Description

Telephone line fittings {TELEPHONE CIRCUIT PLUG}

The present invention relates to a telephone line connection mechanism, and more particularly, a plurality of trunk lines (telephones), personal communication devices (computer communication modems, etc.) and other devices (telephone operated boilers, etc.) can be connected to each other simultaneously. The invention relates to a telephone line connector.

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 4) The connecting part 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 has a standardized structure in which a modular plug which is fitted into the modular jack of the telephone is integrally formed. As another form, a structure consisting of a modular plug on one side and the other side of the main ship is used.

The telephone line connection device having a male plug and a modular plug is usually packaged when a telephone is purchased, or when a personal communication device (such as a computer with a modem) and a telephone line (eg, a telephone-operated boiler) are used. It was supplied to the user in the form.

Therefore, a conventional telephone line connection device has a standardized structure (connecting only a single telephone to a single telephone line) or an external telephone line for connecting an external telephone line to only a single device (telephone or personal communication device). It was formed as a structure that connects and another device (telephone and fax connection).

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

As a representative example in which a single telephone line is connected to a telephone or a personal communication device and other devices, there is a use case of a personal computer in which a modem is built.

This is to connect the telephone line connecting device to the main body of the telephone and then, if necessary, remove the modular plug of the telephone line connecting device from the telephone main body modular jack, and then plug it into the modular jack of the modem to be connected. After using it, I was using the Mode Lock plug again.

This replacement and installation of the modular plug of the telephone line connector into 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.

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 make it possible to simultaneously connect and connect external external circuits to general trunk lines (telephones) or personal communication devices (communication modems) and other devices by means of a single connection mechanism, thereby resulting in the inconvenience of frequent replacement installation work. It is possible to provide convenience to the user by solving the problem, and to provide a telephone line connection mechanism to improve the durability as well as to improve the durability by preventing the connection failure caused by frequent replacement installation work.

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

In the telephone line connection mechanism which can attach and detach the plug part which has four connection terminal rods with the external telephone line female connector on the wall surface,

The upper surface of the case of the plug portion constitutes a female connector having a trumpet-shaped connecting spring as a connecting means with at least two of the connecting terminal rods so as to accommodate the connecting terminal rod of another connecting mechanism. One side wall is achieved by providing a telephone line connection mechanism configured to connect a modular plug of a separate communication device by providing a modular jack connected to at least two connection terminal rods of at least the plug portion.

As the central portion, the circular through hole 343 is formed at the same position as the screw coupling hole 35 of the case 31 described above.

As shown in FIG. 3, the connection terminal rod 341 is formed with a screw hole H such that the terminal fixing screw N is coupled to an upper side thereof, and the main line is formed at one side of each insertion hole 342. 2) and when connecting the line of the modular jack 34 to the connection terminal rod 341, it is preferable to configure the reference projection 344 for guiding the line to prevent crosstalk of each line.

In addition, one side of the upper surface of the coupling plate 34, when screwing the case 31 and the coupling plate 34, the shape as shown in Figure 1 to fix the lower portion of the connecting body (J) The support 345 which takes in is comprised integrally.

Thus, look at the coupling state of the telephone line connection mechanism (1) according to the present invention having the configuration as described above and the interaction state between each component accordingly;

As shown in FIGS. 2 to 3, the connection spring 321 is first connected to the release preventing opening 322 of the case 31 while the modular plug 4 is connected to the other end of the main line 2. Fit and install, the modular jack 33 is coupled to the installation groove 311 composed of one side wall by the sliding guide 332, the main groove (2) as the fixing groove 312 formed by the other side wall After installing the connecting body (J) which accommodated one side of

As shown in FIG. 4, one side of four wires (L1, L2, E, N lines) of the main line 2 to which the Y-type connection terminal T is coupled and the connection pin 331 of the modular jack 33 are connected. The four-strand lead wire (L1, L2, E, N wire) is connected to each of the connecting terminal rod 341 of the coupling plate 331, respectively, and the connection terminal (T) by the terminal fixing screw (N) After fixing the screw to the threaded hole (H) of the connecting terminal rod (341) in the state that accommodates, after placing the coupling plate 34 completed the wire connection in this way to the bottom surface of the case 31, the coupling plate 34 of the Assembling is completed by screwing through the screwing holes 35 of the through hole 343 and the case 31 to form the plug portion 3, and the assembly thereof is completed.

At this time, when screwing the coupling plate 34 and the case 31 as described above, each terminal fixing screw of the end of the connection spring 321 is formed by the coupling plate 34 protruding with the escape prevention 322. (N) is in contact with the connection form, the connection spring 321 is such that when the connection terminal rod is inserted into the inner diameter, the connection spring 321 itself performs a stretching action and the connection is made.

Therefore, the telephone line connection device 1 according to the present invention, which is assembled as described above, is a means for connecting an external telephone line to a telephone or a personal communication device and other devices, and in particular, the aforementioned devices can be used in conjunction with each other. In this way, when connecting an external telephone line with a number of devices to be used are provided with a plurality of connection mechanism (1, 1 ') according to the present invention,

First, a connecting terminal rod 341 protruding from the plug portion 3 is inserted into a socket 5 of an external telephone line formed in a wall of a building, connected to an external telephone line, and then composed of the other end of the main line 2. Combine the modular plug (4) into a device to be used (it is always preferred to connect a telephone to use),
