One header-side signal terminal group G3 and one header-side power supply terminal 23 arranged side by side on the other side of the width direction (lateral direction) Y of the header housing 21 constitute a header-side terminal group G1. ing.

Thus, in the present embodiment, the header housing 21 includes the header side signal terminal group G3 and the header side power supply terminals 23 arranged along the longitudinal direction X of the header housing 21 . Two rows (multiple rows) of terminal groups G1 are arranged.

In this embodiment, in the header side terminal group G1 formed on one side of the header housing 21 in the width direction (lateral direction) Y, the header side power supply terminals are provided on one side of the header housing 21 in the longitudinal direction X. 23 are arranged. In the header-side terminal group G1 formed on the other side of the header housing 21 in the width direction (lateral direction) Y, the header-side power supply terminals 23 are arranged on the other side of the header housing 21 in the longitudinal direction X. there is

Thus, in this embodiment, the header-side power supply terminal 23 is located on one side in the longitudinal direction X of the header housing 21 and on one side in the width direction (lateral direction) Y, and in the longitudinal direction X of the header housing 21 . They are arranged only at two locations on the other side and the other side in the width direction (transverse direction) Y.

In other words, only two header-side power supply terminals 23 are arranged in the header housing 21 , and the two header-side power supply terminals 23 are arranged at diagonal portions of the rectangular (rectangular) header housing 21 . ing.

At this time, the two header-side power supply terminals 23 are in a state in which the header-side holding metal fittings 24 are arranged at both ends of the header housing 21 in the longitudinal direction X (the header housing 21 is positioned closer to the header-side power supply terminals 23 than the header-side power supply terminals 23 are). It is arranged in the header housing 21 with the header-side holding fittings 24 positioned outside in the longitudinal direction X).

Furthermore, in the present embodiment, the header-side signal terminal group G3 on one long side and the header-side signal terminal group G3 on the other long side are formed in a state of being shifted in the longitudinal direction X of the header housing 21. I'm trying to be

Specifically, the headers are arranged such that one header-side signal terminal group G3 is formed in a state of being shifted by one pitch in the longitudinal direction X of the header housing 21 with respect to the other header-side signal terminal group G3. A side signal terminal 22 is arranged.

By doing so, the header-side signal terminals 22 arranged at one end in the X direction of one header-side signal terminal group G3 and the header-side signals arranged at the other X-direction end of the other header-side signal terminal group G3 The header-side signal terminals 22 other than the header-side signal terminals 22 can be arranged so as to face each other in the Y direction.

A power supply terminal 23 is arranged.

Moreover, the header-side power supply terminal 23 that constitutes one header-side terminal group G1 overlaps in the Y-direction with the header-side signal terminal 22 arranged at the other end of the other header-side signal terminal group G3 in the X direction. are placed.

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

The header housing 21 is formed in a substantially box-like shape with one side (lower side in FIG. 5) opened by a plate-like wall portion 21a and a peripheral wall portion 21b continuously formed in a substantially rectangular annular shape along the periphery thereof. It is

A concave portion 21c (see FIG. 4) is formed inside the peripheral wall portion 21b. A tapered portion 21d is formed at the lower end of the peripheral wall portion 21b on the outer peripheral side so as to be positioned upward (toward the plate-like wall portion 21a) toward the outside.

The peripheral wall portion 21b between the adjacent header-side signal terminals 22 and between the header-side signal terminal group G3 and the header-side power supply terminal 23 is curved in an R shape (inverted U shape). there is

In addition, in the present embodiment, the peripheral wall portion 21b includes a pair of longitudinal wall portions 21e facing each other in the width direction (transverse direction) Y, and a pair of transverse direction walls 21f facing each other in the longitudinal direction X. ing.

The length in the width direction Y of the lateral wall portion 21f is the distance between the two opposing longitudinal wall portions 21e (from the outer surface 21k of one longitudinal wall portion 21e to the outer surface 21k of the other longitudinal wall portion 21e). distance to). Furthermore, the length of the longitudinal direction wall 21e in the longitudinal direction X is equal to the distance between the two opposing transverse direction walls 21f (from the outer surface 21m of one transverse direction wall 21f to the other transverse direction wall 21f). distance to the outer surface 21m).

