Distance) to almost the same. Furthermore, the length of the longitudinal direction wall portion 21e in the longitudinal direction X is the distance between two opposing lateral direction wall portions 21f (from the outer surface 21m of one lateral direction wall portion 21f to the other lateral direction wall portion 21f). It is formed so as to be almost the same as the outer surface 21 m).

As described above, in the present embodiment, the header housing 21 is formed in a generally rectangular shape in plan view.

Next, the configuration of the header-side signal terminal 22 will be described with reference to FIGS. 7 and 8.

The header-side signal terminal 22 is manufactured by metal molding and is a conductor. The header-side signal terminal 22 includes a root portion (first header-terminal-side fixing portion) 22a that projects from the side surface of the header housing 21. The root portion 22a is a portion fixed to the circuit pattern 41 of the second circuit board 40 by the solder 50. 23, the upper surface of the root portion 22a extends substantially parallel to the upper surface of the header housing 21 (the outer surface 21j 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 passes through the joint between the plate-shaped wall portion 21a and the longitudinal wall portion 21e of the header housing 21 while bending, and extends along the inner surface 21n of the longitudinal wall portion 21e to the tip of the longitudinal wall portion 21e.

That is, the 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. 23 and 24, this locked portion 22e is more than the locking portion 32d as a stepped 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 comes into contact with 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, pulling out 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 thicknesses of the header-side signal terminals 22 are partially different, but molding to bend the base material of the header-side signal terminals 22 in the thickness direction. May be manufactured by.

Further, the header-side signal terminal 22 includes an outer portion 22f that is continuous with the tip portion 22d via the locked portion 22e and extends along the outer surface 21k of the longitudinal wall portion 21e.

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

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

Further, the header-side power supply terminal 23 includes a locked portion 23d that is continuous with the tip portion 23c. As can be seen by comparing FIGS. 25 and 26, the locked portion 23d 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 23d 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 23d of the header-side power supply terminal 23 is locked by the locking portion 33d of the socket-side power supply terminal 33. Therefore, the header side power supply terminal 23 is prevented from being pulled out from the socket side power supply terminal 33. 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 23d of the header-side power supply terminal 23 and the locking portion 33d of the socket-side power supply terminal 33 can be unlocked from each other by applying an external force of a predetermined value or more. It constitutes the mechanism.

The locked portion 23d 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 23e which is continuous with the locked portion 23d and is arranged along the outer surface of the header housing 21. The outer portion 23e extends from the locked portion 23d to the plate-shaped wall portion 21a along the outer surface 21k of the longitudinal wall portion 21e.

Further, the header-side power supply terminal 23 is provided with a root portion (second header terminal-side fixing portion) 23f which is continuous with the outer side portion 23e and projects from the side surface of the header housing 21. The root portion 23f 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. 25, the upper surface of the root portion 23f extends substantially parallel to the upper surface of the header housing 21 (the outer surface 21j of the plate-shaped wall portion 21a).

In the present embodiment, the width of the root portion 23f along the longitudinal direction X of the header housing 21 is larger than the width of the outer portion 23e (other part of the header-side power supply terminal 23) along the longitudinal direction X. It is formed to be narrow. The root portion 23f is continuously provided on the outer side portion of the outer side portion 23e in the longitudinal direction X (the side away from the adjacent header-side signal terminal 22 in the X direction).

That is, with the header-side signal terminal 22 and the header-side power supply terminal 23 arranged in the header housing 21, the root portion (first header terminal-side fixing portion) 22a and the root portion (second header terminal-side fixing portion) are provided. ) 23f is the distance between the contact portion (first socket terminal side contact portion) R1 and R2 of the header side signal terminal 32 and the contact portion (second header terminal) of the header side power supply terminal 23 described later. It is designed to be larger than the distance between the side fixing portions) R3 and R4.

By doing so, the insulation distance between the header-side power supply terminal 23 and the header-side signal terminal 22 is lengthened to ensure insulation.

As shown in FIG. 23, flat portion 32g extends along main surface M of first circuit board 60 away from 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. 23, 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 arcuate portion 32i is continuous with the second diagonal portion 32j extending 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.

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.

