Embodiment 1

[0032] Example one, such as Figure 1 to Figure 3 As shown, a magnetic module structure includes a plastic box 1 and a magnetic coil 2. The plastic box 1 is formed with a containing cavity 11 inside. The magnetic coil 2 is embedded in the containing cavity 11 of the plastic box 1. The magnetic coil 2 includes a magnetic ring 21 and an enameled wire 22 wound around the magnetic ring 21. The magnetic coil 2 is fixed to the bottom surface of the accommodating cavity 11 by glue or tape. The enameled wire 22 of the magnetic coil 2 has a head lead 221 and a tail 端lead 222.

[0033] Further, the plastic box 1 is provided with a first fixed side plate 12 corresponding to the head end lead 221, a second fixed side plate 13 corresponding to the tail end lead 222, the first fixed side plate 12 and the second fixed side plate The upper surface of 13 is respectively provided with a lead card slot 14 which completely penetrates in the transverse direction. The first fixed side plate 12 and the...

Embodiment 2

[0042] The second embodiment, a method for assembling a magnetic module structure, includes the following process steps, specifically:

[0043] a. Place the magnetic coil 2 in the accommodating cavity 11 of the plastic box 1, and stick the magnetic coil 2 to the bottom surface of the accommodating cavity 11 by glue or tape;

[0044] b. Align the head lead 221 with the lead card slot 14 of the first fixed side plate 12 and insert the head lead 221 into the lead card slot 14, while aligning the tail lead 222 with the second fixed side plate 13 The lead card slot 14 and the tail lead 222 is embedded in the lead card slot 14;

[0045] c. Pass the metal crimping pin 3 through the terminal through hole 41 of the electrical connection terminal 4 and insert it into the fixing hole 15. The head lead 221 and the tail lead 222 are respectively pressed in along the corresponding metal crimping pin 3 Into the fixing hole 15, the coil lead, the metal crimping pin 3, and the electrical connection ...

Abstract

The invention discloses a novel magnetic module structure and an assembling method therefor. The novel magnetic module structure comprises a plastic box and a magnetic coil, wherein the magnetic coil is embedded in an accommodation cavity of the plastic box and comprises a magnetic ring and a enameled wire; a head lead and a tail lead extend out of the enameled wire; the plastic box is provided with first and second fixing side plates; lead clamping grooves are formed in the upper surfaces of the first fixing side plate and the second fixing side plate respectively; the first fixing side plate and the second fixing side plate are provided with upwards open fixing holes corresponding to the lead clamping grooves respectively; the head lead is embedded and clamped in the lead clamping groove of the first fixing side plate; the tail lead is embedded and clamped in the lead clamping groove of the second fixing side plate; the fixing holes are equipped with metal crimping pins respectively; and the metal crimping pins press the head lead and the tail lead into the corresponding fixing holes. The novel magnetic module structure is novel in design, convenient in assembling, simple in manufacturing process, high in reliability and high in production efficiency. An assembling mode replaces a conventional pin winding and spot welding connection mode in a crimping manner, and the process is simple, convenient and high in reliability.

Description

Technical field [0001] The invention relates to the technical field of magnetic modules, in particular to an improved magnetic module structure and an assembly method thereof. Background technique [0002] For the coil module, it generally includes a plastic box and a magnetic coil installed in the plastic box. The head and tail leads of the magnetic coil are generally connected to the corresponding electrical terminals by means of a winding connection or a spot welding connection. [0003] Among them, as far as the foot-wound connection is concerned, it is to wind certain head and tail leads of the enameled wire on the magnetic coil on the plastic box to block you, and make half, one or more turns; For electrical connection, the head and tail leads can be used to remove the paint before winding, such as tinning, laser etching, etc. After winding, you can also add tin and other materials to enhance the electrical connection, or do not remove the paint before adding tin and other ma...
