Further, a folded receiving portion 41 is formed on the inner surface of the positioning projection 40.

  The subshell 32 is formed by bending a metal plate material 42 punched into a predetermined shape shown in FIG. The subshell 32 is formed by integrally forming a square plate-like portion 43 and a fixing portion 34 extending rearward from the rear end edge 43R of the plate-like portion 43. Positioning portions 44 are formed in the left and right side edges of the plate-like portion 43 so as to be shallowly recessed. A pair of left and right contact pieces 45 are formed on the front end edge of the plate-like portion 43 so as to protrude obliquely upward.

  The fixed portion 34 is continuous with the rear end edge 43 </ b> R of the plate-like portion 43. The fixing portion 34 has an open barrel shape in which a pair of plate-like caulking pieces 47 and 48 are extended in the circumferential direction from the left and right side edges of the substrate portion 46 in the front-rear direction (axial direction of the shield conductive path B). There is no. The fixed portion 34 protrudes rearward from the rear end edge 43R of the plate-like portion 43 in a form in which the front end of the substrate portion 46 is connected to the rear end edge 43R of the plate-like portion 43. In the unfolded state before the metal plate material 42 is bent, the pair of caulking pieces 47 and 48 extend in the left-right direction along the rear end edge 43R of the plate-like portion 43 as shown in FIG. Has been placed. Further, in a state after the metal plate material 42 is bent and before the fixing portion 34 is fixed to the shield member 11, as shown in FIGS. 2 and 4, the pair of caulking pieces 47 and 48 are formed on the substrate portion 46. The direction is extended obliquely upward.

  Of the pair of caulking pieces, the first caulking piece 47 is formed with a convex portion 49 that protrudes in the circumferential direction from the extending end edge in the front-rear direction. The convex part 49 is arrange | positioned in the center position in the front-back direction among extension edges. Further, the convex portion 49 is formed with a pair of first locking portions 50 that protrude from both front and rear side edges along the protruding direction (circumferential direction).

  As shown in FIGS. 7 and 8, in the unfolded state before the metal plate material 42 is bent and in the state where the fixing portion 34 is fixed to the shield member 11, the first locking portion of the protruding end portion of the convex portion 49 is used. The region where 50 is formed has a trapezoidal shape that becomes narrower toward the protruding end side.

  In a state after the metal plate material 42 is bent and before the fixing portion 34 is fixed to the shield member 11, as shown in FIGS. 4 and 5, the convex portion 49 and the first engagement portion of the first caulking piece 47. The stopper 50 is bent and formed into a shape that is curved in a substantially arc shape when viewed in the circumferential direction. The curved form of the convex portion 49 and the first locking portion 50 is such that the central portion in the width direction orthogonal to the protruding direction (that is, the circumferential direction) of the convex portion 49 from the first caulking piece 47 swells to the outer peripheral side. It is a form. By bending the convex portion 49 and the first locking portion 50 in this way, as shown in FIG. 9, the convex portion 49 including the first locking portion 50 has a width dimension orthogonal to the circumferential direction. The width is smaller than the opening width of the opening 52 of the recess 51 described later.

  Of the pair of caulking pieces 47, 48, the second caulking piece 48 is formed with a recess 51 having an opening at the extending end edge in the front-rear direction. In the opening 52 of the recess 51, a pair of front and rear second locking portions 53 are formed so as to protrude along the extending edge of the second crimping piece 48. The front second locking portion 53 protrudes rearward from the front edge of the opening 52, and the rear second locking portion 53 protrudes forward from the rear edge of the opening 52, Due to the pair of second locking portions 53, the recess 51 has a form in which the opening width of the opening 52 is narrowed. The inner edge (the side facing the recess 51) of the second locking portion 53 is inclined with respect to the circumferential direction.

  Moreover, the part which pinches | concludes the recessed part 51 among the 2nd crimping pieces 48 becomes a pair of arm part 54, The above-mentioned 2nd latching | locking part 53 becomes a form protruded from the front-end | tip of the arm part 54. As shown in FIG. . Then, a pair of front and rear in a form in which the front end portion and the rear end portion are obliquely projected toward the second locking portion 53 side at the rear end edge (the edge portion on the opposite side of the opening portion 52 in the circumferential direction) of the concave portion 51. The reinforcing portion 55 is formed. By this reinforcing portion 55, the base end portion of the arm portion 54 is reinforced by expanding the width dimension. Due to this reinforcement, the arm portion 54 is less likely to be deformed to increase the opening width of the opening 52 of the recess 51.

