Description

TECHNICAL FIELD

[0001] The present disclosure relates to a connector. BACKGROUND

[0002] The connector described in Patent Literature 1 is provided with a cover portion and a movable plate that is movably arranged in the cover portion between an initial position and a final position (a fitted position). A tab of a male terminal member is arranged in the cover portion. The movable plate has a holding hole (a positioning hole) through which the tab passes, and protects the tab. The male terminal member is caught in a lance-shaped portion that is elastically deformable in a body portion (a housing portion). The movable plate integrally has a stopper that is arranged in an elastic space of the lance-shaped portion in the final position. By arranging the stopper in the elastic space of the lance-shaped portion, the elastic action of the lance-shaped portion can be restricted, and the male terminal member is doubly caught. Patent Literature 2 also discloses a stopper that is integral with a movable plate. Patent Literature 3 discloses a technique for moving the movable plate to the initial position from the fitted position when the female side housing is detached. Patent Literature 4 discloses a technique in which a movable plate and a front stopper are respectively moved separately.

[0008] Patent Literature 4: Japanese Patent Application Publication No. 2019-212404 SUMMARY

[0009] PROBLEMS TO BE SOLVED BY THE INVENTION

[0010] Patent Literature 3 does not have a front stopper. Patent Literature 4 has difficulty in moving the front stopper because the movable plate is arranged in front of the front stopper. In contrast, Patent Literatures 1 and 2 enable the stopper corresponding to the front stopper to be moved in conjunction with the movement of the movable plate. However, in the case of Patent Literatures 1 and 2, when the movable plate is in the initial position, the stopper is positioned further forward than the elastic space of the lance-shaped portion, and thus the doubly caught state of the male terminal member cannot be achieved at times.

[0011] Therefore, the present disclosure aims to provide a connector that can achieve the doubly caught state of the male terminal member by the front stopper even when the movable plate is in the initial position.

[0012] MEANS FOR SOLVING THE PROBLEMS

[0013] The connector of the present disclosure includes a male terminal member having a tab, a housing portion having a lance portion that is elastically deformable, a cover portion protruding forward from the housing portion, a movable plate movably disposed in the cover portion between an initial position and a fitting position, and a front stopper movably disposed in the cover portion between a standby position and a locking position. The male terminal member is locked to the lance portion in the housing portion, and the tab is disposed to protrude into the cover portion. The movable plate has a positioning hole through which the tab passes, and is disposed further forward than the fitting position in the initial position. The front stopper has a restriction portion disposed in an elastic space of the lance portion in the locking position, and is disposed further forward than the locking position in the standby position. The movable plate has a locking receiving portion, and the front stopper has a locking portion that is locked to the locking receiving portion in a manner that moves from the locking position to the standby position in conjunction with movement of the movable plate from the fitting position to the initial position. The locking portion is detachable with respect to the locking receiving portion.

[0031] [Explanation of Embodiments of the Present Disclosure]

[0032] First, an embodiment of the present disclosure will be explained.

[0033] The connector of the present disclosure,

[0034] ​(1) has: a male terminal part having a tab; a housing portion having a lance portion that can be flexibly deformed; a cover portion protruding forward from the housing portion; a movable plate movably disposed in the cover portion between an initial position and a fitting position; and a front stopper movably disposed in the cover portion between a standby position and a locking position, the male terminal part being locked to the lance portion in the housing portion, the tab being disposed to protrude into the cover portion, the movable plate having a positioning hole through which the tab passes, the movable plate being disposed further forward than the fitting position from the housing portion in the initial position, the front stopper having a restriction portion disposed in a flexing space of the lance portion in the locking position, the front stopper being disposed further forward than the locking position from the housing portion in the standby position, the movable plate having a locking receiving portion, the front stopper having a locking portion that is locked to the locking receiving portion in a manner that moves from the locking position to the standby position in conjunction with movement of the movable plate from the fitting position to the initial position, the locking portion being detachable with respect to the locking receiving portion.

[0035] The front stopper moves from the locking position to the standby position in conjunction with movement of the movable plate from the fitting position to the initial position by the locking portion being locked to the locking receiving portion, so it is not necessary to separately perform a movement operation of the front stopper to the standby position, and workability is excellent.

