[Industrial applications]

 The present invention relates to an edging saddle provided to protect a coating of an electric wire when the electric wire is inserted into a notch or an opening provided in a panel, a chassis or the like.

[0002]

[Prior Art]

 When inserting a wire into a notch or opening provided in a metal panel or chassis of electrical equipment, if the edge of the notch or opening is exposed as it is, the wire will not be The coating is damaged and the wire is less reliable. In addition, the internal conductive wires are exposed and come into contact with the panel, etc., resulting in an accident such as a short circuit or an electric leakage. For this reason, conventionally, a part called an edging saddle has been provided to cover the edge of the notch.

FIG. 7 shows an example of a conventional edging saddle. A body portion 31 is formed as a U-shaped frame made of synthetic resin or the like so as to correspond to the rectangular notch 21 provided in the chassis 20. It is attached so that the edge of the notch 21 is sandwiched by a plurality of protrusions 32 protruding on both sides. In addition, a pair of clamp pieces 33 are opposed to the inside from both sides of the opening. In this way, the electric wire C inserted into the edging saddle is covered with the edging saddle at the edge of the notch 21 of the chassis 20, so that the electric wire C is not directly contacted with the notched edge. Damage to the wire coating is prevented. Further, the inserted electric wire is suppressed by the clamp piece 33 from coming off the edging saddle.

[0004]

[Problems to be solved by the device]

 In such a conventional edging saddle, the edges of the notch 21 are sandwiched by the protrusions 32 provided on both side surfaces of the edging saddle. Therefore, when the distance between the protrusions 32 and the plate thickness of the chassis 20 do not match, it is suitable. I can't wear it. For this reason, it is necessary to prepare various edging saddles having different projection intervals in order to be able to deal with various chassis having different plate thicknesses, which makes manufacturing and management troublesome. .

Further, although 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 space in consideration of inserting the electric wires and have an elastic force. Since the cable is designed to be low, it is easy to insert the wire, but on the contrary, there is a problem that the wire is easily detached. Also, if the space is narrowed and the wires are hard to come off, it becomes difficult to insert a thick wire or wire bundle. Further, conventionally, since the edging saddle is fitted so as to be inserted from the opening side of the notch, the edging saddle cannot be attached to the opening hole whose periphery is not open. An object of the present invention is to provide an edging saddle that can be applied to panels and chassis having different plate thicknesses and that prevents the wires from coming off.

[0006]

[Means for Solving the Problems]

 According to the present invention, a frame-shaped main body part that is fitted into a notch or an opening provided in a panel, a chassis, or the like, and a part of the main body part is opened, and the opening end of the main body part is hinged to form the aforementioned opening. It includes a lid that can be closed, a flange that is provided on one surface of the main body, and an elastically deformable engagement piece that is provided on the other surface of the main body that faces the flange. The flange and the edge of the opening are sandwiched between the flange and the flange.

[0007]

[Action]

 Due to the elastic deformation of the engaging piece, it is possible to absorb the difference in the plate thickness of the panel, the chassis, etc., which is sandwiched between the engaging piece and the flange, and to mount the panel to any plate thickness. In addition, the lid allows the wires to be easily inserted by fully opening the main body, and the lid prevents the wires from falling off.

[0008]

EXAMPLES 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, and FIG. 3 is a plan view. The edging saddle has a main body 1 formed as a U-shaped frame having a size that can be fitted into a rectangular notch 21 formed in a panel or a chassis 20 and is formed of a resin having some elasticity. The flange 2 is integrally formed at the edge portion of and the cross-sectional shape is formed in an L shape. Further, the widths of the flanges 2a on both sides are increased, while the tongue-shaped engagement piece 3 having a tip projecting in both directions is provided on the other edge of the both sides so as to face the flange 2a. ing . The outer side of the tip of the engaging piece 3 is formed as a tapered surface, and a plurality of engaging grooves 4 extending in the vertical direction are formed in a stepwise arrangement on the tapered surface.

