Has been inserted. In this state, the male member 80 is replaced with the female member 82.
When inserted into the housing 81, the ring-shaped protrusion 80a of the male member 80 pushes the claw portion 83a of the locking member 83 outward in the radial direction against its elasticity and passes through the claw portion 83a. As a result, the tip of the claw portion 83a and the ring-shaped protrusion 80
When a is locked, the male member 80 and the female member 82 are brought into a coupled state. In this combined state (states of FIGS. 9 and 10), the ring-shaped protrusion 80a of the male member 80 pushes the tip contact portion 84b of the check member 84 outward in the radial direction.
Then, the locking recessed portion 84 a of the check member 84 is locked in the window portion 81.
The check member 84 is detached from the end edge of b and is popped out and detached by its elasticity in the direction perpendicular to the axis (the direction of the arrow in FIG. 19). Thereby, it can be confirmed that the male member 80 is coupled to the female member 82.

である。The conventional check member is a male member 80.
In a state before connecting the check member 84 to the female member 82, the check recess 84a is locked to the end edge of the window 81b of the housing 81 only by the elastic restoring force of the check member 84, so that the check member 84 tilts obliquely. Then, there is a problem that the housing 81 easily comes off. The present invention has been made in view of the above circumstances, and after connecting the male member and the female member, the check member is detached by an artificial operation so that the check member does not pop out due to its elasticity. It is an issue to be solved to provide a member.

ック部材94である。The check member is as shown in FIG. That is, a cylindrical male member 1 having an insertion end 1c provided with a ring-shaped protrusion 1a protruding in the centrifugal direction at a position separated from the distal end by a predetermined distance as shown in FIG. Insertion opening end 31 into which the portion 1c is inserted
d, and a female member 3 provided with a substantially cylindrical housing 31 having a pair of windows 35 arranged in the circumferential direction so as to penetrate in the radial direction and oppose each other at one axial end, and the inside of the housing 31. Has a pair of claw portions 43 that are inserted and held in the radial direction and that are elastically deformable in the radial direction and that are arranged at positions corresponding to the window portions 35. Each of the claw portions 43 extends axially inward from the insertion opening end 31d. Inclines radially inward as
An inclined inner surface 43a (FIG. 4) against which the ring-shaped protrusion 1a presses and slides when the male member 1 is inserted, and engages with the ring-shaped protrusion 1a when the male member 1 and the female member 3 are coupled. A connector having locking members 4 each having a locking end portion 43b (FIG. 4) that restricts the male member 1 from coming off, is externally held on the outer peripheral surface of the housing 31 in the direction perpendicular to the axis, and is elastically deformed. The C-shaped portion 94a capable of expanding the diameter and the locking end portions 43 of the claw portions 43 project integrally inward from both ends of the C-shaped portion 94a.
When the male member 1 is inserted into the housing 31 through the windows 35 at a position on the axially inner side of the housing 31 with respect to b, the male member 1 is not joined to the female member 3 and the male member 1 is A pair of locking projections 94b that lock with the circumferential end portion 35a of the window portion 35 in a state of being coupled to the female member 3 and one end side in the axial direction from substantially the circumferential center of the C-shaped portion 94a. The C-shaped portion 94 integrally extended to at least one of the other ends and held so as to stand upright in the direction perpendicular to the axis of the housing 31.
At least one tilt restricting portion 57 that restricts the tilting of a to at least one of the one end side and the other end side in the axial direction by contact with at least the outer peripheral surface of the housing 31.
And the tilt regulating portion 5 symmetrically with the C-shaped portion 94a.
7 is a check member 94 including a handle portion 94c extending in a direction perpendicular to the axis.

ら除去することができる。According to the check member 94, the pair of locking projections 94b at the tips of the C-shaped portions are in a state before the male member 1 is coupled to the female member 3 and the male member 1 is in the female member 3. When the male member 1 is coupled to the female member 3, the check member 94 does not pop out because it is engaged with the circumferential end portion 35a of the window portion 35 in the state of being coupled to. Then, in order to pull out the check member 94 in the state where the male member 1 is coupled to the female member 3, the handle portion 94c is pulled in the direction perpendicular to the axis to form a pair of locking protrusions 94b at the tip of the C-shaped portion. The check member 94 can be removed from the female member 3 by releasing the locked state with the circumferential end portion 35 a of the window portion 35.

