Abstract

The utility model relates to a framework of a shielding box, which comprises two identical framework components; wherein, the framework components are a C-shaped integral metal profile structure enclosed by three faces; a concave groove is arranged on the end face of one profile plate of the opening end; a convex wedge corresponding to the concave groove is arranged on the end face of the other profile plate; the two framework are clipped with the convex wedge through the concave groove to form a framework body of the shielding box; the convex wedge is the structure with big head and small tail; the concave groove is a corresponding structure with a big intra-cavity and a small mouth; cover-plate fixing holes are arranged on each of the profile plates of the framework body components. When in use, the cover plate can be fixed on the holes through screws to form a closed shielding box body. The concave-convex structure of the two framework components made by the same die by the utility model can be clipped with each other, so the shielding box framework with the advantages of good shielding effect, simple producing and convenient using can be assembled.

Description

The shielding box framework

Technical field

The utility model relates to the electronic product shield technology, more particularly, relates to a kind of multiduty shielding box framework.

Background technology

At present, the shielding box that is used for shield electromagnetic in electronic product roughly has following three kinds:

First kind, form with the sheet iron bending, this structural cooling performance is poor, and the easy oxidation of electrodeposited coating comes off, and part is easy deformation also, generally can only be used for requirement shielding and the product that do not need to dispel the heat;

Second kind, process with four thick aluminium sheets, the processing of this structure is loaded down with trivial details, and is insecure and globality is poor, so less employing;

The third processes the monoblock aluminium ingot with milling machine, the shielding box good integrity of this structure, and the shield effectiveness ideal, and can change flexibly according to the needs of size; But its defective is that machining time is long, and cost is expensive, also will waste a large amount of aluminiums, therefore seldom uses when product lot quantity is big.

As seen, all there is such-and-such problem in existing these shielding box frameworks.

The utility model content

The technical problems to be solved in the utility model is, at the above-mentioned defective of existing shielding box framework, provides the novel shielding box framework that a kind of shield effectiveness is good, processing is simple, easy to use.

The technical solution of the utility model is, constructs a kind of shielding box framework, it is characterized in that, comprises two identical frame assemblies, and described frame assembly is surrounded by three faces The end face that shape bulk metal profile structure, the end face of a profile plate of its openend are provided with groove, another profile plate is provided with the protruding wedge corresponding with described groove, and two frame assemblies fasten mutually by described groove and protruding wedge, form described shielding box framework.

In shielding box framework described in the utility model, described protruding wedge is the structure that head is big, afterbody is little, and described groove is corresponding big, the oral area minor structure of inner chamber.Each profile plate of described frame assembly is provided with the fixing hole that is used for fixing upper and lower cover plate.

In shielding box framework described in the utility model, described frame assembly is the aluminium section bar frame assembly by a die drawn moulding.The surface of described frame assembly is provided with and handles the flower-pattern layer that forms through sandblast or wire drawing and through electric conductive oxidation.

The utility model fastens mutually by the concaveconvex structure of two frame assemblies that same mould is made, and can assemble to obtain a shielding box framework that shield effectiveness is good, processing is simple, easy to use.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is the stereogram of a frame assembly of the utility model shielding box framework;

Fig. 2 is the vertical view of frame assembly shown in Fig. 1;

Fig. 3 is the schematic diagram when being buckled into a shielding box framework with two frame assemblies;

Fig. 4 is the explosive view when assembling shielding box with frame assembly of the present utility model.

Embodiment

A preferred embodiment of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 3.As can be seen from Figure 1, the frame assembly in the present embodiment is surrounded by three faces

The whole aluminium section bar structure of shape, can be with a die drawn moulding during manufacturing, the end face that the end face of a profile plate of its openend is provided with groove 5, another profile plate is provided with the protruding wedge 4 corresponding with groove 5, the cylinder of its convexity wedge 4 for stretching out from end face, the connecting portion of it and end face is less than the diameter of extension cylinder, and just head is big and afterbody is little; Correspondingly, groove 5 circular hole for caving in, its inner chamber is big and oral area is little.

Get two frame assemblies, with the protruding wedge of another assembly of groove alignment of an assembly, its protruding wedge is aimed at the groove of another assembly simultaneously, buckles into vertically downward, can obtain shielding box framework shown in Figure 3.As can be seen from Figure 2, in the design of the left side of frame assembly decorative pattern 2 is arranged, its surface is also handled, is handled through electric conductive oxidation through sandblast or wire drawing.On profile plate, also be provided with five cover plate fixing holes 3, can upper and lower cover plate 7,8 be fixed in these holes with screw during use, as shown in Figure 4, form the shielding box body of a sealing.

In the utility model with same Mold Making frame assembly, with the concavo-convex knot of two frame assemblies Structure fastens mutually, can obtain a complete shielding box framework, has the following advantages: simple in structure, Easily processing; Only need a simple mould, greatly reduce die manufacturing cost; Two frameworks Assembly closely fastens, and refills to prepare after the upper and lower cover plate, consists of the box body of sealing, and shield effectiveness is good; Be provided with the decoration line, can increase the aesthetic appearance of product, improve the market competitiveness of product.
