Description

Technical Field

[0001] The present disclosure relates to connectors. Background Art

[0002] The connector disclosed in Patent Document 1 has a female housing and a male housing that can be engaged and disengaged with each other. The male housing has a cover. Inside the cover, a movable plate that can move between an initial position and an engaged position is assembled. The movable plate plays a role of protecting the tab of the male terminal part in the initial position.

[0003] The female housing has cavity towers that are paired in the width direction. Each cavity tower has a cavity for accommodating female terminal parts. An entry space is formed between the cavity towers that are paired in the width direction. The movable plate has an elastic locking piece that protrudes into the entry space. The elastic locking piece is locked in the male housing at the initial position, restricting the movable plate from moving to the mating position. The inner side surfaces facing each other between the cavity towers (the side facing the entry space) are formed with a release portion for releasing the locking state between the elastic locking piece and the male housing, which is used to release the locking state between the elastic locking piece and the male housing. When the release portion has locked the elastic locking piece, the female housing is detached from the male housing. Therefore, the movable plate can return to the initial position.

[0004] Patent document 2 discloses a movable plate having ribs that can enter the bending space of the lance. The ribs restrict the bending movement of the lance, thereby maintaining the state where the sub-connector is locked by the lance. Patent document 3 discloses a movable plate that also functions as a front end retainer.

[0005] In Patent Documents 1 to 3, since the movable plate has multiple functions, the structure of the connector can be simplified as a whole, which helps to achieve miniaturization of the connector. Prior art literature Patent Literature

DETAILED DESCRIPTION

[0012] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be described by way of examples. The connector of the present disclosure, (1) A device comprising a second connector and a first connector which can be engaged with and disengaged from each other, the first connector comprising a cover, a movable plate arranged inside the cover, and a first terminal including a front end portion protruding into the cover, the second connector comprising a second housing fitted inside the cover and a second terminal accommodated in the second housing, the movable plate being arranged to be movable between an engaged position located at an inner side and an initial position located away from the inner side to an open side relative to the cover, the front end portion of the first terminal being protected by the movable plate at the initial position and connected to the second terminal at the engaged position, the second housing comprising a second lance-shaped portion which is flexibly deformable to prevent the second terminal from being disengaged, a flexing space which allows the second lance-shaped portion to flex, and a locking portion provided in the flexing space, and the movable plate comprising a plate body through which the first terminal passes and a protruding portion protruding from the plate body, the protruding portion comprising a locked portion which is arranged in the flexing space at the engaged position and can be locked in the locking portion when moving from the engaged position to the initial position.

[0013] The movable plate has a function of protecting the front end of the first terminal (protection function). In addition, the protrusion of the movable plate has a function of pulling the movable plate back from the fitting position to the initial position (pulling back function) and a function of being arranged in the bending space to suppress the bending action of the second lance (stopping function). Therefore, compared with setting each function (protection function, pulling back function, stopping function) at different positions of the movable plate, the structure of the movable plate can be simplified, which helps to achieve miniaturization of the movable plate. In particular, since the protrusion is arranged in the bending space of the second lance, the second shell will not be enlarged.

[0014] (2) In the connector described in (1) above, the protrusion preferably has a plate-shaped protruding body with the plate width oriented in a direction intersecting the bending direction of the second lance-shaped portion, and the protruding body is formed to be able to bend and deform in the plate width direction due to interference between the locked portion and the locking portion.

[0015] Since the protruding body is bent and deformed in the plate width direction due to the interference between the locked portion and the locking portion, the locked state of the locked portion and the locking portion in the fitting position can be well maintained. In addition, since the protruding portion is bent and deformed in the plate width direction which is a direction intersecting the bending direction of the second lance-shaped portion, it is not easy to bend and deform in the bending direction of the second lance-shaped portion, and the bending action of the second lance-shaped portion can be well suppressed.

[0016] (3) In the connector described in (2) above, the protruding body preferably has a deflection allowance portion at a middle portion in the board width direction, and the locked portion is shaped to protrude from an end surface of the protruding body in the board width direction.

[0017] Since the protrusion can be bent and deformed in the plate width direction while ensuring the plate width in the left-right direction, it is possible to ensure the strength required for suppressing the bending motion of the second lance.

[0018] (4) In the connector described in (3) above, the protruding body preferably has a solid pressing portion for covering the second lance in the mating position at a position closer to the distal end side than the deflection allowing portion.

