{Embodiment}
Hereinafter, the electric wire module 10 which concerns on embodiment is demonstrated. Drawing 1 is a partial notch perspective view showing electric wire module 10 concerning an embodiment. 2 is a schematic cross-sectional view taken along line II-II in FIG.

  The electric wire module 10 according to the embodiment includes a plurality of electric wires with terminals 12, an exterior member 20, and a connector housing 40. The electric wire module 10 according to the embodiment is a member for collectively inserting the terminals 16 of the plurality of electric wires 12 with terminals into the terminal accommodating chamber 46 of the connector housing 40.

<Wire 12 with terminal>
The plurality of electric wires with terminals 12 are members for electrically connecting a plurality of electronic devices. Specifically, the terminal-attached electric wire 12 includes an insulated wire 14 and a terminal 16 that is crimped to an end portion of the insulated wire 14. And it connects by inserting the terminal 16 part of the electric wire 12 with a terminal with respect to the terminal accommodating chamber 46 formed in the connector housing 40 (including connector housing parts, such as a junction box and a relay box).

  The insulated wire 14 includes a core wire formed of copper (including a copper alloy) or aluminum (including an aluminum alloy), and an insulating coating formed of an insulating resin that covers the core wire.

  The terminal 16 includes a core wire barrel portion that is crimped and crimped to a core wire extending from the end of the insulating coating, and a coating barrel portion that is crimped and crimped to the end portion of the insulating coating at the end portion of the terminal-attached electric wire 12. Can be used. Moreover, the terminal 16 is provided with the contact part electrically connected with the corresponding other party terminal in the front-end | tip part. The mating terminal contacts the end of the contact portion inserted into the terminal accommodating chamber 46 at the back of the terminal accommodating chamber 46. The mating terminal is a conductive member that mediates electrical connection between various devices or electrical components mounted in the vehicle and the insulated wire 14, for example.

<Connector housing 40>
The connector housing 40 is formed with a plurality of terminal accommodating chambers 46 into which the terminals 16 of the plurality of electric wires 12 with terminals are respectively inserted.

  Specifically, the connector housing 40 is a non-conductive member formed using, for example, a resin material. The connector housing 40 includes a frame body 42 that forms an outer peripheral portion thereof, and a terminal housing chamber forming body 44 that is disposed inside the frame body 42 and forms a plurality of terminal housing chambers 46. The terminal accommodating chamber forming body 44 forms a partition that divides the space in the frame 42 into a plurality of terminal accommodating chambers 46. The terminal accommodating chamber forming body 44 and the frame body 42 may be integrally molded or may be separate. The terminal accommodating chamber 46 constitutes a terminal accommodating chamber into which the terminal 16 in the terminal-attached electric wire 12 is inserted.

  Here, the terminal accommodating chamber 46 is formed so that the end on the side where the terminal 16 is inserted is slightly larger than the end on the opposite side. Thereby, the tip end portion of the terminal 16 can easily enter the terminal accommodating chamber 46.

  The inner wall portion of the terminal accommodating chamber 46 is provided with a locking portion (not shown) for locking and fixing the terminal 16 portion of the terminal-attached electric wire 12. When a part of the terminal 16 (for example, the rear end portion of the contact portion) of the terminal-attached electric wire 12 accommodated in each terminal accommodating chamber 46 is caught by this engaging portion, the rear disconnection of the terminal-attached electric wire 12 is suppressed. Of course, it is also possible to suppress the trailing-out of the terminal-attached electric wire 12 by other mechanisms.

<Exterior member 20>
The exterior member 20 includes a plurality of plate-like members 22 and at least one interposed member 24.

  Here, the plate-like member 22 and the interposition member 24 are formed of resin. But the material which forms the plate-shaped member 22 and the interposition member 24 is not specifically limited. The plate-like member 22 and the interposition member 24 may be formed of paper, may be formed of resin, or may be configured by a combination thereof.

  In the case where the plate-like member 22 and the interposition member 24 are formed of paper, and will be described later, when the plate-like member 22 and the interposition member 24 are arranged in the vehicle as they are attached to the terminal-attached electric wires 12, the plate-like member 22 The interposition member 24 is preferably subjected to water repellent treatment or the like.

