次に、以上の構成からなるノックアウト構造２およびノックアウト付装置４の作用効果について説明する。このノックアウト構造２とかノックアウト付装置４によると、ノックアウト付部材３の筒２ｇに、コネクタ１０１（取着体、貫通体１）のねじ部１ａが螺合可能な螺合部２ｅを設け、ノックアウト２ｃを抜くにあたって、コネクタ１０１を螺進させてそのコネクタ１０１の先端面押圧部１ｂでノックアウト２ｃを徐々に押圧することで、このノックアウト２ｃを小さな力で簡単に抜くことができる。また、このノックアウト構造２は、従来のような衝撃による破断方式とは異なるため、連結部２ｄの破断が壁部２ａの割れに進展する虞がない。 Next, the effect of the knockout structure 2 and the knockout device 4 having the above-described configuration will be described. According to the knockout structure 2 or the device 4 with knockout, a screwing portion 2e into which the screw portion 1a of the connector 101 (attachment body, penetrating body 1) can be screwed is provided on the cylinder 2g of the member 3 with knockout. When the connector 101 is pulled out, the knockout 2c can be easily pulled out with a small force by screwing the connector 101 and gradually pressing the knockout 2c with the tip surface pressing portion 1b of the connector 101. In addition, since the knockout structure 2 is different from the conventional fracture method by impact, there is no possibility that the fracture of the connecting portion 2d progresses to the crack of the wall portion 2a.

また、部分押圧手段５により、先端面押圧部１ｂでノックアウト２ｃの板面の周回りの一部を部分的に押圧することで、その押圧される側から、連結部２ｄは、順に破断される（図４、図５参照）。このため、この部分押圧手段５によって、ノックアウト２ｃを一層小さな力で抜くことができる。なお、図示実施の形態においては、コネクタ１０１を螺合部２ｅにねじ込むことで、ノックアウト２ｃは、抜かれるとともに除去される（図６参照）。 Further, the partial pressing means 5 partially presses a part of the periphery of the plate surface of the knockout 2c with the tip surface pressing portion 1b, so that the connecting portion 2d is sequentially broken from the pressed side. (See FIGS. 4 and 5). For this reason, the knockout 2c can be pulled out with a smaller force by the partial pressing means 5. In the illustrated embodiment, the knockout 2c is removed and removed by screwing the connector 101 into the screwing portion 2e (see FIG. 6).

また、ノックアウト付部材３に取付け固定されるコネクタ１０１（取着体）を、ノックアウト２ｃを抜くための貫通体として利用することで、別途貫通体を設ける必要がなく、また、その貫通体でノックアウト２ｃを抜く作業が不要となる。 Further, by using the connector 101 (attachment body) attached and fixed to the member 3 with knockout as a through body for pulling out the knockout 2c, it is not necessary to provide a separate through body, and the through body can be used for knockout. The operation | work which extracts 2c becomes unnecessary.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、ノックアウト２ｃと壁部２ａ側とを連結する連結部２ｄは、図７〜図９に示すように、ノックアウト２ｃの周回り方向の一部が厚肉に形成されて、その厚肉部分２ｍが、ノックアウト２ｃが抜かれた後にも破断されることなくノックアウト２ｃと壁部２ａ側とを繋げてもよい。すなわち、図９に示すように、ノックアウト２ｃは、厚肉部分２ｍがヒンジとなって開いてもよい。これにより、ノックアウト２ｃが抜かれたときに、そのノックアウト２ｃが不用意に飛んで人に当たったり隙間に入り込んだりすることがない。ここで、ノックアウト２ｃは、邪魔にならなければ壁部２ａ側と繋がった状態のまま残してもよく、また、手で折り取るようにして除去してもよい。そして、ノックアウト２ｃを壁部２ａ側と繋がった状態のまま残すと、そのノックアウト２ａは、ゴミになることがない。 In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, as shown in FIG. 7 to FIG. 9, the connecting portion 2 d that connects the knockout 2 c and the wall portion 2 a side is formed such that a part in the circumferential direction of the knockout 2 c is thick, and the thick portion 2 m However, the knockout 2c and the wall 2a side may be connected without being broken even after the knockout 2c is removed. That is, as shown in FIG. 9, the knockout 2c may be opened with the thick portion 2m serving as a hinge. Thereby, when the knockout 2c is pulled out, the knockout 2c does not accidentally fly and hit a person or enter a gap. Here, the knockout 2c may be left in a state of being connected to the wall 2a side as long as it does not get in the way, or may be removed by folding it by hand. If the knockout 2c is left connected to the wall 2a side, the knockout 2a does not become garbage.

