Shielding structure for wire harness

A shielding structure for a wire harness includes a seal member which has a wire through hole that allows the wire to pass therethrough while sealing a circumference of the wire. The wire has a structure where an insulating resin layer is formed on an outer circumference of a conductor, and a predetermined range in a length direction of the conductor is coated with a shield layer formed by resin plating to cover an outer circumferential surface of the insulating resin layer. A terminal portion of the wire is passed through the wire through hole of the seal member to be introduced into the shield wall to a position where the shield layer exists, whereby an inner circumference of the wire through hole is made in close contact with the shield layer to cause the shield layer and the seal member to be electrically conducted with each other.

TECHNICAL FIELD

The present invention relates to a shielding structure in the case where a wire harness is to be introduced into a shield case.

BACKGROUND ART

Conventionally, in the case where terminal portions of wires are to be introduced into a shield case while being shielded, for example, a shield shell120is disposed so as to surround connectors110disposed on the terminal portions of the wires as shown inFIGS. 13 to 15, a rear end portion of the shield shell120is doubly covered by an end portion of a braid121which is disposed so as to cover the wires, and the covered portion is crimped and fixed by a ring123. In this state, a front surface portion of the shield shell120is fixed to a shield case101in a conduction state, and terminals112of the connectors110which are introduced into the shield case101are connected to a terminal block102of the shield case101. In this case, it is usual to interpose a seal packing122between the matching surfaces of the shield case101and the shield shell120, thereby ensuring the sealing property between the shield case101and the shield shell120.

The structure in which shielding is performed as described above is well known in, for example, Patent Document 1 and the like.

SUMMARY OF INVENTION

Technical Problem

In a conventional shielding structure such as that shownFIGS. 13 to 15, components such as the shield shell120, the braid121, and the crimping ring123are necessary in order to perform shielding, and there is a problem in that the number of components is large.

Moreover, the entire length of a wire from one end to the other end is covered by the single braid121. In the case where the wire is to be branched along the way and connectors are to be attached to the tip ends of the branched two wires, respectively, therefore, there is also a problem in that the configuration of the braid121is so complicated that it is hardly coped with.

In the case where the packing122is interposed between the matching surfaces of the shield case101and the shield shell120, it is difficult to enable the shielding effect to sufficiently function in the range of the thickness of the packing122, and there is a possibility that a shield leakage portion may be formed.

In the portion where the end portion of the braid121covers the outer circumference of the rear end portion of the shield shell120, the density of the braid121is low, and hence a countermeasure such as that in which the end portion of the braid121is folded back to form a double structure is taken so as to prevent the shielding performance from being lowered. The process of forming the structure is cumbersome. Moreover, the portion where the braid121is folded back to form a double braid structure is excessively expanded, and an extra space is sometimes necessary in the periphery.

The invention is conducted in view of the above-discussed circumstances. It is an object of the invention to provide a shielding structure for a wire harness in which the number of components can be reduced, which, even in a situation where a wire is branched along the way, can easily cope with the situation, in which sufficient sealing and shielding performances can be ensured, and which can solve troubles that are caused when a braid is used.

Solution to Problem

The object of the invention can be attained by the following configurations.

(1) A shielding structure for a wire harness in which a wire constituting a wire harness is to be introduced into a shield wall of an electric apparatus while being shielded, comprising:

a seal member which is made of electrically conductive rubber, which has a wire through hole that allows the wire to pass therethrough while sealing a circumference of the wire, and which is to be attached to the shield wall in a closely contacted state, wherein

the wire has a structure where an insulating resin layer is formed on an outer circumference of a conductor, and a predetermined range in a length direction of the conductor is coated with a shield layer formed by resin plating to cover an outer circumferential surface of the insulating resin layer, and

a terminal portion of the wire is passed through the wire through hole of the seal member to be introduced into the shield wall to a position where the shield layer formed by the resin plating exists, whereby an inner circumference of the wire through hole of the seal member is made in close contact with the shield layer of the wire to cause the shield layer and the seal member made of electrically conductive rubber to be electrically conducted with each other.

(2) The shielding structure for a wire harness according to (1) above wherein, in the terminal portion of the wire introduced into the shield wall, a non-resin plating portion where the resin plating is excluded in a predetermined range from an end portion of the conductor is ensured, a conductor exposed portion in which the insulating resin layer is excluded is disposed in an end portion of the non-resin plating portion, and a connecting portion is disposed in the conductor exposed portion.

