  It is desired that a variety of electronic devices be mounted on the automobile described above. For this reason, the electric wire and connector which comprise the wire harness mentioned above tend to increase. For this reason, downsizing of the connector, that is, the pressure contact terminal described above is desired. For this reason, the applicant of the present invention has proposed a press contact terminal in which the dimension in the width direction is particularly reduced by not providing a side wall in the press contact portion.

  The pressure contact portion of this type of pressure contact terminal includes the above-described substrate, a bent portion connected to one edge in the width direction of the substrate, and a bottom plate that is connected to the bent portion and is bent to be overlapped with the substrate. And a press-contact blade standing from the bottom plate portion. Since the metal plate constituting the press contact terminal is thick, the bottom plate portion overlaps the substrate particularly in a state of being shifted in the width direction. The bottom plate portion protrudes outward from the edge in the width direction of the substrate.

  Thus, the bottom plate portion and the substrate are displaced in the width direction. For this reason, when the electric wire is press-fitted into the press-contacting blade, ie, when the electric wire is press-fitted into the press-contacting portion, the bottom plate portion and the substrate are displaced in the width direction due to the force acting on the press-contacting blade from the electric wire. Is inclined with respect to the substrate, and the pressure contact blade is considered to buckle. As described above, it is considered that it is difficult to reliably press the electric wire to the press contact blade, that is, the press contact portion, in the press contact terminal reduced in size without providing the side wall.

  Accordingly, an object of the present invention is to provide a connector that can reliably press-contact an electric wire to a press-contact terminal even if the press-contact terminal is downsized.

In order to solve the above problems and achieve the object, the connector of the present invention according to claim 1 includes a wire connection portion connected to an electric wire and a pressure contact portion provided with an electric contact portion connected to an end portion of the substrate of the wire connection portion. a terminal, a connector and a plate-like housing mounting the pressure contact terminal, the electric wire connecting part includes a bent portion continuous with one edge in the width direction of the base plate, with the bent portion Narikatsu before Symbol a bottom plate having a protrusion protruding outwardly bent portion bent from said one edge of the overlap with Rutotomoni the substrate to the substrate, pressure to the electric wire pressure contact one only erected from the bottom plate portion A first center line that bisects the width of the substrate and a second center line that bisects the width of the electrical contact portion are shifted in the width direction of the press contact terminal, The first center line is wider than the second center line. Is disposed on the other edge side of direction, the plate-like housing, the protrusion of the pressure contact terminal of the the terminal accommodating groove for accommodating the press-connecting terminal, a convex from the bottom surface of the terminal accommodating grooves, and the terminal receiving groove It is characterized in that it has a convex portion where the portions overlap closely .

  According to a second aspect of the present invention, there is provided the connector according to the first aspect, wherein the protruding amount of the convex portion from the bottom surface of the terminal receiving groove is equal to the thickness of the substrate.

  A connector according to a third aspect of the present invention is the connector according to the first or second aspect, wherein the convex portions are provided in pairs with a space therebetween, and the pair of convex portions are disposed between each other. The bent portion is positioned.

  A connector according to a fourth aspect of the present invention is the connector according to any one of the first to third aspects, wherein the press contact terminal is arranged in a direction intersecting the surface of the main body of the plate-shaped housing. And press-fitting into the terminal receiving groove.

Connector of the present invention according to claim 5, in connector as claimed in any one of claims 1 to 4, a third center line bisecting a width of the front Symbol pressure-blades, the The second center line is characterized by being located on the same straight line.

  According to the connector of the present invention described in claim 1, the press contact terminal includes the bent portion connected to the substrate, the bottom plate portion connected to the bent portion and overlapped with the substrate, and the press contact blade standing from the bottom plate portion. . Thus, the press contact terminal does not provide a pair of side walls that are connected to the press contact blade and the substrate. For this reason, the dimension in the width direction of the press contact terminal can be shortened.

  Further, the bottom plate portion is provided with a protruding portion protruding from at least one edge in the width direction of the substrate, and the plate-like housing is provided with a protruding portion that protrudes from the bottom surface and contacts the protruding portion. For this reason, when the press contact terminal is attached to the plate-shaped housing, the above-described protruding portion is supported by the convex portion.

