Preferably, direction as shown in Figure 3, the front side of the first fixed plate positioning bar 271 set the second fixed plate positioning bar 272, the top of the second fixed plate positioning bar 272 front side sets the fixed plate locating groove coordinated with the grab 75 of fixed plate 7, and it is fixed to make The cooperation of position plate 7 and relay base 2 is relatively reliable.

As shown in Fig. 2 first group of still positioning bar group top and the second group of leader positioning bar group of the relay base 2 Top respectively sets a coil positioning bar 23, and the top of coil positioning bar 23 sets the coil positive stop lug boss with coil rack 31 to match somebody with somebody The coil locating slot of conjunction, yoke neck 230 is set between first fixed plate positioning bar 271 and the second fixed plate positioning bar 272, the The holding of the 4th plate 331 of the first plate 321 and the second yoke 33 of one yoke 32 in yoke neck 230 and with moving armature component 4 Moving armature 42 coordinate, the first axis hole 254, the first axis hole 254 and moving armature are set between two the first fixed plate positioning bars 271 The first rotating shaft 44 of component 4 coordinates.

Preferably, as shown in Fig. 2 the bottom of the relay base 2 is additionally provided with a plurality of reinforcement, further reinforcing relay The structural stability and reliability of pedestal 2.

Preferably, as shown in figs. 1 and 4, the side side edge of lid 1 sets the transmission with push card 5 horizontal on the relay The push card positive stop lug boss 11 that beam 50 is slidably connected, the free end end and the upside of transmission crossbeam 50 of push card positive stop lug boss 11 It is connected, the push card brace rod 251 of push card positive stop lug boss 11 and relay base 2 coordinates limitation push card 5 to its width side To movement, avoiding push card 5, bounce departs from the situation of push card brace rod 251 and occurred upwards in the course of the work.

Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
