Description

  The present invention relates to a shield tube assembly structure, a shield cable structure, and a shield cable fixing method that are excellent in distinguishability and handleability.

  Conventionally, metal pipes such as steel pipes and aluminum pipes are used as protective pipes for cables used in automobiles, for example. The metal tube is usually provided at the lower part of the vehicle body. Since the protective tube is a metal tube, the protective tube itself has a shielding property against external noise, and is not easily affected by noise. However, since the metal tube is processed into a predetermined shape, the processing cost is high, and the degree of freedom in layout and arrangement of the electronic device or the like is low. Moreover, since it is metal, there also exists a problem of weight. Therefore, a resin pipe having shielding properties has been studied.

  As such a shield tube, for example, there is a method of forming a corrugated tube having a shielding property by forming a metal layer on a resin corrugated tube using an electroless plating method (Patent Document 1, Patent). Reference 2).

JP 9-298382 A Japanese Patent Laid-Open No. 10-185015

  However, the corrugated tubes of Patent Document 1 and Patent Document 2 do not take into account a shield tube for a high-voltage cable used in an electric vehicle or the like. Usually, when used as a high voltage cable for such an automobile, it is necessary to distinguish from other general protective tubes and the like from the viewpoint of safety. For example, it is necessary to color only the protective tube of such a high voltage line. However, since there is a plating layer outside the cable protection tube, such coloring is difficult. For example, if the surface of a conventional protective tube is simply painted, the coating may be peeled off.

  On the other hand, since the high-voltage piping used in the automobile is installed in the lower part of the automobile, the plating layer (shield layer) on the surface may be damaged when a stone or the like collides, and the shielding performance may be deteriorated. Therefore, it is necessary to reliably protect such a shield layer.

  The present invention has been made in view of such problems, and can be reliably identified with other cables, etc., has excellent durability, and is excellent in handling structure such as installation work. It is an object to provide a shielded cable structure and a shielded cable fixing method.

  In order to achieve the above-described object, a first invention is an assembly structure of a shield tube in which an outer tube is covered with a shield tube, and an outer periphery of a resin tube body having a corrugated shape on at least a part of the outer surface is electrically conductive. A shield tube in which a member is coated to form a shield layer; and an outer tube having a corrugated shape on an inner surface thereof, the outer tube being formed of a colored resin. The wave pitch of the resin tube having a corrugated shape at least partially differs from the wave pitch of the outer tube, or the width of the outer surface of the convex portion of the resin tube is the width of the inner surface of the concave portion of the outer tube. Or the width of the concave outer surface of the resin tube is smaller than the width of the convex inner surface of the outer tube, so that the corrugated shape of the inner surface of the outer tube is the corrugated shape of the resin tube. It is the assembly structure of the shield pipe | tube characterized by not fitting in. Here, since the corrugated shape formed on the outer surface of the shield tube only needs to be at least partially, it is not limited to a part of the outer surface, and even if it is included in most of the outer tube, You may have it across. The outer tube is preferably provided with a split portion that is continuous in the axial direction at a part of a cross section of the outer tube.

  The outer tube may be provided outside the shield tube in a compressed state because it can expand and contract in the axial direction. The shield layer may be a plated layer formed on the outer surface of the resin tube. The shield layer may be formed of, for example, a conductive cloth as long as the resin tube is formed by being covered with a conductive member.

  When the outer tube is covered with the shield tube, the ends of the split portions may be covered with each other. The outer tube may be provided with cuts on an outer peripheral surface or an inner peripheral surface at a position facing the split portion.

  According to the first invention, since the outer tube is put on the outer periphery of the resin tube body having the shield layer that is a metal layer, the outer tube is easily colored by coloring the resin itself constituting the outer tube. Can be distinguished. Further, since the resin itself is colored, there is no fear that the coloring is peeled off.

  Moreover, since at least a part of the resin tube has a corrugated shape, it is excellent in flexibility and installation workability. Moreover, since the uneven shape of the inner peripheral surface of the outer tube and the uneven shape of the outer peripheral surface of the resin tube do not fit each other, the outer tube can easily slide with respect to the resin tube (shield tube). . Therefore, when the tube structure is deformed, the flexibility of the outer tube and the resin tube does not deteriorate. In particular, the resin tube and the outer tube are both corrugated tubes, and when the outer tube is covered by making the width of the outer surface of the convex portion of the resin tube larger than the width of the inner surface of the concave portion of the outer tube, It is possible to reliably prevent the outer surface of the convex portion of the resin tube from getting stuck in the inner surface of the concave portion of the outer tube.