  According to the connector of the present invention described in claim 2, since the protrusion amount of the protrusion and the thickness of the substrate are equal, when the press contact terminal is attached to the plate-like housing, the protrusion reliably Can support.

  According to the connector of this invention described in Claim 4, a terminal metal fitting is press-fit in a terminal accommodating groove along the direction which cross | intersects the surface of the main-body part of an insulator. For this reason, the thickness of the plate-shaped housing in the direction intersecting the surface of the main body can be suppressed by the insulator that press-fits the terminal fitting into the terminal accommodating chamber along the longitudinal direction of the terminal fitting and the terminal accommodating chamber.

Further, since the side wall is not provided, the work of bending the sheet metal to form the press contact terminal is facilitated, and the productivity of the press contact terminal is improved.

  Further, when the press contact terminal is attached to the plate-shaped housing, the protruding portion protruding from one edge of the substrate is supported by the protruding portion. For this reason, it is possible to prevent the bottom plate portion from being inclined with respect to the substrate and to prevent the press contact blade and the like from buckling when being pressed to the press contact terminal. Therefore, the electric wire can be reliably pressed against the press contact terminal.

  Furthermore, the rigidity of the plate-shaped housing is improved by the convex portion protruding from the bottom surface of the terminal receiving groove of the plate-shaped housing. For this reason, if the rigidity is kept the same as that without a convex portion, the plate-shaped housing can be made smaller than that without a convex portion. In other words, the connector can be miniaturized.

  Further, since the rigidity of the plate-shaped housing is improved by the convex portion, it is possible to prevent the plate-shaped housing from being elastically deformed when the pressure contact terminal is attached to the plate-shaped housing and when the electric wire is pressure-contacted to the pressure contact terminal. Therefore, the press contact terminal can be easily attached to the plate-shaped housing, and the electric wire can be securely pressed to the press contact terminal.

  According to the second aspect of the present invention, since the protruding amount of the convex portion is equal to the thickness of the substrate, when the press contact terminal is attached to the plate-like housing, the convex portion can reliably support the protruding portion described above. For this reason, it is possible to reliably prevent the bottom plate portion from being inclined with respect to the substrate and to prevent buckling of the press contact blade and the like when the press contact is made to the press contact terminal. Therefore, it is possible to press the electric wire more securely to the press contact terminal.

  According to the third aspect of the present invention, since the bent portion is positioned between the pair of convex portions, it is possible to prevent the displacement of the press contact terminal within the terminal accommodating groove.

  In the present invention according to claim 4, the thickness of the plate-shaped housing in the direction intersecting the surface of the main body is larger than the connector housing that press-fits the press-contact terminal into the terminal housing chamber along the longitudinal direction of the press-contact terminal and the terminal housing chamber. Can be suppressed. For this reason, it is possible to reduce the size of the plate-like housing, that is, the size of the connector.

  According to the fifth aspect of the present invention, the second center line and the third center line that bisects the width of the press contact blade can be positioned on the same straight line. For this reason, the press contact terminal can be prevented from expanding in the width direction. Therefore, the size of the press contact terminal can be reduced.

This one outer wall is connected to the end of the electric wire connecting portion 19 in the longitudinal direction Y of the substrate 17 described later. One end portion of the terminal fitting 32 of the mating connector 30 enters the cylindrical portion 21. One end of the elastic spring piece 22 is connected to the other outer wall of the cylindrical portion 21 and extends from the other outer wall toward the substrate 17 described above. The elastic spring piece 22 presses one end of the terminal fitting 32 that has entered the cylinder portion 21 toward the inner surface of the cylinder portion 21.

The pair of locking spring pieces 20 are opposed to each other at an interval along the width direction X of the electrical contact portion 18, that is, the press contact terminal 3. The pair of locking spring pieces 20 intersects both the width direction X and the thickness direction Z described above in a direction in which the interval between the pair of locking spring pieces 20 gradually increases as the distance from the one outer wall increases.

