Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supra connector used between a supra used by a telephone operator in a mail order business and a broadcasting business and a telephone line cord.

[0002]

2. Description of the Related Art In a mail-order business, for example, a life consultation on toll-free telephone calls, and a broadcasting business for programs in which listeners participate, etc.
An operator accepting a telephone responds to the telephone by wearing a supra equipped with headphones and a microphone for conversation on the head. This supra has a binaural type and a monaural type, but in the broadcasting business of TV stations and radio stations,
Since there is almost no need to listen to anything other than telephone conversations, binaural supra is often used. On the other hand, in the mail-order business, a one-ear type supra is frequently used to listen to a telephone call with one ear and to listen to an instruction or a conversation other than the telephone call with one ear.

[0003] These operators search for materials such as catalogs and operate personal computers while receiving telephone conversations. For this reason, the frequency of moving away from the place where the phone is located, such as moving from the place where the phone is located to another place where the material is located, is extremely high. Since it is difficult to attach and detach the supra every time this movement occurs, a supra connector is interposed between the supra and the telephone line cord (modular cord). Is moving with the on the head.

[0004]

However, in this supra connector, the plug and the socket are joined by the joining force by the fitting of the plug terminal on the plug side and the socket terminal on the socket side. Therefore, when a plug is attached to this socket, the tip of the plug terminal is pressed and inserted into the hole of the socket terminal and fixed by the force of fitting, so that a certain amount of force is required. Further, when the plug is removed from the socket, it is necessary to pull out the plug and the socket by holding them both by hand, so that a force is required in the insertion direction.

[0005] Therefore, the operation of attaching and detaching the plug and the socket cannot be performed with one touch, which is a complicated and troublesome operation. Also,
On the other hand, the telephone and conversation modular cords connected to this Supra are 2 cores for home use, but 4 cores, 6 cores and more for conversational earphones and microphones for business use. As a result, the outer diameter of the coating becomes thicker, the weight increases accordingly, and since it is in a spiral shape so that it can expand and contract, it has a telephone jack and a supra worn by the operator. The weight of the cords between them is large, which hinders the work of the operator. In order to avoid this, this modular cord tends to be thinner and lighter, and it has been reduced from a conventional one having a width of about 4.5 mm and a thickness of about 2.4 mm to a thinner and less than less than half. is there.

[0006] However, the conventional supra connector has a problem that it is large in size and heavy in weight because it is for a conventional thick and heavy cord. And there is no Supra connector for this thin modular cord, it can be applied to this thin modular cord,
Lighter and more compact supra connectors are required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to attach and detach a plug and a socket for a supra by using the attraction force of a magnet or the attraction force of a suction pad. Accordingly, it is an object of the present invention to provide a supra connector which can be extremely easily attached and detached, has a simple structure, and is lightweight and compact.

[0008]

In order to achieve the above-mentioned object, a supplier connector comprising a plug having a plug terminal and a socket having a socket terminal is constituted as follows. First, a magnet is arranged on one of the plug and the socket, and a magnetic material member is arranged on the other, and by an attractive force generated by the magnetic force of the magnet,
The plug and the socket are configured to be detachably joined.

According to this configuration, the plug terminal and the socket terminal can be joined by a magnetic force without depending on the fitting force, so that the plug and the socket can be attached and detached very easily. Further, since there is no need to generate a fitting force, the plug terminal and the socket terminal can be reduced in size, and the connector can be reduced in size and weight. A magnetic material member that contacts a magnet disposed on one of the plug and the socket is provided, and a magnetic material member is disposed on the other, and an attractive force generated by a magnetic force of the magnetic material member that contacts the magnet. Thereby, the plug and the socket are detachably joined.

[0010] With this configuration, the magnet can be arranged at a place away from the joint surface, such as after the plug terminal or the socket terminal, so that an increase in the diameter of the plug or socket can be suppressed and the size can be reduced. Can be. Further, magnets are arranged on both the plug and the socket so as to generate an attraction force in a joint state of the connector, and the plug and the socket are detachably joined by the attraction force between the two magnets. The configuration is as follows.

