Detailed Description
Hereinafter, embodiments of the marking tube and the marked line material according to the present invention will be described with reference to the drawings. Fig. 1 and 2 are a perspective view and a cross-sectional view, respectively, showing a marked pipe wire according to an embodiment of the present invention. Fig. 2 shows a cross section of the marked pipe wire shown in fig. 1, the cross section being perpendicular to the axial direction of the marked pipe. Fig. 3 and 4 are a perspective view and an expanded view showing the marker tube shown in fig. 1 and 2, respectively.
In fig. 1, a marked pipe material 1 includes a wire 2 and a marking pipe 3 attached to the wire 2. The wire 2 is, for example, a wire material connected to a terminal of a panel product such as a distribution board. The marking tube 3 is attached to the wire 2 by inserting the wire 2 inside.
As shown in fig. 2 and 3, the marker tube 3 includes a sheet member 4 bent into a cylindrical shape. The sheet member 4 is formed of an elastically deformable material, for example, a thermoplastic resin such as soft polyvinyl chloride. As shown in fig. 2 and 4, the sheet member 4 includes: a main body region 5 having a 1 st end 5a and a 2 nd end 5b provided on opposite sides to each other in a circumferential direction D1 of the marker tube 3; a 1 st concavo-convex region 6 connected to the 1 st end 5a of the body region 5; and a 2 nd concave-convex region 7 connected to the 2 nd end 5b of the main body region 5. As shown in fig. 3, the sheet member 4 forms the cylindrical marker tube 3 by the engagement of the 1 st uneven region 6 and the 2 nd uneven region 7 with each other.
In the illustrated example, the 1 st uneven region 6 has a plurality of 1 st convex portions 6a protruding from the main body region 5, and a plurality of 1 st concave portions 6b provided between the 1 st convex portions 6 a. Further, the 2 nd concave-convex region 7 has a plurality of 2 nd convex portions 7a protruding from the main body region 5, and a plurality of 2 nd concave portions 7b provided between the 2 nd convex portions 7 a. The 1 st convex portion 6a extends into the 2 nd concave portion 7b, and the 2 nd convex portion 7a extends into the 1 st concave portion 6b, whereby the 1 st concave-convex region 6 and the 2 nd concave-convex region 7 are engaged with each other.
As described above, the sheet member 4 is formed of an elastically deformable material. The 1 st concave-convex region 6 and the 2 nd concave-convex region 7 can be bent toward the inside of the main body region 5 within the elastic deformation range. As a result, as shown in fig. 5C and 5D to be referred to later, an opening M through which the wire 2 can pass can be formed between the 1 st concave-convex region 6 and the 2 nd concave-convex region 7. Further, the 1 st concave-convex region 6 and the 2 nd concave-convex region 7 are capable of bending toward the outside of the main body region 5 within the elastic deformation range. As a result, as shown in fig. 6D referred to later, an opening M through which the wire 2 can pass can be formed between the 1 st concave-convex region 6 and the 2 nd concave-convex region 7. Further, the main body region 5 can be deformed so as to expand its inner diameter (diameter of inscribed circle) within the elastic deformation range. As a result, as shown in fig. 7 to be referred to later, the marking tube 3 can have its inner diameter (diameter of the inscribed circle) enlarged in accordance with the outer diameter of the wire rod 2 inserted through the marking tube 3.
In the illustrated example, as shown in fig. 2 and 3, the 1 st projection 6a passes through the 2 nd recess 7b and protrudes into the main body region 5. The 2 nd projection 7a passes through the 1 st recess 6b and projects into the inside of the main body region 5. Further, the front end of the 1 st projection 6a and the front end of the 2 nd projection 7a are separated from the inner circumferential surface 5s of the body region 5. As a result, as shown in fig. 2, the marker tube 3 can be held even on the wire rod 2 having an outer diameter (diameter of the circumscribed circle) smaller than the inner diameter (diameter of the inscribed circle) of the main body region 5 of the marker tube 3. In this case, in a state where the wire 2 is inserted inside the marking tube 3, at least a part of the main body region 5, at least a part of the 1 st convex portion 6a, and at least a part of the 2 nd convex portion 7a are in contact with the wire 2, whereby the marking tube 3 is held on the wire 2.
