Embodiment
In the drawings and in which, electric protection and/or distributing equipment can be seen, particularly modularized circuit breaker D, be intended to be fixed on mounting bracket such as guide rail R.This equipment is contained in the housing B of almost parallel hexahedral shape, comprise the front 1 containing nozzle N, handle M for activating this equipment is occurred by nozzle, this equipment is installed in the back side 2 on guide rail R by it, this equipment can be connected to the miscellaneous equipment of the identical type be arranged on equally on same support by it two interareas 3,4 (Fig. 5) and two sides 5, this side usually install in cabinet to be positioned at equipment above and below and be equipped with permission by this equipment connection to the parts of distribution network or other electric equipment.
Therefore, being arranged in the seat 16,17 in apparatus casing appears in the lead-in wire 34 of device interior, and can be inserted into opening 9,10 wherein by outside lead 11,12 and close.These seats comprise link, allow clamping flexibility or rigidity or other cable, have contacted electrical install to keep them with a part for the inner lead of equipment.
Contingently below be, electricity one of equipment needs to be electrically connected to two lead-in wires with identical terminal, such as wherein circuit breaker needs on side in upstream electrical is connected to differential auxiliary equipment and contacts another auxiliary equipment of type to pre-wired on another side.
Make it possible to perform this dual link (or disconnection) according to the jockey of the preferred embodiment of the present invention described herein, and comprise the part forming yoke portion 13, be mounted to slide relative to the housing of this equipment and can the given translational motion by the actuated components of the swingle 14 comprising cam 15 type be passed through.At open position, this yoke portion can be remained on open position because of fulcrum system by this cam.Therefore, two cams of two terminals arranged side by side can be activated and two yoke portions are remained on open position.This yoke portion 13 also comprises two seats 7,8 being intended to reception two lead-in wire respectively, and described seat aligns on the direction that the fixed pan P being approximately perpendicular to this equipment extends.The spring leaf 18,19 being roughly S shape is positioned at these each inside of 7,8, each spring leaf by its so-called first end one of them 20,21 and be bearing on what is called second fixed part 24,31 of join domain, and by its relative end 22,23, be known as the second end, be bearing on so-called first fixed part 24,31 of the join domain of this equipment.
For this reason, yoke portion 13 comprises the recess 25,26 towards each spring leaf, it is intended to allow to create the part 27,28 of turning back towards device interior, and this part is intended to be bearing on the so-called first end 20,21 of corresponding spring leaf, to make it possible to by yoke portion compression spring leaf.
This yoke portion 13 is formed by with the crew-served base portion 29 of the cam 15 of bar 14 and by two packing rings 30 extended from this base portion, and each packing ring 30 comprises being positioned at and is seated in above-mentioned first recess 25 on the free edge 32 of gasket end portion and the second recess 26 roughly on one of the position lateral edges being positioned at packing ring 33 of its mid-length.
Each spring leaf is relative to the opening for introducing respective lead and be placed in relative to described yoke portion and set size in this equipment, thus be in as Fig. 2 at the bar 14 of cam 15 type, during open position shown in 3 and 5, extremely for introducing the opening 9 of lead-in wire, 10 and to the opening 7 in yoke portion 13, the path of 8 is eliminated, therefore allow or introduce lead-in wire or remove described lead-in wire, and when bar 14 is in the close position, as shown in figs. 1 and 4, these openings are by the Part I 20 of described spring leaf, 21 partly block, but but really allow to introduce lead-in wire, until lead-in wire contacts with the respective regions of this equipment, then described lead-in wire is securely held in spring leaf 18, the first end 20 of 19, 21 with what is called second fixed part 24 of corresponding join domain, between 31.
Therefore, in operation, when the bar 14 of cam 15 type is in make position as shown in figs. 1 and 4, described yoke portion is in tip position, namely yoke portion does not apply any action in spring leaf 18, on 19, and when bar 14 is in as Fig. 2, during open position shown in 3 and 5, yoke portion 13 is in bottom position and compression spring leaf 18, 19, so that release opening 9 roughly completely, 10 for introducing lead-in wire 11, 12, thus allow these lead-in wires 11, the removal of 12 is even introduced, introducing although it is so can be carried out in the second place in the yoke portion of the make position of the bar 14 corresponding to cam 15 type equally, as illustrated above.
When described bar is changed to make position from open position, the pressure on described cam retracting spring sheet, it upwards repels yoke portion namely towards described bar.
Therefore, the present invention has proposed a kind of jockey, and it allows the electrical protective device being electrically connected to standard auxiliary equipment, comprises rigid leads, and it is intended to the terminal being connected to this equipment in the usual manner by screw system.
As Fig. 5 especially shown in, can find out, advantageously differential auxiliary equipment can be connected to circuit breaker according to jockey of the present invention.
The invention enables and can connect fast or one or two lead-in wire.The present invention also makes it possible to keep all elastic systems to open, can be easy to and again dismantle auxiliary equipment rapidly, because the fact the invention enables can remove all lead-in wires simultaneously.
The present invention is advantageously applicable to any equipment being necessary to connect small bore lead-in wire.
The present invention is particularly useful for having the circuit breaker at least the two poles of the earth, such as three poles and four-pole circuit breaker.
Certainly, the present invention be never limited to only provide with example described in and shown embodiment.
Therefore, the invention still further relates to a kind of jockey, it only comprises introduces opening, spring etc., is namely suitable for the electrical connection performing single lead-in wire.
In contrast, the present invention includes all technically equivalent ones and their combination of described device, prerequisite is if the latter carries out under its spirit.