With this configuration, the magnets attract each other only when the wiring of the plug and the socket are correctly joined, so that it is not necessary to manually adjust the positional relationship between the plug terminal and the socket terminal at the time of joining. It can be joined by simple wiring. Then, in the plug, the four plug terminals and the magnet or the magnetic material member are arranged side by side in one character, and in the socket, the socket terminals are respectively arranged at positions facing the four plug terminals. In addition, the magnetic material member or the magnet is arranged at a position facing the magnet or the magnetic material member.

[0012] With this configuration, the supra connector can be formed flat and thin, so that it is easy to hold and detach.
Further, since the arrangement of the plug terminals and the socket terminals is one character as compared with the cylindrical type, it is easy to make the positional relationship correct and to join them. In addition, since the plug terminals and the socket terminals are arranged in parallel on the plane, the work of connecting the cord to the core wire is simplified.

Further, in this arrangement of one horizontal character, the positional relationship between the plug terminal or the socket terminal and the magnet or the magnetic material is not particularly limited, but if the magnet or the magnetic material is disposed at both ends of the plug terminal or the socket terminal, Since the suction force is generated when the plug and the socket come into contact on one side, the operation is easy. This magnetic material member is magnetized by contacting a magnet,
It is a member that can attract another magnetic material, or a member that is attracted by magnetic force. Specifically, it is iron, cobalt, nickel or the like or an alloy thereof, and in addition, there is a manganese alloy, a ferromagnetic rare earth metal or the like.

A supra connector comprising a plug having a plug terminal and a socket having a socket terminal is provided with a suction pad on one of the joining surfaces of the plug and the socket and the suction pad on the other joining surface. Is provided so that the plug and the socket are detachably joined by the suction force of the suction pad.

With this configuration, the suction pad (suction cup) can be made small and lightweight, so that the supra connector can be made very lightweight and small.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the supra connector 11 of the first embodiment according to the present invention utilizes the attractive force of a magnet 23, and the plug 2 has a cylindrical shape made of synthetic resin.

Further, a plug terminal support member 25 fitted inside the iron cylindrical member 24 holds four plug terminals 22 in a cross shape, and a cord 4 is provided behind each of the plug terminals 22.
Are connected. On the other hand, the socket 3 detachably joined to the plug 2 is provided with an iron cylindrical member 34 which is a magnetic material member inside a cylindrical socket case 31 made of a synthetic resin, and further has a socket terminal support member inside thereof. 35 is fitted, holding the socket terminal 32 in a cross-shaped,
Each core wire of the cord 4 is connected to the rear of each socket terminal 32.

As the magnetic material member, an iron cylindrical member 2
4, 34 are used, but the material is not necessarily limited to iron, a member that can be magnetized in contact with a magnet and attract other magnetic materials, or a member that is attracted by magnetic force, Specifically, iron, cobalt, nickel, or an alloy thereof, a manganese alloy, a ferromagnetic rare earth metal, or the like may be used.

For the plug terminal 22 and the socket terminal 32, a spring-type connector pin which has a built-in spring and which can slide the tip of the plug terminal 22 and press against the end surface of the socket terminal 32 is used. Plug terminal of this connector pin
The socket terminal 32 and the socket terminal 32 cannot generate a joining force by fitting, but the tip of the plug terminal 22 can slide and contact, and the receiving surface of the socket terminal 32 on the receiving side can be flattened. However, the relative position accuracy may be coarse. Since the plug terminal 22 and the socket terminal 32 are small and lightweight, the plug 2 and the socket 3 can be reduced in size and weight.

As an example of the dimensions of the plug terminal 22 of this connector pin, the plug tip diameter is 2.0 mm, the plug tip length is 4.7 mm, the stroke is 3.5 mm, and the total length is 1.
The pressing force is 100 gf at 3.2 mm. The outer diameter of the four-core plug 2 employing the plug terminal 22 is about 14 mm. A part of the iron cylindrical member 24 on the plug 2 side and a part of the iron cylindrical member 34 on the socket 3 side are provided with guide projections 26 and 36 protruding in the axial direction, respectively. Guide recesses 37 and 27 that are recessed in the axial direction are provided in the portion 24. The guide convex portions 26 and 36 and the guide concave portion
37 and 27 are engaged with each other to perform positioning when the plug 2 and the socket 3 are joined.

