The header-side holding metal fitting 24 is used to increase the strength of the header housing 21 and to attach and fix the fixed terminal 24a of the header-side holding metal fitting 24 to the above-described second circuit board 40.

  Next, the configuration of the header housing 21 will be described with reference to FIGS. 4 to 6.

  The header housing 21 is formed in a substantially box shape in which one side (the lower side in FIG. 5) is opened by a plate-shaped wall portion 21a and a peripheral wall portion 21b continuously formed in a substantially rectangular ring shape along the peripheral edge portion thereof. A concave portion 21c (see FIG. 1) is formed inside the peripheral wall portion 21b. A tapered portion 21d is formed at the lower end on the outer peripheral side of the peripheral wall portion 21b so as to be positioned upward (toward the plate-shaped wall portion 21a) toward the outside. The tapered portions 21d are formed on both longitudinal ends of the longitudinal wall portion 21e of the peripheral wall portion 21b and the entire width direction Y of the lateral wall portion 21f of the peripheral wall portion 21b. That is, the lateral direction wall portion 21f at both ends in the longitudinal direction X of the header housing 21 and the longitudinal direction end portions of the longitudinal direction wall portions 21e continuous with both ends in the width direction Y of the lateral direction wall portion 21f are viewed in a plan view. Each of the substantially U-shaped tapered portions 21d (as viewed from the rear) is formed.

  The peripheral wall portion 21b between the adjacent header-side signal terminal 22 and header-side power supply terminal 23 is curved in an R shape (inverted U shape).

  Further, the widthwise direction Y of the lateral direction wall portion 21f is formed so as to be larger than the distance between two opposing longitudinal direction wall portions 21e, and the header housing 21 is entirely viewed in plan view. It is formed in a substantially I shape.

  Next, the configuration of the header-side signal terminal 22 will be described with reference to FIGS. 7 to 9.

  The header-side signal terminal 22 is manufactured by metal molding and is a conductor. The header-side signal terminal 22 has a root portion 22 a that projects from the side surface of the header housing 21. The base portion 22a is a portion fixed to the circuit pattern 41 of the second circuit board 40 by the solder 50. 29, the upper surface of the root portion 22a extends substantially parallel to the upper surface of the header housing 21 (the outer surface of the plate-shaped wall portion 21a).

  Further, the header-side signal terminal 22 includes an inner portion 22b that is continuous with the base portion 22a. The inner portion 22b bends through the joint portion between the plate-shaped wall portion 21a and the longitudinal wall portion 21e of the header housing 21, and extends along the inner surface of the longitudinal wall portion 21e to the tip of the longitudinal wall portion 21e. It is extended.

  A recess 22c is formed on the inner surface of the inner portion 22b of the header-side signal terminal 22. In the present embodiment, the recessed portion 22c is provided with a flat rear surface 22g, inclined surfaces 22h continuously provided on both sides of the rear surface 22g in the longitudinal direction X, and continuously provided on both sides of the rear surface 22g in the vertical direction Z. The inclined surface 22i and the inclined surface 22i are formed into a substantially truncated pyramid shape. An arcuate protrusion 32k of a socket-side signal terminal 32, which will be described later, is fitted into the recess 22c.

  Further, the header-side signal terminal 22 includes a tip portion 22d that is continuous with one end of the inner portion 22b. The tip portion 22d is bent along the shape of the tip of the longitudinal wall portion 21e of the header housing 21.

  The header-side signal terminal 22 includes a locked portion 22e that is continuous with the tip portion 22d. In the present embodiment, the locked portion 22e is formed from one end to the other end of the header-side signal terminal 22 in the longitudinal direction X of the header housing 21. That is, a stepped locked portion 22e is formed over the entire width of the header-side signal terminal 22 in the width direction.

