Description

[Detailed description of the invention] This invention uses a circuit board, a transmitter, and a handset as common parts, and has two types of telephones: one in which the circuit board is mounted on the base set, and one in which the circuit board is mounted in the handset. This invention relates to a handset/receiver cord (curl cord) that allows connections between parts to be made without increasing the types of connecting cords.

Figures 1a and b show two types of telephones: one in which a circuit board connected using a conventional handset cord with female terminals on both ends is mounted on the base set, and one in which the circuit board is mounted in a handset. FIG. 3 shows a perspective view of a connection state between parts in a telephone.

In the figure, 1 is a conventional handset cord, 2 ₁ , 2
₁ ′, 2 ₈ , 2 ₉ are female terminals, 3 ₄ , 3 ₅ , 3 ₆ , 3 ₇ , 3 ₁₀
is a male terminal, 4 is a circuit board, 5 is a transmitter, 6 is a receiver, 7 is a linker, 8 is a machine string, 9 is a connection string A,
10 indicates a connecting string B.

In Fig. 1a, one female terminal ₂₁ of the handset cord 1 is connected to the male terminal ₃₄ installed upright on the circuit board 4 in the base set, and the other female terminal ₂₁ ' is connected to the transmitter in the handset. male terminal 3 ₅ of the receiver 5 and the receiver 6,
3 _{and 6} respectively. Also, machine string 8
The female terminal ₂₈ of is connected to the male terminal ₃₄ of the circuit board 4, and the ringer 7 is connected to the circuit board 4 using a connecting string A9 having female terminals ₂₉ at both ends.

FIG. 1B shows the connection when the circuit board 4 is mounted on a handset using the handset cord 1, circuit board 4, transmitter 5, handset 6, ringer 7, and machine cord 8. The following points are different from the case shown in Fig. 1a. One extra connection string A9 is required for connecting the transmitter 5, the receiver 6 and the circuit board (one for the ringer is not needed). In order to connect the handset string 1 and the machine string 8, a connecting string B10 having male terminals ₃₁₀ at both ends is required.

Therefore, when using the conventional handset string 1,
The disadvantage is that the telephone cannot be configured using only the same parts for two types of telephones, and the structure of the parts and the assembly of the management telephone become complicated.

In order to solve the drawbacks of the conventional handset and receiver, the present invention is characterized in that one end of the conventional handset cord has a female terminal shape and the other end has a terminal shape, and the purpose is to connect the circuit board to the base set. To configure a telephone by using the same parts for connection between parts in two types of telephone set and a telephone mounted in a handset, and to simplify manufacturing and management of parts and assembly of the telephone set.

The present invention will be explained based on the drawings.

Figure 2a is a perspective view of the wiring state in which the circuit board mounted on the base set and the transmitter and receiver in the handset are connected by the handset cord of the present invention, and Figure 2b is a perspective view of the wiring state in which the circuit board mounted on the base set is connected to the transmitter and receiver in the handset. A perspective view of a wiring state similar to that in Figure A when a circuit board is mounted is shown. Figures 4a and 4b show the female terminal and male terminal of the handset cord of the present invention.

In the figure, the same symbols as in FIG. 1 indicate the same parts. In the figure, 11 is the handset cord of the present invention, 2
₁₁ indicates a female terminal, and 12 indicates a male terminal for the transmitter/receiver string.

In FIG. 2a, the portion connected to the circuit board 4 is exactly the same as in FIG. 1a. The connections between the transmitter 5, the receiver 6, and the transmitter/receiver string 11 are different.
In other words, the male terminal 12 of the handset string 11 is connected to the connecting string A.
The transmitter 5 is connected to the handset 6 via 9.

Next, FIG. 2B shows a connection when the circuit board 4 is mounted in a handset using the parts used in FIG. 2A. The connections within the handset are exactly the same as in FIG. 1b. Linga 7,
The connection to machine string 8 is different. That is, the ringer 7 is connected via the connecting string A9, and the machine string 8 is directly connected through the male terminal 12.

Therefore, as can be seen from FIGS. 2a and 2b, if two types of telephones, one in which the circuit board 4 is in the handset and the other in the base set, use the handset cord 11 of the present invention, This can be achieved using the same parts.

Figures 3a and 3b are block diagrams of another telephone according to the present invention. That is, by using a transmitter 5', a receiver 6', and a ringer 7' with lead wires 13 having female terminals 2 ₅ , 2 ₆ , 2 ₇ , the connecting string A9 can be removed and the number of parts can be reduced. It can be reduced. It is clear from FIGS. 1a and 1b that when a conventional handset cord is used, the number of parts cannot be reduced even with this method.

The present invention has been described above for the case where the transmitter and receiver are in the handset and the ringer is in the base set, but when the circuit board is mounted on the handset using the handset string of the present invention, the ringer is mounted on the handset. Therefore, it is also possible to implement only the machine string in the base set.

In addition, when mounting a speaker to perform reception amplification, etc., the ringer should be mounted on the same body as the circuit board and the speaker on the base set, or conversely, the speaker should be mounted on the same body as the circuit board. By using the handset/receiver cord of the present invention, it is possible to mount the ringer on the body as a base set without increasing the number of types of parts as described above.

Since the handset/receiver string of the present invention has the above-described configuration, regardless of whether the circuit board is mounted on the handset or the base set, it is possible to realize two types of telephones without increasing the types or number of parts. Therefore, it is possible to reduce costs in manufacturing and managing parts and assembling telephones.