  Moreover, since the outer tube has a split portion formed in the axial direction, it is excellent in mountability. It is also possible to cover the outer tube after installing only the inner shield tube. Further, if the shield layer is a plated layer, the flexibility of the resin tube can be ensured reliably, and the installation workability is excellent.

  2nd invention uses the assembly structure of the shield pipe concerning 1st invention, The electric wire penetrated by the said shield pipe, and the terminal part provided in the both ends of the assembly structure of the said shield pipe connected with the said electric wire And a shielded cable structure characterized by comprising:

  Inside the outer tube, a covered wire may be disposed between the outer tube and the outer periphery of the shield tube. At least one of the outer tube and the shield tube may have a substantially rectangular cross section.

  According to the second invention, even if it is used as a high voltage cable, it can be easily distinguished from other cables, it is excellent in handleability, and the shield layer is reliably protected by the outer tube. For example, in the case of a high voltage cable, it is usually colored yellow, but there is no fear that the yellow color will be peeled off.

  A third invention is characterized in that the shielded cable structure according to the second invention is used, and a fixing member is provided in at least a trough portion of the corrugated shape formed on the outer periphery of the outer tube, and is fixed to the structure. This is a method for fixing a shielded cable. When fixing the shielded cable structure to the structure, for example, after sequentially bending according to the fixed layout of the shield cable structure, such as a straight portion or a bent portion, the shield cable structure is sequentially fixed to the structure by a fixing member. It is desirable to do. Here, it is better that the fixing member has not only a function of fixing to the structure but also a function of maintaining the shape of the bent portion.

  According to the third invention, by using a fixing member such as a band or a string member, the fixing member is installed in at least a valley portion of the outer periphery of the shielded cable and fixed to the structure, whereby the shielded cable is attached to the structure. The shielded cable can be securely fixed without shifting.

  According to the present invention, there are provided a shield tube assembly structure, a shield cable structure, and a shield cable fixing method that can be reliably distinguished from other cables, have excellent durability, and handleability such as installation work. Can be provided.

  Hereinafter, a shielded cable 1 according to an embodiment of the present invention will be described. FIG. 1 is a diagram showing a shielded cable 1. The shielded cable 1 mainly includes a shield tube 3, an outer tube 5, a terminal 7, an electric wire 9, and the like.

  The shield tube 3 is composed of a resin corrugated tube having flexibility. A shield layer, which is a metal layer, is formed on at least the outer surface of the shield tube. As the shield layer, for example, metal plating (double structure of electroless plating and electrolytic plating) may be provided on the surface of the resin tube, and at least one layer of metal tape, metal mesh, or the like is provided on the outer periphery of the resin tube. It may be configured to be wound. Anyway, the shield tube 3 should just have flexibility in the state in which the shield layer was formed.

  An electric wire 9 is inserted into the shield tube 3. Both ends of the electric wire 9 which is a covered wire are electrically connected to the terminal 7. The terminal 7 can be connected to, for example, a terminal portion provided in a battery and a motor of an automobile, for example. The terminal shape is appropriately set according to the connection target.

  The outer tube 5 is put on the outer periphery of the shield tube 3. The outer tube 5 is a resin tube having flexibility. The outer tube 5 is formed of a resin colored in advance. For example, a color such as yellow, orange or red that can be distinguished from other resin tubes or metal tubes is applied. It is suitable for use where coloring is required for safety measures.

  2 and 3 are views showing a state in which the outer tube 5 is put on the shield tube 3, FIG. 2 is an exploded perspective view, and FIG. 3 is an assembled perspective view. In FIG. 2 and FIG. As described above, the shield tube 3 is a corrugated tube. The outer tube 5 is a member having a split portion 11 in the axial direction, and becomes a corrugated tube in a closed state (FIG. 3). The outer tube 5 is placed on the outer periphery of the shield tube 3 with the split portion 11 open (FIG. 2), and the shield tube 3 is covered with the outer tube 5 by closing the split portion 11. 1 to 3, an example in which a slight gap is provided in the split part 11 is illustrated, but the split part 11 may be covered so as to be in close contact with each other.