  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. Has been. The rear wall 58 is disposed at substantially the same position as the rear end edge 43R of the plate-like portion 43 in the front-rear direction. The upper end edge of the rear wall 58 (the end edge opposite to the plate-like portion 43) has the same height as the upper end edges of the first side plate 56 and the second side plate 57. The lower end edge of the rear wall 58 (the end edge on the plate-like portion 43 side) has the same height as the lower end edge of the second side plate 57.

  In the unfolded state before the metal plate material 42 is bent, as shown in FIG. 7, the first side plate 56 is positioned in the vicinity of the side of the plate-like portion 43, and the second side plate 57 is positioned in front of the first side plate 56. The rear wall 58 is positioned in front of the second side plate 57. That is, the first side plate 56, the second side plate 57, and the rear wall 58 are located in front of the rear end edge 43 </ b> R of the plate-like portion 43 (in the direction opposite to the fixing portion 34 in the front-rear direction). 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. To do. 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 adhering portion 34 and the shield member 11 are connected using an automatic crimping machine (not shown) having 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 leading end (upper end) of the convex 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 and wrap around the folded portion 11 a of the shield member 11.

  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 convex portion 49, and the rear edge in the front-rear direction closest to the substrate portion 46 among the opening edges of the concave portion 51 of the second caulking piece 48 hit the side edge of the projection portion 35, and 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 where the second caulking piece 48 first comes into contact with the protrusion 35 is also set in the region closer to the substrate portion 46 than the back edge of the recess 51. 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 protrusion 35 as described above, the two crimping pieces 47 and 48 are deformed so that their extended end edges are close to each other in the circumferential direction, and the end of the deformation Then, the convex portion 49 enters the concave portion 51. Here, the convex portion 49 of the first caulking piece 47 and the first locking portion 50 are formed in a bent shape, and the first locking portion 50 and the second locking portion 53 are thus bent. While being displaced inward in the plate thickness direction (radial direction) from the locking position, the position is displaced in the opening width direction of the recess 51. Specifically, as shown in FIG. 5, the convex portion 49 and the first locking portion 50 are bent so as to be curved in a substantially arc shape when viewed in the circumferential direction, thereby passing through the opening 52 of the concave portion 51. The narrow form is possible. Therefore, in the process in which both the caulking pieces 47 and 48 approach in the circumferential direction, the convex portion 49 and the first locking portion 50 do not interfere with the second locking portion 53 without interfering with the concave portion 51 as shown in FIG. You can enter inside.

  When the convex portion 49 enters the concave portion 51, the lowering of the crimper stops, and the deformation of both the crimping pieces 47 and 48 in the circumferential direction 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 projecting portion 35 of the main shell 31 is firmly sandwiched between the crimping pieces 47 and 48 and the sleeve 13 together with the folded portion 11 a of the shield member 11. 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 convex portion 49 is pressed or pressed by a pressure member (not shown) incorporated in the crimper. At this time, the convex portion 49 and the first locking portion 50 are bent in such a manner that the central portion in the width direction (front-rear direction) orthogonal to the protruding direction of the convex portion 49 bulges toward the outer peripheral side. There is only one hitting position or pressing position on the outer peripheral surface of 49 in the center portion in the width direction, and an 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, a part of the convex portion 49, the first locking portion 50 and the concave portion 51 are formed so that the protruding portion 35 corresponds to the formation region from the inner peripheral side, and the front side The front end of the first locking portion 50 and the rear end of the rear first locking portion 50 are in contact with the outer peripheral surface of the protrusion 35. Therefore, when the convex portion 49 is struck or pressed, the curved convex portion 49 and the first locking portion 50 are stretched by being sandwiched between the pressing member and the protruding portion 35 (the curvature is increased). Deformed (to be smaller).

