Abstract

The invention discloses conducting foam with a breaking knife edge structure. The conducting foam with the breaking knife edge structure comprises a foam body which is of a cuboid structure. Multiple ports of different shapes and sizes are arranged in the foam body. Horizontal center lines of the multiple ports are in the same line. Breaking knife edges are arranged on four corners of the ports, slant and n-shaped. According to the conducting foam with the breaking knife edge structure, sides and corners of the ports are smooth and stable in shape, product quality is improved and the reject ratio is reduced.

Description

Contain brokenly edge of a knife structural conductive foam

Technical field

The present invention relates to the foam field, particularly relate to a kind of edge of a knife structural conductive foam that contains brokenly.

Background technology

Conducting foam is to wrap up conductive fabric at flame-retardant sponge, through after a series of processing, makes it have surface of good conductivity, and can be easy to stick with glue be with to be fixed on needs on the shielding device.Be widely used in electronic products such as PDP TV, LCD display, LCD TV, mobile phone, notebook, MP3, communication cabinet, Medical Instruments and military project, space industry.

Existing conducting foam, interface are after die-cut, and burr can appear in the corner around the interface, draw bad interface easily when playing cutter, cause conducting foam can't insert connector smoothly; And interface is more serious in die-cut back deformation ratio.

Summary of the invention

The technical problem that the present invention mainly solves provides a kind of edge of a knife structural conductive foam that contains brokenly, can make the interface corner smooth, and dimensionally stable improves the quality of products, and reduces fraction defective.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of edge of a knife structural conductive foam that contains brokenly is provided, comprise: the foam body, described foam body is rectangular structure, contain the different interface of some size shape on the described foam body, the cross central line of described interface and all is provided with brokenly the edge of a knife on four corners of described interface on same straight line, the described broken edge of a knife " Contraband " type for tilting.

In a preferred embodiment of the present invention, also be provided with some rectangular indentation on the long limit of described foam body.

In a preferred embodiment of the present invention, the cross central line of described interface deviates from the cross central line of described foam body.

In a preferred embodiment of the present invention, described interface comprises the first rectangle structure interface, the second rectangle structure interface and ellipsoidal structure interface, the described second rectangle structure interface is positioned at the centre of the described first rectangle structure interface and described ellipsoidal structure interface, and the long limit of the described first rectangle structure interface is greater than the long limit of the described second rectangle structure interface.

In a preferred embodiment of the present invention, the described first rectangle structure interface has 1, and the described second rectangle structure interface has 2, and described ellipsoidal structure interface has 2.

The invention has the beneficial effects as follows: " Contraband " type that inclination is set by four corners at interface breaks the edge of a knife, can make the interface corner smooth, dimensionally stable, can not draw bad interface shape when playing cutter, defectives such as no burr have improved product quality, have reduced the product fraction defective.

Description of drawings

Fig. 1 is the perspective view that the present invention contains brokenly one preferred embodiment of edge of a knife structural conductive foam;

The mark of each parts is as follows in the accompanying drawing: 1, foam body, 11, rectangular indentation, 2, interface, 21, the first rectangle structure interface, 22, the second rectangle structure interface, 23, the ellipsoidal structure interface, 3, the broken edge of a knife.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.

See also Fig. 1, the embodiment of the invention comprises:

A kind of edge of a knife structural conductive foam that contains brokenly, comprise: foam body 1, described foam body 1 is rectangular structure, contain the different interface of some size shape 2 on the described foam body, the cross central line of described interface 2 point-blank, and all be provided with brokenly the edge of a knife 3 on four corners of described interface 2, the described broken edge of a knife 3 " Contraband " type for tilting.

Wherein, also be provided with some rectangular indentation 11 on the long limit of described foam body 1.

The cross central line of described interface 2 deviates from the cross central line of described foam body 1.

Described interface 2 comprises the first rectangle structure interface 21, the second rectangle structure interface 22 and ellipsoidal structure interface 23, the described second rectangle structure interface 22 is positioned at the centre of the described first rectangle structure interface 21 and described ellipsoidal structure interface 23, and the long limit of the described first rectangle structure interface 21 is greater than the long limit of the described second rectangle structure interface 22.

The described first rectangle structure interface 21 has 1, and the described second rectangle structure interface 22 has 2, and described ellipsoidal structure interface 23 has 2.

The present invention is mainly used in the RO keyway of notebook computer, has surface of good conductivity, can absorb electromagnetic wave, plays shielding action.

The present invention has disclosed a kind of edge of a knife structural conductive foam that contains brokenly, the broken edge of a knife of " Contraband " type of inclination is set by four corners at interface, can make the interface corner smooth, dimensionally stable, can not draw bad interface shape when playing cutter, defectives such as no burr have improved product quality, have reduced the product fraction defective.

The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