[0036] The locking portion is detachable with respect to the locking receiving portion, so when the movable plate is in the initial position, the locked state of the locking portion and the locking receiving portion is released, and the front stopper can be moved from the standby position to the locking position. Therefore, even when the movable plate is in the initial position, the front stopper reaches the locking position, the restriction portion is disposed in the flexing space of the lance portion, and a double-locked state of the male terminal part can be achieved.

[0037] (2) Preferably, the locking portion protrudes forward from a front surface of the front stopper, has a locking main body at a tip end portion, the locking receiving portion has a locking hole formed through in a front-rear direction in the movable plate and a locking surface exposed on the front surface of the movable plate, the locking portion is disposed in the locking hole, and the locking main body can be locked to the locking surface.

[0038] When the movable plate is in the initial position, the locking main body is released from the locking surface by a jig or the like being applied to the locking main body exposed on the front surface side of the movable plate from the front of the cover portion, so the locked state of the locking portion and the locking receiving portion can be released. After the locked state of the locking portion and the locking receiving portion is released, the front stopper can be brought to the locking position by being pressed toward the housing portion side.

[0039] The locked state and the released state of the locking portion and the locking receiving portion can be visually confirmed from the front of the cover portion of the connector 10 or with a sensor.

[0040] (3) Alternatively, the connector may have a female housing that fits into the cover, the female housing having a hook receiving portion, the moving plate having a hook portion, the hook portion being engaged with the hook receiving portion in such a way that it moves from the fitted position to the initial position in conjunction with the female housing disengaging from the cover, the hook portions being arranged in pairs in the width direction on one side of the moving plate in the height direction, and the engaging receiving portion being arranged in pairs in the width direction on the other side of the moving plate in the height direction.

[0041] The latching part is engaged with the latching receiving part, thereby disengaging from the cover and moving the moving plate from the engaged position to the initial position. Therefore, it is not necessary to perform the moving plate movement operation to the initial position independently, resulting in excellent workability.

[0042] The card-hanging part is located on one side of the moving plate in the height direction, and the locking and receiving part is located on the other side of the moving plate in the height direction, so that the card-hanging part and the locking and receiving part can be formed with a high degree of freedom. In addition, the card-hanging part and the locking and receiving part are arranged in pairs in the width direction in the moving plate, so that the moving plate and the front stop can move smoothly and steadily to the initial position and the standby position respectively.

Figure 1 The upper side is set as the upper side. Figure 1 The "U" is on the top side, and the "D" is on the bottom side.

[0047] <Corneal shell>

[0048] The female shell 81 is made of synthetic resin, such as Figure 9As shown, the housing 81 has a small female cavity 82, a medium female cavity 83, and a large female cavity 84. Multiple small female cavities 82 are formed at the center of the lower portion of the female housing 81 in the width direction (left-right direction). Multiple medium female cavities 83 are formed on both sides of the lower portion of the female housing 81 in the width direction, with openings larger than the small female cavities 82. Multiple large female cavities 84 are formed on both sides of the upper portion of the female housing 81 in the width direction, with openings larger than the medium female cavities 83. Female terminal parts 85 of corresponding sizes are inserted and housed from the rear into the small female cavity 82, the medium female cavity 83, and the large female cavity 84. For example, the female terminal part 85 housed in the large female cavity 84... Figure 2 and Figure 3 As shown in the image.

[0049] A space 86 extending through the front-rear direction is formed on the central side of the upper part of the female housing 81 in the width direction. The space 86 houses a component (not shown) for connecting the coaxial terminal 13 to the opposite side. A shaft portion 87 for a support rod (not shown) is formed protruding from the central part of the upper and lower surfaces of the female housing 81 in the width direction.

[0050] On the front surface of the female housing 81, a rib receiving portion 88, generally considered to be T-shaped, is formed between each female-side cavity 82. In the lower part of the female housing 81, a pair of engaging holes 89 are formed through the width direction between each female-side cavity 82 and each female-side central cavity 83. A releasing portion 91 is formed protruding from the inner side of each engaging hole 89 in the width direction. In the lower part of the female housing 81, on one side in the width direction (… Figure 9 The lower surface of the engaging hole 89 on the right side and the other side in the width direction ( Figure 9 A pair of clip receiving portions 92 are formed protruding from the upper surface of the engaging hole 89 (on the left side). A wire cover (not shown) is fitted from the rear of the female housing 81, which covers the wire 200 connected to the female terminal part 85. (As shown) Figure 2 and Figure 3 As shown, an assembly part 93 for locking the wire cover is formed protruding rearward on the female housing 81.

