Description

Technical Field

[0001] The present invention relates to a rod type connector. Background Art

[0002] As a connector with a detection component, the connector described in Japanese Patent Gazette No. 2009-43464 (hereinafter referred to as Patent Document 1) is known in the past. The connector is provided with a pair of male and female shells that can be interlocked with each other, and a detection component that can be movably installed on the female shell between a standby position and a detection position. In the standby position, the temporary stop portion of the detection component is locked with the abutment edge of the female shell, limiting the movement of the detection component to the detection position. When the two shells are properly engaged, the abutment portion of the male shell interferes with the temporary stop portion, releasing the stop state of the temporary stop portion and the abutment edge. As a result, the detection component can move to the detection position and can detect that the two shells are in a properly engaged state. Prior art literature Patent Literature

[0008] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples.

[0009] (1) The lever-type connector of the present invention can be mated with a connector on the other side, and the lever-type connector comprises: a housing; a lever that can be rotatably assembled on the housing between a mating start position and a mating completion position; and a detection member that can be movably mounted on the housing between a standby position and a detection position, allowing the detection member to move from the standby position to the detection position when the lever is located at the mating completion position, wherein the housing comprises a first stopper and a locking arm, wherein the first stopper, when the lever is located at the mating start position, stops at the detection member to restrict the detection member from moving from the standby position to the detection position; the locking arm , the rod is locked on the rod when the rod is in the mating completion position, the locking arm has a second locking portion, the second locking portion is locked on the detection member to limit the movement of the detection member from the standby position to the detection position, the second locking portion is configured to be able to be locked to the detection member by making the locking arm and the rod slide and bend and deform during the process of the rod rotating from the mating start position toward the mating completion position; the first locking portion is configured to be able to be locked to the detection member during the process of the rod rotating from the mating start position toward the mating completion position until the second locking portion can be locked to the detection member.

[0010] According to such a structure, since the locking arm is provided with the second stopper, the second stopper is configured to be able to be stopped with the detection member by bending and deforming the locking arm, so even if the detection member is forcibly pressed in when the lever-type connector and the other-side connector are in a state close to being properly engaged, the detection member can be restricted from moving from the standby position to the detection position by the second stopper. On the other hand, when the lever-type connector and the other-side connector are properly engaged, the locking arm is elastically reset, the second stopper leaves the detection member, and the detection member can move to the detection position. In this way, by providing the second stopper that can be stopped with the detection member in conjunction with the bending and deformation of the locking arm, the reliability of the mating detection of the lever-type connector can be improved.

[0011] (2) Preferably, the detection component comprises a main body, an arm and a locking protrusion, the arm extending from the main body can bend and deform; the locking protrusion is arranged at the top end of the arm, the main body can be locked with the second locking portion, when the rod is located at the mating start position, the locking protrusion is locked with the first locking portion, and during the process of the rod rotating from the mating start position toward the mating completion position, the locking protrusion interferes with the other side connector, the arm is bent and deformed, thereby releasing the locking of the locking protrusion and the first locking portion.

[0012] According to such structure, by engaging the lever type connector with the other side connector, the first locking portion and the locking projection can be released. In addition, even if the first locking portion and the locking projection are released, the second locking portion and the main body can be locked.

[0013] (3) Preferably, the above-mentioned rod-type connector also has a detection terminal, which is held by the shell and forms a detection circuit by contacting a detection terminal on the other side provided on the other side connector. The locking arm is arranged opposite to the detection terminal, and the rod has a pressing portion, which presses the locking arm toward the detection terminal to separate the detection terminal from the other side detection terminal. When the rod reaches the mating completion position, the pressing portion releases the pressing of the locking arm, and the detection terminal contacts the detection terminal on the other side.

[0014] According to such a structure, when the lever-type connector and the other connector are properly mated, the lock arm is elastically reset, and the detection terminal and the other detection terminal contact to form a detection circuit. Therefore, in addition to the detection member, the detection circuit can also be used for mating detection.

[0015] [Details of Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described. 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 equivalent to the claims.