  In the process of deforming the curved convex portion 49 and the first locking portion 50 so as to extend, the front and rear first locking portions 50 are caused by the stress generated by the deformation in the convex portion 49 and the first locking portion 50. However, the protrusion 35 is elastically pressed toward the inner peripheral side while maintaining a state of sliding contact with the outer peripheral surface of the protrusion 35. Therefore, even if the radial dimension of the folded portion 11a sandwiched between the sleeve 13 and the protruding portion 35 varies, the folded portion 11a is securely sandwiched between the projected portion 35 and the sleeve 13. The protrusion 35 and the folded portion 11a are connected so as to be surely conductive, and the protrusion 35 and the fixing portion 34 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 convex portion 49 and the first locking portion 50 that are deformed so as to be stretched are formed such that the peripheral surfaces thereof are substantially flush with the peripheral surfaces of the arm portion 54 and the second caulking piece 48 (substantially smooth in the circumferential direction). And a shape along the outer peripheral surface of the protrusion 35 (a shape that comes into contact with the outer peripheral surface of the protrusion 35 in a face-to-face manner). 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 convex portion 49 and the first locking portion 50 are extended, the first locking portion 50 on the front side (the left side in FIG. 8) moves the locking portions 50, 53 from the front second locking portion 53. The rear first locking portion 50 is locked against the rear second locking portion 53 with respect to the thickness of the two locking portions 50 and 53 while being locked so as to abut in the circumferential direction within the range of the plate thickness. It is locked so as to abut in the circumferential direction within the range of. 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, the convex portion 49 is held in a state of entering the concave portion 51. Thereby, the fixing portion 34 is held in a state of being fixed to the shield member 11.

  Further, in a state in which the convex portion 49 and the first locking portion 50 are deformed so as to extend and the both locking portions 50 and 53 are locked, as shown in FIG. The front end edge of the recess 51 is strongly pressed against the front edge of the inner periphery of the recess 51, and the rear end edge of the rear first locking portion 50 is the rear of the inner periphery of the recess 51. It will be in the state pressed strongly with respect to the edge part of the side. Thus, since the 1st latching | locking part 50 is closely_contact | adhered so that it may press in an axial direction (front-back direction) with respect to the inner periphery of the recessed part 51, the backlash in the axial direction of a pair of crimping pieces 47 and 48 is attached. Is reliably prevented.

  Further, as shown in FIGS. 8 and 9, in both the circumferential direction and the axial direction, the region of the convex portion 49 that enters the concave portion 51 in the fixed state, the entire first locking portion 50, and the entire concave portion 51. The entirety of both arm portions 54 and the entire second locking portion 53 are disposed within the formation range of the protruding portion 35. As a result, the braided wire constituting the shield member 11 is likely to bite between the first caulking piece 47 and the second caulking piece 48 (that is, the convex portion 49 and the second locking portion 53 in the opening 52). The portion where the first locking portion 50 and the second locking portion 53 are locked in the recess 51, and the portion where the first locking portion 50 and the recess 51 are in close contact with each other) Is within the formation range of the protrusion 35 and is isolated from the shield member 11 (braided wire) by the protrusion 35. Therefore, when the fixing portion 34 and the shield member 11 are fixed, there is no possibility that the shield member 11 (braided wire) is caught between the first crimping piece 47 and the second crimping piece 48.

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

  In addition, when the convex portion is bent so as to be square along the fold in the circumferential direction, when the convex 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 convex portion may occur in the ridgeline portion or in the vicinity thereof. On the other hand, in this embodiment, since the convex 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 projection part 35 in the inner peripheral surface of the convex part 49 is excellent.

Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  As in the first embodiment, the shape of the first crimping piece 61 in the locked state of the convex portion 62 and the first locking portion 63 is a trapezoid that becomes narrower toward the protruding end of the convex portion 62. The edge portion along the axial direction of the first locking portion 63 is a first locking edge portion 64 perpendicular to the circumferential direction. In the second crimping piece 65, the shape of the arm portion 67 including the reinforcing portion 66 is the same as that of the first embodiment, but the edge portion of the second locking portion 68 that faces the recess 69 is in the axial direction (circumferential direction). The second locking edge portion 70 is in a direction perpendicular to the vertical direction.

  In a state where the first locking portion 63 and the second locking portion 68 are locked in the circumferential direction, the first locking edge portion 64 and the second locking edge portion 70 extend over the entire region in the axial direction. In addition, the edge of the oblique side of the first locking part 63 is in contact with the oblique edge of the reinforcing part 66. The front end edge of the first locking portion 63 on the front side contacts the front edge portion 71 of the inner peripheral edge of the recess 69, and the rear end edge of the first locking portion 63 on the rear side is the inner peripheral edge of the recess 69. Of these, the contact form that contacts the rear edge 71 is the same as in the first embodiment.