[0051] <Male housing, male terminal components, coaxial terminals>

[0052] The anode shell 11 is made of synthetic resin, such as... Figure 1 As shown, it has a housing portion 17 and a cover portion 18 protruding forward from the housing portion 17.

[0053] like Figure 10As shown, the housing portion 17 has a male-side small cavity 19, a male-side middle cavity 21, a male-side large cavity 22, and a coaxial cavity 23. Multiple male-side small cavities 19 are formed on the central side of the lower portion of the housing portion 17 in the width direction. Multiple male-side middle cavities 21 are formed on both sides of the lower portion of the housing portion 17 in the width direction, with openings larger than those of the male-side small cavities 19. Multiple male-side large cavities 22 are formed on both sides of the upper portion of the housing portion 17 in the width direction, with openings larger than those of the male-side middle cavities 21. Spear-shaped portions 24 capable of bending and deformation are protruding from the male-side small cavity 19, the male-side middle cavity 21, and the male-side large cavity 22. Furthermore, a stop body mounting hole 25 communicating with the male-side small cavity 19 and the male-side middle cavity 21 is formed on the lower surface of the housing portion 17 (see reference). Figure 1 The stop 14 is inserted into the stop mounting hole 25 on the side. Figure 2 As shown, a stop body mounting hole 25 for the insertion-side stop body 14 is also formed in the female housing 81.

[0054] The male terminal component 12, corresponding to its respective size, is inserted and housed from the rear into the male-side small cavity 19, male-side medium cavity 21, and male-side large cavity 22. For example, the male terminal component 12 housed in the male-side large cavity 22... Figures 1-3 As shown in the image.

[0055] The male terminal component 12 is made of conductive metal, such as Figures 1-3 As shown, the device has a cylindrical male terminal body 26, a protrusion 27 protruding forward from the male terminal body 26, and a cylindrical portion 28 connected to the rear of the male terminal body 26. A spear-shaped hole 29 is formed in the opening of the male terminal body 26. By inserting the protrusion of the spear-shaped portion 24 into the spear-shaped hole 29, the male terminal part 12 is initially locked, and the rearward dislodgement of the male terminal part 12 is restricted.

[0056] The male terminal parts 12, which are inserted into the male-side small cavity 19 and the male-side middle cavity 21 respectively, are locked in a secondary manner by the side stop 14, and are doubly locked together with the spear-shaped part 24. In contrast, the male terminal parts 12, which are inserted into the male-side large cavity 22, are locked in a secondary manner by the front stop 16, which will be described later.

[0057] The tab 27 protrudes into the cover portion 18 and is electrically connected to the female terminal part 85 when the female housing 81 and the male housing 11 are engaged. The cylindrical portion 28 is electrically connected to and mechanically crimped to the end portion of the wire 100.

[0058] like Figure 10 As shown, on the front surface of the housing portion 17, ribs 31 extending in the width direction are formed protruding between each male-side small cavity 19 and each coaxial cavity 23. On the lower part of the housing portion 17, a pair of engaging tabs 32 are formed protruding forward in the width direction between each male-side small cavity 19 and each male-side central cavity 21.

[0059] likeFigure 4 and Figure 8 As shown, the latching tab 32 has a front retaining portion 33 and a rear retaining portion 34. The front retaining portion 33 protrudes inward from the center side in the height direction of the inner surface of the latching tab 32 (the inner side of the width direction of each latching tab 32 facing each other). The rear retaining portion 34 protrudes in pairs from both sides in the height direction of the inner surface of the latching tab 32, further rear than the front retaining portion 33.

[0060] like Figure 10 As shown, multiple coaxial cavities 23 are formed on the central side of the upper portion of the housing 17 in the width direction. Multiple coaxial cavities 23 are also formed on the central side of the lower portion of the housing 17 in the width direction. Each coaxial cavity 23 has a circular cross-section and an opening diameter larger than the larger cavity 22 on the male side. A pair of flexible, spear-shaped coaxial portions 35 are formed protruding in the width direction on the upper portion of each coaxial cavity 23. Furthermore, the housing 17 has stop portions 36 extending radially inward from the inner circumference of each coaxial cavity 23.

