Moreover, the edge part by the side of the board | substrate part 46 in the 2nd latching | locking part 53 is the 2nd latching edge 55b orthogonal to the circumferential direction. Furthermore, the opening width of the opening 52 is substantially the same as the width of the contact portion 49 where the first locking portion 50 is not formed. The depth dimension of the recess 51 (the dimension in the circumferential direction from the extending edge of the second caulking piece 48 to the inner edge of the recess 51 on the substrate part 46 side) is substantially the same as the dimension in the circumferential direction of the contact portion 49. This is a dimension that is smaller than the width dimension (dimension in the circumferential direction) perpendicular to the projecting direction of the protrusion 35 described above.

  A rectangular first side plate 56 that extends upward at substantially right angles to the plate-like portion 43 is integrally formed at a position near the rear end portions on the left and right side edges of the plate-like portion 43. From the front end edge of the first side plate 56, a square second side plate 57 is integrally formed in a form extending in a folded manner rearwardly along the inner surface of the first side plate 56. The upper end edge of the second side plate 57 (the end edge opposite to the plate-like portion 43) has the same height as the upper end edge of the first side plate 56. The lower edge of the second side plate 57 is positioned higher than the lower edge of the first side plate 56 (plate portion 43). Further, the rear end edge of the second side plate 57 is located behind the rear end edge of the first side plate 56.

  From the rear end edge of the second side plate 57, a rear wall 58 having a rectangular shape is formed integrally with the second side plate 57 so as to extend along the rear end edge 43R of the plate-like portion 43 at a substantially right angle.

It arrange | positions with the form which continues in the front-back direction along a side edge. Therefore, when the rear wall 58 is formed on the subshell 32, neither the rear wall 58 nor the first side plate 56 and the second side plate 57 that support the rear wall 58 interfere with the caulking pieces 47 and 48 of the fixing portion 34. . Accordingly, the crimping pieces 47 and 48 are disposed in the vicinity of the rear end edge 43R of the plate-like portion 43, and between the rear end edge 43R of the plate-like portion 43 and the crimping pieces 47 and 48 (adhering portion 34). There is no big dead space. According to such a form of forming the rear wall 58, the longitudinal length of the shield shell 30 can be shortened, and as a result, the shield connector A can be reduced in size.

  Next, the assembly process of the shield connector A will be described. The rear end portion of the terminal fitting 21 is connected to each conductor 10 of the shield conductive path B, and then the front end portion of the conductor 10 is fitted into the groove portion of the holder 20 so that the conductor 10 and the terminal fitting 21 are positioned in the left-right direction.

Thereafter, the four terminal fittings 21 are simultaneously inserted into the inner housing 22, and then the inner housing 22 is inserted into the rectangular tube portion 33 of the main shell 31 from the rear. At this time, the subshell 32 is not assembled to the main shell 31, and there is no one that advances into the opening 36 at the rear end of the main shell 31, so that the inner housing 22 can be inserted without any trouble.

  Further, the inner housing 22 inserted into the rectangular tube portion 33 is secured by locking the lance 37 of the rectangular tube portion 33 in the locking hole 22a on the upper surface thereof, and the front edge of the rectangular tube portion 33 It stops in front by abutting against the stopper 38. In a state where the inner housing 22 is housed in the rectangular tube portion 33, the four conductors 10 led out from the inner housing 22 are surrounded by the rear end portion of the rectangular tube portion 33 and in the vicinity of the rear of the rectangular tube portion 33. The folded portion 11a of the shield member 11 and the sleeve 13 are disposed at the position. And the protrusion part 35 contacts or approaches the outer surface of the folding | returning part 11a of the shield member 11, and respond | corresponds.