[0016] <Implementation Method> Reference Figures 1 to 20 The embodiment of the present invention is described. In the following description, the direction indicated by the arrow line Z is regarded as the upward direction, the direction indicated by the arrow line X is regarded as the front direction, and the direction indicated by the arrow line Y is regarded as the left direction. In addition, with respect to a plurality of identical components, sometimes only some of the components are marked with reference numerals, and the reference numerals of the other components are omitted. Figure 1 As shown, the mating connector 60 that the lever-type connector 10 can be mated with is a substrate connector mounted on a circuit substrate (not shown). In this embodiment, three lever-type connectors 10 can be mated with one mating connector 60. In the figure, only the lever-type connector 10 that is mated with the central portion of the mating connector 60 is shown.

[0017] [Mate side connector] The counterpart connector 60 includes a counterpart housing 61, a plurality of counterpart terminals 62 and a plurality of counterpart detection terminals 63 held in the counterpart housing 61. The counterpart housing 61 is made of synthetic resin and has a horizontally long rectangular shape as a whole. Figure 1 and Figure 2As shown, the mating housing 61 has a plurality of fitting recesses 64 in which the lever-type connector 10 can be fitted. A pair of cam pins 65 are provided on both side walls 64A on the left and right sides of the fitting recess 64. One cam pin 65 is provided on each side wall 64A and is arranged symmetrically. The cam pin 65 is formed in a cylindrical shape.

[0018] like Figure 6 As shown, the other-side terminal 62 and the other-side detection terminal 63 are composed of metal needle-shaped terminals, and are held on the bottom wall 64B in a manner that penetrates the bottom wall 64B that constitutes the mating recess 64 in the front-to-back direction. One end of the other-side terminal 62 and the other-side detection terminal 63 protrudes from the bottom wall 64B toward the mating recess 64 and extends in the front-to-back direction. The other ends of the other-side terminal 62 and the other-side detection terminal 63 are arranged outside the mating recess 64 and are bent downward. As the other-side connector 60 and the rod-type connector 10 are properly mated, the other-side detection terminal 63 is electrically connected to the detection terminal 30 provided on the rod-type connector 10 (refer to Fig.17 ).

[0019] Figure 8 This is a cross-sectional view, so only one detection terminal 63 on the other side is shown, but Figure 1 and Figure 2 As shown, one mating recess 64 of the mating housing 61 holds two mating detection terminals 63 at intervals in the width direction. The two mating detection terminals 63 are connected to the detection circuit of the device. The two mating detection terminals 63 cannot be connected (the detection circuit is disconnected) before contacting the detection terminals 30 of the lever-type connector 10. When the detection terminals 30 and the two mating detection terminals 63 are in contact with each other, the detection circuit is formed.

[0020] like Figure 3 and Figure 5 As shown, the other side housing 61 is provided with a window portion 66 that passes through the upper wall 64C of the fitting recess 64 in the vertical direction. As described later, the window portion 66 receives the locking protrusion 52A (see Fig.18 ).like Figure 5 As shown, the other side housing 61 has a release protrusion 67 protruding downward from the lower surface of the upper wall 64C at the rear end of the upper wall 64C. As described later, the release protrusion 67 is a member for releasing the locking of the first locking portion 27 and the locking protrusion 52A (see Fig.15 ).

[0021] [Lever type connector] like Figure 1 As shown, the lever-type connector 10 includes a housing 20, a plurality of terminals (not shown), a detection terminal 30 (see Figure 8), rod 40 and detection member 50. The terminal is a female terminal and is connected to the other side terminal 62. The rod 40 can Figure 6 The chimera start position shown is Figure 7 When the lever 40 is rotated from the mating start position to the mating completion position, the lever-type connector 10 is mated toward the mating connector 60, and vice versa, when it is rotated from the mating completion position to the mating start position, the lever-type connector 10 is disengaged from the mating connector 60.

[0022] [case] The housing 20 is made of synthetic resin, such as Figure 2 As shown in FIG. 1 , the housing 20 is formed into a substantially square block. A terminal receiving portion 21 is provided through the housing 20 in the front-to-back direction, and the terminal receiving portion 21 receives the terminal. Figure 8 As shown, a detection terminal receiving portion 22 is provided through the housing 20 in the front-rear direction, and the detection terminal receiving portion 22 receives the detection terminal 30. The detection terminal receiving portion 22 is arranged on the upper side of the housing 20 and in the center in the left-right direction.

