Abstract
The present invention relates to a circuit control protector which makes a link rod piece act synchronously by pushing and swinging a button to push and pull a contact piece to jump so as to make a circuit form an ON or OFF position. The present invention is characterized in that the button is provided with a buckle hole which is provided with an extending slot; one end of the link rod piece is movably connected with the contact piece, and the other end of the link rod piece is movably embedded in the buckle hole of the button. When the button is in the ON position of the circuit, the extending slot of the buckle hole provides a space for the other end of the link rod piece to freely shift. When the circuit is in the ON position, and a current is overloaded, the contact piece reversely bounces by temperature distortion and pushes the link rod piece to shift, the other end of the link rod piece is capable of freely shift in the extending slot without the obstruction of the button, and the contact piece is capable of easily bounce to form the complete OFF position of the circuit and ensure electricity usage safety.
Description
Technical field
The present invention relates to a kind of circuit-controllable protector, it is between button and interlock rod member, is provided with one and extends the space that groove provides free displacement; When current overload, the contact chip temperature distortion is oppositely bounced, and contact chip promotes this interlock rod member displacement, and the other end of this interlock rod member is able to free displacement in extension groove, not interrupted, contact chip is able to escape successfully, forms the OFF of the outage fully state of circuit loop.
Background technology
The operation of power control switch mainly is to carry out energising ON and two kinds of motion modes of outage OFF of current circuit.Except carrying out energising ON and two kinds of functions of outage OFF, existing many constructions of switch also have the function of current overload automatic escape outage when overheated, avoid the fuse of current circuit when current overload or circuit breaker can not real time reaction to cut off the power supply or the danger of escape.
Case is too numerous to enumerate before the patent of various power control switch commonly used, as the United States Patent (USP) the 5th, 262 of applicant's application, No. 748, other United States Patent (USP) the 4th, 167, No. 720, the 4th, 937, No. 548, the 5th, 223, No. 813, the 5th, 451, No. 729, the 5th, 558, No. 211 ... wait too numerous to enumerate, but case all has common shortcoming before the patent such as all, and is as follows:
The element of interlock is various, and the stroke complexity of interlock produces the non real-time movement relation between button and final element, has also improved manufacturing cost.
Movement relation is uncertain, increases the fault chance, is unfavorable for the security consideration that the consumer uses.
When the current overload circuit was overheated, contact flat spring escape outage in real time or escape were incomplete, made circuit still be current conductive state, and circuit continues overheated and causes danger.
When the current overload circuit was overheated, contact flat spring was half escape state, rebound "on" position more again when contact flat spring cools off, and the formation spark that continues to switch on repeatedly, cuts off the power supply causes danger; And the electronics in the current circuit, electric equipment be because of switching on repeatedly, cut off the power supply, and when machine or can't normal operation, shorten useful life, even infringement and can't using.
For effectively carrying out the interlock movement relation of power control switch inner member really, simplify the power control switch element to reduce cost of manufacture, guarantee to cut off the power supply to strengthen Electrical Safety in current overload real time reaction escape, the lasting research improvement of power control switch structure becomes manufacturer's important common issue.
Summary of the invention
The technical problem that invention institute desire solves:
The invention reside in that the element that solves power control switch serial verb construction commonly used is complicated, cost of manufacture is high, continuous action relation for indirectly, the reaction of interlock stroke reaches power control switch many shortcomings of fault in operation slowly, particularly solving power control switch commonly used when current overload is overheated, the OFF of escape outage in real time escape outage or escape are incomplete, cause circuit to continue the superheat state of circulation; And solve overload when overheated, and contact flat spring is half escape state, rebound "on" position more again when contact flat spring cool off, and the formation spark that continues to switch on repeatedly, cuts off the power supply causes the problem of danger.
The technological means of dealing with problems:
The present invention is a kind of circuit-controllable protector, consists predominantly of a box body, a button, a contact chip, an interlock rod member; It is characterized in that: this button is provided with the snapping hole, this snapping hole is provided with the extension groove, one end of interlock rod member is movably connected on contact chip, the activity of the interlock rod member other end is embedded in the snapping hole of button, when this button was positioned at the position of circuit turn-on ON, the extension groove in snapping hole provided the space of the free displacement of this interlock rod member other end; During enforcement, under circuit turn-on ON state, during current overload, when the contact chip temperature distortion is oppositely bounced, contact chip promotes this interlock rod member displacement, and the other end of this interlock rod member is able to free displacement in extension groove, is not subjected to the obstruction of button, contact chip is able to escape successfully, forms the OFF of outage fully of circuit loop.
The purpose and the technological means effect of invention:
The present invention is a kind of circuit-controllable protector; its main purpose is; through this button snapping hole the extension groove is set; the extension groove in this snapping hole provides the space of a free displacement of interlock Rod end; under current overload state; the contact chip temperature distortion is oppositely bounced and is promoted the displacement of interlock rod member; the other end of this interlock rod member is able to free displacement in extension groove; be not subjected to the obstruction in button and snapping hole; contact chip is able in real time, escape fully successfully; form the OFF of outage fully of circuit loop, reach aim of safe power utilization.
A further object of the present invention is, when the current overload circuit was overheated, contact flat spring reacted escape rapidly, and was complete escape off-position, avoid contact flat spring when cooling rebound "on" position more again, can not continue to switch on repeatedly, cut off the power supply forms the contact spark and causes danger.
Extension purpose of the present invention is, simplifies the element of the whole interlock of power control switch, and assembling can effectively reduce manufacturing cost easily, and prolongs the useful life of power control switch structure, reduces consumption user's expenditure.
