Description

  The present invention relates to an insertion-type wiring molding that has an electromagnetic wave shielding and electrostatic shielding function for guiding and protecting an electric wire when wiring the electric wire on a floor surface, is excellent in strength, and is easy to assemble.

  As a conventional wiring duct for guiding and protecting an electric wire wired on the floor surface, as shown in the sectional view of FIG. 2A, a main body 20 having an engagement recess 23 and an engagement portion engaged with the engagement control recess 23 24, and includes a cover 21 that closes the opening of the main body 20, and is formed long in the front-rear direction so as to house and guide the wire 11 as shown in the perspective view of FIG. There are some (for example, refer to Patent Document 1).

JP 2000-92650 A

However, the wiring duct having such a shape is made of plastic and does not have an electromagnetic shielding function or an electrostatic shielding function, and is disposed on the floor to store electric wires (power lines, communication lines such as LAN cables). If a cart loaded with heavy objects passes over the wiring duct many times a day, the wiring duct will be crushed and the stored wires will be destroyed. The store, office wiring system, electronic equipment system was down.
In view of these points, an object of the present invention is to provide a plug-in wiring molding or an OA molding that has an electromagnetic shielding function and an electrostatic shielding function, is excellent in strength, and can be easily assembled.

  In order to achieve the above object, the plug-in type wiring molding of the present invention is made of a metal plate comprising a main body 1 and a cover 5, and the main body 1 is formed on the inner sides of both sides of the bottom plate 2 and the bottom plate in the width direction. It is bent so as to be in the range of 30 to 60 degrees, and has insertion side portions 3 and 3 that form insertion portions 4 and 4 between the bottom plate 2 and the cover 5 has a cross-sectional shape in the width direction. It is shaped into an arch shape, and both end portions 6 and 6 are inserted into the insertion portions 4 and 4 of the main body 1 so as to be slidable in the length direction, and integrated with the main body 1 so as to form a hollow storage path 7 inside. It is characterized by being made.

In the above, the metal plate is a steel plate.
Further, in the above, the insertion side portions 3 and 3 of the main body 1 are bent so as to have a shape matching the cross-sectional shape of the cover 5 in the width direction.
Furthermore, the dimensions are characterized in that the width of the bottom surface is about 100 mm, the height is about 20 mm, and the length is about 500 mm or about 700 mm.
Further, the wiring molding is an OA molding.

  According to the present invention, in view of the shape and material of the molding, even if a cart loaded with heavy objects passes over the molding, the cover does not come off from the main body, and therefore the molding is not crushed. It is possible to safely protect the electric wires that are being used from heavy objects.

Embodiments of the present invention will be described based on examples with reference to the drawings.
FIG. 1 is a cross-sectional view (a) and a perspective view (b) of an insertion-type wiring molding according to the present invention.
Reference numeral 1 denotes a main body, which includes a bottom plate 2 and insertion side portions 3 and 3 on both sides in the width direction. The insertion side portions 3 and 3 are bent inward and inserted between the bottom plate 2 and the insertion portions 4 and 4. Is forming.
Reference numeral 5 denotes a cover whose cross-sectional shape in the width direction is shaped like an arch, and both end portions 6 and 6 thereof are inserted into the insertion portions 4 and 4 of the main body 1 so as to be slidable in the length direction. The storage path 7 of the electric wire 8 is formed between the two.
The bottom plate 2 of the main body 1 is provided with an adhesive coated with release paper for bonding to the floor surface, and can be bonded and fixed by peeling the release paper and pressing it against the floor surface.

The insertion side 3 of the main body 1 is not simply bent, but is matched to the cross-sectional shape in the width direction of the cover 4 so that the inner peripheral surface of the insertion side 3 is in surface contact with the outer peripheral surface of the end 6 of the cover 5. It is preferable that it is formed so as to have an arch shape. Thereby, the penetration | invasion of the dust to the inside of the storage path 7 can be decreased.
The main body 1 and the cover 5 are formed of a thin metal plate such as a steel plate in consideration of strength, but are not limited to a steel plate.

  When the cover 5 is attached to the main body 1, with one end 6 of the cover 5 inserted into one insertion part 4 of the main body 1 with the electric wire 8 stored, the cover 5 is then bent slightly inward. In the state, the other end 6 is inserted into the other insertion portion 4 of the main body 1, or the cover 5 is inserted into the insertion portion 4 of the main body 1 from the length direction of the main body 1. , 4 and the cover 5 can be easily attached to the main body 1 and integrated.

  In a state where the cover 5 is inserted into the main body 1, both end portions 6, 6 of the cover 5 are not inserted into the insertion portion 4 of the main body 1 so that a cart loaded with heavy objects passes over the molding. , 4, the folding angle of the insertion side portions 3, 3 should be in the range of about 30 degrees to 60 degrees, and the folding length needs to take this point into consideration, and how much of these It is necessary to select appropriately according to the size of the molding determined in relation to the size of the electric wire to be stored.

  The dimensions of the mall can be appropriately selected according to the dimensions of the electric wires to be stored. For example, in the case of a LAN cable, the width of the bottom surface is about 100 mm, the height is about 20 mm, and the length is long. It may be about 500 mm or about 700 mm.

  Since the shape of the molding is as described above, and the material of the molding is a metal plate such as a steel plate, the cover 5 can be removed from the main body 1 even if a cart loaded with heavy objects passes over the molding. (Withstand load of 100 kg), and therefore, the molding is not crushed, so that the stored electric wire is safely protected from heavy objects passing over it.

  In addition, since the molding is made of a metal plate, the molding itself has an electromagnetic shielding effect, which prevents the electric wires inside the molding from being affected by electromagnetic waves generated from electronic devices, electric wires, etc. outside the molding. Conversely, electronic devices, electric wires, etc. outside the mall can prevent the influence (failure) caused by electromagnetic waves generated from the electric wires inside the mall.

  Similarly, the mall itself has an electrostatic shielding effect, and it is possible to prevent a failure caused by noise that occurs due to the discharge of static electricity inside and outside the mall.

In addition, since the molding is formed of a metal plate, it has an electromagnetic shielding effect and an electrostatic shielding effect, thereby preventing mutual influence (failure) between the electric wires and electronic devices inside and outside the molding.
Furthermore, it is easy to attach the cover to the main body, and even when a plurality of electric wires are accommodated, the electric wires can be easily attached without being bitten.