[0023] [Locking Arm] like Fig.10 As shown in FIG. 1 , the housing 20 includes a locking arm 23 extending rearward from the upper wall of the housing 20. The locking arm 23 is configured to be able to bend and deform in the vertical direction with the front end connected to the upper wall of the housing 20 as the base end. The locking arm 23 includes a locking arm body 23A and a fitting locking portion 23B protruding upward from the rear of the locking arm body 23A. Figure 3 and Figure 4 As shown, in the lock arm 23 of this embodiment, two engaging lock portions 23B are provided at intervals in the left-right direction. When the lever-type connector 10 and the mating connector 60 are properly engaged, the engaging lock portion 23B is locked with the locking portion 45B provided on the lever 40 (see Fig.16 ).

[0024] like Fig.10 As shown, the upper surface of the engaging locking portion 23B is a sliding portion 24, and the upper part of the sliding portion 24 is a convex curved surface. A pressing start portion 25 is provided on the upper side of the rear end portion of the locking arm 23, and the pressing start portion 25 is in a rounded shape.

[0025] [Second locking part] The rear end surface of the lock arm 23 is a second locking portion 23D. As described later, the second locking portion 23D is configured to be locked with the detection member 50 when the lock arm 23 is bent and deformed (see Fig.12 and Fig.14 ).

[0026] like Figure 5As shown, the housing 20 has a storage space SP that can store the detection member 50. The storage space SP includes a first storage space SP1 and a pair of second storage spaces SP2. The first storage space SP1 is provided at the lower side of the portion close to the rear end of the locking arm 23. The second storage space SP2 is connected to the first storage space SP1 and is provided on both sides of the first storage space SP1.

[0027] [First locking portion] like Figure 5 and Fig. 9 As shown in FIG. 1 , the housing 20 includes a first stopper 27, and the first stopper 27 is disposed at a position close to the front end of the second storage space SP2. The first stopper 27 extends in the width direction (left-right direction) and is connected to the inner wall constituting the second storage space SP2. The housing 20 includes an opening 27A behind the first stopper 27. The opening 27A opens in the up-down direction, so that the second storage space SP2 is connected to the external space (see FIG. 1 ). Fig.13 ).

[0028] like Figure 5 As shown, the housing 20 includes an engaging recess 28 disposed on the side of the second storage space SP2. Specifically, the housing 20 includes an engaging recess 28 disposed on the right side of the second storage space SP2 on the right side and an engaging recess 28 disposed on the left side of the second storage space SP2 on the left side. The engaging recess 28 is formed into a groove-like structure, and is recessed to the side from the inner wall of the side of the second storage space SP2.

[0029] like Figure 5 and Fig. 9 As shown in FIG. 1 , the housing 20 includes a temporary stop arm 29, which defines the rear half of the second storage space SP2 from above. The temporary stop arm 29 is elongated in the front-to-back direction and is configured to be able to bend and deform in the vertical direction with the front end connected to the upper wall of the housing 20 as the base end. Fig. 9 As shown, a temporary stop protrusion 29A protruding downward from the lower surface of the temporary stop arm 29 is provided at the rear end of the temporary stop arm 29. The rear end of the temporary stop protrusion 29A is inclined in a manner that it is located downward as it moves toward the front. The front end surface of the temporary stop protrusion 29A is a steep surface that is substantially orthogonal to the axis extending in the front-rear direction.

[0030] like Figure 8 As shown in FIG. 2 , the locking arm 23 is arranged so as to partition the upper portion of the detection terminal storage portion 22. Fig.12 As shown, the lock arm 23 is provided with a protrusion 23C protruding from the lock arm body 23A toward the inner side of the detection terminal accommodating portion 22. The protrusion 23C presses the detection terminal 30 when the lock arm 23 is bent and deformed downward.

[0031] [Detection terminal] like Figure 8 As shown, the detection terminal 30 comprises: a substrate portion 31, which is formed by bending a conductive metal plate into a predetermined shape, etc., and is arranged along the inner surface of the lower side of the detection terminal storage portion 22; and a spring portion 32, which is folded back from the rear end of the substrate portion 31 toward the front and bent into a predetermined shape. The spring portion 32 has a contact portion 33 arranged at the front end portion of the spring portion 32 and a snap-fit ​​portion 34 arranged at the rear portion of the spring portion 32. The contact portion 33 and the snap-fit ​​portion 34 are bent in a manner of protruding upward in a mountain shape. The spring portion 32 is divided into two branches on the top end side (front end side) and is provided with a pair of left and right contact portions 33.

