Description

Cable sheath connector {CABLE PIPE CONNECTOR}

The present invention relates to a cable sheath connector, and more particularly to a cable sheath connector connecting the cable sheath for accommodating the cable.

When embedding telecommunication and power cables in the basement, embed a large diameter protective tube underground and insert the cable directly into the protective tube or insert a plurality of small diameter receiving tubes inside the protective tube, There is a way to accommodate cables in the tube. In particular, the protective tube is composed of a synthetic resin such as polyvinyl chloride resin (polyvinyl chloride) or polyethylene (polyethylene), the outer surface is formed with a spiral groove. Spiral grooves allow deflection of the sheath to allow for free course changes.

On the other hand, in the case of the protective pipe which can be bent and deformed, the pipe must be cut in a predetermined length in a place where the buried path is sharply changed, and then the cut part must be connected again. Care must be taken to prevent foreign substances such as moisture and dust from entering. In other words, when foreign matters such as moisture, dust, or the like are damaged through the connection part, the cable may be damaged.

Accordingly, the present invention has been made to solve the above problems, the object is to provide a cable protective tube connector for connecting the protective tube firmly.

Still another object of the present invention is to provide a cable sheath connector for maintaining a hermetic state so that moisture or other foreign matter does not enter the inside of the sheath through the connection of the sheath.

A characteristic feature of the present invention for achieving this object is a cable sheath connector for connecting two sheaths for receiving a cable or a receiving tube therein with a spiral groove formed along an outer surface thereof, which can be combined with the spiral grooves of the sheath. First and second split bodies which are provided with coupling protrusions respectively, and are separated from each other so as to cooperate with each other to wrap the connection portions of the two protective tubes; Fastening means for fastening the first split body and the second split body to each other such that the first split body and the second split body are tightly fixed to the protective tube connection part; And a sealing means for maintaining airtightness between the protective tube and the first split body, the protective tube and the second split body to prevent foreign substances from entering the connection part of the protective tube.

Preferably, the sealing means comprises a first seal disposed between the first split body and the protective tube, and a second seal disposed between the second split body and the protective tube.

Hereinafter, a preferred embodiment of a cable sheath connector according to the present invention will be described in detail with reference to the accompanying drawings.

First, the cable sheath will be described with reference to FIG. 1 before explaining the cable sheath connector. For convenience, one cable protective tube to be connected is defined as the first protective tube 1, and the other cable protective tube is determined as the second protective tube 2. As shown in FIG. 1, the first protective tube 1 and the second protective tube 2 can be seen that spiral grooves 1a and 2a are formed along the circumferential direction thereof. Of course, the first and second protective tubes (1, 2) is made of a synthetic resin insulating material.

On the other hand, the cable protective tube connector according to the present invention is configured to connect the first protective tube 1 and the second protective tube (2) facing each other. Looking at this in detail, the cable sheath connector has a body 10 surrounding the outer surface of the first protective tube 1 and the second protective tube 2 butted as shown in FIGS. 1 and 2 and 3. The body 10 is divided into a first split body 12 having a semi-circular cross section and a second split body 14 also having a semi-circular cross section. The first split body 12 and the second split body 14 are configured to surround the connecting portion of the first protective tube 1 and the second protective tube 2, which face each other and cooperate with each other.

On the other hand, the engaging projection which can be coupled to the helical grooves (1a, 2a) of the first protective tube 1 and the second protective tube (2) around the inner surface of each of the first divided body 12 and the second divided body (14) 12a and 14a are formed. These coupling protrusions 12a and 14a serve to increase the coupling force of the first split body 12 and the second split body 14 to the first protective tube 1 and the second protective tube 2. In addition, flanges 12b and 14b are formed at the upper and lower contact ends of the first divided body 12 and the second divided body 14 along the longitudinal direction. The flanges 12b and 14b are fastened by fastening means such as bolts B and nuts N to couple the first split body 12 and the second split body 14 to each other. (1) and the second protective tube (2) to be firmly connected to each other.

On the other hand, the first split body 12 and the second split body 14 is composed of a hard synthetic resin material excellent in electrical insulation and strength.

Referring back to Figure 1, the protective tube connector of the present invention has a sealing means for maintaining the airtight between the first and second protective tube (1, 2) and the body (10). The sealing means includes a first seal 20 disposed between the first split body 12 and the first and second protective tubes 1 and 2, and the second split body 14 and the first and second bodies. It consists of the 2nd seal 30 arrange | positioned between the protective pipes 1 and 2. As shown in FIG. In particular, the first seal 20 and the second seal 30 are arranged on both sides of the first and second split bodies 12 and 14 to seal between the first and second protective pipes 1 and 2. Upper and lower second sealing portions 24 and 34 sealing between the first sealing portions 22 and 32 and the flanges 12b and 14b of the first and second dividing bodies 14. It is composed of

The first seal 20 and the second seal 30 are composed of the first split body 12 and the first and second protective tubes 1 and 2, and the second split body 14 and the first and second protective tubes. Sealing between (1, 2) prevents foreign matter from penetrating into the inside of the first protective tube 1 and the second protective tube 2. In particular, the first seal 20 and the second seal 30 are fastened by fastening the flanges 12b and 14b of the first split body 12 and the second split body 14 by fastening means. As shown in the drawing, the first and second split bodies 12 and 14 and the first and second protective tubes 1 and 2 are in close contact with each other to increase the sealing effect.

Here, the first seal 20 and the second seal 30 are not only excellent in insulation, heat resistance, and oxidation resistance, but also strong in resistance to polar materials and excellent in charge of synthetic ethylene-propylene-diene terpolymers (EPDM). It is preferable that it consists of.

As described above, the protective tube connector of the present invention connects the first protective tube 1 and the second protective tube 2 through the first split body 12 and the second split body 14 having coupling protrusions 12a and 14a. After wrapping, by fastening it with a fastening means, it is possible to more firmly connect the first protective tube 1 and the first protective tube (1). In particular, by sealing between the first and second protective pipes (1, 2) and the first and second split bodies (12, 14) through a pair of first and second seals (20, 30), such as moisture dust and the like. It has an effect of preventing foreign matter from entering the protective tube.

In the above described a preferred embodiment of the present invention by way of example, the scope of the present invention is not limited only to this specific embodiment, it can be appropriately changed within the scope described in the utility model registration claims.

As described above, the cable protective tube connector according to the present invention wraps the first protective tube and the second protective tube through the first split body and the second split body having a coupling protrusion, and then tighten the first protective tube and the first protective tube. It has an effect that can be connected more firmly. In particular, by sealing between the first and second protective tubes and the first and second split bodies through a pair of first and second seals, foreign matters such as moisture dust are prevented from entering the protective tube.
