[Invention or problem to be solved]

In this way, conventional connectors are connected to a mating connector by fitting or screwing together, and in the former case, there is a risk of it becoming unstable and coming off over time, while in the latter case, The join operation was cumbersome. Additionally, the housing, which is molded from synthetic resin, has poor electromagnetic shielding properties, and there is the problem that radiated noise may be generated from the connector, causing interference with the equipment.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a connector that allows stable and simple connection and does not generate radiated noise.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a connector that includes a pair of connecting members that make electrical or optical connections with each other, and a pair of housings that are attached with the connecting members and that are removably coupled to each other. 5- The pair of housings are formed of a magnetic material, and the magnetic material of at least one of the housings is magnetized.

Further, in the present invention, it is preferable that the outside of the housing is covered with a case that shields magnetic force, or that at least one of the housing or the case is formed with a guide for positioning relative to the other party. .

[Effect]

Since either the housing formed of a magnetic material or the other housing is magnetized, the housings actively attract each other to maintain a reliable and stable connection state. Further, since the housing formed of a magnetic material has electromagnetic wave shielding properties, it effectively reduces radiation noise.

In a configuration in which the housing is covered with a case, there is no leakage of magnetic force and there is no effect on peripheral devices such as magnetic recording devices. Furthermore, by providing a guide, the connections between the connectors are made in the correct position.

〔Example〕

Hereinafter, the present invention will be specifically explained with reference to illustrative examples. Note that in each embodiment, the same elements are designated by the same reference numerals, thereby omitting redundant explanation.

FIG. 1 shows a first embodiment of the present invention, in which connectors 3 and 4 are fixed to two corresponding circuit boards 1 and 2 so as to face each other. The connector 3 on the side of the circuit board 2 includes a contact 6 whose base end is connected to the circuit of the circuit board 1 by solder 5, and a plug 7 which is fixed to the lower surface of the circuit board 1 and through which the contact 6 is inserted. On the other hand, the connector 4 on the circuit board 2 side is connected to the base end or the circuit on the circuit board 2 by solder 5, and is fixed to the upper surface of the circuit board 2 with a contact 8 having a bifurcated tip. It consists of a socket 9 inserted through it. Contacts 6 and 8 are connecting members that connect electrically between circuit boards 1 and 2 by inserting one tip into the other, and plug 7 and socket 9 are used to connect these connecting members to each other. It is a housing that can be used.

Both the plug 7 and the socket 9 are molded by magneto, and magnetic poles are arranged on each opposing surface so that different poles are located. Therefore, when the plug 7 and the socket 9 are brought close to each other, a magnetic attraction force is exerted between them, so that the plug 7 and the socket 9 fit together in a mutually attracted state. Therefore, plug 7, socket 9
The mutual bonding force is strong, and the contacts 6 and 8 do not easily separate, allowing stable connection between the contacts 6 and 8 to be maintained.

In addition, when the plug 7 and the socket 9 are connected, the periphery of the contact 6.8 is covered with a magnetic material (magnet) to provide electromagnetic shielding, so radiated noise from the contact 6.8 may leak to the outside. This also reduces radio wave interference.

That is, the connector shown in FIG. 3 is covered with the outside of the plug 7 or the case 14, and the outside of the socket 9 is covered with the case 1.
Covered by 5. These cases 14 and 15 are made of an abrasive material such as a magnetic material that shields magnetic force, and when the plug 7 and socket 9 are connected, they cover the outside of these to prevent leakage of magnetic force. Therefore, it is possible to prevent an adverse effect on external equipment such as a magnetic storage device that causes data destruction due to magnetic force.

In particular, in the connector shown in FIG.
, 1.5 overlap each other in a lap state.
, 4a, and 15a are formed, which is effective in preventing leakage of magnetic force. Further, such stepped portions 14a, 1
Since 5a acts as a guide when the plug 7 and socket 9 are connected, the plug 7 and socket 9 can be positioned accurately and easily.

In the connector shown in FIG. 4, a case 16 is provided only on the outside of the socket 9. The case 16 is formed of a material that shields magnetic force, and has a height that covers the outside of the plug 7 when the plug 7 is connected to the socket 9. Therefore, since not only the socket 9 but also the outside of the plug 7 is covered by the case 16, leakage of magnetic force can be prevented. In addition, this case 16
A tapered surface 16a is formed at the tip of the plug 7 so as to perform a kite when the plug 7 approaches the socket 8. In this case, guides can also be formed in the plug 7 and the socket 8.