  In addition, a notch 12 is provided on the inner circumferential surface of the opposing portion of the split portion 11. The notch 12 may be formed along the axial direction on the inner peripheral surface side of the outer tube 5, or may be formed along the axial direction on the outer peripheral surface side of the outer tube 5. That is, the outer tube 5 can be easily opened by forming a thin portion on the opposite surface side of the split portion 11 of the outer tube 5.

  FIG. 4 is a view of the outer tube 5 as viewed from the axial direction with the outer periphery of the shield tube 3 being covered. As shown in FIG. 4A, the outer tube 5 may simply contact the end surfaces of the split portion 11 with the outer tube 5 placed on the shield tube 3.

  Moreover, as shown in FIG.4 (b), you may make it the edge parts of the split part 11 of the outer tube 5 mutually overlap in the state which covered the outer tube 5 on the shield tube 3. FIG. For example, a wave-shaped peak part and a valley part may be formed in a trapezoidal shape, and a peak part at one end part may be formed to cover a peak part at the other end part.

  Moreover, as shown in FIG.4 (c), you may make it combine the ends of the split part 11 of the outer tube 5 mutually in the state which covered the outer tube 5 on the shield tube 3. FIG. In this case, an uneven shape, a step, or the like may be formed at both ends of the split portion 11, and the unevenness or the step between the opposing ends may be combined. Further, the step or unevenness may be formed in the axial direction, and the opposing surfaces of the split portions 11 may be combined with the unevenness or step formed in the axial direction.

  The shield tube 3 and the outer tube 5 desirably have a certain degree of heat resistance when used as a shield cable for an automobile. For example, those made of polybutyl terephthalate (PBT) resin can be used. Here, the structure in which the outer tube 5 is covered on the outer periphery of the shield tube 3 is referred to as a shield tube assembly structure.

  FIG. 5 is an enlarged cross-sectional view of a portion A in FIG. As described above, the shield tube 3 is configured by forming the shield layer 15 on the outer surface of the corrugated tube 13. FIG. 5 shows an example in which a shield layer 15 that is a metal plating layer is formed on the corrugated tube 13.

  Here, in the present invention, since the fitting structure between the outer tube and the shield tube is emphasized, the inner surface of the outer tube when viewed from between the outer tube and the shield tube on the inner surface side of the outer tube, The inner surface was described as the convex inner surface. Similarly, regarding the outer surface of the shield tube, the outer surface of the peak portion of the shield tube is expressed as the outer surface of the convex portion, and the outer surface of the valley portion of the shield tube is expressed as the outer surface of the concave portion. Therefore, the concave-convex relationship is reversed between the outer tube and the shield tube in both the mountain and valley portions. Therefore, the inner surface of the outer tube crest is described as the inner surface of the concave portion, the outer surface of the crest of the shield tube facing this is described as the outer surface of the convex portion, the inner surface of the outer tube valley is defined as the inner surface of the convex portion, and the valley of the shield tube facing this. The outer surface of the part is described as the outer surface of the recess. That is, when the outer surface of the crest of the shield tube 3 is a convex outer surface 3a and the inner surface of the crest of the outer tube 5 is a concave inner surface 5b, the width (length in the axial direction) B of the convex outer surface 3a is It is larger than the width (length with respect to the axial direction) C of the opening 5b. Therefore, since the width of the convex outer surface of the shield tube 3 to be fitted into the concave inner surface of the outer tube 5 is longer than the concave inner surface of the outer tube 5, the convex outer surface of the shield tube fits into the concave inner surface of the outer tube 5. There is no.

  Further, when the outer surface of the valley portion of the shield tube 3 is a concave outer surface 3b and the inner surface of the valley portion of the outer tube 5 is a convex inner surface 5a, the width (length in the axial direction) D of the convex inner surface 5a of the outer tube 5 is D. Is larger than the width (length in the axial direction) E of the portion of the opening of the concave outer surface 3b of the shield tube 3. Therefore, since the width of the inner surface of the convex portion of the outer tube 5 that should be fitted into the outer surface of the concave portion of the shield tube 3 is longer than the outer surface of the concave portion of the shield tube 3, the inner surface of the convex portion of the outer tube is fitted into the outer surface of the concave portion of the shield tube. There is no.

