　次に、図４から図６を参照しながら、ヘッダハウジング２１の構成を説明する。 Next, the configuration of the header housing 21 will be described with reference to FIGS.
　ヘッダハウジング２１は、板状壁部２１ａと、その周縁部に沿って略矩形環状に連続的に形成される周壁部２１ｂとで一方側（図５の下側）が開口した略箱状に形成されている。 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-like wall portion 21a and a peripheral wall portion 21b continuously formed in a substantially rectangular ring shape along the peripheral edge portion.

Further, a tapered portion 21d is formed at the lower end on the outer peripheral side of the peripheral wall portion 21b. The tapered portion 21d is inclined so as to be located upward (toward the plate-like wall portion 21a) as it goes outward.
　なお、隣り合うヘッダ側信号用端子２２の間や、ヘッダ側信号用端子群Ｇ３とヘッダ側電源用端子２３との間の周壁部２１ｂは、Ｒ状（逆Ｕ字状）に湾曲形成されている。 The peripheral wall 21b between the adjacent header-side signal terminals 22 or between the header-side signal terminal group G3 and the header-side power supply terminal 23 is curved and formed in an R shape (inverted U shape). Yes.
　また、本実施形態では、周壁部２１ｂは、幅方向（短手方向）Ｙに対向する一対の長手方向壁部２１ｅと、長手方向Ｘに対向する一対の短手方向壁部２１ｆと、を備えている。 In the present embodiment, the peripheral wall portion 21b includes a pair of longitudinal wall portions 21e facing the width direction (short direction) Y and a pair of short direction wall portions 21f facing the longitudinal direction X. ing.
　そして、短手方向壁部２１ｆの幅方向Ｙの長さが、対向する２つの長手方向壁部２１ｅの距離（一方の長手方向壁部２１ｅの外面２１ｋから他方の長手方向壁部２１ｅの外面２１ｋまでの距離）とほぼ同一となるように形成されている。さらに、長手方向壁部２１ｅの長手方向Ｘの長さが、対向する２つの短手方向壁部２１ｆの距離（一方の短手方向壁部２１ｆの外面２１ｍから他方の短手方向壁部２１ｆの外面２１ｍまでの距離）とほぼ同一となるように形成されている。 The length in the width direction Y of the short-side wall portion 21f is the distance between 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. It is formed so as to be almost the same as the distance up to. Further, the length in the longitudinal direction X of the longitudinal wall portion 21e is the distance between two opposing short-side wall portions 21f (from the outer surface 21m of one short-side wall portion 21f to the other short-side wall portion 21f. The distance to the outer surface 21 m is substantially the same.
　このように、本実施形態では、ヘッダハウジング２１は、全体的に平面視略矩形状に形成されている。したがって、長手方向壁部２１ｅの外面２１ｋおよび短手方向壁部２１ｆの外面２１ｍが周壁部２１ｂの外面２１ｈとなっており、長手方向壁部２１ｅの内面２１ｎおよび短手方向壁部２１ｆの内面２１ｐが周壁部２１ｂの内面２１ｉとなっている。 Thus, in this embodiment, the header housing 21 is formed in a substantially rectangular shape in plan view as a whole.

Is the inner surface 21i of the peripheral wall 21b.
　次に、図７および図８を参照しながら、ヘッダ側信号用端子２２の構成を説明する。 Next, the configuration of the header-side signal terminal 22 will be described with reference to FIGS.
　ヘッダ側信号用端子２２は、金属成形により製造されており、導電体である。そして、ヘッダ側信号用端子２２は、ヘッダハウジング２１の側面から突出する付け根部（第１のヘッダ端子側固定部）２２ａを備えている。付け根部２２ａは、第２の回路基板４０の回路パターンに半田によって固定される部位である。また、付け根部２２ａの上面は、図２３から分かるように、ヘッダハウジング２１の上面（板状壁部２１ａの外表面２１ｊ）に対して略平行に延びている。 The header-side signal terminal 22 is manufactured by metal forming and is a conductor. The header-side signal terminal 22 includes a base portion (first header terminal-side fixing portion) 22 a that protrudes from the side surface of the header housing 21. The base portion 22a is a portion that is fixed to the circuit pattern of the second circuit board 40 with solder. Further, 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).
　また、ヘッダ側信号用端子２２は、付け根部２２ａに連続する内側部２２ｂを有する。内側部２２ｂは、ヘッダハウジング２１の板状壁部２１ａと長手方向壁部２１ｅとの接合部を曲がりながら貫通し、長手方向壁部２１ｅの内面２１ｎに沿って長手方向壁部２１ｅの先端部まで延びている。 Further, the header-side signal terminal 22 has an inner portion 22b continuous with the base portion 22a. The inner portion 22b passes through the joint portion between the plate-like wall portion 21a and the longitudinal wall portion 21e of the header housing 21 while bending, and extends to the distal end portion of the longitudinal wall portion 21e along the inner surface 21n of the longitudinal wall portion 21e. It extends.
　そして、ヘッダ側信号用端子２２の内側部２２ｂの内側表面上には、凹部２２ｃが形成されている。本実施形態では、凹部２２ｃは、長手方向Ｘの両側に連設された傾斜面２２ｈと、上下方向Ｚの両側に連設された傾斜面２２ｉとで、略三角柱状に形成されている。凹部２２ｃには、後述するソケット側信号用端子３２の円弧状突起部３２ｋが嵌まり込む。 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 recess 22c is formed in a substantially triangular prism shape by an inclined surface 22h provided continuously on both sides in the longitudinal direction X and an inclined surface 22i provided continuously on both sides in the vertical direction Z. An arcuate protrusion 32k of a socket-side signal terminal 32 to be described later is fitted into the recess 22c.
　さらに、ヘッダ側信号用端子２２は、内側部２２ｂの一方端に連続する先端部２２ｄを備えている。先端部２２ｄは、ヘッダハウジング２１の長手方向壁部２１ｅの先端の形状に沿って曲がっている。 Furthermore, the header-side signal terminal 22 includes a tip portion 22d continuous with one end of the inner portion 22b. The distal end portion 22d is bent along the shape of the distal end of the longitudinal wall portion 21e of the header housing 21.
　ヘッダ側信号用端子２２は、先端部２２ｄに連続する被係止部２２ｅを備えている。本実施形態では、被係止部２２ｅは、ヘッダ側信号用端子２２におけるヘッダハウジング２１の長手方向Ｘの一端から他端にかけて形成されている。すなわち、ヘッダ側信号用端子２２の幅方向全体に亘って、段差状の被係止部２２ｅが形成されている。 The header-side signal terminal 22 includes a locked portion 22e continuous to 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 22 e is formed over the entire width direction of the header-side signal terminal 22.
　被係止部２２ｅは、図２３および図２４を対比すれば分かるように、ヘッダ側信号用端子２２がソケット側信号用端子３２に嵌め込まれるときに、段差部としての係止部３２ｄよりも奥へ挿入される。そのため、被係止部２２ｅは、ヘッダ側信号用端子２２がソケット側信号用端子３２から引き抜かれるときに、係止部３２ｄに当接する。つまり、ヘッダ側信号用端子２２の被係止部２２ｅは、ソケット側信号用端子３２の係止部３２ｄによって係止される。したがって、ヘッダ側信号用端子２２のソケット側信号用端子３２からの引き抜けが抑制されている。つまり、ヘッダ側信号用端子２２は、所定値よりも小さな外力をかけただけでは、ソケット側信号用端子３２から引き抜くことができない。一方、ヘッダ側信号用端子２２は、所定値以上の大きな外力をかけると、ソケット側信号用端子３２から引き抜かれ得る。つまり、ヘッダ側信号用端子２２の被係止部２２ｅおよびソケット側信号用端子３２の係止部３２ｄは、所定値以上の外力を加えることにより、互いの係止を解除することが可能なロック機構を構成している。 As can be seen by comparing FIG. 23 and FIG. 24, the locked portion 22 e is deeper than the locking portion 32 d as the step portion when the header-side signal terminal 22 is fitted into the socket-side signal terminal 32. Is inserted. 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 22 e of the header side signal terminal 22 is locked by the locking portion 32 d of the socket side signal terminal 32. Accordingly, the 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. 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 can be unlocked by applying an external force of a predetermined value or more. The mechanism is configured.
　被係止部２２ｅは、ヘッダ側信号用端子２２の厚さを部分的に異ならせる母材の圧延により製造されてもよいが、ヘッダ側信号用端子２２の母材を厚さ方向に曲げる成形により製造されてもよい。 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 is formed by bending the base material of the header-side signal terminal 22 in the thickness direction. May be manufactured.
　さらに、ヘッダ側信号用端子２２は、被係止部２２ｅを介して、先端部２２ｄに連続し、長手方向壁部２１ｅの外面２１ｋに沿って延びる外側部２２ｆを備えている。本実施形態では、長手方向壁部２１ｅ（周壁部２１ｂ）の外周に突設された突出壁部２１ｇによって、ヘッダ側信号用端子２２の外側部２２ｆの先端の位置決めがなされている。 Further, the header-side signal terminal 22 includes an outer portion 22f that is continuous with the distal end portion 22d through the locked portion 22e and extends along the outer surface 21k of the longitudinal wall portion 21e. In the present embodiment, the distal 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 (the peripheral wall portion 21b).
　このようなヘッダ側信号用端子２２は、所定厚さを持った帯状の金属材を湾曲成形することにより形成することができる。 Such a header-side signal terminal 22 can be formed by bending a band-shaped metal material having a predetermined thickness.
