<2. Structure of pressure contact terminal holding part>
Next, the structure of the press contact terminal holding part 20 will be described. The structure of the press contact terminal holding portion 20 is applied to various electric circuit components in which the electric wire 40 is laid and the press contact terminal 10 capable of being press-contacted to the electric wire 40 is disposed.

  2 is a cross-sectional view of the press contact terminal holding portion 20 according to the first embodiment when cut in the direction of one principal surface of the press contact terminal 10, and FIG. 3 is a cross section of the press contact terminal holding portion 20 taken along the line III-III in FIG. FIG. 4 is a view showing a state in which the contact portion between the press contact leg portion 14 and the electric wire 40 is laser-welded in the press contact terminal holding portion 20 according to the first embodiment. In the following description, the vertical and horizontal directions may be used in accordance with the direction of the press contact terminal holding portion 20 shown in FIGS. 2 to 4. However, this direction is used for convenience of description and the posture of the press contact terminal holding portion 20 is limited. Not what you want.

  The press contact terminal holding portion 20 is integrally molded with a plate-like member 21 provided in an electric circuit component or the like. And the electric wire is wired by the predetermined wiring pattern to the plate-shaped member 21, and the press-contact terminal holding | maintenance part 20 is formed in the position along the wiring pattern. The press contact terminal holding portion 20 includes a terminal support portion 22, a press contact auxiliary portion 24, a plurality of insulating protrusions 26, and an annular protrusion 28. The press contact terminal holding portion 20 includes a plurality of wire holding slits. 36 and a recess 38 are formed.

  The terminal support portion 22 has a plurality of press-fit holes 32 into which the press-fit portion 12 of the press contact terminal 10 can be press-fitted. The press-fit hole 32 is formed in a substantially rectangular parallelepiped space that opens in a thin rectangular shape outside the press contact terminal holding portion 20. More specifically, the press-fit hole 32 is set to a size smaller than (in this case, slightly smaller) the width of the press contact terminal 10 in the width direction (left and right direction in FIG. 2), and the depth direction ( In the vertical direction in FIG. 2, the dimension is set to be the same as or longer than the dimension of the press-fit portion 12 in the insertion direction of the press contact terminal 10 (substantially the same here). Further, the press-fit hole 32 is set to a dimension that is approximately the same as the thickness dimension of the press-fit portion 12 in the thickness direction (left-right direction in FIG. 3). Then, in a state where the press-fit portion 12 of the press contact terminal 10 is inserted into the press-fit hole 32, the inner peripheral wall forming the press-fit hole 32 in the terminal support portion 22 contacts the outer peripheral portion of the press-fit portion 12. The support portion 22 supports the press contact terminal 10. At this time, the press contact terminal 10 is supported in such a posture that the press contact leg portion 14 faces the front side (lower side) in the insertion direction and the connection portion 16 faces the rear side (upper side) in the insertion direction.

  As a result, the press-connecting terminal holding part 20 has a posture in which the center axis direction of the press-connecting terminal 10 and the insertion direction substantially match with the press-fit part 12 of the press-connecting terminal 10 being press-fit into the press-fit hole 32, and The press contact terminal 10 can be supported so that there is no rattling.

  The pressure contact auxiliary portion 24 is formed continuously below the pressure contact terminal 10 with respect to the terminal support portion 22. Here, the pressure contact assisting part 24 is integrally formed with the plate-like member 21. In addition, a plurality of pressure contact holes 34 into which the pressure contact leg portions 14 can be inserted are formed in the pressure contact assisting portion 24. Each pressure contact hole 34 is formed linearly and continuously below the pressure insertion hole 32 along the insertion direction of the pressure contact terminal 10. That is, a plurality of press-fit holes 32 and press-contact holes 34 are formed. Further, the pressure contact hole 34 is formed in a substantially rectangular parallelepiped space that opens in a substantially rectangular shape in a recess 38 to be described later. Here, the pressure contact hole 34 is set to have substantially the same size as the size between the outer edge portions on both sides of the pressure contact leg portion 14 in the width dimension (left and right direction in FIG. 2). Then, in a state where the pressure contact leg portion 14 is inserted into the pressure contact hole 34, the pressure contact recess portion 15 of the pressure contact leg portion 14 is cut into the covering portion of the electric wire 40 inserted and arranged in the electric wire holding slit 36 described later, and pressed. Both side edges of the recess 15 come into contact with the core portion of the electric wire 40 and are electrically connected. At this time, the inner side walls on both sides in the width direction forming the press-contact holes 34 in the press-contact auxiliary portion 24 come into contact with both outer edge portions of the press-contact leg portions 14, and the opening of the press-contact leg portions 14 is suppressed. Thereby, the electrical connection state of the press-contacting leg part 14 and the core part of the electric wire 40 is more reliably maintained.