  Further, the pair of locking spring pieces 20 are elastically deformable so that the edges 20a on the side away from the one outer wall described above come in contact with each other. In addition, approaching / separating means approaching or separating from each other. Further, in the neutral state that is not elastically deformed, the interval between the edges 20a of the locking spring piece 20 described above is between the protrusions 12 that protrude from the inner surface of the partition wall 9 that forms the terminal receiving groove 7 and that face each other.

Further, the length in the thickness direction Z from the substrate 17 to the edge 20a of the locking spring piece 20 is shorter than the distance in the thickness direction Z from the surface 8a of the main body 8 to the protrusion 12.

  The electric wire connection part 19 is electrically and mechanically connected to an electric wire (not shown). The electric wire is a so-called covered electric wire including a conductive core wire and an insulating covering portion that covers the core wire. As shown in FIGS. 6 and 7, the electric wire connecting portion 19 includes a substrate 17, a bent portion 26, a bottom plate portion 27, and a pair of press contact blades 23.

  The substrate 17 has a rectangular planar shape. One end of the substrate 17 in the longitudinal direction Y is connected to one outer wall of the cylindrical portion 21 of the electrical contact portion 18 described above. The substrate 27 and one outer wall of the cylindrical portion 21 are flush with each other. Further, the longitudinal direction of the substrate 17 and the longitudinal direction of the electrical contact portion 18 are parallel. A first center line P1 (indicated by a one-dot chain line in FIG. 7) that bisects the dimension of the substrate 17 in the width direction X (hereinafter referred to as width) is the dimension of the electrical contact portion 18 in the width direction X (hereinafter referred to as a dashed line). , Called a width) is parallel to a second center line P2 (indicated by a one-dot chain line in FIG. 7) that bisects the width. Further, the first center line P1 and the second center line P2 are shifted in the width direction X.

  As shown in FIGS. 7 and 8, the bent portion 26 continues to one edge 17 a in the width direction X of the substrate 17. The bent portion 26 is bent along the longitudinal direction Y at the center in the width direction X.

  The bottom plate portion 27 includes a main body portion 28 having a rectangular planar shape and a pair of projecting portions 29 protruding from the edge of the main body portion 28, and the planar shape is formed in a rectangular shape. The bent portion 26 is connected to one edge in the width direction X of the main body portion 28 of the bottom plate portion 27. As shown in FIG. 8, the main body portion 28 of the bottom plate portion 27 is overlapped with the substrate 17 by bending the bent portion 26. As described above, the bent portion of the bottom plate portion 27 is bent and overlaps the substrate 17. Further, when overlapped with the substrate 17, both edges in the width direction X of the main body 28 overlap with both edges in the width direction X of the substrate 17.

  As shown in FIGS. 9 and 10, the protruding portion 29 protrudes outside the press contact terminal 3 along the width direction X from one edge in the width direction X of the main body portion 28 of the bottom plate portion 27 where the bent portions 26 are continuous. ing. Therefore, as shown in FIG. 9, the protruding portion 29 protrudes from the one edge 17 a in the width direction X of the substrate 17 to the outside of the press contact terminal 3. The pair of projecting portions 29 are arranged along the longitudinal direction Y of the bottom plate portion 27 with a space therebetween. In addition, the pair of projecting portions 29 positions the bent portion 26 between each other, and is disposed with a space from the bent portion 26.

  As shown in FIGS. 10 and 11, the press contact blade 23 is formed in a plate shape and is connected to both ends in the longitudinal direction Y of the main body portion 28 and the protruding portion 29 of the bottom plate portion 27, and stands from the bottom plate portion 27. Has been established. For this reason, the press contact blade 23 is disposed on the substrate 17. The pair of press contact blades 23 are arranged at intervals along the longitudinal direction Y of the substrate 17. The press contact blade 23 is provided with a slit 24.

  The slit 24 extends linearly from the edge of the press contact blade 23 away from the substrate 17 toward the substrate 17, and cuts out the press contact blade 23. The slit 24 is provided at the center in the width direction X of the press contact blade 23. Further, a third center line P3 (indicated by a one-dot chain line in FIG. 7) that bisects the dimension in the width direction X (hereinafter referred to as width) of the press contact blade 23 is the same as the above-described second center line P2. It is arranged on the same straight line.

