Description

  The present invention relates to a wire winding adhesive tape and a wire harness that are wound around a group of wires routed in a vehicle or the like.

  2. Description of the Related Art Conventionally, a wire harness used for a vehicle such as an automobile arranges a plurality of electric wires on an assembly work board corresponding to a vehicle routing route, and bundles the arranged electric wires into an electric wire group. They are bundled by spirally winding an adhesive tape around the group. In the wiring work, the adhesive tape is wound by manually winding a tape roll around the electric wire group for each predetermined range according to the form of the wire harness.

  However, in the wiring work of the wire harness, when the wire tape is bound and protected by winding the adhesive tape around the wire group in a half-wrap manner, an appearance inspection is performed to check whether or not the half-wrap winding is accurately performed. It took time and effort.

  Therefore, for example, by attaching a mark line that is different from the ground color of the tape body to the adhesive tape continuously in the length direction at the center in the width direction, half-flap winding is performed based on the mark line. Thus, there is one that improves the quality of half-wrap winding (see, for example, Patent Document 1).

  The pressure-sensitive adhesive tape is half-wrapped so that the mark line at the center in the width direction is exactly hidden during half-wrapping. Therefore, when visual inspection is performed on the wire harness that is half-wrapped with adhesive tape, if the mark line is exposed to the outside, the adhesive tape on the front winding side is overlapped by the adhesive tape on the rear winding side only by half or less in width. Can be identified at a glance, and it can be detected that the half wrap is not completely formed.

  Hereinafter, embodiments of an adhesive tape for winding an electric wire and a wire harness according to the present invention will be described with reference to the drawings. FIG. 1 thru | or FIG. 3 is a figure which shows one Embodiment of the adhesive tape for wire winding based on this invention, and a wire harness.

  1 and 2, the wire winding adhesive tape 1 is wound around the outer periphery of a wire harness 10 having an electric wire group 2 composed of a plurality of electric wires, and this wire harness 10 is routed to a vehicle such as an automobile. It is what is done.

  The wire winding pressure-sensitive adhesive tape 1 includes a tape body 5 formed from an insulating resin. The surface of the tape body 5 is provided with a first mark line 3 and a second mark line 4, and a tape. An adhesive layer 6 is provided on the entire back surface of the main body 5.

  The first mark line 3 has a color different from the ground color of the tape body 5. For example, the first mark line 3 is formed by being colored white or yellow on the tape body 5 whose ground color is black or dark blue.

  The second mark line 4 has a color different from the ground color of the tape body 5 and the color of the first mark line 3. For example, the second mark line 4 is formed by being colored red on the tape body 5 whose ground color is black or dark blue. As will be described later, when half-wrapped, the first mark line 3 is hidden by the wire winding adhesive tape 1 on the rear winding side. On the other hand, the second mark line 4 is exposed to the outside and is noticeable in the completed state of the wire harness 10, and is colored with a color that is inconspicuous considering the appearance.

  The second mark line 4 is configured to have a line width narrower than that of the first mark line 3. For example, the first mark line 3 has a line width of about 2.0 to 3.0 mm, whereas the second mark line 4 has a line width of about 0.5 to 1.0 mm. The In the present embodiment, the first mark line 3 has a line width of 2.0 mm, whereas the second mark line 4 has a line width of about 0.5 to 1.0 mm. The

  When half wrap winding (1/2 wrap winding) is performed, the first mark line 3 is arranged such that one end line 3A thereof is located at a half of the tape width and the other end line 3B is the tape. The second mark line 4 is attached within the range of position 1/2 to position 1 of the tape width. That is, the first mark line 3 at the time of 1/2 wrap winding defines the position of 1/2 of the tape width at the end line 3A, and the end line 3B is located with respect to the entire area of the wrap margin to be wound later. It may be a position. Further, the second mark line 4 at the time of 1/2 wrap winding may be at any position with respect to the entire remaining range excluding the lapping margin. The lap allowance described above is a reference lap allowance (1/2 wrap allowance) in the case of 1/2 wrap winding, and the allowable wrap allowance is from position 0 to the second mark line 4.

  In the present embodiment, the tape width W is 25 mm, and one end line 3A of the first mark line 3 is one end in the width direction of the tape body 5 on the rear winding side (hereinafter referred to as “tape end portion”). 1A ”), the line width is 2.0 mm, and the other end line 3B is 10 from the other end in the width direction of the tape body (hereinafter referred to as“ tape end 1B ”). Placed at 5 mm. The second mark line 4 is arranged such that one end line thereof is separated from the end line 3A by, for example, 3.0 to 5.0 mm, and the line width is about 0.5 to 1.0 mm. It is. In addition, the numerical value of these dimensions is an illustration, Comprising: It is not limited to this.

