FIG.

  The wire harness 10 includes a plurality of electric wires 12 and a sheet-like electric wire member 30.

  The plurality of electric wires 12 are covered electric wires in which an insulating covering portion 13 is formed around the core wire 14. The core wire is formed of copper, aluminum, a copper alloy, or an aluminum alloy. The core wire may be formed of a single wire, or may be an assembly wire in which a plurality of strands are twisted together. The insulating coating portion 13 is formed of a resin such as polyvinyl chloride, polyethylene, or fluororesin. The electric wire 12 has a role of transmitting various electric signals or electric power. The plurality of electric wires 12 may all have the same outer diameter or may include different outer diameters. At both ends of the electric wire 12, the insulating coating 13 is removed, and the core wire 14 having a predetermined length is exposed.

  Connector terminals 20 are connected to both ends of the electric wire 12. The connector terminal 20 is a member formed by press molding a metal plate or the like, and is formed such that the mating connection portion 22 and the crimping portion 24 are connected in a straight line.

  The mating connector 22 is formed in a cylindrical female terminal shape, a pin-shaped or tab-shaped male terminal shape, or the like.

  The crimping part 24 includes a bottom plate part 25, a pair of core wire crimping pieces 26, and a pair of coated crimping pieces 27.

  The bottom plate portion 25 is formed in an elongated plate shape and extends linearly from one end portion of the counterpart connection portion 22.

  The pair of core wire crimping pieces 26 are plate-like pieces formed so as to extend outward from both side portions of the intermediate portion in the longitudinal direction of the bottom plate portion 25. The pair of coated crimping pieces 27 are plate-like pieces formed so as to extend outward from both side portions of the end portion of the bottom plate portion 25 opposite to the counterpart connection portion 22.

  The exposed core wire 14 is disposed between the pair of core wire crimping pieces 26, and the end portion of the insulating coating portion 13 is disposed between the pair of coated crimping pieces 27 so that the end portion of the electric wire 12 is crimped to the crimping portion. In a state of being disposed on 24, the pair of core wire crimping pieces 26 are crimped and deformed inward, and the pair of coated crimping pieces 27 are crimped and deformed inward. As a result, the pair of core crimping pieces 26 are crimped to the exposed core wire 14, and the pair of covering crimping pieces 27 are crimped to the end portions of the insulating coating portion 13. Is connected. With the configuration in which the pair of core wire crimping pieces 26 are crimped to the core wire 14, the core wire 14 and the connector terminal 20 are electrically and mechanically connected. Moreover, the mechanical connection state of the electric wire 12 and the connector terminal 20 is more reliably maintained by the configuration in which the pair of coated crimping pieces 27 are crimped to the end portions of the insulating coating portion 13.

  The connector terminal 20 is accommodated and held in a cavity of the connector housing 18 formed of resin or the like. In this state, the electric wire 12 connected to the connector terminal 20 extends to the back side of the connector housing 18. When the connector housing 18 is connected to the mating connector housing, the connector terminal 20 and the connector terminal of the mating connector housing are connected. Thereby, the said electric wire 12 is used as a wiring member which transmits an electrical signal or electric power.

  The plurality of electric wires 12 are bundled with their ends aligned.

  The sheet-like electric wire member 30 includes a metal plate 32 and a covering portion 36.

  The metal plate 32 is formed in the shape of a metal plate that can be deformed so as to maintain a cylindrical shape from a flat state. Here, the metal plate 32 is formed of copper, aluminum, a copper alloy, or an aluminum alloy, and includes a metal plate main body portion 33 and an extending piece portion 34. The thickness dimension of the metal plate 32 is set to a thickness dimension that can be plastically deformed so as to be bent and can maintain the bent state in view of the properties of the metal material constituting the metal plate 32.

  The metal plate 32 includes a metal plate main body portion 33 and an extending piece portion 34.

  The metal plate main body 33 is formed in a square plate shape. The length dimension along the extending direction of the pair of opposing sides of the metal plate main body 33 is set to be equal to or smaller than the length dimension between the connector terminals 20 at both ends of the electric wire 12, for example. . This length dimension is preferably set to a size that preferably bundles a plurality of electric wires 12 in a path in which the wire harness 10 is disposed.

  The length dimension along the extending direction of the other set of sides facing each other in the metal plate main body 33 is set to a length dimension that can surround the bundled body in which the plurality of electric wires 12 are bundled. . That is, this length dimension is set to be approximately the same as the circumference of the circumscribed circle of the bundled body in which the plurality of electric wires 12 are bundled.

