The guide portion 28 of the second contact portion 21 is formed in a flat plate shape having a quadrangular guide hole 28a substantially at the center as shown in FIGS. 8 and 10 (a). Further, the guide hole 28 a is formed in a dimension that allows the first contact portion 11 of the first connection terminal 10 to be inserted.
第2接点部21の対向端部27は、図8から図10に示すように、一方端は軸線ALと平行な板状に形成され、他端はガイド部28、すなわち第1接点部11の挿入側に向かって広がる形状に形成されている。また、対向端部27は図9に示すように、弾性腕26の内周側の一方端に配設されている。
As shown in FIGS. 8 to 10, the opposing end portion 27 of the second contact portion 21 is formed in a plate shape whose one end is parallel to the axis AL, and the other end is the guide portion 28, that is, the first contact portion 11.

As shown in FIGS. 9 and 10B, the pair of elastic arms 26 of the second contact portion 21 is formed in a spiral shape extending so that the diameter decreases from the outer periphery toward the inner periphery with respect to the axis AL. ing. Further, as shown in FIG. 9, a guide portion 28 is connected to the end portion of the elastic arm 26.
弾性腕26は図9および図10(b)に示すように、対向端部27を挟んで互いに対向する外周側から、X方向と平行な板面が軸線ALを中心にしてガイド部28の板幅WB(図10参照)の範囲内で渦巻き状に巻かれた形状を有している。
As shown in FIGS. 9 and 10B, the elastic arm 26 is a plate of the guide portion 28 whose plate surface parallel to the X direction is centered on the axis AL from the outer peripheral side facing each other with the opposed end portion 27 interposed therebetween. It has a shape wound spirally within the range of the width WB (see FIG. 10).
前述するように弾性腕26は形成されているので、図9に示すX方向の寸法を短くしてばねスパンを長く形成することができる。このため、第1接点部11の接続に伴って所望の撓みを生じさせる必要がある第2接点部21をX方向に短く(小型)形成できる。
Since the elastic arm 26 is formed as described above, the spring span can be formed longer by shortening the dimension in the X direction shown in FIG. For this reason, the 2nd contact part 21 which needs to produce a desired bending with the connection of the 1st contact part 11 can be formed short (small) in the X direction.
ここで、端子接続構造100の第1接続端子10と第2接続端子20との接続について、第1接点部11と第2接点部21との接続構造を示す図4から図7までを用いて説明する。
Here, regarding the connection between the first connection terminal 10 and the second connection terminal 20 of the terminal connection structure 100, the connection structure between the first contact portion 11 and the second contact portion 21 will be described with reference to FIGS. explain.
第2接点部21の対向端部27は、図6および図7に示すように第1接点部11の側面部15と対向するように配設されている。
The opposing end portion 27 of the second contact portion 21 is disposed so as to face the side surface portion 15 of the first contact portion 11 as shown in FIGS. 6 and 7.
1対の弾性腕26は、図6および図7に示すように、対向端部27を介して接触部25が第1接点部11の側面部15に対して上下方向(Z方向)から圧接するように力を加えている。
As shown in FIGS. 6 and 7, in the pair of elastic arms 26, the contact portion 25 comes into pressure contact with the side surface portion 15 of the first contact portion 11 from the vertical direction (Z direction) via the opposed end portion 27. I am adding power.
第1接点部11の一方端は、図6に示すようにZ2方向から第2接点部21のガイド部28に向かって、軸線ALに沿うようにガイド孔28aに挿通され、設定位置(嵌合位置)まで挿通させて、第1接点部11と第2接点部21とが嵌合する。この際、対向端部27の他端側がガイド部28に向かって広がる形状であるため、図4から図7までに示すように、第1接点部11の一方端が1対の対向端部27間へ確実にガイドされることで、第1接続端子10が第2接続端子20へ挿通し易くなる。
One end of the first contact portion 11 is inserted into the guide hole 28a along the axis AL from the Z2 direction toward the guide portion 28 of the second contact portion 21 as shown in FIG. The first contact portion 11 and the second contact portion 21 are fitted to each other. At this time, since the other end side of the opposed end portion 27 is widened toward the guide portion 28, one end of the first contact portion 11 is a pair of opposed end portions 27 as shown in FIGS. 4 to 7. The first connection terminal 10 can be easily inserted into the second connection terminal 20 by being reliably guided in between.
第1接点部11と第2接点部21とが上記のように嵌合することで、図6に示すように、第2接点部21の接触部25がZ方向から第1接点部11の側面部15と接触することで、第1接点部11(第1接続端子10)と第2接点部21(第2接続端子20)とが電気的に導通する。
By fitting the first contact portion 11 and the second contact portion 21 as described above, as shown in FIG. 6, the contact portion 25 of the second contact portion 21 faces the side surface of the first contact portion 11 from the Z direction. By making contact with the part 15, the first contact part 11 (first connection terminal 10) and the second contact part 21 (second connection terminal 20) are electrically connected.
