上記のようなカードエッジコネクタに振動が作用すると、ハーネス側ハウジングと基板側ハウジングが嵌合方向に相対変位して、端子金具と接点部との間で微摺動摩耗が生じる。そのため、振動を長期間に亘って断続的に受けると、端子金具と接点部との間で接触不良を来すことが懸念される。
本発明は上記のような事情に基づいて完成されたものであって、回路基板とハーネス側の端子金具との接触信頼性の向上を図ることを目的とする。 When vibration acts on the card edge connector as described above, the harness-side housing and the board-side housing are relatively displaced in the fitting direction, and fine sliding wear occurs between the terminal fitting and the contact portion. Therefore, when vibration is intermittently received over a long period of time, there is a concern that a contact failure may occur between the terminal fitting and the contact portion.
The present invention has been completed based on the above situation, and an object thereof is to improve the contact reliability between a circuit board and a harness side terminal fitting.

本発明は、
ハーネス側ハウジングに複数の端子金具を並列配置したハーネス側コネクタと、基板側ハウジングの正面から回路基板の接続端縁部を突出させた基板側コネクタとを備え、前記基板側ハウジングを前記ハーネス側ハウジングに対しその前方から嵌合すると、前記複数の端子金具が前記接続端縁部に弾性接触するカードエッジコネクタであって、
前記ハーネス側コネクタと前記基板側コネクタのうち少なくともいずれか一方の前記コネクタに設けられ、他方の前記コネクタに当接することにより、前記端子金具と前記回路基板が前記回路基板の板面と平行に相対変位するのを規制可能な変位規制手段と、
前記ハーネス側ハウジングに形成され、前記回路基板の前記接続端縁部を挿入させる基板収容空間と、
前記ハーネス側ハウジングに設けられ、前記基板収容空間内に挿入された前記接続端縁部に対し弾性的に当接することで前記変位規制手段としての機能を発揮する弾性当接部材と、
前記ハーネス側ハウジング内に形成され、前記端子金具を挿入可能であって前記基板収容空間に連通する複数の端子収容室とを備え、
前記複数の端子収容室のうち前記端子金具が挿入されていない前記端子収容室に、前記弾性当接部材が収容されているところに特徴を有する。 The present invention
A harness-side connector having a plurality of terminal fittings arranged in parallel on the harness-side housing, and a board-side connector having a connection edge of a circuit board projecting from the front of the board-side housing, the board-side housing being the harness-side housing When it is fitted from the front, the plurality of terminal fittings are card edge connectors that elastically contact the connection end edges,
Provided in at least one of the harness-side connector and the board-side connector and contacting the other connector, the terminal fitting and the circuit board are relatively parallel to the plate surface of the circuit board. A displacement regulating means capable of regulating displacement ;
A board housing space formed in the harness side housing and into which the connection edge of the circuit board is inserted;
An elastic contact member that is provided in the harness-side housing and exerts a function as the displacement restricting means by elastically contacting the connection end edge portion inserted into the board housing space;
A plurality of terminal accommodating chambers formed in the harness side housing, into which the terminal fittings can be inserted and communicated with the substrate accommodating space;
The elastic contact member is accommodated in the terminal accommodation chamber in which the terminal fitting is not inserted among the plurality of terminal accommodation chambers .

ハーネス側ハウジングと基板側ハウジングが嵌合した状態では、変位規制手段により、回路基板と端子金具は回路基板の板面と平行に相対変位することを規制される。これにより、端子金具と回路基板との間の微摺動摩耗が防止されるので、端子金具と回路基板との接触信頼性に優れている。
また、基板収容空間内に挿入された回路基板の接続端縁部に対し、弾性当接部材が弾性的に当接すると、摩擦抵抗により、ハーネス側ハウジングに対する回路基板の相対変位が規制されるので、ハーネス側ハウジングに設けられている端子金具と回路基板との間の相対変位も規制される。
また、端子金具を挿入するための端子収容室を、弾性当接部材を収容するための収容空間として兼用しているので、既存のハーネス側ハウジングによって端子金具と回路基板の相対変位を規制できる。 In a state where the harness side housing and the board side housing are fitted, the displacement restriction means restricts the circuit board and the terminal fitting from being relatively displaced parallel to the plate surface of the circuit board. Thereby, the fine sliding wear between the terminal fitting and the circuit board is prevented, so that the contact reliability between the terminal fitting and the circuit board is excellent.
Further, when the elastic contact member elastically contacts the connection edge portion of the circuit board inserted into the board housing space, the relative displacement of the circuit board with respect to the harness side housing is restricted by the frictional resistance. The relative displacement between the terminal fitting provided in the harness side housing and the circuit board is also restricted.
Moreover, since the terminal accommodating chamber for inserting the terminal fitting is also used as the accommodating space for accommodating the elastic contact member, the relative displacement between the terminal fitting and the circuit board can be regulated by the existing harness side housing.

