(Industrial Application Field) The present invention provides an anti-corrosion structure for the terminal end of cables and wire ropes (hereinafter collectively referred to as cables), more specifically, a socket that is a fixing structure for the cable end, and an anti-corrosion layer for the cable. This invention relates to a corrosion-protected terminal portion of a cable, which is coated with a corrosion-protective layer that improves the restraint between the socket and the heat-shrink tube for terminal corrosion protection on the outer periphery. (Prior art) Cables are used as high tensile strength materials for various purposes, but cables made of steel are used outdoors, such as on suspension bridges and cable-stayed bridges, or in corrosive environments, such as under the sea or at sea. Since there are concerns about localized corrosion and stress corrosion cracking, anti-corrosion measures are extremely important. Therefore, in order to use the cable for a long period of time, it is necessary to apply a more complete anti-corrosion layer, and for example, measures such as extrusion coating the cable with polyethylene resin etc. are implemented (for example, Japanese Patent Publication No. 10156/1983). (See Kaisho 60-241545, etc.) Conventionally, in the anti-corrosion terminal part of a cable coated with this anti-corrosion layer, a socket is used to restrain the socket and the heat-shrinkable tube for terminal corrosion protection on the outer periphery, which is applied between the socket, which is the fixing structure, and the anti-corrosion layer of the cable. No special consideration was given to the
For example, it was as shown in FIG. In Fig. 3, 1 is a cable, 2 is an extruded anti-corrosion layer on top of 1, such as an extruded polyethylene anti-corrosive layer, 3 is a socket which is a cable fixing structure, 4 is an epoxy resin, and 5 is a cable.
6 is a zinc-copper alloy (the wire is fixed to the socket by pouring the zinc-copper alloy between the loose wires in the socket), 6 is a heat-shrink tube for terminal corrosion protection, and the heat-shrink tube is a metal socket 3
and the anti-corrosion layer 2 of the cable. Note that 7 is a sealing compound, and 8 is a sleeve portion of the socket 3. (Problems to be Solved by the Invention) In other words, in the conventional terminal part described above, the outer surface of the cable side sleeve part 8, where the heat shrinkable tube of the metal socket that is the fixing structure is located, was smooth;
For example, if the cable's anti-corrosion layer shrinks due to temperature changes, or if the cable stretches under load and the anti-corrosion layer shrinks relatively, the heat-shrinkable tube for terminal corrosion protection will not be able to easily be used with just the adhesive strength of the anti-corrosion tube. There was a problem with the water leaking out (this leakage allowed water to enter). In view of the above, the present invention has been developed to solve these problems. (Means for Solving the Problems) That is, the present invention utilizes a metal socket as a cable fixing structure to be attached to both ends of a cable coated with an anti-corrosion layer made of an extruded coating layer of synthetic resin such as polyethylene resin. In the corrosion-proof terminal part, a convex or concave fixing part is provided on the surface of the cable-side sleeve of the metal socket, which is the fixing structure, and is applied between the metal socket, which is the fixing structure, and the anti-corrosion layer of the cable. By positioning the heat-shrinkable tube beyond the convex or concave fixing part and wrapping it with a binding wire such as copper wire, metal tape, or a strip, it is possible to prevent the corrosion protection layer from expanding or contracting due to temperature or the cable's strength due to load. Due to relative displacement between the cable anti-corrosion layer and the cable due to expansion, contraction, etc., when the anti-corrosion tube for the terminal is pulled by the anti-corrosion layer of the cable from the metal socket that is the fixing structure, the anti-corrosion tube for the anti-corrosion of the terminal The adhesive strength of the tube restrains the corrosion-proofing heat-shrinkable tube from slipping during the above-mentioned tensioning process. When such restraint is performed, the relative displacement between the cable and the corrosion protection layer of the cable described above will be reduced to 1 in Fig. 1, which will be described later.
