Description
Technical field
The invention belongs to Low Voltage Electrical Apparatus, in particular to a kind of handle mechanism of miniature circuit breaker.
Background technique
Miniature circuit breaker has the characteristics of advanced structure, reliable performance, strong breaking capacity and small size, main to use
In exchange 50HZ or 60HZ, voltage rating 400V hereinafter, rated operational current is the place below 125A.Make office building, house
The overload and short-circuit protection of illumination, distribution line and equipment with similar building are used, and be can also be used as route and are infrequently led to
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.
Summary of the invention
In order to overcome the shortcomings of that background technique, the present invention provide a kind of handle mechanism of miniature circuit breaker, mainly solve existing
Breaker handle and brake component installation be not easy, and the problem of simply fall out.
The technical scheme adopted by the invention is that:
A kind of handle mechanism of miniature circuit breaker, including handle and brake component, the handle circumferential direction wall is equipped with open slot, described
Boss is equipped in open slot, the brake component is axially arranged with the fixation hole being engaged by clamping with the boss, described the inner wall of the open slot
Equipped with retention bead, the brake component is circumferential to be correspondingly provided with escape groove with the retention bead, and the brake component includes when protruding into
The retention bead be correspondingly arranged at first position in the escape groove and
When the fixation hole and the boss after the installation is completed the retention bead be correspondingly arranged above the brake component 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 present invention are: the present invention provides a kind of handle mechanism of miniature circuit breaker, which is installed to
After in handle, prevent brake component from dropping out by retention bead limit, installation is more firm.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings: as shown, a kind of handle mechanism of miniature circuit breaker, packet
Handle 4 and brake component 5 are included, the handle circumferential direction wall is equipped with open slot 41, is equipped with boss 411, the system in the open slot
Moving part is axially arranged with the fixation hole 52 being engaged by clamping with the boss, and described the inner wall of the open slot is equipped with retention bead 412, the system
Moving part is circumferential to be correspondingly provided with escape groove 53 with the retention bead, and the brake component, which includes that the retention bead is corresponding when protruding into, to be set
In the first position in the escape groove and when the retention bead is corresponding after the installation is completed sets for the fixation hole and the boss
The second position above the brake component.When installation, match in place with boss clamping after brake component is packed into lower pressing
It closes (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, due to
The upper end of open slot is equipped with retention bead, therefore its diameter opposed open slot lower end is smaller, which can be rectangle 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
It is limited, prevents its abjection.
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.
