Description

  The present invention relates to a conductive member.

  In an electronic device incorporating an electronic component that becomes a noise source, as a noise countermeasure, the noise source is covered with a metal shield case. When a cable is led out from the inside of such a shield case, a cutout or a hole used as a cable insertion port may be provided in a metal panel provided in the shield case, and the cable may be passed through the cable insertion port.

At this time, in order to prevent the cable from being damaged at the edge on the inner peripheral side of the cable insertion port, or to stabilize the position of the cable, a cable holder for holding electric wires inserted into the cable insertion port is used. (For example, refer to Patent Document 1). In general, this type of cable holder is made of a resin material, and is in contact with the cable at a resin portion softer than metal, thereby suppressing damage to the cable.
JP 11-54959 A

However, even when the shield case as described above is provided, noise on the cable in the shield case may leak out of the shield case through the cable.
Conventionally, the metal parts are attached to the cable holder made of the resin material as described above, or the metal sheet metal parts are attached to the cable holder made of the resin material, and these metal portions are fixed. Noise countermeasures have been taken by electrically connecting the ground wire of the cable and the shield case.

  However, when metal plating is applied to a cable holder made of a resin material, the bonding strength between the resin material and the metal is not necessarily strong. Therefore, if the bonding height of the metal plating to the resin is not sufficiently secured, if the metal plating is peeled off due to friction with the cable, there is a possibility that a relatively large thin-film metal fragment may fall off. If the metal-like piece is placed on the printed wiring board, it may cause a short circuit.

  On the other hand, when a metal sheet metal part is attached to a cable holder made of a resin material, the sheet metal part itself is not easily dropped from the cable holder unlike the metal plating. Even if metal plating is applied to the sheet metal part, the metal plating applied to the metal sheet metal part is different from the metal plating applied to the resin part. Even if there is this friction, it does not lead to a situation in which the thin-film metal piece is peeled off.

  However, since the sheet metal part itself is made of metal that is harder than the resin material, if the sheet metal part may damage the cable, it means that the cable holder is provided. It will disappear. Therefore, it is necessary to design the shape of the sheet metal part by paying sufficient attention so that the edge of the sheet metal part does not hit the cable, and it takes time and effort to design the sheet metal part. There was a problem that it took time to design the mold.

In addition, the above problems are the problems which arose similarly also in things other than the cable holder attached to the edge of the cable insertion opening inner peripheral side.
For example, when a printed wiring board is fixed to a metal panel of a housing via a spacer made of a resin material, the conductor pattern on the printed wiring board and the metal panel are electrically connected via a conductive contact. However, if this type of conductive contact has a structure in which metal plating is applied to a resin part, the metal plating may be peeled off as described above, and a thin-film metal fragment may be formed. Invite the problem as you did. Also, if the conductive contact is a “metal sheet metal part” or “a structure in which a metal sheet metal part is attached to a resin part”, the edge of the sheet metal part is designed not to hit another member. Therefore, it takes time to design and mold.

  In addition, various clamps, ducts, and guide rails are also used when attaching various clamps for holding cables, ducts for guiding cables along a predetermined route, and guide rails to a metal panel. If these are resin parts, a conductor can be added to these resin parts to electrically connect the ground wire of the cable and the metal panel. However, if metal plating is performed on a resin component in order to provide such a conductor, a thin-film metal fragment may be peeled off. In addition, when a metal sheet metal part is attached to a resin part in order to provide a conductor, in that case, it is necessary to design the edge of the sheet metal part so that it does not hit another member. It takes time to make the mold.

  The present invention has been made in order to solve the above-described problems, and the purpose of the present invention is a case where metal plating is applied to a resin component while the structure is such that a metal conductor is attached to the resin component. Thus, there is no worry that the thin-film metal piece is peeled off, and it is an object to provide an unnecessary conductive member in consideration of edge countermeasures as in the case where a sheet metal part is attached to a resin part.