[0061] like Figure 4 As shown, a coaxial terminal 13 is inserted and housed from the rear into the coaxial cavity 23. The coaxial terminal 13 is made of conductive metal, is cylindrical, and is electrically and mechanically connected to the end of the coaxial cable 300. The coaxial terminal 13 has a front flange 37 and a rear flange 38 extending radially outward. When the coaxial terminal 13 is inserted into the correct position in the coaxial cavity 23, the front flange 37 is blocked by the stop 36, and the coaxial spear-shaped portion 35 is positioned opposite and locked to the rear surface of the rear flange 38. This restricts the coaxial terminal 13 from detaching from the coaxial cavity 23. Furthermore, after the coaxial terminal 13 is initially locked by the coaxial spear-shaped portion 35, it is further secured by the coaxial limiting portion 63 (see below). Figure 13 The coaxial terminal 13 is locked in a secondary manner to limit the flexural movement of the spear-shaped portion 35. The top end of the coaxial terminal 13 is configured to protrude into the cover portion 18.

[0062] like Figure 10 As shown, cam followers 39, capable of engaging with a rod (not shown), are formed at the center of the width direction of both the upper and lower ends of the housing portion 17. The cover portion 18 is cylindrical and is formed to be one size larger than the housing portion 17. Figures 2-4 As shown, the female shell 81 is fitted into the cover portion 18.

[0063] <Motion Board>

[0064] The movable plate 15 is made of synthetic resin and is inserted into the cover 18 from the front. It can be positioned relative to the male housing 11 in the initial position (see reference). Figure 1 , Figure 2 as well as Figure 4 ) and the fitting position (refer to Figure 3 and Figure 5The movable plate 15 is movably disposed between the initial position and the fitting position. The movable plate 15 has a plate body 41 which is a plate-shaped member covering the inside of the cover portion 18.

[0065] As shown in Figure 11 , the plate body 41 has a plurality of small positioning holes 42, a plurality of middle positioning holes 43, a plurality of large positioning holes 44, and a plurality of coaxial insertion holes 45. The small positioning holes 42 are formed at the lower portion of the plate body 41 on the width direction center side. The middle positioning holes 43 are formed at the lower portion of the housing portion 17 on both width direction sides in a manner that they are larger than the small positioning holes 42. The large positioning holes 44 are formed at the upper portion of the plate body 41 on both width direction sides in a manner that they are larger than the middle positioning holes 43. The coaxial insertion holes 45 are formed at the upper portion of the plate body 41 on the width direction center side in a manner that they are larger than the large positioning holes 44.

[0066] As shown in Figures 1-5 , in a state where the movable plate 15 is inserted into the cover portion 18, the small positioning holes 42, the middle positioning holes 43, the large positioning holes 44, and the coaxial insertion holes 45 are disposed in front of each of the male-side small cavity 19, the male-side middle cavity 21, the male-side large cavity 22, and the coaxial cavity 23. The tabs 27 of the male terminal parts 12 of respective sizes are inserted into the small positioning holes 42, the middle positioning holes 43, and the large positioning holes 44. The top end portions of the coaxial terminal 13 are inserted into the coaxial insertion holes 45. The coaxial insertion holes 45 are formed in a circular cross section, and the top end portions of the coaxial terminal 13 are retracted into the coaxial insertion holes 45 when the movable plate 15 moves.

[0067] When the movable plate 15 is located at the initial position, the plate body 41 is disposed to be away from the front surface of the housing portion 17 in the front direction (see Figure 1 ), and the top end portions (front end portions) of the tabs 27 are respectively disposed in the small positioning holes 42, the middle positioning holes 43, and the large positioning holes 44. When the movable plate 15 is located at the fitting position, the plate body 41 is disposed to be close to or in contact with the front surface of the housing portion 17 (see Figure 3 ), and the base end portions (rear end portions) of the tabs 27 are respectively disposed in the small positioning holes 42, the middle positioning holes 43, and the large positioning holes 44. The tabs 27 are protected by the plate body 41, and can maintain the shape extending in the front-rear direction.

[0068] A rib insertion hole 46 extending in the width direction is formed above each of the small positioning holes 42 in the plate body 41. As shown in Figure 4 , the rib 31 is inserted into the rib insertion hole 46.

