Description

  The present invention relates to a conductor and a method for manufacturing the conductor.

Conventionally, the thing of patent document 1 is known as a conductor. This is mounted on, for example, an electric vehicle or a hybrid vehicle, and electrically connects a battery, an inverter, a motor, or the like. The above conductor is formed by housing an electric wire in a metal pipe. Thereby, an electric wire can be protected from the collision of a foreign material.
JP 2004-171952 A

  In the conductor according to the above configuration, the heat generated from the electric wire during energization is transmitted from the electric wire to the pipe and is dissipated from the pipe to the outside of the electric conductor. However, according to said structure, an air layer exists between an electric wire and a pipe. Since this air layer has a relatively low thermal conductivity, there is a concern that heat is trapped inside the pipe and the electric wire becomes hot.

  When an upper limit is set for the temperature rise value of the electric wire, it is conceivable to reduce the amount of heat generated during energization by increasing the diameter of the electric wire. However, this method cannot be adopted because the entire conductor is enlarged.

  In order to solve the above problems, a plurality of plate members in which grooves for accommodating electric wires are formed are combined to form a sheath tube, and the inner peripheral surface of the sheath tube and the outer peripheral surface of the electric wire are brought into close contact with each other Can be considered. With the above configuration, the heat generated in the electric wire is directly transmitted to the sheath tube, so that the heat can be prevented from being trapped between the electric wire and the sheath tube.

  However, there is a concern that the manufacturing cost increases when the work of combining the plate materials is performed. For example, it is conceivable that the plate materials are united by welding the flange portions formed so as to protrude outward from both sides of the groove and extend along the direction in which the electric wire extends. However, since a welding machine for welding the flanges is required, there is a concern that the manufacturing cost increases.

  In addition, although it is conceivable to bond the collars together, there is a concern that the manufacturing cost will increase because the curing time of the adhesive is required.

  The present invention has been completed based on the above situation, and an object thereof is to provide a conductor with reduced manufacturing cost.

  The present invention is a conductor provided with an electric wire and a sheath tube that accommodates the electric wire, the outer peripheral surface of the electric wire and the inner peripheral surface of the sheath tube are in close contact, A plurality of plate members having a groove for accommodating the electric wire are combined, and the plate member is formed with a pair of flanges protruding outward from both side edges of the groove, and the plate members are connected to each other. The clamps having a pair of sandwiching walls that are elastically deformable in the expanding direction are externally fitted between the flange portions that are in contact with each other. In this case, the plate members are combined with each other by sandwiching the flanges.

  According to the present invention, the sheath tube can be manufactured by a simple method in which the clamp is externally fitted to the flanges brought into contact with each other. Thereby, since the apparatus for uniting plate materials, such as a welding machine, becomes unnecessary, manufacturing cost can be reduced.

As embodiments of the present invention, the following embodiments are preferable.
A lock portion is formed on the outer surface of the flange portion in a state where the flange portions of the pair of plate materials are in contact with each other, and the clamp wall of the clamp has the flange in a position corresponding to the lock portion. The lock receiving part engaged from the back of the fitting direction of the said clamp with respect to the part may be formed.

  According to said structure, when a lock receiving part engages with the lock part from the back of the fitting direction of the clamp with respect to a collar part, it is controlled that a clamp moves to the direction which detach | leaves from a collar part. The As a result, it is possible to prevent the clamp from coming off.

  The collar part may be formed to extend over substantially the entire length of the plate member, and the clamp may be fitted over the collar part over the substantially entire length of the collar part.

  According to said structure, since the collar part formed over the substantially full length of the board | plate material is externally fitted by the clamp over the substantially whole length of the collar part, board | plate materials can be united reliably.

  It should be noted that “over the entire length of the plate material” includes a case where the plate material extends over the entire length, and includes a case where the entire length of the plate material can be substantially identified even if it does not extend over the entire length of the plate material. Moreover, while covering the substantially full length of a collar part, while including the case where it extends over the full length of a collar part, the case where it can substantially equate over the full length is included even if it does not extend over the full length of a collar part.

