An overheat-proof remote monitoring switch device

Abstract

The utility model discloses an overheating-proof remote monitoring switch device, which relates to the technical field of switch devices, and comprises a switch box and a terminal block arranged at one end of the switch box. When an external wire is connected, heat at a connection end is conducted through a heat-conducting pressure plate and a heat-conducting card plate. The heat-conducting card plate and a small heat-conducting plate form a split assembly structure, which will not hinder the normal connection of the wire. The heat-conducting pressure plate, the heat-conducting card plate, and a small heat-conducting plate, a heat-conducting fin plate and a reinforcing fin plate that are clamped together with the heat-conducting card plate form a large heat dissipation area, which can efficiently absorb the heat generated at the connection end and exchange heat with air to further increase the heat dissipation area. The first heat dissipation grooves and ventilation holes provided on the heat-conducting fin plate and the reinforcing fin plate increase the contact area with the air, which can effectively improve the heat dissipation rate. The reinforcing fin plate is wavy, which can support the heat-conducting fin plate while also maximizing its heat dissipation area.