Thus, in this embodiment, the header housing 21 is generally formed in a substantially rectangular shape in plan view. Therefore, the outer surface 21k of the longitudinal direction wall portion 21e and the outer surface 21m of the lateral direction wall portion 21f are the outer surface 21h of the peripheral wall portion 21b, and the inner surface 21n of the longitudinal direction wall portion 21e and the inner surface 21p of the lateral direction wall portion 21f. is the inner surface 21i of the peripheral wall portion 21b.

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

The header-side signal terminal 22 is manufactured by metal molding and is a conductor. The header-side signal terminal 22 has a base portion (first header-terminal-side fixing portion) 22 a protruding from the side surface of the header housing 21 . The root portion 22 a is a portion fixed to the circuit pattern 41 of the second circuit board 40 by solder 50 . As can be seen from FIG. 23, the upper surface of the base portion 22a extends substantially parallel to the upper surface of the header housing 21 (the outer surface 21j of the plate-like wall portion 21a).

Moreover, the header-side signal terminal 22 has an inner portion 22b that is continuous with the base portion 22a. The inner portion 22b bends through the junction between the plate-like wall portion 21a and the longitudinal wall portion 21e of the header housing 21, and extends along the inner surface 21n of the longitudinal wall portion 21e to the tip of the longitudinal wall portion 21e. extended.

A concave portion 22c is formed on the inner surface of the inner portion 22b of the header-side signal terminal 22 . In the present embodiment, the concave portion 22c is formed in a substantially triangular prism shape with inclined surfaces 22h provided on both sides in the longitudinal direction X and inclined surfaces 22i provided on both sides in the vertical direction Z. 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 has a tip portion 22d that continues to 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 has a locked portion 22e that is continuous with the tip portion 22d. In this embodiment, the locked portion 22e is formed from one end to the other end in the longitudinal direction X of the header housing 21 in the header-side signal terminal 22 . In other words, a stepped locked portion 22e is formed over the entire width direction of the header-side signal terminal 22 .

23 and 24, when the header-side signal terminal 22 is fitted into the socket-side signal terminal 32, the locked portion 22e is more inclined than the locking portion 32d as a stepped portion. It is inserted deep inside. Therefore, locked part 22e contacts locking part 32d, when terminal 22 for the header side signals is pulled out from terminal 32 for the socket side signals. That is, locked part 22e of terminal 22 for the header side signals is stopped by locking part 32d of terminal 32 for the socket side signals. Therefore, pulling out from terminal 32 for socket side signals of terminal 22 for header side signals is controlled. 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 terminals 22 can be pulled out from the socket-side signal terminals 32 when an external force greater than or equal to a predetermined value is applied. In other words, the locked portion 22e of the header-side signal terminal 22 and the locking portion 32d of the socket-side signal terminal 32 are locks capable of unlocking each other by applying an external force greater than or equal to a predetermined value. make up the mechanism.

The locked portion 22e may be manufactured by rolling a base material that partially varies the thickness of the header-side signal terminal 22, but may be formed by bending the base material of the header-side signal terminal 22 in the thickness direction. may be manufactured by

Furthermore, the header-side signal terminal 22 has an outer portion 22f that continues to 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 tip of the outer portion 22f of the header-side signal terminal 22 is positioned by a projecting wall portion 21g projecting from the outer periphery of the longitudinal wall portion 21e (peripheral wall portion 21b).

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

Moreover, he is trying for the terminal 22 for header side signals to be arrange|positioned by the header housing 21 by insert molding in this embodiment. In addition, you may make it arrange|position the terminal 22 for header side signals in the header housing 21 by press-fitting the terminal 22 for header side signals into the header housing 21. FIG.

Next, configurations of the header-side power supply terminal 23 and the header-side holding fitting 24 will be described with reference to FIGS. 9 and 10. FIG.

The header-side power supply terminal 23 is manufactured by metal molding and is a conductor. And this terminal 23 for the header side power supplies is equipped with the inner part 23a arrange|positioned so that the inner surface of the header housing 21 may be met. The inner portion 23a extends from the junction between the plate-like wall portion 21a of the header housing 21 and the longitudinal wall portion 21e to the tip of the longitudinal wall portion 21e along the inner surface 21n of the longitudinal wall portion 21e.

