[0080] Figure 1 It is a perspective view of the connector device in a mating state according to the embodiment. Figure 2 It is a perspective view of the connector device after the mating state according to the embodiment is released.

[0081] In the following embodiments, for ease of explanation, the mating and unmating directions of the two connectors 2 and 3 are set to Z (Z1, Z2) directions, the direction perpendicular to the Z direction and in which the cable 4 extends is set to X (X1, X2) directions, and the direction perpendicular to the X and Z directions is set to Y (Y1, Y2) directions. The Z2 direction is the mating direction, and the Z1 direction is the unmating direction. In addition, each direction is used to illustrate the relative positional relationship of the parts constituting the connector device 1, and does not represent an absolute direction. Sometimes, the Y direction is also referred to as the left and right directions, in particular, the Y1 direction is referred to as the left direction or the Y1 side is relatively referred to as the left side, and the Y2 direction is referred to as the right direction or the Y2 side is relatively referred to as the right side. Sometimes, in the Z direction, the Z1 side is relatively referred to as the top or the upper side, the top, and the Z2 side is relatively referred to as the bottom, the lower side, the bottom or the bottom side.

[0082] like Figure 1 and Figure 2 As shown, the connector device 1 includes a plug connector 2 and a socket connector 3. The plug connector 2 is used by connecting to one end of a cable 4, and the socket connector 3 is used by being set on the surface of a housing of other devices such as a motor. In this embodiment, it can be set on a servo motor for industrial equipment. The plug connector 2 and the socket connector 3 are push-in connectors. That is, the plug connector 2 and the socket connector 3 are mated with each other by pushing in the Z2 direction, so that the terminals of the two connectors 2 and 3 are electrically connected to each other. In other words, the push-in connector does not include a connector that ensures mating and electrical connection of the terminals by screwing.

[0083] Figure 3 is a top view of the connector device, Figure 4 yes Figure 3 AA section view.

[0084] like Figure 1 to Figure 4 As shown in FIG. 1 , the plug connector 2 is configured to include a first housing 20, an operating lever 21, a clamp receiving portion 22, a clamp 23, a clamping member 25, and a terminal. The clamp 23 fixes the cable 4 to the plug connector 2 via the clamp receiving portion 22 and the clamping member 25 fixed to the first housing 20. The clamp receiving portion 22 is fixed to the first housing 20 (for example, see FIG. 1 ) by a fixing member such as a screw 51 in a state where an elastic annular sealing member 50 such as rubber is sandwiched at its end in the X2 direction. Figure 4 ).like Figure 1 , Figure 2 and Figure 4 As shown in FIG. 1 , the clamp 23 is a cylindrical member made of an insulating material such as resin. The clamping member 25 is a cylindrical member made of an insulating material such as resin. Figure 4As shown, one end of the clamping member 25 is embedded in the recessed portion 22a provided at the end of the clamp receiving portion 22 in the X1 direction, and the clamp 23 is embedded from the periphery of the clamping member 25. The cable 4 is fixed to the first housing 20 by screwing or the like while passing the clamping member 25 and the clamp 23. In the present embodiment, two cables, namely, a power cable and a signal cable, are provided in the connector device 1 as the cables 4. However, the type and number of the cables 4 are not particularly limited.

[0085] The first housing 20 is made of a conductor, and here, it is a metal die casting formed in a box-shaped manner. A fitting portion 31 of the socket connector 3, which will be described later, is fitted inside the first housing 20. An inclined portion is formed on the inner wall 20a of the first housing 20 so that the internal space of the first housing 20 expands toward the end 20b of the first housing 20 into which the fitting portion 31 is inserted. An inclined portion 20h is formed at the corner where the inner wall 20a of the first housing 20 intersects with the end 20b. The inclined portion 20h can press the elastic member 39, which will be described later, of the socket connector 3 to compress the elastic member 39.

