Description
Technical Field
The utility model relates to a circuit breaker, concretely relates to test button mechanism of circuit breaker.
Background
The breaker is used for being connected into a circuit, detecting the conditions of short circuit, leakage, overload and the like of the circuit and timely breaking the circuit to ensure the power utilization safety. The test button mechanism is an important component of the circuit breaker and is mainly used for testing whether the circuit breaker can normally perform electric leakage detection. The traditional test button mechanism is quite complex in structure and often needs to occupy a large installation space.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a structure is compacter is provided, has and reduces its required installation space for its equipment is simpler, and makes things convenient for the test button mechanism of the circuit breaker of laying of other parts.
Therefore, the utility model discloses an adopt following scheme to realize:
test button mechanism of circuit breaker, including the shell seat, its characterized in that: the testing device comprises a shell seat and is characterized in that a base is arranged on the side portion of the top end of the shell seat, a testing button is slidably arranged in the base, a step is arranged at the bottom of the base, a spring is arranged between the step and the testing button in a pressing mode, the spring is electrically connected with a lead, the lead bypasses a zero line mutual inductor, an electric connection portion is connected to the spring and is located above a magnetic yoke, the magnetic yoke is electrically connected with a static contact, and when the testing button is pressed down, the electric connection portion is electrically connected with the magnetic yoke in a contact mode.
The electric connection part comprises a straight rod section, a contact section is arranged at the bottom of the straight rod section in a bending mode, and the contact section can be in contact with the magnetic yoke.
The base and the shell seat are an integrated forming mechanism.
Above-mentioned technical scheme's test button mechanism of circuit breaker, simple structure, reasonable in design sets up the base through the lateral part on the top of shell seat to set up test button in the base, make test button's overall structure compacter, effectively reduced its required space of installation, make things convenient for laying of other parts inside the circuit breaker.
Drawings
The utility model discloses there is following figure:
fig. 1 is a structural diagram of the present invention disposed in a circuit breaker;
FIG. 2 is an enlarged view of a portion of FIG. 1 at the point A;
fig. 3 is a structural diagram of the present invention with the base removed.
Detailed Description
As shown in the figure, the utility model discloses a test button mechanism of circuit breaker, including shell seat 8, be provided with base 3 at the lateral part on shell seat 8 top, base 3 makes things convenient for its production and processing with shell seat 8 is integrated into one piece mechanism. A test button 1 is arranged in a base 3 in a sliding mode, a step 9 is arranged at the bottom of the base 3, a spring 2 is arranged between the step 9 and the test button 1 in a pressing mode, the spring 2 is electrically connected with a wire 4, the wire 4 bypasses a zero line mutual inductor, a power connection part is connected onto the spring 2 and located above a magnetic yoke 5, the magnetic yoke 5 is electrically connected with a static contact, and when the test button 1 is pressed down, the power connection part is electrically connected with the magnetic yoke. Specifically, the power connection part comprises a straight rod section 6, a contact section 7 is arranged at the bottom of the straight rod section 6 in a bending mode, and the contact section 7 can be in contact with the magnetic yoke 5.
The utility model discloses a this kind of structure sets up base 3 through the lateral part on the top of shell seat 8 to set up test button 1 in base 3, make test button 1's overall structure compacter, effectively reduced its required space of installation, make things convenient for laying of inside other parts of circuit breaker. When the test is needed, the test button 1 can be pressed down to extrude the spring 2, the electric connection part descends, the contact section 7 of the electric connection part is in contact with the magnetic yoke 5 to conduct electricity, the current can flow through the electric connection part, the spring 2 and the wire 4, the wire 4 bypasses the zero sequence transformer, the zero sequence transformer detects an electric leakage signal and feeds the electric leakage signal back to the circuit board to control the disconnection of the circuit breaker and simulate the electric leakage condition, and the normal use of the electric leakage detection function of the circuit breaker is tested.
