A first embodiment of the present invention will be described below with reference to FIGS. The shield connector A of the present embodiment includes a housing 10, a shield shell 30, a terminal fitting 40, and a connection member 50.

ハウジング１０は合成樹脂製であって、ブロック状をなすインナハウジング１１と、インナハウジング１１の後端側部分を包囲するとともにインナハウジング１１よりも後方へ延出する略角筒状のアウタハウジング１２と、アウタハウジング１２からインナハウジング１１を包囲するように前方へ延出する略角筒状の筒状嵌合部１３とを一体形成したものである。インナハウジング１１とアウタハウジング１２とは、周方向に間隔を空けて配置した連結部１４によって連結されており、インナハウジング１１の外周とアウタハウジング１２の内周との隙間はシールドシェル３０の略前半部分を嵌入させるための略方形のスリット状をなす組付空間１５となっている。連結部１４は、組付空間１５のうち水平な上下両空間における左右両端部に配置されている。   The housing 10 is made of synthetic resin, and includes an inner housing 11 having a block shape, an outer housing 12 having a substantially rectangular tube shape that surrounds the rear end side portion of the inner housing 11 and extends rearward from the inner housing 11. A substantially square tubular fitting portion 13 that extends forward from the outer housing 12 so as to surround the inner housing 11 is integrally formed. The inner housing 11 and the outer housing 12 are connected by a connecting portion 14 that is spaced apart in the circumferential direction, and the gap between the outer periphery of the inner housing 11 and the inner periphery of the outer housing 12 is substantially the first half of the shield shell 30. An assembly space 15 is formed in a substantially rectangular slit shape for inserting the portion. The connection part 14 is arrange | positioned at the right-and-left both ends in horizontal both upper and lower space among the assembly | attachment space 15. FIG.

インナハウジング１１内には、横断面形状が略方形をなす左右一対のキャビティ１６が形成され、各キャビティ１６にはその下面壁に沿って前方へ延出するランス１７が形成されている。各キャビティ１６内には後方から端子金具４０が挿入されるようになっており、挿入された端子金具４０はランス１７の係止によって抜止めされる。アウタハウジング１２におけるインナハウジング１１よりも後方へ延出した筒状部の内部空間のうち、略前半部分は接続部材５０を収容するとともに接続部材５０とシールドシェル３０とを接続させるための収容空間１８となっており、略後半部分はゴム栓５５を収容するためのシール空間１９となっている。   A pair of left and right cavities 16 having a substantially square cross-sectional shape are formed in the inner housing 11, and lances 17 extending forward along the lower wall are formed in each cavity 16. A terminal fitting 40 is inserted into each cavity 16 from the rear, and the inserted terminal fitting 40 is prevented from being pulled out by locking the lance 17. Of the internal space of the tubular portion of the outer housing 12 that extends rearward from the inner housing 11, the substantially first half portion accommodates the connection member 50 and also accommodates the connection member 50 and the shield shell 30. The substantially latter half is a seal space 19 for accommodating the rubber stopper 55.

アウタハウジング１２の内壁には、４つの撓み部２０が形成されている。撓み部２０は、前後方向においては収容空間１８の後端部に位置し、収容空間１８の上面壁と下面壁に夫々２つずつ設けられている。上面壁の２つの撓み部２０は、左右方向において一対の連結部１４の間に挟まるように且つ連結部１４に隣接するように配置されている。下面壁の２つの撓み部２０も、同様に、一対の連結部１４の間に挟まるように且つ連結部１４に隣接するように配置されている。   Four flexible portions 20 are formed on the inner wall of the outer housing 12. The bending portion 20 is located at the rear end portion of the accommodation space 18 in the front-rear direction, and is provided on each of the upper surface wall and the lower surface wall of the accommodation space 18. The two bent portions 20 of the upper surface wall are disposed so as to be sandwiched between the pair of connecting portions 14 in the left-right direction and adjacent to the connecting portions 14. Similarly, the two bent portions 20 of the lower wall are arranged so as to be sandwiched between the pair of connecting portions 14 and adjacent to the connecting portions 14.

