Description

[Technical field]

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

[0002] The connector disclosed in Patent Document 1 includes a female housing and a male housing that can be mated or separated from each other. The male housing has a hood portion. A moving plate that can move between an initial position and a mating position is attached inside the hood portion. The moving plate has the function of protecting the tabs of the male terminal fittings in the initial position.

[0003] The female housing has a pair of cavity towers in the width direction. Each cavity tower has a cavity for accommodating a female terminal fitting. An entry space is formed between the pair of cavity towers in the width direction. The moving plate has an elastic locking piece that protrudes into the entry space. The elastic locking piece is locked to the male housing at an initial position and restricts the movement of the moving plate to the mating position. A release portion that releases the lock between the elastic locking piece and the male housing is formed on the inner surface (the side facing the entry space) where the cavity towers face each other. With the release portion locking the elastic locking piece, the female housing is released from the male housing. This allows the moving plate to return to the initial position.

[0004] Patent Document 2 discloses a moving plate having a rib that can enter the deflection space of the lance. The deflection of the lance is restricted by the rib, so that the lance maintains the state of engaging the sub-connector. Patent Document 3 discloses a moving plate that also functions as a front holder.

[0005] In the cases of Patent Documents 1 to 3, the moving plate has a variety of functions, which allows the overall structure of the connector to be simplified and contributes to miniaturization of the connector. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2016-12472 A [Patent Document 2] JP 2011-44386 A [Patent Document 3] JP 2003-282188 A Summary of the Invention [Problem to be solved by the invention]

[0007] As shown in Patent Document 1, a structure for returning a moving plate from a mating position to an initial position (hereinafter referred to as a "return structure") is known, but from the viewpoint of space efficiency, there has been a demand to add a function different from that of Patent Document 1 to the moving plate return structure. In that case, there has been a concern that the connector will become larger.

[0008] In view of the above, an object of the present disclosure is to provide a connector in which a moving plate pull-back structure can be provided that is multifunctional and does not require a large amount of space. [Means for solving the problem]

[0009] The connector of the present disclosure comprises a second connector and a first connector which are capable of being engaged with and disengaged from each other, the first connector having a hood portion, a moving plate disposed inside the hood portion, and a first terminal including a tip portion protruding into the hood portion, the second connector having a second housing engaged inside the hood portion, and a second terminal accommodated in the second housing, the moving plate being disposed to be movable between a mating position located on the rear side of the hood portion and an initial position located away from the rear side toward an opening side, and the tip portion of the first terminal is The second housing is protected by the moving plate in the initial position and is connected to the second terminal in the mating position, and has a flexibly deformable second lance that prevents the second terminal from coming loose, a flexure space that allows the second lance to flex, and a locking portion arranged in the flexure space, and further, the moving plate has a plate main body through which the first terminal passes and a protrusion protruding from the plate main body, and the protrusion is arranged in the flexure space in the mating position and has an engaged portion that can be engaged with the locking portion when moving from the mating position to the initial position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A first connector and a second connector which are mutually engageable and disengageable, the first connector having a hood portion, a moving plate disposed inside the hood portion, and a first terminal including a tip portion protruding into the hood portion, the second connector having a second housing fitted inside the hood portion, and a second terminal accommodated in the second housing, the moving plate is disposed to be movable between a mating position located on the rear side with respect to the hood portion and an initial position located away from the rear side toward an opening side, and the tip portion of the first terminal is disposed in the initial position. the second housing is protected by the moving plate in the mating position and is connected to the second terminal in the mating position, the second housing has a flexibly deformable second lance that prevents the second terminal from coming out, a flexure space that allows the second lance to flex, and a locking portion arranged in the flexure space, and further, the moving plate has a plate main body through which the first terminal passes and a protrusion protruding from the plate main body, the protrusion being arranged in the flexure space in the mating position and having an engaged portion that can be engaged with the locking portion when moving from the mating position to the initial position.

[0013] The moving plate has a function (protective function) of protecting the tip of the first terminal. In addition, the protruding portion of the moving plate has a function (pulling back function) of pulling the moving plate from the mating position to the initial position, and a function (retainer function) of being disposed in the deflection space and suppressing the deflection action of the second lance. This makes it possible to simplify the structure of the moving plate and reduce the size of the moving plate compared to when each function (protective function, pulling back function, retainer function) is provided in a separate part of the moving plate. In particular, because the protruding portion is disposed in the deflection space of the second lance, the second housing does not become large.

