Abstract
The utility model discloses a magnetic core grounding structure of a transformer. The magnetic core grounding structure comprises a framework and a magnetic core and further comprises a magnetic core grounding lead connected to a framework pin. The magnetic core grounding lead is wrapped by adhesive tape and fixed to and abuts against the outer wall of the magnetic core. The magnetic core grounding lead at least abuts against a corner of the magnetic core. In the transformer production process, the magnetic core of the transformer needs to be grounded, and electromagnetic interference is mainly reduced through the process. According to the magnetic core grounding structure of the transformer, the magnetic core grounding lead connected to the framework pin is led out of the framework to abut against the outer wall of the magnetic core, and the magnetic core grounding lead is then turned to make the tail end portion of the lead abut against the corner of the adjacent outer walls of the magnetic core. According to the magnetic core grounding structure, the number of the contact faces between the magnetic core grounding lead and the outer wall of the magnetic core is large, and no poor contact phenomenon can occur after impregnation; due to the structure, production procedures are simple, production materials are fewer, and production efficiency is improved.
Description
Technical field
The utility model relates to transformer production art, refers in particular to a kind of magnetic core of transformer ground structure.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, transformer is widely used at society, and the main body that transformer is corresponding is skeleton, and magnetic core is installed in skeleton, on skeleton, be wound around shielding winding, shielding winding includes armature winding and secondary winding.Transformer is widely used all trades and professions, makes transformer quantity required huge, and manufacturer need produce transformer in enormous quantities could meet social demand.
In producing the process of transformer, magnetic core of transformer needs ground connection, and this technique is mainly to reduce electromagnetic interference (EMI); In prior art, magnetic core of transformer ground connection needs in addition around tinned wire scolding tin, or self-adhesion Copper Foil, then welding.These two kinds of ground structure more complicated, are used material many, and production hour is long, and cost is higher, and production efficiency is low.
Utility model content
The utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of magnetic core of transformer ground structure, solves magnetic core of transformer ground structure complexity and the low problem of production efficiency in prior art.
For achieving the above object, the utility model adopts following technical scheme:
A kind of magnetic core of transformer ground structure, include skeleton and magnetic core, also include the magnetic core ground lead being connected on described skeleton stitch, described magnetic core ground lead is coated and fixed and abuts in the outer wall of described magnetic core by adhesive tape, and described magnetic core ground lead is at least posted by magnetic core one corner.
As a kind of preferred version, described magnetic core ground lead is formed with knuckle in magnetic core corner, the magnetic core ground lead adjacent outer wall of described magnetic core two that simultaneously reclines.
As a kind of preferred version, the length of described magnetic core ground lead knuckle rear section account for correspondence the magnetic core outer wall base length of side 1/3rd to 1/2nd.
As a kind of preferred version, described skeleton includes winding slot and is positioned at the first baffle plate and the second baffle of winding slot both sides, on this first baffle plate, is provided with a plurality of stitch.
As shown from the above technical solution, the utility model compared with prior art, there is following many-sided obvious advantage and beneficial effect: the utility model adopts a kind of new magnetic core of transformer ground structure, the magnetic core ground lead that is connected to skeleton stitch is guided to magnetic core outer wall from skeleton outside and reclines, then magnetic core ground lead again knuckle make lead-in wire cling to the corner of the adjacent outer wall of magnetic core.Magnetic core ground lead and the magnetic core outer wall contact-making surface of this magnetic core of transformer ground structure are many, do not have loose contact phenomenon after impregnation; This structure makes production process simple, produces material few, has improved production efficiency.
For more clearly setting forth architectural feature of the present utility model, technological means and the specific purposes that reach and function, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Accompanying drawing explanation
Fig. 1 is the perspective view of the embodiment of the utility model.
Accompanying drawing identifier declaration:
1, skeleton, 11, stitch, 2, magnetic core, 21, corner, 3, magnetic core ground lead.
Embodiment
Please refer to shown in Fig. 1, it has demonstrated the concrete structure of the embodiment of the utility model: a kind of magnetic core of transformer ground structure, include the skeleton 1 and the magnetic core 2 that fit together, described skeleton 1 includes winding slot and is positioned at the first baffle plate and the second baffle of winding slot both sides, is provided with a plurality of stitch 11 on this first baffle plate.
And, also include the magnetic core ground lead 3 being connected on described skeleton 1 stitch 11, described magnetic core ground lead 3 is coated and fixed and abuts in the outer wall of described magnetic core 2 by adhesive tape, and described magnetic core ground lead 3 is at least posted by magnetic core one corner 21 places, described magnetic core ground lead 3 is formed with knuckle in magnetic core corner 21 places, the described magnetic core ground lead 32 liang of adjacent outer walls of described magnetic core that simultaneously recline.The length of described magnetic core ground lead 3 knuckle rear sections accounts for 1/3rd to 1/2nd of the described magnetic core 2 outer wall base length of sides.
The utility model adopts a kind of new magnetic core of transformer ground structure, the magnetic core ground lead 3 that is connected to skeleton 1 stitch 11 is guided to magnetic core 2 outer walls from skeleton 1 outside and reclines, then magnetic core ground lead 3 again knuckle make lead terminal partly cling to corner 21 places of magnetic core 2 adjacent outer walls.The magnetic core ground lead 3 of this magnetic core of transformer ground structure and magnetic core 2 outer wall contact-making surfaces are many, do not have loose contact phenomenon after impregnation; This structure makes production process simple, produces material few, has improved production efficiency.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