Specifically, as shown in FIGS. 23 and 24, the tip portion 22d of the header-side signal terminal 22 contacts the falling portion 32e of the socket-side signal terminal 32.

That is, the contact portion (first socket terminal side contact portion) R2 of the socket side signal terminal 32 and the contact portion (first header terminal side contact portion) R2 of the header side signal terminal 22 come into contact with each other. ..

In this way, the header-side signal terminal 22 and the socket-side signal terminal 32 are in contact with each other at a plurality of contacts (two contact points R1 and 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 contact portion R2 of the header-side signal terminal 22, which are in contact with each other, 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, when the arcuate protrusion 32k of the socket-side signal terminal 32 is fitted into the recess 22c, the boundary between the tip end surface 32r of the arcuate protrusion 32k and the inclined surface 32s becomes the inclined surface 22h.

As described above, the locking portion 33d functions as a portion that suppresses the movement of the locked portion 23d when the header-side power supply terminal 23 is pulled out from the socket-side power supply terminal 33. That is, the locking portion 33d of the socket-side power supply terminal 33 can contact the locked portion 23d of the header-side power supply terminal 23 and lock the locked portion 23d. The locking portion 33d of the socket-side power supply terminal 33 and the locked portion 23d of the header-side power supply terminal 23 constitute a locking mechanism capable of releasing the locking by applying an external force of a predetermined value or more. ing.

The locking portion 33d may be manufactured by rolling a base material that partially changes the thickness of the socket-side power supply terminal 33, but it may be formed by bending the base material of the socket-side power supply terminal 33 in the thickness direction. It may be manufactured.

Further, the socket-side power supply terminal 33 has a falling portion 33e which is continuous with the locking portion 33d and extends substantially parallel to the rising portion 33b.

The socket-side power supply terminal 33 includes an inclined portion 33f that is continuous with the lower end of the falling portion 33e. The socket-side power supply terminal 33 may include the first arc-shaped portion 33f instead of the inclined portion 33f.

As shown in FIGS. 25 and 26, the socket-side power supply terminal 33 includes a facing portion 33z that is continuous with the inclined portion 33f. The facing portion 33z includes a flat portion 33g, a first diagonal portion 33h, a second arcuate portion 33i, a second diagonal portion 33j, an arcuate protrusion 33k, and a tip portion 33m, which will be described next. The facing portion 33z is specifically as follows.

The facing portion 33z includes a flat portion 33g that is continuous with the lower end of the inclined portion 33f. As shown in FIG. 25, flat portion 33g extends along main surface M of first circuit board 60 so as to be separated from 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. 25, the facing portion 33z includes 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 arc-shaped 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. The second diagonal portion 33j extends so as to approach the falling portion 33e as the distance from the first circuit board 60 increases. Therefore, the second diagonal portion 33j is positioned above the first diagonal portion 33h.

As shown in FIG. 35, the facing portion 33z is provided with an arcuate protrusion 33k whose one end is continuous to the upper end of the second diagonal portion 33j. The arcuate protrusion 33k has a front end surface 33v and inclined surfaces 33w that are continuously provided on both sides of the front end surface 33v in the longitudinal direction X, and is formed in a protruding shape protruding in a substantially trapezoidal shape in a horizontal cross-sectional view. Has been done.

As shown in FIG. 25, the arcuate protrusion 33k fits into the recess 23b of the header-side power supply terminal 23. The other end of the arcuate protrusion 33k is continuous with the tip 33m. The tip portion 33m extends substantially parallel to the second diagonal portion 33j. As can be seen from FIGS. 25 and 26, the facing portion 33z (33g, 33h, 33i, 33j, 33k, 33m) is continuous with the lower end of the inclined portion 33f and faces the falling portion 33e as a whole.

Thus, in the present embodiment, the side surface shape of the socket side signal terminal 32 and the side surface shape of the socket side power supply terminal 33 are substantially the same shape (see FIGS. 18A and 20A). ).

