Embodiment
Known a kind of electric overcurrent relay that is similar to electric overcurrent relay described herein (it can be assembled into switchgear assembly by connective conductor and guard member) from file DE 10 2,008 062 250 A1; Therefore, this document should and cover in the disclosure of the present utility model aspect this overcurrent relay and guard member interaction in the function of overcurrent relay and basic structure.
Fig. 1 has shown view according to overcurrent relay of the present utility model, modular construction and the program (Vorgehen) when final installation that can see equipment from this view in the mode of exploded view.
Be assembled by lower member 1, upper-part 2, terminal covering members 4 and connective conductor covering members 5 according to overcurrent relay of the present utility model.
The structure of lower member 1 further is illustrated among Fig. 2, the structure of upper-part is illustrated among Fig. 3 and Fig. 4, wherein, the structure that is encased in the mounting bracket 3 in the upper-part 2 shown in Figure 5, and the structure that is encased in the adjusting mechanism 7 in the mounting bracket 3 shown in Figure 6.
Therefore, the order when installing according to overcurrent relay of the present utility model is as follows.At first assemble adjusting mechanism 7.After this, this adjusting mechanism 7 is as the module of preproduction and other component-assembled and become mounting bracket 3.Mounting bracket 3 is encased in the upper-part 2 jointly as the module and other the member of preproduction.Meanwhile, lower member 1 is formed by its one-piece unit.Assemble lower member 1 and upper-part 2 this moment.This moment lay terminal covering members 4, and in connective conductor 10,10 ', 10 " side edge lay connective conductor covering members 5.
Terminal covering members 4 is implemented as the form of half housing that has stepped profile.Produce the positive side 42 of preceding positive side 41 and back that connects by narrow side 43 thus at these terminal covering members 4 places.At narrow side 43 places-invisible in Fig. 1, because four insertion openings of the wire conductors that is blocked-is used for are positioned at auxiliary contact binding post 14,14 ', 14 "; 14 " ' to locate, these four are inserted openings by five insulation ribs 44,44 ', 44 ", 44 " ', 44 " " be separated each other.In order to make near auxiliary contact binding post 14,14 ', 14 ", 14 " ' trip bolt 16,16 ', 16 ", 16 " ' become possibility, in the positive side in back, introduce four near opening 15,15 ', 15 ", 15 " '.
There is seal buckle 45 in vertical seamed edge place on the side direction of the positive side 42 in back.
In addition, in the positive side 42 in back, exist the opening 46, the opening 47 that is used for indication piece and test groove that are used to stop key, be used to the opening 49 adjusting the opening 48 of button and be used for button 50.
Sealing covering members 51 can be inserted in (Taschenartig) recess (Ausnehmung) (this recess extends away from seal buckle 45 on the right side in the positive side 42 in back) of pocket-shape.Sealing covering members 51 has approximate T shape, and wherein, vertically bridging piece 52 is as hiding indication piece and test function part (Testfunktion).Laterally bridging piece 53 has otch 54, has index face
But backplate 55 interlocks (einschnappen) of rectangle in this otch 54.For this reason, backplate 55 has fixedly rib (Befestigungsrippe) at its vertical side place, but this fixedly rib hasp (einrasten) in the corresponding grooves in vertical seamed edge of otch 54.At its narrow side place towards seal buckle 45, laterally bridging piece 53 has the opening 56 that is used for seal buckle 45, and seal buckle 45 salable (plombieren) is in this opening 56.Sentence the mode of downward sensing in identical narrow side, latch 57 is molded into sealing covering members 51 places, and this latch 57 is formed for being molded over the stop of the alignment pin automatic/hand at button 50 places.
Locate to be mounted with connective conductor covering members 5 in so narrow side of lower member ( connective conductor 10,10 ', 10 " stretch out) at this narrow side place.Connective conductor covering members 5 has insulating case 61,61 ', 61 "; this insulating case 61; 61 ', 61 " partly so hold connective conductor and protect connective conductor to avoid contact, promptly; the binding (Ankopplung) with the electricity of the guard member that is used for and is added is exposed in the feasible only end block of connective conductor (Endst ü ck) maintenance; in addition, this connective conductor covering members 5 externally has two hooks 62,62 '; utilize these two hooks 62,62 ' can mechanically keep the guard member of being added.
Before laying the connective conductor covering members, the narrow side (connective conductor at this narrow side place outstanding) that is in this lower member 1 in lower member 1 is located to pack into and is triggered the guide plate component parts
(it comprises driver plate 63 (being also referred to as the upper guide plate element), underdrive plate 64 (being also referred to as the bottom guide element), and transmission levers 65 (being also referred to as linkage element)).This triggering guide plate component parts causes open phase protection (Phasenausfallschutz) by the bimetal leaf of putting in lower member 1 when heat triggers; that is to say; this triggering guide plate component parts guarantees, when three in mutually one are interrupted and only on one or two of remaining phase correspondingly high overload current arranged
When flowing through, then the switching mechanism of overcurrent relay triggers.Trigger structure, the principle of work and power of guide plate component parts 63,64,65 and be attached to that bimetal leaf is sentenced and in file DE 10 2,008,062 527 A1, describe in greater detail with influencing each other of bimetal leaf and switching mechanism.Therefore, the disclosure content should cover in the disclosure of this patent at triggering guide plate component parts 63,64,65 aspects.
At this moment, observe Fig. 2, Fig. 2 has shown the exploded view of the lower member of overcurrent relay.Lower member 1 comprises and is essentially housing 66 square, that be open upwards, is formed with three chambers that are separated each other by next door (Zwischenwand) in this housing 66.
Connecting the side place, just outlying observation person's the narrow side place in Fig. 2 of housing 66 inserts connective conductor 10,10 ', 10 ".Each connective conductor 10,10 ', 10 " have approximate L shaped shape, wherein, long limit leg has the bending of S shape.Each connective conductor is so put in the housing 66, that is, make this connective conductor weak point the limit leg upwards, on the direction that triggers assembly towards heat, pointing to.
Each of three chambers in housing 66 all is used as holds the heat trigger component parts
70,70 ', 70 " with for respectively the protection (Absicherung) phase line (Phasenleitung).Overcurrent relay is also as three-phase protective.In Fig. 2 in the trigger component parts two 70 ' and 70 ' are depicted as to finish and install and be in side by side to be used for being encased in the chamber that is respectively its setting.The 3rd trigger component parts 70 illustrates in the mode of exploded view (Sprengdarstellung), so that therefrom can find out the profile of its structure and single-piece.This bimetal leaf trigger assembly
26S Proteasome Structure and Function in file DE10 2,008 062 528 A1, describe in greater detail.Therefore, the disclosure content should be in trigger assembly 70,70 ', 70 ", its structure, function and favourable effect aspect cover in the disclosure of this patent.
Observe Fig. 3 this moment, and Fig. 3 has shown the exploded view of matrix 80 of the upper-part 2 of overcurrent relay.Matrix 80 has the basic configuration for unlimited square body at the place, both sides basically.This matrix 80 of narrow side place on the side direction of this matrix 80 respectively has two kayser hooks 81,81 ' and is connected with lower member 1 being used for.
Now, successively following part or assembly are encased in the matrix 80 of upper-part 2:
