{First embodiment}
Hereinafter, the wiring module according to the first embodiment will be described.

  FIG. 1 is a schematic perspective view showing the wiring module 1 attached to the vehicle body panel 70. FIG. 2 is a schematic perspective view showing a state where the insulating portions 22 and 24 and the fixing portion 40 are attached to the press-fit pin 10.

FIG. 4 is a cross-sectional view of each part showing a state where the press-fit pin 10 is inserted into the through hole 31 of the laminate 30. FIG. 5 is a cross-sectional view of each part showing a state where the press-fit pin 10 is inserted into the through hole 31 of the laminate 30.

  The wiring module 1 includes a press-fit pin 10, insulating portions 22 and 24, a laminate 30, a fixing portion 40, an electric wire 50 as another wiring member, one end (upper end in the drawing) of the press-fit pin 10, and A crimping portion 60 that crimps one end of the electric wire 50 (the lower end in the drawing).

  The stacked body 30 includes conductive plates 32 to 34 that are stacked while being insulated from each other.

  The conductive plates 32 to 34 are formed in a long shape, and a cross section in a plane orthogonal to the longitudinal direction is formed in a flat shape. The conductive plates 32 to 34 are formed of elongated strip-shaped metal plates. That is, the conductive plates 32 to 34 are flat electric wires formed of a material such as copper, copper alloy, aluminum, or aluminum alloy. The conductive plates 32 to 34 may be subjected to metal plating such as tin or nickel.

  Here, the surfaces of the three conductive plates 32 to 34 are individually coated with insulating films 32a to 34a. A portion of the insulating films 32a to 34a interposed between the conductive plates 32 to 34 serves to electrically insulate the conductive plates 32 to 34 from each other.

  But the laminated body 30 may be comprised by laminating | stacking two electrically conductive plates, and may be comprised by laminating | stacking 4 or more electrically conductive plates. Moreover, the aspect which mutually insulates each electrically conductive plate may be formed by extrusion-coating resin around each electrically conductive plate.

  Such a laminate 30 can be used, for example, as a wiring member of a wattmeter that electrically connects a battery and a DC-DC converter, a starter / generator, an inverter, or the like in a vehicle.

  The laminated body 30 is provided with a plurality of through holes 31 that penetrate the conductive plates 32 to 34 in the thickness direction (for example, a direction orthogonal to the respective conductive plates 32 to 34). In the example shown in FIG. 1, two rows of through-holes 31 arranged at equal intervals along the longitudinal direction are provided on each side of the lateral direction with respect to the laminate 30.

  As shown in FIGS. 4 and 5, the conductive plates 32 to 34 and the insulating films 32 a to 34 a are exposed on the inner wall surface of the through hole 31. For this reason, by bringing the press-fit pin 10 into contact with the conductive plates 32 to 34 exposed in the through hole 31, the contacted conductive plate and the press-fit pin 10 can be electrically connected. Below, the aspect which makes the press fit pin 10 and the electrically conductive board 33 contact in the through-hole 31 is demonstrated.

  The press-fit pin 10 includes a conductive shaft portion 11 and three press-fit portions 12 to 14 that are provided apart along the shaft portion 11. In a state where the press-fit pins 10 are inserted into the through holes 31 of the multilayer body 30, the press-fit portions 12 to 14 are arranged at positions corresponding to the conductive plates 32 to 34 constituting the multilayer body 30.

  The shaft portion 11 is a long conductive member. The diameter of the shaft portion 11 is smaller than the diameter of each through hole 31 in the laminate 30.

  The press-fit portion 12 is a conductive member having a pair of arc-shaped portions 12a provided with a gap in a side view. The press-fit portion 12 can be elastically deformed in a direction in which the pair of arcuate portions 12a approach (that is, a diameter-reducing direction) or a direction that separates (ie, a diameter-enlarging direction) by an external force from the side.

