Description

本発明は、電線のシールド構造、具体的には、複数の電線を１つのシールド材で一括して包囲するシールド構造に関する。   The present invention relates to a shield structure for electric wires, and specifically to a shield structure in which a plurality of electric wires are collectively surrounded by one shield material.

例えば、自動車等の車両において電装品間を電線で接続する場合、該電装品から生ずる電磁波等のノイズの伝播を防ぐため、電線をシールド材（編組や箔等）で被覆している。かかるシールド材の端部にはシールドシェルが組み付けられており、該シールドシェルを電装品の筺体や車体板金パネルなどに接触させることで、ノイズをアースさせている。その際、複数の電線を１つのシールド材で一括して包囲し、その端部に単一のシールドシェルを組み付けることで、シールドシェルの組付工数を削減することができる（特許文献１参照）。   For example, when electrical components are connected with electric wires in a vehicle such as an automobile, the electric wires are covered with a shielding material (such as a braid or foil) in order to prevent the propagation of noise such as electromagnetic waves generated from the electric components. A shield shell is assembled to the end of the shield material, and noise is grounded by bringing the shield shell into contact with a housing of an electrical component or a body sheet metal panel. At that time, by assembling a plurality of electric wires together with one shield material and assembling a single shield shell at the end thereof, the number of man-hours for assembling the shield shell can be reduced (see Patent Document 1). .

しかしながら、このようなシールド構造であっても、特定周波数のノイズを遮断し、かかるノイズの伝播を防止することは難しい。また、複数の電線を１つのシールド材で一括して包囲した場合、これらの電線束が振動によって振れてシールド材が該シールド材の外装部材（プロテクタ）や車体板金などに当たった際の衝撃が大きくなり、電線及びシールド材の損傷、異音などを生じさせるおそれがある。   However, even with such a shield structure, it is difficult to block noise at a specific frequency and prevent propagation of such noise. In addition, when a plurality of electric wires are collectively surrounded by a single shielding material, the electric wire bundle is shaken by vibration, and the impact when the shielding material hits the exterior member (protector) of the shielding material or the body sheet metal is affected. There is a risk that the electric wire and the shield material may be damaged or abnormal noise may be generated.

本発明はこれを踏まえてなされたものであり、その解決しようとする課題は、特定周波数のノイズの伝播を防止するとともに、電線及びシールド材の損傷、異音の発生を防止することが可能な電線のシールド構造を提供することにある。   The present invention has been made based on this, and the problem to be solved is that it is possible to prevent the propagation of noise of a specific frequency and to prevent the damage of the electric wire and the shield material and the generation of abnormal noise.

A shield shell for grounding the shield material at the cylindrical end, and an outer periphery of the intermediate portion of the shield material, the bundle of the shield material and the plurality of electric wires being held together and holding the shield material in the middle And an earth metal fitting for earthing at the portion.

この場合、前記アース金具は、前記シールド材の外周に沿って移動可能に形成することが好ましい。   In this case, it is preferable that the earth metal fitting is formed to be movable along the outer periphery of the shield material.

本発明によれば、特定周波数のノイズの伝播を防止するとともに、電線及びシールド材の損傷、異音の発生を防止することが可能な電線のシールド構造を実現することができる。   ADVANTAGE OF THE INVENTION According to this invention, while preventing the propagation | transmission of the noise of a specific frequency, the electric wire shield structure which can prevent generation | occurrence | production of damage and an abnormal noise of an electric wire and a shielding material is realizable.

本発明の一実施形態に係る電線のシールド構造の全体構成を示す平面面である。It is a plane surface which shows the whole structure of the shield structure of the electric wire which concerns on one Embodiment of this invention. 図１に示すアース金具の配置とした場合に形成されるシールド回路を模式的に示す図である。It is a figure which shows typically the shield circuit formed when it is set as arrangement | positioning of the earth metal fitting shown in FIG. アース金具の取付位置を変更して図１に示す配置とは別配置とした場合に形成されるシールド回路を模式的に示す図である。It is a figure which shows typically the shield circuit formed when the attachment position of a grounding metal is changed and it is set as the arrangement different from the arrangement shown in FIG.