Further, as shown in fig. 2, in the illustrated example, a recess is formed in the outer peripheral surface 3t of the marker tube 3 at an intersection portion C where the 1 st convex portion 6a and the 2 nd convex portion 7a intersect, as viewed from a direction D2 (hereinafter referred to as "axial direction") extending from the axis Ax of the marker tube 3. This makes it easy to press the wire 2 against the intersection C of the marker tube 3 when the marker tube 3 is attached to the wire 2.
Next, a method of attaching the marker tube 3 to the wire 2 will be described with reference to fig. 5. First, as shown in fig. 5A, the wire 2 is made to face the outer peripheral surface Ct of the intersection C of the marker tube 3. At this time, the direction D2 in which the intersection C extends coincides with the direction in which the wire rod 2 extends. Next, as shown in fig. 5B, the wire 2 is pressed against the outer peripheral surface Ct of the intersection portion C of the marker tube 3. Then, as shown in fig. 5C, the 1 st convex portion 6a and the 2 nd convex portion 7a are bent by the pressing force of the wire 2. Specifically, the 1 st projection 6a and the 2 nd projection 7a are bent inward of the main body region 5 while being pulled out from the 2 nd recess 7b and the 1 st recess 6b, respectively. Thereby, an opening M through which the wire 2 can pass is formed between the 1 st convex portion 6a and the 2 nd convex portion 7 a. Then, as shown in fig. 5D, the wire 2 is passed through the opening M. Finally, as shown in fig. 5E, the wire 2 passing through the opening M is arranged inside the 1 st projection 6a and the 2 nd projection 7 a. In the illustrated example, the 1 st convex portion 6a and the 2 nd convex portion 7a are displaced from the positions shown in fig. 5D to the positions shown in fig. 5E by their restoring forces. At this time, the 1 st convex portion 6a enters the 2 nd concave portion 7b, the 2 nd convex portion 7a enters the 1 st concave portion 6b, and the opening M is closed. At this time, the central portion of the body region 5 in the circumferential direction D1, the tip of the 1 st projection 6a, and the tip of the 2 nd projection 7a abut against the wire 2, and the marker tube 3 is held on the wire 2.
According to such a mounting method, the marker tube 3 can be mounted to the wire 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product, the marking tube 3 can be attached to the wire 2 while maintaining the state in which the wire 2 is connected to the terminal. This increases the degree of freedom in wiring work.
Next, a method of detaching the marker tube 3 from the wire rod 2 will be described with reference to fig. 6. First, as shown in fig. 6A, the wire 2 inserted through the marker tube 3 is pressed against the inner peripheral surface Cs of the intersection C of the marker tube 3 as shown in fig. 6B. Next, as shown in fig. 6C and 6D, the 1 st convex portion 6a and the 2 nd convex portion 7a are bent by the pressing force of the wire 2. Specifically, the 1 st projection 6a and the 2 nd projection 7a are pulled out from the 2 nd recess 7b and the 1 st recess 6b, respectively, and displaced outward of the main body region 5. Thereby, an opening M through which the wire 2 can pass is formed between the 1 st convex portion 6a and the 2 nd convex portion 7 a. Then, as shown in fig. 6D and 6E, the wire 2 is passed through the opening M. In the illustrated example, the 1 st convex portion 6a and the 2 nd convex portion 7a are displaced from the positions shown in fig. 6D to the positions shown in fig. 6E by their restoring forces. At this time, the 1 st convex portion 6a enters the 2 nd concave portion 7b, the 2 nd convex portion 7a enters the 1 st concave portion 6b, and the opening M is closed.
According to such a detaching method, the marker tube 3 can be detached from the wire rod 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product or the like, the marker tube 3 can be detached from the wire 2 without detaching the wire 2 from the terminal or the like. This increases the degree of freedom in wiring work.