  In a normal state where there is no external force, the width of the press-fit portion 12 is larger than the inner diameter of the through hole 31 in the laminate 30. On the other hand, in a state in which a pressing force from the side acts on the press-fit portion 12, the press-fit portion 12 is elastically deformed in the reduced diameter direction. For example, when the press-fit portion 12 is inserted into the insulating portion 22, the press-fit portion 12 is elastically deformed in the reduced diameter direction until the width of the press-fit portion 12 is substantially the same as the inner diameter of the insulating portion 22. To do. Further, when the press fit portion 12 is inserted into the through hole 31, the press fit portion 12 is elastically deformed in the reduced diameter direction until the width of the press fit portion 12 is substantially the same as the inner diameter of the through hole 31. To do.

  The press fit portions 13 and 14 have the same configuration as the press fit portion 12. In other words, the press-fit portion 13 is a conductive member that has a pair of arc-shaped portions 13a and can be elastically deformed in the direction of diameter reduction or diameter expansion. The press-fit portion 14 has a pair of arc-shaped portions 14a and is a conductive member that can be elastically deformed in the reduced diameter direction or the increased diameter direction. The press-fit pin 10 is manufactured, for example, by punching a part of a rolled conductive plate with a press.

  In the present embodiment, the insulating portion 22 is provided on the outer periphery of the press-fit portion 12 among the three press-fit portions 12 to 14 provided in order from the distal end side (the lower side in the drawing) of the press-fit pin 10 with respect to the shaft portion 11. And an insulating part 24 is provided on the outer periphery of the press-fit part 14.

  The insulating portion 22 has annular convex portions formed in a projecting shape in the radial direction and annular concave portions formed in a groove shape alternately along the axial direction (vertical direction in the drawing) of the press-fit pin 10, A cylindrical member into which the press-fit pin 10 is inserted. The length of the insulating portion 22 in the axial direction is longer than the length of the press-fit portion 12 in the axial direction, and is substantially the same as the combined thickness of the conductive plate 32, the insulating film 32a, and the vehicle body panel 70.

  The insulating portion 24 alternately has an annular convex portion formed in a protruding shape in the radial direction and an annular concave portion formed in a groove shape along the axial direction (vertical direction in the drawing) of the press-fit pin 10, A cylindrical member into which the press-fit pin 10 is inserted. The length of the insulating portion 24 in the axial direction is longer than the length of the press-fit portion 14 in the axial direction, and is substantially the same as the combined thickness of the conductive plate 34 and the insulating film 34a.

  The inner diameters of the insulating portions 22 and 24 are smaller than the outer diameters of the press fit portions 12 and 14 in the normal state. For this reason, in a state where the press-fit pins 10 are inserted into the insulating portions 22 and 24, the press-fit portions 12 and 14 are elastically deformed in a direction in which they are pressed from the inner wall surfaces of the insulating portions 22 and 24 and contract. The inner wall surfaces of the insulating portions 22 and 24 are pressed by the restoring force. As a result, the press fit portions 12 and 14 are fixed to the insulating portions 22 and 24.

  The fixing portion 40 is an insulating member that is fixed to a counterpart member (for example, the vehicle body panel 70) that is to be fixed. Moreover, the base end part (illustrated upper end part) of the fixing | fixed part 40 is comprised integrally with the edge part (illustrated lower end part) of the insulation part 22 (refer FIG. 2, FIG. 3). Although schematically shown in the drawing, the fixing portion 40 is a clamp in which a pair of locking pieces expands from the distal end portion toward the proximal end portion. When the fixing portion 40 is attached to the vehicle body panel 70, the fixing portion 40 is passed through the hole 71 of the vehicle body panel 70 while elastically deforming the proximal end portion of the clamp in the diameter reducing direction. The fixed portion 40 is locked to the vehicle body panel 70 by the base end portion of the fixed portion 40 returning to the original shape by the restoring force after the penetration.