[0032] like Fig.17 As shown, when the lever-type connector 10 and the mating connector 60 are properly mated, each contact portion 33 contacts the mating detection terminal 63. Thus, the two mating detection terminals 63 are electrically connected to the detection terminal 30, forming a detection circuit.

[0033] like Fig.12 As shown, the engagement portion 34 is pressed by the protrusion 23C of the lock arm 23. As the engagement portion 34 is pressed by the protrusion 23C, the contact portion 33 is displaced so as to approach the substrate portion 31.

[0034] like Figure 6 and Figure 7 As shown, a pair of rotation shafts 26 are provided on both side surfaces of the housing 20 to protrude outward in the left-right direction. The pair of rotation shafts 26 are provided one on each side surface and are arranged in a left-right symmetrical manner.

[0035] [Pole] The lever 40 is rotatably supported by the housing 20, and is operated when the lever-type connector 10 is mated with the mating connector 60 and when the mating is released, thereby functioning as a force-increasing mechanism. Figure 6 The starting position of the chimera is shown to Figure 7 That is, when the lever 40 is rotated counterclockwise from the mating start position to the mating completion position, the lever-type connector 10 is properly mated to the mating connector 60 .

[0036] The rod 40 is made of synthetic resin. Figure 3 and Figure 4 As shown, the lever 40 includes a pair of cam plates 41 and an operating portion 42 that connects the distal ends of the pair of cam plates 41 to each other, and is gate-shaped as a whole.

[0037] like Figure 6 and Figure 7As shown, each cam plate 41 is formed with a shaft hole 41A penetrating the cam plate 41. The rotation shaft 26 is inserted into the shaft hole 41A. The lever 40 is supported by the housing 20 so as to be rotatable about the rotation shaft 26.

[0038] The cam plate 41 has a track 43, and the cam pin 65 enters the track 43. The track 43 has an inlet 43A opened forward at the outer edge of the cam plate 41, and is formed so as to approach the shaft hole 41A as it moves from the inlet 43A toward the terminal 43B. When the lever 40 is at the mating start position, the lever-type connector 10 and the mating connector 60 are shallowly mated. Figure 6 As shown, the cam pin 65 enters the inlet 43A of the track 43 .

[0039] When the lever 40 is moved from the mating start position to the mating completion position, the cam pin 65 engages with the inner wall of the rail 43, thereby mating the lever-type connector 10 and the mating connector 60. Figure 7 As shown, the cam pin 65 is located at the terminal end 43B of the rail 43. On the contrary, when the lever 40 is moved from the mating completion position to the mating start position, the cam pin 65 engages with the inner wall of the rail 43, thereby separating the lever-type connector 10 and the mating connector 60.

[0040] [First pressing portion, second pressing portion] like Fig.10 As shown, the lever 40 includes a second pressing portion 45 (an example of a pressing portion) protruding from the operating portion 42 toward the inner side of the rotational radial direction, and a first pressing portion 44 (an example of a pressing portion) protruding from the second pressing portion 45 toward the inner side of the rotational radial direction. Here, the rotational radial direction refers to the extension direction of an axis that is orthogonal to the extension direction (left-right direction) of the rotational axis 26 and passes through the rotational center, with the direction closer to the rotational axis 26 being the inner side and the direction away from the rotational axis 26 being the outer side. Figure 4 As shown, the second pressing portion 45 is disposed at the left-right center of the operation portion 42. The first pressing portion 44 is smaller than the second pressing portion 45 in the left-right direction and is disposed at the left-right center of the second pressing portion 45.

[0041] like Fig.14 As shown in FIG. 1 , the second pressing portion 45 includes a sliding portion 45A having a curved surface. The sliding portion 45A has an arc shape that is a portion of a circle centered on the rotation shaft 26 when viewed from the side. Fig.16 As shown in the figure, the rear end surface of the second pressing portion 45 is the locking portion 45B, with the lever 40 being located at the mating completion position as a reference. When the lever-type connector 10 and the mating connector 60 are properly mated, the locking portion 45B is arranged opposite to the mating lock portion 23B, and the locking portion 45B and the mating lock portion 23B are locked, thereby restricting the lever 40 from rotating in the direction of releasing the mating.

[0042] The first pressing portion 44 protrudes from the sliding portion 45A in a mountain shape. The first pressing portion 44 is provided at the front side portion of the sliding portion 45A, with the lever 40 being located at the mating completion position as a reference.