[0086] An internal fitting portion is provided inside the first shell 20, and the internal fitting portion accommodates a terminal electrically connected to the cable 4. The internal fitting portion includes an internal shell 201 provided in the first shell 20 and a terminal (not shown) held in the internal shell 201. The internal shell 201 is an insulating member such as resin, for example, and holds the terminal. The internal shell 201 can hold the terminal in a hole (not shown) provided in the internal shell 201 by pressing, or can hold the terminal by integral molding. The terminal is a conductor electrically connected to the terminal of the socket connector 3. In the present embodiment, the terminal includes a power terminal and a signal terminal. Therefore, two left and right internal shells 201 are provided inside the first shell 20. The power terminal is held in the internal shell 201 on the left, and the signal terminal is held in the internal shell 201 on the right. The internal fitting portion (or the left and right internal housings 201) respectively has a convex portion 201a including a power supply terminal and a signal terminal and extending in the Z2 direction, and the convex portion 201a is fitted with a corresponding concave portion 301a of the internal housing 301 of the plug-type connector 3 described later, so that the terminals of the two connectors 2 and 3 are electrically connected to each other (refer to Figure 4 ).

[0087] A hook portion 20d extending in the left-right direction and protruding from the front surface 20c is provided on the front surface 20c of the first housing 20, and a rotation shaft 20f is provided along the Y direction near the center of the left and right side surfaces 20e of the first housing 20.

[0088] like Figure 1 as well as Figure 2As shown, the operating lever 21 has a U-shape extending from one side surface 20e to the other side surface 20e of the first housing 20 and along the shape of the first housing 20, and can maintain the mating state of the plug connector 2 and the receptacle connector 3, and can release the mating state.

[0089] Specifically, the operating lever 21 includes a cover portion 211 extending in the Y direction, and a pair of arm portions 212 extending from both ends of the cover portion 211 toward the rotation shaft 20f and covering the left and right side surfaces 20e. The cover portion 211 is provided to maintain the mating state of the two connectors 2 and 3. Figure 1 As shown in FIG. 1 , the front surface 20c of the first housing 20 is covered, and when the mating state of the two connectors 2 and 3 is released, Figure 2 As shown, the upper surface 20g of the first housing 20 is covered.

[0090] The arm portion 212 is provided with a bearing portion 212b having an axial hole 212a. The rotation shaft 20f is inserted through the axial hole 212a, and the operating rod 21 is rotatably supported relative to the first housing 20. The operating rod 21 can rotate around the rotation shaft 20f by a predetermined angle (for example, 90°). Figure 1 The position of the mating state shown (hereinafter also referred to as the "first position") is Figure 2 The illustrated fitting state is released from the position (hereinafter also referred to as the "second position"), and conversely, the fitting state can be rotated from the second position to the first position.

[0091] like Figure 2 As shown, a cam groove 212c is provided in the arm portion 212. When the two connectors 2 and 3 are mated, the cam groove 212c engages with the later-described raised portion 34 of the socket connector 3 by the rotation of the operating lever 21, and the operating lever 21 is fixed to the later-described second housing 30 of the socket connector 3, and the plug connector 2 is locked relative to the socket connector 3. In addition, the cam groove 212c is formed in a manner that a part of the outer side of the arm portion 212 is recessed. That is, the arm portion 212 branches off from the cover portion 211 to form a bearing portion 212b and an arm 212d, and when the operating lever 21 rotates, the edge of the arm 212d slides in contact with the raised portion 34.

[0092] The cover portion 211 is provided with a claw portion 211a which is elastic and protrudes inward. When the operating rod 21 is lowered to the bottom, that is, when the operating rod 21 is located at the first position, the claw portion 211a is hooked on the hook portion 20d provided on the front side 20c of the first shell 20 to prevent unnecessary rotation of the operating rod 21.

[0093] Figure 5 It is a partially exploded perspective view of a socket connector.

[0094] The receptacle connector 3 includes a second housing 30 , a protrusion 35 , an annular groove 36 , a sealing member 37 , an elastic member 39 , an inner housing 301 , and a terminal 302 .

[0095] The second housing 30 is made of a conductor, and is, for example, a metal die-casting. The second housing 30 can be grounded. The second housing 30 includes a fitting portion 31 , a flange portion 32 , a locking wall portion 33 , and a protruding portion 34 .

[0096] like Figure 5 As shown, the fitting portion 31 has a cylindrical shape and is provided to extend in the Z direction. The end of the fitting portion 31 on the Z1 side is the front end, and the end on the Z2 side is the rear end. Figure 2 as well as Figure 4 As shown, the fitting portion 31 is fitted into the interior of the first housing 20 from the front end side. The outer shape of the fitting portion 31 is a rectangular shape with rounded corners when viewed from above. That is, the outer wall constituting the fitting portion 31 has a rectangular shape with rounded corners when viewed from above. In addition, the outer shape of the fitting portion 31 is slightly smaller than that of the first housing 20 when viewed from above, and a gap is provided between the outer periphery of the fitting portion 31 and the inner wall 20a of the first housing 20.

