Description

{Multi-function power terminal for electrical wiring connection}

The present invention relates to a terminal for connecting electrical wiring, and more specifically, to a switchboard that forms a connection point between a public electric distribution network and a home electric circuit, a power outlet that receives electricity from the switchboard, and various electrical devices such as lighting fixtures. When installing facilities, it is necessary to quickly and easily connect and connect the electrical wiring required for these facilities. In particular, in addition to a stable rectification function, unnecessary electrical hazards such as ground loops, power harmonics, and current leakage are prevented. This relates to a multi-function power terminal for connecting electrical wiring that minimizes the occurrence of factors and prevents the risk of safety accidents such as electric shock and fire as well as abnormal operation or failure of electrical equipment that receives electricity from electrical wiring.

When installing various electrical facilities in a building, such as switchboards, outlets, switches, lighting fixtures, etc., it is common to wire electrical wires as an essential component in order to smoothly flow and supply power of a specified capacity.

The basic structure is that the electric wires wired within the building are accommodated and guided by separately provided protection pipes and are installed in internal spaces such as walls and ceilings, and the electric wires installed in this way are then routed to various electrical facilities, such as distribution boards, outlets, switches, and lighting. It can be used by extending it and connecting it to electrical devices such as appliances.

Therefore, when extending and connecting the basic construction electric cable to various electrical devices, there are cases where the length of the basic electrical cable must be extended depending on the site conditions, or the electric cable already connected to the electrical device, etc., and the basic construction inside the building may need to be extended. There are various cases where electric wires need to be interconnected.

Accordingly, let's briefly look at the conventional electric wire connection methods that are widely used to extend and connect the basic construction electric wires or to interconnect the electric wires of the electric device and the basic construction electric wires;

This involves removing the covering of the end of one side of the electric wire and the end of the other side of the electric line to be connected, exposing the core wire inside the electric line to a certain length, twisting and connecting the core wire of the end of the electric line on one side from which the covering has been removed and the end of the other side of the electric line by twisting, The outer surface of the re-twisted core wire connection area is finished with insulating tape to block the core islands from being exposed to the outside.

However, in the conventional electric wire connection method as described above, the core wire of the electric wire from which the covering has been removed must be twisted and connected directly using the worker's hands, and the twisted core wire connection area must be wrapped with insulation tape again to finish it. As a result, there is a problem that the connection work of the electric wire is very cumbersome and inconvenient, and in particular, there is a problem that frequently occurs when the sharp end of the core wire pierces the worker's hand and causes injury.

In addition, the insulation tape used in the conventional electric wire connection method is very weak in durability due to its material and structural characteristics, so it is easily damaged or separated, causing a short circuit, and as a result, there is a very high risk of electric shock, especially damage to the insulation tape. There is a significant lack of safety in that fire may occur at the electrical cable connection area due to a short circuit, short circuit, or overload.

Meanwhile, on the other hand, the wiring connected from the public electric distribution network to supply power to the electric appliances in the house, for example, the common electric line distributed and connected to the house through the switchboard and distribution board, usually has a power line (HotLine) with a potential of 220V, and the ground. It is grounded and consists of a neutral wire with a potential of 0V.

Therefore, in selectively variably cutting and connecting the common electric line consisting of the power line and the neutral line with the electric line of the electric equipment installed in the building, especially the electric wire of the lighting fixture, the polarity of the common electric line, such as the power line and the neutral line, may be changed due to the operator's carelessness or misjudgment. There are frequent cases where the electric wires of lighting fixtures have their polarities reversed and connected in reverse phase.

Of course, even if the common electric line and the electric line of the lighting fixture are connected in reverse phase with the polarity reversed as described above, the current flows from the power line to the neutral line due to the characteristics of the alternating current in the single-phase, two-wire system, for example, the alternating potential difference, Due to the nature of repeating the flow of current from the neutral line to the power line, there is no particular problem in the operation of lighting equipment.

