Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a connector for small reclosing circuit breakers. Background Technology

[0002] like Figure 1 As shown, the existing recloser and circuit breaker are connected by a linkage shaft 3. After the linkage shaft 3 passes through the circuit breaker 2, a certain length needs to be reserved at the end facing the recloser 1 so that the output shaft of the recloser 1 can be inserted into the linkage shaft 3.

[0003] This will cause at least the following problems: when reclosing 1 needs to be replaced, the linkage shaft cannot be pulled out. Therefore, reclosing 1 needs to be moved to the right until it is completely removed from the linkage shaft 3 before it can be removed. Thus, after the circuit breaker 2 and reclosing 1 are assembled in the control box, enough space needs to be reserved at the end of reclosing 1 away from the linkage shaft 3 in order to remove the entire reclosing 1. If the space inside the control box is insufficient, all circuit breakers and reclosing 1 need to be removed in order to replace reclosing 1. Utility Model Content

[0004] The purpose of this utility model is to provide a connector for small reclosing circuits to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connector for a small reclosing circuit breaker, comprising a reclosing circuit breaker and several circuit breakers arranged side by side, and a linkage shaft passing through a handle on the circuit breaker and connecting to the output shaft inside the reclosing circuit breaker; one end of the linkage shaft is provided with a disassembly and assembly part, and by pulling the disassembly and assembly part, the disassembly and assembly part can be pulled out from a receiving cavity provided on the side of the circuit breaker, so as to facilitate the disassembly and assembly of the reclosing circuit breaker.

[0006] As a preferred technical solution of this utility model, the disassembly and assembly part is further provided with a connection hole.

[0007] As a preferred technical solution of this utility model: a crossbar is placed horizontally in the radial direction of the connecting hole.

[0008] As a preferred technical solution of this utility model: the inner wall surface of the connecting hole is provided with threads.

[0009] The beneficial effects of this utility model by adopting the above technical solution are as follows: 1. Since the disassembly and assembly part is set at the end of the linkage shaft away from the reclosing device, when the reclosing device needs to be replaced, the linkage shaft can be pulled out from the receiving groove through the disassembly and assembly part, shortening the length of the linkage shaft facing the reclosing device end, and distributing the space required to disassemble the reclosing device to both sides of the circuit breaker. Therefore, the distance required to move when disassembling the reclosing device can be reduced, so as to facilitate the smooth disassembly of the reclosing device. 2. Since the linkage axis is pulled away from the side away from the reclosing, the disassembly space required for reclosing can be reduced by a very simple solution. This not only facilitates the rapid disassembly of the reclosing, but also allows for the separate disassembly of the reclosing without disassembling other circuit breakers.

[0010] 3. Although the equipment adopts extremely simple solutions, the advantages brought by its extremely simple structure in enterprise production are significant; for example, it can effectively reduce the processing difficulty and cost of the linkage shaft; the assembly process is similar to that of existing linkage shafts, reducing training costs. 4. Although the equipment adopts extremely simple solutions, the advantages brought by the extremely simple structure in enterprise production are prominent. For example, the linkage shaft can be replaced on the old product, making the new and old parts interchangeable. Since the new and old products are interchangeable, the assembly process can be simplified, the debugging time can be reduced, and assembly line operation or automated assembly can be realized, significantly improving production efficiency.

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0014] Please see Figure 2-6 This utility model provides an embodiment of a small reclosing connector, including a reclosing device 1 and several circuit breakers 2 arranged side by side. A linkage shaft 3 passes through a handle 4 on the circuit breaker 2 and connects to the output shaft inside the reclosing device 1. One end of the linkage shaft 3 is provided with a disassembly part 30, and the disassembly part 30 can be pulled out from a receiving cavity 5 on the side of the circuit breaker 2 by pulling the disassembly part 30, so as to facilitate the disassembly and assembly of the reclosing device 1.

[0015] In summary, since the disassembly and assembly part 30 is provided at the end of the linkage shaft 3 away from the reclosing 1, when the reclosing 1 needs to be replaced, the linkage shaft can be pulled out from the receiving groove 5 through the disassembly and assembly part 30, shortening the length of the linkage shaft 5 facing the reclosing end. The space required to disassemble the reclosing 1 is distributed to both sides of the circuit breaker 2, thus reducing the distance that needs to be moved when disassembling the reclosing 1, so as to facilitate the smooth disassembly of the reclosing. Meanwhile, by moving the linkage shaft 3 away from the reclosing 1, the disassembly space required for the reclosing 1 can be reduced through an extremely simple solution. This not only facilitates the rapid disassembly of the reclosing 1, but also allows for the separate disassembly of the reclosing 1 without disassembling other circuit breakers 2.

[0016] Building upon the aforementioned advantages, although the equipment employs extremely simple solutions, the advantages brought by this simple structure in enterprise production are significant. For example, it effectively reduces the processing difficulty and cost of the linkage shaft; the assembly process differs little from existing linkage shafts, reducing training costs; and the linkage shaft can be replaced on older products, making the new and old parts interchangeable. This interchangeability simplifies the assembly process, reduces debugging time, and enables assembly line operations or automated assembly, significantly improving production efficiency.

[0017] Implementation method 1: The disassembly and assembly part 30 is also provided with a connection hole 32. Therefore, needle-nose pliers can be used to insert into the connection hole 32 for connection. By gripping the handle of the needle-nose pliers, the tip of the needle-nose pliers expands outward to achieve the connection between the needle-nose pliers and the connection hole 32.

[0018] Implementation method 2: A horizontal bar 31 is placed horizontally in the radial direction of the connecting hole 32. At this time, a hook can be used to hook the horizontal bar 31 to cause the linkage shaft 3 to separate from the reclosing 1.

[0019] Implementation method 3: The inner wall of the connecting hole 32 is threaded, so it can also be connected to the connecting hole 32 with a bolt, and the bolt can be used to push the linkage shaft 3 to separate from the reclosing 1.

[0020] In summary, through the above three implementation methods, there are at least three ways to disassemble the linkage shaft 3. At the same time, the above three structures are relatively simple and the processing technology is relatively mature, so the disassembly and assembly cost of the linkage shaft 3 will not increase.

[0021] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