And recessed part 23b is formed on the inner surface of inner part 23a of terminal 23 for the header side power supplies. In the present embodiment, the recessed portion 23b includes a flat inner surface 23g, inclined surfaces 23h provided continuously on both sides of the inner surface 23g in the longitudinal direction X, and consecutively provided on both sides of the inner surface 23g in the vertical direction Z. Together with the inclined surface 23i, it is formed in a substantially quadrangular truncated pyramid shape. An arc-shaped protrusion 33k of a socket-side power supply terminal 33, which will be described later, is fitted into the recess 23b.

Furthermore, the header-side power supply terminal 23 has a tip portion 23c that continues to 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 .

Moreover, the terminal 23 for the header side power supplies is equipped with the to-be-locked part 23d which follows the front-end|tip part 23c. As can be seen by comparing FIGS. 25 and 26, when the header-side power terminal 23 is fitted into the socket-side power terminal 33, the locked portion 23d is deeper than the locking portion 33d as a stepped portion. inserted into Therefore, locked part 23d contacts locking part 33d, when terminal 23 for the header side power supplies is pulled out from terminal 33 for the socket side power supplies. That is, locked part 23d of terminal 23 for the header side power supplies is stopped by locking part 33d of terminal 33 for the socket side power supplies. Therefore, pulling-out from the terminal 33 for socket side power supplies of the terminal 23 for the header side power supplies 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 an external force greater than or equal to a predetermined value 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 are locks capable of releasing mutual locking by applying an external force of a predetermined value or more. make up the mechanism.

23 d of to-be-locked parts may be manufactured by the rolling of the base material which makes the thickness of the terminal 23 for the header side power supplies partially different, but the shaping|molding which bends the base material of the terminal 23 for the header side power supplies to a thickness direction. may be manufactured by

Moreover, the terminal 23 for the header side power supplies is provided with the outer side part 23e arrange|positioned so that the outer surface of the header housing 21 may be followed in the to-be-latched part 23d. The outer portion 23e extends from the locked portion 23d to the plate-like wall portion 21a along the outer surface 21k of the longitudinal wall portion 21e.

Further, the header-side power supply terminal 23 has a root portion (second header-terminal-side fixing portion) 23f that is continuous with the outer portion 23e and protrudes from the side surface of the header housing 21 . The base portion 23 f is a portion fixed to the circuit pattern 41 of the second circuit board 40 with solder 50 . As can be seen from FIG. 25, the upper surface of the base portion 23f extends substantially parallel to the upper surface of the header housing 21 (the outer surface 21j of the plate-like wall portion 21a).

In addition, in this embodiment, as for root part 23f, the width|variety along the longitudinal direction X of the header housing 21 is larger than the width|variety along the longitudinal direction X of the outer side part 23e (other site|part of the terminal 23 for the header side power supplies). It is designed to be narrow. The root portion 23f is connected to the outer portion of the outer portion 23e in the longitudinal direction X (the side away from the adjacent header-side signal terminals 22 in the X direction).

That is, in a state in which the header-side signal terminals 22 and the header-side power supply terminals 23 are 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 arranged. ) 23f, the contact portions (first socket terminal side contact portions) R1 and R2 of the header-side signal terminals 32 and the contact portions (second header terminals Side fixed part) It is made larger than the distance between R3 and R4.

By carrying out like this, the insulation distance of the terminal 23 for the header side power supplies, and the terminal 22 for the header side signals is lengthened, and insulation is ensured.

Moreover, as described above, the header-side signal terminals 22 and the header-side power supply terminals 23 are arranged along the longitudinal direction X of the header housing 21 . And in this embodiment, the width|variety along the longitudinal direction X of the header housing 21 is formed so that the terminal 23 for the header side power supplies may become wider than the width|variety along the longitudinal direction X of the terminal 22 for the header side signals. ing.