  In the press contact blade 23, an electric wire is press-fitted into the slit 24, and the inner edge of the slit 24 cuts the covering portion and comes into contact with the core wire. The pressure contact blade 23 and the wire connection portion 19, that is, the pressure contact terminal 3 are in pressure contact with the wire and are electrically and mechanically connected to the wire.

  The connector 1 having the above-described configuration is assembled as follows. The surface 8a of the main body 8 and the surface of the substrate 17 are parallel to each other, and the press contact terminal 3 is brought close to the plate-like housing 2 along an arrow K perpendicular to (intersects) the surface 8a of the main body 8. Press fit into the groove 7. The arrow K is parallel to the thickness direction Z. For this reason, the press contact terminal 3 is press-fitted into the terminal receiving groove 7 along a direction orthogonal (crossing) to the surface 8 a of the main body 8 of the plate-like housing 2. At this time, the locking spring piece 20 is positioned between the pair of ribs 13 of the terminal fixing portion 11, and the locking spring piece 20 is arranged with the protruding portion 12 along the arrow K, that is, the thickness direction Z, and the protruding portion 25 and the protruding portion 25. The parts 29 are arranged along the thickness direction Z.

  When the press contact terminal 3 is brought close to the plate-like housing 2 along the arrow K and press-fitted into the terminal receiving groove 7, the edge 20 a of the locking spring piece 20 contacts the tapered surface 14 of the protrusion 12. When the press contact terminal 3 is further press-fitted into the terminal accommodating groove 7, the edge 20a moves on the tapered surface 14, and the locking spring piece 20 is elastically deformed in a direction in which the edges 20a approach each other. When the edge 20a exceeds the protrusion 12, the locking spring piece 20 returns to the neutral state by the elastic restoring force in the direction in which the edges 20a are separated from each other.

  Thus, the locking spring piece 20 is locked to the inner surface of the partition wall 9 in a manner surrounded by the pair of ribs 13, the protrusion 12, and the main body 8. That is, the protrusion 12 positions the locking spring piece 20 between the main body 8 and the protrusion 12. Thus, as shown in FIG. 10, the press contact terminal 3 is attached to each plate-like housing 2. When the press contact terminal 3 is attached to the plate-like housing 2, as shown in FIG. 10, the press contact terminal 3 protruding portion 29 in the terminal receiving groove 7 overlaps the convex portion 25, and the convex portion 25 contacts the protruding portion 29.

  And an electric wire is press-contacted to the press contact blade 23 of the press contact terminal 3 attached to each plate-shaped housing 2. Then, the locking portions 16 of the plate-shaped housing 2 are locked to each other, and the locking portion 16 of the plate-shaped housing 2 and the locking portion 6 of the cover 4 which are located on the upper side in FIG. The cover 4 and the plate-shaped housing 2 are fixed to each other. At this time, the cover 4 and the main body 8 of the plate-like housing 2 are made parallel to each other. In this way, the connector 1 is assembled and fitted with the mating connector 30 described above. In this way, the connector 1 is fitted with the mating connector 30 or the like to form a wire harness routed in an automobile or the like, and transmits desired power, signals, or the like of each electronic device of the automobile.

  According to the present embodiment, the press contact terminal 3 includes the bent portion 26 connected to the substrate 17, the bottom plate portion 27 connected to the bent portion 26 and superimposed on the substrate 17, and the press contact blade 23 erected from the bottom plate portion 27. . Thus, the press contact terminal 3 is not provided with a pair of side walls that are connected to the press contact blade 23 and the substrate 17. For this reason, especially the dimension of the width direction X of the press-contact terminal 3 can be shortened. Therefore, it is possible to reduce the size of the pressure contact terminal 3, that is, the size of the connector 1. Further, since the side wall is not provided, the work of bending the sheet metal to form the press contact terminal 3 is facilitated, and the productivity of the press contact terminal 3 is improved.