  A plurality of the electric wire holding slits 36 are formed so as to extend from the upper side to the lower side in the terminal insertion direction in the upper portion of the press contact terminal holding portion 20 so that the electric wires 40 can be inserted and arranged. Here, the electric wire holding slit 36 includes a portion forming inner walls on both sides in the thickness direction of the press-fit hole 32 in the terminal support portion 22 and an inner side on both sides in the thickness direction of the press-contact hole 34 in the press-contact auxiliary portion 24. It forms over the part which forms the wall. That is, the electric wire holding slits 36 are formed on both sides of the press-fitting hole 32 and the press-contact hole 34 in the thickness direction. And the electric wire holding slit 36 is formed in the dimension which can be inserted and arranged so that the electric wire 40 may traverse the inside of the pressure contact hole 34 in the thickness direction. That is, the inner part of the electric wire holding slit 36 is formed so as to reach the press-contact auxiliary part 24. Further, the width dimension of the electric wire holding slit 36 is formed to be smaller (here, slightly smaller) than the outer diameter of the electric wire 40 (the outer diameter of the covering portion). Thus, since the electric wire 40 is inserted and arranged in the electric wire holding slit 36, the electric wire 40 can be held so as to cross the pressure contact hole 34.

  Further, the pressure contact hole 34 is set to be larger than the thickness dimension of the press contact leg 14 in the thickness dimension (left and right direction in FIG. 3). Here, the pressure contact hole 34 has such a size that the inner walls on both sides in the thickness direction forming the pressure contact hole 34 in the pressure assisting portion 24 face the pressure contact leg 14 with a gap. Is formed. As described above, in the press contact terminal holding portion 20, the press contact hole 34 is formed in such a size that a gap is provided between the press contact hole 14 and the press contact leg portion 14 in the thickness direction. When the contact portion is welded with laser light, melting of the press contact terminal holding portion 20 can be suppressed.

  The recess 38 is formed in the lower part of the press contact terminal holding part 20 so as to open outward. And the recessed part 38 is formed so that the contact part of the press-contact leg part 14 and the electric wire 40 may face outward from the to-be-contacted hole 34 opened in the bottom part. The aspect in which the contact portion between the pressure contact leg portion 14 and the electric wire 40 faces outward is only required to irradiate the contact portion without irradiating the pressure contact terminal holding portion 20 with laser light. Preferably, the recess 38 is formed to have a depth dimension such that at least a part of the contact portion is disposed at substantially the same position as the outward opening edge in the depth direction of the recess 38. Further, here, the recess 38 is formed to have a depth dimension that allows the tip end portion of the press contact leg portion 14 to protrude from the press contact hole 34. The recess 38 is formed to have a size larger than the size between the opening edge portions of the pressure contact holes 34 at both ends of the plurality of pressure contact holes 34 in the width direction of the pressure contact hole 34 (left and right direction in FIG. 2). In addition, in the thickness direction of the pressure contact hole 34 (left and right direction in FIG. 3), it is formed to have the same size as the dimension of the pressure contact hole 34.

  Thus, since the contact portion between the press contact leg portion 14 and the electric wire 40 can be exposed outward by forming the recess 38, when the contact portion between the press contact leg portion 14 and the electric wire 40 is laser-welded, As shown in FIG. 4, it is possible to prevent the laser light emitted from the laser welding head 50 from being applied to the press contact terminal holding unit 20. And the contact part of the press-contact leg part 14 and the electric wire 40 can be laser-welded, preventing the fusion | melting of the press-contact terminal holding part 20 like FIG. In addition, since the distal end portion of the press contact leg 14 and the press contact connection portion (weld connection portion) between the press contact leg portion 14 and the electric wire 40 are located near the bottom (back side) of the recess 38, the press contact leg portion 14. It is possible to suppress short-circuiting or the like of the distal end portion and the pressure contact connecting portion (welded connection portion) between the pressure contact leg portion 14 and the electric wire 40 with other members outside the concave portion 38.

  The annular projecting portion 28 is formed on the outer periphery of the recessed portion 38 and extends to the lower side of the press contact terminal holding portion 20. As described above, the distal end portion of the press contact leg 14 and the press contact connection portion (weld connection portion) between the press contact leg portion 14 and the electric wire 40 are positioned in the back of the space surrounded by the annular protrusion 28 (near the bottom of the recess 38). Therefore, it is possible to further suppress a short circuit or the like of the distal end portion of the press contact leg portion 14 and the press contact connection portion between the press contact leg portion 14 and the electric wire 40 with other members outside the recess 38.

