Description

[Detailed explanation of the idea] The present invention relates to a winding body for winding a coil wire around a bobbin.

In this type of conventional device, as shown in FIG. 1, after a coil wire is wound around a bobbin 1, an insulating tape 2 is wrapped around the outer circumference of the coil to maintain the wound state of the coil.

After that, after winding both ends 3, 3 of the coil around the lead wires 4, 4, respectively, the ends with no ends are fixed, and the ends with ends of both ends are fixed with the connection parts separated, so as shown in Fig. 2. A second insulating tape 5 is wrapped around the outer circumference of the coil.

Therefore, not only is it necessary to perform the taping process twice, but also it is extremely troublesome to securely connect the coil end 3 to the lead wire 4.
The work efficiency was poor.

Another conventional device is disclosed in Japanese Utility Model Application Publication No. 50-11046.

This involves attaching a flexible strip with a relay terminal formed from a printed base to the outer circumference of a coil wound around a bobbin, and soldering the coil terminal and lead wire to the relay terminal. It is something.

However, relay terminals formed from printed bases of flexible strips have low mechanical strength and are susceptible to heat, so connections such as coil terminals can be made in a short time, but Because this relay terminal part is fragile,
As disclosed in the publication, in order to protect the relay terminal portion, the relay terminal portion is covered with a special cover.

For this reason, this conventional device also uses the flexible strip and the cover integrally in place of the two types of insulating tapes 2 and 5 shown in FIGS. There are drawbacks similar to those shown in Figure 2.

The present invention has been devised in view of these points, and specific examples of the present invention will be explained below based on the drawings.

3 and 4, forming a coil 8 in which a coil wire is wound around the central tube 7 of the bobbin 6 is the same as in the conventional device, but a strip 10 is provided around the outer circumference 9 of the coil 8. It is characterized in that the strip 10 is partially fixed on the outer periphery of the coil 8 by winding the coil.

The strip 10 is a flexible resin thin piece 11 with a pair of conductive members 13 and 13 that are parallel to each other except for the starting end 12. The conductive members may be printed conductive foil or wire-shaped conductive wire. But that's fine.

An insulating sheet 14 is placed on each conductive member 13 as shown in FIG.
is crowned.

The base ends 15, 15 of the conductive member are connected to both ends of the coil 8 wound around the bobbin 6, and the conductive member 13.
The starting end 12 where the coil 13 does not exist is wound one or more turns so as to cover the outer circumference 9 of the coil 8 to maintain the coiled state of the coil.

In the embodiment shown in FIG. 3, the starting end 12 is fixed to the outer circumference 9 of the coil 8 with adhesive to prevent the strip 10 from unwinding.

7 and 8 show another specific example of fixing the strip 10 on the outer periphery of the coil 8, in which a notch 16 or 17, 17 is provided on the side edge of the strip 10, and in FIG. In FIG. 8, a case 19 for storing the bobbin 6 is provided with an insertion hole 20 for the strip 10, and a hook communicating with the insertion hole is used. Part 2
1 is provided, and notches 17 and 1 are provided at both side edges 22 and 22 of the hooking part.
7.

As described above, according to the configuration of the present invention, since the flexible resin thin strip is provided with a pair of conductive members that are parallel to each other except for the starting end thereof, the proximal end of the conductive member is wound around the bobbin. By connecting both ends of the coil and fixing the strip partially on the outer periphery of the coil, the base ends of the pair of conductive members are covered by the strip. It has the same function as the second taping, and also allows the starting end to be wrapped and wound around the outer circumferential body of the coil, and the coiled state of the coil can be maintained by fixing the strip as described above. Achieves the same function as the first taping of the conventional device.

Therefore, by using the strip, it is possible to omit the two-time taping operation of the conventional device, and it is also possible to simplify the operation of winding and fixing both ends of the coil around the lead wire, respectively, and the proximal end of the conductive member can be Since it is connected to both ends of the coil, the connecting part, that is, the strip at the base end becomes fragile, but this connecting part is covered by the other part of the belt, and the connecting part can be protected. Work efficiency can be improved, which has great practical effects.
