Description

  The present invention relates to a cable clamp that is used to hold, for example, a wire harness (cable) wired inside a vehicle door at a predetermined position in the length direction thereof.

This type of clamp has a bowl shape having a receiving portion that can receive and support a part of a continuous wire harness, and a rib for preventing slippage is formed on the wall surface in the receiving portion. ing. Then, when setting a wire harness in a receiving part, a rib is bitten in the outer periphery using the compression deformation of a wire harness. This prevents the wire harness from moving in the length direction relative to the clamp.
Patent Document 1 discloses a technique related to a clamp for preventing a corrugated tube (cable) from shifting using a rib.
JP 2002-78164 A

  In the above technique, when the wire harness is set in the receiving part of the clamp, it is necessary to forcibly push the wire harness between the ribs, and the operation load for setting the wire harness increases. Moreover, the outer diameter of the wire harness which can be pushed in between ribs is limited, and a clamp having a size corresponding to the diameter of the wire harness must be prepared.

  The present invention is intended to solve such a problem, and its purpose is to set a cable even though the cable such as a wire harness can be prevented from shifting in the length direction. It is possible to reduce the operating load and absorb the difference in the outer diameter of the cable.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is a cable clamp for holding a cable at a predetermined location, and includes a clamp body having a cable receiving portion capable of receiving and supporting a part of a continuous cable. And a locking piece projecting from the wall surface in the cable receiving portion of the clamp body. This locking piece can be bent by elasticity in the length direction of the cable with respect to the clamp body, and it will bite into the outer periphery of the cable to receive the pulling force against the pulling force acting on the cable. It is configured.

  This will not only prevent the cable after it is set in the cable receiving part of the clamp body from moving in the length direction due to the pulling force, but also when setting the cable in the cable receiving part. The load is small and the difference in the outer diameter of the cable can be absorbed.

The invention according to claim 2 is the cable clamp according to claim 1, wherein the locking pieces are respectively provided at two locations along the length direction of the cable. The directions for receiving the pulling force acting on the cable are set in opposite directions.
As a result, the pulling force acting on the cable can be received regardless of the direction.

The invention according to claim 3 is the cable clamp according to claim 1 or 2, wherein the locking piece projects from the wall surface located on both sides of the cable in the cable receiving portion of the clamp body. Paired.
As a result, the function of receiving the tensile force acting on the cable is enhanced.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a use state of the clamp. FIG. 2 is a left side view of FIG. FIG. 3 is a plan view of FIG. The clamp body 10 shown in these drawings is an integrally molded product made of resin, and has a bowl shape as a whole. In other words, the clamp body 10 includes two vertical walls 10a and 10b that are opposed to each other at a predetermined interval, and a cable receiving unit in which an upper surface and both side surfaces are opened between the vertical walls 10a and 10b. It is part 12.

  The clamp body 10 is, for example, for holding the wire harness 22 on the back surface (door panel side surface) of the door trim 20 (FIGS. 2 and 3) in the vehicle door, and one vertical wall 10a is resin on the back surface of the door trim 20. Bonded by means such as welding. The other vertical wall 10 b in this state is located in a state of protruding from the back surface of the door trim 20. Therefore, by inserting the wire harness 22 into the cable receiving portion 12 from the upper side, a part of the wire harness 22 is held on the door trim 20 side.

  Therefore, by providing a plurality of clamp bodies 10 at necessary locations on the back surface of the door trim 20 and holding the wire harness 22 with each of the clamp bodies 10, the wire harness 22 is wired along the back surface of the door trim 20. The In addition, in order to make it easy to set the wire harness 22 to the cable receiving portion 12, the upper end edge of the vertical wall 10 b is bent in a direction to widen the open area of the cable receiving portion 12. The wire harness 22 is an example of a cable, and the cable includes a single wire or a tube.

