Preferably, said fiber cable joint structure further comprises the cold/thermal shrinkage type insulating plastic nipple protective casing that wraps up said optical cable coupling arrangement.
Preferably, said fiber cable joint structure further comprises the multi-branched type pyrocondensation fingerstall of the single-phase heart yearn of plural cable and many fibre cores optical cable in the fine composite power cable of the heterogeneous electric light of clamping.
Preferably, described end connector is the nonmetal end connector of cold joint type mechanical type.
The present invention also comprises a kind of optical cable method of attachment, is used to connect the fine composite power cable of heterogeneous electric light, and it is characterized in that: it may further comprise the steps:
Step 1, the end connector of the fibre bundle of prefabricated certain-length and connection fibre bundle in the optical cable coupling arrangement;
Step 2, said optical cable coupling arrangement two ends respectively with the fine composite power cable of heterogeneous electric light in many fibre cores optical cable be connected.
The present invention effectively solves the optical cable intermediate head problem of the fine composite power cable of in intelligent grid is built at present, using of heterogeneous electric light.Can on the basis that keeps original non-compound polyphase electric power cable intermediate joint maturation process, realize effective connection of optical cable in the composite power cable.Solved at present to connecting the optical cable in 2 composite power cables, and need clip the problem of Single Phase Metal heart yearn of big section power cable end.Thereby practice thrift a large amount of precious materials such as copper.For the construction of fiber composite power cable and safeguard that repairing provides crucial technical conditions.