  Thereafter, the subshell 32 is assembled to the main shell 31 so as to approach from below. In a state in which both shells 31 and 32 are assembled, the plate-like portion 43 of the subshell 32 closes the opening area of the cutout portion 39 of the main shell 31 and is in a form along the outer surface (lower surface) of the inner housing 22. Further, when the positioning protrusion 40 of the main shell 31 is fitted into the positioning portion 44 of the subshell 32, the relative movement of the shells 31 and 32 in the front-rear direction is restricted. Furthermore, the receiving part 41 is locked from the lower side with respect to the side edge part of the plate-like part 43, whereby the vertical separation of the shells 31 and 32 is restricted. Further, the contact piece 45 of the subshell 32 is elastically brought into contact with the outer surface of the main shell 31, and the shells 31 and 32 are connected so as to be electrically conductive.

  In the state where both shells 31 and 32 are assembled, the central region in the left-right direction of the open portion 36 at the rear end of the rectangular tube portion 33 is closed by the fixing portion 34 and the shield conductive path B. Of these, the left and right end regions that do not correspond to the fixing portion 34 and the shield conductive path B are closed by the rear wall 58 formed in the subshell 32. Thereby, high shielding performance at the rear end of the rectangular tube portion 33 is exhibited.

  Further, the substrate portion 46 of the fixing portion 34 is positioned so as to sandwich the portion of the shield conductive path B where the folded portion 11a of the shield member 11 is exposed vertically with the protruding portion 35, and both caulking pieces 47 and 48 are located so that the part which the folding | returning part 11a of the shield member 11 of the shield conductive path B is exposed may be pinched | interposed in the left-right direction.

  Thereafter, the fixing portion 34 and the shield member 11 are connected using an automatic crimping machine (not shown) provided with an anvil and a crimper. At the time of connection, the shield shell 30 and the shield conductive path B are set so that the substrate portion 46 of the fixing portion 34 is placed on the anvil. Then, the crimper descends and comes into contact with the tip (upper end) of the contact portion 49 of the first caulking piece 47 and the extended end edge of the second caulking piece 48. As the crimper descends, the crimping pieces 47 and 48 are deformed so as to fall inward, whereby the fixing portion 34 is reduced in diameter, and the folded portion 11a of the shield member 11 is wrapped.

  In this process, the inner peripheral surfaces of the two crimping pieces 47 and 48 are in contact with the left and right side edges of the protrusion 35. At this time, the extending edge of the first crimping piece 47 in the front-rear direction is used. Of these, the front and rear regions of the contact portion 49 and the front and rear regions of the second caulking piece 48 in the front-rear direction of the second caulking piece 48 abut on the side edge of the projecting portion 35. As a result, there is a concern that further normal deformation of the crimping pieces 47 and 48 may be hindered. However, in the present embodiment, the position of the first caulking piece 47 that first contacts the protrusion 35 is set in a region closer to the substrate part 46 than the extending edge of the first caulking piece 47, and The position of the second caulking piece 48 that first contacts the protrusion 35 is also set in the region closer to the substrate part 46 than the extended edge of the second caulking piece 48. Therefore, there is no possibility that the extended end edges of the crimping pieces 47 and 48 hit the side edges of the protrusions 35.

  After both the crimping pieces 47 and 48 are in contact with the projection 35 as described above, the two crimping pieces 47 and 48 continue to be further deformed so that the extended end edges thereof approach each other in the circumferential direction. At the end of deformation, the contact portion 49 enters the recess 51. Here, the contact portion 49 including the first locking portion 50 of the first caulking piece 47 is formed in a bent shape, and the first locking portion 50 is connected to the second locking portion 53 by this bent shape. Is displaced inward in the plate thickness direction (radial direction) from the locking position and is displaced in the opening width direction of the recess 51. Specifically, as shown in FIG. 5, the contact portion 49 is bent so as to be bent in a substantially arc shape when viewed in the circumferential direction, and thereby has a narrow form capable of passing through the opening 52 of the recess 51. Has been. Therefore, in the process in which both the crimps 47 and 48 are approaching in the circumferential direction, the contact portion 49 can enter the recess 51 without interfering with the second locking portion 53 as shown in FIG. .

