In system, the rated operational voltage of low-voltage electrical apparatus is even as high as DC1500V.The method connected using breakpoint, can improve open circuit
The interrupting performance of device.But existing external short circuit row is arranged on outside circuit breaker base, is caused breaker appearance and size to increase, is increased
Installing space etc. is added.
The content of the invention
The purpose of the present invention is to be arranged on for above-mentioned existing external short circuit row outside circuit breaker base, is caused outside breaker
Shape size increases, and increases the technological deficiency of installing space there is provided a kind of breaker series connection fixed contact mounting structure, directly by stationary contact
Head is arranged on the outside at the pedestal back side, prevents the leakage of dynamic/static contact arc discharge from occurring security incident using insulator foot, another
Aspect, by the change of stationary contact head shapes, reduces the cost of parts；And the change of static contact structure makes to flow through dynamic/static contact
The sense of current on the contrary, electrodynamic repulsion force between improving dynamic/static contact, so as to improve the interrupting performance of product.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of breaker series connection fixed contact mounting structure that the present invention is designed, it includes
Pedestal and series connection static contact, it is characterised in that：The series connection static contact is mounted in the outside at the pedestal back side.
Further, the series connection static contact is in the groove outside the pedestal back side, outside the insulator foot closure base back side
The groove in portion.
Some concatenation pin are stretched out on the series connection static contact, each concatenation pin is provided with a stationary contact, the stationary contact
Stretch into corresponding with moving contact in the via of pedestal back side groove.
The stationary contact it is identical with the corresponding moving contact sense of current or on the contrary, and series connection static contact on adjacent stationary contact
The sense of current it is identical or opposite.
Compression leg is stretched out in the insulator foot, compression leg props up stationary contact.
Further, it is provided between some dividing plates, some series connection static contacts and is kept apart using dividing plate in the insulator foot.
Further, outside of the concatenation static contact screwed lock at the pedestal back side.
Beneficial effect
A kind of breaker series connection fixed contact mounting structure that the present invention is provided, is directly arranged on the pedestal back side by static contact
Outside, prevents the leakage of dynamic/static contact arc discharge from occurring security incident, reduces the difficulty installed and safeguarded, separately using insulator foot
On the one hand, by the change of stationary contact head shapes, the cost of parts is reduced；And the change of static contact structure makes to flow through sound and touched
The sense of current of head is on the contrary, electrodynamic repulsion force between improving dynamic/static contact, so as to improve the interrupting performance of product.