A lid 6 is supported by a hinge 6 on one end of one side piece of the main body 1. A U-shaped lock piece 7 is formed at the tip of the lid 5. The lock piece 7 has a hook 8 formed on the tip side and a release portion 9 for releasing the lock. On the other hand, a lock hole 10 into which the lock piece 7 is fitted is opened at the end of the other side piece of the main body portion 1, and when the lock piece 7 is fitted, the hook 8 is inserted into the lock hole 10. It engages with one edge and makes the edging saddle endless to form a rectangular frame. The lock piece 7 can be disengaged from the lock hole 10 by operating the release portion 9 to narrow the U-shaped width dimension.

According to this structure, as shown in FIG. 5, the body portion 1 of the edging saddle is fitted from the opening side of the notch 21 provided in the chassis 20, and one surface thereof is brought into contact with the flanges 2 and 2a. . At this time, as shown in a part in FIG. 4, the engaging piece 3 is elastically deformed inward, and the edge of the notch 21 is inserted. Then, after being inserted, it elastically returns, and the engagement groove 4 provided in the tapered surface engages with the edge portion of the notch 21. As a result, the edge portion of the notch 21 is sandwiched between the flange 2a and the engaging piece 3, whereby the edging saddle is held in the notch 21. At this time, even if the plate thickness of the chassis 20 is different as shown by the phantom line in the figure, any of the plurality of engaging grooves 4 provided in the engaging piece 3 is engaged with the notch edge portion. The difference in plate thickness can be absorbed by the elastic deformation of the engaging piece 3, and the invention can be applied to any plate thickness.

Next, the electric wire (cable) C is inserted into the edging saddle. At this time, by fully opening the lid portion 5, a thick electric wire or electric wire bundle can be easily inserted. After that, the lid 5 is bent using the hinge 6, and the lock piece 7 provided on the lid 5 is fitted into the lock hole 10 of the main body 1. As a result, the edging saddle has a closed frame shape, and the inserted electric wire C is reliably prevented from falling off. If the lock piece 7 is removed from the lock hole 10, it is possible to easily remove the inserted electric wire or newly insert the electric wire. Furthermore, if the engaging piece 3 is elastically deformed inward and the engagement with the edge of the notch 21 is released, the work of removing the edging saddle from the notch can be easily performed.

Further, this edging saddle can be applied to the opening window 22 of the chassis 20 whose periphery is closed as shown in FIG. That is, the lock piece 7 of the lid 5 is fitted into the lock hole 10 to form a frame shape, and then the main body 1 of the edging saddle is pushed in from one side of the opening window 22, so that the engagement piece 3 is inwardly moved. After being elastically deformed, the main body 1 and the lid 5 are fitted into the opening window 22. Then, the engagement piece 3 elastically returns to the outside and the engagement groove 4 engages with the edge portion of the opening window 22, so that the edge portion of the opening window 22 is sandwiched between the flanges 2 and 2a and the engagement piece 3. However, the edging saddle can be attached to the chassis 20. Needless to say, the edging saddle of the present invention can be configured in various shapes such as a circle, an ellipse, a triangle, and a polygon. Further, the window portion 11 provided on the flange portion 2a is an escape hole for molding the engaging piece 3 when the edging saddle is resin-molded, and is not particularly required functionally.

[0013]

[Effect of the device]

 As described above, the present invention is configured so that the flange of the main body and the elastically deformable engagement piece provided facing the flange sandwich the notch or the edge of the opening. Therefore, it can be mounted on panels or chassis having different plate thicknesses. Further, since the lid portion that can open and close the opening provided in the main body portion is provided, it is possible to easily insert the electric wire and to reliably prevent the electric wire from falling off. Further, the present invention can be applied not only to notches such as a panel and a chassis but also to an opening whose periphery is closed, and has an effect of expanding the application range.