[0019] Since the solid pressing portion can contact the second lance, it can play a role in reliably suppressing the bending motion of the second lance.

[0020] (5) In the connector described in any one of (1) to (4) above, the front end surface of the protruding portion is preferably an interference surface capable of interfering with the second lance portion that has been deflected and deformed in the deflection space.

[0021] If the second terminal is not inserted into the second housing to the regular position but stays in the half-insertion position, the second lance will be pushed by the second terminal staying in the half-insertion position and deform in the flexure space. In contrast, according to the structure of (5), the interference surface of the protrusion will interfere with the second lance that has been deformed in the flexure space, thereby stopping the second housing from further engaging. Therefore, it is possible to avoid the second housing engaging into the inside of the cover when the second terminal stays in the half-insertion position.

[0022] [Details of the embodiments of the present disclosure] Specific examples of the present disclosure are described below with reference to the drawings. Note that the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0023] <Implementation Method 1> like Figure 1 and Figure 2As shown in FIG. 1 , the connector 10 of the first embodiment includes a second connector 11 and a first connector 12 that can be engaged with and disengaged from each other. Figure 2 As shown, the second connector 11 has a second housing 13 and a second terminal 14 accommodated in the second housing 13. The first connector 12 has a first housing 15 and a first terminal 16 accommodated in the first housing 15, and a movable plate 17 movably assembled in the first housing 15. In the following description, regarding the front-to-back direction, the surface side of the second connector 11 and the first connector 12 facing each other is the front side, and the up-down direction is the down-down direction. Figure 2 The left-right direction is a direction perpendicular to the front-back direction and the up-down direction, also called the width direction. Figure 3 Symbols X, Y, and Z represent the front side, the right side, and the upper side of the second connector 11, respectively. Figure 5 Symbols X, Y and Z respectively represent the front side, right side and upper side of the first connector 12. These directional references are not necessarily consistent with the directional references when the connector 10 is mounted on a vehicle or the like (not shown). In addition, the middle portion refers to the portion excluding the two end portions and does not mean to be limited to the center.

[0024] (Second connector 11) The second housing 13 is made of synthetic resin, such as Figure 4 As shown, as a cavity that penetrates in the front-to-back direction, there are a plurality of first female storage chambers 18 and a plurality of second female storage chambers 19. The cross section of each first female storage chamber 18 is circular, and is arranged in pairs along the width direction in the left and right middle parts of the second shell 13. The cross section of each second female storage chamber 19 is rectangular, and a plurality of second female storage chambers 19 are neatly arranged and arranged along the width direction and the height direction at the left and right ends of the second shell 13.

[0025] The second housing 13 has a second lance 21 on the upper surface of the inner wall of each female first storage chamber 18. Figure 2 As shown, the second lance 21 has a plate-shaped lance body 23 extending forward from a root 22 of the inner wall of each female first storage chamber 18 (see Figure 3 ) and a locking protrusion 24 protruding downward from the front and rear middle part of the lance body 23. The lance body 23 can be bent and deformed in the vertical direction with the root 22 as a fulcrum.

[0026] The second housing 13 has a pair of left and right bending spaces 25 above each second lance 21, which allow bending of each second lance 21. Each bending space 25 extends in the front-to-back direction and opens at the front surface of the second housing 13. Figure 4 As shown, on the front surface of the second housing 13 , the front surfaces of the second lances 21 are also exposed through the spaces for mold removal that communicate with the flexure spaces 25 .

[0027] like Figure 3 and Figure 4 As shown, the second housing 13 has a pair of left and right stoppers 26 on the side surfaces of the left and right inner sides of the inner wall of each flexure space 25 (the left and right center sides of the second housing 13). Each stopper 26 is arranged one at each flexure space 25. Each stopper 26 is protruding from a wall portion 27 arranged between each flexure space 25. The front surface of each stopper 26 is inclined backward from the front surface of the second housing 13. The rear surface of each stopper 26 is a stopper surface, which is arranged along the left and right direction. The end surface of each stopper 26 extends in the front-to-back direction and is arranged between the front surface and the rear surface.

