Description

Distribution cable outlet terminal corrosion protection device {APPARATUS FOR PREVENTING RUST OF CONNECTING TERMINAL OF POWER HOLE CABLE FOR POWER DISTRIBUTING}

The present invention relates to a terminal corrosion prevention device of a power distribution cable connection terminal, and more particularly, to prevent the rainwater from penetrating into the terminal of the cable connected to the distribution panel to prevent the accident of corrosion and leakage of the terminal in advance. The invention relates to a distribution power cable cable connection terminal corrosion protection device.

Commonly used switchboards lack watertightness and airtightness, which causes leakage due to leakage in rainy weather and inadvertent operation of switches in the vicinity of switchboards, resulting in power outages and safety accidents resulting in the sudden shutdown of facilities. In addition to the accident of the facility, problems such as causing a disruption in productivity have been raised.

In addition to the problems described above, when the conventional switchboards are installed and used in a selected place, various chemical gases or foreign substances existing in the atmosphere penetrate into the switchboard and accumulate and are connected to various switches, display lamps, indicators, and wires installed in the switchboard. Sparks or short circuits caused by unsafe contacts on the back and the air supply shorten the replacement time due to a sudden decrease in lifespan, resulting in a loss of construction costs and a decrease in the operation rate of the equipment.

On the other hand, the electricity drawn into the building must be supplied indoors through the distribution panel.

In general, switchboards are provided with switches for each branch circuit in a branch that is separated from the trunk line in the indoor wiring. Each office in a house or building receives a predetermined power supply from the switchboard. It is a device that distributes / blocks electric power according to various loads such as electric light, electric heat, and power load of factories.

A conventional distribution panel is composed of a cabinet and a base panel mounted inside the cabinet and electrically connecting an incoming cable and one or more lines of supply cables.

The cabinet is composed of a cabinet body opened toward one side and a cover for opening and closing the inside of the cabinet body. In the cabinet body, a wiring hole through which an incoming cable and a supply cable pass is formed.

The base panel receives power from an inlet cable and distributes it to a supply cable, a substrate fastened to a cabinet with bolts, etc., a circuit unit mounted on the substrate and electrically connecting the inlet cable and the supply cable to distribute power. And breakers that block the incoming cables and circuitry.

The incoming cable and the supply cable are inserted into the protection tube, respectively, to prevent disconnection and leakage due to impact from the outside, and the ends of the protection tube are respectively coupled to the wiring hole of the cabinet. In other words, the protection tube is finished in the wiring hole of the cabinet and the incoming cable and the supply cable are connected to the circuit part.

However, the distribution panel according to the prior art has the following problems.

Rain and moisture can penetrate the protective tube of the inlet cable and supply cable of the distribution panel, indoors or outdoors. However, in the conventional distribution panel, since the rainwater and moisture that penetrate the inside of the cabinet cannot be removed, there is a possibility that an electric leakage accident due to rainwater and moisture may occur.

The present invention is to solve the above problems, the distribution power port cable connection terminal that can prevent the short circuit accident due to rain by preventing rainwater from penetrating the electrical circuit portion such as the terminal connected to the switchboard through the cable. The purpose is to provide a corrosion protection device.

Distribution apparatus for preventing power distribution cable connection terminal according to the present invention for achieving the above object, a plurality of leakage blocking spheres are connected in series with each other surrounding the periphery of the cable connected to the switchboard; It includes a cylindrical closure cap coupled to the upper opening of the leakage blocking sphere disposed at the top of the plurality of leakage blocking spheres, the plurality of leakage blocking spheres are small diameter portion, the connecting portion is gradually enlarged diameter formed on the lower portion of the small diameter portion, The lower diameter of the connection portion is formed in a cylindrical shape having a larger diameter than the small diameter portion, the skirt is integrally formed downward inclined toward the circumference portion, the leakage blocking opening disposed on the bottom side is outside the switchboard While being supported on the upper surface of the insulator to be installed, it is characterized by wrapping the terminal connected to the insulator.

According to the power distribution cable outlet terminal corrosion protection device according to the present invention, the rainwater flowing along the cable does not penetrate the terminal for the connection of the cable can prevent the terminal corrosion and short circuit accidents.

As shown in FIG. 1 and FIG. 2, the apparatus for preventing corrosion of a power distribution cable connection terminal according to the present invention is such that rainwater does not penetrate into the terminal 3 of the cable 2 introduced into or withdrawn from the switchboard 1. The terminal 3 is supported by the insulator 4 provided outside the switchboard 1.

The power distribution cable outlet terminal corrosion protection device according to the present invention, the first to third leakage blocking openings (10, 20, 30) and the closing cap surrounding the cable (2) and the terminal (3) and insulator (4) It consists of 40.

The first to third leakage blocking holes 10, 20, and 30 have the same structure, but are stacked in series, and the larger the cross-sectional area is formed as the rainwater is disposed at the lower side as the rainwater is led away from the terminal 4. do. For convenience of description, the first to third leakage blocking holes 10, 20, and 30 are arranged in order from the top.

The first leakage blocking opening 10 has a cylindrical structure in which both sides (both upper and lower sides based on the installation state) are opened, and the small diameter portion 11-the connection portion 12-the large diameter portion 13-the skirt (from the top) 14) is integrally formed.

The small diameter portion 11 is a portion fitted into the interior of the closing cap 40 may be a screw thread formed on the outer peripheral surface.