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the shapes of the convex portions 82 and the concave portions 85 are different from those of the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  Two pairs of first locking portions 83 spaced from each other in the protruding direction from the extending end edge of the first caulking piece 81 are formed on the front edge portion and the rear edge portion of the protrusion 82 so as to protrude. Yes. One recess 85 includes a pair of front and rear second locking portions 87 that project along the extending edge of the second crimping piece 84 so as to narrow the opening width of the opening 86, and the inner peripheral edge of the recess 85. Of these, a pair of third locking portions 88 projecting from the front edge and the rear edge are formed. The two pairs of first locking portions 83 are locked to the second locking portions 87 and the third locking portions 88, and by these locking actions, the two caulking pieces 81 and 85 are restricted from separating in the circumferential direction. Is done.

<Embodiment 4>
Next, a fourth embodiment of the present invention will be described with reference to FIG. In the fourth embodiment, the form of contact between the front end edge of the first locking portion 91 on the front side and the front edge portion of the inner peripheral edge of the recess 92, and the rear end edge of the first locking portion 91 on the rear side, The contact form with the rear edge of the inner peripheral edge of the recess 92 is different from that of the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  FIG. 15 shows a state in which the contact portion between the edge of the first locking portion 91 and the edge of the recess 92 is viewed in the axial direction. The edge of the first locking portion 91 and the edge of the recess 92 are both formed into a waveform in which a plurality of arc-shaped portions are continuous in the circumferential direction when viewed in the axial direction. The arcuate part of the edge and the arcuate part of the edge of the recess 92 are in contact with each other in a form shifted by ½ wavelength. With this configuration, even if the first locking portion 91 is displaced from the normal position with respect to the recess 92 in the plate thickness direction (vertical direction in FIG. 15), that is, the outer peripheral side or the inner peripheral side, The contact state between the edge of the portion 91 and the edge of the recess 92 is reliably maintained.

<Embodiment 5>
Next, a fifth embodiment of the present invention will be described with reference to FIGS. In the fifth embodiment, the shape of the pair of crimping pieces 147 and 148 in the fixing portion 134 of the subshell 132 is different from that of the subshell 32 of the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  Of the pair of caulking pieces, the first caulking piece 147 (one caulking piece that is a constituent of the present invention) has a plate-like shape protruding in a cantilevered manner from the extending end edge in the front-rear direction. A convex portion 149 is formed. The convex portion 149 is disposed at the center position in the front-rear direction of the extended end edge, and is a pair of first members formed so as to protrude from both front and rear side edges along the protruding direction (circumferential direction). A stop 150 is provided. The formation region of the first locking portion 150 in the circumferential direction (the protruding direction of the convex portion 149) is a substantially half region on the protruding end side of the convex portion 149. In addition, the pair of first locking portions 150 are symmetrical with respect to a virtual axis (not shown) in the circumferential direction.

  In the unfolded state before bending the metal plate 142 and the state in which the fixing part 134 is fixed to the shield member 11, the first locking part 150 is formed in the convex part 149 as shown in FIGS. 19 and 20. The region is trapezoidal so that it gradually becomes wider toward the protruding end. That is, the first locking portion 150 is formed with a first inclined edge portion 150a that is inclined with respect to the circumferential direction. In addition, the first locking portion 150 is formed with a first locking edge portion 150b that is disposed in a direction perpendicular to the circumferential direction so as to face the extended end edge of the first caulking piece 147. Yes. Furthermore, the protruding dimension (dimension in the circumferential direction) of the convex portion 149 is smaller than the width dimension (dimension in the circumferential direction) perpendicular to the protruding direction of the protrusion 35 described above.

  In a state after the metal plate material 142 is bent and before the fixing portion 134 is fixed to the shield member 11, as shown in FIGS. 16 and 17, the first locking portion 150 of the first caulking piece 147 is provided. The convex part 149 to be included is bent and formed into a shape curved in a substantially arc shape (generally a semicircular arc shape) when viewed in the circumferential direction. The convex form of the convex part 149 is such that the central part in the width direction orthogonal to the protruding direction (that is, the circumferential direction) of the convex part 149 from the first caulking piece 147 bulges toward the outer peripheral side. By bending the convex portion 149 in this way, the convex portion 149 including the first locking portion 150 has a width dimension perpendicular to the circumferential direction smaller than the opening width of the opening portion 152 of the concave portion 151 described later. The dimensions are narrow.