上側の撓み部２０は、板面を略水平に向けた板片状をなすとともに斜め下後方へ片持ち状に延出する形態であって、前端を略支点として上下方向（後述する接続部材５０に対して接近・離間する方向）に弾性撓みし得るようになっている。上側の撓み部２０の延出端部は、段差状に低くなった矯正部２１となっている。撓み部２０のうち矯正部２１よりも前方の領域の上方には、撓み部２０の上方への弾性撓みを許容する撓み空間２２が形成され、矯正部２１の上方には、撓み部２０の上方への弾性撓みを許容するとともにシールドシェル３０の係止片３５を収容するための係止空間２３が形成されいる。係止空間２３の上下寸法は、係止片３５の板厚よりも大きい寸法となっている。また、撓み部２０は、収容空間１８の上面から下方へ突出されている。なお、下側の撓み部２０は、上側の撓み部２０と上下対称であるので、説明は省略する。   The upper deflecting portion 20 has a plate-like shape with the plate surface oriented substantially horizontally and extends in a cantilevered manner obliquely downward and rearward, and has a front end as a substantially fulcrum and a vertical direction (a connecting member 50 described later). It can be elastically bent in the direction of approaching / separating with respect to. The extended end portion of the upper deflection portion 20 is a correction portion 21 that is lowered in a step shape. A bending space 22 that allows elastic bending upward of the bending portion 20 is formed above a region in front of the correction portion 21 in the bending portion 20, and above the bending portion 20 above the correction portion 21. A locking space 23 is formed to allow elastic locking of the shield shell 30 and to accommodate the locking piece 35 of the shield shell 30. The vertical dimension of the locking space 23 is larger than the plate thickness of the locking piece 35. Further, the bending portion 20 protrudes downward from the upper surface of the accommodation space 18. The lower flexure 20 is vertically symmetric with the upper flexure 20 and will not be described.

シールドシェル３０は、金属製の板材を曲げ加工したものであり、全体として概ね角筒状をなしている。シールドシェル３０の略前半部分は後方から組付空間１５内に嵌入され、シールドシェル３０の抜止片３１の係止によって後方への抜止めがなされ、ハウジング１０に対して軸線方向（前後方向）、左右方向（幅方向）、上下方向及び周方向（軸線周りの回転方向）のいずれの方向においても移動を規制された状態で組み付けられている。シールドシェル３０の略後半部分は収容空間１８の内周面に沿って配置されている。   The shield shell 30 is formed by bending a metal plate material, and has a generally rectangular tube shape as a whole. A substantially front half portion of the shield shell 30 is fitted into the assembly space 15 from the rear, and is prevented from being pulled out backward by the locking of the retaining piece 31 of the shield shell 30. They are assembled in a state where movement is restricted in any of the left-right direction (width direction), the up-down direction, and the circumferential direction (rotation direction around the axis). A substantially second half portion of the shield shell 30 is disposed along the inner peripheral surface of the accommodation space 18.

シールドシェル３０の後端部には、４片の接触片３２が４つの矯正部２１（撓み部２０）と対応するように配置されて形成されている。上側の２つの接触片３２は、夫々、シールドシェル３０の後端縁から前方へ左右一対のスリットを切欠することにより、後方へ片持ち状に延出する形態に形成されている。接触片３２のうち、前端から前後方向中央よりも少し前方の位置に至る部分は、後方に向かって下り勾配となった傾斜部３３となっている。また、傾斜部３３の後端からは水平部３４が延出している。さら、水平部３４の後端には、上側へ折り返されて前方へ突出する係止片３５が形成されている。水平部３４と係止片３５との間隔は、矯正部２１の厚さ寸法と同じかそれよりも少し大きい寸法となっている。   At the rear end of the shield shell 30, four contact pieces 32 are formed so as to correspond to the four correction portions 21 (flexure portions 20). The upper two contact pieces 32 are each formed in a form that cantilevered backward by cutting a pair of left and right slits forward from the rear end edge of the shield shell 30. A portion of the contact piece 32 that extends from the front end to a position slightly ahead of the center in the front-rear direction is an inclined portion 33 that has a downward slope toward the rear. Further, a horizontal portion 34 extends from the rear end of the inclined portion 33. Further, a locking piece 35 is formed at the rear end of the horizontal portion 34 so as to be folded upward and protrude forward. The distance between the horizontal portion 34 and the locking piece 35 is the same as or slightly larger than the thickness of the correction portion 21.

