Description
Technical Field
The utility model relates to a circuit breaker, concretely relates to but circuit breaker circuit board wiring mechanism of positive and negative wiring.
Background
The circuit breaker is used for being connected into a circuit, detecting the conditions of short circuit, leakage, overload and the like of the circuit and timely breaking the circuit to ensure the power utilization safety. The circuit board is an important component of the circuit breaker and is used for receiving signals and feeding back to control the coil to be electrified so as to realize the disconnection of the circuit breaker; traditional circuit breaker, its circuit board generally links together with the leading-out terminal, when the circuit breaker is closed, the leading-out terminal can be circular telegram, and then guarantee the normal work of circuit board for the circuit board power supply, when the circuit breaker breaks off because of reasons such as broken circuit or overload, the leading-out terminal outage, the circuit board also can break off the power supply and then guarantee that the circuit board can not burnt out, but in the in-service use process, also can take place the user with the condition of the positive and negative wrong connection of leading-in terminal and leading-out terminal, when reverse wiring, the circuit board is connected with the leading-in terminal in essence, even the circuit breaker disconnection like this, the circuit board still is in the on-state, can lead to the circuit board to burn out, influence the subsequent normal use of circuit breaker.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design can effectively avoid leading to the problem that the circuit board burns out because of user's reverse connection line, promotes the circuit breaker circuit board wiring mechanism of the positive and negative wiring of the stability and the security of its use.
Therefore, the utility model discloses an adopt following scheme to realize:
circuit breaker circuit board connection mechanism of positive and negative wiring includes the handle of being connected with the dropout subassembly, the handle includes the rotation portion, the rotation portion articulates in the casing, the one end of rotation portion is connected with extending portion, its characterized in that: still include the conducting strip, the one end and the yoke electricity of conducting strip are connected, the yoke is connected with the inside static contact electricity of circuit breaker, the one end of conducting strip is provided with the conductive part that can kick-back with extending, is close to the conductive part is provided with the part of connecting electricity, the part of connecting electricity passes through the wire and is connected with the circuit board electricity be provided with the arch on the lateral wall of rotation portion, work as when the handle is pulled to closed position, protruding extrusion conductive part for the conductive part with connect the contact of part of connecting electricity, work as when the handle is pulled to open position, protruding and conductive part separation, the conductive part kick-backs and connects the separation of electric part.
The electric connection piece is a copper pipe.
Above-mentioned technical scheme's circuit breaker circuit board wiring mechanism of positive and negative wiring, simple structure, reasonable in design, the circuit board is not direct to be connected with the inlet wire end or the outlet wire end of circuit breaker, no matter is forward or reverse to connect the electricity, when the circuit breaker closure, the circuit board all can connect the electricity and carry out the power consumption safety inspection, when the circuit breaker disconnection, the circuit board can be together cut off the power supply, avoids the circuit board to be burnt out, and then guarantees the normal use of circuit board, promotes stability and the security of its use.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figure, the utility model discloses a but circuit breaker circuit board wiring mechanism of positive and negative wiring, include the handle of being connected with tripping assembly, the handle includes rotation portion 2, rotation portion 2 articulates in the casing, the one end of rotation portion 2 is connected with pulling portion 1 with extending, still include conducting strip 4, the one end and the yoke 7 electricity of conducting strip 4 are connected, yoke 7 is connected with the inside static contact electricity of circuit breaker, the one end of conducting strip 4 is provided with the conductive part 6 that can kick-back with extending, be close to conductive part 6 and be provided with electrical connection 5, in this embodiment, electrical connection 5 is the copper pipe. The electric component 5 is electrically connected with the circuit board 8 through a conducting wire, the side wall of the rotating part 2 is provided with the bulge 3, when the handle is pulled to the closed position, the bulge 3 presses the conductive part 6, so that the conductive part 6 is in contact with the electric component 5, when the handle is pulled to the open position, the bulge 3 is separated from the conductive part 6, and the conductive part 6 rebounds to be separated from the electric component 5.
The structure of the utility model, when the breaker is closed, the yoke 7 is charged, and at the moment, the protrusion 3 on the handle presses the conductive part 6, so that the conductive part 6 contacts with the electric connection part 5, and then the current is transmitted to the circuit board 8 to realize the electricity connection of the circuit board 8, when the breaker is disconnected, the protrusion 3 on the handle does not press the conductive part 6 any more, the conductive part 6 rebounds and is separated from the electric connection part, at the moment, the electric connection part can be powered off, the power transmission to the circuit board is not continued, the power failure of the circuit board 8 is realized, and the circuit board is prevented from being burnt out, the wiring mode is that the circuit board is not directly connected with the wire inlet end or the wire outlet end of the breaker, no matter the circuit board is positively or reversely powered, when the breaker is closed, the circuit board can be powered on and the electricity utilization safety detection is carried out, when the breaker is disconnected, the circuit board is powered off together, the circuit board is prevented from being burnt out, and the normal use of the circuit board is ensured, the stability and the safety of the use of the utility model are improved.