That is, he is trying to have the terminal 22 for the header side signals narrower than the terminal 23 for the header side power supplies in the longitudinal direction X of the header housing 21 in this embodiment. In addition, in this embodiment, the width|variety of the longitudinal direction X of the header housing 21 of all the terminals 22 for the header side signals is narrower than the terminal 23 for the header side power supplies.

The socket-side signal terminals 32 and the socket-side power supply terminals 33 are press-fitted into the socket-side signal terminal accommodating portion 31f and the socket-side power supply terminal accommodating portion 31g from the rear surface side of the socket housing 31, respectively.

Next, the configuration of the socket-side signal terminal 32 will be described with reference to FIGS. 17 and 18. FIG.

The socket-side signal terminal 32 is manufactured by metal molding and is a conductor. The socket-side signal terminal 32 has a base portion (first socket-terminal-side fixing portion) 32 a protruding from the side surface of the socket housing 31 . The base portion 32 a is a portion fixed to the circuit pattern 61 of the first circuit board 60 by solder 70 . The bottom surface of the base portion 32a extends along the main surface M of the first circuit board 60 and is positioned in the same plane as the bottom surface of the socket housing 31 (the back surface of the plate-like wall portion 31a).

The socket-side signal terminal 32 has a rising portion 32 b that rises from the base portion 32 a and extends away from the first circuit board 60 . The rising portion 32b bends from the base portion 32a to enter the socket-side signal terminal accommodating recess 31j and extends along the inner surface 31u of the longitudinal wall portion 31h.

The socket-side signal terminal 32 includes an inverted U-shaped portion 32c having one end continuous with the upper end of the rising portion 32b. The inverted U-shaped portion 32c has a shape in which the letter "U" is arranged upside down. Note that the inverted U-shaped portion 32c has a tip end face 32n and inclined faces 32p continuously provided on both sides in the longitudinal direction X of the tip end face 32n. formed in the shape of

The socket-side signal terminal 32 includes a locking portion 32d that continues to the other end of the inverted U-shaped portion 32c. In this embodiment, the locking portion 32d is formed from one end to the other end in the longitudinal direction X of the socket housing 31 in the socket-side signal terminal 32 . That is, a stepped locking portion 32d is formed over the entire width direction of the socket-side signal terminal 32 .

32 d of this latching|locking part functions as a part which suppresses the movement of the to-be-latched part 22e, when the terminal 22 for header side signals is pulled out from the terminal 32 for socket side signals, as mentioned above. That is, locking part 32d of terminal 32 for the socket side signals contacts locked part 22e of terminal 22 for the header side signals, and can lock locked part 22e. The locking portion 32d of the socket-side signal terminal 32 and the locked portion 22e of the header-side signal terminal 22 constitute a locking mechanism that can be unlocked by applying an external force of a predetermined value or more. ing.

Although 32 d of latching|locking parts may be manufactured by the rolling of the base material which makes the thickness of the terminal 32 for socket side signals partially different, by the shaping|molding which bends the base material of the terminal 32 for socket side signals in a thickness direction, may be manufactured.

Further, the socket-side signal terminal 32 has a falling portion 32e that is continuous with the locking portion 32d and extends substantially parallel to the rising portion 32b.

And the terminal 32 for socket side signals is equipped with the inclination part 32f which follows the lower end of the falling part 32e. In addition, you may make it the terminal 32 for socket side signals change to the inclination part 32f, and be equipped with the 1st circular part 32f.

As shown in FIGS. 23 and 24, the socket-side signal terminal 32 has a facing portion 32z continuous with the inclined portion 32f. The facing portion 32z includes a flat portion 32g, a first slanted portion 32h, a second arcuate portion 32i, a second slanted portion 32j, an arcuate protrusion 32k, and a tip portion 32m, which will be described below. Specifically, the facing portion 32z is as follows.

The facing portion 32z has a flat portion 32g that continues to the lower end of the inclined portion 32f. 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 need not be parallel to the main surface M. The flat portion 32g is provided to increase the spring length of the spring portion, which will be described later.