また、図１０〜図１６に示すように、ノックアウト付部材３は、コネクタ１０１（取着体、貫通体１）の螺進に伴い、既述の部分押圧手段５によってノックアウト２ｃの周回りの一部が部分的に押圧されて、その押圧された側から破断される連結部２ｄの残された部分を支点とした回動により傾く（つまり、コネクタ１０１の螺進による進行方向の側に傾く）、ノックアウト２ｃが、所定の角度を越えて傾くのを阻止する、阻止部３ｆを有してもよい。詳細には、ノックアウト付部材３は、配線ボックス３０１であって、貫通孔２ｂは、配線材の導入孔となっている。そして、配線ボックス３０１（ノックアウト付部材３）は、その側壁３ｃまたは底壁３ｄ（図示実施の形態においては、側壁３ｃ）の内面側に、コネクタ１０１（取着体、貫通体１）の螺進による進行方向に対して傾斜して、貫通孔２ｂから導入された配線材を配線ボックス３０１の中央側に案内する、案内面３ｇを有し、その案内面３ｇが前記阻止部３ｆを兼ねる。図示実施の形態においては、ノックアウト付部材３の左右の側壁３ｃ、３ｃが上下の端部（つまり、壁部２ａとしての上壁３ａとか下壁３ｂの側の端部）にて外方に膨出した膨出部３ｅ、３ｅの内面であって、側壁３ｃの中央寄りに位置する傾斜面である面３ｈが、前記案内面３ｇとなり、かつ、前記阻止部３ｆとなっている（図１２、図１３参照）。そして、この面３ｈ（案内面３ｇ）は、ノックアウト２ｃの奥側において、ノックアウト２ｃに対して部分的に覆い被さるように（つまり、コネクタ１０１の螺進による進行方向から見てノックアウト２ｃと部分的に重なるように）傾斜している。また、連結部２ｄは、ノックアウト２ｃの全周を壁部２ａ（上壁３ａ、下壁３ｂ）側と連結するとともに、ノックアウト２ｃの周回り方向の一部が厚肉に形成されている。そして、ノックアウト２ｃ（および筒２ｇ）は、各壁部２ａ、２ａ（上壁３ａ、下壁３ｂ）において、左右に２個並ぶように設けられており、それらノックアウト２ｃ、２ｃの周回り方向における、壁部２ａ（上壁３ａ、下壁３ｂ）の中央部Ｐ側に位置する一部が、厚肉に形成された厚肉部分２ｍとなっている（図１１および図１３〜図１５参照）。 Further, as shown in FIGS. 10 to 16, the member 3 with a knockout is rotated around the knockout 2 c by the partial pressing means 5 described above as the connector 101 (attachment body, penetrating body 1) is screwed. The portion is partially pressed and tilted by rotation with the remaining portion of the connecting portion 2d broken from the pressed side as a fulcrum (that is, tilted toward the traveling direction due to screwing of the connector 101). The knockout 2c may have a blocking portion 3f that prevents the knockout 2c from tilting beyond a predetermined angle. More specifically, the knockout member 3 is a wiring box 301, and the through hole 2b is a wiring material introduction hole. The wiring box 301 (member with knockout 3) is screwed on the inner surface side of the side wall 3c or bottom wall 3d (side wall 3c in the illustrated embodiment) of the connector 101 (attachment body, penetrating body 1). It has a guide surface 3g that is inclined with respect to the traveling direction and guides the wiring material introduced from the through-hole 2b to the center side of the wiring box 301, and the guide surface 3g also serves as the blocking portion 3f. In the illustrated embodiment, the left and right side walls 3c, 3c of the member 3 with knockout bulge outward at upper and lower ends (that is, the upper wall 3a as the wall 2a or the end on the lower wall 3b side). A surface 3h which is an inner surface of the protruding bulges 3e and 3e and is an inclined surface located near the center of the side wall 3c serves as the guide surface 3g and serves as the blocking portion 3f (FIG. 12, (See FIG. 13). The surface 3h (guide surface 3g) is partially covered with the knockout 2c on the inner side of the knockout 2c (that is, the knockout 2c and the knockout 2c as viewed from the traveling direction by the screwing of the connector 101). Incline) Further, the connecting portion 2d connects the entire circumference of the knockout 2c with the wall 2a (upper wall 3a, lower wall 3b) side, and a part in the circumferential direction of the knockout 2c is formed thick. The knockouts 2c (and the cylinder 2g) are provided so as to be arranged in two on the left and right in each wall 2a, 2a (upper wall 3a, lower wall 3b), and in the circumferential direction of the knockouts 2c, 2c. Part of the wall 2a (upper wall 3a, lower wall 3b) located on the center P side is a thick part 2m formed thick (see FIG. 11 and FIGS. 13 to 15). .

