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
　弾性接触部は、回路基板に対して確実に弾性接触させる必要があるため、回路基板が基板収容空間に挿入されていない状態で、基板収容空間内に進出している。一方、端子収容室の前端部においては、端子収容室に対する端子金具の挿入を円滑に行えるようにする手段として、端子収容室の内壁面と端子金具の外面との間にクリアランスを確保している。 Since the elastic contact portion needs to be surely brought into elastic contact with the circuit board, the circuit board has advanced into the board housing space without being inserted into the board housing space. On the other hand, at the front end portion of the terminal receiving chamber, a clearance is secured between the inner wall surface of the terminal receiving chamber and the outer surface of the terminal fitting as a means for smoothly inserting the terminal fitting into the terminal receiving chamber. .
　そのため、基板収容空間より上側に端子金具が配置されている場合に、その端子金具が、自重によりクリアランスの範囲内で下方へ変位し、その結果、基板収容空間内への弾性接触部の進出量が大きくなる。弾性接触部の進出量が大きくなると、基板収容空間に回路基板を挿入する際に、回路基板の挿入端部が大きく進出している弾性接触部に引っ掛かり、挿入作業に支障を来す虞がある。 Therefore, when the terminal fitting is disposed above the board housing space, the terminal fitting is displaced downward within the clearance due to its own weight, and as a result, the amount of advancement of the elastic contact portion into the board housing space Becomes larger. If the amount of advancement of the elastic contact portion becomes large, when the circuit board is inserted into the board housing space, the insertion end of the circuit board may be caught by the elastic contact portion that has advanced greatly, which may hinder the insertion work. .
　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、ハウジングに対する回路基板の円滑な挿入を実現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 realize smooth insertion of a circuit board into 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、
　前記端子収容室の前端部に形成され、前記端子収容室内に挿入した前記端子金具を当接させる前壁部と、
　前記前壁部に形成された受け部と、
　前記端子金具の前端面に形成され、前記受け部に対し前記基板収容空間側への相対変位を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 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 the front wall portion;
And a fitting portion that is formed on a front end surface of the terminal fitting and is fitted to the receiving portion in a state in which relative displacement toward the substrate housing space is restricted.
　受け部と嵌合部との嵌合により、弾性接触部が基板収容空間側へ大きく進出することを規制しているので、回路基板が、基板収容空間への挿入過程で弾性接触部に突き当たる虞がなく、回路基板をハウジング内に円滑に挿入することができる。 Since the elastic contact portion is largely prevented from advancing toward the board housing space due to the fitting between the receiving portion and the fitting portion, the circuit board may hit the elastic contact portion during the insertion process into the board housing space. The circuit board can be smoothly inserted into the housing.

　＜実施例１＞
　以下、本発明を具体化した実施例１を図１～図４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１～３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１～４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. 1 to 3 is defined as the front. With respect to the up and down directions, the directions appearing in FIGS.
　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１２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１３が形成されている。端子収容室１３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１３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 main body 11 and a front holder 12. A terminal accommodating chamber 13 is formed in the housing body 11 so as to penetrate the housing body 11 in the front-rear direction. The terminal accommodating chambers 13 are arranged in pairs in the vertical direction, and a plurality of pairs of terminal accommodating chambers 13 are formed in parallel at a predetermined pitch in the left-right direction.
　上段側の端子収容室１３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１４が形成されている。ランス１４には抜止め突起１５が形成されている。ランス１４は、端子収容室１３内に挿入された端子金具３０に抜止め突起１５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１３に端子金具３０が挿入する過程では、ランス１４が端子金具３０と干渉して上方へ弾性変形する。下段側端子収容室１３にも、上段側のランス１４と上下対称なランス１４が形成されている。 A lance 14 having a form extending in a cantilevered manner along the upper wall surface is formed in the upper terminal housing chamber 13. A retaining protrusion 15 is formed on the lance 14. The lance 14 retains the terminal fitting 30 by engaging the retaining protrusion 15 with the terminal fitting 30 inserted into the terminal accommodating chamber 13. In the process of inserting the terminal fitting 30 into the terminal accommodating chamber 13, the lance 14 interferes with the terminal fitting 30 and elastically deforms upward. A lance 14 that is vertically symmetrical with the upper lance 14 is also formed in the lower terminal housing 13.
