ある。However, according to the conventional method for sealing the inlet / outlet holes of various cables to ensure watertightness, a spacer is required for the cables in terms of parts,
The work is complicated by winding rubber tape and sealing tape, and removing and replacing the sealing tape is particularly troublesome when adding cables and performing maintenance.In addition, it is necessary to replace the tapered end face, spacers, and rubber tape. As a result, work time and repair costs were lost, which was a problem. The present invention is intended to eliminate these drawbacks of the related art, and forms a cable insertion hole by cutting off a separation slit in an end face plate corresponding to various cables having different diameters to insert and remove a cable housing. It can be safely applied without a sealing tape, the assembly and dismantling work time can be greatly shortened, and at the same time, the end face sealing member in the cable connection case can be configured at low cost without additional parts such as cables and replacement of parts during maintenance. It is intended to be provided in a cheap form.

交換不要でコストの大幅な低減も図れることになる。When inserting the cable into the cable insertion hole, if the cable diameter is large, the remaining meat portion of the slit having the same diameter around the cable insertion hole is cut off from the separation slit on site. The cable fitting insertion hole having a pressing piece around the hole can be made to correspond to the opening by cutting off the V groove for use, and the watertightness can be secured after the cable is inserted and assembled. In particular, the pressing piece is tightly covered on the outer circumference of the cable, and the cable fitting hole with a large and small diameter difference makes it easy to ensure the watertightness of the cable without a sealing tape, and it is also easy to accommodate cables of different diameters.
Since no sealing tape is required, the assembly and dismantling work time can be greatly shortened, and replacement of parts and the like is not required even at the time of expansion or maintenance, resulting in a significant cost reduction.

変位にも十分水密性を保持して用いられる。Since the through holes formed by the cable fitting holes 12, 13 and the like have separation slits around them, the slits selected according to the cable diameter are cut off without winding spacers or airtight tape. The outer peripheral surface of the cable can be brought into close contact with the inner and outer sides of the superposed end plate by the insertion holes having different diameter holes. The support wire insertion hole 14 and the cable insertion holes 12 and 13 have slits 15 1
So that it can be used with both cable types that are connected with each other and the connection part of the support wire and the cable is continuous with the covering body, and the cable type that is connected at intervals with a connecting piece is there. That is, the pair of end face plates 6 1 and 6 1 are used by being bent from the hinge portion 6 2 and overlapped with each other, and the one end face plate 6 1 which is half the thickness thereof has the support wire fitting insertion hole 14 and the base line cable fitting. insertion hole 13 may not contain no gap slit between, but the end face plate 61 of the other half is provided with a slightly slits gapped, both may be provided a slit with no gaps. In this case, the cable type in which the connecting portion between the support wire and the cable is continuous with the covering body is separated and assembled and used as necessary. Furthermore, the former end face plate 61 is provided with insertion hole fitting the small diameter relative to the other, is significantly lower for all or part hardness (Hardness 0) rubber,
The latter end plates 61 is provided with a large diameter insertion hole with respect to the other, and have a rubber hardness (hardness of 30) to withstand the external pressure or the like, by the difference of the structure and hardness, the former In the case of a cable, even if there is a connection between the support wire and the cable, one half has low hardness, so it will be expanded by the thickness of the cable connection, and the other half will adapt to the cable connection. The watertightness after assembly is ensured by the shape. In the case of the latter cable with support wire, by assembling so that the harder end face plate 6 1 is on the outer side, the inner end face plate 6 1 with low hardness ensures water tightness, and the large and small diameter With the combination of the fitting holes, it is used with sufficient watertightness even when the cable is displaced.

ている。In this case, one end face plate 6 1 of the end face sealing member 6 is made of rubber having a hardness of 0 and the other end face plate 6 1 is made of rubber having a hardness of 30, or the outer side of the one end face plate 6 1 is made. With a hardness of 30 and rubber having a hardness of 0 inside is laminated especially around the inside of the fitting insertion hole, or the hardness between the support wire fitting insertion hole 14 and the cable fitting insertion hole 13 of one end face plate 61 is 0. rubber also integrally formed with minimal partly on the required characteristics, also can be created end plates 61 singly or in combination with synthetic resin instead of rubber, the end face plate 61 Is an appropriate hardness, for example, a Shore hardness of 5 to 20 degrees,
Both can also be made into end plates with similar hardness.
Since the cable diameter and the support wire diameter is various, Yes put several slits for each cable to the middle of the thickness direction of the end plate 61, and the fitting hole diameter chosen by cutting off on site It can be adapted according to the cable diameter.

できる。According to the present invention, there is provided a cylindrical case which covers the periphery of a cable connecting portion and which is radially separable or separable.
In a cable connecting case having end face seal members for inserting and pulling cables in and out of both end faces of the tubular case, the end face seal members are formed by superposing a pair of elastic end face plates, and the opposite end face plates are respectively large. A ring-shaped separation slit with a small diameter difference, cable insertion hole, support wire insertion hole for overhead wiring or base line, and a part of the end face plate thickness part continuous around each insertion hole And a ring-shaped V-shaped groove for separation having a diameter smaller than each of the separation slits is formed in the continuous portion of the end face plate thick portion with a space around the inner circumference of each of the separation slits. It ensures watertightness and is used by adapting various cables with different diameters by cutting off the separation slit, and can be safely applied to the entry and exit of the housing of the cable without a sealing tape,
Assembling and disassembling work time has been greatly shortened, and at the same time it can be handled at low cost without changing parts when adding or maintaining cables. At the same time, the posture of the end face seal member in the case is stable, and even cable displacement is possible. The end face seal member easily keeps the watertightness and is easy to handle, which facilitates the assembling work, and prevents the deformation of the housing of the cable connection part, which enhances the safety and airtightness and reliability. Can be greatly improved.