[0014] (2) In the connector described in (1) above, it is preferable that the protrusion has a plate-shaped protrusion body with its plate width oriented in a direction intersecting the bending direction of the second lance, and that the protrusion body is formed so as to be able to bend and deform in the plate width direction due to interference between the engaged portion and the engaging portion.

[0015] The interference between the locked portion and the locking portion causes the protruding body to flex in the plate width direction, so that the locked state between the locked portion and the locking portion can be well maintained at the mating position. Also, because the protruding portion flexes in the plate width direction, which is a direction intersecting the bending direction of the second lance, it is difficult for the protruding portion to flex in the bending direction of the second lance, and the function of suppressing the bending action of the second lance can be well performed.

[0016] (3) In the connector described in (2) above, it is preferable that the protruding body has a deflection-allowing portion in the middle portion in the plate width direction, and the engaging portion is shaped to protrude from the end face of the protruding body in the plate width direction.

[0017] Since the protrusion is capable of bending and deforming in the plate width direction while ensuring the plate width in the left-right direction, it is possible to ensure the strength required to suppress bending of the second lance.

[0018] (4) In the connector described above in (3), it is preferable that the protruding body has a solid pressing portion on the tip side of the deflection-allowing portion, the solid pressing portion covering the second lance in the mating position.

[0019] Since the solid pressing portion can come into contact with the second lance, the function of suppressing the deflection movement of the second lance can be reliably performed.

[0020] (5) In the connector described in any one of (1) to (4) above, it is preferable that a tip surface of the protrusion is an interference surface that can interfere with the second lance that is deflected and deformed in the deflection space.

[0021] If the second terminal is not inserted to the correct position in the second housing and remains in a half-inserted position, the second lance is pressed by the second terminal remaining in the half-inserted position and is deflected and deformed into the deflection space. In contrast, according to the configuration of (5) above, the interference surface of the protrusion interferes with the second lance that has deflected and deformed into the deflection space, stopping further fitting of the second housing. Therefore, it is possible to prevent the second housing from being fitted into the inside of the hood portion when the second terminal remains in the half-inserted position in the second housing.

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

[0023] <Embodiment 1> As shown in Figs. 1 and 2, the connector 10 of the first embodiment includes a second connector 11 and a first connector 12 that can be fitted and detached to each other. As shown in Fig. 2, the second connector 11 has a second housing 13 and a second terminal 14 housed in the second housing 13. The first connector 12 has a first housing 15, a first terminal 16 housed in the first housing 15, and a moving plate 17 movably assembled to the first housing 15. In the following description, the front side is the surface side where the second connector 11 and the first connector 12 face each other. The up-down direction is based on the up-down direction in Fig. 2 and may be referred to as the height direction. The left-right direction is a direction perpendicular to the up-down direction and the up-down direction and may be referred to as the width direction. The symbols X, Y, and Z in Fig. 3 respectively represent the front side, right side, and upper side of the second connector 11. 5, the symbols X, Y, and Z respectively represent the front side, right side, and upper side of the first connector 12. The reference directions for these directions do not necessarily coincide with the reference directions when the connector 10 is mounted on a vehicle or the like (not shown). In addition, the intermediate portion refers to a portion excluding both ends, and is not limited to the center.

[0024] (Second connector 11) The second housing 13 is made of synthetic resin and has a plurality of female-side first storage chambers 18 and a plurality of female-side second storage chambers 19 as cavities penetrating in the front-rear direction, as shown in Fig. 4. Each of the female-side first storage chambers 18 has a circular cross section and is arranged side by side in pairs in the width direction at the left-right intermediate portion of the second housing 13. Each of the female-side second storage chambers 19 has a rectangular cross section and is arranged in large numbers in a row in the width direction and height direction at both left and right ends of the second housing 13.

[0025] The second housing 13 has a second lance 21 on the upper surface of the inner wall of each female-side first housing chamber 18. As shown in Fig. 2, the second lance 21 has a plate-shaped lance body 23 (see Fig. 3) extending forward from a base portion 22 of the inner wall of each female-side first housing chamber 18, and a locking projection 24 projecting downward from a front-to-rear intermediate portion of the lance body 23. The lance body 23 is capable of bending and deforming in the vertical direction with the base portion 22 as a fulcrum.

