DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective cover fitting for covering an outer periphery of a wire with a wire protection cover.

[0002]

2. Description of the Related Art When an electric, telephone, cable broadcast, CATV, or the like is drawn into a user's house, the service line may approach or come into contact with a building or a power line. Therefore, when there is a risk that the service line may approach or come into contact with a building or a power line, the electric wire must be protected by wrapping a protective material around the electric wire.

[0003] When a wire is covered with a wire protection cover, which is a protective material, the wire protection cover is pushed and opened by hand and applied to the wire, and the wire protection cover is wound and covered so as to wrap the wire.

[0004]

However, the electric wire protection cover is formed by rolling a ribbon-shaped rubber plate into a straw shape. Because of the return, it takes a great deal of labor and time to cover the lead wire having a length of several meters with the wire protection cover over the entire length, and it has been particularly difficult to work at a high place.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a protective cover mounting device capable of easily covering a wire with a wire protective cover in a short time.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a protective cover mounting device for covering an outer periphery of an electric wire with an electric wire protection cover. A substantially heart-shaped mounting body having an insertion hole formed therein, an arc-shaped gripping surface portion on the outer peripheral side and a guide groove having a V-shaped cross section on the inner peripheral side, and a tip of the guide groove of the mounting body. And a push-opening piece that is inserted into the wire protection cover in advance.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0008] As shown in FIG.
Is a substantially heart shape in which an insertion hole 3 having an arc-shaped cross section through which the wire protection cover 2 is inserted is formed in the longitudinal direction, a gripping surface portion 4 having an arc shape on the outer circumference side, and a guide groove 5 having a V-shaped cross section on the inner circumference side. And a push-opening piece 7 inserted into the wire protection cover 2 at the tip of the guide groove 5 of the fixture body 6.
Are integrally formed, and are made of plastic.

As shown in FIGS. 3, 5 and 6, the push-opening piece 7 is a protrusion having a V-shaped cross section extending from the guide groove 5 in the longitudinal direction. The push-opening piece 7 is tapered so as to gradually spread from the tip to the root, and guides the pushed-in wire protection cover 2 into the insertion hole 3 while gradually opening.

The guide groove 5 is for guiding the fixture main body 6 so as to move along the electric wire 8, and is located above the fixture main body 6. As shown in FIGS. 2 and 4, the bottom 9 of the guide groove 5 is formed with a curved surface having a diameter enough to accommodate the electric wire 8, and when the electric wire 8 in the groove is pressed from above by a finger, the bottom of the groove is formed. 9 is provided with a gap that allows the electric wire 8 to pass therethrough. The surface of the bottom 9 of the guide groove 5 is formed smoothly so that the electric wire 8 can be smoothly guided.

The grip surface portion 4 is a portion for gripping at the time of work, and is located at a lower portion of the fixture body 6.

As shown in FIGS. 2 and 4, the insertion hole 3 is a hole formed in an arc shape with the lower part on the outer peripheral side.
This is for guiding the electric wire protection cover 2 to the electric wire 8 extending from the rear end in a continuously open state. The upper inner surface 10 of the insertion hole 3 has a diameter larger than the inner diameter of the arc formed by the open wire protection cover 2 so that the upper inner surface 10 contacts only the side edge of the wire protection cover 2 opened by the push-piece 7. The lower inner surface 11 of the insertion hole 3 is
So that the center of the outer periphery of the electric wire protection cover 2 is pushed upward so as to keep it open.

The upper inner surface 10 and the lower inner surface 11 of the insertion hole 3 are formed smoothly so as to guide the wire protection cover 2 smoothly.

Next, the operation will be described.

When the electric wire protection cover 2 is attached to the electric wire 8, one end of the electric wire protection cover 2 is inserted into the insertion hole 3 of the protection cover fixture 1 as shown in FIG.

At this time, the tip of the push-opening piece 7 of the protective cover attachment 1 is inserted from one end of the electric wire protection cover 2 into the electric wire protection cover 2, and the electric wires are placed such that both edges of the electric wire protection cover 2 face upward. Push open the protective cover 2. Then, the push-opening piece 7 is pushed into the wire protection cover 2 as it is, and one end of the wire protection cover 2 is inserted into the insertion hole 3. When pushing the push-piece 7 into the wire protection cover 2, one end of the wire protection cover 2 is further expanded at the base of the push-piece 7 and then spread along the upper edge of the insertion hole 3. As a result, the wire protection cover 2 can be easily and quickly inserted into the insertion hole 3.

Next, as shown in FIG. 1, one end of the wire protection cover 2 which is extended from the rear end of the insertion hole 3 and is in a half-open state is wound around the end of the wire 8 to be covered, and guided by the wire 8. The grooves 5 are aligned so that the electric wires 8 fit into the guide grooves 5. At this time, the grip surface 4 is gripped with the palm of the
Can be easily stabilized by pressing the wire against the electric wire 8, and the operation can be easily performed.

Then, one end of the electric wire protection cover 2 wound around the electric wire 8 is fixed so as not to move with respect to the electric wire 8, and the protective cover attachment 1 is pushed along the electric wire 8 and moved toward the tip of the opening piece 7. .

At this time, as shown in FIG. 3, the protective cover mounting member 1 is continuously inserted through the insertion hole 3 while the electric wire protection cover 2 is opened with the pushing open piece 7, and the electric wire is inserted from the rear end of the insertion hole 3. Take the protective cover 2 open.

The wire protection cover 2 is rounded to its original shape as it goes away from the rear end of the insertion hole 3, but is guided by the guide groove 5 at a position that is not much apart from the rear end of the insertion hole 3. Due to the presence of the electric wire 8, the electric wire protection cover 2 is rolled around the outer periphery of the electric wire 8, and is continuously covered with the electric wire 8. Thus, the wire protection cover 2 inserted through the insertion hole 3 can be continuously wound around the outer periphery of the wire 8 in a short time.

When the protective cover mounting 1 is moved to the other end of the wire protection cover 2, the protective cover mounting 1 is
The wire protection cover 2 can be quickly and easily detached from the wire protection cover 2 by detaching through the wire protection cover 2, and the wire 8 can be easily covered with the wire protection cover 2 in a short time.

The means for fixing one end of the electric wire protection cover 2 wound around the electric wire 8 so as not to move with respect to the electric wire 8 may be obtained by simply pressing the electric wire protection cover 2 against the electric wire 8. Other temporary fixing means may be used.

[0023]

In summary, according to the present invention, the electric wire can be easily covered with the electric wire protection cover in a short time.
