Description
Technical Field
The invention relates to the technical field of ferrite cores, in particular to a clamp structure for a special-shaped ferrite core.
Background
For this reason, the industry generally focuses on changing the shape, for example, modifying a mold for pressing a C-shaped ferrite core blank, so that the pressed C-shaped ferrite core blank forms a concave platform or a convex platform at the arc top, and the concave platform or the convex platform is used as a positioning reference surface in the grinding process. Still another processing method is: and pre-grinding the arc top of the C-shaped ferrite core to form a positioning reference surface.
Any one of the three methods for acquiring the positioning reference surface has the following technical problems: in the case of the first way, forming a concave platform at the arc apex, the power is directly affected since the cross section of the C-shaped ferrite core is reduced; in the case of the second way, that is, forming a convex platform at the top of the arc, it is difficult to match with the electric product or lighting fixture during use because the volume is enlarged; the third method, in which the positioning reference surface is previously ground at the apex of the arc, is not only disadvantageous in the first method, but also causes a sharp corner at the edge of the reference surface, which causes damage to the coil when the coil is wound.
To solve the above problems, a chinese patent No. 201220127732.3, entitled C-shaped ferrite core processing clamp structure, includes a base, a C-shaped cavity formed on one upward side surface of the base in a use state and penetrating from one end of the base in a length direction to the other end, and hook plate accommodating cavities respectively formed on two end portions of a downward side of the base in a use state, the hook plate accommodating cavities being located at a central position in a width direction of the base; the pressing strip is matched with the C-shaped cavity, and a concave cavity is formed at two ends of the pressing strip; and one end of each clamping foot is matched with the hook plate accommodating cavity, and the other end of each clamping foot is matched with the concave cavity.
Although the technical scheme can ensure the power of the C-shaped ferrite core and the assembly effect when in use, the coil can be prevented from being damaged when the coil is wound. But can only be applicable to the C-shaped ferrite core of single size, can not be applicable to the C-shaped ferrite core of multiple sizes, and the application scope is narrow to be unfavorable for the enterprise to increase the product variety.
