Back-moving spring 45, iron core 43 are fixed with laser welding or the mode of screw thread with connecting rod 44.This mechanism release conditions such as Fig. 1,
After relay pushing mechanism start-up operation adhesive such as Fig. 3, dynamic tactile bridge 2 and the contact of fuse stationary contact, load pass through insurance
Silk, when load current is too high or circuit occurs short-circuit, the external blowout magnet of relay, cooled hydrogen in cavity and
In the presence of the triple arc extinguishings of quartz sand of ceramic intracavitary, can rapid arc extinguishing, effectively increase life of product.Two groups of insurance stationary contacts
Point acts on simultaneously, and safer plays a protective role.The ceramic vertical barricade in chamber surface can increase movable contact and touch climbing for bridge with dynamic
Electrical distance, copper scale conducting movable contact and dynamic tactile bridge during the actuating of relay are prevented, relay still turns on after blown fuse..
Under attracting state, upper insulating boot 461 isolates connecting rod 44 with high-voltage load end with lower insulating boot 462, and then by high-low pressure
Insulation, avoids the damage of low-pressure end component and the generation of punch-through, so as to improve the quality of product and security.
The present invention carries out overload protection using fuse, effectively avoid that load current is too high or short circuit caused by it is dangerous.
The external blowout magnet of relay simultaneously, in the presence of the triple arc extinguishings of quartz sand in cooled hydrogen and ceramic ring in cavity,
Can rapid arc extinguishing, effectively increase life of product.The dynamic tactile bridge of two groups of fuses acts on simultaneously, and then improves the fusing of product
Accuracy and the security that uses.Comparatively speaking, fuse is combined by the present invention with relay, and having saved entirety makes
With space and cost, the arc-extinguishing mechanism of relay is used to the quality and security that product can be effectively lifted on fuse.
The present invention carries out overload protection using fuse, if the safeguard measure of other forms is also in the range of this patent；This
It is ceramic material to invent the dead ring used, if other nonmetallic materials can equally fix movable contact also originally special
