Abstract
The utility model discloses a coil framework which comprises a wire shaft, a pin, an upper end plate and a lower end plate, wherein an open groove is formed on one side of the upper end plate. According to the utility model, a group of winding coils also can be added under the condition that the pin is used up, and the structure is simple, and coil framework is convenient to manufacture.
Description
Technical field
The utility model relates to a kind of skeleton that is applied to inductance, transformer, is specifically related to a kind of coil rack.
Background technology
At present, general inductive transformer coil rack is to be combined by bobbin, end plate, stitch.Bobbin, end plate adopt insulating material die casting such as bakelite or plastics, for lead is wound in coil the space are provided, and also the iron core for electromagnetic conversion formation path provides fixing and support.The initiating terminal of coil is welded on the stitch of conduction with terminal, constitutes functional circuit through stitch connection PCB plate.The coil of a transformer has one group at least, has many groups, and one group of coil need take two stitch, and coil quantity is many more, and the stitch that need take is more.Sometimes the stitch quantity that needs can exceed whole stitch quantity of coil rack; Like this designer tend to run into need to increase by one group of coil because there not being enough stitch the transformer framework of having to select for use again, even can not find skeleton and the worry of so many stitch.
Summary of the invention
The utility model technical problem to be solved provides a kind of coil rack, can also increase by one group of winding coil again using under the situation of stitch, and is simple in structure, easy to make.
The technical scheme that the utility model technical solution problem is adopted is: a kind of coil rack, comprise bobbin, stitch, upper head plate, bottom plate, and be provided with open slot in described upper head plate one side.
The open slot of the utility model can or be four for two, and its width, the degree of depth all hold the cooperation of diameter wire size to be advisable with winding the whole story.
The beneficial effect of the utility model is: be provided with open slot in skeleton upper head plate one side; When needs increase by one group of winding coil and do not have stitch to utilize; Just, be directly connected to pcb board, no longer carry out the transition to pcb board through stitch with holding the whole story of this winding lead to draw from two open slots.In like manner, when increasing by two groups of winding coils like need, four open slots then capable of using.This just under the condition that does not change original skeleton pin structure, increases by one group of (or two groups) winding coil easily, realizes the circuit function of expansion.Simple in structure, easy to make.
Description of drawings
