Additionally, in this specification, "ring shape," "cylindrical shape," "annular," "tube shape," "circular shape," and "wave shape" do not refer to shapes in the strict sense, but rather to shapes that enable the realization of, for example, the functions of the first or second connector of this disclosure.

[0049] (First Implementation)

[0050] Reference Figures 1-15 The first connector 100 and the second connector 200 of the first embodiment of this disclosure will be described. First, referring to... Figure 1 and Figure 2 The second connector 200 will be described.

[0051] Figure 1 This is a perspective view illustrating the second connector 200 according to an embodiment of the present disclosure. Figure 1 As shown, the second connector 200 has a central axis AX2. The second connector 200 extends along an axial direction AD2 along the central axis AX2. The second connector 200 is a male connector. In this embodiment, "front" of the second connector 200 means insertion into the first connector 100 ( Figure 3 The "back" of the second connector 200 indicates the side of the insertion tube TB2.

[0052] The second connector 200 has a protrusion 204. Specifically, the second connector 200 has a plug portion 201 and an insertion portion 202. The plug portion 201 and the insertion portion 202 are connected along the axial direction AD2. The plug portion 201 has a plug body 203, a protrusion 204, and a connecting body 205.

[0053] The plug body 203 has a cylindrical shape. A protrusion 204 protrudes from the outer peripheral surface of the second connector 200. Specifically, the protrusion 204 protrudes from the outer peripheral surface of the plug body 203 radially outward (RD2). The protrusion 204 extends circumferentially (CD2). The protrusion 204 has an annular shape. The protrusion 204 extends from the front end 203a of the second connector 200 along the axial direction (AD2) toward the rear end 206a relative to the central axis (AX2). That is, the diameter of the protrusion 204 increases from the front end 203a toward the rear end 206a of the second connector 200. The protrusion 204 is located on the rear end 203b side of the plug body 203 along the axial direction (AD2).

[0054] The connector 205 is connected to the rear end 203b of the plug 203. The connector 205 and the plug 203 are configured as a single component (one-piece molded article). The connector 205 has a cylindrical shape.

[0055] The insertion part 202 is inserted into the tube TB2. Specifically, the insertion part 202 has an insertion body 206, a connecting body 207, and a plurality of protrusions 212. The insertion body 206 is inserted into the tube TB2. The insertion body 206 has a cylindrical shape. The protrusions 212 protrude from the outer peripheral surface of the insertion body 206 toward the radially outward side of RD2. The protrusions 212 have an annular shape. The diameter of the protrusions 212 increases from the rear end 206a of the second connector 200 along the axial direction AD2 toward the front end 203a.

[0056] The connector 207 is connected to the rear end 206b of the insert 206 along the axial AD2. The connector 207 and the insert 206 are configured as a single component (one-piece molded article). The connector 207 has a cylindrical shape.

[0057] The connector 205 of the plug portion 201 is inserted into the connector 207 of the insertion portion 202. As a result, the plug portion 201 is connected to the insertion portion 202.

[0058] Figure 2 It is along Figure 1 A sectional view along line II-II. Figure 2 This shows the state where the second connector 200 is separated from the first connector 100. That is, it shows the state where the second connector 200 is not connected to the first connector 100. Figure 2 As shown, the plug portion 201 also includes a plug valve portion 208, an elastic member 209, a sealing member 210, a sealing member 211, and a flow path 213. Furthermore, the insertion portion 202 also includes a flow path 214. Flow paths 213 and 214 extend along the axial direction AD2. The front end of the flow path 214 along the axial direction AD2 is connected to the rear end of the flow path 213 along the axial direction AD2. That is, the flow path 213 is connected to the flow path 214.

[0059] A plug valve portion 208 is disposed in the flow path 213 on the front end 203a side of the plug body 203. The plug valve portion 208 is pushed from the rear end 203b side of the plug body 203 towards the front end 203a side by an elastic member 209. The plug valve portion 208 blocks the flow path 213 on the front end 203a side of the plug body 203. A sealing member 210 is mounted on the outer peripheral surface of the plug valve portion 208. The sealing member 210 is an elastic body with an annular shape. The sealing member 210 seals the flow path 213 on the front end 203a side of the plug body 203.

[0060] An elastic member 209 is disposed in the flow path 213. The elastic member 209 is elastic. The elastic member 209 is, for example, a compression coil spring. A sealing member 211 is mounted on the outer peripheral surface of the connector 205. The sealing member 211 is an elastic body with an annular shape. The sealing member 211 seals the area between the outer peripheral surface of the connector 205 and the inner peripheral surface of the connector 207.

[0061] Next, refer to Figures 3-6 The first connector 100 will be described. Figure 3 This is a perspective view showing the first connector 100 of this embodiment. Figure 4 This is an exploded perspective view showing the first connector 100.

[0062] like Figure 3 and Figure 4 As shown, the first connector 100 has a central axis AX1. The first connector 100 extends along an axial direction AD1 along the central axis AX1. The first connector 100 is a female connector. The first connector 100 is connected to the second connector 200 along the central axis AX1. Figure 1 (Connection). In this embodiment, "front" of the first connector 100 refers to the side where the second connector 200 is inserted. "Rear" of the first connector 100 refers to the side where the tube TB2 is inserted.

[0063] The first connector 100 has a first connector body 1, a mounting member 3, a working part 71, and an elastic member 11. Specifically, the first connector 100 has a working member 7. Furthermore, the working member 7 has a working part 71. The first connector body 1 extends along the axial direction AD1. The first connector body 1 connects to the second connector 200 along the central axis AX1. Figure 1 The first connector body 1 is connected to the second connector 200. Mounting member 3 is mounted on the outer peripheral surface of the first connector body 1. Details of mounting member 3 will be described later. The working member 7 is operated by the operator to switch the connection state between the first connector body 1 and the second connector 200 between a locked state and an unlocked state. The locked state indicates that the connection between the first connector body 1 and the second connector 200 cannot be disengaged. The unlocked state indicates that the connection between the first connector body 1 and the second connector 200 can be disengaged. The elastic member 11 supports the working member 7. As an example, a button is formed by the working member 7 (working part 71) and the elastic member 11.

[0064] Specifically, the first connector body 1 has a socket portion 5 and an insertion portion 9. The socket portion 5 and the insertion portion 9 are connected along the axial direction AD1. The second connector 200 has a plug portion 201 ( Figure 1 Insert the connector 5. In addition, the mounting member 3 is mounted on the outer peripheral surface of the connector 5.

[0065] The socket portion 5 has a socket body 50. The second connector 200 has a plug body 203 ( Figure 1 Insert the socket body 50. The socket body 50 has a cylindrical shape.

[0066] The socket body 50 has an opening 51. The opening 51 has a circular shape. The opening 51 is located on the front end 5a side of the socket body 50. The opening 51 opens along the axial direction AD1.

[0067] Next refer to Figure 3 and Figure 4The structure related to the working member 7 and the working member 7 will be described. The socket body 50 also has a through hole 52 and a recess 53. The through hole 52 passes through the socket body 50 along the axial intersection direction Da. The axial intersection direction Da intersects with respect to the central axis AX1. In this embodiment, the axial intersection direction Da is orthogonal to the central axis AX1. The working member 7 is disposed in the through hole 52 along the axial intersection direction Da. The recess 53 is recessed relative to the outer peripheral surface of the socket body 50 along the axial intersection direction Da. The elastic member 11 is disposed in the recess 53 along the axial intersection direction Da. The elastic member 11 is elastic. The elastic member 11 is, for example, a compression coil spring. The elastic member 11 expands and contracts along the axial intersection direction Da. The elastic member 11 is disposed between the working part 71 of the working member 7 and the bottom surface 53a of the recess 53. The elastic member 11 supports the working part 71.