[0043] [Detection component] The detection member 50 is made of synthetic resin. Fig. 20 As shown, the detection member 50 includes a main body 51, an arm 52 extending from the main body 51, and a locking protrusion 52A arranged at the top end of the arm 52. The main body 51 is roughly door-shaped with both ends in the width direction (left-right direction) extending forward. The arm 52 extends forward from the right end and the left end of the main body 51, respectively. The arm 52 can bend and deform in the up and down directions with the rear end connected to the main body 51 as the base end. The locking protrusion 52A is arranged at a position close to the front end of the arm 52 and protrudes upward from the arm 52. An inclined portion 52B is formed on the upper part of the front side portion of the locking protrusion 52A. The inclined portion 52B is arranged in a manner of descending and tilting as it moves forward (refer to Fig.15 ).like Fig. 9 As shown in FIGS. 1 and 14 , the locking protrusion 52A can be locked with the first locking portion 27 .

[0044] like Fig. 20 As shown in FIG. 1 , a first recess 53 that is recessed from the main body 51 and a second recess 54 that is further recessed from the bottom surface of the first recess 53 are formed in the left and right central portions of the main body 51. The second recess 54 is disposed in the left and right central portions of the first recess 53. When the lever 40 rotates, the first pressing portion 44 enters the interior of the second recess 54, and the second pressing portion 45 enters the interior of the first recess 53 (see FIG. 1 ). Figure 4 and Fig.12 ).

[0045] An operating rib 55 is provided at the rear end of the main body 51 and extends upward from the upper surface of the main body 51. By pressing the operating rib 55 or the rear surface of the main body 51 with a finger to operate the detection member 50, the detection member 50 can be moved to the standby position (see Fig. 9 ) and detection position (refer to Fig.18 In the present embodiment, the detection position is arranged forward of the standby position, and the detection member 50 can move in the front-rear direction.

[0046] like Figure 5 As shown, the detection member 50 includes two protrusions 56 protruding to the left and right from both sides of the main body 51. The protrusions 56 are received in the engagement recess 28. The protrusions 56 slide against the inner wall of the engagement recess 28 to guide the movement of the detection member 50.

[0047] like Fig. 20As shown in FIG. 1 , the detection member 50 includes a temporary stopper 57 protruding from the upper surface of the main body 51. The temporary stopper 57 is provided on the right and left sides of the upper surface of the main body 51. Fig. 9 As shown in the figure, the front side portion of the temporary stop portion 57 is inclined in a manner that it is located upward as it moves toward the rear. The rear end surface of the temporary stop portion 57 is a steep surface that is substantially orthogonal to the axis extending in the front-to-back direction. The temporary stop portion 57 is configured to be able to be locked with the temporary stop protrusion 29A when the detection member 50 is located in the standby position. The temporary stop portion 57 and the temporary stop protrusion 29A are locked, thereby preventing the detection member 50 from moving backward from the standby position.

[0048] [Assembly of the detection member to the housing] The assembly of the detection member 50 to the housing 20 is described. First, the arm portion 52 of the detection member 50 and the side portion of the main body 51 are inserted into the first storage space SP1. After the arm portion 52 is arranged in the first storage space SP1, the front end of the temporary stop portion 57 and the rear end of the temporary stop protrusion 29A slide, and the temporary stop arm portion 29 is bent and deformed upward. When the detection member 50 is further pressed forward, the temporary stop protrusion 29A passes over the temporary stop portion 57. The temporary stop arm portion 29 returns to a natural state, and the detection member 50 is arranged in the standby position. When the detection member 50 is in the standby position, it is stopped by the stop protrusion 52A and the first stop portion 27, thereby limiting the movement of the detection member 50 forward. In addition, the rear end face of the temporary stop portion 57 and the front end face of the temporary stop protrusion 29A are stopped, thereby limiting the movement of the detection member 50 backward.

[0049] [Detection of the mating of the detection member to the lever-type connector] Next, corresponding to the progress of the mating between the lever-type connector 10 and the mating connector 60 , the locking of the detection member 50 and the housing 20 and the mating detection by the detection member 50 will be described.

[0050] The lever-type connector 10 in which the detection member 50 is assembled in the standby position is positioned relative to the mating connector 60, and the housing 20 is inserted into the fitting recess 64 (see Figure 1 and Figure 6 ). In the stage before the shallow insertion operation begins, such as Fig.10 As shown, the lever 40 is separated from the lock arm 23, so the lock arm 23 is in a natural state. Therefore, the second locking portion 23D of the lock arm 23 is not arranged to face the main body 51 of the detection member 50 in the front-rear direction.

