Description

本発明は、各種電子・電気機器において、電磁波障害対策として電線を内部に通す磁性体を固定するために使用される雑音電流吸収具用の保持具に関する。   The present invention relates to a holder for a noise current absorber used in various electronic / electrical devices to fix a magnetic body that passes an electric wire as an electromagnetic interference countermeasure.

従来、電線にながれる電流の雑音を吸収して雑音吸収効果を得る方法として、電線の周囲を取り囲むように磁性体を外嵌させ、この磁性体により電線を流れる雑音電流を吸収する(雑音吸収効果を得る)技術が知られている。
このような雑音電流吸収具では、収納部に磁性体を収納し、筒状体の内部を電線が通過するように閉じると、二分割された磁性体の接合面が合わさることで磁気的に閉磁路となり、雑音吸収効果を得ることができる。 Conventionally, as a method of obtaining a noise absorption effect by absorbing the noise of the current flowing through the electric wire, a magnetic material is externally fitted around the electric wire, and the noise current flowing through the electric wire is absorbed by this magnetic material (noise absorption effect Technology) is known.
In such a noise current absorber, when the magnetic body is stored in the storage portion and the inside of the cylindrical body is closed so that the electric wire passes, the joint surface of the two divided magnetic bodies is combined to magnetically close the magnetic field. It becomes a road and a noise absorption effect can be obtained.

一方、分割型ホルダーの半円形窓部中央に外方に延びる樋状片を一体に設け、この樋状片を電線に両側から当接させて、樋状片の上から束線バンドで緊縛して電線を固定するホルダーがある（特許文献１参照）。このようなホルダーでは、電線を簡単に確実にホルダーを固定できる。   On the other hand, a hook-shaped piece extending outward is integrally provided in the center of the semicircular window portion of the split holder, and this hook-shaped piece is brought into contact with the electric wire from both sides, and is bound with a bundle band from above the hook-shaped piece. There is a holder for fixing the electric wire (see Patent Document 1). With such a holder, the electric wire can be easily and securely fixed.

特開平７−２４０３１７号公報Japanese Patent Laid-Open No. 7-240317

しかし、このような構造であると、束線バンドを緊縛して、電線をホルダーに固定する場合に、該電線の径が細かったり、電線とホルダーとを固定を確実に行うために束線バンドの緊縛を強くすると、図９に示す如く、ホルダーの周壁において、樋状片が設けられていない側が離間してしまい、その結果、ホルダー内部に収納されるコア片同士が離れてしまう問題がある。このようにコア片同士が離れてしまうと、分割されたコア片同士で磁気的な閉磁路が形成されなくなってしまうため、雑音吸収効果が得られなくなってしまう。   However, with such a structure, when the bundled band is tightly bound and the electric wire is fixed to the holder, the diameter of the electric wire is small or the bundled band is used to securely fix the electric wire and the holder. As shown in FIG. 9, there is a problem in that the side on which the hook-shaped piece is not provided is separated from the peripheral wall of the holder, and as a result, the core pieces stored inside the holder are separated from each other. . If the core pieces are separated from each other in this way, a magnetic closed magnetic path is not formed between the divided core pieces, and thus a noise absorbing effect cannot be obtained.

本発明は、上記問題を解決するためになされたものであり、雑音吸収効果が確実に得られる保持具を提供することにある。   The present invention has been made to solve the above problems, and it is an object of the present invention to provide a holder capable of reliably obtaining a noise absorbing effect.

前記保持片係合部は、前記保持片と係合した際に、前記保持片の三方に接する形状とされ、前記三方のうち、二方は、前記保持片の前記保持片係合部に対する挿し込み方向及び前記電線の挿通方向の双方に直交する方向について前記保持片(22)の両側とされ、残りの一方は、前記電線の挿通方向について前記保持片を挟んで前記電線固定部とは反対側とされていることを特徴とする。 Coercive jig of the present invention is formed into a shape to surround the wire, and with the axial direction of the electric wire housing a pair of magnetic bodies divided into two parts, a pair of housing portions having an open face ,
On one side wall where a notch for inserting the electric wire is formed in the storage part, the electric wire fixing part extended outward of the storage part along the electric wire,
It becomes a closed state by matching the opening surfaces of the pair of storage parts,
In a holder configured to be in an open state by separating the opening surfaces,
A holding piece and a holding piece engaging portion are provided on the other side wall located on the opposite side of the one side wall in which the wire fixing portion is extended in the storage portion, and the opening surfaces of the pair of storage portions are When assembled, the holding piece of one storage portion is against the holding piece engaging portion of the other storage portion, and the holding piece of the other storage portion is against the holding piece engaging portion of one storage portion. , And are configured to maintain the closed state by engaging each other,
The holding piece engaging portion is configured to come into contact with three sides of the holding piece when engaged with the holding piece, and two of the three sides are inserted into the holding piece engaging portion. The holding piece (22) is on both sides in the direction perpendicular to both the insertion direction and the insertion direction of the electric wire, and the other one is opposite to the electric wire fixing portion with the holding piece in the insertion direction of the electric wire. It is characterized by being side .

