Description

バンド型クランプBand type clamp
 本発明はバンド型クランプに関し、詳しくは、自動車に配索するワイヤハーネスの電線群を結束して、車体パネルに固定するために用いるものである。 The present invention relates to a band-type clamp, and more specifically, is used for binding a wire group of a wire harness routed to an automobile and fixing it to a vehicle body panel.
 従来、電線群の集束体からなるワイヤハーネスを自動車に配索し、所要位置でワイヤハーネスを車体パネル等に固定するためバンド型クランプがワイヤハーネスに取り付けられている。   
 汎用されているバンド型クランプCは図7(A)に示すようにバンド100を突設したバンド係止部101の外面からは車体係止用の羽根状係止部102を突設している。バンド100は、その一面に鋸歯状に係止溝103を連続的に設けると共に他面は平滑面104とし、バンド係止部101にバンド貫通孔105を設け、該バンド貫通孔105の内周面から前記係止溝103に係止する係止片106を突設している。
2. Description of the Related Art Conventionally, a band-type clamp is attached to a wire harness in order to route a wire harness composed of a bundle of electric wires to an automobile and fix the wire harness to a vehicle body panel or the like at a required position.
As shown in FIG. 7A, the widely used band type clamp C has a blade-like locking portion 102 for locking the vehicle body protruding from the outer surface of the band locking portion 101 where the band 100 is protruded. . The band 100 has a serrated engagement groove 103 continuously on one surface and a smooth surface 104 on the other surface, a band through hole 105 is provided on the band engagement portion 101, and an inner peripheral surface of the band through hole 105. A locking piece 106 that locks in the locking groove 103 is provided.
 電線群Wを車体パネルに取り付ける位置に、図7(B)に示すように、前記バンド型クランプCを電線群Wに取り付けている。具体的には、バンド100の平滑面104を電線群への巻付面として巻き付けた後に、前記バンド貫通孔105にバンド100を通し、バンド貫通孔105の内周面から突設した係止片106をバンド100の外周面側の係止溝103に係止して電線群Wをバンド締めして取り付けている。
 このように、電線群Wに取り付けたバンド型クランプCの羽根状係止部102を図7(C)に示すように、車体パネルPの係止孔Hに押し込んで、係止している。
The band clamp C is attached to the electric wire group W at a position where the electric wire group W is attached to the vehicle body panel, as shown in FIG. Specifically, after the smooth surface 104 of the band 100 is wound as a winding surface around the electric wire group, the band 100 is passed through the band through hole 105, and the locking piece protrudes from the inner peripheral surface of the band through hole 105. 106 is locked in the locking groove 103 on the outer peripheral surface side of the band 100, and the wire group W is fastened and attached.
In this way, the blade-like locking portion 102 of the band-type clamp C attached to the wire group W is pushed into the locking hole H of the vehicle body panel P and locked as shown in FIG.
 よって、電線群Wに取り付けているバンド型クランプCの位置と車体パネルPの係止孔Hとの間に位置ずれが発生すると、電線群Wを車体パネルPに取り付けられない問題が発生する。
 しかしながら、バンド100の平滑面104を電線群Wに接触させて巻き付けているため、バンド100に滑りが発生しやすく、バンド型クランプCが電線群Wの長さ方向に横滑りして、車体パネルPの係止孔Hとの間にズレが発生する恐れがある。
Therefore, if a positional shift occurs between the position of the band-type clamp C attached to the wire group W and the locking hole H of the vehicle body panel P, a problem that the wire group W cannot be attached to the vehicle body panel P occurs.
However, since the smooth surface 104 of the band 100 is wound in contact with the wire group W, the band 100 is likely to slip, and the band clamp C slides sideways in the length direction of the wire group W, so that the vehicle body panel P There is a possibility that a deviation occurs between the engagement hole H and the engagement hole H.