　また、本実施形態では、ヘッダ側信号用端子２２は、インサート成形によってヘッダハウジング２１に配設されるようにしている。なお、ヘッダ側信号用端子２２をヘッダハウジング２１に圧入することで、ヘッダ側信号用端子２２をヘッダハウジング２１に配設させてもよい。 In this 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.
　次に、図９および図１０を参照しながら、ヘッダ側電源用端子２３およびヘッダ側保持金具２４の構成を説明する。 Next, the configuration of the header-side power supply terminal 23 and the header-side holding bracket 24 will be described with reference to FIGS. 9 and 10.
　ヘッダ側電源用端子２３は、金属成形により製造されており、導電体である。そして、このヘッダ側電源用端子２３は、ヘッダハウジング２１の内面に沿うように配置される内側部２３ａを備えている。内側部２３ａは、ヘッダハウジング２１の板状壁部２１ａと長手方向壁部２１ｅとの接合部から長手方向壁部２１ｅの内面２１ｎに沿って長手方向壁部２１ｅの先端部まで延びている。 The header-side power supply terminal 23 is manufactured by metal forming and is a conductor. The header-side power supply terminal 23 includes an inner portion 23 a disposed along the inner surface of the header housing 21. The inner portion 23a extends from the joint portion between the plate-like wall portion 21a of the header housing 21 and the longitudinal wall portion 21e to the distal end portion of the longitudinal wall portion 21e along the inner surface 21n of the longitudinal wall portion 21e.
　そして、ヘッダ側電源用端子２３の内側部２３ａの内側表面上には、凹部２３ｂが形成されている。本実施形態では、凹部２３ｂは、平坦状の奥面２３ｇと、奥面２３ｇの長手方向Ｘの両側に連設された傾斜面２３ｈと、奥面２３ｇの上下方向Ｚの両側に連設された傾斜面２３ｉとで、略四角錐台状に形成されている。凹部２３ｂには、後述するソケット側電源用端子３３の円弧状突起部３３ｋが嵌まり込む。 Further, a recess 23b is formed on the inner surface of the inner portion 23a of the header-side power supply terminal 23. In the present embodiment, the recess 23b is connected to both the flat back surface 23g, the inclined surfaces 23h connected to both sides in the longitudinal direction X of the back surface 23g, and both sides of the back surface 23g in the vertical direction Z. The inclined surface 23i is formed in a substantially quadrangular 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.
　さらに、ヘッダ側電源用端子２３は、内側部２３ａの一方端に連続する先端部２３ｃを備えている。先端部２３ｃは、ヘッダハウジング２１の長手方向壁部２１ｅの先端の形状に沿って曲がっている。 Furthermore, the header-side power supply terminal 23 includes a distal end portion 23c that is continuous with one end of the inner side portion 23a. The distal end portion 23 c is bent along the shape of the distal end of the longitudinal wall portion 21 e of the header housing 21.
　また、ヘッダ側電源用端子２３は、先端部２３ｃに連続する被係止部２３ｄを備えている。図２５および図２６を対比すれば分かるように、被係止部２３ｄは、ヘッダ側電源用端子２３がソケット側電源用端子３３に嵌め込まれるときに、段差部としての係止部３３ｄよりも奥へ挿入される。そのため、被係止部２３ｄは、ヘッダ側電源用端子２３がソケット側電源用端子３３から引き抜かれるときに、係止部３３ｄに当接する。つまり、ヘッダ側電源用端子２３の被係止部２３ｄは、ソケット側電源用端子３３の係止部３３ｄによって係止される。したがって、ヘッダ側電源用端子２３のソケット側電源用端子３３からの引き抜けが抑制されている。つまり、ヘッダ側電源用端子２３は、所定値よりも小さな外力をかけただけでは、ソケット側電源用端子３３から引き抜くことができない。一方、ヘッダ側電源用端子２３は、所定値以上の大きな外力をかけると、ソケット側電源用端子３３から引き抜かれ得る。つまり、ヘッダ側電源用端子２３の被係止部２３ｄおよびソケット側電源用端子３３の係止部３３ｄは、所定値以上の外力を加えることにより、互いの係止を解除することが可能なロック機構を構成している。 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 23 d is deeper than the locking portion 33 d as a step portion when the header-side power supply terminal 23 is fitted into the socket-side power supply terminal 33. Is inserted. Therefore, the locked portion 23d comes into contact with 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 23 d of the header-side power supply terminal 23 is locked by the locking portion 33 d of the socket-side power supply terminal 33. Accordingly, pulling out 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 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 by applying an external force of a predetermined value or more. The mechanism is configured.
　被係止部２３ｄは、ヘッダ側電源用端子２３の厚さを部分的に異ならせる母材の圧延により製造されてもよいが、ヘッダ側電源用端子２３の母材を厚さ方向に曲げる成形により製造されてもよい。 The locked portion 23d may be manufactured by rolling a base material that partially varies 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.
　また、ヘッダ側電源用端子２３は、被係止部２３ｄに連続し、ヘッダハウジング２１の外面に沿うように配置される外側部２３ｅを備えている。外側部２３ｅは、被係止部２３ｄから長手方向壁部２１ｅの外面２１ｋに沿って板状壁部２１ａまで延びている。 The header-side power supply terminal 23 includes an outer portion 23e that 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-like wall portion 21a along the outer surface 21k of the longitudinal wall portion 21e.
　また、ヘッダ側電源用端子２３は、外側部２３ｅに連続し、ヘッダハウジング２１の側面から突出する付け根部（第２のヘッダ端子側固定部）２３ｆを備えている。付け根部２３ｆは、第２の回路基板４０の回路パターンに半田によって固定される部位である。また、付け根部２３ｆの上面は、図２５から分かるように、ヘッダハウジング２１の上面（板状壁部２１ａの外表面２１ｊ）に対して略平行に延びている。 The header-side power supply terminal 23 includes a base 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 23f is a portion that is fixed to the circuit pattern of the second circuit board 40 with solder. Further, 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).
　なお、本実施形態では、付け根部２３ｆは、ヘッダハウジング２１の長手方向Ｘに沿った幅が、外側部２３ｅ（ヘッダ側電源用端子２３の他の部位）の長手方向Ｘに沿った幅よりも狭くなるように形成されている。そして、付け根部２３ｆは、外側部２３ｅの長手方向Ｘの外側の部分（Ｘ方向で隣り合うヘッダ側信号用端子２２から離れた側）に連設されている。 In the present embodiment, the width of the base portion 23f along the longitudinal direction X of the header housing 21 is greater than the width along the longitudinal direction X of the outer portion 23e (the other part of the header-side power supply terminal 23). It is formed to be narrow. The base 23f is connected to the outer portion of the outer portion 23e in the longitudinal direction X (the side away from the header-side signal terminal 22 adjacent in the X direction).
　すなわち、ヘッダ側信号用端子２２およびヘッダ側電源用端子２３をヘッダハウジング２１に配置した状態で、付け根部（第１のヘッダ端子側固定部）２２ａと付け根部（第２のヘッダ端子側固定部）２３ｆとの間の距離が、後述するヘッダ側信号用端子２２の接点部（第１のソケット端子側接点部）Ｒ１，Ｒ２と、ヘッダ側電源用端子２３の接点部（第２のヘッダ端子側固定部）Ｒ３，Ｒ４との間の距離よりも大きくなるようにしている。 That is, in a state where the header-side signal terminal 22 and the header-side power supply terminal 23 are arranged in the header housing 21, the base portion (first header terminal side fixing portion) 22 a and the base portion (second header terminal side fixing portion) ) 23f is a contact portion (first socket terminal side contact portion) R1, R2 of the header side signal terminal 22 described later and a contact portion (second header terminal) of the header side power supply terminal 23. Side fixing portions) are set to be larger than the distance between R3 and R4.
　こうすることで、ヘッダ側電源用端子２３とヘッダ側信号用端子２２との絶縁距離を長くして、絶縁性を確保している。 By doing so, the insulation distance between the header-side power supply terminal 23 and the header-side signal terminal 22 is increased to ensure insulation.
　また、上述したように、ヘッダ側信号用端子２２およびヘッダ側電源用端子２３は、ヘッダハウジング２１の長手方向Ｘに沿って配設されている。そして、本実施形態では、ヘッダ側電源用端子２３は、ヘッダハウジング２１の長手方向Ｘに沿った幅が、ヘッダ側信号用端子２２の長手方向Ｘに沿った幅よりも広くなるように形成されている。 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 along the longitudinal direction X of the header housing 21 is wider than the width along the longitudinal direction X of the header-side signal terminal 22. ing.
　すなわち、本実施形態では、ヘッダ側電源用端子２３よりもヘッダハウジング２１の長手方向Ｘの幅が狭いヘッダ側信号用端子２２を有するようにしている。なお、本実施形態では、全てのヘッダ側信号用端子２２が、ヘッダ側電源用端子２３よりもヘッダハウジング２１の長手方向Ｘの幅が狭くなっている。 That is, in this embodiment, the header-side signal terminal 22 is narrower in the longitudinal direction X of the header housing 21 than the header-side power supply terminal 23. In the present embodiment, all header-side signal terminals 22 are narrower in the longitudinal direction X of the header housing 21 than the header-side power terminals 23.
