[0001] The utility model relates to the technical field of power card board protection devices, in particular to a power card board protection device with a surge suppression function. Background Art

[0002] The power card protection device with surge suppression function is a device used to protect electrical equipment and systems from voltage surge interference on power lines. In electrical systems, lightning strikes, power grid switching, startup of large electrical equipment, etc. may generate instantaneous high voltage in the line, the so-called "surge". The amplitude of this surge voltage is much higher than the rated voltage of the equipment. If it acts directly on the equipment without protection, it may cause equipment damage or even permanent failure. In severe cases, it may cause safety accidents such as fire.

[0003] When the protector is damaged and needs to be replaced, in order to ensure the safety of workers, the power supply must be cut off before replacement can be carried out. However, cutting off the power supply for replacement will affect the normal operation of other electrical equipment. Summary of the invention

[0004] The utility model aims to solve the problems existing in the background technology and proposes a power card protection device with surge suppression function, which can safely replace the protector without cutting off the power supply.

DETAILED DESCRIPTION

[0028] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Example

[0030] like Figure 2-3 and Figure 6As shown, the utility model proposes a power card protection device with surge suppression function, including a main body 1, and also includes an electrical connector 2 detachably mounted on the upper and lower sides of the main body 1, and the electrical connector is electrically connected to an external wire. It also includes a wiring mechanism, and the wiring mechanism fixes the wire to the electrical connector 2. The electrical connector includes a wiring cavity 6 provided on the electrical connector 2, a first copper plate 601 fixedly mounted in the wiring cavity 6, a second copper plate 602 slidably mounted in the wiring cavity 6, a screw rod 603 threadedly connected to the electrical connector 2 and rotatably connected to the second copper plate 602, and a wiring hole 604 provided on the electrical connector 2 and connected to the wiring cavity 6. Insert the wire into the wiring hole 604 so that the wire is located between the first copper plate 601 and the second copper plate 602, and then rotate the screw rod 603 to drive the second copper plate 602 to move in a direction close to the first copper plate 601, so that the second copper plate 602 and the first copper plate 601 squeeze and fix the wire, thereby completing the electrical connection with the wire.

[0031] like Figure 2 As shown, the main body 1 is provided with connection holes 4 at the upper and lower sides, and the electrical connector 2 is provided with a connector 401, and the connection hole 4 is electrically connected to the connector 401. When the connector 401 is inserted into the connection hole 4, the electrical connector 2 and the main body 1 are electrically connected, and the electrical connector 2 and the main body 1 can be connected by bolts, which is convenient for disassembly. When the main body 1 is damaged, only the main body 1 needs to be replaced, and no wiring is required.

[0032] like Figure 3-4 and Figure 7As shown, a circuit breaker mechanism is provided in the electrical connector 2, and the circuit breaker mechanism controls whether the electrical connector 2 can conduct electricity. The circuit breaker mechanism includes an installation chamber 3 provided in the electrical connector 2, a first connection cylinder 301 fixedly installed at the lower side of the installation chamber 3, a first slide column 302 slidably installed in the first connection cylinder 301, a first spring 303 fixedly installed on the first slide column 302 and fixedly connected to the first connection cylinder 301, a first electric sheet 304 fixedly installed on the first slide column 302, a second connection cylinder 305 fixedly installed at the upper side of the installation chamber 3, a second slide column 306 slidably installed in the second connection cylinder 305, a second spring 307 fixedly installed on the second slide column 306 and fixedly connected to the second connection cylinder 305, a second electric sheet 308 fixedly installed on the second slide column 306, a rotating shaft 309 rotatably installed in the installation chamber 3 and located between the first electric sheet 304 and the second electric sheet 308, and a prismatic block 310 fixedly installed on the rotating shaft 309. The four corners of the prism block 310 are provided with rounded corners, and the rounded corners facilitate the prism block 310 to push the first electric sheet 304 and the second electric sheet 308. The first copper plate 601 is electrically connected to the second electric sheet 308, and the first electric sheet 304 is electrically connected to the connector 401. The prism block 310 is a conductive material. When the longer diagonal line of the prism block 310 is in a vertical state, the upper and lower corners of the prism block 310 are in contact with the first electric sheet 304 and the second electric sheet 308 respectively, so that the first electric sheet 304 and the second electric sheet 308 are electrically connected, and then the connector 401 is energized. When the shorter diagonal line of the prism block 310 is in a vertical state, the prism block 310 will not be in contact with the first electric sheet 304 and the second electric sheet 308, and it is in an open circuit state at this time, and the connector 401 is not charged at this time.