 多数の電線群を集束して配線する場合、従来、図8(A)に示すように、電線群Wに予め粘着テープT1を巻き付けて結束し、該粘着テープT1の外周面にバンド型クランプCを取り付けている場合が多い。また、粘着テープを巻き付けて電線群を予め結束していない場合には、図8(B)に示すように、バンド型クランプの取付位置に粘着テープT2を先に巻き付けておき、この下巻きした粘着テープT2の外周面にバンド型クランプCを巻き付けて取り付け、滑りにくくしている。
 しかしながら、前記のように粘着テープT1、T2を用いるとテープ巻作業が必要となり、かつ、テープ代金がかかり、コストアップの要因となる。
When a large number of electric wire groups are converged and wired, conventionally, as shown in FIG. 8A, an adhesive tape T1 is wound around the electric wire group W in advance and bound, and a band-type clamp C is attached to the outer peripheral surface of the adhesive tape T1. Are often installed. In addition, when the adhesive tape is wound and the electric wire group is not bundled in advance, as shown in FIG. 8 (B), the adhesive tape T2 is first wound around the attachment position of the band-type clamp, and this is wound downward. A band-type clamp C is wound around and attached to the outer peripheral surface of the adhesive tape T2, thereby preventing slippage.
However, when the adhesive tapes T1 and T2 are used as described above, a tape winding operation is required, and a tape cost is required, resulting in a cost increase.
 この種のバンド型クランプを、電線群に外装したコルゲートチューブに取り付けたものとして、特開平11-255260号公報に図9に示すバンド型クランプC-1が提案されている。
 該バンド型クランプC-1では、コルゲートチューブに巻き付けるバンド200の平滑面201に、コルゲートチューブの凹部に対応する位置に凸部202を設け、コルゲートチューブにバンド200を位置決めして取り付けるようにしている。
 しかしながら、電線群にコルゲートチューブを外装していない場合に用いるバンド型クランプとして、横滑り防止対策を施したバンド型クランプは提案されていない。
 かつ、前記図9に示すバンド型クランプC-1を用いても、凸部202の間に電線を通すだけであるため、電線の横滑り防止機能はない。
Japanese Patent Application Laid-Open No. 11-255260 proposes a band-type clamp C-1 shown in FIG. 9 as an example in which this type of band-type clamp is attached to a corrugated tube packaged around an electric wire group.
In the band type clamp C-1, a convex portion 202 is provided at a position corresponding to a concave portion of the corrugated tube on the smooth surface 201 of the band 200 wound around the corrugated tube, and the band 200 is positioned and attached to the corrugated tube. .
However, as a band-type clamp used when the corrugated tube is not externally mounted on the electric wire group, a band-type clamp with a measure for preventing skidding has not been proposed.
Further, even if the band-type clamp C-1 shown in FIG. 9 is used, since the electric wire is only passed between the convex portions 202, there is no function of preventing the electric wire from sliding.
特開平11-255260号公報JP-A-11-255260
 本発明は前記問題に鑑みてなされたもので、コルゲートチューブで電線群を外装しておらず、また、粘着テープで電線群を結束していない場合に、前記図8(B)に示すようにバンド型クランプの取付位置に下巻テープを巻き付けることなく、バンド型クランプを取り付けても、電線群に対して横滑りを発生させないバンド型クランプを提供することを課題としている。 The present invention has been made in view of the above problems. When the corrugated tube does not cover the electric wire group and the electric wire group is not bound with the adhesive tape, as shown in FIG. An object of the present invention is to provide a band type clamp that does not cause a side slip with respect to the electric wire group even if the band type clamp is attached without winding the lower tape on the attachment position of the band type clamp.
 前記課題を解決するため、本発明は、複数本の電線の外周に巻き付けて電線群として結束すると共に該電線群を車体に固定するバンド型クランプであって、
 バンド係止部と、該バンド係止部から突出するバンドと、前記バンド係止部から突設する車体係止部を備えた樹脂成形品からなり、
 前記バンドには、前記電線群への巻付面となるバンドの一面に、少なくとも幅方向の両側に沿って間隔をあけて凸リブを設け、かつ、これらの凸リブは幅方向で千鳥配置として、長さ方向に隣接する凸リブの間の電線挿通路に電線を蛇行させて通すようにし、
 前記バンドの巻付面に対して直交する幅方向の両端面または巻付面と反対面に係止溝を連続的に設け、
 前記バンド係止部のハウジング内にバンド貫通孔を備え、該貫通孔の内周面から突出して前記係止溝に係止する係止片を突設し、かつ、前記ハウジングの外面に前記車体係止部を突設していることを特徴とするバンド型クランプを提供している。
In order to solve the above-mentioned problem, the present invention is a band-type clamp that is wound around the outer periphery of a plurality of electric wires and bound as a group of electric wires and fixes the electric wires group to a vehicle body,
A resin molded product comprising a band locking part, a band protruding from the band locking part, and a vehicle body locking part protruding from the band locking part,
The band is provided with convex ribs on one side of the band that is a winding surface around the electric wire group at intervals along at least both sides in the width direction, and these convex ribs are staggered in the width direction. , Let the wire meander through the wire insertion path between the convex ribs adjacent in the length direction,

 前記のように、バンドの電線群への巻付面において、凸リブを長さ方向に間隔をあけると共に、幅方向で千鳥配置とすると、凸リブの間を通す電線はバンドを蛇行して横断する。よって、バンドに電線群の長さ方向の横滑り方向への負荷がかかっても、幅方向の凸リブの一方が電線に引っ掛かり、バンド型クランプの横滑りを防止できる。 As described above, on the winding surface of the band to the electric wire group, when the convex ribs are spaced in the length direction and arranged in a staggered manner in the width direction, the electric wires passing between the convex ribs meander and cross the band. To do. Therefore, even if a load is applied to the band in the side-sliding direction in the length direction of the electric wire group, one of the convex ribs in the width direction is caught on the electric wire, and the side-slip of the band-type clamp can be prevented.
