Description

本発明は、例えばコネクタに接続されている電線に装着される電線カバーに関する。 The present invention relates to an electric wire cover that is attached to, for example, an electric wire connected to a connector.

この種の電線カバーとして、例えば下記特許文献１に記載のものが知られている。これは、コネクタから引き出されている電線の曲げ部分に宛がわれる電線押さえ部を備え、その電線押さえ部を弾性係合片によってコネクタハウジングに固定した構造である。 As this type of wire cover, for example, the one described in Patent Document 1 below is known. This is a structure in which an electric wire holding portion addressed to a bent portion of an electric wire drawn out from the connector is provided, and the electric wire holding portion is fixed to the connector housing by an elastic engagement piece.

ところで、コネクタは周囲に他の部品が密集して配置されて空間的な余裕が少ない場所に配置されることもある。このような場合、コネクタハウジングは極力小型化されるから、コネクタハウジングに電線カバーのロック構造を設けることができず、電線カバーはコネクタではなく、コネクタが取り付けられている相手側部材に固定される構造を採用せざるを得ない。 By the way, the connector may be arranged in a place where other parts are densely arranged around the periphery and there is little space. In such a case, since the connector housing is miniaturized as much as possible, the connector housing cannot be provided with a wire cover lock structure, and the wire cover is not a connector but is fixed to the mating member to which the connector is attached. The structure must be adopted.

例えば、車両用ドアにあって、ドアハンドルの操作を検出するためのスイッチに装着されるコネクタでは、ドアの内部構造が複雑で密集した形態となっているため、上述のように電線カバーをコネクタではなく、そのコネクタが取り付けられるドア内の相手側部材に固定する構造とされる。
特開２００４−３４８９８８公報 For example, a connector mounted on a switch for detecting operation of a door handle in a vehicle door has a complicated and dense internal structure of the door. Instead, the structure is such that the connector is fixed to a mating member in the door to which the connector is attached.
JP 2004-348888 A

しかしながら、上述のように電線カバーをコネクタが取り付けられる相手側部材に固定するようにしたとしても、ドア内に十分なスペースがないため、電線カバーの弾性係合片の先端を相手側部材に向けて挿入するための進入路を確保することが精一杯であって、相手側部材に係合した弾性係合片の周囲に余裕スペースを確保することができない。このため、修理・点検等のためにコネクタ、ひいては電線カバーを取り外す必要が生じたときでも、弾性係合片の係合を解除するためのマイナスドライバ等の治具は、やはり弾性係合片の基端側から奥に向かって真っ直ぐに挿入するしかなく、弾性係合片の係合解除操作が非常に行いにくく、作業性が極めて悪いという問題があった。 However, even if the electric wire cover is fixed to the mating member to which the connector is attached as described above, there is not enough space in the door, so the tip of the elastic engagement piece of the electric wire cover faces the mating member. In this case, it is sufficient to secure an approach path for insertion, and it is not possible to secure a marginal space around the elastic engagement piece engaged with the counterpart member. For this reason, even when it is necessary to remove the connector and thus the wire cover for repair and inspection, a jig such as a flathead screwdriver for releasing the engagement of the elastic engagement piece is still There is no other way than to insert it straight from the base end to the back, and there is a problem that the disengagement operation of the elastic engagement piece is very difficult and the workability is extremely poor.

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、電線押さえ部の弾性係合片の基端側から係合解除用治具を差し込んで電線押さえ部を相手側部材から容易に取り外すことができるようにすることを目的とする。 The present invention has been completed based on the above-described circumstances, and the wire pressing portion can be easily removed from the mating member by inserting a disengaging jig from the base end side of the elastic engagement piece of the wire pressing portion. It is intended to be able to be removed.