The characteristic configuration employed in the present invention will be described below.
The conductive member according to claim 1 is a conductive member that is used in contact with each of the first and second members and forms a conductive path between the first member and the second member. A resin material main body and a metal wire attached to the main body, the metal wire contacting at least one member of the first and second members, A soft conductor that forms at least a part of the conductive path and is in contact with at least one of the first and second members at a conductive contact surface that is more flexible than the metal wire. The soft conductor is attached to the main body by being restrained by the metal wire .

According to the conductive member configured as described above, since the metal wire is provided as the member that forms the conductive path, the metal wire comes into contact with at least one of the first and second members. However, unlike the case where the metal plating is applied to the resin part, the thin-film metal piece is not peeled off. In addition, as the metal wire, it is possible to use a metal wire having a substantially circular cross section, such as a sheet metal part, which has no edge. Therefore, unlike a sheet metal part attached to a resin part, Edge measures are also unnecessary. Therefore, a short circuit or the like due to peeling off of the thin-film metal piece does not occur, and the design is not time-consuming for edge countermeasures.
Moreover, the soft conductor as described above is provided, and the metal wire functions as a member for fixing the soft conductor, and at the same time, the metal wire and the soft conductor are electrically connected. Therefore, about the member which a soft conductor contacts, it can make it hard to be damaged more than the case where a metal wire contacts.

  In the conductive member of the present invention, the metal wire only needs to form at least a part of the conductive path by contacting at least one of the first and second members. That is, the metal wire can adopt a configuration in which only one of the first and second members is in contact with the metal wire, or a configuration in which both the first and second members are in contact with each other.

  When the metal wire is in contact with both the first and second members, the metal wire has the above-described functions and effects on both the first and second members. On the other hand, when the metal wire is in contact with only one of the first and second members, the metal wire exhibits the above-described action and effect with respect to either one of the members.

  By the way, when the metal wire is in contact with only one of the first and second members, another conductor is disposed between the other and the metal wire, A conductive path may be formed between the second member and the second member. In this case, the other conductor may be any conductor as long as it does not hinder the operation and effect of the present invention. Specifically, the thin-film metal piece does not peel off even when it comes into contact with the metal wire, and As long as there is no edge like a sheet metal part, what kind of thing may be sufficient. Examples of such a conductor include a conductive mesh, a conductive cloth, a conductive rubber, a conductive elastomer, a conductive sponge, and the like.

In the conductive member of the present invention, the metal wire may be processed into a shape that can be attached to the main body by a wire forming machine.

  According to the conductive member configured in this way, the metal wire is processed into a shape that can be attached to the main body by a wire forming machine, and therefore a processing method that gradually winds the metal wire around the main body is In contrast, the metal wire can be easily attached to the main body by processing the metal wire into an intended shape in advance.

Further, the conductive member of the present invention, the metal wire may be shaped to press with an elastic deformation to the body.

  According to such a conductive member, the metal wire can be attached to the main body by utilizing the spring property of the metal wire. In addition, with such an attachment method, the main body and the metal wire are in an attachment state that allows some relative sliding, so that a part of the main body and the metal wire can be bent. In addition, a structure in which one does not excessively restrain the other and is easily bent can be obtained.

Further, the conductive member of the present invention, the metal wire, the first, of the second member, may be shaped to press with the elastic deformation on at least one of the members.

  According to such a conductive member, it is difficult to generate an extra space between the metal wire and the member to which the metal wire is pressed between the first and second members, and the metal wire fits firmly. The electrical connection between the member to which the metal wire is pressed and the metal wire can be made more reliable.

Further, in the conductive member of the present invention , the first member is a member having a metal panel having a ground potential and having a notch or a hole used as a cable insertion port in the metal panel, The second member is a cable having a ground wire, and the main body covers the edge on the inner peripheral side of the cable insertion port, so that the cable passed through the cable insertion port directly contacts the edge. The metal wire may form at least a part of the conductive path formed between the ground wire and the metal panel of the cable.

  According to such a conductive member, the cable passed through the cable insertion port can be prevented from directly contacting the edge on the inner peripheral side of the cable insertion port, and the ground wire and the metal panel included in the cable can be electrically connected. Since noise can be connected, noise leakage through the cable can be prevented.