 バンドに設ける連続した係止溝を、前記凸リブを設けた巻付面に対して直交方向の両端面に設けた場合、バンド係止部のハウジングに設けたバンド貫通孔の両側面から係止片を突設している。
 一方、バンドに設ける連続した係止溝を、前記凸リブを設けた巻付面と反対側の外周面に設けた場合、バンド係止部のバンド貫通孔の上面から係止片を突設している。

On the other hand, when the continuous locking groove provided in the band is provided on the outer peripheral surface opposite to the winding surface provided with the convex rib, the locking piece protrudes from the upper surface of the band through hole of the band locking portion. ing.
 前記凸リブは、前記電線群のうちの最大外径の電線を挿通できる間隔を長さ方向にあけている。
 前記設定とすることにより、最大外径の電線が電線群の外周に位置しても、該電線を凸リブの間を通してバンドに対して蛇行させて横断させることができる。外径が小さい電線は複数本を隣接する凸リブの1つの電線挿通路に通しても、これらをまとめて蛇行させることができる。
The convex rib has an interval in the length direction through which the electric wire having the maximum outer diameter in the electric wire group can be inserted.
By setting as described above, even when the electric wire having the maximum outer diameter is located on the outer periphery of the electric wire group, the electric wire can be caused to meander and cross the band through the convex ribs. Even if a plurality of electric wires having a small outer diameter are passed through one electric wire insertion passage of adjacent convex ribs, they can be meandered together.

Wn) and is not covered with a corrugated tube, The band-type clamp 1 is attached to these electric wire groups 10 in a disassembled state in which the lower winding tape is not partially wound around the attachment position. And the attachment position of this band type | mold clamp 1 is a position corresponding to the locking hole provided in the vehicle body panel when wiring the wire harness which consists of the focusing body of these electric wire groups 10 to a motor vehicle.
 バンド型クランプ1は樹脂成形品からなり、図2に示すように、バンド係止部2と、バンド係止部2から突出するバンド3と、バンド係止部2からバンド3と直交方向に突設する車体係止部4を一体的に備えている。 The band-type clamp 1 is made of a resin molded product. As shown in FIG. 2, the band-clamping part 2, the band 3 protruding from the band-locking part 2, and the band-locking part 2 protruding in a direction perpendicular to the band 3 are provided. The vehicle body locking part 4 to be provided is integrally provided.
 前記バンド係止部2はボックス状のハウジング11にバンド貫通孔12を備え、該バンド貫通孔12を囲む内周面の左右両側から係止片13を突設している。バンド貫通孔12の一端側からバンド3が突出し、ハウジング11の外面から羽根状の車体係止部4を突設している。該車体係止部4はハウジング11から突設した軸部4aの先端から両側に羽根部4bを折り返し状に設け、各羽根部4bの先端に係止段部4cを設けている。 The band locking portion 2 has a band-shaped through hole 12 in a box-shaped housing 11, and locking pieces 13 project from left and right sides of the inner peripheral surface surrounding the band through-hole 12. A band 3 protrudes from one end side of the band through-hole 12, and a blade-like vehicle body locking portion 4 protrudes from the outer surface of the housing 11. The vehicle body locking portion 4 is provided with a wing portion 4b in a folded shape on both sides from the tip of a shaft portion 4a protruding from the housing 11, and a locking step portion 4c is provided at the tip of each blade portion 4b.
