Description

  The present invention relates to a wire harness provided with a grounding fixture for fixing a shielded cable with a connector to a grounding housing.

  Vehicles represented by automobiles often have shielded cables with connectors. The shielded cable with a connector includes a shielded cable including a conductive wire and a shield member formed around the conductor, and a connector provided at an end of the shielded cable.

  For example, a shielded cable with a connector is laid as part of a signal transmission path that connects an antenna that receives a radio signal such as a broadcast signal or a radio communication signal and an electrical device such as a television receiver or a radio communication device. . In this case, the connector functions as a relay connector that connects the shield cable connected to the antenna and the shield cable connected to the electrical equipment.

  Moreover, as shown in Patent Document 1 and Patent Document 2, the shield member of the shield cable is attached to a conductive casing such as a metal panel that forms a part of the vehicle body via a metal fixture. Are electrically connected to each other. Further, when the connector of the shielded cable with connector is a relay connector, the connector is fixed to a housing such as a part of the vehicle body by a fixing tool. In this case, the metal fixture is interposed between the shield member and the conductive casing, and serves to electrically connect the shield member and ground the shield member and to fix the connector. Hereinafter, such a fixture is referred to as a grounding fixture. The shielded cable with a connector is often provided as a wire harness including a grounding fixture attached to the connector in advance.

  By fixing the connector of the shielded cable with the connector by the grounding fixture, the connector can be prevented from colliding with surrounding objects due to the vibration of the vehicle and the like, and the connector and the surrounding objects being damaged. Furthermore, since the shield member is grounded via the grounding fixture, it is possible to prevent electromagnetic noise from being mixed into the conducting wire.

  By the way, a metal fixture has many heavy equipment and processes, such as a process of cutting a part of a metal base material with a cutting machine, a process of forming a cut metal member with a mold and a punching device, and the like. It is manufactured after. Therefore, the conventional metal grounding fixture has a high manufacturing equipment cost, and also requires a lot of labor and cost to change the shape according to a design change or the like.

  Further, when a conventional metal grounding fixture is attached to the connector in advance, when the shielded cable with connector is handled, the shielded cable is easily bent and deteriorated due to the weight of the grounding fixture.

  In some cases, the shielded cable of the shielded cable with connector is laid in a state bent from the direction extending from the connector fixed by the grounding fixture to the opposite direction. In that case, a part of the shield cable extending from the connector is held in a curved state in the middle by being partly bound to the connector or the grounding fixture by a binding tool such as an adhesive tape.

  However, the connector is small, and the metal grounding fixture is also made as small as possible along the outer edge of the connector for weight reduction. Therefore, the shield cable bundled with the connector or the grounding fixture along the outer edge of the connector is held in a curved state with a relatively large curvature, that is, with a relatively small bending radius. As a result, a situation may occur in which the minimum bending radius necessary for preventing the deterioration of the characteristics of the shielded cable is not ensured in the curved portion of the shielded cable.

  As described above, the conventional wire harness including the shielded cable with the connector and the metal grounding fixture has a large manufacturing effort and cost, and the shielded cable is deteriorated due to the bending or bending of the shielding cable with a large curvature. Has a problem that it is likely to occur.

  An object of the present invention is to reduce manufacturing effort and cost in a wire harness including a shielded cable with a connector and a grounding fixture, and further prevent deterioration due to bending of the shielded cable.

The wire harness which concerns on 1st invention is equipped with each component shown below.
(1) A 1st component is a shielded cable containing the conducting wire and the shielding member formed in the circumference | surroundings.
(2) The second component is a connector provided at the end of the shielded cable.
(3) The third component is a grounding fixture made of an integral conductive member cured by heat molding of a conductive nonwoven fabric. Further, the grounding fixture is fixed to the connector gripping part held by the connector by sandwiching the connector inside, the conduction part electrically connected to the shield member of the shield cable, and the grounding case. This is a member formed with a part.

  The wire harness according to the second invention is an example of the wire harness according to the first invention. In the wire harness according to the second invention, the grounding fixture includes a cable gripping portion that holds the shielded cable extending from the connector in a curved state by sandwiching and supporting the shielded cable at least at a position away from the connector. Is further provided.

  Moreover, the wire harness which concerns on 3rd invention is an example of the wire harness which concerns on 2nd invention. In the wire harness according to the third aspect of the present invention, the cable gripping portion is a portion that holds the entire range including the connection portion with the connector in the shielded cable to the bending portion and holds the inside.