　さらに、本実施形態では、被係止部２３ｄが、ヘッダ側電源用端子２３におけるヘッダハウジング２１の長手方向Ｘの一端から他端にかけて形成されている。すなわち、幅広のヘッダ側電源用端子２３の幅方向全体に亘って、段差状の被係止部２３ｄを形成している。こうすることで、ヘッダ側電源用端子２３の被係止部２３ｄおよびソケット側電源用端子３３の係止部３３ｄによるロック力を向上させることができる。また、ヘッダ２０およびソケット３０の挿抜を繰り返した際にも、被係止部２３ｄが摩耗しにくくなるため、製品の長寿命化を図ることが可能となる。 Furthermore, in this embodiment, the locked portion 23d is formed from one end to the other end of the header housing 21 in the longitudinal direction X of the header housing 21. That is, a stepped locked portion 23d is formed over the entire width direction of the wide header-side power supply terminal 23. By doing so, the locking force by 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 improved. In addition, when the insertion and removal of the header 20 and the socket 30 are repeated, the locked portion 23d is less likely to be worn, so that the product life can be extended.
　また、本実施形態では、ヘッダ側電源用端子２３は、インサート成形によってヘッダハウジング２１に配設されるようにしている。なお、ヘッダ側電源用端子２３をヘッダハウジング２１に圧入することで、ヘッダ側電源用端子２３をヘッダハウジング２１に配設させてもよい。 In this embodiment, the header-side power supply terminal 23 is arranged in the header housing 21 by insert molding. The header-side power terminal 23 may be disposed in the header housing 21 by press-fitting the header-side power terminal 23 into the header housing 21.
　そして、ヘッダ側電源用端子２３には、連結部２５を介してヘッダ側保持金具２４が固定されている。 And the header side holding | maintenance metal fitting 24 is being fixed to the header side power supply terminal 23 via the connection part 25. As shown in FIG.
　ヘッダ側保持金具２４は、ヘッダ側信号用端子２２やヘッダ側電源用端子２３と同様に金属成形により製造されており、導電体である。 The header side holding metal fitting 24 is manufactured by metal forming similarly to the header side signal terminal 22 and the header side power supply terminal 23, and is a conductor.
　そして、ヘッダ側電源用端子２３とヘッダ側保持金具２４とを一体化させた部材は、所定厚さを持った金属板を湾曲成形することにより形成することができる。 The member in which the header side power supply terminal 23 and the header side holding metal fitting 24 are integrated can be formed by bending a metal plate having a predetermined thickness.
　ヘッダ側保持金具２４は、短手方向壁部２１ｆの先端（下端）のほぼ全体を覆うように配置される略矩形板状の下壁部２４ａを備えている。 The header side holding metal fitting 24 is provided with a substantially rectangular plate-like lower wall portion 24a disposed so as to cover almost the entire tip (lower end) of the short-side wall portion 21f.
　また、ヘッダ側保持金具２４は、下壁部２４ａの幅方向（短手方向）Ｙの両端から板状壁部２１ａ側に向けて延設された一対の第１側壁部２４ｂを備えている。 Further, the header side holding metal fitting 24 includes a pair of first side wall portions 24b extending from both ends in the width direction (short direction) Y of the lower wall portion 24a toward the plate-like wall portion 21a side.
　第１側壁部２４ｂは、長手方向壁部２１ｅの外面２１ｋに沿うように延設されており、先端が板状壁部２１ａの外表面２１ｊよりも若干突出するように形成されている。そして、第１側壁部２４ｂの先端が第２の回路基板４０の回路パターンに半田によって固定される固定部２４ｄとなっている。 The first side wall portion 24b extends along the outer surface 21k of the longitudinal wall portion 21e and is formed so that the tip protrudes slightly from the outer surface 21j of the plate-like wall portion 21a. And the front-end | tip of the 1st side wall part 24b is the fixing | fixed part 24d fixed to the circuit pattern of the 2nd circuit board 40 with solder.
　さらに、一対の第１側壁部２４ｂのうちの一方の第１側壁部２４ｂに連結部２５が連設されている。本実施形態では、連結部２５は、一端（長手方向Ｘの外側）が一方の第１側壁部２４ｂにおける上下方向Ｚの中央部に連設されており、他端（長手方向Ｘの内側）がヘッダ側電源用端子２３の外側部２３ｅに連設されている。 Furthermore, a connecting portion 25 is connected to one first side wall portion 24b of the pair of first side wall portions 24b. In the present embodiment, the connecting portion 25 has one end (outside in the longitudinal direction X) connected to the central portion in the vertical direction Z of the first side wall portion 24b and the other end (inside in the longitudinal direction X). The header side power supply terminal 23 is connected to the outer side 23e.
　さらに、ヘッダ側保持金具２４は、下壁部２４ａの長手方向Ｘの一端（外側）から板状壁部２１ａ側に向けて延設された一対の側片（第２側壁部）２４ｃを備えている。側片２４ｃは、短手方向壁部２１ｆの外面２１ｍに沿うように延設されており、先端が板状壁部２１ａの外表面２１ｊよりも若干突出するように形成されている。そして、側片２４ｃの先端も、第２の回路基板４０の回路パターンに半田によって固定される固定部２４ｄとなっている。 Furthermore, the header side holding metal fitting 24 includes a pair of side pieces (second side wall portions) 24c extending from one end (outside) in the longitudinal direction X of the lower wall portion 24a toward the plate-like wall portion 21a side. Yes. The side piece 24c extends so as to extend along the outer surface 21m of the short-side wall portion 21f, and is formed so that the tip protrudes slightly from the outer surface 21j of the plate-like wall portion 21a. The tip of the side piece 24c is also a fixing portion 24d fixed to the circuit pattern of the second circuit board 40 by solder.
　このように、本実施形態では、ヘッダ側保持金具２４は、４つの固定部２４ｄで第２の回路基板４０の回路パターンに固定されており、３方向（長手方向Ｘの一端および幅方向Ｙの両端）に固定箇所が形成されている。なお、一体化させたヘッダ側電源用端子２３およびヘッダ側保持金具２４は、４つの固定部２４ｄおよび付け根部２２ａで第２の回路基板４０の回路パターンに固定される。 Thus, in this embodiment, the header side holding metal fitting 24 is fixed to the circuit pattern of the second circuit board 40 by the four fixing portions 24d, and is in three directions (one end in the longitudinal direction X and one in the width direction Y). Fixed portions are formed at both ends. The integrated header-side power supply terminal 23 and header-side holding metal 24 are fixed to the circuit pattern of the second circuit board 40 by the four fixing portions 24d and the base portion 22a.
　また、固定部（４つの固定部２４ｄおよび付け根部２３ｆ）とヘッダハウジング２１との間には、隙間が形成されている。隙間は、固定部を半田付けする際の半田の逃げ部としての機能やヘッダハウジング２１の温度が高くなりすぎてしまうのを抑制する放熱部としての機能を有している。 Further, a gap is formed between the fixing portion (four fixing portions 24d and the base portion 23f) and the header housing 21. The gap has a function as a solder escape portion when soldering the fixing portion and a function as a heat dissipation portion that suppresses the temperature of the header housing 21 from becoming too high.
　また、本実施形態では、一対の側片２４ｃは、下壁部２４ａの幅方向（短手方向）Ｙの両端から延設されており、一対の側片２４ｃの間（幅方向Ｙの中央部）には、切り欠き状の隙間２４ｅが形成されている。 Moreover, in this embodiment, a pair of side piece 24c is extended from the both ends of the width direction (short direction) Y of the lower wall part 24a, and between a pair of side pieces 24c (central part of the width direction Y) ) Is formed with a notch-shaped gap 24e.
　さらに、本実施形態では、第１側壁部２４ｂと側片２４ｃとの間（ヘッダハウジング２１の角部）にも切り欠き状の隙間２４ｆが形成されている。 Further, in the present embodiment, a notch-shaped gap 24f is also formed between the first side wall portion 24b and the side piece 24c (corner portion of the header housing 21).
　そして、ヘッダ側電源用端子２３およびヘッダ側保持金具２４は、インサート成形により、ヘッダハウジング２１の長手方向Ｘの両端部に形成された係合溝部２１ｒに埋め込まれた状態で、ヘッダハウジング２１に取り付けられている。 Then, the header-side power supply terminal 23 and the header-side holding metal fitting 24 are attached to the header housing 21 while being embedded in engagement groove portions 21r formed at both ends in the longitudinal direction X of the header housing 21 by insert molding. It has been.
　このとき、切り欠き状の隙間２４ｅ，２４ｆやヘッダ側電源用端子２３とヘッダ側保持金具２４との間の隙間にも樹脂が入り込むようにしている。こうすることで、ヘッダ側電源用端子２３およびヘッダ側保持金具２４のヘッダハウジング２１への固定強度を高めている。 At this time, the resin also enters the notched gaps 24e and 24f and the gap between the header-side power supply terminal 23 and the header-side holding bracket 24. By doing so, the strength of fixing the header-side power supply terminal 23 and the header-side holding bracket 24 to the header housing 21 is increased.
　なお、本実施形態では、一体化させたヘッダ側電源用端子２３およびヘッダ側保持金具２４を、インサート成形によってヘッダハウジング２１に配設しているが、圧入によりヘッダハウジング２１に配設させてもよい。 In the present embodiment, the integrated header-side power supply terminal 23 and header-side holding metal fitting 24 are disposed in the header housing 21 by insert molding, but may be disposed in the header housing 21 by press-fitting.