In the present embodiment, when the header 20 and the socket 30 are fitted to each other, as shown in FIG. 26, the header-side power supply terminal 23, like the socket-side signal terminal 32, has an inverted U-shaped portion. It is inserted between 33c and the arcuate protrusion 33k. At this time, the falling portion 33e, the inclined portion 33f, the flat portion 33g, the first diagonal portion 33h, the arcuate portion 33i, the second diagonal portion 33j, the arcuate projection portion 33k, and the tip portion 33m are integrated. Function as a spring part. The spring portions (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) are elastically deformed when the protrusion of the header-side power supply terminal 23 is inserted into the recess of the socket-side power supply terminal 33.

In the present embodiment, the width (width along the longitudinal direction X) in the portion from the inclined portion 33f to the tip portion 33m is the rising portion 33b, the inverted U-shaped portion 33c, the locking portion 33d, and the falling portion 33e. Is narrower than the width (width along the longitudinal direction X). Therefore, in the spring portion (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m), the portion from the inclined portion 33f to the tip portion 33m is particularly easily elastically deformed.

When the spring portions (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) are elastically deformed, the two portions of the falling portion 33e and the inverted U-shaped portion 33c and the arc-shaped protrusion portion 33k are formed. The distance between them increases. At this time, the locked portion 23d of the header-side power supply terminal 23 is inserted below the locking portion 33d of the socket-side power supply terminal 33. As a result, the arcuate protrusion 33k of the socket-side power supply terminal 33 fits into the recess 23b of the header-side power supply terminal 23.

When the header-side power supply terminal 23 is fitted in the socket-side power supply terminal 33, a restoring force is generated in the elastically deformed spring portion. Due to this restoring force, the arcuate protrusion 33k presses the header-side power supply terminal 23 against each of the falling portion 33e and the inverted U-shaped portion 33c. As a result, the header-side power supply terminal 23 is sandwiched between the socket-side power supply terminals 33. At this time, the header-side power supply terminal 23 contacts each of the inverted U-shaped portion 33c, the falling portion 33e, and the arc-shaped projection portion 33k of the socket-side power supply terminal 33.

Specifically, as shown in FIGS. 25 and 26, the tip end portion 23 c of the header-side power supply terminal 23 contacts the falling portion 33 e of the socket-side power supply terminal 33. That is, the contact part (second socket terminal side contact part) R3 of the socket side power supply terminal 33 and the contact part (second header terminal side contact part) R3 of the header side power supply terminal 23 come into contact with each other. ..

The recess 23b of the header-side power supply terminal 23 contacts the arcuate projection 33k of the socket-side power supply terminal 33. That is, the contact part (second socket terminal side contact part) R4 of the socket side power supply terminal 33 and the contact part (second header terminal side contact part) 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 a plurality of contacts (two contact points R3 and 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.

The contact portion R3 and the contact portion R4 provided at two positions of the socket-side power supply terminal 33 are closer to the root portion (second socket terminal side fixing portion) 33a than the contact portion R4 is. positioned.

In the present embodiment, the cross-sectional area of the contact part R3 located on the side closer to the root part (second socket terminal side fixing part) 33a of the contact part R3 and the contact part R4 is located on the other side. It is designed to be larger than the cross-sectional area of R4. Such a configuration can be obtained, for example, by appropriately setting the width (width along the longitudinal direction X) and thickness (plate thickness) of the contact portion R3 and the contact portion R4 of the socket-side power supply terminal 33.

In the present embodiment, the width (width along the longitudinal direction X) of the contact portion R3 of the socket-side power supply terminal 33 is made wider than the width (width along the longitudinal direction X) of the contact portion R4. ..

Further, in the present embodiment, the root portion 33a is formed such that the width of the socket housing 31 along the longitudinal direction X is narrower than the width of the rising portion 33b along the longitudinal direction X.

Distance between the socket side signal terminal 32 (first socket terminal side contact section) R1 and R2 and the socket side power terminal 33 (second socket). It is designed to be larger than the distance between the terminal side contact portions) R3 and R4.

In this way, the insulation distance between the socket-side power supply terminal (second socket terminal) 33 and the socket-side signal terminal (first socket terminal) 32 (root portion 33a and root portion 32a that are adjacent to each other in the X direction). Distance) can be lengthened.

The width of the root portion (second socket terminal side fixing portion) 33a is reduced without causing the root portion (second socket terminal side fixing portion) 33a to project to the outside in the longitudinal direction X beyond the rising portion 33b. Therefore, the insulation distance can be increased.
