Abstract

This male terminal (220) has a spherical electrical-contact part (221) on the tip thereof, and this female terminal has a large number of contact spring parts (125) that are arranged in a radial fashion and thereby form an insertion hole (126) into which the aforementioned spherical electrical-contact part can be inserted. The contact spring parts hold the spherical electrical-contact part such that same can rotate, and second bend sections (125c) of the contact spring parts exert restraining forces on the spherical electrical-contact part so as to keep same in the insertion hole. The front end of a second connector housing that holds the male terminal is provided with a concave spherical surface (212a), the center of curvature of which coincides with the center of the spherical electrical-contact part. The front end of a first connector housing that holds the female terminal is provided with a convex spherical surface (112a) that slidably abuts against the aforementioned concave spherical surface.

　そして、各接触バネ片１２５は、雄端子２２０の球形電気接触部２２１が挿入穴１２６の受容空間部１２６ｃまで挿入された際に、球形電気接触部２２１に圧接した状態で球形電気接触部２２１を回転可能に保持し、且つ、窄まり形状部１２６ｂを形成する第２の屈曲部１２５ｃで、球形電気接触部２２１に対し弾性復元力を利用した抜け止め規制力を及ぼす構成になっている。 Then, each contact spring piece 125 pushes the spherical electrical contact portion 221 in a state of being pressed against the spherical electrical contact portion 221 when the spherical electrical contact portion 221 of the male terminal 220 is inserted to the receiving space portion 126c of the insertion hole 126. The second bent portion 125c that is rotatably held and forms the constricted shape portion 126b is configured to exert a retaining prevention force using an elastic restoring force on the spherical electric contact portion 221.

The contact wall 112 is integrally provided. When the spherical electrical contact portion 221 of the male terminal 220 is received in the receiving space portion 126 c of the insertion hole 126 of the female terminal 120, the front surface of the pressing wall 212 of the second connector housing 210 is formed on the front surface of the abutting wall 112. A convex spherical surface 112a that slidably contacts the concave spherical surface 212a is formed. In addition, a circular opening 113 through which the spherical electric contact portion 221 of the male terminal 220 is inserted is provided at the center of the contact wall 112 where the convex spherical surface 112a is formed.

