Abstract

(57) [Abstract] [Purpose] To provide a common mode coil that improves workability by separating the core case and the terminal block and prevents damage to the terminal block. [Structure] A core case and a terminal block of a common mode coil, wherein protrusions 5 and 6 are provided on two sides of the core case 4.
Is provided on the lower side of the core case to prevent the coil from shifting.
And a groove 11 for preventing the coil from slipping on the bottom of the terminal block 9 and a snap groove 1 having a snap mechanism on both side surfaces.
The two hooks 10 and 12 having the number 4 are provided, the two convex portions 5 and 6 of the core case are fixed by the hooks 10 and 12, and the deviation preventing convex portion 7 and the coil deviation preventing concave portion 11 are fitted. It is the core case and terminal block of the common mode coil that fits together.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a core case and a terminal block of a common mode coil.

[0002]

[Prior art]

 As shown in FIG. 4, 1 is a core case, 2 is a terminal block, and 3 is a core case and a terminal block of a common mode coil made of copper wire. Conventionally, a common mode coil with a terminal block has a core case 1 and a terminal block 2 that are integrally molded. When winding, the terminal block 2 becomes an obstacle, and when winding copper wire, There was a problem that the terminal block 2 could not be regenerated because it was sluggish or hit the terminal block 2.

[0003]

[Problems to be solved by the device]

 In order to eliminate these drawbacks, the present invention provides a common mode coil for separating the core case and the terminal block to improve workability and prevent damage to the terminal block.

[0004]

[Means for Solving the Problems]

 The present invention has two protrusions on both sides of the core case of the common mode coil, two protrusions for preventing coil displacement on the lower side, a recess for preventing coil displacement on the bottom of the terminal block, and both side faces. Is a core case and terminal block for a common mode coil characterized by having two hooks with a snap mechanism.

[0005]

[Action]

 As shown in FIG. 1, two protrusions are provided on both sides of the core case of the common mode coil, and a protrusion for preventing coil deviation is provided on the lower side. The bottom of the terminal block will have a recess to prevent the coil from slipping and two hooks with snap mechanisms on both sides. The hooks 10 and 12 of the terminal block 2 lock the two protrusions 5 and 6 of the core case of the common mode coil to prevent the coil from slipping below the core case and the shift prevention protrusion 7 and the terminal block. By fitting the coil misalignment prevention recess 11 on the bottom, it is possible to eliminate the damage of the terminal block that occurs during winding and the difficulty of winding work due to the integrated terminal block. Provide the core case and terminal block of the common mode coil.

FIG. 3 is a perspective view of the terminal block of the present invention. FIG. 4 is a front view of a core case of a conventional common mode coil. In FIG. 4, the core case 1 of the conventional common mode coil and the terminal block 2 are integrally molded. In FIG. 1, two protrusions 5 and 6 are provided on the side surface of the core case 4 of the common mode coil. , The deviation preventing convex portion 7 is provided on the lower side. The terminal block 9 is provided with hooks 10 and 12 each having a snap groove 14 on its side surface, a recess 11 for preventing slippage is provided on the inner bottom of the terminal block 9, and the core case 4 around which the copper wire 8 is wound is placed in the direction of arrow 13. Push into. In FIG. 2, the protrusions 5 and 6 of the core case 4 pushed in the direction of the arrow in FIG. Is fitted into the deviation preventing convex portion 11 of the terminal block 9, and the core case 4 and the terminal block 9 are fixed. In FIG. 3, in order to give the hooks 10 and 12 on both sides of the terminal block 9 snap characteristics, snap grooves 14 are provided on both sides of the hooks 10 and 12.

[0007]

[Effect of device]

 As described above, by retrofitting the terminal block, workability can be improved and defects such as cracks in the terminal block can be prevented.
