Description

本発明は、コネクタに関する。 The present invention relates to a connector.

従来、端子金具と、端子金具を収容させる筐体と、この筐体の中で端子金具に対して物理的且つ電気的に接続され、かつ、筐体の外に引き出されるシート状の導電部材｛例えば、フレキシブルプリント回路基板（所謂ＦＰＣ）等｝と、を備えるコネクタについて知られている。この種のコネクタは、例えば、下記の特許文献１に開示されている。 Conventionally, a terminal metal fitting, a casing for housing the terminal metal fitting, and a sheet-like conductive member that is physically and electrically connected to the terminal fitting inside the casing and drawn out of the casing { For example, connectors comprising a flexible printed circuit board (so-called FPC), etc. are known. This type of connector is disclosed in, for example, Patent Document 1 below.

このような構成から成るコネクタにおいては、端子金具の導体接続部と導電部材の電気接続部とが接続可能な状態に配置された上で、その導体接続部と電気接続部とが半田付け等の接続工程を経て固着される。例えば、このコネクタにおいては、筐体に収容された端子金具の導体接続部を筐体の外に突出させ、その導体接続部を導電部材の電気接続部としての導体接続用の貫通孔（所謂スルーホール）に挿通させる。このようにして、端子金具と導電部材は、導体接続部とスルーホールとの接続作業が可能な状態に配置される。そして、このコネクタにおいては、その状態で導体接続部とスルーホールとの間の接続作業が実施される。このようなコネクタにおいては、一般に複数の端子金具が筐体に収容されている。 In a connector with such a configuration, the conductor connection part of the terminal fitting and the electrical connection part of the conductive member are arranged in a connectable state, and then the conductor connection part and the electrical connection part are connected by soldering etc. It is fixed through a connection process. For example, in this connector, the conductor connection part of the terminal fitting housed in the housing protrudes outside the housing, and the conductor connection part is used as the electrical connection part of the conductive member through a through hole (so-called through hole) for conductor connection. hole). In this way, the terminal fitting and the conductive member are arranged in such a state that the conductor connecting portion and the through hole can be connected. In this connector, the connection work between the conductor connection portion and the through hole is performed in this state. In such a connector, a plurality of terminal fittings are generally housed in a housing.

ところで、このようなコネクタにおいては、筐体の外に引き出させるだけの長さに導電部材が形成されているので、その導電部材のスルーホールに端子金具の導体接続部を挿し入れながら、筐体及び端子金具に対する導電部材の設置作業を行っているときに、又は、その設置作業を終えて、導体接続部とスルーホールとの接続作業が可能な状態になっているときに、その導電部材における筐体からの引出領域が作業者に引っ張られてしまう可能性がある。そして、このコネクタにおいては、その製造工程で発生した引っ張りに伴う力が端子金具の導体接続部と導電部材におけるスルーホールの周縁部との間に作用すると、その力の大きさや方向如何で、端子金具や導電部材の品質を低下させてしまう可能性がある。よって、従来のコネクタにおいては、筐体に設けた係止突起を導電部材に設けた係止孔に挿通させ、引っ張りに伴う力を係止突起と導電部材における係止孔の周縁部との間で受けさせることによって、端子金具の導体接続部と導電部材におけるスルーホールの周縁部との間への力の伝達を抑えている。しかしながら、このコネクタにおいては、結局のところ、係止突起と導電部材における係止孔の周縁との間で引っ張りに伴う力を受けることになるので、その力の大きさや方向如何で、筐体や導電部材の品質を低下させてしまう虞がある。従って、このコネクタにおいては、品質の低下の有無の確認を製造工程の中で簡便に実施できるようにしておくことが望ましい。 By the way, in such a connector, the conductive member is formed long enough to be pulled out of the casing, so while inserting the conductor connection part of the terminal fitting into the through hole of the conductive member, insert the conductive member into the casing. and when the conductive member is being installed on the terminal fitting, or when the conductor connection part and the through hole can be connected after the installation work, the conductive member There is a possibility that the area pulled out from the housing may be pulled by the operator. In this connector, when the force associated with the tension generated during the manufacturing process acts between the conductor connection part of the terminal fitting and the peripheral edge of the through hole in the conductive member, the magnitude and direction of the force may cause the terminal to There is a possibility that the quality of metal fittings and conductive members will be deteriorated. Therefore, in conventional connectors, the locking protrusion provided on the housing is inserted into the locking hole provided in the conductive member, and the force caused by pulling is transferred between the locking protrusion and the peripheral edge of the locking hole in the conductive member. By receiving the force, the transmission of force between the conductor connecting portion of the terminal fitting and the peripheral edge of the through hole in the conductive member is suppressed. However, in the end, this connector receives a pulling force between the locking protrusion and the periphery of the locking hole in the conductive member, so depending on the magnitude and direction of that force, the casing or There is a possibility that the quality of the conductive member may be deteriorated. Therefore, in this connector, it is desirable to be able to easily check whether there is any deterioration in quality during the manufacturing process.