  In the cable receiving portion 12 of the clamp body 10, two pairs of locking pieces 14 and 15 and a pressing piece 18 are provided. Of the two sets of locking pieces 14 and 15, the pair of locking pieces 14 positioned near the left end of the cable receiving portion 12 in FIG. 3 are integrally integrated obliquely leftward from the inner surfaces of the vertical walls 10 a and 10 b. It is overhanging. Both the locking pieces 14 can be easily bent leftward from their free state due to their elasticity. Further, in FIG. 3, the pair of locking pieces 15 positioned near the right end of the cable receiving portion 12 individually project integrally from the inner surfaces of the vertical walls 10a and 10b obliquely to the right. Both the locking pieces 15 can be easily bent rightward from the free state due to their elasticity.

  The two pairs of locking pieces 14 and 15 that form a pair in this way are provided at two locations along the length direction of the wire harness 22 in the cable receiving portion 12. In addition, the front end side upper edge of each locking piece 14 and 15 is the slopes 14a and 15a, respectively. The holding piece 18 is located approximately in the middle of the two sets of locking pieces 14 and 15 and projects integrally downward from the inner surface of the vertical wall 10b. The pressing piece 18 can be bent in the vertical direction by its elasticity.

  Next, a procedure for holding the wire harness 22 on the clamp body 10 will be described. A wire harness 22 is inserted into the cable receiving portion 12 of the clamp body 10 from above. At this time, the holding piece 18 is bent upward, or the wire harness 22 is allowed to pass while being pressed downward. On the other hand, the two sets of locking pieces 14 and 15 that form a pair with each other are bent by the wire harness 22. That is, the pair of locking pieces 14 positioned near the left end of the cable receiving portion 12 are individually bent leftward by the wire harness 22 entering between them. Further, the pair of locking pieces 15 positioned near the right end of the cable receiving portion 12 are individually bent in the right direction when the wire harness 22 enters between them. The wire harness 22 is guided by the inclined surfaces 14a and 15a of the locking pieces 14 and 15, and smoothly enters between them.

  As described above, the wire harness 22 is gripped at two positions in the length direction by the two sets of locking pieces 14 and 15 and pressed against the bottom surface of the cable receiving portion 12 by one pressing piece 18. It becomes. Thereby, a part of the length direction in the wire harness 22 is held in a state of being set in the clamp body 10. Of the two sets of locking pieces 14, 15, the pair of locking pieces 14 bite into the outer periphery of the wire harness 22 when a pulling force in the right direction in FIG. 3 acts on the wire harness 22. Receive the pulling force. In contrast, when a pulling force in the left direction is applied to the wire harness 22, the pair of locking pieces 15 bite into the outer periphery of the wire harness 22 and receive the pulling force.

  As described above, the two pairs of locking pieces 14 and 15 that form a pair are set in opposite directions to receive the tensile force acting on the wire harness 22. Therefore, the movement of the wire harness 22 relative to the clamp body 10 can be suppressed by receiving the respective forces against the pulling force in either the left or right direction. Moreover, of the two sets of locking pieces 14, 15, the pair of locking pieces 14 is easily bent leftward by the wire harness 22, and the pair of locking pieces 15 is easily bent rightward. For this reason, the operation load when setting the wire harness 22 to the cable receiving part 12 is small, workability is improved, and the wire harness 22 is hardly damaged. Moreover, the difference in the outer diameter of the wire harness 22 can be absorbed by the bending of the locking pieces 14 and 15, and one type of clamp can cope with various types of wire harnesses having different outer diameters.

  When the pulling force acting on the wire harness 22 can be considered only in one direction, one set of the two sets of locking pieces 14 and 15 may be eliminated. For example, when only the pulling force in the right direction of FIG. 3 acts on the wire harness 22, only the locking piece 14 that receives the pulling force remains, and the other locking piece 15 can be eliminated. Further, each of the two sets of locking pieces 14 and 15 can be changed from two to one. For example, the locking pieces 14 and 15 are provided only on one vertical wall 10a in the cable receiving portion 12, and the locking pieces 14 and 15 on the other vertical wall 10b are eliminated. Even in this case, the movement of the wire harness 22 can be sufficiently suppressed depending on the degree of the pulling force acting on the wire harness 22.