以下、本発明の電線のシールド構造（以下、単にシールド構造ともいう。）について、添付図面を参照して説明する。かかるシールド構造は、車両に配線される複数の電線を１つのシールド材で包囲してシールドするためのものである。各電線は、芯線である導体の外周が絶縁被覆で被覆された構成となっており、複数本が束ねられて自動車等の車両に搭載された比較的高圧の電装品間、例えば、ハイブリッド自動車に搭載された電動モータのインバータと電源装置との間などに配線される。なお、電線は、２層以上の導体と絶縁被覆が同心状に配された構造とすることも可能である。   Hereinafter, a shield structure for electric wires according to the present invention (hereinafter also simply referred to as a shield structure) will be described with reference to the accompanying drawings. Such a shield structure is for surrounding and shielding a plurality of electric wires wired to a vehicle with one shield material. Each electric wire has a configuration in which the outer periphery of a conductor that is a core wire is covered with an insulating coating, and a plurality of wires are bundled and mounted between relatively high-voltage electrical components mounted on a vehicle such as an automobile, for example, a hybrid vehicle. It is wired between the inverter of the mounted electric motor and the power supply device. The electric wire may have a structure in which two or more layers of conductors and an insulating coating are arranged concentrically.

図１は、本発明の一実施形態に係る電線のシールド構造の全体構成を示す平面図である。なお、図１には、２本の電線１をシールドするためのシールド構造を一例として示しているが、電線の本数は特に限定されず、３本以上であっても構わない。これらの電線１には、伸延方向（図１においては、左右方向）の双方の端末部に各線共有のコネクタ２が１つずつ設けられている。そして、各電線１には、端末部の絶縁被覆を剥離して露出させた導体にコネクタ２の接続端子２１が取り付けられている。かかる接続端子２１が電装品側に設けられた接続端子（図示しない）と接続されることで、電線１は該電装品と導通される。なお、コネクタ２は、接続端子２１を収容するハウジング２２を備えており、ハウジング２２は、電線１の端末部に取り付けられた接続端子２１を外部（電装品側）へ臨ませた状態で収容可能な構成となっている。   FIG. 1 is a plan view showing an overall configuration of a shield structure for an electric wire according to an embodiment of the present invention. In addition, in FIG. 1, although the shield structure for shielding the two electric wires 1 is shown as an example, the number of electric wires is not specifically limited, Three or more may be sufficient. Each of these electric wires 1 is provided with one connector 2 for sharing each line at both end portions in the extending direction (left and right direction in FIG. 1). And in each electric wire 1, the connection terminal 21 of the connector 2 is attached to the conductor which peeled and exposed the insulation coating of the terminal part. By connecting the connection terminal 21 to a connection terminal (not shown) provided on the electrical component side, the electric wire 1 is electrically connected to the electrical component. The connector 2 includes a housing 22 that accommodates the connection terminal 21, and the housing 22 can be accommodated with the connection terminal 21 attached to the terminal portion of the electric wire 1 facing the outside (electrical component side). It has become a structure.

本実施形態に係るシールド構造は、複数の電線１を一括して包囲してシールドする筒状のシールド材３と、シールド材３の筒端部３ａ,３ｂに接続されて該筒端部３ａ,３ｂでシールド材３をアース（接地）するシールドシェル４と、シールド材３の中間部の外周に取り付けられてシールド材３及び複数の電線１を束ねて保持するとともに、シールド材３を中間部でアースするアース金具５とを備えている。   The shield structure according to the present embodiment includes a cylindrical shield material 3 that collectively surrounds and shields a plurality of electric wires 1, and cylinder end portions 3a and 3b of the shield material 3 connected to the cylindrical end portions 3a and 3b. A shield shell 4 for grounding (grounding) the shield material 3 in 3b and a shield shell 3 attached to the outer periphery of the intermediate portion of the shield material 3 and holding the shield material 3 and the plurality of electric wires 1 in a bundle, and holding the shield material 3 at the intermediate portion And a grounding metal fitting 5 for grounding.