  The wave pitches of the shield tube 3 and the outer tube 5 (the pitches of the convex portions or the concave portions in the cross section with respect to the axial direction) may be the same or different. The wave shapes of the shield tube 3 and the outer tube 5 may be the same shape or different shapes. In addition, in order to reliably prevent the fitting of the unevenness, it is sufficient that the width of the top portion of the convex portion described above is larger than the width at the opening portion of the concave portion, and such an effect is substantially rectangular shape (rectangular shape, trapezoidal shape). It is desirable that the wave shape has a side edge at the top as shown in FIG. This is because when the tip of the convex portion has an arc shape, a triangular wave, or the like, the tip of the convex portion may be fitted into a part of the concave portion. Here, if the wave shapes of the wave shapes of the shield tube 3 and the outer tube 5 are different, at least a part of the convex inner surface 5a of the outer tube 5 and the convex outer surface 3a of the shield tube 3 are in contact with each other at a predetermined interval. If the bending of the outer tube 5 and the shield tube 3 is ignored, the convex inner surface 5a does not fit into the concave outer surface 3b, and similarly, the convex outer surface 3a does not fit into the concave inner surface 5b. In this case, for example, even if the wave shape is a sine wave, the unevenness does not fit into each other due to the different wave pitches. Note that the inner surface of the outer tube 5 may be subjected to metal plating or the like to further form a shield layer.

  As described above, according to this embodiment, it is possible to obtain a shielded cable that is excellent in durability and distinguishability and excellent in handling properties such as installation work. In particular, even when the shield layer is formed on the outer surface of the shield tube that is a resin tube body, the outer tube is covered on the outer periphery, so that the shield layer can be prevented from being damaged. In particular, when it is provided at the lower part of an automobile, pebbles or the like do not directly hit the shield layer, and the shield layer can be reliably protected. Therefore, the reliability of the shielding performance is high.

  Moreover, even when it is necessary to distinguish from other cables, such as when used for high voltage, it can be easily visually recognized without coating or the like on the plating layer. At this time, unlike coating, the coating does not peel off due to deterioration with time.

  Further, the shield tube 3 and the outer tube 5 are both corrugated resin tubes and have flexibility. For this reason, when installing the shielded cable in the lower part of the automobile or the like, it is not necessary to perform processing or the like in advance according to the installation route, and can be easily installed on site. Moreover, since the corrugated tube has some elasticity in the length direction, it is excellent in installation workability.

  Further, since the unevenness of the inner surface of the outer tube 5 and the unevenness of the outer surface of the shield tube 3 do not fit each other, even when the outer tube 5 is covered with the shield tube 3, the flexibility of the shield cable is adversely affected. Absent. That is, since the projections and depressions on the outer surface of the shield tube 3 and the projections and depressions on the inner surface of the outer tube 5 do not fit in each other, the shield tube 3 can easily follow the bending of the outer tube 5 at the bent portion. can do.

  In addition, since it becomes the double structure of the shield tube 3 and the outer tube | pipe 5, in order to obtain the intensity | strength requested | required of a shield cable, the thickness of each tubular body can be made thin. That is, since the strength is exhibited by the double structure, the strength of each tubular body can be lowered. For this reason, flexibility can be improved more.

  Moreover, since the split part 11 is formed in the outer pipe 5, it is easy to cover the outer pipe 5 on the shield pipe 3. Moreover, since the split part 11 is formed in the outer tube 5, when the shield cable receives an impact from the outside, the impact can be absorbed by deformation (opening and closing, etc.) of the split part 11. In particular, when a large force is applied from the outside so that the cross-section of the shield cable is flattened, the split portion 11 can be greatly deformed, so that a larger deformation absorbing ability can be obtained, and the shield can be obtained. Cable breakage can be prevented.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, if the outer tube 5 has a corrugated shape and can be expanded and contracted in the axial direction, the outer tube 5 is compressed in the axial direction as shown in FIG. 6 (in the direction of arrow E in the figure). You may cover the shield pipe | tube 15 and may fix the edge part of an axial direction with a terminal. If it does in this way, since the outer pipe | tube 5 will be attached to a terminal in the state which always pressed the terminal, the edge part of an outer pipe | tube will closely_contact | adhere to a terminal. For this reason, it is possible to prevent dust and foreign matter from entering the shielded cable.

  Further, as shown in FIG. 7, a shield tube 20 may be used instead of the shield tube 3. In the shield tube 20 (resin tube), a corrugated portion 21 and a straight tube portion 23 are partially formed. In consideration of the laying form of the shielded cable, the corrugated portion 21 is formed only at a position corresponding to a portion where the shielded cable is bent and arranged. That is, the shielded cable is configured to be bent at the corrugated portion 21 so that the straight tube portion 23 is located at a portion corresponding to the straight portion.