The heat-shrinkable tube for corrosion protection at the end shown in No. 2 is absorbed at the portion where it deforms following the expansion and contraction of the corrosion protection layer of the cable. Furthermore, the anti-corrosion layer of the cable and the anti-corrosion heat-shrinkable tube at the terminal end are restrained by the adhesive force of the heat-shrinkable tube. The present invention will be explained below in an easy-to-understand manner. 1 and 2 show specific embodiments of the present invention, in which 1 is a cable, 2 is an anti-corrosion layer made of extruded polyethylene, etc., 3 is a metal socket that is a cable fixing structure, and 4 is an epoxy resin. , 5 is a zinc-copper alloy (the wire is fixed in the socket by pouring the zinc-copper alloy between the loose wires in the socket), and 6 is a heat shrinkage applied over the socket 3 and anti-corrosion layer 2 to protect the terminal from corrosion. Tube 7 is the sealing compound. The heat-shrinkable tube is, for example, a crosslinked polyethylene tube whose back surface is coated with a hot-melt adhesive, and is shrunk and integrated by heating. In the present invention, the above is particularly constructed as follows. The metal socket 3, which is the fixing structure, has a convex fixing part 10 or a concave fixing part 1 on the cable side sleeve part 8.
0', and the terminal corrosion prevention heat shrink tube 6 is attached to the convex fixing part 10 or the concave fixing part 10' of the socket 3.
It is located beyond this and is firmly fixed thereto with a binding wire or a band-shaped body 11. The convex fixing part 10 or the concave fixing part 10' is formed by spot welding a galvanized mild steel wire or the like to a metal socket serving as the fixing structure, and the binding wire or strip is made of soft copper, for example. The heat shrink tube can be fixed by wrapping wire or metal tape such as stainless steel tape. (Function) In the above case, since the heat-shrinkable tube for terminal corrosion protection is firmly fixed to the convex or concave fixing part with the binding wire or strip, the terminal corrosion protection tube can be easily fixed by expansion and contraction of the cable's corrosion protection layer. The anti-corrosion heat shrink tube will not fall out. (Example) Examples of the present invention will be described below. Confirmation of pull-out resistance and water resistance The pull-out resistance and water resistance of the terminal corrosion-proof structure according to the present invention have been confirmed through experiments. The experimental specimen is
It consists of an anti-corrosion layer that is the same size as a cable made of 109 galvanized copper wires with a diameter of 7 mm, and a metal socket that serves as the anchoring structure for the anti-corrosion layer. As shown in Figure 4, the heat-shrinkable tube 6 for corrosion protection at the terminal part is applied in two layers, and the thickness of the two layers after shrinkage is 3.6 mm, so that the adhesion between the cable's corrosion protection layer and the cable is completely maintained. This is an experimental specimen assuming a broken state, that is, a state in which the maximum tensile force is applied to the heat-shrinkable tube. In Fig. 4, the same symbols as in Fig. 1 indicate the same parts, and 14 is a polyethylene pipe, 15 is a jig,
16 is the fixed side, 17 is the load side, L 1 = 550mm, L 2 =
400mm, L3 =100mm, L4 =150mm, L5 =150mm, L6
= 100mm, D 1 = 165mmφ, and D 2 = 120mmφ. When the above specimen was statically stretched at room temperature (23°C), the heat-shrinkable tube did not shift from the socket 3, which is the anchoring structure, and the heat-shrinkable tube for corrosion protection at the terminal end, shown at 12 in Figure 1, was attached to the cable. The part that deforms following the expansion and contraction of the anti-corrosion layer expands with the load as shown in Figure 5 (load-elongation curve) and Figure 6 (elongation status of anti-corrosion heat shrink tube), and the above assumed maximum It has been confirmed that the anti-corrosion structure of the terminal part according to the present invention has a sufficient function of restraining the anti-corrosion heat-shrinkable tube even under tensile loads. The same experimental specimen 18 as above was immersed in artificial seawater (3% Nac) 19 for 4 months as shown in Figure 7, and its electrical insulation (water resistance) was measured. As shown, 0.6× even after 4 months
It has been confirmed that electrical insulation of 10 10 Ω can be obtained and that it has sufficient water resistance. Note that 20 in FIG. 7 is a super-insulated resistor.