そして、この図１０〜図１６に示す例にあっては、コネクタ１０１（取着体、貫通体１）の螺進に伴って、連結部２ｄが厚肉部分２ｍを残して破断されるとともに、ノックアウト２ｃが、厚肉部分２ｍを支点として、コネクタ１０１の螺進による進行方向側へと回動し、その回動により、初期位置（図示実施の形態においては、ノックアウト２ｃの内側面が壁部２ａの内壁面と面一の状態にある位置）に対して傾く（図１５参照）。すなわち、ノックアウト２ｃは、厚肉部分２ｍがヒンジとなって開き始める。そして、ノックアウト２ｃは、破断された側の周縁部が、阻止部３ｆ（案内面３ｇ）に当たって、それ以上傾くのが阻止される（つまり、ノックアウト２ｃが、前記周縁部が阻止部３ｆに当たった時の、壁部２ａとのなす角度を越えて、傾くのが阻止される）。この状態で、さらにコネクタ１０１（取着体、貫通体１）を螺進させると、コネクタ１０１の先端面押圧部１ｂの、ノックアウト２ｃを押圧する押圧力が、厚肉部分２ｍに集中し、その結果、厚肉部分２ｍが破断される。こうして、連結部２ｄは、その全体が破断され、その後、抜かれたノックアウト２ｃは除去される（図１６参照）。このように、阻止部３ｆにより、ノックアウト２ｃが所定の角度を越えて傾くのを阻止することで、コネクタ１０１（取着体、貫通体１）の先端面押圧部１ｂの押圧力が、連結部２ｄの破断されていない一部分（厚肉部分２ｍ）に集中し、連結部２ｄの全体を確実に破断することができる。しかも、案内面３ｇが阻止部３ｆを兼ねることから、別途阻止部３ｆを設ける必要がない。なお、図示実施の形態においては、膨出部３ｅの内面における、側壁３ｃの中央寄りに位置する傾斜面である面３ｈが、案内面３ｇであり阻止部３ｆとなっているが、面３ｈを、壁部２ａの壁面と平行となるように設ければ、この面３ｈは、阻止部３ｆであっても案内面３ｇとはならない。また、配線ボックス３０１（ノックアウト付部材３）は、底壁３ｄの内面側に、前記案内面を有し、その案内面が前記阻止部３ｆを兼ねてもよい。また、阻止部３ｆは、前記面３ｈとか前記案内面でなくてもよく、例えば、配線ボックス３０１（ノックアウト付部材３）の側壁３ｃや底壁３ｄの内面側に設けられた凸部とか突起物などであってもよい。 In the example shown in FIGS. 10 to 16, as the connector 101 (attachment body, penetrating body 1) is screwed, the connecting portion 2 d is broken leaving the thick portion 2 m, The knockout 2c rotates about the thick portion 2m as a fulcrum toward the traveling direction side by the screwing of the connector 101, and by the rotation, the initial position (in the illustrated embodiment, the inner surface of the knockout 2c is the wall portion. 2a) (see FIG. 15). That is, in the knockout 2c, the thick portion 2m begins to open as a hinge. In the knockout 2c, the peripheral portion on the broken side hits the blocking portion 3f (guide surface 3g) and is prevented from further tilting (that is, the knockout 2c hits the blocking portion 3f. Inclination beyond the angle formed by the wall 2a at the time is prevented). In this state, when the connector 101 (attachment body, penetrating body 1) is further screwed, the pressing force pressing the knockout 2c of the tip surface pressing portion 1b of the connector 101 is concentrated on the thick portion 2m, As a result, the thick portion 2m is broken. Thus, the entire connecting portion 2d is broken, and then the extracted knockout 2c is removed (see FIG. 16). In this way, the blocking portion 3f prevents the knockout 2c from tilting beyond a predetermined angle, so that the pressing force of the distal end surface pressing portion 1b of the connector 101 (attachment body, penetrating body 1) is changed to the connecting portion. It is possible to concentrate on the part of 2d that is not broken (thick part 2m) and to reliably break the entire connecting part 2d. In addition, since the guide surface 3g also serves as the blocking portion 3f, there is no need to separately provide the blocking portion 3f. In the illustrated embodiment, the surface 3h which is an inclined surface located near the center of the side wall 3c on the inner surface of the bulging portion 3e is the guide surface 3g and serves as the blocking portion 3f. If provided so as to be parallel to the wall surface of the wall portion 2a, the surface 3h does not become the guide surface 3g even if it is the blocking portion 3f. Further, the wiring box 301 (member with knockout 3) may have the guide surface on the inner surface side of the bottom wall 3d, and the guide surface may also serve as the blocking portion 3f. Further, the blocking portion 3f may not be the surface 3h or the guide surface. For example, the blocking portion 3f may be a protrusion or protrusion provided on the inner surface side of the side wall 3c or the bottom wall 3d of the wiring box 301 (knockout member 3). It may be.

