Abstract

The utility model relates to the technical field of electronic products, especially a transformer. The transfer comprises a basal body provided with a cavity in which an electromagnetic coil is arranged. The opening of the cavity of the basal body is provided with a cover body that is fastened with the basal body. With the technical scheme, the utility model makes the cover body cover the basal body by a fastening mode, and makes the electromagnetic coil closed in the basal body, so that the external substances are unable to contact the electromagnetic coil, which ensures the stabilization of products. In addition, the utility model has the advantages of simple operation, and does not pollute environment. After the electromagnetic coil is installed, the cover body only needs to be fastened on the basal body.

Description

A kind of transformer

Technical field:

The utility model relates to technical field of electronic products, refers in particular to a kind of transformer.

Background technology:

Usually can need to use transformer in electronic circuit, it mainly is made of some solenoids.During use the current input terminal in the solenoid, output are distinguished in the line attachment.Produce short circuit for fear of coil and other electronic components, solenoid can be placed in the matrix usually, be connected in the circuit by leg.Though this mode improves the stable of product to a certain extent, but because matrix has an opening, impurity or other materials may produce short circuit with the coil in the transformer, in order to overcome this problem, a kind of mode that adopts is a perfusion resin at present, promptly perfusion resin in matrix with the solenoid parcel, cuts off itself and extraneous contacting.Though this mode effect is preferable, its complicated operation, and the smell that produces during perfusion resin can produce certain injury to the operator, do not meet environmental requirement.

The utility model content:

Technical problem to be solved in the utility model just is to overcome existing deficiency in the present product, and a kind of transformer of simple in structure, safe and composite environmental-friendly requirement is provided.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this transformer comprises a matrix that is formed with cavity, in cavity, be provided with solenoid, be provided with a lid in the cavity hatch place of matrix, and lid be connected with substrate.

A lid is set on the matrix of the utility model transformer, and cover cap is located on the matrix, solenoid is closed in the matrix, external substance can't be contacted with solenoid, guaranteed the stable of product by the buckle mode.In addition, the utility model is simple to operate, can not produce environmental pollution, after installing solenoid, only needs the lid clinching is got final product on matrix.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is a three-dimensional exploded view of the present utility model.

Embodiment:

See accompanying

drawing

1,2, the utility model comprises: matrix 1, be arranged at solenoid 2 and lid 3 in the matrix 1.Wherein, matrix 1 is formed with a cavity 11, and solenoid 2 is arranged in the cavity 11.Lid 3 is covered on the opening part of cavity 11, and lid 3 is connected with matrix 1 buckle.Its concrete structure is: lid 3 has extended to form block tongue 31 and guide pillar 32 downwards; Corresponding block tongue 31 offers draw-in groove 12 and through hole 13 with the position of guide pillar 32 on the matrix 1.Be provided with four block tongues 31 in the present embodiment altogether, it on average is arranged at the both sides of lid 3, is formed with lug boss 311 in the end of block tongue 31; Two guide pillars 32 are arranged at the other both sides of lid 3.Also be formed with lug boss 121 in the draw-in groove 12 of matrix 1, block tongue 31 inserts draw-in groove 12 from top to bottom, and after the lug boss on the block tongue 31 311 was crossed lug boss 121 on the draw-in groove 12, lid 3 and matrix 1 were connected with lug boss 311,121 interlaced buckles of realizing on the draw-in groove 12 by block tongue 31.Certainly, this is a kind of embodiment of the present utility model, and position, the quantity of block tongue 31 and draw-in groove 12 can change according to different needs.

In sum, the utility model is covered on lid 3 on the matrix 1 by the buckle mode, and solenoid 2 is closed in the matrix 1, and external substance can't contact with solenoid 2 like this, has guaranteed the stable of product.In addition, the utility model is simple to operate, can not produce environmental pollution, after installing solenoid 2, only needs lid 3 clinchings are got final product on matrix 1.