(3) The shielding structure for a wire harness according to (1) or (2) above wherein a plurality of the conductors are covered in a state where the conductors are insulated from each other, by a resin mold portion which is integrally molded, and which functions as the insulating resin layer, a predetermined range in a length direction of the conductors is coated with a shield layer formed by the resin plating to cover an outer circumferential surface of the resin mold portion,

the wire through hole that allows the resin mold portion to pass therethrough while sealing a circumference of the resin mold portion that integrally holds the plurality of conductors is disposed in the seal member, and

terminal portions of the conductors which are held by the resin mold portion are passed through the wire through hole of the seal member to be introduced into the shield wall to a position where the shield layer formed by the resin plating exists, whereby the inner circumference of the wire through hole of the seal member is made in close contact with the shield layer which covers the outer circumferential surface of the resin mold portion, and the shield layer and the seal member made of electrically conductive rubber are electrically conducted with each other.

(4) A shell fixture structure comprising:

a wire harness in which a circumference of a wire is covered by a shield layer;

a resin mold portion which covers a plurality of conductors in a terminal portion of the wire in a state where the conductors are insulated from each other;

a ring-like shield shell through which the resin mold portion is passed;

a wire terminal-side movement regulating portion which is formed on a side of an outer circumference of the resin mold portion; and

a shell-side movement regulating portion which is formed on a side of an inner circumference of the shield shell, wherein

the wire terminal-side movement regulating portion and the shell-side movement regulating portion are engaged with each other at a predetermined relative rotation position in a case where the both are relatively rotated about an axis in a state where the shield shell is externally inserted onto the resin mold portion, thereby regulating relative movement of the resin mold portion and the shield shell in an axial direction.

(5) The shell fixture structure according to (4) above, wherein a rotation regulating mechanism which regulates relative rotation of the resin mold portion and the shield shell at the predetermined relative rotation position is disposed between the wire terminal-side movement regulating portion and the shell-side movement regulating portion.

According to the shielding structure for a wire harness having the configuration of (1) above, the wire portion which is exposed to the outside of the shield wall is shielded by the resin plating which is used in place of a braid, and a portion of the wire introduced into the shield wall is shielded by the seal member made of electrically conductive rubber. Therefore, a braid, a shield shell, and a crimping ring are not necessary, and hence the number of components can be reduced.

Moreover, the seal member itself is electrically conductive. Unlike the case where a conventional packing is used, therefore, there is no possibility that a shield leakage portion may be formed, and shielding and sealing performances which are sufficiently high can be provided.

Moreover, resin plating is used in place of a braid. Even in a situation where the wire is branched along the way, therefore, the structure can easily cope with the situation.

Furthermore, a braid is not used, and hence a compact wire harness is obtained which is free from troubles that may be caused in the case where a braid is used, i.e., extra processing such as folding into a double braid, and necessity of an extra space.

According to the shielding structure for a wire harness having the configuration of (2) above, the non-resin plating portion is ensured in the terminal portion of the wire, the conductor exposed portion in which the insulating resin layer is excluded is disposed in the end portion of the non-resin plating portion, and the connecting portion is disposed in the conductor exposed portion. Therefore, the plating layer which is the shield layer, and the connecting portion connected to the conductor can be surely maintained in a nonconductive state.

According to the shielding structure for a wire harness having the configuration of (3) above, the plurality of conductors are covered by the resin mold portion in the state where they are insulated from each other, and the shield layer formed by the resin plating is formed so as to cover the outer circumferential surface of the resin mold portion. Therefore, the plurality of conductors can be integrally shielded while insulating them.

Moreover, the shield layer can be made conductive with the seal member by passing the resin mold portion through the wire through hole of the seal member made of electrically conductive rubber. When the seal member is attached to the shield case so as be in close contact therewith, therefore, both the sealing function and the shielding function can be simultaneously exerted.

According to the shell fixture structure having the configuration of (4) above, the resin mold portion can be passed through a through hole of the shield shell which is formed into a ring-like shape, and hence the shield shell can be externally inserted from any of the front and rear sides of the resin mold portion. When, in the state where the shield shell is externally inserted onto the resin mold portion, the both are then relatively rotated to the predetermined relative rotation position, and the wire terminal-side movement regulating portion and the shell-side movement regulating portion are engaged with each other, relative movement of the resin mold portion and the shield shell in the axial direction is regulated, and the resin mold portion is installed to the shield shell.