  At this time, one end line of the second mark line 4 is arranged at a position separated by 3.0 to 5.0 mm from the end line 3A. When it is closer to the end line 3A than 0 mm, it is difficult to quickly perform the manual winding operation. Further, if one end line of the second mark line 4 is separated from 5.0 mm, the consumption amount of the wire winding pressure-sensitive adhesive tape 1 tends to increase due to excessive overlapping. The tape end 1A indicates the position 1 and the tape end 1B indicates the position 0.

  Here, the wire harness 10 according to the present embodiment will be described. The wire harness 10 is also referred to as a cable harness, and is a collective part formed by bundling a plurality of electric wires used for power supply and signal communication.

  The wire harness 10 is composed of an electric wire group 2 in which an electric wire winding adhesive tape 1 is wound around an outer periphery. As shown in FIG. 2, in the wire harness 10, the wire group 2 has a tape end 1 </ b> A of the wire winding adhesive tape 1 on the rear winding side and the wire winding adhesive tape 1 on the front winding side. The wire winding adhesive tape 1 is continuously wound so as to be positioned between the first mark line 3 and the second mark line 4.

  Here, with reference to FIG. 3, the process of winding the wire winding adhesive tape 1 around the outer periphery of the electric wire group 2 to create the wire harness 10 will be described.

  First, as shown in FIG. 3, the wire group 2 is held by a fixture H so that the wire winding adhesive tape 1 can be easily wound.

  Next, as shown in FIGS. 3A and 3B, the wire winding adhesive tape 1 is attached to the outer periphery of the wire group 2 held by the fixture H, and the wire winding adhesive on the rear winding side. The tape 1 is continuously wound so that the tape end 1A of the tape 1 is positioned between the first mark line 3 and the second mark line 4 of the wire winding adhesive tape 1 on the first winding side.

  And when the range which needs to be coat | covered among the electric wire groups 2 is finished winding with the adhesive tape 1 for electric wire winding, as shown in FIG.3 (c), the adhesive tape 1 for electric wire winding will be cut | disconnected and a wire harness will be cut | disconnected. 10 is completed.

  The wire winding adhesive tape 1 according to the present embodiment is wound around the wire group 2 so as to hide the first mark line 3 and not to exceed the second mark line 4. It is possible to make sure that there are no overlying parts and no overlying parts. Therefore, the wire-wrapping pressure-sensitive adhesive tape 1 can be overlapped with an appropriate area for half-wrap winding, and the consumption of the wire-winding pressure-sensitive adhesive tape 1 can be reduced.

  Further, the first mark line 3 and the second mark line 4 are made different in color, and the second mark line 4 is made inconspicuous with respect to the ground color of the tape body 5 to wrap. The appearance after being wound can be improved.

  In addition, by narrowing the width of the second mark line 4, the second mark line 4 can be made inconspicuous in appearance after half-wrap winding, and the appearance can be improved.

  Here, the modification of the adhesive tape for wire winding which concerns on this Embodiment is demonstrated.

May be attached so that the other end line 3B is disposed within the range of position 0 to position 1/3 of the tape width. And the 2nd mark line 4 may be attached | subjected in the range of the position 1/3-position 1 of a tape width.

  As a second modification, as shown in FIG. 4 (b), when performing wrap winding to overlap two-thirds of the tape width, the first mark line 3 has one end line 3A. It may be attached so that the other end line 3B is arranged within the range of the position 0 to the position 2/3 of the tape width. And the 2nd mark line 4 may be attached | subjected within the range of position 2/3-position 1 of a tape width.

  For example, by arranging the other end line 3B in the immediate vicinity of the inside of the portion (wrap margin) where the first mark line 3 is overlapped in the wrap winding, any wrap winding can be handled.

  More specifically, for example, for 1/3 wrap winding, the first mark line has one end line at a position 1/3 of the tape width and the other end line at the tape width. It arrange | positions in the range of position 0-position 1/3, and is arrange | positioned in the inner side of the 1/3 overlap part. If wrapping is performed so as to hide the first mark line, 1/3 wrapping can be performed.

  For 2/3 wrap winding, the first mark line has one end line at a position 2/3 of the tape width and the other end line at a position 0 to position 2 / the tape width. Is disposed within the range of 3 and is disposed in the immediate vicinity of the two-third overlapped portion. If wrapping is performed so as to hide the first mark line, 2/3 wrapping can be performed.