  Moreover, the plate-shaped member 22 and the interposition member 24 may be formed with the same material, and may be formed with another material. When the plate-like member 22 and the interposition member 24 are formed of the same material, for example, the exterior member 20 can be easily formed by integrally forming by extrusion as in an exterior member 20D according to a fourth modification described later. Can do.

  The plate-like member 22 is formed in a thin plate shape. The plurality of plate-like members 22 are provided so as to face each other with a gap therebetween. Specifically, here, the pair of plate-like members 22 are provided so as to face each other in a state where their main surfaces are parallel to each other.

  The interposition member 24 is provided so as to partition a space between at least one end side of the plurality of plate-like members 22. The interposition member 24 is provided in a space between the plurality of plate-like members 22 so as to form a plurality of openings 28 arranged at a constant pitch and an accommodation space 29 that can accommodate the electric wires. One of the pitch of the plurality of openings 28 partitioned by the interposition member 24 and the pitch of the plurality of terminal accommodating chambers 46 is formed to be an integral multiple of the other.

  Specifically, the intervening member 24 is a member formed in a plate shape having an uneven shape here. The interposition member 24 is joined to the inward surface of the plate-like member 22 while being sandwiched between the pair of plate-like members 22. The plate member 22 and the interposition member 24 are joined by, for example, an adhesive or a pressure sensitive adhesive. Thereby, the opening part 28 according to the uneven | corrugated shape which the interposition member 24 exhibits is formed between a pair of plate-shaped members 22. FIG.

  More specifically, here, the interposition member 24 is formed in a shape in which a crest 26 and a trough 27 are continuous in a wave shape. The extending direction of the peak portion 26 and the extending direction of the valley portion 27 are in a parallel positional relationship. Therefore, when the interposition member 24 is viewed in plan, the plurality of peak portions 26 and the plurality of valley portions 27 are alternately formed in parallel. The top part of the peak part 26 and the bottom part of the valley part 27 may be curved, or may be bent at a predetermined angle.

  And the interposition member 24 is inserted | pinched between a pair of plate-shaped members 22, and the bottom surface of the bottom part of the trough part 27 and the inward surface of the lower plate-shaped member 22 are joined, and the top part of the peak part 26 is joined. The upper surface and the inward surface of the upper plate-like member 22 are joined. Thereby, a plurality of openings 28 are formed at both ends in the space between the pair of plate-like members 22. That is, here, the space surrounded from the one end side to the other end side of the plate-like member 22 by the inner peripheral surface of the interposition member 24 and the plate-like member 22 is the accommodation space 29. The part is an opening 28. And the insulated wire 14 part of the some electric wire 12 with a terminal 12 is each accommodated in the accommodation space 29 in the aspect in which the terminal 16 is exposed outside from the some opening part 28, respectively.

  The openings 28 at both ends and the accommodation space 29 between them can be regarded as holes in one cylindrical portion that is open at both ends. Thus, if the circumference | surroundings of the accommodation space 29 which connects the opening part 28 of both ends are completely enclosed, it can suppress that the electric wires 12 with a terminal 12 accommodated in each accommodation space 29 are entangled.

  Further, here, the terminal-attached electric wire 12 is fixed at a fixed position in the accommodating space 29 along the extending direction. Specifically, here, after the terminal-attached electric wire 12 is accommodated in the accommodating space 29, the adhesive 50 is poured from the opening 28 to insulate the accommodating space 29 near the opening 28 by the adhesive 50. The electric wire 14 portion is fixed to the exterior member 20. Thereby, when inserting the terminal 16 into the terminal accommodating chamber 46, the electric wire 12 with a terminal becomes difficult to shift in the extending direction. Further, the terminal is held so as to have a constant posture around the axis of the electric wire with terminal.

  But it is not essential for the electric wire 12 with a terminal to be fixed to the fixed position along the extension direction in the accommodation space 29. FIG. Moreover, even if it is a case where it fixes, it is not essential to fix with the adhesive agent 50. FIG. For example, the housing space 29 is formed so that the size thereof is reduced at the intermediate position and the intermediate portion of the terminal-attached electric wire 12 can be clamped, so that the terminal-attached electric wire 12 and the exterior member can be separated by frictional force or tightening force. May be detachably fixed.