The connecting portion 12 is gradually expanded in diameter as the diameter goes downward to integrally form the large diameter portion 13 at the lower portion of the small diameter portion 11.

The large diameter portion 13 is a portion connecting the first and second leakage blocking holes 10 and 20 by inserting the small diameter portion 21 of the second leakage blocking hole 20 to be described later.

The skirt 14 is integrally formed inclined downwardly at the connecting portion 12 to guide the rainwater flowing down the surface of the closing cap 40 and the small diameter portion 11 away from the terminal 3.

The second leak stopper 20 and the third leak stopper 30 are the same as the first leak stopper 10, the small diameter parts 21 and 31, the connection parts 22 and 32, and the large diameter parts 23 and 33. ), A skirt having a skirt (24, 34), and is coupled in series to the lower portion of the first leak stopper (10).

Chain coupling of the first to third leak blocking blocks (10, 20, 30) may be made by the fitting method of the large diameter portion 13, 23 and the small diameter portion (21, 31) facing each other, the first to third The three leakage blocking holes 10, 20, and 30 have a larger cross-sectional area toward the lower third leakage blocking hole 30, so that the large diameter portions 13 and 23 on the upper side surround the small diameter portions 21 and 31 on the lower side. Form. According to such a structure, since the large diameter portions 13 and 23 surround the lower small diameter portions 21 and 31 from the outside, the rainwater flowing down from the upper portion of the second and third leakage blocking holes 20 and 30 is disposed. It does not penetrate inside.

Through the above structure, the first to third leakage blocking openings 10, 20, and 30 form a tube to seal the cable 2 and the terminal 3 to the outside, and may prevent the penetration of rainwater. When rainwater flows into the first to third leak blocking holes 10 and 2030, the rainwater inside the large diameter part 33 of the third leak blocking hole 30 is discharged to the outside so that the rainwater is discharged to the outside. A plurality of drainage holes 35 are formed. The drain hole 35 is formed to be inclined downward toward the outside so that the water inside is quickly drained, but the outside water does not penetrate the inside.

Closing cap 40 is to seal the upper opening of the first leakage block 10, made of a rubber material of elastic force so that rainwater does not penetrate through the cable (2) and a thread is formed on the inner peripheral surface 1 may be screwed to the small diameter portion (11) of the leakage blocking port (10).

The closing cap 40 is pointed toward the upper end so that rainwater down the surface of the cable 2 is guided toward the circumference.

According to the structure described so far, the first to third leakage blocking holes 10, 20, 30 and the closing cap 40 are applied to the existing cable 2 because both sides are opened only for the wiring of the cable 2. In order to remove the cable (2) from the switchboard (1), this operation can be cumbersome, so the first to third leak breaker (10, 20, 30) and the closing cap 40, respectively, the cable (2) It is made of a structure that can wrap the cable (2) in the state not separated in (1).

The split structure of the third leakage blocking sphere 30 will be described as an example. As shown in FIG. 3, the third leakage blocking hole 30 is divided into two 30-1 and 30-2 of right and left symmetry. One side facing each other is foldably connected through the hinge 36, and the free end of the other side is fixed through the fastener 37. Since the small diameter portion 31 will be inserted into the second leakage blocking hole 20, the fastener 37 is fastened only to the large diameter portion 34.

In such a structure, the third leakage blocking device 30 is fastened by wrapping and fixing the protrusion 4a of the insulator 4 on the lower portion of the third leakage blocking device 30 so as to be firmly fixed to the insulator 4. A portion 38 may be formed.

Since the first and second leakage blocking holes 10 and 20 and the closing cap 40 are also formed in the same structure as the third leakage blocking hole 30, detailed descriptions and drawings will be omitted.

Distribution of the power distribution cable connector terminal corrosion protection device according to the present invention is as follows.

Rainwater flows down to the switchboard 1 side along the surfaces of the cable 2 and the first through third leak stops 10, 20, 30 and the closing cap 40.

The rainwater coming down the surface of the cable 2 meets the finishing cap 40.

Since the closing cap 40 is elastically in close contact with the cable 2, the rainwater coming down the cable 2 does not penetrate into the closing cap 40 and flows to the surface of the closing cap 40.

The rainwater flowing along the surface of the closing cap 40 falls freely into the skirt 14 of the first leakage blocking opening 10 and then to the skirt 24 of the second leakage blocking opening 20 along the skirt 14. Free fall.

Rainfall that falls on the skirt 24 of the second leakage blocking hole 20 falls freely into the skirt 34 of the third leakage blocking hole 30, flows to the circumference along the skirt 34, and falls. At this time, since the location of the rainwater falling from the third leakage blocking port 30 is far from the terminal 3, the rainwater falling into the switchboard 1 does not penetrate to the terminal 3 side.

Some storms may hit the large diameter portions 13, 23, 33 of the first to third leak stops 10, 20, 30 directly, and this storm may be large diameter portions 13-skirts 14-large. The neck 23 falls down along the path of the skirt 24, the large neck 33, and the skirt 34.

On the other hand, although rainwater will not be collected on the terminal 3 side by blocking the penetration of rainwater directed toward the terminal 3 as much as possible, some rainwater may penetrate into the first to third leakage blocking holes 10, 20, 30. This rainwater may be drained to the outside through the drain hole 35 so as not to collect in the first to third leakage blocking holes 10, 20, and 30.