As shown in FIG. 23, the facing portion 32z has a first slanted portion 32h that is continuous with the flat portion 32g and extends obliquely with respect to the main surface M of the first circuit board 60. As shown in FIG. The first slanted portion 32 h extends away from the falling portion 32 e as it separates from the first circuit board 60 . The first oblique portion 32h is continuous with the second arcuate portion 32i. The second arcuate portion 32i is a curved portion protruding away from the falling portion 32e. The second arcuate portion 32i is continuous with a second oblique portion 32j extending obliquely with respect to the main surface M of the first circuit board 60 . The second slanted portion 32j extends closer to 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. 23, the opposing portion 32z has an arcuate protrusion 32k that is continuous with the upper end of the second slanted portion 32j. The arcuate protrusion 32k has a tip surface 32r and inclined surfaces 32s continuously provided on both sides in the longitudinal direction X of the tip surface 32r, and is formed in a projecting shape protruding in a substantially trapezoidal shape when viewed in a horizontal cross section. It is

As shown in FIG. 23, the arcuate protrusion 32k fits into the recess 22c of the header-side signal terminal 22. As shown in FIG. The other end of the arcuate protrusion 32k is continuous with the tip 32m. The tip portion 32m extends substantially parallel to the second oblique portion 32j. As can be seen from FIGS. 23 and 24, the facing portion 32z (32g, 32h, 32i, 32j, 32k, 32m) continues to 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 together, the header-side signal terminal 22 is inserted between the inverted U-shaped portion 32c and the arcuate protrusion 32k as shown in FIG. be done. At this time, the falling portion 32e, the inclined portion 32f, the flat portion 32g, the first slanted portion 32h, the arcuate portion 32i, the second slanted portion 32j, the arcuate protrusion 32k, and the tip portion 32m are integrated. function as a spring. Spring part (32e, 32f, 32g, 32h, 32i, 32j, 32k, 32m) will elastically deform, if the convex part of the terminal 22 for the header side signals is inserted in the recessed part of the terminal 32 for the socket side signals. As a result, the distance between the two portions of the falling portion 32e and the inverted U-shaped portion 32c and the arcuate protrusion 32k is increased. At this time, locked part 22e of terminal 22 for the header side signals is inserted below rather than locking part 32d of terminal 32 for the socket side signals. Thereby, circular projection part 32k of terminal 32 for the socket side signals fits into crevice 22c of terminal 22 for the header side signals.

In a state where the header-side signal terminals 22 are fitted to the socket-side signal terminals 32, a restoring force is generated in the elastically deformed spring portion. Due to this restoring force, the arc-shaped protrusion 32k presses the header-side signal terminal 22 against each of the falling portion 32e and the inverted U-shaped portion 32c. Thereby, terminal 22 for the header side signals is pinched by terminal 32 for the socket side signals. At this time, the header-side signal terminal 22 contacts each of the inverted U-shaped portion 32c, the falling portion 32e, and the arcuate projection portion 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) R1 of the socket side signal terminal 32 and the contact portion (first header terminal side contact portion) R1 of the header side signal terminal 22 come into contact with each other. .

Moreover, the recessed part 22c of the terminal 22 for the header side signals contacts the circular projection part 32k of the terminal 32 for the socket side signals. 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 terminals 22 and the socket-side signal terminals 32 are in contact with each other at a plurality of contact points (two contact portions, the contact portion R1 and the contact portion R2) spaced apart in the width direction Y. Therefore, the reliability of electrical connection between the header-side signal terminals 22 and the socket-side signal terminals 32 is high.

Furthermore, in the present embodiment, the contact portion of the header-side signal terminal 22, which is one of the contact portion R2 of the socket-side signal terminal 32 and the contact portion R2 of the header-side signal terminal 22, which is in contact with each other A recess 22c is formed in R2. And he is trying for the contact part R2 of the terminal 32 for the socket side signals which is the other contact part to contact with the longitudinal direction X both ends of the socket housing 31 in the recessed part 22c.

Specifically, when the arc-shaped projection 32k of the socket-side signal terminal 32 is fitted into the recess 22c, the boundary between the tip surface 32r of the arc-shaped projection 32k and the inclined surface 32s is formed on the inclined surface 22h. in contact. Thus, he is trying for contact part R2 of terminal 32 for the socket side signals to contact contact part R2 of terminal 22 for the header side signals at two points in this embodiment.