  As can be seen by comparing FIGS. 29 and 30, the locked portion 22e is more than the locking portion 32d as the step portion when the header-side signal terminal 22 is fitted into the socket-side signal terminal 32. It is inserted in the back. Therefore, the locked portion 22e contacts the locking portion 32d when the header-side signal terminal 22 is pulled out from the socket-side signal terminal 32. That is, the locked portion 22e of the header-side signal terminal 22 is locked by the locking portion 32d of the socket-side signal terminal 32. Therefore, withdrawal of the header-side signal terminal 22 from the socket-side signal terminal 32 is suppressed. That is, the header-side signal terminal 22 cannot be pulled out from the socket-side signal terminal 32 only by applying an external force smaller than a predetermined value. On the other hand, the header-side signal terminal 22 can be pulled out from the socket-side signal terminal 32 when a large external force of a predetermined value or more is applied. That is, the locked portion 22e of the header-side signal terminal 22 and the locking portion 32d of the socket-side signal terminal 32 can be unlocked by applying an external force of a predetermined value or more. It constitutes the mechanism.

  The locked portion 22e may be manufactured by rolling a base material in which the thickness of the header-side signal terminal 22 is made partially different, but it is formed by bending the base material of the header-side signal terminal 22 in the thickness direction. May be manufactured by.

  Further, the header-side signal terminal 22 includes an outer portion 22f which is continuous with the tip portion 22d via the locked portion 22e and extends along the outer surface of the longitudinal wall portion 21e. In the present embodiment, the tip end of the outer side portion 22f of the header-side signal terminal 22 is positioned by the protruding wall portion 21g provided on the outer periphery of the longitudinal wall portion 21e (peripheral wall portion 21b).

  Such a header-side signal terminal 22 can be formed by bending a band-shaped metal material having a predetermined thickness.

  Further, in the present embodiment, the header-side signal terminal 22 is arranged in the header housing 21 by insert molding. The header-side signal terminal 22 may be disposed in the header housing 21 by press-fitting the header-side signal terminal 22 into the header housing 21.

  Next, the configuration of the header-side power supply terminal 23 will be described with reference to FIGS. 10 to 12.

  The header-side power supply terminal 23 is manufactured by metal molding and is a conductor. The header-side power supply terminal 23 has a root portion 23 a protruding from the side surface of the header housing 21. The root portion 23a is a portion fixed to the circuit pattern 41 of the second circuit board 40 by the solder 50. Further, as can be seen from FIG. 31, the upper surface of the root portion 23a extends substantially parallel to the upper surface of the header housing 21 (the outer surface of the plate-shaped wall portion 21a).

  Further, the header-side power supply terminal 23 includes an inner portion 23b that is continuous with the base portion 23a. The inner portion 23b bends through the joint portion between the plate-shaped wall portion 21a and the longitudinal wall portion 21e of the header housing 21, and extends along the inner surface of the longitudinal wall portion 21e to the tip of the longitudinal wall portion 21e. It is extended.

  A recess 23c is formed on the inner surface of the inner portion 23b of the header-side power supply terminal 23. In the present embodiment, the recess 23c is provided with a flat back surface 23g, inclined surfaces 23h provided on both sides of the back surface 23g in the longitudinal direction X, and both sides of the back surface 23g in the vertical direction Z. The inclined surface 23i and the inclined surface 23i are formed into a substantially quadrangular pyramid shape. An arcuate projection 33k of a socket-side power supply terminal 33, which will be described later, fits into the recess 23c.

  Further, the header-side power supply terminal 23 includes a tip portion 23d that is continuous with one end of the inner portion 23b. The tip portion 23d is bent along the shape of the tip of the longitudinal wall portion 21e of the header housing 21.

  The header-side power supply terminal 23 includes a locked portion 23e that is continuous with the tip portion 23d. As can be seen by comparing FIGS. 31 and 32, the locked portion 23e is deeper than the locking portion 33d as the step portion when the header-side power supply terminal 23 is fitted into the socket-side power supply terminal 33. Is inserted into. Therefore, the locked portion 23e contacts the locking portion 33d when the header-side power supply terminal 23 is pulled out from the socket-side power supply terminal 33. That is, the locked portion 23e of the header-side power supply terminal 23 is locked by the locking portion 33d of the socket-side power supply terminal 33. Therefore, withdrawal of the header-side power supply terminal 23 from the socket-side power supply terminal 33 is suppressed. That is, the header-side power supply terminal 23 cannot be pulled out from the socket-side power supply terminal 33 only by applying an external force smaller than a predetermined value. On the other hand, the header-side power supply terminal 23 can be pulled out from the socket-side power supply terminal 33 when a large external force of a predetermined value or more is applied. That is, the locked portion 23e of the header-side power supply terminal 23 and the locking portion 33d of the socket-side power supply terminal 33 can be unlocked by applying an external force of a predetermined value or more. It constitutes the mechanism.