The elastic contact member 51 accommodated in the front cavity 27 causes the substrate portion 52 to come into contact with the upper surface of the terminal accommodating chamber 28 from below, and the support portion 54 against the lower surface of the terminal accommodating chamber 28 from above. The long portion 56 is brought into contact with the rear end edge of the receiving plate portion 32 obliquely from above, thereby taking a stable posture so as not to cause backlash. Further, the elastic contact member 51 is configured such that the upper end portion of the locking portion 53 comes into contact with the lance 17 from the front, and the long portion 56 comes into contact with the rear end edge of the receiving plate portion 32 from obliquely rearward. It is positioned in the front-rear direction.

基板収容空間２９に回路基板４１が挿入される前の状態では、端子収容室２８に収容された弾性当接部材５１が、その押圧部５９を前部キャビティ２７から基板収容空間２９内に突出させた状態で待機している。また、弾性当接部材５１は、撓み部５８とアーム部５５を弾性的に撓ませながら、押圧部５９を上方又は下方へ変位させるように弾性変形し得るようになっている。弾性当接部が弾性変形していない状態において、上段の押圧部５９と下段の押圧部５９との間の最小上下間隔は、回路基板４１の板厚寸法よりも小さい寸法に設定されている。 In a state before the circuit board 41 is inserted into the board housing space 29, the elastic contact member 51 housed in the terminal housing chamber 28 causes the pressing portion 59 to protrude from the front cavity 27 into the board housing space 29. Waiting in the state. The elastic contact member 51 can be elastically deformed so as to displace the pressing portion 59 upward or downward while elastically bending the bending portion 58 and the arm portion 55. In a state where the elastic contact portion is not elastically deformed, the minimum vertical distance between the upper pressing portion 59 and the lower pressing portion 59 is set to be smaller than the plate thickness of the circuit board 41.

図１，２に示すように、本実施例１には、変位規制手段５０を構成するハーネス側ガイド部３９と、基板側ガイド部４３が設けられている。ハーネス側ガイド部３９は、フード部１３の内周面を、前後方向（ハーネス側コネクタＨａと基板用コネクタの嵌合方向と平行な方向）に細長く延びるように切欠した溝状をなす。ハーネス側ガイド部３９は、フード部１３の上壁部に左右一対形成され、下壁部にも左右一対形成され、左右両側壁部には、夫々、１本ずつ形成されている。基板側ガイド部４３は、基板側ハウジング４０ａの外周面から、前後方向に細長く延びてリブ状に突出した形態である。基板側ガイド部４３は、基板側ハウジング４０ａの上面に左右一対形成され、下面にも左右一対形成され、左右両外側面には、夫々、１本ずつ形成されている。ハーネス側ガイド部３９と基板側ガイド部４３は、両コネクタＨａ，Ｐａを嵌合する過程で、ガタ付きなく摺接しながら嵌合するようになっている。 As shown in FIGS. 1 and 2, the first embodiment is provided with a harness side guide portion 39 and a substrate side guide portion 43 that constitute the displacement regulating means 50. The harness side guide portion 39 has a groove shape in which the inner peripheral surface of the hood portion 13 is cut out so as to be elongated in the front-rear direction (a direction parallel to the fitting direction of the harness side connector Ha and the board connector). A pair of left and right harness side guide portions 39 is formed on the upper wall portion of the hood portion 13, a pair of left and right portions are also formed on the lower wall portion, and one pair is formed on each of the left and right side wall portions. The board | substrate side guide part 43 is the form which extended in the front-back direction from the outer peripheral surface of the board | substrate side housing 40a, and protruded in rib shape. A pair of left and right substrate-side guide portions 43 are formed on the upper surface of the substrate-side housing 40a, a pair of left and right surfaces are also formed on the lower surface, and one is formed on each of the left and right outer surfaces. The harness-side guide portion 39 and the board-side guide portion 43 are fitted in a process of fitting both the connectors Ha and Pa while sliding in contact with each other.