シールドシェル３０をハウジング１０に組み付けた状態では、水平部３４の後端部が矯正部２１の内面（下面）に対して下から弾性的に当接し、これによって接触片３２が上下方向に位置決めされるとともに、所定の形状に保たれる。また、係止片３５が係止空間２３内に対して後方から進入するように収容されるとともに、矯正部２１が水平部３４の後端部と係止片３５との間で上下に挟まれるように位置する。また、シールドシェル３０と接続部材５０が非接続の状態では、係止片３５の上面（外面）と係止空間２３の内面との間には、撓み部２０の上方への変位を許容する空間が確保されている。また、水平部３４の前端は撓み部２０の前端よりも前方に位置し、撓み部２０の下面が水平部３４に対して前方に向かって上り勾配に傾斜しているので、撓み部２０の下面（内面）と接触片３２（水平部３４）の上面（外面）との間には、スペースＳが空いている。換言すると、接触片３２（傾斜部３３）の前端は収容空間１８の内面（ハウジング１０）に接触し、接触片３２（水平部３４）の後端は矯正部２１の内面（ハウジング１０）に接触しているのであるが、それ以外の領域、即ち、接触片３２における基端部（前端部）と延出端部（後端部）との間の領域はハウジング１０から離間している。かかる接触片３２は、その前端を略支点として上下方向へ弾性撓みし得るようになっている。なお、下側の接触片３２及び下側の接触片３２と下側の撓み部２０との当接・係止形態は、上側の接触片３２と上下対称であるので、説明は省略する。   In a state where the shield shell 30 is assembled to the housing 10, the rear end portion of the horizontal portion 34 elastically contacts the inner surface (lower surface) of the correction portion 21 from below, and thereby the contact piece 32 is positioned in the vertical direction. And maintained in a predetermined shape. In addition, the locking piece 35 is accommodated so as to enter the locking space 23 from behind, and the correction portion 21 is sandwiched between the rear end portion of the horizontal portion 34 and the locking piece 35 in the vertical direction. Is located. Further, in a state where the shield shell 30 and the connection member 50 are not connected, a space that allows an upward displacement of the bending portion 20 between the upper surface (outer surface) of the locking piece 35 and the inner surface of the locking space 23. Is secured. Further, the front end of the horizontal portion 34 is positioned forward of the front end of the bending portion 20, and the lower surface of the bending portion 20 is inclined upward with respect to the horizontal portion 34. A space S is vacant between the (inner surface) and the upper surface (outer surface) of the contact piece 32 (horizontal portion 34). In other words, the front end of the contact piece 32 (inclined portion 33) contacts the inner surface (housing 10) of the accommodation space 18, and the rear end of the contact piece 32 (horizontal portion 34) contacts the inner surface (housing 10) of the correction portion 21. However, the other region, that is, the region between the base end portion (front end portion) and the extended end portion (rear end portion) of the contact piece 32 is separated from the housing 10. The contact piece 32 can be elastically bent in the vertical direction with its front end as a substantially fulcrum. Note that the lower contact piece 32 and the contact / locking form of the lower contact piece 32 and the lower flexure 20 are symmetrical with the upper contact piece 32, and the description thereof will be omitted.

端子金具４０は、全体として前後方向に細長く、略前半部分は角筒部４１となっており、略後半部分は電線圧着部４２となっていて、この電線圧着部４２にはシールド電線４５の前端部が接続されている。シールド電線４５は、導体４６を合成樹脂製のコア４７で包囲し、コア４７の外周に筒状の編組線４８を被せ、編組線４８を合成樹脂製のシース４９で包囲した周知構造の導電体である。シールド電線４５の前端部においては、露出状態とされた導体４６が電線圧着部４２のワイヤバレルにカシメ付けられているとともに、コア４７の前端部が電線圧着部４２のインシュレーションバレルにカシメ付けられている。電線圧着部４２よりも後方においては、シース４９を除去して露出させた編組線４８が、後方へ折り返されてシース４９の外周面に重ねられており、この編組線４８の重ね合わせ部分には、接続部材５０が導通可能に且つ周方向への相対移動を規制された状態で固着されている。   The terminal fitting 40 is elongated in the front-rear direction as a whole, the substantially first half portion is a square tube portion 41, and the substantially second half portion is a wire crimping portion 42. The wire crimping portion 42 has a front end of a shielded wire 45. Are connected. The shielded electric wire 45 encloses a conductor 46 with a synthetic resin core 47, covers an outer periphery of the core 47 with a cylindrical braided wire 48, and surrounds the braided wire 48 with a synthetic resin sheath 49. It is. At the front end portion of the shielded electric wire 45, the exposed conductor 46 is crimped to the wire barrel of the wire crimping portion 42 and the front end portion of the core 47 is crimped to the insulation barrel of the wire crimping portion 42. ing. Behind the wire crimping portion 42, a braided wire 48 that is exposed by removing the sheath 49 is folded back and overlapped on the outer peripheral surface of the sheath 49. The connecting member 50 is fixed in a state where conduction is possible and relative movement in the circumferential direction is restricted.