シールド材３は、編組や箔を筒状に形成してなる導体であって、コネクタ２ａ,２ｂの間で複数の電線１の外周を包囲するように配されている。一例として、図１には、編組導体をシールド材３とした構成を示す。この場合、シールド材３は、一体の筒状に形成され、全長（図１の左右方向に対する寸法）に亘って断面形状が同一（例えば、円筒状であれば、同一径）をなしている。そして、シールド材３は、筒端部３ａ,３ｂがシールドシェル４の外周に載置され、該筒端部３ａ,３ｂに被冠させた圧着リング６でシールドシェル４に圧着接続されている。なお、シールド材３は、その外周を外装部材（プロテクタ）で覆った構成としてもよい。   The shield material 3 is a conductor formed by forming a braid or a foil into a cylindrical shape, and is arranged so as to surround the outer periphery of the plurality of electric wires 1 between the connectors 2a and 2b. As an example, FIG. 1 shows a configuration in which a braided conductor is a shield material 3. In this case, the shield material 3 is formed in an integral cylindrical shape, and has the same cross-sectional shape (for example, the same diameter in the case of a cylindrical shape) over the entire length (dimension with respect to the horizontal direction in FIG. 1). The shield material 3 has cylinder end portions 3a and 3b placed on the outer periphery of the shield shell 4, and is crimped and connected to the shield shell 4 by a crimp ring 6 covered by the tube end portions 3a and 3b. In addition, the shielding material 3 is good also as a structure which covered the outer periphery with the exterior member (protector).

シールドシェル４は、圧着リング６を被冠させてシールド材３を接続する筒状の接続部４１と、接続部４１から外側へ板状に延在するように設けられたシェル固定部４２を有して構成されている。接続部４１は、コネクタ２のハウジング２２の外側を包囲するように形成され、ハウジング２２に組み付けられている。シェル固定部４２は、電装品の筺体や車体の板金パネル等に固定（例えば、ボルトで締結固定）可能に構成されている。これにより、シールドシェル４は、シェル固定部４２を電装品の筺体や車体の板金パネル等に接触させることで、該シェル固定部４２を通してシールド材３を筒端部３ａ,３ｂでアース（接地）させることができる。   The shield shell 4 includes a cylindrical connection portion 41 that covers the crimping ring 6 and connects the shield material 3, and a shell fixing portion 42 that extends outwardly from the connection portion 41 in a plate shape. Configured. The connecting portion 41 is formed so as to surround the outside of the housing 22 of the connector 2 and is assembled to the housing 22. The shell fixing portion 42 is configured to be fixed (for example, fastened and fixed with bolts) to a housing of an electrical component, a sheet metal panel of a vehicle body, or the like. As a result, the shield shell 4 contacts the shell fixing portion 42 with the housing of the electrical component, the sheet metal panel of the vehicle body, and the like, so that the shield material 3 is grounded (grounded) at the cylindrical end portions 3a and 3b through the shell fixing portion 42. Can be made.