In the conductive member of the present invention , the first and second members are members each including a plate-like portion having a portion having a ground potential, and the main body includes the first member and the second member. The metal wire has a portion having the ground potential of the first member and the ground potential of the second member. it may form at least part of the conductive path formed between the portion having.

  According to such a conductive member, it is possible to form a predetermined gap between the first member and the second member, and to electrically connect the parts having the ground potential of both members. Can do.

Next, the best mode for carrying out the present invention will be described with specific examples.
(1) First Embodiment First, a first embodiment will be described.

  FIG. 1 is a six-side view of a cable holder 1 corresponding to an example of a conductive member of the present invention, where (a) is a plan view, (b) is a left side view, (c) is a front view, and (d). Is a right side view, (e) is a bottom view, and (f) is a rear view. 2A and 2B are six views of the main body 3 included in the cable holder 1, wherein FIG. 2A is a plan view, FIG. 2B is a left side view, FIG. 2C is a front view, and FIG. e) is a bottom view, and (f) is a rear view. FIG. 3 is a six-sided view of the metal wire 5 provided in the cable holder 1, wherein (a) is a plan view, (b) is a left side view, (c) is a front view, (d) is a right side view, (E) is a bottom view and (f) is a rear view.

  FIG. 4 is a reference diagram showing the overall configuration of the cable holder 1. FIG. 5 is a reference diagram of the form of the metal wire 5, (a) is a perspective view showing the form immediately after wire forming, and (b) shows the final form after additional caulking. It is a perspective view. FIG. 6 is an explanatory diagram showing a procedure for attaching the cable holder 1.

  As shown in FIGS. 1A to 1F, the cable holder 1 includes a main body 3 made of a resin material (made of polyamide in the present embodiment), a metal wire 5, and a foamed polyurethane core. And a soft conductor 7 having a structure covered with a conductive cloth.

  As shown in FIGS. 2A to 2F, the main body 3 includes a cable housing portion 11 formed in a substantially U-shape and an opening / closing portion 13 extending from the cable housing portion 11. And. Near the base of the opening / closing portion 13, a hinge portion 15 is formed which is thinner than other portions. Further, an engaging portion 17 is formed at the tip of the opening / closing portion 13, while an engaged portion 19 is formed in the cable housing portion 11. In such a main body 3, when the hinge portion 15 is bent, the engaging portion 17 and the engaged portion 19 can be engaged, whereby the opening and closing portion 13 can open the ring opening portion of the cable housing portion 11. By closing, the main body 3 can be formed into an annular shape (see FIG. 6D).

  The metal wire 5 has a basic shape formed by a wire forming machine. As shown in FIGS. 3A to 3F, the metal wire 5 is formed on the protrusions and recesses formed on the main body 3. They are bent together, so that when they are attached to the main body 3, they are fitted into a predetermined position on the main body 3.

  The portions at both ends of the metal wire 5 are pressure contact portions 21 and 22 that are in pressure contact with the main body 3. By pressing the main body 3 between the pressure contact portions 21 and 22, the metal wire 5 is pressed against the main body 3. Suppresses rattling.

  Further, a portion near the center of the metal wire 5 is a holding portion 23 that holds the soft conductor 7. This holding part 23 is processed into the form as shown in FIG. 5A immediately after the forming process by the wire forming machine, but after being attached to the main body 3 in this form, an additional part is provided. Caulking is performed to form a shape as shown in FIG. When performing the caulking process, the holding portion 23 holds the soft conductor 7 attached on the main body 3 so as to be tightened, so that the metal wire 5 and the soft conductor 7 are electrically connected. Become.

  The cable holder 1 is attached to the metal panel P as shown in FIG. The metal panel P constitutes a part of a shield case (corresponding to the first member in the present invention), and the metal panel P is formed with a notch D used as a cable insertion port. .

  When attaching the cable holder 1 to the notch D, the main body 3 and the metal wire 5 may be pushed into the notch D while being elastically deformed. When the cable holder 1 is pushed into an appropriate position, the shape of the elastically deformed portion of the main body 3 and the metal wire 5 is restored, and the unevenness on the main body 3 engages with the unevenness of the notch D. The tool 1 is not easily removed from the notch D. In this state, the metal wire 5 comes into contact with the metal panel P.

