The present invention relates to a direct station selection (DSS) for expanding a key phone terminal, and in particular, in connecting a DSS to a key phone terminal or connecting a plurality of adjacent DSSs without using a separate connecting member, a latching structure such as a hook type. The present invention relates to a DSS for expanding a phone terminal using a structure and a hook insertion hole.

The key phone terminal has various additional functions including an exchange function, and in order to expand the functions of the key phone terminal, it is necessary to additionally connect a separate DSS having a plurality of buttons to the key phone terminal.

Fig. 1 shows a DSS for expanding a conventional phone terminal. As shown in Fig. 1, in the related art, when connecting a DSS to a key phone terminal or connecting a plurality of DSSs, the key member is held between a key phone terminal and a DSS or between a plurality of DSSs by connecting a connection member 102 manufactured by pressing. Alternatively, a screw was inserted into the screw hole of the DSS to connect with the connecting member.

According to the prior art, the connection member has to be manufactured and installed separately, thereby increasing the number of parts and increasing the manufacturing cost. In addition, in order to connect the DSS to the key-phone terminal or to connect a plurality of adjacent DSSs to each other, screw fastening was required, so the user had to bear the inconvenience of screwing or dismantling.

The present invention is devised to solve the above-mentioned problems of the prior art, and provides a DSS for expanding a key phone terminal that can easily connect a DSS or a plurality of adjacent DSSs without using a separate connecting member. It aims to do it.

According to the present invention, the DSS for extending a key phone terminal for use in connection with a key phone terminal extends outward from the top with a button, a bottom portion opposite to the top, and one end of the bottom portion from the inside of the bottom portion. And a first latching structure integrally formed with the bottom portion, and a second latching structure formed on the bottom portion and disposed opposite the first latching structure. With this configuration, since the first latching structure of the DSS can be latched to the second latching structure of the adjacent DSS, a plurality of adjacent DSSs can be easily connected without a separate connecting member.

Preferably, the first latching structure of the DSS is a hook type structure having a hook portion at an outer end thereof.

Also preferably, the second latching structure of the DSS is a hook insertion hole.

In addition, the hook portion of the DSS is detachably coupled to the hole formed in the bottom portion of the key phone terminal.

The present invention latches and engages a first latching structure (eg, hook-type structure) integrally formed at the bottom of a DSS with a second latching structure (eg, hook insertion hole) formed at the bottom of a keyphone terminal or at the bottom of an adjacent DSS. As a result, the DSS can be easily detached without using a separate connecting member. Hereinafter, an embodiment of the present invention for expanding the function of a key phone terminal by combining a plurality of adjacent DSS will be described in detail.

FIG. 2A is a plan view showing a top 202 of a DSS according to an embodiment of the present invention, and FIG. 2B is a bottom view showing a bottom portion 204 of a DSS according to an embodiment of the present invention.

As shown in Figure 2A, there are a plurality of buttons 212 on top of the DSS. DSS can have multiple buttons with different functions, such as a divert button for a call, a hold button for a call, a CO line occupancy button, and an extension occupancy button. As can be seen from Figures 2a and 2b, the present invention provides a hook-like structure that extends outwardly from the inside of the bottom 204 of the DSS past one end of the bottom to provide a connection structure for expanding the functionality of the keyphone terminal. 206 is integrally formed with the bottom, and a hook insertion hole 210 is provided at the bottom 204 of the DSS opposite the hook-shaped structure 206. The outer end of the hook-shaped structure 206 is provided with a chamfered hook portion 208. The hook portion 208 of the DSS can easily connect two adjacent DSSs to each other by latching the hook insertion hole 210 formed in the bottom 204 of the adjacent DSS 200.

FIG. 3 is a schematic diagram illustrating an operation of rotating the DSS about an upper edge portion of the DSS to couple the hook portion 208 to the hook insertion hole 210. 4 is an enlarged view illustrating a portion A of FIG. 3 in an enlarged manner. As shown in Figures 3 and 4, the upper edge portion 216 of the DSS 200 is in close contact with the upper edge portion 218 of the adjacent DSS 200 ', and then the upper edge portion of the DSS 200'. Rotate the DSS 200 with 218 as the axis of rotation. Due to the rotational movement of the DSS, as shown in FIG. 5, the chamfered hook portion 208 slides along the inclined surface inside the hook insertion hole 210 and is fitted into the hook insertion hole 210.

6 is a coupling diagram in which DSSs are connected to each other according to an embodiment of the present invention. A plurality of DSSs can be easily detached by rotating both upper corner portions of the DSSs about an axis to fit the hook portions of the DSSs into the hook insertion holes of the adjacent DSSs.

On the other hand, another embodiment of the present invention is to extend the function of the key phone terminal by connecting the hook portion of the DSS to the hook insertion hole of the key phone terminal. In another embodiment of the present invention, a hook insertion hole (eg, a square hole), such as the hook insertion hole 210 illustrated in FIG. 2B, is installed at the bottom of the key phone terminal.

In another embodiment of the present invention, the key phone terminal can be expanded by connecting a plurality of DSSs to each other and connecting the hook portion of the outermost DSS of the plurality of connected DSSs to a hook insertion hole formed at the bottom of the key phone terminal.

The present invention has been described with reference to preferred embodiments, which are merely exemplary, and those skilled in the art will understand that various modifications can be made therefrom without departing from the scope of the present invention.

The present invention can reduce the number of parts and the cost compared to the prior art adopting the connection structure for fastening the separate connection member with a screw. In addition, the user does not need to tighten or loosen the screws with a separate tool, and only by fastening the hook portion formed integrally with the DSS to the hook insertion hole of the adjacent DSS or the hook insertion hole of the keypad, the function of the key phone terminal can be expanded. Because it can be, there is an advantage that the handling is convenient.
