 arranged on the printed wiring board 30, and is soldered to the corresponding conductor pattern wired along the back side. Ru.
　外部端子２６の頭部２６ａの外径は、その下方の軸部２６ｂよりやや長く、頭部２６ａの下面で外部側コイルスプリング２３の小径部２３ｂを受けるようになっている。また、図５に示すように、頭部２６ａの外径に比べて円筒状凹部２２の内頂面の内径は十分に長いので、円筒状凹部２２は、外部端子２６をプリント配線基板３０と平行な水平方向に相対移動自在とする相対移動空隙となっている。 The outer diameter of the head portion 26a of the external terminal 26 is slightly longer than the lower shaft portion 26b, and the lower surface of the head portion 26a receives the small diameter portion 23b of the outer side coil spring 23. Further, as shown in FIG. 5, since the inner diameter of the inner top surface of the cylindrical recess 22 is sufficiently longer than the outer diameter of the head portion 26 a, the cylindrical recess 22 has the external terminal 26 parallel to the printed wiring board 30. It is a relative movement gap that allows relative movement in the horizontal direction.
　円筒状凹部２２の中には、中心側コイルスプリング１７と同様に、コイルを円錐台の外形に沿って巻回して円錐台状とした外部側コイルスプリング２３が配置されている。外部側コイルスプリング２３は、頭部５ａの下面と、導電性金属板からなるワッシャ２４を円筒状凹部２２の内壁の下端に沿って取り付けて形成される円筒状凹部２２の上向き段部２４ａとの間に、小径部２３ｂが頭部２６ａに、大径部２３ａが上向き段部２４ａに弾性接触するように圧縮して配設される。 In the cylindrical recess 22, like the center side coil spring 17, an outer side coil spring 23 which is formed into a truncated cone shape by winding a coil along the outer shape of a truncated cone is disposed. The outer side coil spring 23 has a lower surface of the head portion 5a and an upward step 24a of the cylindrical recess 22 formed by attaching a washer 24 made of a conductive metal plate along the lower end of the inner wall of the cylindrical recess 22. In the meantime, the small diameter portion 23 b is compressed and disposed so as to elastically contact the head portion 26 a and the large diameter portion 23 a with the upward step portion 24 a.
　外部側コイルスプリング２３が、外部端子２６の頭部２６ａの下面とその下方の円筒状凹部２２の上向き段部２４ａ間に弾装されることにより、外部端子２６がプリント配線基板３０に固定されていない実装前（図５参照）は、頭部２６ａが円筒状凹部２２の内頂面に弾性接触するように作用して外部端子２６を同軸コネクタ１０側に仮保持し、外部端子２６がプリント配線基板３０に固定された実装後は、フランジ部１１をプリント配線基板３０の平面側に付勢するように作用して同軸コネクタ１０をプリント配線基板３０の平面に当接させて位置決めしている。 The external terminal 26 is fixed to the printed wiring board 30 by resiliently mounting the outer side coil spring 23 between the lower surface of the head portion 26 a of the external terminal 26 and the upward step 24 a of the cylindrical recess 22 therebelow. Before mounting (see FIG. 5), the head portion 26a acts to elastically contact the inner top surface of the cylindrical recess 22 to temporarily hold the external terminal 26 on the coaxial connector 10 side, and the external terminal 26 is printed wiring After mounting on the substrate 30, the coaxial connector 10 is positioned in contact with the plane of the printed wiring board 30 by acting to urge the flange portion 11 to the plane side of the printed wiring board 30.
　以上の各実施の形態では、中心端子５と外部端子６、２６をプリント配線基板３０の背面まで貫通させてその背面の対応する導電パターンに半田接続しているが、プリント配線基板３０の表面で対向する導電パターンに半田接続する表面実装構造にも適用できる。 In each of the above embodiments, the center terminal 5 and the external terminals 6 and 26 are penetrated to the back surface of the printed wiring board 30 and soldered to the corresponding conductive pattern on the back surface. It is applicable also to the surface mounting structure soldered to the conductive pattern which counters.
　また、上述の各実施の形態では、外部端子６の軸部６ａ、中心端子受部８の内壁、円筒状凹部２２の内壁に、それぞれ導電性の別部品であるバネ受けリング１６、ワッシャ１８、２４を取り付けて、外部端子６の軸部６ａ、中心端子受部８、円筒状凹部２２自体に凹凸を設けて外部側コイルスプリング１３、２３、中心側コイルスプリング１７の一方を受けるバネ受けとしてもよい。 In each of the above-described embodiments, the spring receiving ring 16 and the washer 18, which are separate conductive parts, are provided on the shaft 6a of the external terminal 6, the inner wall of the center terminal receiving portion 8 and the inner wall of the cylindrical recess 22 respectively. 24 is mounted, and the shaft 6a of the external terminal 6, the center terminal receiving portion 8, and the cylindrical recess 22 are provided with irregularities to serve as a spring receiver for receiving one of the outer side coil springs 13 and 23 and the center side coil spring 17. Good.
　また、外部側コイルスプリング１３、２３及び中心側コイルスプリング１７を円錐台状に形成しているが、同軸コネクタ１０が外部端子６、２６及び中心端子５に対して相対移動する各位置で外部コンタクト４と外部端子６、２６及び中心コンタクト２と中心端子５とを常時電気接続するものであれば、その形状は円錐台状に限られない。 Further, although the outer side coil springs 13 and 23 and the center side coil spring 17 are formed in a truncated cone shape, the external contacts at respective positions where the coaxial connector 10 moves relative to the external terminals 6 and 26 and the center terminal 5 The shape is not limited to the truncated cone shape as long as it electrically connects 4 and external terminals 6 and 26 and center contact 2 and center terminal 5 at all times.