上記の目的を達成するための手段として、請求項１の発明は、コネクタから引き出された電線をその引き出し方向とは異なる方向に曲げるための電線カバーであって、前記コネクタに固定されるコネクタ側固定部と、前記電線に宛がわれる電線押さえ部と、前記コネクタ側固定部と前記電線押さえ部とを連結する連結部とを備え、前記電線押さえ部には係合部を備えた弾性係合片が突設され、その係合部を前記コネクタを取り付けてある相手側部材に設けた被係合部と係合させることで前記電線押さえ部を前記相手側部材に固定可能とされており、前記弾性係合片の先端には前記弾性係合片の基端側から差し込まれた治具を引っ掛けて前記弾性係合片をその係合部と前記被係合部との係合を解除する方向に変位可能とする係合解除用の引掛け部が設けられている構成としたところに特徴を有する。 As means for achieving the above object, the invention of claim 1 is an electric wire cover for bending an electric wire drawn out from a connector in a direction different from the drawing direction, and is a connector side fixed to the connector. An elastic engagement provided with a fixing part, an electric wire pressing part addressed to the electric wire, a connecting part for connecting the connector side fixing part and the electric wire pressing part, and the electric wire pressing part having an engaging part A piece is protruded, and the wire holding portion can be fixed to the counterpart member by engaging the engaging portion with the engaged portion provided in the counterpart member to which the connector is attached. A jig inserted from the base end side of the elastic engagement piece is hooked on the distal end of the elastic engagement piece to release the engagement between the engagement portion and the engaged portion of the elastic engagement piece. Hook for disengagement that can be displaced in the direction Characterized in place where the structure is provided.

請求項２の発明は、請求項１に記載のものにおいて、前記相手側部材にはそれぞれ前記被係合部を備えた係合壁部が互いに対向状態で一対設けられると共に、前記弾性係合片は前記両係合壁部対に対して外側から嵌め込むように対をなして設けられ、かつ、前記各弾性係合片には前記各係合壁部対の内側に進入して前記弾性係合片との間で前記各係合壁部を挟み込む補助壁が一体に設けられているところに特徴を有する。 According to a second aspect of the present invention, in the one according to the first aspect, the mating member is provided with a pair of engaging wall portions each provided with the engaged portion, facing each other, and the elastic engaging piece. Are provided in pairs so as to be fitted to both the engagement wall pairs from the outside, and each elastic engagement piece enters the inside of each engagement wall portion pair to enter the elastic engagement. It is characterized in that an auxiliary wall that sandwiches each of the engaging wall portions with a piece is integrally provided.

請求項３の発明は、請求項２に記載のものにおいて、前記弾性係合片の係合部は係合孔として形成され、前記係合壁部の前記被係合部は係合突部として形成されているところに特徴を有する。 According to a third aspect of the present invention, the engaging portion of the elastic engaging piece is formed as an engaging hole, and the engaged portion of the engaging wall portion is an engaging protrusion. It is characterized by being formed.

＜請求項１の発明＞
請求項１の発明によると、治具を弾性係合片の基端側から挿入し、治具の先端を引掛け部に引っ掛けることができる。これにより、弾性係合片をその係合部と被係合部との係合を解除する方向に変位させて係合を解除することができる。したがって、弾性係合片の基端側から治具を挿入して、弾性係合片を相手側部材から取り外すことができる。 <Invention of Claim 1>
According to invention of Claim 1, a jig | tool can be inserted from the base end side of an elastic engagement piece, and the front-end | tip of a jig | tool can be hooked on a hook part. Thereby, the engagement can be released by displacing the elastic engagement piece in the direction of releasing the engagement between the engagement portion and the engaged portion. Therefore, the elastic engagement piece can be removed from the counterpart member by inserting a jig from the base end side of the elastic engagement piece.

＜請求項２の発明＞
請求項２の発明によると、係合壁部を弾性係合片と補助壁との間で挟み込むことができる。したがって、係合部と被係合部との係合状態を保持することができる。仮に、弾性係合片が外側に撓み変形しようとしても、弾性係合片が補助壁と別体に設けられている場合よりも弾性係合片が撓みにくくなるため、係合部と被係合部との係合が容易に解除されるおそれがない。 <Invention of Claim 2>
According to the invention of claim 2, the engagement wall portion can be sandwiched between the elastic engagement piece and the auxiliary wall. Therefore, the engaged state between the engaging portion and the engaged portion can be maintained. Even if the elastic engagement piece is bent outward and deformed, the elastic engagement piece is less likely to bend than when the elastic engagement piece is provided separately from the auxiliary wall. There is no possibility that the engagement with the part is easily released.