  When the cable holder 1 is thus mounted in the notch D, next, as shown in FIG. 6B, a cable C (corresponding to the second member in the present invention) is introduced into the cable holder 1. . At this time, the cable C is arranged so that the outermost coating layer (not shown) is partially peeled off and the ground wire (not shown) in the lower layer is in contact with the soft conductor 7.

  Then, as shown in FIG. 6C, the opening / closing part 13 is closed. As a result, the cable C is held by the cable holder 1 as shown in FIG. In this state, the soft conductor 7 is pressed against the ground wire of the cable C with deformation, the metal wire 5 is also pressed into the soft conductor 7 in a state of narrowing the soft conductor 7, and the metal wire 5 As described above, it is in contact with the metal panel P. Therefore, the metal wire 5 and the soft conductor 7 form a conductive path between the metal panel P and the ground wire of the cable C.

  If the cable holder 1 as described above is attached to the metal panel P, the main body 3 included in the cable holder 1 can cover the edge on the inner peripheral side of the notch D. Can be prevented from coming into direct contact with the inner peripheral edge of the notch D. Therefore, the cable C can be prevented from being damaged at the edge on the inner peripheral side of the notch D.

  Moreover, since the metal wire 5 and the soft conductor 7 form a conductive path between the metal panel P and the ground wire of the cable C, the ground wire of the cable C and the metal panel P can be electrically connected. It is possible to prevent or suppress noise from leaking via C.

  In particular, since the metal wire 5 is used as a member for forming the conductive path, unlike the case where the metal plating is applied to the resin component, even if the metal wire 5 contacts the metal panel P or the cable C, the thin film The metal-like metal pieces are not peeled off. Therefore, a short circuit or the like caused by peeling off the thin-film metal piece does not occur.

  Further, since the metal wire 5 having a circular cross section without an edge can be used, unlike the case where a sheet metal part is attached to a resin part, it is not necessary to take measures against the edge of the member forming the conductive path. Therefore, it does not take time to design for edge countermeasures.

  Further, since the metal wire 5 is pressed against the main body 3 by utilizing the spring property of the metal wire 5, the metal wire 5 can be attached to the main body 3 without rattling. Also, with such an attachment method, the main body 3 and the metal wire 5 are in an attachment state in which some relative sliding is allowed, so that when the main body 3 and the metal wire 5 are attached to the notch D, Even if one part is deformed, one does not excessively restrain the other, and the entire cable holder 1 can be easily deformed. Further, since the spring property of the metal wire 5 is used, it is possible to provide a high spring property that cannot be realized only by the resin main body 3, and the pressure contact strength against the cable C and the pressure contact strength against the metal panel P can be increased. This can be improved over the resin body 3 alone.

  In addition, since the soft conductor 7 is provided and the soft conductor 7 is brought into pressure contact with the cable C, the cable C can be made less likely to be damaged than the metal wire 5 directly contacts. Moreover, even when the diameter of the cable C is thick, the cable C can be held by the soft conductor 7 being crushed. Therefore, the single cable holder 1 can handle cables C of various thicknesses. Can do. Furthermore, if the thickness of the soft conductor 7 is changed, cables C having various thicknesses can be handled without changing the metal wire 5.

In addition, since the soft conductor 7 is constrained by the metal wire 5, the attachment strength of the soft conductor 7 is higher than that in which the soft conductor 7 is simply pasted with an adhesive or a double-sided adhesive tape, Even when the soft conductor 7 receives a force from the cable C, it does not peel off from the main body 3.
(2) Second Embodiment Next, a second embodiment will be described. In the second and subsequent embodiments, although a part of the configuration is different from the first embodiment, there are many common parts. Therefore, in the following description, the differences from the first embodiment are mainly described. Detailed description will be made with respect to the common parts with the same reference numerals as in the first embodiment, and detailed description thereof will be omitted.

