Molded case circuit breaker final pressure testing mechanism

Abstract

The invention discloses a molded case circuit breaker final pressure testing mechanism. The molded case circuit breaker final pressure testing mechanism comprises a supporting platform, an actuating mechanism arranged above the supporting platform, a connection mechanism arranged on one side of the actuating mechanism, an adjustment mechanism, a buffer mechanism and a clamping mechanism, wherein the adjustment mechanism, the buffer mechanism and the clamping mechanism are arranged on one side of the connection mechanism from top to bottom. A weight sensor is arranged between the buffer mechanism and the clamping mechanism. According to the invention, a mechanical and electrical combination control method and a rigid-flexible mixing combination method are used; the structure appearance is simple and beautiful; false test results caused by man-made reasons are avoided to the greatest extent; the service life of a test part is prolonged; and the accuracy and the reliability of test data are ensured.

Description

technical field [0001] The invention relates to the field of automatic testing of low-voltage molded case circuit breakers, in particular to a final pressure testing mechanism of low-voltage molded case circuit breakers. Background technique [0002] Molded case circuit breaker, also known as molded case switch, is a common protection circuit component. In order to maintain the reliability of the electrical contact of the molded case circuit breaker, prevent false connection or contact bouncing caused by the electric repulsion when encountering an instantaneous short-circuit current, after the molded case switch is manufactured, it is necessary to carry out a final pressure test to ensure Ensure safe and reliable use. [0003] Since the contacts of the customer's products are manually assembled, there will inevitably be precision errors after assembly, resulting in inaccurate test results. In response to this situation, various testing mechanisms have been designed in the i...

[0003] Since the contacts of the customer's products are manually assembled, there will inevitably be precision errors after assembly, resulting in inaccurate test results. In response to this situation, a variety of testing mechanisms have been designed in the industry, but generally the reliability and test rationality are poor, and the appearance is rough. , it is difficult to guarantee the qualification rate of the molded case switch. If things go on like this, it will not only reduce the reputation of the enterprise, but also cause an increase in the production cost of the enterprise
