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 with existing circuit breaker 1 of circuit module 206 in breaker body 20, difference is, is arranged on to take out end of incoming cables chuck support 202 in frame 10 and leading-out terminal chuck support 202 ' is omitted in the present embodiment in the circuit breaker 1 of prior art.And the end of incoming cables plug 204 be arranged in the circuit breaker 1 of prior art in breaker body 20 and leading-out terminal plug 204 ', be also omitted in the present embodiment.Replaced end of incoming cables chuck 203, the leading-out terminal chuck 203 ' of prior art by end of incoming cables connector 207, leading-out terminal connector 207 ', be connected directly between respectively between end of incoming cables client child 101, leading-out terminal client child 101 ' and end of incoming cables contact liner 205, leading-out terminal contact liner 205 '.
Chuck 203,203 ' in the circuit breaker 1 of prior art, as shown in Figure 2, generally be made up of the more sheets of conductive sheet that two re-schedulings are folded, sheet like flexible element is provided with in the outside of two row's conducting strips, when sandwiching object in the middle of chuck, flexible member applies inside elastic force to two row's conducting strips, is clamped by object to make chuck.
And in present embodiment, a kind of connector 207,207 ' (as shown in Figure 4) of special construction is installed in be taken out on frame 10.According to the difference of current class, one or more connector 207,207 ' often extremely can be set.Because end of incoming cables connector 207 is identical with the structure of leading-out terminal connector 207 ', the structure of connector is described below for end of incoming cables connector 207.Connect 207 conductive component 2071, elastomeric element 2072 and support components 2073 comprising at least two panels and intersect.Better connect effect to obtain, the sheet number of conductive component 2071 can also be 2N sheet, N be greater than 1 positive integer.Elastomeric element 2072 can be sheet like flexible element the same in the chuck 203,203 ' with prior art, as the both sides adopting two panels springs to be clipped in conductive component 2071, also can adopt the mode of strip spring wrap around conductive component 2071, as long as can meet when connector 207 is subject to longitudinal power, conductive component 2071 can laterally outwards open, and elastomeric element 2072 laterally can apply the function of inside power to conductive component 2071.The various flexible members that can meet above-mentioned functions that those skilled in the art do not need creative work just can expect can be used in the present invention.The effect of support component 2073 is contained in wherein by conductive component 2071 and elastomeric element 2072, forms parts, and support conductive component 2071 and elastomeric element 2072.Although its shape is the frame of a rectangle in the present embodiment, those skilled in the art are easy to expect, if its shape can meet by conductive component 2071 and elastomeric element 2072 accommodated therein, form the effect of parts.And those skilled in the art is also easy to expect, also can omit support component 2073, is directly served as the effect of support component 2073 by elastomeric element 2072, as with the direct frame of resilient frame around conductive component 2071.
In addition, connector 207 is also fixed (by screw, not shown) on the base 102 taking out frame by the screw 2074 on support component 2073, as shown in Figure 6.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 present embodiment.Simultaneously client child 101 be fixed on by screw 103 (by screw, not shown) take out frame base 102 on and and chuck compact siro spinning technology, as Fig. 7.Certainly, client child 101 is also 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 present embodiment.
When breaker body 20 be pushed into take out frame 10 time, contact liner 205,205 ' the meeting compression connector 207,207 ' of its dynamic and static contact, it is made stressedly to open, be pressed on the liner 205 of dynamic and static contact simultaneously, between 205 ' and client child 101,101 ', make it formation circuit arrangement.The force direction of elastomeric element makes connector 207,207 ' have certain excess of stroke between dynamic and static contact and client child 101,101 ', makes them closely connect.For end of incoming cables connector 207, due to the chi structure of the conductive component 2071 of connector 207, when electric current I flows through conductive component 2071, as shown in Figure 5, the electromagnetic force direction that its current electromagnetic effect produces is also substantially identical with the force direction of elastomeric element 2072, is all the direction of F in Fig. 5.Their acting in conjunction, makes every a slice of conductive component 2071 closely be pressed on respective contact-making surface, ensure that the reliable contacts of circuit arrangement.
Be installed at busbar (not shown) and take out after on frame 10, after breaker body 20 is pushed into and takes out frame 10, end of incoming cables connector 207 and leading-out terminal connector 207 ' are clipped in client child 101 and move, between fixed contact liner, electric current is made to enter leading-out terminal busbar again (wherein from end of incoming cables busbar by circuit module 206 → leading-out terminal contact liner 205 ' → leading-out terminal connector 207 ' → leading-out terminal client child 101 ' in the contact liner 205 → breaker body of connector 207 → end of incoming cables, client child 101 → end of incoming cables, end of incoming cables, can reverse wiring, end of incoming cables and leading-out terminal are exchanged).
As can be seen from describing above, the circuit arrangement formed is compared with the circuit arrangement in existing circuit breaker, eliminate plug and these two parts of chuck support, enormously simplify structure, decrease contact point, reduce contact resistance, and reduce volume, make it in power distribution cabinet, have layout more flexibly.Because these two parts all need to be made of copper, eliminate these two parts and also just omit amount of copper consuming, reduce cost.And this improvement make use of the device in existing circuit breaker completely, without the need to otherwise designed, process any parts, also without the need to making any change to other parts of existing circuit breaker.
Describing in the execution mode process shown in figure, in order to clearly cause have employed specific term.But the disclosure of this patent specification is not intended to be confined to this particular term so selected, and is interpreted as each particular element and comprises all operations in a similar manner and the technically equivalent ones realizing similar effect.
For the some embodiments of the present invention so described, it is evident that they can change in many ways.This modification should not thought to depart from scope of the present invention, but all this improvement intentions are to comprise within the scope of the present invention.