  Further, here, the exterior member 20 holds the terminal-attached electric wire 12 so that the terminal 16 is in a fixed posture around the axis of the terminal-attached electric wire 12. Specifically, the insulated wire 14 is fixed to the exterior member 20 in the vicinity of the opening 28 in the accommodation space 29 by the adhesive 50, so that the axial displacement of the terminal-attached wire 12 relative to the exterior member 20 is achieved. In addition, rotation around the axis is also suppressed. Thereby, the terminal 16 of the electric wire 12 with a terminal is hold | maintained in the fixed attitude | position around an axis | shaft. More specifically, here, the terminal 16 is maintained in a posture in which the direction of the terminal 16 around the axis of the terminal-attached electric wire 12 coincides with the direction of insertion into the terminal accommodating chamber 46.

  However, it is not essential that the exterior member 20 holds the electric wire 12 with a terminal so that the terminal 16 is in a fixed posture around the axis of the electric wire 12 with a terminal. Even when the exterior member 20 holds the terminal-attached electric wire 12 so that the terminal 16 is in a constant posture around the axis of the terminal-attached electric wire 12, the holding method may not be the adhesive 50. As described above, the housing space 29 has a size that is small at the intermediate position, and is formed so as to be able to sandwich the intermediate portion of the terminal-attached electric wire 12. The terminal 16 may be held so as to be in a fixed posture without rotating around the axis with respect to the exterior member.

  In addition, although the edge part of the plate-shaped member 22 and the edge part of the interposition member 24 are formed here, you may form so that either one may protrude a little. For example, the terminal 16 can be sandwiched between the plurality of plate-like members 22 by slightly projecting the end of the plate-like member 22 from the end of the interposed member 24.

  Moreover, it is not essential that the terminal-attached electric wires 12 extend from all of the plurality of openings 28, and the terminal-attached electric wires 12 selectively extend from the openings 28 according to the position of the terminal housing chamber 46 of the connector housing 40. It only has to be done.

  The pitch of the openings 28 is determined by the thickness of the interposition member 24 and the interval between the peaks 26 (or valleys 27). Here, the pitch of the openings 28 is formed to be equal to the pitch of the terminal accommodating chambers 46 of the connector housing 40. Thereby, the pitch of the terminals 16 can be adjusted to the pitch of the terminal accommodating chamber 46 in a state where the end of the terminal-attached electric wire 12 is extended from the opening 28.

  A plurality of types of connector housings are used for automobile wiring members. For example, the pitch of the terminal accommodating chambers is set to be an integral multiple between the plurality of types of connector housings, and the pitch of the openings 28 of the exterior member 20 is made smaller than the pitch of the plurality of types of connector housings. Thus, one type of exterior member 20 can correspond to a plurality of types of connector housings.

  A manufacturing example of such an exterior member 20 will be described.

  The interposition member 24 can be formed, for example, by sandwiching a flat plate member between press dies having an uneven surface. For example, a flat plate-like member having a belt shape is continuously supplied along a predetermined conveyance path, and a pair of rollers is disposed along the conveyance path. An uneven shape is formed on the surface of the pair of rollers. Then, the intermediate member 24 is continuously formed by continuously sandwiching the flat plate-like member with a pair of rollers while conveying the flat plate-like member having a belt shape along a predetermined conveyance path. Can do.

  A pair of belt-like plate members 22 are continuously supplied along the conveying path to the downstream side of the pair of rollers, and the interposition members 24 are sequentially placed between the pair of belt-like plate members 22. It is sandwiched and joined with an adhesive. Thereby, the exterior member 20 can be manufactured continuously.

<Insert method>
Next, a method for inserting the terminal 16 into the terminal accommodating chamber 46 using the electric wire module 10 will be described. 3 to 5 are schematic plan views for explaining a process of inserting the terminal 16 of the terminal-attached electric wire 12 accommodated in the exterior member 20 into the terminal accommodating chamber 46 of the connector housing 40.