[0051] When the cam pin 65 enters the entrance 43A of the rail 43, the operation portion 42 is operated, and the lever 40 rotates from the fitting start position toward the fitting completion position. Fig.12As shown, first, the first pressing portion 44 of the rod 40 contacts the pressing start portion 25 of the lock arm 23. As a result, the lock arm 23 is bent and deformed downward and enters the first storage space SP1. As a result, the second stopper 23D and the main body 51 are opposed to each other in the front-to-back direction. In the state where the lock arm 23 is bent and deformed in this way, the second stopper 23D and the main body 51 are locked, thereby restricting the detection member 50 from moving forward toward the detection position.

[0052] In addition, when the rod 40 is moved from the mating start position (see Fig. 9 )arrive Fig.11 The position shown (with Fig.12 The first locking portion 27 and the locking projection 52A are opposed to each other in the front-rear direction until the first locking portion 27 and the locking projection 52A are locked, so that the detection member 50 can be restricted from moving to the detection position.

[0053] When the rod 40 is further rotated and approaches the mating completion position, as shown in FIG. Fig.13 As shown in FIG. 1 , the release protrusion 67 provided on the upper wall 64C of the mating housing 61 contacts the locking protrusion 52A via the opening 27A of the housing 20. As a result, the arm portion 52 is bent and deformed downward, and the locking of the locking protrusion 52A and the first locking portion 27 is released. Here, unlike the present embodiment, in the case where the second locking portion 23D is not provided, the detection member 50 is allowed to move to the detection position. That is, even in a state where the lever-type connector 10 and the mating connector 60 are not properly mated, it is possible that they are erroneously detected as being properly mated.

[0054] However, in this embodiment, when the rod 40 is located Fig.13 In the state of the position shown, Fig.14 As shown in FIG. 1 , the lock arm 23 is pressed by the second pressing portion 45 after the first pressing portion 44 and is bent and deformed. Specifically, the sliding portion 45A of the second pressing portion 45 slides with the sliding portion 24. Therefore, the second locking portion 23D and the main body 51 can be locked, and the detection member 50 cannot be moved to the detection position. Therefore, in Fig.13 and Fig.14 At the rotation angle shown, the detection member 50 does not move to the detection position, so it will not be erroneously detected as a normal fit.

[0055] When the rod 40 is further rotated to reach the engagement completion position, as shown in FIG. Fig.16As shown, the sliding contact between the sliding portion 45A of the second pressing portion 45 and the slidably contacted portion 24 is released, and the locking arm 23 returns to a natural state. As a result, the locking portion 45B of the second pressing portion 45 and the interlocking locking portion 23B of the locking arm 23 are configured to be interlocked. By interlocking the locking portion 45B and the interlocking locking portion 23B, the rod 40 can be restrained from rotating from the interlocking completion position to the interlocking start position. In addition, by restoring the locking arm 23 to a natural state, the second interlocking portion 23D and the main body 51 are not aligned in the front-to-back direction, and the forward movement of the detection member 50 is not restricted by the second interlocking portion 23D. Therefore, as Fig.19 As shown, the detection member 50 can be moved to the detection position, and the proper fitting of the mating connector 60 and the lever-type connector 10 can be detected.

[0056] In other words, from the time when the rod 40 starts to slide with the lock arm 23 until the rod 40 reaches the mating completion position, the lock arm 23 is in a state of bending and deformation, so the second locking portion 23D and the main body 51 can be locked, and the detection member 50 cannot be moved to the detection position. Therefore, even when the rod 40 is close to the mating completion position, the false detection of the normal mating can be avoided. That is, the reliability of the mating detection can be improved.