[0026] The second housing 13 has a pair of left and right flexure spaces 25 above each second lance 21 to allow the second lance 21 to flex. Each flexure space 25 extends in the front-rear direction and opens to the front surface of the second housing 13. As shown in Fig. 4, the front surfaces of each second lance 21 are also exposed to the front surface of the second housing 13 via spaces for punching that communicate with each flexure space 25.

[0027] As shown in Figs. 3 and 4, the second housing 13 has a pair of left and right locking portions 26 on the left and right inner side surfaces (left and right center sides of the second housing 13) of the inner wall of each deflection space 25. Each locking portion 26 is disposed in each deflection space 25. Each locking portion 26 protrudes from a wall portion 27 disposed between each deflection space 25. The front surface of each locking portion 26 is inclined rearward from the front surface of the second housing 13. The rear surface of each locking portion 26 is a locking surface and is disposed along the left-right direction. The end surface of each locking portion 26 is disposed so as to extend in the front-rear direction between the front and rear surfaces.

[0028] As shown in FIG. 4, a recess 28 is formed in the left-right middle part of the upper surface of the second housing 13. The bottom surface of the recess 28 is located at a position one step lower than both left and right ends of the upper surface of the second housing 13. The second housing 13 has a flexibly deformable lock arm 29 that protrudes from the left-right middle part of the bottom surface of the recess 28 and extends rearward. The lock arm 29 has a function of locking the first housing 15 and holding the second connector 11 and the first connector 12 in a mated state. The lock arm 29 is located continuously above the wall portion 27. Both left and right ends of the bottom surface of the recess 28 are located above each of the flex spaces 25.

[0029] As shown in Fig. 4, the second housing 13 has a pair of left and right through holes 31 between the left and right ends having the female-side second accommodation chambers 19 and the lock arm 29 in the left-right direction. Each through hole 31 penetrates the second housing 13 in the front-rear direction. Each through hole 31 is disposed on the left and right outer sides of each deflection space 25. A pair of left and right release portions 32 protrude from the left and right inner side surfaces of the inner wall of each through hole 31. Each release portion 32 has a function of releasing the state in which the moving plate 17 in the initial position is locked to the first housing 15, as will be described later.

[0030] The second terminal 14 has a circular outer peripheral surface and is configured as a so-called coaxial terminal. As shown in Figs. 2 and 3, the second terminal 14 is connected to the end portion of the coaxial electric wire 33. The second terminal 14 and the coaxial electric wire 33 have a shielding layer (not shown) for suppressing the influence of noise. A locking recess 34 is formed on the outer peripheral surface of the second terminal 14 over the entire circumference. The second terminal 14 is inserted into the female-side first accommodating chamber 18 from the rear in a state in which it is connected to the coaxial electric wire 33 (only one second terminal 14 is shown in Fig. 3). The locking projection 24 of the second lance 21 fits into and is locked in the locking recess 34, so that the second terminal 14 is held in the female-side first accommodating chamber 18 in a non-dislodging state.

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

[0032] (First housing 15 and first terminal 16) First housing 15 is made of synthetic resin, and has terminal accommodating portion 35 in the shape of a square block and hood portion 36 in the shape of a square tube protruding forward from terminal accommodating portion 35, as shown in FIG. 5. Hood portion 36 is formed to be slightly larger than terminal accommodating portion 35. As shown in FIG. 6, terminal accommodating portion 35 has a plurality of male first accommodating chambers 37 and a plurality of male second accommodating chambers 38 as cavities penetrating in the front-rear direction. Each male first accommodating chamber 37 has a circular shape and is arranged in a pair in the width direction at the left and right intermediate portion of terminal accommodating portion 35. Each male second accommodating chamber 38 has a rectangular cross section and is arranged in a large number in the width direction and height direction at both left and right ends of terminal accommodating portion 35. Terminal accommodating portion 35 has a pair of left and right first lances 39 that can be deformed flexibly on the upper surface of the inner wall of each male first accommodating chamber 37.