[0068] The socket body 50 also has a pair of contact portions 54. Figure 3 and Figure 4 Only one contact portion 54 is shown in the diagram. In addition, the working member 7 also has a pair of connecting portions 72, a pair of limiting portions 73, an opening 74, and an axially opposing portion 75.

[0069] Define one side D1 and the other side D2 of the axis intersection direction Da. One side D1 represents the direction from the axially opposite part 75 toward the working part 71 (first direction) when the working member 7 is positioned in the through hole 52. The other side D2 represents the direction from the working part 71 toward the axially opposite part 75 (second direction) when the working member 7 is positioned in the through hole 52.

[0070] A pair of connecting portions 72 extend in the intersecting direction Da along the axes. The pair of connecting portions 72 connect the working portion 71 and the axially opposite portion 75. That is, the working portion 71 is connected to the axially opposite portion 75 via the pair of connecting portions 72. The connecting portions 72 are columnar. An opening 74 is defined by the working portion 71, the pair of connecting portions 72, and the axially opposite portion 75. The opening 74 opens along the axial direction AD1.

[0071] A pair of limiting portions 73 are disposed at both ends of the axially opposite portions 75 in the direction Db. Direction Db indicates a direction orthogonal to the direction intersecting the axis Da and the axial direction AD1. For example... Figure 3 As shown, with the working member 7 positioned in the through hole 52, a pair of limiting portions 73 are opposite to a pair of contact portions 54 in the axial intersection direction Da. Specifically, with the limiting portions 73 and contact portions 54 facing each other, the contact portions 54 are located on one side D1 of the limiting portion 73, and the limiting portion 73 is located on the other side D2 of the contact portions 54. The pair of contact portions 54 are opposite to each other in the direction Db. Furthermore, the through hole 52 is provided between the pair of contact portions 54.

[0072] With the working member 7 positioned in the through hole 52, the elastic member 11 pushes the working part 71 towards the side D1 in the axis crossing direction Da. In this case, the limiting part 73 of the working member 7 contacts the contact part 54 in the axis crossing direction Da. Therefore, the limiting part 73 prevents the working member 7 from disengaging from the through hole 52 towards the side D1 in the axis crossing direction Da. That is, the working member 7 remains in the socket body 50 while positioned in the through hole 52. Sometimes, the position of the working member 7 when the limiting part 73 is in contact with the contact part 54 is recorded as the "initial position".

[0073] On the other hand, with the working member 7 positioned in the through hole 52, if a force is applied to the working member 7 on the other side D2 of the axis crossing direction Da, the working member 7 moves from its initial position to the other side D2 of the axis crossing direction Da against the elastic force of the elastic member 11. When the force on the working member 7 is released, the working member 7 moves to the side D1 of the axis crossing direction Da due to the elastic force of the elastic member 11, until the limiting part 73 contacts the contact part 54. That is, the working member 7 returns to its initial position.

[0074] Next refer to Figure 3 and Figure 4 The insertion part 9 is inserted into the tube TB2. Specifically, the insertion part 9 has an insertion body 91, a connecting body 92, and a plurality of protrusions 93. The insertion body 91 is inserted into the tube TB2. The insertion body 91 has a cylindrical shape. The protrusions 93 protrude from the outer peripheral surface of the insertion body 91 toward the radially outward side of RD1. The protrusions 93 have an annular shape. The diameter of the protrusions 93 increases from the rear end 91a of the first connector 100 along the axial direction AD1 toward the front end 5a.

[0075] The connector 92 is connected to the insertion port 5. The connector 92 is connected to the rear end 91b of the insert 91 along the axial direction AD1. The connector 92 and the insert 91 are configured as a single component (one-piece molded article). The connector 92 has a cylindrical shape.

[0076] Next, refer to Figure 5 The internal structure of the first connector 100 will be described. Figure 5 It is along Figure 3 A cross-sectional view of the VV line. Figure 5 This shows the state where the first connector 100 and the second connector 200 are separated. That is, it shows the state where the first connector 100 is not connected to the second connector 200.

[0077] like Figure 5 As shown, the socket portion 5 also includes a connector 55, a socket valve portion 56, a rod portion 57, an elastic member 58, sealing members 59, 60, 61, and 65, a flow path 62, and a plug placement portion 63. Plug body 203 ( Figure 1The plug body 203 is disposed in the plug placement section 63. Specifically, the plug placement section 63 has a plug placement space 67. Furthermore, the plug body 203 is disposed in the plug placement space 67. Additionally, the plug placement section 63 has a protrusion placement section 66. The protrusion 204 of the plug body 203 ( Figure 1 The insertion portion 9 is disposed in the protrusion configuration portion 66. Furthermore, the insertion portion 9 also has a flow path 94. Additionally, the first connector body 1 also has a protrusion portion 64. Specifically, the insertion body 50 of the insertion portion 5 has a protrusion portion 64. Details of the protrusion portion 64 are described below.

[0078] Flow paths 94 and 62, and the plug configuration space 67 extend along the axial direction AD1. The front end of the axial direction AD1 of flow path 94 is connected to the rear end of the axial direction AD1 of flow path 62. That is, flow path 94 is connected to flow path 62. Furthermore, the front end of the axial direction AD1 of flow path 62 is connected to the rear end of the axial direction AD1 of plug configuration space 67. That is, flow path 62 is connected to plug configuration space 67. The front end of the axial direction AD1 of plug configuration space 67 is connected to opening 74. That is, plug configuration space 67 is connected to opening 74. Furthermore, opening 74 is connected to opening 51 along the axial direction AD1.

[0079] The connector 55 is connected to the protrusion 64 of the socket body 50. The protrusion 64 is located at the rear end of the socket body 50 along the axial direction AD1. The connector 55 and the socket body 50 are configured as a single component (one-piece molded article). The connector 55 has a cylindrical shape.

[0080] The connector 55 of the socket 5 is fitted into the connector 92 of the insertion part 9. As a result, the socket 5 is connected to the insertion part 9.

[0081] The spigot valve portion 56 has a cylindrical shape. The spigot valve portion 56 is disposed at the rear end of the plug housing space 67. The spigot valve portion 56 is pushed from the protrusion 64 side of the spigot body 50 towards the front end 5a side by the elastic member 58. The spigot valve portion 56 blocks the rear end of the plug housing space 67. A sealing member 65 is disposed in the plug housing space 67. The sealing member 65 is an elastic body and has an annular shape. The sealing member 65 contacts the outer peripheral surface of the spigot valve portion 56, thereby sealing the rear end of the plug housing space 67.

[0082] The rod portion 57 extends along the axial direction AD1. The front end portion 57a ​​of the rod portion 57 along the axial direction AD1 is disposed at the rear end portion of the plug configuration space 67. Figure 5In this example, the front end portion 57a ​​is disposed inside the socket valve portion 56. A sealing member 60 is mounted on the outer peripheral surface of the front end portion 57a. The sealing member 60 is an elastic body and has an annular shape. The sealing member 60 seals the area between the outer peripheral surface of the rod portion 57 and the inner peripheral surface of the socket valve portion 56. Furthermore, a sealing member 61 is disposed in the plug placement space 67. The sealing member 61 is disposed closer to the front end 5a of the socket body 50 than the sealing member 65.

[0083] An elastic member 58 is disposed in the flow path 62. The elastic member 58 is elastic. The elastic member 58 is, for example, a compression coil spring. A sealing member 59 is mounted on the outer peripheral surface of the connector 55. The sealing member 59 is an elastic body with an annular shape. The sealing member 59 seals the area between the outer peripheral surface of the connector 55 and the inner peripheral surface of the connector 92.

[0084] Next, refer to Figure 5 and Figure 6 The working component 7 will be described. Figure 5 The working member 7 is shown when the axially opposite part 75 is in the initial position Z0. For example... Figure 5 As shown, when the working member 7 (working part 71) is pressed down by the elastic member 11 towards the side D1 in the axial intersection direction Da and remains stationary, the axially opposing part 75 is located in the initial position Z0. In the initial position Z0, the axially opposing part 75 is opposite the protruding arrangement part 66 in the axial direction AD1. That is, in the initial position Z0, the axially opposing part 75 is located in front of the protruding arrangement part 66 in the axial direction AD1.

[0085] Figure 6 The working member 7 is shown when the axially opposite portion 75 is in the open position Z1. Figure 6 As shown, when an external force is applied to the working member 7 (working part 71) on the other side D2 of the axis crossing direction Da, the working member 7 (working part 71) is pushed against the elastic force of the elastic member 11 and remains stationary on the other side D2 of the axis crossing direction Da. As a result, the axially opposite part 75 moves from the initial position Z0 to the open position Z1 and remains stationary. In the open position Z1, the axially opposite part 75 is located on the other side D2 of the axis crossing direction Da, which is closer to the protruding part 66. Therefore, in the open position Z1, the axially opposite part 75 and the protruding part 66 are not opposite each other in the axial direction AD1. As a result, in the open position Z1, the protruding part 66 is open in front of the axial direction AD1. In addition, the "external force" is applied to the working member 7 (working part 71) by the operator, for example, by the operator pushing the working part 71 with their fingers.

[0086] Next, refer to Figure 7 The connection status of the first connector 100 and the second connector 200 is described. Figure 7This is a cross-sectional view showing the connection between the first connector 100 and the second connector 200. With the first connector 100 and the second connector 200 connected, the central axis AX1 of the first connector 100 coincides with the central axis AX2 of the second connector 200. Therefore, axial AD1 coincides with axial AD2, radial RD1 coincides with radial RD2, and circumferential CD1 coincides with circumferential CD2.

[0087] like Figure 7 As shown, the first connector 100 and the second connector 200 constitute the pipe connector 300. That is, the pipe connector 300 has the first connector 100 and the second connector 200.

[0088] If the plug body 203 is inserted into the socket body 50, the front end 203a of the plug body 203 along the axial AD1 direction contacts the front end 56a of the socket valve portion 56 along the axial AD1 direction. Therefore, the socket valve portion 56 moves from one side D11 to the other side D12 along the axial AD1 direction due to the plug body 203. Simultaneously, as the plug body 203 is inserted into the socket body 50, the front end 57a of the rod portion 57 along the axial AD1 direction contacts the front end 208b of the plug valve portion 208 along the axial AD1 direction. Therefore, the plug valve portion 208 moves from one side D12 to one side D11 along the axial AD1 direction. As a result, the flow path 213 of the plug portion 201 connects to the flow path 62 of the socket portion 5. Therefore, liquid flows between the first connector 100 and the second connector 200.

[0089] Next refer to Figure 7 The following describes the case where the connection state of the first connector 100 and the second connector 200 is switched between a locked state and an unlocked state. When the first connector 100 and the second connector 200 are connected, the plug body 203 is disposed in the plug placement portion 63 (plug placement space 67) of the connector body 50. In this case, the protrusion 204 of the plug body 203 is disposed in the protrusion placement portion 66.

[0090] The working member 7 is pushed by the elastic member 11 towards the side D1 in the axial intersection direction Da. Therefore, the axially opposing portion 75 of the working member 7 is located in the initial position Z0. As a result, the protrusion 204 of the plug body 203 and the axially opposing portion 75 face each other along the axial AD1 and are in contact. That is, in the initial position Z0, with the first connector body 1 already connected to the second connector 200, the axially opposing portion 75 is opposite the protrusion 204 protruding from the outer peripheral surface of the second connector 200 from the front end 5a side of the first connector body 1 along the axial AD1. Therefore, the connection state between the first connector 100 and the second connector 200 becomes a locked state.

[0091] On the other hand, if an external force is applied to the working part 71 on the other side D2 in the direction of axis intersection Da, the axially opposite part 75 moves from the initial position Z0 to the open position Z1. In the open position Z1, the axially opposite part 75 is not opposite the protrusion 204 in the axial direction AD1. As a result, the front of the protrusion 204 in the axial direction AD1 is open. Therefore, the connection state between the first connector 100 and the second connector 200 becomes an unlocked state. That is, the locking of the connection state between the first connector 100 and the second connector 200 is released. Therefore, the second connector 200 can be separated from the first connector 100. Additionally, the "external force" is applied to the working member 7 (working part 71) by the operator, for example, by the operator pushing the working part 71 with their fingers.

[0092] The above is for reference only. Figure 7 Explained, the working part 71 switches the relative and non-relative states of the axially opposite part 75 and the protrusion 204 on the axial AD1 by working along the cross direction Da of the axis.

[0093] Next, refer to Figure 4 , Figure 8 and Figure 9 The working component 7 will be described. Figure 8 This is a top view showing the first connector 100. Figure 9 It is along Figure 8 A cross-sectional view of line VIII-VIII.

[0094] like Figure 4 and Figure 8 As shown, the mounting member 3 has a cross-directional opposing portion 30. In this embodiment, the cross-directional opposing portion 30 has two opposing pieces 310. The two opposing pieces 310 are in the direction Db ( Figure 4 (relative to)

[0095] like Figure 9 As shown, the intersecting direction opposite portion 30 is in the relative state of the axial opposite portion 75 and the protrusion 204. Figure 7 The first connector body 1 and the working part 71 are positioned relative to each other along the axial cross direction Da. Therefore, according to this embodiment, the movement of the working part 71 in the axial cross direction Da is restricted by the cross direction opposing part 30. As a result, malfunction of the working part 71 can be suppressed. Therefore, it is possible to prevent the relative state between the axial opposing part 75 and the protrusion 204 from becoming non-opposing due to malfunction of the working part 71, and the connection state between the first connector 100 and the second connector 200 from becoming unlocked.

[0096] Specifically, the working part 71 consists of an elastic member 11 ( Figure 7It is pushed towards the side D1 in the direction of axis intersection Da. Furthermore, the intersecting direction opposing portion 30 is in the opposing state of the axial opposing portion 75 and the protrusion 204. Figure 7 The insertion body 50 and the working part 71 are positioned relative to each other along the axial direction Da. Therefore, the movement of the working part 71 to the other side D2 of the axial direction Da is restricted by the cross-direction opposing part 30.

[0097] In addition, such as Figure 9 As shown, the mounting component 3 is located at the first position P1 on the axial direction AD1. The first position P1 indicates the position of the cross-direction opposite part 30 relative to the working part 71 along the axial cross-direction Da.

[0098] Next, refer to Figure 10 and Figure 11 The case where the mounting component 3 is located in the second position P2 will be explained. Figure 10 This is a top view showing the first connector 100 when the mounting component 3 is in the second position P2. Figure 11 It is along Figure 10 A cross-sectional view along line XI-XI.

[0099] like Figure 10 and Figure 11 As shown, the mounting member 3 is located in the second position P2. The second position P2 indicates that the cross-direction opposing portion 30 is away from the first position P1 in the axial direction AD1. In other words, the second position P2 indicates that the cross-direction opposing portion 30 is away from the first position P1 in the axial direction AD1. Further, the second position P2 indicates that the cross-direction opposing portion 30 is not opposite the working portion 71 along the axial cross-direction Da. Therefore, when the mounting member 3 is in the second position P2, the movement of the working member 7 along the axial cross-direction Da is unrestricted. As a result, the operator can easily separate the second connector 200 from the first connector 100 by pushing the working portion 71 towards the other side D2 of the axial cross-direction Da, thereby releasing the lock established by the axial opposing portion 75.