FIG.
　次に作用を説明する。
　第１のコネクタ１００と第２のコネクタ２００を接続する場合、図２（ａ）に示すように、第２のコネクタハウジング２１０に収容保持された雄端子２２０の先端の球形電気接触部２２１を、第１のコネクタハウジング１１０の前端の当接壁１１２の開口１１３から、雌端子１２０の挿入穴１２６に挿入する。そうすると、まず、球形電気接触部２２１が、挿入穴１２６の入口部の拡開形状部１２６ａからその奥部の窄まり形状部１２６ｂを通過する過程で、挿入穴１２６を構成する接触バネ片１２５を半径方向外方に弾性変形させて、窄まり形状部１２６ｂを拡げる。 Next, the operation will be described.
When connecting the first connector 100 and the second connector 200, as shown in FIG. 2A, the spherical electrical contact portion 221 at the tip of the male terminal 220 accommodated and held in the second connector housing 210 is The first connector housing 110 is inserted into the insertion hole 126 of the female terminal 120 through the opening 113 of the abutting wall 112 at the front end. Then, first, in the process in which the spherical electric contact portion 221 passes from the expanded shape portion 126a at the entrance portion of the insertion hole 126 to the narrow shape portion 126b at the back thereof, the contact spring piece 125 constituting the insertion hole 126 is moved. The constricted portion 126b is expanded by elastically deforming outward in the radial direction.
　更に球形電気接触部２２１を押し込むと、球形電気接触部２２１が、接触バネ片１２５を半径方向外方に弾性変形させながら、拡がった窄まり形状部１２６ｂを抜けて、挿入穴１２６の最奥部の受容空間部１２６ｃに進入する。そうすると、接触バネ片１２５が内方に復元することで、窄まり形状部１２６ｂが元の形状に向けて閉じる。この段階で接触バネ片１２５は、弾性復元力で球形電気接触部２２１に圧接し、窄まり形状部１２６ｂを形成する接触バネ片１２５の第２の屈曲部１２５ｃが球形電気接触部２２１に抜け止め規制力を及ぼす。従って、球形電気接触部２２１は、多数の接触バネ片１２５によって、抜け止めされた状態で、受容空間部１２６ｃにおいて回動自在に保持される。 When the spherical electrical contact portion 221 is further pushed in, the spherical electrical contact portion 221 passes through the enlarged constricted shape portion 126b while elastically deforming the contact spring piece 125 radially outward, and the innermost portion of the insertion hole 126 is inserted. Enter the receiving space 126c. Then, when the contact spring piece 125 is restored inward, the constricted shape portion 126b is closed toward the original shape. At this stage, the contact spring piece 125 is pressed against the spherical electric contact portion 221 with an elastic restoring force, and the second bent portion 125c of the contact spring piece 125 forming the constricted shape portion 126b is prevented from coming off the spherical electric contact portion 221. Exert regulatory power. Accordingly, the spherical electric contact portion 221 is rotatably held in the receiving space portion 126c in a state of being prevented from being detached by the multiple contact spring pieces 125.
　また、このように受容空間部１２６ｃに球形電気接触部２２１が挿入された段階で、雌端子１２０を収容保持する第１のコネクタハウジング１１０の当接壁１１２の前面の凸球面１１２ａと、雄端子２２０を保持する第２のコネクタハウジング２１０の押圧壁２１２の前面の凹球面２１２ａとが球面方向に摺動自在に密接する。 In addition, when the spherical electrical contact portion 221 is inserted into the receiving space portion 126c in this way, the convex spherical surface 112a on the front surface of the contact wall 112 of the first connector housing 110 that receives and holds the female terminal 120, and the male terminal The concave spherical surface 212a on the front surface of the pressing wall 212 of the second connector housing 210 that holds 220 is in close contact with the spherical surface so as to be slidable.
　そして、このように球形電気接触部２２１が回転自在に保持され、第１のコネクタハウジング１１０の凸球面１１２ａと、第２のコネクタハウジング２１０の凹球面２１２ａとが球面方向に摺動自在に密接していることにより、第１のコネクタハウジング１１０と第２のコネクタハウジング２１０とを、雌端子１２０と雄端子２２０の接続を保ちながら、矢印Ｒ１、Ｒ２、Ｒ３、Ｒ４方向を含む３次元方向に自由に屈曲させることができる。 Thus, the spherical electric contact portion 221 is rotatably held, and the convex spherical surface 112a of the first connector housing 110 and the concave spherical surface 212a of the second connector housing 210 are slidably in close contact with each other in the spherical direction. As a result, the first connector housing 110 and the second connector housing 210 can be freely moved in a three-dimensional direction including the directions of arrows R1, R2, R3, and R4 while maintaining the connection between the female terminal 120 and the male terminal 220. Can be bent.
　この場合、図２（ｂ）に示すように、開口１１３の縁に、雄端子２２０のロッド２２２の基端に位置する防水リングＳ２が当たることで、第１のコネクタハウジング１１０に対する第２のコネクタハウジング２１０の可動範囲θが規制される。 In this case, as shown in FIG. 2 (b), the waterproof connector S2 positioned at the base end of the rod 222 of the male terminal 220 hits the edge of the opening 113, so that the second connector for the first connector housing 110 is obtained. The movable range θ of the housing 210 is restricted.
　また、このような接続状態のときに、防水リングＳ、Ｓ１、Ｓ２とＯリング１１５とがコネクタハウジング１１０、２１０の内部をシールするので、雌端子１２０と雄端子２２０の接続部分に対する防水・防塵性能を発揮することができる。 Further, in such a connected state, the waterproof rings S, S1, S2 and the O-ring 115 seal the inside of the connector housings 110 and 210. Therefore, the waterproof / dustproof structure for the connection portion between the female terminal 120 and the male terminal 220 is used. Performance can be demonstrated.