  Of the pair of caulking pieces 147, 148, the second caulking piece 148 (the other caulking piece which is a constituent element of the present invention) is formed with a recess 151 having an opening at the extending edge in the front-rear direction. . In the opening 152 of the recess 151, a pair of front and rear second locking portions 153 are formed so as to protrude along the extending end edge of the second caulking piece 148. The front second locking portion 153 protrudes rearward from the front edge of the opening 152, and the rear second locking portion 153 protrudes forward from the rear edge of the opening 152, By the pair of second locking portions 153, the recess 151 has a form in which the opening width of the opening 152 is narrowed. The formation region of the second locking portion 153 in the circumferential direction (the depth direction of the concave portion 151) is about ½ of the depth of the concave portion 151 on the opening 152 side. Moreover, the part which pinches | concludes the recessed part 151 from the front and back among the 2nd crimping pieces 148 becomes a pair of arm part 154, and the above-mentioned 2nd latching | locking part 153 has a form protruded from the front-end | tip of the arm part 154. .

  A pair of front and rear second inclined edge portions 155a inclined with respect to the circumferential direction is formed on the substrate portion 146 side (on the opposite side to the opening portion 152) of the opening edge of the recess 151 from the second locking portion 153. Yes. The inclination angle of the second inclined edge portion 155a is such that the convex portion 149 including the first locking portion 150 is extended and the first locking portion 150 and the second locking portion 153 are locked (deployed state). The angle is substantially the same as that of the first inclined edge 150a. Moreover, the edge part by the side of the board | substrate part 146 in the 2nd latching | locking part 153 is the 2nd latching edge 155b orthogonal to the circumferential direction. Furthermore, the opening width of the opening 152 is substantially the same as the width of the region of the convex portion 149 where the first locking portion 150 is not formed. In addition, the depth dimension of the recess 151 (the dimension in the circumferential direction from the extending end edge of the second caulking piece 148 to the rear end edge of the recess 151 on the substrate part 146 side) is substantially the same as the dimension in the circumferential direction of the projection 149. 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.

  In the process of connecting the fixing portion 134 and the shield member 11 using an automatic crimping machine (not shown) provided with an anvil and a crimper, both the crimping pieces 147 and 148 come into contact with the protruding portion 35, and thereafter The two crimping pieces 147 and 148 continue to be further deformed so that the extended end edges thereof are close to each other in the circumferential direction, and the convex portion 149 enters the concave portion 151 at the end of the deformation. Here, the convex portion 149 including the first locking portion 150 of the first caulking piece 147 is formed in a bent shape, and the first locking portion 150 is connected to the second locking portion 153 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 151. Specifically, as shown in FIG. 17, the convex portion 149 is bent so as to be bent in a substantially arc shape when viewed in the circumferential direction, thereby having a narrow form capable of passing through the opening 152 of the concave portion 151. Has been. Therefore, in the process in which both the crimps 147 and 148 are approaching in the circumferential direction, the convex portion 149 can enter the concave portion 151 without interfering with the second locking portion 153.

  When the convex portion 149 enters the concave portion 151 and the first locking edge portion 150b reaches the position aligned with the second locking edge portion 155b in the circumferential direction or slightly behind the concave portion 151, the crimper Is stopped, and the deformation in the circumferential direction of both the crimping pieces 147 and 148 (that is, the diameter reduction deformation of the fixing portion 134) 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 146 and the two crimping pieces 147 and 148, and the shield member 11 and the subshell 132 (shield shell 30) can be electrically connected. And is fixed in a state in which detachment is restricted by friction.

  After both the crimping pieces 147 and 148 are deformed and fixed to the shield member 11, the outer peripheral surface of the convex portion 149 is struck or pressed by a pressure member (not shown) incorporated in the crimper. At this time, the convex portion 149 including the first locking portion 150 is bent in such a manner that the central portion in the width direction (front-rear direction) orthogonal to the protruding direction of the convex portion 149 is expanded toward the outer peripheral side. The hitting position or pressing position on the outer peripheral surface of the portion 149 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, the entire convex portion 149 including the first locking portion 150, the entire opening area of the concave portion 151, and both the front and rear arm portions 154 are included in the formation range of the protruding portion 35 on the inner peripheral side. The front end of the first locking portion 150 on the front side and the rear end of the first locking portion 150 on the rear side are in contact with the outer peripheral surface of the protrusion 35. Therefore, when the convex portion 149 is struck or pressed, the curved convex portion 149 is bent in the radial direction between the pressing member and the protruding portion 35 so that the curvature is extended (the curvature becomes small). To be deformed).