[0100] In addition, in this embodiment, as an example, the position of the mounting member 3 (first position P1 and second position P2) is indicated by the position of the cross-direction opposite part 30 in the axial direction AD1.

[0101] Next, refer to Figures 8-11 The movement of the mounting member 3 will be described. The mounting member 3 is movable along the axis AD1 between a first position P1 and a second position P2. Therefore, according to this embodiment, by moving the mounting member 3 along the axis AD1 between the first position P1 and the second position P2, the operator can easily switch the connection state of the first connector 100 and the second connector 200 between a locked state and an unlocked state.

[0102] Furthermore, in this embodiment, such as Figure 9 and Figure 11 As shown, the first connector body 1 has a first limiting portion 80. Specifically, the socket body 50 has the first limiting portion 80. The first limiting portion 80 restricts the movement of the cross-direction opposing portion 30 between the first position P1 and the second position P2. Therefore, according to this embodiment, even if an unexpected force such as vibration is applied to the mounting member 3, the movement of the mounting member 3 from the first position P1 to the second position P2 can be suppressed. As a result, even if an unexpected force such as vibration is applied to the mounting member 3, the movement of the working member 7 in the axial cross-direction Da can be restricted by the cross-direction opposing portion 30. Therefore, malfunction of the working member 7 can be effectively suppressed, and the connection between the first connector 100 and the second connector 200 can be prevented from undesirably becoming unlocked.

[0103] Furthermore, in this embodiment, the first limiting portion 80 extends along the axial direction AD1 during cross-sectional observation. For example, the first limiting portion 80 has a wavy shape during cross-sectional observation. Figure 9 and Figure 11 In the example, the first limiting portion 80 has a first recess 81 and a protrusion 82. The first recess 81 is recessed inward toward the radial direction RD1 relative to the central axis AX1. The protrusion 82 is connected to the first recess 81. Furthermore, the protrusion 82 protrudes outward toward the radial direction RD1. Compared to the first recess 81, the protrusion 82 is further away from the working portion 71 in the axial direction AD1. That is, the protrusion 82 is located behind the first recess 81 in the axial direction AD1. According to this embodiment, the first limiting portion 80 can be realized with such a simple structure as the first recess 81 and the protrusion 82. Furthermore, as long as the shape of the mounting member 3 matches the shape of the first limiting portion 80, a simple structure of the mounting member 3 can be realized.

[0104] Specifically, the first concave portion 81 and the convex portion 82 each have an annular shape extending circumferentially along CD1. Furthermore, as... Figure 9 As shown, at the first position P1, the rear end 320 of the mounting member 3 along the axial AD1 is fitted into the first recess 81. Furthermore, the protrusion 82 is adjacent to the first recess 81 along the axial AD1. Therefore, it is possible to effectively suppress the mounting member 3 from moving from the first position P1 to the second position P2 due to vibration or other factors.

[0105] Furthermore, in this embodiment, the first limiting portion 80 also has a second recess 83. The second recess 83 is recessed radially inward (RD1). The second recess 83 is connected to the protrusion 82. Compared to the protrusion 82, the second recess 83 is further away from the working portion 71 in the axial direction AD1. That is, the second recess 83 is located further behind the protrusion 82 in the axial direction AD1. Furthermore, the first connector body 1 has a protrusion 64. The protrusion 64 protrudes to a position further outward (RD1) than the apex VT of the protrusion 82. That is, the maximum outer diameter R1 of the protrusion 64 is greater than or equal to the maximum outer diameter R2 of the protrusion 82. Figure 6 The protrusion 64 connects to the second recess 83 in the axial direction AD1. Compared to the second recess 83, the protrusion 64 is further away from the working part 71 in the axial direction AD1. That is, the protrusion 64 is located further rearward in the axial direction AD1 than the second recess 83. Therefore, according to this embodiment, as... Figure 11 As shown, when the mounting member 3 is in the second position P2, it is possible to suppress the mounting member 3 from dislodging rearward in the axial direction AD1.

[0106] Specifically, the second recess 83 and the protrusion 64 each have an annular shape extending circumferentially along CD1. Furthermore, as... Figure 11 As shown, at the second position P2, the rear end 320 of the mounting member 3 along the axial AD1 is fitted into the second recess 83. Furthermore, the protrusion 82 is adjacent to the second recess 83 along the axial AD1. Therefore, it is possible to effectively suppress the mounting member 3 from moving from the second position P2 to the first position P1 due to vibration or other factors.

[0107] Next, refer to Figure 8 , Figure 10 , Figure 12 and Figure 13 Another function of the mounting component 3 will be explained. Figure 12 This is a top view showing the mounting component 3. Figure 13 This is a perspective view showing mounting component 3. (For example...) Figure 12 and Figure 13 As shown, mounting component 3 also has a second limiting part 84. (As indicated...) Figure 8 As shown, with the mounting member 3 in the first position P1, the second limiting part 84 is opposite to the two end faces 710 of the working part 71 on the circumferential CD1. Therefore, the second limiting part 84 restricts the movement of the working part 71 in the circumferential CD1. As a result, according to this embodiment, it is possible to suppress the cross-direction opposing part 30 from being opposite to the working part 71 in the axial cross-direction Da. Therefore, it is possible to effectively suppress the malfunction of the working part 71.

[0108] Specifically, the second limiting part 84 has a pair of inclined surfaces 840. The inclined surfaces 840 are inclined relative to the central axis AX1. The pair of inclined surfaces 840 are opposite each other relative to the central axis AX1 from the front end 5a of the first connector body 1 toward the rear end 91a. Specifically, the pair of inclined surfaces 840 are inclined relative to the central axis AX1 from the front end 5a of the first connector body 1 toward the rear end 91a in a manner that brings them close to each other.

[0109] With the mounting component 3 in the first position P1, the inclined surface 840 is opposite to the end face 710 of the working part 71 in the circumferential direction CD1 and contacts the end face 710.

[0110] In particular, in this embodiment, such as Figure 8 and Figure 10 As shown, in the states where the mounting member 3 is in the first position P1 and the second position P2, the second limiting part 84 and the two end faces 710 on the circumferential CD1 of the working part 71 are opposite each other on the circumferential CD1. Therefore, according to this embodiment, even when the mounting member 3 is in the second position P2, deviation of the working part 71 from the circumferential CD1 can be suppressed. As a result, the operator's operation of the working part 71 becomes easier.

[0111] In addition, such as Figure 10 As shown, when the mounting member 3 is in the second position P2, the inclined surface 840 of the second limiting part 84 is separated from the end face 710 of the working part 71 in the circumferential direction CD1.

[0112] Next, refer to Figure 8 , Figure 12 and Figure 13 Another function of the mounting member 3 will be explained. The mounting member 3 has a pair of inclined surfaces 85. The inclined surfaces 85 are inclined relative to the central axis AX1. The pair of inclined surfaces 85 extend from the front end 5a of the first connector body 1 toward the rear end 91a relative to the central axis AX1. Therefore, according to this embodiment, it is easier for the operator to move the mounting member 3 from the first position P1 to the second position P2.

[0113] Next, refer to Figure 8 , Figure 12 and Figure 13 Another function of the mounting member 3 will be explained. The mounting member 3 has a pair of planes 86. The pair of planes 86 intersect the axis AD1. Therefore, according to this embodiment, it is easier for the operator to move the mounting member 3 from the second position P2 to the first position P1.

[0114] Next, refer to Figure 8 and Figure 12Another function of mounting member 3 will be explained. Mounting member 3 also has a third recess 88. The third recess 88 is recessed in the axial direction AD1. The elastic member 11 and the third recess 88 are in the axial intersection direction Da ( Figure 4 The components are arranged in an overlapping configuration. Furthermore, the elastic member 11 supports the working part 71 in the axial intersection direction Da. Therefore, according to this embodiment, contact between the elastic member 11 and the mounting member 3 can be suppressed. As a result, it is possible to suppress the elastic member 11 from detaching from the first connector body 1.

[0115] Specifically, the third recess 88 is recessed in the axial direction AD1 from the front end 5a of the first connector body 1 toward the rear end 91a. In addition, the third recess 88 is located between the socket body 50 and the working part 71.

[0116] Next, refer to Figure 4 and Figures 13-15 This section explains another function of the installation component 3. Figure 14 This is a rear view showing the mounting component 3. (As shown) Figure 13 and Figure 14 As shown, the mounting member 3 has a bent portion 87 and an opening 873. The bent portion 87 is bent along the circumferential direction CD1 relative to the central axis AX1. Figure 4 As shown, the curved portion 87 is fitted into the outer peripheral surface of the first connector body 1 (insert body 50). Therefore, according to this embodiment, the mounting member 3 can be easily installed on the first connector body 1, and the mounting member 3 can be easily removed from the first connector body 1. Furthermore, even when the protruding portion 64 is present, the mounting member 3 can be easily installed on the first connector body 1 (insert body 50).

[0117] Figure 15 This is a front view showing the first connector 100. (See attached image.) Figure 15 As shown, at the bend 87, the angle θ formed by one end 871 and the other end 872 of the circumferential direction CD1 of the bend 87 relative to the central axis AX1 is 230 degrees or more and 250 degrees or less. Therefore, according to this embodiment, the mounting member 3 can be more easily mounted on the first connector body 1 (plug body 50), and the mounting member 3 can be prevented from detaching from the first connector body 1 (plug body 50) due to vibration or the like.

[0118] like Figure 13 and Figure 14As shown, the curved portion 87 has a first facet 881 and a second facet 882. The first facet 881 is located at one end of the circumferential CD1 of the curved portion 87. The first facet 881 extends along the axial direction Da. The second facet 882 is located at the other end of the circumferential CD1 of the curved portion 87. The second facet 882 extends along the axial direction Da. The first facet 881 and the second facet 882 are parallel. Therefore, according to this embodiment, the opening 873 of the curved portion 87 is not curved and its width remains unchanged, thus making it easy to install the mounting member 3 onto the first connector body 1 (insertion body 50).

[0119] (Variation example)

[0120] Reference Figures 16-19 The first connector 100A of a variation of the first embodiment will be described. The main difference between this variation and the first embodiment lies in the rotation of the mounting member 3A along the circumferential direction CD1. Hereinafter, the differences between this variation and the first embodiment will be mainly explained.

[0121] Figure 16 This is a perspective view showing a modified example of the first embodiment, specifically the first connector 100A. Figure 16 As shown, the first connector 100A has a mounting member 3A. The mounting member 3A is mounted on the first connector body 1 (insertion body 50). The mounting member 3A is bent along the circumferential direction CD1. One end 21 and the other end 22 of the mounting member 3A are opposite each other on the circumferential direction CD1. One end 21 and the other end 22 of the mounting member 3A are located at a spaced interval on the circumferential direction CD1. Therefore, the mounting member 3A has a space SP between one end 21 and the other end 22.

[0122] Figure 17A This is a diagram showing the first position P1 of the mounting component 3A. Figure 17B This is a diagram showing the second position P2 of the mounting component 3A. Figure 18 This is a diagram showing the first connector 100A when the mounting component 3A is in the first position P1. Figure 19 This is a diagram showing the first connector 100A when the mounting component 3A is in the second position P2.

[0123] like Figure 17A and Figure 17B As shown, the mounting component 3A is rotatable between a first position P1 and a second position P2 along the circumferential direction CD1 relative to the central axis AX1. The first position P1 indicates the position where the intersecting part 30 is positioned relative to the working part 71 along the intersecting axial direction Da. Figure 18As shown, at the first position P1, the working part 71 and the cross-direction opposing part 30 are opposite each other in the axial cross-direction Da. Therefore, the cross-direction opposing part 30 restricts the movement of the working part 71 along the axial cross-direction Da. As a result, malfunction of the working member 7 can be suppressed. The second position P2 indicates the position where the cross-direction opposing part 30 moves away from the first position P1 in the circumferential direction CD1. Figure 19 As shown, at the second position P2, the working part 71 is opposite the space SP in the axis crossing direction Da. Therefore, the movement of the working part 71 along the axis crossing direction Da is unrestricted. As a result, the operator can easily unlock it by pushing the working member 7 towards the other side D2 of the axis crossing direction Da. In addition, the first position P1 and the second position P2 are separated in the circumferential direction CD1 relative to the central axis AX1.

[0124] The above is for reference only. Figures 16-19 Explained, according to this modified example, by rotating the mounting member 3A in the circumferential direction CD1, the connection state of the first connector 100A and the second connector 200 can be easily switched between a locked state and an unlocked state.

[0125] (Second Implementation)

[0126] Reference Figures 20 to 22 The first connector 2100 of the second embodiment of this disclosure will be described. Figure 20 and Figure 21 This is a cross-sectional view showing the first connector 2100 of the second embodiment. Figure 20 and Figure 21 This shows the state where the first connector 2100 and the second connector 200 are separated. Figure 20 The working component 2007 is shown in its initial position Z0. Figure 21 The working component 2007 is shown in the open position Z1.

[0127] In the first connector 100 of the first embodiment, the cross-direction opposing portion 30 of the mounting member 3 is opposite to the working portion 71 in the axial cross-direction Da between the first connector body 1 and the working portion 71. In contrast, in the first connector 2100 of the second embodiment, the mounting member 2003 has a mounting member protrusion 2003a disposed in the hole 2071a of the working portion 2071. Hereinafter, with regard to the second embodiment, matters that differ from the first embodiment will be described, and descriptions that are repeated in the first embodiment will be omitted.

[0128] The first connector 2100 includes a first connector body 2001, a mounting member 2003, a working part 2071, and an elastic member 2011. Specifically, the first connector 2100 includes a working member 2007. Furthermore, the working member 2007 includes a working part 2071. The working part 2071 includes a hole 2071a. The hole 2071a can extend along the axial direction AD1, and may penetrate the working part 2071 or not, for example, have a cylindrical shape.

[0129] The first connector body 2001 extends along the axial direction AD1. The first connector body 2001 is connected to the second connector 200 along the central axis AX1. The mounting member 2003 is mounted on the outer peripheral surface of the first connector body 2001. The working member 2007 is operated by the operator to switch the connection state between the first connector body 2001 and the second connector 200 between a locked state and an unlocked state. The elastic member 2011 supports the working member 2007. As an example, a button is formed by the working member 2007 (working part 2071) and the elastic member 2011.

[0130] Specifically, the first connector body 2001 has a socket portion 2005 and an insertion portion 9. The socket portion 2005 has a socket body 2050.