＜実施例１の作用及び効果＞
両コネクタＨａ，Ｐａを嵌合する過程では、回路基板４１が基板挿入口３１を通過して基板収容空間２９に挿入される。基板収容空間２９に挿入された回路基板４１は、弾性当接部材５１の押圧部５９と干渉し、押圧部５９を上方又は下方へ変位させながら弾性当接部材５１を弾性変形させる。すると、弾性当接部材５１の弾性復元力により、回路基板４１が上段の弾性当接部材５１と下段の弾性当接部材５１との間で上下から弾性的に挟み付けられる。この弾性的な挟圧作用に起因する摩擦により、回路基板４１は、弾性当接部材５１に対して回路基板４１の板面と平行な方向（前後方向及び左右方向）への相対変位を規制される。これにより、回路基板４１と端子金具３４との間においても、回路基板４１の板面と平行な方向における微摺動摩耗が防止される。 <Operation and Effect of Example 1>
In the process of fitting both the connectors Ha and Pa, the circuit board 41 passes through the board insertion port 31 and is inserted into the board housing space 29. The circuit board 41 inserted into the board housing space 29 interferes with the pressing portion 59 of the elastic contact member 51 and elastically deforms the elastic contact member 51 while displacing the pressing portion 59 upward or downward. Then, due to the elastic restoring force of the elastic contact member 51, the circuit board 41 is elastically sandwiched between the upper elastic contact member 51 and the lower elastic contact member 51 from above and below. Due to the friction caused by this elastic pinching action, the circuit board 41 is restricted from relative displacement in the direction parallel to the plate surface of the circuit board 41 (front-rear direction and left-right direction) with respect to the elastic contact member 51. The Thereby, even between the circuit board 41 and the terminal metal fitting 34, the fine sliding wear in the direction parallel to the plate surface of the circuit board 41 is prevented.

また、両コネクタＨａ，Ｐａを嵌合する過程では、複数のハーネス側ガイド部３９と複数の基板側ガイド部４３がガタ付きなく摺接しながら嵌合することにより、両コネクタＨａ，Ｐａの位置関係が安定するので、両コネクタＨａ，Ｐａの嵌合が円滑に進む。両コネクタＨａ，Ｐａが嵌合した状態では、ハーネス側ガイド部３９と基板側ガイド部４３との間に摩擦により、両ハウジング１０ａ，４０ａは、回路基板４１の板面と平行な方向（前後方向及び左右方向）への相対変位が規制される。これにより、端子金具３４と回路基板４１との間の微摺動摩耗が防止され、接触状態が安定する。また、ハーネス側ガイド部３９と基板側ガイド部４３との間に摩擦により、両ハウジング１０ａ，４０ａは上下方向への相対変位も規制される。これにより、端子金具３４と回路基板４１との間の接触圧が変動することが防止される。 Further, in the process of fitting both the connectors Ha and Pa, the plurality of harness side guide portions 39 and the plurality of board side guide portions 43 are fitted in sliding contact with no backlash, whereby the positional relationship between the connectors Ha and Pa. Is stable, the fitting of both the connectors Ha and Pa proceeds smoothly. In a state where both connectors Ha and Pa are fitted, both housings 10a and 40a are parallel to the plate surface of the circuit board 41 (front-rear direction) due to friction between the harness side guide portion 39 and the board side guide portion 43. And the relative displacement in the left-right direction) is restricted. Thereby, the fine sliding wear between the terminal metal fitting 34 and the circuit board 41 is prevented, and a contact state is stabilized. Further, the relative displacement in the vertical direction of both the housings 10a and 40a is also restricted by friction between the harness side guide part 39 and the board side guide part 43. This prevents the contact pressure between the terminal fitting 34 and the circuit board 41 from fluctuating.

また、本実施例１では、端子金具３４を挿入するための端子収容室２８を、弾性当接部材５１を収容するためのスペースとして兼用しているので、既存のハーネス側ハウジング１０ａによって端子金具３４と回路基板４１の相対変位を規制できる。また、ハーネス側ハウジング１０ａと基板側ハウジング４０ａを嵌合する際のガイド手段であるハーネス側ガイド部３９と基板側ガイド部４３が、変位規制手段としての機能を兼ね備えているので、これらのガイド部とは別に専用の変位規制手段を形成する場合に比べると、ハーネス側ハウジング１０ａと基板側ハウジング４０ａの形状が簡素化されている。 In the first embodiment, since the terminal accommodating chamber 28 for inserting the terminal fitting 34 is also used as a space for accommodating the elastic contact member 51, the terminal harness 34 is used by the existing harness side housing 10a. And the relative displacement of the circuit board 41 can be regulated. Moreover, since the harness side guide part 39 and the board side guide part 43 which are guide means at the time of fitting the harness side housing 10a and the board | substrate side housing 40a have the function as a displacement control means, these guide parts The shape of the harness side housing 10a and the board side housing 40a is simplified as compared with the case where a dedicated displacement regulating means is formed separately.

次に、本発明を具体化した参考例１を図８〜図１０を参照して説明する。本参考例１のカードエッジコネクタＢは、変位規制手段６０を上記実施例１とは異なる構成としたものである。カードエッジコネクタＢの基本構成については上記実施例１のカードエッジコネクタＡと同じであるため、同じ構成に関しては、同一符号を付し、構造、作用及び効果の説明は省略する。 < Reference Example 1 >
Next, Reference Example 1 embodying the present invention will be described with reference to FIGS. In the card edge connector B of the first reference example , the displacement regulating means 60 is configured differently from the first embodiment. Since the basic configuration of the card edge connector B is the same as that of the card edge connector A of the first embodiment, the same reference numerals are given to the same configuration, and the description of the structure, operation, and effect is omitted.

本参考例１の変位規制手段６０は、実施例１の弾性当接部材５１に変えて、ハーネス側コネクタＨｂのハーネス側ハウジング１０ｂに設けた四対の押圧突部６１によって構成されている。四対の押圧突部６１は、図８，９に示すように、基板挿入口３１の内面を構成する上下両受け板部３２から突出した形態であり、基板挿入口の左右方向に延びる長辺側開口縁３３に沿うように配置されている。上側の４つの押圧突部６１は、左右方向両端部を含む４位置にほぼ均等ピッチで配置されている。下側の４つの押圧突部６１も、左右方向両端部を含む４位置にほぼ均等ピッチで配置されている。 The displacement restricting means 60 of the first reference example is configured by four pairs of pressing protrusions 61 provided on the harness-side housing 10b of the harness-side connector Hb instead of the elastic contact member 51 of the first embodiment. As shown in FIGS. 8 and 9, the four pairs of pressing protrusions 61 protrude from the upper and lower receiving plate portions 32 constituting the inner surface of the board insertion port 31 and extend in the left-right direction of the board insertion port. It arrange | positions so that the side opening edge 33 may be followed. The upper four pressing protrusions 61 are arranged at substantially equal pitches at four positions including both ends in the left-right direction. The lower four pressing protrusions 61 are also arranged at substantially equal pitches at four positions including both ends in the left-right direction.

このように、上側の押圧突部６１と下側の押圧突部６１は、左右に間隔を空けた４位置において、上下に対向して対をなすように配置されている。また、上側の押圧突部６１の下面と下側の押圧突部６１の上面は、回路基板４１と平行な平面からなる。そして、上側の押圧突部６１の下面と下側の押圧突部６１の上面との上下間隔は、回路基板４１の板厚寸法と同じか、それよりも僅かに小さい寸法に設定されている。 As described above, the upper pressing protrusion 61 and the lower pressing protrusion 61 are arranged so as to be opposed to each other in the vertical direction at four positions spaced apart from each other on the left and right. Further, the lower surface of the upper pressing protrusion 61 and the upper surface of the lower pressing protrusion 61 are formed of a plane parallel to the circuit board 41. The vertical distance between the lower surface of the upper pressing protrusion 61 and the upper surface of the lower pressing protrusion 61 is set to be the same as or slightly smaller than the thickness of the circuit board 41.

