Abstract
The utility model relates to an auxiliary contact head, which is arranged in a circuit breaker. When the contact head of the circuit breaker is closed or switched off, the auxiliary contact head outputs and switches signals. The utility model comprises a microswitch (4), a support piece (2) and a support rack (8). The microswitch (4) is installed on the support rack (8) by the support piece (2). The support rack (8) is fixed on the magnetic conducting plate of the electromagnetic mechanism of the circuit breaker. The microswitch (4) is contacted with the moving contact of the circuit breaker by a roller (6). A conductor wire (1) is connected with a control power source. The utility model has the advantages of small size (43 mm*18 mm*31 mm), good working reliability, etc.
Description
The utility model relates to a kind of auxiliary contact, is installed in the circuit breaker, when contact of breaker closure/disconnection, by its output switching signal.
At present, employed auxiliary contact in the circuit breaker, owing to have problems on the structure, the volume of whole auxiliary contact is increased (46mm * 21mm * 54mm), and also functional reliability is poor.
Task of the present utility model is that a kind of rational in infrastructure, volume is little, functional reliability is good auxiliary contact will be provided.
Task of the present utility model is finished like this, a kind of auxiliary contact, it comprises sensitive switch (4), supporter (2), support (8), sensitive switch (4) is installed on the support (8) by supporter (2), support (8) is fixed on the magnetic conductive board of circuit breaker electric magnetic mechanism, sensitive switch (4) contacts with the moving contact of circuit breaker by its roller (6), and its lead (1) is connected with the control power supply.
The utility model is because after adopting said structure, dwindled volume (43mm * 18m * 31mm), thus the volume of whole circuit breaker is dwindled, improved functional reliability.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is the utility model structure chart.
Fig. 2 is the structure chart of sensitive switch of the present utility model (4).
Earlier with sensitive switch of the present utility model (4), corresponding each other separately positioning screw hole on the support (8) is aimed at, with screw (5) and add the positioning screw hole of packing ring from support (8) and pass, treat that screw (5) passes support (8), add insulating cell (3) again, make screw (5) pass insulating bushing (3) and enter in the positioning screw hole on the sensitive switch (4), screw (5) is twisted then inward, enter opposite side until passing the positioning screw hole on the sensitive switch (4), at this moment add insulating cell (3) again in opposite side, and at its outside stack supporter (2), in the positioning screw hole on the head screw-in supporter (2) of screw (5), sensitive switch (4) is fixed on the support (8) thereby finish.The lead (1) of burn-oning respectively on three utmost points (9) of sensitive switch (4) then, three leads (1) are connected with the control power supply.At last the utility model is passed through the screw (7) on the support (8), be screwed on the magnetic conductive board of circuit breaker electric magnetic mechanism, and the roller (6) of sensitive switch (4) is contacted with the moving contact of circuit breaker.
When circuit breaker is worked,, touch roller (6) on the sensitive switch (4) by moving contact, thereby switching signal is exported along with the closure/disconnection of the moving contact and the fixed contact of circuit breaker.
Claims (1)
1, a kind of auxiliary contact, it is characterized in that it comprises sensitive switch (4), supporter (2), support (8), sensitive switch (4) is installed on the support (8) by supporter (2), support (8) is fixed on the magnetic conductive board of circuit breaker electric magnetic mechanism, sensitive switch (4) contacts with the moving contact of circuit breaker by its roller (6), and its lead (1) is connected with the control power supply.