  Moreover, the wire harness which concerns on 4th invention is an example of the wire harness which concerns on 2nd invention or 3rd invention. In the wire harness according to the fourth aspect of the present invention, the cable gripping portion is a portion that also serves as a conduction portion by sandwiching a range including a portion where the shield member in the shielded cable is exposed from the outer insulation coating.

  Moreover, the wire harness which concerns on 5th invention is an example of the wire harness which concerns on either of the 1st invention from the 3rd invention. In the wire harness according to the fifth aspect of the present invention, the connector includes a conductive relay member that is in contact with the shield member of the shield cable on the inner side and a part of the connector is formed on the outer side of the exterior. Furthermore, in the wire harness according to the fifth aspect of the invention, the connector gripping portion is a portion that also serves as a conduction portion by sandwiching the connector inside while contacting a portion of the relay member formed outside the connector exterior.

  The heat forming of a nonwoven fabric, which is a soft material, is manufactured by a simple process of cutting a nonwoven fabric and subjecting the nonwoven fabric to hot press molding using a relatively simple mold and heater. Furthermore, the member hardened | cured by heat forming of the electroconductive nonwoven fabric is lightweight, and is excellent in buffering property.

  Therefore, the wire harness according to the first invention can be manufactured with simple manufacturing equipment including a grounding fixture, and further, labor and cost required for changing the shape in accordance with a design change or the like are small. Further, when the wire harness according to the first invention is handled, the shielded cable is bent and deteriorated due to the weight of the grounding fixture, and surrounding objects are damaged by the collision with the grounding fixture. Is prevented.

  According to the second invention, the shielded cable is held in a curved state while being supported at a position away from the connector by the cable gripping portion of the grounding fixture. Thus, according to the second invention, the shielded cable is curved with a relatively small curvature, i.e. with a relatively large bending radius, compared to when it is bound with a connector or a small grounding fixture along the outer edge of the connector. It is held in the state. As a result, at the curved portion of the shielded cable, the minimum bending radius necessary for preventing the deterioration of the characteristics of the shielded cable is secured, and the deterioration due to the bending of the shielded cable is prevented.

  According to the third invention, the entire range of the shielded cable including the connection portion with the connector to the curved portion is sandwiched by the cable gripping portion of the grounding fixture. As a result, the entire curved portion of the shielded cable is fixed, and even when the shielded cable is subjected to an external force, the shielded cable is kept in a curved state with a relatively small curvature, and the deterioration of characteristics is more reliably prevented.

  According to the fourth aspect of the invention, since the cable gripping portion also serves as the conducting portion, the grounding fixture can be reduced in size compared to the case where the conducting portion is provided separately. Furthermore, the cable gripping part also serving as the conduction part is in direct contact with the shield member in the shielded cable. Therefore, according to the fourth aspect of the present invention, the conductivity between the shield member and the grounding fixture is higher than when another conductive member is interposed, and the electromagnetic noise prevention performance is improved.

  Further, according to the fifth aspect, since the connector gripping portion also serves as the conducting portion, the grounding fixture can be reduced in size compared to the case where the conducting portion is provided separately. Furthermore, since the relay member of the connector electrically connects the shield member and the grounding fixture, the labor of removing a part of the insulation coating of the shield cable is saved.

A wire harness 1, 1A, 1B according to an embodiment of the present invention shown below is mounted on a vehicle such as an automobile and includes a connector 9, a shield cable 8, and a grounding fixture (10 or 10A).

<First Embodiment>
First, the configuration of the wire harness 1 according to the first embodiment of the present invention will be described with reference to FIG. In FIGS. 1 to 5, the broken line is a hidden line, and the two-dot chain line is a virtual line indicating the bolt 7.

<Shielded cable>
In the shielded cable with connector to be fixed by the grounding fixture 10, the shielded cable 8 includes a core wire 81 that is a long internal conductor, a dielectric 82 that is an insulator covering the periphery of the core wire 81, and a dielectric This is a coaxial cable having a shield member 83 that is an outer conductor formed around 82 and an insulating coating 84 that is an insulator covering the periphery of the shield member 83.

  The core wire of the shielded cable 8 is, for example, a metal wire whose main component is copper or the like. The shield member 83 is a braided wire or metal foil made of a metal wire having a knitted structure. The shield member 83 is also made of a metal whose main component is copper or the like. Moreover, the dielectric 82 and the insulation coating 84 of the shielded cable 8 are insulators made of a synthetic resin such as polyvinyl chloride, polyethylene, fluorine resin, or polyester.

