A rotating shaft located inside the pipe insertion hole, having an opening that is disposed and communicates with the pipe insertion hole, and is parallel to the central axis of the pipe insertion hole and spaced radially from the center of the pipe insertion hole And a retainer that is rotatable between a temporarily fixed position and a locked position. The retainer can be rotated from the temporary fixing position toward the locked position by inserting the pipe from the pipe insertion hole to a normal depth in the connector main body at the temporary fixing position.

  According to the present invention, when the pipe is inserted into the connector main body to the normal depth at the temporary fixing position, the retainer can be rotated. Therefore, if the insertion depth of the pipe is shallower than the normal depth, the retainer cannot be rotated, so it can be checked by rotation of the retainer whether the pipe has been reliably inserted. Then, by arranging the retainer inside the connector body, the connector is made compact in the radial direction of the pipe insertion hole, and the retainer is rotated around the connector body by rotating the retainer within the connector body. Requires little space for. Therefore, the connection work with the pipe can be suitably performed even in a limited space. Further, the retainer is arranged inside the connector body and rotated within the connector body, so that the retainer does not protrude from the outer surface of the connector body except for a part for operating the rotation of the retainer. Therefore, it is possible to reduce the possibility that the retainer is deformed or broken due to contact with other components. Thereby, connection workability | operativity and handling property can be improved.

In addition, the relationship between the axial direction of the pipe insertion part 4 and the axial direction of the hose connection part 5 is not limited to orthogonal, for example, the pipe insertion part 4 and the hose connection part 5 are arranged on one axis. Also good. A fluid passage (not shown) is formed through the connector body 1 so as to penetrate therethrough. The material of the connector body 1 is, for example, resin.

  The retainer accommodating portion 6 has a hollow cylindrical shape, and a pipe insertion hole 11 into which the pipe 50 is inserted is provided on the front surface thereof. Here, the diameter of the pipe insertion hole 11 is larger than the diameter of a spool portion 51 described later of the pipe 50. A hose (not shown) is extrapolated to the hose connection portion 5. Hereinafter, the side where the retainer accommodating portion 6 is provided is referred to as one end side, and the side where the hose connecting portion 5 is provided is referred to as the other end side. The pipe 50 is inserted into the pipe insertion portion 4 from the one end side toward the other end side.

  Here, the pipe 50 is made of a metal such as aluminum or a synthetic resin, and as shown in FIG. 1, a spool portion (annular convex portion) 51 is provided on the outer periphery of the end portion.

  As shown in FIG. 2, which is a cross-sectional view taken along the line AA of FIG. 1, the pipe insertion portion 4 has a pipe accommodation hole 15 provided on the other end side (the back side in the drawing) with respect to the retainer 2. The pipe accommodation hole 15 communicates with the pipe insertion hole 11 through an opening 31 (to be described later) of the retainer 2 and accommodates the tip end portion of the pipe 50 inserted from the pipe insertion hole 11. In FIG. 2, the retainer 2 is not shown. The diameter of the pipe receiving hole 15 is slightly larger than the diameter of the pipe 50 and smaller than the diameter of the spool portion 51. Further, the center of the pipe accommodation hole 15 coincides with the center of the pipe insertion hole 11.

  The pipe insertion portion 4 includes a contact wall 16 that is provided radially outward of the pipe accommodation hole 15 and faces the pipe insertion hole 11 with the retainer 2 interposed therebetween. The abutting wall 16 is located on the other end side (the back side of the drawing) of the retainer 2, which will be described later. When the pipe 50 is inserted into the pipe insertion portion 4 to the normal depth, the surface 51a (see FIG. 1) on the other end side of the spool portion 51 comes into contact with the contact wall 16.

  In addition, the pipe insertion portion 4 is provided with an accommodation groove 17 provided on the other end side (the back side of the drawing) from the contact wall 16 and formed in the radial direction of the pipe accommodation hole 15 (radial direction of the pipe insertion hole 11). Have. When the retainer 2 is positioned at the temporary fixing position, the accommodating groove 17 can accommodate a protrusion 34 described later of the retainer 2. The protrusion 34 accommodated in the accommodation groove 17 can move in the radial direction of the pipe accommodation hole 15 and cannot move in the circumferential direction of the pipe accommodation hole 15. Therefore, the retainer 2 cannot rotate while the protrusion 34 is received in the receiving groove 17.

