[0002] Overcurrent protection is a protection method that makes the protection device operate when the current exceeds the predetermined maximum value. When the current in the circuit increases, the heat generated by the wire will increase, and the current in the circuit will not be reduced in time and heat dissipation , will cause heat accumulation in the circuit, which has a potential safety hazard of fire. When the current is overloaded, not cutting off the circuit in time will not only damage the electrical appliances, but also damage the rubber in the transmission line, making the line lose insulation, which is easy to cause Danger

The invention discloses a parallel circuit overcurrent protection heat dissipation device. The device comprises a device box body, a socket cavity is formed in the device box body, a rotating shaft isrotatably connected to the inner wall of the right side of the socket cavity, a placement cavity with a leftward opening is formed in the rotating shaft, and a sliding threaded rod is connected to the interior of the placement cavity through a spline; and a reset spring is fixedly arranged between the right end face of the sliding threaded rod and the inner wall of the right side of the containing cavity. When the current in the circuit rises, a connecting resistor is connected in parallel in the circuit by utilizing the parallel shunt principle to reduce the current in the circuit, and meanwhile,a power transmission line is timely cooled through blowing fan blades moving left and right to reduce the potential safety hazard; and when the current in the circuit is overloaded, a sliding rack slides downwards at the moment to reduce the potential safety hazard, so that a sliding threaded rod drives a conductive plug to slide rightwards, further a conductive plug is quickly disconnected from a conductive socket, and the circuit and an electric appliance are protected.
Description
Technical field [0001] The present invention relates to the related art of overcurrent protection circuit devices, in particular a parallel circuit overcurrent protection heat dissipation device. Background technique [0002] Overcurrent protection is a protection mode of the protection device to operate when the current exceeds a predetermined maximum, when the current in the circuit becomes larger, the amount of heat generation of the wire becomes large, and the current in the circuit is lowered and heat dissipation. The heat in the circuit will accumulate, with a safety hazard that causes fire. When the current is overloaded, the cut circuit does not turn off the circuit not only damage to the electric appliance, but also causes the rubber lens in the transmission line to lose insulation, easy to cause Danger. [0003] A parallel circuit extends over-through protective heat dissipation means, which can solve the above problems. Inventive content [0004] In order to solve the...