接続部材５０は、略方形の金属板材を円筒形に曲げ加工したものであり、略前半部分は小径部５１となっており、略後半部分が大径部５２となっている。小径部５１は編組線４８に外嵌されてカシメ付けにより固着されている。大径部５２の外周面のうち、接続部材５０をハウジング１０に組み付けた状態において上端と下端に位置する領域は、接触片３２に接触される接触部５３となっている。   The connection member 50 is formed by bending a substantially square metal plate into a cylindrical shape, and the first half portion is a small diameter portion 51 and the second half portion is a large diameter portion 52. The small-diameter portion 51 is externally fitted to the braided wire 48 and fixed by caulking. Of the outer peripheral surface of the large-diameter portion 52, regions located at the upper end and the lower end when the connection member 50 is assembled to the housing 10 are contact portions 53 that are in contact with the contact pieces 32.

シールド電線４５に接続部材５０を固着した状態で、端子金具４０を後方からキャビティ１６内に挿入すると、接続部材５０の接触部５３がシールドシェル３０の接触片３２の内面に対して当接し、この当接により、シールドシェル３０と編組線４８が接続部材５０を介して導通可能に接続される。このとき、接触部５３は円弧面状に形成されているのに対し、接触片３２の水平部３４が平面状であることから、接触部５３は水平部３４に対して前後方向の線接触状に当接することになる。また、接触片３２と撓み部２０は、接続部材５０によって径方向に押されて外側へ弾性撓みする。   When the terminal fitting 40 is inserted into the cavity 16 from behind with the connection member 50 secured to the shielded electric wire 45, the contact portion 53 of the connection member 50 comes into contact with the inner surface of the contact piece 32 of the shield shell 30. By contact, the shield shell 30 and the braided wire 48 are connected via the connection member 50 so as to be conductive. At this time, the contact portion 53 is formed in an arcuate surface shape, whereas the horizontal portion 34 of the contact piece 32 is planar, so that the contact portion 53 has a line contact shape in the front-rear direction with respect to the horizontal portion 34. Will abut. Further, the contact piece 32 and the bending portion 20 are pushed in the radial direction by the connecting member 50 and elastically bent outward.

弾性撓みした状態では、係止片３５の外面と係止空間２３の内面との隙間が殆どなくなるので、それ以上の外側への弾性撓みが規制される。したがって、シールドシェル３０の接触片３２と接続部材５０の接触部５３が接触している状態においては、撓み部２０と接触片３２が外側へ逃げるように撓むことに起因して、接触片３２と接触部５３との接触が不安定になる、というおそれはない。
また、接触部５３の形成されている大径部５２は、上側の撓み部２０及び接触片３２と下側の撓み部２０及び接触片３２との間で弾性的に挟み付けられているので、大径部５２は上下方向において弾性的に位置決めされる。 In the elastically bent state, there is almost no gap between the outer surface of the locking piece 35 and the inner surface of the locking space 23, so that further elastic bending to the outside is restricted. Therefore, in the state where the contact piece 32 of the shield shell 30 and the contact portion 53 of the connecting member 50 are in contact, the contact piece 32 is caused by the bending portion 20 and the contact piece 32 being bent so as to escape outward. There is no fear that the contact with the contact portion 53 becomes unstable.
Moreover, since the large diameter part 52 in which the contact part 53 is formed is elastically sandwiched between the upper bending part 20 and the contact piece 32 and the lower bending part 20 and the contact piece 32, The large diameter portion 52 is elastically positioned in the vertical direction.

