Problems solved by technology
From the introduction of the patent, there are two problems: one is that the two ends of the shell are symmetrically provided with finger-shaped sheaths and access cable holes, and the finger-shaped sheaths pass through the access cable holes
The photoelectric connection protection module is a tubular cylinder whose outer diameter is smaller than the cable inlet module and the cable outlet module, and the connection of the optical fiber and the connection of the power cable core are carried out in this tubular cylinder, and the limitation of the operating space will bring Very inconvenient to operate

Embodiment Construction
[0037] See figure 1 , figure 2 and image 3 , an optical fiber composite power cable intermediate splicing box, comprising a housing 1, a photoelectric separation finger 2, an optical fiber splicing plate 3 and a sealing and fastening device 4.
[0038] The shell 1 is divided into an upper shell 11 and a lower shell 12 which are mutually symmetrical, and are detachably fixed together by a sealing fastening device 4; the outer surfaces of the upper shell 11 and the lower shell 12 of the shell 1 are continuous smooth surfaces, and the shell 1 is provided with a sealing gasket groove 13, and the sealing gasket groove 13 includes the inner side of the flange 41 and the contact between the housing 1 and the outer sheath of the optical fiber composite cable. The function of the shell 1 is mainly to strengthen the mechanical protection and moisture-proof protection of the composite cable joint. The casing 1 is generally made of stainless steel or materials with similar strength a...

The invention discloses an intermediate splicing closure and a splicing method for an optical fiber composite power cable. The splicing closure comprises a shell, two photoelectric separation fingerstalls, an optical fiber splicing plate and a sealing and fastening device, wherein the shell is divided into an upper shell and a lower shell, which are symmetric, and are detachably fixed through the sealing and fastening device; and each of the two photoelectric separation fingerstalls is a cylindrical shrinkable tube with a one-inlet two-outlet or one-inlet multi-outlet structure. The shell of the splicing closure is divided into an upper part and a lower part, and splicing operation over a cable conductor is separated from combination mounting operation over the upper and lower parts of the shell, namely the splicing operation over the cable conductor is unlimited by the space of the shell, so that the splicing operation over the optical fiber composite power cable is facilitated, the power and communication transmission stability of an intermediate splicing joint for the optical fiber composite power cable can be ensured, and an anti-pressure effect, a waterproof effect and the like are achieved.
Description
technical field [0001] The invention relates to a cable extension accessory, in particular to an optical fiber composite power cable intermediate extension box and an extension method thereof. Background technique [0002] Optical fiber composite power cable is a new type of optical fiber composite cable used in power lines. It has the functions of ordinary cable, communication optical cable and online detection. It is used to carry out services such as "three-network integration" of telecommunication network, broadcasting network, and Internet content transmission, combined with online monitoring power network construction, and finally realizes the construction of a strong and intelligent large power grid. Structurally, the optical fiber composite cable is mainly composed of a power core for transmitting power and an optical unit for transmitting communication. The metal conductor cable core for power transmission is composed of metal conductor and insulation, and the core...