 前記バンド3には、図3(A)に拡大して示すように、電線群10への巻付面15に幅方向の両端面16はそれぞれ鋸歯状に係止し連続した係止溝17を設けている。これら係止溝17にはバンド係止部2のバンド貫通孔12にバンド3を挿入した際に、係止片13が係止する。 As shown in an enlarged view in FIG. 3A, the band 3 has both end surfaces 16 in the width direction on the winding surface 15 around the electric wire group 10 in a sawtooth shape, and a continuous locking groove 17 is provided. Provided. When the band 3 is inserted into the band through hole 12 of the band locking portion 2, the locking piece 13 is locked into these locking grooves 17.
 前記バンド3の巻付面15には、幅方向の両端縁に沿って、夫々長さ方向の略全長にそって、一定間隔をあけて凸リブ18、凸リブ19を突設し、凸リブを2列で設けている。
 これら両側の凸リブ18と19とは図3(B)に示すように、幅方向で直線上に位置させず、千鳥配置とし、一端側の凸リブ18と対応する他方側は隣接した凸リブ19に挟まれた電線挿通路20としている。同様に隣接する凸リブ18の間の電線挿通路21は凸リブ19と対応する位置に設けている。
Convex ribs 18 and convex ribs 19 project from the winding surface 15 of the band 3 at regular intervals along substantially the entire length in the longitudinal direction along both end edges in the width direction. Are provided in two rows.
As shown in FIG. 3 (B), these convex ribs 18 and 19 on both sides are not positioned on a straight line in the width direction, but are arranged in a staggered manner, and the other side corresponding to the convex rib 18 on one end side is an adjacent convex rib. An electric wire insertion path 20 sandwiched between 19 is used. Similarly, the wire insertion passage 21 between the adjacent convex ribs 18 is provided at a position corresponding to the convex rib 19.
 前記凸リブ18、19は図3(C)に示すように台円錐状に突出させている。
 本実施形態では、バンド3の幅Wを6.4mmとし、凸リブ18、19の幅方向の突出寸法L1を1.0mmとし、凸リブ18、19の突出高さHを0.4mmとしている。
The convex ribs 18 and 19 are projected in a conical shape as shown in FIG.
In this embodiment, the width W of the band 3 is 6.4 mm, the protruding dimension L1 in the width direction of the convex ribs 18 and 19 is 1.0 mm, and the protruding height H of the convex ribs 18 and 19 is 0.4 mm. .
 前記長さ方向に隣接する凸リブ18の間の電線挿通路21、凸リブ19の間の電線挿通路20の寸法L2は0.6mmとしている。この寸法L2は巻き付ける電線群10の中で最大外径を有する電線wの外径と略等しくしていることが好ましい。 The dimension L2 of the electric wire insertion path 21 between the convex ribs 18 adjacent in the length direction and the electric wire insertion path 20 between the convex ribs 19 is 0.6 mm. This dimension L2 is preferably substantially equal to the outer diameter of the electric wire w having the maximum outer diameter in the electric wire group 10 to be wound.
 前記形状としたバンド型クランプ1をバラバラの電線w1~wnからなる電線群10に巻き付ける際に、図4に示すように、まず、バンド3を延在させた状態で、各電線wを凸リブ18間の電線挿通路21に通し、ついで、凸リブ19の間の電線挿通路20に通す。 電線挿通路21と20とはバンド3を直線状に横断する位置に設けていないため、各電線wはバンド3を蛇行して横断することとなる。かつ、該横断状態で隣接する凸リブ18の間および凸リブ19の間で保持される。 When the band-shaped clamp 1 having the above-described shape is wound around the electric wire group 10 composed of the separated electric wires w1 to wn, as shown in FIG. The wire 18 is passed through the wire insertion passage 21 between the 18, and then passed through the wire insertion passage 20 between the convex ribs 19. Since the wire insertion paths 21 and 20 are not provided at positions that cross the band 3 linearly, each wire w meanders and crosses the band 3. And it hold | maintains between the adjacent convex ribs 18 and the convex ribs 19 in this crossing state.
