Description

コネクタconnector
　本発明は、コネクタに関するものである。 The present invention relates to a connector.
　特許文献１には、端子収容室が形成されたハウジングと、後方から端子収容室に挿入された端子金具とを備えたコネクタが開示されている。ハウジング内には、その前面にスリット状に開口する基板収容空間が形成されており、基板収容空間には、端子金具の前端部に形成した弾性接触部が臨んでいる。基板収容空間内に回路基板が挿入されると、回路基板の接点部に対し弾性接触部が弾性的に当接するようになっている。 Patent Document 1 discloses a connector including a housing in which a terminal accommodating chamber is formed and a terminal fitting inserted into the terminal accommodating chamber from the rear. A substrate housing space that opens in a slit shape is formed in the front surface of the housing, and an elastic contact portion formed at the front end portion of the terminal fitting faces the substrate housing space. When the circuit board is inserted into the board housing space, the elastic contact portion elastically contacts the contact portion of the circuit board.
特開２０１０－１０８６２０号公報JP 2010-108620 A
　端子収容室に挿入された端子金具は、ランスの係止によって抜止めされている。しかし、端子金具の挿入過程ではランスが弾性変形し、端子金具が正規挿入されるランスが弾性復帰して端子金具に係止するようになっている。そのため、端子金具は、端子収容室の前面壁に当接する位置と、ランスに係止する位置との間で、僅かに前後移動し得るようになっている。そのため、端子金具に接続した電線がハウジングの外部で振動した場合、その振動によって端子金具が前後方向に移動し、端子金具の弾性接触片と回路基板の接点部との間で微摺動摩耗が生じることが懸念される。 The terminal fitting inserted in the terminal accommodating chamber is secured by the lance locking. However, the lance is elastically deformed in the process of inserting the terminal fitting, and the lance into which the terminal fitting is normally inserted is elastically restored and locked to the terminal fitting. For this reason, the terminal fitting can be moved back and forth slightly between a position where it contacts the front wall of the terminal accommodating chamber and a position where it is locked to the lance. Therefore, when the electric wire connected to the terminal fitting vibrates outside the housing, the vibration causes the terminal fitting to move in the front-rear direction, causing slight sliding wear between the elastic contact piece of the terminal fitting and the contact portion of the circuit board. I am concerned that it will occur.
　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、ハウジング内における端子金具の不必要な移動を規制することを目的とする。 The present invention has been completed based on the above circumstances, and an object thereof is to restrict unnecessary movement of terminal fittings in a housing.
　本発明は、
　端子収容室が形成されたハウジングと、
　前記ハウジングの後方から前記端子収容室に挿入された端子金具と、
　前記ハウジング内に形成され、前記ハウジングの前面にスリット状に開口する基板収容空間と、
　前記端子金具に形成され、前記基板収容空間に挿入された回路基板に対し弾性的に接触する弾性接触部と、
　前記端子収容室の内壁部に形成された受け部と、
　前記端子金具に形成され、前記受け部に対し前後方向への相対変位が規制された状態で嵌合する嵌合部とを備えているところに特徴を有する。 The present invention
A housing in which a terminal accommodating chamber is formed;
A terminal fitting inserted into the terminal accommodating chamber from the rear of the housing;
A substrate housing space formed in the housing and opening in a slit shape on the front surface of the housing;
An elastic contact portion formed on the terminal fitting and elastically contacting the circuit board inserted into the board housing space;
A receiving portion formed on an inner wall portion of the terminal accommodating chamber;
And a fitting portion that is formed on the terminal fitting and fits in a state where relative displacement in the front-rear direction is restricted with respect to the receiving portion.
　受け部と嵌合部との嵌合により、回路基板に対する端子金具の前後方向への相対変位が規制される。 The relative displacement in the front-rear direction of the terminal fitting with respect to the circuit board is regulated by the fitting between the receiving part and the fitting part.

