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 pin that concatenates 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, some dividing plates are provided with the insulator foot, are kept apart between some series connection static contacts using dividing plate.
Further, the series connection static contact screwed lock is in the outside at the pedestal back side.
Beneficial effect
A kind of breaker series connection fixed contact mounting structure provided by the utility model, directly carries on the back static contact installed in pedestal
The outside in face, prevent the leakage of dynamic/static contact arc discharge from security incident occurs using insulator foot, reduce the difficulty that installation is safeguarded
Degree, on the other hand, by the change of stationary contact head shapes, reduce the cost of parts；And the change of static contact structure makes to flow through
The sense of current of dynamic/static contact is on the contrary, electrodynamic repulsion force between improving dynamic/static contact, so as to improve the interrupting performance of product.