そこで、本発明は、簡便な品質管理が可能なコネクタを提供することを、その目的とする。 Therefore, an object of the present invention is to provide a connector that allows easy quality control.

Apply a locking release force toward. In this holding structure 80, the locking release arm 82 is deflected by the locking release force, and in conjunction with the deflection of the locking release arm 82, the locking body 81 is displaced toward the fifth outer wall surface 21e. The lockable state between the locking body 81 and the other locking portion 521h is released.

カバー３０は、先に示したように第２壁体３２を第５外壁面２１ｅにおける第１外壁面２１ａ側に対して間隔を空けて対向配置させるので、その第２壁体３２によって、第５外壁面２１ｅの第１外壁面２１ａ側だけでなく、係止解除アーム８２の自由端（つまり、力点部８２ａ）についても覆っている。そこで、第２壁体３２には、可撓性を持たせた片持ちで、かつ、力点部８２ａを覆う押動部３２ａを設けている（図１から図３及び図７）。その押動部３２ａは、第１壁体３１側を固定端とし、第１開口３０ａ側を自由端とする片体状に形成されており、第５外壁面２１ｅ側に押し動かされることによって、接触状態にある力点部８２ａを第５外壁面２１ｅ側に押し動かして、係止体８１と相手方係止部５２１ｈとの間の係止可能な状態を解除させる。 As shown above, the cover 30 has the second wall 32 disposed facing the first outer wall surface 21a side of the fifth outer wall surface 21e with a space therebetween. It covers not only the first outer wall surface 21a side of the outer wall surface 21e but also the free end (that is, the force point portion 82a) of the lock release arm 82. Therefore, the second wall 32 is provided with a flexible pushing part 32a that is cantilevered and covers the force point part 82a (FIGS. 1 to 3 and 7). The pushing part 32a is formed in a piece shape with a fixed end on the first wall 31 side and a free end on the first opening 30a side, and when pushed toward the fifth outer wall surface 21e, The force point portion 82a in contact is pushed toward the fifth outer wall surface 21e to release the lockable state between the locking body 81 and the other locking portion 521h.

導電部品ＥＣは、組付け完了状態のハウジング２０及びカバー３０の成す内方の空間に収容され、かつ、端子引出口２０ｂから飛び出ている端子金具１０の導体接続部１２に対して導電体を電気接続させる収容領域ＥＣ１と、組付け完了状態のハウジング２０及びカバー３０の成す引出口３０ｃから外方に引き出させる引出領域ＥＣ２と、を有する（図２及び図４から図６）。ここで示す導電部品ＥＣは、矩形の収容領域ＥＣ１と矩形の引出領域ＥＣ２とに区分けされている。また、ここで示す導電部品ＥＣとは、先に示したように、導電部材４０と補強板５０の双方を備えるものである。この導電部品ＥＣにおいては、導電部材４０と補強板５０とによって収容領域ＥＣ１が構成され、導電部材４０のみによって引出領域ＥＣ２が構成される。 The conductive component EC is housed in the inner space formed by the housing 20 and the cover 30 in the assembled state, and connects the conductor to the conductor connection portion 12 of the terminal fitting 10 protruding from the terminal outlet 20b. It has a storage area EC1 to be connected, and a drawer area EC2 to be pulled out outward from the outlet 30c formed by the housing 20 and cover 30 in the assembled state (FIGS. 2 and 4 to 6). The conductive component EC shown here is divided into a rectangular accommodation area EC1 and a rectangular extraction area EC2. Moreover, the electrically conductive component EC shown here includes both the electrically conductive member 40 and the reinforcing plate 50, as shown above. In this electrically conductive component EC, the electrically conductive member 40 and the reinforcing plate 50 constitute an accommodation area EC1, and the electrically conductive member 40 alone constitutes a drawer area EC2.