＜請求項３の発明＞
仮に、係合部を係合突部とし、被係合部を係合孔として形成した場合、係合突部と係合孔との係合力は、係合孔の深さ寸法、すなわち係合壁部の厚さによって決定される。ここで、係合力をさらに高めるためには、弾性係合片を薄くして、その分だけ係合壁部を厚くする必要がある。しかしながら、弾性係合片の厚さを薄くすると弾性力の低下を招き、弾性係合片に補助壁を一体に設けたことの意義が失われてしまう。その点、請求項３の発明によると、弾性係合片を係合壁部と反対側に肉盛りすることで係合孔の深さ寸法を稼ぐことができる。したがって、弾性係合片の弾性力を低下させることなく係合力を高めることができる。 <Invention of Claim 3>
If the engaging portion is an engaging protrusion and the engaged portion is an engaging hole, the engaging force between the engaging protrusion and the engaging hole is the depth dimension of the engaging hole, that is, the engagement It is determined by the thickness of the wall. Here, in order to further increase the engagement force, it is necessary to make the elastic engagement piece thinner and make the engagement wall portion thicker accordingly. However, if the thickness of the elastic engagement piece is reduced, the elastic force is lowered, and the significance of providing the auxiliary wall integrally with the elastic engagement piece is lost. In that respect, according to the invention of claim 3, the depth dimension of the engagement hole can be gained by building up the elastic engagement piece on the side opposite to the engagement wall portion. Therefore, the engagement force can be increased without reducing the elastic force of the elastic engagement piece.

＜実施形態＞
本発明の実施形態を図１ないし図６によって説明する。本発明における電線カバー１は、相手側部材４０に取り付けられているコネクタ（図示しない）の電線引き出し面から引き出された電線Ｗ（実際には複数の電線Ｗを束ねて構成された電線群であるものの、以下の説明においては、単に電線Ｗという。）をその引き出し方向とは異なる方向に曲げて、所定方向に導出するためのものである。図１は、電線カバー１を底面側から見た図であって、電線カバー１の底面側には図示しない電線Ｗが配されている。 <Embodiment>
An embodiment of the present invention will be described with reference to FIGS. The electric wire cover 1 in the present invention is an electric wire W (actually an electric wire group configured by bundling a plurality of electric wires W) drawn from an electric wire drawing surface of a connector (not shown) attached to the counterpart member 40. However, in the following description, the electric wire W is simply bent in a direction different from the drawing direction and led out in a predetermined direction. FIG. 1 is a view of the electric wire cover 1 as seen from the bottom surface side, and an electric wire W (not shown) is arranged on the bottom surface side of the electric wire cover 1.

電線カバー１は、図１に示すように、コネクタに固定されるコネクタ側固定部１０と、相手側部材４０に固定される電線押さえ部２０と、コネクタ側固定部１０と電線押さえ部２０とを連結する連結部３０とを備えている。一方、相手側部材４０は、図６に示すように、対向状態で設けられた一対の係合壁部４１と、両係合壁部４１の端部において両係合突部４１が対向する対向面と反対側の面から突出する一対の係合突部（本発明における被係合部に相当する。）４２とを備えている。尚、以下の説明において、上下方向とは図１における紙面と直交する方向を基準として奥側を上方とし、前後方向とは図１における左右方向を基準として図示右側を前方とし、幅方向とは図１における上下方向を基準とする。 As shown in FIG. 1, the wire cover 1 includes a connector-side fixing portion 10 that is fixed to a connector, a wire pressing portion 20 that is fixed to a mating member 40, a connector-side fixing portion 10, and a wire pressing portion 20. And a connecting portion 30 to be connected. On the other hand, as shown in FIG. 6, the mating member 40 has a pair of engaging wall portions 41 provided in an opposed state, and opposed to both engaging projections 41 at the end portions of both engaging wall portions 41. And a pair of engaging protrusions (corresponding to engaged parts in the present invention) 42 protruding from the surface opposite to the surface. In the following description, the up and down direction is the upper side with respect to the direction orthogonal to the paper surface in FIG. 1, the front and rear direction is the front with the right side in the drawing as the reference in the left and right direction in FIG. The vertical direction in FIG.

コネクタ側固定部１０は、幅方向に対向状態で配される一対の側板１１を有し、これらの上端同士を上端壁１２で連結した構成である。各側板１１の外側面には、後方に突出する固定板１３が一体に形成されており、固定板１３には、その下端縁から上方に向けて切り込まれた固定溝１４が設けられている。固定溝１４は、コネクタに設けられたロック突部（図示しない）と係合することで、コネクタ側固定部１０をコネクタに固定することが可能である。 The connector side fixing portion 10 has a pair of side plates 11 arranged in an opposing state in the width direction, and has a configuration in which these upper ends are connected by an upper end wall 12. A fixing plate 13 protruding rearward is integrally formed on the outer surface of each side plate 11, and the fixing plate 13 is provided with a fixing groove 14 cut upward from the lower edge of the fixing plate 13. . The fixing groove 14 can fix the connector side fixing portion 10 to the connector by engaging with a locking protrusion (not shown) provided in the connector.

