Problems solved by technology

[0003] In the prior art, when assembling the test button, it is impossible to effectively judge whether the button has been assembled in place; the operation of pressing the button may easily cause the button to be deformed or even broken; after the entire assembly is assembled, the position of the button is inconsistent, which is prone to wrong assembly and wrong display problems
Simultaneously, the assembling efficiency of button assembly in the prior art is not high

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] The structure of a button assembly of the present invention is as figure 1 , figure 2 As shown, it includes button 1, spring 2 and housing part 3. A panel 4 is arranged on the shell part 3, and a feature hole is provided between the shell part 3 and the panel 4. The spring 2 presses the button 1 and is installed in the feature hole between the shell part 3 and the panel 4, so that the button 1 can be pressed into a predetermined The upper and lower parts of the feature hole are respectively provided with an upper through hole 13 and a lower through hole 14 that allow the button 1 to pass through and rotate. Make the groove 17 that the bottom of button 1 is embedded.

[0031] The above-mentioned characteristic holes include the upper hole 6 and the lower hole 7 of the housing. The upper hole 6 of the housing is a rectangular columnar hole with arc-shaped protrusio...

Abstract

The invention discloses a button assembly which comprises a button, a spring and a casing part, wherein a panel is arranged on the casing part, a feature hole is formed between the casing part and the panel, the spring presses the button in an against mode and is arranged in the feature hole between the casing part and the panel, a lower through hole allowing the button to penetrate through and rotate is formed in the lower portion of the feature hole, and a groove allowing the bottom of the button to be embedded in is formed in the bottom of the casing part of the lower through hole and corresponding to the position of the feature hole. When the button is assembled and tested, operators only need to perform pressing and rotary operation to judge whether the button is assembled in place. The cross section of the bottom of the button is non-centrosymmetrical section formed by intersecting with a rectangle and a cylinder, therefore, axial mechanical strength of the button can be improved, and deformation or even breakage of the button caused by pressing is avoided. After the whole button assembly is assembled, the position of the button is consistent, the position of a feature identifier on the button is always unchanged, and all the possible wrong assembly and wrong display are avoided. Furthermore, assembly efficiency of the button assembly is increased effectively.

Description

technical field [0001] The invention relates to a test button assembly, which is suitable for a test button of a circuit breaker and an electrical switchgear, especially a circuit breaker. Background technique [0002] The test button on the switchgear is used to test the operation performance of the product. Generally, the button is cylindrical, and the spring preloaded button is in the characteristic hole of the shell to ensure that the button can return to the original state after being pressed into a certain distance. The test button is used for the trigger mechanism of the switchgear. After manually pressing the test button, the operating mechanism of the switch will act to break the switch. [0003] In the prior art, when assembling the test button, it is impossible to effectively judge whether the button has been assembled in place; the operation of pressing the button may easily cause the button to be deformed or even broken; after the entire assembly is assembled, t...
