Border is general all more severe, and relative humidity is larger, and temperature is higher, easily makes the dynamic/static contact of chopper expansion occur and stretches, leads
The loose contact of chopper is caused, so that affecting the normal use of chopper, the impact to damaging property of integrated circuit causes to use
Electricity is unstable, improves maintenance cost.
Therefore it provides a kind of structure of contact terminal of novel breaker, to being carried out by the dynamic/static contact in chopper
Improve and adjust, it is possible to increase the contact strength of chopper, it is to avoid cause contact in contact due to due to environment and vibrations
It is bad, the unstable of electricity system is caused, while reducing impact of the temperature and humidity to chopper dynamic/static contact, expansion is reduced
The impact to gap is shunk, the stability of contact is improved, maintenance is reduced, maintenance cost is reduced, is just become those skilled in the art
The problem of urgent need to resolve.
Utility model content
The purpose of this utility model is to provide a kind of structure of contact terminal of novel breaker, to can be by chopper
Dynamic/static contact is improved and adjusts, it is possible to increase the contact strength of chopper, it is to avoid in contact due to environment and vibrations
Reason causes loose contact, causes the unstable of electricity system, while reducing temperature and humidity to chopper dynamic/static contact
Affect, reduce impact of the dilation to gap, improve the stability of contact, reduce maintenance, reduce maintenance cost.
To solve technical problem described in background technology, this utility model is employed the following technical solutions：
A kind of structure of contact terminal of novel breaker, including chopper, described chopper include moving contact rack and stationary contact
Head fixed plate, also includes static contact and moving contact on described chopper, described moving contact rack is provided with connecting plate, described
Moving contact be connected with the connecting plate on moving contact rack by bolt, described static contact fixed plate is provided with and moving contact phase
Corresponding static contact, described moving contact are set to the column structure that diameter successively decreases step by step, and the connection end of moving contact and connecting plate
The free end with diameter greater than moving contact, described static contact is provided with the connecting hole corresponding with moving contact free end diameter.
Preferably, the surface of the column structure of described moving contact is provided with the detent of bar shaped, the detent told
Being radially arranged parallel to moving contact, the connecting hole on described static contact are provided with the locating piece corresponding with detent,
By the mutual restriction of detent and locating piece on moving contact, be prevented from occur increase vibration when occur moving contact to
The phenomenon of outer abjection, it is possible to increase the contact strength between moving contact and static contact.
Preferably, resistant to elevated temperatures silica gel is evenly coated between described connecting plate and moving contact, silica gel has good leading
Electrical property, can reduce the breakpoint resistance of connecting plate and moving contact junction point to the full extent, what reduction was produced in conduction
Heat, improves the stability of the performance of chopper.
Preferably, described moving contact rack is set to U-shape structure.
Preferably, the inside of the connecting hole of described static contact is provided with for holding out against the shell fragment that holds out against of moving contact, Neng Goutong
Cross and hold out against shell fragment moving contact is held out against, improve the bonding strength of static contact and moving contact, prevent from going out in vibration and contraction
The phenomenon of existing loose contact, improves the stability of circuit.
The beneficial effects of the utility model are：
1) contact strength of chopper can, be improved, it is to avoid cause contact in contact due to due to environment and vibrations
It is bad, cause the unstable of electricity system.
2) impact of the temperature and humidity to chopper dynamic/static contact, is reduced, impact of the dilation to gap is reduced, is carried
The stability of high contact, reduces maintenance, reduces maintenance cost.