更に、本発明の保持具において、前記保持片は、前記一方の側壁および他方の側壁の双方に備えられていてもよい。 Further, the coercive jig of the present invention, the holding pieces, the may be provided on both the one side wall and the other side wall.

本発明の保持具によれば、一対の収納部内に収納される磁性体(の接合面)同士が離れることがなく、分割された磁性体同士で磁気的な閉磁路が常時形成・維持されるため、雑音吸収効果が確実に得られる。   According to the holder of the present invention, the magnetic bodies (joint surfaces) housed in the pair of housing portions are not separated from each other, and a magnetic closed magnetic path is constantly formed and maintained between the divided magnetic bodies. Therefore, the noise absorption effect can be obtained with certainty.

また、本発明の保持具において、保持片が一方の側壁および他方の側壁の双方に備えられる場合には、磁性体(の接合面)同士が離れること防止する保持片が複数あるため、より確実に雑音吸収効果が得られる。 Furthermore, because the holder of the present invention, the holding piece when provided in both the one side wall and the other side wall, the retaining piece to prevent the magnetic body to each other (bonding surface) of leaves were are multiple Oh, A noise absorption effect can be obtained more reliably.

次に、本発明の実施形態について一例を挙げて図面と共に説明する。
本実施形態の吸収具１は、図１に示すように、一対の収納部１１，１２と、それら収納部１１，１２夫々に収納される一対のフェライト３０(磁性体)と、からなるものである。そして、前記吸収具１内に電線Ｗを配置する(図１(ａ)参照)ことで、該電線Ｗを伝わる雑音（ノイズ電流）の伝播を抑制する(雑音吸収効果を得る)ものである。なお図１において、図面左下を前、図面右上を後とする。また、この図１(ａ)では、電線Ｗが前後方向に沿って吸収具１内に配置されている。そして前記収納部１１，１２からなる構成は合成樹脂により一体形成されている。 Next, an exemplary embodiment of the present invention will be described with reference to an example.
As shown in FIG. 1, the absorber 1 of the present embodiment includes a pair of storage portions 11 and 12 and a pair of ferrites 30 (magnetic bodies) stored in the storage portions 11 and 12. is there. And by arrange | positioning the electric wire W in the said absorber 1 (refer Fig.1 (a)), propagation of the noise (noise current) which propagates this electric wire W is suppressed (a noise absorption effect is acquired). In FIG. 1, the lower left of the drawing is the front and the upper right of the drawing is the rear. Moreover, in this Fig.1 (a), the electric wire W is arrange | positioned in the absorber 1 along the front-back direction. And the structure which consists of the said accommodating parts 11 and 12 is integrally formed by the synthetic resin.

前記収納部１１と１２とは、その構成が同一であるので、一方の収納部１１を用いて説明する。前記収納部１１からフェライト３０を取り外した状態を図２に示す。
前記収納部１１は、中空の円柱を軸方向に二分割した形状であって、上側に開口面を有しており、その開口面からフェライト３０が出し入れ可能となっている。 Since the storage units 11 and 12 have the same configuration, description will be made using one storage unit 11. FIG. 2 shows a state where the ferrite 30 is removed from the storage portion 11.
The storage portion 11 has a shape in which a hollow cylinder is divided into two in the axial direction, and has an opening surface on the upper side, and the ferrite 30 can be taken in and out from the opening surface.

前記収納部１１の底面には、フェライト３０を上方向に付勢する付勢片１６が、収納部１１の内側に突出するように形成されている。
この収納部１１は、基本的にその周面を形成する周壁１３と、前後に夫々設けられる側壁１４ａ、１４ｂとから構成されている。
そして前記周壁１３には、収納部１１の内側に向けて突出する一対の突起部１５,１５が形成されている。また前記周壁１３の両端辺の略中央には、夫々収納部１１の外側に向けて突出する突起状の係合部１７と、この係合部１７が係合可能な被係合部１８が形成されている。 On the bottom surface of the storage portion 11, a biasing piece 16 that biases the ferrite 30 upward is formed so as to protrude inside the storage portion 11.
The storage portion 11 basically includes a peripheral wall 13 that forms the peripheral surface thereof, and side walls 14a and 14b that are provided on the front and rear sides, respectively.
The peripheral wall 13 is formed with a pair of protrusions 15, 15 that protrude toward the inside of the storage portion 11. A projecting engagement portion 17 that protrudes toward the outside of the storage portion 11 and an engaged portion 18 that can be engaged with the engagement portion 17 are formed at substantially the center of both ends of the peripheral wall 13. Has been.