[0069] As shown in Figure 11 , in the plate body 41, a pair of through holes 47 are formed in the width direction between each of the small positioning holes 42 and each of the middle positioning holes 43. As shown in Figure 8 , the engaging pieces 32 are inserted into the through holes 47.

[0070] like Figure 4 As shown, when the movable plate 15 is in the initial position, the front retaining portion 33 of the engaging tab 32 is configured to contact the front surface of the plate body 41, and the rear retaining portion 34 of the engaging tab 32 is configured to contact the rear surface of the plate body 41. Thus, the movable plate 15 is held in a state where its movement relative to the male housing 11 is restricted in the initial position.

[0071] like Figure 11 As shown, on the lower part of the front surface of the main body 41, on one side in the width direction ( Figure 11 The lower part of the through hole 47 on the left side and the other side in the width direction ( Figure 11 A pair of hook portions 48 are formed protruding above the through hole 47 on the right side. A hook protrusion 49 is formed at the top (front) end of the hook portion 48. The hook protrusion 49 of the hook portion 48 on one side in the width direction protrudes downward, and the hook protrusion 49 of the hook portion 48 on the other side in the width direction protrudes upward.

[0072] The card holder 48 is inserted into the engagement hole 89 of the female housing 81. For example... Figure 8 As shown, the hook protrusion 49 of the hook part 48 can be hooked onto the hook receiving part 92 of the female shell 81.

[0073] like Figure 11 As shown, on both sides of the upper width of the plate body 41, locking receiving portions 51 are formed in pairs between each coaxial through hole 45 and each large positioning hole 44. Each locking receiving portion 51 has a locking hole 52 that passes through the plate body 41 in the front-rear direction, which is the plate thickness direction. The locking hole 52 is formed in a rectangular opening shape that is elongated in the vertical direction. A locking rib 53 is formed protruding from the side surface inside the width direction and at the center in the vertical direction of the locking hole 52. The locking rib 53 extends in the vertical direction and has a locking surface 54 on its front surface. The adjacent portion of the locking surface 54 and the front surface of the plate body 41 is continuous without steps. A chamfered portion 55 is formed at the front and rear corners of each locking rib 53, intersecting and connecting with the locking surface 54.

[0074] like Figures 1-5 As shown, the movable plate 15 has a peripheral wall 56 that protrudes rearward from the outer edge of the plate body 41. The peripheral wall 56 is configured to contact the inner periphery of the cover portion 18.

[0075] <Front stopper>

[0076] The front stop 16 is made of synthetic resin, such as Figures 1-5 As shown, it is disposed within the cover portion 18 between the housing portion 17 and the plate body 41. The front stop 16 is configured to be in the standby position relative to the male housing 11 (see reference). Figure 1 ) and the stopping position (refer to) Figures 2-5 Move between ( ). For example, Figure 1As shown, the front stop 16 is positioned opposite the upper part of the rear surface of the plate body 41.

[0077] like Figure 12 and Figure 13 As shown, the front stop 16 is formed in a shape that is elongated in the width direction, having a stop base 57 and a pair of stop ends 58 connected to both sides of the stop base 57 in the width direction. A plurality of coaxial through holes 59 are formed through the stop base 57. Each coaxial through hole 59 has a circular cross-section and is arranged in a manner along the width direction of the stop base 57. Figure 4 As shown, the coaxial terminal 13 is inserted into the coaxial through hole 59.

[0078] A frame portion 61 is formed protruding from the opening edge of each coaxial through hole 59 in the rear surface of the base 57 of the stop body. Multiple notches 62 are formed at intervals in the width direction on the upper and lower parts of the frame portion 61. Each notch 62 penetrates the upper and lower parts of the frame portion 61 in the vertical direction and opens at the rear. Figure 13 As shown, a coaxial limiting part 63 is formed on the upper part of the frame part 61, which is connected in a wave-like manner in the width direction through the notches 62. When in the locked position, the coaxial limiting part 63 contacts the coaxial spear-shaped part 35 from above, limiting the bending movement of the coaxial spear-shaped part 35.

[0079] A through hole 64 is formed through each end 58 of the stop body. Each through hole 64 is formed in a rectangular opening shape that is longer in the width direction at the end 58 of the stop body.