  FIG. 7 is a six-sided view of the cable holder 31 corresponding to an example of the conductive member of the present invention, where (a) is a plan view, (b) is a left side view, (c) is a front view, and (d). Is a right side view, (e) is a bottom view, and (f) is a rear view. FIG. 8 is a six-sided view of the metal wire 35 included in the cable holder 31, (a) is a plan view, (b) is a left side view, (c) is a front view, (d) is a right side view, (E) is a bottom view and (f) is a rear view. FIG. 9 is a reference diagram showing the overall configuration of the cable holder 1.

  As shown in FIGS. 7A to 7F, the cable holder 31 includes a body 3 made of a resin material (made of polyamide in the present embodiment) and a metal wire 35, and functions thereof. The method of use is the same as that of the cable holder 1 of the first embodiment. The main body 3 is exactly the same as the cable holder 1 of the first embodiment.

  On the other hand, the metal wire 35 is formed by a wire forming machine as in the first embodiment, but as shown in FIGS. 8A to 8F, a part of the shape is the first. It is processed into a shape different from the metal wire 5 of one embodiment.

  Specifically, the portions at both ends of the metal wire 35 are the press contact portions 21 and 22 that press-contact the main body 3, and this portion is arranged between the press contact portions 21 and 22 as in the first embodiment. By press-contacting in a sandwiched manner, the metal wire 35 plays a role of suppressing rattling with respect to the main body 3.

  On the other hand, unlike the metal wire 5 of the first embodiment, the metal wire 35 is bent into a shape having a cable receiving portion 41 and a cable pressure contact portion 43. The cable receiving portion 41 and the cable pressure contact portion 43 are portions that function as contact points with the cable instead of the soft conductor 7 shown in the first embodiment.

  In particular, since the cable pressure contact portion 43 is in a form that is very easily elastically deformed, it is possible to introduce a thin cable up to a position in contact with the cable receiving portion 41, even a slightly thicker cable, The cable can be introduced to a position where it comes into contact with the cable receiving portion 41 while elastically deforming the cable pressing portion 43.

  Moreover, since the cable press-contact part 43 press-contacts a cable with the elastic deformation of such a cable press-contact part 43, the electrical connection of a cable and the cable press-contact part 43 can be made more reliable.

Even in the cable holder 31 configured as described above, a conductive path between the metal panel and the ground wire included in the cable can be formed via the metal wire 35, so that the resin component is subjected to metal plating. There is no fear that the thin-film metal piece is peeled off, and it becomes an unnecessary conductive member to consider edge measures as in the case where a sheet metal part is attached to a resin part.
(3) Third Embodiment Next, a third embodiment will be described.

  FIG. 10 is a six-side view of the cable holder 51 corresponding to an example of the conductive member of the present invention, where (a) is a plan view, (b) is a left side view, (c) is a front view, and (d). Is a right side view, (e) is a bottom view, and (f) is a rear view. FIG. 11 is a six-sided view of the metal wire 55 provided in the cable holder 51, (a) is a plan view, (b) is a left side view, (c) is a front view, (d) is a right side view, (E) is a bottom view and (f) is a rear view.

  As shown in FIGS. 10A to 10F, the cable holder 51 includes a main body 3 made of a resin material (made of polyamide in the present embodiment) and a metal wire 35, and functions thereof. The method of use is the same as that of the cable holder 1 of the first embodiment. The main body 3 is exactly the same as the cable holder 1 of the first embodiment and the cable holder 31 of the second embodiment.

  On the other hand, the metal wire 55 is formed by a wire forming machine as in the first and second embodiments. However, as shown in FIGS. 11 (a) to 11 (f), a part of the metal wire 55 is formed. The shape is processed into a shape different from the metal wire 5 of the first embodiment and the metal wire 35 of the second embodiment.

  Specifically, the metal wire 55 omits only the cable pressure contact portion 43 except for the cable reception portion 41 and the cable pressure contact portion 43 included in the metal wire 35 of the second embodiment. It is a form corresponding to a thing.