アース金具５は、シールド材３の外周に接触する筒状の金具締付部（以下、締付部という。）５１と、車体の板金パネル等に固定される金具固定部（同、固定部という。）５２を有して構成されている。例えば、アース金具５は、導電性を有する金属製のバンドやクランプなどとして構成することが可能である。一例として、導線性を有する帯状の金属板を締付部５１とし、固定部５２には、該締付部５１を挿入して係止させる貫通孔を形成してなるバンドをアース金具５として適用することができる。この場合、締付部５１を固定部５２の一方側から突設し、シールド材３の外周に巻いた締付部５１を固定部５２の貫通孔へ他方側から挿入して一方側へ引き出す構成とすればよい。そして、固定部５２の貫通孔の内面に係合爪を設け、締付部５１の表面に鋸歯状の被係合溝を形成し、固定部５２の係合爪を締付部５１の被係合溝に係合させることで、アース金具５をシールド材３の外周に締め付ける構成とすればよい。また、別の一例として、導電性を有する金属板を折り曲げ加工して、折曲部分に締付部５１を形成し、金属板の両端部分を重畳可能に形成して固定部５２としたクランプをアース金具５として適用することもできる。かかるアース金具５によれば、固定部５２を重畳させるように弾性変形させることで、締付部５１が縮小するように弾性変形し、該締付部５１をシールド材３の外周に接触させた状態で締め付ける構成とすることができる。なお、アース金具５をバンドもしくはクランプのいずれとした場合であっても、固定部５２には、アース金具５を車体の板金パネル等へ固定するボルトを挿通するためのボルト孔５３が形成されている。   The ground metal fitting 5 includes a cylindrical metal fitting fastening portion (hereinafter referred to as a fastening portion) 51 that contacts the outer periphery of the shield material 3 and a metal fitting fixing portion (referred to as a fixing portion) that is fixed to a sheet metal panel of the vehicle body. .) 52 is configured. For example, the ground metal fitting 5 can be configured as a conductive metal band or clamp. As an example, a band-shaped metal plate having a conductive property is used as the fastening part 51, and a band formed by forming a through hole in which the fastening part 51 is inserted and locked is applied to the fixing part 52 as the ground metal fitting 5. can do. In this case, the tightening portion 51 protrudes from one side of the fixing portion 52, and the tightening portion 51 wound around the outer periphery of the shield material 3 is inserted into the through hole of the fixing portion 52 from the other side and pulled out to the one side. And it is sufficient. Then, an engaging claw is provided on the inner surface of the through hole of the fixing portion 52, a serrated engagement groove is formed on the surface of the fastening portion 51, and the engaging claw of the fixing portion 52 is engaged with the fastening portion 51. What is necessary is just to set it as the structure which fastens the earth | ground metal fitting 5 to the outer periphery of the shielding material 3 by engaging with a joint groove. Further, as another example, a metal plate having conductivity is bent to form a tightening portion 51 at the bent portion, and both ends of the metal plate are formed so as to be superposed so as to be a fixed portion 52. It can also be applied as the ground metal fitting 5. According to the ground metal fitting 5, the fastening portion 52 is elastically deformed so as to overlap, so that the fastening portion 51 is elastically deformed so as to be reduced, and the fastening portion 51 is brought into contact with the outer periphery of the shield material 3. It can be set as the structure tightened in a state. Whether the ground metal fitting 5 is a band or a clamp, the fixing portion 52 is formed with a bolt hole 53 for inserting a bolt for fixing the ground metal fitting 5 to a sheet metal panel or the like of the vehicle body. Yes.

したがって、アース金具５をシールド材３の外周に取り付ける場合、バンドであれば、締付部５１をシールド材３の外周に巻き付け、該締付部５１を固定部５２の貫通孔に挿入して係合させる。また、クランプであれば、固定部５２が開いた状態で締付部５１をシールド材３に装着し、固定部５２が重畳するようにアース金具５を弾性変形させる。これにより、締付部５１を縮小させてシールド材３の外周を締め付けた状態とすればよい。そして、ボルト孔５３に挿通したボルトを車体の板金パネル等に締結することで、締付部５１がシールド材３の外周を締め付けた状態でアース金具５を該板金パネル等に固定することができる。これにより、アース金具５は、固定部５２を車体の板金パネル等に接触させることで、該固定部５２を通してシールド材３を中間部（シールドシェル４ａとシールドシェル４ｂの間）でアース（接地）させることができる。   Therefore, when attaching the grounding metal fitting 5 to the outer periphery of the shield member 3, if it is a band, the tightening portion 51 is wound around the outer periphery of the shield member 3, and the tightening portion 51 is inserted into the through hole of the fixing portion 52. Combine. In the case of a clamp, the fastening portion 51 is attached to the shield material 3 with the fixing portion 52 open, and the grounding metal 5 is elastically deformed so that the fixing portion 52 overlaps. Accordingly, the tightening portion 51 may be reduced to a state where the outer periphery of the shield material 3 is tightened. Then, by fastening the bolt inserted through the bolt hole 53 to a sheet metal panel or the like of the vehicle body, the grounding metal 5 can be fixed to the sheet metal panel or the like with the tightening portion 51 tightening the outer periphery of the shield material 3. . As a result, the grounding metal 5 is brought into contact with the sheet metal panel or the like of the vehicle body so that the shield member 3 is grounded (grounded) at the intermediate part (between the shield shell 4a and the shield shell 4b) through the fixed part 52. Can be made.

