Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wire press clamp used to hold an electric wire along a chassis or the like.

[0002]

[Prior Art]

 A press clamp has been conventionally used to extend an electric wire to a metal chassis of electric equipment. FIG. 7 shows an example thereof, which is composed of a body portion 31 and a lid portion which are hinge-coupled to each other at one end, and these body portion 31 and lid portion 32 are engaged with each other at an engaging portion 34 provided at the other end. Configure as possible. Further, a clip portion 33 is formed on the lower surface of the main body portion 31, and is fitted into a hole 21 provided in the chassis 20. The press clamp attaches the main body 31 to the chassis by inserting the clip portion 33 into the hole 21 of the chassis 20. Then, after the electric wire (flat cable) FC is placed on the main body portion 31, the cover portion 32 is covered and the engaging portion 34 is engaged with the main body portion 31, so that the electric wire FC is attached to the main body portion 31 and the lid portion. The electric wire can be held along the chassis 20 by being sandwiched between the electric wires.

[0003]

[Problems to be solved by the device]

 In such a conventional press clamp, since the clip portion 33 is used to attach to the chassis 20, the electric wire is held in a state in which the electric wire is separated from the chassis surface by the height dimension of the clip portion 33 and the main body portion 31. To be done. Therefore, there is a problem that the height dimension on the chassis surface becomes large. Further, the electric wire FC arranged along the chassis surface floats from the chassis surface at the place of the press clamp, which causes a problem that the electric wire is apt to become unstable. An object of the present invention is to provide a cable press clamp capable of holding an electric wire in a state of being juxtaposed to a chassis surface.

[0004]

Means for Solving the Problems The present invention provides a main body formed to have a required length, and the main body is provided in both ends of the main body, and the main body is inserted into holes formed in the chassis. An engaging portion that is attached to the main body and an elastically deformable pressing piece that protrudes from the main body toward the chassis, and the elastic force of the pressing piece keeps the electric wire between the main body and the chassis. Configure to have.

[0005]

[Action]

 Since the electric wire is held between the main body and the chassis, the electric wire can be held in a state in which the electric wire is in close contact with the chassis, stable holding is possible, and the height dimension can be reduced.

【Example】

 Next, the present invention will be described with reference to the drawings. 1 is a perspective view of a first embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof. In this press clamp, U-shaped engaging portions 2 are provided at both ends of a strip-shaped main body 1. The engaging portion 2 has a hook 3 on the outer surface and an operating portion 4 at the outer tip. Further, on both sides of the main body portion 1, pressing pieces 5 are provided so as to project in the left-right direction, with the tip thereof being inclined so as to be directed slightly downward. Here, the main body 1 is divided into two parts in the length direction, and the pressing pieces 5 are provided so as to project in different directions from the respective sides.

In the wire press clamp having this structure, as shown in FIG. 1, a pair of holes 21 corresponding to the engaging portions 2 are previously formed in the chassis 20. Then, as shown in FIG. 4 and FIG. 5, a wire (flat cable) FC is installed between these holes 21, and a wire press clamp is put on the wire FC so that each engaging portion 2 is holed. Insert into 21. Since the engaging portion 2 is U-shaped, the outer hook 3 is elastically returned after being inserted through the hole 21, and engages with the edge of the hole 21 on the rear surface side of the chassis 20 to secure the wire press clamp. It is fixed to the chassis 20. Then, in this state, the pair of pressing pieces 5 press the electric wire FC against the surface of the chassis 20 by the elastic force of the pressing piece 5 and hold the electric wire FC. As a result, the electric wire FC is held in close contact with the surface of the chassis 20. At this time, it is possible to hold electric wires having different thicknesses within the range of elastic deformation of the pressing piece 5, that is, within the range of the height of the main body 1.

In this held state, since there is no conventional clip, the overall height dimension can be reduced. Further, since the held electric wire is installed along the chassis, the noise current generated in the electric wire can be absorbed in the chassis, which is also effective for the EMI countermeasure which has become a problem in recent years. In this embodiment, the pressing pieces 5 are provided alternately on the left and right because the structure of the mold is simplified in consideration of the molding of the engaging portion 2, and this alone is sufficient. The pressing force can be obtained. However, if the mold is allowed to be complicated, if the left and right pressing pieces 5 are provided over the entire width of the main body 1, a more effective pressing force can be obtained and the electric wire holding effect can be enhanced. When the clamp is removed, the hook 3 can be released from the engagement with the edge of the hole 21 by bending the operation portion 2 of each engagement portion 2 inward.

FIG. 6 is a diagram showing a second embodiment of the present invention, in which the same parts as those in the first embodiment are designated by the same reference numerals. In this embodiment, one engaging portion 2A and the main body portion 1 are connected by a hinge 6, and normally this one engaging portion 2A is extended in a substantially linear direction with respect to the main body portion 1. is there. Then, in this state, the one engaging portion 2A is first fitted into one hole of the chassis, the electric wire is guided along the chassis, and then the hinge 6 is bent to connect the other engaging portion 2 to the chassis. By fitting the wire into the other hole, the electric wire can be held as in the first embodiment. In this way, if one engaging part 2A is fitted in one hole of the chassis at the outsourcing factory, the clamp will be supplied together with the chassis at the final assembly factory. Therefore, a separate clamp is prepared. Since it is not necessary to keep it in advance, it is possible to manage parts by improving assembly and reduce the number of assembly steps.

[0010]

[Effect of the device]

 As described above, according to the present invention, the both ends of the main body are provided with the engaging portions that are fitted into the holes provided in the chassis to attach the main body to the chassis, and the main body has the pressing pieces protruding toward the chassis. Since the wires are sandwiched between the chassis and the main body, the wires can be held in close contact with the chassis for stable holding and noise current can be reduced. This has the effect of reducing the height when held.
