Description

The electromagnetic conductive rubber strip of modified model

Technical field

The utility model relates to the electromagnetic conductive rubber strip of a kind of modified model, refers to especially a kind ofly contact with load with less sectional area, with the electromagnetic wave phase mutual interference that prevents that the electronics spare part from being produced, also can prevent the conductive rubber strip that electromagnetic wave leaks simultaneously.

Background technology

Known, at present science and technology is constantly progressive, and many relatively high-tech products go on the market in succession, allows many consumers be more prone on various transaction and convenient.Though high-tech product allows the consumer be more prone on processing transactions and convenience, but high-tech product is in order to allow inner electronics spare part running carry out normal, all can on the housing of product, offer many through holes, the high temperature that is produced when allowing the running of electronics spare part carry out is left, perhaps bad because of case design, perhaps assemble when incomplete, also can cause housing to produce the gap, once the consumer is when using high-tech product, the electromagnetic wave that the electronics spare part of this product inside is produced just leaks easily, cause the consumer to be subjected to Electromagnetic Interference, cause the healthy of consumer to be affected.

So product is electromagnetic to leak the producer in order to reduce, putting on the electronics spare part periphery in enclosure interior can sealing-in one conductive rubber strip, electromagnetic leaking when preventing that product from using.Because the surface of aforesaid conductive rubber strip is a semi-circular shape, press when the semi-circular shape of conductive rubber strip is surperficial in the housing winding, the variable quantity that this semi-circular shape produced needs big weight or strength presses down, and the sectional area of contact is also bigger, just can make and put electronics spare part periphery complete closed, if after making assembling or maintenance, when this housing is not locked, easily produce the gap between the periphery of this storing electronics spare part and conductive rubber strip, this gap then easily allows electromagnetic wave leak, cause the phase mutual interference each other of electronics spare part, and this electromagnetic wave leaks when load is outside, also can have influence on the healthy of user.

Technology contents

Main purpose of the present utility model, be to solve above-mentioned defective, avoid defective to exist, conductive rubber strip of the present utility model utilizes less sectional area (variable quantity) to contact with load, make the electromagnetic wave that the electronics spare part produced can the phase mutual interference, can prevent that also electromagnetic wave from leaking simultaneously.

Another purpose of the present utility model is that conductive rubber strip utilizes less sectional area (variable quantity) to contact with load, so when making conductive rubber strip, used material is also economized, cost of manufacture reduces relatively.

A purpose more of the present utility model, but be that the conductive rubber strip sealing-in is placed in the periphery and the metal interlevel of electronics spare part.

Another purpose of the present utility model is that conductive rubber strip can be complied with the periphery of storing electronics spare part or the peripheral shape of load be made integrated framework, can whole framework be packaged on the periphery of storing electronics spare part or the periphery of load.

For realizing above-mentioned purpose, have one on the conductive rubber strip of the present utility model and be the long-pending less variant part of contacting section, this variant part down is extended with a bottom that can be packaged on above-mentioned second sealed portion, when conductive rubber strip contacts with load, this conductive rubber strip utilizes less sectional area (variable quantity) to contact with load, to prevent that electromagnetic wave that the electronics spare part produced can the phase mutual interference, can prevent that also electromagnetic wave from leaking simultaneously.