[0033] The first terminal 16, like the second terminal 14, has an outer peripheral surface with a circular cross section, and is configured as a so-called coaxial terminal. The first terminal 16 is connected to the end portion of the coaxial electric wire 40 (see FIG. 4). The first terminal 16 and the coaxial electric wire 40 have a shielding layer (not shown) that suppresses the influence of noise. The first terminal 16, in a state where it is connected to the coaxial electric wire 40, is inserted from the rear into the male side first housing chamber 37, and is locked by the first lance 39 and held in the male side first housing chamber 37 in a non-removable state. In a state where the first terminal 16 is locked by the first lance 39, the tip portion of the first terminal 16 is disposed protruding inside the hood portion 36. As shown in FIG. 2, when the second connector 11 and the first connector 12 are mated, the tip portion of the second terminal 14 fits into the tip portion of the first terminal 16, and the second terminal 14 and the first terminal 16 are connected to each other.

[0034] A general male terminal (not shown) is inserted into the male-side second housing chamber 38. The general male terminal is connected to an end portion 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 tip portion of the general male terminal is disposed so as to protrude inside the hood portion 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] As shown in FIG. 6, the first housing 15 has a pair of left and right holding parts 41 that protrude forward (inside the hood part 36) from positions on the left and right outer sides and above each first lance 39 on the front surface of the terminal accommodating part 35. The holding part 41 has a plate-shaped holding body 42 with a plate surface facing in the left and right direction, and an advancement restricting part 43 and a retreat restricting part 44 that protrude from the plate surface on the left and right inner sides (the left and right center side of the first housing 15) of the holding body 42. The retreat restricting parts 44 are provided in pairs at both upper and lower ends of the holding part 41. The advancement restricting part 43 is disposed forward of each retreat restricting part 44 and between each retreat restricting part 44 in the up-down direction. As shown in FIG. 9, the moving plate 17 in the initial position is sandwiched and held between the advancement restricting part 43 and the retreat restricting part 44 of each holding part 41. The advancement restricting part 43 restricts the advancement of the moving plate 17. The retreat restricting part 44 restricts the retreat of the moving plate 17. When the second connector 11 and the first connector 12 are mated, the holding portions 41 are inserted into the respective through holes 31 of the second housing 13 .

[0036] As shown in Fig. 6, the hood portion 36 has a lock portion 45 that protrudes downward (into the inside of the hood portion 36) from the left-right middle portion of the upper wall. The second housing 13 is fitted into the inside of the hood portion 36. When the second housing 13 is fitted into the inside of the hood portion 36 to the correct depth, the lock portion 45 is engaged with the lock arm 29. The hood portion 36 has a pair of left and right guide ribs 46 that protrude downward (inside the hood portion 36) from left and right positions on either side of the lock portion 45 on the upper wall.

[0037] (Moving Plate 17) The moving plate 17 is made of synthetic resin, and has a plate-shaped plate body 47 with its plate surface facing the front-rear direction as shown in FIG. 5. The plate body 47 is inserted into the inside of the hood portion 36. The outer edge of the plate body 47 has a shape corresponding to the inner surface of the hood portion 36, and is arranged along the circumferential direction on the inner surface of the hood portion 36. As shown in FIG. 7, a recess 48 is formed in the left-right middle portion of the upper edge of the plate body 47. The bottom surface of the recess 48 is arranged at a position one step lower than both left and right ends of the upper edge of the plate body 47. When the plate body 47 is inserted into the inside of the hood portion 36, each guide rib 46 is arranged in the recess 48 (see FIG. 9).

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

[0039] As shown in Fig. 7, the plate body 47 has a plurality of insertion holes 51, 52 penetrating in the plate thickness direction (front-rear direction). The insertion holes include circular first insertion holes 51 arranged in pairs in the width direction at the left-right intermediate portion of the plate body 47, and rectangular second insertion holes 52 arranged in a large number in the width direction and height direction at both left and right ends of the plate body 47. As shown in Fig. 5, the tip end of each first terminal 16 is inserted into each first insertion hole 51 in a positioned state (Fig. 5 shows only one first terminal 16). The tip end of each general male terminal is inserted into each second insertion hole 52 in a positioned state.

[0040] 5 and 7, the moving plate 17 has a pair of left and right protective parts 53 that protrude forward from the opening edge of each first insertion hole 51 on the front surface of the plate body 47. Each protective part 53 has a plate shape with an arcuate cross section that extends along both the left and right sides of the lower part of the opening edge of each first insertion hole 51, and is disposed so as to cover the tip of each first terminal 16 from both the left and right sides.