連結部３０は、図２に示すように、上端壁１２の前端縁から前方に延びる形態で可撓性を有する撓み部３１と、撓み部３１の前端縁部に連結された電線拘束部３２とから構成されている。撓み部３１の幅寸法は、ハウジング側固定部１０の両側板１１間の距離よりやや小さめに設定されている。撓み部３１は、相手側部材４０側に曲げられると両側板１１の間に配されると共に、両側板１１の内側面と撓み部３１の内面とからなる曲げ収容部が形成されるようになっている。 As shown in FIG. 2, the connecting portion 30 includes a flexible bending portion 31 that extends forward from the front end edge of the upper end wall 12, and a wire restraining portion 32 that is connected to the front end edge portion of the bending portion 31. It is composed of The width dimension of the bending part 31 is set to be slightly smaller than the distance between the both side plates 11 of the housing side fixing part 10. When the bending portion 31 is bent toward the mating member 40 side, the bending portion 31 is arranged between the both side plates 11, and a bending housing portion including the inner side surface of the both side plates 11 and the inner surface of the bending portion 31 is formed. ing.

電線拘束部３２は柱状をなし、撓み不能に形成されている。この電線拘束部３２は、結束バンド（図示しない）によって電線Ｗと共に巻きつけられる。そのため、電線押さえ部２０が撓み部３１を撓ませて相手側部材４０（図１における紙面手前側）に向けて曲げられると、電線Ｗの曲げ部分が、前記した曲げ収容部の内部に収容される。 The electric wire restraint portion 32 has a column shape and is formed so as not to bend. This electric wire restraint part 32 is wound with the electric wire W by a binding band (not shown). Therefore, when the wire holding portion 20 bends the bending portion 31 and bends toward the mating member 40 (the front side in FIG. 1), the bent portion of the electric wire W is accommodated inside the bending accommodating portion. The

電線押さえ部２０は、その後端縁部が電線拘束部３２に連結された略長方形状をなす基板部２１と、その両側縁から前後両側に分かれて下方に突設された４つの側壁とを備えている。これらの側壁のうち、前側の両側壁は一対の案内突部２２とされ、後側の両側壁は一対の弾性係合片２３とされている。
両案内突部２２は、基板部２１の前端側両側縁から対向状態で下方に突出している。案内突部２２の突出高さは、電線Ｗの径寸法とほぼ同じかやや大きめとなるように設定されている。基板部２１の下面は、電線Ｗが曲げられた状態にあるときには、電線Ｗの弾発力により電線Ｗに宛がわれることになるため、両案内突部２２の間に電線Ｗを配置することで、電線Ｗを確実に基板部２１の前端から前方に導出させることができるようになっている。 The wire pressing portion 20 includes a substrate portion 21 having a substantially rectangular shape whose rear end edge portion is connected to the wire restraining portion 32, and four side walls that protrude from the both side edges to the front and rear sides and project downward. ing. Among these side walls, the front side walls are a pair of guide protrusions 22, and the rear side walls are a pair of elastic engagement pieces 23.
Both guide protrusions 22 protrude downward from the front end side both side edges of the substrate part 21 in an opposed state. The protrusion height of the guide protrusion 22 is set to be substantially the same as or slightly larger than the diameter dimension of the electric wire W. When the electric wire W is in a bent state, the lower surface of the substrate portion 21 is addressed to the electric wire W by the elastic force of the electric wire W. Therefore, the electric wire W is disposed between the guide protrusions 22. Thus, the electric wire W can be reliably led out from the front end of the substrate portion 21.