As described above, the sheet member 4 forming the marker tube 3 is elastically deformable, and the inner diameter (diameter of the inscribed circle) of the marker tube 3 can be enlarged in accordance with the outer diameter of the wire 2 inserted through the marker tube 3. As a result, as shown in fig. 7A to 7C, the marker tube 3 can be attached to various wire rods 2 having different outer diameters. In the state where the marker tube 3 is attached to the wire rod 2, the 1 st projection 6a and the 2 nd projection 7a may or may not extend into the 2 nd recess 7b and the 1 st recess 6b, respectively. In any case, the main body region 5, the 1 st projection 6a, and/or the 2 nd projection 7a are brought into contact with the wire 2 by the restoring force thereof, and the marking tube 3 is held on the wire 2.
The method of attaching the marker tube 3 to the wire 2 is not limited to the above-described attachment method. That is, as shown in fig. 8, the marker tube 3 can be attached to the wire rod 2 by inserting the tip of the wire rod 2 into the marker tube 3 from one end portion of the marker tube 3 in the axial direction D2. The method of detaching the marker tube 3 from the wire rod 2 is not limited to the above-described detaching method. The marker tube 3 can also be detached from the wire rod 2 by performing the reverse operation to the method of attaching the marker tube 3 shown in fig. 8. That is, the marker tube 3 can be detached from the wire rod 2 by pulling out the wire rod 2 from one end portion of the marker tube 3 in the axial direction D2.
As described above, according to the present embodiment, the marker tube 3 is the marker tube 3 through which the wire 2 is inserted on the inner side, and includes the sheet member 4 formed in a cylindrical shape. The sheet member 4 has: a main body region 5 having a 1 st end 5a and a 2 nd end 5b provided on opposite sides to each other in a circumferential direction D1 of the marker tube 3; a 1 st concavo-convex region 6 connected to the 1 st end 5a of the body region 5; and a 2 nd uneven region 7 connected to the 2 nd end 5b of the main body region 5, the 1 st uneven region 6 and the 2 nd uneven region 7 being engaged with each other.
According to the marking tube 3, the marking tube 3 can be attached to and detached from the wire rod 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product, the marking tube 3 can be attached to the wire 2 while maintaining the state in which the wire 2 is connected to the terminal. Further, even after the wire 2 is connected to the terminal of the coil product or the like, the marking tube 3 can be detached from the wire 2 without detaching the wire 2 from the terminal or the like. This increases the degree of freedom in wiring work.
Specifically, the 1 st uneven region 6 has a plurality of 1 st raised portions 6a projecting from the main body region 5, and a plurality of 1 st recessed portions 6b provided between the 1 st raised portions 6 a. The 2 nd concave-convex region 7 includes a plurality of 2 nd convex portions 7a protruding from the main body region 5 and protruding into the 1 st concave portion 6b, and a plurality of 2 nd concave portions 7b provided between the 2 nd convex portions 7a and into which the 1 st convex portion 6a protrudes. The 1 st projection 6a passes through the 2 nd recess 7b and projects into the inside of the main body region 5, and the 2 nd projection 7a passes through the 1 st recess 6b and projects into the inside of the main body region 5.
Further, according to the present embodiment, the leading end of the 1 st projecting portion 6a and the leading end of the 2 nd projecting portion 7a are separated from the inner circumferential surface 5s of the main body region 5. Thus, the marker tube 3 can be held even on the wire rod 2 having an outer diameter (diameter of the circumscribed circle) smaller than the inner diameter (diameter of the inscribed circle) of the main body region 5 of the marker tube 3.
Further, according to the present embodiment, a recess is formed in the outer peripheral surface 3t of the marker tube 3 at the intersection C where the 1 st convex portion 6a and the 2 nd convex portion 7a intersect, as viewed from the axial direction D2 of the marker tube 3. This makes it easy to press the wire 2 against the intersection C of the marker tube 3 when the marker tube 3 is attached to the wire 2.