なお、端子金具４０と接続部材５０をハウジング１０に取り付けた後は、予めシールド電線４５に外嵌されているゴム栓５５を、前方へ移動させてハウジング１０内のシール空間１９内に嵌入するとともに、予めシールド電線４５に外嵌されているためのホルダ５６を、前方へ移動させてハウジング１０の後端部に固着しすることにより、ゴム栓５５を抜止めする。このゴム栓５５により、後方から収容空間１８内及びキャビティ１６内へ浸水することが防止される。
また、本実施形態のシールドコネクタＡと相手側コネクタＢとを嵌合した状態では、細長い相手側端子６０が端子金具４０の角筒部４１内に進入し、相手側端子６０と端子金具４０とが導通可能に接続される。 In addition, after attaching the terminal fitting 40 and the connection member 50 to the housing 10, the rubber plug 55 previously fitted to the shielded electric wire 45 is moved forward and fitted into the seal space 19 in the housing 10. The rubber plug 55 is prevented from being removed by moving the holder 56, which is externally fitted to the shield wire 45, to the front and fixing it to the rear end of the housing 10. The rubber plug 55 prevents water from entering the housing space 18 and the cavity 16 from behind.
Further, in a state where the shield connector A and the mating connector B of the present embodiment are fitted, the elongated mating terminal 60 enters the rectangular tube portion 41 of the terminal fitting 40, and the mating terminal 60, the terminal fitting 40, Are connected in a conductive manner.

上述のように本実施形態では、ハウジング１０に形成した矯正部２１に対し、シールドシェル３０の接触片３２を弾性的に当接させることにより、接触片３２の上下方向への変位を規制した。これにより、シールドシェル３０をハウジング１０に組み付ける前の状態において接触片３２の成形形状にばらつきがあっても、接触片３２の形状は矯正部２１への当接によって正規の形状に矯正される。このように接触片３２の形状を矯正したことにより、シールド電線４５側の接触部５３と接触片３２との間の接触圧が安定する。   As described above, in the present embodiment, the contact piece 32 of the shield shell 30 is elastically brought into contact with the correction portion 21 formed on the housing 10 to restrict the displacement of the contact piece 32 in the vertical direction. As a result, even if the molding shape of the contact piece 32 varies in a state before the shield shell 30 is assembled to the housing 10, the shape of the contact piece 32 is corrected to a normal shape by contacting the correction portion 21. By correcting the shape of the contact piece 32 in this manner, the contact pressure between the contact portion 53 on the shielded electric wire 45 side and the contact piece 32 is stabilized.

また、ハウジング１０に径方向に弾性撓み可能な撓み部２０を形成し、この撓み部２０に矯正部２１を形成したので、撓み部２０を弾性撓みさせつつ接触片３２を接触部５３と接触させることができる。つまり、撓み部２０の弾性復元力によって接触圧を確保することができる。   Further, since the bending portion 20 that can be elastically bent in the radial direction is formed in the housing 10 and the correction portion 21 is formed in the bending portion 20, the contact piece 32 is brought into contact with the contact portion 53 while the bending portion 20 is elastically bent. be able to. That is, the contact pressure can be ensured by the elastic restoring force of the bending portion 20.

また、接触片３２の延出端部（後端部）が矯正部２１に当接されており、接触片３２は、その基端部（前端部）と延出端部との間においてハウジング１０（収容空間１８の内面）から離間した形態となっているので、シールドシェル３０の組付けに伴って接触片３２が弾性変形するときに、その弾性変形がハウジング１０との干渉によって阻害されることがない。これにより、接触片３２は、接触部５３に対して良好な状態で弾性変形しつつ当接することができる。   In addition, the extended end portion (rear end portion) of the contact piece 32 is in contact with the correction portion 21, and the contact piece 32 is located between the base end portion (front end portion) and the extended end portion of the housing 10. Since the contact piece 32 is elastically deformed as the shield shell 30 is assembled, the elastic deformation is hindered by interference with the housing 10 because it is separated from the inner surface of the housing space 18. There is no. Thereby, the contact piece 32 can contact | abut to the contact part 53, elastically deforming in a favorable state.

また、シールド電線４５の編組線４８に接続部材５０を固着し、この接続部材５０の外周の接触部５３に接触片３２が当接させるようにしたので、シールドシェル３０とシールド電線４５の編組線４８との間の間隔が大きくても、接続部材５０を介在させることにより、接触片３２の形状をシールドシェル３０に沿ったシンプルな形態として、接触片３２の成形精度を向上させることが実現されている。   Further, since the connecting member 50 is fixed to the braided wire 48 of the shielded electric wire 45 and the contact piece 32 is brought into contact with the contact portion 53 on the outer periphery of the connecting member 50, the braided wire between the shield shell 30 and the shielded electric wire 45 is provided. Even when the distance between the contact piece 48 is large, by interposing the connection member 50, it is possible to make the shape of the contact piece 32 a simple form along the shield shell 30 and to improve the molding accuracy of the contact piece 32. ing.
