Abstract
The utility model discloses a kind of magnetic core of transformer ground structure of reserved lead, wherein the winding has reserved a magnetic core ground lead, which is wound in a PIN needle, and the upward bending of magnetic core ground lead and is affixed on magnetic core outer wall.First, by having reserved a magnetic core ground lead in winding, the magnetic core ground lead is wound in a PIN needle and bending is affixed on magnetic core outer wall upwards, a magnetic core ground lead is used alone that replace tradition to be connected in PIN needle and magnetic core, the utility model is not necessarily to other wiring, reaches the automated production purpose of magnetic core ground connection process, so that technique production production capacity greatly promotes, cost relative drop further improves transformer production efficiency.And the fixed form of conducting resinl compares tradition using the fixed form of copper foil or adhesive tape, contact is more preferable, the problem of not being afraid of copper foil or falling off for adhesive tape and lead to poor contact.
Description
Technical field
The utility model relates to transformer production field technologies, refer in particular to a kind of magnetic core of transformer ground connection of reserved lead
Structure.
Background technique
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and transformer is extensive in today's society
Use, the corresponding main body of transformer is skeleton, is equipped with magnetic core in skeleton, be wound with shield winding on skeleton, shielding around
Group includes armature winding and secondary windings.Transformer is widely used all trades and professions, so that transformer quantity required is huge,
Manufacturer need to produce the demand that transformer is just able to satisfy society in enormous quantities.
High frequency transformer needs magnetic core to be grounded mostly, inhibits electromagnetic interference as transformer outer shield using magnetic core；
This technique is mostly at present that individually the other end with the one ends wound of a lead in lead in PIN needle sticks on copper foil, then
Copper foil is affixed on magnetic core, this technique there are certain poor contact and the case where performance failure, and can only handwork,
Simultaneously the automated production process of front and back section can therefore and middle disconnection so needing to expend a large amount of manpower working hours seriously affects production
Can, make entire transformer cost is opposite to rise.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of reserve and draws
The magnetic core of transformer ground structure of line, efficiently solves existing magnetic core ground structure there is poor contact and performance is lost
Effect needs to expend a large amount of manpower works and transformer cost with respect to the problem of rising.
To achieve the above object, the utility model is using following technical solution:
A kind of magnetic core of transformer ground structure of reserved lead, includes skeleton, magnetic core and winding；It is arranged on the skeleton
There is PIN needle；The magnetic core is installed on skeleton；The winding is wound on skeleton, it is characterised in that: the winding has reserved a magnetic
Core ground lead, the magnetic core ground lead are wound in a PIN needle, and the upward bending of magnetic core ground lead and are affixed on magnetic core outer wall
On.
As a preferred embodiment, the end of the magnetic core ground lead is fixed on magnetic core outer wall by conducting resinl.
As a preferred embodiment, the electroplating surface of the magnetic core ground lead has tin layers.
As a preferred embodiment, the magnetic core ground lead is affixed on magnetic core outer wall centered position.
As a preferred embodiment, the magnetic core ground lead is formed with dog-ear, magnetic core ground lead in magnetic core corner
Recline two adjoining outer walls of magnetic core simultaneously.
As a preferred embodiment, the magnetic core ground lead bending is L-shaped.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Known to scheme:
One, by having reserved a magnetic core ground lead in winding, the magnetic core ground lead be wound in a PIN needle and to
Upper bending is affixed on magnetic core outer wall, and a magnetic core ground lead is used alone that replace tradition and is connected in PIN needle and magnetic core, this
Utility model is not necessarily to other wiring, reaches the automated production purpose of magnetic core ground connection process, so that technique production production capacity mentions significantly
It rises, cost relative drop further improves transformer production efficiency.
Two, the fixed form of conducting resinl compares tradition using the fixed form of copper foil or adhesive tape, and contact is more preferable, is not afraid of
Copper foil or falling off for adhesive tape and the problem of lead to poor contact.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
The utility model is described in detail.
Detailed description of the invention
Fig. 1 is the main view of the preferred embodiment of the utility model；
Fig. 2 is the side view of the preferred embodiment of the utility model.
Description of drawing identification:
10, skeleton 11, PIN needle
20, magnetic core 30, winding
31, magnetic core ground lead 40, conducting resinl.
Specific embodiment
It please refers to shown in Fig. 1 to Fig. 2, that show the specific structures of the preferred embodiment of the utility model, include
Skeleton 10, magnetic core 20 and winding 30.
PIN needle 11 is provided on the skeleton 10；The magnetic core 20 is installed on skeleton 10；The winding 30 is wound in skeleton 10
On, wherein the winding 30 has reserved a magnetic core ground lead 31, which is wound in a PIN needle 11,
And the upward bending of magnetic core ground lead 31 and be affixed on 20 outer wall of magnetic core, specifically, the end of magnetic core ground lead 31 passes through
Conducting resinl 40 is fixed on 20 outer wall of magnetic core.Traditional magnetic core grounding technology is single use a lead, and lead one end is twined
It is around in PIN needle 11, the other end sticks on a copper foil, then copper foil is affixed on 20 outer wall of magnetic core.And the utility model by around
Group 30 reserves a magnetic core ground lead 31, and it is not necessary that lead is used alone, and the fixed form of conducting resinl 40 is compared using copper foil
Or the fixed form of adhesive tape, contact is more preferable, the problem of not being afraid of copper foil or falling off for adhesive tape and lead to poor contact.
The electroplating surface of the magnetic core ground lead has tin layers, avoids being oxidized.Magnetic core ground lead 31 is affixed on magnetic core 20
Outer wall centered position, and magnetic core ground lead 31 is formed with dog-ear in 20 corner of magnetic core, magnetic core ground lead 31 pastes simultaneously
