Abstract

The present invention relates to a circuit control protector which pushes and pulls a contact piece to bounce by pushing a button to swing so as to make a circuit form an ON state or an OFF state. The button is provided with a control rod assembly which comprises a pull rod and a push rod, wherein the contact piece is movably held between the draw rod and the push rod. When the circuit control protector is operated, the pull rod of the control rod assembly pulls the contact piece or the push rod of the control rod assembly pushes the contact piece to make the contact piece bounce so as to form the ON or the OFF of the circuit. When the button is in an ON position, the push rod rotates at an angle to make a section of bounce space delta S between the push rod and the contact piece. The bounce space delta S provides a space for the contact piece to freely shift to the direction of the push rod. When a current is overloaded, the contact piece reversely bounces due to temperature distortion, so that contact piece can deform and easily bounce to form the complete OFF state of the circuit and ensure the safety of electricity utilization.

Description

Circuit-controllable protector

Technical field

The present invention relates to a kind of circuit-controllable protector; it is to utilize button interlock one control rod member group; when the state of energising (ON); the push rod displacement of this control rod member group is rotated; make to form one section bounce space Δ S between push rod end and the contact chip, when current overload, this bounce space Δ S provides the path of contact chip reversal deformation spring; contact chip is able to escape successfully, forms outage fully (OFF) state of circuit loop.

Background technology

The operation of power control switch mainly is to carry out energising (ON) and outage (OFF) two kinds of actuating lengths of current circuit.Except carrying out energising (ON) and outage (OFF) two kinds of functions, 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 various patents of commonly using power control switch, the United States Patent (USP) of applying for as the applicant the 5th, 262, 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 ... etc. too numerous to enumerate, but case all has common shortcoming before these patents, and is as follows:

1. the element of interlock is various, and the stroke complexity of interlock produces the non real-time action relationships between button and final element, has also improved manufacturing cost.

2. the start relation is uncertain, increases the fault chance, is unfavorable for the security consideration that the consumer uses.

3. 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.

4. 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 make the machine can't normal operation, shortens useful life, even infringement and can't using.

For effectively carrying out the interlock action relationships 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 by the immediate reaction escape when current overload, the lasting research improvement of power control switch structure becomes manufacturer's important common issue.

Summary of the invention

The invention reside in and solve that the element commonly use the power control switch serial verb construction is complicated, cost of manufacture is high, continuous action relation is indirect, the reaction of interlock stroke reaches power control switch shortcoming more than the fault in operation slowly, particularly commonly use power control switch when current overload is overheated in solution, (OFF) escape outage of escape outage in real time 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 present invention is a kind of circuit-controllable protector, consists predominantly of a box body, a button, a contact chip, a control rod member group; Wherein, this button winding one control rod member group, this control rod member group comprises a pull bar and a push rod, one contact chip of clamping versatilely between this pull bar and the push rod, during action, the button interlock should control rod member group, and the pull bar pulling contact chip or the push rod ejection contact chip of control rod member group are beated contact chip and formed the outage (OFF) or the energising (ON) of circuit; When button is positioned at the position of energising (ON), this push rod rotates an angle, make and form one section bounce space Δ S between push rod end and the contact chip, this bounce space Δ S provides the space of contact chip to the free displacement escape of direction of push rod, during current overload, the contact chip temperature distortion is oppositely bounced, the push rod clamping restriction of uncontrolled rod member group, contact chip is out of shape also escape successfully, forms outage fully (OFF) state of circuit loop.

The present invention is a kind of circuit-controllable protector, its main purpose is, pull bar and push rod clamping versatilely one contact chip by control rod member group, during action, the button interlock should be controlled the rod member group, the pull bar pulling contact chip or the push rod ejection contact chip of control rod member group are beated contact chip and are formed the outage (OFF) or the energising (ON) of circuit; When button is positioned at the position of energising (ON), this push rod rotates an angle, make and form the space that one section bounce space Δ S provides one section free displacement escape of the direction to push rod of contact chip between push rod end and the contact chip, during current overload, contact chip be heated reversal deformation and reverse escape, unrestricted, outage fully (OFF) state of formation circuit loop reaches aim of safe power utilization.

Another purpose of the present invention is, when the current overload circuit is overheated, the free escape of bounce space Δ S that contact chip utilization control rod member group provides, be swift in response, and be (OFF) state of escape outage completely, contact chip can or not continue the danger of switching on repeatedly, cutting off the power supply and forming the contact pyrophoric behavio(u)r and causing electric wire to cock off in when cooling rebound energising (ON) state more again.

Extension purpose of the present invention is, simplifies the element of the whole interlock of power control switch, and it makes assembling easily, and effectively reduces manufacturing cost, prolongs the useful life of power control switch structure, reduces consumption user's expenditure.