Due to the elastic deformation of the spring portion, the boundary portion between the flat portion 32g and the first oblique portion 32h contacts the first circuit board 60 at the contact portion R5 in addition to the contact portions R1 and R2. In some cases.

Thus, the terminal 22 for the header side signals and the terminal 32 for the socket side signals of this embodiment are in contact with the some contact point spaced apart in the width direction Y. As shown in FIG. 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 point of contact between the inner surface of the header-side signal terminal and the opposing portion of the socket-side signal terminal. good too.

The spring portions (32e, 32f, 32g, 32h, 32i, 32j, 32k, 32m) are composed of U-shaped portions (32e, 32f, 32g, 32h, 32i, 32j) and the U-shaped portions (32e, 32f, 32g, 32h, 32i, 32j) and free end portions (32k, 32m) connected to one end (32j side). A contact portion R2 of the socket-side signal terminal 32 is provided on the arc-shaped projection portion 32k of the free end portions (32k, 32m).

Thus, the socket-side signal terminal 32 has U-shaped portions (32e, 32f, 32g, 32h, 32i, 32j), and the U-shaped portions (32e, 32f, 32g, 32h, 32i) , 32j) are connected to free end portions (32k, 32m) provided with contact portions R2.

Such a socket-side signal terminal 32 can be formed by curving a strip-shaped metal material having a predetermined thickness.

Further, when the socket 30 is assembled, the socket-side signal terminal 32 is inserted (press-fitted) into the socket-side signal terminal accommodating portion 31f from the rear surface side (lower side in FIG. 14) of the socket housing 31 so that the socket housing 31 is installed.

In addition, you may make it mount|wear the socket housing 31 with the terminal 32 for the socket side signals by insert-molding the terminal 32 for the socket side signals in the socket housing 31, etc. FIG.

In addition, the inverted U-shaped portion 33c has a tip end surface 33r and inclined surfaces 33s continuously provided on both sides in the longitudinal direction X of the tip end surface 33r. formed in the shape of

The socket-side power supply terminal 33 has a locking portion 33d that continues to the other end of the inverted U-shaped portion 33c. 33 d of this latching|locking parts function as a part which suppresses the movement of 23 d of to-be-latched parts, when the terminal 23 for header side power supplies is pulled out from the terminal 33 for socket side power supplies, as mentioned above. That is, locking part 33d of terminal 33 for the socket side power supplies contacts locked part 23d of terminal 23 for the header side power supplies, and can lock locked part 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 lock mechanism capable of releasing the locking by applying an external force of a predetermined value or more. ing.

Although 33 d of latching|locking parts may be manufactured by the rolling of the base material which makes the thickness of the terminal 33 for socket side power supplies partially different, by the shaping|molding which bends the base material of the terminal 33 for socket side power supplies to a thickness direction, may be manufactured.

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

And the terminal 33 for socket side power supplies is equipped with the inclination part 33f which follows the lower end of the falling part 33e. In addition, you may make it the terminal 33 for socket side power supplies change to the inclination part 33f, and be provided with the 1st circular part 33f.

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

The facing portion 33z has a flat portion 33g that continues to 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 away from falling portion 33e. However, the flat portion 33g need not be parallel to the main surface M. The flat portion 33g is provided to increase the spring length of the spring portion, which will be described later.

As shown in FIG. 25, the opposing portion 33z has a first slanted portion 33h that is continuous with the flat portion 33g and extends obliquely with respect to the main surface M of the first circuit board 60. As shown in FIG. The first slanted portion 33 h extends away from the falling portion 33 e as it separates from the first circuit board 60 . The first oblique portion 33h is continuous with the second arcuate portion 33i. The second arcuate portion 33i is a curved portion protruding away from the falling portion 33e. The second arcuate portion 33i is continuous with a second oblique portion 33j extending obliquely with respect to the main surface M of the first circuit board 60 . The second slanted portion 33j extends closer to the falling portion 33e as it separates from the first circuit board 60. As shown in FIG. Therefore, the second diagonal portion 33j is positioned above the first diagonal portion 33h.