  The extending piece 34 is formed so as to extend from each of a pair of opposing sides of the metal plate main body 33 in a direction orthogonal to the side. Here, the extending piece part 34 is formed in a rectangular shape, and is formed in the central part in the extending direction of each side.

  The covering portion 36 is formed of a resin such as polyvinyl chloride, polyethylene, or a fluororesin. The covering portion 36 may be molded by using the metal plate 32 as an insert, or may be formed by attaching a sheet-like resin to the metal plate 32. Alternatively, it may be formed by applying a softened and melted resin.

  The covering portion 36 includes a covering main body portion 37 and an extended covering portion 38.

  The covering main body portion 37 covers both sides and the periphery of the metal plate main body portion 33. Here, in a state where the sheet-like electric wire member 30 is bent into a cylindrical shape, a layer located on the outer peripheral side of the covering main body portion 37 is referred to as an outer peripheral side layer 37a, and a layer located on the inner peripheral side is referred to as an inner peripheral side layer 37b. And In this case, it is preferable that the thickness dimension of the outer peripheral side layer 37a is set larger than the thickness dimension of the inner peripheral side layer 37b. In a state where the wire harness 10 is disposed in a vehicle or the like, the outer peripheral layer 37a may be exposed to the outside and come into contact with the vehicle peripheral components. Therefore, by increasing the thickness of the outer peripheral layer 37a, the metal plate 32 is This is because it can be protected.

  The extension covering portion 38 covers both surfaces and both side portions of the proximal end portion of the extension piece portion 34. The extended covering portion 38 is connected to the covering main body portion 37 at the base end portion of the extending piece portion 34.

  The sheet-like electric wire member 30 is rounded into a cylindrical shape so as to accommodate a plurality of electric wires 12 and keep the electric wires 12 in a bundled state. More specifically, the sheet-like electric wire member 30 is arranged such that the outer peripheral side layer 37a is disposed on the outer peripheral side and the inner peripheral side layer 37b is disposed on the inner peripheral side, so that both side edges are abutted. Rounded into a cylindrical shape. The deformation of the sheet-like electric wire member 30 is preferably performed by the operator's human power. At this time, a bundle of a plurality of electric wires 12 is arranged in a sheet-like electric wire member 30 rounded into a cylindrical shape, and the connector terminals 20 at both ends project outside the cylindrical sheet-like electric wire member 30. Let

  And the sheet-like electric wire member 30 itself maintains a cylindrical shape, whereby the plurality of electric wires 12 are maintained in a bundled state in the cylindrical sheet-like electric wire member 30. In addition, an adhesive tape may be wound around the outer periphery of the sheet-like electric wire member 30 in an auxiliary manner.

  The metal plate 32 is connected to the connector terminal 20 at one end in the axial direction of the sheet-like electric wire member 30 bent into the cylindrical shape, and the metal plate 32 is connected to another connector at the other end in the axial direction of the sheet-like electric wire member 30. It is connected to the terminal 20 (see FIGS. 1 and 5). For this reason, the sheet-like electric wire member 30 also has a role of transmitting an electric signal or electric power between the connector terminals 20 similarly to the electric wire 12.

  Here, the connector terminal 20 has the same shape as the connector terminal 20 connected to the electric wire 12, and is connected to the metal plate 32 by the following configuration.

  First, the extension piece portion 34 is formed at the crimped portion 34a rounded. Since the thickness dimension of the extended piece part 34 which is a part of the metal plate 32 that can be easily bent is considered to be smaller than the outer diameter dimension of the core wire 14, the distal end part of the extended piece part 34 is rounded to be bonded part. By forming in 34a, the said to-be-bonded part 34a can be made into the magnitude | size comparable as the outer diameter dimension of the core wire 14. FIG. Thereby, a pair of core wire crimping pieces 26, which are the same as the connector terminals 20 connected to the electric wires 12, can be crimped to the crimped portion 34a.

  The extended covering portion 38 covers a portion of the extended piece portion 34 on the base end side with respect to the pressed portion 34a, and this portion is also rounded. As a result, a portion of the extended piece 34 that is covered with the extended covering portion 38 is processed to have the same size as the outer diameter of the electric wire 12, and a pair of coated crimping pieces of the connector terminal 20 is formed in this portion. 27 can be crimped.

  Here, the part from the base end part to the intermediate part of the extended piece part 34 and the extended covering part 38 is rounded so that the diameter gradually decreases, and the part from the intermediate part to the distal end part forms a cylindrical shape. It is rounded.