[0041] As shown in FIG. 7, the moving plate 17 has a pair of left and right protruding parts 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 protruding part 54 is disposed on the moving plate 17 at a position above each protective part 53 and on the left and right inner side (the left and right center side of the moving plate 17) of each through hole 49. Each protruding part 54 is formed in a plate shape with a plate surface facing in the up and down direction. As shown in FIG. 7 and FIG. 8, each protruding part 54 has a protruding body 55 whose outer edge is rectangular in a plan view. The protruding body 55 has a deflection allowing part 56 at the left and right intermediate part, which penetrates in the plate thickness direction (up and down direction) and extends in the front and rear direction. The rear end of the deflection allowing part 56 opens on the rear surface of the plate body 47. The front part of the protruding body 55 is a solid pressing part 57 having a constant vertical thickness as a whole. The front end of the deflection allowing part 56 is closed by the pressing part 57. The front end surface of the pressing portion 57 constitutes the tip surface of the protruding portion 54 in the protruding direction, and is disposed forward of each of the protective portions 53. The front end surface of the pressing portion 57 constitutes an interference surface 58 along the left-right direction. As will be described later, the interference surface 58 of the pressing portion 57 is capable of interfering with the second lance 21 that has been deflected and deformed into the deflection space 25 (see FIG. 10).

[0042] As shown in Figures 7 and 8, each protrusion 54 has an interlocking portion 59 that interlocks left and right from the inner left and right end faces of the protrusion body 55 (opposing faces of the protrusion bodies 55 of each protrusion 54 facing each other). The interlocking portion 59 is disposed in the front-to-rear middle portion of the protrusion 54 at a position overlapping with the deflection allowing portion 56 in the left-to-right direction. As shown in Figures 1 and 8, the front surface of each interlocking portion 59 is inclined toward the rear. The rear surface of each interlocking portion 59 is disposed along the left-to-right direction. The end surface of each interlocking portion 59 is disposed to extend in the front-to-rear direction between the front and rear surfaces.

[0043] <Function of Connector 10> The moving plate 17 is assembled to the hood portion 36 so as to be movable in the front-rear direction between an initial position and a mating position. At the mating position, as shown in Fig. 1, the moving plate 17 is located at the rear side of the hood portion 36, and the plate body 47 is disposed in contact with or close to the front surface of the terminal accommodating portion 35. At the initial position, as shown in Fig. 9, the moving plate 17 is located away from the rear side of the hood portion 36 toward the opening side, and the plate body 47 is disposed away from the terminal accommodating portion 35.

[0044] As shown in FIG. 9, in the initial position, the holding body 42 of the holding part 41 is inserted into the through hole 49 of the plate body 47. Here, the forward movement restricting part 43 is arranged to be in contact with the front surface of the plate body 47. This restricts the moving plate 17 from moving toward the opening side (front side) of the hood part 36. Also, in the initial position, the retreat restricting part 44 is arranged to be in contact with the rear surface of the plate body 47. This restricts the moving plate 17 from moving toward the back side (rear side) of the hood part 36. As shown in FIG. 5, the tip part of the first terminal 16 passes through the first insertion hole 51 of the plate body 47, and the tip face is exposed on the front side of the plate body 47.

[0045] When the second connector 11 and the first connector 12 start to be mated, the protrusions 54 are fitted into the respective deflection spaces 25 of the second housing 13, and the locked portions 59 of the protrusions 54 interfere with the respective locking portions 26. As a result, the protrusion main bodies 55 of the protrusions 54 are deflected and deformed in the width direction narrowing the deflection allowance portions 56. As the mating of the second connector 11 and the first connector 12 progresses and the locking portions 26 climb over the respective locked portions 59, the protrusion main bodies 55 elastically return to their original state, and the locking portions 26 are disposed opposite and contactable with the rear surfaces of the respective locked portions 59 (the rear surfaces as viewed from the first connector 12) (see FIG. 1).

