Disconnected operation is used with conversion, is mainly used for the various places such as industrial, commercial, high-rise and residential premises.
Main component inside miniature circuit breaker is operating mechanism and contact apparatus, by configuring corresponding delay, instantaneously
Mechanism realizes division route, overload, short-circuit protection function.Utilize short circuit current in the touching of dynamic and static contact on breaking technology
Electrodynamic repulsion force is generated at point, to shift to an earlier date arcing before instantaneous mechanism is not operating, reaches limit by the arc resistance that electric arc is formed
The purpose of stream.
In the prior art, when closing operation, handle rotation drives U-shaped bolt and then drives screw-home movement, hasp strap moving contact
System closure.In operation, handle torsional spring torque increases with handle rotation angle, contact system torsional spring torque by
Cumulative big closure in the process.Therefore the closing speed of contact system is still related with manual operation speed, thus influences conjunction
The reliability of lock and the operation lifetime of product.Therefore, breaker needs quick-make function to improve the reliability of product.
Therefore brake component is installed mostly on present handle, for realizing the function of quick-make with support assorted,
However current handle and brake component installation are not easy, and are simply fallen out.
Utility model content
In order to overcome the shortcomings of background technique, the utility model provides a kind of handle mechanism of miniature circuit breaker, main to solve
Handle and the brake component installation of certainly present breaker are not easy, and the problem of simply fall out.
The technical scheme adopted by the utility model is
A kind of handle mechanism of miniature circuit breaker, including handle and brake component, the handle circumferential direction wall are equipped with open slot,
Boss is equipped in the open slot, the brake component is axially arranged with the fixation hole being engaged by clamping with the boss, the open slot
Inner wall is equipped with retention bead, and the brake component is circumferential to be correspondingly provided with escape groove with the retention bead, and the brake component includes stretching
The fashionable retention bead be correspondingly arranged at first position in the escape groove and
When the retention bead is correspondingly arranged above the brake component fixation hole after the installation is completed with the boss
The second position.
There are three the retention bead is set.
The surface of the retention bead is plane.
Blocking arm is additionally provided on the brake component circumferential direction wall, the handle includes side plate, the blocking arm side end face and the side
The side end face of plate is bonded.
The handle includes the shaft for housing hinge, and the shaft upper end forms the boss.
The open slot bottom side is equipped with through slot.
The lower end surface of the side plate is more than the lower end surface of the brake component.
The beneficial effects of the utility model are: the utility model provides a kind of handle mechanism of miniature circuit breaker, the braking
After part is installed in handle, prevent brake component from dropping out by retention bead limit, installation is more firm.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing: as shown, a kind of handle machine of miniature circuit breaker
Structure, including handle 4 and brake component 5, the handle circumferential direction wall are equipped with open slot 41, are equipped with boss 411, institute in the open slot
It states brake component and is axially arranged with the fixation hole 52 being engaged by clamping with the boss, described the inner wall of the open slot is equipped with retention bead 412, institute
It states brake component and is circumferentially correspondingly provided with escape groove 53 with the retention bead, the brake component includes the retention bead pair when protruding into
The first position in the escape groove should be set to and work as the fixation hole and the boss retention bead pair after the installation is completed
The second position above the brake component should be set to.When installation, after brake component is packed into it is lower pressing in place with boss card
It connects cooperation (or clearance fit) to rotate afterwards, so that the upper surface of brake component is located at the lower section of retention bead, prevent brake component from deviating from,
Since the upper end of open slot is equipped with retention bead, diameter opposed open slot lower end is smaller, which can be rectangular
Shape shape rotates the lower section for making its long side fall within the retention bead, to its axial direction after its short side relative limit protrusion is transferred to
Direction is limited, its abjection is prevented.
In the present embodiment, as shown, there are three the retention bead sets.The sky within open slot can rationally be utilized
Between, using effect is more preferably.