一方で、締付部５１と固定部５２との係合を解くこと、あるいは、固定部５２を重畳させた状態から開いた状態とすることで、締付部５１を拡張させることができる。したがって、この状態においては、アース金具５をシールド材３の外周に沿って移動させることができる。すなわち、シールド材３に対するアース金具５の取付位置を容易に変更することができる。取付位置の変更後は、締付部５１を縮小させてシールド材３の外周を締め付けた状態で、アース金具５を改めて車体の板金パネル等にボルトで締結固定すればよい。   On the other hand, the fastening part 51 can be expanded by releasing the engagement between the fastening part 51 and the fixing part 52 or by opening the fixing part 52 from the overlapped state. Therefore, in this state, the ground metal fitting 5 can be moved along the outer periphery of the shield material 3. That is, the mounting position of the grounding metal 5 with respect to the shield material 3 can be easily changed. After changing the mounting position, the grounding metal 5 may be fastened and fixed to the sheet metal panel or the like of the vehicle body with bolts in a state where the tightening portion 51 is reduced and the outer periphery of the shield material 3 is tightened.

また、締付部５１を締め付けた状態においては、シールド材３で一括して包囲された複数の電線１をシールド材３とともに束ねることができ、アース金具５は、これらのシールド材３及び複数の電線１を束ねた状態で保持することができる。したがって、ボルト孔５３に挿通したボルトで固定部５２を車体の板金パネル等へ締結固定することで、アース金具５は、シールド材３及び複数の電線１を束ねて保持した状態で、これらを車体の板金パネル等へ固定することができる。これにより、車両が振動した場合であっても、電線１の束が振れることを抑制することができる。この結果、シールド材３がその外装部材（プロテクタ）や車体の板金パネル等に当たることを防止することができ、電線１及びシールド材３の損傷や異音の発生を防止することができる。   Further, in a state where the tightening portion 51 is tightened, the plurality of electric wires 1 collectively surrounded by the shield material 3 can be bundled together with the shield material 3. The electric wire 1 can be held in a bundled state. Accordingly, the fixing member 52 is fastened and fixed to the sheet metal panel or the like of the vehicle body with the bolts inserted through the bolt holes 53, so that the ground metal fitting 5 holds the shield material 3 and the plurality of electric wires 1 in a bundled state. It can be fixed to a sheet metal panel. Thereby, even if it is a case where a vehicle vibrates, it can suppress that the bundle | flux of the electric wire 1 shakes. As a result, it is possible to prevent the shield material 3 from hitting the exterior member (protector), the sheet metal panel of the vehicle body, and the like, and it is possible to prevent the electric wire 1 and the shield material 3 from being damaged and the generation of abnormal noise.