[0131] Next refer to Figure 20 and Figure 21 The structure related to the working member 2007 and the working member 2007 will be described. The socket body 2050 also has a receiving portion 2052. The receiving portion 2052 has a through hole on one side D1 of the socket body 2050 in the direction of intersection with the axis Da, and the inner circumference of the other side D2 of the socket body 2050 in the direction of intersection with the axis Da is recessed towards the direction of intersection with the axis Da. The working member 2007 is disposed in the receiving portion 2052 along the direction of intersection with the axis Da. An elastic member 2011 is disposed in the receiving portion 2052 along the direction of intersection with the axis Da. The elastic member 2011 is elastic. The elastic member 2011 is, for example, a compression coil spring. The elastic member 2011 expands and contracts along the direction of intersection with the axis Da. The elastic member 2011 is disposed between the working member 2007 and the bottom surface 2052a of the receiving portion 2052. The elastic member 2011 supports the working member 2007.

[0132] The working member 2007 also has a pair of connecting parts (not shown) and an axially opposing part 2075. The pair of connecting parts connect the working part 2071 and the axially opposing part 2075.

[0133] With the working member 2007 positioned in the receiving part 2052, the elastic member 2011 pushes the working part 2071 towards the side D1 in the axial intersection direction Da. At the initial position Z0, the axially opposing part 2075 and the protruding part 66 are opposite each other in the axial direction AD1. That is, at the initial position Z0, the axially opposing part 2075 is located in front of the protruding part 66 in the axial direction AD1. Therefore, the connection between the first connector 2100 and the second connector 200 is locked.

[0134] On the other hand, with the working member 2007 positioned in the receiving portion 2052, if a force is applied to the working member 2007 on the other side D2 of the axial intersection direction Da, the working member 2007 moves from the initial position Z0 to the other side D2 of the axial intersection direction Da against the elastic force of the elastic member 2011. As a result, the axially opposing portion 2075 moves from the initial position Z0 to the open position Z1 and remains stationary. In the open position Z1, the axially opposing portion 2075 is located on the other side D2 of the axial intersection direction Da, relative to the protruding configuration portion 66. Therefore, in the open position Z1, the axially opposing portion 2075 and the protruding configuration portion 66 are not opposite each other in the axial direction AD1. As a result, in the open position Z1, the protruding configuration portion 66 is open in front in the axial direction AD1. Therefore, the connection state between the first connector 2100 and the second connector 200 becomes an unlocked state.

[0135] If the force on the working member 2007 is released, the working member 2007 will move towards the side D1 in the direction of the axis intersection Da due to the elastic force of the elastic member 2011. That is, the working member 2007 returns to the initial position Z0.

[0136] The above is for reference only. Figure 20 and Figure 21 Explained, the working part 2071 switches the relative and non-relative states of the axially opposite part 2075 and the protrusion 204 on the axial AD1 by working along the cross direction Da of the axis.

[0137] Reference Figures 20 to 22 The first connector 2100 of the second embodiment will be described. Figure 22 This is a cross-sectional view showing the first connector 2100 of the second embodiment. Figure 22 This shows the state where the first connector 2100 and the second connector 200 are separated. Figure 22 The working component 2007 is shown in its initial position Z0.

[0138] like Figures 20 to 22As shown, the mounting member 2003 has a mounting member protrusion 2003a. The mounting member protrusion 2003a is an example of a mounting member limiting part. The shape of the mounting member protrusion 2003a is not particularly limited, as long as it can be inserted into the hole 2071a, for example, it can be cylindrical.

[0139] The mounting member protrusion 2003a is disposed in the hole 2071a of the working part 2071 when the axially opposing part 2075 and the protrusion 204 are in a relative state. Therefore, according to the second embodiment, the movement of the working part 2071 in the axial cross direction Da is restricted by the mounting member protrusion 2003a. As a result, malfunction of the working part 2071 can be suppressed. Therefore, it is possible to prevent the relative state of the axially opposing part 2075 and the protrusion 204 from becoming non-opposing due to malfunction of the working part 2071, and the connection state of the first connector 2100 and the second connector 200 from becoming unlocked.

[0140] Furthermore, the mounting member 2003 is located at a first position P1 along the axial direction AD1. The first position P1 indicates the position where the mounting member protrusion 2003a is positioned within the hole 2071a. Furthermore, the first position P1 indicates... Figure 22 The location of the installation component 2003.

[0141] On the other hand, the mounting member 2003 is located in the second position P2. The second position P2 indicates a position where the mounting member protrusion 2003a is displaced axially AD1 from the first position P1. In other words, the second position P2 indicates a position where the mounting member protrusion 2003a is displaced rearward axially AD1 relative to the first position P1. Further, in other words, the second position P2 indicates a position where the mounting member protrusion 2003a is not positioned within the hole 2071a. Furthermore, the second position P1 indicates... Figure 20 and Figure 21 The position of the mounting member 2003 is determined by the position of the mounting member 2003. Therefore, when the mounting member 2003 is in the second position P2, the movement of the working member 2007 along the axial cross direction Da is unrestricted. As a result, the operator can easily separate the second connector 200 from the first connector 2100 by pushing the working part 2071 towards the other side D2 of the axial cross direction Da to release the lock provided by the axially opposite part 2075.

[0142] In addition, in the second embodiment, as an example, the position of the mounting member 2003 (first position P1 and second position P2) is indicated by the position of the mounting member protrusion 2003a in the axial direction AD1.

[0143] Next, the movement of the mounting member 2003 will be described. The mounting member 2003 is movable along the axial direction AD1 between a first position P1 and a second position P2. Therefore, according to the second embodiment, by moving the mounting member 2003 along the axial direction AD1 between the first position P1 and the second position P2, the operator can easily switch the connection state of the first connector 2100 and the second connector 200 between a locked state and an unlocked state.

[0144] (Third implementation method)

[0145] Reference Figure 23 and Figure 24 The first connector 3100 of the third embodiment of this disclosure will be described. Figure 23 and Figure 24 This is a cross-sectional view showing the first connector 3100 of the third embodiment. Figure 23 and Figure 24 This shows the state where the first connector 3100 and the second connector 200 are separated. Figure 23 The working component 3007 is shown in the initial position Z0 and the mounting component 3003 is shown in the first position P1. Figure 24 The working component 3007 in the open position Z1 and the mounting component 3003 in the second position P2 are shown.

[0146] In the first connector 2100 of the second embodiment, the mounting member 2003 has a mounting member protrusion 2003a disposed in the hole 2071a of the working part 2071. In contrast, in the first connector 3100 of the third embodiment, the mounting member 3003 has a cover portion 3003a disposed further outward of the radial RD1 outer surface of the working part 3071. Hereinafter, with regard to the third embodiment, matters that differ from the second embodiment will be described, and descriptions that are repeated in the second embodiment will be omitted.

[0147] The first connector 3100 includes a first connector body 3001, a mounting member 3003, a working part 3071, and an elastic member 3011. Specifically, the first connector 3100 includes a working member 3007. Furthermore, the working member 3007 includes a working part 3071.

[0148] The first connector body 3001 extends along the axial direction AD1. The first connector body 3001 is connected to the second connector 200 along the central axis AX1. The mounting member 3003 is mounted on the outer peripheral surface of the first connector body 3001. The working member 3007 is operated by the operator to switch the connection state between the first connector body 3001 and the second connector 200 between a locked state and an unlocked state. The elastic member 3011 supports the working member 3007. As an example, a button is formed by the working member 3007 (working part 3071) and the elastic member 3011.

[0149] Specifically, the first connector body 3001 has a socket portion 3005 and an insertion portion 9. The socket portion 3005 has a socket body 3050.