  A plurality of the clamps may be externally fitted to the collar portion at intervals in the extending direction of the electric wire.

  According to said structure, the force required when fitting a clamp to a collar part can be reduced.

  The electric wire may include a core wire, an insulating coating that surrounds the outer periphery of the core wire, and a braided wire that surrounds the outer periphery of the insulating coating.

  According to said structure, the electromagnetic waves generated from an electric wire can be shielded.

  Further, the present invention is a method for manufacturing a conductor including an electric wire and a sheath tube that accommodates the electric wire, and has a groove that accommodates the electric wire and protrudes outward from both side edges of the groove. A step of housing the electric wire in the groove of the plate member having a portion, and an outer peripheral surface of the electric wire and an inner peripheral surface of the groove are brought into close contact with the plate member in which the electric wire is accommodated And a step of assembling in a posture in which the flanges are brought into contact with each other, and a step of externally fitting a clamp having a pair of holding walls that are elastically deformable in the expanding direction with respect to the flanges that are in contact with each other. Execute.

As embodiments of the present invention, the following embodiments are preferable.
A step of attaching a plurality of the clamps to the mounting portion of the holding member formed with a plurality of mounting portions capable of holding the clamp at an interval; and the clamp in the state of being held by the holding member It is good also as a mode which performs the process of fitting outside.

  According to the above method, the plurality of clamps can be held by the holding member. Thereby, when storing a some clamp, it can suppress that a clamp dissipates. Moreover, since a clamp can be externally fitted to a collar part in the state with which the holding member was mounted | worn, work efficiency can be improved compared with the case where a clamp is fitted one by one.

  The mounting portion is configured to detachably hold the clamp, and after the clamp is fitted on the flange portion, a step of detaching the holding member from the clamp may be performed.

  According to the above method, the holding member can be reused by detaching the holding member from the clamp after the clamp is fitted on the collar.

  According to the present invention, the manufacturing cost of the conductor can be reduced.

The outer peripheral surface of the core wire 13 and the inner peripheral surface of the insulating coating 14 are in close contact.

  The braided wire 15 has a cylindrical shape as a whole. The braided wire 15 is formed by braiding metal fine wires in a mesh shape. The braided wire 15 can be expanded and contracted in the radial direction and expanded and contracted in the length direction due to the flexibility of the fine metal wires. The outer peripheral surface of the insulating coating 14 of the electric wire 12 and the inner peripheral surface of the braided wire 15 are in close contact.

(Sheath tube 11)
As shown in FIG. 1, the sheath tube 11 includes a first plate 16 made of synthetic resin (corresponding to the plate of the present invention) located on the left side in FIG. 1 and a second plate 17 made of synthetic resin located on the right side ( Equivalent to the plate material of the present invention). The first plate member 16 and the second plate member 17 have the same shape, and the first plate member 16 and the second plate member 17 are halved. As the synthetic resin, a relatively rigid material such as polyethylene, polypropylene, PET, PBT, or nylon can be used. The sheath tube 11 is formed to extend in a direction penetrating the paper surface in FIG.

  In the first plate member 16 and the second plate member 17, a groove 18 having a semicircular cross section is formed so as to extend in a direction in which the electric wire 12 extends (a direction penetrating the paper surface in FIG. 1). By combining the first plate member 16 and the second plate member 17, a space having a circular cross section is formed by the groove 18 of the first plate member 16 and the groove 18 of the second plate member 17. This space is an electric wire housing portion 19 for housing the electric wires 12. The inner diameter of the inner peripheral surface of the electric wire housing part 19 is set to be the same as or slightly smaller than the outer diameter of the electric wire 12 (including the braided wire 15). Thereby, the outer peripheral surface of the braided wire 15 of the electric wire 12 and the inner peripheral surface of the electric wire housing part 19 of the sheath tube 11 are brought into close contact with each other.