ここで、図１には、２つのアース金具５をシールド材３の中間部（シールドシェル４ａとシールドシェル４ｂの間）に略等間隔で配置した構成を一例として示している。なお、シールド材３に取り付けるアース金具５の数は、任意に設定することができ、１つのみでもよいし、３つ以上であっても構わない。図１に示すように、２つのアース金具５を配置した場合、これらのアース金具５の間、及び各アース金具５とシールドシェル４との間にそれぞれシールド回路を形成することができる。図２には、図１に示すようなアース金具５の配置とした場合に形成されるシールド回路を模式的に示す。この場合、シールドシェル４ａとアース金具５ａとの間にシールド回路Ｃ２１、アース金具５ａとアース金具５ｂの間にシールド回路Ｃ２２、シールドシェル４ｂとアース金具５ｂとの間にシールド回路Ｃ２３がそれぞれ形成される。   Here, FIG. 1 shows, as an example, a configuration in which two ground metal fittings 5 are arranged at substantially equal intervals in the middle portion of the shield material 3 (between the shield shell 4a and the shield shell 4b). In addition, the number of the earth metal fittings 5 attached to the shield material 3 can be set arbitrarily, and only one may be sufficient and three or more may be sufficient. As shown in FIG. 1, when two ground metal fittings 5 are arranged, shield circuits can be formed between these ground metal fittings 5 and between each earth metal fitting 5 and the shield shell 4. FIG. 2 schematically shows a shield circuit formed when the ground metal fitting 5 is arranged as shown in FIG. In this case, a shield circuit C21 is formed between the shield shell 4a and the ground metal 5a, a shield circuit C22 is formed between the ground metal 5a and the ground metal 5b, and a shield circuit C23 is formed between the shield shell 4b and the ground metal 5b. The

また、上述したように、アース金具５は、シールド材３の外周に沿って移動させることができ、容易に取付位置を変更することができる。したがって、例えば、図３に示すように、２つのアース金具５をそれぞれシールドシェル４の近傍に位置付け、２つのアース金具５の間隔を広げた配置とすることも可能である。この場合、シールドシェル４ａとアース金具５ａとの間にシールド回路Ｃ３１、アース金具５ａとアース金具５ｂの間にシールド回路Ｃ３２、シールドシェル４ｂとアース金具５ｂとの間にシールド回路Ｃ３３がそれぞれ形成される。   Moreover, as above-mentioned, the earth metal fitting 5 can be moved along the outer periphery of the shielding material 3, and can change an attachment position easily. Therefore, for example, as shown in FIG. 3, it is possible to position the two ground metal fittings 5 in the vicinity of the shield shell 4 and to increase the distance between the two ground metal fittings 5. In this case, a shield circuit C31 is formed between the shield shell 4a and the ground metal 5a, a shield circuit C32 is formed between the ground metal 5a and the ground metal 5b, and a shield circuit C33 is formed between the shield shell 4b and the ground metal 5b. The

図２及び図３に示すように、アース金具５の取付位置を変更することで、かかるアース金具５及びシールドシェル４によって形成されるシールド回路の大きさを変更させることができる。例えば、シールド回路Ｃ２２は、シールド回路Ｃ２１,Ｃ２３よりも小さく、シールド回路Ｃ３２は、シールド回路Ｃ３１,Ｃ３３よりも大きい。また、シールド回路Ｃ２２は、シールド回路Ｃ３１,Ｃ３２,Ｃ３３のいずれよりも小さい。このようにシールド回路の大きさを変更させることで、アース金具５及びシールドシェル４でシールド可能な周波数域を変更させることができる。したがって、アース金具５の取付位置を調整することで、電線１が接続される電装品から生ずる電磁波等の特定周波数のノイズを遮断し、かかるノイズの伝播を防止することが可能となる。   As shown in FIGS. 2 and 3, the size of the shield circuit formed by the earth metal fitting 5 and the shield shell 4 can be changed by changing the mounting position of the earth metal fitting 5. For example, the shield circuit C22 is smaller than the shield circuits C21 and C23, and the shield circuit C32 is larger than the shield circuits C31 and C33. The shield circuit C22 is smaller than any of the shield circuits C31, C32, and C33. Thus, by changing the size of the shield circuit, the frequency range that can be shielded by the ground metal fitting 5 and the shield shell 4 can be changed. Therefore, by adjusting the mounting position of the ground metal 5, it is possible to block noise of a specific frequency such as electromagnetic waves generated from the electrical component to which the electric wire 1 is connected and to prevent propagation of such noise.
