Embodiment Construction

[0026] The invention relates to a transformer skeleton for preventing winding lead wires from crossing and a method for using the same. Figure 1-6 The present invention is described in detail with specific examples. In this specific embodiment, the direction away from the axis of the magnetic core slot is defined as outer.

[0027] The present invention provides a transformer bobbin capable of preventing winding leads from crossing, including a bobbin body 100 and a sheath 200 . The skeleton body 100 includes a top leaf 10, a primary winding post 20, and a bottom leaf 30 connected in sequence from top to bottom. The primary winding post 20 is a hollow cylindrical shape extending longitudinally, and the primary winding post 20 runs through the top leaf 10 and the bottom leaf. 30 and forms a core slot 40 , wherein the outer diameter of the top vane 10 is smaller than the outer diameter of the bottom vane 30 .

[0028] Both sides of the top surface of the top blade 10 are prov...

Abstract

The invention provides a transformer framework for preventing winding lead crossing. A framework body comprises a primary wrapping post, a top blade and a bottom blade, the top blade and the bottom blade are arranged at the top and the bottom of the primary wrapping post, and a magnetic core groove is formed by the center of the primary wrapping post. Magnetic core baffles are arranged on the twosides of the top face of the top blade. A first primary part is arranged on one side of the bottom blade, and a second primary part and a secondary part are arranged on the other side of the bottom blade. Primary wire passing grooves are formed in the side faces, away from the wrapping post, of the first primary part and the second primary part respectively, and the bottom face of the first primary part and the bottom face of the second primary part are connected with primary pins. A sheath is further included, and comprises a hollow cylindrical secondary wrapping post, a top baffle and a bottom baffle, and the top baffle is arranged at the top of the secondary wrapping post, and the bottom baffle is arranged at the bottom of the secondary wrapping post. The outer diameter of the top bladeis smaller than that of the bottom blade. The sheath adaptively sleeves the periphery of the top blade from top to bottom, and the sheath is in adaptive clamped connection with the framework body. Space isolation of a secondary coil, a primary coil and a primary lead is achieved. According to the transformer framework, automation of the wire wrapping procedure of the secondary coil is achieved, and the product quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to a transformer for a charger, in particular to a transformer frame for preventing winding leads from crossing and a method for using the same. Background technique [0002] The transformer is an important electrical device in the power output distribution system. It mainly includes a magnetic core, a transformer skeleton, a primary coil and a secondary coil, and uses the principle of electromagnetic induction to transmit electric energy. The primary coil is used to connect with the AC power supply and is wound on the winding post of the transformer skeleton. The secondary coil is used to output the induced potential and is wound outside the primary coil. By setting multiple coil windings on the secondary coil, the output potential can be changed. potential level. However, the primary lead wire 301 of the primary coil 300 crosses the secondary coil 400 at 45° or 90°, such as Figure 7 As shown, and can produce tensile force, it ...