導電部材４０は、複数の導電体を備えており、そのそれぞれの導電体によって回路パターンが形成されている。ここで示す導電部材４０は、フレキシブルプリント回路基板（所謂ＦＰＣ）であり、矩形に形成されている。 The conductive member 40 includes a plurality of conductors, each of which forms a circuit pattern. The conductive member 40 shown here is a flexible printed circuit board (so-called FPC), and is formed in a rectangular shape.

導電部材４０は、組付け完了状態のハウジング２０及びカバー３０の成す内方の空間に収容され、かつ、端子引出口２０ｂから飛び出ている端子金具１０の導体接続部１２に対して導電体を電気接続させる導体接続領域４０ａと、組付け完了状態のハウジング２０及びカバー３０の成す引出口３０ｃから外方に引き出させる導体引出領域４０ｂと、を有する（図２及び図４から図６）。ここで示す導電部材４０は、矩形の導体接続領域４０ａと矩形の導体引出領域４０ｂとに区分けされている。ここで示す導電部品ＥＣにおいては、積層状態の導電部材４０の導体接続領域４０ａと補強板５０の後述する補強板本体５１とによって収容領域ＥＣ１が構成され、導電部材４０の導体引出領域４０ｂによって引出領域ＥＣ２が構成される。 The conductive member 40 is housed in the inner space formed by the housing 20 and cover 30 in the assembled state, and connects the conductor to the conductor connection portion 12 of the terminal fitting 10 protruding from the terminal outlet 20b. It has a conductor connection area 40a to be connected, and a conductor pullout area 40b to be pulled out from the outlet 30c formed by the housing 20 and cover 30 in an assembled state (FIGS. 2 and 4 to 6). The conductive member 40 shown here is divided into a rectangular conductor connection area 40a and a rectangular conductor extraction area 40b. In the conductive component EC shown here, the conductor connection region 40a of the conductive member 40 in a laminated state and the reinforcing plate main body 51 (described later) of the reinforcing plate 50 constitute an accommodation region EC1, and the conductor lead-out region 40b of the conductive member 40 constitutes a storage region EC1. Area EC2 is configured.

導体接続領域４０ａは、導体接続部１２を挿通させる貫通孔であり、その貫通孔の内周面における導電体の電気接続部を導体接続部１２に電気接続させるスルーホール４１を有している（図４から図６）。ここで示す導体接続領域４０ａには、全ての端子金具１０の導体接続部１２を電気接続させるので、その端子金具１０毎に円形のスルーホール４１が形成されている。 The conductor connection region 40a is a through hole through which the conductor connection portion 12 is inserted, and has a through hole 41 through which the electrical connection portion of the conductor on the inner peripheral surface of the through hole is electrically connected to the conductor connection portion 12 ( Figures 4 to 6). In the conductor connection region 40a shown here, since the conductor connection portions 12 of all the terminal fittings 10 are electrically connected, a circular through hole 41 is formed for each terminal fitting 10.

補強板５０は、合成樹脂等の絶縁性材料で成形される。ここで示す補強板５０は、導体接続領域４０ａと同じ外郭形状（つまり、導体接続領域４０ａと同形状の矩形）で平板状に形成された補強板本体５１を有している（図４から図６）。導電部品ＥＣの収容領域ＥＣ１は、その補強板本体５１を導電部材４０の導体接続領域４０ａに積層状態で一体化させることによって構成される。この収容領域ＥＣ１においては、その導体接続領域４０ａと補強板本体５１とを接着剤等で貼り付けることによって、この導体接続領域４０ａと補強板本体５１とが積層状態で一体化される。 The reinforcing plate 50 is molded from an insulating material such as synthetic resin. The reinforcing plate 50 shown here has a reinforcing plate main body 51 formed in a flat plate shape with the same outline shape as the conductor connecting area 40a (that is, a rectangular shape having the same shape as the conductor connecting area 40a) (FIGS. 4 to 4). 6). The accommodation area EC1 of the conductive component EC is configured by integrating the reinforcing plate main body 51 with the conductor connection area 40a of the conductive member 40 in a laminated state. In the accommodation area EC1, the conductor connection area 40a and the reinforcing plate main body 51 are pasted together with an adhesive or the like, so that the conductor connection area 40a and the reinforcing plate main body 51 are integrated in a laminated state.