 前記のように、バンド3に電線wを通した状態でバンド3の巻付面15を内周面として円弧状に巻き、バンド3の先端からバンド係止部2のバンド貫通孔12に通して引っ張る。これにより、バンド3の幅方向両端の係止溝17に係止片13が両側から係止して、電線群10をバンド締めで締結する。   As described above, the wire 3 is wound in an arc shape with the winding surface 15 of the band 3 as the inner peripheral surface while the electric wire w is passed through the band 3, and the band 3 is passed through the band through hole 12 of the band locking portion 2 from the tip. pull. Accordingly, the locking pieces 13 are locked from both sides in the locking grooves 17 at both ends in the width direction of the band 3, and the electric wire group 10 is fastened by band tightening. *
 このように、バンド3を電線群10に巻き付けることにより、バンド3に電線群10の長さ方向に横滑りする負荷がかかっても、電線wを蛇行させてバンド3を横断させているため、凸リブ18または凸リブ19に電線wが引っ掛かり、バンド3の横滑りを阻止することができる。
 よって、バンド型クランプ1を電線群10に対して設定した取付位置に保持でき、自動車内に配索時に、車体パネルに設けた係止孔に正確に位置合わせすることができる。
In this way, by winding the band 3 around the electric wire group 10, the electric wire w meanders and crosses the band 3 even if the band 3 is subjected to a side slide in the length direction of the electric wire group 10. The electric wire w is caught by the rib 18 or the convex rib 19, and the side slip of the band 3 can be prevented.
Therefore, the band-type clamp 1 can be held at the mounting position set with respect to the electric wire group 10, and can be accurately aligned with the locking hole provided in the vehicle body panel when being wired in the automobile.
 図5に第二実施形態を示す。
 凸リブ18、19を夫々断面菱形形状とし、これら凸リブ18、19を千鳥配置することで、凸リブ18の一辺18aと凸リブ19の一辺19aとを平行配置し、この隙間に電線wを通すことで、電線を保持して横ずれを防止している。菱形の凸リブ18、19は各頂点となるエッジにアールRを設けて電線wに損傷を与えないようにしている。
 他の構成は第一実施形態と同様であるため、説明を省略する。
FIG. 5 shows a second embodiment.
The convex ribs 18 and 19 have a rhombus shape in cross section, and the convex ribs 18 and 19 are arranged in a staggered manner, whereby one side 18a of the convex rib 18 and one side 19a of the convex rib 19 are arranged in parallel, and the electric wire w is connected to this gap. By passing it through, the electric wire is held to prevent lateral slippage. The rhombic convex ribs 18 and 19 are provided with a radius R at the edge which is the apex so as not to damage the electric wire w.
Since other configurations are the same as those of the first embodiment, description thereof is omitted.
 図6に第二実施形態を示す。
 第二実施形態では、3列の凸リブ18、19、25を設けている。 
 即ち、ベルト3の巻付面15に、幅方向の両端に沿って、長さ方向に間隔をあけて凸リブ18、19を設け、中央部に長さ方向に沿って間隔をあけて凸リブ25を設けている。
幅方向両側の凸リブ18と19とは対向位置に配置し、中央部の凸リブ25を凸リブ18、19に対して千鳥配置している。
 前記凸リブ18、19、25はいずれも円柱状としている。
FIG. 6 shows a second embodiment.
In the second embodiment, three rows of convex ribs 18, 19, and 25 are provided.
That is, convex ribs 18 and 19 are provided on the winding surface 15 of the belt 3 at both ends in the width direction at intervals along the length direction, and at the center portion with intervals along the length direction. 25 is provided.
The convex ribs 18 and 19 on both sides in the width direction are arranged at opposing positions, and the central convex ribs 25 are arranged in a staggered manner with respect to the convex ribs 18 and 19.
The convex ribs 18, 19 and 25 are all cylindrical.
 前記のように、凸リブを3列設けると、長さ方向に隣接する凸リブ18の間、凸リブ25の間、凸リブ19の間の電線挿通路を通す電線wはS字状に蛇行することとなり、より確実に電線群に対するバンド型クランプの横ずれを防止することができる。 As described above, when three rows of convex ribs are provided, the electric wires w passing through the wire insertion paths between the convex ribs 18 adjacent to each other in the length direction, between the convex ribs 25, and between the convex ribs 19 meander in an S shape. Therefore, the lateral displacement of the band-type clamp with respect to the electric wire group can be prevented more reliably.
