Abstract
The utility model relates to a novel magnetic core which comprises a magnetic core body with a cup-shaped structure, wherein a central post used for allowing a coil to be wound is arranged in the central position of the magnetic core body, at least one pair of mutually symmetrical lead wire grooves used for leading out the coil is formed in the bottom edge of the magnetic core body, and electrodes used for welding a circuit board are arranged in the positions, close to the lead wire grooves, of the bottom of the magnetic core body. By adopting the novel magnetic core with the design, a groove cutting procedure is saved, the automatic production is achieved, the cost is greatly reduced during the manufacture of inductive elements, and the benefits are improved.
Description
Technical field
The utility model relates to the field of inductance element, especially a kind of a kind of novel magnetic core that can be used for the making of paster power inductance.
Background technology
Present paster power inductance is general adopts the mode on the magnetic core of I shape with enamel covered wire, and this mode requires that the storage wire casing is arranged on magnetic core, so magnetic core generally need have the grooving operation, dust pollution is arranged when cutting processing, also can increase the magnetic core manufacturing cost; In addition, in inductance manufacturing process, need to clamp magnetic core with coil winding machine and wind the line, concerning the power inductance of thick line, be difficult for realizing automated production.And for the described magnetic core of patent, can overcome above-mentioned two point defects, the inductance element made from this magnetic core can reduce costs greatly, increases the benefit.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, a kind of novel magnetic core is provided, can have simplified core production technique, directly gone out to get final product with the forming machine one-shot forming in the magnetic core manufacture process, saved the grooving operation, prevented the dust pollution that produces when grooving; When making inductance simultaneously, available auto spring coil machine processes coil automatically, only needs coil is inserted in just can carry out product after magnetic core is fixed, therefore the inductance element made from this magnetic core can reduce costs greatly, increases the benefit.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of novel magnetic core, comprise the magnetic core array with cup-like structure, the center of described magnetic core array is provided with for the newel of coil around the home, offer at least one pair of symmetrical wire lead slot that is used for drawing coil on the bottom margin of magnetic core array, close wire lead slot place, magnetic core array bottom is provided with the electrode for soldered circuit board, this magnetic core generally adopts the silver-colored electroplating technology of end, first go up silver on magnetic core, going up nickel plating and zinc-plated formation can be for the firm electrode of welding again, in order to can be welded on circuit board when using.
In order to be convenient to distinguish the direction of magnetic core, the shape of cross section of described magnetic core array is for circle or have the circle of trimming.
In order to be convenient to distinguish the direction of magnetic core, the shape of cross section of described magnetic core array is polygon or polygon with corner cut.
The shape of cross section of described newel is circular or oval.
The beneficial effects of the utility model are: described a kind of novel magnetic core, adopt the magnetic core of this kind design, and saved the grooving operation, there is no dust pollution, realized automated production, and greatly reduced costs when making inductance element, increase the benefit.