補強板本体５１は、ハウジング本体２１の端子引出領域２０ｃと導電部材４０の導体接続領域４０ａとの間に介在させる。よって、この補強板本体５１には、スルーホール４１と同心の貫通孔（以下、「端子挿通孔」という。）５１ａがスルーホール４１毎に形成されている（図４から図６）。ここで示す端子挿通孔５１ａは、スルーホール４１と同形状に形成されている。 The reinforcing plate main body 51 is interposed between the terminal extraction region 20c of the housing main body 21 and the conductor connection region 40a of the conductive member 40. Therefore, in this reinforcing plate main body 51, a through hole (hereinafter referred to as a "terminal insertion hole") 51a concentric with the through hole 41 is formed for each through hole 41 (FIGS. 4 to 6). The terminal insertion hole 51a shown here is formed in the same shape as the through hole 41.

例えば、ここで示す導電部品ＥＣの収容領域ＥＣ１においては、収容室２０ａに収容されている全ての端子金具１０の導体接続部１２をスルーホール４１と端子挿通孔５１ａに挿通させることによって、補強板本体５１がハウジング本体２１の端子引出領域２０ｃに載せ置かれる。このコネクタ１においては、その端子金具１０とハウジング２０と導電部品ＥＣ（導電部材４０、補強板５０）の設置状態で、対になる導体接続部１２とスルーホール４１の組み合わせ毎に半田付けを行って、その導体接続部１２とスルーホール４１を固着させる。このコネクタ１においては、その後、カバー３０が組み付けられる。 For example, in the storage area EC1 for the conductive components EC shown here, the reinforcing plate The main body 51 is placed on the terminal extraction area 20c of the housing main body 21. In this connector 1, with the terminal fitting 10, housing 20, and conductive parts EC (conductive member 40, reinforcing plate 50) installed, soldering is performed for each pair of conductor connection portions 12 and through holes 41. Then, the conductor connection portion 12 and the through hole 41 are fixed. In this connector 1, the cover 30 is then assembled.

ところで、このコネクタ１においては、スルーホール４１と端子挿通孔５１ａに導体接続部１２を挿し入れながら、端子金具１０とハウジング２０に対する導電部品ＥＣの設置作業を行っているときに、又は、その設置作業を終えて、導体接続部１２とスルーホール４１との接続作業が可能な状態になっているときに、その導電部品ＥＣの引出領域ＥＣ２（導体引出領域４０ｂ）が引出口３０ｃからの引出方向へと作業者に引っ張られてしまう可能性がある。そこで、このコネクタ１においては、その引っ張りに伴う力をハウジング２０と導電部品ＥＣとの間で受けさせることによって、端子金具１０の導体接続部１２と導電部品ＥＣにおけるスルーホール４１及び端子挿通孔５１ａのそれぞれの周縁部との間への力の伝達を抑える。この例示では、その引っ張りに伴う力をハウジング２０と補強板５０との間で受けさせる。 By the way, in this connector 1, when installing the conductive component EC to the terminal fitting 10 and the housing 20 while inserting the conductor connection part 12 into the through hole 41 and the terminal insertion hole 51a, When the work is finished and the connection work between the conductor connecting portion 12 and the through hole 41 is ready, the pull-out area EC2 (conductor pull-out area 40b) of the conductive component EC is in the pull-out direction from the pull-out opening 30c. There is a possibility that the worker will pull you away. Therefore, in this connector 1, the force accompanying the tension is received between the housing 20 and the conductive component EC, so that the through hole 41 and the terminal insertion hole 51a in the conductor connection portion 12 of the terminal fitting 10 and the conductive component EC are Suppresses the transmission of force between the respective peripheral parts of the In this example, the force associated with the tension is received between the housing 20 and the reinforcing plate 50.

