Description

SMD common mode inductor

Technical Field

The utility model relates to an electronic components technical field specifically is a SMD common mode inductance.

Background

The common mode inductor is also called as a common mode choke coil and is commonly used for filtering common mode electromagnetic interference signals in a switching power supply of a computer, in the design of a board card, the common mode inductor is installed on the board card to play a role in electromagnetic interference filtering, the common mode inductor can effectively inhibit electromagnetic waves generated by a high-speed signal line from radiating and emitting outwards, the common mode inductor is widely used in various electronic fields, when the existing common mode inductor is used, most common mode inductors are connected and used in a pin inserting mode, further, the needed installation space is large, and the common mode inductor cannot well meet the development trend of light and thin of the whole machine.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a SMD common mode inductance to current common mode inductance who proposes in solving above-mentioned background art is when using, and the majority adopts the mode of contact pin to connect the use, and then the installation space that needs is great, the problem that accords with the frivolous development trend of complete machine that can not be fine.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a SMD common mode inductance, includes the mount, the equal fixed mounting in mount bottom surface four corners department has the paster, fixedly connected with ferrite core between the mount middle part, the mount front side has cup jointed the connecting block.

Preferably, the fixing frame comprises two symmetrically arranged connecting frames, and a roller is connected between the middle parts of the connecting frames.

Preferably, the ferrite core comprises a metal coil wound on a fixed frame, the metal coil is processed in a metallization mode, and the metal coil is designed to be a closed magnetic circuit.

Preferably, a 0.4 mm thick adhesive tape is bonded to the front side of the fixing frame.

Preferably, the patch is of an accordion-like structure.

Compared with the prior art, the beneficial effects of the utility model are that:

1. compared with the prior contact pin installation mode, the utility model adopts the patch connection mode, can effectively reduce the height of contact pin products, and further can better meet the structural requirement of the whole machine, so that the device has smaller volume;

2. the ferrite magnetic core has excellent impact resistance and damage-free durability through metallization on the ferrite magnetic core, and meanwhile, the ferrite magnetic core is combined with a closed magnetic circuit design, so that magnetic leakage and electromagnetic interference can be effectively reduced in the using process, and meanwhile, an iron-based metal material is adopted as the material of the magnetic core, so that large saturation current can be provided.

Fig. 1 is a schematic view of the overall structure of the present invention.

The reference numbers in the figures illustrate: 1. a fixed mount; 2. pasting a piece; 3. a ferrite core; 4. and (4) connecting the blocks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides an embodiment:

the utility model provides a SMD common mode inductance, includes

mount

1, and 1 bottom surface four corners department of mount has equal fixed mounting to have paster 2, fixedly connected with ferrite core 3 between 1 middle part of mount, and 1 front side of mount has cup jointed connecting block 4.

Further, mount 1 includes the link that two symmetries set up, be connected with the cylinder between the link middle part, mount 1's special construction through the setting, can conveniently install the magnetic core, combine the connecting block 4 that sets up simultaneously, can conveniently change the ferrite core 3 of placing between mount 1 middle part, it is worth explaining, the connected mode between the cylinder that sets up and mount 1 can adopt the mode of pegging graft to install, also can be through fixed connected modes such as screw, only need guarantee when the connecting block 4 who will set up after dismantling, can conveniently change ferrite core 3.

Further, ferrite core 3 is including the metal coil of coiling on mount 1, and metal coil adopts the mode of metallization to process, and metal coil adopts closed magnetic circuit design, and through the metallization of setting up on with ferrite core 3 make it have excellent shock resistance and not damaged durability, combines the closed magnetic circuit design that sets up simultaneously, can effectual reduction magnetic leakage and electromagnetic interference in the use, adopts iron-based metal material as the material of magnetic core simultaneously, can provide big saturation current.

Further, a 0.4 mm thick adhesive tape is bonded to the front side of the fixing frame 1, and the fixing frame 1 and the connecting block 4 can be conveniently detached through the adhesive tape bonded to the front side of the fixing frame 1.

Further, paster 2 is the ruggedized form structure, at first changes traditional contact pin structure into paster 2's mode, can the effectual height that reduces the product to this can be better satisfy the slim and handy structural requirement of complete machine.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