また、ノックアウト２ｃに設けられる突起２ｊ（２ｆ）、２ｋ（２ｆ）は、貫通体１の螺進に伴って、ノックアウト２ｃの周回りの一方向の順に先端面押圧部１ｂが押圧するように、その高さが設定されているが、例えば、複数の突起２ｆ、２ｆが、高さ違いにあって、その高さがノックアウト２ｃの周回りの一方向の順に並んでいなくともよい。 Further, the protrusions 2j (2f) and 2k (2f) provided on the knockout 2c are pressed by the tip surface pressing portion 1b in the order of one direction around the circumference of the knockout 2c as the penetrating body 1 is screwed. Although the height is set, for example, the plurality of protrusions 2f and 2f may have different heights, and the heights may not be arranged in one direction around the circumference of the knockout 2c.

また、ノックアウト２ｃには、第１突起２ｊ（２ｆ）と第２突起２ｋ（２ｆ）との複数の突起が設けられているが、例えば、第２突起２ｋは設けられず第１突起２ｊのみが設けられるというように、突起２ｆが、一つのみ設けられてもよい。 Further, the knockout 2c is provided with a plurality of projections of a first projection 2j (2f) and a second projection 2k (2f). For example, the second projection 2k is not provided and only the first projection 2j is provided. As is provided, only one protrusion 2f may be provided.

また、部分押圧手段５は、上述の構成以外に、図１７とか図１８に示すように、ねじ部１ａと螺合部２ｅとの螺合の軸心６回りにその軸心６と直交するように形成された、先端面押圧部１ｂと、軸心６に対して傾斜するように形成されて、先端面押圧部１ｂに押圧される、ノックアウト２ｃの被押圧面２ｎとからなってもよい。すなわち、図１７に示す例では、ノックアウト２ｃの被押圧面２ｎが、軸心６と直交する壁部２ａの壁面に対して、傾斜することで、その被押圧面２ｎが、前記軸心６に対して傾斜する。また、この場合には、図１７に示す以外に、ノックアウト２ｃが、ノックアウト本体と、そのノックアウト本体とは別体の、被押圧面２ｎを形成する被押圧面形成体とから構成されてもよい。また、図１８に示す例では、前記軸心６が、壁部２ａの壁面に対して直交することなく傾斜することで、ノックアウト２ｃの被押圧面２ｎが、前記軸心６に対して傾斜することとなる。 In addition to the above-described configuration, the partial pressing means 5 is orthogonal to the axial center 6 around the axial center 6 of the threaded portion 1a and the threaded portion 2e as shown in FIGS. The tip surface pressing portion 1b formed on the shaft 6 and the pressed surface 2n of the knockout 2c formed so as to be inclined with respect to the axis 6 and pressed by the tip surface pressing portion 1b may be included. That is, in the example shown in FIG. 17, the pressed surface 2 n of the knockout 2 c is inclined with respect to the wall surface of the wall portion 2 a orthogonal to the axial center 6, so that the pressed surface 2 n is in contact with the axial center 6. Inclines against. In this case, in addition to the one shown in FIG. 17, the knockout 2c may be composed of a knockout main body and a pressed surface forming body that forms a pressed surface 2n that is separate from the knockout main body. . In the example shown in FIG. 18, the pressed surface 2n of the knockout 2c is inclined with respect to the axial center 6 because the axial center 6 is inclined without being orthogonal to the wall surface of the wall portion 2a. It will be.

また、図示を省略するが、部分押圧手段５は、ねじ部１ａと螺合部２ｅとの螺合の軸心６に対して傾斜するように形成された、先端面押圧部１ｂと、軸心６と直交するように形成されて、先端面押圧部１ｂに押圧される、ノックアウト２ｃの被押圧面２ｎとからなってもよい。 Although not shown in the drawings, the partial pressing means 5 includes a tip surface pressing portion 1b and an axis that are formed so as to be inclined with respect to the screw shaft center 6 of the screw portion 1a and the screw portion 2e. 6 and may be composed of a pressed surface 2n of the knockout 2c that is formed so as to be orthogonal to 6 and pressed by the tip surface pressing portion 1b.