[0046] While each protruding body 55 is deformed, the tip of each holding portion 41 enters each through hole 31 of the second housing 13, and the release portion 32 interferes with the advancement restriction portion 43. As a result, the holding body 42 of each holding portion 41 is deformed deformed outwardly to the left and right in the through hole 49 with the front surface of the terminal accommodating portion 35 as a fulcrum, and the engagement of the retreat restriction portion 44 with respect to the plate body 47 is released. Then, the front surface of the second housing 13 (the front surface as 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 as viewed from the first connector 12). At the same time as or slightly before the second housing 13 abuts against the plate body 47, each protruding body 55 elastically returns to its original state. By further fitting, the moving plate 17 is pressed against the second housing 13 and retreats toward the fitting position. In the process of the moving plate 17 moving backward, the holding body 42 of each holding portion 41 elastically returns to its original position.

[0047] 1, when the moving plate 17 reaches the mating position, the plate body 47 is disposed so as to be sandwiched between the front surface of the terminal accommodating 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 lock arm 29 locks the lock portion 45, and the second connector 11 and the first connector 12 are held in a mated state. Also, at the mating position, the tip portions of the second terminal 14 and the first terminal 16 fit together and are connected to each other.

[0048] 2, when the pressing portion 57 of the protrusion 54 enters the deflection space 25, it faces and can come into contact with the upper surface of the tip portion (the portion forward of the locking projection 24) of the lance body 23 of the second lance 21, and suppresses the displacement of the second lance 21 into the deflection space 25. This maintains the state in which the locking projection 24 of the second lance 21 fits into the locking recess 34 and locks the second terminal 14.

[0049] In contrast, if the second terminal 14 is not inserted to the normal depth into the first female accommodating chamber 18 and remains in the half-inserted position, the locking projection 24 rides up on the outer peripheral surface of the second terminal 14, and the lance body 23 of the second lance 21 is disposed protruding obliquely upward into the deflection space 25, as shown in Fig. 10. When the second connector 11 and the first connector 12 start to be mated with the second terminal 14 remaining in the half-inserted position, the interference surface 58 of the projection 54 abuts against the tip surface of the lance body 23, and further mating of the second connector 11 and the first connector 12 is stopped. This makes it possible to avoid a situation in which the second connector 11 and the first connector 12 are mated with the second terminal 14 remaining in the half-inserted position in the first female accommodating chamber 18.

[0050] Furthermore, if the second connector 11 is to be mated with the first connector 12 in an incorrect position tilted from the correct mating position, the front surface of the second housing 13 (the front surface as seen from the second connector 11) will interfere with the interference surface 58 of the protrusion 54. The interference of the second housing 13 with the interference surface 58 of the protrusion 54 stops further mating of the second housing 13 in the incorrect position. As a result, it is possible to prevent the second connector 11 and the first connector 12 from being mated in a twisted manner.

[0051] When the second connector 11 and the first connector 12, which are in a mated state, are to be separated for reasons such as maintenance, the lock arm 29 is disengaged from the lock portion 45, and the second housing 13 is moved in a separation direction in which the second housing 13 escapes from the inside of the hood portion 36. As the second housing 13 moves in the separation direction from the state shown in Fig. 1, each of the locking portions 26 hooks and presses each of the locked portions 59 from the rear (rear when viewed from the first connector 12), and the moving plate 17 is also moved in the separation direction together with the second housing 13.

[0052] In the process of the moving plate 17 moving toward the initial position, each of the retreat restricting portions 44 slides on the inner surface of each of the through holes 31, and the holding body 42 of each of the holding portions 41 is bent outward to the left and right. When the moving plate 17 reaches the initial position, the holding body 42 of each of the holding portions 41 elastically returns, and the plate body 47 is again sandwiched between the advance restricting portion 43 and the retreat restricting portion 44. As a result, the moving plate 17 is held at the initial position and is placed in a state where its movement is restricted. Furthermore, when the second housing 13 is moved in the removal direction, the plate body 47 is locked to the advance restricting portion 43, while the protruding body 55 of each protruding portion 54 is bent and the locking portions 26 are released from the locked portions 59. As a result, the second housing 13 is removed from the hood portion 36, leaving the moving plate in the initial position.

[0053] As described above, the moving plate 17 of the first embodiment is arranged to be movable between a mating position located at the rear side relative to the hood portion 36 and an initial position located away from the rear side toward the opening side. The tip of the first terminal 16 is protected by the moving plate 17 in the initial position, and is connected to the second terminal 14 in the mating position. The second housing 13 has a second lance 21 that is flexible and prevents the second terminal 14 from coming off, a bending space 25 that allows the bending operation of the second lance 21, and a locking portion 26 arranged in the bending space 25. Furthermore, the moving plate 17 has a plate body 47 through which the first terminal 16 penetrates, and a protruding portion 54 that protrudes from the plate body 47. The protruding portion 54 has a locked portion 59 that is arranged in the bending space 25 at the mating position and is locked by the locking portion 26 in the removal direction from the mating position to the initial position.