具体的に、ハウジング２０は、導体接続部１２の端子引出口２０ｂからの突出方向（以下、「端子突出方向」という。）と引出領域ＥＣ２（導体引出領域４０ｂ）の引出口３０ｃからの引出方向（以下、「導体引出方向」という。）とに対する直交方向（以下、「幅方向」という。）で端子引出領域２０ｃを間にして１つずつ設け、その端子突出方向を軸方向とする円柱状又は円筒状の係止突起２４を有している（図２、図４及び図５）。そして、収容領域ＥＣ１における幅方向のそれぞれの側端部９０ａ，９０ｂは、係止突起２４を挿通させる係止突起２４毎の貫通孔であり、導体引出方向側とは逆側が半円状の半円孔部９１ａとして形成され、その半円孔部９１ａの弧状壁面を係止突起２４に係止可能な係止孔９１を有している（図４）。更に、スルーホール４１は、導体接続部１２に対する電気接続前（つまり、半田付け前）で、かつ、係止突起２４と半円孔部９１ａの弧状壁面とが係止状態のときに、自身の内周面における導体引出方向側とは逆側と導体接続部１２との間に隙間が設けられるように形成されている。そして、端子挿通孔５１ａは、導体接続部１２とスルーホール４１の電気接続前（つまり、半田付け前）で、かつ、係止突起２４と半円孔部９１ａの弧状壁面とが係止状態のときに、自身の内周面における導体引出方向側とは逆側と導体接続部１２との間に隙間が設けられるように形成されている。これにより、このコネクタ１においては、導電部品ＥＣの引出領域ＥＣ２が引出方向へと作業者に引っ張られたとしても、その引っ張りに伴う力を端子金具１０に伝えることなく、係止突起２４と収容領域ＥＣ１における係止孔９１の半円孔部９１ａの周縁部とで受けることができる。よって、このコネクタ１においては、端子金具１０や導電部品ＥＣの品質の低下を抑えることができる。 Specifically, the housing 20 has two directions: the direction in which the conductor connection portion 12 projects from the terminal outlet 20b (hereinafter referred to as the "terminal protrusion direction"), and the direction in which the conductor connection section 12 (hereinafter referred to as the "terminal protrusion direction") extends from the outlet 30c. (hereinafter referred to as the "conductor extraction direction"), one terminal extraction area 20c is provided in between in the direction perpendicular to the conductor extraction direction (hereinafter referred to as the "conductor extraction direction"). Alternatively, it has a cylindrical locking protrusion 24 (FIGS. 2, 4, and 5). Each of the side ends 90a and 90b in the width direction of the accommodation area EC1 is a through hole for each locking projection 24 through which the locking projection 24 is inserted, and the side opposite to the conductor pull-out direction side has a semicircular shape. It has a locking hole 91 that is formed as a circular hole portion 91a and can lock the arcuate wall surface of the semicircular hole portion 91a to the locking protrusion 24 (FIG. 4). Furthermore, the through-hole 41 has its own structure before electrical connection to the conductor connection portion 12 (that is, before soldering) and when the locking protrusion 24 and the arcuate wall surface of the semicircular hole portion 91a are locked. A gap is provided between the conductor connecting portion 12 and the inner circumferential surface on the side opposite to the direction in which the conductor is pulled out. The terminal insertion hole 51a is inserted into the terminal insertion hole 51a before the electrical connection between the conductor connection portion 12 and the through hole 41 (that is, before soldering), and when the locking protrusion 24 and the arcuate wall surface of the semicircular hole portion 91a are in a locked state. Sometimes, a gap is provided between the conductor connecting portion 12 and the inner circumferential surface of the conductor connecting portion 12 on the side opposite to the direction in which the conductor is pulled out. As a result, in this connector 1, even if the pull-out area EC2 of the conductive component EC is pulled in the pull-out direction by an operator, the force associated with the pull is not transmitted to the terminal fitting 10, and the locking protrusion 24 is accommodated. It can be received by the peripheral edge of the semicircular hole portion 91a of the locking hole 91 in the region EC1. Therefore, in this connector 1, deterioration in the quality of the terminal fittings 10 and the conductive components EC can be suppressed.

