Description

M285022 VIII. New Description: [New Technology Field] This creation system is about a circuit control protector structure. With a button pivoting at the pivot, the left and right ends of the button are respectively pushed against the contact piece. The end of the contact piece jumps up and down to form an energized (ON) or power-off (OFF) state of the circuit loop; and when the button is in the ON position of the circuit, the button does not limit the contact piece to make contact The film can freely jump off. When the current is overloaded, the contact piece is thermally deformed and bounces in the opposite direction to form a circuit breaker (OFF). [Prior Art] According to the various switch structures, there are many kinds of switch structures. The switch structure of the power supply mainly operates in two kinds of actuation strokes: ON (ON) and OFF (OFF), so the buttons and interlocking elements are in elastic contact. The interlocking relationship between the pieces plays a decisive key in the use quality and service life of the switch structure; in order to further prevent the electric power danger caused by the overheating of the circuit due to circuit current overload and the fire of the wire, there are various types on the market. All kinds of switches with current overload tripping structure. In general, the disadvantages of conventional switches are as follows: (a) The internal components of the switch are complicated in structure, the assembly is time-consuming, the actuation stroke is not simple, and the manufacturing cost is increased. (b) If the interlocking elements are misaligned with each other, the bending of the elastic contact piece cannot be surely positioned on one side, and the operation of the switch to perform energization (ON) or power off (OFF) is not correct. (c) When the current overload trips, the elastic contact piece cannot be jumped off and is positioned in the OFF position. When the elastic contact piece cools, it may jump back to the ON state, which cannot effectively guarantee the current overload state. Electrical Safety. M285022 (d) After the current overload trips, it cannot be directly linked, so that the button or button is turned back to the OFF position, which is not convenient for user identification and operation. [New content] Technical problem to be solved: This creation is to solve the shortcomings of the aforementioned conventional switch, to achieve the interlocking component of the simplified switch, and to achieve the power-off (OFF) and power-on (ON) action with a simpler and more effective linkage structure. When the current overload trips, it can ensure the power-off (OFF) state of the circuit and return the button or button to the OFF position. Technical means for solving the problem: The present invention is a circuit control protector (fourteen) which is pivotally connected to the opening of the box body by a button, and one end of the button extends downward to the end of the top contact piece, and the button is another One end is pivotally connected to a linking member, and the linking member is pivotally pivoted relative to the button, and the end of the linking member abuts against the other end of the contact piece; and the end of the extending end of the button pushes the contact piece by pressing the button to swing One end, or the other end of the thick end pushes the other end of the contact piece, so that the two ends of the contact piece jump up and down to form a circuit (ON) or power off (OFF) state; when the button is located When the circuit is turned on (ON), the linkage of the button does not limit the contact piece, so that the contact piece can freely jump. When the current is overloaded, the contact piece is thermally deformed and bounces in reverse to form a circuit circuit (OFF). The new technical means: This is a circuit control protector (fourteen), its main purpose is to swing the sister swing, press one end of the pull one end of the contact piece, or press the sister M285022 32 Elastic member 321 first buckle L 322 second buttonhole 13