  When the contact portion 49 enters the recess 51 and the first locking edge 50b reaches the position aligned with the second locking edge 55b in the circumferential direction or a position slightly behind the recess 51, the crimper Is stopped, and the deformation in the circumferential direction of both the caulking pieces 47 and 48 (that is, the diameter reduction deformation of the fixing portion 34) is completed. As a result, the folded portion 11a of the shield member 11 is strongly pressed against the outer periphery of the sleeve 13 by the base plate portion 46 and the both crimping pieces 47 and 48, and the shield member 11 and the subshell 32 (shield shell 30) can be electrically connected. And is fixed in a state in which detachment is restricted by friction.

  At this time, the protruding portion 35 of the main shell 31 is firmly sandwiched between the sleeve 13 together with the folded portion 11 a of the shield member 11 and the portion of the both crimping pieces 47, 48 excluding the contact portion 49. In other words, the projecting portion 35 is fixed to the fixing portion 34 together with the shield member 11. As a result, the protrusion 35 and the two crimping pieces 47 and 48 are fixed in a state where relative displacement is restricted, and the main shell 31 and the subshell 32 are held in an assembled state without rattling. Further, since the protruding portion 35 and the both crimping pieces 47 and 48 are fixed in a direct contact state, the main shell 31 and the subshell 32 are securely held in a state where they are connected so as to be electrically conductive.

  After both the crimping pieces 47 and 48 are deformed and fixed to the shield member 11, the outer peripheral surface of the contact portion 49 is pressed or pressed by a pressure member (not shown) incorporated in the crimper. At this time, the contact portion 49 including the first locking portion 50 is bent in such a manner that the central portion in the width direction (front-rear direction) perpendicular to the protruding direction of the contact portion 49 bulges toward the outer peripheral side. The hitting position or pressing position on the outer peripheral surface of the portion 49 is only one place in the center portion in the width direction, and the area along the circumferential direction of the center portion in the width direction is pressed or pressed. Further, as shown in FIGS. 8 and 9, the entire contact portion 49 including the first locking portion 50, the entire opening area of the recess 51, and both the front and rear arm portions 54 are protrusions on the inner peripheral side. The front end of the first locking portion 50 on the front side and the rear end of the first locking portion 50 on the rear side are in contact with the outer peripheral surface of the projection portion 35. Therefore, when the contact portion 49 is struck or pressed, the curved contact portion 49 is stretched by being sandwiched in the radial direction between the pressing member and the protrusion 35 (the curvature is reduced). To be deformed).

  In the process of deforming the curved contact portion 49 so as to extend, the contact portion 49 keeps a state in which it slides on the outer peripheral surface of the projection portion 35 at both the front and rear first locking portions 50, while maintaining a radial direction as a whole. Displacement inward (direction approaching the protrusion 35). Similarly, in the process in which the contact portion 49 is deformed, the front and rear first locking portions 50 keep a state of elastically pressing the protruding portion 35 toward the inner peripheral side due to the stress generated by the deformation in the contact portion 49. Therefore, even if the radial thickness of the folded portion 11 a sandwiched between the sleeve 13 and the protruding portion 35 varies, the folded portion 11 a is securely sandwiched between the projected portion 35 and the sleeve 13. The projecting portion 35 and the folded portion 11a are securely connected so as to be conductive, and the projecting portion 35 and the fixing portion 34 (contact portion 49) are reliably connected so as to be conductive. Therefore, the shield member 11, the main shell 31 (former base for forming the protrusion 35), and the subshell 32 (former base for forming the fixing portion 34) are connected to each other so as to be electrically connected to each other. Is done.

