Example Embodiment

[0021] Example

[0022] Combine Figure 1 to Figure 4 , This embodiment relates to a skeletonless transformer for an automobile charging pile, which includes a magnetic core assembly 1 and a winding coil 2. The magnetic core assembly 1 has a magnetic core shaft with a circular cross section, and the winding coils 2 are uniformly wound on the magnetic core shaft.

[0023] An insulating plate 3 is arranged on the bottom of the magnetic core assembly perpendicular to the magnetic core axis, a layer of insulating tape is arranged between the winding coil 2 and the magnetic core axis, and the leads drawn from the winding coil 2 pass through the insulating plate 3 to form pins 31. The lead wire drawn from the winding coil 2 is covered with a Teflon sleeve to the junction of the lead wire and the insulating plate. The size of the insulating board 3 is 36mm*40mm, and 12 holes are provided on the insulating board 3. The insulating board 3 is an epoxy resin board with a thickness of 0.5-1...

Abstract

The invention discloses a skeletonless transformer for an automobile charging pile, comprising a magnetic core assembly and a winding coil, wherein the magnetic core assembly has a magnetic core shaft; the winding coil is uniformly wound on the magnetic core shaft; the magnetic An insulating plate is arranged on the bottom of the core assembly in a direction perpendicular to the magnetic core axis; the leads drawn from the winding coil pass through the insulating plate to form pins; an insulating tape is arranged between the winding coil and the magnetic core axis, A retaining wall tape is arranged between the upper end plate and the lower end plate; the cross section of the magnetic core shaft is circular. The invention relates to a skeletonless transformer for an automobile charging pile, which adopts a fully enclosed process, the voltage resistance and insulation pass the temperature resistance level of F88 insulation system above 155°C, and a high temperature copper wire of 180°C is used as the raw material of the winding coil. Performance and service life have been greatly improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a frameless transformer for automobile charging piles. Background technique [0002] Conventional transformers are composed of a skeleton, a magnetic core and a coil. In such transformers, the bobbin takes up a lot of space. Due to limited space in DC charging piles, conventional transformers cannot be used in DC charging piles due to volume and cost factors. Contents of the invention [0003] The purpose of the present invention is to provide a frameless transformer for a car charging pile, which can reduce the volume and cost of the transformer. [0004] In order to solve the above-mentioned technical problems, the object of the present invention is achieved as follows: a skeletonless transformer for a car charging pile involved in the present invention includes a magnetic core assembly and a winding coil, and the magnetic core assembly has a magnetic core shaft; The ...
