For this type of cable clamp, for example, the technique disclosed in Patent Document 1 is already known. In this technique, one end of the semi-annular main body and the lid is connected by a hinge, a socket is provided at the other end of the main body, and a lock piece is provided at the other end of the lid. Yes. The socket of the main body includes a lock piece insertion hole and a bracket insertion hole. These both insertion holes are partitioned by a partition wall and open individually on both the upper and lower sides of the socket. In the lock piece insertion hole, the lock piece of the lid can be inserted from above the socket, and the lock piece is locked at a predetermined insertion position. In addition, a bracket protruding from the wiring target member (vehicle body) can be inserted into the bracket insertion hole from the lower side of the socket, and the bracket is locked at a predetermined insertion position.
When wiring a cable such as a wire harness to the vehicle body side, the outer periphery of the corrugated tube etc. through which the cable is inserted is sandwiched between the main body and the lid, and the lock piece is inserted into the lock piece insertion hole of the socket from above and locked. Put it in a state. Thereafter, the bracket is inserted into the bracket insertion hole of the socket from the lower side to be locked.
JP 2007-143309 A

In the technique disclosed in Patent Document 1, in the state where the outer periphery of the cable is gripped by the main body and the lid, the lock piece is inserted into the lock piece insertion hole of the socket from the upper side. The lock piece insertion hole remains open. Therefore, when the bracket is inserted into the bracket insertion hole of the socket from below, for example, one side of the bracket may be forcibly pushed into the opening of the lock piece insertion hole. Such a situation is likely to occur at a place where the cable wiring work is difficult, and as a result, the clamp is dropped from the vehicle body side, resulting in a wiring failure.
The reason why the lock piece insertion hole and the bracket insertion hole are opened on both the upper and lower sides of the socket is to remove the mold of each insertion hole during resin molding of the clamp.

  The present invention is intended to solve such a problem, and its purpose is to eliminate the room for the bracket to be pushed into a wrong place at the time of inserting the bracket into the socket, and always allow proper insertion. That is.

The present invention is for achieving the above object, and is configured as follows.
The first invention is a cable in which the outer periphery of a cable is gripped by a main body and a lid body whose one ends are connected by a hinge, and in this state, a cable that is attached to a bracket for mounting a clamp provided on a target member of cable wiring Among the other end portions of the main body and the lid body, a socket is provided on one side, and a lock piece is provided on the other side. The interior of the socket is divided into a first space in which a lock piece can be inserted and a second space in which a bracket can be inserted. The first space and the second space are configured such that the lock pieces and the brackets are inserted in the same direction, and the lock pieces and the brackets can be locked at the respective insertion positions.

  According to this configuration, since the lock piece is first inserted into the first space of the socket in the step of gripping the outer periphery of the cable by the main body and the lid, only the space of the second space is inserted on the subsequent insertion side of the socket. Not left. Therefore, when the bracket is inserted into the socket, the bracket cannot be inserted into the first space and is always properly inserted into the second space. As a result, even when it is difficult to route the cable by the clamp, the situation in which the bracket is forcibly pushed into the first space of the socket is solved.

  In a second aspect based on the first aspect, the first space and the second space of the socket communicate with each other. The first space is provided with an engaging claw that engages with a locking claw provided on the locking piece and locks the locking piece at the insertion position. The first space is configured to restrict the movement of the lock piece in the direction in which the engagement between the lock claw and the engagement claw is released by the bracket inserted into the second space.

  In this way, the movement of the lock piece inserted in the first space in the unlocking direction is restricted by the bracket that is subsequently inserted into the second space, so that this bracket is against the lock piece, so-called “wedge”. The reliability as a cable clamp is improved.

The best mode for carrying out the present invention will be described below with reference to the drawings.
The cable clamp shown in FIGS. 1 to 5 is intended for a wire harness (cable) wired in various places of the vehicle, and actually holds a protective corrugated tube 36 (FIG. 3) through which the wire harness is inserted. Of the form. This clamp is an integrally molded product made of synthetic resin.
As is apparent from FIGS. 1 and 2 showing the clamp before use, the clamp includes a main body 10 and a lid body 12 connected to each other by a thin hinge 14 having flexibility. ing. A socket 16 is provided at the other end of the main body 10, and a lock piece 20 is provided at the other end of the lid 12.

  The arc-shaped inner peripheral portions 10a and 12a in the main body 10 and the lid body 12 are portions that sandwich the outer peripheral surface of the corrugated tube 36. The inner peripheral portions 10a and 12a have two locking ribs 10b and 12b, respectively. Each column is provided. When the corrugated tube 36 is sandwiched between the main body 10 and the lid body 12, the locking ribs 10 b and 12 b are engaged with outer peripheral grooves (not shown) of the corrugated tube 36 so that the clamp and the corrugated tube 36 have a length. Prevent relative movement in the direction.

