Abstract

PURPOSE:To make a connector favorable in any aspect such as miniaturization, assembling property, cost, strength and appearance by integrating six poles in total with a jack and a plug respectively, including an independent connecting section for three poles for control signals in addition to a connecting section for three poles for audio signals. CONSTITUTION:A connecting jack 3 is integrally formed with both a ferrule 2 as a first connecting section for control signals in addition to contacts 11a through 11c for audio signals and a spring side terminal 6 as a third connecting section. On the other hand, a connecting plug 4 is integrally formed with connecting terminals 4a through 4C for audio signals faced to the first contact 11d for connecting jack 3, a contact 4d faced to the first contact 11d for control signals of the connecting jack, the ferrule 2 as a second contact, and a ring shaped spring connecting terminal A1 around the circumference of a plug 4. The connecting terminal A1 is provided with a slit 1b in the long diameter direction, and is also provided with paired contacting projected sections 1a in the short diameter direction. And when the connecting terminal is engaged with the ferrule 2 of the connecting jack 3, a stable contact can thereby be provided. A connecting terminal B5 faced to the side terminal 6 as a third contact is formed in such a way that the outer circumference is covered while a spacer 7 is being held in between.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connection device comprising a connection plug and a connection jack for headphones used in tape recorders, radio receivers, and the like.

2. Description of the Related Art In recent years, the internal structure of audio equipment such as tape recorders and radio receivers has become more dense, and there is a trend towards smaller sizes and multi-functionality.

2. Description of the Related Art Conventionally, earphones or headphones used in audio equipment are known to have an operating device on a relay part of the cord for remote control, which allows operating other functions of the equipment in addition to sound. In this type of device, as shown in Fig. 5, a separate line member for remote control is used to provide a plug 21 separate from the plug 20 for the tone-determined signal, and the main device also supports these plugs. The audio jack and remote control jack were arranged separately. Furthermore, as shown in FIG. 6, a device in which paired multi-pole connectors 22 are arranged is also known.

Problems to be Solved by the Invention However, in the configuration shown in Figure 4, in order to detect signals other than audio from remote control, etc., a connection device such as a separate jack for remote control is required in addition to the audio jack. Because of the tight internal space of small audio equipment, which tends to become multi-functional, it is extremely difficult to install separate parts. was also not satisfactory. Further, the structure shown in FIG. 5 has problems in that it is weak in strength, cannot be used with conventional headphones, and is unsatisfactory in appearance.

The present invention solves these conventional problems, and has a simple configuration that allows a single jack or plug to be used for remote control operations other than audio signals, thereby reducing the size of the device. The purpose is to provide an excellent connection device that can also contribute to the development of technology.

Means for Solving the Problems In order to solve the above problems, the connection device of the present invention is provided with three connection plug contacts for audio signals, and an audio signal connected to the plug and integrally connected to the above three poles. Covers the outer periphery of the first contact of a signal system different from the signal, the ring-shaped contact of a signal system different from the audio signal, and the ring-shaped second contact provided integrally with the plug. A connection plug is provided with a cylindrical third contact configured as shown in FIG. , the third contact is similarly connected with a connecting terminal having spring properties, and the second contact is integrally provided with a connecting terminal for a signal system different from the audio signal configured to be connected in the shape of a base. It consists of a connection jack.

Operation The present invention has the above-mentioned configuration, which enables 6-pole connection with a single jack and plug, resulting in miniaturization.

It is extremely advantageous in terms of ease of assembly, cost, strength, and appearance.

Embodiment Hereinafter, a connection device according to an embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2.

FIG. 3 is a perspective view and a sectional view showing essential parts of the connecting device of the present invention, and FIG. 4 is an external perspective view of a device equipped with the same device.

In the figure, reference numeral 10 denotes a main body of the device, and the connection jack 3 is soldered to a printed wiring board 9, and is arranged and fixed so that the base 2 protrudes from the main body 10 of the device. Connection jack 3
contacts 11a, llb, which have spring properties for audio signals;
Separately from the llc and its contacts, a base 2 as a first connection part for control signals, and a side terminal 6 having spring properties as a third connection part are integrally formed. - On the other hand, the connection plug 6 has the contact 11 of the connection jack 3.
Apart from the audio signal connection terminal 4a r4b-4c facing the 1lb-11c and those connection terminals, the contact 4d and the second contact 4d facing the control signal first contact lid of the connection jack A ring-shaped springy connection terminal A1 facing the cap 2 as a contact point is integrally formed around the base of the plug 4, and the connection terminal A1 has a cylindrical shape with an elliptical cross section as shown in FIG. A slit 1b is provided in the major axis direction, and a pair of opposing contact protrusions 1a are provided in the minor axis direction.
is provided, and when the connection jack 30 is engaged with the base 2, it is configured to flex as shown by the two-dot chain line and to obtain stable contact. A cylindrical connection terminal B5 facing the side terminal 6 as a third contact is configured to cover its outer periphery with a spacer 7 sandwiched therebetween for insulating the connection terminal A1.

By configuring as described above, it is possible to connect six poles with a single jack and plug, and it is also compatible with conventional stereo plugs. Furthermore, since the plug is configured to be rotatable relative to the jack, it is advantageous in terms of stability of contact.

Effects of the Invention As described above, the connection device of the present invention integrates a total of six poles into the jack and plug, including an independent three-pole connection part for control signals, in addition to the three-pole connection part for audio signals. This structure is effective in reducing the number of parts and reducing costs. It is also compatible with the stereo plugs used in conventional headphones. In particular, according to the present invention, since the plug is configured to be rotatable relative to the jack, it is advantageous in terms of stability of contact, and the connecting plug for the device body and headphones can be miniaturized. It is advantageous.