  First, as shown in FIG. 3, a plurality of terminal-attached electric wires 12 that are accommodated in the exterior member 20 are prepared so that the ends are exposed from the plurality of openings 28 formed in the exterior member 20.

  Here, a plurality of terminal-attached electric wires 12 to which the terminals 16 are crimped in advance are prepared, and are accommodated in the accommodating space 29 of the exterior member 20 so that the end portion is exposed from the predetermined opening 28. In this case, here, the terminal 16 portion and a part of the insulated wire 14 connected to the terminal 16 portion are disposed so as to be exposed to the outside from the opening 28. At this time, it is preferable that the direction of insertion around the axis of the plurality of terminals 16 is matched with the direction of insertion into the terminal accommodating chamber 46 (for example, the caulking portion of the core wire barrel portion is directed upward). Moreover, it is preferable to adjust the axial position of the plurality of terminals 16 to a position corresponding to the terminal accommodating chamber 46. Here, since all the same terminals 16 are inserted into the terminal housing chambers 46 having the same shape, the positions of the tips of all the terminals 16 are aligned. Of course, when the type of the terminal 16 and the type of the terminal accommodating chamber 46 are different, the position of the tip of the terminal 16 may not be aligned.

  However, it is not essential to accommodate a plurality of terminal-attached electric wires 12 to which the terminals 16 are previously crimped, and after accommodating the plurality of insulated wires 14 to which the terminals 16 are not crimped, the terminals 16 are crimped to the insulated wires 14. May be.

  Moreover, it is not essential that a part of the insulated wire 14 connected to the terminal 16 portion is exposed to the outside from the opening 28. For example, as in a first modification described later, the rear end portion of the terminal 16 may be sandwiched between the opening portions 28, and the insulated wire 14 connected to the terminal 16 portion may be completely accommodated in the accommodation space 29.

  Next, the terminals 16 of the plurality of electric wires 12 with terminals housed in the exterior member 20 are inserted into the corresponding terminal housing chambers 46 of the connector housing 40 at a time. Here, the insertion of the terminal 16 is divided into guide insertion and main insertion in two stages.

<Guide insertion>
Before the main insertion, guide insertion is performed first. As shown in FIG. 4, in the guide insertion, at least the distal end portion of the terminal 16 located outside the connector housing 40 is guided to the terminal accommodating chamber 46 and inserted. In other words, in the guide insertion, the terminal 16 is not inserted deep into the terminal accommodating chamber 46.

  Specifically, first, the exterior member 20 in which the terminal-attached electric wire 12 is accommodated so that the central axis of the terminal 16 and the central axis of the terminal accommodating chamber 46 into which the terminal 16 is inserted coincide with each other. Alignment with the connector housing 40 is performed.

  Then, in a state where the central axis of the terminal 16 and the central axis of the terminal accommodating chamber 46 into which the terminal 16 is inserted coincide with each other, the exterior member 20 in which the terminal-attached electric wire 12 is accommodated and the connector housing 40 are relative to each other. Then, the terminal 16 is inserted into the terminal accommodating chamber 46. Here, the exterior member 20 is moved closer to the connector housing 40 while the connector housing 40 is stationary.

  At this time, when inserted to some extent, the tip of the terminal 16 comes into contact with the inner peripheral edge of the portion where the terminal accommodating chamber 46 becomes narrow. Thereby, the load concerning insertion becomes large. In such a state where the load is increased, the approaching movement between the exterior member 20 and the connector housing 40 is stopped, and the exterior member 20 and the connector housing 40 are stopped. This is the guide insertion.

<Insert this>
After the guide is inserted, the main insertion is performed. As shown in FIG. 5, in this insertion, the terminal 16 having at least the distal end portion inserted into the corresponding terminal accommodating chamber 46 is inserted deeply into a predetermined position by guide insertion.

  Specifically, here, the terminals 16 are inserted one by one into the terminal housing chamber 46 one by one with the exterior member 20 and the connector housing 40 being stationary. Thereafter, the insertion is completed by inserting a predetermined number of terminals 16 to the back of the terminal accommodating chamber 46.