[0081] A limiting portion 65 is formed protruding from the upper and lower portions of the opening edge of the through hole 64 in the rear surface of each stop body end 58. The limiting portion 65 is plate-shaped, with the plate surface facing upward and downward. The limiting portion 65 is positioned in the deflection space below the spear-shaped portion 24 in the locked position. The upper surface of the limiting portion 65 contacts the spear-shaped portion 24, thereby limiting the deflection movement of the spear-shaped portion 24.

[0082] End wall portions 66 are formed rearwardly at both ends of the front stop 16 in the width direction. The end wall portions 66 are plate-shaped, with the plate surface facing the width direction at the outer end of the stop end 58. For example... Figure 5 As shown, the end wall portion 66 is configured to contact the inner surface of the peripheral wall 56 of the moving plate 15.

[0083] like Figure 12As shown, the front stopper 16 has a pair of locking portions 67 that protrude forward from the ends of the front surface of the stopper base 57 on both widthwise sides. Each locking portion 67 is disposed on the widthwise inner side of each stopper end 58. Each locking portion 67 is plate-shaped with the plate face facing the widthwise direction and is capable of flexibly deforming in the widthwise direction. The inner surfaces of the widthwise inner sides of the locking portions 67 opposite each other are formed with locking recesses 68. The locking recesses 68 are rectangular in side view and are recesses with bottoms whose perimeters are defined by the upper and lower ends and the front end of the inner surfaces of the locking portions 67. The locking recesses 68 communicate with the coaxial through holes 59. The front end of the inner surface of the locking portion 67 is formed as a locking main body 69 along the up-down direction. The rear surface of the locking main body 69, or in other words, the front surface of the locking recess 68, is disposed along the up-down direction and the widthwise direction. The locking main body 69 of the locking portion 67 is capable of being locked in the locking surface 54 of the locking receiving portion 51.

[0084] <Assembly structure of connector, fitting method, and separation method>

[0085] First, the front stopper 16 is assembled to the movable plate 15 from the rear. During assembly of the front stopper 16, the locking portions 67 are inserted into the locking holes 52 of the plate main body 41 from the rear. The locking main bodies 69 of the locking portions 67 interfere with the locking ribs 53, and thus the locking portions 67 flexibly deform. When the front stopper 16 is normally assembled, the flexed state of the locking portions 67 is released, the locking ribs 53 are inserted into the locking recesses 68, and the locking main bodies 69 of the locking portions 67 are hung in opposition to the locking surface 54 of the locking ribs 53 (see Figure 5 and Figure 6 ). The front surfaces of the stopper base 57 and the stopper ends 58 are disposed in opposition to the rear surface of the plate main body 41. Thus, the front stopper 16 is assembled to the movable plate 15 in a state in which it is restricted from moving in the forward and rearward directions.

[0086] Next, the movable plate 15 with the front stopper 16 assembled is assembled into the cover portion 18 of the male housing 11 from the front. During assembly of the movable plate 15, the engaging pieces 32 of the male housing 11 are inserted through the through holes 47. When the movable plate 15 is normally assembled, the front holding portion 33 is disposed in opposition to the front surface of the plate main body 41, and the rear holding portion 34 is disposed in opposition to the rear surface of the plate main body 41 (see Figure 4 ). Thus, the movable plate 15 is held in a state in which it is restricted from moving in the forward and rearward directions in the initial position relative to the male housing 11. At the same time, the front stopper 16 is disposed in the standby position relative to the male housing 11 by the movable plate 15.

[0087] When the movable plate 15 is in the initial position, the plate main body 41 is disposed so as to be spaced forward from the housing portion 17 (see Figure 1). Also, when the front stopper 16 is in the standby position, the stopper base 57 and the stopper end 58 are arranged to be away from the housing portion 17 in the front direction. The restriction portion 65 of the stopper end 58 is arranged in the front direction from the flexing space of the lance portion 24 of the male large cavity 22. Therefore, the lance portion 24 of the male large cavity 22 is in a state capable of flexing deformation.

[0088] Next, the male terminal member 12 is inserted into the male large cavity 22 of the housing portion 17 from the rear. The male terminal member 12 makes the protruding portion of the lance portion 24 embedded into the lance hole 29 after the lance portion 24 is flexed and deformed, and preliminarily latched with the housing portion 17. The tab 27 of the male terminal member 12 protrudes into the cover portion 18, and the tip end portion is inserted through the large positioning hole 44 of the plate main body 41 and the like. Thus, the state in which the tab 27 of the male terminal member 12 is arranged in the front-rear direction can be maintained.

