Below with reference to accompanying drawings, describe in detail according to lower inlet wire plug-in earth leakage circuit-breaker of the present utility model." left side ", " right side ", 'fornt', 'back', "up" and "down" when " left side ", " right side " in specification, 'fornt', 'back', "up" and "down" direction refer to that earth leakage circuit-breaker is arranged on power distribution cabinet.
Fig. 1 has totally shown the three-dimensional view of looking up of plug-in earth leakage circuit-breaker (hereinafter referred to as earth leakage circuit-breaker) 1 according to an embodiment of the present utility model.As can be seen from Figure 1, this earth leakage circuit-breaker 1 comprises upper shell 2 and lower house 3, and entrance hole 4 is arranged in bottom surface.
Fig. 2 has totally shown according to the rear perspective view of the earth leakage circuit-breaker 1 of an embodiment of the present utility model.As can be seen from Figure 2, this earth leakage circuit-breaker 1 in the back upper end also comprises metal claw 5, and lower end comprises stationary jaw 6 in the back.This metal claw 5 is used as leading-out terminal, and together with stationary jaw 6, for earth leakage circuit-breaker 1 is fixed in distribution box.
Fig. 3 is the left view of earth leakage circuit-breaker 1; from Fig. 3, can more clearly find out; the housing of earth leakage circuit-breaker 1 of the present utility model adopts up-down structure; along the fore-and-aft direction shown in figure, by upper shell 2 and lower house 3, formed; rather than as common earth leakage circuit-breaker, housing adopts left and right structure.Fig. 4 is the partial sectional view of the demonstration metal claw 5 of Fig. 3.The metal claw 5 of earth leakage circuit-breaker 1 of the present utility model is metal clips; it comprises pawl end, and with the opposite end relative with pawl end, described opposite end is positioned at housing; for being connected with litzendraht wire 10, it stretches pawl end outside housing for directly clamping the bus bar that is connected to distribution box.Installation for the ease of metal claw 5 in housing, is also provided with guiding wall 9 and boss 11 in lower house 3.In Fig. 4, also shown brace 12, for being connected with the end relative with metal claw of litzendraht wire 10.
Fig. 5 is the three-dimensional view for the side pressure sheet 7 of metal claw 5, and Fig. 6 is the sectional perspective view of the show internal structure of upper shell 2, and a series of auxiliary compressing tablets 8 as can be seen from Figure 6, for coordinating and fix metal claw 5 with the side pressure sheet 7 shown in Fig. 5.
To with reference to Fig. 4,5 and 6, the fixing and installation of metal claw 5 in housing be described below simultaneously.First by metal claw 5 through in being arranged on after earth leakage circuit-breaker, be also lower house 3 below in hole, stretch in lower house 3, in place by the guided placement of guiding wall 9.The two ends of litzendraht wire 10 are connected with metal claw 5 and brace 12 respectively.Then by the vertical arm of brace 12 against boss 11, side pressure sheet 7 comprises two supporting legs 701,702, straddle on the vertical arm that is pressed against brace 12, and side pressure sheet 7 is by two supporting legs 701,702, and metal claw 5 is gripped.Finally, upper shell 2 is fastened on lower house 3, in this embodiment, auxiliary compressing tablet 8 on upper shell 3 is divided into two groups, each group coordinates with a side pressure sheet respectively, on auxiliary compressing tablet 8, is provided with recess, when upper shell 2 and lower house 3 engage, recess on one group of auxiliary compressing tablet 8 is bonded on respectively two supporting legs 701 and 702 of side pressure sheet, and metal claw 5 is fixed and installed in place.
Fig. 7 is that its earth leakage circuit-breaker based on common upper incoming line, lower outlet is realized according to the front view after the removal upper cover 2 of earth leakage circuit-breaker 1 of the present utility model, has shown the mode of connection of power line 15.This embodiment carries out on common, designs on the basis of the earth leakage circuit-breaker of lower outlet.Conventionally, in order to guarantee fail safe, when earth leakage circuit-breaker is disconnected, the integrated circuit board component of earth leakage circuit-breaker answers no-voltage to add thereon, therefore, should all the time integrated circuit board component be connected to outgoing line side.As can be seen from Figure 7, in order to realize the lower wiring patter in the present embodiment, integrated circuit board component must upwards go between with butterfly winding mode by power line 15, is connected with the outgoing line side of earth leakage circuit-breaker 1.Like this, by coordinating of moving contact and fixed contact, according to whether existing electric leakage situation open circuit or holding circuit to connect.In the present embodiment, power line 15 is connected to fixed contact, and brace 12 can be used as fixed contact.
Fig. 8 is according to the cutaway view of the stationary jaw 6 of earth leakage circuit-breaker 1 of the present utility model, and as seen from the figure, stationary jaw 6 is integrally formed with lower house.
Because earth leakage circuit-breaker 1 of the present utility model utilizes metal claw 5 and stationary jaw 6, be directly fixed on bus bar and distribution box, therefore earth leakage circuit-breaker 1 of the present utility model, without taking left and right structure, adopts up-down structure.And upper shell 2 and 3 of lower houses need be by snap engagement, without further riveted joint.Described snap engagement can adopt any structure as known in the art.
Above-described embodiment is that following inlet wire plug-in earth leakage circuit-breaker is realized.Such as, because the superior and the subordinate that coordinate with earth leakage circuit-breaker at present adopt the Protector for electric appliances (overload protection circuit breaker etc.) of upper incoming line, lower outlet substantially; therefore; while being connected at the same time in distribution box; for the ease of the wiring of the lower outlet of higher level's protective device; earth leakage circuit-breaker in the present embodiment adopts lower wiring patter, and which has also been saved the wiring space in distribution box simultaneously.
Certainly; according to earth leakage circuit-breaker of the present utility model, can not necessarily adopt as required lower wiring patter; metal claw is also not necessarily as leading-out terminal; that is to say; if needed; lower entrance hole can be used as wire hole, and metal claw can be used as end of incoming cables, only should be noted and guarantees that integrated circuit board component is connected to outgoing line side.
And; according to the earth leakage circuit-breaker 1 of the present embodiment, without the internal part of the earth leakage circuit-breaker of the upper incoming line to prior art, lower outlet, do large adjustment; only need add metal claw 5 as leading-out terminal; when housing is molded, be integrally formed stationary jaw 6; and lower inlet wire is passed through to lead-in wire; make surface-mounted integrated circuit electrical component be connected to outgoing line side, can realize lower inlet wire plug-in earth leakage circuit-breaker 1.
Further, the present embodiment can be designed to other alternate embodiments as required, for example, end of incoming cables and leading-out terminal all can be set to metal claw, thereby avoids wiring trouble, and without stationary jaw 6.
Should understand, shown execution mode is only exemplary, should not think that, to restriction of the present utility model, scope of the present utility model is only defined by the following claims.Can to shown in execution mode make various deformation form and improved form and do not depart from scope of the present utility model.