基板収容空間２９に回路基板４１を挿入した状態では、上側の押圧突部６１が回路基板４１の上面に対して面当たり状態で当接するとともに、下側の押圧突部６１が回路基板４１の下面に対して面当たり状態で当接する。これにより、回路基板４１は、左右方向に間隔を空けた４カ所において、上下で対をなす四対の押圧突部６１によって上下から挟み付けられた状態となる。これにより、端子保持部材と回路基板４１は、回路基板４１の板面と平行な方向における相対変位が規制されるので、端子金具３４と回路基板４１も、回路基板４１の板面と平行な方向における微摺動摩耗が防止される。 In a state where the circuit board 41 is inserted into the board housing space 29, the upper pressing protrusion 61 is in contact with the upper surface of the circuit board 41 in a surface-contact state, and the lower pressing protrusion 61 is the lower surface of the circuit board 41. In contact with the surface. As a result, the circuit board 41 is sandwiched from above and below by the four pairs of pressing protrusions 61 that form a pair at the top and bottom at four positions spaced in the left-right direction. Thereby, since the relative displacement of the terminal holding member and the circuit board 41 in the direction parallel to the plate surface of the circuit board 41 is restricted, the terminal fitting 34 and the circuit board 41 are also parallel to the plate surface of the circuit board 41. Fine sliding wear is prevented.

＜参考例２＞
次に、本発明を具体化した参考例２を図１１〜図１６を参照して説明する。本参考例２のカードエッジコネクタＣは、変位規制手段７０を上記実施例１とは異なる構成としたものである。カードエッジコネクタＣの基本構成については上記実施例１のカードエッジコネクタＡと同じであるため、同じ構成に関しては、同一符号を付し、構造、作用及び効果の説明は省略する。 < Reference Example 2 >
Next, Reference Example 2 embodying the present invention will be described with reference to FIGS. The card edge connector C of the second reference example has a configuration in which the displacement restricting means 70 is different from that of the first embodiment. Since the basic configuration of the card edge connector C is the same as that of the card edge connector A of the first embodiment, the same reference numerals are given to the same configuration, and description of the structure, operation, and effect is omitted.

本参考例２の変位規制手段７０は、実施例１の弾性当接部材５１に変えて、ハーネス側コネクタＨｃのハーネス側ハウジング１０ｃに設けたハーネス側嵌合部７１（図１１〜１３参照）と、基板側コネクタＰｃの基板側ハウジング４０ｃに設けた基板側嵌合部７３（図１４，１５参照）とによって構成されている。ハーネス側嵌合部７１は、端子保持部材２２の前壁部３０（ハーネス側ハウジング１０ｃにおける基板側ハウジング４０ｃとの対向面）から前方へ突出した形態である。ハーネス側嵌合部７１は、左右方向に細長くリブ状に突出した形態であり、基板挿入口３１の上方と下方に、夫々、左右３本ずつ一列に並ぶように直列配置されている。左右に隣り合うハーネス側嵌合部７１の間には、切欠部７２が形成されている。 The displacement restricting means 70 of the second reference example is replaced with the elastic contact member 51 of the first embodiment, and a harness side fitting portion 71 (see FIGS. 11 to 13) provided in the harness side housing 10c of the harness side connector Hc. The board-side fitting portion 73 (see FIGS. 14 and 15) provided in the board-side housing 40c of the board-side connector Pc. The harness side fitting part 71 is a form protruding forward from the front wall part 30 of the terminal holding member 22 (a surface facing the board side housing 40c in the harness side housing 10c). The harness side fitting portion 71 is elongated in the left-right direction and protrudes in a rib shape, and is arranged in series above and below the board insertion port 31 so that three on each side are arranged in a row. A notch portion 72 is formed between the harness side fitting portions 71 adjacent to the left and right.

図１５に示すように、基板側嵌合部７３は、基板側ハウジング４０ｃの正面（基板側ハウジング４０ｃにおけるハーネス側ハウジング１０ｃとの対向面）から突出した形態である。基板側嵌合部７３は、回路基板４１を全周に亘って連続して包囲するように、横長の長円形をなし、左右方向に直線上に延びる上下一対の直線状嵌合部７４を有している。また、基板側ハウジング４０ｃの正面には、上側の直線状嵌合部７４の下面に対して直角に連なった形態の左右一対の補助嵌合部７５と、下側の直線状嵌合部７４の上面に対して直角に連なった形態の左右一対の補助嵌合部７５とが形成されている。 As shown in FIG. 15, the board-side fitting portion 73 has a form protruding from the front surface of the board-side housing 40 c (the surface facing the harness-side housing 10 c in the board-side housing 40 c). The board-side fitting part 73 has a horizontally long oval shape so as to continuously surround the circuit board 41 over the entire circumference, and has a pair of upper and lower linear fitting parts 74 extending linearly in the left-right direction. doing. Further, on the front surface of the substrate side housing 40c, there are a pair of left and right auxiliary fitting portions 75 connected in a right angle to the lower surface of the upper linear fitting portion 74, and a lower linear fitting portion 74. A pair of left and right auxiliary fitting portions 75 are formed in a form that is connected at right angles to the upper surface.

