BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edging saddle provided for protecting a coating of an electric wire when the electric wire is inserted into a notch or an opening provided in a panel or a chassis.

[0002]

2. Description of the Related Art When an electric wire is inserted through a notch or an opening provided in a metal panel or a chassis of an electric device, if the edge of the notch or the opening is exposed as it is, the electric wire is rubbed by the edge. Sometimes the sheath of the wire is damaged, reducing the reliability of the wire. In addition, the inner conductive wires are exposed and come into contact with the panel or the like, and an accident such as a short circuit or a short circuit occurs. For this reason, a component called an edging saddle has conventionally been provided to cover the edge of the notch.

FIG. 7 shows an example of a conventional edging saddle, in which a main body 31 is formed as a U-shaped frame made of synthetic resin or the like so as to correspond to a rectangular notch 21 provided in a chassis 20. A plurality of protrusions 3 protruding on both sides
2 is attached so as to sandwich the edge of the notch 21. Also, a pair of clamp pieces 3 are provided from both sides of the opening.
3 faces slightly inward. With this configuration, the wire C inserted into the edging saddle is not directly contacted with the notch edge because the edge of the notch 21 of the chassis 20 is covered by the edging saddle. The coating of the electric wire is prevented from being damaged.
Further, the inserted electric wire is prevented from being detached from the edging saddle by the clamp piece 33.

[0004]

In such a conventional edging saddle, the edges of the notches 21 are sandwiched between the projections 32 provided on both side surfaces of the saddle. If the thickness does not match, it cannot be mounted properly. Therefore, in order to be able to cope with various chassis and the like having different plate thicknesses, it is necessary to prepare various edging saddles having different projection spacing dimensions, which makes the production and management troublesome.

The electric wires inserted through the edging saddle are prevented from coming off by the clamp pieces 33. These clamp pieces 33 are provided with a required interval in consideration of insertion of the electric wires, and have an elastic force. Since the design is low, the insertion of the electric wire is easy, but on the contrary, there is a problem that the electric wire is easily detached. Also, if the distance is reduced to make it difficult for the wires to come off, it becomes difficult to insert a thick wire or wire bundle. Furthermore, since the edging saddle is conventionally fitted so as to be inserted from the opening side of the notch, it is impossible to attach the edging saddle to an opening hole whose periphery is not opened. SUMMARY OF THE INVENTION An object of the present invention is to provide an edging saddle that can accommodate panels, chassis, and the like having different thicknesses and that prevents an electric wire from coming off.
