A protector 1 according to the present embodiment, as shown in FIG. 1, is arranged, for example, on the floor of a vehicle (not shown) and accommodates a wiring member W therein. The protector 1 is connected to a seat rail 2 arranged on the floor of the vehicle. The protector 1 includes, for example, an R protector arranged on the R side of the vehicle body and an L protector arranged on the L side of the vehicle body, but the L protector will be described as a representative.

The seat rail 2 is a guide rail for guiding the slide movement of the slide seat 3 along the slide direction (the X direction in the illustrated example). The seat rails 2 are connected to ends of the extending direction ends of the protector 1 that are formed so as to be folded back from one side to the other side, and are arranged close to the protector 1 along the extending direction. A pair of seat rails 2 are provided at intervals along the width direction. In the illustrated example, only one of the pair of seat rails 2 is shown, and the other seat rail 2 is omitted.

The slide seat 3, on which a passenger (not shown) of the vehicle sits, is installed so as to be slidable along the slide direction with respect to the floor of the vehicle. A slide seat 3 is supported by a pair of seat rails 2 .

The wiring member W is a wire or wire bundle (wire harness WH) for supplying electric power to electrical components (not shown) provided on the slide seat 3 (FIG. 4). At least a portion of the wiring member W is accommodated in the accommodation space portion 11 . For example, one end of the wiring material W is led out from the accommodation space 11 to the outside, is electrically connected to the electrical components of the slide seat 3 through the seat rail 2, and the other end is led out to the outside. and electrically connected to a vehicle power supply or the like (not shown). The wiring member W has a connector 21 which is configured to be able to be locked to the housing member 10 in the housed state of being housed in the housing space 11 and which is fitted with the mating connector 30 .

Connector 21 is, for example, a female connector. The mating connector 30 is, for example, a male connector (FIG. 3). The mating connector 30 is connected to one terminal in the extending direction of the wire harness WH. The other end of the wiring material W is led out to the outside through the connector 21 and the mating connector 30 which are in a fitted state. The connector 21 has a locking mechanism that locks onto the housing member 10 . A male side through lock 23 (locking portion) extending in the insertion direction is formed on one of a pair of opposing surfaces on the outer peripheral surface of the connector 21 (FIG. 5). The male side through lock 23 is provided on the outer surface of the housing member 10 facing the outer peripheral surface of the connector 21 in the locked state where the connector 21 is locked to the housing member 10, and extends in the direction opposite to the insertion direction. It is locked by the female side through lock 41 (lock receiving portion).

The protector 1 includes a storage space portion 11 that stores the wiring material W, a storage member 10 that forms at least a part of the storage space portion 11, and a cover 15 formed on the storage member 10 so as to be opened and closed. be done. The housing member 10 and the cover 15 are made of synthetic resin or the like, for example.

As shown in FIG. 2, the housing member 10 is composed of an upper case 13 and a lower case 14 in the protector 1. As shown in FIG. Upper case 13 is locked to lower case 14 by a locking structure. Upper case 13 and lower case 14 form at least a portion of housing space 11 when locked by the locking structure. The housing member 10 is formed by the housing member 10 and the closed cover 15 and has an insertion hole 12 into which the mating connector 30 is inserted (FIGS. 2 and 3). The housing space 11 communicates with the outside through the insertion hole 12 in the unlocked state in which the connector 21 is not locked to the housing member 10 . The insertion hole 12 is closed by the presence of the connector 21 when the cover 15 is closed and the connector 21 is locked to the housing member 10 . A female side through lock 41 is formed in the housing member 10 forming the inner peripheral surface of the insertion hole 12 . The female side through lock 41 is provided on the outer peripheral side of the connector 21 .

The cover 15 is a portion that is rotatably supported with respect to the housing member 10 between an open state that partially opens the housing space 11 and a closed state that partially closes the housing space 11 . be. The cover 15 is supported by the housing member 10 so as to be openable and closable with the hinge portion 15a as a pivot shaft. The hinge portion 15a is provided at one end in the extending direction of the housing member 10 and at one end in the width direction. The hinge portion 15a has a rotation axis in the extending direction of the housing member 10. As shown in FIG. The hinge portion 15 a is provided on the lower case 14 that constitutes the housing member 10 . The hinge portion 15a deforms as the cover 15 is opened and closed. The cover 15 is locked to the housing member 10 by a locking structure.