　本発明は、前記嵌合部が、前記端子金具の外面のうち前記弾性接触部の形成領域とは反対側の領域に配されていてもよい。この構成によれば、弾性接触部が回路基板に弾性接触することにより、嵌合部が受け側に押圧されるので、端子金具の前後方向の移動が、より確実に規制される。 In the present invention, the fitting portion may be arranged in a region opposite to a region where the elastic contact portion is formed on the outer surface of the terminal fitting. According to this configuration, since the elastic contact portion elastically contacts the circuit board, the fitting portion is pressed toward the receiving side, so that the movement of the terminal fitting in the front-rear direction is more reliably regulated.
　本発明は、前記基板収容空間に前記回路基板が未挿入の状態では、前記端子金具が前記嵌合部を前記受け部から離間させる方向へ変位可能であってもよい。この構成によれば、嵌合部を弾性変形させなくても、受け部に嵌合させることができる。 In the present invention, the terminal fitting may be displaceable in a direction in which the fitting portion is separated from the receiving portion in a state where the circuit board is not inserted into the board housing space. According to this configuration, the receiving portion can be fitted without elastically deforming the fitting portion.
　本発明は、前記嵌合部と前記受け部のうち少なくとも一方は、前記嵌合部と前記受け部の嵌合方向に対して傾斜した規制面を有していてもよい。この構成によれば、弾性接触部の弾性復元力により、規制面において嵌合部と受け部が確実に当接するので、端子金具の前後方向への移動が、より確実に規制される。 In the present invention, at least one of the fitting part and the receiving part may have a regulating surface inclined with respect to the fitting direction of the fitting part and the receiving part. According to this configuration, since the fitting portion and the receiving portion abut on the restriction surface reliably by the elastic restoring force of the elastic contact portion, the movement of the terminal fitting in the front-rear direction is more reliably restricted.
　＜実施例１＞
　以下、本発明を具体化した実施例１を図１～図６を参照して説明する。尚、以下の説明において、前後の方向については、図１～４における右方を前方と定義する。上下の方向については、図１～５にあらわれる向きを、そのまま上方、下方と定義する。 <Example 1>
A first embodiment embodying the present invention will be described below with reference to FIGS. In the following description, with respect to the front-rear direction, the right side in FIGS. With respect to the vertical direction, the directions appearing in FIGS. 1 to 5 are defined as “upper” and “lower” as they are.
　本実施例のコネクタＡは、合成樹脂製のハウジング１０と、ハウジング１０内に収容された複数の端子金具３０とを備えて構成されている。ハウジング１０は、ハウジング本体１１と、フロントホルダ１６とを組み付けて構成されている。ハウジング本体１１内には、ハウジング本体１１を前後方向に貫通した形態の端子収容室１２が形成されている。端子収容室１２は、上下に並ぶもの同士が対をなしていて、複数対の端子収容室１２が左右方向に所定ピッチで並列して形成されている。 The connector A of the present embodiment includes a synthetic resin housing 10 and a plurality of terminal fittings 30 accommodated in the housing 10. The housing 10 is configured by assembling a housing body 11 and a front holder 16. A terminal housing chamber 12 is formed in the housing body 11 so as to penetrate the housing body 11 in the front-rear direction. The terminal storage chambers 12 are arranged in pairs in the vertical direction, and a plurality of pairs of terminal storage chambers 12 are formed in parallel at a predetermined pitch in the left-right direction.
　上段側の端子収容室１２には、その上壁面に沿って前方へ片持ち状に延出した形態のランス１３が形成されている。ランス１３には抜止め突起１４が形成されている。ランス１３は、端子収容室１２内に挿入された端子金具３０に抜止め突起１４を係止させることで、端子金具３０を抜止めする。端子収容室１２に端子金具３０が挿入する過程では、端子金具３０と干渉して上方へ弾性変形する。下段側端子収容室１２にも、上段側のランス１３と上下対称なランス１３が形成されている。 In the terminal housing chamber 12 on the upper stage side, a lance 13 having a form extending in a cantilevered manner along the upper wall surface is formed. A retaining protrusion 14 is formed on the lance 13. The lance 13 retains the terminal fitting 30 by engaging the retaining projection 14 with the terminal fitting 30 inserted into the terminal accommodating chamber 12. In the process of inserting the terminal fitting 30 into the terminal accommodating chamber 12, it interferes with the terminal fitting 30 and elastically deforms upward. A lance 13 that is vertically symmetrical with the upper lance 13 is also formed in the lower terminal housing chamber 12.