  The pair of core wire crimping pieces 26 are crimped to the portion 34a to be crimped, and the pair of coated crimping pieces 27 are crimped to the extended covering portion 38, so that the same connector terminal as the connector terminal 20 connected to the electric wire 12 is obtained. 20 can be connected to the metal plate 32.

  Depending on the thickness dimension or the like of the metal plate 32, for example, when the thickness dimension of the metal plate 32 is approximately the same as the outer dimension of the core wire 14, the extension piece 34 or the like can be extended without rounding. The connector terminal 20 can be crimped to the piece 34.

  Moreover, it is not essential to connect the same thing as the connector terminal 20 connected to the electric wire 12 with the said connection structure to the metal plate 32. FIG. For this reason, one or both of the two extended piece portions 34 and the extended covering portion 38 may be omitted. For example, one end of another relay wire may be soldered to the exposed portion of the metal plate, and the other end may be connected to the connector terminal. Moreover, you may use the connector terminal with a press contact blade which cuts into a coating | coated part and press-contacts to an internal metal plate.

  As described above, the connector terminal 20 is connected to the plurality of electric wires 12 in the state where the connector terminal 20 is connected to the extended piece portion 34 and the extended covering portion 38 at each of the axial end portions of the sheet-like electric wire member 30. Are arranged at positions aligned with the connector terminal 20 connected to the end of the connector. And in each of the axial direction both ends of the sheet-like electric wire member 30, the some connector terminal 20 is inserted in the cavity of the connector housing 18 which is common.

  Moreover, since the said sheet-like electric wire member 30 can be deform | transformed so that it may wind around the outer peripheral side in the state which wired the some electric wire 12 on the wire harness assembly drawing board etc., mounting | wearing of the sheet-like electric wire member 30 Can be easily performed.

  Each connector housing 18 is connected to the mating connector housing so that the connector terminal 20 is connected to the mating connector terminal. Thereby, this wire harness 10 is used as a wiring member which transmits an electric signal and electric power between various electric components in a vehicle etc.

  A part of the electric wires 12 may be branched from the other electric wires 12 on the outer side of the axial end portion of the sheet-like electric wire member 30 and connected to other electric components.

  According to the wire harness 10 and the sheet-like electric wire member 30 configured as described above, the sheet-like electric wire member 30 includes the metal plate 32 and the covering portion 36 that covers the metal plate 32, and therefore transmits an electric signal or electric power. It can be used as a wiring member. Then, the sheet-like wire member 30 can be rolled from a flat state into a cylindrical shape, and the plurality of wires 12 can be accommodated therein and the plurality of wires 12 can be bundled. That is, the sheet-like electric wire member 30 can have a function of bundling a plurality of electric wires 12.

  Moreover, since the metal plate 32 is connected to the connector terminal 20 at both axial ends of the cylindrical sheet-like electric wire member 30, the sheet-like electric wire member 30 is used as a wiring member for connecting the two connector terminals 20 to each other. Can be used.

  Further, by rounding the tip end portion of the extended piece portion 34 extending from the metal plate main body portion 33 of the metal plate 32 to be a pressure-bonded portion 34a, and crimping the pair of core wire crimping pieces 26 of the connector terminal 20 to this, The connector terminal 20 can be easily crimped to the extending piece 34 to connect the metal plate 32 and the connector terminal 20.

  Thereby, for example, the same shape as the connector terminal 20 to be crimped to the core wire 14 of the electric wire 12 can be crimped and connected to the metal plate 32.

  Further, the covering portion 36 includes an extending covering portion 38 that covers a portion of the extending piece portion 34 that is closer to the base end side than the crimped portion 34a, and the pair of covering crimping pieces 27 of the connector terminal 20 are extended covering portions. Since the connector terminal 20 is crimped to the core wire 14 and the insulation coating portion 13 of the electric wire 12, it can be crimped and connected to the sheet-like electric wire member 30. And connector terminal 20 and sheet-like electric wire member 30 can be connected with sufficient intensity.

  In addition, the connector terminal 20 does not necessarily need to be provided with the part crimped | bonded to the insulation coating part 13. As shown in FIG.

  Moreover, the outer peripheral side layer 37a of the sheet-like electric wire member 30 is thicker than the inner peripheral side layer 37b. For this reason, the metal plate 32 can be protected by the relatively thick outer peripheral layer 37a. The plurality of electric wires 12 inside the sheet-like electric wire member 30 are protected by the sheet-like electric wire member 30.

{Modifications}
In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
