Embodiment Construction

[0016] As shown in the figure, the present invention is a cable sheath with a seal for the cable trench to enter the underground structure. The material is especially PVC, and PE and PP materials can also be used. It is better to use anti-aging PVC, and the preparation process is mature. The rubber sealing layer 2 and the supporting member 2-1 are similar in shape, and both adopt rubber products. figure 1 Both ends of the valve are sealing parts, but in actual use, the sealing at one end can often meet the requirements. The outer casing is built in the building, and the protrusions on the outer circumference are used as anti-slip stoppers.

[0017] The end of the outer casing 1 is a frustum-shaped cylinder, and the sealing rubber layer 4 is also in the shape of a frustum-shaped cylinder, which is matched to be placed in the frustum-shaped cylinder. Fixing ring (Haff with spiral fixing ring) 9, tool fastening groove 9-1, pressing step 9-2, the end of outer casing 1 is provided...

Abstract

A cable sheath waterproof plastic sealing element is composed of an outer sleeve (1) and a sealing part. At least one end of the outer sleeve is provided with the sealing part which is composed of a rubber sealing layer, a supporting element and a fixing ring. The rubber sealing layer (2) and the supporting element (2-1) are provided with cable holes (3) to be passed through; matched with the thread mouth of the outer sleeve, the fixing ring is used for fixing the rubber sealing layer and the supporting element; and a plurality of cable holes are cut on the rubber sealing layer and the supporting element. The guidance and protection device for the extension of electric or optical cables and the like into a building form a trench is concise and reliable in structure, convenient in installation and far superior to products of the prior art in sealing effect, avoids that groundwater enters an underground structure along the electric cable, and can satisfy the water tight (also insect prevention and rat proof) performance requirements of various engineering structures.

Description

technical field [0001] The invention relates to a connector and a protection device for cables such as cables and optical cables. Background technique [0002] Cables (including cables, etc.) need to use sheaths when they enter buildings (including underground buildings) from trenches, especially seals that are waterproof and insect-proof. They are used to isolate and seal trenches from buildings while guiding cables and cables. For the passage of objects, existing similar waterproof sleeves, such as CN201025668 cable waterproof sleeve, are provided with rubber water-stops in the sleeve body, and the rubber water-stops are provided with cable holes. There is a rubber water stop in the casing body, and a cable hole is set in the rubber water stop. When in use, not only the cable hole can be passed through by the cable, which is convenient for installation and construction, but also the rubber water stop can be tightly connected to the cable through which the cable passes. At...