  In addition, the pipe insertion portion 4 has an arc groove 18 provided radially outward of the pipe accommodation hole 15 with respect to the accommodation groove 17. The arc groove 18 is formed in an arc shape in the B direction along the circumferential direction of the pipe accommodation hole 15 (circumferential direction of the pipe insertion hole 11), and one end communicates with the accommodation groove 17.

  Here, as will be described later, the protrusion 34 of the retainer 2 housed in the housing groove 17 at the temporary fixing position is caused by the spool 51 when the pipe 50 is inserted into the pipe insertion part 4 to the normal depth. The housing hole 15 is moved outward in the radial direction. The arc groove 18 accommodates the protrusion 34 that has been moved radially outward of the pipe accommodation hole 15 by the spool portion 51 so as to be movable in the circumferential direction of the pipe accommodation hole 15. The retainer 2 can be rotated in the B direction by accommodating the projection 34 accommodated in the accommodation groove 17 in the arc groove 18.

  Further, the pipe insertion portion 4 has a concave portion 19 provided on the outer surface of the retainer accommodating portion 6. When the retainer 2 is positioned at the lock position, a lock claw 36 (to be described later) of the retainer 2 is engaged with the recess 19. The rotation of the retainer 2 is locked by engaging the lock claw 36 with the recess 19.

  Moreover, the pipe insertion part 4 has the retainer accommodation groove | channel 20 in which the retainer main body 32 mentioned later of the retainer 2 fits rotatably, and the fixed block 21 engage | inserted by the retainer accommodation part 6. FIG. The retainer receiving groove 20 is provided on one end side (the front side in the drawing) of the contact wall 16. The fixed block 21 can be attached to and detached from the retainer accommodating portion 6. When the connector 100 is assembled, the retainer 2 is inserted into the retainer housing 6 from the direction C with the fixed block 21 removed. The retainer 2 is accommodated in the retainer accommodating portion 6 by fitting the retainer main body 32 into the retainer accommodating groove 20 while accommodating the protrusion 34 in the accommodating groove 17. Thereafter, the retainer 2 is prevented from coming out of the retainer accommodating portion 6 by fitting the fixed block 21 into the retainer accommodating portion 6.

  Note that a convex portion (not shown) is formed on the side surface (a surface parallel to the paper surface) of the fixed block 21, and this convex portion is fitted into a concave portion (not shown) formed on the side surface forming the retainer housing portion 6. Thus, the fixed block 21 is not easily detached from the retainer accommodating portion 6. Further, a gap 22 is formed between the pipe insertion portion 4 and the fixed block 21, and the fixed block 21 can be easily removed from the retainer accommodating portion 6 by inserting a tool into the gap 22. Has been.

  The pipe insertion portion 4 has a guide groove 23 formed along the C direction and communicating with the accommodation groove 17. The guide groove 23 passes through the pipe accommodation hole 15 in the axial direction (direction orthogonal to the paper surface), and the protrusion 34 is inserted into the accommodation groove 17 when the retainer 2 is inserted into the retainer accommodation portion 6 from the C direction. To guide. Thereby, the projection part 34 can be easily accommodated in the accommodation groove 17.

  The pipe insertion portion 4 has a wall portion 24 that is provided on each of one end side and the other end side of the recess 19 and protrudes radially outward from the pipe insertion hole 11 and the pipe accommodation hole 15. When the locking claw 36 is engaged with the concave portion 19, the locking claw 36 is positioned inside the end surface of the wall portion 24 in the radial direction of the pipe insertion hole 11 and the pipe accommodation hole 15. Therefore, the lock claw 36 does not protrude from the outer surface of the pipe insertion portion 4.

  Although not shown, a seal member such as an O-ring is placed in the pipe insertion portion 4. Therefore, a seal member such as an O-ring is positioned between the tip end of the pipe 50 accommodated in the pipe accommodation hole 15 and the outer wall of the pipe insertion portion 4. This seal member prevents liquid such as fuel from leaking.

<Retainer>
Next, the retainer 2 will be described with reference to FIGS. The retainer 2 is a part having a role for confirming from outside whether or not the pipe 50 is completely connected to the connector main body 1, and as shown in FIG. 1, the retainer accommodating portion of the pipe insertion portion 4. 6 has an opening 31 that communicates with the pipe insertion hole 11. The retainer 2 is disposed between the temporary fixing position and the lock position around the rotation axis that is parallel to the central axis of the pipe insertion hole 11 and radially separated from the center of the pipe insertion hole 11 in the retainer accommodating portion 6. It can be rotated with. The material of the retainer 2 is, for example, resin or metal.