[0033] When the main body 1 is replaced, the rotating shaft 309 is first driven to rotate the prismatic block 310 so that the shorter diagonal of the prismatic block 310 is rotated to a vertical state to prevent the worker from touching the connecting head 401 and causing the risk of electric shock. When the replacement is completed, the rotating shaft 309 is rotated to rotate the longer diagonal of the prismatic block 310 to a vertical state. At this time, the connecting head 401 is energized and electrically connected to the main body.

[0034] The elastic force applied by the first spring 303 to the first electric sheet 304 and the elastic force applied by the second spring 307 to the second electric sheet 308 enable the first electric sheet 304 and the second electric sheet 308 to stably contact the prismatic block 310, thereby ensuring the stability of the circuit.

[0035] like Figure 5As shown, it also includes a driving assembly, which drives the rotating shaft 309 to rotate and prevents the rotating shaft 309 from rotating due to accidental touch. The driving assembly includes a connecting plate 5 rotatably mounted on the electrical connector 2, a telescopic rod 501 fixedly mounted on the connecting plate 5, a driving plate 502 rotatably mounted on the telescopic rod 501, and a plurality of third springs 503 fixedly mounted between the driving plate 502 and the connecting plate 5. A plurality of limiting grooves 504 are provided on the connecting plate 5, and a plurality of limiting rods 505 are fixedly mounted on the driving plate 502. The limiting grooves 504 are slidably connected to the limiting rods 505. The rotating shaft 309 can be driven to rotate by rotating the connecting plate 5. When the connecting plate 5 is to be rotated, the driving plate 502 is pressed to move the driving plate 502 in a direction close to the connecting plate 5, so that the limiting rod 505 enters the limiting groove 504. At this time, the rotating driving plate 502 can drive the connecting plate 5 to rotate, and the connecting plate 5 is embedded in the electrical connector 2, and the connecting plate 5 cannot be directly rotated.

[0036] Working principle: insert the wire into the wiring hole 604, then rotate the screw rod 603 to drive the second copper plate 602 to move closer to the first copper plate 601, so that the second copper plate 602 and the first copper plate 601 squeeze and fix the wire, thereby completing the electrical connection with the wire. When the connector 401 is inserted into the connection hole 4, the electrical connector 2 and the main body 1 are electrically connected, and the electrical connector 2 and the main body 1 can be connected by bolts, which is easy to disassemble. When the main body 1 is damaged, only the main body 1 needs to be replaced, and there is no need to reconnect the wires. When the longer diagonal of the prism block 310 is in a vertical state, the upper and lower corners of the prism block 310 are in contact with the first electric sheet 304 and the second electric sheet 308 respectively, so that the first electric sheet 304 and the second electric sheet 308 are electrically connected, and then the connector 401 is energized. When the shorter diagonal of the prism block 310 is in a vertical state, the prism block 310 will not be in contact with the first electric sheet 304 and the second electric sheet 308, and it is in a disconnected state at this time, and the connector 401 is not energized. When the main body 1 is replaced, the rotating shaft 309 is first driven to rotate the prism block 310, so that the shorter diagonal of the prism block 310 is rotated to a vertical state to prevent the worker from touching the connector 401 and causing an electric shock. When the replacement is completed, the rotating shaft 309 is rotated to rotate the longer diagonal of the prism block 310 to a vertical state, and the connector 401 is energized, so as to be electrically connected to the main body.