[0089] Next, the rod-shaped jig 400 (refer to Figure 14 ) is inserted into the cover portion 18 from the front. As shown in Figure 14 , the tip end portion of the jig 400 is obliquely pressed against the corner inclined surface of the latching main body 69 of the latching portion 67 exposed on the front surface of the plate main body 41, and thus the latching main body 69 is displaced from the latching surface 54 to the inclined surface portion 55 side, and the latching state of the latching portion 67 and the latching receiving portion 51 is released. Further, as shown in Figure 15 , the jig 400 is pressed in the rear direction, and thus the movable plate 15 is left in the initial position, and only the front stopper 16 is pressed by the jig 400 and moved to the housing portion 17 side. In this way, the front stopper 16 can reach the latched position. In the latched position, the stopper base 57 and the stopper end 58 are arranged to be capable of contacting the front surface of the housing portion 17 (refer to Figure 2 ). In addition, in the latched position, the restriction portion 65 of the stopper end 58 enters the flexing space above the lance portion 24 of the male large cavity 22, and the flexing action of the lance portion 24 is restricted, and thus the male terminal member 12 is secondarily latched.

[0090] Further, when the front stopper 16 reaches the latched position, the coaxial restriction portion 63 enters the flexing space above the coaxial lance portion 35, and the flexing action of the coaxial lance portion 35 is also restricted, and thus the coaxial terminal 13 is secondarily latched. Specifically, in the state in which the coaxial restriction portion 63 shown in Figure 4 is arranged above the coaxial lance portion 35 shown in Figure 13 , the secondary latching state of the coaxial terminal 13 is achieved. The respective male terminal members 12 arranged in the male small cavity 19 and the male middle cavity 21 are secondarily latched by the side stopper 14 inserted into the stopper mounting hole 25 from below the housing portion 17.

[0091] Next, the female housing 81 is shallowly fitted into the cover portion 18 of the male housing 11 from the front. Figure 9The release part 91 of the female shell 81 shown is... Figure 10 The front retaining part 33 of the male housing 11 is interfered with and pressed, and the engaging piece 32 moves towards the front retaining part 33. Figure 10 The left and right outer sides flex and deform, thereby releasing the holding state of the moving plate 15 relative to the male housing 11 in its initial position. The hook portion 48 of the moving plate 15 is inserted into the engaging hole 89, so that the hook protrusion 49 at the top end is engaged with the rear surface of the hook receiving portion 92 (the rear surface viewed from the female housing 81) (see reference). Figure 8 ).

[0092] When the female housing 81 and the male housing 11 are engaged by rotating the rod (not shown), the movable plate 15 moves from the initial position toward the engaged position. During the movement of the movable plate 15, the engaging piece 32 is inserted into the engaging hole 89 of the female housing 81 through the through hole 47, and the rib 31 is inserted into the rib receiving part 88 of the female housing 81 through the rib insertion through hole 46 of the movable plate 15 (see reference). Figure 4 Therefore, the tilting of the moving plate 15 during the movement is restricted. When the moving plate 15 reaches the mating position, the female housing 81 and the male housing 11 are in a properly mated state (see reference). Figure 3 The tab 27 of the male terminal part 12 is inserted into the female terminal part 85 at the correct depth and electrically connected to it. In addition, when the moving plate 15 reaches the mating position, the locking part 67 is inserted into the locking hole 52, so that the locking body 69 at the top end is locked onto the locking surface 54.

[0093] When the female housing 81 and male housing 11 are detached for maintenance or other reasons, the rod (not shown) is rotated in the detachment direction. When the female housing 81 moves away from the housing portion 17, the hook protrusion 49 of the hook portion 48 remains locked with the hook receiving portion 92, thus moving in conjunction with the female housing 81, the moving plate 15 also moves toward the initial position. Then, when the moving plate 15 moves toward the initial position, the locking body 69 of the locking portion 67 remains locked with the locking receiving portion 51, thus moving in conjunction with the moving plate 15, the front stop body 16 also moves toward the standby position.

