【Example】

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5.

0010 1 to 5 show one embodiment of the present invention.

[0011] In this embodiment, as shown in FIG. Insert from the same direction as the insertion direction of the core 12 (direction toward the front of the hold case 11). It is designed so that it can be inserted and assembled as a whole.

0012 To explain further, the hold case 11 is made of synthetic resin such as polyacetal. It is integrally molded, with a front core 12, coil bobbin 13, and back core inside. 14 and the pressing member 15 are formed in a hollow shape so that they can be inserted in sequence. Also , the front end of the hold case 11 is connected to the tape sliding surface 12b on the front surface of the front core 12. The coil bobbin 13 is curved and convex to match the media sliding surface. Two terminals 16, 16 protruding upward from the front core 12 are inserted into the front core 12. Two longitudinal grooves 17, 17 are formed to allow insertion in the same direction as the Two terminals 20, 20 of the connector 19 are located in the middle of each of the longitudinal grooves 17. Left and right grooves 18, 18 are formed in which the left and right grooves are engaged. This left-right groove 18 is Reference position where terminal 20 of connector 19 and terminal 16 of coil bobbin 13 are connected It is set in. The front core 12 has a gap 12a in the center. It is preformed as a finished product. The coil bobbin 13 is made of synthetic resin and has an almost rectangular shape. The coil 21 is wound around the rectangular tube portion. At the top of the coil bobbin 13, two L-shaped terminals 16, 16 are connected to each other. The coil 21 is inserted and fixed with the horizontal portion facing backward, and the end of the winding of the coil 21 is Each is connected to the horizontal portion of the terminal 16 by soldering or the like. back core 1 4 is formed into a U-shaped cross section with a pair of front members 14a, 14a. While inserting the other front member 14a into the coil 21 of the coil bobbin 13, , the front end surface of each front member 14a is joined to the rear end surface of the front core 12. Ru. The pressing member 15 is made by pressing a metal plate, and includes a back core 14 and a core. Spring parts 15a, 15a that press the front core 12 and the front core 12 forward It has four engaging protrusions 15b, 15b... on the side surface of the hold case 11. It is attached by elastically engaging the engagement holes 22, 22... bored in the parts. Ru.

[0013] Next, a method for assembling the magnetic head of this embodiment formed as described above will be explained. Ru.

[0014] First, the front core 12, which is a completed product, is placed inside the hold case 11. Insert the tape with the sliding contact surface 12b facing forward. Next, coil bobbin 13 and bag The hold core 14 is inserted into the hold core 11 either integrally with the hold core 14 or separately. child At this time, each terminal 16 of the coil bobbin 13 is inserted into each longitudinal groove 17. do. Finally, the pressing member 15 is moved between the back core 14 and the coil bobbin by the spring portion 15a. Insert the core 13 and front core 12 while pressing them forward. Until the engagement protrusions 15a are elastically engaged with the respective engagement holes 22 of the hold case 11. Press in.

[0015] This completes the assembly of the components into the hold case 11. And each Each component is mounted in its proper position. For example, the front core 12 The end edge of the sliding contact surface 12b is brought into contact with the contact portion 11a of the hold case 11, It is assembled so that the tape sliding surface 12b is properly exposed from the hold case 11. Ru.

[0016] Thereafter, the connector 19 is assembled on the upper surface of the hold case 11. That is, While elastically pushing out only the lower end of each terminal 20 of the connector 19 in the horizontal direction, Insert it in the same direction as the insertion direction of the front core 12 from the open end of the direction groove 17 toward the back. As the terminals 20 are inserted, the lower ends of each terminal 20 elastically narrow in width within the respective left-right grooves 18. After the connector 19 is inserted in this way, each terminal 20 of the connector 19 is inserted into the hold case 11. Push it into. As a result, each terminal 20 has its outer surface attached to the coil bobbin 13. The terminal 16 is fitted into the inner surface of the terminal 16. Solder the contact parts of these terminals 16 and 20 Connect securely.

[0017] As described above, according to this embodiment, first, the tip of the terminal 20 of the connector 19 is holed. In the same direction as the insertion direction of the front core 12 into the front-rear groove 17 on the top surface of the front case 11 Then, the terminals 20 of the connector 19 were elastically engaged with the left-right grooves 18. Afterwards, insert the connector 19 deep into the hold case 11 and connect the terminals of the connector 19. 20 and the terminal 16 of the coil bobbin 13 can be connected. Also, front and back The operation of aligning the terminals 20 of the connector 19 with the opening of the facing groove 17 is similar to the conventional operation. While moving the tip of the terminal 5 in the longitudinal direction, align it with the connection hole 3 in a pinpoint manner. The terminal 20 is moved in the direction orthogonal to the longitudinal direction, and the wires are connected. This is done by matching with the intersection of It can be aligned very easily. Therefore, using the connected operation robot, etc. It is also easy to do this automatically.

[0018] Note that the present invention is not limited to the above embodiments, and may be modified as necessary. be able to.

[0019]