  The socket 16 of the main body 10 is configured in a hollow box shape opened on both upper and lower surfaces in FIGS. The inside of the socket 16 is divided into a first space 17 and a second space 18 by a boundary surface S shown virtually in FIG. In the first space 17, the lock piece 20 of the lid 12 can be inserted from the upper side of the socket 16. A clamp mounting bracket 30 to be described later can be inserted into the second space 18 from above the socket 16. That is, the insertion direction of the lock piece 20 and the bracket 30 with respect to the first space 17 and the second space 18 is the same direction.

  Engagement claws 17 a and 18 a are provided in the first space 17 and the second space 18, respectively. The engaging claw 17 a is located near the upper opening of the first space 17, and the engaging claw 18 a is located slightly below the lower middle of the second space 18. And since the insertion direction of the lock piece 20 and the bracket 30 with respect to the 1st space 17 and the 2nd space 18 is the same direction, the engaging surface in both the engaging claws 17a and 18a is facing down. The wall surface 18b of the second space 18 in which the engaging claws 18a are formed guides the insertion of the bracket 30 into the second space 18.

The lock piece 20 of the lid body 12 includes a lock claw 20 a on the inner side facing the inner peripheral portion 12 a of the lid body 12, and a plurality of reinforcing ribs 20 b are formed on the outer side of the lock piece 20. The lock claw 20 a of the lock piece 20 can be engaged with the engagement claw 17 a of the first space 17 in the socket 16.
The bracket 30 is a metal member fixed to a vehicle body or the like that is a target member for cable wiring. The bracket 30 is provided with an engagement hole 30 a that can engage with the engagement claw 18 a of the second space 18 in the socket 16.

Next, a procedure for wiring the wire harness (cable) will be described.
First, the main body 10 and the lid body 12 are closed by the hinge 14 as shown in FIGS. 3 and 4, and the corrugated tube 36 is sandwiched between the inner peripheral portions 10a and 12a. As a result, the lock piece 20 of the lid 12 is inserted into the first space 17 of the socket 16 in the main body 10 from above, and the lock claw 20a of the lock piece 20 and the engagement claw 17a of the first space 17 are engaged. Locked (FIG. 4). Therefore, the main body 10 and the lid body 12 are maintained in a state where the corrugated tube 36 is gripped. Further, in this gripping state, as described above, the locking ribs 10b and 12b of the inner peripheral portions 10a and 12a are engaged with the outer peripheral groove of the corrugated tube 36 to prevent relative displacement between the clamp and the corrugated tube 36. To do.

Next, the clamp holding the corrugated tube 36 is brought close to the vehicle body which is a wiring target member, and the bracket 30 fixed thereto is inserted into the second space 18 of the socket 16 and the lock piece 20 is inserted. Insert from above as in the direction. At this time, the space in one direction (the left-right direction in FIGS. 4 and 5) in the second space 18 is the wall surface 18 b and the back surface of each reinforcing rib 20 b of the lock piece 20 already inserted in the first space 17. It is fixed by.
That is, only the space of the second space 18 is left on the upper side (insertion side) of the socket 16, and even if wrong, a part of the bracket 30 is not forced into the first space 17. Accordingly, the bracket 30 is properly inserted into the second space 18 of the socket 16, and the engagement claw 18a of the second space 18 and the engagement hole 30a of the bracket 30 are engaged and locked (FIG. 4). Accordingly, the clamp is attached to the vehicle body, and the wire harness is held at the wiring position of the body.

  Further, by inserting the bracket 30 into the second space 18 of the socket 16, the lock piece 20 previously inserted into the first space 17 looks like “wedge” has been driven. Therefore, the movement of the lock piece 20 in the unlocking direction in which the engagement between the lock claw 20a and the engagement claw 17a is released is restricted, and the lock of the lock piece 20, that is, the reliability of the clamp by the main body 10 and the lid body 12 is controlled. Improves.

Although the best mode for carrying out the present invention has been described above with reference to the drawings, this embodiment can be easily changed or modified without departing from the spirit of the present invention.
For example, the cable gripped by the clamp is not limited to a wire harness, but also includes a single wire or a pipe for piping. Further, since the socket 16 of the main body 10 and the lock piece 20 of the lid body 12 in the clamp are in a relative relationship, the configuration may be such that the lock piece 20 is provided on the main body 10 and the socket 16 is provided on the lid body 12. Is possible.