The socket-side signal terminal 32 includes a base portion (first socket terminal-side fixing portion) 32 a that protrudes from the side surface of the socket housing 31. The base portion 32a is a portion that is fixed to the circuit pattern of the first circuit board 60 with solder. 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).
　ソケット側信号用端子３２は、付け根部３２ａから立上がり、第１の回路基板６０から離れるように延びる立上り部３２ｂを備えている。立上り部３２ｂは、付け根部３２ａから曲がってソケット側信号用端子収容凹部３１ｊ内に入り、長手方向壁部３１ｈの内面３１ｕに沿って延びている。 The socket-side signal terminal 32 includes 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 is bent from the base portion 32a, enters the socket-side signal terminal accommodating recess 31j, and extends along the inner surface 31u of the longitudinal wall portion 31h.
　ソケット側信号用端子３２は、立上り部３２ｂの上端にその一方端が連続する反転Ｕ字状部３２ｃを備えている。反転Ｕ字状部３２ｃは、文字「Ｕ」が上下逆さまに配置された形状を有している。なお、反転Ｕ字状部３２ｃは、先端面３２ｎと、当該先端面３２ｎの長手方向Ｘ両側に連設される傾斜面３２ｐとを有しており、水平断面視で略台形状に突出する突状に形成されている。 The socket-side signal terminal 32 includes an inverted U-shaped portion 32c whose one end is 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.

It is formed in a shape.
　ソケット側信号用端子３２は、反転Ｕ字状部３２ｃの他方端に連続する係止部３２ｄを備えている。本実施形態では、係止部３２ｄは、ソケット側信号用端子３２におけるソケットハウジング３１の長手方向Ｘの一端から他端にかけて形成されている。すなわち、ソケット側信号用端子３２の幅方向全体に亘って、段差状の係止部３２ｄが形成されている。 The socket-side signal terminal 32 includes a locking portion 32d continuous with the other end of the inverted U-shaped portion 32c. In the present embodiment, the locking portion 32 d 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 32 d is formed over the entire width direction of the socket-side signal terminal 32.
　係止部３２ｄは、上述したように、ヘッダ側信号用端子２２がソケット側信号用端子３２から引き抜かれるときに、被係止部２２ｅの移動を抑制する部分として機能する。つまり、ソケット側信号用端子３２の係止部３２ｄは、ヘッダ側信号用端子２２の被係止部２２ｅに当接し、被係止部２２ｅを係止し得る。ソケット側信号用端子３２の係止部３２ｄおよびヘッダ側信号用端子２２の被係止部２２ｅは、所定値以上の外力を加えることにより、係止を解除することが可能なロック機構を構成している。 As described above, the locking portion 32d functions as a portion that suppresses the movement of the locked portion 22e when the header-side signal terminal 22 is pulled out from the socket-side signal terminal 32. That is, the locking portion 32d of the socket-side signal terminal 32 can abut on the locked portion 22e of the header-side signal terminal 22 to lock the locked portion 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.

Note that the socket-side signal terminal 32 may include an arcuate portion instead of the inclined portion 32f.
　ソケット側信号用端子３２は、図２３および図２４に示すように、傾斜部３２ｆに連続する対向部３２ｚを備えている。対向部３２ｚは、次に説明する平坦部３２ｇ、第１の斜め部３２ｈ、円弧状部３２ｉ、第２の斜め部３２ｊ、円弧状突起部３２ｋ、および先端部３２ｍを含んでいる。対向部３２ｚは、具体的には次のようなものである。 As shown in FIGS. 23 and 24, the socket-side signal terminal 32 includes a facing portion 32z that is continuous with the inclined portion 32f. The facing part 32z includes a flat part 32g, a first oblique part 32h, an arcuate part 32i, a second oblique part 32j, an arcuate protrusion 32k, and a tip part 32m, which will be described next. Specifically, the facing portion 32z is as follows.
　対向部３２ｚは、傾斜部３２ｆの下端に連続する平坦部３２ｇを備えている。平坦部３２ｇは、図２３に示すように、立下り部３２ｅから離れるように、第１の回路基板６０の主表面Ｍに沿って延びている。ただし、平坦部３２ｇは、主表面Ｍに平行である必要はない。平坦部３２ｇは、後述するばね部のばね長を大きくするために設けられている。 The facing portion 32z includes a flat portion 32g continuous to the lower end of the inclined portion 32f. As shown in FIG. 23, 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 need to be parallel to the main surface M. The flat portion 32g is provided to increase the spring length of a spring portion described later.
　対向部３２ｚは、図２３に示すように、平坦部３２ｇに連続し、第１の回路基板６０の主表面Ｍに対して斜め方向に延びる第１の斜め部３２ｈを備えている。第１の斜め部３２ｈは、第１の回路基板６０から離れるにしたがって、立下り部３２ｅから離れるように延びている。第１の斜め部３２ｈは円弧状部３２ｉに連続している。円弧状部３２ｉは、立下り部３２ｅから離れるように突出する湾曲部である。円弧状部３２ｉは、第１の回路基板６０の主表面Ｍに対して斜め方向に延びる第２の斜め部３２ｊに連続している。第２の斜め部３２ｊは、第１の回路基板６０から離れるにしたがって、立下り部３２ｅに近づくように延びている。したがって、第２の斜め部３２ｊは、第１の斜め部３２ｈの上方に位置付けられている。 As shown in FIG. 23, the facing portion 32 z includes a first inclined portion 32 h that is continuous with the flat portion 32 g and extends obliquely with respect to the main surface M of the first circuit board 60. The first oblique portion 32h extends away from the falling portion 32e as it is away from the first circuit board 60. The first oblique portion 32h is continuous with the arc-shaped portion 32i. The arc-shaped portion 32i is a curved portion that protrudes away from the falling portion 32e. The arc-shaped portion 32 i is continuous with the second oblique portion 32 j extending in the oblique direction with respect to the main surface M of the first circuit board 60. The second oblique portion 32j extends so as to approach the falling portion 32e as the distance from the first circuit board 60 increases. Therefore, the second oblique portion 32j is positioned above the first oblique portion 32h.
　対向部３２ｚは、図２３に示すように、第２の斜め部３２ｊの上端に、その一方端が連続する円弧状突起部３２ｋを備えている。円弧状突起部３２ｋは、先端面３２ｒと、当該先端面３２ｒの長手方向Ｘ両側に連設される傾斜面３２ｓとを有しており、水平断面視で略台形状に突出する突状に形成されている。 As shown in FIG. 23, the opposing portion 32z includes an arc-shaped protrusion 32k having one end continuous to the upper end of the second oblique portion 32j. The arc-shaped protruding portion 32k has a tip surface 32r and inclined surfaces 32s provided on both sides in the longitudinal direction X of the tip surface 32r, and is formed in a protruding shape that protrudes in a substantially trapezoidal shape in a horizontal sectional view. Has been.
　円弧状突起部３２ｋは、図２３に示すように、ヘッダ側信号用端子２２の凹部２２ｃに嵌まり込む。円弧状突起部３２ｋの他方端は先端部３２ｍに連続している。先端部３２ｍは、第２の斜め部３２ｊにほぼ平行に延びている。図２３および図２４から分かるように、対向部３２ｚ（３２ｇ，３２ｈ，３２ｉ，３２ｊ，３２ｋ，３２ｍ）は、傾斜部３２ｆの下端に連続し、全体として立下り部３２ｅに対向している。 As shown in FIG. 23, the arc-shaped protrusion 32k is fitted 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 distal end 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) is continuous with the lower end of the inclined portion 32f and faces the falling portion 32e as a whole.
　本実施形態においては、ヘッダ２０とソケット３０とが嵌合する時には、図２４に示すように、ヘッダ側信号用端子２２は、反転Ｕ字状部３２ｃと円弧状突起部３２ｋとの間に挿入される。このとき、立下り部３２ｅ、傾斜部３２ｆ、平坦部３２ｇ、第１の斜め部３２ｈ、円弧状部３２ｉ、第２の斜め部３２ｊ、円弧状突起部３２ｋ、および先端部３２ｍは、一体となって、ばね部として機能する。ばね部（３２ｅ，３２ｆ，３２ｇ，３２ｈ，３２ｉ，３２ｊ，３２ｋ，３２ｍ）は、ヘッダ側信号用端子２２の凸部がソケット側信号用端子３２の凹部に挿入されると、弾性変形する。それにより、立下り部３２ｅおよび反転Ｕ字状部３２ｃとの２つの部分と円弧状突起部３２ｋとの間の距離が大きくなる。このとき、ヘッダ側信号用端子２２の被係止部２２ｅが、ソケット側信号用端子３２の係止部３２ｄよりも下方に挿入される。それにより、ソケット側信号用端子３２の円弧状突起部３２ｋがヘッダ側信号用端子２２の凹部２２ｃに嵌まり込む。 In this embodiment, when the header 20 and the socket 30 are fitted, as shown in FIG. 24, the header-side signal terminal 22 is inserted between the inverted U-shaped portion 32c and the arc-shaped protruding portion 32k. Is done. At this time, the falling part 32e, the inclined part 32f, the flat part 32g, the first oblique part 32h, the arcuate part 32i, the second oblique part 32j, the arcuate protrusion part 32k, and the tip part 32m are integrated. And function as a spring part. 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. As a result, the distance between the two portions of the falling portion 32e and the inverted U-shaped portion 32c and the arc-shaped protruding portion 32k is increased. At this time, the locked portion 22 e of the header side signal terminal 22 is inserted below the locking portion 32 d of the socket side signal terminal 32. As a result, the arc-shaped protrusion 32 k of the socket-side signal terminal 32 is fitted into the recess 22 c of the header-side signal terminal 22.
