た。 [Detailed explanation of the invention] A. Purpose of the invention [Industrial application field] The present invention is a vertically installed type that uses a cylindrical core to suppress electromagnetic noise generated in and propagated to electronic equipment. This article relates to a common mode choke coil with a terminal plate. [Prior Art] As shown in FIGS. 3 and 4, this type of conventional common mode York coil has a core case 31 housing a cylindrical core and a partition plate 8 parallel to the axial direction of the core. The integrally formed vertical core case with a support plate has a partition plate 8 that divides the core into two in the axial direction, and the coil wound on the core case can be divided into two.
The vertical groove 1 is divided into two parts and attached to the top surface of the lid member 12.
Fit the partition plate 8 into the upper partition 14 having 6,
It was a combination. Further, the coil wound on the core case and the terminal plate are integrated, and the end of the winding coming out of the core is inserted into the groove and fixed with adhesive. [Problem that the invention aims to solve] In the process of making the coil to be wound on the core case,
Conventionally, the partition plate and the core case around which the coil was wound were integrated, making it difficult to wind the coil.
Furthermore, the method of inserting the winding ends into the grooves of the partition plate and fixing them with adhesive has the drawbacks that the work is difficult and expensive. B. Structure of the invention [Means for solving the problem] The present invention makes it easier to wind the coil by separating the partition plate and the core case in which the coil is wound, and the core case in which the core is stored. By inserting a pre-installed protrusion with a claw that fits into the groove on the terminal plate into the groove on the terminal plate, the winding end can be held down, making it possible to use a common terminal that is inexpensive and easy to work with. Provide mode coil. That is, in the present invention, a cylindrical core made of a magnetic material with high relative magnetic permeability is housed in a core case body made of an insulating material, a cover plate is covered to form the core case, and two windings are wound in a common mode. A mode coil is formed, a partition plate with claws is fitted into a fitting groove installed in the core case, and the lid plate and the core case body are integrated. On the terminal plate with a groove, the end of the winding of the coil is held down by a convex part with a split groove and a claw in the direction of the terminal plate attached to the lower end surface of the core case.
This is a common mode coil that features an integrated terminal board and core case. [Operation] In this invention, two common mode windings are
The partition plate for separating the coils is prepared separately from the core case, making it easy to wind the coil.
After winding the coils in the core case, insert and fit the partition plate into the fitting groove attached to the core case to electrically insulate the two coils.
4 protrusions with inward facing claws attached and a split groove in the center of the bottom surface of the terminal board.
The end of the winding of the coil passes through the groove of the protrusion and is pulled out below the terminal plate, and is fixed by the end of the terminal plate and the groove of the protrusion. Therefore, a common mode coil can be easily assembled and formed by combining only resin assemblies without using an adhesive. [Example] In FIG. 1, a cylindrical core with high relative magnetic permeability characteristics is housed in a core case body 3a made of an insulating material, and partition plates 8 are provided on the upper and lower surfaces of the core case body 3a and the lid plate 20. A total of four fitting grooves 1 are provided on each end face, two on the top surface and two on the bottom surface, so that the fitting grooves 1 are oriented toward the inside diameter of the case.
Further, at the lower portions of the upper and lower surfaces of the core case body 3a and the lid plate 20, there is a convex portion 6 provided with claws for connecting and fixing the terminal plate 5 and having a groove 11 attached in the center.
They are provided on the upper surface of the core case body and the upper surface of the lid plate 20 at certain intervals. The core case body 3a is covered with a lid plate 20 to form a core case 3 , and a common mode winding is wound around the core case 3 an appropriate number of times to form a common mode coil. The terminal plate 5 is made of an insulating material, and has a winding end of a coil wound around the core case on its longitudinal side, and a claw 7 whose tip faces toward the core case, and is fitted into a convex portion having a split groove 11 at the center of the tip. A groove 9 for mating is provided at the same position as the protrusion 6 of the core case, and four grooves 9 are provided on the end face of the terminal plate. The core case is wound to form a coil, the partition plate 8 is inserted into the core case fitting groove, the core case and the lid plate 20 are fixed by the partition plate claws 10 of the partition plate 8, and the coil winding terminal is fixed. The protrusion 6 is pulled out from the slot 11, the protrusion 6 is inserted into the terminal plate 5, the coil is fixed, and the common mode coil is completed. C. Effects of the invention As explained above, according to the invention, since the terminal board and the coil are independent, the winding work is easier, and the winding end of the coil is held down with a split groove instead of the conventional adhesive. It has become possible to provide a common mode coil that can be fixed to the terminal plate using a convex portion having claws, which is easy to work with and is inexpensive.
