Description

[Detailed description of the invention] The present invention relates to a coil wiring component that holds an external lead wire that is attached to the surface of a coil component composed of windings, and in which the external lead wire is subjected to external forces such as tension or rotation. The object of the present invention is to provide a device that will not break due to external force applied to the connection portion with the coil component even if external force is applied thereto.

As shown in Fig. 1, conventional coil wiring components have a holding substrate 1 made of insulating paper, synthetic resin, etc., with a through hole 2 through which an external lead wire is inserted and a small hole 3 through which only the core wire is inserted. A plurality of lead wires 4 and their core wires 5 are provided in the holding substrate 1 at intervals as shown in FIG. The adhesive tape 6 is assembled into the small hole 3 and attached to one side of the holding board 1, and the adhesive tape 9 is attached to the outer peripheral surface of the coil 8, which is constructed by winding the coil bobbin 7 as shown in FIG. The lead wire 10 of the coil 8 and the core wire 5 are wound together and connected by soldering.
), when an external force such as rotation or tension in the c direction is applied,
The connecting portion between the core wire 5 and the coil lead wire 10 moved in directions d and e, and was broken near the root A of the coil lead wire 10 shown in the enlarged view of FIG. 4.

The present invention eliminates the above-mentioned drawbacks of the prior art.

Embodiments of the present invention will be described below with reference to FIGS. 5 to 8.

First, as shown in FIG. 5, a plurality of conductive layers 12 are formed at regular intervals on one side of a holding substrate 11 made of a synthetic resin such as a polyester film by etching or pasting, and a portion including the conductive layers 12 is As shown in FIG. 6, a through hole 1 through which a core wire 14 of an external lead wire 13 is inserted.
5, the lead wire 13 for external extraction is placed along the conductive layer 12 side as shown in FIG. 12 are connected with solder 16, and the holding board 11 and the lead wire 13 for external extraction are combined.

As shown in FIG. 8, the coil wiring component 17 configured in this manner is fixed to the outer circumference of a coil 19 formed by winding a coil bobbin 18 with an adhesive tape 20, and is attached to the lead wire 21 of this coil 19. It is used by winding the core wire 14 protruding from the holding substrate 11 and connecting it by soldering.

In such a usage mode, the external lead wire 13
Even if an external force such as rotation or tension is applied in directions a, l), and c, the core wire 14 of the lead wire 13
Since the connecting portion between the core wire 14 and the coil lead wire 21 does not move in the d and e directions, the connecting portion between the core wire 14 and the coil lead wire 21 does not move in the d and e directions.

Therefore, disconnection of the coil lead wire 21 can be completely prevented.

Since the coil wiring component of the present invention is configured as described above, no matter which direction the external lead wire is drawn out, external force is applied to the connection between the core wire of the external lead wire and the coil lead wire. In addition, disconnection of the coil lead wire made of thin wire can be completely prevented, making it highly reliable, which is of great practical value.
