Description

Transformer shell

Technical field

The utility model belongs to technical field of electronic components, is related to a kind of transformer shell.

Background technology

Transformer is the electronic component commonly used in electronic circuit board, what it was typically formed by skeleton and by enamel-covered wire coiling Coil forms, and after the completion of coil winding, is typically necessary and sticks insulating tape on the outer surface of coil；However, transformer In practical work process, electric current can be but outer due to coil by the coil of transformer, so as to which coil can be caused to produce heat Portion, which is sticked, insulating tape, therefore the heat in coil is difficult to be scattered and disappeared, and so as to the aging of meeting accelerating coil, and then can damage Transformer, also it can cause fire because of coil short when serious.

Utility model content

In view of the above-mentioned problems, the technical problems to be solved in the utility model be to provide it is a kind of can be by the coil in transformer Cover is set, the transformer shell without the insulating tape that is sticked on the outer surface of coil.

Transformer shell of the present utility model, including frame body, the outer cover of frame body are equipped with shell, and the two of shell The chimb to stretch out is provided with individual lateral wall, raised line, length direction of the raised line along chimb are provided with the lower surface of chimb Extend, the groove for being available for raised line to be embedded in is provided with frame body, several are embedded with along raised line length on the lower surface of raised line The magnet of directional spreding, the bottom of groove are provided with the metallic plate for being available for magnet adsorption, are provided with the side wall of groove and are available for gold The neck that category board enters.

Transformer shell of the present utility model, wherein, leave gap between the madial wall and frame body of shell；So set Put, it is possible to increase the space of inside transformer, improve the radiating effect of coil.

Transformer shell of the present utility model, wherein, wire netting, the madial wall of wire netting are fitted with the madial wall of shell Gap is left between frame body；By the setting of wire netting, can electromagnetic signal caused by shielded coil, avoid coil from producing Raw electromagnetic signal is diffused into outside transformer and the work to other electronic components interferes.

Transformer shell of the present utility model, wherein, the lower surface both sides of raised line, which are provided with, facilitates raised line to be inserted into groove In arc guide surface；In this way, raised line can be facilitated to be inserted into groove, the installation to shell is brought conveniently.

The utility model beneficial effect：The utility model is by the outer cover casing in frame body, two of shell The chimb to stretch out is provided with lateral wall, raised line is provided with the lower surface of chimb, raised line prolongs along the length direction of chimb Stretch, the groove for being available for raised line to be embedded in is provided with frame body, several are embedded with along raised line length side on the lower surface of raised line To the magnet of distribution, the bottom of groove is provided with the metallic plate for being available for magnet adsorption, is provided with the side wall of groove and is available for metal The neck that board enters, by the setting of said structure, shell can set the coil housing in frame body, so as in transformation In the production process of device, the radiating effect of coil can be improved without the insulating tape that is sticked in the outside of coil, one, slows down line The aging of circle, the service life of transformer is improved, two bring conveniently come the production then to transformer.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

As Figure 1-3, transformer shell of the present utility model, including frame body 1, the outside suit of frame body 1 There is shell 2, the chimb 21 to stretch out is provided with two lateral walls of shell 2, raised line is provided with the lower surface of chimb 21 22, length direction of the raised line 22 along chimb 21 extends, and the groove 11 for being available for raised line 22 to be embedded in, raised line are provided with frame body 1 Several magnet 3 being distributed along the length direction of raised line 22 are embedded with 22 lower surface, the bottom of groove 11, which is provided with, is available for magnetic The metallic plate 4 that iron 3 adsorbs, the neck 12 for being available for metallic plate 4 to be caught in is provided with the side wall of groove 11.

Gap is left between the madial wall and frame body 1 of shell 2；In this way, the sky of inside transformer can be improved Between, improve the radiating effect of coil.

Wire netting 5 is fitted with the madial wall of shell 2, gap is left between the madial wall and frame body 1 of wire netting 5； By the setting of wire netting, can electromagnetic signal caused by shielded coil, avoid electromagnetic signal caused by coil from being diffused into transformation Outside device and the work to other electronic components interferes.

The lower surface both sides of raised line 22 are provided with the arc guide surface 23 for facilitating raised line 22 to be inserted into groove 11；So set Put, raised line can be facilitated to be inserted into groove, the installation to shell is brought conveniently.