  The locked portion 23e may be manufactured by rolling a base material that partially changes the thickness of the header-side power supply terminal 23, but is formed by bending the base material of the header-side power supply terminal 23 in the thickness direction. May be manufactured by.

  Further, the header-side power supply terminal 23 includes an outer portion 23f which is continuous with the tip portion 23d via the locked portion 23e and extends along the outer surface of the longitudinal wall portion 21e. Furthermore, in the present embodiment, the tip of the outer portion 23f of the header-side power supply terminal 23 is positioned by the protruding wall portion 21h that is provided so as to protrude on the outer periphery of the longitudinal wall portion 21e (peripheral wall portion 21b).

  As described above, in the present embodiment, the side cross-sectional shape of the header-side signal terminal 22 and the side cross-sectional shape of the header-side power supply terminal 23 are substantially the same (FIGS. 9A and 12A). )reference).

  Moreover, as described above, the header-side signal terminal 22 and the header-side power supply terminal 23 are arranged along the longitudinal direction X of the header housing 21. In the present embodiment, the header-side power supply terminal 23 is formed such that the width of the header housing 21 along the longitudinal direction X is wider than the width of the header-side signal terminal 22 along the longitudinal direction X. ing.

  That is, in the present embodiment, the header-side signal terminal 22 having a smaller width in the longitudinal direction X of the header housing 21 than the header-side power supply terminal 23 is provided. In this embodiment, all the header-side signal terminals 22 are narrower in width in the longitudinal direction X of the header housing 21 than the header-side power supply terminals 23.

  As described above, since the width of the header-side power supply terminal 23 along the longitudinal direction X of the header housing 21 is widened, a recessed portion having a concave shape is formed at the center of the root portion 23a in the longitudinal direction X. 23j is formed. By forming the concave portion 23j, it is possible to increase the length of the contour line in contact with the circuit pattern of the root portion 23a while suppressing an increase in the amount of protrusion of the root portion 23a. Also, the shape of the contour line can be made more complicated. By doing so, as compared with the case where the recess 23j is not formed, the base portion 23a and the circuit pattern 41 when fixing the wider header-side power supply terminal 23 to the circuit pattern 41 of the second circuit board 40 with the solder 50 are provided. The fixing strength with the solder 50 is increased.

  Further, on the inner surface of the inner portion 23b of the header-side power supply terminal 23, two concave portions 23c are formed along the longitudinal direction X, and two arc-shaped projections of the socket-side power supply terminal 33 described later are formed. The parts 33k are fitted in each other.

  Further, in the present embodiment, the locked portion 23e is formed from one end to the other end of the header-side power supply terminal 23 in the longitudinal direction X of the header housing 21. That is, the stepped locked portion 23e is formed over the entire width of the wide header-side power supply terminal 23 in the width direction. By doing so, the locking force by the locked portion 23e of the header-side power supply terminal 23 and the locking portion 33d of the socket-side power supply terminal 33 can be improved. Further, even when the header 20 and the socket 30 are repeatedly inserted and removed, the locked portion 23e is less likely to wear, so that the life of the product can be extended.

  Such a header-side power supply terminal 23 can be formed by bending a band-shaped metal material having a predetermined thickness.

  Further, in this embodiment, the header-side power supply terminal 23 is arranged in the header housing 21 by insert molding. The header-side power supply terminal 23 may be disposed in the header housing 21 by press-fitting the header-side power supply terminal 23 into the header housing 21.

The facing part 32z includes a flat part 32g, a first oblique part 32h, a second arcuate part 32i, a second oblique part 32j, an arcuate protrusion 32k, and a tip part 32m, which will be described next. The facing portion 32z is specifically as follows.

  The facing portion 32z includes a flat portion 32g that is continuous with the lower end of the inclined portion 32f. As shown in FIG. 29, the flat portion 32g extends along the main surface M of the first circuit board 60 so as to be separated from the falling portion 32e. However, the flat portion 32g does not have to be parallel to the main surface M. The flat portion 32g is provided to increase the spring length of the spring portion described later.

  As shown in FIG. 29, the facing portion 32z includes a first diagonal portion 32h which is continuous with the flat portion 32g and extends diagonally with respect to the main surface M of the first circuit board 60. The first diagonal portion 32h extends away from the falling portion 32e as the distance from the first circuit board 60 increases. The first diagonal portion 32h is continuous with the second arcuate portion 32i. The second arcuate portion 32i is a curved portion that projects away from the falling portion 32e. The second arc-shaped portion 32i is continuous with the second diagonal portion 32j that extends diagonally with respect to the main surface M of the first circuit board 60. The second diagonal portion 32j extends so as to approach the falling portion 32e as the distance from the first circuit board 60 increases. Therefore, the second diagonal portion 32j is positioned above the first diagonal portion 32h.

  As shown in FIG. 29, the facing portion 32z is provided with an arcuate protrusion 32k whose one end is continuous with the upper end of the second diagonal portion 32j. The arcuate protrusion 32k has a front end surface 32r and inclined surfaces 32s that are continuously provided on both sides of the front end surface 32r in the longitudinal direction X, and is formed in a protruding shape protruding in a substantially trapezoidal shape in a horizontal sectional view. (See FIG. 26B).

  As shown in FIG. 29, the arcuate protrusion 32k fits into the recess 22c of the header-side signal terminal 22. The other end of the arcuate protrusion 32k is continuous with the tip 32m. The tip portion 32m extends substantially parallel to the second diagonal portion 32j. As can be seen from FIGS. 29 and 30, the facing portion 32z (32g, 32h, 32i, 32j, 32k, 32m) is continuous with the lower end of the inclined portion 32f and faces the falling portion 32e as a whole.

  In this embodiment, when the header 20 and the socket 30 are fitted to each other, as shown in FIG. 30, the header-side signal terminal 22 is inserted between the inverted U-shaped portion 32c and the arcuate protrusion 32k.

The spring portions (32e, 32f, 32g, 32h, 32i, 32j, 32k, 32m) are elastically deformed when the convex portion of the header-side signal terminal 22 is inserted into the concave portion of the socket-side signal terminal 32. This increases the distance between the two portions of the falling portion 32e and the inverted U-shaped portion 32c and the arcuate protrusion 32k. At this time, the locked portion 22e of the header-side signal terminal 22 is inserted below the locking portion 32d of the socket-side signal terminal 32. As a result, the arcuate protrusion 32k of the socket-side signal terminal 32 fits into the recess 22c of the header-side signal terminal 22.

  When the header-side signal terminal 22 is fitted in the socket-side signal terminal 32, a restoring force is generated in the elastically deformed spring portion. Due to this restoring force, the arcuate protrusion 32k presses the header-side signal terminal 22 against each of the falling portion 32e and the inverted U-shaped portion 32c. As a result, the header-side signal terminal 22 is sandwiched between the socket-side signal terminals 32. At this time, the header-side signal terminal 22 comes into contact with each of the inverted U-shaped portion 32c, the falling portion 32e, and the arc-shaped protrusion 32k of the socket-side signal terminal 32.

  The recess 22c of the header-side signal terminal 22 contacts the arcuate protrusion 32k of the socket-side signal terminal 32. That is, the contact portion R2 of the socket-side signal terminal 32 and the contact portion R2 of the header-side signal terminal 22 come into contact with each other.

  As described above, the header-side signal terminal 22 and the socket-side signal terminal 32 are in contact with each other at the plurality of contacts (contact point R1 and contact point R2) separated in the width direction Y. Therefore, the reliability of the electrical connection between the header-side signal terminal 22 and the socket-side signal terminal 32 is high.

  Further, in the present embodiment, one of the contact portions R2 of the socket-side signal terminal 32 and the header-side signal terminal 22 that are in contact with each other, which is one of the contact portions, is the contact portion of the header-side signal terminal 22. A recess 22c is formed in R2. The contact portion R2 of the socket-side signal terminal 32, which is the other contact portion, comes into contact with both ends of the recess 22c in the longitudinal direction X of the socket housing 31.

  Specifically, as shown in FIG. 33 (a), when the arcuate protrusion 32k of the socket-side signal terminal 32 is fitted into the recess 22c, the tip end surface 32r and the inclined surface 32s of the arcuate protrusion 32k. Boundary portions with and are in contact with the inclined surface 22h, respectively. As described above, in this embodiment, the contact portion R2 of the socket-side signal terminal 32 contacts the contact portion R2 of the header-side signal terminal 22 at two points (contact point C1 and contact point C2).