[0028] like Figure 4 As shown in FIG. 1 , a recess 28 is formed in the left and right middle parts of the upper surface of the second housing 13. The bottom surface of the recess 28 is arranged at a position lower than the left and right ends of the upper surface of the second housing 13. The second housing 13 has a locking arm 29 that is capable of flexural deformation and protrudes from the left and right middle parts of the bottom surface of the recess 28 and extends rearward. The locking arm 29 has the function of locking the first housing 15 and maintaining the second connector 11 and the first connector 12 in a mating state. The locking arm 29 is continuously arranged above the wall portion 27. The left and right ends of the bottom surface of the recess 28 are arranged above each flexure space 25.

[0029] like Figure 4 As shown, the second housing 13 has a pair of left and right through holes 31 between the left and right ends of each female side second storage chamber 19 and the locking arm 29 in the left and right directions. Each through hole 31 penetrates the second housing 13 along the front-back direction. Each through hole 31 is arranged on the left and right outer sides of each bending space 25. A pair of left and right release parts 32 are protrudingly provided on the side surfaces of the left and right inner sides of the inner wall of each through hole 31. As will be described later, each release part 32 has the function of releasing the state in which the movable plate 17 in the initial position is stuck to the first housing 15.

[0030] The second terminal 14 has a circular outer peripheral surface and constitutes a so-called coaxial terminal. Figure 2 and Figure 3 As shown, the second terminal 14 is connected to the end of the coaxial wire 33. The second terminal 14 and the coaxial wire 33 have a shielding layer (not shown) to suppress the influence of noise. A locking recess 34 is formed all around the outer peripheral surface of the second terminal 14. The second terminal 14 is inserted into the female first storage chamber 18 from the rear in a state connected to the coaxial wire 33 ( Figure 3 Only one second terminal 14 is shown.) The locking protrusion 24 of the second lance 21 is engaged and locked in the locking recess 34, so that the second terminal 14 is held in the female first housing chamber 18 so as not to come out.

[0031] A general female terminal (not shown) is inserted into the female second storage chamber 19. The general female terminal is connected to the end of a general electric wire (not shown). The general female terminal and the general electric wire do not have a shielding layer and are smaller than the second terminal 14 and the coaxial wire 33.

[0032] (First Housing 15 and First Terminal 16) The first housing 15 is made of synthetic resin, such as Figure 5 As shown in FIG. 1 , the terminal receiving portion 35 has a square-shaped terminal receiving portion 35 and a square-tube-shaped cover portion 36 protruding forward from the terminal receiving portion 35. The cover portion 36 is one circle larger than the terminal receiving portion 35. Figure 6 As shown, as a cavity penetrating in the front-to-back direction, the terminal storage portion 35 has a plurality of male side first storage chambers 37 and a plurality of male side second storage chambers 38. Each male side first storage chamber 37 is circular and is arranged in pairs in the width direction at the left and right middle parts of the terminal storage portion 35. The cross section of each male side second storage chamber 38 is rectangular, and a plurality of male side second storage chambers 38 are neatly arranged and arranged in the width direction and the height direction at the left and right ends of the terminal storage portion 35. The terminal storage portion 35 has a pair of left and right first lance-shaped portions 39 that can be flexibly deformed on the upper surface of the inner wall of each male side first storage chamber 37.

[0033] The first terminal 16 has a circular outer peripheral surface in cross section similarly to the second terminal 14, and constitutes a so-called coaxial terminal. The first terminal 16 is connected to the coaxial wire 40 (see Figure 4 ) at the end portion. The first terminal 16 and the coaxial wire 40 have a shielding layer (not shown) for suppressing the influence of noise. The first terminal 16 is inserted into the male first storage chamber 37 from the rear while being connected to the coaxial wire 40, and is locked in the first lance 39, and is held in the male first storage chamber 37 so as not to be removed. When the first terminal 16 is locked in the first lance 39, the front end of the first terminal 16 is configured to protrude into the interior of the cover 36. Figure 2 As shown, when the second connector 11 and the first connector 12 are mated, the front end portions of the second terminals 14 are embedded in the front end portions of the first terminals 16, and the second terminals 14 and the first terminals 16 are connected to each other.

[0034] A general male terminal (not shown) is inserted into the male-side second storage chamber 38. The general male terminal is connected to the terminal end of a general electric wire (not shown). The general male terminal and the general electric wire do not have a shielding layer and are smaller than the first terminal 16 and the coaxial wire 40. Like the first terminal 16, the front end of the general male terminal is configured to protrude into the inside of the cover 36. When the second connector 11 and the first connector 12 are mated, the general male terminal is connected to the general female terminal.