As shown in FIG. 35, the opposing portion 33z has an arcuate protrusion 33k that is continuous with the upper end of the second slanted portion 33j. The arcuate protrusion 33k has a tip end face 33v and inclined faces 33w continuously provided on both sides in the longitudinal direction X of the tip end face 33v, and is formed in a projecting shape protruding in a substantially trapezoidal shape in a horizontal cross-sectional view. It is

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

Thus, in this 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 have substantially the same shape (see FIGS. 18A and 20A). ).

In this embodiment, when the header 20 and the socket 30 are fitted together, as shown in FIG. 33c and the arcuate protrusion 33k. At this time, the falling portion 33e, the inclined portion 33f, the flat portion 33g, the first slanted portion 33h, the arc-shaped portion 33i, the second slanted portion 33j, the arc-shaped protrusion 33k, and the tip portion 33m are integrated. function as a spring. Spring part (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) will elastically deform, if the convex part of terminal 23 for the header side power supplies is inserted in the crevice of terminal 33 for the socket side power supplies.

In this embodiment, the width (width along the longitudinal direction X) from the inclined portion 33f to the distal end portion 33m is the rising portion 33b, the inverted U-shaped portion 33c, the engaging portion 33d, and the falling portion 33e. (the width along the longitudinal direction X). Therefore, the spring portions (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) are particularly prone to elastic deformation in the portion from the inclined portion 33f to the tip portion 33m.

Then, 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 arcuate projection portion 33k the distance between them increases. At this time, locked part 23d of terminal 23 for the header side power supplies is inserted below rather than locking part 33d of terminal 33 for the socket side power supplies. Thereby, circular projection part 33k of terminal 33 for the socket side power supplies fits into crevice 23b of terminal 23 for the header side power supplies.

In the state where the terminal 23 for the header side power supplies fitted to the terminal 33 for the socket side power supplies, restoring force arises in the elastically deformed spring part. 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. Thereby, the terminal 23 for the header side power supplies is clamped by the terminal 33 for the socket side power supplies. At this time, the terminal 23 for the header side power supplies contacts each of the inverted U-shaped part 33c of the terminal 33 for the socket side power supplies, the falling part 33e, and the circular protrusion part 33k.

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

Moreover, the recessed part 23b of the terminal 23 for the header side power supplies contacts the circular projection part 33k of the terminal 33 for the socket side power supplies. That is, the contact portion (second socket terminal side contact portion) R4 of the socket side power supply terminal 33 and the contact portion (second header terminal side contact portion) R4 of the header side power supply terminal 23 come into contact with each other. .

Thus, the terminal 23 for the header side power supplies and the terminal 33 for the socket side power supplies contact with the several contact (two contact parts of contact part R3 and contact part R4) spaced apart in the width direction Y. FIG. Therefore, the reliability of 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 the two positions of the socket-side power supply terminal 33 are arranged so that the contact portion R3 is closer to the root portion (second socket terminal side fixing portion) 33a than the contact portion R4. positioned.

In the present embodiment, the cross-sectional area of the contact portion R3 located closer to the base portion (second socket terminal side fixing portion) 33a of the contact portion R3 and the contact portion R4 is the contact portion located on the other side. It is made 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 (board thickness) of the contact portions R3 and R4 of the socket-side power supply terminal 33 .

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

Further, in the present embodiment, the root portion 33a is formed such that the width along the longitudinal direction X of the socket housing 31 is narrower than the width along the longitudinal direction X of the rising portion 33b. The root portion 33a is connected to the outer portion of the rising portion 33b in the longitudinal direction X (the side away from the adjacent socket-side signal terminals 32 in the X direction).

Further, the root portion 33a is attached to the contact portion R3 and the contact portion R4 in a state in which the socket-side signal terminal 32 and the socket-side power supply terminal 33 are arranged in the socket housing 31. part) 32a is offset away from 32a.

That is, the root portion (second socket terminal side fixing portion) 33a is connected to the rising portion 33b in a state of protruding outward in the longitudinal direction X from the rising portion 33b.

