Description

[Detailed Description of the Invention] The present invention relates to a telephone coupler for connecting self-employed equipment to a telephone line using a mobile telephone plug currently employed by the Telephone Corporation in Japan.

Figure 1 shows a pair of male and female connectors for plug-in telephones that are currently being used by Japan Telecommunications Corporation. A in the diagram
is attached to a wall etc. with a so-called jack,
are the two cords to be connected to the central office line.
B is the male attached to the end of the phone cord,
In other words, it is a plug. Taking this as an example of a house, jacks _A1 , _A2 , _A3, etc. are installed in each room, and the user carries one telephone and plugs it into the jack in the necessary room to make a call. can be used. At this time, jack A has sockets a ₀ , b ₀ , and c ₀ as shown in the figure.
In addition, plug B has corresponding electrodes a ₁ and b ₁
and c ₁ . Note that the electrode c ₁ is normally used while being electrically connected to the electrode a ₁ , and in this case, the electrode c ₁ also serves as a guide to prevent the plug from being inserted in the wrong direction. Now, conventionally, when installing self-employed equipment such as an answering machine, it was usually installed in parallel with a telephone, and the telephone functioned as an incoming call display (bell). Simply plugging the device into the jack was inconvenient. This is because the telephone must be unplugged from the jack, making the telephone inconvenient to use. This idea is
In such a case, it is an object of the present invention to provide a coupler that allows the use of both a telephone and private equipment such as an answering board device at the same time.

An embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view showing the relationship between the coupler C of the present invention and the members connected to the coupler C, where A is a jack connected to curve l, and B is a jack connected to a telephone set. The plug D is connected to a self-employed product such as an answering machine.

Coupler C has three electrodes protruding from its lower surface, and is configured to be fitted into each of the three corresponding sockets of the jack A, and its upper surface has three sockets arranged as a pair. There are sets. Three electrodes a ₁ , b ₁ , c ₁ of a plug connected to a telephone are fitted into sockets a ₃ , b ₃ , c ₃ of one set, and sockets a of the other set. ₄ , b ₄ , and c ₄ include the electrodes of plugs connected to self-employed equipment such as answering machines.
a ₅ , b ₅ , and c ₅ are fitted, and electrodes a ₂ , b ₂ , and c ₂ of coupler C are fitted into corresponding sockets a ₀ , b ₀ , and c ₀ of jack A, respectively. , the electrodes and guide plates of each plug B and D are inserted into each socket of coupler C, and each is used by connecting them.
The combined state is shown in FIG.

FIG. 4 is a plan view of the coupler C with the upper cover removed, and FIG. 5 is a perspective view thereof. Electrode a ₁ of telephone plug B or self-employed product plug D,
Receptacles a _{3 ′} , b _{3 ′} , a ₄ ′, which are given elasticity so as to clamp each electrode when b 1 , a ₅ , and b ₅ are inserted.
b ₄ ′ are provided corresponding to the insides of the sockets a ₃ , b ₃ , a ₄ , and b ₄ , respectively.

The receiving metal fittings a ₃ ′ and a ₄ ′ are connected by lead wires, and the receiving metal fittings b ₃ ′ and b ₄ ′ are also connected by lead wires or the like. Furthermore, the electrodes a ₂ and b ₂ of the connecting tool C are connected to the receiving metal fittings a ₃ ′ and b ₃ ′, respectively, and as a result, the electrode a ₂ , the receiving metal fittings a ₃ ′, a ₄ ′, and the electrode b ₂ and the receiving metal fitting
b ₃ ′ and b ₄ ′ are electrically integrated. 2 is a stand, and a jack A is attached to the part of the stand 2 where there is no electrode.
This is to stabilize the coupler C so that it does not wobble when the coupler C is connected to the jack A.

Note that, as mentioned above, in Japan, electrodes a and c are usually combined, and a metal fitting for electrode c is not provided, but electrodes a and c are separated and a metal fitting is provided for electrode c. It is also possible.

Because of the above structure, when connecting the coupler of the present invention to a central office line, the coupler must first be inserted into the jack of a conventional plug-in telephone connector, and then the telephone plug and self-employed equipment such as answering machines must be inserted. By inserting the plug into the telephone and connecting it as shown in Fig. 3, it is possible to connect and use private equipment in parallel with the telephone without the need for wiring work as in the past.

Also, when connected, the coupler is provided with feet, so the coupler remains stable without wobbling.
It is safe to use.
