Description
Technical field
This utility model relates to Low Voltage Electrical Apparatus, particularly relates to a kind of mold cased circuit breaker.
Background technology
Breaker of plastic casing is in low-voltage electrical field as main disjunction circuit arrangement, and its application is extremely wide.Existing skill
In art, mold cased circuit breaker is the most all via staff's driving handle, and then the linkage of band pneumatic operating mechanism, operating mechanism band
Dynamic moving contact and the static contact realization deciliter being installed on pedestal, in actually used, the action radian of handle is excessive, and then
Make the dynamic and static contact impulsive force when contact too big, easily damage contact, especially, when moving contact and static contact close,
The action radian coordinating upper handle is excessive, it is easy to the static contact that makes bend, and then make static contact be in fatigue state for a long time,
In the course of time, the position of static contact is easily deformed, and further results in the incomplete contact between of moving contact and static contact, great shadow
Ring the service life of breaker of plastic casing.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of simple in construction, modern design, use
Reliably, stable mold cased circuit breaker.
For achieving the above object, this utility model relates to a kind of mold cased circuit breaker, including pedestal, upper cover and handle and
The operating mechanism that is arranged in pedestal, contact system, tripping mechanism, arc-chutes, described handle links with described operating mechanism, institute
State handle and there is curved portions and the centre position from described curved portions is perpendicular to the push rod portion that this curved portions extends, described curved portions
Lower section offers the bayonet socket for being connected with described operating mechanism, and the left and right sides in described push rod portion has horizontal expansion slide bar
Portion, described on cover and offer the window passed for the push rod portion of described handle, the left and right sides of described window has longitudinal direction
Upwardly extending boss, the medial surface of described boss offers the arc-shaped limit groove adaptive with described slide bar portion, described arc
The two ends of stopper slot form positive stop end, are provided with soft cushion in described positive stop end, in this utility model, and described soft buffering
Layer can use the materials such as rubber elastic layer or soft cotton.For preventing staff from skidding when driving handle, this practicality is new
Type specially before and after described push rod portion, be provided with skid resistant course on two sides, this skid resistant course can use soft rubber directly with viscous
The mode of patch is arranged on before and after push rod portion two sides or directly before and after push rod portion, the disposable pressing mold in two sides molds
The mode of " V " type groove realizes anti-skidding.
By the above-mentioned improvement to prior art, mold cased circuit breaker of the present utility model has following remarkable result: by
In being provided with the arc-shaped limit groove adaptive with described slide bar portion, when handle is promoted by staff, in institute upper covering
The positive stop end stating arc-shaped limit groove stops, so the radian that prevents handle to promote excessive and time dynamic and static contact is touched
Impulsive force is too big, and also reduces the factor of static contact deformation, it is ensured that reliability during dynamic and static contact, improves
The service life of mold cased circuit breaker of the present utility model.

Detailed description of the invention
As Figure 1-5, the present embodiment relates to a kind of mold cased circuit breaker, including pedestal 1, upper cover 2 and handle 3 and set
Put the operating mechanism 4 in pedestal, contact system 5, tripping mechanism 6, arc-chutes 7, described handle 3 and described operating mechanism 4
Dynamic, understand in conjunction with Fig. 4 and Fig. 5, in the present embodiment, described handle 3 has curved portions 30 and the centre from described curved portions 30
Position be perpendicular to this curved portions 30 extend push rod portion 31, offer below described curved portions 30 for described operating mechanism 4
The bayonet socket 300 connected, the left and right sides in described push rod portion 31 has horizontal expansion slide bar portion 310, further combined with Fig. 1 and Fig. 2
And Fig. 3 understands, in the present embodiment, described upper cover 2 offers the window passed for the push rod portion 30 of described handle 3
20, the left and right sides of described window 20 has the boss 21 extended longitudinally upward, the medial surface of described boss 21 offers with
The arc-shaped limit groove 210 of described slide bar portion 310 adaptation, the two ends of described arc-shaped limit groove 210 form positive stop end 2100, in this reality
Execute in example, be provided with soft cushion (being identified in the present embodiment) in described positive stop end 2100, it is clear that art technology
Personnel are by reasoning out of combining that technique scheme can be obvious, and the soft cushion described in the present embodiment can use rubber bullet
The property material such as layer or soft cotton, same, in the present embodiment, for preventing staff from skidding when driving handle 3, this reality
Execute example specially before and after described push rod portion 31, on two sides, be provided with skid resistant course (being identified in accompanying drawing), this skid resistant course
Soft rubber can be used directly to be arranged on before and after push rod portion 31 two sides in the way of stickup or directly in push rod portion 31
Front and back the disposable pressing mold in two sides molds the mode of " V " type groove and realizes anti-skidding.
This utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