両弾性係合片２３は、基板部２１の後端側両側縁から対向状態で下方に延出された撓み規制部２３Ａと、撓み規制部２３Ａの下端部外側面から対向状態で下方に向けて片持ち状に突出した撓み許容部２３Ｂとから構成されている。撓み許容部２３Ｂは、対をなして係合突部４２を挟むように突出する一対の支持腕２３Ｂ１と、両支持腕２３Ｂ１の先端間を一体に連結して架設された架設部２３Ｂ２とからなり、全体としてコ字型をなしている。架設部２３Ｂ２の上面は、撓み規制部２３Ａの下面より下方に突出した位置に設定されており、両支持腕２３Ｂ１の両内側面と架設部２３Ｂ２の上面と撓み規制部２３Ａの下面とから構成される係合孔（本発明における係合部に相当する。）２５が形成されている。係合孔２５は、係合突部４２と係合させることで、電線押さえ部２０を相手側部材４０に固定することが可能である。 Both elastic engagement pieces 23 are directed downward from both side edges of the rear end side of the base plate portion 21 in a facing state, and downward from the outer surface of the lower end of the bending control portion 23A. It is comprised from the bending | flexion permission part 23B which protruded in the cantilever shape. The bending allowance portion 23B includes a pair of support arms 23B1 that project in a pair so as to sandwich the engagement protrusion 42, and a construction portion 23B2 that is constructed by integrally connecting the tips of both support arms 23B1. As a whole, it is U-shaped. The upper surface of the erection part 23B2 is set at a position protruding downward from the lower surface of the deflection restricting part 23A, and is composed of both inner side surfaces of both support arms 23B1, the upper surface of the erection part 23B2, and the lower surface of the deflection restricting part 23A. An engagement hole (corresponding to an engagement portion in the present invention) 25 is formed. The engagement hole 25 can be engaged with the engagement protrusion 42 to fix the wire pressing portion 20 to the counterpart member 40.

電線押さえ部２０が相手側部材４０に固定されると、基板部２１の下面が曲げ状態にある電線Ｗから上方に向かう弾発力を受けて係合突部４２の下面と架設部２３Ｂ２の上面とが当たり合った状態となる。この状態では、側板２２の下面と係合壁部４１の上面との間に間隔Ｓが生じるように設計されている。この間隔Ｓを設けた理由は、架設部２３Ｂ２の上面がその基端側を中心として揺動軌跡を描きながら変位し、架設部２３Ｂ２が係合突部４２を乗り越える際にその変位前より上方位置を通過するためである。したがって、間隔Ｓは、側板２２の下面と係合壁部４１の上面とを接触させた状態において、架設部２３Ｂ２が係止突部４２を乗り越えることができるような長さに設定されている。 When the wire holding portion 20 is fixed to the mating member 40, the lower surface of the substrate portion 21 receives an upward elastic force from the electric wire W in the bent state, and the lower surface of the engaging protrusion 42 and the upper surface of the installation portion 23B2. And hit the state. In this state, the distance S is designed to be generated between the lower surface of the side plate 22 and the upper surface of the engagement wall portion 41. The reason for providing this distance S is that the upper surface of the erection part 23B2 is displaced while drawing a swinging locus around the base end side, and when the erection part 23B2 gets over the engagement protrusion 42, it is positioned higher than before the displacement. Is to pass through. Therefore, the interval S is set to such a length that the erected portion 23B2 can get over the locking projection 42 in a state where the lower surface of the side plate 22 and the upper surface of the engaging wall portion 41 are in contact with each other.

両弾性係合片２３の内側には、基板部２１から対向状態で下方に突出する一対の補助壁２４が形成されている。補助壁２４は、弾性係合片２３と対向状態で配される対向壁２４Ａと、対向壁２４Ａの前後両側縁から幅方向外側に延出して対向壁２４Ａの撓み変形を規制する規制壁２４Ｂとからなり、全体として断面コ字型の柱状をなしている。補助壁２４の下端は、撓み許容部２３Ｂの下端とほぼ揃う高さ位置に設定されている。また、規制壁２４Ｂの幅方向外側縁は撓み規制部２３Ａと一体に連結されている。これにより、撓み規制部２３Ａが撓み変形することを規制し、撓み許容部２３Ｂのみを幅方向に撓ませることが可能である。さらに、撓み許容部２３Ｂの弾性力は、撓み規制部２３Ａが補助壁２４と別体に形成されている場合よりも大きくなり、係合孔２５と係合突部４２との係合力を高めることができる。尚、撓み許容部２３Ｂの内面と規制壁２４Ｂの側端との間の距離は、係合壁部４１の厚さ寸法とほぼ同じかこれよりやや大きめに設定されている。 A pair of auxiliary walls 24 projecting downward from the substrate portion 21 in a facing state are formed inside the elastic engagement pieces 23. The auxiliary wall 24 includes a facing wall 24A arranged in a state of facing the elastic engagement piece 23, and a regulating wall 24B that extends outward in the width direction from both front and rear side edges of the facing wall 24A and regulates the bending deformation of the facing wall 24A. As a whole, it has a columnar shape with a U-shaped cross section. The lower end of the auxiliary wall 24 is set to a height position that is substantially aligned with the lower end of the bending allowance portion 23B. Further, the outer edge in the width direction of the regulating wall 24B is integrally connected to the deflection regulating portion 23A. Thereby, it is possible to restrict the bending restricting portion 23A from being bent and to bend only the bending allowing portion 23B in the width direction. Furthermore, the elastic force of the bending allowance portion 23B becomes larger than when the bending restriction portion 23A is formed separately from the auxiliary wall 24, and the engagement force between the engagement hole 25 and the engagement protrusion 42 is increased. Can do. The distance between the inner surface of the bending allowance portion 23B and the side end of the regulating wall 24B is set to be approximately the same as or slightly larger than the thickness dimension of the engagement wall portion 41.