  The insulating convex portion 26 projects outwardly into the concave portion 38 so as to partition the tip portion projecting from the pressure contact hole 34 of the press contact leg 14 adjacent between the outer openings of the plurality of pressure contact holes 34. A plurality are formed. More specifically, the insulating protrusions 26 each divide the tip end portion of the adjacent press contact leg portion 14 into the portion between the adjacent pressed contact holes 34 in the press contact auxiliary portion 24 (left and right direction in FIG. 3). It is formed along. Further, the insulating convex portion 26 is inserted into the pressure contact hole 34 and protrudes from the outer opening thereof with respect to the tip end portion of the adjacent pressure contact leg portion 14 (here, it does not contact the outer edge portion of the pressure contact leg portion 14). It is formed so as to provide a gap of a certain degree. That is, the insulating convex portion 26 is formed thinner in the width direction of the pressure contact hole 34 than the portion that partitions the pressure contact hole 34 of the pressure assisting portion 24, and the side surface thereof is from each opening edge of the adjacent pressure contact hole 34. It is formed at a separated position. Further, the projecting dimension of the insulating convex portion 26 is such that the press contact leg portion that protrudes outward from the press contact hole 34 in a state where the press contact leg portion 14 is inserted into the press contact contact hole 34 in the insertion direction of the press contact terminal 10. It is formed to be the same as or larger than the tip portion of 14 (slightly larger here).

  As described above, since the insulating convex portions 26 projecting so as to partition the adjacent press-contact holes 34 in a state where a gap is provided with respect to the press-contact legs 14, the press-contacts projecting from the plurality of press-contact holes 34 are formed. A longer insulation creepage distance can be ensured between the legs 14 and the insulation can be improved.

  According to the structure of the press contact terminal holding portion 20 as described above, the press contact terminal 10 is held because the press fit portion 12 of the press contact terminal 10 is press fit into the press-fit hole 32 formed in the terminal support portion 22. Further, the press-fit portion 12 of the press-contact terminal 10 is press-fitted into the press-fit hole 32, and the press-contact leg portion 14 is inserted into the press-contact hole 34 formed in the press-contact auxiliary portion 24 so as to be inserted into the electric wire holding slit 36. Since it is press-connected to the electric wire 40, the holding of the electric wire 40 and the opening of the press-contact leg portion 14 can be suppressed to maintain the press-contact state. Further, since a concave portion 38 is formed so that the contact portion between the pressure contact leg portion 14 and the electric wire 40 faces the outside from the pressure contact hole 34, the laser welding head 50 is moved in the direction of the arrow during laser welding as shown in FIG. The irradiated laser beam can be prevented from being applied to the press contact terminal holding portion 20, and the press contact leg portion 14 and the electric wire 40 can be welded without melting the press contact terminal holding portion 20. In addition, since the distal end portion of the pressure contact leg 14 and the pressure contact connection portion (welding connection portion) between the pressure contact leg portion 14 and the electric wire 40 are located near the bottom of the recess 38, the front end portion of the pressure contact leg portion 14 and It can suppress that the press-contact connection part (welding connection part) of the press-contact leg part 14 and the electric wire 40 short-circuits with the other member outside the recessed part 38, etc. Then, the press contact terminal holding portion 20 formed of resin melts, and the weld strength is insufficient due to the occurrence of foreign matter or voids in the laser welded portion between the press contact leg 14 and the electric wire 40, and the press contact due to the occurrence of wrinkles, etc. The contamination of the terminal holding part 20 can be suppressed. Furthermore, problems such as a short circuit with other circuits due to the press contact terminal holding portion 20 being melted in the peripheral portion of the press-fit hole 32 and the press contact leg portion 14 being largely exposed to the outside can be prevented.

  Further, since the annular protrusion 28 is formed on the outer periphery of the concave portion 38, the distal end portion of the pressure contact leg 14 and the pressure contact connection portion (welding connection portion) between the pressure contact leg 14 and the electric wire 40 are the annular protrusion 28. Therefore, it is possible to further suppress a short circuit between the press contact leg portion 14 of the press contact terminal 10 protruding into the recess 38 and other members.

  In addition, an insulating convex portion 26 is formed between the outer openings of the plurality of pressure contact holes 34 and protrudes so as to partition the adjacent pressure contact holes 34 with a gap provided between the pressure contact legs 14. Further, it is possible to secure a longer insulation creepage distance between the pressure contact legs 14 protruding from the plurality of pressure contact holes 34.

  In addition, the pressure contact hole 34 is larger than the thickness dimension of the pressure contact leg 14 in the thickness direction of the pressure contact leg 14 and is formed so as to provide a gap between the pressure contact leg 14. It is possible to further suppress melting of the pressure welding auxiliary portion 24 when laser welding the contact portion between the pressure welding leg portion 14 and the electric wire 40.

  In addition, the pressure contact terminal 10 is inserted from the surface side where the electric wire is laid in the plate-like member 21 such as an electric circuit component, and the connection portion 16 protrudes from the surface side where the electric wire is laid. Can be held.
