Description

Telephone line fittings {TELEPHONE CIRCUIT PLUG}

The present invention relates to a telephone line connecting device, and more particularly, to a telephone line connecting device configured of a telephone line connecting device configured to simultaneously connect a single external telephone line to a plurality of communication devices.

In general, a telephone line connecting device is used as a means for connecting a telephone with an external telephone line provided in a wall of a building, and such a telephone line connecting device is an external telephone line (usually four The plug portion is formed to protrude four connecting terminal rods so as to be pin-coupled to the female connector having a hole), and the other side of the main line is integrally formed with a modular plug fitted into the modular jack of the telephone. As it is standardized and used,

Such a telephone line connection device having a plug portion and a modular plug is usually packaged when a telephone is purchased or a personal communication device (such as a computer with a modem) and other equipment (such as a telephone-operated boiler) that are used by connecting a telephone line. It was supplied to the user in the form.

Therefore, the conventional telephone line connection mechanism is formed as a standardized structure (one-to-one connection structure) that can connect only one external telephone line to only one device (telephone or personal communication device).

On the other hand, in recent years, due to the rapid economic development, telephone line distribution has become popular not only in general offices but also in families, and accordingly, personal communication devices and devices operated by telephones have been put into practical use.

A typical example in which a single telephone line is connected to a communication device as described above may be a use case of a personal computer having a modem.

This is to connect the telephone line connecting device to the main body of the phone, and then, if necessary, remove the modular plug of the telephone line connecting device from the modular jack of the telephone main body, and then plug it into the modular jack of the modem to be connected. After using it, I had to reinstall the modular plug back to the phone base to use the phone.

This replacement and installation of the modular plug of the telephone line connection device to the necessary equipment was a significant inconvenience in busy daily life.

Such frequent repetitive replacement installation work deforms (or damages) the modular plug of the connecting device and the part to which the modular plug is coupled, thereby shortening its lifespan and causing problems of deterioration in durability.

In addition, although the connecting mechanism consisting of a female connector that is in contact with the connecting terminal rod on the upper surface of the plug portion is used, this is also a form of connecting a single modular plug in a series of direct connection because the wiring structure is limited, a plurality of communication devices In case of using the above problem, the above-mentioned problems still exist.

Therefore, the present invention was devised to solve the general problems of the aforementioned conventional telephone line connection mechanism,

The purpose of the present invention is to enable users to connect external whole circuits to general public telephones (telephones) and other equipment at the same time by a single connection mechanism, thereby eliminating the inconvenience caused by frequent replacement and installation work. In another aspect, the present invention provides a telephone line connection mechanism that prevents connection defects caused by frequent replacement installation work, thereby improving durability and increasing use efficiency.

As a specific means of the present invention for achieving the above object;

In a telephone line connecting mechanism comprising a plug portion coupled to a terminal plate having four connecting terminal bars and a case having a female connector serving as a connecting means between other connecting mechanisms as a means for connecting an external telephone line to an individual communication device.

The installation grooves are formed by one side wall and the other side wall of the case, and at least two wires are connected to the connection terminal rods, and a pair of branch wires having a modular plug are divided and coupled, and the inner wall of the case has a locking protrusion. A pair of elastic coupling spheres are formed, and the terminal piece is provided with a telephone line connecting mechanism configured to form a fixed piece such that the case and the terminal plate are coupled by the elastic coupling sphere and the fixed piece.