  Further, the bottom plate portion 27 is provided with a protruding portion 29 protruding from one edge 17a in the width direction X of the substrate 17, and the protruding portion 25 that protrudes from the surface 8a of the main body portion 8 and contacts the protruding portion 29 on the plate-like housing 2. Is provided. For this reason, when the press contact terminal 3 is attached to the plate-shaped housing 2, the protrusion 29 described above is supported by the protrusion 25. For this reason, when the electric wire is press-contacted to the press contact terminal 3, the bottom plate portion 27 can be prevented from being inclined with respect to the substrate 17, and the press contact blade 23 and the like can be prevented from buckling. Therefore, it is possible to reliably press the electric wire to the press contact terminal 3.

  Furthermore, the rigidity of the plate-shaped housing 2 is improved by the convex portions 25 protruding from the surface 8a of the main body portion 8 as the bottom surface of the terminal receiving groove 7 of the plate-shaped housing 2. For this reason, if the rigidity is kept the same as that without the convex portion 25, the plate-like housing 2 can be made smaller than that without the convex portion 25. That is, the connector 1 can be miniaturized.

  Further, since the rigidity of the plate-shaped housing 2 is improved by the convex portion 25, the plate-shaped housing 2 is elastically deformed when the press contact terminal 3 is attached to the plate housing 2 or when an electric wire is press-contacted to the press contact terminal 3. Can be prevented. Therefore, the press contact terminal 3 can be easily attached to the plate-shaped housing 2, and the electric wire can be securely pressed to the press contact terminal 3.

  Since the protrusion amount L of the convex portion 25 is equal to the thickness T of the substrate 17, when the press contact terminal 3 is attached to the plate-like housing 2, the convex portion 25 can reliably support the above-described protruding portion 29. For this reason, when the electric wire is press-contacted to the press contact terminal 3, the bottom plate portion 27 can be reliably prevented from being inclined with respect to the substrate 17, and the press contact blade 23 and the like can be reliably prevented from buckling. Therefore, it is possible to press the electric wire to the press contact terminal 3 more reliably.

  Since the bent portion 26 is positioned between the pair of convex portions 25, the displacement of the press contact terminal 3 in the terminal accommodating groove 7 can be prevented.

  The press contact terminal 3 is press-fitted into the terminal receiving groove 7 along a direction orthogonal (crossing) to the surface 8 a of the main body 8 of the plate-like housing 2. For this reason, the thickness of the plate-shaped housing 2 in the direction K perpendicular to (intersects with) the surface 8a of the main body portion 8 can be suppressed from the insulator that press-fits the terminal fitting into the terminal accommodating chamber along the longitudinal direction. For this reason, it is possible to reliably reduce the size of the plate-like housing 2, that is, the size of the connector 1.

  The first center line P1 that bisects the width of the substrate 17 and the second center line P2 that bisects the width of the electrical contact portion 18 are shifted in the width direction X. For this reason, the second center line P2 and the third center line P3 that bisects the width of the press contact blade 23 can be positioned on the same straight line. Therefore, the press contact terminal 3 can be prevented from expanding in the width direction. Accordingly, the size of the pressure contact terminal 3, that is, the connector 1 can be reduced.

  Locking spring pieces 20 erected from both edges of one outer wall of the electrical contact portion 18 of the press contact terminal 3 are locked to the inner surface of the partition wall 9, and the press contact terminal 3 is attached to the plate-shaped housing 2. Thus, in order to fix the press contact terminal 3 and the plate-shaped housing 2, it is not necessary to provide a locking arm or the like that elastically deforms the plate-shaped housing 2, and it is necessary to attach and detach the spacer to the plate-shaped housing 2. Does not occur. Thus, it is not necessary to provide a space in which the locking arm or the like is elastically deformed, and it is not necessary to attach or detach the spacer to / from the plate-shaped housing 2. Can be planned.