　ヘッダ側信号用端子２２がソケット側信号用端子３２に嵌合した状態では、弾性変形したばね部に復元力が生じる。この復元力により、円弧状突起部３２ｋは、ヘッダ側信号用端子２２を立下り部３２ｅおよび反転Ｕ字状部３２ｃのそれぞれに対して押し付ける。それにより、ヘッダ側信号用端子２２は、ソケット側信号用端子３２に挟持される。このとき、ヘッダ側信号用端子２２は、ソケット側信号用端子３２の反転Ｕ字状部３２ｃ、立下り部３２ｅ、および円弧状突起部３２ｋのそれぞれに接触する。 In the state where the header side signal terminal 22 is fitted to the socket side signal terminal 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, 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 protruding portion 32k of the socket-side signal terminal 32.
　具体的には、図２３および図２４に示すように、ヘッダ側信号用端子２２の先端部２２ｄが、ソケット側信号用端子３２の立下り部３２ｅに接触する。すなわち、ソケット側信号用端子３２の接点部（第１のソケット端子側接点部）Ｒ１およびヘッダ側信号用端子２２の接点部（第１のヘッダ端子側接点部）Ｒ１が互いに接触する。 Specifically, as shown in FIGS. 23 and 24, the leading end 22 d of the header-side signal terminal 22 contacts the falling portion 32 e 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 are in contact with each other.
　また、ヘッダ側信号用端子２２の凹部２２ｃは、ソケット側信号用端子３２の円弧状突起部３２ｋに接触する。すなわち、ソケット側信号用端子３２の接点部（第１のソケット端子側接点部）Ｒ２およびヘッダ側信号用端子２２の接点部（第１のヘッダ端子側接点部）Ｒ２が互いに接触する。 Also, the recess 22c of the header signal terminal 22 contacts the arcuate protrusion 32k of the socket 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 are in contact with each other.
　このように、ヘッダ側信号用端子２２とソケット側信号用端子３２は、幅方向Ｙに離間した複数の接点（接点部Ｒ１および接点部Ｒ２の２つの接点部）で接触する。そのため、ヘッダ側信号用端子２２とソケット側信号用端子３２との電気的接続の信頼性が高い。 Thus, the header-side signal terminal 22 and the socket-side signal terminal 32 are in contact with each other at a plurality of contact points (two contact portions of the contact portion R1 and the contact portion 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.
　さらに、本実施形態では、互いに接触するソケット側信号用端子３２の接点部Ｒ２およびヘッダ側信号用端子２２の接点部Ｒ２のうちいずれか一方の接点部であるヘッダ側信号用端子２２の接点部Ｒ２に、凹部２２ｃが形成されている。そして、他方の接点部であるソケット側信号用端子３２の接点部Ｒ２が、凹部２２ｃにおけるソケットハウジング３１の長手方向Ｘ両端部で接触するようにしている。 Furthermore, in this embodiment, the contact portion of the header-side signal terminal 22 that 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 that are in contact with each other. A recess 22c is formed in R2. The contact portion R2 of the socket-side signal terminal 32, which is the other contact portion, is in contact with both ends in the longitudinal direction X of the socket housing 31 in the recess 22c.
　具体的には、ソケット側信号用端子３２の円弧状突起部３２ｋが凹部２２ｃに嵌まり込む際に、円弧状突起部３２ｋの先端面３２ｒと傾斜面３２ｓとの境界部分が傾斜面２２ｈにそれぞれ接触している。このように、本実施形態では、ソケット側信号用端子３２の接点部Ｒ２が、ヘッダ側信号用端子２２の接点部Ｒ２に２点で接触するようにしている。 Specifically, when the arcuate protrusion 32k of the socket-side signal terminal 32 is fitted into the recess 22c, the boundary between the tip surface 32r and the inclined surface 32s of the arcuate protrusion 32k is formed on the inclined surface 22h. In contact. Thus, in the present embodiment, the contact portion R2 of the socket-side signal terminal 32 is in contact with the contact portion R2 of the header-side signal terminal 22 at two points.
　なお、ばね部の弾性変形に起因して、接点部Ｒ１、接点部Ｒ２以外に、平坦部３２ｇと第１の斜め部３２ｈとの境界部が第１の回路基板６０に接点部Ｒ５で接触する場合もある。 In addition, 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 portion R1 and the contact portion R2. In some cases.
　このように、本実施形態のヘッダ側信号用端子２２とソケット側信号用端子３２とは、幅方向Ｙに離間した複数の接点で接している。しかしながら、本開示のヘッダ側信号用端子とソケット側信号用端子とは、例えば、ヘッダ側信号用端子の内側面とソケット側信号用端子の対向部との１接点のみで接触するものであってもよい。 Thus, the header-side signal terminal 22 and the socket-side signal terminal 32 of the present embodiment are in contact with each other at a plurality of contacts spaced in the width direction Y. However, the header-side signal terminal and the socket-side signal terminal of the present disclosure are, for example, in contact with only one contact point between the inner side surface of the header-side signal terminal and the facing portion of the socket-side signal terminal. Also good.
　なお、ばね部（３２ｅ，３２ｆ，３２ｇ，３２ｈ，３２ｉ，３２ｊ，３２ｋ，３２ｍ）は、Ｕ字状部（３２ｅ，３２ｆ，３２ｇ，３２ｈ，３２ｉ，３２ｊ）と、当該Ｕ字状部（３２ｅ，３２ｆ，３２ｇ，３２ｈ，３２ｉ，３２ｊ）の一端（３２ｊ側）に連設された自由端部（３２ｋ，３２ｍ）とで構成されている。そして、自由端部（３２ｋ，３２ｍ）の円弧状突起部３２ｋに、ソケット側信号用端子３２の接点部Ｒ２が設けられている。 The spring portions (32e, 32f, 32g, 32h, 32i, 32j, 32k, 32m) are formed of a U-shaped portion (32e, 32f, 32g, 32h, 32i, 32j) and the U-shaped portion (32e, 32j, 32j). 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 protrusion 32k of the free end (32k, 32m).
　このように、ソケット側信号用端子３２は、Ｕ字状部（３２ｅ，３２ｆ，３２ｇ，３２ｈ，３２ｉ，３２ｊ）を有しており、当該Ｕ字状部（３２ｅ，３２ｆ，３２ｇ，３２ｈ，３２ｉ，３２ｊ）の一端（３２ｊ側）には、接点部Ｒ２が設けられる自由端部（３２ｋ，３２ｍ）が連設されている。 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) is connected to a free end portion (32k, 32m) provided with a contact portion R2 at one end (32j side).
　ソケット側信号用端子３２は、所定厚さを持った帯状の金属材を湾曲成形することにより形成することができる。 The socket-side signal terminal 32 can be formed by bending a band-shaped metal material having a predetermined thickness.
　また、ソケット側信号用端子３２は、ソケット３０を組み立てる際に、ソケットハウジング３１の裏面側（図１４の下側）からソケット側信号用端子収容部３１ｆに挿入（圧入）することで、ソケットハウジング３１に装着されている。 Further, when assembling the socket 30, the socket-side signal terminal 32 is inserted (press-fitted) into the socket-side signal terminal accommodating portion 31f from the back surface side (the lower side in FIG. 14) of the socket housing 31, thereby 31 is attached.
　なお、ソケット側信号用端子３２をソケットハウジング３１にインサート成形する等して、ソケット側信号用端子３２をソケットハウジング３１に装着するようにしてもよい。 Note that the socket-side signal terminal 32 may be attached to the socket housing 31 by insert molding the socket-side signal terminal 32 into the socket housing 31 or the like.
　次に、図１９および図２０を参照しながら、ソケット側電源用端子３３の構成を説明する。 Next, the configuration of the socket-side power supply terminal 33 will be described with reference to FIGS. 19 and 20.
　ソケット側電源用端子３３は、金属成形により製造されており、導電体である。そして、ソケット側電源用端子３３は、ソケットハウジング３１の側面から突出する付け根部（第２のソケット端子側固定部）３３ａを備えている。付け根部３３ａは、第１の回路基板６０の回路パターンに半田によって固定される部位である。また、付け根部３３ａの下面は、第１の回路基板６０の主表面Ｍに沿って延び、ソケットハウジング３１の底面（板状壁部３１ａの裏面）と同一平面内に位置付けられている。 The socket-side power supply terminal 33 is manufactured by metal forming and is a conductor. The socket-side power supply terminal 33 includes a base portion (second socket terminal-side fixing portion) 33 a that protrudes from the side surface of the socket housing 31. The base portion 33a is a portion that is fixed to the circuit pattern of the first circuit board 60 with solder. The bottom surface of the base portion 33a 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).
　ソケット側電源用端子３３は、付け根部３３ａから立上がり、第１の回路基板６０から離れるように延びる立上り部３３ｂを備えている。立上り部３３ｂは、付け根部３３ａから曲がってソケット側電源用端子収容凹部３１ｋ内に入り、長手方向壁部３１ｈの内面３１ｕに沿って延びている。 The socket-side power supply terminal 33 includes a rising portion 33 b that rises from the base portion 33 a and extends away from the first circuit board 60. The rising portion 33b is bent from the base portion 33a, enters the socket-side power terminal accommodating recess 31k, and extends along the inner surface 31u of the longitudinal wall portion 31h.
