Description

Technical Field

[0001] The utility model relates to the technical field of common mode inductors, in particular to a common mode inductor with a new assembly structure. Background Technique

[0002] At present, most traditional common mode inductors adopt bases with PINs or closed perforated bases;

[0003] 1. When installing a base with PINs, the base manufacturer needs to implant PINs, and during assembly, the leads need to be wound around the PINs, resulting in a significant increase in manufacturing costs;

[0004] 2. The perforated base cannot implement an integrated positioning auxiliary structure. Usually, no positioning structure is added, or a positioning structure is added separately, or glue is added for fixation. The installation is prone to tilting and is not suitable for automated production. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a common mode inductor with a new assembly structure, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A common mode inductor with a new assembly structure includes a base body. A magnetic core is vertically fixed inside the base body. A coil is wound around the outside of the magnetic core. Several "C"-shaped positioning holes are reserved at the bottom end of the base body, and a positioning plate is connected to the middle of the base body. The coil has several leads, and the leads are led out from the bottom end of the base body through the positioning holes.

[0007] Further, a positioning groove is reserved at the bottom of the base body, and the magnetic core is fixed inside the positioning groove.

[0008] Further, the base body is made of an insulating material, and the positioning plate is arranged between two coils.

[0009] Further, after the bottom end of the lead extends out from the inside of the positioning hole, a bending part is provided.

[0010] Further, a limiting notch is reserved at the top of the base body, and the lead can extend to the back of the base body through the limiting notch.

[0011] Further, wire grooves are symmetrically arranged on the back of the base body, and the leads are located inside the wire grooves.

[0012] Further, several reserved grooves are reserved at the bottom end of the base body, and the reserved grooves are communicated with the positioning holes. The arrangement of the reserved grooves forms a "king" - shaped reinforcing rib structure at the bottom of the base body.

[0013] The utility model provides a common mode inductor with a novel assembly structure. Compared with the prior art, it has the following beneficial effects:

[0014] The common-mode inductor with this new assembly structure adopts a PIN-free card slot-type integrated auxiliary positioning structure at the base. It is easy to install and can realize automated production without the need for glue dispensing. It can scientifically and effectively prevent assembly tilt and reduce manufacturing costs.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides a technical solution: a common-mode inductor with a novel assembly structure, which is composed of a seat body 1, a magnetic core 2 and two coils 3, wherein a positioning groove 13 is reserved at the bottom of the seat body 1, the magnetic core 2 is fixed inside the positioning groove 13, and the two coils 3 are respectively wound on both sides of the magnetic core 2. The entire seat body 1 is made of insulating material, and a positioning plate 12 is connected to the middle of the seat body 1, and the positioning plate 12 is arranged between the two coils 3. The positioning plate 12 and the positioning groove 13 can prevent the entire common-mode inductor from tilting during assembly;

[0024] In addition, a number of "C"-shaped positioning holes 11 are reserved and provided at the bottom end of the seat body 1. The coil 3 has a number of pins 31. The pins 31 are led out from the bottom end of the seat body 1 through the positioning holes 11.

The bending portion 32 can strengthen the strength of the pin 31 and enhance the fixation. A limiting notch 14 is reserved and provided at the top of the seat body 1. The pin 31 can extend to the back of the seat body 1 through the limiting notch 14. Wire grooves 15 are symmetrically provided on the back of the seat body 1. The limiting notch 14 communicates with the wire grooves 15. The pin 31 is located inside the wire grooves 15. A number of reserved grooves 16 are reserved and provided at the bottom end of the seat body 1. The reserved grooves 16 communicate with the positioning holes 11. The provision of the reserved grooves 16 forms a "king"-shaped reinforcing rib structure at the bottom of the seat body 1, greatly strengthening the structure of the entire seat body 1.