  Further, in the present embodiment, the shield member 83 is exposed from the outer insulating coating 84 in a part of the shielded cable 8 by partially removing the insulating coating 84. Hereinafter, a part of the shield member 83 exposed from the insulating coating 84 is referred to as a shield exposed portion 830.

<Connector>
The connector 9 is a member that is provided at the end of the shielded cable 8 and is connected to a connector of another wire harness. The connector 9 is an insulator made of a synthetic resin such as polyvinyl chloride, polyethylene, fluorine resin, or polyester. When the connector 9 of the wire harness 1 is connected to the mating connector, the core wire 81 and the shield member 83 of the shielded cable 8 are electrically connected to the signal line and shield member of the mating cable.

<Grounding fixture>
The grounding fixture 10 is an integral conductive member that is cured by heat-molding the conductive nonwoven fabric 100 shown in FIGS. 2 and 3. As shown in FIG. 1, the grounding fixture 10 is formed with a connector gripping portion 11, a fixing portion 12 and a cable gripping portion 13.

  Here, the material of the grounding fixture 10 will be described. As the nonwoven fabric 100 that is the basis of the grounding fixture 10, for example, a nonwoven fabric including intertwined basic fibers, an adhesive resin called a binder, and conductive conductor fibers is employed.

  The adhesive resin is a resin having a melting point lower than the melting point of the basic fiber (for example, a melting point of about 110 [° C.] to about 150 [° C.]). Such a nonwoven fabric 100 is heated to a temperature lower than the melting point of the basic fiber and the conductor fiber and higher than the melting point of the adhesive resin, so that the adhesive resin melts and melts into the gap between the basic fiber and the conductor fiber. . Thereafter, when the temperature of the non-woven fabric 100 is lowered to a temperature lower than the melting point of the adhesive resin, the adhesive resin is cured in a state where the basic fibers existing around are bonded. Thereby, the shape of the nonwoven fabric 100 becomes harder than the state before heating, and is maintained by the shape shape | molded by the mold at the time of a heating.

  Hot press molding is to mold the nonwoven fabric 100 into the inner shape of the mold by heating the nonwoven fabric 100 while sandwiching and pressing the nonwoven fabric 100 to be processed.

  The adhesive resin is, for example, a granular resin or a fibrous resin. It is also conceivable that the adhesive resin is formed so as to cover the periphery of the core fiber. As described above, the fiber having a structure in which the core fiber is coated with the adhesive resin is referred to as a binder fiber. As the material of the core fiber, for example, the same material as the basic fiber is adopted.

  In addition, the basic fiber only needs to maintain the fiber state at the melting point of the adhesive resin, and various fibers can be employed in addition to the resin fiber. In addition, as the adhesive resin, for example, a thermoplastic resin fiber having a melting point lower than that of the basic fiber is employed. As a combination of the basic fiber constituting the nonwoven fabric 100 and the adhesive resin, for example, a resin fiber mainly composed of PET (polyethylene terephthalate) is adopted as the basic fiber, and a copolymer resin of PET and PEI (polyethylene isophthalate) is used. It may be adopted as an adhesive resin. In such a nonwoven fabric 100, the melting point of the basic fiber is approximately 250 [° C.], and the melting point of the adhesive resin is a temperature between about 110 [° C.] and about 150 [° C.]. When such a nonwoven fabric 100 is heated to a temperature in the range of about 110 [° C.] to about 250 [° C.] in the hot press molding and then cooled, the adhesive resin melts and is surrounded by In order to bond the basic fibers, the base fiber is molded into a shape along the inner surface of the mold, and the surface in contact with the mold is cured.

  The conductor fiber is a fibrous conductor such as carbon fiber or copper-plated fiber. The conductive nonwoven fabric 100 has conductivity by including conductor fibers, and a member obtained by curing the nonwoven fabric 100 by hot press molding also has conductivity.

  The member in which the nonwoven fabric 100 is cured by hot press molding has a certain degree of flexibility, but the hardness that maintains a certain shape is strengthened compared to the nonwoven fabric before hot press molding is performed. Is done.