The positioning guide projections 26, 36
Although the guide recesses 37 and 27 are provided on the iron cylindrical members 24 and 34 in the embodiment of FIGS. 1 to 3, they may be provided on the plug case 21 and the socket case 31. Further, other means, such as providing an engaging projection and an engaging hole having a cross-sectional shape such as an oval on the plug terminal supporting member 25 and the socket terminal supporting member 35, as the engaging projection is inserted into the engaging hole. Alternatively, the positioning may be performed.

When the iron cylindrical member 34 on the socket 3 side is attracted by magnetic force, the iron cylindrical member 24 comes into contact with the magnet 23.
The iron cylindrical member 24 is attracted by the magnetic force of the iron cylindrical member 24, but the iron cylindrical member 24 may be omitted, the magnet 23 may be provided on the joint surface, and the iron cylindrical member 34 may be directly attracted by the magnet 23. it can. In this case, it is necessary to secure a place where the magnet 23 is provided on the joint surface on the plug 2 side.

Supra connector 11 having the above configuration
According to this, the iron cylindrical member 24 in contact with the magnet 23 on the plug 2 side allows the magnetic flux generated by this magnet 23 to pass,
Since a magnetic force is generated, the iron cylindrical member 34 on the socket 3 side can be attracted by the magnetic force on the joint surface side of the iron cylindrical member 24. Since the suction force rapidly increases when the distance between the two 24 and 34 becomes short, the plug 2 and the socket 3 can be joined by the suction force. Also, the distance between the magnetized iron cylindrical member 24 on the plug 2 side and the iron cylindrical member 34 on the socket 3 side is increased by bending the plug 2 and the socket 3 against the joining force between the magnet 63 and the iron member 74. When separated, the attractive force due to the magnetic force rapidly decreases as the distance increases, so that the plug 2 and the socket 3 can be easily separated.

Further, since the attraction force of the magnet 23 is utilized, the attraction force due to this magnetic force is hardly deteriorated, so that a durable supra connector can be manufactured. Then, instead of being directly attracted by the magnet 23, an iron cylindrical member 24 that comes into contact with the magnet 23 is provided, and the plug 2 and the socket 3 are attracted by the attractive force generated by the magnetic force of the iron cylindrical member 24.
Is configured so that the magnet 23 can be disposed at the rear of the plug terminal 22 or the socket terminal 32, so that an increase in the diameter of the plug 2 or the socket 3 is suppressed and the size is reduced. be able to.

Instead of providing the magnetic material member 34 attracted by magnetic force on the socket 3 side, a magnet is provided,
Magnets are arranged in both the plug 2 and the socket 3, and the opposite polarities of the magnets are arranged so as to generate an attractive force at the time of joining.
May be configured to be detachably joined. According to this configuration, since the magnets attract each other only when the relative positional relationship between the plug 2 and the socket 3 is in the correct positional relationship, the guide convex portions 26 and 36 and the fitting concave portions 27 and 37 are not provided. Also, incorrect connection can be prevented and the contact between the plug terminal 22 and the socket terminal 32 can always be made correct.

That is, the guide convex portions 26 and 36 and the guide concave portion 27,
Since the 37 is not required, a simpler structure can be achieved.Furthermore, when connecting, there is no need to search for the positional relationship between the guide projections 26, 36 and the guide recesses 27, 37, so attachment / detachment is extremely difficult. It will be easy. Next, the supra connector 12 according to the second embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 7, the magnet 63 is made of an attractive flat shape, in which four plug terminals 62 are arranged side by side.
Thus, it is configured to directly attract the iron piece 74 which is a magnetic material member attracted by the magnetic force of the socket 7.