ここで示す２つの係止孔９１は、積層状態の導体接続領域４０ａと補強板本体５１とに形成される。この２つの係止孔９１は、その内の一方を円形の貫通孔とし、その内の他方を導体引出方向が長手方向になる長円形の長孔とする（図４）。円形の係止孔９１は、導体接続部１２とスルーホール４１の位置合わせを行う際の位置決め用の貫通孔としても利用する。一方、長孔としての係止孔９１は、孔間や各部品間の公差ばらつきを吸収させるためにも利用する。 The two locking holes 91 shown here are formed in the conductor connection region 40a and the reinforcing plate main body 51 in a laminated state. One of the two locking holes 91 is a circular through hole, and the other is an oblong hole whose longitudinal direction is the direction in which the conductor is drawn out (FIG. 4). The circular locking hole 91 is also used as a through hole for positioning when aligning the conductor connecting portion 12 and the through hole 41. On the other hand, the locking hole 91, which is a long hole, is also used to absorb tolerance variations between holes and between parts.

ここで、本実施形態の導電部品ＥＣは、それぞれの側端部９０ａ，９０ｂ毎に、その側端部９０ａ，９０ｂの側端面９０ａ_１，９０ｂ_１に沿う折り曲げ線で端子突出方向側又は端子突出方向側とは逆側に折り曲げられた折り曲げ片９２を有している（図４から図６）。その折り曲げ片９２の折り曲げ部９２ａは、導体引出方向側の第１端部９２ａ_１と、導体引出方向側とは逆側の第２端部９２ａ_２と、を有している（図４）。その第１端部９２ａ_１は、側端面９０ａ_１，９０ｂ_１上で半円孔部９１ａとの距離が最短になる最短位置Ｐｓよりも導体引出方向側に配置される。そして、第２端部９２ａ_２は、その最短位置Ｐｓよりも導体引出方向側とは逆側に配置される。 Here, the conductive component EC of the present embodiment has a terminal protruding direction or a terminal protruding side at a bending line along the side end surfaces 90a ₁ , 90b ₁ of each side end 90a, 90b. It has a bent piece 92 that is bent on the opposite side to the direction side (FIGS. 4 to 6). The bent portion 92a of the bent piece 92 has a first end 92a ₁ on the side in the conductor extraction direction and a second end 92a ₂ on the opposite side to the conductor extraction direction (FIG. 4). The first end portion 92a ₁ is disposed on the side end surfaces 90a ₁ and 90b ₁ on the conductor extraction direction side from the shortest position Ps where the distance to the semicircular hole portion 91a is the shortest. The second end portion _92a2 is disposed on the opposite side of the shortest position Ps to the conductor extraction direction.

