Can know other advantage of the present invention and feature more below by detailed description with the accompanying drawing, these accompanying drawings provide as just example, wherein:
Fig. 1 is the perspective view that the rear portion of die casting box-type circuit breaker is shown;
Fig. 2 is the perspective view of binding post that the specific embodiment of jockey of the present invention is shown;
Fig. 3 is according to another embodiment of the present invention, and the perspective view that has the binding post of protecting screen among the last figure has been described;
Figure 4 and 5 are respectively schematic diagram and the profile that the binding post in the above-mentioned accompanying drawing is shown; With
Fig. 6 is the fragmentary, perspective view at circuit breaker rear portion, and wherein the contactor of circuit breaker is electrically connected with joint.
The box-like circuit breaker D of a die casting as can see from Figure 1, it is shaped as four utmost point shapes, and this circuit breaker is used for household electrical appliance or industrial electrical equipment.On two relative big panels (only seeing a panel 1 among this figure) of this housing four wiring column compartments 2,3,4 and 5 are arranged all.Four chambers on that panel that circuit breaker D does not illustrate in the figure are equipped with four electrical network plates of circuit breaker successively, and four chambers 2 to 5 on that panel 1 that illustrates on the circuit breaker D are equipped with four load board 6 to 9 successively.
Usually with the load wiring post load board 6 to 9 is linked to each other with the outer protection electric current, same, with the electrical network binding post electrical network plate is linked to each other with power grid cables.Described binding post is contained on the installation site in the respective compartments.
In Fig. 1, can see like this, load wiring post 10 to 13 is housed in the load cell 2 to 5.Each load wiring post 10 to 13 constitutes by metal derby 14, and metal derby is roughly parallelepiped, and an elongated channel 15 is by described metal derby, and the contactor of circuit breaker D 6 to 9 extends in channel interior.The shape of each chamber 2 to 5 is basic identical with the profile of metal derby 14, thereby after metal derby 14 inlet chambers 2 to 5, metal derby is maintained static in vertical direction.Can also see in the figure, on the one hand each chamber 2 to 5 have two with two opposite flank 2a and the contour auxiliary tank 16 of 2b, 17, these two grooves are convenient to binding post is taken out (for example using instrument), each chamber also has two auxiliary tanks 18 and 19 that are used to install dish shape nut 20 on the other hand, and this will be introduced below.A threaded hole 21 is arranged at the top of each metal derby 14, and binding post screw rod 22,23 is screwed into the back by this hole.The binding post screw rod 22 of first Room 2 has the end 22a of protrusion, and the screw rod 23 of second Room 3 preferably utilizes inlaying process and a binding 24 to link together.
According to a preferred embodiment of the invention, particularly shown in Fig. 2 to 5, four pawls 25 to 28 of guiding contactor 6 into are arranged on four angles of this quadrangle binding 24.
These four pawls 25 to 28 cooperate with otch 29 to 32 in the corresponding contact device 6, the shape complementarity of the shape of described otch 29 to 32 and pawl 25 to 28, and these otch are facing to these pawls.
Like this, when being furnished with the screw rod 22 of band protruding end 22a on these binding posts, these binding posts are used for fixing aluminium matter cable, and when being furnished with the plate 24 of band pawl 25 to 28 on these binding posts, these binding posts are used for fixing copper cable or composite cable.
Referring now to Figure 4 and 5,, the binding post of being seen that has plate 24 23 also is furnished with an anti-electric protection screen 33.This screen 33 is made by L shaped plastic sheet, and one wing 33a can be freely after being inserted between plate 24 and the binding post top 34 rotates around the lower beam portion of screw rod 23, and both wings 33a, another wing 33b among the 33b extends to binding post top.Should be anti-electric protection screen 33 cooperate with the opening of opening on terminal cover plate 41 with respective shapes 40 (in Fig. 1, can see); the terminal cover plate is in the cable end piece place at circuit breaker rear portion; so just can be according to the anti-electricity of the method for back, to satisfy the requirement of IP2 regulation.
Mainly referring to Fig. 6, a wing nut 20 that is contained in contact plate 9 belows and a cover 42 is fixed on the described contact plate 9 is introduced in the following groove 18,19 of a chamber 5 in the chamber 2 to 5 now.For this reason, had two holes 43,44,, this screw rod has been screwed among the hole 20b of wing nut 20 so that the standing screw 50 of the cover 42 on the plate 9 is passed through at contactor 9 and 5 bottoms, chamber.
In Fig. 1 and 6, on two relative big panels (only seeing a panel 1 among this figure) of Shell of circuit breaker latch 46 is housed, this latch is the power devices of indicator light (not shown) one class by fast-assembling terminal block 47, and indicator light is used for proof voltage or no-voltage.
The groove 18,19 that is noted that fixing mosaic set 42 is fixedly copper rod or other connection assist also.
Be noted that binding post and screw rod are preferably made of aluminum.
Note also that in circuit breaker shown in Figure 1, all contactors all have otch.
Below the operating process that circuit breaker is connected with the exterior protection circuit will be described simply.
In the infield, above-mentioned binding post to be introduced in each chamber 2 to 5, the contactor 6 to 9 of these chambers is used for being connected with cable.When cable is aluminium matter cable, load onto some overcoats preferably for the screw rod 22 that has protruding end 22a.The otch of being opened in position 6 to 9 29 to 32 has good contact effect.
When cable is copper cable or composite cable, the plate 24 of band pawl 25 to 28 is housed on the screw rod 23.Standing screw 23 just can be introduced the pawl of plate 24 in the otch 29 to 32 of contactor 6, and cable also just is fixed between plate 24 and the position 6 like this, and contact effect herein is fine.Equally, screw rod 23 causes that the screen 33 that is clipped between metal derby 14 and the cover plate 41 moves down fixedly the time, blocks respective openings 40 on the terminal cover plate 41 until this screen 33, thereby realizes and the electric insulation of binding post outside, satisfies the requirement of IP2 regulation.Be noted that and cooperate by the notch 41b that forms on the track 41a on the cover plate 41 and the housing the rear portion of cover plate 41 predetermined fixed to circuit breaker.
In order to connect mosaic set 42, copper rod or other connection assist, as long as screw rod 50 is passed through on cover 42, position 6 (on the nut 20) and four holes 51 of the bottom of chamber 5 respectively, 43,20b, 44, just can introduce groove 18 down to wing nut 20, in 19, described cover 42 is fixed on the contactor 9 with bolt.
Thereby the device that utilizes the present invention to obtain can link to each other contactor 6 to 9 quickly and easily with the various conductors in outside: copper cable, aluminium cable, composite cable, cover or rod etc.
Certainly, the present invention is not limited to the above-mentioned embodiment that only provides as an example.
Otherwise, the present invention includes equivalent technical solutions of the said equipment and their combination, prerequisite is that these combinations are all in spiritual scope of the present invention.