  The locking spring piece 20 that locks to the inner surface of the partition wall 9 is erected from both edges in the width direction of one outer wall of the electrical contact portion 18 of the press contact terminal 3. For this reason, even if the press contact terminal 3 is press-fitted into the terminal receiving groove 7, the press contact terminal 3 can be prevented from being inclined in the width direction X of the substrate 17 in the terminal receiving groove 7. For this reason, even if the rigidity of the press contact terminal 3 is lowered, that is, even if the press contact terminal 3 is reduced in size, it is possible to prevent the press contact terminal 3 from being unexpectedly deformed and damaged when attached to the plate-like housing 2. For this reason, it is possible to reduce the size of the press contact terminal 3 and to reduce the size of the plate-like housing 2.

  A locking spring piece 20 is provided at the center in the longitudinal direction Y of the press contact terminal 3. For this reason, the press contact terminal 3 can be prevented from being inclined in the longitudinal direction of the substrate 17 in the terminal accommodating groove 7. Even if the rigidity of the press contact terminal 3 is lowered, that is, even if the press contact terminal 3 is reduced in size, it is possible to prevent the press contact terminal 3 from being unexpectedly deformed and damaged when being attached to the plate-shaped housing 2. For this reason, it is possible to reliably reduce the size of the press contact terminal 3 and to reliably reduce the size of the plate-like housing 2.

  The locking spring piece 20 comes into contact with the protrusion 12, and the edge 20a of the locking spring piece 20 is once elastically deformed in a direction approaching each other. For this reason, when the press contact terminal 3 is attached to the plate-like housing 2, the locking spring piece 20 is reliably elastically deformed and is securely locked to the inner surface of the partition wall 9.

  When the press contact terminal 3 is attached to the plate-shaped housing 2, the locking spring piece 20 is positioned between the protrusion 12 and the main body 8. For this reason, when the press contact terminal 3 is attached to the plate-like housing 2, it is possible to prevent the locking spring piece 20 and the protrusion 12 from interfering and the press contact terminal 3 from falling out of the terminal receiving groove 7.

  A taper surface 14 is provided on the protrusion 12. For this reason, when press-fitting the press contact terminal 3 into the terminal accommodating groove 7, the locking spring piece 20 comes into contact with the tapered surface 14, and the locking spring piece 20 is elastically deformed in a direction in which the edge 20 a gradually approaches. For this reason, the press contact terminal 3 can be easily attached to the plate-shaped housing 2.

  A pair of ribs 13 are provided so as to protrude from the inner surface of the partition wall 9 constituting the terminal accommodating groove 7 and to position the protrusion 12 therebetween. For this reason, when the press contact terminal 3 is attached to the plate-shaped housing 2, the locking spring piece 20 is surrounded by the pair of ribs 13 and the protrusions 12. For this reason, when the terminal fitting 32 is attached to the plate-shaped housing 2, it is possible to prevent the locking spring piece 20 and the protrusion 12 from interfering with each other and the press contact terminal 3 from falling out of the terminal accommodating groove 7. Further, when the press contact terminal 3 is attached to the plate-shaped housing 2, the locking spring piece 20 and the pair of ribs 13 interfere with each other, and the press contact terminal 3 is displaced in the longitudinal direction Y within the terminal receiving groove 7. Can be prevented.

  Further, since the rib 13 described above is convex from the inner surface of the partition wall 9, the rigidity of the plate-like housing 2 is improved by the rib 13. For this reason, if the rigidity is kept the same as that without the ribs 13, the plate-shaped housing 2 can be made smaller than that without the ribs 13. That is, the connector 1 can be miniaturized.

  Furthermore, since the rigidity of the plate-shaped housing 2 is improved by the ribs 13, it is possible to prevent the plate-shaped housing 2 from being elastically deformed when the press contact terminal 3 is attached to the plate-shaped housing 2. Therefore, the press contact terminal 3 can be easily attached to the plate-like housing 2.

  In the above-described embodiment, a so-called female terminal having a cylindrical electrical contact portion 18 is shown as the press contact terminal. However, in the present invention, a so-called male terminal having a rod-like or plate-like electrical contact portion may be used as the pressure contact terminal. In the embodiment described above, the protruding portion 29 protruding from only one edge 17a in the width direction X of the substrate 17 is provided. However, in the present invention, the protruding portions 29 protruding from both edges in the width direction X of the substrate 17 may be provided.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
