The opening 4 is opened in a substantially rectangular shape along the longitudinal direction on the surface 2 a of the case body 2 as viewed from above. The liquid container 3 is filled with liquid metal 5 in a liquefied state at normal temperature and normal pressure (25 ° C. and 1 atm) through the opening 4. As the liquid metal 5, for example, a fusion gold made of gallium (Ga), indium (In) and tin (Sn) can be used.

液体収容部３の下部３ｂには、固定電極６が設けられている。固定電極６は、銅（Ｃｕ），金（Ａｕ），アルミニウム（Ａｌ）等の導電性を有する金属材料により形成された丸棒部材によって構成されている。固定電極６の一端部６ａ（図２参照）は液体金属５に接触させて液体収容部３側に固定され、固定電極６の他端部６ｂはケース体２の外部に延出され、図示しない各種電気部品に接続される。   A fixed electrode 6 is provided on the lower part 3 b of the liquid storage unit 3. The fixed electrode 6 is composed of a round bar member made of a conductive metal material such as copper (Cu), gold (Au), aluminum (Al) or the like. One end 6a (see FIG. 2) of the fixed electrode 6 is brought into contact with the liquid metal 5 and fixed to the liquid container 3 side, and the other end 6b of the fixed electrode 6 extends to the outside of the case body 2 and is not shown.

A substantially central portion of the movable electrode 7 is connected to an actuator (not shown) via an insulating member 8 formed of an insulating material such as plastic. Various actuators using electromagnetic force, hydraulic pressure, etc. can be adopted as the actuator for generating the driving force.

次に、図２を参照して、上記接点開閉装置１の動作を説明する。   Next, the operation of the contact switching device 1 will be described with reference to FIG.

本実施例にかかる接点開閉装置１では、オフのときは、図２（ａ）に示すように、可動電極７と液体金属５とは離間した位置にあり固定電極６，６間は電気的に切断されている。そして、オフからオンに切り換える際には、図２（ｂ）に示すように、アクチュエータによって可動電極７を下方に向けて移動させ、可動電極７の両端部７１，７１が各液体収容部３，３の液体金属５，５に接触することで、固定電極６，６間は液体金属５，５および可動電極７を介して電気的に接続し、通電される。また、オンからオフに切り換える際には、上記とは逆の動作が行われる。   In the contact switching apparatus 1 according to the present embodiment, when it is off, as shown in FIG. 2A, the movable electrode 7 and the liquid metal 5 are in a separated position and the fixed electrodes 6 and 6 are electrically connected. Disconnected. When switching from OFF to ON, as shown in FIG. 2B, the movable electrode 7 is moved downward by the actuator, and both end portions 71 and 71 of the movable electrode 7 are moved to the respective liquid storage portions 3 and 3. 3, the fixed electrodes 6 and 6 are electrically connected to each other via the liquid metals 5 and 5 and the movable electrode 7 to be energized. Further, when switching from on to off, the reverse operation is performed.

本実施例では、図３に示すように、可動電極７は絶縁部材８に回動可能に支持されている。具体的には、絶縁部材８の両端部８ａ，８ａの略中央に長手方向に沿って可動電極７の径よりも大径な貫通孔８１が形成されており、この貫通孔８１に可動電極７が挿入されている。   In the present embodiment, as shown in FIG. 3, the movable electrode 7 is rotatably supported by the insulating member 8. Specifically, a through hole 81 having a diameter larger than the diameter of the movable electrode 7 is formed along the longitudinal direction at the approximate center of both end portions 8 a and 8 a of the insulating member 8, and the movable electrode 7 is formed in the through hole 81. Has been inserted.

また、本実施例では、絶縁部材８の両端部８ａ，８ａに貫通孔８１から突出する可動電極７を短手方向（図３では左右方向）から挟み込むように一対の規制片８２，８２が設けられている。規制片８２は、長手方向に沿って可動電極７よりも長く延設されている。本実施例では、規制片８２が可動電極７の回動範囲Ｒを規制する回動規制部として機能する。   In the present embodiment, a pair of restricting pieces 82 and 82 are provided at both ends 8a and 8a of the insulating member 8 so as to sandwich the movable electrode 7 protruding from the through hole 81 from the short direction (left and right direction in FIG. 3). It has been. The restricting piece 82 extends longer than the movable electrode 7 along the longitudinal direction. In this embodiment, the restricting piece 82 functions as a rotation restricting portion that restricts the rotation range R of the movable electrode 7.