  As shown in FIG. 3 which is a front view, a top view, and a side view, the retainer 2 has a ring-shaped retainer body 32 in which an opening 31 communicating with the pipe insertion hole 11 is provided eccentrically. Here, the diameter of the opening 31 is substantially the same as the diameter of the pipe insertion hole 11 and is slightly larger than the diameter of the spool 51. The center O of the retainer main body 32 is located on the rotation axis of the retainer 2. The center O ′ of the opening 31 coincides with the center of the pipe insertion hole 11 in the temporary fixing position, but is eccentric from the center O of the retainer main body 32, so that the retainer 2 moves toward the lock position in the B direction. The more it is rotated, the more it is displaced from the center of the pipe insertion hole 11. Therefore, when the retainer 2 is rotated from the temporary fixing position toward the lock position in a state where the pipe 50 is inserted into the pipe insertion portion 4 to the normal depth, the retainer main body is interposed between the spool portion 51 and the pipe insertion hole 11. A part of 32 will be located. Since a part of the retainer main body 32 is positioned between the spool portion 51 and the pipe insertion hole 11, the spool portion 51 cannot pass through the pipe insertion hole 11.

  The retainer 2 has a checker portion 33 provided on the other end side of the retainer main body 32. The checker portion 33 is formed integrally with the retainer main body 32, and is elastically deformable in the radial direction of the opening 31 by being separated from the retainer main body 32 and extending along the circumferential direction of the opening 31. Yes.

  The retainer 2 has a protrusion 34 that protrudes from the checker portion 33 along the axial direction of the opening 31 toward the other end. The protrusion 34 is located at the tip of the checker 33, and is accommodated in the accommodation groove 17 until the pipe 50 is inserted to the pipe insertion portion 4 to the normal depth at the temporary fixing position. Then, when the pipe 50 is inserted into the pipe insertion part 4 to the normal depth at the temporary fixing position, the spool part 51 in contact with the protrusion part 34 presses the protrusion part 34 outward in the radial direction of the opening part 31, When the checker 33 is elastically deformed radially outward of the opening 31, the protrusion 34 is moved radially outward of the opening 31 (pipe housing hole 15) and is accommodated in the arc groove 18. . The protrusion 34 can be moved in the circumferential direction of the pipe receiving hole 15 by being received in the arc groove 18. As a result, the retainer 2 can rotate from the temporarily fixed position toward the locked position.

  The retainer 2 has a lock lever 35 that is provided on the outer peripheral surface of the retainer main body 32 and extends in a direction (B direction) in which the retainer 2 rotates toward the lock position. The lock lever 35 is formed integrally with the retainer main body 32, is bent in a square shape, and can be elastically deformed in the radial direction of the opening 31.

  The retainer 2 has a lock claw 36 that protrudes from the tip of the lock lever 35 toward the opening 31. The lock claw 36 protrudes toward the retainer accommodating portion 6 in a state where the retainer 2 is accommodated in the retainer accommodating portion 6. The lock claw 36 engages with the recess 19 provided on the outer surface of the retainer housing 6 when the retainer 2 is positioned at the lock position.

  In addition, the retainer 2 has an operation portion 37 that is operated by an operator at a bent portion of the lock lever 35. The operation portion 37 protrudes from the outer surface of the pipe insertion portion 4 to facilitate the operation by the operator. The surface of the operation unit 37 is subjected to anti-slip processing composed of fine irregularities.

(Movement of each part of the connector when connecting a pipe to the connector)
Next, the movement of each component of the connector 100 when the pipe 50 is connected to the connector 100 will be described with reference to FIG.

<Before pipe insertion>
Before the pipe 50 is inserted into the pipe insertion portion 4, as shown in FIG. 4A, the retainer 2 is located at the temporary fixing position, and the protrusion 34 of the retainer 2 is accommodated in the accommodation groove 17. Has been. Since the retainer 2 cannot rotate while the protruding portion 34 is accommodated in the accommodating groove 17, the retainer 2 is temporarily fixed until the pipe 50 is inserted into the pipe insertion portion 4 to the normal depth at the temporary fixing position. be able to.