Therefore, the installation direction of the resin mold portion with respect to the through hole of the shield shell is not restricted. According to the configuration, the resin mold portion which is integrally molded with the terminal portion of the wire may be passed through the through hole of the shield shell from the side of the terminal portion of the wires. Unlike a conventional shell fixture structure, therefore, a work of previously passing the shield shell through the wire harness is not required.

According to the shell fixture structure having the configuration of (5) above, when, in the state where the shield shell is externally inserted onto the resin mold portion, the both are relatively rotated to the predetermined relative rotation position, and the wire terminal-side movement regulating portion and the shell-side movement regulating portion are engaged with each other to regulate relative movement in the axial direction, relative rotation of the resin mold portion and the shield shell is regulated by the rotation regulating mechanism. With respect to the resin mold portion and the shield shell, therefore, the integrally fixed state where axial movement and relative rotation about the axis are regulated is held, and the fixed state is prevented from being accidentally cancelled.

When the integrally fixed state of the resin mold portion and the shield shell is to be cancelled, a rotational moment of a certain level or higher may be applied against the engagement force of the rotation regulating mechanism, and the resin mold portion and the shield shell may be relatively rotated until the engagement of the wire terminal-side movement regulating portion and the shell-side movement regulating portion is cancelled.

DESCRIPTION OF EMBODIMENTS

First Embodiment

FIGS. 1A and 1Bare views illustrating a shielding structure for a wire harness of a first embodiment,FIG. 1Ais an exploded perspective view,FIG. 1Bis a perspective view showing an assembled state, andFIG. 2is a sectional view of a portion where an end portion of the wire harness is introduced into a shield case.

The shielding structure of the first embodiment is a structure in the case where a wire1constituting the wire harness W1is introduced into the interior51of a shield wall50of an electric apparatus while being shielded and sealed, through an insertion hole52formed in the shield wall50. First, the wire1has a structure where an insulating resin layer3is formed on the outer circumference of a band plate-like conductor2, and a predetermined range (the range indicated by H3in the figure) in the length direction of the conductor2is coated with a shield layer4formed by resin plating so as to cover the outer circumferential surface of the insulating resin layer3.

In the embodiment, three band plate-like wires1are placed while being arranged in the width direction, and laid in parallel in the same route. In each of the both ends of the three wires1, a seal member5made of electrically conductive rubber, and a metal-made shield shell7which is integrated with the seal member5when the seal member is molded are disposed.

The shield shell7has an elliptical ring-like shape, and is integrated with the seal member5by embedding an inner circumferential flange7ainto the rubber forming the seal member5. An outer circumferential flange7bhaving mounting holes is exposed to the outside of the rubber forming the seal member5. The shield shell7is screwed to the shield wall50of the electric apparatus while using the mounting holes, whereby the seal member5which is disposed in an inner circumferential portion of the shield shell7is held to a state where it is in close contact with the shield wall50.

The seal member5is a thick plate member having an elliptical shape, and has three wire passing holes5awhich penetrate in the thickness direction, and through which the wires1can be passed while sealing the circumferences of the wires1, respectively. In this case, the band plate-like wires1have a rectangular sectional shape, and therefore the three wire passing holes5aare formed as rectangular through holes, respectively. In order to enhance the close contact with respect to the shield wall50, an annular seal lip5bis disposed on the close contact surface with respect to the shield wall50.

A terminal portion of each of the wires1is passed through the wire passing hole5aof the seal member5to a position where the shield layer4formed by the resin plating exists, and an inner circumferential lip5cof the wire passing hole5aof the seal member5is in close contact with the outer surface of the shield layer4of the wire1. Therefore, the shield layer4and the seal member5made of electrically conductive rubber are electrically conductive with each other.

When the shield shell7is attached to the shield wall50of the electric apparatus, and the seal member5is made in close contact with the shield wall50, therefore, it is possible to waterproof seal between the wires1and the shield wall50, and at the same time the shield layers4in the outer circumferences of the wires1can be made conductive with the shield wall50of the electric apparatus to be grounded, through the seal member5, or through the seal member5and the shield shell7.

In the terminal portion of each of the wires1which are introduced into the shield wall50in this way, a non-resin plating portion H4where the resin plating is excluded in a predetermined range from an end portion of the conductor2of the wire1is ensured, a conductor exposed portion H1in which the insulating resin layer3is excluded is disposed in an end portion of the non-resin plating portion H4, and the conductor exposed portion H1is formed as a connecting portion8having a fastening hole. The range indicated by H2in the figure is a portion where the insulating resin layer3is exposed.