As shown in FIGS. 4 and 7, this plug 6 has magnets 63 disposed at both ends inside a flat cylindrical plug case 61 made of synthetic resin, and holds a plug terminal 62 inside. It is formed by fitting a plug terminal support member 65.
As shown in FIGS. 4 and 6, one of the sockets 7 has iron pieces 74 arranged at both ends inside a flat cylindrical socket case 71 made of synthetic resin, and holds the socket terminal 72 inside. It is formed by fitting a socket terminal support member 75.

In this plug 6, the positioning guide projection 66 is provided so as to protrude from the upper half of the joint surface side of the plug case 61, and the guide recess 67 is provided in the plug case 61.
61 is provided by cutting out the lower half of the joint surface side. Further, in the socket 7, the guide protrusions 76 for positioning are used.
Is provided so as to protrude from the lower half of the joint surface side of the socket case 71, and the guide recess 77 is provided by cutting out the upper half of the joint surface side of the socket case 71.

The guide projections 66 and 76 and the guide recess 7
By the engagement with 7, 67, positioning at the time of joining is performed, and each plug terminal 62 is configured to contact the corresponding socket terminal 72. Supra connector 12 with this configuration
According to this, the magnet 63 and the iron piece 74 are directly attracted by the magnetic force of the magnet 63, so that the plug 6 and the socket 7 can be removably joined together, and the magnet 63 and the iron piece 74 resist the attractive force of the magnet 63 and the iron piece 74. By bending the plug 6 and the socket 7 to separate the magnet 63 and the iron piece 74, the plug 6
And the socket 7 can be separated. Therefore, it can be separated by one-handed operation.

Further, since the supra connector can be formed to be flat and thin, it is easy to hold and detachably operate. In addition, since the plug terminals and the socket terminals are arranged in parallel on the plane, the work of connecting the cord to the core wire can be simplified. The supra connector 13 according to the third embodiment of the present invention shown in FIGS. 8 to 10 is the same as the first embodiment shown in FIGS.
Unlike the second embodiment, the suction pad 88 made of silicon rubber or the like is used.

In this supra connector 13, the plug 8 is a cylindrical member having a guide convex portion 86 and a guide concave portion 87 inside a cylindrical plug case 81 made of a synthetic resin as shown in FIGS. A plug terminal support member 85 holding the plug terminal 82 is fitted inside the connector 84. The core wire of the cord 4 is connected to the rear of the plug terminal 82.

On the other hand, the socket 9 joined to the plug 8
As shown in FIGS. 8 and 9, a cylindrical member 94 having a guide convex portion 96 and a guide concave portion 97 is fitted inside a cylindrical socket case 91 made of a synthetic resin. The socket terminal supporting member 95 holding the above is fitted. The core wire of the cord 4 is connected to the rear of the socket terminal 92.

A suction pad 88 is provided substantially at the center of the plug terminal support member 85 on the plug 8 side, and the surface of the joint surface 95a of the socket terminal support member 95 on the socket 9 contacting the suction pad 88 is a flat suction surface. Formed on the surface 95, the suction pad 88
Is configured to exert an attractive force when is pressed. The suction pad 88 has a small diameter of about 3 mm.

According to the supra connector 13 having this configuration, the guide projections 86 and 96 are respectively connected to the guide recesses 97 on the mating side.
When the plug 8 is pressed against the socket 9 by engaging with the socket 87, the suction pad 88 is adsorbed on the joint surface 95.
Even when the pressing force is removed, the connection between the plug 8 and the socket 9 can be maintained by the suction force of the suction pad 88. Further, when the plug 8 and the socket 9 are bent, the side of the suction surface 95 of the suction pad 88 is opened and air enters and the suction force is lost, so that the suction pad 88 can be easily separated.

Further, since the suction pad 88 can be made small and lightweight, the supra connector 13 can be made very lightweight and small. As described above, the supra connectors 11, 12, and 13 according to the present invention include the magnets 23 and 63.
Since the plugs 2, 6, 8 and the sockets 3, 7, 9 are joined by the suction force of the suction pad 88 or the suction force of the suction pad 88, the attachment / detachment between them can be extremely easily performed. for that reason,
The working efficiency of the operator using the supra can be significantly increased.