  The contact portion 49 deformed so as to be stretched has a shape in which the peripheral surface thereof is substantially flush with the peripheral surfaces of the arm portion 54 and the second caulking piece 48 (a shape in which the contact portion 49 is connected substantially smoothly in the circumferential direction) It becomes a shape along the outer peripheral surface of the portion 35 (a shape that makes contact with the outer peripheral surface of the protruding portion 35 in a generally surface contact state). Both the arm portions 54 and the second locking portion 53 are also in contact with the outer peripheral surface of the projection portion 35 in a face-to-face manner.

  When the contact portion 49 is extended, the first locking edge portion 50b of the first locking portion 50 on the front side (the left side in FIG. 8) is opposed to the second locking edge portion 55b of the second locking portion 53 on the front side. The first locking edge portion 50b of the first locking portion 50 on the rear side is the second locking edge portion 50b on the rear side. The second locking edge 55b of the locking portion 53 is locked so as to abut in the circumferential direction within the range of the plate thickness of the both locking portions 50, 53. Due to the locking action at the two front and rear positions, the two caulking pieces 47 and 48 are restricted from being separated in the circumferential direction (vertical direction in FIG. 8), and as a result, the expanding deformation of the fixing portion 34 is prevented.

  Further, when the contact portion 49 is extended, the first inclined edge portion 50a of the first locking portion 50 on the front side has a plate thickness of both the engaging portions 50 and 53 with respect to the inclined edge portion 55a on the front side of the recess 51. The first inclined edge portion 50a of the first locking portion 50 on the rear side is locked against the inclined edge portion 55a on the rear side of the concave portion. It is locked so as to abut in the circumferential direction within the range of the plate thickness of 53. Also by the locking action at the two front and rear positions, the two caulking pieces 47 and 48 are restricted from being spaced apart in the circumferential direction, and the fixing portion 34 is prevented from expanding and deforming.

  As described above, in the present embodiment, in the process in which the fixing portion 34 is fixed to the shield member 11 and the protruding portion 35, the contact portion 49 is inward in the radial direction while being in contact with the outer peripheral surface of the protruding portion 35. It is deformed while being displaced. Therefore, when the folded portion 11a of the shield member 11 is thin and its outer diameter dimension is smaller than the specified dimension, the projection 35 is pushed from the fixing portion 34 side and displaced radially inward, thereby causing the folded portion 11a to be displaced. Pressed against the outer peripheral surface. Thereby, the contact state between the inner surface of the projection part 35 and the outer peripheral surface of the folding | returning part 11a is stabilized. Further, the contact state between the inner peripheral surface of the fixing portion 34 and the outer surface of the projection portion 35 is maintained well. Therefore, the reliability of the shielding performance is excellent.

  Further, the contact portion 49 also has a function of regulating the separation of the pair of caulking pieces 47 and 48 in the circumferential direction by locking the first locking portion 50 to the second locking portion 53 of the recess 51. To do. Accordingly, the shape of the crimping pieces 47 and 48 can be simplified as compared with the case where the means for regulating the circumferential separation of the pair of crimping pieces 47 and 48 is formed separately from the contact portion 49. Is realized.

  Further, when the fixing portion 34 is fixed to the shield conductive path B, the pair of caulking pieces 47 and 48 are deformed so as to approach each other in the circumferential direction, so that the substrate portion 46 and the caulking pieces 47 and 48 are connected to the shield member 11. The contact portion 49 is caused to enter the recess 51. At this time, the contact portion 49 is formed in a bent shape so that the first locking portion 50 is displaced in the opening width direction of the recess 51 from the locking position of the recess 51 with the second locking portion 53. Therefore, when the contact portion 49 enters the recess 51, the first locking portion 50 of the contact portion 49 and the second locking portion 53 of the recess 51 do not interfere with each other. After the contact portion 49 enters the recess 51, if the contact portion 49 is deformed so that the bent portion extends, the first locking portion 50 of the contact portion 49 and the second locking portion 53 of the recess 51 are connected. It becomes a locked state.

