[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of the present invention. In the drawings, reference numerals 1 and 2 denote a pair of pipes (elongated) which are inserted through a through-hole 4 opened in a fixing member 3. These pipes 1 and 2 are fixed to the fixing member 3 by a resin clamp 5 described in detail below.

The resin clamp 5 is connected to each of the pipes 1, 2.
A branch 7 projects at a substantially right angle so as to intersect each of the pipes 1 and 2 with respect to a longitudinal middle part of the base 6 extending in the arrangement direction (vertical direction in FIG. 1). In the middle part, a concave part 8 into which one of the pipes 1 can be fitted and locked is provided with the base part 6.
A first gripper 9 is provided which is open toward one end of the base 6, and is provided at an intermediate portion between the other end of the base 6 and the base of the branch 7.
A second grip portion 11 is provided in which a concave portion 10 in which the other pipe 2 can be fitted and locked is opened toward the distal end side of the branch portion 7.

In the illustrated example, the first grip 9
Is intended for a relatively small-diameter pipe 1, so that the recess 8
A pedestal portion 12 for supporting the lower surface of the pipe 1 is provided at a bottom portion thereof, and a holding portion 13 for holding the side surface of the pipe 1 is provided on both sides of the concave portion 8. The portion is provided with a hook-shaped locking portion 14 which is expanded when fitting the pipe 1 to allow passage of the pipe 1 and holds the fitted pipe 1 so as not to be pulled out.

Further, since the second gripping portion 11 is intended for the pipe 2 having a diameter larger than that of the one pipe 1, the lower surface of the pipe 2 is supported by the bottom of the concave portion 10. In other configurations, the holding portion 15 and the locking portion 16 are provided as in the case of the first gripping portion 9 described above.

Further, in the resin clamp 5, the grips 9, 11 are provided at both ends in the longitudinal direction of the base 6.
Positioning means are provided so that the pipes 1 and 2 can be fitted and locked in the recesses 8 and 10 respectively, and can be fitted into the through-hole 4 at both ends in the longitudinal direction of the branch portion 7. There is provided a locking means which can be locked so as not to be pulled out.

The positioning means is constituted by arcuate reinforcing ribs 17, 18 protruding rearward at both end positions in the longitudinal direction of the base 6, respectively. The fixing member 3 is internally fitted partially along the edge of the through hole 4 at the vertical position.

The locking means includes a first locking claw 19 and a backing plate 20, and a second locking claw 21 and a backing plate 22 provided at both ends of the branch portion 7 in the longitudinal direction. It consists of.

The first locking claw 19 located on the base end side of the branch portion 7 is provided so as to project rearward so as to be able to lock the tip on the rear surface of the fixing member 3. First backing plate 2
Reference numeral 0 indicates that the front end of the first locking claw 19 abuts on the front surface of the fixing member 3 when the front end of the first locking claw 19 is locked on the rear surface of the fixing member 3.

On the other hand, the second locking claw 21 located on the distal end side of the branch portion 7 is protruded rearward and then folded forward to lock the distal end on the edge of the through hole 4. The second contact plate 22 is provided with the second locking claw 2.
The front end of the fixing member 3 comes into contact with the front surface of the fixing member 3 when the front end of the fixing member 3 is locked on the rear surface of the fixing member 3.

Here, the tip of the second locking claw 21 is
The second abutment plate 22 is formed so as not to hide the tip of the second locking claw 21 when being locked to the through hole 4 from the mounting side. .

The pair of pipes 1 and 2 arranged through the through-hole 4 opened in the fixing member 3 are connected to the fixing member 3.
When the resin clamp 5 is fixed to the first pipe 1, one of the pipes 1 is fitted and locked in the recess 8 of the first gripping section 9, and then the resin clamp 5 is rotated around the one of the pipes 1 to rotate the other pipe 2. To the second gripper 11
Is fitted and locked in the recess 10.

At this time, for example, if two grips are arranged in parallel in the same direction to fix a pair of pipes to the fixing member, the pipes must be fitted to each grip at the same time. Instead, both grips are pushed and expanded at the same time and interfere with each other, making it extremely difficult to fit a pipe to each grip, but in the present embodiment,
The first and second gripping parts 9, 11 are provided with the concave parts 8, 10 of each other.
Are arranged so as to be shifted at substantially right angles, so that even if the pipe 1 is fitted and locked in advance of the first grip 9, the pipe 2 There is no influence that hinders the fitting and locking, and the workability is extremely good.

Next, the resin clamp 5 is slid in the longitudinal direction of each of the pipes 1 and 2 and moved to the through hole 4 of the fixing member 3, and the first locking claw 19 is inserted into the through hole 4 to fix the tip. In addition to being locked to the rear surface of the member, positioning is performed by partially fitting the reinforcing ribs 17 and 18 partially to the upper and lower edges of the through hole 4, and then the second locking claw 21 is inserted into the through hole. 4 when it is bent inside and passes through the through-hole 4.
The second locking claw 21 is restored to its original position after passing through the through-hole 4, and the tip thereof is fixed to the rear surface of the fixing member 3 and the through-hole 4.
And the first and second abutment plates 20 and 22 are abutted against the front surface of the fixing member 3 and are locked to the through hole 4 so that the resin clamp 5 does not come off.

At this time, the locked state of the resin clamp 5 with respect to the through hole 4 can be confirmed by visually confirming the tip of the second locking claw 21 from the assembly side.

Therefore, according to the above-described embodiment, the pair of pipes 1 and 2 can be fixed to the fixing member 3 only by the integrally formed resin clamp 5 without the need for labor such as bolt fastening or the like. Since the number of components can be greatly reduced, the workability can be greatly improved, and the cost can be significantly reduced because only one component is required.

Further, since the locking state of the resin clamp 5 with respect to the through hole 4 can be visually recognized from the mounting side,
Poor assembly can be reliably prevented.

It should be noted that the resin clamp of the present invention is not limited to the above-described embodiment, and that the long member may be a harness or a cable other than the piping. The structure of the second gripping portion, the positioning means, and the locking means is not limited to the illustrated example, and it is needless to say that various changes can be made without departing from the gist of the present invention.