In the case where, as described above, the shield layer4formed by resin plating is formed on the outer circumferential surface of the wire1in the cable exposed zone (the zone exposed to the outside of the shield wall50), the shielding effect can be easily provided to the wire without requiring extra space and thickness, unlike the case where a braid is disposed for shielding. Since the seal member5made of electrically conductive rubber is interposed between the shield layer4of the wire1and the shield wall50of the electric apparatus, moreover, the shield layer4and the shield wall50can be easily made conductive with each other simply by causing the wire1to pass through the wire passing hole5aof the seal member5, and the seal member5to be in close contact with the shield wall50. Therefore, a braid and a crimping ring are not necessary, and hence the number of components can be reduced.

Although the shield shell7is used in the embodiment, the seal member5made of electrically conductive rubber is sufficient for ensuring the shielding performance. The shield shell7is required only to exert the function of causing the seal member5to be in close contact with the shield wall50. Therefore, the shield shell is not always necessary to have the shielding performance, and may be configured by a non-metallic material. In that sense, the shield shell7exerting the shielding function may be omitted.

Moreover, the seal member5itself is electrically conductive. Unlike the case where a conventional packing is used, therefore, there is no possibility that a shield leakage portion may be formed, and shielding and sealing performances which are sufficiently high can be provided. Moreover, the shield layer4formed by the resin plating is used in place of a braid. Even in a situation where the wire1is branched along the way, therefore, the structure can easily cope with the situation. Namely, the conductor2may be previously formed along the laying route, the insulating resin layer3may be then formed, and resin plating may be applied thereon. Therefore, the structure is not affected by the laying mode of the wires1, and the degree of freedom in layout is enhanced. For example, also a wire harness in which one end side is configured by a single connector, and the other end side has a shielding function for a plurality of connectors can be easily produced.

In the shielding structure of the embodiment, furthermore, a braid is not used, and hence a compact wire harness can be obtained which is free from troubles that may be caused in the case where a braid is used, i.e., extra processing such as folding into a double braid, and necessity of an extra space.

The shield layer4formed by the resin plating is only in contact with the inner circumference of the wire passing hole5aof the seal member5made of the electrically conductive rubber, and there is no possibility of breaking a plating layer unlike the case of crimping. Therefore, the shielding performance of the terminal is not impaired.

The non-resin plating portion H4is ensured in the terminal portion of the wire1, the conductor exposed portion H1in which the insulating resin layer3is excluded is disposed in the end portion of the non-resin plating portion H4, and the conductor exposed portion H1is formed as the connecting portion8having the fastening hole8. Therefore, the plating layer which is the shield layer4, and the connecting portion8with respect to the conductor2can be surely maintained in a nonconductive state.

In the embodiment, the case where the shield shell7and the seal member5are integrally formed by insert molding has been described. Alternatively, they are separately molded, and thereafter combined with each other.

Second Embodiment

FIG. 3is a perspective view of a shielding structure for a wire harness of a second embodiment of the invention, andFIG. 4is a sectional view of a portion where an end portion of the wire harness is introduced into a shield case.

Each of wires11constituting the wire harness W2in the second embodiment has a structure where three band plate-like conductors2are stacked at intervals in the thickness direction and bundled, and covered in a state where the conductors2are insulated from each other, by a resin mold portion13which functions as an integrally molded insulating resin layer. A predetermined range in the length direction of the conductor2is coated with a shield layer14formed by resin plating so as to cover the outer circumferential surface of the resin mold portion13.

In each of the both ends of the wire11, a seal member15made of electrically conductive rubber, and a metal-made shield shell17which holds the seal member15are disposed. The shield shell17has a ring-like shape, and is integrated with the seal member15by fitting an inner circumferential flange17aof the shell into an outer circumferential groove15eof the seal member15. An outer circumferential flange17bhaving mounting holes is exposed to the outside of the seal member15. The shield shell17is screwed to the shield wall50of the electric apparatus while using the mounting holes, whereby the seal member15which is disposed in an inner circumferential portion of the shield shell17is held to a state where it is in close contact with the shield wall50.

The seal member15is a thick plate member, and has a wire passing hole15awhich penetrates in the thickness direction, and through which the wire11can be passed while sealing the circumference of the wire1. In this case, the wire passing hole15ais formed into a shape which corresponds to the sectional shape of the resin mold portion13. In order to enhance the close contact with respect to the shield wall50, an annular seal lip15bis disposed on the close contact surface with respect to the shield wall50.

