Abstract
EE33 embedment transformer including skeleton, coil winding, blade of silicon steel group and shell, is equipped with the cold L needle of inserting on the side of skeleton, the enameled wire winding cold insert the L needle on, the primary input end that the framework top both sides were equipped with the transformer runs through the window of whole skeleton with secondary output end, blade of silicon steel group, packs epoxy resin sealing between coil winding and shell, it forms to weld forms to inserting by a plurality of E shape blade of silicon steel in blade of silicon steel group. The utility model discloses a blade of silicon steel jettisoning traditional EI fold the mode of inserting in turn, adopt the mode of EE piece to inserting, increased the winding space of skeleton, and the EE blade of silicon steel adopts the preparation of advance welding process, guaranteed the stability and the uniformity of product, improved the utilization ratio of the blade of silicon steel, can satisfy and serve the customer to highly requirement good more low more to can provide more optimization spaces in the design of PCB board for the customer.
Description
Technical field
The utility model relates to a kind of miniature transformer, is specifically related to a kind of EE33 potted transformer.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, potted transformer is a kind of miniature transformer, be widely used in the industries such as household electrical appliance, military project communication, instrument and meter, Medical Instruments, electromechanical equipment, its main member comprises skeleton, coil windings, silicon steel sheet and shell, current silicon steel sheet is all adopt EI structure alternately folded mode of inserting, the winding space of this structural framework is less, and structural stability is poor, multi-disc is alternately folded inserts rear easily product noise, vibration, affects the use of product.
Utility model content
The utility model provides a kind of EE33 potted transformer, with solve prior art exist backbone winding space of lines less, volume height is high and structural stability, consistency difference problem.
The utility model comprises skeleton, coil windings, silicon steel sheet group and shell, the side of skeleton is provided with cold slotting L pin, enamelled wire is wrapped on cold slotting L pin, both sides, skeleton top are provided with primary input terminal and the secondary output end of transformer, silicon steel sheet group runs through the window of whole skeleton, filling epoxy resin sealing between coil windings and shell, solving the technical scheme that its technical problem adopts is that silicon steel sheet group is made up of inserting to be welded some E shape silicon steel sheets.
Above-mentioned shell side arranges a reinforcement installing hole.
The EI alternately folded mode of inserting that silicon steel sheet jettisoning of the present utility model is traditional, adopt EE sheet to the mode of inserting, increase the winding space of skeleton, and EE silicon steel sheet adopts advanced welding procedure to make, ensure that stability and the consistency of product, improve the utilance of silicon steel sheet, services client can be met to highly more low better requirement, thus can provide more optimize space in pcb board design for client.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the decomposing schematic representation of the utility model skeleton and silicon steel sheet.
1 shell, 2 skeletons, 3 cold slotting L pins, 4E shape silicon steel sheet, 5 epoxy resin, 6 reinforcement installing holes in figure.
Embodiment
As depicted in figs. 1 and 2, a kind of EE33 potted transformer, comprise skeleton 2, coil windings, silicon steel sheet group and shell 1, the side of skeleton 1 is provided with cold slotting L pin 3, enamelled wire is wrapped on cold slotting L pin 3, both sides, skeleton 2 top are provided with primary input terminal and the secondary output end of transformer, silicon steel sheet group runs through the window of whole skeleton, between coil windings and shell, filling epoxy resin 5 seals, silicon steel sheet group is made up of inserting to be welded some E shape silicon steel sheets 4, and shell 1 side arranges a reinforcement installing hole 6.
The EI alternately folded mode of inserting that silicon steel sheet jettisoning of the present utility model is traditional, adopt EE sheet to the mode of inserting, increase the winding space of skeleton, and EE silicon steel sheet adopts advanced welding procedure to make, ensure that stability and the consistency of product, improve the utilance of silicon steel sheet, services client can be met to highly more low better requirement, thus can provide more optimize space in pcb board design for client.