　また、上段側の端子収容室１２と下段側の端子収容室１２との間には、左右方向に細長く延びたスリット状の基板収容空間１５が形成されている。基板収容空間１５は、ハウジング１０の前端面に開放されているとともに、上下両端子収容室１２の前端部に連通している。基板収容空間１５内には、ハウジング１０の前方から回路基板４０の接続端縁部４０Ｅが挿入されるようになっている。回路基板４０は、基板ホルダ４２に取り付けられている。接続端縁部４０Ｅには、複数の接点部（図示省略）が左右方向に並んで設けられている。接点部の表面（後述する弾性接触部３２との接触面）には、錫メッキ（図示省略）による表面処理が施されている。 Further, a slit-like substrate accommodation space 15 that is elongated in the left-right direction is formed between the upper terminal accommodation chamber 12 and the lower terminal accommodation chamber 12. The substrate housing space 15 is open to the front end surface of the housing 10 and communicates with the front end portions of the upper and lower terminal housing chambers 12. A connection edge 40E of the circuit board 40 is inserted into the board housing space 15 from the front of the housing 10. The circuit board 40 is attached to the board holder 42. A plurality of contact portions (not shown) are provided side by side in the left-right direction on the connection edge 40E. The surface of the contact portion (the contact surface with the elastic contact portion 32 described later) is subjected to a surface treatment by tin plating (not shown).
　フロントホルダ１６は、ハウジング本体１１の前端部に組み付けられている。フロントホルダ１６は、上下両端子収容室１２の前端の開口を、夫々、閉塞する上下対称な一対の前壁部１７を有している。上側の前壁部１７と下側の前壁部１７との間には、基板収容空間１５の前端と連通する横長のスリット状をなす基板挿入口１８が開口している。基板挿入口１８には、回路基板４０の接続端縁部４０Ｅが貫通されるようになっている。フロントホルダ１６は、ハウジング本体１１の外周を包囲する周壁部１９を有している。周壁部１９の前端は前壁部１７に連なっている。周壁部１９には、ランス１３が端子金具３０との干渉によって弾性変形することを許容するための撓み空間２０が形成されている。 The front holder 16 is assembled to the front end portion of the housing body 11. The front holder 16 has a pair of vertically symmetrical front wall portions 17 that respectively close the openings at the front ends of the upper and lower terminal accommodating chambers 12. Between the upper front wall portion 17 and the lower front wall portion 17, a horizontally long slit-shaped substrate insertion opening 18 that communicates with the front end of the substrate housing space 15 is opened. The connection end edge portion 40 </ b> E of the circuit board 40 is penetrated through the board insertion opening 18. The front holder 16 has a peripheral wall portion 19 that surrounds the outer periphery of the housing body 11. The front end of the peripheral wall portion 19 continues to the front wall portion 17. A bending space 20 is formed in the peripheral wall portion 19 to allow the lance 13 to elastically deform due to interference with the terminal fitting 30.
　フロントホルダ１６は、各端子収容室１２と対応する複数の規制部２１を有している。規制部２１は、端子収容室１２の前端部に位置し、端子金具３０を挟んで基板収容空間１５とは反対側に位置している。規制部２１は、前壁部１７から後方へ片持ち状に延出している。規制部２１のうち端子収容室１２に臨む内面は、その全領域に亘り、端子収容室１２に対する端子金具３０の挿入方向と平行な平面となっていて、端子収容室１２の内壁面を構成している。 The front holder 16 has a plurality of restricting portions 21 corresponding to the terminal accommodating chambers 12. The restricting portion 21 is located at the front end portion of the terminal accommodating chamber 12 and is located on the opposite side of the substrate accommodating space 15 with the terminal fitting 30 interposed therebetween. The restricting portion 21 extends in a cantilevered manner from the front wall portion 17 to the rear. The inner surface of the restricting portion 21 facing the terminal accommodating chamber 12 is a plane parallel to the insertion direction of the terminal fitting 30 with respect to the terminal accommodating chamber 12 over the entire area, and constitutes the inner wall surface of the terminal accommodating chamber 12. ing.
