(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

for solving present socket connecting wire when using is that the sinle silk after directly will skinning links to each other with the spliced pole in the socket mostly, because there is not protective part in the terminal department of connecting wire, lead to the connecting wire to expose easily at the unnecessary sinle silk of socket installation back, thereby cause the potential safety hazard easily, simultaneously because the connecting wire mainly relies on the oversheath on the connecting wire to realize the protection of connecting wire in the use, and the connecting wire oversheath is lower to the tolerance degree of fire, and easy burning, thereby lead to the fire-retardant fire resistance of socket connecting wire relatively poor, greatly reduced the problem of the security of socket connecting wire when using, the utility model discloses a design of elastic insulation cover, fire-retardant layer and flame retardant coating, can realize the effective parcel of the unnecessary exposed sinle silk of socket connecting wire terminal department under the effect of elastic insulation cover on the one hand, avoid the exposure of socket connecting wire terminal department unnecessary sinle silk after the installation, on the other hand through add flame retardant coating and fire-retardant coating on the basis of original connecting wire, effectively improved the flame retardant coating of socket connecting wire, avoided the burning phenomenon of socket connecting wire in the use, improved the security of socket connecting wire when using greatly.