A terminal portion of the wire11in which the resin mold portion13is disposed is passed through the wire passing hole15aof the seal member15to a position where the shield layer14formed by the resin plating exists, and an inner circumferential lip15cof the wire passing hole15aof the seal member15is in close contact with the outer surface of the shield layer14of the wire11. Therefore, the shield layer14and the seal member15made of electrically conductive rubber are electrically conductive with each other.

When the shield shell17is attached to the shield wall50of the electric apparatus, and the seal member15is made in close contact with the shield wall50, therefore, it is possible to waterproof seal between the wire11and the shield wall50, and at the same time the shield layer14in the outer circumference of the wire11can be made conductive with the shield wall50of the electric apparatus to be grounded, through the seal member15, or through the seal member15and the shield shell17.

In the terminal portion of the wire11which is introduced into the shield wall50in this way, a non-resin plating portion H4where the resin plating is excluded in a predetermined range from an end portion of the conductors2of the wire1is ensured, a conductor exposed portion H1in which the resin mold portion (insulating resin layer)13is excluded is disposed in an end portion of the non-resin plating portion H4, and the conductor exposed portion H1is formed as the connecting portion8having a fastening hole. In the connecting portion8, the three conductors2are placed while being positionally shifted from each other so as not to overlap in the thickness direction, whereby the conductors are enabled to be coupled by bolts to terminals of the electric apparatus, respectively. The range indicated by H2in the figure is a portion where the insulating resin layer13is exposed.

The shielding structure of the second embodiment can attain the following effects in addition to the effects of the shielding structure of the above-described first embodiment. Since the plurality of the conductors2are covered in the state where the conductors are insulated from each other by the resin mold portion13, and the shield layer14formed by the resin plating is formed so as to cover the outer circumferential surface of the resin mold portion13, the plurality of conductors2can be integrally shielded while insulating them. Moreover, the shield layer14can be made conductive with the seal member15by passing the resin mold portion13through the wire through hole15aof the seal member15made of electrically conductive rubber. When the seal member15is attached to the shield wall50so as be in close contact therewith, therefore, both the sealing function and the shielding function can be simultaneously exerted.

Third Embodiment

FIG. 5is a perspective view of a shielding structure for a wire harness of a third embodiment of the invention, andFIG. 6is a sectional view of a portion where an end portion of the wire harness is introduced into a shield case.

Each of wires11constituting the wire harness W3of the third embodiment has a structure which is substantially identical with that of the second embodiment. A different point is that two protrusions13c,13econstituting a fitting groove13dare disposed on the outer circumference of the resin mold portion13covering the terminal portion of the wire11, and an inner circumferential portion of a ring-like seal member25is fitted into the fitting groove13d. The seal member25is electrically conductive with the shield layer14on the surfaces of the two protrusions13c,13e.

A flange13gwhich cooperates with the protrusion13eto constitute an engaging groove13his disposed on the outer circumference of the resin mold portion13, and a wire terminal-side movement regulating portion31is formed.

The wire terminal-side movement regulating portion31in the third embodiment is disposed on the outer circumference of the resin mold portion13which is integrally molded so as to cover the conductors2in the state where the conductors are insulated from each other. Alternatively, the wire terminal-side movement regulating portion may be disposed on the outer circumference of a resin mold portion which is molded separately from an insulating resin layer that covers the conductors2in a state where the conductors are insulated from each other, and which is externally fitted and fixed onto the insulating resin layer.

In a ring-like shield shell27having an outer circumferential flange27b, a shell-side movement regulating portion33is configured by an extending portion27ewhich is projected toward one surface of the outer circumferential flange27b, and an inner circumferential flange27awhich is formed on the whole circumference of the hole edge of a through hole27d. The height of the inner circumferential flange27asubstantially coincides with the width of the engaging groove13h, and the shell-side movement regulating portion33can enter the wire terminal-side movement regulating portion31.

When the wire terminal-side movement regulating portion31and the shell-side movement regulating portion33are relatively rotated about the axis in a state where the shield shell27is externally inserted onto the resin mold portion13, the shell-side movement regulating portion33enters the engaging groove13hof the resin mold portion13, whereby they are engaged with each other at a predetermined relative rotation position, and relative movement of the resin mold portion13and the shield shell27in the axial direction is regulated.

Here, the relative rotation position means a range from a rotation position where relative rotation in one direction is started and the shell-side movement regulating portion33begins to enter the engaging groove13h, to that immediately before the shell-side movement regulating portion33is disengaged from the engaging groove13h.