　規制部２１の左右両側縁は、隣り合う端子収容室１２を区画する隔壁部に連なっている。これにより、規制部２１は、補強されて変形し難くなっている。また、規制部２１の外面における前端側領域は、前方に向かって端子収容室１２から離間するように傾斜している。したがって、規制部２１の前端側領域の厚さ寸法（上下寸法）は、前方に向かって次第に大きくなり、前壁部１７に連なる前端において最大寸法となっている。この厚さが増大する形状によっても、規制部２１は、補強されて変形し難くなっている。 The left and right side edges of the restricting portion 21 are connected to a partition portion that divides the adjacent terminal accommodating chamber 12. Thereby, the control part 21 is reinforced and becomes difficult to deform | transform. Further, the front end side region on the outer surface of the restricting portion 21 is inclined so as to be separated from the terminal accommodating chamber 12 toward the front. Therefore, the thickness dimension (vertical dimension) of the front end side region of the restricting portion 21 gradually increases toward the front, and is the maximum dimension at the front end connected to the front wall portion 17. Even with the shape in which the thickness increases, the restricting portion 21 is reinforced and hardly deformed.
　規制部２１のうち後端側領域には、受け部２２が形成されている。この受け部２２は、規制部２１を上下方向（端子収容室１２に対する端子金具３０の挿入方向と略直角に交差する方向）に貫通した形態である。規制部２１の内面（端子収容室１２に臨む面）における受け部２２の開口形状は、円形である。受け部２２は、ランス１３の抜止め突起１４よりも前方に配置されている。 The receiving part 22 is formed in the rear end side region of the restricting part 21. The receiving portion 22 has a shape that penetrates the restricting portion 21 in the vertical direction (a direction that intersects the insertion direction of the terminal fitting 30 with respect to the terminal accommodating chamber 12 at a substantially right angle). The opening shape of the receiving portion 22 on the inner surface of the restricting portion 21 (the surface facing the terminal accommodating chamber 12) is circular. The receiving portion 22 is disposed in front of the retaining protrusion 14 of the lance 13.
　端子金具３０は、全体として前後方向に細長い形状である。端子金具３０の後端部には電線３６が接続されている。端子収容室１２の後端部内周と電線３６の外周との間には、防水用のゴム栓３７が設けられている。端子金具３０の前端部には、概ね角筒状をなす端子本体部３１が形成されている。端子本体部３１の外周面のうち基板収容空間１５に臨む領域には、基板収容空間１５に挿入された回路基板４０の接点部に弾性接触する弾性接触部３２が形成されている。弾性接触部３２を含む端子金具３０の表面（前述の接点部との接触面）には、錫メッキ（図示省略）による表面処理が施されている。 The terminal fitting 30 has an elongated shape in the front-rear direction as a whole. An electric wire 36 is connected to the rear end portion of the terminal fitting 30. A waterproof rubber plug 37 is provided between the inner periphery of the rear end of the terminal accommodating chamber 12 and the outer periphery of the electric wire 36. A terminal body 31 having a generally rectangular tube shape is formed at the front end of the terminal fitting 30. An elastic contact portion 32 that elastically contacts the contact portion of the circuit board 40 inserted into the substrate housing space 15 is formed in an area facing the substrate housing space 15 in the outer peripheral surface of the terminal main body portion 31. The surface of the terminal fitting 30 including the elastic contact portion 32 (contact surface with the contact portion described above) is subjected to surface treatment by tin plating (not shown).