前記側壁１４ａ、１４ｂには、略半円形の切欠１９ａ，１９ｂが夫々形成されている。そして一方(側壁１４ａ側)の前記切欠１９ａの周縁中央には、前記収納部１１の外方へ延びる電線固定部２０が設けられている。
また、前記収納部１１において前記電線固定部２０が延設された一方の側壁１４ａと、その反対側の他方の側壁１４ｂには、夫々上方に延在する保持片２２が設けられている。
そして、前記保持片２２の側方には、収納部１１と収納部１２とが係合して吸収具１を形成した際に、該収納部１２の保持片２２が係合する保持片係合部２４が設けられている。 The side walls 14a and 14b are formed with substantially semicircular cutouts 19a and 19b, respectively. And the electric wire fixing | fixed part 20 extended to the outward of the said accommodating part 11 is provided in the peripheral center of the said notch 19a of the one (side wall 14a side).
In addition, holding pieces 22 extending upward are provided on one side wall 14a in which the electric wire fixing portion 20 is extended in the storage portion 11 and the other side wall 14b on the opposite side.
Then, on the side of the holding piece 22, the holding piece engagement with which the holding piece 22 of the storage portion 12 is engaged when the storage portion 11 and the storage portion 12 are engaged to form the absorber 1. A portion 24 is provided.

フェライト３０は、図３に示すように、軸方向に長さを有する環状体（即ち、筒状体）を軸方向に二分割してなる形状を有している。フェライト３０の中央部には、断面半円形の電線挿通溝３１が軸方向（図中の右上−左下の前後方向）に沿って形成されており、その両側には接合面３２が形成されている。
また、フェライト３０の左右両外側面には、軸方向（図中前後方向）に沿って、前述した突起部１５,１５と係合する係合溝３４,３４が形成されている。
なお、前記収納部１１，１２にはフェライト３０として同じものが収納される。 As shown in FIG. 3, the ferrite 30 has a shape obtained by dividing an annular body (that is, a cylindrical body) having a length in the axial direction into two in the axial direction. A wire insertion groove 31 having a semicircular cross section is formed in the central portion of the ferrite 30 along the axial direction (upper and lower left and right in the figure), and joint surfaces 32 are formed on both sides thereof. .
Engaging grooves 34 and 34 that engage with the protrusions 15 and 15 described above are formed in the left and right outer surfaces of the ferrite 30 along the axial direction (the front-rear direction in the figure).
In the storage units 11 and 12, the same ferrite 30 is stored.

前述した構成を有する吸収具１を前後方向からみた側面図を図４(ａ)、(ｂ)に示す。この吸収具１は、図４(ａ)に示す如く、開口面同士を離すことで開いた状態(開放状態)となって、フェライト３０の出し入れが可能となる。また、フェライト３０の係合溝３４,３４に突起部１５,１５とが係合(図示せず)しており、フェライト３０が容易に収納部１１，１２から抜け落ちることを抑制している。なお、この状態ではフェライト３０同士は接合しておらず、環状体を形成していない。   The side view which looked at the absorber 1 which has the structure mentioned above from the front-back direction is shown to Fig.4 (a), (b). As shown in FIG. 4A, the absorber 1 is opened (opened) by separating the opening surfaces, and the ferrite 30 can be taken in and out. Further, the protrusions 15 and 15 are engaged (not shown) with the engaging grooves 34 and 34 of the ferrite 30, thereby preventing the ferrite 30 from easily falling out of the storage portions 11 and 12. In this state, the ferrites 30 are not joined to each other and an annular body is not formed.