In the embodiment, a rotation regulating mechanism35which regulates relative rotation of the resin mold portion13and the shield shell27is disposed between the wire terminal-side movement regulating portion31and the shell-side movement regulating portion33.

In the embodiment, as shown inFIG. 7, the rotation regulating mechanism35is configured by a convex portion13fand a concave portion27c. The convex portion13fis disposed projectingly toward the engaging groove13hon the flange13gof the resin mold portion13, and the concave portion27cis disposed by cutting away the inner circumferential flange27aof the shield shell27. When the convex portion13fand the concave portion27care elastically latched together, the relative rotation of the resin mold portion13and the shield shell27is cancellably regulated.

As described above, the inner circumferential flange27aof the shield shell27is engaged in an adequate place with the resin mold portion13, and the metal-made shield shell27is fixed to the shield wall50of the electric apparatus, whereby the seal member25can be made in close contact with the shield wall50while performing a sealing operation.

The other configuration is identical with that of the second embodiment, and similar effects can attained.

FIGS. 7 to 12are views of assembly steps of the shield portion in the third embodiment. In the figures, the wire11is not illustrated.

As shown inFIGS. 7 to 9B, first, the resin mold portion13to which the seal member25is attached is passed through the through hole27dof the shield shell27from the side (inFIG. 7, the lower side) of the terminal portion of the wire11. At this time, as shown inFIG. 8, one side of the protrusion13eof the resin mold portion13is passed through the through hole27dwhile the shield shell27is inclined, and the other side of the protrusion13eis then passed, so that, as shown inFIG. 9, the seal member25and the protrusion13eare completely passed through the through hole27d.

As shown inFIG. 10, next, the resin mold portion13is slightly returned to the originating direction of the passing operation (in the figures, the upper direction), so that the flange13gdisposed in the resin mold portion13is pressingly contacted with an inlet portion of the through hole27dof the shield shell27and able to be relatively swung about the axis.

As shown inFIGS. 11 and 12, next, the shield shell27is swung by 90 degrees, and the wire terminal-side movement regulating portion31and the shell-side movement regulating portion33are engaged with each other, so that axial movements of the resin mold portion13and the shield shell27are regulated. Namely, the inner circumferential flange27aand extending portion27eof the shell-side movement regulating portion33enter the engaging groove13hof the wire terminal-side movement regulating portion31, and the resin mold portion13and the shield shell27become immovable in the axial direction to be fixed.

At this time, the relative rotation of the resin mold portion13and the shield shell27is regulated by the rotation regulating mechanism35which is disposed between the wire terminal-side movement regulating portion31and the shell-side movement regulating portion33. The rotation regulation due to the rotation regulating mechanism35is performed by causing the concave portion27cdisposed in the shield shell27to be engaged with the convex portion13fdisposed on the flange13gas shown inFIG. 12. Therefore, the resin mold portion13and the shield shell27are held to the integrally fixed state where axial movement and relative rotation about the axis are regulated, and the fixed state is prevented from being accidentally cancelled. In this way, the shield shell27is attached to the resin mold portion13.

When the integrally fixed state of the resin mold portion13and the shield shell27is to be cancelled, a rotational moment of a certain level or higher may be applied against the engagement force of the rotation regulating mechanism35, and the resin mold portion13and the shield shell27may be relatively rotated until the engagement of the wire terminal-side movement regulating portion31and the shell-side movement regulating portion33is cancelled.

The invention is not limited to the above-described embodiments, and may be adequately subjected to modifications, improvements, and the like. In addition, the materials, shapes, dimensions, numbers, places, and the like of the components of the above-described embodiments are arbitrary and not limited insofar as the invention is achieved.

For example, a wire to be connected may not be a flat wire (flat cable) as in the embodiments, and may be a usual wire having a circular sectional shape.

The connecting portion may have a configuration where a separate connection terminal is connected and fixed to the tip end of the conductor by crimping, welding, or the like.

The application is based on Japanese Patent Application No. 2010-290407 filed Dec. 27, 2010 and Japanese Patent Application No. 2011-254136 filed Nov. 21, 2011, and their disclosure is incorporated herein by reference.

Furthermore, it is possible eliminate the process cumbersome and problem in space which may be caused when a braid is used.

According to the shell fixture structure of the invention, it is not required to previously pass a shield shell with respect to a wire harness, and hence the workability can be improved.