  In the process of deforming the curved convex portion 149 so as to extend, the convex portion 149 keeps the state in which it slides on the outer peripheral surface of the protruding portion 35 at both the front and rear first locking portions 150 from the beginning while maintaining the radial direction as a whole. Displacement inward (direction approaching the protrusion 35). Similarly, in the process in which the convex part 149 is deformed, the front and rear first locking parts 150 keep a state of elastically pressing the protruding part 35 toward the inner peripheral side due to the stress generated by the deformation in the convex part 149. 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 134 (convex portion 149) 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 132 (former base for forming the fixing portion 134) are connected to each other so as to be electrically conductive with each other. Is done.

  The convex portion 149 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 154 and the second caulking piece 148 (a shape in which the protrusions 149 are continuously connected 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 154 and the second locking portions 153 are also in contact with the outer peripheral surface of the protruding portion 35 in a face-to-face manner.

  When the convex portion 149 is extended, the first locking edge 150b of the first locking portion 150 on the front side (the left side in FIG. 20) is opposed to the second locking edge 155b of the second locking portion 153 on the front side. The first locking edge 150b of the first locking portion 150 on the rear side is fixed to the second locking portion 150 on the rear side. The second locking edge portion 155b of the locking portion 153 is locked so as to abut on the circumferential direction within the range of the plate thickness of both the locking portions 150 and 153. Due to the locking action at the two front and rear positions, the two caulking pieces 147 and 148 are restricted from being separated in the circumferential direction (up and down direction in FIG. 20), and consequently, the expansion and deformation of the fixing portion 134 is prevented.

  Further, when the convex portion 149 is extended, the first inclined edge portion 150a of the first locking portion 150 on the front side has a thickness of both the locking portions 150 and 153 with respect to the inclined edge portion 155a on the front side of the concave portion 151. The first inclined edge 150a of the first locking portion 150 on the rear side is locked against the inclined edge 155a on the rear side of the recess. It latches so that it may contact | abut in the circumferential direction within the range of the board thickness of 153. Also by the locking action at the two front and rear positions, separation of both the crimping pieces 147 and 148 in the circumferential direction is restricted, and the expansion and deformation of the fixing portion 134 is prevented.

  As described above, in the present embodiment, since both the first inclined edge portion 150a and the second inclined edge portion 155a are inclined with respect to the circumferential direction, the front and rear are increased as the convex portion 149 is extended. At the end of the process in which the distance between the first inclined edges 150a gradually increases, a wedge action occurs due to the contact between the first inclined edges 150a and the second inclined edges 155a. Due to the wedge action, the convex portion 149 is displaced in a direction returning to the opening portion side with respect to the concave portion 151 (that is, both the caulking pieces 147 and 148 are separated in the circumferential direction and the diameter of the fixing portion 134 is enlarged). Is prevented. Further, since both the first inclined edge portion 150a and the second inclined edge portion 155a are close to the direction perpendicular to the axial direction, a pair of caulking pieces 147, The backlash of 148 in the axial direction is also reliably prevented.

  At the end of the process in which the convex portion 149 is extended, the caulking pieces 147 and 148 may be slightly displaced in the approaching direction due to the wedge action, so that the extended edge of the convex portion 149 and the concave portion 151 It is preferable to leave a slight clearance between the rear edge and between the extended edge of the first caulking piece 147 and the extended edge of the second caulking piece 148.

  In addition, as shown in FIG. 20, in both the circumferential direction and the axial direction, the entire convex portion 149 including the first locking portion 150, the entire opening area of the concave portion 151, and both arms including the second locking portion 553. All of the portions 154 are disposed within the formation range of the protrusions 35. In this arrangement, in the process of fixing the fixing part 134 to the shield member 11 and the projecting part 35 and the process of deforming the protruding part 149 to extend, the braided wire constituting the shield member 11 is connected to the first caulking piece 147 and the second caulking piece 147. A portion that may be caught between the caulking pieces 148 (that is, an approaching portion between the extending end edge of the first caulking piece 147 and the extending end edge of the second caulking piece 148, and the extending end edge of the convex portion 149 And the rear end edge of the recess 151, the portion where the convex portion 149 enters in the opening 152, and the first locking portion 150 (first locking edge portion 150 b) and the second locking portion 153 in the recess 151. (The second locking edge portion 155b) approaches and locks, and the first inclined edge portion 150a and the second inclined edge portion 155a approach and lock each other) Within the formation range of the portion 35, It has become isolated state from Rudo member 11 (braided wire). Therefore, when the fixing part 134 and the shield member 11 are fixed, there is no possibility that the shield member (braided wire) is caught between the first crimping piece 147 and the second crimping piece 148.
