Description

A plug-in miniature circuit breaker housing installation structure

technical field

The invention belongs to the technical field of circuit breaker equipment, and in particular relates to a plug-in small circuit breaker housing installation structure, which can meet the needs of DC current input and output from the inside and outside of the circuit breaker installation panel.

Background technique

Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to a fuse switch and The combination of overheating and underheating relays, etc., and generally does not need to change parts after breaking the fault current, has been widely used.

The use of circuit breakers can effectively improve the safety of the electrical equipment industry. With the widespread use of circuit breakers on various electrical equipment, in order to meet the installation needs of various electrical equipment, the structure of circuit breakers has also developed to various types. Similarly, in the layout of the installation position of the existing traditional circuit breaker products, the operating device is on the left side of the panel of the operation and installation cabinet, while the input port and output port of the low-voltage circuit breaker and the circuit breaker body, the installation and fixing buckle position of the circuit breaker are in the operation Install the right side of the cabinet panel, but with the development of electrical equipment technology for circuit breaker matching, in some special occasions, especially when the installation space of the circuit breaker is relatively small, the output/input port end of the connecting wire needs to be installed on the panel of the cabinet. Outside, one end is in the installation cabinet, and the overall direction is perpendicular to the panel. If the wiring is still done in the traditional way, it is necessary to add external connecting wires and copper bars, which takes up a lot of space and high switching costs.

Contents of the invention

One end of the output/input port of the connecting wire needs to be outside the panel of the installation cabinet, and the other end is inside the installation cabinet, and the overall direction is perpendicular to the panel. Adding external connecting wires and copper bars takes up a lot of space and high switching costs. Redesign a plug-in miniature circuit breaker shell installation structure, through the plug-in custom interface, the circuit where the circuit breaker is located is the shortest current path in the entire low-voltage transmission and distribution conductive system, saving installation and wiring space, thereby saving materials , resulting in good economic benefits.

Further, an indication hole is provided on the upper surface of the button, and an indicator is connected to the button, and the indicator displays the closing and opening state of the circuit breaker through the indicating hole.

Further, both the left terminal 1 and the left terminal 2 are provided with a connection port and an operation port;

Further, the opening directions of the connection port and the operation port are parallel to the movement direction of the button.

Further, the buckle is integrally made with the shell body or is snap-fitted on the shell body.

Further, the first right junction slot, the information line junction slot and the second right junction slot are plug-in type junction slots. Beneficial effect

A plug-in small circuit breaker housing installation structure designed by the present invention, through the plug-in custom interface, makes the circuit where the circuit breaker is located in the entire low-voltage transmission and distribution conductive system the shortest current path, saving installation and wiring space, thereby Save materials and produce good economic benefits.