By doing so, in a state in which the socket-side signal terminal 32 and the socket-side power supply terminal 33 are arranged in the socket housing 31, the root portion (first socket terminal side fixing portion) 32a and the root portion (second socket terminal side fixing portion) 33a, the distance between the contact portions (first socket terminal side contact portions) R1 and R2 of the socket side signal terminal 32 and the contact portion of the socket side power supply terminal 33 (second socket Terminal side contact portion) is made larger than the distance between R3 and R4.

By doing so, the insulation distance between the socket-side power supply terminal (second socket terminal) 33 and the socket-side signal terminal (first socket terminal) 32 (the base portion 33a and the base portion 32a adjacent to each other in the X direction distance) can be increased.

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 protrude outward in the longitudinal direction X beyond the rising portion 33b. It is also possible to lengthen the insulation distance.

Moreover, as above-mentioned, the side surface shape of the terminal 32 for the socket side signals, and the side surface shape of the terminal 33 for the socket side power supplies are carrying out substantially the same shape.

Furthermore, the socket-side signal terminals 32 and the socket-side power supply terminals 33 are arranged in a row along the longitudinal direction X of the socket housing 31 .

And the terminal 33 for socket side power supplies is formed so that the width|variety along the longitudinal direction X of the socket housing 31 may become wider than the width|variety along the longitudinal direction X of the terminal 32 for socket side signals.

That is, he is trying to have terminal 32 for socket side signals whose width of longitudinal direction X of socket housing 31 is narrower than terminal 33 for socket side power supplies in this embodiment. In addition, in this embodiment, the width|variety of the longitudinal direction X of the socket housing 31 of all the terminals 32 for the socket side signals is narrower than the terminal 33 for the socket side power supplies.

Furthermore, he is trying for the thickness (board thickness) of the terminal 33 for socket side power supplies to become thinner than the thickness (board thickness) of the terminal 32 for the socket side signals in this embodiment.

Moreover, 33 d of latching|locking parts are formed from the one end of the longitudinal direction X of the socket housing 31 in the terminal 33 for socket side power supplies to the other end. That is, the stepped locking portion 33d is formed over the entire width direction of the wide socket-side power supply terminal 33 . By carrying out like this, the locking force by to-be-latched part 23d of the terminal 23 for the header side power supplies, and the latching|locking part 33d of the terminal 33 for the socket side power supplies can be improved. Further, even when the header 20 and the socket 30 are repeatedly inserted and removed, the locking portion 33d is less likely to be worn, so that it is possible to extend the life of the product.

Furthermore, in the present embodiment, the spring portions (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) include the U-shaped portions (33e, 33f, 33g, 33h, 33i, 33j) and the U-shaped Free end portions (33k, 33m) connected to one end (33j side) of the shaped portions (33e, 33f, 33g, 33h, 33i, 33j). A contact portion R4 of the socket-side signal terminal 33 is provided on the arcuate projection portion 33k of the free end portions (33k, 33m).

Thus, the socket-side power supply terminal 33 has U-shaped portions (33e, 33f, 33g, 33h, 33i, 33j), and the U-shaped portions (33e, 33f, 33g, 33h, 33i) , 33j) are connected to free end portions (33k, 33m) provided with contact portions R4.

A recess 23b is formed in R4. And he is trying for the contact part R4 of the terminal 33 for socket side power supplies which is the other contact part to contact with the longitudinal direction X both ends of the socket housing 31 in the recessed part 23b.

Specifically, when the arcuate protrusion 33k of the socket-side power supply terminal 33 is fitted into the recess 23b, the boundary between the tip end surface 33v of the arcuate protrusion 33k and the inclined surface 33w is formed on the inclined surface 23h. in contact. Thus, he is trying for contact part R4 of terminal 33 for the socket side power supplies to contact contact part R4 of terminal 23 for the header side power supplies at two points in this embodiment.

Due to the elastic deformation of the spring portion, the boundary portion between the flat portion 33g and the first oblique portion 33h contacts the first circuit board 60 at the contact portion R5 in addition to the contact portions R3 and R4. In some cases.

Thus, the terminal 23 for the header side power supplies and the terminal 33 for the socket side power supplies of this embodiment are in contact with the some contact point spaced apart in the width direction Y.