両コネクタＨｃ，Ｐｃを嵌合すると、上側の３つのハーネス側嵌合部７１が、基板側嵌合部７３の上側の直線状嵌合部７４の下面に対して面当たり状態で当接するとともに、下側の３つのハーネス側嵌合部７１が、基板側嵌合部７３の下側の直線状嵌合部７４の上面に対して面当たり状態で当接する。このハーネス側嵌合部７１と基板側嵌合部７３の嵌合により、ハーネス側ハウジング１０ｃと基板側ハウジング４０ｃが、回路基板４１の板面と平行に相対変位することが規制される。これにより、端子金具３４と回路基板４１が、回路基板４１の板面と平行な方向（前後方向及び左右方向）へ相対変位することに起因して微摺動摩耗することが防止される。 When both the connectors Hc and Pc are fitted, the upper three harness side fitting parts 71 come into contact with the lower surface of the upper linear fitting part 74 of the board side fitting part 73 in a surface contact state, The lower three harness-side fitting portions 71 are in contact with the upper surface of the lower linear fitting portion 74 of the board-side fitting portion 73 in a surface contact state. By the fitting of the harness side fitting portion 71 and the board side fitting portion 73, the relative displacement of the harness side housing 10 c and the board side housing 40 c in parallel with the plate surface of the circuit board 41 is restricted. As a result, the terminal fitting 34 and the circuit board 41 are prevented from being subjected to fine sliding wear due to relative displacement in the direction parallel to the plate surface of the circuit board 41 (front-rear direction and left-right direction).

また、ハーネス側ハウジング１０ｃの切欠部７２と、基板側ハウジング４０ｃの補助嵌合部７５が嵌合することにより、ハーネス側ハウジング１０ｃと基板側ハウジング４０ｃの左右方向への相対変位も規制される。さらに、切欠部７２と補助嵌合部７５との間の摩擦により、ハーネス側ハウジング１０ｃと基板側ハウジング４０ｃが上下方向へ相対変位することも規制される。 Further, by fitting the cutout portion 72 of the harness side housing 10c and the auxiliary fitting portion 75 of the board side housing 40c, the relative displacement in the left-right direction of the harness side housing 10c and the board side housing 40c is also restricted. Furthermore, the relative displacement of the harness-side housing 10c and the board-side housing 40c in the vertical direction is also restricted by the friction between the notch portion 72 and the auxiliary fitting portion 75.

The board-side coupling portion 83 has a shape protruding in a substantially horizontal plate shape from the left and right outer surfaces of the board-side housing 40d. Bolt holes 84 penetrating in the vertical direction are also formed in the board-side coupling portion 83.

両コネクタＨｄ，Ｐｄを嵌合した状態では、ハーネス側結合部８１の上面に基板側結合部８３が重なり、ボルト孔８２，８４同士が対応する。両コネクタＨｄ，Ｐｄを嵌合した後、２つのボルト孔８２，８４に対し上からボルト８５を差し込み、ハーネス側結合部８２の下方において、ボルト８５の下端部にナット８６をねじ込む。そして、ボルト８５とナット８６を締め付けると、ハーネス側結合部８１と基板側結合部８３が強固に結合され、ハーネス側ハウジング１０ｄと基板側ハウジング４０ｄが相対変位を規制された状態に固定される。これにより、端子金具３４と回路基板４１は、回路基板４１の板面と平行な方向への相対変位に起因して微摺動摩耗することを防止される。 In a state where both the connectors Hd and Pd are fitted, the board side coupling portion 83 overlaps the upper surface of the harness side coupling portion 81, and the bolt holes 82 and 84 correspond to each other. After fitting both the connectors Hd and Pd, the bolt 85 is inserted into the two bolt holes 82 and 84 from above, and a nut 86 is screwed into the lower end of the bolt 85 below the harness side coupling portion 82. When the bolt 85 and the nut 86 are tightened, the harness side coupling portion 81 and the board side coupling portion 83 are firmly coupled, and the harness side housing 10d and the board side housing 40d are fixed in a state where relative displacement is restricted. As a result, the terminal fitting 34 and the circuit board 41 are prevented from being subjected to fine sliding wear due to relative displacement in a direction parallel to the plate surface of the circuit board 41.
