Description

Wire connecting device and wire connecting method using same {Wire Connecting Device and Wire Connecting Method Using the Device}

The present invention relates to a wire connection device for use in indoor and outdoor electrical construction, in particular lighting wiring construction, outlet wiring construction, and a wire connection method using the same.

Wires drawn from the switchboard for lighting-switch wiring and outlet wiring of various buildings such as office buildings, factories, houses, etc. In the wiring metal box, which is called a full box, junk box, switch box, outlet box, outlet box, etc., the positive wire (+ wire), the negative wire (-wire) and the ground wire which extend from the switchboard are designed for switches, lights, It is connected to the positive wire (+ wire), the negative wire (-wire) and the ground wires of the outlet.

The connection of electric wires in such various metal boxes for wiring is usually done by peeling off the sheaths of the wires to be connected and twisting the wires together, then taping them with insulating tape or shielding them using a high-cone type wire connector. This is commonly used.

However, the method of stripping the ends of the wires, twisting and connecting the exposed spirals and then taping them or shielding them using a wire connector is time consuming and wasteful of wires, and various attempts have been made to modularize them.

Patent No. 10-0635789 (hereinafter referred to as “prior art 1”), published October 19, 2006, discloses a modular device for wire connection. 1 to 3 of the prior art 1 discloses a modularization device having a body portion made of an insulation containing a wire connection module connected by a copper plate.

However, the modularization device disclosed in the prior art 1 adopts a configuration in which a module designed and manufactured separately is used according to the number of wires to be wired in each wiring metal box, a control circuit, or the like when designing a building or a house. Since various types of modules must be designed independently for the metal box, there is a problem in that the manufacturing cost of the modules becomes expensive.

In addition, if the wiring to be connected in the metal box for wiring is complicated, such as wiring for connecting a plurality of lights and switches, the operator prepares a complicated wiring diagram for the connection of the wires, and mounts a specific module for each metal box for the wiring. Since the wires corresponding to the respective wire receiving grooves must be connected, the use of the module makes it difficult to work, so it is difficult to expect a substantial reduction in the working time according to the use of the module.

On the other hand, Patent No. 10-0720980 (hereinafter referred to as Prior Art 2) published on June 4, 2007 discloses a power distribution connection device having a simplified configuration of the above-described wire connection module. As shown in Figures 1 to 5 of the prior art 2, the power distribution connector of the prior art 2 is a power connector for connecting the electric wire to the outer member which is an insulator formed by separating the power receiving groove and the ground receiving groove And the installation of a grounding connection port, elastically inserting and fixing the power line and ground wire, and when the connection is wrong, it has disclosed a configuration having a pressing portion for separating the spring portion and the wire.

However, prior art 2, like the prior art 1, basically separates the power receiving groove and the ground receiving groove in a single connection device according to the concept of using a single connection device in a metal box for wiring, and arranges the receiving grooves in parallel. This is designed to connect two pairs of four wires side by side including the ground wire.

As described later through the embodiments of the present invention, such a unified connection device has a disadvantage that it is difficult to apply to the connection of various wires generated in the actual light and switch connection wiring. That is, the number of wires to be connected varies every time according to the number of lights and switches to be wired, and the terminals in the housing must be separated from each other so that wires having different polarities are separated from each other. When the number of wires to be wired is required, and a large number of wires are wired, as in the prior art 1, a complicated connection device having a plurality of divided receiving grooves faces a difficulty of wiring with reference to the wiring drawings.

In addition, even in the case of designing with a small number of general-purpose connecting devices for use in various cases, there are frequently 2-4 wires to be connected together with the same polarity as in the light-switch connection. If the wires to be connected together and the configuration of the connection device (arrangement of accommodation grooves, connection terminals, etc.) do not match, the connection device cannot be used or there are many accommodation grooves that are not used in the wire connection device. Cause.

In addition, in the prior art 2, the receiving grooves for the power supply and the ground for the connection device are arranged side by side in two rows, but the wires to be wired are not made side by side in two directions, so that the wires must be extended in the opposite direction for the connection of the same polarity wires. If the design is not as expected with the designed connection equipment, the wiring work becomes complicated.

In addition, since the connecting device according to the prior art 2 is formed integrally with the receiving groove for the power supply and the ground receiving groove divided into two according to the polarity, the size of the connecting device becomes large, if you want to place it in two or more metal box for wiring It also has a disadvantage that it is difficult to install in a metal box for wiring having a constant standard.

In addition, although the prior art 2 proposes a method of using an elastic spring in the wire receiving groove by improving the structure of the prior art 1, in consideration of the ease of insertion and removal, the wire inserted into the receiving groove by the bent portion of the spring Although a configuration is selected to be sexually supported, such a structure may have a concern that the wire may be separated from the receiving groove even if a small force is applied to the inserted wire.

The present invention is a wire connection to replace the conventional tape connection method or the wire connection method using a wire connector in the lighting wiring work, the outlet wiring work for connecting the lighting lamp and the switch in the electrical work, in particular the metal box for wiring. It is an object of the present invention to provide a wire connection device having a structure that is easy to use by anyone who understands a wiring circuit as well as those who are familiar with the conventional wire connection method while providing a device.

Another object of the present invention is to provide a wire connecting device having a structure that is simple in structure to reduce the manufacturing cost and can effectively prevent the departure of the wire after connecting the wire.

It is still another object of the present invention to select a minimum size corresponding to the number and location of wires of the same polarity to be connected together in a metal box for wiring, so that a small number of wires can be easily arranged in a single metal box for wiring. It is to provide a connection device and a wire connection method.

According to the present invention, the connection of the wires in the wiring metal box is classified into two wires having the same polarity, such as two wires, three wires, and four wires. It starts from being done in a way. In addition, according to the number of lights for lighting and the number of switches for dividing and blinking in buildings or houses, the polarity is the same in each metal box for wiring and the number of wires to be connected together varies. In addition, even in a single metal box, there are wires that must be connected together because they have the same polarity and different polarities. Therefore, it is difficult to integrate them into a single wire connection device. As in the connection method, it becomes more practical and economic to provide a small variety of wire connection devices in sets so that a plurality of wire connection devices can be used depending on the number of wires to be connected together. Therefore, in order to replace the existing taping cable connection method or wire connection method using wire connector in indoor and outdoor electric works, wire connection devices of various specifications for frequently used wire connection such as 2 wire, 3 wire, 4 wire are used. By providing a set, the connection device can be selected according to the number of wires to be connected by the operator so that the wire connection device can be used in a manner similar to the existing wire connection and taping methods.

In order to achieve these objects, the present invention provides a housing having at least two receiving grooves partitioned by at least one barrier connected to the other side wall extending from one side wall, the connecting portion installed at the top of the housing and the connecting portion of the housing. A connecting terminal having at least two contacts each extending into at least two receiving grooves, at least two fixing springs installed in each receiving groove of the housing to face the contact and having a fixed end and an arc-shaped elastic portion, and a housing; Consists of a cover fastened to the upper end of the cover to provide a wire connecting device that can complete the connection of the wires simply by inserting the wires to be connected together between the contact and the fixed spring of the housing.