  As shown in FIG. 1, the first plate member 16 and the second plate member 17 are formed with a pair of flange portions 20 that protrude outward (up and down direction in FIG. 1) from the upper and lower side edges of the groove 18 in FIG. 1. ing. The flange portion 20 is formed so as to extend in a direction in which the electric wire 12 extends (a direction that penetrates the paper surface in FIG. 1). As shown in FIG. 7, the flange 20 extends over the entire length of the first plate member 16 and the second plate member 17 along the direction in which the first plate member 16 and the second plate member 17 extend (the direction in which the electric wires 12 extend). Is formed.

  The sheath tube 11 is formed by bringing the flange portion 20 of the first plate member 16 and the flange portion 20 of the second plate member 17 into contact with each other and combining them.

(Clamp 21)
As shown in FIG. 1, in a state where the flange portion 20 of the first plate member 16 is in contact with the flange portion 20 of the second plate member 17, metal clamps 21 are provided on both flange portions 20. The outer side of 20 is externally fitted so that it may be pinched | interposed collectively. As shown in FIG. 7, the clamp 21 is formed to have substantially the same length as the length of the sheath tube 11.

  As shown in FIG. 1, the clamp 21 has a pair of sandwiching walls 22 that face each other and can be elastically deformed in the expanding direction, and a connecting wall 23 that connects the sandwiching walls 22. The first plate member 16 and the second plate member 17 are fixed by sandwiching the two flange portions 20 described above between the pair of holding walls 22. When the flange portion 20 is clamped by the clamping wall 22 of the clamp 21, the inner peripheral wall of the sheath tube 11 is pressed inward and comes into close contact with the outer peripheral surface of the braided wire 15. Furthermore, when the braided wire 15 is pressed against the inner peripheral wall of the sheath tube 11, the inner peripheral surface of the braid 15 comes into close contact with the outer peripheral surface of the insulating coating 14.

  As shown in FIG. 2, the opening end portions (lower end portions in FIG. 2) of the pair of sandwiching walls 22 are bent in the direction of expanding each other, and when fitted to the flange portion 20, the flange portion 20. Has been invited.

  The flange portion 20 of the first plate member 16 and the flange portion 20 of the second plate member 17 are formed with a lock portion 24 that protrudes outward on the side surface located on the outer side in a state where both the flange portions 20 are in contact with each other. Has been. Of the lock portion 24, the side surfaces on the edge sides of the both flange portions 20 are formed so as to be inclined relatively gently. On the other hand, the side surface of the lock portion 24 opposite to the end edges of the both flange portions 20 is formed to be relatively sharp. Further, the holding wall 22 has a lock receiving portion 25 that elastically engages with the lock portion 24 at a position corresponding to the lock portion 24 in a state in which the holding wall 22 is externally fitted to the both flange portions 20. Is formed. The shape of the lock receiving portion 25 is formed following the shape of the lock portion 24. In a state where the clamp 21 is externally fitted to the flange portion 20, the lock portion 24 and the lock receiving portion 25 are engaged, and the clamp 21 is prevented from coming off. As shown in FIG. 9, the clamp 21 is fitted over the entire length of the flange 20.

  As shown in FIG. 2, a fulcrum portion 26 that bulges outward in the thickness direction of the connecting wall 23 is formed on the connecting wall 23 at a substantially central position between the pair of holding walls 22. With the fulcrum portion 26 as the center, the connecting wall 23 itself can be elastically bent and deformed. Thereby, it becomes easy for a pair of clamping wall 22 to deform | transform into an expansion direction mutually (refer FIG. 3).

  Then, an example of the manufacturing process of the conductor 10 which concerns on this embodiment is shown. First, the 1st board | plate material 16 and the 2nd board | plate material 17 are formed by shape | molding a synthetic resin material. Both plate members 16 and 17 can be formed by a known method such as injection molding or extrusion molding.