[0097] like Figure 5 As shown, a through hole 311 penetrating in the Z direction is provided inside the fitting portion 31, and a wall 312 is provided in the through hole 311 to divide the space into left and right sides. Therefore, at the through hole 311, through holes 311a and 311b are formed on the left and right sides due to the wall 312. The internal housing 301 is accommodated in the through holes 311a and 311b.

[0098] The internal housing 201 is made of an insulating member such as resin, and holds the terminal 302. The terminal 302 is a conductor electrically connected to the terminal of the plug connector 2. In this embodiment, the terminal 302 includes a power terminal, a signal terminal, and a ground terminal. The power terminal is a terminal electrically connected to the power cable 4. The signal terminal is a terminal electrically connected to the signal cable 4. The ground terminal is a terminal connected to the ground. In this embodiment, the power terminal and the ground terminal are held in the left side of the internal housing 301, and the signal terminal is held in the right side of the internal housing 301. Figure 4 As shown, the inner housing 301 has a recessed portion 301a at the end portion on the Z1 side, and the protruding portions 201a of the plug connector 2 are respectively fitted into the recessed portions 301a. Thus, the terminals of the two connectors 2 and 3 can be electrically connected.

[0099] The flange portion 32 extends outward from the rear end portion (i.e., the end portion on the Z2 side of the fitting portion 31) on the opposite side of the front end portion of the fitting portion 31 into which the other connector, i.e., the plug connector 2, is inserted (i.e., the end portion on the Z1 side of the fitting portion 31). In other words, the flange portion 32 has a rectangular shape when viewed from above. The flange portion 32 is a portion for fixing the socket connector 3 to a device to which the socket connector 3 is to be installed. In the present embodiment, threaded holes 32a are provided at the four corners of the flange portion 32, and the socket connector 3 can be fixed to the device to which the socket connector 3 is to be installed by inserting and tightening fixing members such as screws not shown in the figure into the above-mentioned threaded holes 32a. When the first shell 20 is fitted with the fitting portion 31 and pushed in the Z2 direction, the end portion 20b of the first shell 20 approaches or abuts against the upper surface of the flange portion 32 via the elastic member 39 (refer to Figure 4 ). A plurality of protrusions 32b protruding toward the Z1 direction are formed on the surface on the Z1 direction side of the flange portion 32 located around the fitting portion 31, that is, on the upper surface. In the present embodiment, two protrusions 32b are formed on the two long sides of the rectangular shape of the flange portion 32. The protrusions 32b can abut against the elastic member 39 in the X direction to compress the elastic member 39.

[0100] The locking arm portion 33 is erected on the flange portion 32 in the extension direction (Z1 direction) of the fitting portion 31. In the present embodiment, the locking wall portion 33 is a pair of plate-like bodies, and is provided on the flange portion 32 in such a manner that its plane is parallel to the ZX direction and sandwiches the fitting portion 31. Here, the locking wall portion 33 is arranged on the outer side of the outer wall of the fitting portion 31 constituting the short side of the rectangle when viewed from above. The front end portion (Z1 side end portion) of the locking wall portion 33 is formed in a tapered shape.

[0101] The raised portion 34 is a protrusion extending from the end of the Z1 side of the pair of locking wall portions 33 toward the mating portion 31 side. The cross-sectional shape of the raised portion 34 is a tapered shape that becomes thinner as it approaches the flange portion 32 side. When the operating rod 21 descends due to rotation, the raised portion 34 enters and engages with the cam groove 212c. That is, the raised portion 34 is located on the arm 212d and is in sliding contact with the upper edge of the arm 212d, so that the elastic member 39 can be compressed by applying a force (force in the Z2 direction) toward the flange portion 32 to the other connector, that is, the plug connector 2, through the arm 212d (operating rod 21). In this way, the two connectors 2 and 3 are mated together, forming a state in which the plug connector 2 is locked to the socket connector 3, and forming a state in which the mating state is maintained. The position in which the above state is formed is the first position. On the other hand, when the operating rod 21 rises by a predetermined angle, the protrusion 34 is disengaged from the cam groove 212c, thereby releasing the locking relationship with the cam groove 212c (arm 212d), and forming a state after the interlocking state is released. The position in which the above state is formed is the second position. That is, by the rotation of the operating rod 21, the bearing portion 212b is slidably mounted on the tapered upper portion of the locking wall portion 33. In addition, after the plug connector 2 is locked, the front end of the arm 212d protruding to the side of the bearing portion 212b is hooked on the edge of the protrusion 34, thereby strengthening the locking state of the operating rod 21.