[0054] The above-mentioned moving plate 17 has a function (protection function) of protecting the tip of the first terminal 16 at the initial position. In addition, the protruding portion 54 of the moving plate 17 has a function (return function) of pulling the moving plate 17 back from the mating position to the initial position, and a function (retainer function) of restricting the bending of the second lance 21 by being disposed in the bending space 25. Therefore, the structure of the moving plate 17 can be simplified compared to when each function (protection function, return function, retainer function) is provided in a separate portion of the moving plate 17, and the locking mechanism of the moving plate 17 can be made smaller. In particular, since the protruding portion 54 is disposed in the bending space 25 of the second lance 21, the second housing 13 does not become large. As a result, the connector 10 of the present embodiment 1 can provide the return structure of the moving plate 17 without taking up a large space.

[0055] Further, the protruding portion 54 has a plate-shaped protruding body 55 with its width oriented in a direction (left-right direction) intersecting the bending direction of the second lance 21. The protruding body 55 is formed so as to be capable of bending and deforming in the plate width direction due to interference between the locked portion 59 and the locking portion 26. Because the protruding portion 54 bends and deforms in the plate width direction, which is a direction intersecting the bending direction of the second lance 21, it is possible to provide a structure that is less susceptible to bending and deforming in the bending direction of the second lance 21, and it is possible to satisfactorily perform the function of suppressing the bending action of the second lance 21.

[0056] Furthermore, the protruding body 55 has a deflection-permitting portion 56 in the left-right intermediate portion, and the locked portions 59 are shaped to project from the left and right end faces of the protruding body 55. This allows the protruding portion 54 to bend and deform in the plate width direction while maintaining the plate width in the left-right direction, thereby ensuring the strength required to suppress the deflection of the second lance 21.

[0057] Furthermore, the protruding body 55 has a solid pressing portion 57 that covers the second lance 21 at the mating position, located closer to the tip end than the deflection allowing portion 56. Since the solid pressing portion 57 can come into contact with the second lance 21, the function of suppressing the deflection of the second lance 21 can be performed with high reliability.

[0058] Furthermore, the tip surface of the protrusion 54 forms an interference surface 58 that can interfere with the second lance 21 that has been flexed and deformed into the flex space 25. When the second terminal 14 remains in the half-inserted position in the second housing 13 and the second lance 21 is pressed by the second terminal 14 and flexes and deforms into the flex space 25, the interference surface 58 of the protrusion 54 interferes with the second lance 21 that has been flexed and deformed into the flex space 25, and further fitting of the second housing 13 is stopped. This makes it possible to prevent the second housing 13 from being fitted into the inside of the hood portion 36 with the second terminal 14 remaining in the half-inserted position in the second housing 13.

[0059] [Another embodiment of the present disclosure] The above-described first embodiment disclosed herein should be considered as illustrative in all respects and not restrictive. In the case of the above-mentioned embodiment 1, the deflection allowing portion 56 has a shape penetrating in the plate thickness direction through the left and right intermediate portion of the protruding body 55. In contrast to this, according to other embodiments, the deflection allowing portion may have a shape in which the left and right intermediate portion of the protruding body is made thinner than both left and right end portions to allow deflection deformation. In the first embodiment, the first terminal 16 is a coaxial terminal having a shielding layer, whereas in other embodiments, the first terminal may be a general male terminal having no shielding layer. In the case of the above-mentioned embodiment 1, the terminals of the first connector 12 are composed of the first terminal 16 as a coaxial terminal and a general male terminal, and the terminals of the second connector 11 are composed of the second terminal 14 as a coaxial terminal and a general female terminal. In contrast, according to another embodiment, 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 case of the above-mentioned embodiment 1, two protrusions 54 are provided on the moving plate 17, and each of the protrusions 54 is provided with one locked portion 59. In contrast, according to other embodiments, one or more protrusions may be provided on the moving plate, and each of the protrusions may be provided with multiple locked portions.