具体的に、この例示では、折り曲げ片９２を補強板５０に設けている。この例示の補強板５０は、補強板本体５１における幅方向のそれぞれの側端部の側端面５１ｂに設けた折り曲げ片５２を有している（図４から図６）。導電部品ＥＣのそれぞれの側端部９０ａ，９０ｂの側端面９０ａ_１，９０ｂ_１には、補強板本体５１のそれぞれの側端部の側端面５１ｂが含まれている。従って、この例示の補強板５０は、換言するならば、収容領域ＥＣ１のそれぞれの側端部９０ａ，９０ｂにおける補強板本体５１の側端面５１ｂに設けた折り曲げ片５２を有している。それぞれの折り曲げ片５２は、その側端面５１ｂに沿う折り曲げ線で端子突出方向側又は端子突出方向側とは逆側に折り曲げられる。この補強板５０においては、そのそれぞれの折り曲げ片５２を導電部品ＥＣの折り曲げ片９２として利用する。よって、この補強板５０における折り曲げ片５２の折り曲げ部５２ａ（折り曲げ部９２ａ）は、補強板本体５１の側端面５１ｂ上の最短位置Ｐｓよりも導体引出方向側に第１端部９２ａ_１を有し、その側端面５１ｂ上の最短位置Ｐｓよりも導体引出方向側とは逆側に第２端部９２ａ_２を有している。ここで示す折り曲げ片５２（折り曲げ片９２）は、端子突出方向側に折り曲げられている。そして、ここで示す折り曲げ片５２における折り曲げ部５２ａ（折り曲げ片９２の折り曲げ部９２ａ）の第２端部９２ａ_２は、収容領域ＥＣ１における導体引出方向側とは逆側の端部に配置されている。 Specifically, in this example, a bent piece 92 is provided on the reinforcing plate 50. The reinforcing plate 50 in this example has bent pieces 52 provided on the side end surfaces 51b of each side end in the width direction of the reinforcing plate main body 51 (FIGS. 4 to 6). The side end surfaces 90a ₁ and 90b ₁ of the respective side ends 90a and 90b of the conductive component EC include the side end surfaces 51b of the respective side ends of the reinforcing plate main body 51. Therefore, in other words, this exemplary reinforcing plate 50 has bent pieces 52 provided on the side end surfaces 51b of the reinforcing plate main body 51 at the respective side end portions 90a, 90b of the accommodation area EC1. Each bent piece 52 is bent along a bending line along the side end surface 51b toward the terminal protrusion direction or the opposite side to the terminal protrusion direction. In this reinforcing plate 50, each bent piece 52 is used as a bent piece 92 of the conductive component EC. Therefore, the bent portion 52a (bent portion 92a) of the bent piece 52 in the reinforcing plate 50 has a first end _92a1 on the conductor extraction direction side from the shortest position Ps on the side end surface 51b of the reinforcing plate main body 51. , has a second end portion _92a2 on the side opposite to the conductor extraction direction from the shortest position Ps on the side end surface 51b. The bent piece 52 (bent piece 92) shown here is bent in the terminal protrusion direction. The second end 92a2 of the bent portion 52a of the bent piece 52 shown here (the bent portion 92a of the bent piece ₉₂ ) is located at the end of the storage area EC1 on the opposite side to the conductor pull-out direction. .

このような構成により、本実施形態のコネクタ１においては、製造工程での引っ張りに伴う力が基準引張力以上になったときに、半円孔部９１ａから折り曲げ部９２ａに向けて導電部品ＥＣの収容領域ＥＣ１（導体接続領域４０ａと補強板本体５１）に亀裂が入り、その亀裂が折り曲げ部９２ａにおける折り曲げ線に沿って広がっていく。収容領域ＥＣ１においては、半円孔部９１ａから折り曲げ部９２ａにおける最短位置Ｐｓ又は当該最短位置Ｐｓよりも導体引出方向側とは逆側に向けて亀裂が生じる。つまり、導電部品ＥＣ（導電部材４０と補強板５０）は、引出領域ＥＣ２（導体引出領域４０ｂ）に対して導体引出方向に基準引張力より小さい力が加えられて、係止突起２４と半円孔部９１ａの弧状壁面とが係止状態になったときに、その係止状態を維持させる一方、引出領域ＥＣ２に対して導体引出方向に基準引張力以上の力が加えられて、係止突起２４と半円孔部９１ａの弧状壁面とが係止状態になったときに、その半円孔部９１ａから折り曲げ部９２ａにおける最短位置Ｐｓ又は当該最短位置Ｐｓよりも導体引出方向側とは逆側に向けて亀裂を生じさせ、かつ、その亀裂を折り曲げ部９２ａにおける折り曲げ線に沿って引出領域ＥＣ２における導体引出方向側とは逆側の端部に向けて延伸させるものとして形成されている。 With such a configuration, in the connector 1 of the present embodiment, when the force associated with pulling in the manufacturing process exceeds the reference tensile force, the conductive component EC is moved from the semicircular hole portion 91a toward the bent portion 92a. A crack appears in the accommodation area EC1 (the conductor connection area 40a and the reinforcing plate main body 51), and the crack spreads along the bending line at the bending portion 92a. In the accommodation area EC1, cracks occur from the semicircular hole 91a to the shortest position Ps in the bent part 92a or to the side opposite to the conductor extraction direction from the shortest position Ps. In other words, the conductive component EC (the conductive member 40 and the reinforcing plate 50) is connected to the locking protrusion 24 in a semicircular shape when a force smaller than the standard tensile force is applied to the pull-out area EC2 (conductor pull-out area 40b) in the conductor pull-out direction. When the arcuate wall surface of the hole 91a is in a locked state, the locked state is maintained, and a force equal to or higher than the reference tensile force is applied to the pull-out area EC2 in the conductor pull-out direction, causing the locking protrusion to 24 and the arcuate wall surface of the semicircular hole portion 91a are in a locked state, the shortest position Ps from the semicircular hole portion 91a to the bent portion 92a, or the opposite side of the conductor pull-out direction from the shortest position Ps. It is formed so that a crack is generated toward the bending portion 92a, and the crack is extended toward the end of the pull-out area EC2 on the opposite side to the conductor pull-out direction side along the bend line in the folded portion 92a.

