Problems solved by technology

However, if the voltage of the electric power supplied to the electrical or electronic device is high, the electric power may cause some effects on a human body, or some effects on an operation of electronic components.
Further, if the electric power supplied from the power source exceeds 100 V or is direct current with a high voltage, when a switch device is incorporated in a connector, a current commercially available switch cannot be used as it is.
For example, when the electric power supplied from the power source is direct current with 400 V, it may not be safe to use a switch device, which is currently used for electric power of an alternating current with 100 V as safety and reliability are not ensured.

first embodiment

Structure of Connector

[0041]The structure of a connector of a first embodiment is explained.

[0042]The connector of the embodiment is a jack connector 10 shown in FIG. 6 to FIG. 8 which is to be connected to a plug connector 300 (which is an example of another connector) shown in FIG. 1 to FIG. 5. Hereinafter, a connected structure of the plug connector 300 and the jack connector 10 is referred to as a connector as well.

[0043]First, the structure of the plug connector 300 is explained with reference to FIG. 1 to FIG. 5.

[0044]FIG. 1 is a perspective view of the plug connector 300, FIG. 2 is a top view of the plug connector 300, FIG. 3 is a side view of the plug connector 300, FIG. 4 is a bottom view of the plug connector 300, and FIG. 5 is an elevation view of the plug connector 300.

[0045]The plug connector 300 includes a cover 310, three plug terminals 321, 322 and 323, and a cable 330. Further, the cover 310 of the plug connector 300 is provided with a protection portion 311 and an ...

second embodiment

[0135]For the switch device or the like, when a failure such as a breakage or a short occurs between the movable contacting portion and the fixed contacting portion, the short of the contacting portions is more fatal compared with the breakage. For the case of breakage, even when breakage occurs, the result is just that the electric power from the power source or the like is not supplied. Thus, there is no problem in an aspect of safety. However, for the case of a short, if the short occurs, supplying of the electric power from the power source or the like continues and cannot be stopped. Thus, the failure expands and the problem in the aspect of safety occurs. Thus, it is better to cause the breakage rather than causing the short, if any failure occurs. In the second embodiment, the switch device 100 is configured to cause the breakage rather than the short.

[0136]FIG. 19 is a schematic plan view of an example of the switch device 100 and FIG. 20 is an elevation view of an example o...

Abstract

A switch device includes first and second contacting portions including first and second fixed contacting portions and first and second movable contacting portions configured to contact the first and second fixed contacting portions, respectively and provided to be adjacent from each other; and a magnet unit provided such that a first pole is positioned to face the first contacting portion and a second pole is positioned to face the second contacting portion to generate magnetic fields between the first fixed contacting portion and the first movable contacting portion and between the second fixed contacting portion and the second movable contacting portion, respectively.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a switch device and a connector.[0003]2. Description of the Related Art[0004]Generally, an electrical or electronic device is driven by supplying electric power from a power source of the like. When supplying the electric power from the power source or the like, the electric power is supplied to the electrical or electronic device through connectors. The connectors for connecting the electrical or electronic device and the power source may be a combination of a jack type connector and a plug type connector configured to be fitted in the jack type connector, as described in Patent Documents 1, Patent Documents 2 and the like.[0005]Recently, as a countermeasure for global warming or the like, supplying of electric power of a direct current with a high voltage has been considered even for the power transmission in a local area. By using the electric power of a direct current with a high vol...
