Abstract
The utility model discloses large opening high-breaking miniature breakers, including the handle and transmission mechanism being arranged in housing, handle is rotated along the first rotation axis, transmission mechanism includes lock, tripping, contact base and moving contact, lock and contact base are rotated along the second rotation axis, the upper right quarter of tripping one end and contact base is hinged, the other end is clamped with lock, handle is connect by connecting rod with tripping, moving contact is arranged on contact base, the horizontal distance in the axle center of the first rotation axis and the axle center of the second rotation axis is 12.2 millimeters, vertical range is 8.7 millimeters, when energy accumulation handle is in open position, the axle center of first rotation axis is 15.2 millimeters with the horizontal distance of tripping and the hinged central point of contact base, vertical range is 1.6 millimeters.Using above-mentioned technical proposal, moving contact increases to 7.5~8.5 millimeters away from distance with opening after static contact disconnection from original 5 millimeters so that breaker can bear the breaking current of bigger, while can guarantee the stability of breaker actuation again.
Description
Technical field
The utility model is related to miniature circuit breaker fields, and in particular to a kind of large opening high-breaking miniature breaker.
Background technology
Miniature circuit breaker can be both used as the overload and short-circuit protection of electrical equipment of low voltage, can also be used as circuit not
Frequent on-off line operation is used with conversion.When excessive by the electric current of breaker, breaker can disconnect ensureing that electricity consumption is pacified automatically
Entirely, very big electric arc and very high heat can be generated between moving contact and static contact when breaker disconnects, with reference at present on the market
Breaker, moving contact and static contact disconnect after open away from distance general only 5 millimeters or so, when by electric current be more than
After 8000 peaces, burning for moving contact and static contact is easily caused, since the relevance of miniature circuit breaker inner structure size is very big,
In order to increase opening away from distance after moving contact is disconnected with static contact, need to redesign the ruler of handle and transmission mechanism on the whole
Very little and structure just can guarantee the stability of miniature circuit breaker action.
Invention content
In view of the deficiency of background technology, the technical problem to be solved by the utility model is to provide one kind to increase moving contact
Opening away from distance after being disconnected with static contact so that it can bear the breaking current of bigger without burning, while can guarantee again
The large opening high-breaking miniature breaker of its stability acted.
For this purpose, the utility model is realized using following scheme：
Large opening high-breaking miniature breaker, including the handle and transmission mechanism being arranged in housing, the handle is along
One rotation axis rotates, it is characterised in that：The transmission mechanism includes lock, tripping, contact base and moving contact, described to latch and touch
Headstock is rotated along the second rotation axis, and the upper right quarter of described tripping one end and contact base is hinged, and the other end is clamped with lock, the hand
Handle is connect by connecting rod with tripping, and the moving contact is arranged on contact base, the axle center of first rotation axis with second turn
The horizontal distance in the axle center of moving axis is 12.2~13.6 millimeters, and vertical range is 8.7~10.5 millimeters, when energy accumulation handle is in disconnected
During open position, axle center and the horizontal distance of tripping and the hinged central point of contact base of first rotation axis are 14.6~15.2
Millimeter, vertical range are 1.2~4 millimeters.
Using above-mentioned technical proposal, the advantages of the utility model, is：By redesigning transmission mechanism and determining relevant bits
Put size, after moving contact and static contact disconnect, opening for the two can reach 7.5~8.5 millimeters away from distance, due to moving contact with
Opening after static contact disconnection increases away from distance, when in breaker by the breaking current in 1 Wan An to 1.5 Wan An, will not make
Into burning for breaker, the breaking current that breaker can carry is improved, and ensure that the stability of breaker actuation.
It is preferably opened to obtain away from distance, preferably, the axle center of first rotation axis and the axis of the second rotation axis
The horizontal distance of the heart is 12.2 millimeters, and vertical range is 8.7 millimeters, when energy accumulation handle is in open position, described first turn
The axle center of moving axis is 15.2 millimeters with the horizontal distance of tripping and the hinged central point of contact base, and vertical range is 1.6 millimeters.
Description of the drawings
The utility model has drawings described below：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in the figure, large opening high-breaking miniature breaker disclosed in the utility model, including the hand being arranged in housing

Including lock 6, tripping 5, contact base 8 and moving contact 9, lock 6 and contact base 8 are rotated along the second rotation axis 7, the second rotation axis
7 axis both ends are fixed on housing, and 5 one end of tripping and the upper right quarter of contact base 8 are hinged, the other end and 6 clamping of lock, handle 3
It is connect by connecting rod 2 with tripping 5, moving contact 9 is arranged on contact base 8, the axle center of the first rotation axis 4 and the second rotation axis 7
Axle center horizontal distance L2 for 12.2~13.6 millimeters, vertical range L4 is 8.7~10.5 millimeters, when handle 3 is in Fig. 1 institutes
During the open position shown, the axle center of the first rotation axis 4 and the horizontal distance L1 of tripping 5 and the hinged central point of contact base 8 are
14.6~15.2 millimeters, vertical range L3 is 1.2~4 millimeters.
In order to obtain it is optimal open away from distance, the horizontal distance in the axle center of the axle center of the first rotation axis 4 and the second rotation axis 7
L2 is 12.2 millimeters, and vertical range L4 is 8.7 millimeters, when handle 3 is in open position shown in FIG. 1, the first rotation axis 4
Axle center is 15.2 millimeters with the horizontal distance L1 of tripping 5 and the hinged central point of contact base 8, and vertical range L3 is 1.6 millimeters.It adopts
After above-mentioned technical proposal, when breaker disconnects, opening away from distance L5 up to 8.5 millimeters between moving contact 9 and static contact 1,
The breaking current that breaker bears 1.5 Wan An is allowd to improve the breaking capacity of breaker without burning, ensure simultaneously
Handle 3 and the stability of transmission mechanism action are not in the situation of disengagement.