[0035] like Figure 6As shown, the first shell 15 has a pair of left and right retaining portions 41 protruding forward (inside the cover portion 36) at positions on the left and right outer sides and above each first lance-shaped portion 39 on the front surface of the terminal receiving portion 35. The retaining portion 41 has a plate-shaped retaining body 42 with the plate surface facing the left and right directions, and a forward limiting portion 43 and a backward limiting portion 44 of the plate surface protruding from the left and right inner sides of the retaining body 42 (the left and right center sides of the first shell 15). The backward limiting portion 44 is provided in a pair at the upper and lower ends of the retaining portion 41. The forward limiting portion 43 is configured to be located in front of each backward limiting portion 44 and between each backward limiting portion 44 in the up and down direction. As shown Fig. 9 As shown, the movable plate 17 at the initial position is held between the forward limiting portion 43 and the backward limiting portion 44 of each holding portion 41. The forward limiting portion 43 limits the forward movement of the movable plate 17. The backward limiting portion 44 limits the backward movement of the movable plate 17. When the second connector 11 and the first connector 12 are mated, each holding portion 41 is inserted into each through hole 31 of the second housing 13.

[0036] like Figure 6 As shown in FIG. 1 , the cover 36 has a locking portion 45 protruding downward (inside the cover 36) from the left and right middle portions of the upper wall. The second housing 13 is fitted into the inside of the cover 36. When the second housing 13 is fitted into the inside of the cover 36 at a regular depth, the locking portion 45 is locked to the locking arm 29. The cover 36 has a pair of left and right guide ribs 46 protruding downward (inside the cover 36) at the left and right sides of the upper wall across the locking portion 45.

[0037] (Active plate 17) The movable plate 17 is made of synthetic resin, such as Figure 5 As shown in FIG. 1 , the plate body 47 has a plate-shaped plate surface facing the front-rear direction. The plate body 47 is inserted into the cover portion 36. The outer edge of the plate body 47 has a shape corresponding to the inner surface of the cover portion 36 and is arranged on the inner surface of the cover portion 36 along the circumferential direction. Figure 7 As shown in FIG. 1 , a recess 48 is formed in the left and right middle parts of the upper edge of the plate body 47. The bottom surface of the recess 48 is arranged at a position slightly lower than the left and right ends of the upper edge of the plate body 47. When the plate body 47 is inserted into the cover 36, the recess 48 is provided with each guide rib 46 (see FIG. Fig. 9 ).

[0038] The plate body 47 has a pair of left and right through holes 49 that penetrate the plate thickness direction at positions on both sides of the recessed portion 48. Each through hole 49 is a rectangular shape that is long in the vertical direction. Fig. 9 As shown, the holding portion 41 is inserted into each through hole 49 .

[0039] like Figure 7As shown in FIG. 1 , the plate body 47 has a plurality of insertion holes 51 and 52 penetrating in the plate thickness direction (front-back direction). Each insertion hole includes a first circular insertion hole 51 arranged in pairs in the width direction at the left and right middle parts of the plate body 47 and a plurality of second rectangular insertion holes 52 arranged in a row in the width direction and the height direction at the left and right ends of the plate body 47. Figure 5 As shown, the front end of each first terminal 16 is inserted into each first insertion hole 51 ( Figure 5 Only one first terminal 16 is shown.) The front end portion of each general male terminal is inserted into each second insertion hole 52 in a positioned state.

[0040] like Figure 5 and Figure 7 As shown, the movable plate 17 has a pair of left and right protection parts 53 protruding forward from the opening edge of each first insertion hole 51 on the front surface of the plate body 47. Each protection part 53 is in the shape of a plate with a circular arc cross section extending along the left and right sides at the lower part of the opening edge of each first insertion hole 51, and is configured to cover the front end of each first terminal 16 from the left and right sides.