上記のように構成された端子接続構造100は、1度接続されれば、第1接点部11および第2接点部21に振動や衝撃が加わって、側面部15と接触部25との接触位置が位置ズレしても、弾性腕26のばねスパンが長く、且つ、ばね性が高いので、元の接触位置に復元する復元力が高くなる。このため、端子接続構造100は電気的な接続信頼性が高い。
When the terminal connection structure 100 configured as described above is connected once, vibration and impact are applied to the first contact portion 11 and the second contact portion 21, and the contact position between the side surface portion 15 and the contact portion 25. Even if the position shifts, since the spring span of the elastic arm 26 is long and the spring property is high, the restoring force to restore the original contact position becomes high. For this reason, the terminal connection structure 100 has high electrical connection reliability.
次に、本発明の端子接続構造100をツイストペアケーブル用の接続コネクタとして用いた例を図11に示す。図11におけるケーブルCA、第1接続端子10、第2接続端子20は、前記の第1実施形態と同一であり、その詳細は省略する。
Next, an example in which the terminal connection structure 100 of the present invention is used as a connection connector for a twisted pair cable is shown in FIG. The cable CA, the first connection terminal 10, and the second connection terminal 20 in FIG. 11 are the same as those in the first embodiment, and the details thereof are omitted.
第3接続端子110は基本的には第1接続端子10と同等の構造の雄型の接続端子であり、第1接続端子10の下側(Z2方向)に交差するようにして形成され、先端部を上側(Z1方向)に屈曲して、先端部が第1接続端子10の先端部とほぼ同じ高さに揃えられている。
The third connection terminal 110 is basically a male connection terminal having a structure equivalent to that of the first connection terminal 10 and is formed so as to intersect the lower side (Z2 direction) of the first connection terminal 10. The tip is bent to the upper side (Z1 direction) and the tip is aligned with the tip of the first connection terminal 10 at substantially the same height.
第4接続端子120は基本的には第2接続端子20と同等の構造の雌型の接続端子であり、第2接続端子20の上側(Z1方向)に交差するよう形成されてケーブルCA2に接続される。
The fourth connection terminal 120 is basically a female connection terminal having a structure equivalent to that of the second connection terminal 20, and is formed so as to intersect with the upper side (Z1 direction) of the second connection terminal 20, and is connected to the cable CA2. Is done.
1対のケーブルCA、CA2でツイストペアケーブルを構成する。よく知られているようにツイストペアケーブルにおいては、各ケーブルに流れる電流によって発生する磁界の向きがツイストピッチ毎に逆向きになるため、隣り合う磁界がキャンセルされケーブル(CA、CA2)から発生する放射ノイズを抑えることができる。このため、図11で示す例の場合、端子接続構造100のX1方向における寸法を短くすることができ、ツイストペアケーブルのツイストピッチに近づけることができるので効果的に隣り合う磁界をキャンセルすることが可能となり放射ノイズを効果的に抑えることができる。
A twisted pair cable is composed of a pair of cables CA and CA2. As is well known, in a twisted pair cable, the direction of the magnetic field generated by the current flowing in each cable is reversed every twist pitch, so that adjacent magnetic fields are canceled and radiation generated from the cables (CA, CA2). Noise can be suppressed. For this reason, in the case of the example shown in FIG. 11, the dimension in the X1 direction of the terminal connection structure 100 can be shortened, and it can be brought close to the twist pitch of the twisted pair cable, so that adjacent magnetic fields can be canceled effectively. Therefore, radiation noise can be effectively suppressed.
以上のように構成された本発明の第1実施形態の端子接続構造100における効果について、以下にまとめて説明する。
The effects of the terminal connection structure 100 according to the first embodiment of the present invention configured as described above will be collectively described below.
本発明の端子接続構造100は、第2接続端子20の第2接点部21が第1接点部11の側面部15と接触するように渦巻き状の弾性腕26を備えているので、ばねスパンを確保でき、且つ、第1接続端子10と接続される端子接続構造100の寸法を抑えられる。このため、小型で電気的な接続信頼性が高い端子接続構造100を提供することができる。
Since the terminal connection structure 100 of the present invention includes the spiral elastic arm 26 so that the second contact portion 21 of the second connection terminal 20 contacts the side surface portion 15 of the first contact portion 11, the spring span is reduced. The size of the terminal connection structure 100 that can be secured and connected to the first connection terminal 10 can be suppressed. For this reason, the terminal connection structure 100 which is small and has high electrical connection reliability can be provided.
また、板幅WBの範囲内で渦巻き状に巻かれているため、端子接続構造100の寸法をより抑えることができる。
Moreover, since the coil is wound in a spiral shape within the range of the plate width WB, the dimensions of the terminal connection structure 100 can be further suppressed.
また、端子接続構造100のX1方向における寸法を短くすることができ、ツイストペアケーブルのツイストピッチに近づけることができるので効果的に隣り合う磁界をキャンセルすることが可能となり放射ノイズを効果的に抑えることができる。
Moreover, since the dimension in the X1 direction of the terminal connection structure 100 can be shortened and can be brought close to the twist pitch of the twisted pair cable, it is possible to effectively cancel adjacent magnetic fields and effectively suppress radiation noise. Can do.