[0150] Next refer to Figure 23 and Figure 24 The structure related to the working member 3007 and the working member 3007 will be described. The socket body 3050 also has a receiving portion 3052. The receiving portion 3052 has a through hole on one side D1 of the socket body 3050 in the direction of intersection of the axes Da, and the inner circumference of the other side D2 of the socket body 3050 in the direction of intersection of the axes Da is recessed towards the direction of intersection of the axes Da. The working member 3007 is disposed in the receiving portion 3052 along the direction of intersection of the axes Da. The elastic member 3011 is disposed in the receiving portion 3052 along the direction of intersection of the axes Da. The elastic member 3011 is disposed between the working member 3007 and the bottom surface 3052a of the receiving portion 3052.

[0151] The working member 3007 also has a pair of connecting parts (not shown) and an axially opposing part 3075. The pair of connecting parts connect the working part 3071 and the axially opposing part 3075.

[0152] With the working member 3007 positioned in the receiving portion 3052, the elastic member 3011 pushes the working portion 3071 towards the side D1 in the axial intersection direction Da. At the initial position Z0, the axially opposing portion 3075 and the protruding arrangement portion 66 are opposite each other in the axial direction AD1. That is, at the initial position Z0, the axially opposing portion 3075 is located in front of the protruding arrangement portion 66 in the axial direction AD1. Therefore, the connection between the first connector 3100 and the second connector 200 is locked. Furthermore, at the initial position Z0, the radially RD1 outer surface of the working member 3007 is approximately coplanar with the radially RD1 outer surface of the first connector body 3001. Alternatively, the radially RD1 outer surface of the working member 3007 can be configured to be radially RD1 inner than the radially RD1 outer surface of the first connector body 3001.

[0153] On the other hand, with the working member 3007 positioned in the receiving portion 3052, if a force is applied to the working member 3007 on the other side D2 of the axial intersection direction Da, the working member 3007 moves from the initial position Z0 to the other side D2 of the axial intersection direction Da against the elastic force of the elastic member 3011. As a result, the axially opposing portion 3075 moves from the initial position Z0 to the open position Z1 and remains stationary. In the open position Z1, the axially opposing portion 3075 is located on the other side D2 of the axial intersection direction Da, relative to the protruding configuration portion 66. Therefore, in the open position Z1, the axially opposing portion 3075 and the protruding configuration portion 66 are not opposite each other in the axial direction AD1. As a result, in the open position Z1, the protruding configuration portion 66 is open in front in the axial direction AD1. Therefore, the connection state between the first connector 3100 and the second connector 200 becomes an unlocked state.

[0154] If the force on the working member 3007 is released, the working member 3007 will move to the side D1 in the direction of the axis intersection Da due to the elastic force of the elastic member 3011. That is, the working member 3007 returns to the initial position Z0.

[0155] The above is for reference only. Figure 23 and Figure 24 Explained, the working part 3071 switches the relative and non-relative states of the axially opposite part 3075 and the protrusion 204 on the axial AD1 by working along the axial cross direction Da.

[0156] like Figure 23 and Figure 24 As shown, the mounting member 3003 has a cover portion 3003a. The cover portion 3003a is an example of a mounting member limiting portion. The cover portion 3003a is, for example, a plate-like body.

[0157] In the relative state of the axially opposing portion 3075 and the protrusion 204, the cover portion 3003a is configured to be further outward of the radial RD1 outer side than the radially RD1 outer side of the working portion 3071. That is, the cover portion 3003a covers the radially RD1 outer side of the working portion 3071. Therefore, according to the third embodiment, contact with the working portion 3071 is prevented by the cover portion 3003a. In other words, according to the third embodiment, the movement of the working portion 3071 in the axial cross direction Da is restricted by the cover portion 3003a. As a result, malfunction of the working portion 3071 can be suppressed. Therefore, it is possible to prevent the relative state of the axially opposing portion 3075 and the protrusion 204 from becoming non-opposing due to malfunction of the working portion 3071, and the connection state of the first connector 3100 and the second connector 200 from becoming unlocked.

[0158] Furthermore, the mounting member 3003 is located at a first position P1 along the axial direction AD1. The first position P1 indicates the position of the cover portion 3003a relative to the working portion 3071 along the axial direction Da. Furthermore, the first position P1 indicates... Figure 23 The position of the mounting component 3003.

[0159] On the other hand, the mounting member 3003 is located in the second position P2. The second position P2 indicates the position where the cover 3003a is away from the first position P1 in the axial direction AD1. In other words, the second position P2 indicates the position where the cover 3003a is away from the first position P1 in the axial direction AD1. Further, the second position P2 indicates the position where the cover 3003a is not opposite the working part 3071 in the direction Da that intersects the axis. Furthermore, the second position P2 indicates... Figure 24 The position of the mounting member 3003 is such that when the cover 3003a is in the second position P2, contact with the working member 3007 is unobstructed. As a result, the operator can easily separate the second connector 200 from the first connector 3100 by pushing the working part 3071 towards the other side D2 of the axial cross direction Da to release the lock made by the axially opposite part 3075.

[0160] In addition, in the third embodiment, as an example, the position of the mounting member 3003 (first position P1 and second position P2) is indicated by the position of the cover 3003a in the axial direction AD1.

[0161] Next, the movement of the mounting member 3003 will be described. The mounting member 3003 is movable along the axial direction AD1 between a first position P1 and a second position P2. Therefore, according to the third embodiment, by moving the mounting member 3003 along the radially outer surface of the socket body 3050 along the axial direction AD1 between the first position P1 and the second position P2, the operator can easily switch the connection state of the first connector 3100 and the second connector 200 between a locked state and an unlocked state.

[0162] (Fourth Implementation)

[0163] Reference Figures 25 to 27 The first connector 4100 of the fourth embodiment of this disclosure will be described. Figure 25 and Figure 26 This is a cross-sectional view showing the first connector 4100 of the fourth embodiment. Figure 25 and Figure 26 This shows the state where the first connector 4100 and the second connector 200 are separated. Figure 25 The working component 4007 is shown in the initial position Z0 and the mounting component 4003 is shown in the first position P1. Figure 26The working component 4007 is shown in the open position Z1 and the mounting component 4003 is shown in the second position P2.

[0164] In the first connector 3100 of the third embodiment, at the first position P1, the inner surface of the cover 3003a in the radial direction RD1 contacts the outer surface of the working part 3071 in the radial direction RD1. Conversely, in the fourth connector 4100 of the fourth embodiment, at the first position P1, the inner surface of the cover 4003a in the radial direction RD1 is spatially separated from the outer surface of the working part 4071 in the radial direction RD1. Hereinafter, the fourth embodiment will describe the differences from the third embodiment, omitting descriptions that overlap with the third embodiment.

[0165] The first connector 4100 includes a first connector body 4001, a mounting member 4003, a working part 4071, and an elastic member 4011. Specifically, the first connector 4100 includes a working member 4007. Furthermore, the working member 4007 includes a working part 4071.

[0166] The first connector body 4001 extends along the axial direction AD1. The first connector body 4001 is connected to the second connector 200 along the central axis AX1. The mounting member 4003 is mounted on the outer peripheral surface of the first connector body 4001. The working member 4007 is operated by the operator to switch the connection state between the first connector body 4001 and the second connector 200 between a locked state and an unlocked state. The elastic member 4011 supports the working member 4007. As an example, a button is formed by the working member 4007 (working part 4071) and the elastic member 4011.

[0167] Specifically, the first connector body 4001 has a socket portion 4005 and an insertion portion 9. The socket portion 4005 has a socket body 4050.