  The connector grip 11 is a portion held by the connector 9 by sandwiching the connector 9 inside. The fixing portion 12 is a portion fixed to the grounding housing. The casing for grounding is, for example, a conductive casing such as a metal panel that forms a part of the vehicle body. The fixing portion 12 is formed with a mounting hole 121 which is a through hole through which the bolt 7 used for fixing to the housing for grounding is passed. The fixing portion 12 is directly fixed to the grounding case by being fixed to the grounding case, and is further connected to the grounding case via the conductive bolt 7 so as to be grounded. Electrically connected to the housing.

  The cable gripping portion 13 is formed so as to protrude from the connector gripping portion 11, and is a portion that sandwiches and supports the shield exposed portion 830 of the shielded cable 8 at a position away from the connector 9. As a result, the cable gripping portion 13 holds the shielded cable 8 extending from the connector 9 in a curved state. In the present embodiment, the cable gripping portion 13 holds the shielded cable 8 in a curved state by turning from the direction extending from the connector 9 to the opposite direction.

  In addition, since the cable gripping portion 13 in the present embodiment sandwiches a range including a part or all of the shield exposed portion 830 of the shielded cable 8, the cable gripping portion 13 and the shield member 83 are electrically connected to each other by directly contacting the shield member 83. Connected. That is, the cable gripping portion 13 in this embodiment is a portion that also serves as a conduction portion that is electrically connected to the shield member 83. As described above, the grounding fixture 10 is electrically connected by interposing between the shield member 83 and the grounding housing.

<Method for Manufacturing Wire Harness 1>
Hereinafter, the hot press molding apparatus 20 used for the apparatus of the wire harness 1 and the manufacturing method of the wire harness 1 using the same will be described with reference to FIGS. 2 and 3. 2 and 3 are front cross sections of the hot press molding apparatus 20 immediately before the hot press molding process in the manufacturing process of the wire harness 1 and when the hot press molding process is performed.

  The hot press molding apparatus 20 is used for hot press molding of the conductive nonwoven fabric 100. Hot press molding is to mold the nonwoven fabric 100 into the inner shape of the mold by heating the nonwoven fabric 100 while sandwiching and pressing the nonwoven fabric 100 to be processed.

  As shown in FIG. 2, the hot press molding apparatus 20 includes a lower mold unit 21 and an upper mold unit 22.

  The lower mold unit 21 includes lower mold frame portions 211, 212, 213, and 214 and a heater 30 that heats the lower mold frame portions 211, 212, 213, and 214. The lower mold parts 211, 212, 213, and 214 are members made of a material such as a metal having excellent thermal conductivity, and are formed in a shape corresponding to the outer shape of one half of the grounding fixture 10. .

  The lower mold parts 211, 212, 213, and 214 include a first lower molding part 211 that molds one surface of the connector gripping part 11, a second lower molding part 212 that molds one surface of the fixing part 12, A third lower molding part 213 that molds the attachment hole 121 of the fixing part 12 and a fourth lower molding part 214 that molds one surface of the cable gripping part 13 are included. The third lower molding portion 213 is a protrusion that penetrates the nonwoven fabric 100 and forms the attachment hole 121.

  On the other hand, the upper mold unit 22 includes upper mold frame parts 221, 222, 223, and 224 and a heater 30 that heats the upper mold frame parts 221, 222, 223, and 224. The upper mold parts 221, 222, 223, and 224 are members made of a material such as a metal having excellent thermal conductivity, and are formed in a shape corresponding to the outer shape of the other half of the other side of the grounding fixture 10. .

  The upper mold parts 221, 222, 223, and 224 include a first upper molding part 221 that molds the other surface of the connector gripping part 11, a second upper molding part 222 that molds the other surface of the fixing part 12, and It includes a third upper molding portion 223 that forms a hole into which the third lower molding portion 213 fits, and a fourth upper molding portion 224 that molds the other surface of the cable gripping portion 13.

  FIG. 2 shows a state in which the conductive nonwoven fabric 100, the connector 9, and the shield cable 8 before being subjected to hot press molding are placed on the lower mold parts 211, 212, 213, and 214. In the example shown in FIG. 2, a first nonwoven fabric 101 and a second nonwoven fabric 102 that are stacked from both sides of the connector 9 and the shield cable 8 are used.

  The 1st nonwoven fabric 101 is arrange | positioned over the lower mold part 211,212,213,214 over the whole. Furthermore, the connector 9 and the shielded cable 8 are disposed at positions above the first lower molding portion 211 and the fourth lower molding portion 214 on the first nonwoven fabric 101, respectively. Furthermore, the second nonwoven fabric 102 is stacked above the first nonwoven fabric 101 with the connector 9 and the shield cable 8 interposed therebetween.

