Description

Wireline telephone with pushbutton switch

The present invention relates to a desk-type landline telephone which is commonly used in offices and homes, and more particularly, further installs a push button switch having the same function as a hook switch of a conventional telephone, or converts a conventional hook switch into a pushbutton switch. The present invention relates to a switch of a landline telephone, which allows an earset to be used in a conventional landline telephone.

Referring to Figure 1 and Figure 2 for a conventional landline telephone as follows. Except for the earset 200 and the push button 160 in Figure 2, when the conventional handset jack 340 is inserted into the jack socket 140 of the telephone body, a conventional landline telephone becomes. In the conventional landline telephone, when the handset 300 is lifted for the call, the hook switch (170 of FIG. 2) of the main body is raised to turn on the hook switch (SW1) of the switching switch unit 20 of FIG. do. Recently, however, a hand-free telephone using the ear set 200 shown in FIG. 2 by connecting to a small telephone is widely used. The ear set serves as a conventional phage handset, while working in the state of being plugged into an ear like an earphone. It is very convenient because you can make phone calls. The hand-free telephone is generally made small and sold by combining the earset, but the earset could be used by being connected to the jack socket of the conventional telephone body instead of the gripped handset of the conventional telephone. In FIG. 2, when the earset is connected to the conventional telephone, the gripper handset 300 of FIG. 2 is put down to turn on the hook switch during the call, and the gripper handset is put up so that the hook switch is turned off after the call. This is very cumbersome and requires a convenient switching method of connecting and boiling a phone call without having to lift and release a phage handset. In addition, the conventional telephone has only one jack 140 that can be plugged into the handset, so if you want to use the earset in the conventional telephone, the conventional phage handset had to be removed. Therefore, in order to use the handset while using the earset, the handset had to be pulled out and connected again to the gripper handset. Therefore, there is a need for a device capable of selecting a convenient one at any time without replacing the handset as needed in a wireline telephone.

In view of the above, the present invention is capable of making a call without connecting the earset to the conventional telephone without turning on / off the high hook switch, and connecting the earset and the conventional gripper handset to a wired telephone to selectively use the telephone. It is an object to provide a device.

To show a perspective view of a landline telephone having a pushbutton switch.

In Figure 1, the ring tone generator 10 is ringing the telephone ring until the switch is switched on when the call from the outside, the phone ring is stopped when the switch is switched on. The switch 20 of Figure 1 is conventionally provided with only one hook switch (SW1) is a telephone user to pick up the phone (170 in Figure 2) to lift the grip type handset (300 in Figure 2) for phone calls to switch up Turn on the hook switch (SW1) of the switch unit to switch the telephone circuit to a state that can be called, and when the telephone is finished and the handset is finished, the hook is pressed down by the weight of the handset and the hook switch (SW1) of the cutoff switch unit is turned off. Put the phone circuit to the call waiting state. In the present invention, by connecting the push button switch (SW2) in parallel with the conventional switch switch (SW1) in the switching switch unit is configured to switch the phone circuit unit to the available state when the switch is on, push button switch of Figure 1 In the case of actually mounting (SW2), a push button is further added to the hook 170 of the mounting unit 130 as shown in the upper part of the phone body of FIG. Pressing the pushbutton 160 mounted on the telephone body of FIG. 2 once, the pushbutton switch SW2 of FIG. 1 is on, and pressing the pushbutton 160 once again operates the pushbutton switch SW2 to be off. do. This means that the telephone can be simply switched from the call waiting state to the available state and from the available state to the call standby state by pressing the push button without having to lift and release the conventional phage handset for the call. The telephone circuit section 30 of FIG. 1 is no different from the conventional wired telephone and its configuration and operation. However, if the earset is used instead of the gripping handset or the earset is used with the gripping handset, some modifications to the impedance matching may be necessary. The handset unit 40 of FIG. 1 shows a conventional handheld handset (300 in FIG. 2), but the present invention has an earset (200 in FIG. 2) which is capable of making a phone call in the ear instead of a conventional handheld handset (300 in FIG. 2). ), So that the handset 40 of FIG. 1 shows the ear set (200 in FIG. 2) instead of the conventional gripper (300 in FIG. 2).

As shown in FIG. 2, the conventional telephone is provided with only one connector jack socket for connecting the handset to the telephone circuit unit, and when the ear set is to be used instead of the gripped handset, the gripped handset can be removed and the earset is connected. Therefore, in the present invention, an additional jack socket (150 in FIG. 4) connected in parallel with the conventional handset jack socket (140 in FIG. 4) is connected to the telephone circuit unit to simultaneously connect the gripper handset and the earset to the telephone main body. It can be selectively used, which is shown in the transmitter 40 of FIG. In Figure 3, when the user wants to make a telephone call, the conventional handset (SPK1, MIC1) is turned on when the hook switch (SW1) of the switching switch unit 20 is turned on when the conventional handheld handset is picked up and lifted by the handheld handset. If you press the pushbutton (160 in Fig. 4) by selecting the earset with the gripping handset intact, the pushbutton switch (SW2) is turned on and the conversation via the earset (SPK2, MIC2) Will be able to. Impedance mismatch that may occur by adding a jack can be easily solved by modifying the telephone circuit unit 30.