一方、図４（ｂ）に示すように、収納部１１，１２の開口面同士を合わせることで閉じた状態となって、収納するフェライト３０の出し入れが不能となる。このとき、前記収納部１１の係合部１７と被係合部１８とは、収納部１２の被係合部１８と係合部１７とは夫々係合しており、それにより吸収具１が閉じた状態が維持される。
また同時に、前記収納部１１の保持片２２は、収納部１２の保持片係合部２４に対して、該収納部１２のの保持片２２は、収納部１１の保持片係合部２４に対して、夫々係合し合う。 On the other hand, as shown in FIG. 4 (b), the opening portions of the storage portions 11 and 12 are brought into a closed state, and the ferrite 30 to be stored cannot be taken in and out. At this time, the engaging part 17 and the engaged part 18 of the storage part 11 are engaged with the engaged part 18 and the engaging part 17 of the storage part 12, respectively. The closed state is maintained.
At the same time, the holding piece 22 of the storage portion 11 is in relation to the holding piece engaging portion 24 of the storage portion 12, and the holding piece 22 of the storage portion 12 is in relation to the holding piece engaging portion 24 of the storage portion 11. And engage each other.

この吸収具１が閉じた状態(閉成状態)において、フェライト３０は、接合面３２同士が接合して環状体を形成する。この環状体の貫通孔、即ち２つの電線挿通溝３１に囲まれた領域が、電線Ｗを挿通するための挿通孔４０となる。なお、フェライト３０は付勢片１６により各収納部１１，１２の開口面方向に付勢されているため、フェライト３０同士は、その接合面３２同士が確実に接合する。   In a state where the absorber 1 is closed (closed state), the ferrite 30 joins the joint surfaces 32 to form an annular body. A through hole of the annular body, that is, a region surrounded by the two electric wire insertion grooves 31 serves as an insertion hole 40 for inserting the electric wire W. In addition, since the ferrite 30 is urged | biased by the urging | biasing piece 16 in the opening surface direction of each accommodating part 11 and 12, the ferrite 30 mutually joins the joining surfaces 32 reliably.

また、前記収納部１１，１２の夫々の切欠１９ａ，１９ｂは、フェライト３０の電線挿通溝３１に沿った位置となっているため、吸収具１を閉じても挿通孔４０が塞がれることはない。   Moreover, since the notches 19a and 19b of the storage portions 11 and 12 are positioned along the wire insertion groove 31 of the ferrite 30, the insertion hole 40 is not blocked even when the absorber 1 is closed. Absent.

そして開放状態にある吸収具１の前記収納部１１，１２の電線挿通溝３１に対して電線Ｗを配置して、閉成状態とすることで、吸収具１に電線Ｗが配置される。その後、前記電線Ｗと、吸収具１とを強固に固定するために、図５に示す如く、該電線Ｗを前記収納部１１の電線固定部２０と、収納部１２の電線固定部２０とで挟持し、これを、例えば束線バンドＢで緊縛する。なお、図５、後述する図７および図８においては、図面右側が前、図面左側が後となっている。   And the electric wire W is arrange | positioned at the absorber 1 by arrange | positioning the electric wire W with respect to the electric wire penetration groove | channel 31 of the said accommodating parts 11 and 12 of the absorber 1 in an open state, and making it a closed state. Thereafter, in order to firmly fix the electric wire W and the absorber 1, the electric wire W is connected to the electric wire fixing portion 20 of the storage portion 11 and the electric wire fixing portion 20 of the storage portion 12 as shown in FIG. 5. This is clamped and bound with, for example, a bundle band B. In FIG. 5 and FIGS. 7 and 8 described later, the right side of the drawing is the front and the left side of the drawing is the rear.

このとき、前記電線Ｗの硬度、弾性等によって、前記電線固定部２０が電線Ｗに対して食い込む等して、前記収納部１１の電線固定部２０と、収納部１２の電線固定部２０とが電線Ｗの径以上に接近する状態となる。この場合、前記電線固定部２０が設けられる一方の切欠１９ａ側の反対側である他方の切欠１９ｂ側では、収納部１１と収納部１２とが離間する力が働く。   At this time, due to the hardness, elasticity, etc. of the electric wire W, the electric wire fixing portion 20 bites into the electric wire W, so that the electric wire fixing portion 20 of the storage portion 11 and the electric wire fixing portion 20 of the storage portion 12 become. It will be in the state which approaches the diameter of the electric wire W or more. In this case, a force that separates the storage portion 11 and the storage portion 12 acts on the other notch 19b side, which is the opposite side to the one notch 19a side where the wire fixing portion 20 is provided.