The cover 15 is formed at a position overlapping the connector 21 in the locked state when the cover 15 is closed and the connector 21 is locked to the housing member 10 when viewed from the insertion direction of the connector 21 . It has projections 16 (FIGS. 3 and 6). In addition, when the cover 15 is closed and the connector 21 is locked to the receiving member 10, the projection 16 is in the locked state when viewed from the connector 21 insertion direction. formed so as not to overlap the insertion opening of the Further, the projecting portion 16 is in an inserted state in which the trajectory (moving trajectory) ML of the tip in the projecting direction when the cover 15 is rotated is inserted into the insertion hole 12 and is not completely locked with the housing member 10. It overlaps the unlocked connector 21 (FIG. 8). The projecting portion 16 is, for example, a plate-shaped rib extending along the projecting direction from the closing surface 15b of the cover 15 (FIG. 6). The protrusion 16 constitutes a part of the inner peripheral surface of the insertion hole 12 and a part of the opening when the cover is closed. When the cover is closed, the protrusion 16 is formed to face the outer surface continuous with the outer surface formed with the female through lock 41 in the extending direction. The projecting portion 16 has a pressing surface 16a which is formed at the end in the projecting direction, contacts the connector 21 in the unlocked state, and presses the connector 21 in the insertion direction. The pressing surface 16a is, for example, an inclined surface that is formed in a direction that intersects the projecting direction and that is inclined from the tip of the projecting direction toward the connector 21 when the cover 15 is closed. When the cover 15 is in the closed state, the protrusion 16 is formed at a position overlapping the locking mechanism that locks the connector 21 and the housing member 10 when viewed from the insertion direction of the connector 21 . This locking mechanism is composed of, for example, the male side through lock 23 of the connector 21 and the female side through lock 41 of the receiving member 10 described above. It is preferable that the protrusion 16 is arranged on the cover 15 at a position farther away from the hinge portion 15a.

Next, a method for confirming whether or not the connector 21 is in the unlocked state with respect to the housing member 10 will be described with reference to FIG. In the assembly work of the protector 1, the operator inserts the connector 21 of the wiring material W partly accommodated in the accommodation space 11 into the insertion hole 12 while the cover 15 remains open. At this time, the connector 21 is inserted from above into the end of the concave portion of the housing member 10 that constitutes a part of the insertion hole 12 in the direction opposite to the insertion direction. Next, the operator pushes in the insertion direction until the connector 21 hits. At this time, the male side through lock 23 of the connector 21 is engaged with the female side through lock 41 of the housing member 10 while sliding in the insertion direction. Next, the operator closes the cover 15 to shift the cover 15 from the open state to the closed state. At this time, if the cover 15 is not sufficiently closed, the operator recognizes that the connector 21 is not locked with the housing member 10 and is in the unlocked state. That is, when the connector 21 is inserted into the insertion hole 12 and is in the unlocked state where the connector 21 is not completely locked with the housing member 10, even if the operator closes the cover 15, the projecting portion 16 is still in contact with the connector. 21 , it can be noticed that the connector 21 is not locked to the receiving member 10 . If the connector 21 is not properly locked, the projection 16 abuts on the connector 21 when the cover 15 of the protector 1 is closed, preventing the cover 15 from closing. can be verified.

Next, referring to FIG. 8, a description will be given of a method for shifting the connector 21 from the semi-locked state to the locked state by the protrusion 16. FIG. When the connector 21 is inserted into the insertion hole 12 and is in a semi-locked state in which the connector 21 is not completely locked with the housing member 10, when the operator closes the cover 15, the pressing surface 16a of the protrusion 16 is pushed. contacts the connector 21 . The pressing surface 16a is formed in a direction intersecting the projecting direction of the projecting portion 16, and is inclined toward the connector 21 side from the tip of the projecting direction when the cover 15 is closed. Therefore, when the operator presses the cover 15 in the closing direction, the connector 21 moves in the insertion direction while sliding on the pressing surface 16a, and the male through lock 23 of the connector 21 slides in the insertion direction. It is engaged with the female side through lock 41 of the housing member 10 . As a result, the operator can easily shift the semi-locked connector 21 to the locked state.