[0168] Next refer to Figure 25 The structure related to the working member 4007 and the working member 4007 will be described. The socket body 4050 also has a receiving portion 4052. The receiving portion 4052 has a through hole on one side D1 of the socket body 4050 in the direction of intersection of the axes Da, and the inner circumference of the other side D2 of the socket body 4050 in the direction of intersection of the axes Da is recessed towards the direction of intersection of the axes Da. The working member 4007 is disposed in the receiving portion 4052 along the direction of intersection of the axes Da. The elastic member 4011 is disposed in the receiving portion 4052 along the direction of intersection of the axes Da. The elastic member 4011 is disposed between the working member 4007 and the bottom surface 4052a of the receiving portion 4052.

[0169] The working member 4007 also has a pair of connecting parts (not shown) and an axially opposing part 4075. The pair of connecting parts connect the working part 4071 and the axially opposing part 4075.

[0170] With the working member 4007 positioned in the receiving portion 4052, the elastic member 4011 pushes the working portion 4071 towards the side D1 in the axial intersection direction Da. At the initial position Z0, the axially opposing portion 4075 and the protruding arrangement portion 66 are opposite each other in the axial direction AD1. That is, at the initial position Z0, the axially opposing portion 4075 is located in front of the protruding arrangement portion 66 in the axial direction AD1. Therefore, the connection between the first connector 4100 and the second connector 200 is locked. Furthermore, at the initial position Z0, the radially outer surface of the working member 4007 is positioned radially outer than the radially outer surface of the first connector body 4001.

[0171] On the other hand, with the working member 4007 positioned in the receiving portion 4052, if a force is applied to the working member 4007 on the other side D2 of the axial intersection direction Da, the working member 4007 moves from the initial position Z0 to the other side D2 of the axial intersection direction Da against the elastic force of the elastic member 4011. As a result, the axially opposing portion 4075 moves from the initial position Z0 to the open position Z1 and remains stationary. In the open position Z1, the axially opposing portion 4075 is located on the other side D2 of the axial intersection direction Da, relative to the protruding configuration portion 66. Therefore, in the open position Z1, the axially opposing portion 4075 and the protruding configuration portion 66 are not opposite each other in the axial direction AD1. As a result, in the open position Z1, the protruding configuration portion 66 is open in front in the axial direction AD1. Therefore, the connection state between the first connector 4100 and the second connector 200 becomes an unlocked state.

[0172] If the force on the working member 4007 is released, the working member 4007 will move to the side D1 in the direction of axis intersection Da due to the elastic force of the elastic member 4011. That is, the working member 4007 returns to the initial position Z0.

[0173] The above is for reference only. Figure 25 and Figure 26 Explained, the working part 4071 switches the relative and non-relative states of the axially opposite part 4075 and the protrusion 204 on the axial AD1 by working along the axial cross direction Da.

[0174] like Figure 25 and Figure 26 As shown, the mounting member 4003 has a cover portion 4003a. The cover portion 4003a is an example of a mounting member limiting portion. The cover portion 4003a is, for example, a plate-like body.

[0175] The cover portion 4003a is configured such that, in the relative state of the axially opposing portion 4075 and the protrusion 204, it is further outward than the radially outer side of the working portion 4071. That is, the cover portion 4003a covers the radially outer side of the working portion 4071. Therefore, according to the fourth embodiment, the cover portion 4003a prevents contact with the working portion 4071. In other words, according to the fourth embodiment, the cover portion 4003a restricts the movement of the working portion 4071 in the axial cross direction Da. As a result, malfunction of the working portion 4071 can be suppressed. Therefore, it is possible to prevent the relative state of the axially opposing portion 4075 and the protrusion 204 from becoming non-opposing due to malfunction of the working portion 4071, and the connection state of the first connector 4100 and the second connector 200 from becoming unlocked.

[0176] Furthermore, the mounting member 4003 is located at a first position P1 along the axial direction AD1. The first position P1 indicates the position of the cover 4003a relative to the working part 4071 along the axial direction Da. Specifically, at the first position P1, the inner radial surface RD1 of the cover 4003a is spatially separated from the outer radial surface RD1 of the working part 4071. Furthermore, the first position P1 indicates... Figure 25 The position of the mounting component 4003.

[0177] On the other hand, the mounting member 4003 is located in the second position P2. The second position P2 indicates the position where the cover 4003a is away from the first position P1 in the axial direction AD1. In other words, the second position P2 indicates the position where the cover 4003a is away from the first position P1 in the axial direction AD1. Further, the second position P2 indicates the position where the cover 4003a is not opposite the working part 4071 in the direction Da that intersects the axis. Furthermore, the second position P2 indicates... Figure 26 The position of the mounting member 4003 is such that when the cover 4003a is in the second position P2, contact with the working member 4007 is unobstructed. As a result, the operator can easily separate the second connector 200 from the first connector 4100 by pushing the working part 4071 towards the other side D2 in the axial cross direction Da to release the lock made by the axially opposite part 4075.

[0178] In addition, in the fourth embodiment, as an example, the position of the mounting member 4003 (first position P1 and second position P2) is indicated by the position of the cover 4003a in the axial direction AD1.

[0179] Next, the movement of the mounting member 4003 will be described. The mounting member 4003 is movable along the axial direction AD1 between a first position P1 and a second position P2. Therefore, according to the fourth embodiment, by moving the mounting member 4003 along the axial direction AD1 between the first position P1 and the second position P2, the operator can easily switch the connection state of the first connector 4100 and the second connector 200 between a locked state and an unlocked state. Furthermore, even if the cover 4003a is bent due to external force, contact with the working part 4071 can be suppressed, and malfunction of the working part 4071 can be prevented.

[0180] Next, refer to Figure 27 The other functions of the mounting component 4003 will be explained. Figure 27 This is a sectional view showing the mounting component 4003. (See attached image.) Figure 27 As shown, the mounting member 4003 also has a movement limiting portion 4084. The movement limiting portion 4084 is, for example, a pair of sidewalls. The pair of sidewalls extend from the ends of the cover portion 4003a along the axial intersection direction Da. Specifically, when the mounting member 4003 is in the first position P1, the movement limiting portion 4084 is opposite to the two end faces 4710 on the circumferential CD1 of the working portion 4071. Therefore, the movement limiting portion 4084 restricts the movement of the mounting member 4003 in the circumferential CD1. As a result, according to the fourth embodiment, it is possible to prevent the cover portion 4003a from being opposite to the working portion 4071 in the axial intersection direction Da. Therefore, it is possible to effectively suppress the malfunction of the working portion 4071.

[0181] Furthermore, when the mounting member 4003 is in the first position P1, the movement restriction part 4084 is opposite to the end face 4710 of the working part 4071 in the circumferential direction CD1 and contacts the end face 4710.

However, this disclosure is not limited to the above embodiments and can be implemented in various ways without departing from its spirit. Furthermore, multiple structural elements disclosed in the above embodiments can be appropriately modified.

[0195] (10) In any of (3) to (9) of the first joint, the mounting member further has a second limiting portion that restricts the circumferential movement of the working part relative to the central axis. The second limiting portion is opposite to the two end faces of the working portion in the circumferential direction.

[0196] (11) In the first connector described in (10), in the state where the mounting member is in the first position and in the state where the mounting member is in the second position, the second limiting portion is opposite to the two end faces of the working portion in the circumferential direction.

The mounting member also has a third recess that is recessed towards the axial direction. The elastic member and the third recess are arranged overlapping in the axial intersecting direction and support the working part in the axial intersecting direction.

[0200] (15) In the first joint described in (2), the mounting member is rotatable between a first position and a second position along a circumferential direction relative to the central axis. The first position refers to the position of the cross-direction opposing part relative to the working part in the cross-axis direction. The second position indicates the position where the opposite part in the intersecting direction moves away from the first position in the circumferential direction.