[0041] like Figure 7 As shown in FIG. 1 , the movable plate 17 has a pair of left and right protrusions 54 protruding forward from the upper edge of the opening of each first insertion hole 51 on the front surface of the plate body 47. Each protrusion 54 is arranged above each protection portion 53 and on the left and right inner sides of each through hole 49 (on the left and right center sides of the movable plate 17) in the movable plate 17. Each protrusion 54 is in the shape of a plate with the plate surface facing the up-down direction. Figure 7 and Figure 8 As shown, each protrusion 54 has a protrusion body 55 whose outer edge is rectangular when viewed from above. The protrusion body 55 has a deflection allowing portion 56 that penetrates along the plate thickness direction (up and down direction) and extends in the front and rear direction in the middle part on the left and right sides. The rear end of the deflection allowing portion 56 opens on the rear surface of the plate body 47. The front part of the protrusion body 55 is a solid pushing portion 57 with a constant up and down thickness as a whole. The front end of the deflection allowing portion 56 is closed by the pushing portion 57. The front end surface of the pushing portion 57 constitutes the front end surface of the protrusion 54 in the protruding direction and is arranged in front of each protective portion 53. The front end surface of the pushing portion 57 is configured as an interference surface 58 along the left and right direction. As will be described later, the interference surface 58 can interfere with the second lance 21 that has been deflected and deformed in the deflection space 25 (refer to Fig.10 ).

[0042] like Figure 7 and Figure 8As shown in FIG. 1 , each protrusion 54 has a latched portion 59 that protrudes from the left and right inner end surfaces of the protrusion body 55 (the opposing surfaces of the protrusion body 55 of each protrusion 54 facing each other) to the left and right inner sides. The latched portion 59 is arranged at the front and rear middle portion of the protrusion 54, which is located at a position overlapping the deflection allowing portion 56 in the left and right direction. Figure 1 and Figure 8 As shown, the front surface of each locked portion 59 is inclined rearward. The rear surface of each locked portion 59 is arranged along the left-right direction. The end surface of each locked portion 59 is arranged to extend in the front-rear direction between the front surface and the rear surface.

[0043] <Function of connector 10> The movable plate 17 is assembled so as to be movable in the forward and backward directions between the initial position and the fitting position relative to the cover portion 36. Figure 1 As shown, the movable plate 17 is located on the inner side of the cover portion 36, and the plate body 47 is configured to abut or approach the front surface of the terminal receiving portion 35. Fig. 9 As shown, the movable plate 17 is located away from the inner side of the cover portion 36 to the opening side, and the plate body 47 is arranged to be separated from the terminal receiving portion 35 .

[0044] like Fig. 9 As shown, in the initial position, the retaining body 42 of the retaining portion 41 is inserted into the through hole 49 of the plate body 47. Here, the forward limiting portion 43 is arranged to face the front surface of the plate body 47 so as to be in contact with it. This limits the movement of the movable plate 17 toward the opening side (front side) of the cover portion 36. In addition, in the initial position, the backward limiting portion 44 is arranged to face the rear surface of the plate body 47 so as to be in contact with it. This limits the movement of the movable plate 17 toward the inner side (rear side) of the cover portion 36. As shown in FIG. Figure 5 As shown, the front end portion of the first terminal 16 passes through the first insertion hole 51 of the plate body 47 , and the front end surface is exposed on the front surface side of the plate body 47 .

[0045] When the second connector 11 and the first connector 12 begin to be mated, each protrusion 54 is mated into each flexure space 25 of the second housing 13, and the latched portion 59 of each protrusion 54 interferes with each latching portion 26. As a result, the protruding body 55 of each protrusion 54 is deformed in the width direction that narrows the flexure allowance portion 56. As the second connector 11 and the first connector 12 are mated, each latching portion 26 passes over each latched portion 59, each protruding body 55 elastically recovers, and each latching portion 26 is arranged to face each other in a manner that allows it to contact the rear surface (rear surface when viewed from the first connector 12) of each latched portion 59.

[0046] During the bending and deformation of each protruding body 55, the front end of each holding portion 41 enters each through hole 31 of the second housing 13, and the release portion 32 interferes with the forward limiting portion 43. Therefore, the holding body 42 of each holding portion 41 is bent and deformed to the left and right sides in the through hole 49 with the front surface of the terminal receiving portion 35 as a fulcrum, and the locking of the plate body 47 by the retreat limiting portion 44 is released. Thereafter, the front surface of the second housing 13 (the front surface when viewed from the second connector 11, including the front surface of the wall portion 27) abuts against the front surface of the plate body 47 (the front surface when viewed from the first connector 12). At the same time as the second housing 13 abuts against the plate body 47 or slightly before the abutment, each protruding body 55 elastically recovers. Due to further mating, the movable plate 17 is pushed back to the mating position by the second housing 13. In the process of the movable plate 17 retreating, the holding body 42 of each holding portion 41 elastically recovers.