  Even in this state, the irregularities on the outer surface of the corrugated portion 21 and the irregularities on the inner surface of the outer tube 5 are formed in a shape, pitch, or the like that does not fit into each other. Therefore, since the shield tube 20 and the outer tube 5 slide on each other, the flexibility is not adversely affected.

  When the shielded cable is arranged in this manner, it is fixed to the structure to be laid using a fixing member 25 such as a band or a string. The fixing member 25 is disposed so as to fit in at least a valley portion of the outer peripheral surface of the outer tube 5 and is fixed to the structure. Therefore, the fixing member 25 does not shift with respect to the outer tube 5 (shielded cable). For this reason, a shielded cable can be reliably fixed to a structure.

  Moreover, as shown to Fig.8 (a), in addition to the shield pipe | tube 30, you may insert the electric wire 9a which is a covered electric wire inside the outer pipe | tube 5. As shown in FIG. The shield tube 30 is a tubular body having a substantially rectangular (flat shape) shield layer. An electric wire 9 that is a high-voltage electric wire is inserted into the shield tube 30. Since the electric wire 9 is inserted into the shield tube 30, noise from the electric wire 9 is shielded. Therefore, the electric wire 9 a inserted through the gap between the shield tube 30 and the outer tube 5 is not affected by noise from the electric wire 9. The electric wire 9 is a low-voltage electric wire and is a covered electric wire through which a weak current flows such as a low-voltage power system or a signal cable.

  Further, as shown in FIG. 8B, the shape of the outer tube 31 may be substantially rectangular (flat shape) in accordance with the shape of the shield tube 30. That is, the electric wire 9a can be efficiently arranged inside by making at least one of the outer tube and the shield tube into a substantially rectangular shape. Further, by adopting a rectangular shape, installation is easy even in a narrow space under the automobile, and space saving can be achieved. In addition, although only one electric wire 9a inside the outer tube 31 is arranged, a plurality of electric wires can be arranged.

  Thus, by arranging the electric wire 9a inside the outer tube, there is no need to insert the electric wire 9a separately into the protective tube, and the shield tube and the electric wire 9a can be protected only by the outer tube. Therefore, the cable laying space can be reduced.

  Further, as shown in FIGS. 9A and 9B, an electric wire holding portion 33 for holding the electric wire 9a may be formed on the inner peripheral side of the outer tube. The electric wire holding part 33 has a shape corresponding to the electric wire 9a. In addition, the electric wire holding | maintenance part 33 may be formed in any position of the internal peripheral surface of an outer tube | pipe, and is suitably set according to the layout of the electric wire and shield tube in a cross section. Moreover, the shape of the electric wire holding part 33 may be any shape as long as it corresponds to the electric wire 9a. Moreover, the electric wire holding | maintenance part 33 may be formed continuously in the axial direction of an outer tube | pipe, and may be provided at predetermined intervals.

  Moreover, as shown to Fig.10 (a), the outer tube | pipe 41 which does not have a split part can also be used. The outer tube 41 differs from the outer tube 5 only in the presence or absence of a split portion. That is, the outer tube 41 is a flexible resin tube and is formed of a resin colored in advance. Further, the width of the top of the convex portion (outer surface mountain portion) on the outer surface of the shield tube 3 is larger than the inner surface of the concave portion of the outer tube 41 (corresponding to the back surface of the outer surface mountain portion). Accordingly, the convex outer surface of the shield tube 3 does not fit into the concave inner surface of the outer tube 41. As described above, the wave shapes of the wave shapes of the shield tube 3 and the outer tube 41 may be the same or different, and the wave shapes of both may be the same shape or different shapes. .

  When the outer tube 41 is used, the shield tube 3 may be inserted from the end of the outer tube 41. If the shield tube 3 is completely inserted into the outer tube 41, an assembly structure of the shield tube covered with the outer tube 41 on the outer periphery of the shield tube 3 can be obtained (FIG. 10B). The cross-sectional shape of the outer tube 41 may be the same as the example shown in FIG. 4 (except for the split portion and the notch). The outer tube 41 has a substantially rectangular shape as shown in FIGS. It may be inserted at the same time.