　ソケット側電源用端子３３は、立上り部３３ｂの上端にその一方端が連続する反転Ｕ字状部３３ｃを備えている。反転Ｕ字状部３３ｃは、文字「Ｕ」が上下逆さまに配置された形状を有している。なお、反転Ｕ字状部３３ｃは、先端面３３ｒと、当該先端面３３ｒの長手方向Ｘ両側に連設される傾斜面３３ｓとを有しており、水平断面視で略台形状に突出する突状に形成されている。 The socket-side power supply terminal 33 includes an inverted U-shaped portion 33c whose one end is continuous with the upper end of the rising portion 33b. The inverted U-shaped portion 33c has a shape in which the letter “U” is arranged upside down. The inverted U-shaped portion 33c has a tip surface 33r and inclined surfaces 33s provided on both sides in the longitudinal direction X of the tip surface 33r, and protrudes in a substantially trapezoidal shape in a horizontal sectional view. It is formed in a shape.
　ソケット側電源用端子３３は、反転Ｕ字状部３３ｃの他方端に連続する係止部３３ｄを備えている。係止部３３ｄは、上述したように、ヘッダ側電源用端子２３がソケット側電源用端子３３から引き抜かれるときに、被係止部２３ｄの移動を抑制する部分として機能する。つまり、ソケット側電源用端子３３の係止部３３ｄは、ヘッダ側電源用端子２３の被係止部２３ｄに当接し、被係止部２３ｄを係止し得る。ソケット側電源用端子３３の係止部３３ｄおよびヘッダ側電源用端子２３の被係止部２３ｄは、所定値以上の外力を加えることにより、係止を解除することが可能なロック機構を構成している。 The socket-side power supply terminal 33 includes a locking portion 33d that is continuous with the other end of the inverted U-shaped portion 33c. 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 to 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 lock mechanism that can be released by applying an external force of a predetermined value or more. ing.
　係止部３３ｄは、ソケット側電源用端子３３の厚さを部分的に異ならせる母材の圧延により製造されてもよいが、ソケット側電源用端子３３の母材を厚さ方向に曲げる成形により製造されてもよい。 The locking portion 33d may be manufactured by rolling a base material that partially varies the thickness of the socket-side power supply terminal 33, but is formed by bending the base material of the socket-side power supply terminal 33 in the thickness direction. May be manufactured.
　また、ソケット側電源用端子３３は、係止部３３ｄに連続し、立上り部３３ｂにほぼ平行に延びる立下り部３３ｅを有している。 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.
　そして、ソケット側電源用端子３３は、立下り部３３ｅの下端に連続する傾斜部３３ｆを備えている。なお、ソケット側電源用端子３３が傾斜部３３ｆにかえて円弧状部を備えるようにしてもよい。 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 an arcuate portion instead of the inclined portion 33f.
　ソケット側電源用端子３３は、図２５および図２６に示すように、傾斜部３３ｆに連続する対向部３３ｚを備えている。対向部３３ｚは、次に説明する平坦部３３ｇ、第１の斜め部３３ｈ、円弧状部３３ｉ、第２の斜め部３３ｊ、円弧状突起部３３ｋ、および先端部３３ｍを含んでいる。対向部３３ｚは、具体的には次のようなものである。 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 part 33z includes a flat part 33g, a first oblique part 33h, an arcuate part 33i, a second oblique part 33j, an arcuate protrusion 33k, and a tip part 33m, which will be described next. The facing portion 33z is specifically as follows.
　対向部３３ｚは、傾斜部３３ｆの下端に連続する平坦部３３ｇを備えている。平坦部３３ｇは、図２５に示すように、立下り部３３ｅから離れるように、第１の回路基板６０の主表面Ｍに沿って延びている。ただし、平坦部３３ｇは、主表面Ｍに平行である必要はない。平坦部３３ｇは、後述するばね部のばね長を大きくするために設けられている。 The facing portion 33z includes a flat portion 33g continuous to the lower end of the inclined portion 33f. As shown in FIG. 25, the flat portion 33g extends along the main surface M of the first circuit board 60 so as to be separated from the falling portion 33e. However, the flat portion 33g does not need to be parallel to the main surface M. The flat portion 33g is provided to increase the spring length of a spring portion described later.
　対向部３３ｚは、図２５に示すように、平坦部３３ｇに連続し、第１の回路基板６０の主表面Ｍに対して斜め方向に延びる第１の斜め部３３ｈを備えている。第１の斜め部３３ｈは、第１の回路基板６０から離れるにしたがって、立下り部３３ｅから離れるように延びている。第１の斜め部３３ｈは円弧状部３３ｉに連続している。円弧状部３３ｉは、立下り部３３ｅから離れるように突出する湾曲部である。円弧状部３３ｉは、第１の回路基板６０の主表面Ｍに対して斜め方向に延びる第２の斜め部３３ｊに連続している。第２の斜め部３３ｊは、第１の回路基板６０から離れるにしたがって、立下り部３３ｅに近づくように延びている。したがって、第２の斜め部３３ｊは、第１の斜め部３３ｈの上方に位置付けられている。 As shown in FIG. 25, the facing portion 33 z includes a first oblique portion 33 h that is continuous with the flat portion 33 g and extends obliquely with respect to the main surface M of the first circuit board 60. The first oblique portion 33h extends away from the falling portion 33e as the distance from the first circuit board 60 increases. The first oblique portion 33h is continuous with the arc-shaped portion 33i. The arc-shaped portion 33i is a curved portion that protrudes away from the falling portion 33e. The arc-shaped portion 33 i is continuous with the second oblique portion 33 j extending in the oblique direction with respect to the main surface M of the first circuit board 60. The second oblique portion 33j extends so as to approach the falling portion 33e as the distance from the first circuit board 60 increases. Therefore, the second oblique portion 33j is positioned above the first oblique portion 33h.
　対向部３３ｚは、図２５に示すように、第２の斜め部３３ｊの上端に、その一方端が連続する円弧状突起部３３ｋを備えている。円弧状突起部３３ｋは、先端面３３ｖと、当該先端面３３ｖの長手方向Ｘ両側に連設される傾斜面３３ｗとを有しており、水平断面視で略台形状に突出する突状に形成されている。 As shown in FIG. 25, the facing portion 33z includes an arc-shaped protrusion 33k having one end continuous at the upper end of the second oblique portion 33j. The arc-shaped protrusion 33k has a tip surface 33v and inclined surfaces 33w provided on both sides in the longitudinal direction X of the tip surface 33v, and is formed in a protruding shape that protrudes in a substantially trapezoidal shape in a horizontal sectional view. Has been.
　円弧状突起部３３ｋは、図２５に示すように、ヘッダ側電源用端子２３の凹部２３ｂに嵌まり込む。円弧状突起部３３ｋの他方端は先端部３３ｍに連続している。先端部３３ｍは、第２の斜め部３３ｊにほぼ平行に延びている。図２５および図２６から分かるように、対向部３３ｚ（３３ｇ，３３ｈ，３３ｉ，３３ｊ，３３ｋ，３３ｍ）は、傾斜部３３ｆの下端に連続し、全体として立下り部３３ｅに対向している。 As shown in FIG. 25, the arc-shaped protrusion 33k is fitted into the recess 23b of the header-side power supply terminal 23. The other end of the arc-shaped protrusion 33k is continuous with the tip 33m. The distal end 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) is continuous with the lower end of the inclined portion 33f and faces the falling portion 33e as a whole.
　このように、本実施形態では、ソケット側信号用端子３２の側面形状とソケット側電源用端子３３の側面形状とが略同一形状をしている（図１８（ａ）および図２０（ａ）参照）。 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 are substantially the same shape (see FIGS. 18A and 20A). ).
　そして、本実施形態においては、ヘッダ２０とソケット３０とが嵌合する時には、図２６に示すように、ヘッダ側電源用端子２３は、ソケット側信号用端子３２と同様に、反転Ｕ字状部３３ｃと円弧状突起部３３ｋとの間に挿入される。このとき、立下り部３３ｅ、傾斜部３３ｆ、平坦部３３ｇ、第１の斜め部３３ｈ、円弧状部３３ｉ、第２の斜め部３３ｊ、円弧状突起部３３ｋ、および先端部３３ｍは、一体となって、ばね部として機能する。ばね部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ，３３ｋ，３３ｍ）は、ヘッダ側電源用端子２３の凸部がソケット側電源用端子３３の凹部に挿入されると、弾性変形する。 In this embodiment, when the header 20 and the socket 30 are fitted, as shown in FIG. 26, the header-side power supply terminal 23 is the inverted U-shaped portion, like the socket-side signal terminal 32. It is inserted between 33c and arcuate projection 33k. At this time, the falling part 33e, the inclined part 33f, the flat part 33g, the first oblique part 33h, the arcuate part 33i, the second oblique part 33j, the arcuate protrusion 33k, and the tip part 33m are integrated. And function as a spring part. The spring portions (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) are elastically deformed when the convex portion of the header-side power supply terminal 23 is inserted into the concave portion of the socket-side power supply terminal 33.