However, if the polarity of the connected common electric line and the electric line of the lighting fixture do not match and are connected in reverse phase, it affects the phase of the electric signal and causes ground loops, power harmonics, and current. There is a problem in that it causes phenomena such as leakage, which increases the distortion of voltage and current waveforms, resulting in abnormal noise, vibration, overheating, and burnout of lighting fixtures.

Accordingly, in recent years, a "wire connection terminal" (Korea Patent Registration No. 1997216), previously registered at the Korean Intellectual Property Office, has been created as a way to solve the problems of the conventional electric wire connection method described above.

The "wire connection terminal" as the above-mentioned prior application registration technology is characterized by a configuration that allows the wire inserted into the wire connection terminal to easily reach the connection terminal and prevents the shaft support or fixing part from being worn or damaged.

However, the "electrical connection terminal", a previously registered technology, makes it easy and convenient to connect electric wires through a simple core wire insertion method and a sturdy finishing structure, eliminating some of the problems of the conventional manual method, such as having the worker twist and connect the core wires himself. Although it has been resolved, problems affecting the phase of electrical wiring connections, such as ground loops, power harmonics, current leakage, as well as distortion of voltage and current waveforms, and There are always existing problems with electrical appliances, such as abnormal noise, vibration, overheating, and burnout.

The present invention was created to solve the general problems of conventional terminals for connecting wires;

The purpose of the present invention is to selectively extend the wiring length of electric wires installed in a building as needed, or to extend or shorten electric wires to various electric facilities such as switchboards, distribution boards, outlets, switches, lighting fixtures, etc. It includes allowing the wiring connection work to be performed quickly and easily without unnecessary labor consumption by allowing the connection work of the electric wire to be performed by a one-touch insertion fastening method using a core wire connecting rod and a core wire fastening cap;

In particular, it has a stable rectification function and cancels out unnecessary electrical hazards such as ground loops, power harmonics, and current leakage, and by offsetting such hazards, it prevents abnormal operation or breakdown of electrical equipment and electric shock accidents. The aim is to provide a multi-functional power terminal for connecting electrical wiring that can greatly increase functionality, safety, and usage efficiency by preventing the risk of safety accidents such as fire and fire.

Therefore, specific means of the multi-function power terminal for connecting electrical wiring according to the present invention to achieve the above object include;

A noise blocking member formed of a ferrite material and having a spiral coupling groove and a connecting rod outlet hole;

An intermediate wire including a core wire connecting rod and inserted into and coupled to the spiral coupling groove of the noise blocking member;

a finishing shell formed on the outer surface of the noise blocking member to which the intermediate wire is coupled;

a core wire fastening cap that is tightly coupled to one end and the other end surface of the noise blocking member covered with the finishing protective shell and presses it by guiding the insertion of a core wire connecting rod;

This is achieved by forming a magnetic ground block that is coupled to one outer surface of the noise blocking member coated with the finishing shell.

As described above, the multi-functional power terminal for connecting electrical wiring according to the present invention performs the work of connecting the electrical lines in selectively extending and connecting the wiring length of the electrical lines as needed or selectively connecting and connecting the electrical lines to various electrical facilities in the building. This is done quickly and conveniently by using a core wire connection rod and a core wire connection cap with a one-touch insertion fastening method, which provides the effect of allowing the connection work of electrical wiring to be performed quickly and easily without consuming unnecessary labor.

Alternatively, the multi-function power terminal for connecting electrical wiring according to the present invention has a stable rectification function by means of a harmful signal blocking member and a magnetic ground block and is capable of preventing abnormal phenomena occurring at the electrical wiring connection area, such as ground loops and power harmonics. (Harmonic), which cancels out unnecessary electrical hazards such as current leakage, and prevents the risk of safety accidents such as abnormal operation or breakdown of electrical equipment, electric shock, and fire through the offsetting effect of such hazards. This provides very useful expected effects.