  As shown in FIG. 5, the electric wire 12 is accommodated in one of the grooves 18 of the first plate member 16 and the second plate member 17. In FIG. 5, the electric wire 12 is accommodated in the groove 18 of the second plate member 17. Next, as shown in FIG. 6, the flange portions 20 of the two plate members 16 and 17 are brought into contact with each other in a posture in which the groove 18 of the other plate member (the first plate member 16 in FIG. 6) is directed to the electric wire 12 side.

  Subsequently, as shown in FIG. 2 and FIG. 7, the clamp 21 is externally fitted from the edge side of the flange 20 to the flange 20 that abuts each other. When the clamp 21 is moved to the flange 20 side, the end edge of the clamping wall 22 comes into contact with the outer surface of the flange 20. At this time, the flange portion 20 is guided between the sandwiching walls 22 by the opening edge of the sandwiching wall 22 that is bent in the expanding direction.

  When the clamp 21 is further moved, as shown in FIG. 2, the sandwiching walls 22 are elastically deformed in the expanding direction, and the connecting wall 23 is elastically deformed around the fulcrum portion 26. By this fulcrum portion 26, the holding wall 22 can be easily elastically deformed in the expanding direction.

  Thereafter, the lock receiving portion 25 of the clamping wall 22 rides on the lock portion 24. Thereby, as above-mentioned, the connection wall 23 and the clamping wall 22 deform | transform elastically (refer FIG. 3). When the clamp 21 is further moved, the connecting wall 23 and the clamping wall 22 are restored and deformed, and the lock receiving portion 25 is engaged with the lock portion 24 from the rear in the fitting direction of the clamp 21. As a result, the clamp 21 is prevented from coming off (see FIGS. 4 and 9).

  As shown in FIG. 8, when the clamp 21 is externally fitted to the flange portion 20, one end portion in the longitudinal direction of the clamp 21 is externally fitted to the flange portion 20 before the other end portion. Thus, the force when fitting the clamp 21 may be reduced.

  As shown in FIG. 1, clamps 21 are externally fitted to the pair of flange portions 20 formed on both side edges of the first plate member 16 and the second plate member 17 by the same method as described above. Thereby, the 1st board | plate material 16 and the 2nd board | plate material 17 are fixed in the state which made the collar parts 20 contact | abut. Thereby, the conductor 10 is completed.

  Then, the effect | action and effect of this embodiment are demonstrated. According to the present embodiment, the sheath tube 11 can be manufactured by a simple method in which the clamps 21 are externally fitted to the flange portions 20 that are brought into contact with each other. This eliminates the need for a device such as a welding machine for combining the plate materials, and also eliminates the need for an adhesive drying step, thereby reducing the manufacturing cost.

  Further, according to the present embodiment, the lock 21 is engaged with the lock portion 24 from the rear in the fitting direction of the clamp 21 with respect to the flange portion 20, whereby the clamp 21 is detached from the flange portion 20. Movement in the direction is restricted. Thereby, the clamp 21 can be prevented from coming off.

  Moreover, according to this embodiment, since the collar part 20 formed over the full length of the board | plate material is fitted by the clamp 21 over the full length of the collar part 20, the 1st board | plate material 16 and the 2nd board | plate material 17 Can be reliably combined.

  In addition, according to the present embodiment, the electric wire 12 includes the core wire 13, the insulating coating 14 surrounding the outer periphery of the core wire 13, and the braided wire 15 surrounding the outer periphery of the insulating coating 14. The braided wire 15 can shield electromagnetic waves generated from the electric wire 12.

<Embodiment 2>

As shown in FIG. 10, in this embodiment, the length dimension of the clamp 31 in the direction along the wall surface of the sandwiching wall 22 is set shorter than the length dimension of the flange portion 20 in the longitudinal direction. A plurality of clamps 31 are externally fitted to the flange portions 20 of the first plate member 16 and the second plate member 17 with an interval in the direction in which the first plate member 16 and the second plate member 17 extend (the direction in which the electric wires 12 extend). Yes.