<Pipe insertion>
The pipe 50 is inserted into the pipe insertion part 4 from the pipe insertion hole 11 in a state where the retainer 2 is located at the temporary fixing position. When the insertion depth of the pipe 50 reaches the normal depth, the surface 51a (see FIG. 1) on the other end side of the spool portion 51 abuts against the abutment wall 16, whereby the insertion of the pipe 50 is stopped. Further, as shown in FIG. 4B, the spool portion 51 comes into contact with the protruding portion 34 received in the receiving groove 17 and presses the protruding portion 34 radially outward of the pipe receiving hole 15. The checker portion 33 is elastically deformed, and the projection portion 34 is moved radially outward of the pipe housing hole 15 to be accommodated in the arc groove 18. Thereby, the retainer 2 can be rotated in the B direction.

  In this way, when the pipe 50 is inserted into the pipe insertion portion 4 to the normal depth at the temporary fixing position, the retainer 2 can be rotated. Therefore, if the insertion depth of the pipe 50 is shallower than the normal depth, the retainer 2 cannot be rotated. Therefore, it can be checked by the rotation of the retainer 2 whether the pipe 50 is securely inserted.

  From this state, as shown in FIG. 4C, the retainer 2 is rotated in the direction of the lock position (direction B). The retainer 2 can be suitably rotated by the operator operating the operation portion 37 protruding from the outer surface of the pipe insertion portion 4.

  When the retainer 2 is rotated toward the lock position, the center of the opening 31 is displaced from the center of the pipe insertion hole 11, so that a part of the retainer main body 32 is positioned between the spool portion 51 and the pipe insertion hole 11. . Thereby, since the spool part 51 cannot pass through the pipe insertion hole 11, it is possible to prevent the pipe 50 from coming off from the pipe insertion part 4. Furthermore, if the retainer 2 is rotated even a little toward the lock position, a part of the retainer main body 32 is positioned between the spool portion 51 and the pipe insertion hole 11 so that the pipe 50 cannot be easily removed, and the connection work is performed. Since it is not necessary to keep pushing (holding) the pipe 50 until completion, the workability of pipe connection can be improved. Furthermore, since the retainer 2 positioned at the temporary fixing position can only rotate in the direction of the lock position and cannot rotate in the reverse direction, it is difficult to make a mistake in the rotation direction of the retainer 2 during connection work, and the rotation direction is incorrect. It is possible to prevent the retainer 2 from being deformed or broken.

  Then, when the retainer 2 is rotated to the lock position, the lock claw 36 is engaged with the recess 19. Thereby, since the rotation of the retainer 2 is locked, the pipe 50 can be held in the pipe insertion portion 4 in a state of being prevented from coming off.

  Further, when the lock claw 36 is engaged with the recess 19, the lock claw 36 is positioned inside the end surface of the wall portion 24 in the radial direction of the pipe insertion hole 11 and the pipe receiving hole 15. It does not protrude from the outer surface of part 4. Thereby, since it becomes impossible to touch the lock claw 36 easily, the lock claw 36 can be made difficult to come off from the recess 19.

  Here, in the present embodiment, the retainer 2 is disposed in the pipe insertion portion 4 so that the connector 100 is made compact in the radial direction of the pipe insertion hole 11, and the retainer 2 is placed in the pipe insertion portion 4. By rotating at, almost no space is required for rotating the retainer 2 around the pipe insertion portion 4. Therefore, the connection work with the pipe 50 can be suitably performed even in a limited space. Further, the retainer 2 protrudes from the outer surface of the pipe insertion portion 4 except for a portion for operating the rotation of the retainer 2 by arranging the retainer 2 inside the pipe insertion portion 4 and rotating in the pipe insertion portion 4. There is no. Therefore, it is possible to reduce the possibility that the retainer 2 is deformed or broken in contact with other components. Thereby, connection workability | operativity and handling property can be improved.

  When removing the pipe 50 from the pipe insertion portion 4 for maintenance or the like, a tool or the like is inserted between the wall portions 24 to remove the lock claw 36 from the recess 19. When the retainer 2 is rotated to the temporary fixing position, the center of the opening 31 coincides with the center of the pipe insertion hole 11 so that the spool portion 51 can pass through the pipe insertion hole 11. When the pipe 50 is pulled out from the pipe insertion portion 4, the protrusion 34 accommodated in the arc groove 18 moves inward in the radial direction of the pipe insertion hole 11 and is accommodated in the accommodation groove 17. Stopped.