しかし、前記電線固定部２０が設けられる一方の側壁１４ａの反対側に位置する他方の側壁１４ｂには、保持片２２および保持片係合部２４が設けられているため、前記収納部１１と収納部１２との離間が防止され、一対の収納部１１、１２の開口面同士が合わされて閉じた状態が保持される。その結果、一対の収納部１１、１２内に収納されるフェライト３０(の接合面３２)同士が離れることがなく、分割されたフェライト３０同士で磁気的な閉磁路が常時形成・維持されるため、雑音吸収効果が確実に得られる。   However, since the holding piece 22 and the holding piece engaging portion 24 are provided on the other side wall 14b located on the opposite side of the one side wall 14a on which the electric wire fixing portion 20 is provided, Separation from the portion 12 is prevented, and the closed surfaces of the pair of storage portions 11 and 12 are held together. As a result, the ferrites 30 (joint surfaces 32) housed in the pair of housing parts 11 and 12 are not separated from each other, and a magnetic closed magnetic circuit is constantly formed and maintained between the divided ferrites 30. The noise absorption effect can be reliably obtained.

（別の実施例）
上述の実施例では、他方の側壁１４ｂにだけ保持片２２が備えられた例を挙げたが、本発明はこの実施例に限定されるものではない。例えば図６および図７に示す如く、他方の側壁１４ｂに加えて、一方の側壁１４ａに保持片２２を備えるようにしてもよい。この場合の保持具５０は、双方の側壁１４ａ,１４ｂに保持片２２,２２が備えられるため、一対の収納部１１、１２内に収納されるフェライト３０(の接合面３２)同士が離れることを、より確実に防止するため、雑音吸収効果がより確実に得られる。 (Another example)
In the above-described embodiment, the example in which the holding piece 22 is provided only on the other side wall 14b has been described. However, the present invention is not limited to this embodiment. For example, as shown in FIGS. 6 and 7, in addition to the other side wall 14b, a holding piece 22 may be provided on one side wall 14a. In this case, the holding tool 50 is provided with holding pieces 22 and 22 on both side walls 14a and 14b, so that the ferrites 30 (joint surfaces 32) housed in the pair of housing portions 11 and 12 are separated from each other. In order to prevent more reliably, the noise absorption effect can be obtained more reliably.

（更に別の実施例）
上述の別の実施例と、別の実施例では、何れも側壁に保持片が備えられた形状であるが、本発明はこれに限定されず、図８に示す如く、双方の側壁１４ａ,１４ｂに電線固定部２０,２０を延設してもよい。この保持具６０でも、一対の収納部１１、１２内に収納されるフェライト３０(の接合面３２)同士が離れることが好適に防止されるので、雑音吸収効果を確実に得られる。 (Still another embodiment)
In the above-described another embodiment and another embodiment, the side wall is provided with a holding piece. However, the present invention is not limited to this, and as shown in FIG. 8, both side walls 14a and 14b are formed. The wire fixing portions 20 and 20 may be extended to each other. Also in this holder 60, since the ferrite 30 (joint surface 32) accommodated in a pair of accommodating parts 11 and 12 is prevented suitably, the noise absorption effect is obtained reliably.

なお、上述の更に別の実施例に場合、一対の収納部１１,１２から外方へ延在する電線固定部２０,２０が、側壁１４ａ,１４ｂ側の両方に設けられる。そのため、実施例の保持具１や、別の実施例の保持具５０に比較して、電線Ｗがより長い部分で動きを規制される。そのため、狭い場所への配置が求められる場合には、該保持具１、保持具５０の方が好適である。   In the case of the above-described further embodiment, the wire fixing portions 20 and 20 extending outward from the pair of storage portions 11 and 12 are provided on both the side walls 14a and 14b. Therefore, compared with the holder 1 of an Example and the holder 50 of another Example, a motion is controlled by the part where the electric wire W is longer. Therefore, the holder 1 and the holder 50 are more suitable when arrangement in a narrow place is required.

（変更例）
(１)上記実施例では、電線固定部２０は切欠の周縁中央に設けられている。しかし、本発明はこれに限定されず、電線固定部２０は、切欠の周縁中央から左右方向に移動した適宜移動した位置に設けるようにしてもよい。このようにすることで一対の収納部１１,１２を係合させて吸収具が閉じた状態がされる際に、係合部１７・被係合部１８と、電線固定部２０,２０との位置関係を変えることが可能となる。このため、保持具が使用される状況、スペース等に合わせて前述の位置関係を変えることで、電線Ｗを確実に保持具に対して固定すると共に、一対の収納部１１,１２の係合を好適になし得るように構成できる。
(２)上記実施例では、フェライト３０に挿通させて雑音吸収効果を得る対象物として電線が挙げられているが、本発明はこれに限定されるものではなく、電気・信号を流すもの等であって、雑音（ノイズ電流）の伝播が考えられるもの全てに適応可能である。 (Example of change)
(1) In the said Example, the electric wire fixing | fixed part 20 is provided in the peripheral center of a notch.