　端子本体部３１の外周面のうち基板収容空間１５に臨む領域とは反対側の領域には、段差状の係止部３３が形成されている。端子収容室１２に端子金具３０が挿入される過程では、端子本体部３１の外面が抜止め突起１４と干渉することにより、ランス１３が端子収容室１２から退避するように弾性変位する。そして、端子金具３０が正規挿入位置に到達すると、端子本体部３１の前端が前壁部１７に当接することにより、端子金具３０が前止まりされる。 A stepped locking portion 33 is formed in a region on the opposite side of the outer peripheral surface of the terminal main body 31 from the region facing the substrate housing space 15. In the process of inserting the terminal fitting 30 into the terminal accommodating chamber 12, the outer surface of the terminal main body 31 interferes with the retaining protrusion 14, so that the lance 13 is elastically displaced so as to retract from the terminal accommodating chamber 12. When the terminal fitting 30 reaches the normal insertion position, the front end of the terminal main body 31 comes into contact with the front wall portion 17, so that the terminal fitting 30 is stopped in front.
　端子金具３０が前止まりされると、ほぼ同時に、係止部３３が抜止め突起１４を通過し終わるので、ランス１３が弾性復帰し、抜止め突起１４が係止部３３に対して係止可能となる。この係止作用により、端子金具３０が抜止めされる。尚、端子収容室１２の前端部は基板収容空間１５に連通しているため、端子金具３０が正規挿入された状態では、端子金具３０の前端部（端子本体部３１）が、基板収容空間１５側へ傾くように上下方向へ変位し得るようになっている。しかし、その変位の許容量は、抜止め突起１４と係止部３３との係止代よりも小さいので、端子金具３０がランス１３から外れて後方へ離脱する虞はない。 When the terminal fitting 30 is stopped in front, the locking portion 33 finishes passing through the retaining projection 14 almost simultaneously, so that the lance 13 is elastically restored and the retaining projection 14 can be locked to the locking portion 33. It becomes. By this locking action, the terminal fitting 30 is prevented from being pulled out. Since the front end portion of the terminal accommodating chamber 12 communicates with the substrate accommodating space 15, the front end portion (terminal main body portion 31) of the terminal fitting 30 is in the substrate accommodating space 15 when the terminal fitting 30 is properly inserted. It can be displaced in the vertical direction so as to tilt to the side. However, since the allowable amount of displacement is smaller than the locking allowance between the retaining protrusion 14 and the locking portion 33, there is no possibility that the terminal fitting 30 is detached from the lance 13 and detached backward.
　また、ランス１３はその後端部を支点として姿勢を傾けるように変形するため、抜止め突起１４の軌跡は、端子金具３０の挿入方向（前後方向）と直角な直線状の軌跡ではなく、円弧状の軌跡を描く。そのため、ランス１３が端子金具３０を抜止めしている状態では、端子金具３０が、端子本体部３１の前端を前壁部１７に当接させる位置と、係止部３３を抜止め突起１４に当接させる位置との間で、僅かではあるがハウジング１０に対して前後方向へ相対的に変位し得る。 Further, since the lance 13 is deformed so that its posture is inclined with its rear end as a fulcrum, the locus of the retaining protrusion 14 is not a linear locus perpendicular to the insertion direction (front-rear direction) of the terminal fitting 30 but an arc shape. Draw a trajectory. Therefore, in a state where the lance 13 keeps the terminal metal fitting 30 from being removed, the terminal metal fitting 30 has a position where the front end of the terminal main body portion 31 abuts against the front wall portion 17, and the locking portion 33 at the retaining protrusion 14. The position can be relatively displaced relative to the housing 10 in the front-rear direction with respect to the abutting position.
　そのため、ハウジング１０の後方へ引き出されている電線３６が振動すると、端子金具３０が前後方向に往復移動し、回路基板４０の接点部と端子金具３０の弾性接触部３２との間で微摺動摩耗が生じることが懸念される。この対策として、本実施例のコネクタＡは、上記の受け部２２と、後述する嵌合部３４とを備えている。以下、嵌合部３４について説明する。 Therefore, when the electric wire 36 drawn to the rear of the housing 10 vibrates, the terminal fitting 30 reciprocates in the front-rear direction, and slightly slides between the contact portion of the circuit board 40 and the elastic contact portion 32 of the terminal fitting 30. There is a concern that wear may occur. As a countermeasure, the connector A of this embodiment includes the receiving portion 22 and a fitting portion 34 described later. Hereinafter, the fitting portion 34 will be described.
