Abstract
The utility model discloses a support part of a conductive spring plate, which mainly comprises a conductive spring plate and a support part; wherein the conductive spring plate with one end fixed and the other end free can spring towards two side surfaces; the support part is arranged on one side of the conductive spring plate and not in contact with the conductive spring plate; and the support part and the conductive spring plate are perpendicular to each other. When the current is conducted and the temperature of the circuit loop is over heat, the heated conductive spring plate is extended and deformed, so that the side surface of the conductive spring plate is pressed against the end of the support part, the support part applies a reacting force to push the conductive spring plate to be in contact with the side surface, and forces the conductive spring plate and the free end thereof to spring towards the other side surface, so as to interrupt the electrical loop and ensure a power off condition.
Description
Technical field
The utility model relates to a kind of supporting piece structure of electroconductive elastic sheet, relates in particular to a kind of supporting piece structure that is applied to the electroconductive elastic sheet of mains switch or circuit breaker.
Background technology
Various mains switch of the prior art or breaker structure, its major function are, form energising (ON) and outage (OFF) two kinds of actuating lengths of circuit loop.Mains switch loop structure of the prior art, with reference to figure 1 and Fig. 2, utilize an electroconductive elastic sheet 201, these electroconductive elastic sheet 201 1 ends and the first terminal 202 are electrically connected, the free end of electroconductive elastic sheet 201 is established first contact 203, this first contact 203 is corresponding to second contact 205 on second terminal 204, by second contact, 205 contacts of first contact 203 of electroconductive elastic sheet 201 and second terminal 204 or separate, and forms the energising (ON) or the outage (OFF) of circuit loop.
Aforementioned mains switch loop structure of the prior art, in order to avoid continuing energising when the current overload, and cause the danger that circuit is overheated or electric wire cocks off, this electroconductive elastic sheet 201 is normally made with alloy piece, and group is made as bending a little, bounces in being heated back distortion and energy back-flexing; During energising, electroconductive elastic sheet 201 keeps direction (downwards) bending to second terminal 204, the circuit loop that second contact 205 of electroconductive elastic sheet 201 free-ended first contacts 203 and second terminal 204 is kept in touch (ON) state of switching on, as shown in Figure 1; When current overload, electroconductive elastic sheet 201 temperature distortions and oppositely (make progress) bending and bouncing, make electroconductive elastic sheet 201 free-ended first contacts 203 and second contact 205 be separated into the state of outage (OFF), as shown in Figure 2, can make the electronic product of circuit loop and electrical communication avoid overheated and burn, guarantee the demand for security of electricity consumption.
Though, the electroconductive elastic sheet 201 of mains switch loop structure of the prior art is made with alloy piece, the metal that comprises at least two kinds of different coefficients of expansion in theory can be because of coefficient of expansion difference extensional deformation in the back two kinds of metals that are heated, should be all can back-flexing and bounce.Yet on actual the use, the shortcoming of its generation is:
When (a) making electroconductive elastic sheet 201, because the differences such as metal ingredient ratio difference of thickness, width, length and each batch of electroconductive elastic sheet 201, and thickness, flexibility and the architectural characteristic that can't guarantee each sheet electroconductive elastic sheet 201 are identical, this become the change that influences the stretching, extension of electroconductive elastic sheet 201 when being heated temperature rise, distortion and back-flexing spring because of; So be difficult to effectively control electroconductive elastic sheet 201 in the reaction temperature value of back distortion and back-flexing spring of being heated, the temperature value error of setting induction is bigger.
(b) electroconductive elastic sheet 201 is not high in the acuity of be heated back distortion and back-flexing spring, when overload is overheated, can't reach the protection of expection in time at the temperature threshold value escape of setting usually.
(c) electroconductive elastic sheet 201 escapes are incomplete, make circuit still be current conductive state, and it is overheated that electric power loop continues.
When (d) the current overload circuit was overheated, electroconductive elastic sheet 201 was half escape state, rebound "on" position more again when electroconductive elastic sheet 201 cooling, and the formation spark that continues to switch on repeatedly, cuts off the power supply causes danger; And the electronics in the overall current loop, electric equipment cause the electric current instability because of switching on repeatedly, cutting off the power supply, and cause when machine or can't normal operation, shorten useful life, even infringement fully.
Therefore, solving aforementioned these electroconductive elastic sheet 201 temperature distortions and oppositely escape outage and the critical temperature of effectively controlling electroconductive elastic sheet 201 escapes, is the major issue of mains switch loop safe handling.
