Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 6-pole jack used for connecting various electronic devices.

[0002]

2. Description of the Related Art Conventionally, 3-pole or 4-pole jacks have been widely used in various electronic devices. For example, in FIG.
~ Fig. 47 is a front view and a bottom view of a 3-pole φ3.5 jack.
A side view, a printed circuit board hole reference diagram, and a circuit diagram are shown respectively, and FIG. 48 is a side view of a three-pole plug connected to this jack.

43 to 45, a jack 50 is shown.
Has a hole 52 penetrating from a housing 51 provided at the front part to a rear part for inserting a plug, and inside the hole 52, one end of each of a sleeve spring 53, a ring spring 54 and a tip spring 55 is formed. It is sticking out. The other end of each of the springs 53, 54, 55 is pulled out to the outside of the housing and protrudes from a through hole provided in the printed circuit board as shown in FIG. 46, and is used as a connection terminal to one device. To be done.

On the other hand, as shown in FIG. 48, the plug 60 has a tip 61, a ring 62, and a sleeve 63 integrally formed in a rod shape with insulating collars 64 and 65 interposed therebetween. The tip 61, the ring 62, and the sleeve 63 are respectively connected to one ends of the connecting wires of the cord 66.
The other end of 6 is connected to the other device.

To obtain the electrical connection by inserting the plug 60 into the jack 50 having such a structure, when the plug 60 is completely inserted into the jack 50, the sleeve spring 53 and the sleeve 63, the ring spring 54 and the ring. 62, the chip spring 55 and the chip 61 are connected to each other, and as a result, the devices connected to the jack 50 and the plug 60 are electrically connected.

In the process of inserting the plug, the ring spring 54 and the tip spring 55, and the ring spring 54 and the sleeve spring 53 can be electrically connected to each other.

While the above-mentioned 3-pole jack plug is widely used, recently, tape recorders, radio receivers, etc. have become multifunctional, and multi-pole jacks capable of communicating various control signals as well as voice signals. I need a plug.

Therefore, for example, two sets of the three-pole jacks and plugs are arranged in parallel to form six poles, and JP-A-4-
A 6-pole jack plug has been developed as disclosed in 118879 "Connecting Device". 6 of this connection device
The pole jack plug has a signal contact 68a, 68b, 68c and a control contact 69 on the plug as shown in FIG.
A structure provided with a, 69b, and 69c is disclosed.

[0009]

However, since the terminal arrangement of each pole is determined by the standard in the above-mentioned conventional three-pole or four-pole jack plug, it is not possible to modify it into a six-pole jack plug. It was impossible.

Also, the 6-pole jack plug, which uses two sets of 3-pole jack plugs arranged in parallel, becomes large in size,
The connection operation is not easy and the cost is high.

Further, the 6-pole jack plug according to the present invention has a problem that the contact property with the plug is not good because the mouthpiece of the drawn product is used for the sleeve part of the jack. Although a protrusion is put out on the inner ring to make contact with the sleeve part of the jack, the contact state becomes unstable due to a slight deformation because a sufficient spring follow (deflection amount) cannot be taken like a leaf spring. was there.

Therefore, the 6-pole jack according to the present invention has a problem in the 6-pole jack which solves the above-mentioned problems in the prior art.

[0013]

In order to solve the above problems, a 6-pole jack according to the present invention comprises a housing having a plug insertion hole, a tip spring incorporated in the housing, a ring spring, and a first sleeve spring. , A second sleeve spring, a first contact spring, and a second contact spring, and the tip spring, the ring spring, the first sleeve spring, and the second sleeve spring have respective contacts at the plug. The contact portion is arranged so as to project into the insertion hole, and each of the first contact spring and the second contact spring is a leaf spring.

A housing having a plug insertion hole, a tip spring incorporated in the housing, a ring spring, a first sleeve spring, a second sleeve spring, a first contact spring, and a second contact spring. And a tip spring, a ring spring, a first sleeve spring,
In the second sleeve spring, each contact is arranged such that the contact portion projects into the plug insertion hole, and the contact portion of the second contact spring is located in front of the contact portion of the first contact spring. Characterize.

Further, the first contact spring and the second contact spring are attached to the outside of the housing.

Further, the contact portion of the first contact spring and the contact portion of the second contact spring are outwardly directed.

The tip, the first middle ring, and the second
A four-pole plug integrally formed by sandwiching an insulating collar between the inner ring and the sleeve; and a first contact ring and a second contact ring on the cylindrical insulator fitted in the four-pole plug in a brim shape. When a 6-pole single-headed plug consisting of a 2-pole holder formed by disposing a contact ring is inserted into the plug insertion hole, the tip and the tip spring, the first middle ring and the ring spring, and the second A middle ring and the second sleeve spring, the sleeve and the first sleeve spring,
The first contact ring, the first contact spring, the second
The contact ring and the second contact spring are configured to come into contact with each other.

Further, the tip spring, the ring spring, and the first sleeve spring are incorporated from the rear part of the housing, and the first and second contact springs are incorporated from the front part of the housing. .

The 6-pole jack plug constructed as described above operates as follows. When the 6-pole single-head plug is inserted from the chip into the 6-pole jack plug insertion hole, the front part of the 6-pole jack is also inserted into the holder of the 6-pole single-head plug. The 6-pole jack and the 6-pole single-head plug come into contact with each other. Each pole is used, for example, in the following applications.
