Problems solved by technology

However, when the internal and external circuits are to be disconnected, the main body of the terminal needs to be pulled outward to drive the terminal connecting block out of the internal circuit. During the process of moving the terminal connecting block outward, there is a large friction force between the terminal connecting block and the frame body. The connection between the main body and the terminal connection block is unstable or even separated during the pulling process, so that when the terminal body is inserted into the terminal connection block for the second time, the terminal connection block must be manually pulled to the port of the frame body, which is practical and inconvenient, and will cause external The circuit and the transition circuit are in poor contact or even disconnected

Embodiment Construction

[0018] A preferred embodiment of a circuit breaker plug-in terminal of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0019] Such as figure 1 and image 3 As shown, the circuit breaker plug-in terminal, the main body includes three parts: the frame body 1, the terminal connection block 2 and the terminal body 3. The frame body 1 is a frame structure with openings at both ends. There is a rectangular cavity inside the frame. A pair of inner walls are provided with parallel guide rails 11, and the terminal connection block 2 can move in the cavity of the frame body 1 along the guide rails 11; the terminal connection block 2 is generally in the shape of a cuboid adapted to the cavity of the frame body 1. The two ends are located in the guide rail 11, and there are two rows of several electrical connecting parts inside to form a transition circuit. There are two rows of square holes on the upper and lower end faces, and ea...

Abstract

The invention relates to a component of a universal circuit breaker, in particular to a circuit breaker plug-in connecting terminal. The circuit breaker plug-in connecting terminal comprises a frame body, a terminal connecting block and a terminal body, wherein the frame body is of a framework structure with openings on both ends, and the inner wall of the framework is provided with a guide rail; the terminal connecting block can move in the frame body along the guide rail; groups of electrical connecting components are installed in the terminal body and the terminal connecting block which are matched in mutual plug-in manner, the electrical connecting components in the terminal body and the terminal connecting block are communicated when the terminal body is plugged in the terminal connecting block, and the terminal connecting block selectively connects or disconnects a main circuit as the terminal body pushes the terminal connecting block to plug in or draw out of the frame body; and a push-and-pull force transmission device for maintaining the synchronous movement of the terminal connecting block and the terminal body is also arranged on the terminal connecting block and the terminal body. Because the push-and-pull force transmission device is added, the plug-in and the pull-out of the terminal connecting block has an independent point of strength, and the stable contact between the terminal connecting block and the terminal body is ensured.

Description

technical field [0001] The invention relates to components of a universal circuit breaker, in particular to a circuit breaker plug-in terminal. Background technique [0002] The circuit breaker is used to connect internal circuits and external circuits within a certain range, and its function is equivalent to a main switch. According to the connection mode, the wiring terminals of the circuit breaker can be divided into front-panel wiring, rear-panel wiring and plug-in terminal. The circuit breaker using the plug-in terminal omits the necessary isolator in the wiring terminal of the original general circuit breaker, improving It not only improves the economy of use, but also increases the safety and reliability of operation and maintenance. [0003] The plug-in terminal mainly includes three parts: the terminal body, the terminal connection block and the frame body. The terminal body is connected to the external circuit, and the transition circuit is set inside the terminal...