[0102] like Figure 5 As shown, the protrusion 35 is provided on the outer periphery of the fitting portion 31 and bulges outward from the fitting portion 31. Specifically, the protrusion 35 has an inclined portion that tapers toward the front end side of the fitting portion 31 into which the plug connector 2 is inserted. When the protrusion 35 is fitted with the plug connector 2 of the other connector, the inner wall 20a of the second housing 30 is contacted (see FIG. Figure 4 ). Therefore, since the fitting portion 31 is grounded, the first housing 20 can also be grounded.

[0103] The annular groove 36 is provided on the outer periphery of the fitting portion 31 and is provided on the flange portion 32 side rather than the protrusion 35. Here, the annular groove 36 is a groove provided on the rear end side of the fitting portion 31 in an annular shape around the fitting portion 31.

[0104] The sealing member 37 is an elastic member such as rubber having elasticity. The sealing member 37 is annular and is embedded in the annular groove 36. The sealing member 37 is, for example, a gasket. The thickness of the sealing member 37 is such that the sealing member 37 is embedded in the annular groove 36 and protrudes outward from the protrusion 35 in the unloaded state. In other words, the outer shape of the sealing member 37 is similar to the shape of the fitting portion 31 when viewed from above, and is slightly larger than the fitting portion 31 including the protrusion 35. Figure 4As shown, when the first shell 20 is engaged with the engaging portion 31, the sealing member 37 is compressed inward by the inner wall 20a of the first shell 20 and is tightly attached to the inner wall 20a of the first shell 20 over the entire circumference. In addition, since the sealing member 37 is compressed, the inner wall 20a of the first shell 20 is in physical contact with the protrusion 35.

[0105] like Figure 4 As shown, the elastic member 39 is provided at the boundary portion between the fitting portion 31 and the flange portion 32. Specifically, the elastic member 39 is mounted on the periphery of the joint portion between the fitting portion 31 and the flange portion 32, and is formed of a member having elasticity such as rubber. The elastic member 39 is an annular body surrounding the end portion on the Z2 direction side, i.e., the bottom side, of the fitting portion 31. The elastic member 39 is provided on one side of the flange portion 32 relative to the sealing member 37. The elastic member 39 is sandwiched between the first housing 20 and the fitting portion 31 and / or the flange portion 32 when the plug connector 2 and the socket connector 3 are fitted, thereby suppressing the looseness between the first housing 20 and the fitting portion 31 and / or the flange portion 32.

[0106] [Function, Effect]

[0107] (1) The connector of the present embodiment is a connector (socket connector 3) that is mated with a counterpart connector (plug connector 2) by push-in. The counterpart connector includes a first housing 20 and an operating rod 21 rotatably supported on the first housing 20. The connector and the counterpart connector are locked by rotation of the operating rod 21. The connector includes a second housing 30. The second housing 30 has a mating portion 31 for mating the first housing 20 to the outside. The second housing 30 has a flange portion 32 and a mating portion 31 erected on the flange portion 32. An elastic member 39 is provided at a boundary between the flange portion 32 and the mating portion 31. The elastic member 39 suppresses looseness between the first housing 20 and the mating portion 31 and / or the flange portion 32 when the connector and the counterpart connector are mated.

[0108] Thus, during mating, by compressing the elastic member 39 disposed at the boundary between the flange portion 32 and the mating portion 31, looseness between the first housing 20 and the mating portion 31 and / or the flange portion 32 can be suppressed, and the relative positional relationship of the connector with respect to the other connector can be stabilized. In addition, after mating, the claw portion 211a of the operating rod 21 can be reliably hooked with the hook portion 20d of the first housing 20 by the rebound force of the elastic member 39, thereby preventing looseness. In addition, the looseness of the gap between the shaft hole 212a of the operating rod 21 and the rotating shaft 20f of the first housing 20 is lifted unilaterally by the rebound force of the elastic member 39, which can also prevent looseness. In this way, it is possible to prevent the continuous application of load on the rotating shaft 20f from causing wear and damage.