以上の構成によれば、本実施例にかかる接点開閉装置１では、図３（ａ）に示すように、可動電極７は、規制片８２との接触箇所８２ａ，８２ａ間で振り子状に回動することができる。このときの回動範囲Ｒは、開口部４の開口幅Ｄの範囲内で設定される。   According to the above configuration, in the contact switching apparatus 1 according to the present embodiment, as shown in FIG. 3A, the movable electrode 7 rotates in a pendulum shape between the contact points 82 a and 82 a with the regulating piece 82. can do. The rotation range R at this time is set within the range of the opening width D of the opening 4.

以上説明したように、本実施例にかかる接点開閉装置１では、絶縁部材８（支持部材）に可動電極７が回動可能に支持されているため、絶縁部材８に対する取付自由度が増大することで、絶縁部材８に可動電極７を固定する場合と比べて開口部４に対する可動電極７の取付位置を容易に決定できるので、接点開閉装置１の組立性をより向上することができる。また、可動電極７と液体金属とを接触させる際に可動電極７が横ずれした場合、開口部４に接触して可動電極７が回動するので、噛み込み等の動作不良を抑制することができる。   As described above, in the contact switching device 1 according to the present embodiment, the movable electrode 7 is rotatably supported by the insulating member 8 (support member), so that the degree of freedom of attachment to the insulating member 8 is increased. Therefore, since the mounting position of the movable electrode 7 with respect to the opening 4 can be easily determined as compared with the case where the movable electrode 7 is fixed to the insulating member 8, the assembly of the contact switching device 1 can be further improved. Further, when the movable electrode 7 is laterally displaced when the movable electrode 7 and the liquid metal are brought into contact with each other, the movable electrode 7 rotates by contacting the opening 4, so that malfunction such as biting can be suppressed. .

また、本実施例にかかる接点開閉装置１では、可動電極７の回動範囲Ｒを規制する規制片８２（回動規制部）を設けたため、規制片８２により設定した可動電極７の回動範囲Ｒ内に可動電極７を取り付ればよいので、接点開閉装置１の組立性をより向上することができる。また、開口部４の開口幅Ｄ内において回動範囲Ｒを設定することで、開口部４に可動電極７をより確実に挿入できるので、噛み込み等の動作不良を抑制することができる。   Further, in the contact switching device 1 according to the present embodiment, since the restriction piece 82 (turning restriction portion) for restricting the rotation range R of the movable electrode 7 is provided, the rotation range of the movable electrode 7 set by the restriction piece 82 is provided. Since the movable electrode 7 has only to be mounted in R, the assembly of the contact switching device 1 can be further improved. Moreover, since the movable electrode 7 can be more reliably inserted into the opening 4 by setting the rotation range R within the opening width D of the opening 4, it is possible to suppress malfunctions such as biting.

また、本実施例に係る接点開閉装置１では、可動電極７によって一対の固定電極６，６間の電気接続をオン／オフするようにしたため、アクチュエータ等の可動機構に連結される可動電極７と各種電機部品に接続される固定電極６，６とを分離して設けることができるので、接点開閉装置１の設計自由度を増大できる。   Further, in the contact switching device 1 according to the present embodiment, since the electric connection between the pair of fixed electrodes 6 and 6 is turned on / off by the movable electrode 7, the movable electrode 7 coupled to a movable mechanism such as an actuator is provided. Since the fixed electrodes 6 and 6 connected to various electric parts can be provided separately, the degree of design freedom of the contact switching device 1 can be increased.

以上、本発明の好適な実施例について説明したが、本発明は上記実施例には限定されず、種々の変形が可能である。例えば、ケース体，液体収容部，開口部，絶縁部材，規制片，固定電極，可動電極の形状等は種々のものを採用できる。また、上記実施例では、単一のケース体に複数の液体収容部を設けているが、複数のケース体にそれぞれ液体収容部を設けるようにしてもよい。また、上記実施例では、アクチュエータを可動電極に連結し、可動電極を移動させるようにしているが、アクチュエータをケース体に連結し、ケース体を移動させるようにしてもよい。また、上記実施例では、回動規制部としての規制片を絶縁部材（支持部材）に設けているが、ケース体あるいは可動電極に設けるようにしてもよい。このように、上記実施例に基づいて当業者によりなされる他の実施例、実施の形態および運用技術等は全て本発明の範疇に含まれる。   The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made. For example, various shapes such as a case body, a liquid container, an opening, an insulating member, a regulating piece, a fixed electrode, and a movable electrode can be adopted. Moreover, in the said Example, although the several liquid accommodating part was provided in the single case body, you may make it provide a liquid accommodating part in a some case body, respectively.
