Description

[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention relates to a switch, in which a movable piece that opens a contact point is reversely swung by operation of an operator, and the movable piece is moved. This relates to the holding of a fixed contact piece in a switch that causes the contact point to be released from the fixed contact piece of the fixed contact piece.

(Traditional Kijutsu) Conventionally, this kind of switch was made in, for example, Japanese Patent Application Laid-open No. 61-1734.
As described in Publication No. 28, etc., an operator movably supported on the container body and a movable part supported in the container body so as to be swingable in the left and right direction are linked via a coiled spring. The movable piece is reversely swung, and the movable piece is sandwiched between the movable piece and the fixed contact piece disposed in the swinging direction of the movable piece is alternately brought into contact with and separated from the fixed contact piece so that the contacts are spaced apart. 412 is adopted in which a cover-like operating body having an outer diameter larger than the outer diameter of the body is removably attached to the above-mentioned operator from the surface of the body after being attached to the embedded box via a frame. was. In this structure, after installing the switch body to the recessed box that is embedded and fixed to the wall surface, etc., the switch body is installed through the frame.
A cover-like operating body is fitted to the covered panel and attached to the operating element from the surface side of the vessel. In a switch constructed such that an operating body with a large outer diameter is attached to the operator, one of the pair of fixed contact pieces must be mechanically extended into the space within the body. A structural switch, for example, a display element that displays the load status on the switch, a current transformer that supplies secondary current to a display element such as a light emitting diode, and other functional components are housed in a body of an existing size, and a pair of fixed If one of the contact pieces is placed at the bottom of the device body and the other is placed in the hollow part, and the movable piece swings between these fixed contact pieces, an operating body with a large outer diameter can be attached to the control element. In this case, when the operator is mounted, a large force acts on the operator, and the operator receives the force and presses the movable piece. At this time, if the movable piece is in contact with the fixed contact piece extending into the space of the vessel body, force moves in the direction of this movable piece pressing the fixed contact piece using the base end as a fulcrum, and the force moves into the space. There is a risk that the extending fixed contact piece may be deformed, causing a change in the contact gap, resulting in a problem that stable switching characteristics cannot be obtained.

Therefore, when the fixed contact piece is provided protruding into the container body or the operating body is attached to the operator using a bracket, the movable piece comes into contact with the fixed contact piece extending into the hollow part of the container body. Also, it is necessary to hold the stationary contact piece extending into the space so that it is not deformed by the pressing force of the movable piece.

(Problem to be Solved by the Invention) However, in the above-mentioned switch, if a rib or the like is formed inside the body to hold the fixed contact piece extending into the space, each component incorporated into the body will be damaged. In a structure in which the container is inserted through an opening at one end of the container, there are disadvantages such as the ribs protruding into the container making it difficult to assemble the parts, making assembly troublesome.

The present invention has been made in view of the above-mentioned problems, and uses an insulating case of a functional component such as a transformer built into the container body to prevent the fixed contact piece extending into the space inside the container body from being deformed or moved. The object of the present invention is to provide a switch that prevents the above problems, has a simple structure, and is easy to assemble.

(Structure of the Invention) (Means for Solving the Problems) The switch of the present invention includes a container body, a first fixed contact piece disposed along the inner surface of the container body, and a first fixed contact piece disposed along the inner surface of the container body. a second fixed contact piece disposed in a space inside the container body facing the second fixed contact piece, and a movable piece whose distal end is positioned between the first and second fixed contact pieces and provided inside the container body. The receiver has a movable piece whose base end is supported by the terminal piece so as to be able to be reversed and rocked, and which alternately approaches and separates from the first and second fixed contact pieces, and a movable piece that is engaged with the movable piece to reverse the movement. an operator having an operating part that swings;
a functional component disposed adjacent to the at least second fixed contact piece in the container body and housed in an insulating case; and an operating body detachably engaged with the operator from the outer surface side of the container body. The switch is characterized in that a restraining portion is formed protrudingly on the outer surface of the insulating case of the functional component, and is abutted against a surface of the second fixed contact piece that is opposite to the side that the movable piece contacts. This holding part is designed to hold the treasure piece placed in the space of the vessel.

(Function) When the switch of the present invention is assembled, the terminal piece and the movable piece are assembled into the body, and then functional parts such as a current transformer for supplying secondary power to a display element, such as a light emitting diode, etc. are housed in an insulated switch. When the case is assembled into the container body, the holding part of the case comes into contact with the surface opposite to the side where the movable piece of the fixed contact piece disposed in the space of the container body contacts, thereby holding the fixed contact piece. . Next, the operator is assembled into the vessel.

The thus-assembled device body is attached to an embedded box embedded and fixed in a wall surface or the like via a frame, and the plate is attached to the frame, and then the operating body is attached to the operator. When the operating body is attached to this operator, even if the movable piece contacts the first fixed contact piece, the first fixed contact piece is arranged along the inner surface of the device body, and the attachment of the operating body is movable by force. Even if the pressing force of the piece is applied, it will not be deformed, and even if the piece is in contact with the second fixed piece, the second fixed piece will be held in the holding part of the insulating case of the functional member. Therefore, the second fixed piece 1 and the second fixed piece will not be deformed or floated due to the pressing force of the movable piece.

Then, by the swinging operation of the steering body, the movable piece that has engaged with the rib part is reversely swung to open and close the contacts.