  In addition to the contact points R1 and R2, the boundary portion between the flat portion 32g and the first slanted portion 32h contacts the first circuit board 60 at the contact point R5 due to the elastic deformation of the spring portion. In some cases.

  In this way, the header-side signal terminal 22 and the socket-side signal terminal 32 of this embodiment are in contact with each other at a plurality of contacts that are separated in the width direction Y. However, the header-side signal terminal and the socket-side signal terminal of the present invention are in contact with each other, for example, at only one contact point between the inner surface of the header-side signal terminal and the facing portion of the socket-side signal terminal.

As shown in FIG. 31, the flat portion 33g extends along the main surface M of the first circuit board 60 away from the falling portion 33e. However, the flat portion 33g does not have to be parallel to the main surface M. The flat portion 33g is provided to increase the spring length of the spring portion described later.

  As shown in FIG. 31, the facing portion 33z is provided with a first diagonal portion 33h which is continuous with the flat portion 33g and extends diagonally with respect to the main surface M of the first circuit board 60. The first diagonal portion 33h extends away from the falling portion 33e as the distance from the first circuit board 60 increases. The first diagonal portion 33h is continuous with the second arcuate portion 33i. The second arcuate portion 33i is a curved portion that projects away from the falling portion 33e. The second arcuate portion 33i is continuous with the second diagonal portion 33j extending diagonally with respect to the main surface M of the first circuit board 60.

That is, the contact portion R4 of the socket-side power supply terminal 33 and the contact portion R4 of the header-side power supply terminal 23 come into contact with each other.

  In this way, the header-side power supply terminal 23 and the socket-side power supply terminal 33 are in contact with each other at the plurality of contacts (contact point R3 and contact point R4) separated in the width direction Y. Therefore, the reliability of the electrical connection between the header-side power supply terminal 23 and the socket-side power supply terminal 33 is high.

  As a result, the cross-sectional area of the terminal can be increased, and the current capacity can be increased.

  The header-side power supply terminal 23 has a stepped locked portion 23e that is locked to the socket-side power supply terminal 33, and the locked portion 23e is the header of the header-side power supply terminal 23. The housing 21 is formed from one end to the other end in the longitudinal direction X.

  As a result, the lock force can be improved, and wear is less likely to occur when the insertion and removal are repeated, so that the life of the product can be extended.

  Further, it has a header-side power supply terminal 23 arranged outside the header-side signal terminal 22 in the longitudinal direction X of the header housing 21. In this way, by disposing the header-side power supply terminal, which generates a large amount of heat, outside the header housing in the longitudinal direction, it becomes possible to improve heat dissipation.

  Further, the header housing 21 is provided with a header-side holding metal fitting 24. The header-side holding metal fitting 24 has a fixed terminal 24a to be soldered to the circuit pattern 41 formed on the second circuit board 40. Further, the header-side power supply terminal 23 has a root portion 23a to be soldered to the circuit pattern 41 formed on the second circuit board 40. The fixed terminal 24a and the root portion 23a are soldered to the common circuit pattern 41b.

  By doing so, the circuit pattern to which the header-side holding metal fitting 24 is fixed can also be used as a heat dissipation plate for the heat generated by the header-side power supply terminal 23, and the heat dissipation can be further improved.

  The header-side holding metal fitting 24 and the header-side power supply terminal 23 are arranged adjacent to each other.

  This makes it possible to improve heat dissipation and to prevent the wiring shape of the circuit pattern from becoming complicated.

  Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made.

  For example, in the above-described embodiment, the header 20 is formed so as to be point-symmetric with respect to the center of the header 20 in plan view, and the socket 30 is pointed with respect to the center of the socket 30 in plan view. A connector (a connector having no polarity) formed symmetrically is illustrated.

  However, it is also possible to apply the present invention to a connector having a polarity (a connector that does not have the same shape when rotated by 180 degrees).

  It is also possible to have a configuration in which the header-side holding metal fitting and the socket-side holding metal fitting are engaged with each other while the header 20 and the socket 30 are fitted together.

  Further, the specifications of the socket housing, the header housing, and other details (shape, size, layout, etc.) can be appropriately changed.