  After that, as shown in FIG. 3, the upper mold parts 221, 222, 223, 224 are fitted into the lower mold parts 211, 212, 213, 214, and the lower mold parts 211, 212, 213, 214 and the upper mold parts 221, 222, 223, 224 are heated.

  The heater 30 is a heating device that heats the nonwoven fabric 100 that is the basis of the grounding fixture 10 to a temperature that is lower than the melting points of the basic fibers and conductor fibers and higher than the melting point of the adhesive resin. The two nonwoven fabrics 101 and 102 heated by the heater 30 are molded into the shapes of the lower mold frame portions 211, 212, 213, 214 and the upper mold frame portions 221, 222, 223, 224 and cured, and the connector 9 And in parts other than the part which opposes each of the shielded cable 8, it mutually adhere | attaches. As a result, the two nonwoven fabrics 101 and 102 that have undergone hot press molding become the grounding fixture 10 that is an integral molding member.

  In the example shown in FIGS. 2 and 3, the heater 30 is embedded in each of the lower mold parts 211, 212, 213, 214 and the upper mold parts 221, 222, 223, 224. However, it is also conceivable that the heater 30 is attached to the outer surfaces of the lower mold parts 211, 212, 213, 214 and the upper mold parts 221, 222, 223, 224 in a manner capable of transferring heat.

  It is also conceivable that the lower mold parts 211, 212, 213, and 214 are formed of a molded metal plate and are detachably attached to a pedestal part heated by the heater 30. Thereby, the work for setting the nonwoven fabric 100 and the shield cable 8 between the lower mold unit 21 and the upper mold unit 22 and the grounding fixture 10 which is a member formed by the nonwoven fabric 100 after hot press molding are taken out. Work becomes easier.

  As described above, the wire harness 1 is manufactured through a hot press molding process by the hot press molding apparatus 20.

<Effect>
The heat forming of the nonwoven fabric 100 which is a soft material is manufactured by a simple process of cutting the nonwoven fabric 100 and subjecting the nonwoven fabric 100 to hot press molding using a relatively simple mold and the heater 30. . Furthermore, the member hardened | cured by the thermoforming of the electroconductive nonwoven fabric 100 is lightweight, and is excellent in buffering property.

  Therefore, the wire harness 1 can be manufactured with simple manufacturing equipment including the grounding fixture 10, and further, labor and cost required for changing the shape in accordance with a design change or the like are small. Further, when the wire harness 1 is handled, the shield cable 8 is bent and deteriorated due to the weight of the grounding fixture 10, and surrounding objects may be damaged due to a collision with the grounding fixture 10. Is prevented.

  In the wire harness 1, the shielded cable 8 is held in a curved state while being supported at a position away from the connector 9 by the cable gripping portion 13 of the grounding fixture 10. Thus, the shielded cable 8 is curved with a relatively small curvature, i.e., with a relatively large bending radius, compared to when it is bound to the connector 9 or a small conventional grounding fixture along the outer edge of the connector 9. Held in. As a result, at the curved portion of the shielded cable 8, the minimum bending radius necessary for preventing the deterioration of the characteristics of the shielded cable 8 is ensured, and the deterioration due to the bending of the shielded cable 8 is prevented.

  Further, since the cable gripping portion 13 also serves as a conducting portion, the grounding fixture 10 can be reduced in size compared to the case where the conducting portion is provided separately. Furthermore, the cable gripping portion 13 that also serves as the conducting portion is in direct contact with the shield member 83 in the shielded cable 8. Therefore, the electrical conductivity between the shield member 83 and the grounding fixture 10 is higher than when another conductive member is interposed, and the electromagnetic noise prevention performance is enhanced.

Second Embodiment
Next, a wire harness 1A according to a second embodiment of the present invention will be described with reference to FIG. This wire harness 1A includes a grounding fixture 10A that differs from the grounding fixture 10 of the wire harness 1 shown in FIG. 4, the same components as those shown in FIG. 1 are given the same reference numerals. Hereinafter, only different points of the wire harness 1A from the wire harness 1 will be described.

  The grounding fixture 10A of the wire harness 1A, like the grounding fixture 10, is a member obtained by hot press molding of the conductive nonwoven fabric 100, and includes a connector gripping portion 11, a fixing portion 12, and a cable gripping portion 13A. Have

  As shown in FIG. 4, the cable gripping portion 13 </ b> A of the grounding fixture 10 </ b> A is a portion that sandwiches and holds the entire range including the connection portion with the connector 9 in the shielded cable 8 to the curved portion.

