Abstract
Small transformer, it relates to electron device technical field, and it contains heat dissipation frame, skeleton, coil, magnetic core, pin, pin groove, insulating layer, the skeleton is the E shape, and the skeleton center transversely is equipped with cylindrical groove, and the magnetic core is inserted and is established at cylindrical inslot, and the coil twines on the skeleton, and heat dissipation frame suit is in the outside of skeleton, the upper surface left and right sides of skeleton is equipped with several pin groove, and the pin groove comprises two hollow circular cylinder concatenations, and pin groove and skeleton fixed connection are equipped with the insulating layer between pin groove and the skeleton, and the pin groove is connected with the lead wire electricity of coil respectively, and vertical the inserting of pin is established at the pin inslot. The difficulty that traditional transformer fixed connection mode is difficult to the dismantlement has been overcome to its pin and skeleton, changes to pin groove fixed connection skeleton instead, and the shell fragment eye -splice of pin area makes the dismantlement of transformer can not damage the skeleton in the design of pin inslot, has prolonged the life -span of transformer.
Description
Technical field
The utility model relates to technical field of electronic devices, is specifically related to a kind of miniature transformer.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil, skeleton and magnetic core.Transformer has large-scale with small-sized, and what have plug-in unit also has paster, and usually, small-sized plug-in unit transformer is often plugged on circuit board and uses.
After the small-sized plug-in unit transformer of prior art is plugged into circuit board, because the number of pins of transformer is more, and pin is directly fixed on plastic insulation skeleton, once need to change, dismantlement work is very difficult, the transformer disassembled, and pin damages due to the time longer plastic skeleton of its periphery that causes scalded by electric iron, pin loosens to some extent or drops, then transformer often also damages and scraps, and has shortened the life-span of transformer, has caused the waste of electronic device.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, the miniature transformer that a kind of structure is simple, reasonable in design, easy to use is provided, its pin and skeleton overcome traditional transformer and are fixedly connected with the difficulty that mode is difficult to dismantle, use pin groove instead and be fixedly connected with skeleton, and strip pins sheet insertion is buckled in the design in pin groove, make the dismounting of transformer damage skeleton, extend the life-span of transformer.
For achieving the above object, the technical solution adopted in the utility model is: it comprises heat-dissipating frame, skeleton, coil, magnetic core, pin, pin groove, thermal insulation layer; Described skeleton is E shape, and frame center is laterally provided with cylindrical groove, and magnetic core is plugged in cylindrical groove, and coil winding is on skeleton, and heat-dissipating frame is sleeved on the outside of skeleton; The upper surface left and right sides of described skeleton is provided with several pin groove, pin groove is spliced to form by two hollow circular cylinders, and pin groove is fixedly connected with skeleton, is provided with thermal insulation layer between pin groove and skeleton, pin groove is electrically connected with the lead-in wire of coil respectively, and pin is vertically plugged in pin groove.
Two sides, described pin bottom are provided with shell fragment, and shell fragment is tiltedly located at pin bottom, is fixedly connected with pin.
Described pin groove, pin and shell fragment are formed by conductive copper.
After adopting said structure, the utility model beneficial effect is: its pin and skeleton overcome traditional transformer and be fixedly connected with the difficulty that mode is difficult to dismantle, use pin groove instead and be fixedly connected with skeleton, and strip pins sheet insertion is buckled in the design in pin groove, make the dismounting of transformer damage skeleton, extend the life-span of transformer.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, the technical solution adopted in the utility model is: it comprises heat-dissipating frame 1, skeleton 2, coil 3, magnetic core 4, pin 5, pin groove 6, thermal insulation layer 7; Described skeleton 2 is E shape structure, and skeleton 2 central cross is provided with cylindrical groove 2-1, and magnetic core 4 is plugged in cylindrical groove 2-1, and coil 3 is wrapped on skeleton 2, and heat-dissipating frame 1 is sleeved on the outside of skeleton 2; The upper surface left and right sides of described skeleton 2 is provided with several pin groove 6, pin groove 6 is spliced to form by two hollow circular cylinders, pin groove 6 is fixedly connected with skeleton 2, thermal insulation layer 7 is provided with between pin groove and skeleton, pin groove 6 is electrically connected with the lead-in wire of coil 3 respectively, and pin 5 is vertically plugged in pin groove 6.
Two sides, described pin 5 bottom are provided with shell fragment 5-1, and shell fragment 5-1 is tiltedly located at pin 5 bottom, is fixedly connected with pin 5.
Described pin groove 6, pin 5 and shell fragment 5-1 are formed by conductive copper.
The lower cylindrical body diameter of described pin groove 6 is larger than upper cylindrical body diameter.
After adopting said structure, the utility model beneficial effect is: its pin and skeleton overcome traditional transformer and be fixedly connected with the difficulty that mode is difficult to dismantle, use pin groove instead and be fixedly connected with skeleton, and strip pins sheet insertion is buckled in the design in pin groove, make the dismounting of transformer damage skeleton, extend the life-span of transformer.
The above, only unrestricted for illustration of the technical solution of the utility model, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