  In the press-fit pin 10 to which the insulating portions 22 and 24 are attached, the diameters of the insulating portion 22, the press-fit portion 13, and the insulating portion 24 are set larger than the inner diameter of the through hole 31 provided in the laminate 30. The

  For this reason, in a state where the press-fit pin 10 to which the insulating portions 22 and 24 are mounted is inserted into the through-hole 31 of the laminated body 30 (hereinafter referred to as an inserted state), the insulating portion 22 penetrates due to elastic deformation restoring force. The inner wall surface of the hole 31 (specifically, the portion where the conductive plate 32 and the insulating film 32a are exposed) is pressed. In this inserted state, the press-fit portion 13 presses the inner wall surface of the through hole 31 (specifically, the portion where the conductive plate 33 is exposed) by the restoring force of elastic deformation. In this inserted state, the insulating portion 24 presses the inner wall surface of the through hole 31 (the portion where the conductive plate 34 and the insulating film 34a are exposed) by the restoring force of elastic deformation. As described above, the press-fit portion 13 and the insulating portions 22 and 24 have a function of fixing the press-fit pin 10 to the laminated body 30 by elastic deformation in the through hole 31.

  In the inserted state, each part (the press fit part 13 and the insulating parts 22, 24) having a diameter larger than that of the shaft part 11 is in contact with the inner wall of the through hole 31, and the shaft part 11 is separated from the inner wall of the through hole 31. ing. In the inserted state, the press-fit portion 12 and the conductive plate 32 are not electrically connected by the interposition of the insulating portion 22, and the press-fit portion 13 and the conductive plate 33 are electrically connected by contact, and the press-fit portion 14 and the conductive plate 34 are not electrically connected by the interposition of the insulating portion 24. As a result, the conductive plate 33 and the press-fit pin 10 (and thus the press-fit pin 10 and the electric wire 50 to be crimped) are electrically connected.

  In the present embodiment, at least one of the plurality of press-fit portions 12 to 14 (specifically, the press-fit portion 13) presses the inner wall of the through-hole 31 with the restoring force of elastic deformation, thereby The wiring module 1 that is electrically connected to at least one of the conductive plates 32 to 34 (specifically, the conductive plate 33) has been described. As in the wiring module 1 of the present embodiment, by adjusting the number and position of the press-fit portions that are electrically connected to the conductive plate, the electrical connection mode between the plurality of stacked conductive plates and the press-fit pins Can be adjusted.

  Moreover, in this embodiment, the press fit pin 10 has the several press fit parts 12-14 in the position corresponding to each of the several conductive plates 32-34 in an insertion state. For this reason, it is possible to electrically connect each conductive plate and each press-fit pin.

  Moreover, in this embodiment, the three press fit parts 12-14 are provided, and one press fit part 13 is electrically connected with one conductive plate 33 among these press fit parts 12-14, and the remaining press Insulating portions 22 and 24 are provided on the outer periphery of the fitting portions 12 and 14. For this reason, it can suppress that the press fit parts 12 and 14 and the electrically conductive plates 32 and 34 are not electrically connected unintentionally.

  Moreover, in this embodiment, in order to insert the press fit pin 10 in the cylindrical insulation parts 22 and 24, the press fit parts 12 and 14 and the electrically conductive plates 32 and 34 are electrically connected unintentionally. Can be effectively suppressed. Moreover, the insulation parts 22 and 24 have an annular convex part and an annular recessed part alternately along an axial direction. For this reason, when the press-fit pin 10 is inserted into the cylindrical insulating portions 22 and 24, the annular recess is elastically deformed in the diameter increasing direction, and after the insertion, the annular recess is reduced in the direction of diameter reduction due to the restoring force of the elastic deformation. As a result, the insulating portions 22 and 24 are fixed to the press-fit pin 10 (more specifically, the press-fit portions 12 and 14).

  Further, in the present embodiment, the inserted wiring module 1 is fixed to the vehicle body panel 70 by passing the fixing portion 40 provided on the distal end side of the press fit pin 10 through the hole 71 of the vehicle body panel 70. . As described above, the press-fit pin 10 of the present embodiment also realizes mechanical fixing of the wiring module 1 to the vehicle body panel 70 in addition to electrical connection to the conductive plate 33 using the press-fit pin 10. Can do. Note that this electrical connection and mechanical fixing may be performed at different timings. That is, after the press-fit pins 10 are inserted into the laminate 30 and the wiring module 1 is completed, the wiring module 1 may be moved to another place and attached to the vehicle body panel 70.
