According to another favourable design of the present invention, an encoder element of the initial code of described switching device is designed to the bar of encoding, and an encoder element of the initial code of described auxiliary switch assembly can be designed to the coding projection.
According to another favourable design of the present invention, the cover plate of switching device has a slit, and the alignment pin of auxiliary switch assembly can reach in this slit when coupling.Described coding bar and coding projection can adopt machinery or laser mode to read.
By accompanying drawing embodiments of the invention are described further below, in the accompanying drawing:
Fig. 1,2,3 is depicted as switching device, particularly contactor or auxiliary contactor, and pairing auxiliary switch assembly with different wiring numbers;
The upper shell with different coding of switching device shown in Fig. 4,5,6 presentation graphs 1,2,3, and auxiliary switch assembly base plate with corresponding coding;
Fig. 7 represents the back side of the cover plate and the 1 line auxiliary switch assembly male part of contactor or auxiliary contactor;
Fig. 8 represents the back side of cover plate and 2 lines or the 4 line auxiliary switch assembly male parts of contactor or auxiliary contactor.
Fig. 1,2,3 has respectively shown a main switch 1, for example contactor or auxiliary contactor, and it has a lower house 2, and this housing for example is fixed on the mounting rail with its bottom, and this main switch also has a upper shell 3 with front shroud 4.An auxiliary switch assembly 5 can be coupled on the cover plate 4 of main switch 1.Described auxiliary switch assembly links to each other with the contact bridging frame of a not shown main switch 1, connects by this, and when the main contacts of main switch 1 moved, the auxiliary contact of auxiliary switch assembly 5 are action simultaneously also.This connection is to realize by the opening and a unshowned Connection Element that can pass main switch 1 and auxiliary switch assembly 5.Main switch 1 particularly has a rectilinear operating mechanism.Auxiliary switch assembly 5 can have 1,2,4 line type structures as shown in Figure 1, 2, 3.
Fig. 4,5,6 has shown the upper shell 3 of a contactor 1 respectively in its underpart, shown the base plate of an auxiliary switch assembly 5 at an upper portion thereof, and the coding of described auxiliary switch assembly and upper shell 3 are complementary.The front of upper shell 3 is provided with a rectangular opening 8 in the centre of main switch 1 joining zone that characterizes by dividing plate 7, and it is used to hold described Connection Element.The both sides in hole 8 have L-shaped and upwards are the prerotation vane 9 at oblique angle, and this prerotation vane is as the male part of auxiliary switch assembly 5.Auxiliary switch assembly 5 have match with it, be positioned at the other stator 11 implementing to be connected of being used in hole 10 equally, this stator can be meshed with the prerotation vane 9 of upper shell 3 after 5 couplings of auxiliary switch assembly.Additional code bar 12 and the coding of the correspondence on the auxiliary switch assembly 5 by main switch 1 can guarantee to have only corresponding to main switch 1 of its contact configurations and auxiliary switch assembly 5 just can link together.Coding bar 12 can fracture under pressure easily, so that change coding by this mode.
Front upper in the hole 8 of upper shell 3 shown in Figure 4 has two coding bars 12, and the distance between this coding bar can make the stator 11 on the base plate 6 of auxiliary switch assembly 5 successfully enter the position of inserting prerotation vane 9.By arranged outside coding projection 13, can carry out respective coding to the auxiliary switch assembly at the stator 11 of auxiliary switch assembly 5.The coupling of auxiliary switch assembly obtains stoping by this coding projection 13 and the coding bar that is positioned on the main switch 1 of same side.Described coding projection 13 can be removed from the manufactured goods of auxiliary switch assembly 5 easily with cutting tool.
In Fig. 5, different with original 2 coding bars 12 shown in Figure 4, upper shell 3 wherein has only left side coding bar.So, coding projection 13 is not set on the left side stator 11 of the base plate 6 of corresponding auxiliary switch assembly 5, but only in the arranged outside of right side stator 11 a coding projection 13.But at this side bar 12 of not encoding, so that realize coupling.
In Fig. 6, upper shell 3 has only right side coding bar 12 and a base plate 6, has only left side stator 11 to have coding projection 13 on this base plate.
Table 2 has provided and Fig. 4,5 and Fig. 6 is corresponding has the contactor of relevant auxiliary switch assembly or an encoding relation of auxiliary contactor.