  At this time, when the opening portions 28 are formed at both end portions of the exterior member 20 and the terminals 16 of the terminal-attached electric wires 12 extend from both opening portions 28, the other end portion is directly removed without removing the exterior member 20. The terminal 16 can be inserted.

  Note that it is not essential to insert the terminals 16 one by one into the terminal housing chamber 46 one by one in a state where the exterior member 20 and the connector housing 40 are stationary. Also in this insertion, a plurality of terminals 16 may be inserted together. In this case, for example, as in a first modification described later, the main insertion may be performed by moving the exterior member 20 and the connector housing 40 continuously without moving the approaching movement without stopping the approaching movement between the exterior member 20 and the connector housing 40. .

  And since the exterior member 20 and the electric wire 12 with a terminal are being fixed here by the adhesive agent 50, the exterior member 20 is mounted | worn as it is after completion | finish of this insertion. Insertion ends. And the electric wire 12 with a terminal is arrange | positioned in a vehicle, with the exterior member 20 mounted | worn. In this case, the exterior member 20 serves as a protective member for the terminal-attached electric wire 12. At this time, the portion in which the terminal-attached electric wire 12 is not accommodated is removed by cutting or the like at any stage before the guide insertion, after the guide insertion and before the main insertion or after the main insertion. Is preferred. Thereby, the exterior member 20 can be reduced in weight.

  In addition, when the exterior member 20 and the electric wire 12 with a terminal are not being fixed, or when being fixed so that attachment or detachment is possible, the exterior member 20 is removed after the end of the main insertion, so that the terminal housing chamber 46 can be removed. The insertion of the terminal 16 may be terminated. However, the exterior member 20 may be removed after the guide insertion is completed and before the main insertion is started.

  Here, the embodiment has been described in which the single sheathing member 20 accommodates the terminal-attached electric wires 12 corresponding to one connector housing 40, but the single sheathing member 20 corresponds to a plurality of connector housings 40. 12 may be accommodated. In this case, the terminal 16 may be inserted into the plurality of connector housings 40 by one insertion operation, or the terminal 16 may be inserted into each connector housing by another insertion operation once.

<Effect>
According to the electric wire module 10 according to the present embodiment, one of the pitch of the plurality of openings 28 partitioned by the interposition member 24 and the pitch of the plurality of terminal accommodating chambers 46 is formed to be an integral multiple of the other. Therefore, the guides can be inserted into the corresponding terminal accommodating chambers 46 by collecting the terminals 16 of the plurality of electric wires 12 with terminals accommodated in the exterior member 20 at a time.

  Further, since the terminal-attached electric wire 12 is fixed at a certain position in the accommodating space 29 along the extending direction, the terminal 16 extends when the terminal 16 is inserted into the terminal accommodating chamber 46. It is possible to suppress the displacement in the present direction.

  Moreover, since the exterior member 20 holds the electric wire 12 with the terminal so that the terminal 16 is in a constant posture around the axis of the electric wire 12 with the terminal, the terminal 16 is prevented from rotating around the axis of the electric wire 12 with the terminal. Can do. For this reason, the batch insertion of the terminals 16 can be more reliably performed.

{Modifications}
Next, modified examples of the exterior member 20 of the electric wire module 10 according to the embodiment will be described. In the following description of each modification, the same components as those described in the embodiment are denoted by the same reference numerals and description thereof is omitted.

<First Modification>
First, a first modification of the exterior member 20A will be described. FIG. 6 is a schematic plan view showing a first modification of the exterior member 20A. FIG. 7 is a schematic front view showing a first modification of the exterior member 20A.

  In the first modified example of the exterior member 20A, the shape of the opening 28A is different from that of the exterior member 20 of the wire module 10 according to the embodiment.

  Specifically, in the opening portion 28A, the opening portion 28A is formed so that the base portion (portion barrel portion portion) of the terminal 16 fits into the exterior member 20A. Also, here, the exterior member 20A is formed to be elastically deformed when the base portion of the terminal 16 is fitted into the exterior member 20A.

