Description
Technical Field
The utility model relates to a tinned wire field especially relates to a multiple fire-retardant tinned wire.
Background
In order to improve the anti-oxidation effect and the welding performance of the copper wire, the surface of the copper wire can be subjected to tinning treatment to obtain a tinned copper wire. The tinned copper wire has good conductivity and can be used as a conductive core of various cables and wires.
The flame retardant property of the tinned copper wire mainly depends on the insulating sheath on the surface of the tinned copper wire, and if the insulating sheath is damaged or is damaged by high-temperature flame, the flame retardant effect is lost. In order to improve the flame retardant performance of the tinned copper wire, the invention patent application with the application number of 202110411436.X discloses a fireproof flame-retardant tinned copper wire for 5G communication, wherein the surface of the tinned copper wire is treated by a coating agent, so that a flame retardant solution can be carried and adhered to the tinned copper wire, and the flame retardant performance is further improved. In fact, the coating agent can carry less flame retardant liquid, the improvement on the flame retardant effect is limited, and improvement is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a multiple fire-retardant tinned wire carries out multiple fire-retardant, promotes flame retardant efficiency.
To achieve the purpose, the utility model adopts the following technical proposal:
a multi-flame retardant tinned copper wire comprising: copper core, tin coating, first fire-retardant layer, around covering and the fire-retardant layer of second, the tin coating sets up the surface at the copper core, first fire-retardant layer sets up the lateral surface at the tin coating, first fire-retardant layer includes several fire-retardant hoses, it has the fire retardant to fill in the fire-retardant hose, include the heat-resisting fire-retardant silk of at least one deck spiral winding at first fire-retardant outside of the layers around the covering, the fire-retardant layer of second includes that at least one deck cladding is at the fire-retardant sheath around the covering lateral surface.
Wherein, the flame retardant is a granular flame retardant.
Wherein, the flame retardant hose annular array distributes in the lateral surface of tin coating.
The flame-retardant sheath is a PVC insulating flame-retardant sheath.
Wherein, the heat-resistant flame-retardant wire adopts glass fiber or metal wire.
Wherein, a flame retardant coating is arranged on the surface of the tinning layer.
The utility model has the advantages that: the utility model provides a multiple fire-retardant tinned wire, carries out the apparent protection through fire-retardant sheath, carries out first heavy fire-retardant, through the contact of blocking flame and first fire-retardant layer around the covering, carries out the heavy fire-retardant of second, and rethread fire-retardant hose carries out the third heavy fire-retardant, and fire-retardant hose is burnt out the back, exposes the fire retardant and gets into the fourth heavy fire-retardant, can also increase fire-retardant coating and carry out the fifth heavy fire-retardant, has promoted flame retardant efficiency greatly, has ensured tinned wire's safety in utilization.

fig. 2 is a schematic view showing the construction of the flame retardant hose of fig. 1.
Detailed Description
The technical solution of the present invention is further described by the specific embodiment with reference to fig. 1 to fig. 2.
A multi-flame retardant tin-plated copper wire as shown in fig. 1, comprising: copper core 5, tin coating 4, first fire-retardant layer, around covering 2 and the fire-retardant layer 1 of second, tin coating 4 sets up at copper core 5's surface, promotes copper core 5's anti-oxidant effect and welding performance.
The first flame retardant layer is arranged on the outer side surface of the tin coating 4 and comprises a plurality of flame retardant hoses 6, in the embodiment, the flame retardant hoses 6 are distributed on the outer side surface of the tin coating 4 in an annular array manner, as shown in fig. 1, the flame retardant hoses 6 are distributed closely, the gaps between the adjacent flame retardant hoses 6 are small, and the flame retardant protection of the tin coating 4 is carried out.
In addition, in order to improve the flame retardant effect, the surface of the tin coating 4 can be provided with a flame retardant coating, and flame retardant protection is carried out through the flame retardant coating.
In order to improve the flame retardant effect, the flame retardant hose 6 is filled with the flame retardant 3, as shown in fig. 2, after the flame retardant hose 6 is burned out, the flame retardant 3 can be exposed, and the flame retardant can be continued to be retarded through the flame retardant 3. In this embodiment, the flame retardant 3 is a granular flame retardant, such as a granular organic phosphorus flame retardant, which can generate a cross-linked solid substance or a carbonized layer with a stable structure when heated, and has a good flame retardant effect.
