Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a public telephone line to perform automatic meter reading of gas meters, electric meters, water meters, etc., and uses other terminal devices such as vending machines, etc. using the public telephone line. The present invention relates to a waterproof cover for separating communication cables, which is practically used for centralized management.

[0002]

2. Description of the Related Art In the case of automatic meter reading of a gas meter using a public telephone line, a T-NCU is installed between a security device and a telephone installed in a customer to connect to the gas meter side. The communication lines are separated. At that time, since the existing protector and the newly installed T-NCU are often separated from each other, use a 4-core cable from the T-NCU to the vicinity of the protector, and 2 cores each in the vicinity of the protector. Separately, the method of connecting to the security device and the telephone device respectively is adopted. Also, for cables separated into two cores, the outer sheath of a four-core cable is used as a coating for protection,
A vinyl tape is wrapped around the part that separates the 4-core cable into 2 cores for fixing the coating and waterproofing.

[0003]

However, when the separated portion of the cable is treated by the above-mentioned method, the vinyl tape is exposed at the separated portion, so that the appearance and the waterproof effect are likely to be difficult depending on the installation site or the installer.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and the constitution thereof is as follows. 1. A lower cover formed by forming one upward semicircular 4-core cable insertion hole on the 4-core cable insertion side and two upward semicircular 2-core cable extraction holes on the 2-core cable extraction side. One downward semicircular four-core cable insertion hole facing the four-core cable insertion hole of the lower cover is formed on the core-cable insertion side, and the two-core cable extraction side faces the two-core cable extraction hole of the lower cover. An upper cover formed by forming two downward semicircular two-core cable lead-out holes, a hinge band connecting the upper cover and the lower cover so as to be expandable between the two-core cable lead-out holes, and the lower cover. And a half-divided rubber, which are housed in the upper cover, respectively, and which are connected to the 4-core cable insertion hole and are branched in the middle to form a Y-shaped cable storage hole continuing to the 2-core cable drawing hole. Seal packing and the above When you close the cover and the upper cover,
A waterproof cover for a communication cable separating portion, which comprises a lower cover and a locking member formed on the upper cover to stop the lower cover and the upper cover. 2. 2. The waterproof cover for a communication cable separating portion as described in 1 above, wherein the lower cover, the upper cover, the hinge band, and the locking tool are integrally formed by using plastic as a material.

[0005]

The outer sheath is removed at the separation point of the 4-core cable to separate the 4-core into 2-core. This separated part is stored in the cable storage groove formed in the packing in the lower cover with the upper cover opened, the upper cover is closed and the upper and lower covers are stopped with a locking tool, and this is attached to the wall of the building, for example. Fix with an adhesive. One of the two-core cables separated in the cover is connected to the protector, and the other is connected to the telephone. The cable stored in the cover is completely sealed by the seal packing. As a result, not only invasion of dust and the like but also infiltration of rainwater and the like, the appearance is good.

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 is an exploded perspective view of a waterproof cover according to the present invention. Reference numeral 1 is a lower cover, and this lower cover 1 forms an upward peripheral edge 2, and an upward 4-core cable insertion hole 4 is formed on a 4-core cable insertion side 3 of the peripheral edge 2 to form a 2-core cable. Two lead-out cable lead-out holes 6 and 6a are formed on the lead-out side 5 so as to face upward, and hooks 8 are formed on both ends of the peripheral edge 2 so as to face outward.
It has a shape in which elastic engaging claws 7 and 7a as a locking tool in which 8a is formed are integrally formed.

Reference numeral 9 denotes an upper cover. The upper cover 9 forms a downward peripheral edge 10, and a downward 4-core cable insertion hole 12 is formed on a 4-core cable insertion side 11 of the peripheral edge 10 to form a 2-core cable. The cable lead-out side 13 has two two-core cable lead-out holes 14 and 14a formed downward, and the peripheral edge 1
0 on both sides of the middle, the hook portion 8 of the engaging claw 7, 7a,
It has a shape in which engaging edges 15 and 15a are formed as locking tools with which 8a is engaged.

Reference numeral 16 denotes a hinge band connecting the lower cover 1 and the upper cover 9 in the middle of the two-core cable drawing holes 6, 6a and 14, 14a. The hinge band 16, the lower cover 1 and the upper cover 9
The engaging claws 7 and 7a and the engaging edges 15 and 15a are plastic products integrally formed by a mold in a developed state. Reference numeral 17 denotes a lower cover seal packing housed in the lower cover 1.
4 core cable insertion groove 18 and 2 core cable separation groove 1
9 and 19a are formed in an upward Y shape.

Reference numeral 20 denotes an upper cover seal packing housed in the upper cover 9. The upper cover seal packing 20 has a 4-core cable insertion groove 21 and 2-core cable separation grooves 22 and 22a facing downward. It is formed in a letter shape.
Numerals 23 and 24 are sealing irregularities formed between the upper and lower seal packings 17 and 20, and the fitting of the irregularities 23 and 24 improves the sealing performance. The rubber forming the upper and lower seal packings 17 and 20 is a concept including both natural and synthetic rubber.

As shown in FIG. 2, the waterproof cover has seal packings 17 and 2 in the lower cover 1 and the upper cover 9, respectively.
In the state where 0 is stored and the upper cover 9 is opened, the 4-core cable 25 is divided into 2-core cables 26 and 26a, and the 4-core cable insertion groove 18 and the 2-core separation grooves 19 and 19a in the lower cover seal packing 17 are divided. The upper cover 9 is closed and the hooks 8 and 8a of the engaging claws 7 and 7a are engaged with the engaging edges 15 and 15a.
To engage and stop. At the time of this separation, the two-core cables 26 and 26a are provided with an exterior for the four-core cable 25. The waterproof cover is fixed to the wall of the building by using an adhesive or the like, and as shown in FIG.
On the CU27 side, the separated two-core cable 26a is the protector 2
8 and 26 are connected to a telephone 29. In FIG. 5, 3
Reference numeral 0 is an automatic meter reading gas meter connected to the T-NCU 27 using a two-core cable 31.

[0011]

As described above, the waterproof cover according to the present invention stores the seal packing in the lower cover and the upper cover which store the seal packing inside, and forms the Y-shaped cable storage groove in this packing. , In this, 2 4-core cables
The core cables were separated, and the separated core cables were connected to the protector and the telephone, respectively. As a result, the separated portion of the cable is completely shielded by the waterproof cover, and there is no intrusion of dust or rainwater, so there is no need to wrap vinyl tape for treatment as in the conventional case. Therefore, problems such as aesthetic problems and defective seals due to individual differences among builders do not occur.
