Abstract

(57) [Abstract] [Purpose] To provide a ferrite core mounting structure that is easy to assemble and can improve the positioning accuracy of the ferrite core. [Constitution] Case 5 having semicircular groove 7 and hook 8
Insert the ferrite core 2 that has passed through the lead wire 1, and hold the ferrite core 2 with the ferrite core retainer 6 and hook 8.
Then, the ferrite core 2 is fixed to the specified mounting position 12.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ferrite core mounting structure in a printer.

[0002]

[Prior art]

 In the conventional ferrite core mounting method, as shown in FIGS. 4 and 5, the lead wire 1 is wound around the ferrite core 2 once, and the length from the connector 10 is measured and fixed at the specified mounting position 12. (Conventional structure 1) Alternatively, as shown in FIGS. 6 and 7, the lead wire 1 is passed through the ferrite core 2, the heat shrink tube 3 is covered on the ferrite core 2, and both ends of the heat shrink tube 3 are bundled with the band band 4. Then, the ferrite core 2 was fixed to the specified mounting position 12 from the connector 10. (Conventional structure 2)

[0003]

[Problems to be solved by the device]

 However, this conventional structure has the following problems.

First, the ferrite core mounting method is complicated and requires a lot of time for mounting.

Secondly, the ferrite core had to be mounted at a specified mounting position from the connector, which made positioning difficult.

Therefore, the present invention solves such a problem, and its purpose is to simplify the ferrite core mounting method and improve the positioning accuracy by fixing the ferrite core mounting position. Is to let.

[0007]

[Means for Solving the Problems]

 The ferrite core mounting structure according to the present invention is characterized by having a case having a semicircular groove and a hook and a ferrite core retainer.

[0008]

【Example】

 The details of the present invention will be described below based on the illustrated embodiments.

1 to 3 show an embodiment of the present invention, in which a case 5 has a semicircular groove 7 and a hook 8. Insert the ferrite core 2 through the lead wire 1 into the semicircular groove 7 of the case 5, and press the ferrite core 2 so that the square hole 9 of the ferrite core retainer 6 fits into the hook 8 of the case 5, and the ferrite core 2 is inserted. Fix 2

The position of the semicircular groove 7 is set to a prescribed mounting position 12 from the connector 10 in a state where the connector 10 is connected to the substrate 11 in advance.

[0011]

[Effect of device]

 The structure of the present invention having the contents described above has the following effects.

First, the ferrite core can be easily attached, and the attachment time can be shortened.

Second, since the mounting position of the ferrite core is determined by the semicircular groove, the positioning accuracy can be improved.