撓み許容部２３Ｂの架設部２３Ｂ２の外側面には、幅方向外側に張り出した張り出し部２７が形成され、この張り出し部２７には、上下方向（撓み許容部２３Ｂの突出方向）に貫通する引掛け孔（本発明における引掛け部に相当する。）２６が形成されている。引掛け孔２６は、弾性係合片２３の基端側から臨んだ位置に配されており、基端部２１側からマイナスドライバ（本発明における治具に相当する。）５０の先端が挿入可能な大きさに設定されている。したがって、弾性係合片２３の基端側からマイナスドライバ５０を差し込んで引掛け孔２６に引っ掛けて、撓み許容部２３Ｂを幅方向外側（係合孔２５と係合突部４２との係合を解除する方向）に変位させることができる。尚、引掛け孔２６を弾性係合片２３の基端側から臨んだ位置に配した理由は、仮に引掛け孔２６が弾性係合片２３の基端側から見えない位置に配されている場合には、マイナスドライバ５０を弾性係合片２３の基端側から挿入したとしても、マイナスドライバ５０の先端を引掛け孔２６に差し込むことが困難になるためである。 A protruding portion 27 protruding outward in the width direction is formed on the outer surface of the erection portion 23B2 of the bending allowance portion 23B, and the protruding portion 27 is hooked through in the vertical direction (the protruding direction of the bending allowance portion 23B). A hole 26 (corresponding to the hooking portion in the present invention) 26 is formed. The hook hole 26 is disposed at a position facing the base end side of the elastic engagement piece 23, and the tip of a minus driver (corresponding to a jig in the present invention) 50 can be inserted from the base end portion 21 side. Is set to a large size. Accordingly, the minus driver 50 is inserted from the base end side of the elastic engagement piece 23 and hooked on the hook hole 26, and the bending allowance portion 23 </ b> B is engaged in the width direction outer side (the engagement hole 25 and the engagement protrusion 42 are engaged with each other). In the direction of release). The reason why the hook hole 26 is disposed at a position facing the base end side of the elastic engagement piece 23 is that the hook hole 26 is disposed at a position where the hook hole 26 cannot be seen from the base end side of the elastic engagement piece 23. In this case, even if the minus driver 50 is inserted from the base end side of the elastic engagement piece 23, it is difficult to insert the tip of the minus driver 50 into the hooking hole 26.

本実施形態は以上のような構造であって続いてその作用を説明する。
まず、電線押さえ部２０の相手側部材４０への取り付けについて説明する。電線押さえ部２０を係合突部４２に向けて押し込むと、撓み部３１が撓むと共に電線Ｗが曲げられ、電線Ｗの弾発力によって基板部２１の下面に電線Ｗが宛がわれる。電線Ｗを両案内突部２２の間に配して、さらに電線押さえ部２０を押し込むと、係合壁部４１が撓み許容部２３Ｂと補助壁２４との間に進入し、撓み許容部２３Ｂの先端が係合突部４２に乗り上げて撓み許容部２３Ｂを幅方向外側へ撓ませつつ、撓み許容部２３Ｂの先端が係合突部４２を乗り越えると撓み許容部２３Ｂが復帰し、係合孔２５と係合突部４２とが係合する。こうして、電線押さえ部２０が相手側部材４０に固定される。 The present embodiment has the structure as described above, and its operation will be described subsequently.
First, the attachment of the wire holding part 20 to the mating member 40 will be described. When the electric wire pressing portion 20 is pushed toward the engaging protrusion 42, the bending portion 31 is bent and the electric wire W is bent, and the electric wire W is applied to the lower surface of the substrate portion 21 by the elastic force of the electric wire W. When the electric wire W is disposed between the guide protrusions 22 and the electric wire pressing portion 20 is further pushed in, the engaging wall portion 41 enters between the bending allowance portion 23B and the auxiliary wall 24, and the bending allowance portion 23B When the tip of the bending allowance 23B climbs over the engagement protrusion 42 while the tip rides on the engagement protrusion 42 and bends the bending allowance 23B outward in the width direction, the bending allowance 23B returns to the engagement hole 25. And the engaging protrusion 42 are engaged. In this way, the wire pressing portion 20 is fixed to the mating member 40.

