Abstract

A trip linking structure of safety switch is introduced. The button pushing links the position rod active simultaneously. The position rod, ring type ladder way and position-linking sheet are mutually linked to form a cycling positioning relationship. Then the position-linking sheet directly pushes or pulls the touch sheet to switch ON or OFF. Under the ON state, the circuit loop is turned off by the reverse bending of the touch sheet induced by the heating distortion if the current is overloading. Its feature is: an opening trough is made on the position-linking sheet. There are Y-type trenches with central channel in the said opening trough so the positioning rod slides along the trenches. The rod directly links the linking sheet, touches sheet and hence switches ON or OFF. The first and the third trenches are the positioning trenches of the positioning rod when the circuit is OFF and ON respectively. Under the normal state, during the OFF to ON operation, the second trench is the path that the positioning rod operates. When the current of the circuit loop is overloading, during the OFF to ON operation, the touch sheet will be rapidly reverse-bended by the heating distortion and then push the position linking sheet. At this moment, the second trench provides the free rotation path of the position linking sheet not blocked by the positioning rod. Hence the touch sheet is successfully bended and escapes quickly and then the circuit loop is OFF.

Description

1262522 ------ V. Description of invention (1) [Technical field to which the invention belongs] The system is related to a safety switch tripping linkage structure, which is a dream positioning telecontrol H h ^ 4 actuation The position bar and the annular stairway and the ΐ technology form a yoke ring positioning relationship, and the positioning interlocking piece is straight! 'This: f' forms the switch energization (10) or power off (OFF); the central splicing, the slotting of the linkage piece The internal and external complex movements are connected to the plurality of grooves of the slotted slot. The sliding cup 3 is connected to the clamping piece to directly push and pull the contact piece to (10) or power off (0FF); It is made in the circuit loop: electricity: in the overload state 'from power-off (10)F) to power-on (10), the contact piece will be quickly deformed by heat deformation, and the relative displacement of the groove is not affected by the positioning rod. Obstruction pull (OFF, bend and quickly jump, form the circuit loop Γ ^ (OFF) state. ^ Electric [previous technology] Press, the general power switch its operation is mainly in the actuating stroke, It effectively performs the linkage of the internal components of the switch: two simplified switch components to reduce the production cost, switch junction The continuation of the structure has become an important common issue for manufacturers. The patents for improving the switch structure are numerous, such as U.S. Patent Nos. 4,167,720, 4,937,548, 5,223,8 1 3, 5,451, 72 9 No. 5, 558, 2 1 1 ~ and so on, but all of them are on page 5, 1262522. V. Inventions (2) The previous cases have common shortcomings, as follows: (1) The linkage of components is complex The itinerary is complicated, and the #immediate action relationship between the button and the terminal component is generated, which also increases the manufacturing cost. (2) The actuating relationship is not correct, and the chance of failure is increased, which is not conducive to the safety consideration of the consumer. (3) by button (button) Direct or indirect compression of the contact piece to form a power-on or power-off. The valley easily causes poor contact or crack damage, reduces the power quality, and shortens the service life. US Patent No. 5, 2 2 3, 8 1 3 The structure disclosed by the number, after pressing the button, first link the link below the button to connect the upper and lower swinging components via the connecting rod, and then press or loosen the contact piece below the contact piece to make the upper contact contact or jump off. Contact Or cut off the circuit; it is a way to press or release the contact piece indirectly by the button. 'In the ideal situation, there should be no problem in operation. However, the components are complicated to copy for higher cost, increase operation failure, and linkage. Line = slow response ^ and obvious disadvantages of potential fracture or elastic fatigue of the contact piece, and during the operation of breaking from $獍 (OFF) to energization (ON), if the current in the circuit loop is overloaded, the contact will overheat and generate Sparks, causing danger of electricity, ^, etc., become a common problem of manufacturing and users, so it is necessary to re-enter _ = good. V ^ [Summary of the Invention] Technical Problem to be Solved by the Invention: The present invention is to solve the conventional switch linkage structure Complex components, system

The safety switch tripping and interlocking structure described in claim 1 of the patent scope, 1262522 Sixth, the scope of application for patents, the position: dry, the fixed 彳 纟曰 纟曰 Γ I below the positioning rod: can be set relative to the button pendulum set ring ^ ^ the bulge bends the switch button The annular stairway provided by the movable body of the movable body ϋ The main body of the switch is provided with a diagonally convex piece-shaped stairway, and the annular stairway 7 is as claimed in the patent scope!适#,+,# &人 ΓΛ Λ Λ ^^# J Bu Between the body, and a to v An elastic member is a compression spring 0, 8 · As stated in the patent scope! The safety switch jumps off the interlocking structure, wherein the body is provided with at least one groove for accommodating the elastic member between the button and the switch body, and at least one buckle groove is disposed between the switch body and the button, A cross bar and at least one clasp. 9. The safety switch tripping and interlocking structure according to claim 1, wherein the positioning rod has a perforation at the upper end, a perforation of the positioning rod, and a binding member provided by the elastic member in the button, and the elastic member is used. The perforating periphery of the force pushing top positioning rod combines the positioning rod with the binding column of the button, and the positioning rod can be perforated into the axis and oscillate with respect to the button. The elastic member negatively biases the positioning rod to the direction of the annular step. The safety switch tripping interlocking structure according to claim 9, wherein the elastic member is a compression spring. II. The safety switch tripping interlocking structure according to claim 1, wherein the side of the annular stairway is provided with /a 1262522 VI. Patent application scope The lower side piece of the positioning linkage piece is provided with a coupling hole; a bolt is passed through the coupling hole of the positioning linkage piece, and is integrated into the combined hole of the annular side, so that the positioning linkage piece is The coupling hole is an axis, and the annular ladder of the switch body can be oscillated to the left and right; by oscillating the positioning piece, the inner side of the groove of the groove of the positioning link and the inclined piece of the annular step are formed. The shank end of the closed or open position rod is cyclically positioned below or from the opening to the annular step end. 1 2 · The safety switch tripping as described in claim 1 wherein the contact piece is formed into a curved body by an external force, and can be bounced toward the two sides. 1 3· As claimed in claim 1, the safety switch is tripped and interlocked, wherein the contact piece is a composite metal foil, and when heated, one side is deformed to one side opposite to the plurality of sidewalks, so that the structure of the structure on the fixed track 'Bend.