　また、上段側の端子収容室１３と下段側の端子収容室１３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１６が形成されている。基板収容空間１６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１３の前端部に連通している。基板収容空間１６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４１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。 Further, a slit-like substrate accommodation space 16 that is elongated in the left-right direction is formed between the upper terminal accommodation chamber 13 and the lower terminal accommodation chamber 13. The substrate housing space 16 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 13. A connection edge 40E of the circuit board 40 is inserted into the board housing space 16 from the front of the housing 10. The circuit board 40 is attached to the board holder 41. A plurality of contact portions (not shown) are provided side by side in the left-right direction on the connection edge 40E.
　フロントホルダ１２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１２は、上下両端子収容室１３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１６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１２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１４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 12 is assembled to the front end portion of the housing body 11. The front holder 12 has a pair of vertically symmetrical front wall portions 17 that close the openings at the front ends of the upper and lower terminal accommodating chambers 13 respectively. Between the upper front wall portion 17 and the lower front wall portion 17, a substrate insertion port 18 having a horizontally long slit shape communicating with the front end of the substrate housing space 16 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 12 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 14 to be elastically deformed by interference with the terminal fitting 30.
　前壁部１７には、複数の受け部２１が形成されている。この受け部２１は、前壁部１７を前後方向（端子収容室１３に対する端子金具３０の挿入方向と略平行な方向）に貫通した形態である。受け部２１の前端は、ハウジング１０（フロントホルダ１２）の前端面に開口している。前壁部１７の後面（端子収容室１３に臨む面）における受け部２１の開口形状は、円形である。 A plurality of receiving portions 21 are formed on the front wall portion 17. The receiving portion 21 has a form penetrating the front wall portion 17 in the front-rear direction (a direction substantially parallel to the insertion direction of the terminal fitting 30 with respect to the terminal accommodating chamber 13). The front end of the receiving portion 21 is open to the front end surface of the housing 10 (front holder 12). The opening shape of the receiving portion 21 on the rear surface of the front wall portion 17 (the surface facing the terminal accommodating chamber 13) is circular.
　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３５が接続されている。端子収容室１３の後端部内周と電線３５の外周との間には、防水用のゴム栓３６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１６に臨む領域とは反対側の領域には、段差状の係止部３２が形成されている。 The terminal fitting 30 has an elongated shape in the front-rear direction as a whole. An electric wire 35 is connected to the rear end of the terminal fitting 30. A waterproof rubber plug 36 is provided between the inner periphery of the rear end of the terminal accommodating chamber 13 and the outer periphery of the electric wire 35. A terminal body 31 having a generally rectangular tube shape is formed at the front end of the terminal fitting 30. A stepped locking portion 32 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 16.
　端子収容室１３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１５と干渉することにより、ランス１４が端子収容室１３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。端子金具３０が前止まりされると、ほぼ同時に、係止部３２が抜止め突起１５を通過し終わるので、ランス１４が弾性復帰し、抜止め突起１５が係止部３２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。 In the process of inserting the terminal fitting 30 into the terminal accommodating chamber 13, the outer surface of the terminal main body 31 interferes with the retaining projection 15, so that the lance 14 is elastically displaced so as to retract from the terminal accommodating chamber 13. 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. When the terminal fitting 30 is stopped in front, the locking portion 32 finishes passing through the retaining projection 15 almost simultaneously, so that the lance 14 is elastically restored and the retaining projection 15 can be locked to the locking portion 32. It becomes. By this locking action, the terminal fitting 30 is prevented from being pulled out.
　尚、端子収容室１３の前端部においては、端子収容室１３に対して端子本体部３１が引っ掛かりなく挿入し得るようにするため端子収容室１３の内面と端子本体部３１の外面との間上下方向のクリアランスが確保されている。このクリアランスにより、端子本体部３１は、僅かではあるがハウジング１０（端子収容室１３）に対して上下方向へ相対変位し得るようになっている。この相対変位の方向は、基板収容空間１６に対して端子本体部３１が接近・離間する方向である。 Note that, at the front end portion of the terminal accommodating chamber 13, the terminal main body 31 is vertically inserted between the inner surface of the terminal accommodating chamber 13 and the outer surface of the terminal main body 31 so that the terminal main body 31 can be inserted into the terminal accommodating chamber 13 without being caught. Directional clearance is ensured. Due to this clearance, the terminal main body 31 can be displaced relatively in the vertical direction with respect to the housing 10 (terminal housing chamber 13), although it is slight. The direction of this relative displacement is a direction in which the terminal body 31 approaches and separates from the board housing space 16.