　なお、本実施形態では、傾斜部３３ｆから先端部３３ｍまでの部位における幅（長手方向Ｘに沿った幅）が、立上り部３３ｂ、反転Ｕ字状部３３ｃ、係止部３３ｄおよび立下り部３３ｅの幅（長手方向Ｘに沿った幅）よりも狭くなっている。したがって、ばね部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ，３３ｋ，３３ｍ）は、傾斜部３３ｆから先端部３３ｍまでの部分が特に弾性変形し易くなっている。 In the present embodiment, the width (width along the longitudinal direction X) 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. It is narrower than the width (width along the longitudinal direction X). Accordingly, the spring portions (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) are particularly easily elastically deformed from the inclined portion 33f to the tip portion 33m.
　そして、ばね部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ，３３ｋ，３３ｍ）が弾性変形すると、立下り部３３ｅおよび反転Ｕ字状部３３ｃとの２つの部分と円弧状突起部３３ｋとの間の距離が大きくなる。このとき、ヘッダ側電源用端子２３の被係止部２３ｄが、ソケット側電源用端子３３の係止部３３ｄよりも下方に挿入される。それにより、ソケット側電源用端子３３の円弧状突起部３３ｋがヘッダ側電源用端子２３の凹部２３ｂに嵌まり込む。 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 protruding portion 33k The distance between them increases. At this time, the locked portion 23 d of the header-side power supply terminal 23 is inserted below the locking portion 33 d of the socket-side power supply terminal 33. As a result, the arc-shaped protrusion 33 k of the socket-side power supply terminal 33 fits into the recess 23 b of the header-side power supply terminal 23.
　ヘッダ側電源用端子２３がソケット側電源用端子３３に嵌合した状態では、弾性変形したばね部に復元力が生じる。この復元力により、円弧状突起部３３ｋは、ヘッダ側電源用端子２３を立下り部３３ｅおよび反転Ｕ字状部３３ｃのそれぞれに対して押し付ける。それにより、ヘッダ側電源用端子２３は、ソケット側電源用端子３３に挟持される。このとき、ヘッダ側電源用端子２３は、ソケット側電源用端子３３の反転Ｕ字状部３３ｃ、立下り部３３ｅ、および円弧状突起部３３ｋのそれぞれに接触する。 In a state where the header-side power supply terminal 23 is fitted to the socket-side power supply terminal 33, a restoring force is generated in the elastically deformed spring portion. Due to this restoring force, the arc-shaped protruding portion 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 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 comes into contact with each of the inverted U-shaped portion 33c, the falling portion 33e, and the arc-shaped protrusion 33k of the socket-side power supply terminal 33.
　具体的には、図２５および図２６に示すように、ヘッダ側電源用端子２３の先端部２３ｃが、ソケット側電源用端子３３の立下り部３３ｅに接触する。すなわち、ソケット側電源用端子３３の接点部（第２のソケット端子側接点部）Ｒ３およびヘッダ側電源用端子２３の接点部（第２のヘッダ端子側接点部）Ｒ３が互いに接触する。 Specifically, as shown in FIG. 25 and FIG. 26, the leading 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 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 are in contact with each other.
　また、ヘッダ側電源用端子２３の凹部２３ｂは、ソケット側電源用端子３３の円弧状突起部３３ｋに接触する。すなわち、ソケット側電源用端子３３の接点部（第２のソケット端子側接点部）Ｒ４およびヘッダ側電源用端子２３の接点部（第２のヘッダ端子側接点部）Ｒ４が互いに接触する。 Further, the recess 23 b of the header-side power supply terminal 23 contacts the arcuate protrusion 33 k of the socket-side power supply terminal 33. 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 are in contact with each other.
　このように、ヘッダ側電源用端子２３とソケット側電源用端子３３は、幅方向Ｙに離間した複数の接点（接点部Ｒ３および接点部Ｒ４の２つの接点部）で接触する。そのため、ヘッダ側電源用端子２３とソケット側電源用端子３３との電気的接続の信頼性が高い。 Thus, 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 portions of the contact portion R3 and the contact portion R4) spaced 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.
　そして、ソケット側電源用端子３３の２箇所に設けられた接点部Ｒ３および接点部Ｒ４は、接点部Ｒ３が接点部Ｒ４よりも付け根部（第２のソケット端子側固定部）３３ａに近い側に位置している。 The contact portion R3 and the contact portion R4 provided at two locations of the socket-side power supply terminal 33 are closer to the base portion (second socket terminal side fixing portion) 33a than the contact portion R4. positioned.
　そして、本実施形態では、接点部Ｒ３および接点部Ｒ４のうち付け根部（第２のソケット端子側固定部）３３ａに近い側に位置する接点部Ｒ３の断面積が、他方側に位置する接点部Ｒ４の断面積よりも大きくなるようにしている。かかる構成は、例えば、ソケット側電源用端子３３の接点部Ｒ３および接点部Ｒ４における幅（長手方向Ｘに沿った幅）や厚さ（板厚）を適宜設定することで得ることができる。 In the present embodiment, the contact portion R3 and the contact portion R4 are located on the side closer to the base portion (second socket terminal side fixing portion) 33a. The cross-sectional area of R4 is made larger. Such a configuration can be obtained, for example, by appropriately setting the width (width along the longitudinal direction X) and thickness (plate thickness) at the contact portion R3 and the contact portion R4 of the socket-side power supply terminal 33.
　本実施形態では、ソケット側電源用端子３３の接点部Ｒ３における幅（長手方向Ｘに沿った幅）が、接点部Ｒ４における幅（長手方向Ｘに沿った幅）よりも広くなるようにしている。 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 wider than the width (width along the longitudinal direction X) of the contact portion R4. .
　また、本実施形態では、付け根部３３ａは、ソケットハウジング３１の長手方向Ｘに沿った幅が、立上り部３３ｂの長手方向Ｘに沿った幅よりも狭くなるように形成されている。そして、付け根部３３ａは、立上り部３３ｂの長手方向Ｘの外側の部分（Ｘ方向で隣り合うソケット側信号用端子３２から離れた側）に連設されている。 In the present embodiment, the base portion 33a is formed so 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 base portion 33a is connected to the outer portion of the rising portion 33b in the longitudinal direction X (the side away from the socket-side signal terminal 32 adjacent in the X direction).
　さらに、付け根部３３ａは、ソケット側信号用端子３２およびソケット側電源用端子３３をソケットハウジング３１に配置した状態で、接点部Ｒ３および接点部Ｒ４に対して付け根部（第１のソケット端子側固定部）３２ａから離れる方向にオフセットしている。 Further, the base portion 33a is connected to the base portion (first socket terminal side fixed portion) with respect to the contact portion R3 and the contact portion R4 in a state where the socket side signal terminal 32 and the socket side power supply terminal 33 are arranged in the socket housing 31. Part) is offset in a direction away from 32a.
　すなわち、付け根部（第２のソケット端子側固定部）３３ａは、立上り部３３ｂよりも長手方向Ｘの外側に突出した状態で立上り部３３ｂに連設されている。 That is, the base 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.
　こうすることで、ソケット側信号用端子３２およびソケット側電源用端子３３をソケットハウジング３１に配置した状態で、付け根部（第１のソケット端子側固定部）３２ａと付け根部（第２のソケット端子側固定部）３３ａとの間の距離が、ソケット側信号用端子３２の接点部（第１のソケット端子側接点部）Ｒ１，Ｒ２と、ソケット側電源用端子３３の接点部（第２のソケット端子側接点部）Ｒ３，Ｒ４との間の距離よりも大きくなるようにしている。 By doing so, in the state where the socket-side signal terminal 32 and the socket-side power supply terminal 33 are arranged in the socket housing 31, the base portion (first socket terminal side fixing portion) 32a and the base portion (second socket terminal) Distance between the socket side signal terminal 32 and the contact part (second socket) of the socket side power supply terminal 33 and the contact part (first socket terminal side contact part) R1, R2. The distance between the terminal-side contact portions (R3, R4) is larger.
　こうすれば、ソケット側電源用端子（第２のソケット端子）３３とソケット側信号用端子（第１のソケット端子）３２との絶縁距離（Ｘ方向で互いに隣り合う付け根部３３ａと付け根部３２ａとの距離）を長くすることができる。 In this way, the insulation distance between the socket-side power terminal (second socket terminal) 33 and the socket-side signal terminal (first socket terminal) 32 (the root portion 33a and the root portion 32a adjacent to each other in the X direction) Can be made longer.
　なお、付け根部（第２のソケット端子側固定部）３３ａを立上り部３３ｂよりも長手方向Ｘの外側に突出させずに、付け根部（第２のソケット端子側固定部）３３ａの幅を小さくすることで、絶縁距離を長くすることも可能である。 Note that the width of the base portion (second socket terminal side fixing portion) 33a is reduced without projecting the base portion (second socket terminal side fixing portion) 33a outward of the rising portion 33b in the longitudinal direction X. Thus, it is possible to increase the insulation distance.
　また、上述したように、ソケット側信号用端子３２の側面形状とソケット側電源用端子３３の側面形状とが略同一形状をしている。 Further, as described above, 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.
　さらに、ソケット側信号用端子３２およびソケット側電源用端子３３は、ソケットハウジング３１の長手方向Ｘに沿って列状に配設されている。 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.
　そして、ソケット側電源用端子３３は、ソケットハウジング３１の長手方向Ｘに沿った幅が、ソケット側信号用端子３２の長手方向Ｘに沿った幅よりも広くなるように形成されている。 The socket-side power terminal 33 is formed such that the width along the longitudinal direction X of the socket housing 31 is wider than the width along the longitudinal direction X of the socket-side signal terminal 32.
