Description

The present disclosure relates to clamps and wire harnesses.

2. Description of the Related Art Conventionally, when attaching a wire harness to an attachment target such as a vehicle body, a clamp may be used. Such clamps include, for example, arrowhead-shaped fasteners. In this clamp, the wire harness is attached to the attachment target by fitting the arrowhead-shaped fixing portion into the attachment hole of the attachment target using the elasticity of the fixing portion.

Further, for example, the clamp described in Patent Literature 1 has an attachment portion attached to a wire harness and a clip rotatably supported by the attachment portion. The clip has a shank and a pair of flexible locking arms extending in an inverted V shape from the tip of the shank. The tip of each flexible locking arm is provided with a locking stepped portion that is locked into a mounting hole of an object to be mounted. The mounting portion has an engaging portion around the shaft portion for varying the amount of deflection of each flexible locking arm. The engaging portion is a recess having an elliptical shape when viewed from the axial direction of the shaft portion. When the clip is rotated around the shaft, each locking stepped portion rotates together with the shaft while coming into contact with the inner peripheral surface of the engaging portion. The pair of flexible locking arms are elastically deformed so that the distance between their tips changes according to the position of each locking stepped portion relative to the engaging portion in the rotational direction of the shaft portion.

When attaching this clamp to an object to be attached, the position of each locking stepped portion with respect to the engaging portion in the rotational direction of the shaft portion is aligned with the position of the minor axis of the elliptical engaging portion. Then, the tips of the pair of flexible locking arms approach each other. After inserting the shaft and the pair of flexible locking arms into the mounting holes, the position of each locking step with respect to the engaging portion in the rotational direction of the shaft is adjusted to the length of the elliptical engaging portion. Align to position. Then, the tips of the pair of flexible locking arms move away from each other. The clip is locked in the mounting hole by causing the tip of each flexible locking arm to face the portion of the object to be mounted around the mounting hole. When the clamp is removed from the object to which it is attached, the position of each locking step with respect to the engaging portion in the rotational direction of the shaft portion is aligned with the position of the minor axis of the elliptical engaging portion.

By the way, in recent years, it has been desired to reuse the clamp.
A conventional clamp having an arrowhead-shaped fixing portion may be plastically deformed when the clamp is removed from an object to which it is attached. Therefore, it is unsuitable for reuse.

Moreover, the clamp described in Patent Literature 1 can be attached to and detached from an attachment target without plastically deforming the flexible locking arm. However, it is difficult to share the clamp when detachably attaching it to attachment holes of different sizes.

An object of the present disclosure is to provide a clamp that can be commonly attached to attachment holes of different sizes and that can be reused, and a wire harness that includes the clamp.

According to this configuration, it is possible to change the distance between the first engaging member and the second engaging member in the first direction. Therefore, it is possible to insert the first engaging member and the second engaging member into the mounting hole in a state where they are arranged at such intervals that they can be inserted into the mounting hole of the object to be mounted. After that, the distance between the first engaging member and the second engaging member is widened so that each of the first head portion and the second head portion is arranged at a position overlapping the portion of the mounting object surrounding the mounting hole. can be done. When each of the first head portion and the second head portion overlaps the portion around the mounting hole in the object to be mounted, each of the first head portion and the second head portion overlaps the portion around the mounting hole in the object to be mounted. can get caught. Therefore, the first and second engaging members are prevented from coming out of the mounting holes by the first and second head portions, that is, the clamp is attached to the attachment target. At this time, each of the first insertion portion and the second insertion portion is arranged to pass through the mounting hole, and at least a part of each of the first insertion portion and the second insertion portion is inside the mounting hole. placed. In this way, since the interval between the first engaging member and the second engaging member in the first direction can be changed within the range of the length of the rail, they can be commonly attached to attachment holes of different sizes. .

Further, in the clamp attached to the attachment target, the interval between the first engaging member and the second engaging member can be changed to an interval that allows the clamp to pass through the attachment hole. In this state, since the first engaging member and the second engaging member can be pulled out from the mounting hole, plastic deformation of the first engaging member and the second engaging member is suppressed, and the clamp can be removed from the mounting object. can be removed. Therefore, it is possible to reuse the clamp.

[2] When the first engaging member and the second engaging member are inserted into the mounting hole of the mounting object, the mounting object has a mounting hole on one of both sides of the mounting object in the penetrating direction of the mounting hole. Preferably, the first head portion and the second head portion are arranged, and the rail is arranged on the other side.

According to this configuration, both when the clamp is attached to the attachment target and when the clamp is removed from the attachment target, the first head portion and the second head portion, the distance between which is adjusted in the first direction, are inserted into the attachment hole. You can go to That is, it is not necessary to pass the rail through the mounting hole when attaching the clamp to the mounting target or when removing the clamp from the mounting target. Therefore, it is possible to prevent the rail from interfering with the inner peripheral surface of the mounting hole and the portion of the object to be mounted around the mounting hole when the clamp is attached and detached. Therefore, attachment and detachment of the clamp can be performed more easily. Furthermore, since it is possible to suppress the plastic deformation of the clamp when attaching and detaching the clamp, the clamp can be reused more easily.

