Abstract
The invention relates to a magnetic single-wall heat shrinkage sleeve, which comprises a polyolefin base material and magnetic powder mixed therein, wherein weight percentage of the polyolefin base material is 20%-70%, and weight percentage of the magnetic powder is 30%-80%. The sleeve has magnetic powder, so the magnetic heat shrinkage sleeve can substitute a traditional magnetic cap, and the magnetic single-wall heat shrinkage sleeve has the advantage of small volume compared with the magnetic cap; and simultaneously, inductance of an inductor can be increased, and the cost of the inductor can be saved.
Description
Technical field
The present invention relates to a kind of magnetic single wall thermal contraction casing tube.
Background technology
Inducer has obtained using widely in the design of various electronic circuits as a kind of main electronic devices and components, is to realize the indispensable components and parts of many circuit functions.
Along with the various electronicss development trend of miniaturization and lightness day by day, comprise that the electronic devices and components of the formation electronics of inducer also develop in the direction towards miniaturization and lightness constantly.For this reason, those skilled in the art has done a large amount of research and development aspect production technique or aspect product configurations, designs the inducer that is suitable for producing with practical application of all kinds.Yet, generally be the magnetic cap to be set prevent magnetic interference on the existing inducer, and next anti-tampering with the magnetic cap, significantly the volume of this inducer of increase causes the increase of inducer cost again.
Summary of the invention
It is good that the technical problem to be solved in the present invention provides a kind of antimagnetic interference effect, can reduce the magnetic single wall thermal contraction casing tube of inducer volume and cost simultaneously.The present invention is achieved through the following technical solutions:
Magnetic single wall thermal contraction casing tube of the present invention comprises polyolefin substrate and mixing magnetic within it, and it is 20%～70% that described Polyolefin and auxiliary agent accounts for weight percent, and it is 30%～80% that described magnetic accounts for weight percent.
As preferably, described polyolefin substrate is polyethylene, ethylene-vinyl acetate copolymer and derivative thereof or several persons' a mixture.
As preferably, described magnetic thermal contraction casing tube comprises that also accounting for weight percent is 0%～50% fire retardant.
Magnetic single wall thermal contraction casing tube of the present invention owing to be mixed with magnetic, can substitute traditional magnetic cap, and is good except having antimagnetic interference effect, relative magnetic cap, the advantage that volume is little; Simultaneously, the sensibility reciprocal of inductance can be increased, the cost of inductance can be saved.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the sectional view of magnetic single wall thermal contraction casing tube of the present invention.
Embodiment
As shown in Figure 1, the left side is for before shrinking, and the right is for after shrinking, and magnetic single wall thermal contraction casing tube of the present invention comprises polyolefine and the magnetic that is blended in the polyolefine.Because contain magnetic in the sleeve pipe, this magnetic sleeve pipe can substitute traditional magnetic cap, be installed on the inducer after thermosol contraction again, to be fixed on the inducer.Relative magnetic cap, it is good to have an antimagnetic interference effect, the advantage that volume is little; Simultaneously, the sensibility reciprocal of inductance can be increased, the cost of inductance can be saved.Wherein, described polyolefin substrate can be the material of polyethylene, ethylene-vinyl acetate copolymer and derivative thereof or several persons' manufacturing thermal contraction casing tubes such as mixture.

Embodiment three:
Described magnetic single wall thermal contraction casing tube comprises polyethylene, ethylene-vinyl acetate copolymer and auxiliary agent and magnetic, it is 10%～60% that described polyethylene accounts for weight percent, it is 10%～60% that described ethylene-vinyl acetate copolymer and auxiliary agent account for weight percent, and it is 30%～80% that described magnetic accounts for weight percent.Certainly, described magnetic single wall thermal contraction casing tube can also comprise that accounting for weight percent is 0%～50% fire retardant.In the present embodiment, described magnetic single wall thermal contraction casing tube comprises that accounting for weight percent is 30% polyethylene, account for weight percent and be 30% ethylene-vinyl acetate copolymer and auxiliary agent, account for weight percent and be 35% magnetic, account for weight percent and be 5% fire retardant.Above material fully mixes and forms.
Magnetic single wall thermal contraction casing tube of the present invention owing to be mixed with magnetic, can substitute traditional magnetic cap, and is good except having antimagnetic interference effect, and the magnetic cap also has the little advantage of volume relatively; Simultaneously, the sensibility reciprocal of inductance can be increased, the cost of inductance can be saved.
The foregoing description; it is an example of the present invention; be not to be used for limiting enforcement of the present invention and interest field, all equivalences of being done according to the described structure fabrication processing method of the present patent application scope of patent protection change and modify, and all should be included in the present patent application claim.