[0047] like Figure 1 As shown in the figure, when the movable plate 17 reaches the mating position, the plate body 47 is configured to be sandwiched between the front surface of the terminal receiving portion 35 (the front surface when viewed from the first connector 12) and the front surface of the second housing 13 (the front surface when viewed from the second connector 11). At the mating position, the locking portion 45 is locked by the locking arm 29, and the second connector 11 and the first connector 12 are maintained in a mating state. In addition, at the mating position, the front ends of the second terminal 14 and the first terminal 16 are mated and connected to each other.

[0048] like Figure 2 As shown, when the pressing portion 57 of the protrusion 54 has entered the flexure space 25, it faces the upper surface of the front end portion (the portion in front of the locking protrusion 24) of the lance body 23 of the second lance 21 in a manner capable of contacting, thereby suppressing the displacement of the second lance 21 into the flexure space 25. Therefore, the locking protrusion 24 of the second lance 21 is fitted into the locking recess 34, and the second terminal 14 is maintained in a locked state.

[0049] On the other hand, if the second terminal 14 is not inserted to the proper depth in the female first receiving chamber 18 and stays at the half-insertion position, as shown in FIG. Fig.10 As shown, the locking protrusion 24 will pass over the outer peripheral surface of the second terminal, and the lance body 23 of the second lance 21 will be arranged in the bending space 25 to protrude obliquely upward. In this way, when the second connector 11 and the first connector 12 begin to be mated with each other in a state where the second terminal 14 stays in the half-inserted position, the interference surface 58 of the protrusion 54 will hit the front end surface of the lance body 23, and the second connector 11 and the first connector 12 will stop further mating. Therefore, it is possible to avoid the situation where the second connector 11 and the first connector 12 are mated with each other while the second terminal 14 stays in the half-inserted position in the female first storage chamber 18.

[0050] Furthermore, if the second connector 11 is intended to be mated with the first connector 12 by tilting from the regular mating posture to an irregular posture, the front surface of the second housing 13 (the front surface when viewed from the second connector 11) will interfere with the interference surface 58 of the protrusion 54. Since the second housing 13 interferes with the interference surface 58 of the protrusion 54, further mating of the second housing 13 in the irregular posture will be stopped. As a result, it is possible to avoid the occurrence of a situation where the second connector 11 and the first connector 12 are not tightly mated.

[0051] When the second connector 11 and the first connector 12 in the mating state are to be separated due to maintenance or the like, the locking of the lock arm 29 and the lock portion 45 is released, and the second housing 13 is moved in the disengagement direction from the inside of the cover portion 36. Figure 1 In the state shown, as the second housing 13 moves in the disengaging direction, the locking portions 26 hook and press the locked portions 59 from the rear (the rear when viewed from the first connector 12), so that the movable plate 17 moves in the disengaging direction together with the second housing 13.

[0052] During the movement of the movable plate 17 to the initial position, each retreat limiting portion 44 slides on the inner surface of each through hole 31, and the retaining body 42 of each retaining portion 41 is bent and deformed to the left and right outer sides. When the movable plate 17 reaches the initial position, the retaining body 42 of each retaining portion 41 is elastically restored, and the plate body 47 is configured to be sandwiched between the forward limiting portion 43 and the retreat limiting portion 44 again. Therefore, the movable plate 17 is configured to be maintained in the initial position and the movement is restricted. In addition, when the second shell 13 is moved in the disengagement direction, on the one hand, the plate body 47 is blocked by the forward limiting portion 43, and on the other hand, as the protruding body 55 of each protruding portion 54 is bent and deformed, each locking portion 26 releases the blocking with each locked portion 59. Therefore, the movable plate 17 can be left in the initial position and the second shell 13 can be separated from the cover portion 36.