次に、電線押さえ部２０の相手側部材４０からの取り外しについて説明する。マイナスドライバ５０の先端を一方の弾性係合片２３の基端側から挿入して引掛け孔２５に差し込む。そして、マイナスドライバ５０の先端を幅方向外側に変位させて、係合孔２５と係合突部４２との係合を解除する。続いて、マイナスドライバ５０の先端を他方の弾性係合片２３の基端側から挿入して引掛け孔２５に差し込み、マイナスドライバ５０の先端を幅方向外側に変位させて、係合孔２５と係合突部４２との係合を解除することで、電線押さえ部２０を相手側部材４０から取り外すことができる。 Next, the removal from the mating member 40 of the wire pressing part 20 will be described. The tip of the minus driver 50 is inserted from the base end side of one elastic engagement piece 23 and inserted into the hooking hole 25. Then, the tip of the minus driver 50 is displaced outward in the width direction, and the engagement between the engagement hole 25 and the engagement protrusion 42 is released. Subsequently, the tip of the minus driver 50 is inserted from the base end side of the other elastic engagement piece 23 and inserted into the hooking hole 25, and the tip of the minus driver 50 is displaced outward in the width direction. By releasing the engagement with the engagement protrusion 42, the wire pressing portion 20 can be removed from the counterpart member 40.

以上のように、本実施形態では以下に示す効果を奏することができる。
１．解除用の治具５０を弾性係合片２３の基端側から挿入し、マイナスドライバ５０の先端を引掛け孔２６に引っ掛けることができる。これにより、弾性係合片２３をその係合孔２５と係合突部４２との係合を解除する方向に変位させて係合を解除することができる。したがって、弾性係合片２３の基端側からマイナスドライバ５０を挿入して、弾性係合片２３を相手側部材４０から取り外すことができる。 As described above, this embodiment can provide the following effects.
1. The releasing jig 50 can be inserted from the base end side of the elastic engagement piece 23, and the tip of the minus driver 50 can be hooked in the hooking hole 26. Thereby, the engagement can be released by displacing the elastic engagement piece 23 in the direction in which the engagement between the engagement hole 25 and the engagement protrusion 42 is released. Therefore, it is possible to insert the minus driver 50 from the base end side of the elastic engagement piece 23 and remove the elastic engagement piece 23 from the counterpart member 40.

２．係合壁部４１を弾性係合片２３と補助壁２４との間で挟み込むことができる。したがって、係合孔２５と係合突部４２との係合状態を保持することができる。仮に、弾性係合片２３が外側に撓み変形しようとしても、弾性係合片２３が補助壁２４と別体に設けられている場合よりも弾性係合片２３が撓みにくくなるため、係合孔２５と係合突部４２との係合が容易に解除されるおそれがない。 2. The engagement wall portion 41 can be sandwiched between the elastic engagement piece 23 and the auxiliary wall 24. Therefore, the engagement state between the engagement hole 25 and the engagement protrusion 42 can be maintained. Even if the elastic engagement piece 23 is bent outward and deformed, the elastic engagement piece 23 is less likely to bend than when the elastic engagement piece 23 is provided separately from the auxiliary wall 24. There is no possibility that the engagement between the engagement protrusions 25 and the engagement protrusions 42 is easily released.

３．弾性係合片２３を係合壁部４１と反対側に肉盛りすることで係合孔２５の深さ寸法を稼ぐことができる。したがって、弾性係合片２３の弾性力を低下させることなく係合力を高めることができる。 3. The depth of the engagement hole 25 can be increased by building up the elastic engagement piece 23 on the side opposite to the engagement wall portion 41. Therefore, the engagement force can be increased without reducing the elastic force of the elastic engagement piece 23.
