Abstract
The utility model provides a novel dual-mold magnetic core which comprises a rectangular magnetic core body. Inwards-concave core cavities are arranged on the two sides of a magnetic core body respectively, a center column for winding a coil is arranged at the center of each core cavity and is consistent with the end face of the magnetic core body in height, two sets of lead grooves communicated with corresponding core cavities are formed in the two ends of the magnetic core body respectively, and electrodes used for welding circuit boards are arranged on the magnetic core body and located on the outer sides of the lead grooves. According to the novel dual-mold magnetic core, automatic production is achieved, the magnetic core production process can be simplified, and in the magnetic core manufacturing process, a forming machine is directly used for one-time forming, and a slotting process is omitted; production cost is lowered.
Description
Technical field
The utility model relates to the field of inductance element, especially a kind of novel bimodulus magnetic core of one of the making that can be used for paster power inductance.
Background technology
Current paster power inductance is general to be adopted enamel covered wire around the mode on the magnetic core of I shape, and this mode requires there is storage wire casing on magnetic core, so magnetic core generally need have grooving operation, can increase like this 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., for common mode inductance, be particularly to adopt the two-way coiling of toroidal core at present, middle spaced apart with PC plate, form two groups of inductance.This mode is easily breakdown, and useful life is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, novel bimodulus magnetic core that can greatly reduce production costs, increase the benefit is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of novel bimodulus magnetic core, it includes rectangular magnetic core array, the core chamber of an indent is respectively established in magnetic core array main body both sides, center, core chamber is provided with the newel that the around the home coil consistent with main body end face height used, one group of wire lead slot being communicated with respective core chamber is respectively established at magnetic core array main body two ends, and the magnetic core array in wire lead slot outside is provided with the electrode for soldered circuit board.
The shape of cross section of described magnetic core array is circular or has the circle of trimming.
The shape of cross section of described magnetic core array is polygon or the polygon with corner cut.
The shape of cross section of described newel is circular or oval.
Described corner, core chamber all adopts arc-shaped transition.
The utility model adopts the magnetic core of this kind of design to realize automated production, can simplify core production technique, in magnetic core manufacture process, directly goes out with forming machine one-shot forming, has saved grooving operation; While manufacturing inductance, available auto spring coil machine processes coil automatically simultaneously, only coil need be inserted in after magnetic core is fixed and just can carry out product, therefore the inductance element made from this magnetic core can reduce costs greatly, increases the benefit.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1, novel bimodulus magnetic core described in the present embodiment includes rectangular magnetic core array 1, the core chamber 5 of an indent is respectively established in magnetic core array 1 main body both sides, 5 corners, core chamber all adopt arc-shaped transition, 5 centers, core chamber are provided with the newel 2 that the around the home coil consistent with main body end face height used, and the shape of cross section of described newel 2 is circular or oval; One group of wire lead slot 3 being communicated with respective core chamber 5 is respectively established at magnetic core array 1 main body two ends, and the magnetic core array 1 in wire lead slot 3 outsides is provided with the electrode 4 for soldered circuit board.The shape of cross section of described magnetic core array 1 is circular or has circle, the polygon of trimming or have the polygon of corner cut.The magnetic core of this programme has been realized automated production, can simplify core production technique, in magnetic core manufacture process, directly goes out with forming machine one-shot forming, has saved grooving operation; While manufacturing inductance, available auto spring coil machine processes coil automatically simultaneously, only coil need be inserted in after magnetic core is fixed and just can carry out product, therefore the inductance element made from this magnetic core can reduce costs greatly, increases the benefit.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection range of the present utility model.
