Detailed Description
The invention will be further illustrated with reference to the following examples:
as shown in the embodiment of fig. 1 and 2, the high-temperature self-power-off electronic connecting piece comprises a shell 1, an electric connecting main piece 2 and an electric connecting auxiliary piece 3 which penetrate through the shell 1, and a connecting piece 5 assembled in the shell 1; the electric connection main sheet 2 and the electric connection auxiliary sheet 3 are respectively disconnected from the left and right sides of the penetrating part of the shell 1, the electric connection sheet 4 is fixed on the shell 1 through a connecting rod 5 made of a memory metal material, the memory metal material of the connecting rod 5 has two states of high temperature and normal temperature, the state of the memory metal material is smaller than the change temperature and is the normal temperature state, the state of the memory metal material is larger than the change temperature and is the high temperature state, the change temperature of the memory metal for selection is 60-100 ℃, and the specific change temperature is selected according to the requirements of an electric appliance. In this embodiment, the connecting rod 5 in the normal temperature state drives the connecting sheet 4 to connect the left and right disconnected main electrical connection sheets 2 as shown in fig. 1; in a high temperature state, as shown in fig. 2, the connecting rod 5 drives the connecting piece 4 to leave the disconnecting position of the electric connecting main piece 2, and the left and right disconnected electric connecting sub pieces 3 are connected.
This high temperature is from outage formula electronic connection piece when using, the main circuit that electric connection main slice 2 inserted electrical apparatus under the normal condition, and the electrical apparatus temperature is in normal atmospheric temperature state, and is less through electric connection main slice 2 and 4 electric currents of even electric slice, and electric connection main slice 2 and even electric slice 4 generate heat seldom for even electric slice 4's temperature is not enough to trigger connecting rod 5 deformation, and is too high when electrical apparatus outside temperature, or when the electric current is too big, even electric slice 4 generate heat and conduct connecting rod 5 with the heat and make connecting rod 5 deformation become the high temperature state, at this moment even electric slice 4 with the 3 switch-ons of electric connection subplate, and the electric connection subplate 3 can connect alarm module or cooling module. This connection piece modular design, direct access circuit, it is convenient to connect, can cut off the power supply to the main circuit when heavy current and outside high temperature simultaneously, can put through the auxiliary circuit simultaneously and carry out the early warning or cool down, and the function is more, uses convenience more.
In specific implementation, when the main electric connection piece 2 is connected to the main electric appliance circuit, the auxiliary electric connection piece 3 is connected to the cooling module. At this time, the current of the cooling module passing through the electric connection sub-plate 3 is smaller than the passing current of the electric connection main plate 2 connected into the electric appliance before the change of the connecting rod 5. This makes it possible to make the contact strip 4 the main power generating element in the case of high currents. Therefore, the connecting sheet 4 can generate heat firstly when the external current is large, and the power-off effect of the connecting sheet is good. In a specific design, a time-delay power-off switch can be connected to the electric connection sub-plate 3. This makes it possible to disconnect the electric connection sub-plate 3 in time after a short operation thereof.
