Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to magnetic heads, and in particular to magnetic recording and reproducing devices using rotating heads. The present invention relates to a composite magnetic head mounted thereon.

0002

[Conventional technology]

Conventionally, magnetic recording and reproducing devices using rotating heads include, for example, video tape records. It is used as a composite magnetic head in this video tape recorder device. , a magnetic head shown in FIG. 2 is known, and will be described below.

0003 As shown in the figure, the conventional composite magnetic head 1 includes a pair of head chips 2a and 2b. are separated by a slit 3, and head chips 2a and 2b are fixedly disposed at the tips. The head base 5 has head chip mounting parts 4a and 4b integrally formed on one side. , a printed circuit board 6 disposed on this head base 5, and head chips 2a, 2. b, and is locked to the stepped portions 7a, 7b of the head chip mounting portions 4a, 4b. It consists of a coil wire 9 which is electrically connected to the electrode part 8 of the printed circuit board 6 in a state Ru. Note that reference numeral 10 indicates a mounting hole of the head base 5.

0004

[Problem that the idea aims to solve]

However, in the conventional composite magnetic head 1 described above, the head chip 2 In the lead-out connection of the coil wires wound around a and 2b, the coil wire 9 is connected to the head chip The electrode portions of the printed circuit board 6 are connected to the step portions 7a and 7b of the attachment portions 4a and 4b and routed. 8 is conductively fixed by soldering or the like.

[0005] For this reason, as shown in FIG. 3, for example, when the coil wire 9 is soldered, the coil wire 9 The coil wire 9 easily comes off from the stepped portions 7a and 7b, and is soldered in this detached state. When corrected, the coil wire 9 is removed at the stepped portions 7a and 7b of the head chip mounting portions 4a and 4b. A problem arises in that the insulating enamel peels off due to rubbing, resulting in poor insulation of the coil wire 9. was.

[0006] This invention was devised in view of the above-mentioned problems, and is When soldering the coiled wire to the printed circuit board electrode, ensure that the lead-out is properly routed. We aim to provide a composite magnetic head that prevents poor insulation of the coil wire by applying soldering. purpose.

[0007]

[Means to solve the problem]

Therefore, as a means to solve the above-mentioned problems, the present invention has been developed to In a composite magnetic head equipped with a chip, the head base of the head is The winding insertion hole is provided in the top mounting portion.

[0008]

[Effect]

The coil wire wound around the head chip should be inserted through the insertion hole provided in the head chip mounting part. It will be led out through the wire and soldered to the electrode of the printed circuit board, and the soldering At this time, the coil wire is reliably positioned and soldered.

[0009]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings.

0010 FIG. 1 shows a front view of a composite magnetic head 20 according to the present invention. As shown, The composite magnetic head 20 includes a pair of head chips 21a and 21b, and a pair of head chips 21a and 21b. The head is separated by a slit 22 so that the tips 21a and 21b are attached to the tip. The chip mounting parts 23a, 23b and the head chip mounting parts 23a, 23b are integrated. A head base 24 that is formed and arranged in a manner that is It is wound around a printed circuit board 25 having a pole part 26 and each head chip 21a, 21b. A coil wire 27 whose one end is soldered to the electrode part 26 of the printed circuit board 25, and The head chip is used to lead out the coil wire 27 to the electrode section 26 of the printed circuit board 25. The insertion hole 28 provided approximately in the middle of the mounting portions 23a and 23b and the head base 24 and a mounting hole 29 provided approximately in the center of the flat surface of the holder.

[0011] That is, the composite magnetic head 20 according to the present invention has windings around the head chips 21a and 21b. The twisted coil wire 27 is passed through the insertion holes 2 provided in the head chip mounting parts 23a and 23b. 8 to conductively connect to the electrode portion 26 of the printed circuit board 25. It is something that

0012

[Effect of the idea]

Therefore, the composite magnetic head having the above-mentioned configuration has a The coil wire passes through the insertion hole provided in the head chip mounting part and connects to the electrode part of the printed circuit board. Since it will be soldered, position the coil wire and perform the soldering work securely. It is said that it is possible to prevent the occurrence of poor insulation of the coil wire. The effect is obtained.