　嵌合部３４の形成位置は、端子本体部３１の外周面のうち基板収容空間１５に臨む領域とは反対側の領域の前端部である。つまり、嵌合部３４は、係止部３３よりも前方であって、受け部２２と対応する位置に配されている。嵌合部３４は、端子本体部３１を構成する壁部の一部を外面側（基板収容空間１５とは反対側）へ叩き出しにより突出させた形態である。嵌合部３４は、略球面状をなしており、嵌合部３４の最大外径は、フロントホルダ１６の受け部２２の内径よりも僅かに大きい寸法となっている。 The forming position of the fitting part 34 is the front end part of the area on the opposite side of the outer peripheral surface of the terminal main body 31 from the area facing the board housing space 15. That is, the fitting portion 34 is disposed in front of the locking portion 33 and at a position corresponding to the receiving portion 22. The fitting part 34 is a form in which a part of the wall part constituting the terminal main body part 31 is protruded to the outer surface side (the side opposite to the board housing space 15). The fitting portion 34 has a substantially spherical shape, and the maximum outer diameter of the fitting portion 34 is slightly larger than the inner diameter of the receiving portion 22 of the front holder 16.
　端子金具３０が正規挿入された状態では、嵌合部３４が、受け部２２に対し端子収容室１２側から嵌入されるようになっている。嵌合部３４の外面は、規制面３５となっている。規制面３５の側面視形状は、略円弧形をなしている。この側面視形状は、規制面３５を、端子収容室１２に対する端子金具３０の挿入方向と、受け部２２に対する嵌合部３４の嵌合方向との両方向に対して交差する方向から視た形状である。 When the terminal fitting 30 is properly inserted, the fitting portion 34 is inserted into the receiving portion 22 from the terminal accommodating chamber 12 side. The outer surface of the fitting portion 34 is a restriction surface 35. The side view shape of the restriction surface 35 has a substantially arc shape. This side view shape is a shape in which the regulating surface 35 is viewed from a direction intersecting both directions of the insertion direction of the terminal fitting 30 with respect to the terminal accommodating chamber 12 and the fitting direction of the fitting portion 34 with respect to the receiving portion 22. is there.
　側面視形状は略円弧形であるから、規制面３５のうち突出端以外の領域は、嵌合部３４と受け部２２の嵌合方向（上下方向）に対して傾斜している。そして、側面視において、規制面３５の前縁部と後縁部の前後寸法は、嵌合部３４の突出方向に向かって次第に小さくなっている。そして、嵌合部３４と受け部２２が嵌合した状態では、規制面３５が、規制部２１の内面における受け部２２の開口縁に対しほぼ全周に亘って当接するようになっている。また、嵌合状態において、受け部２２に対する嵌合部３４の嵌入深さは、端子本体部３１が基板収容空間１５側へ変位し得る最大寸法よりも小さい寸法とされている。 Since the shape in a side view is a substantially arc shape, the region other than the projecting end of the regulation surface 35 is inclined with respect to the fitting direction (vertical direction) of the fitting portion 34 and the receiving portion 22. In the side view, the front and rear dimensions of the front edge portion and the rear edge portion of the restriction surface 35 are gradually reduced toward the protruding direction of the fitting portion 34. And in the state which the fitting part 34 and the receiving part 22 fitted, the control surface 35 contact | abuts to the opening edge of the receiving part 22 in the inner surface of the control part 21 over a perimeter. Further, in the fitted state, the fitting depth of the fitting part 34 with respect to the receiving part 22 is set to a dimension smaller than the maximum dimension at which the terminal main body part 31 can be displaced toward the board housing space 15 side.