  As shown in FIG. 11, the clamp 31 is stored or transported while being held by a holding member 30 formed by bending a metal bar. The holding member 30 is elastically deformable. A plurality of mounting portions 32 to which the clamps 31 are mounted are formed on the holding member 30 at intervals in the direction in which the holding member 30 extends. In the present embodiment, the mounting portion 32 is formed with a constant pitch interval.

  As shown in FIG. 12, the mounting portion 32 is formed by projecting the holding member 30 in one direction (upward in FIG. 12) and bending it. The mounting portion 32 is formed with a narrow portion 33 which is narrower than the length dimension of the connecting wall 23 of the clamp 31 in the direction along the wall surface of the holding wall 22 (left and right direction in FIG. 12). Yes.

  As shown in FIG. 13, the clamp 31 is assembled to the mounting portion 32 from the direction opposite to the protruding direction of the mounting portion 32 (downward in FIG. 13) with respect to the holding member 30. When the clamp 31 is moved to the holding member 30 side, the edge of the fulcrum portion 26 formed on the connecting wall 23 of the clamp 31 and the narrow portion 33 of the holding member 30 come into contact with each other. Then, the mounting portion 32 is elastically expanded and deformed. When the clamp 31 is further moved, the mounting portion 32 is restored and deformed, and the fulcrum portion 26 of the clamp 31 is held by the narrow portion 33 (see FIG. 12).

  Since the configuration other than the above is substantially the same as that of the first embodiment, the same members are denoted by the same reference numerals, and redundant description is omitted.

  Then, an example of the manufacturing process of this embodiment is demonstrated. As shown in FIG. 13, the clamp 31 is assembled to the mounting portion 32 from the direction opposite to the protruding direction of the mounting portion 32 (downward in FIG. 13) with respect to the holding member 30. When the clamp 31 is moved to the holding member 30 side, the edge of the fulcrum portion 26 formed on the connecting wall 23 of the clamp 31 and the narrow portion 33 of the holding member 30 come into contact with each other. Then, the mounting portion 32 is elastically expanded and deformed. When the clamp 31 is further moved, the mounting portion 32 is restored and deformed, and the fulcrum portion 26 of the clamp 31 is held by the narrow portion 33 (see FIG. 12).

  As shown in FIG. 11, the holding member 30 and the clamp 31 are stored and transported in a state where the clamp 31 is mounted on the mounting portion 32.

  In the same manner as in the first embodiment, the electric wires 12 are accommodated in one of the grooves 18 of the first plate member 16 and the second plate member 17, and the two plate members 16, with the other groove 18 directed toward the electric wire 12 side, The 17 flange parts 20 are brought into contact with each other.

  Next, the clamps 31 held by the holding member 30 are externally fitted to the flange portions 20 that are in contact with each other from the edge side of the flange portions 20.

  After the clamp 31 is fitted on the flange portion 20, as shown in FIG. 14, the holding member 30 is pulled away from the sheath tube 11. Then, the narrow portion 33 of the mounting portion 32 is expanded and deformed by being pressed against the end edge of the fulcrum portion 26 of the clamp 31. Thereby, the mounting portion 32 is detached from the clamp 31. All the mounting portions 32 are detached from the clamp 31 to complete the conductor 40 (see FIG. 10).

  Next, functions and effects of this embodiment will be described. According to the present embodiment, a plurality of clamps 31 are externally fitted to the collar portion 20 with a gap therebetween. Thereby, the force required when fitting the clamp 31 to the collar part 20 can be reduced.

Further, according to the present embodiment, the plurality of clamps 31 can be held by the holding member 30. Thereby, when the several clamp 31 is stored or conveyed, it can suppress that the clamp 31 dissipates.
Moreover, since the clamp 31 can be externally fitted to the flange portion 20 while being attached to the holding member 30, the working efficiency can be improved as compared with the case where the clamps 31 are fitted one by one.

  Further, according to the present embodiment, the holding member 30 can be reused by detaching the holding member 30 from the clamp 31 after the clamp 31 is externally fitted to the flange portion 20.
