Abstract
A heat shrinkable sheet, comprising: a through hole having the same shape in which a plurality of heat shrinkable sheets are dispersed at equal intervals; And a noise blocking member for respectively filling the through holes, wherein the noise blocking member provides a heat shrinkable sheet having different areas of one surface and the other surface.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat shrinkable sheet and a heat shrinkable tube, and more particularly to a heat shrinkable sheet and a heat shrinkable tube used for terminals of various types of electric unit mounted on an automobile.
A heat shrinkable tube is a tube having properties of shrinking in the radial direction or the longitudinal direction when cured after heating, and is mainly used for covering water or sealing water of various terminal portions to waterproof or insulate. The heat-shrinkable sheet has the same characteristics as the heat-shrinkable tube but is similar in shape to the heat-shrinkable tube. Thereby, the heat-shrinkable sheet has a purpose for sealing a wider area.
BACKGROUND ART [0002] Recently, various kinds of units mounted in automobiles are usually driven electronically, so that wires are connected to each other in a complex manner. At this time, electric wires serve as intermediaries for transporting electric power and for exchanging electrical signals.
However, due to the continuous electronicization of each type of unit, for example, the introduction of a new engine driving system such as a hybrid car, a high voltage is used in the automobile and accordingly a high voltage current flows on the inner or outer surface of the electric wire. As a result, high frequency and low frequency noise are frequently generated in the electric wires and the like, which causes a communication failure or malfunction between the various units.
SUMMARY OF THE INVENTION The present invention provides a heat shrinkable sheet and a heat shrinkable tube having a noise barrier function.
Further, the noise blocking function is uniformly provided so that the same effect can be exerted at any position of the seat and the tube, and as a result, the reliability of the electric unit is improved and at the same time, the stability of the automobile is ensured.
It is another object of the present invention to reduce noise by simply using a thermally shrinkable tube or the like conventionally used in a portion thereof without using an adhesive means including a separate adhesive or the like.
In order to solve the above problems, an embodiment of the present invention provides a heat-shrinkable sheet, comprising: a through hole having the same shape in which a plurality of heat shrinkable sheets are dispersed at equal intervals; And a noise blocking member for respectively filling the through holes, wherein the noise blocking member provides a heat shrinkable sheet having different areas of one surface and the other surface.
It is preferable that the noise shielding member is formed in a trapezoidal column shape of ferrite material.
A through hole having the same shape in which a plurality of heat shrinkable tubes are dispersed and arranged at equal intervals; And a noise shielding member for filling the through holes, respectively, wherein the noise shielding member is smaller than an area exposed to the inside of the heat shrinkable tube than an area exposed to the outside.
The noise blocking member may be formed in a trapezoidal column shape of ferrite material. And the through hole is formed so that the trapezoidal columnar shape is formed in the longitudinal direction of the heat shrinkable tube.
As described above, according to the present invention, various effects including the following can be expected. However, the present invention does not necessarily achieve the following effects.
It is possible to provide a heat shrinkable sheet and a heat shrinkable tube having a noise shielding function. Further, the noise shielding function is uniformly provided so that the same effect can be exerted at any position of the seat and the tube. As a result, the reliability of the electric unit can be improved and the stability of the vehicle can be ensured.
In addition, noise can be reduced only by using a conventionally used heat shrinkable tube or the like at the site without using an adhesive means including a separate adhesive or the like on the terminal.
