Description

Main phone / extension phone connection structure

The present invention relates to a telephone, and more particularly, to a structure for connecting an extension telephone in the main telephone.

In general, the telephones in the office are installed and used together with the extension telephones for the internal exchange in addition to the main telephones.If the main telephones and extension telephones are not bundled together, they are inclined to one side by the user's frequent touches. When the main telephone and the extension telephone are installed together, the main telephone and the extension telephone are connected to each other as a fastener together with the bracket.

The present invention is to solve the inconvenience, inconvenience, and inefficiency of the work by connecting the main telephone and the extension telephone to each other as a separate fastener with the bracket as described above.

1 is a view showing the appearance of a general main telephone and a main telephone, and FIG. 2 is a connection state of the main telephone and the extension telephone of FIG. 1, and FIG. 3 is a perspective view showing the bracket structure of the present invention, and a and 4 of FIG. b is the AA 'line sectional drawing and the B-B' line sectional drawing of FIG.

As shown therein, the present invention has a pair of first guide rails 10 and 10A having a predetermined interval therebetween to be opened in one direction on the bottom surface of the main telephone 100, and the bottom of the extension telephone 200. Two pairs of the second guide rails 20 and 20A and the third guide rails 30 and 30A are formed on the surface thereof and symmetrically with respect to the first guide rails 10 and 10A.

In addition, a pair of hooks A 40 and 40A are formed between the first guide rails 10 and 10A with a predetermined distance therebetween, and a hook B between the second guide rails 20 and 20A. 50 is formed between the second guide rails 20 and 20A, and the third guide rails 30 and 30A, which are symmetrical, are spaced apart from each other in the same manner as the first guide rails 10 and 10A. A pair of hooks C 60 and 60A having a

In addition, a plate-shaped bracket 70 having a predetermined area is provided separately from the phone, wherein the bracket 70 has the hooks A, B, C 40, 40A and 50 as shown in FIG. Clamping holes A, B, C (71) (72) (73) are formed so that the 50A, 60 (60A) can be fitted.

The following describes the assembly process of the present invention configured as described above.

First, the worker inverts the main telephone 100 and pushes the bracket 70 between the first guide rails 10 and 10A. When the bracket 70 is pushed between the first guide rails 10 and 10A in this way, the bracket 70 slides along the first guide rails 10 and 10A and the first guide rail 10. The hook holes A and B 71 and 72 of the bracket 70 are fitted into a pair of hooks A 40 and 40 A provided between the 10 A portions so that one side of the bracket 70 is connected to the main telephone 100. It is fixed to the bottom surface of the other side protrudes out of the main telephone (100).

In this state, the worker inverts the extension telephone 200 again, and the second guide rails 20 and 20A formed on the bottom surface of the extension telephone 200 protrude outward of the main telephone 100. By engaging the other side of the 70, the hook hole C formed on the other side of the bracket 70 on the hook B 50 formed in the middle portion between the second guide rails 20, 20A of the extension telephone 200 ( 73) is fitted. And the main telephone 100 and the extension telephone 200 is connected.

In addition, the brackets are assembled by pushing the brackets to the third guide rails 30 and 30A formed on the bottom surface of the extension telephone 200 and the bottom guide rail of another extension telephone 200 to be additionally installed in the same manner as described above. By doing so, you can connect as many extension phones as you want.

The present invention, as described above, by connecting the main telephone and the extension telephone with a bracket without a separate fastening is not only easier to work but also has the effect of increasing the speed and efficiency of the work.

The present invention is to provide a main phone / extension phone connection structure to more easily connect the main phone and the extension phone.
