Between be reserved with explosion-proof cell, the shell inner cavity wall in the middle part of explosion-proof cell is inwardly protruding to form explosion-proof snap ring, is installed in explosion-proof snap ring
Partition, separator edge are recessed capel, and capel is chimeric with explosion-proof snap ring, are reserved between the partition bottom and core after being fitted into
Surge chamber is marked with electrolyte in surge chamber, forms partition room at the top of partition between cap base, and partition is indoor to be equipped with partition group
Part.
Described lead one end is connect with core, and the other end passes through partition and connect with pole foot, is solid between lead and partition
Fixed connection is greater than partition to the length between core positioned at indoor wire length is buffered.
The partition assembly includes fixed articulation block, driving lever, jacking block, wherein and fixed articulation block is fixed on cap base, Gu
Determine to be hinged with driving lever on articulation block, be hinged on fixed articulation block in the middle part of driving lever, driving lever one end is connect with indoor lead is separated, driving lever
The other end is hanging, and the jacking block of protrusion is equipped at the top of the partition below free end.
The top cover is made of rigid rubber material.
The present invention is after adopting the above scheme, when the pressure in shell becomes larger, pressure extrusion partition, separator edge it is embedding
Ring can gradually deviate from explosion-proof snap ring, break the indoor lead of buffering when deviating from a spacing Gao Shihui, at the same increase in pressure and
During capel is deviate from, jacking block gradually squeezes the free end of driving lever upwards, pulls lead by driving lever, will under pressure effect
Separate indoor lead to break, capacitance leading wire is broken to realize, realizes explosion-proof purpose.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Fig. 2 is enlarged diagram at the A of Fig. 1.
Specific embodiment
Below with reference to all attached drawings, the invention will be further described, presently preferred embodiments of the present invention are as follows: referring to 1 He of attached drawing