[0094] When the movable plate 15 returns to its initial position, the front retaining part 33 is again opposed to the front surface of the plate body 41, restricting further movement of the movable plate 15. Then, the locking state of the latching part 48 and the latching receiving part 92 is released, and the female housing 81 keeps the movable plate 15 in its initial position and moves away from the cover part 18. Here, the locking state of the latching part 67 and the latching receiving part 51 can be maintained, so when the movable plate 15 returns to its initial position, the front stop body 16 can also return to the standby position. When the front stop body 16 is in the standby position, the spear-shaped part 24 becomes a flexible and deformable state. Therefore, by bending the spear-shaped part 24 and pulling the wire 100 with a spear-shaped part locking release jig (not shown), the male terminal part 12 can be pulled out from the male side cavity 22.

[0095] As described above, according to the present embodiment 1, the front stopper 16 is moved from the locked position to the standby position in conjunction with the movement of the movable plate 15 from the fitted position to the initial position by the locking portion 67 being locked in the locking receiving portion 51, and thus it is not necessary to independently perform the movement operation of the front stopper 16 to the standby position, and workability is excellent.

[0096] Further, the locking portion 67 is detachable with respect to the locking receiving portion 51, and thus when the movable plate 15 is positioned at the initial position, the locked state of the locking portion 67 and the locking receiving portion 51 is released, and the front stopper 16 can be moved from the standby position to the locked position. Thus, even when the movable plate 15 is positioned at the initial position, the front stopper 16 reaches the locked position, and the restriction portion 65 is disposed in the flexing space of the lance portion 24, and a double-locked state of the male terminal part 12 can be achieved.

[0097] In addition, when the movable plate 15 is positioned at the initial position, the locking body 69 is detached from the locking surface 54 by the jig 400 or the like being applied to the locking body 69 exposed on the front surface side of the movable plate 15 from the front of the cover portion 18, and thus the locked state of the locking portion 67 and the locking receiving portion 51 can be released. After the locked state of the locking portion 67 and the locking receiving portion 51 is released, the front stopper 16 can be brought to the locked position by the front stopper 16 being pressed into the housing portion 17 side with the jig 400. When the connector 10 is not small, the locked state and the released state of the locking portion 67 and the locking receiving portion 51 can be visually confirmed from the front of the cover portion 18 through the locking hole 52 or with a sensor, and thus it is not necessary to perform special processing on the movable plate 15 and the front stopper 16.

[0098] In addition, the hanging portion 48 is locked in the hanging receiving portion 92, and thus the movable plate 15 is moved from the fitted position to the initial position in conjunction with the detachment of the female housing 81 from the cover portion 18, and thus it is also not necessary to independently perform the movement operation of the movable plate 15 to the initial position.

[0099] Further, the hanging portion 48 is disposed on the lower side of the movable plate 15, and the locking receiving portion 51 is disposed on the upper side of the movable plate 15, and thus the hanging portion 48 and the locking receiving portion 51 can be formed with high degrees of freedom, respectively. In addition, the hanging portion 48 and the locking receiving portion 51 are disposed in pairs in the width direction in the movable plate 15, and thus the movable plate 15 and the front stopper 16 can be smoothly moved to the initial position and the standby position, respectively, while maintaining balance.

[0100] [Other Embodiments of the Present Disclosure]

[0101] It should be considered that the present embodiment 1 is illustrative in all aspects, and is not limiting.

[0102] In the case of the above-described embodiment 1, the front stopper has the restriction portion for coaxiality. However, as another embodiment, it can also be a structure in which the restriction portion for coaxiality is omitted from the front stopper, and the front stopper does not secondarily stop the coaxial terminal. Incidentally, it can also be a structure in which the male housing does not accommodate the coaxial terminal.

[0103] In the case of the above-described embodiment 1, it is a structure in which the movable plate moves from the fitting position to the initial position in conjunction with the disengagement of the female housing. However, as another embodiment, it can also be a structure in which the movable plate moves from the fitting position to the initial position without conjunction with the female housing. In this case, it is also sufficient to be a structure in which the front stopper also moves from the stop position to the standby position when the movable plate moves from the fitting position to the initial position.

[0104] In the case of the above-described embodiment 1, the front stopper is partially formed so as to cover a part of the rear surface side of the plate main body of the movable plate. However, as another embodiment, the front stopper can also be formed in a plate shape so as to cover the rear surface side of the plate main body of the movable plate as a whole.