  According to such an exterior member 20 </ b> A, the terminal 16 can be prevented from being displaced in the width direction of the terminal-attached electric wire 12 when the terminal 16 is inserted into the terminal accommodating chamber 46. In addition, the exterior member 20A is elastically deformed in a state where the base portion of the terminal 16 is fitted in the exterior member 20A, whereby the exterior member tightens the terminal 16. Thereby, the shift | offset | difference to the axial direction of the electric wire 12 with a terminal and rotation around an axis | shaft can be suppressed. For this reason, it is possible to more reliably carry out the batch insertion of the plurality of terminals 16.

  At this time, in the connector housing 40A, for example, as shown in FIG. 7, a groove is formed in the frame body 42 and the terminal housing chamber forming body 44 constituting the inner peripheral edge of the terminal insertion side end of the terminal housing chamber 46. If the exterior member 20 is formed so as to be fitted in the groove, the terminals 16 are inserted together by moving the exterior member 20A and the connector housing 40 close to each other even in the main insertion after the guide is inserted. be able to.

<Second Modification>
Next, a second modification of the exterior member 20B will be described. FIG. 8 is a schematic cross-sectional view showing a second modification of the exterior member 20B. FIG. 8 is a cross-sectional view taken at the same position as in FIG.

  The second modification of the exterior member 20B is different from the exterior member 20 of the electric wire module 10 according to the embodiment in that the terminal stopper 30 is provided. The terminal stopper 30 is provided in the opening 28. Even when the terminal 16 is pushed to the inner peripheral edge of the terminal accommodating chamber 46 when the terminal 16 is inserted into the terminal accommodating chamber 46, the terminal 16 is inserted into the accommodating space 29 from the opening 28. This is the part that prevents entry.

  Specifically, the plate-like member 22 and the interposition member 24 of the exterior member 20 </ b> B are formed in the same manner as the plate-like member 22 and the interposition member 24. And the terminal stop part 30 is provided in the internal peripheral surface from the opening part 28 to the inner side among the accommodation spaces 29 here.

  More specifically, the terminal stopper 30 is made of an elastic material and is compressible in the height direction. Further, the terminal stopper 30 is formed so that its height is gradually reduced from the opening 28 toward the inside. Thereby, when exposing an electric wire edge part outside from the opening part 28, it can suppress that the terminal stop part 30 becomes obstructive.

  However, it is not essential that the terminal stopper 30 is formed of an elastic material and is compressible in the height direction, and may be formed of an inelastic material. Further, it is not essential that the terminal stopper 30 is formed so that its height is gradually decreased from the opening 28 toward the inside. For example, the terminal stopper 30 is directed from the outward end of the opening 28 to the inside. You may form so that the height may become high sequentially.

  According to such an exterior member 20 </ b> B, even when the terminal 16 is pushed into the inner peripheral edge of the terminal accommodating chamber 46 when the terminal 16 is inserted into the terminal accommodating chamber 46, the terminal 16 extends from the opening 28 to the accommodating space 29. You can prevent it from getting inside.

  At this time, if the connector housing 40 as described in detail in the first modification is employed, the terminal 16 is more securely connected to the terminal accommodating chamber 46 even when a load is applied to the terminal 16 when the terminal 16 is inserted. It can be inserted all the way.

<Third Modification>
Next, a third modification of the exterior member 20C will be described. FIG. 9 is a schematic front view showing a third modification of the exterior member 20C.

  The third modification of the exterior member 20C is different from the exterior member 20 of the electric wire module 10 according to the embodiment in that a plurality of openings 28 are provided.

  Specifically, here, the three plate-like members 22 are provided in parallel and spaced apart, and the interposition member 24 is provided between each of the plate-like members 22, whereby the opening portion 28 of the exterior member 20. Has two stages.

  According to such an exterior member 20, when the terminal housing chamber 46 of the connector housing 40 has two stages, the terminals 16 can be inserted all at once. If the terminal housing chamber 46 of the connector housing 40 has three or more stages, the number of the plate-like members 22 and the number of the interposition members 24 are provided by the number corresponding to the number of stages of the terminal housing chamber 46 of the connector housing 40. Thus, the number of stages of the opening 28 can be matched to the number of stages of the terminal accommodating chamber 46 of the connector housing 40. Thereby, even when the terminal housing chambers 46 of the connector housing 40 have three or more stages, the terminals 16 can be inserted all at once.

