Description

Leakage test button structure of intelligent circuit breaker

Technical Field

The utility model relates to the technical field of circuit breakers, in particular to a leakage test button structure of an intelligent circuit breaker.

Background

According to the demand of intellectualization of a power supply network in China, a plurality of industries require the intellectualization of the power supply network, an electric leakage intelligent circuit breaker device is produced at the right moment, an electric leakage test button in the electric leakage intelligent circuit breaker is welded by a traditional spring piece, the spring piece is easy to deform or break due to the imperfect generation process and welding process of various spring pieces, the service life is greatly shortened, the electric leakage function of a product is frequently lost, electric shock accidents are easy to occur, and the life and property cannot be guaranteed.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides the electric leakage test button structure of the intelligent circuit breaker, which has the advantages of few parts, perfect spring process, no influence from the environment, easy forming of the button, production cost saving and simple assembly.

The utility model solves the technical problems through the following technical scheme:

the utility model provides an electric leakage test button structure of an intelligent circuit breaker, which is characterized by comprising a base, a button, a spring and a control board assembly, wherein the control board assembly is installed in the base, a light touch switch is welded at the top of the side surface of the control board assembly, a button hole and a button limiting surface arranged close to the button hole are formed in the top of the base, a limiting block is fixed at the bottom of the side surface of the button, the button is embedded in the button hole and is in contact limiting with the button limiting surface, the limiting block is positioned in the base, the light touch switch is sleeved with the spring, and the top of the spring is in contact with the contact surface at the bottom of the button.

When the button is pressed by external force, the button can press the spring downwards to enable the spring to generate downward pressure, the bottom contact surface of the button is contacted with and presses the tact switch, the tact switch gives an electric leakage signal to the intelligent circuit breaker, and after the external force for pressing the button disappears, the spring receives self rebound force action to enable the button to recover to the initial free state.

The positive progress effects of the utility model are as follows: the leakage test button structure of the intelligent circuit breaker is simple in structure, few in parts, free of influence of the environment on elasticity of the spring, capable of reducing failure faults of the product button, saving production cost and simple in assembly.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 3, a leakage test button of an intelligent circuit breaker mainly comprises: base 1, button 2, spring 3, control panel subassembly 4 constitute.

As shown in fig. 6, a tact switch 4a is welded to the top side of the control board assembly 4.

As shown in fig. 4, a button hole and a button stopper surface 1a disposed near the button hole are formed at the top of the base 1.

As shown in fig. 5, a stopper 2a and a contact surface 2b that contacts the tact switch 4a are fixed to the bottom of the side surface of the push button 2.

Install control panel assembly 4 in the base 1, the button 2 inlays to be established in the button hole, and stopper 2a contacts spacingly with button spacing face 1a, and stopper 2a is located base 1, dabs and overlaps on the switch 4a and is equipped with spring 3, and the top of spring 3 contacts with contact surface 2b of the bottom of button 2.

As shown in fig. 1, after the product is assembled, the spring 3 in the free state applies an upward pre-pressure F1 to the contact surface 2b of the button 2, so that the limit block 2a of the button 2 contacts with the button limit surface 1a of the base 1, the button 2 is in the pre-compressed state, and the button 2 does not loosen in the free state.

As shown in fig. 2, when the button 2 is pressed by an external force F, the button 2 presses the spring 3 downward, so that the spring 3 has a downward pressure F2, the bottom contact surface 2b of the button 2 finally contacts and presses the tact switch 4a, and the tact switch 4a gives an electric leakage signal to the intelligent circuit breaker. When the external force F for pressing the push button 2 disappears, the spring 3 receives its restoring repulsive force F3, and the push button 2 is restored to the original free state (fig. 1).

While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the utility model, and these changes and modifications are within the scope of the utility model.
