As shown in FIG. 14, the quick connection terminal 32 is made by bending a metal plate into an L shape. Quick-connect terminal 32
The quick connection plate 32A is inserted into the insertion portion 31B of the terminal body 31. The quick connecting plate 32A includes a quick connecting portion 32B. The quick-connecting portion 32B is provided so as to be inclined with respect to the quick-connecting plate 32A. As shown in FIG. 15, the quick-connecting portion 32B has a V-shaped portion 32C in contact with the core wire 1A of the inserted electric wire 1.
And the groove portion 3 that reinforces the quick-connecting portion 32B so that the quick-connecting portion 32B that is further inclined by the insertion of the core wire 1A does not bend.
With 2D.

The connection plate 32E of the quick-connect terminal 32 is connected to the connection terminal 23 of the transformer section 20. Assembly for this connection process is performed as follows.

The coil 22 is wound around the iron core 21 and the connection terminal 2
3, and the transformer section 20 is assembled.
Further, the transformer section 20 is fixed to the holding section 10. Solder is placed on the upper side of the connection terminals 23, 23.

After the solder is filled, the transformer section 20 is dipped in the varnish so that the transformer section 20 contains the varnish. The varnish prevents the holding part 10 and the transformer part 20 from rusting, and
Fix the 2nd winding to prevent noise.

After dipping in varnish, as shown in FIG.
The solder 301 on the upper part of the solder piled up on the connection terminal 23,
Shave with varnish 311. As a result, the solder 302 and the varnish 312 remain.

After scraping the solder, as shown in FIG. 17, the heated soldering iron tip 201 is applied to the solder 302 of the quick-connect terminal 32, and the solder 211 is caused to flow to the connection terminal 23. At this time,

Keep electrical contact with 2B. That is, the electric wire 1 is connected to the transformer simply by inserting the electric wire 1.

[0015]

By the way, the quick-connect terminal 3
When soldering the second connection plate 32E and the connection terminal 23, as shown in FIG. 21, the varnish 313 remains on the back surface 23B of the connection terminal 23. The transformer unit 20 is the holding unit 10.

In order to facilitate the soldering with the solder, it is necessary to fill the solder before immersing the transformer section 20 in the varnish as shown in FIG. Further, as shown in FIG. 19, it is necessary to fill the solder 303 so as to cover the connection terminals 23.

When a large amount of solder is poured into the connection plate 32E of the quick-connect terminal 32 when the solder is piled up, as shown in FIG. 22, the solder 304 moves from the connection plate 32E to the quick-connect portion 32B.
Flowing toward. As a result, the solder 304 is fastened to the quick connection plate 32.
The fast-connecting parts 32B and 32B of A are closed, and the core wire 1A of the electric wire 1
Becomes impossible to insert.

Further, in order to connect the connection terminal 23 to the connection plate 32E with certainty, solder is spread over almost the entire surface of the connection plate 32E so as to cover the connection terminal 23. For this purpose, the connecting plate 3
The amount of solder on the 2E increases, and it takes time to cool the solder. During this time, if the fast-connecting terminal 32 held is moved,
The solder is cracked, and contact failure between the connection terminal 23 and the quick-connect terminal 32 occurs.

Further, there is a gap for the insulating layer formed by the varnish 313 between the connection terminal 23 and the connection plate 32E,
Welding with a laser beam is difficult, and poor contact occurs even if welding is performed.
