Abstract
The utility model relates to a self-locking DC breaker, which is characterized in that the self-locking DC breaker comprises a self-locking relay and a switch group. A terminal comprises a permanent power supply end A, a control power supply end B and a ground end D. One end of a relay coil J is connected with the ground end D by a switch K2, the one path of the other end of the relay coil J is connected with the control power supply end B by a control switch K1, and another path of the other end of the relay coil J is connected with the permanent power supply end A by the normally open contact of the relay. A group or a plurality of groups switch contacts J1-2 and J1-3 of the relay J are served as circuit breaking switches. The circuit breaking switches are provided with the switch lead end lines E, F and G. Since the utility model has self-locking function, the self-locking DC breaker of the utility model can simplify the application mode of the relay in the circuit that needs to have the self-locking function, and has simple structure and reliable whole body function.
Description
Technical field:
The utility model relates to electromagnetic switch, a kind of dc circuit breaker of more specifically saying so.
Background technology:
Circuit breaker has a wide range of applications in control circuit.But circuit breaker of the prior art because of himself does not possess auto-lock function, can only be achieved by control circuit is set in addition, thereby increase the complexity of control circuit.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of self-locking dc circuit breaker is provided, and its auto-lock function of providing for oneself can simplified control circuit.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is made up of latching relay and switches set, its terminals comprise standing power end A, control power end B and earth terminal D, the end of relay coil J meets earth terminal D by K switch 2, the other end of relay coil J is leaded up to control switch K1 and is met control power end B, and other has the relay normally open contact of leading up to J1-1 to meet standing power end A; As disconnect, described disconnect has switch leading-out end line E, F, G with one or more groups switch contact J1-2, the J1-3 of relay J.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is because of having auto-lock function, can simplify circuit breaker and possess application mode in the circuit of auto-lock function at needs.It is simple in structure, allomeric function is reliable, can be widely used in automobile, the financial sector, as setting antitheft, anti-snatch function.
Description of drawings:
Accompanying drawing is the utility model circuit theory diagrams.
Embodiment:
Referring to accompanying drawing, in the present embodiment, form by latching relay and switches set, its terminals comprise standing power end A, control power end B and earth terminal D, the end of relay coil J meets earth terminal D by K switch 2, the other end of relay coil J is leaded up to control switch K1 and is met control power end B, and other has the relay normally open contact of leading up to J1-1 to meet standing power end A; As disconnect, disconnect has switch leading-out end line E, F, G with one or more groups switch contact J1-2, the J1-3 of relay J.
In concrete the enforcement, as shown in the figure, in each contact of relay J, between the end pin 4,5 is to be normally opened contact contact J1-2 between normally-closed contact J1-3, the end pin 4,6, is normally opened contact J1-1 between the end pin 1,2, between the end pin 1,3
For fixedly connected between normally-closed contact J1-4, the end pin 2,7.
The self-locking course of work:
The closed condition of maintained switch K2, when connecting control switch K1, at first provide operating current for relay coil J by control power end B, because of relay coil J gets electricly, its normally opened contact J1-1 connects, subsequently, provide the self-locking operating current by standing power end A for relay coil J, enter the self-locking operating state, this state does not change because of opening or closing of control switch K1, realizes self-locking.At this moment, each of switch sections often opened and normally-closed contact turns on and off controlled loop with the state of its setting.When opening K switch 2, locking promptly is disengaged.
In concrete the enforcement, under the locking operating state, standing power end A must keep power supply.
Claims (1)
1, self-locking dc circuit breaker, it is characterized in that forming by latching relay and switches set, its terminals comprise standing power end A, control power end B and earth terminal D, the end of relay coil J meets earth terminal D by K switch 2, the other end of relay coil J is leaded up to control switch K1 and is met control power end B, and other has the relay normally open contact of leading up to J1-1 to meet standing power end A; As disconnect, described disconnect has switch leading-out end line E, F, G with one or more groups switch contact J1-2, the J1-3 of relay J.