　次に、本実施例の作用を説明する。端子金具３０が端子収容室１２内に正規挿入された状態では、上段側の端子収容室１２に挿入されている端子金具３０の端子本体部３１は、自重によって基板収容空間１５側へ変位する。しかし、このとき係止部３３は抜止め突起１４から外れることがないので、端子金具３０はランス１３によって抜止め状態に保たれる。また、嵌合部３４は、受け部２２から外れているが、受け部２２のほぼ真下の近傍位置に配される。 Next, the operation of this embodiment will be described. In a state where the terminal fitting 30 is normally inserted into the terminal accommodating chamber 12, the terminal main body portion 31 of the terminal fitting 30 inserted into the upper terminal accommodating chamber 12 is displaced toward the substrate accommodating space 15 by its own weight. However, at this time, since the locking portion 33 does not come off from the retaining projection 14, the terminal fitting 30 is kept in the retaining state by the lance 13. In addition, the fitting portion 34 is disengaged from the receiving portion 22, but is disposed at a position near the receiving portion 22.
　一方、下段側の端子金具３０については、端子本体部３１が基板収容空間１５側へ変位することがない。したがって、端子金具３０はランス１３によって抜止め状態に保持されるとともに、嵌合部３４が受け部２２に嵌合した状態となっている。 On the other hand, with respect to the lower terminal fitting 30, the terminal body 31 is not displaced toward the board housing space 15 side. Accordingly, the terminal fitting 30 is held in the retaining state by the lance 13, and the fitting portion 34 is fitted to the receiving portion 22.
　端子収容室１２に端子金具３０を挿入した後は、回路基板４０の接続端縁部４０Ｅを、ハウジング１０の前端面に開口する基板挿入口１８に挿し込んで基板収容空間１５内に収容する。すると、接続端縁部４０Ｅは、上段側の弾性接触部３２と下段側の弾性接触部３２との間に割り込むので、上段側の端子金具３０が上方へ変位し、その嵌合部３４が受け部２２に嵌入される。このとき、上段側の弾性接触部３２と下段側の弾性接触部３２が両方共に弾性変形させられるので、両弾性接触部３２の弾性復元力により、上下両方の嵌合部３４の規制面３５が、受け部２２の開口縁に対して強く押し付けられる。 After the terminal fitting 30 is inserted into the terminal accommodating chamber 12, the connection edge 40 </ b> E of the circuit board 40 is inserted into the board insertion opening 18 that opens at the front end surface of the housing 10 and is accommodated in the board accommodating space 15. Then, since the connecting edge 40E is inserted between the upper elastic contact portion 32 and the lower elastic contact portion 32, the upper terminal fitting 30 is displaced upward, and the fitting portion 34 receives the connection end portion 40E. It is inserted into the part 22. At this time, since both the upper elastic contact portion 32 and the lower elastic contact portion 32 are elastically deformed, the restricting surfaces 35 of the upper and lower fitting portions 34 are caused by the elastic restoring force of both elastic contact portions 32. , And strongly pressed against the opening edge of the receiving portion 22.
　これにより、嵌合部３４と受け部２２が、前後方向への相対変位を規制された状態で嵌合される。そして、この嵌合により、電線３６が振動したとしても、ハウジング１０に対する端子金具３０の前後方向への相対変位が規制されるので、弾性接触部３２と回路基板４０の接点部との間の微摺動摩耗が防止される。また、回路基板４０の接点部と端子金具３０（弾性接触部３２）との接触面には錫メッキが施されているのであるが、上記のように接点部と弾性接触部３２との間での微摺動摩耗が抑えられているので、比較的安価な錫メッキであっても接触不良を生じる虞はない。このように、接点部と弾性接触部３２との接触面には高価な金メッキを施さずに済んでいるので、コスト低減が実現されている。 Thereby, the fitting part 34 and the receiving part 22 are fitted in a state where relative displacement in the front-rear direction is restricted. And even if the electric wire 36 vibrates by this fitting, since the relative displacement in the front-rear direction of the terminal fitting 30 with respect to the housing 10 is restricted, the minute contact between the elastic contact portion 32 and the contact portion of the circuit board 40 is restricted. Sliding wear is prevented. Further, the contact surface between the contact portion of the circuit board 40 and the terminal fitting 30 (elastic contact portion 32) is tin-plated, but as described above, between the contact portion and the elastic contact portion 32. Therefore, there is no risk of contact failure even with relatively inexpensive tin plating. In this way, the contact surface between the contact portion and the elastic contact portion 32 does not have to be subjected to expensive gold plating, so that cost reduction is realized.
