Abstract
A molded case circuit breaker is disclosed. By using an exciting molded case circuit breaker, a handle influences a response speed of the circuit breaker, the service life is short and installation is difficult. By using the circuit breaker of the utility model, the above problems are mainly solved. The circuit breaker is characterized in that an operation plate (3) is provided with an operating lever (4); a groove (5) which matches with the operating lever (4) is arranged in the handle (2); connection plates (31) are extended from two sides of the operation plate (3); a clamping groove (21) which matches with the connection plates (31) is arranged on the handle (2). By using the mechanism, the structure of a traditional molded case circuit breaker is optimized; installation of the handle and the operating lever is convenient; after the installation is completed, connection is firm; the response speed of the circuit breaker is fast; a built-in flexible component effectively prolongs the service life of the handle.
Description
Technical field
The utility model relates to a kind of circuit breaker, is specifically related to a kind of breaker of plastic casing.
Background technology
Breaker of plastic casing is widely used in the departments such as industrial or agricultural, traffic, mine, civil buildings and national defence, and the protection of the transmission to electric power and distribution, motor cuts much ice, be in low-voltage electrical apparatus use amount large, use wide product.
the handle of existing breaker of plastic casing adopts spring to be connected with operator link or operation panel more, can energy storage, but response speed is slow; Also have employing rigidly connected, but the installation of handle and connecting rod is more loaded down with trivial details, is unfavorable for producing, handle is easy to crack after repeatedly pulling simultaneously.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of breaker of plastic casing, and the handle that has mainly solved existing breaker of plastic casing affects circuit breaker response speed, and useful life is short, and difficult problem is installed.
The technical scheme that the utility model adopts is: a kind of breaker of plastic casing, comprise housing, handle, in described housing, be provided with operation panel, described operation panel is provided with action bars, in described handle, be provided with the groove with action bars adaptation, described operation panel both sides are extended with connecting plate, and described handle is provided with the draw-in groove with connecting plate adaptation.
The coated operation panel of described handle, the upper surface of described operation panel and the inner surface of handle fit, and the inner surface of described handle is provided with screens portion.
Described screens portion includes the first fixture block, the second fixture block of being located at handle inner surface, and described the first fixture block, the second fixture block are positioned at operation panel both sides.
Described the first fixture block, the second fixture block are flexible element.
The beneficial effects of the utility model are: optimized the structure of traditional breaker of plastic casing, handle and action bars are easy for installation, after installation, be connected firmly, and circuit breaker fast response time, built-in flexible element has extended the useful life of handle effectively.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
If Fig. 1 is in conjunction with as shown in Fig. 2 to 4, a kind of breaker of plastic casing, comprise housing 1, handle 2, in described housing 1, be provided with operation panel 3, described operation panel 3 is provided with action bars 4, in described handle 2, be provided with and the groove 5 of action bars 4 adaptations, described operation panel 3 both sides are extended with connecting plate 31, and described handle 2 is provided with the draw-in groove 21 with connecting plate 31 adaptations.
The described coated operation panel 3 of handle 2, the upper surface of described operation panel 3 and the inner surface of handle 2 fit, and the inner surface of described handle 2 is provided with screens portion 6.
Described screens portion 6 includes the first fixture block 7, the second fixture block 8 of being located at handle 2 inner surfaces, and described the first fixture block 7, the second fixture block 8 are positioned at operation panel 3 both sides.
Described the first fixture block 7, the second fixture block 8 are flexible element.
The concrete use of the utility model is as follows: when installation, overlap successively connecting handle 2, operation panel 3, action bars 4 is inserted to groove 5, connecting plate 31 inserts draw-in groove 21; When work, when turning handle 2, handle 2 contacts with operation panel 3 many places, not slippage relatively, fast response time, good stability.
The beneficial effect of utility model is: optimized the structure of traditional breaker of plastic casing, handle and action bars are easy for installation, after installation, be connected firmly, and circuit breaker fast response time, built-in flexible element has extended the useful life of handle effectively.