たと同じ様な状態になる場合もある。By the way, when the check member 94 is pulled out from the housing 31 in the direction perpendicular to the axis after the male member 1 is completely inserted, the check member 94 is not necessarily pulled out in the same direction. For example, depending on the application location of the connector, the connector may be pulled out only in an oblique direction inclined to one end side or the other end side in the axial direction with respect to the direction perpendicular to the axis. In addition, there may be a case where the handle portion 94c hits another member and is pulled out in an oblique direction.

る。In such a case, before the insertion of the male member 1 is completed, that is, the connection between the male member 1 and the female member 3 is not properly completed, the pair of locking projections 94b of the check member 94 and the window. When the grip portion 94c is pulled in an oblique direction inclined to one end side or the other end side in the axial direction with respect to the direction perpendicular to the axis when the circumferential end portion 35a of the portion 35 is still locked, a C-shape is formed. A load is applied to the shape portion 94a in the direction opposite to the handle portion 94c. This load acts on the side wall of the window portion 35 or the claw portion 43 of the locking member 4. In this state, the tilt regulating member 57 is also loaded, and the tilt regulating member 57 elastically deforms. As a result, the pair of locking protrusions 94b of the check member 94 and the window 3
It is also conceivable that the check member 94 will be disengaged from the housing 31 if it is pulled strongly because the engagement with the circumferential end portion 35a of 5 becomes easy to disengage. In this way, although the connection between the male member 1 and the female member 3 is not completely completed,
If the check member 94 comes off from the housing 31, the function as the check member 94 will not be fulfilled.

離脱することのより一層の回避効果が生じる。In the check member of the connector having the above structure, the male member and the female member are not properly joined together, and the pair of locking projections of the check member and the circumferential end portion of the window portion are not connected to each other. Even when the handle portion is still locked, even if the handle portion is pulled in an oblique direction inclined to one end side or the other end side in the axial direction with respect to the axis-perpendicular direction, the load due to this is not applied to the C-shaped portion. That is, the load when the handle is pulled diagonally is
Absorbed at the bent portion, no load is applied to the C-shaped portion.
For this reason, the pair of locking projections of the check member are less likely to come off from the circumferential end of the window, and the check member does not separate from the housing even if pulled strongly, and the check member functions sufficiently. You can In the connector check member of the present invention, it is preferable that the tilt restricting portion has a reinforcing rib. As a result, the rigidity of the tilt restricting portion is increased, and the effect of further avoiding the check member tilting with respect to the housing and coming off is produced.

できない。Here, in the present embodiment, the distance between the straight line connecting the circumferential end portions 35a of each window portion 35 and the outer surface of the flat portion 31e of the housing 31 is determined by the distance between each first locking portion 52a,
A straight line connecting 52a and the flat portion 31 of the C-shaped portion 51
The above C should be slightly larger than the distance from the inner surface of e.
The dimensions of the character-shaped portion 51, the housing 31, and the like are set. With these configurations, the check member 5 is externally held by the housing 31, that is, each first locking portion 52a of each locking projection 52 of the check member 5 locks with the circumferential end 35a of the window 35. C of the check member 5 in the state
The character-shaped portion 51 is slightly elastically deformed, and this elastic force acts as a force that presses each first locking portion 52 a against each circumferential end portion 35 a of each window portion 35 in a substantially right angle direction. . As a result, as shown in FIG. 7, between the first locking portions 52a of the check member 5 and the inner surface of the C-shaped portion 51, the large diameter portion 31a of the housing 31 on the side where the check member 5 is mounted is attached.
The side wall of the large-diameter portion 31a in which the inner surface of the C-shaped portion 51 is in close contact with the pressure contact state is sandwiched in the direction perpendicular to the axis. As a result, the check member 5 is attached to the housing 3
1 is firmly and securely held, and the check member 5 is prevented from moving with respect to the housing 31.
Even if an attempt is made to pull out the check member 5 from the housing 31, it cannot be pulled out easily. (Operation) In the check member 5 of this connector, the male member 1
6, the small protrusion 57a on one end side of the tilt restricting portion 57 is fitted to the step portion of the large diameter portion 31a and the small diameter portion 31b of the housing 31, as shown in FIG. The check member 5 is externally held on the outer peripheral surface of the housing 31 from the direction perpendicular to the axis while the hook portion 57b is locked to the insertion opening end 31d. At this time, each locking projection 52 of the check member 5 is, as shown in FIG.
The claws 43 of the locking member 4 are inserted into the housing 31 through the windows 35 at positions on the axially inner side of the housing 31 with respect to the locking ends 43b of the claws 43, and the locking protrusions 52 1 locking portion 52a is a circumferential end portion 3 of each window portion 35.