　本実施例のコネクタＡは、端子収容室１２が形成されたハウジング１０と、ハウジング１０の後方から端子収容室１２に挿入された端子金具３０とを備えている。ハウジング１０内には、ハウジング１０の前面において基板挿入口１８を介してスリット状に開口する基板収容空間１５が形成され、端子金具３０には、基板収容空間１５に挿入された回路基板４０の接続端縁部４０Ｅに対し弾性的に接触する弾性接触部３２が形成されている。また、端子収容室１２の内壁部には受け部２２が形成され、端子金具３０には、受け部２２に対し前後方向への相対変位が規制された状態で嵌合する嵌合部３４が形成されている。この構成によれば、受け部２２と嵌合部３４との嵌合により、回路基板４０に対する端子金具３０の前後方向への相対変位を防止することができる。 The connector A of the present embodiment includes a housing 10 in which the terminal accommodating chamber 12 is formed, and a terminal fitting 30 inserted into the terminal accommodating chamber 12 from the rear of the housing 10. In the housing 10, a substrate housing space 15 that opens in a slit shape through the substrate insertion opening 18 is formed on the front surface of the housing 10, and connection of the circuit board 40 inserted in the substrate housing space 15 is connected to the terminal fitting 30. An elastic contact portion 32 that elastically contacts the edge portion 40E is formed. In addition, a receiving portion 22 is formed on the inner wall portion of the terminal accommodating chamber 12, and a fitting portion 34 is formed on the terminal fitting 30 to be fitted in a state where relative displacement in the front-rear direction is restricted with respect to the receiving portion 22. Has been. According to this configuration, the relative displacement in the front-rear direction of the terminal fitting 30 with respect to the circuit board 40 can be prevented by the fitting of the receiving portion 22 and the fitting portion 34.
　また、嵌合部３４は、端子金具３０の外面のうち弾性接触部３２が形成されている領域（基板収容空間１５に臨む領域）とは反対側の領域に配されている。この構成によれば、弾性接触部３２が回路基板４０に弾性接触することにより、嵌合部３４が受け側に押圧されるので、端子金具３０の前後方向の移動が、より確実に規制される。また、基板収容空間１５に回路基板４０が未挿入の状態では、端子金具３０が嵌合部３４を受け部２２から離間させる方向へ変位可能となっている。この構成によれば、嵌合部３４を弾性変形させなくても、受け部２２と嵌合部３４とを嵌合させることができる。また、嵌合部３４は、嵌合部３４と受け部２２の嵌合方向に対して傾斜した規制面３５を有している。この構成によれば、弾性接触部３２の弾性復元力により、規制面３５において嵌合部３４と受け部２２が確実に当接するので、端子金具３０の前後方向に移動が、より確実に規制される。 Further, the fitting portion 34 is disposed in a region on the opposite side of the outer surface of the terminal fitting 30 from the region where the elastic contact portion 32 is formed (the region facing the substrate housing space 15). According to this configuration, since the elastic contact portion 32 elastically contacts the circuit board 40, the fitting portion 34 is pressed to the receiving side, so that the movement of the terminal fitting 30 in the front-rear direction is more reliably regulated. . Further, when the circuit board 40 is not inserted into the board housing space 15, the terminal fitting 30 can be displaced in a direction in which the fitting part 34 is separated from the receiving part 22. According to this configuration, the receiving portion 22 and the fitting portion 34 can be fitted without the fitting portion 34 being elastically deformed. The fitting portion 34 has a regulating surface 35 that is inclined with respect to the fitting direction of the fitting portion 34 and the receiving portion 22. According to this configuration, the elastic restoring force of the elastic contact portion 32 ensures that the fitting portion 34 and the receiving portion 22 come into contact with each other on the restriction surface 35, so that movement of the terminal fitting 30 in the front-rear direction is more reliably restricted.