  Further, when assembling, the inner housing 22 is inserted into the rectangular tube portion 33 from the rear, and then the main shell 31 and the subshell 32 are combined, and then the fixing portion 34 is connected to the projection portion 35 and the shield member. 11, the protrusion 35 is disposed at a position deviated in the vertical and horizontal directions with respect to the open portion 36 of the rear end surface of the rectangular tube portion 33, so that the inner housing 22 is inserted into the rectangular tube portion 33. Will not interfere with the work.

  Further, since both the first inclined edge portion 50a and the second inclined edge portion 55a are inclined with respect to the circumferential direction, the distance between the front and rear first inclined edge portions 50a as the contact portion 49 is extended. At the end of the process of gradually expanding, the wedge action occurs due to the contact between the first inclined edge 50a and the second inclined edge 55a. Due to this wedge action, the contact portion 49 is displaced in the direction of returning to the opening side with respect to the concave portion 51 (that is, both the caulking pieces 47 and 48 are separated in the circumferential direction and the diameter of the fixing portion 34 is increased). Is prevented. Further, since both the first inclined edge portion 50a and the second inclined edge portion 55a are close to the direction perpendicular to the axial direction, the pair of caulking pieces 47, The backlash in the axial direction of 48 is also reliably prevented.

  At the end of the process in which the contact portion 49 is extended, the caulking pieces 47 and 48 may be slightly displaced in the approaching direction due to the wedge action, so the extended edge of the contact portion 49 and the recess 51 It is preferable to leave a slight clearance between the rear edge and between the extended edge of the first caulking piece 47 and the extended edge of the second caulking piece 48.

  Further, as shown in FIGS. 8 and 9, in both the circumferential direction and the axial direction, the entire contact portion 49 including the first locking portion 50, the entire opening area of the recess 51, and the second locking portion 553 are provided. The entire both arm portions 54 are disposed within the formation range of the protruding portion 35. In this arrangement, in the process of fixing the fixing part 34 to the shield member 11 and the protrusion 35 and the process of deforming the contact part 49 so as to extend, the braided wire constituting the shield member 11 is connected to the first caulking piece 47 and the second caulking piece 47. A portion that may be caught between the caulking pieces 48 (that is, an approaching portion between the extending edge of the first caulking piece 47 and the extending end edge of the second caulking piece 48, and an extending edge of the contact portion 49 And a portion where the contact portion 49 enters in the opening 52, a first locking portion 50 (first locking edge portion 50b) and a second locking portion 53 in the recess 51. The (second locking edge portion 55b) approaches and locks, and the first inclined edge portion 50a and the second inclined edge portion 55a approach and lock each other). Is within the formation range of the portion 35, and is the shield member 11 (braided wire) It has become isolated state. Therefore, when the fixing portion 34 and the shield member 11 are fixed, there is no possibility that the shield member (braided wire) bites between the first crimping piece 47 and the second crimping piece 48.

  Further, when the contact portion 49 is formed into a bent shape, the first caulking piece 47 is moved around the periphery in view of the contact portion 49 protruding from the extending end edge of the first caulking piece 47 in the circumferential direction. The shape is bent when viewed in the direction. Due to such a bent form, the contact portion 49 has a high rigidity even if its protruding dimension is large, so there is no possibility that the contact portion 49 will be illegally deformed due to interference of other members.

  In addition, when the contact portion is bent like an angle along the fold in the circumferential direction, when the contact portion is deformed so as to extend the bent portion, the fold portion remains in a ridgeline shape. There is a concern that poor contact with the protrusions on the inner peripheral surface of the contact portion may occur in the ridgeline portion or in the vicinity thereof. On the other hand, in this embodiment, since the contact part 49 was shape | molded in the curved form, when it deform | transforms so that a bending part may be extended, there is no possibility that a ridgeline-shaped crease may remain. Therefore, the contact reliability with the protrusion 35 on the inner peripheral surface of the contact portion 49 is excellent.
