Referring now to Fig. 4 to Figure 11,, can see that arrangements of electric connection E according to the present invention comprises an accessory 9 for each electric conductor 3, design is used for linking to each other with lead-out terminal 2.These accessories 9 are fixed in one and are called as in the supporting member 10 of second supporting member.Supporting member 10 can be installed in the first above-mentioned supporting member 4 linearly, perpendicular to the longitudinal axis of guide rail, and is parallel to the installed surface of equipment on guide rail under the mounted state of equipment.Each accessory 9 includes second parts that first parts 11 and that are used to be electrically connected accessory 9 and respective terminal 2 are used to be electrically connected described accessory 9 and corresponding electric conductor 3.
To the embodiment of the invention shown in Figure 7, these first parts 11 comprise a flat brace 13 according to Fig. 4, and this brace 13 is electrically connected and is fixed on the binding clip 14 of U-shaped roughly.The binding clip 14 of U-shaped has constituted second parts 12 of accessory 9.This brace 13 is designed to insert the screw terminal 2 of circuit-breaker D, and is clamped in terminal 2 on the corresponding brace 15 of circuit-breaker D, as institute is known fully.Aforementioned binding clip 14 comprises the 14a of branch, 14b (accompanying drawing 4), and between these two 14a of branch, 14b, the end of the electric conductor 3 of differential unit B is designed to be clamped by deformable ground, thereby forms sliding contact with electric conductor 3.
In Fig. 8 to Figure 11, two parts 11,12 form by U-shaped binding clip 16,17, and a binding clip is arranged on another the inside, as among Fig. 8 in more detail as described in.Binding clip 16 is called as first binding clip owing to it constitutes first parts, comprises a bottom 16a.Binding clip 17 is called as second binding clip owing to it constitutes second parts, and its bottom 17a is fixed on the 16a of bottom.Binding clip 16 also comprises two 16b of branch, 16c, their end 16d, 16e is equipped with an interior convex portion a, b is to be matched with the two sides c of the brace end that belongs to circuit-breaker D, d (accompanying drawing 10), thereby after attended operation was finished, that just can set up automatically, determine between the brace 15 of the electric conductor 3 of differential unit B and the respective terminal of circuit-breaker D be electrically connected.The binding clip 17 that is called as second binding clip is fixed in the inside of first binding clip 16, makes the bottom 16a of the two, and 17a is connected, the 17b of branch of second binding clip, and the 16b of branch of the 17c and first binding clip, 16c extends in parallel.In the aforementioned embodiment, second binding clip 17 is used to be engaged on the electric conductor 3 of corresponding differential unit B, to form sliding contact with electric conductor 3.
Below, referring to Figure 11 and Figure 12.As can be seen, second supporting member 10 comprises a screw cover 18, and this screw cover 18 and second supporting member 10 are molded together, and comprise kayser parts 19, is used for described supporting member 10 is locked in supporting member 4.Above-mentioned parts comprise a grab 20, and this grab 20 and lid 18 are molded together and can be engaged in the recess 21 that the supporting members 4 of differential apparatus are used for being engaged with.
Below, in conjunction with the accompanying drawing of above-mentioned two embodiment, the attended operation of two equipment is described.
At first, two equipment D, the B move toward one another until the panel 5,6 of the opposite face of the two near and be meshed and mechanical connection (accompanying drawing 2) with bonded block on another equipment by the bonded block 7,8 on the equipment.Under this position, accessory 9 is facing to the lead-out terminal 2 (accompanying drawing 5) of circuit-breaker D.Then, finish electrical connection (accompanying drawing 3) by lead-out terminal translation second supporting member 10 in first supporting member 4 to circuit-breaker.Like this, for described first embodiment (Fig. 4-Fig. 7), the first, corresponding to each accessory 9, brace 13 is engaged on the brace 15 of circuit-breaker D, the second, sliding contact 14 is engaged on the corresponding main electric conductor 3.Should be noted that second supporting member 10 has constituted a button, can drive this button accessory is moved to the second place from primary importance.In first embodiment, tighten terminal screw 2a and will stop attended operation.(among Fig. 8-Figure 12), moveable support 10 at first makes first binding clip 16 be engaged in corresponding brace 15, just needn't just can finish connection by any other operation, and such engagement is determined at described second embodiment; Secondly, make the sliding contact of binding clip 17 forms be engaged in corresponding main electric conductor 3.In described second embodiment, when moving second supporting member 10, make and cover 18 and be fixed on this position in the face of the hole 2b (Fig. 7,9,10,12) of terminal screw 2a and by recess 21 (accompanying drawing 12) with grab 20 insertion respective support 4.
In the above-described embodiments, main electric conductor is connected to accessory by sliding contact.Can also imagine the connection of other types, for example, braid over braid, perhaps the situation for low rated value can be suitable for fexible conductor more simply.
Similarly, in the above-described embodiments, second supporting member can be installed linearly with respect to first supporting member, still, also can imagine, second supporting member is rotatably mounted in first supporting member or is not only rotatable but also can install linearly.
According to another embodiment, do not use the screw mode to connect.This embodiment is not shown in the accompanying drawing.Wherein, described accessory is not formed by two binding clips, but constitutes by a binding clip and a brace.Described binding clip is designed to be able to cooperate with corresponding main electric conductor, and brace can firmly be fixed on another binding clip on the corresponding brace of circuit-breaker and matches with this another binding clip by inserting.
According to another embodiment, described accessory is formed by two binding clips that combine by the rigid conductive body.
According to another embodiment that can realize automatically, determine connect, first parts can be formed by a spring, and this spring is pressed in electric conductor on the lug plate by acting on pressure on the lug plate or the bottom by the pressure splicing ear.
The present invention is specially adapted to particularly modular electric equipment, and these electric equipments closely are installed on the mounting guide rail mutually, and is designed to be electrically connected.
So because recoverable accessory is provided, the present invention can simply move along two orthogonal directions machinery, the electrical bond of realization equipment room by two.These accessories can need not to use screw just can realize connecting, and for example insert type connects.Such connection guarantees that all electric conductors can both be electrically connected well, and does not need the operation of tightening that replenishes.Therefore, formed reliable electrical connection that has nothing to do with the user, this electrical connection just can access by the connection of machine components very easily.
In addition, use these accessories can be according to the type of circuit-breaker, for same terminal position layout, by revising the shape of accessory simply, different alternative connection end that just can the adaptive circuit circuit breaker.Equally, by changing the shape of accessory, can adapt to different alternative connection configuration, wherein, terminal position is different, causes being particularly suitable for postponing differential scheme like this.
Under the situation of having selected the screw terminal scheme, provide lid can prevent to connect and be subjected to the destruction that the screw accident is tightened.When having selected screw terminal, a movable screw cover (Fig. 5-7) is hinged on the supporting member 4, and extra insulation protection is provided.
The latch system that covers may come off differential unit hardly.
A system can also be provided, can make mechanism's interference of second supporting member and circuit-breaker or differential unit, thereby this mechanism is locked under the open position up to having finished electrical connection.
