In one preferred version: this helical spring 41,42 material selection stainless steel manufactures, to ensure more consistent resiliency characteristics and better mechanical performance, and it is through-flow to make it be not used in, the current path of contact when normal work is made to be: moving contact 20-contact 30-contacts perisporium 15-touch base 13.
In one preferred version: this touch base 13 has an end face, this end face is above-mentioned one practise physiognomy to side, and this end face is arranged with an above-mentioned groove 121 and projection one step 131; This skeleton 14 is in revolving structure and have an annular wall and the projection perisporium 141 in annular wall, and this annular wall is that above-mentioned another is practised physiognomy to side, recessed another the above-mentioned groove 121 of this annular wall, and this perisporium 141 encloses and leans against touch base 13 and outside adaptive step 131; This touch base 13 and skeleton 14 affixed, such as fixed by screw, be formed as above-mentioned mounting groove 12 between this touch base 13 end face and annular wall, helical spring 41,42 contact is between contact 30 and perisporium 141.As required, this touch base 13 can be solid or hollow or open-blind hole.
In one preferred version: this skeleton is made up of metal material, and its outline can form the shielding construction of contact, and structure is more succinct.
Apply a switchgear for described contact apparatus, comprise arc control device, this contact apparatus is installed in arc control device; Separately establish driving mechanism, this driving mechanism connects moving contact 20, moves realization close a floodgate or sub-switching operation to be driven moving contact 20 by driving mechanism relative to fixed contact 10.
Helical spring 42 provides the contact between the contact perisporium of contact 30 and touch base, and when switch closes a floodgate, due to the insertion of moving contact 20, helical spring 41 is subject to radial compression and produces inclination and distortion, provides the contact between contact 30 and moving contact 20.
