Description
Technical field
The utility model relates to the component parts of universal circuit breaker, is specifically related to a kind of plug-in connecting terminal that uses in omnipotent breaker.
Background technology
Circuit breaker is used for connecting the internal circuit and the external circuit of certain limit, its effect is equivalent to master switch, circuit breaker basic structure comprise two parts, i.e. binding post and drive unit, under the drive of drive unit, binding post can be communicated with or open circuit.The binding post of circuit breaker is according to different connected modes, can be divided into wiring and plug-in connecting terminal behind wiring before the plate, the plate, adopt the circuit breaker of plug-in connecting terminal, omitted the interior necessary isolator of binding post of original general circuit breaker, improved the economy of using, bring very big convenience to operation and maintenance simultaneously, increased fail safe, reliability.
Owing to the circuit breaker that adopts plug-in connecting terminal has above-mentioned advantage, therefore all comparatively convenient in operation, maintenance and replacement, obtained using comparatively widely at present so have the circuit breaker of plug-in connecting terminal.
The circuit breaker that has plug-in connecting terminal, its structure generally are divided into body and plug-in connecting terminal two parts of circuit breaker, wherein, are provided with drive unit in the body of circuit breaker, drive unit in order to the motion that drives plug-in connecting terminal to realize its function; The plug-in connecting terminal part then is divided into the housing underframe that fixes and the terminal bodies two parts that can relatively move with circuit breaker in underframe, constitute the chamber of both ends open in the underframe, be provided with guide rail in the chamber, the outer end of guide rail is provided with a stopping means, also be provided with the terminal contiguous block that can on the guide rail in the support body of underframe, slide in the underframe, when the terminal contiguous block slid into the guide rail end, main circuit inserted the terminal contiguous block; And circuit on the binding post main body and external circuit also are that secondary circuit links to each other.Therefore, in order to connect main circuit and secondary circuit, the general circuit breaker that has plug-in connecting terminal all comprises moving binding post and quiet binding post, and moving binding post is installed on the terminal bodies of binding post; Quiet binding post is installed on the terminal contiguous block of underframe, by the connection of finishing whole major-minor circuit that is connected of moving binding post and quiet binding post.
The operating state of circuit breaker is divided into three kinds, that is: " connection " state, centre " test " state and " disconnected position " state.In " connection " state, the major and minor circuit of circuit breaker all connects; At " test " state, main circuit separates and secondary circuit connects, and in " disconnected " state, major and minor circuit all separates.The circuit breaker that has plug-in connecting terminal is realized above-mentioned three kinds of operating states according to following principle: the drive unit drive terminal main body of circuit breaker is inserted the terminal contiguous block that is positioned at underframe, the quiet binding post that is positioned at the moving binding post on the terminal bodies this moment and is positioned on the terminal contiguous block joins, the secondary circuit of conducting, at this moment, since the terminal contiguous block do not move to the guide rail end as yet, so the main circuit access failure, this is a trystate; Terminal bodies continues to move forward, and promotes the terminal contiguous block to the guide rail end, and the moving binding post on the terminal bodies keeps being communicated with the quiet binding post of terminal contiguous block at this moment; Circuit on the terminal contiguous block is communicated with main circuit, thereby realizes that the major-minor circuit all connects, and this is a connection status; The drive unit of circuit breaker oppositely spurs terminal bodies when needs cut off the power supply, and drive terminal contiguous block counter motion, the terminal contiguous block is at first thrown off with main circuit, main circuit short circuit this moment, secondary circuit keeps conducting, recover the trystate of circuit breaker, terminal bodies continues to move under the drive unit effect, further pulling terminal contiguous block moves in guide rail, after stopping means that the terminal contiguous block is positioned at the guide rail end blocks, terminal bodies and terminal contiguous block are thrown off, thereby disconnect the major-minor circuit, and this is the disconnected position state of circuit breaker.
Because there are resistance in moving binding post on the terminal bodies and the quiet binding post on the terminal contiguous block in the process of inserting, what be easy to expect is, when drive unit drive terminal main body moves forward, will inevitably cause the terminal contiguous block also to produce proal trend, this trend will cause between quiet, moving binding post on terminal contiguous block and the terminal bodies can't firm plug, and then the secondary circuit contacts that causes being in the circuit breaker under " test " state is bad, thereby may cause the output signal instability of secondary circuit.For addressing this problem, EUROPEAN PATENT OFFICE discloses the artificial Schneider Electric Devices of application, the patent No. is FR2796768A1, name is called the patent of invention of " Auxiliary electrical connector for a plug-in electrical low or high voltagepower switch.has connectors with associated slider and guide ", as shown in Figure 1, this patent has been described a kind of connecting terminal apparatus of circuit breaker, comprise support body 100, terminal bodies 200 and terminal contiguous block 101, support body 100 is fixed on the circuit breaker by screw 104, the binding post of this structure is by evenly being provided with the cylinder 102 of some projectioies on the terminal contiguous block 101 in support body 100, in support body 100, be provided with two ends and solve this problem with the mode of the extension spring 103 of support body and cylinder 102 Joints respectively, extension spring 103 is corresponding with the quantity and the position of described cylinder 102, when terminal bodies 200 promotion terminal contiguous blocks 102 move forward, extension spring 103 is extended gradually, and give the terminal contiguous block 101 1 pulling force opposite with its direction of motion, can guarantee elongation gradually like this along with extension spring 103, the effect of pulling force also will strengthen, make and lay respectively at moving on terminal bodies 200 and the terminal contiguous block 102, quiet binding post connects all the time comparatively closely, has guaranteed the stable of secondary circuit output signal.
