Description

A kind of silicon rubber insulation braided wire

Technical field

This utility model belongs to electricity field, is related to field of cables, specifically a kind of silicon rubber insulation braided wire.

Background technology

Traditional electric wire, access circuit it, after life-time service, as how many conductors has heat generation, can cause Conductor is merged with insulator, is burnt insulator, and then is caused insulation effect to be deteriorated, can easy leak source electrocution conditions；And electric wire After long, due to the heat effect of electric current, can be softened due to heat effect between the electric wire of directly contact so that insulator it Between mutually it is glutinous together, easily form that circuit is short to wait fault.

Utility model content

In order to solve the above problems, this utility model provides a kind of silicon rubber insulation braided wire, concrete technical scheme It is as follows：

A kind of silicon rubber insulation braided wire, including some metal conductor layers, insulating barrier, thermal insulation layer, fiber braiding layer, institute State, the external insulating barrier of the tin layers, the metallic conductor of some external tin layers and insulating barrier Layer constitutes cable core, the external thermal insulation layer of the cable core, the external fiber braiding layer of the thermal insulation layer.

In the electric wire, outside metal conductor layer, have tin liquor, effectively can prevent together with metal conductor layer and insulating barrier from sticking And then cause failure of insulation；Then some metallic conductors equipped with tin layers and insulating barrier are collectively formed into cable core, is not traditional Directly each metallic conductor is directly wound into together, so can effectively prevent that each metal is caused due to heating effect of current Insulating barrier bonding outside conductor；Then the external thermal insulation layer of cable core, prevents in short circuit, wire radiating it is excessive and by amount of heat Conduct to the external world, cause extraneous combustibles on fire；And glass layer energy effective protection thermal insulation layer, it is to avoid directly clash into and destroy Heat-barrier material.

As further improvement, it is characterised in that：It is provided between the external tin layers and the metal conductor layer of insulating barrier Grid.

As further improvement, it is characterised in that：The cross sectional shape of the grid is X-type.

Separate each metallic conductor using grid, it is to avoid artificial treatment not at that time, can be suffered mutually compact between conductor The situation occurs, it is ensured that the interval between each metallic conductor so that the insulating barrier of its outer layer will not be glued due to heat effect Close.

The beneficial effects of the utility model：Metallic conductor can be avoided to occur bonding during life-time service with insulating barrier Phenomenon and cause insulation effect to be deteriorated, each parcel insulating barrier metallic conductor between be also not in due to heating effect of current and Soften the phenomenon of bonding, and insulating barrier using through intensive treatment silicone rubber, its intensity has also been obtained very with resistance to elevated temperatures It is big to improve.

Description of the drawings

Structural representations of the Fig. 1 for silicon rubber insulation braided wire.

Fig. 2 is the positive structure schematic of each metal level.

Wherein：1- metal conductor layers, 2- tin layers, 3- insulating barriers, 4- cable cores, 5- thermal insulation layers, 6- fiber braiding layers, 7- lattice Grid.

Specific embodiment

In order to deepen, to understanding of the present utility model, this utility model to be done further below in conjunction with drawings and Examples Describe in detail, the embodiment is only used for explaining this utility model, protection domain is not constituted and is limited.

A kind of silicon rubber insulation braided wire, including some metal conductor layers 1, insulating barrier 3, thermal insulation layer 5, fiber braiding layer 6, tin layers 2,2 external insulating barrier 3 of the tin layers, some external tin layers 2 and insulating barrier 3 are scribbled outside the metal conductor layer 1 Metal conductor layer 1 constitute cable core 4,4 external thermal insulation layer 5 of the cable core, 5 external fiber braiding layer 5 of the thermal insulation layer are described outer Connect, the cross sectional shape of the grid 7 is X-type.

A kind of above-mentioned silicon rubber insulation braided wire processing technique, with copper as metallic conductor, comprises the following steps that：

Step one：Copper conductor material is immersed in tin liquor, then wire drawing, is placed in tin liquor, then wire drawing, followed with this Ring three times, constitutes stanniferous copper conductor silk, and in being immersed in tin liquor every time, the time is 8 minutes；

Step 2：White carbon black, 1% that mass fraction is 3% are added in silicone rubber of the methyl vinyl silicone rubber for base rubber Silicone oil, after mixing, Bao Tong, filtration, is then mixed with vulcanizing agent, through molding, extrusion, forms insulating barrier, the silicon rubber Glue is 1 with vulcanizing agent mass ratio：2；

Step 3：After insulating barrier in step 2 is softened under the hot-air of normal pressure, wrap stanniferous in step one Metallic conductor silk, extrudes integral；

Step 4：After product obtained by some step 3 is spaced with grid, cable core is constituted；

Step 5：Heat-barrier material is taken, molding is extruded into thermal insulation layer；

Step 6：With the cable core in the thermal insulation layer parcel step 4 in step 5；

Step 7：Glass fibre is taken, then knitting forming wraps up the product in step 6, complete Product processing.

Electric wire in the present embodiment, can avoid copper conductor from occurring bonding during life-time service with silicone rubber insulation layer Phenomenon, by grid between the metallic conductor of each parcel insulating barrier, is also not in soften bonding due to heating effect of current Phenomenon, and insulating barrier is using through intensive treatment silicone rubber, and its intensity has also obtained large increase with resistance to elevated temperatures.