　すなわち、本実施形態では、ソケット側電源用端子３３よりもソケットハウジング３１の長手方向Ｘの幅が狭いソケット側信号用端子３２を有するようにしている。なお、本実施形態では、全てのソケット側信号用端子３２が、ソケット側電源用端子３３よりもソケットハウジング３１の長手方向Ｘの幅が狭くなっている。 That is, in this embodiment, the socket-side signal terminal 32 is narrower in the longitudinal direction X of the socket housing 31 than the socket-side power supply terminal 33. In the present embodiment, all the socket-side signal terminals 32 are narrower in the longitudinal direction X of the socket housing 31 than the socket-side power terminals 33.
　さらに、本実施形態では、ソケット側電源用端子３３の厚さ（板厚）を、ソケット側信号用端子３２の厚さ（板厚）よりも薄くなるようにしている。 Furthermore, in the present embodiment, the thickness (plate thickness) of the socket-side power supply terminal 33 is made thinner than the thickness (plate thickness) of the socket-side signal terminal 32.
　また、係止部３３ｄが、ソケット側電源用端子３３におけるソケットハウジング３１の長手方向Ｘの一端から他端にかけて形成されている。すなわち、幅広のソケット側電源用端子３３の幅方向全体に亘って、段差状の係止部３３ｄを形成している。こうすることで、ヘッダ側電源用端子２３の被係止部２３ｄおよびソケット側電源用端子３３の係止部３３ｄによるロック力を向上させることができる。また、ヘッダ２０およびソケット３０の挿抜を繰り返した際にも、係止部３３ｄが摩耗しにくくなるため、製品の長寿命化を図ることが可能となる。 Moreover, the latching | locking part 33d is formed from the one end of the longitudinal direction X of the socket housing 31 in the socket side power supply terminal 33 to the other end. That is, a step-shaped locking portion 33 d is formed over the entire width direction of the wide socket-side power supply terminal 33. By doing so, the locking force by 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 improved. In addition, when the insertion and removal of the header 20 and the socket 30 are repeated, the engaging portion 33d is less likely to be worn, so that the product life can be extended.
　さらに、本実施形態では、ばね部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ，３３ｋ，３３ｍ）は、Ｕ字状部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ）と、当該Ｕ字状部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ）の一端（３３ｊ側）に連設された自由端部（３３ｋ，３３ｍ）とで構成されている。そして、自由端部（３３ｋ，３３ｍ）の円弧状突起部３３ｋに、ソケット側電源用端子３３の接点部Ｒ４が設けられている。 Further, in the present embodiment, the spring portion (33e, 33f, 33g, 33h, 33i, 33j, 33k, 33m) is formed of a U-shaped portion (33e, 33f, 33g, 33h, 33i, 33j) and the U shape. It is comprised with the free end part (33k, 33m) provided in a row by the one end (33j side) of a shape part (33e, 33f, 33g, 33h, 33i, 33j). A contact portion R4 of the socket-side power supply terminal 33 is provided on the arc-shaped protruding portion 33k of the free end portion (33k, 33m).
　このように、ソケット側電源用端子３３は、Ｕ字状部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ）を有しており、当該Ｕ字状部（３３ｅ，３３ｆ，３３ｇ，３３ｈ，３３ｉ，３３ｊ）の一端（３３ｊ側）には、接点部Ｒ４が設けられる自由端部（３３ｋ，３３ｍ）が連設されている。 As described above, 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) is connected to one end (33j side) of a free end portion (33k, 33m) provided with a contact portion R4.
　さらに、本実施形態では、互いに接触するソケット側電源用端子３３の接点部Ｒ４およびヘッダ側電源用端子２３の接点部Ｒ４のうちいずれか一方の接点部であるヘッダ側電源用端子２３の接点部Ｒ４に、凹部２３ｂが形成されている。そして、他方の接点部であるソケット側電源用端子３３の接点部Ｒ４が、凹部２３ｂにおけるソケットハウジング３１の長手方向Ｘ両端部で接触するようにしている。 Further, in the present embodiment, the contact portion of the header-side power supply terminal 23 that is one of 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 that are in contact with each other. A recess 23b is formed in R4. The contact portion R4 of the socket-side power supply terminal 33, which is the other contact portion, is in contact at both ends in the longitudinal direction X of the socket housing 31 in the recess 23b.
　具体的には、ソケット側電源用端子３３の円弧状突起部３３ｋが凹部２３ｂに嵌まり込む際に、円弧状突起部３３ｋの先端面３３ｖと傾斜面３３ｗとの境界部分が傾斜面２３ｈにそれぞれ接触している。このように、本実施形態では、ソケット側電源用端子３３の接点部Ｒ４が、ヘッダ側電源用端子２３の接点部Ｒ４に２点で接触するようにしている。 Specifically, when the arc-shaped protrusion 33k of the socket-side power terminal 33 is fitted into the recess 23b, the boundary between the tip surface 33v and the inclined surface 33w of the arc-shaped protrusion 33k is formed on the inclined surface 23h. In contact. As described above, in this embodiment, the contact portion R4 of the socket-side power supply terminal 33 contacts the contact portion R4 of the header-side power supply terminal 23 at two points.
　なお、ばね部の弾性変形に起因して、接点部Ｒ３、接点部Ｒ４以外に、平坦部３３ｇと第１の斜め部３３ｈとの境界部が第１の回路基板６０に接点部Ｒ５で接触する場合もある。 In addition, 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 portion R3 and the contact portion R4. In some cases.
　このように、本実施形態のヘッダ側電源用端子２３とソケット側電源用端子３３とは、幅方向Ｙに離間した複数の接点で接している。しかしながら、本開示のヘッダ側電源用端子とソケット側電源用端子とは、例えば、ヘッダ側電源用端子の内側面とソケット側電源用端子の対向部との１接点のみで接触するものであってもよい。 Thus, the header-side power supply terminal 23 and the socket-side power supply terminal 33 of this embodiment are in contact with a plurality of contacts spaced apart in the width direction Y. However, the header-side power supply terminal and the socket-side power supply terminal of the present disclosure are, for example, in contact with only one contact point between the inner side surface of the header-side power supply terminal and the facing portion of the socket-side power supply terminal. Also good.

　さらに、立下り部３５ｄの幅方向Ｙの両端側の先端は、ＸＹ平面（第１の回路基板６０の主表面Ｍ）に沿って延在するように屈曲させた形状をしている。すなわち、立下り部３５ｄの幅方向Ｙの両端側の先端をＸ方向外側に突出させることで、第１の固定部３５ｅを立下り部３５ｄの幅方向Ｙの両端側に形成している。一方、立下り部３５ｄの幅方向Ｙの両端側の先端は屈曲された形状をしておらず、かかる部位に形成された第１の固定部３５ｅは、先端を第１の回路基板６０の主表面Ｍに突き当てるようにした状態で、第１の回路基板６０の回路パターンに固定される。 Furthermore, the leading ends on both end sides in the width direction Y of the falling portion 35d are bent so as to extend along the XY plane (the main surface M of the first circuit board 60). That is, the first fixing portion 35e is formed on both ends of the falling portion 35d in the width direction Y by projecting the tips on both ends in the width direction Y of the falling portion 35d outward in the X direction.

It is fixed to the circuit pattern of the first circuit board 60 in a state where it abuts against the surface M.
　このように、幅広の立下り部３５ｄの両端および中央に第１の固定部３５ｅを設けることで、ソケット側保持金具３４をより強固に第１の回路基板６０に固定することができるようになる。 Thus, by providing the first fixing portions 35e at both ends and the center of the wide falling portion 35d, the socket-side holding metal fitting 34 can be more firmly fixed to the first circuit board 60. .

The thing formed so that it might become symmetrical (connector without polarity) was illustrated.
　しかしながら、極性を有するコネクタ（１８０度回転させた際に、同一の形状とならないようにしたコネクタ）に本開示を適用することも可能である。 However, it is also possible to apply the present disclosure to a connector having polarity (a connector that does not have the same shape when rotated 180 degrees).
　また、ヘッダ２０とソケット３０とを嵌合させた状態で、ヘッダ側保持金具とソケット側保持金具とが係合する構成とすることも可能である。 It is also possible to adopt a configuration in which the header-side holding metal fitting and the socket-side holding metal fitting are engaged in a state where the header 20 and the socket 30 are fitted.
　また、第２のソケット端子および第２のヘッダ端子をグランド接続用の端子として用いることも可能である。こうすれば、グランド接続の信頼性をより向上させることができる。 Also, it is possible to use the second socket terminal and the second header terminal as ground connection terminals. In this way, the reliability of ground connection can be further improved.
　また、第２のソケット端子およびソケット側保持金具を別体に設けるとともに、第２のヘッダ端子および第２のソケット端子を電源用端子として用い、ソケット側保持金具およびヘッダ側保持金具をグランド接続用の端子として用いることも可能である。 In addition, the second socket terminal and the socket side holding metal fitting are provided separately, and the second header terminal and the second socket terminal are used as power supply terminals, and the socket side holding metal fitting and the header side holding metal fitting are for ground connection. It can also be used as a terminal.
　また、コネクタ接続体としてのヘッダに本開示を適用することも可能である。 Also, the present disclosure can be applied to a header as a connector connection body.
　また、ソケット側ハウジングやヘッダ側ハウジング、その他細部のスペック（形状、大きさ、レイアウト等）も適宜に変更可能である。 Also, the socket side housing, header side housing, and other detailed specifications (shape, size, layout, etc.) can be changed as appropriate.