  The cable gripping portion 13 </ b> A includes a portion that sandwiches and supports the shield exposed portion 830 of the shielded cable 8 at a position away from the connector 9. That is, the cable gripping portion 13 </ b> A in the present embodiment is also a portion that doubles as a conduction portion that is electrically connected to the shield member 83, similarly to the cable gripping portion 13. Note that the wire harness 1 </ b> A is also manufactured through the same process as the process of manufacturing the wire harness 1.

<Effect>
When the wire harness 1A is employed, the same effect as that obtained when the wire harness 1 is employed is obtained. Furthermore, in the wire harness 1A, the entire range of the shielded cable 8 including the connecting portion with the connector 9 to the curved portion is sandwiched by the cable gripping portion 13A of the grounding fixture 10A. As a result, the entire curved portion of the shielded cable 8 is fixed, and even when the shielded cable 8 is subjected to an external force, the curved state is maintained with a relatively small curvature, and the deterioration of characteristics is more reliably prevented.

<Third Embodiment>
Next, a wire harness 1B according to a third embodiment of the present invention will be described with reference to FIG. The wire harness 1B includes a connector 9B that is different from the connector 9 of the wire harness 1 shown in FIG. 5, the same components as those shown in FIG. 1 are denoted by the same reference numerals. Hereinafter, only different points from the wire harness 1 in the wire harness 1B will be described.

  The connector 9 </ b> B of the wire harness 1 </ b> B includes a conductive plate 91 that is a conductive member that is in contact with the shield member 83 of the shielded cable 8 on the inner side and a part of which is formed outside the exterior. The conduction plate 91 is an example of a relay member.

  In the wire harness 1B, the connector gripping portion 11 of the grounding fixture 10 is formed so as to sandwich the region including the conduction plate 91 in the connector 9B. Accordingly, the connector gripping part 11 has a structure in which the connector 9B is sandwiched inside while being in contact with a portion of the conduction plate 91 formed outside the exterior of the connector 9B.

  That is, in the present embodiment, the connector gripping part 11 is a part that also serves as a conduction part that is electrically connected to the shield member 83. Therefore, in the wire harness 1B, the shield exposed portion 830 is not formed on the shield cable 8, and the cable gripping portion 13 does not function as a conduction portion. In addition, the wire harness 1B is also manufactured through the same process as the process for manufacturing the wire harness 1.

<Effect>
When the wire harness 1B is employed, the same effect as that obtained when the wire harness 1 is employed is obtained. Furthermore, in the wire harness 1B, since the connector gripping part 11 also serves as a conducting part, the grounding fixture 10 can be reduced in size compared to the case where the conducting part is provided separately. Furthermore, since the conduction plate 91 of the connector 9B electrically connects the shield member 83 and the grounding fixture 10, the trouble of removing a part of the insulation coating 84 of the shield cable 8 is saved.

<Others>
In the wire harness 1A, the connector 9B of the wire harness 1B may be employed instead of the connector 9. In this case, the shield exposed portion 830 may not be provided in the shielded cable 8.

  Moreover, when it is not necessary to hold | maintain the shielded cable 8 in the curved state, it is also considered that the wire harness 1B is provided only with the remaining structure except the cable holding part 13 of the fixing tool 10 for grounding. Further, in the grounding fixtures 10 and 10A, the cable gripping portion 13 does not always hold the shielded cable 8 in a curved state by turning from the direction extending from the connector 9 to the opposite direction.

  For example, it is also conceivable that the cable gripping portion 13 holds the shielded cable 8 in a state in which it is bent from the direction extending from the connector 9 in a direction that forms an angle of less than 180 ° with respect to that direction.

  Further, in the grounding fixtures 10 and 10A, it is also conceivable that the connector gripping part 11 sandwiches the entire connectors 9 and 9B, that is, encloses the entire connectors 9 and 9B.

  It is also conceivable that one conductive nonwoven fabric 100 is used in place of the two conductive nonwoven fabrics 101 and 102 in the manufacturing process of the grounding fixtures 10 and 10A. In this case, one conductive nonwoven fabric 100 is disposed so as to sandwich the connectors 9 and 9B and the shielded cable 8 from both sides by being folded twice.

  In addition, the mounting holes 121 of the grounding fixtures 10 and 10A may be formed by a punching device after hot press molding instead of being formed in the hot press molding step.
