Connection slot regulation-type circuit breaker

Abstract

The invention discloses a connection slot regulation-type circuit breaker, which comprises a circuit breaker body. One end of the circuit breaker body is provided with the connection slot; the connection slot is internally provided with a cable clamping block; the side wall of the connection slot is provided with a regulation cavity; the regulation cavity is internally provided with a regulation pressing plate; a buffer spring is arranged between the regulation pressing plate and the regulation cavity; the circuit breaker body is also internally provided with a through hole; the through hole is internally provided with a through terminal; a pin is arranged on the regulation pressing plate; the pin passes through the buffer spring to extend in the through hole to be connected with the through terminal; the cable clamping block is internally provided with a plug cavity with an opening at the outer side end; the side wall of the cable clamping block is provided with an abutting regulation hole communicating the plug cavity and the outside; the plug cavity is internally provided with a conductive abutting block; and the abutting regulation hole is internally provided with a force pressing column. The connection slot regulation-type circuit breaker has the advantages that the structure is simple; the operation is simple and quick; connection between the circuit breaker and the cable can be effectively and quickly completed; the connection stability is good; and the applicability and the practicality are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a connection slot adjustable circuit breaker. Background technique [0002] With the rapid development of my country's power grid technology, various circuit breakers are used more and more. Circuit breakers are mainly used to cut off and connect the load current of the circuit under normal conditions, and can effectively ensure the normal operation of the circuit when the system fails. To prevent accidents from expanding, it is generally necessary to connect cables when using circuit breakers. At present, cables are connected directly to circuit breakers. Therefore, at least two connection slots are opened on the circuit breaker, and connection holes are provided on the connection terminals of the cables. The cable is inserted into the connection groove through the connection terminal and fixedly connected to the bolt of the circuit breaker through the co...

[0002] With the rapid development of my country's power grid technology, various circuit breakers are used more and more. Circuit breakers are mainly used to cut off and connect the load current of the circuit under normal conditions, and can effectively ensure the normal operation of the circuit when the system fails. To prevent accidents from expanding, it is generally necessary to connect cables when using circuit breakers. At present, cables are connected directly to circuit breakers. Therefore, at least two connection slots are opened on the circuit breaker, and connection holes are provided on the connection terminals of the cables. The cable is inserted into the connection groove through the connection terminal and fixedly connected to the bolt of the circuit breaker through the connection hole. Although it can realize the connection between the cable and the circuit breaker, the connection stability is poor, and in the actual use process, the connection terminal of the cable The width may be greater than the width of the connection groove, so it will also affect the normal connection and use of the circuit breaker and the cable, so the applicability and practicability are limited, and it is difficult to meet the market demand