[3] It is preferable that the second engaging member is slidable along the rail with respect to the rail.
According to this configuration, the distance between the first engaging member and the second engaging member in the first direction can be easily changed by sliding the second engaging member relative to the rail.

[4] The second engaging member has a first guide portion that sandwiches the rail from two directions along a third axis perpendicular to the first axis when viewed from a second direction along the second axis. is preferred.
According to this configuration, relative movement between the rail and the second engaging member in the direction along the third axis is suppressed by the first guide portion. Therefore, it is possible to suppress the second engaging member from rattling with respect to the rail. Moreover, it is possible to prevent the second engaging member from coming off the rail in the direction along the third axis.

[5] It is preferable that the second engaging member has a second guide portion that sandwiches the rail from two directions along the second axis when viewed from the first direction.
According to this configuration, relative movement between the rail and the second engaging member in the second direction is suppressed by the second guide portion. Therefore, it is possible to suppress the second engaging member from rattling with respect to the rail. Moreover, it is possible to prevent the second engaging member from coming off the rail in the direction along the second axis.

[6] The rail has a first retaining portion, and the second engaging member is disposed between the first engaging member and the first retaining portion in the first direction. and a second retaining portion, wherein the second retaining portion abuts against the first retaining portion from a direction from the first engaging member toward the second engaging member along the first axis. preferably accessible.

[7] Providing a stopper mounted on the first engaging member and the second engaging member and maintaining a constant distance between the first engaging member and the second engaging member in the first direction. is preferred.

According to this configuration, the stopper can suppress an unintended change in the distance between the first engaging member and the second engaging member in the first direction.
[8] The stopper has a plurality of mounting grooves aligned in the first direction, and each of the plurality of mounting grooves is perpendicular to the first axis when viewed from a second direction along the second axis. extending in a direction intersecting the first direction from one of both ends of the stopper in a third direction along a third axis, penetrating the stopper in the second direction, and forming one of the plurality of mounting grooves; Preferably, the first insertion portion is inserted into one mounting groove, and the second insertion portion is inserted into one mounting groove different from the mounting groove into which the first insertion portion is inserted.

According to this configuration, by inserting the first insertion portion into one of the plurality of mounting grooves and inserting the second insertion portion into another one of the mounting grooves, the stopper can be used in the first direction. The distance between the first engaging member and the second engaging member can be easily maintained constant.

According to this configuration, the width of the introduction portion in the first direction is narrower than the thickness of each of the first insertion portion and the second insertion portion. Therefore, it becomes difficult for the first insertion portion arranged in the slit hole to come out of the mounting groove through the introduction portion connected to the slit hole. Similarly, the second insertion portion arranged in the slit hole is difficult to come out of the mounting groove through the introduction portion connected to the slit hole. Therefore, it is possible to prevent the stopper from falling off from the first engaging member and the second engaging member. Also, the stopper has flexibility. Therefore, the operator can easily arrange each of the first insertion section and the second insertion section in the slit hole through the introduction section while bending the stopper. Further, the operator can push out each of the first insertion section and the second insertion section from the mounting groove through the introduction section through the slit hole while bending the stopper. That is, the operator can easily remove the stopper from the first engaging member and the second engaging member while bending the stopper.

[10] Preferably, the stopper has three or more mounting grooves.
According to this configuration, the first engagement in the first direction maintained by the stopper is determined by into which mounting groove the second inserting portion is inserted among the remaining mounting grooves excluding the mounting groove into which the first inserting portion is inserted. The interval between the joining member and the second engaging member can be changed. That is, the mounting groove into which the first insertion portion is inserted and the mounting groove into which the second insertion portion is inserted are arranged in the first direction according to the dimension of the mounting hole in the first direction and the second engagement member. It can be selected according to the distance from the member. Therefore, in a clamp commonly used for a plurality of types of mounting holes having different dimensions in the first direction with one type of stopper, the distance between the first engaging member and the second engaging member in the first direction can be kept constant. can be maintained.

[11] The fixed portion supports the rail so as not to move relative to the fixed portion, the first engaging member cannot move relative to the rail, and the second engaging member is , is preferably slidable along and relative to said rail.

According to this configuration, the positional relationship between the first engaging member and the rail in the first direction is fixed. Therefore, when the fixing portion is directly or indirectly fixed to the electric wire, the positions of the rail and the first engaging member with respect to the electric wire in the length direction of the electric wire are fixed. That is, relative movement of the first engaging member and the rail in the length direction of the electric wire is suppressed. Therefore, by using the first engaging member for positioning the wire harness with respect to the mounting hole in the length direction of the wire, it is possible to suppress positional deviation of the wire harness with respect to the attachment target in the length direction of the wire.

The wire harness of the present disclosure includes:
[12] A wire harness comprising: a wire member having at least one wire; and the above-described clamp in which the fixing portion is fixed to the wire member.
