Abstract

The utility model discloses a knitting yarn material structure that fire behaviour is good, what solve is that the current USB compiles the not good problem of flame retardant efficiency of yarn material. This product is including the transmission heart yearn, the outside cladding of transmission heart yearn has the insulating layer and the outside cladding of insulating layer has fire-retardant layer, the outside cladding of fire-retardant layer has the sheath of insulating material preparation and the outside cladding of sheath has the yarn layer of weaving of fire-retardant yarn preparation, this product uses the better insulating material of fire-retardant insulating properties and weaves the yarn layer, through the fire behaviour who promotes insulating material and yarn, not only have high swing performance and high wear resistance, and the fire behaviour of wire rod reaches VW-1 requirement in UL1561, satisfy UL 9990's requirement. The product has high swinging performance and high wear resistance, the flame retardant performance of the wire reaches the VW-1 requirement in UL1561, the UL9990 requirement is met, and the market prospect is wide.

Description

Weaving yarn material structure that fire behaviour is good

Technical Field

The utility model relates to a compile yarn material field, specifically be a structure of compiling yarn material that fire behaviour is good.

Background

The USB interface is the most widely used external bus standard in the PC field, and is used to standardize the connection and communication between the computer and the external device, and the USB interface supports the plug and play and hot plug functions of the device. The USB data line is a connecting line of a USB interface and is used for connection and communication between a computer and external equipment, and also can be used for charging of a mobile phone and connection with the outside.

At present, the conventional USB braided yarn wire consists of a core wire, an aluminum foil, an outer shield (copper material), an outer sheath and yarn, the wire has good swinging resistance and wear resistance, but the conventional braided yarn wire is not flame-retardant and does not meet the UL9990 requirement, so that the application of the braided yarn wire is limited.

SUMMERY OF THE UTILITY MODEL

An object of the embodiment of the utility model is to provide a weaving yarn material structure that fire behaviour is good to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the embodiment of the present invention provides the following technical solutions:

the utility model provides a weaving yarn material structure that fire behaviour is good, including the transmission heart yearn, the outside cladding of transmission heart yearn has the insulating layer and the outside cladding of insulating layer has fire-retardant layer, the outside cladding of fire-retardant layer has the sheath of insulating material preparation and the outside cladding of sheath has the weaving yarn layer of fire-retardant yarn preparation, this product uses the better insulating material of fire-retardant insulating property and weaves the yarn layer, through the fire behaviour who promotes insulating material and yarn, not only have high performance and high wear resistance of swaing, and the fire behaviour of wire rod reaches VW-1 requirement in UL1561, satisfy UL 9990's requirement.

As a further scheme of the embodiment of the utility model: be provided with filler material between insulating layer and the transmission heart yearn, guarantee that the transmission heart yearn can not warp because of the extrusion, avoid the transmission heart yearn to warp the inefficacy that leads to.

As a further scheme of the embodiment of the utility model: the heat insulation layer is made of aluminum foil materials, is easily purchased in the market, and has good use effect and low cost.

As a further scheme of the embodiment of the utility model: the sheath is made of high flame-retardant insulating material, so that the flame-retardant effect is further enhanced.

As a further scheme of the embodiment of the utility model: the yarn weaving layer is made of any one of polyester yarns, PET (polyethylene terephthalate) yarns and PP (polypropylene) yarns, people can select different materials according to own use environments, and the yarn weaving layer is suitable for various working environments.

Compared with the prior art, the utility model discloses the beneficial effect of embodiment is:

the product has high swinging performance and high wear resistance, the flame retardant performance of the wire reaches the VW-1 requirement in UL1561, the UL9990 requirement is met, and the market prospect is wide;

this product can also set up different patterns and colour on the braided yarn layer, guarantees that the appearance is pleasing to the eye.

Drawings

Fig. 1 is a schematic structural diagram of a braided yarn material structure with good flame retardant property.

Wherein: 1-sheath, 2-transmission core wire, 3-filling material, 4-thermal insulation layer, 5-flame retardant layer and 6-yarn weaving layer.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1

The utility model provides a weaving yarn material structure that fire behaviour is good, including transmission heart yearn 2, transmission heart yearn 2's outside cladding has insulating layer 4 and the outside cladding of insulating layer 4 has fire-retardant layer 5, the outside cladding of fire-retardant layer 5 has sheath 1 of insulating material preparation and the outside cladding of sheath 1 has weaving yarn layer 6 of fire-retardant yarn preparation, this product uses the better insulating material of fire-retardant insulating property and weaves yarn layer 6, through promoting the fire behaviour of insulating material and yarn, not only there are high performance and high wear resistance of swaying, and the fire behaviour of wire rod reaches VW-1 requirement in UL1561, satisfy UL 9990's requirement.

In order to avoid failure caused by deformation of the transmission core wire 2, the filling material 3 is arranged between the heat insulation layer 4 and the transmission core wire 2, so that the transmission core wire 2 is prevented from deforming due to extrusion.