<Fourth Modification>
Next, a fourth modification of the exterior member 20D will be described. FIG. 10 is a partially cutaway perspective view showing a fourth modification of the exterior member 20D.

  The fourth modification of the exterior member 20D is different from that of the exterior member 20 of the electric wire module 10 according to the embodiment in the shape of the interposed member 24D.

  Specifically, the interposition member 24 </ b> D of the exterior member 20 according to the fourth modification is formed in an elongated plate shape and is provided so as to be orthogonal to the pair of plate members 22. A plurality of interposition members 24D are provided in a parallel state with a space therebetween. Thereby, exterior member 20D is formed in the shape which has a ladder-like section. In addition, a rectangular opening 28D and an accommodation space 29D connected to the rectangular opening 28D are formed in a space between the pair of plate-like members 22 and each interposed member 24D.

  Here, in the exterior member 20D, the plate-like member 22 and the interposition member 24D are integrally formed of a resin material. Such an exterior member 20D can be continuously manufactured by, for example, an extrusion molding apparatus that extrudes resin from an extrusion hole corresponding to the ladder-shaped cross section. Thereby, exterior member 20D can be manufactured easily at low cost.

  The shape of the opening 28D formed by the interposed member 24D interposed between the plurality of plate-like members 22 is not limited to a rectangle. For example, by setting the interposition member 24D slightly inclined from the state orthogonal to the plate-like member 22, in other words, by setting the angle between the interposition member 24D and the plate-like member 22 to an angle other than 90 degrees, The shape of the opening 28D can be a triangle, a parallelogram, or a trapezoid. Further, by bending the interposition member 24D in the middle from the one plate-like member 22 to the other plate-like member 22, the shape of the opening 28D can be made a polygon that is a pentagon or more.

  According to such an exterior member 20D, the exterior member 20D can be easily manufactured at low cost because it is integrally formed of a resin material.

<Fifth Modification>
Next, a fifth modification of the exterior member 20E will be described. FIG. 11 is a partially cutaway perspective view showing a fifth modification of the exterior member 20E.

  As in the fourth modification, the fifth modification of the exterior member 20E is different from that of the exterior member 20 of the wire module 10 according to the embodiment in the shape of the interposition member 24E.

  Specifically, the interposition member 24E has a configuration in which a plurality of protrusions 25a are formed so as to be scattered in a plan view. Here, in a state in which the interposed member 24E is viewed in plan, the plurality of protrusions 25a are formed so as to be arranged in lattice points at regular intervals vertically and horizontally. The protrusion 25a is formed so as to protrude toward the one main surface side from the substrate portion 25b extending in a planar shape in the interposition member 24E, and has a shape in which the upper end portion of the cylinder is closed. Here, the protrusion 25a is formed in a shape that gradually narrows upward, that is, a frustum shape. The protrusion 25a may be formed in a truncated cone shape, may be formed in a truncated pyramid shape, or may be formed in a shape obtained by rounding the corners of the truncated pyramid.

  Then, the interposition member 24E is sandwiched between the plurality of plate-like members 22, the lower surface of the substrate portion 25b is joined to the lower plate-like member 22, and the top of the protrusion 25a is joined to the upper plate-like member 22. ing.

  Also with such an exterior member 20E, a plurality of openings 28E are formed in parallel on one end side of the plate-like member 22 in the same manner as the exterior member 20 described above.

  Moreover, according to such an exterior member 20E, since the plurality of protrusions 25a are formed in a lattice point shape, the terminal-attached electric wire 12 can be accommodated in the accommodation space 29E in a bent state. Moreover, the exterior member 20E can be reduced in weight.

  Here, the protrusion 25 a is provided slightly inside from the end of the plate-like member 22. Thereby, the terminal 16 can be inserted | pinched between the one plate-shaped member 22 and the board | substrate part 25b of the interposition member 24E in the edge part of the plate-shaped member 22. FIG.

  In addition, each structure demonstrated by 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.