　端子本体部３１の外周面のうち基板収容空間１６に臨む領域には、基板収容空間１６側へ突出した形態の弾性接触部３３が形成されている。弾性接触部３３は、基板収容空間１６に挿入された回路基板４０の接点部に対し弾性的に接触する。基板収容空間１６に回路基板４０が挿入されていない状態では、弾性接触部３３の一部が基板収容空間１６内に進出している。上記のように端子収容室１３と端子金具３０との間のクリアランスにより、端子本体部３１が端子収容室１３に対して基板収容空間１６側へ相対変位すると、基板収容空間１６に対する弾性接触部３３の進出量が増減する。 The elastic contact part 33 of the form protruded to the board | substrate accommodation space 16 side is formed in the area | region which faces the board | substrate accommodation space 16 among the outer peripheral surfaces of the terminal main-body part 31. FIG. The elastic contact portion 33 elastically contacts the contact portion of the circuit board 40 inserted into the substrate housing space 16. In a state where the circuit board 40 is not inserted into the board housing space 16, a part of the elastic contact portion 33 has advanced into the board housing space 16. As described above, when the terminal main body portion 31 is relatively displaced toward the substrate housing space 16 with respect to the terminal housing chamber 13 by the clearance between the terminal housing chamber 13 and the terminal fitting 30, the elastic contact portion 33 with respect to the substrate housing space 16. The amount of advancement increases or decreases.
　基板収容空間１６への弾性接触部３３の進出量が増大すると、基板収容空間１６に回路基板４０を挿入する過程で、回路基板４０の接続端縁部４０Ｅが弾性接触部３３に突き当たり、挿入動作に支障を来すことが懸念される。そこで、本実施例では、その対策として、上記受け部２１と、後述する嵌合部３４とを設けている。 When the amount of advancement of the elastic contact portion 33 into the board housing space 16 increases, in the process of inserting the circuit board 40 into the board housing space 16, the connection edge 40E of the circuit board 40 abuts against the elastic contact portion 33 and the insertion operation is performed. There is a concern that it will cause trouble. Therefore, in the present embodiment, as the countermeasure, the receiving portion 21 and a fitting portion 34 described later are provided.
　嵌合部３４は、端子本体部３１の前端面に配されている。つまり、嵌合部３４は、端子金具３０が端子収容室１３に正規挿入された状態で、前壁部１７の受け部２１に対し接近して対向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前方（前壁部１７に接近する方向）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、受け部２１の内径よりも僅かに大きい寸法となっている。 The fitting part 34 is arranged on the front end face of the terminal body part 31. That is, the fitting portion 34 is disposed at a position that is close to and faces the receiving portion 21 of the front wall portion 17 in a state where the terminal fitting 30 is normally inserted into the terminal accommodating chamber 13. The fitting part 34 is a form in which a part of the wall part constituting the terminal main body part 31 is protruded forward (in a direction approaching the front wall part 17) by being knocked out. 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 21.
　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１３内に正規挿入された状態では、上段側の端子収容室１３に挿入されている端子金具３０の端子本体部３１が、自重によって基板収容空間１６側へ変位しようとする。しかし、端子本体部３１の前端においては、その嵌合部３４が受け部２１内に嵌入し、前壁部１７の後面（端子収容室１３に臨む面）における受け部２１の開口縁に対し、嵌合部３４が上から係止するので、端子本体部３１の下方への変位が規制される。これにより、基板収容空間１６内への弾性接触部３３の進出量が適正寸法の範囲内に保たれる。 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 13, the terminal main body portion 31 of the terminal fitting 30 inserted into the upper terminal accommodating chamber 13 tends to be displaced toward the substrate accommodating space 16 by its own weight. To do. However, at the front end of the terminal body 31, the fitting portion 34 is fitted into the receiving portion 21, and the opening edge of the receiving portion 21 on the rear surface of the front wall portion 17 (the surface facing the terminal accommodating chamber 13), Since the fitting portion 34 is locked from above, the downward displacement of the terminal main body portion 31 is restricted. Thereby, the advance amount of the elastic contact portion 33 into the substrate housing space 16 is maintained within a range of appropriate dimensions.