Further, according to the present embodiment, the 1 st concave-convex region 6 and the 2 nd concave-convex region 7 are bendable toward the inside of the body region 5 within the elastic deformation range, so that the opening M through which the wire 2 can pass can be formed between the 1 st concave-convex region 6 and the 2 nd concave-convex region 7. This enables the marker tube 3 to be attached to the wire rod 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product, the marking tube 3 can be attached to the wire 2 while maintaining the state in which the wire 2 is connected to the terminal. This increases the degree of freedom in wiring work.
Further, according to the present embodiment, the 1 st concave-convex region 6 and the 2 nd concave-convex region 7 are bendable toward the outside of the main body region 5 within the elastic deformation range, so that the opening M through which the wire 2 can pass can be formed between the 1 st concave-convex region 6 and the 2 nd concave-convex region 7. This enables the marker tube 3 to be detached from the wire rod 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product or the like, the marker tube 3 can be detached from the wire 2 without detaching the wire 2 from the terminal or the like. This increases the degree of freedom of the wiring operation.
Further, according to the present embodiment, the marked pipe wire 1 includes the above-described marking pipe 3 and the wire 2, and in a state where the wire 2 is inserted inside the marking pipe 3, at least a part of the main body region 5, at least a part of the 1 st convex portion 6a, and at least a part of the 2 nd convex portion 7a are in contact with the wire 2, whereby the marking pipe 3 is held on the wire 2.
In such a marked pipe wire 1, the marking pipe 3 is held on a wire 2 having an outer diameter (diameter of circumscribed circle) smaller than the inner diameter (diameter of inscribed circle) of the main body region 5 of the marking pipe 3.
Further, according to the present embodiment, a method of attaching the marker tube 3 is a method of attaching the marker tube 3 to the wire rod 2, and includes: pressing the wire rod 2 against the outer peripheral surface Ct of the marker tube 3 at the intersection C where the 1 st convex portion 6a and the 2 nd convex portion 7a intersect as viewed in the axial direction D2 of the marker tube 3; a step of drawing the 1 st convex portion 6a and the 2 nd convex portion 7a from the 2 nd concave portion 7b and the 1 st concave portion 6b by the pressing force of the wire 2, respectively, and bending the 1 st convex portion 6a and the 2 nd convex portion 7a inward, thereby forming an opening M between the 1 st convex portion 6a and the 2 nd convex portion 7a and passing the wire 2 through the opening M; and a step of disposing the wire 2 that has passed through the opening M inside the 1 st and 2 nd protrusions 6a and 7 a.
According to such a method of attaching the marker tube 3, the marker tube 3 can be attached to the wire rod 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product, the marking tube 3 can be attached to the wire 2 while maintaining the state in which the wire 2 is connected to the terminal. This increases the degree of freedom in wiring work.
Further, according to the present embodiment, the method of detaching the marking tube 3 is a method of detaching the marking tube 3 from the wire rod 2 to which the marking tube 3 is attached, and includes: pressing the wire rod 2 against the inner circumferential surface Cs of the marker tube 3 at the intersection C where the 1 st convex portion 6a and the 2 nd convex portion 7a intersect as viewed in the axial direction D2 of the marker tube 3; and a step of displacing the 1 st convex portion 6a and the 2 nd convex portion 7a outward by the pressing force of the wire 2 to form an opening M between the 1 st convex portion 6a and the 2 nd convex portion 7a, and passing the wire 2 through the opening M.
According to such a method of detaching the marker tube 3, the marker tube 3 can be detached from the wire rod 2 at a desired timing. For example, even after the wire 2 is connected to a terminal of a coil product or the like, the marker tube 3 can be detached from the wire 2 without detaching the wire 2 from the terminal or the like. This increases the degree of freedom in wiring work.
The above-described embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the registration request range of the invention and its equivalent range. It is needless to say that the above embodiments and modifications may be appropriately combined within the scope of the present invention.
