Accompanying drawing is intended to describe the illustrative embodiments of present disclosure, should not be interpreted into its scope that limits.Unless explicitly point out, accompanying drawing should not be considered to draw in proportion.
Embodiment
Now the present invention will be described in detail with embodiment by reference to the accompanying drawings.
Fig. 3 is the schematic diagram of the circuit arrangement of the specific embodiment of the present invention.Wherein, the same in circuit module 206 in the breaker body 20 and the existing circuit breaker 1, difference is, is arranged on end of incoming cables chuck support 202 and the leading-out terminal chuck support 202 ' taken out in the frame 10 and is omitted in the present embodiment in the circuit breaker 1 of prior art.And in the circuit breaker 1 of prior art, be arranged on end of incoming cables plug 204 and leading-out terminal plug 204 ' in the breaker body 20, also be omitted in the present embodiment.End of incoming cables chuck 203, leading-out terminal chuck 203 ' by end of incoming cables connector 207, leading-out terminal connector 207 ' replacement prior art directly are connected to respectively between end of incoming cables client's terminal 101, leading-out terminal client terminal 101 ' and end of incoming cables contact liner 205, the leading-out terminal contact liner 205 '.
Chuck 203,203 ' in the circuit breaker 1 of prior art, as shown in Figure 2, generally consisted of by the folded multi-disc conducting strip of two re-schedulings, the outside at two row's conducting strips is provided with the sheet flexible member, when in the middle of chuck, sandwiching object, flexible member applies inside elastic force to two row's conducting strips, so that chuck clamps object.
And in the present embodiment, a kind of connector 207,207 ' (as shown in Figure 4) of special construction is installed in to be taken out on the frame 10.According to the difference of current class, every one or more connectors 207,207 ' can be set extremely.Because end of incoming cables connector 207 is identical with the structure of leading-out terminal connector 207 ', the below illustrates the structure of connector as an example of end of incoming cables connector 207 example.Connect 207 conductive component 2071, elastomeric element 2072 and support components 2073 that comprise at least two intersections.In order to obtain better to connect effect, the sheet number of conductive component 2071 can also be the 2N sheet, and N is the positive integer greater than 1.Elastomeric element 2072 can be with sheet flexible member the same in the chuck 203,203 ' of prior art, as adopt two springs to be clipped in the both sides of conductive component 2071, also can adopt the strip spring is wrapped in conductive component 2071 mode on every side, as long as can satisfy when connector 207 is subject to longitudinally power, conductive component 2071 can laterally outwards open, and the function that elastomeric element 2072 can be laterally applies inside power to conductive component 2071 gets final product.The various flexible members that can satisfy above-mentioned functions that those skilled in the art do not need creative work just can expect can be used among the present invention.The effect of support component 2073 is that conductive component 2071 and elastomeric element 2072 are contained in wherein, forms parts, and supports conductive component 2071 and elastomeric element 2072.Although it is shaped as the frame of a rectangle in the present embodiment, those skilled in the art are easy to expect that as long as its shape can satisfy conductive component 2071 and elastomeric element 2072 are held wherein, the effect that forms parts gets final product.And those skilled in the art also is easy to expect, also can omit support component 2073, the effect of directly serving as support component 2073 by elastomeric element 2072, as with the direct frame of resilient frame around conductive component 2071.
In addition, connector 207 also is fixed (by screw, not shown) on the base 102 of taking out frame, as shown in Figure 6 by the screw 2074 on the support component 2073.In addition, connector 207 is not limited to this with the fixed form of taking out frame base 102, and the various conventional fixed form that those skilled in the art are easy to expect may be used in the present embodiment.Client's terminal 101 is fixed on to be connected on the base 102 of taking out frame and with chuck by screw 103 (by screw, not shown) and connects simultaneously, such as Fig. 7.Certainly, client's terminal 101 also is not limited to this with the fixed form of taking out frame base 102, and the various conventional fixed form that those skilled in the art are easy to expect may be used in the present embodiment.
When breaker body 20 is pushed into when taking out frame 10, the contact liner 205 of its dynamic and static contact, 205 ' meeting compression connector 207,207 ', make its stressed opening, be pressed on simultaneously dynamic and static contact liner 205,205 ' and client's terminal 101,101 ' between, make it to form a circuit arrangement.The application of force direction of elastomeric element makes connector 207,207 ' for having certain excess of stroke between dynamic and static contact and the client's terminal 101,101 ', and they can closely be connected.Take end of incoming cables connector 207 as example, because the chi structure of the conductive component 2071 of connector 207, when electric current I is flowed through conductive component 2071, as shown in Figure 5, the electromagnetic force direction that its electric current galvanomagnetic effect produces is also basic identical with the application of force direction of elastomeric element 2072, all is the direction of F among Fig. 5.Their acting in conjunction can both closely be pressed on separately the contact-making surface every a slice of conductive component 2071, has guaranteed the reliable contact of circuit arrangement.
The busbar (not shown) be installed to take out on the frame 10 after, when breaker body 20 be pushed into take out frame 10 after, end of incoming cables connector 207 and leading-out terminal connector 207 ' are clipped in client's terminal 101 and moving, between the fixed contact liner, so that electric current enters the leading-out terminal busbar (wherein from the end of incoming cables busbar again by circuit module 206 → leading-out terminal contact liner 205 ' → leading-out terminal connector 207 ' → leading-out terminal client terminal 101 ' in the contact liner 205 → breaker body of connector 207 → end of incoming cables, client's terminal 101 → end of incoming cables, end of incoming cables, but reverse wiring exchanges end of incoming cables and leading-out terminal).
Can find out from top description, formed circuit arrangement is compared with the circuit arrangement in the existing circuit breaker, these two parts of plug and chuck support have been omitted, greatly simplify the structure, reduced contact point, reduced contact resistance, and reduced volume, make it that more flexibly layout is arranged in power distribution cabinet.Because these two parts all need to be made of copper, and have omitted these two parts and have also just omitted amount of copper consuming, have reduced cost.And this improvement utilized the device in the existing circuit breaker fully, need not otherwise designed, processes any parts, also need not other parts of existing circuit breaker are made any change.
In describing the execution mode process shown in the figure, for cause has clearly adopted specific term.But the disclosure of this patent specification also is not intended to this particular term that is confined to selection like this, and be interpreted as the technical equivalents thing that each particular element comprises that all operate and realize similar effect in a similar manner.
Some embodiments of the present invention for so having described it is evident that they can change in a lot of modes.This modification should not think to depart from scope of the present invention, but all this improvement intentions are to comprise within the scope of the present invention.