[0053] As described above, the movable plate 17 of the first embodiment is configured to be movable between the mating position located at the inner side and the initial position located away from the inner side to the opening side relative to the cover portion 36. The front end of the first terminal 16 is protected by the movable plate 17 at the initial position, and is connected to the second terminal 14 at the mating position. The second housing 13 has a second lance 21 that is flexible and deformable to prevent the second terminal 14 from coming out, a flexing space 25 that allows the second lance 21 to flex, and a stopper 26 provided in the flexing space 25. In addition, the movable plate 17 has a plate body 47 through which the first terminal 16 passes, and a protrusion 54 that protrudes from the plate body 47. The protrusion 54 has a stopper 59 that is arranged in the flexing space 25 at the mating position and can be stopped in the stopper 26 when moving from the mating position to the initial position.

[0054] The movable plate 17 has a function of protecting the front end of the first terminal 16 in the initial position (protection function). In addition, the protrusion 54 of the movable plate 17 has a function of pulling the movable plate 17 back from the mating position to the initial position (pull-back function) and a function of being arranged in the flexure space 25 to limit the flexure action of the second lance 21 (stop function). Therefore, compared with setting each function (protection function, pull-back function, stop function) at different positions of the movable plate 17, the structure of the movable plate 17 can be simplified, which helps to achieve the miniaturization of the locking mechanism of the movable plate 17. In particular, since the protrusion 54 is arranged in the flexure space 25 of the second lance 21, the second housing 13 will not be enlarged. As a result, the connector 10 of the first embodiment can set the pull-back structure of the movable plate 17 without increasing the space.

[0055] The protrusion 54 has a plate-shaped protrusion body 55 with the plate width oriented in a direction intersecting the bending direction of the second lance 21, and the protrusion body 55 is formed so as to be able to bend and deform in the plate width direction by the interference of the locked portion 59 and the locking portion 26. Since the protrusion 54 is bent and deformed in the plate width direction, which is a direction intersecting the bending direction of the second lance 21, it is possible to form a structure that is not easily bent and deformed in the bending direction of the second lance 21, and the bending action of the second lance 21 can be effectively suppressed.

[0056] In addition, the protruding body 55 has a bending allowance portion 56 in the left and right middle portions, and the locked portion 59 is in a shape protruding from the left and right end surfaces of the protruding body 55. Therefore, since the protruding portion 54 can be bent and deformed in the plate width direction while ensuring the plate width in the left and right directions, the strength required for suppressing the bending action of the second lance 21 can be ensured.

[0057] The protruding body 55 has a solid pressing portion 57 for covering the second lance 21 in the mating position at the tip of the deflection allowing portion 56. The solid pressing portion 57 can contact the second lance 21, thereby reliably suppressing the deflection of the second lance 21.

[0058] Furthermore, the front end surface of the protrusion 54 is an interference surface that can interfere with the second lance 21 that has been bent and deformed in the flexure space 25. If the second terminal 14 stays at the half-insertion position in the second housing 13, when the second lance 21 is pushed by the second terminal 14 and is bent and deformed in the flexure space 25, the interference surface of the protrusion 54 will interfere with the second lance 21 that has been bent and deformed in the flexure space 25, thereby stopping the second housing 13 from further fitting. Therefore, it is possible to avoid the situation in which the second housing is fitted into the inside of the cover when the second terminal 14 stays at the half-insertion position in the second housing 13.

[0059] <Other embodiments of the present disclosure> The above-described first embodiment disclosed this time should be considered in all respects as illustrative and non-restrictive. In the first embodiment, the deflection allowance 56 is shaped to penetrate the left and right middle portions of the protrusion body 55 in the plate thickness direction. In contrast, according to other embodiments, the deflection allowance may be shaped to be thinner than the left and right end portions so as to be able to bend and deform. In the first embodiment, the first terminal 16 is a coaxial terminal having a shield layer. In contrast, according to another embodiment, the first terminal may be a general male terminal without a shield layer. In the first embodiment, the terminals of the first connector 12 are composed of the first terminals 16 as coaxial terminals and general male terminals, and the terminals of the second connector 11 are composed of the second terminals 14 as coaxial terminals and general female terminals. In contrast, according to other embodiments, the terminals of the first connector may be composed of only the first terminals, and the terminals of the second connector may be composed of only the second terminals. In the first embodiment, the movable plate 17 is provided with two protrusions 54, and each protrusion 54 is provided with a locked portion 59. In contrast, according to other embodiments, the movable plate may be provided with one or more protrusions, and each protrusion may be provided with a plurality of locked portions.