　端子収容室１３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に挿し込み、基板収容空間１６内に収容する。このとき、基板収容空間１６内に対する弾性接触部３３の進出量が適正寸法の範囲内に保たれているので、接続端縁部４０Ｅが弾性接触部３３に突き当たったり引っ掛かったりすることはない。回路基板４０が基板収容空間１６内に円滑に挿入されると、接続端縁部４０Ｅが、上段側の弾性接触部３３と下段側の弾性接触部３３との間に割り込み、上下両弾性接触部３３が弾性変形させられる。この両弾性接触部３３の弾性復元力により、弾性接触部３３と回路基板４０の接点部とが適正な接触圧で接続される。 After the terminal fitting 30 is inserted into the terminal accommodating chamber 13, 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 16. At this time, since the amount of advancement of the elastic contact portion 33 with respect to the inside of the substrate housing space 16 is maintained within a range of an appropriate size, the connection end edge portion 40E does not hit or get caught by the elastic contact portion 33. When the circuit board 40 is smoothly inserted into the board accommodating space 16, the connection edge 40E interrupts between the upper elastic contact part 33 and the lower elastic contact part 33, and both upper and lower elastic contact parts. 33 is elastically deformed. Due to the elastic restoring force of both elastic contact portions 33, the elastic contact portion 33 and the contact portion of the circuit board 40 are connected with an appropriate contact pressure.
　本実施例のコネクタＡは、端子収容室１３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１３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１６が形成され、端子金具３０には、基板収容空間１６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３３が形成されている。また、端子収容室１３の前端部には、端子収容室１３内に挿入した端子金具３０を当接して前止まりさせる前壁部１７が形成されている。 The connector A of the present embodiment includes a housing 10 in which a terminal accommodating chamber 13 is formed, and a terminal fitting 30 inserted into the terminal accommodating chamber 13 from the rear of the housing 10. In the housing 10, a board housing space 16 that opens in a slit shape is formed on the front surface of the housing 10 through the board insertion opening 18, and the terminal fitting 30 is connected to the circuit board 40 inserted in the board housing space 16. An elastic contact portion 33 that elastically contacts the end edge portion 40E is formed. In addition, a front wall portion 17 is formed at the front end portion of the terminal accommodating chamber 13 so that the terminal fitting 30 inserted into the terminal accommodating chamber 13 is brought into contact with and stopped in front.
　そして、前壁部１７には受け部２１が形成されている。端子金具３０の前端面には、受け部２１に対し基板収容空間１６側への相対変位を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２１と嵌合部３４との嵌合により、弾性接触部３３が基板収容空間１６側へ大きく進出することを規制しているので、回路基板４０が、基板収容空間１６への挿入過程で弾性接触部３３に突き当たる虞がない。これにより、回路基板４０をハウジング１０内に円滑に挿入することができる。 And the receiving part 21 is formed in the front wall part 17. A fitting portion 34 is formed on the front end surface of the terminal fitting 30 to be fitted to the receiving portion 21 in a state where relative displacement toward the substrate housing space 16 is restricted. According to this configuration, the elastic contact portion 33 is largely prevented from advancing toward the substrate housing space 16 by the fitting of the receiving portion 21 and the fitting portion 34, so that the circuit board 40 is placed in the substrate housing space. There is no possibility of hitting the elastic contact portion 33 in the process of insertion into 16. Thereby, the circuit board 40 can be smoothly inserted into the housing 10.
　また、受け部２１は、前壁部１７を貫通してハウジング１０の前端面に開口した形態である。嵌合部３４は、突起状をなして受け部２１内に嵌入されている。この構成によれば、ハウジング１０の前方からプローブＰを挿入して嵌合部３４に当接させることにより、導通検査を行うことができる。 Further, the receiving portion 21 has a form that penetrates through the front wall portion 17 and opens to the front end surface of the housing 10. The fitting part 34 is fitted into the receiving part 21 in a protruding shape. According to this configuration, the continuity test can be performed by inserting the probe P from the front of the housing 10 and bringing it into contact with the fitting portion 34.