[0057] When the rod 40 is arranged in the mating completion position (refer to Fig.16 ) when the detection member 50 is pressed forward, the left and right central portions of the main body 51 are stored in the first storage space SP1 (refer to Fig.19 ). In the second storage space SP2, when the rod 40 is arranged in the mating completion position (refer to Fig.15 ) When the detection member 50 is pressed forward, the first stopper 27 and the inclined portion 52B of the stopper protrusion 52A slide, and the stopper protrusion 52A sinks below the first stopper 27. As the first stopper 27 passes over the stopper protrusion 52A, the arm 52 is naturally reset, and the detection member 50 reaches the detection position (refer to Fig.18 ). When the detection member 50 is located at the detection position, the locking protrusion 52A is arranged in the window portion 66 of the other side housing 61. The rear end surface of the locking protrusion 52A is locked with the front end surface of the first locking portion 27, thereby restricting the movement of the detection member 50 from the detection position to the standby position. When the detection member 50 is moved from the detection position to the standby position, a jig or the like is hooked on the front part of the operating rib 55 to move the detection member 50 backward.

[0058] [Detection of the mating of the detection terminal to the lever-type connector] Next, the mating detection by the detection terminal 30 will be described in correspondence with the mating progress of the lever-type connector 10 and the mating connector 60 .

[0059] In the stage before the insertion of shallow fitting operation, such as Figure 8 As shown, since the lever 40 is separated from the lock arm 23, the lock arm 23 and the detection terminal 30 are in a natural state. In addition, the detection terminal 30 and the counterpart detection terminal 63 are separated in the mating direction (front-rear direction).

[0060] When the lever 40 is rotated from the mating start position toward the mating completion position, as shown in FIG. Fig.12 As shown in FIG. 1 , the first pressing portion 44 contacts the pressing start portion 25, causing the locking arm 23 to bend and deform downward. Furthermore, the protrusion 23C of the locking arm 23 presses the engaging portion 34 of the detection terminal 30, causing the spring portion 32 to bend and deform downward. As a result, the contact portion 33 of the detection terminal 30 is pressed down to a position lower than the detection terminal 63 on the other side.

[0061] When the lever 40 is further rotated, the second pressing portion 45 presses the lock arm 23 following the first pressing portion 44, and the lock arm 23 is maintained in a state of being bent and deformed (see Fig.14 ). Therefore, the lever-type connector 10 and the mating connector 60 are mated with each other in a state where the contact portion 33 is arranged at a position that does not interfere with the mating detection terminal 63 .

[0062] When the rod 40 reaches the mating completion position, the locking arm 23 returns to the natural state, and the mating of the rod-type connector 10 and the mating connector 60 is completed. Fig.17 As shown, along with the elastic return of the lock arm 23, the spring portion 32 will also be elastically returned to the initial position, and the contact portion 33 will contact the other side detection terminal 63. In this way, the detection terminal 30 and the other side detection terminal 63 form a detection circuit, so through the conduction between the two, it can be recognized that the other side connector 60 and the lever-type connector 10 are properly mated.

[0063] As described above, regarding the mating detection by the detection terminal 30 , the detection terminal 30 and the mating detection terminal 63 are connected to form a detection circuit in conjunction with the release of the flexural deformation of the lock arm 23 , thereby improving the reliability of the mating detection.

[0064] [Regarding the Pressing of the Lock Arm by the First Pressing Part and the Second Pressing Part] In this embodiment, although not shown in detail, the configuration is such that, during the process of the lever 40 rotating from the mating start position toward the mating completion position, the second pressing portion 45 starts pressing the locking arm 23 while the first pressing portion 44 is pressing the locking arm 23. Thus, from the time when the first pressing portion 44 starts pressing the locking arm 23 to the time when the second pressing portion 45 stops pressing the locking arm 23, the locking arm 23 is maintained in a state of being bent and deformed.

[0065] In this embodiment, since the first pressing portion 44 and the second pressing portion 45 are provided, the lock arm 23 can be continuously pressed within a wider range of rotation angles than when only one pressing portion is provided. Therefore, the lever-type connector 10 and the mating connector 60 can be mated within a larger range of rotation angles, so that the mating stroke can be easily increased and the effective contact margin between the detection terminal 30 and the mating detection terminal 63 can be easily ensured. In addition, the effect of reducing the mating force of the lever 40 can be easily obtained.