  When the metal wire 55 having such a configuration is employed, unlike the second embodiment, the cable pressure contact portion 43 does not exist, and therefore the cable pressure contact portion 43 cannot be pressed against the cable. Cable can be introduced into the cable holder.

  Therefore, when it is desired to hold a relatively thin cable, it is preferable to use the cable holder 31 exemplified in the second embodiment. On the other hand, when a relatively thick cable is desired to be held, the cable holder 31 is exemplified in the third embodiment. It is preferable to use the cable holder 51 made.

Even in the cable holder 51 configured as described above, a conductive path between the metal panel and the ground wire included in the cable can be formed via the metal wire 55, so that the resin component is subjected to metal plating. There is no fear that the thin-film metal piece is peeled off, and it becomes an unnecessary conductive member to consider edge measures as in the case where a sheet metal part is attached to a resin part.
(4) Fourth Embodiment Next, a fourth embodiment will be described. In the first to third embodiments described above, the conductive member that functions as a cable holder has been described. In the fourth embodiment, a conductive member that functions as a spacer will be described.

  12A and 12B are six views of the spacer 61 corresponding to an example of the conductive member of the present invention, where FIG. 12A is a plan view, FIG. 12B is a left side view, FIG. 12C is a front view, and FIG. (E) is a bottom view and (f) is a rear view. FIGS. 13A and 13B are six views of the main body 63 included in the spacer 61, where FIG. 13A is a plan view, FIG. 13B is a left side view, FIG. 13C is a front view, FIG. Is a bottom view, and (f) is a rear view. 14A and 14B are six views of the metal wire 65 included in the spacer 61, where FIG. 14A is a plan view, FIG. 14B is a left side view, FIG. 14C is a front view, and FIG. 14D is a right side view. ) Is a bottom view, and (f) is a rear view. FIG. 15 is a reference diagram showing the overall configuration of the spacer 61. FIG. 16 is a reference diagram illustrating a usage state of the spacer 61.

As shown in FIGS. 12A to 12F, the spacer 61 includes a main body 63 made of a resin material (made of polyamide in the present embodiment) and a metal wire 65.
As shown in FIGS. 13A to 13F, the main body 63 has a structure in which a first attachment portion 73 is provided at one end of the support 71 and a second attachment portion 75 is provided at the other end of the support 71. It has become.

  An attachment groove 71a for attaching the metal wire 65 is formed in the support 71, and the attachment position of the metal wire 65 with respect to the support 71 is prevented from shifting by attaching the metal wire 65 to the attachment groove 71a.

  The first mounting portion 73 has a structure in which mounting holes and engagement holes having a predetermined shape are formed in the metal panel P in advance and can be fixed to the metal panel P using the mounting holes and the engagement holes. It has become.

  More specifically, the first mounting portion 73 is inserted into the mounting hole formed in the metal panel P from one side of the front and back surfaces of the metal panel P, and is hooked on the other side, and the locking projection 73a. A pressure contact piece 73b that is in pressure contact with the one side.

  The mounting hole formed in the metal panel P has a shape that allows the locking projection 73a to pass therethrough, and after inserting the locking projection 73a into the mounting hole, the axis that is the insertion direction of the spacer 61 When the spacer 61 is rotated 90 degrees with the rotation stopped, the locking projection 73a becomes an odd-shaped attachment hole that catches the metal panel P.

  Engaging holes are formed on both sides of the mounting hole. After inserting the locking projection 73a into the mounting hole and then rotating the spacer 61 by 90 degrees, the convex portion 73c at the tip of the pressure contact piece 73b is engaged. It fits in the fitting hole, and thereby the rotation of the spacer 61 is restricted.

  When the locking projection 73a is attached to the mounting hole in this way, the locking projection 73a cannot be pulled straight out of the mounting hole. In addition, when the locking projection 73a is attached to the mounting hole, the pressure contact piece 73b is elastically deformed and pressed against the metal panel P, thereby energizing the locking projection 73a in the direction of pulling out. As a result, the metal panel P is in a state of being firmly sandwiched between the locking protrusion 73a and the pressure contact piece 73b, and the first mounting portion 73 is fixed to the metal panel P without rattling. .