As described above, the protector 1 according to the present embodiment includes the storage space portion 11 that stores the wiring material W, the storage member 10 that forms at least a part of the storage space portion 11, and the storage member 10 that accommodates the storage member 10. A cover 15 is supported so as to be rotatable between an open state that partially opens the space 11 and a closed state that partially closes the housing space 11 . The wiring member W has a connector 21 which is configured to be able to be locked to the housing member 10 in the housed state of being housed in the housing space 11 and which is fitted with the mating connector 30 . The housing member 10 is formed by the housing member 10 and the closed cover 15 and has an insertion hole 12 into which the mating connector 30 is inserted. The accommodation space 11 communicates with the outside through the insertion hole 12 . The cover 15 is formed at a position overlapping the connector 21 in the locked state when the cover 15 is closed and the connector 21 is locked to the housing member 10 when viewed from the insertion direction of the connector 21 . It has a protrusion 16 . The projecting portion 16 is inserted into the insertion hole 12 so that the trajectory ML of the distal end in the projecting direction when the cover 15 is rotated is in an unlocked state in which the housing member 10 is not completely locked. 21 overlaps.

With the above configuration, when the connector 21 is inserted into the insertion hole 12 and is not locked with the housing member 10, even if the operator closes the cover 15, the projection 16 contacts the connector 21. , that the connector 21 is not locked to the receiving member 10 . If the connector 21 is not properly locked, when the cover 15 of the protector 1 is closed, the protrusion 16 comes into contact with the connector 21 and the cover 15 cannot be closed. can do.

In the protector 1 according to the present embodiment, the projecting portion 16 is formed at the end portion in the projecting direction, and has a pressing surface 16a that contacts the connector 21 in the unlocked state and presses the connector 21 in the insertion direction. have. As a result, for example, when the connector 21 is in a semi-locked state with respect to the housing member 10, when the pressing surface 16a of the protrusion 16 contacts the connector 21 when the cover 15 is closed, the closing force of the cover 15 is a pressing force. It becomes a force that pushes the connector 21 in the insertion direction via the surface 16a, and the semi-locked state can be changed to the locked state.

Further, in the protector 1 of the present embodiment, the projecting portion 16 is a plate-shaped rib extending from the cover 15 along the projecting direction. The pressing surface 16a is an inclined surface that is formed in a direction intersecting the projecting direction and that is inclined from the tip of the projecting direction toward the connector 21 side when the cover 15 is closed. By inclining the pressing surface 16a, when the force for closing the cover 15 is transmitted to the connector 21, it is easily converted into a pushing force in the insertion direction, so that the operator can close the cover 15 with less force. . As a result, the burden on the operator can be reduced.

In the protector 1 according to the present embodiment, the connector 21 has the male side through lock 23 on the outer peripheral side, and the housing member 10 faces the outer peripheral surface of the connector 21 in the inserted state in which the connector 21 is inserted into the insertion hole 12. It has a female side through lock 41 on the surface to be connected. The projecting portion 16 is formed at a position overlapping the male side through lock 23 and the female side through lock 41 when viewed from the insertion direction of the connector 21 when the cover 15 is in the closed state. As a result, when the projecting portion 16 pushes the connector 21, the vector of the pushing force does not escape from the direction in which the male side through lock 23 is locked to the female side through lock 41, so that the locking can be easily performed. becomes.

In addition, in the above-described embodiment, the hinge portion 15a has the rotation shaft in the extending direction of the housing member 10, but the present invention is not limited to this. The hinge portion 15a may have a rotation axis in a direction orthogonal to the extending direction. That is, even if the opening/closing direction of the cover 15 is changed from the width direction to the extension direction, the same effect as the present invention described above can be obtained.

In the above embodiment, the protrusion 16 is arranged at one of both ends of the opening of the insertion hole 12 when the cover 15 is closed, but it is not limited to this. For example, the protrusion 16 may be arranged at the other of both ends of the opening of the insertion hole 12 when the cover 15 is closed.
