Description
Technical field
The utility model relates to a kind of device of technical field of electricity, particularly the movable contact arm of a kind of circuit breaker.
Background technology
The advantage of handcart type high voltage switch cabinet is that its volume is little, working service convenient (pull it when the circuit breaker of a switch cubicle breaks down outside cabinet, the back-up breaker of another same specification is pushed in and can be restored electricity rapidly).How to make handcart by moving in cabinet outside cabinet, the operating process that circuit breaker is advanced into service position by test position is more convenient, reliable, the operating personnel that are more convenient for carry out various control operation to circuit breaker, are the research directions of each switch cubicle producer at present, at home and abroad also have a wide range of applications.Contact arm is the vitals of handcart, but current contact arm cannot realize the function carrying out in a coupled condition detecting.
Utility model content
The utility model provides one and uses the movable contact arm of circuit breaker flexibly.
For solving the problems of the technologies described above, the movable contact arm of the utility model circuit breaker, comprising: insulating case, described insulating case is connected with support by the pin of its afterbody; Guide rod, described guide rod is arranged on the inside of described insulating case, and described guide rod is scalable design; Slide block, described slide block is arranged on the inside of described insulating case, in described slide block, be provided with contact, and the tail end of described contact is connected with the front end of described guide rod; Binding post, described binding post is arranged on the front end of described insulating case; Push rod, described push rod is arranged on the tail end of described slide block.
Described guide rod comprises: the first sleeve pipe; Second sleeve pipe, described second casing pipe sleeve is located at the lower outside of described first sleeve pipe; Also overlap at the lower outside of described second sleeve pipe and have the 3rd sleeve pipe to the n-th sleeve pipe, wherein n be more than or equal to 3 natural number; Described first sleeve pipe, described second sleeve pipe to described n-th sleeve pipe is connected to form total sleeve pipe.
The bottom of described n-th-2 sleeve pipe is overlapping with described (n-1)th sleeve pipe top; Wherein n be more than or equal to 3 natural number.
Positioning sleeve and lower positioning sleeve is respectively equipped with at the two ends of described total sleeve pipe.
The diameter of described lower positioning sleeve is greater than the overall diameter of described first sleeve pipe be adjacent; The diameter of described upper positioning sleeve is greater than the overall diameter of described (n-1)th sleeve pipe be adjacent; Wherein n be more than or equal to 3 natural number.
Slide block in the movable contact arm of the utility model circuit breaker can slide in insulating case, and the guide rod in slide block is scalable design, and in the moving process of slide block, the degree of guide rod can be stretched, when the front end of contact is connected with binding post, and contact arm work.When required, slide block can move backward at slide block, contact and binding post being disconnected, so just realizing the function that contact arm carries out when not extracting detecting, avoid the plug repeatedly of contact arm.And the movement of slide block has been come by the push rod of rear end.

Embodiment
Below in conjunction with accompanying drawing, the movable contact arm of the utility model circuit breaker is described in further detail.
As shown in Figure 1 and Figure 2, the movable contact arm of the utility model circuit breaker, being comprised: the insulating case 1 be connected with support by pin 2.Slide block 4 is arranged on the inside of insulating case 1, is provided with contact 5 in slide block 4, and the tail end of contact 5 is connected with the front end of the guide rod 3 of insulating case 1 afterbody.And slide block 4 is by the promotion realization of push rod 7 and being communicated with or disconnecting of binding post 6.
Guide rod 3 is wherein scalable design, comprises interconnective first sleeve pipe 8, second sleeve pipe 9, the 3rd sleeve pipe 10 to the n-th sleeve pipe 11, wherein n be more than or equal to 3 natural number.The lower outside that second sleeve pipe 9 is set in the lower outside of the first sleeve pipe 8, the 3rd sleeve pipe 10 is set in the second sleeve pipe 9, the like.
Positioning sleeve 12 and lower positioning sleeve 13 is respectively equipped with at the two ends of guide rod 3.The diameter of upper positioning sleeve 12 and lower positioning sleeve 13 is greater than the overall diameter of the sleeve pipe be adjacent, in order to fixing guide rod 3.
Slide block in the movable contact arm of the utility model circuit breaker can slide in insulating case, and the guide rod in slide block is scalable design, and in the moving process of slide block, the degree of guide rod can be stretched, when the front end of contact is connected with binding post, and contact arm work.When required, slide block can move backward at slide block, contact and binding post being disconnected, so just realizing the function that contact arm carries out when not extracting detecting, avoid the plug repeatedly of contact arm, and the movement of slide block has been come by the push rod of rear end.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