[0109] (2) The elastic member 39 is sandwiched between the first housing 20 and the fitting portion 31 and / or the flange portion 32 when the connector is mated with the mating connector. Thus, since the elastic member 39 is sandwiched between the first housing 20 and the fitting portion 31 and the flange portion 32, looseness can be suppressed and the looseness can be suppressed from being transmitted to the locking means, so that the relative position relationship of the connector with respect to the mating connector can be made more stable.

[0110] (3) The elastic member 39 is an annular body surrounding the fitting portion 31. Thus, the elastic member 39 can be easily manufactured and mounted.

[0111] (4) A plurality of protrusions 32b protruding toward the fitting portion 31 are formed on the surface of the flange portion 32 on the side close to the fitting portion 31. The protrusions 32b abut against the elastic member 39 in a direction perpendicular to the fitting direction of the connector and the mating connector to compress the elastic member 39. Thus, the elastic member 39 can be compressed by the protrusions 32b in the X direction to suppress looseness. In addition, the non-protruding portions between the plurality of protrusions 32b become the released portions of the compressed elastic member 39, which can prevent the elastic member 39 from being damaged due to excessive compression load.

[0112] (5) The flange portion 32 extends outward from the rear end portion of the mating portion 31 on the opposite side of the front end portion into which the other connector (plug connector 2) is inserted. The flange portion 32 is provided with a locking wall portion 33 and a raised portion 34. The locking wall portion 33 is erected in the extending direction of the mating portion 31. The raised portion 34 extends from the locking wall portion 33 to one side of the mating portion 31. The arm portion 212 of the operating lever 21 is provided with a cam groove 212c. When the connector is mated with the other connector, the raised portion 34 is engaged with the cam groove 212c by the rotation of the operating lever 21 to apply a force toward the flange portion 32 to the other connector, thereby compressing the elastic member 39. In this way, mating with the other connector can be assisted. That is, in the connector device 1 that is mated by pushing, it is sometimes not easy to insert to the inside by human strength. Even in such a case, by rotating the operating lever 21, the raised portion 34 engages with the cam groove 212c provided on the arm portion 212 of the operating lever 21, and the operating lever 21 provides a force to pull the other connector into the connector (socket connector 3), thereby assisting the mating. In addition, by compressing the elastic member 39 using the end portion 20b of the first housing 20 of the other connector, both looseness of the end portion 20b and the flange portion 32 and looseness of the mating portion 31 can be suppressed.

[0113] (6) The connector includes an annular groove 36 provided on the outer periphery of the fitting portion 31 and provided at a position close to the flange portion 32; and an annular sealing member 37 which is embedded in the annular groove 36 and has elasticity, and an elastic member 39 which is provided on the flange portion 32 side relative to the sealing member 37. Thus, the sealing member 37 can ensure waterproof performance. In addition, the elastic member 39 can suppress loosening of both the flange portion 32 and the fitting portion 31.

[0114] (7) The connector device 1 of the present embodiment includes: a plug connector 2, the plug connector 2 includes a first housing 20 and an operating rod 21 rotatably supported on the first housing 20; and a socket connector 3, the socket connector 3 includes a second housing 30, the second housing 30 has a fitting portion 31 that fits with the first housing 20, the plug connector 2 and the socket connector 3 are fitted together by push-fitting, and the plug connector 2 and the socket connector 3 are locked by rotating the operating rod 21, the second housing 30 has a flange portion 32 and a fitting portion 31 erected on the flange portion 32, and an elastic member 39 is provided on one of the plug connector 2 and the socket connector 3 at a boundary between the flange portion 32 and the fitting portion 31, and the elastic member 39 suppresses looseness between the first housing 20 and the fitting portion 31 and / or the flange portion 32 when the plug connector 2 and the socket connector 3 are fitted together.

[0115] Thus, when mating, by compressing the elastic member 39 provided on one of the plug connector 2 and the socket connector 3 at the boundary between the flange 32 and the mating portion 31, the looseness between the first housing 20 and the mating portion 31 and / or the flange 32 can be suppressed, and the relative positional relationship of the socket connector 3 with respect to the plug connector 2 can be stabilized. In addition, after mating, the claw 211a of the operating rod 21 can be reliably hooked with the hook portion 20d of the first housing 20 by the rebound force of the elastic member 39, thereby preventing looseness. In addition, the looseness of the gap between the shaft hole 212a of the operating rod 21 and the rotating shaft 20f of the first housing 20 is lifted up unilaterally by the rebound force of the elastic member 39, and looseness can also be prevented. In this way, it is possible to prevent the rotation shaft 20f from being continuously loaded and causing wear and damage.