例えば、従来のコネクタのように導電部品に折り曲げ片９２が設けられていない場合、引出領域に対して導体引出方向に過大な力が加えられたときには、係止孔から当該係止孔との距離が最も短い導電部品の側端面の最短位置Ｐｓに向けて又は当該側端面における最短位置Ｐｓの周辺に向けて亀裂が入る。このため、従来のコネクタにおいては、その亀裂が短いので、そして、その亀裂の方向が定まらないので、その亀裂を製造工程で見つけることが難しい。しかしながら、本実施形態のコネクタ１においては、引出領域ＥＣ２での亀裂の長さが従来と同等の長さであったとしても、その亀裂を折り曲げ部９２ａの折り曲げ線に沿って延伸させることができる。このため、このコネクタ１においては、従来よりも亀裂が長く、かつ、その亀裂の方向が特定されているので、その亀裂を製造工程で容易に見つけることができる。従って、本実施形態のコネクタ１は、製造工程での簡便な品質管理が可能なものとなっている。 For example, in the case where the conductive component is not provided with the bending piece 92 like in a conventional connector, when an excessive force is applied to the lead-out area in the conductor pull-out direction, the distance from the locking hole to the locking hole A crack appears toward the shortest position Ps on the side end surface of the conductive component where is the shortest, or toward the periphery of the shortest position Ps on the side end surface. Therefore, in conventional connectors, it is difficult to detect the crack during the manufacturing process because the crack is short and the direction of the crack is uncertain. However, in the connector 1 of this embodiment, even if the length of the crack in the pull-out area EC2 is the same as that of the conventional one, the crack can be extended along the bending line of the bending portion 92a. . Therefore, in this connector 1, the crack is longer than in the conventional connector, and the direction of the crack is specified, so that the crack can be easily found during the manufacturing process. Therefore, the connector 1 of this embodiment allows easy quality control during the manufacturing process.

更に、本実施形態のコネクタ１においては、係止孔９１と収容領域ＥＣ１及び折り曲げ片９２（折り曲げ片５２）の成す外郭端面（補強板５０の周端面）との間の最短距離が従来よりも長くなっているので、従来よりも大きな引張力を引出領域ＥＣ２（導体引出領域４０ｂ）に掛けたとしても、その引張力が基準引張力に達するまで、収容領域ＥＣ１に亀裂が入り難くなっている。つまり、本実施形態のコネクタ１は、従来よりも導電部品ＥＣの強度を高めることができるので、この点からも導電部品ＥＣの品質の低下を抑えることができる。 Furthermore, in the connector 1 of this embodiment, the shortest distance between the locking hole 91 and the outer edge surface (peripheral end surface of the reinforcing plate 50) formed by the accommodation area EC1 and the bent piece 92 (the bent piece 52) is longer than that of the conventional one. Because it is longer, even if a larger tensile force than before is applied to the pull-out area EC2 (conductor pull-out area 40b), it is difficult for cracks to appear in the accommodation area EC1 until the tensile force reaches the standard tensile force. . In other words, the connector 1 of this embodiment can increase the strength of the conductive component EC compared to the conventional one, so that deterioration in the quality of the conductive component EC can also be suppressed from this point of view.

更に、本実施形態のコネクタ１においては、上述した折り曲げ片５２を有するものとして補強板５０を成形すればよいので、導電部材４０に汎用性を持たせることができ、また、導電部材４０に従来のものを流用することもできる。 Furthermore, in the connector 1 of this embodiment, the reinforcing plate 50 may be formed to have the above-mentioned bent piece 52, so the conductive member 40 can be made versatile, and the conductive member 40 can be You can also reuse the one.