[0066] [Effects of the Embodiments] According to the implementation mode, the following actions and effects are achieved. The lever-type connector 10 of the embodiment can be mated with the mating connector 60, and the lever-type connector 10 includes: a housing 20; a lever 40, which is rotatably mounted on the housing 20 between a mating start position and a mating completion position; and a detection member 50, which is movably mounted on the housing 20 between a standby position and a detection position, and allows the detection member 50 to move from the standby position to the detection position when the lever 40 is located at the mating completion position, and the housing 20 includes: a first stopper 27, which is stopped by the first stopper 27 when the lever 40 is located at the mating start position, thereby limiting the movement of the detection member 50 from the standby position to the detection position; and a locking arm 23, which is locked on the lever 40 when the lever 40 is located at the mating start position. 0 is stopped on the rod 40 in the state of being located at the mating completion position, the locking arm 23 has a second stopping portion 23D, and the second stopping portion 23D is stopped on the detection member 50, thereby limiting the movement of the detection member 50 from the standby position to the detection position, and the second stopping portion 23D is configured so that in the process of the rod 40 rotating from the mating start position toward the mating completion position, the locking arm 23 slides with the rod 40 and flexes and deforms, so that the second stopping portion 23D can be stopped on the detection member 50; the first stopping portion 27 is configured so that in the process of the rod 40 rotating from the mating start position toward the mating completion position, it can be stopped on the detection member 50 until the second stopping portion 23D can be stopped on the detection member 50.

[0067] According to such a structure, since the locking arm 23 has the second stopper 23D, the second stopper 23D is configured to be able to stop with the detection member 50 by the bending deformation of the locking arm 23. Therefore, even if the detection member 50 is strongly pressed in when the lever-type connector 10 and the other-side connector 60 are in a state close to being properly engaged, the second stopper 23D can limit the movement of the detection member 50 from the standby position to the detection position. On the other hand, when the lever-type connector 10 and the other-side connector 60 are properly engaged, the locking arm 23 is elastically reset, the second stopper 23D leaves the detection member 50, and the detection member 50 can move to the detection position. In this way, by providing the second stopper 23D that can stop with the detection member 50 in conjunction with the bending deformation of the locking arm 23, the reliability of the mating detection of the lever-type connector 10 can be improved.

[0068] In an embodiment, the detection component 50 includes: a main body 51; an arm 52, which extends from the main body 51 and can bend and deform; and a locking protrusion 52A, which is arranged at the top end of the arm 52. The main body 51 can be locked with the second locking portion 23D. When the rod 40 is located in the mating start position, the locking protrusion 52A is locked with the first locking portion 27. In the process of the rod 40 rotating from the mating start position toward the mating completion position, the locking protrusion 52A interferes with the other side connector 60, and the arm 52 is bent and deformed, thereby releasing the locking of the locking protrusion 52A and the first locking portion 27.

[0069] According to such a structure, the first locking portion 27 and the locking projection 52A can be released by fitting the lever-type connector 10 and the mating connector 60. In addition, even if the first locking portion 27 and the locking projection 52A are released, the second locking portion 23D and the main body 51 can be locked.

[0070] The lever-type connector 10 of the embodiment also includes a detection terminal 30, which is retained in the housing 20 and forms a detection circuit by contacting a detection terminal 63 on the other side provided on the other side connector 60. The locking arm 23 is arranged opposite to the detection terminal 30, and the lever 40 includes a pressing portion (a first pressing portion 44 and a second pressing portion 45). The pressing portion presses the locking arm 23 toward the detection terminal 30, thereby separating the detection terminal 30 from the detection terminal 63 on the other side. When the lever 40 reaches the mating completion position, the pressing portion releases the pressure on the locking arm 23, and the detection terminal 30 contacts the detection terminal 63 on the other side.

[0071] According to this structure, when the lever-type connector 10 and the mating connector 60 are properly mated, the lock arm 23 is elastically reset, and the detection terminal 30 and the mating detection terminal 63 contact to form a detection circuit. Therefore, in addition to the detection member 50, the detection circuit can also be used for mating detection.

[0072] <Other Implementation Methods> (1) In the above embodiment, the mating connector 60 includes three fitting recesses 64 , but the present invention is not limited thereto. The number of fitting recesses of the mating connector may be one, two, or four or more. (2) In the above embodiment, two first locking portions 27 and two locking protrusions 52A are provided, but the present invention is not limited thereto. The number of first locking portions and locking protrusions may be one or three or more. (3) In the above embodiment, the first pressing portion 44 and the second pressing portion 45 are exemplified as the pressing portion, but the present invention is not limited thereto and there may be only one pressing portion. (4) In the above embodiment, the lever-type connector 10 includes the detection terminal 30 and the mating connector 60 includes the mating detection terminal 63 , but the present invention is not limited thereto and the detection terminal and the mating detection terminal may not be provided.