[0116] (8) The elastic member 39 is sandwiched between the first housing 20 and the fitting portion 31 and / or the flange portion 32 when the plug connector 2 and the receptacle connector 3 are mated. Thus, since the elastic member 39 is sandwiched between the first housing 20 and the fitting portion 31 and the flange portion 32, looseness can be suppressed and the looseness can be suppressed from being transmitted to the locking means, so that the relative positional relationship of the receptacle connector 3 with respect to the plug connector 2 can be made more stable.

[0117] (9) The elastic member 39 is an annular body surrounding the fitting portion 31. Thus, the elastic member 39 can be easily manufactured and mounted.

[0118] (10) A plurality of protrusions 32b protruding toward the fitting portion 31 are formed on the surface of the flange portion 32 on the side close to the fitting portion 31. The protrusions 32b abut against the elastic member 39 in a direction perpendicular to the fitting direction of the plug connector 2 and the receptacle connector 3 to compress the elastic member 39. Thus, the elastic member 39 can be compressed by the protrusions 32b in the X direction to suppress looseness. In addition, the non-protruding portions between the plurality of protrusions 32b serve as the released portions of the compressed elastic member 39, and thus the elastic member 39 can be prevented from being damaged due to an excessive compressive load.

[0119] (11) The flange portion 32 extends outward from the rear end portion of the fitting portion 31 on the opposite side to the front end portion into which the plug connector 2 is inserted. The flange portion 32 is provided with a locking wall portion 33 and a raised portion 34. The locking wall portion 33 is erected in the extending direction of the fitting portion 31. The raised portion 34 extends from the locking wall portion 33 toward the fitting portion 31. The arm portion 212 of the operating lever 21 is provided with a cam groove 212c. When the plug connector 2 is fitted with the receptacle connector 3, the raised portion 34 is engaged with the cam groove 212c by the rotation of the operating lever 21 to apply a force toward the flange portion 32 to the plug connector 2, thereby compressing the elastic member 39. In this way, the fitting with the plug connector 2 can be assisted. That is, in the connector device 1 that is fitted by push-in, it is sometimes difficult to insert to the inner side by human strength. Even in such a case, by rotating the operating lever 21, the raised portion 34 engages with the cam groove 212c provided on the arm portion 212 of the operating lever 21, and the operating lever 21 provides a force to pull the plug connector 2 into the receptacle connector 3, thereby assisting the mating. In addition, by compressing the elastic member 39 using the end portion 20b of the first housing 20 of the plug connector 2, both looseness of the end portion 20b and the flange portion 32 and looseness of the mating portion 31 can be suppressed.

[0120] (12) The receptacle connector 3 includes an annular groove 36 provided on the outer periphery of the fitting portion 31 and provided at a position close to the flange portion 32, and an annular sealing member 37 which is inserted into the annular groove 36 and has elasticity, and an elastic member 39 which is provided on the flange portion 32 side relative to the sealing member 37. Thus, the sealing member 37 can ensure waterproof performance. In addition, the elastic member 39 can suppress loosening of both the flange portion 32 and the fitting portion 31.

[0121] (13) A sloped portion 20h for pressing the elastic member 39 is formed at a corner where the inner wall 20a of the first housing 20 intersects with the end portion 20b of the first housing 20 into which the fitting portion 31 is inserted. Thus, the elastic member 39 can be reliably compressed by pressing the elastic member 39 with the sloped portion 20h. In this case, the elastic member 39 is held at the sloped portion 20h and may or may not enter between the end portion 20b and the flange portion 32.

[0122] (14) The first housing 20 is provided with a rotating shaft 20f, and the operating rod 21 is provided with an axial hole 212a through which the rotating shaft 20f is inserted. By inserting the rotating shaft 20f into the axial hole 212a, the operating rod 21 can rotate between a first position for maintaining the mating state between the plug connector 2 and the socket connector 3 and a second position for releasing the mating state. Thus, the looseness of the gap between the axial hole 212a of the operating rod 21 and the rotating shaft 20f of the first housing 20 is lifted up unilaterally by the rebound force of the elastic member 39, and the looseness can be prevented. In this way, it is possible to prevent the rotating shaft 20f from being continuously loaded and thus being worn or damaged.