  On the other hand, the second mounting portion 75 has a structure in which a mounting hole having a predetermined shape is formed in the printed wiring board PWB in advance and can be fixed to the printed wiring board PWB using the mounting hole.

  More specifically, the second mounting portion 75 is a check piece 75a that is inserted from one side of the front and back surfaces of the printed wiring board PWB into the mounting hole formed in the printed wiring board PWB and caught on the other side. And a pressure contact piece 75b that is in pressure contact with the one side.

  The mounting hole formed in the printed wiring board PWB is a hole having a slightly smaller diameter than the outer diameter of the check piece 75a, and the check piece 75a is located on the one side of the mounting hole formed in the printed wiring board PWB. When inserted from the outer diameter, the outer diameter is reduced with elastic deformation. Then, after passing through the attachment hole, the shape of the elastically deformed portion is restored to be expanded, and the other surface is caught.

  Further, the check piece 75a is attached with an expansion blocking piece 75c that abuts the inner peripheral surface of the mounting hole formed in the printed wiring board PWB and prevents the check piece 75a from excessively expanding. ing. Even if the check piece 75a passes through the mounting hole, the expansion blocking piece 75c does not completely pass through the mounting hole and remains on the inner peripheral side of the mounting hole. Excessive expansion of the stop piece 75a is prevented.

  When the check piece 75a is attached to the attachment hole in this way, the check piece 75a cannot be pulled out of the attachment hole straight as it is. In addition, when the check piece 75a is attached to the attachment hole, the pressure contact piece 75b is elastically deformed and press-contacted with the printed wiring board PWB, thereby energizing the check piece 75a in the pulling direction. As a result, the printed wiring board PWB is securely sandwiched between the check piece 75a and the pressure contact piece 75b, and the second mounting portion 75 is fixed to the printed wiring board PWB without rattling. become.

  Further, the metal wire 65 is formed by a wire forming machine, and is bent in accordance with a convex portion or a concave portion formed in the main body 63 as shown in FIGS. 14 (a) to 14 (f). When the attachment portion 81 is processed and attached to the attachment groove 71 a formed in the column 71 of the main body 63, it is fixed in a predetermined position on the main body 63.

  The portions at both ends of the metal wire 65 are in pressure contact with the first contact portion 83 that is pressed against the metal panel P by its own spring property and the pattern having the ground potential of the printed wiring board PWB by its own spring property. It becomes the 2nd contact part 85 to do.

  As shown in FIGS. 16A to 16C, the spacer 61 configured as described above is attached to the metal panel P and is arranged in parallel to the metal panel P. The plate PWB can be held. Note that the mounting holes formed in the metal panel P and the printed wiring board PWB for mounting the spacer 61 are both holes that penetrate the metal panel P and the printed wiring board PWB. These are shown in a state where the metal panel P and the printed wiring board PWB are cut in the vicinity of the mounting holes for the sake of convenience in order to make the mounting structure of the spacer 61 easier to see.

  Specifically, for example, the cable holder of the first embodiment is configured to be attached to the notch, but the second embodiment is different from the second embodiment with respect to the annular structure that can be opened and closed as in the first embodiment. A cable holder that can hold a cable at a position away from the metal panel P by a predetermined distance can be configured by adding a support column that can be attached to the same metal panel P.

  Even in this case, noise countermeasures and the like can be realized by electrically connecting the ground wire of the cable and the metal panel using a metal wire. Moreover, in this case as well, there is no worry that the thin-film metal fragments will peel off, as in the case of metal plating on resin parts, and it is not necessary to consider edge countermeasures as in the case of attaching sheet metal parts to resin parts. Become.

  In addition, when attaching ducts and guide rails for wiring the cable along a predetermined route to the metal panel, by providing a conductive path made of the metal wire to the metal panel, A metal panel can be electrically connected.

  Moreover, in the said 1st Embodiment, although the soft conductor 7 of the structure which coat | covered the foaming polyurethane core material with the electroconductive cloth was illustrated, the specific structure of such a soft conductor is limited to the above thing.
