Description

Technical Field

[0001] The utility model relates to the technical field of analog circuits, in particular to an analog circuit breaker operating table. Background Art

[0002] The simulated circuit breaker is a complete set of tests for power system power-off protection devices or complete sets of relay protection panels, which can truly simulate the tripping and closing time of the circuit breaker.

[0003] A socket for connecting the power supply and various electrical wires is provided on the operating table. Before the simulated circuit breaker works, one end of the power cord needs to be plugged into the socket, and then the other end needs to be plugged into the socket, so that the simulated circuit breaker can be powered on and work.

[0004] After the plug of the power cord is inserted into the socket, the plug is fixed to the inner wall of the socket by friction. As the plug is plugged in and out repeatedly, the friction between the outer wall of the plug and the inner wall of the socket will decrease, causing the plug to automatically fall off the socket. When the simulated circuit breaker is working, if the power cord is dragged, the plug will be directly separated from the socket, causing the simulated circuit breaker to shut down directly, reducing its stability in use. Utility Model Content

[0005] The purpose of the utility model is to provide a simulated circuit breaker operating console to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 The simulated circuit breaker operating console shown includes a simulated circuit breaker operating console body 101 and a positioning mechanism. A socket seat 102 is provided at the top of the simulated circuit breaker operating console body 101. By inserting one end of the power cord into the socket seat 102 and then inserting the other end of the power cord into the plug board, the simulated circuit breaker operating console body 101 can be powered on and work.

[0022] In a preferred embodiment, a positioning mechanism is arranged above the simulated circuit breaker operating console body 101, and is used to fix the plug inserted into the socket seat 102. The positioning mechanism includes a connecting frame 201, and a plurality of threaded holes 202 are opened on the inner wall of the connecting frame 201. The inner wall of the threaded hole 202 is threadedly connected with a bolt 203 that moves axially along the threaded hole 202. A connecting mechanism is arranged between the connecting frame 201 and the simulated circuit breaker operating console body 101, and a contact mechanism is arranged between the bolt 203 and the plug. When the plug is inserted into the socket seat 102, the bolt 203 is screwed in the threaded hole 202 to move the bolt 203 until the bolt 203 drives the contact mechanism to resist the plug. Now the plug is thinner as it reaches the position of the connecting line, so that the plug can be stably inserted into the socket seat 102. Even if an external force pulls the plug, the plug and the socket seat 102 will not be separated, which ensures that the simulated circuit breaker operating console body 101 can be stably connected to the power supply for use, thereby improving the working stability of the simulated circuit breaker operating console body 101.

[0023] Preferably, the contact mechanism includes a rubber sleeve 701, a socket is provided on one side of the rubber sleeve 701, one end of the bolt 203 is inserted into the inside of the rubber sleeve 701, and after the bolt 203 is screwed in the threaded hole 202, the rubber sleeve 701 is driven to move by the movement of the bolt 203 until the rubber sleeve 701 is against the plug. When the rubber sleeve 701 is connected to the bolt 203, some strong glue can be applied to the socket, and then the bolt 203 is inserted into the socket until the strong glue solidifies to fix the bolt 203 and the rubber sleeve 701, thereby avoiding the phenomenon of the rubber sleeve 701 falling off during the movement of the bolt 203, thereby improving the working stability of the contact mechanism.

[0024] Among them, the connecting mechanism includes a plurality of movable rods 301 fixedly connected to the bottom end of the connecting frame 201, a plurality of movable holes 302 are opened at the top of the simulated circuit breaker operating console body 101, the outer walls of the plurality of movable rods 301 are movably interlaced and connected with the inner walls of the plurality of movable holes 302 respectively, and an elastic mechanism is provided at the bottom end of the movable rod 301. By the movable rod 301 moving in the movable hole 302, the connecting frame 201 can be raised and lowered along the axial direction of the movable rod 301, so that before inserting the plug into the socket seat 102, the connecting frame 201 is pressed first so that the connecting frame 201 is against the top end of the simulated circuit breaker operating console body 101, and then the plug is inserted into the socket seat 102, so as to avoid being blocked by the connecting frame 201 during this process and affecting the insertion of the plug.

[0025] Preferably, the elastic mechanism includes a spring 401 arranged at the bottom end of the movable rod 301, and the spring 401 is used to provide an upward movement tendency to the limiting hole 501. A first limiting mechanism is arranged inside the spring 401. Through the elastic action of the spring 401, 402 always has an upward squeezing force on the movable rod 301, so that the movable rod 301 always has an upward movement tendency, that is, after the plug is inserted into the socket 102, as long as the connecting frame 201 is no longer pressed, the movable rod 301 can be automatically raised under the elastic action of the spring 401, so that the connecting frame 201 is automatically raised for reset, and then the bolt 203 is tightened so that the contact mechanism presses against the plug to complete the positioning, thereby improving the convenience of the positioning mechanism.

[0026] Furthermore, the first limiting mechanism includes a fixed rod 502 fixedly connected to the bottom end of the inner wall of the movable hole 302, and a limiting hole 501 is provided at the bottom end of the movable rod 301. The outer wall of the fixed rod 502 is movably connected with the inner wall of the limiting hole 501, and the spring 401 is sleeved on the outer wall of the fixed rod 502. A second limiting mechanism is provided at the bottom of the movable rod 301, and the fixed rod 502 is limited and guided by the limiting hole 501, so that the movable rod 301 can be stably raised and lowered. At the same time, the spring 401 is limited by the fixed rod 502, so that the spring 401 will not be laterally deformed when compressed, thereby avoiding damage to the spring 401, thereby improving the stability of the use of the spring 401 and extending the service life of the spring 401.

[0027] Furthermore, the second limiting mechanism includes a limiting ring 602 fixedly sleeved on the bottom of the outer wall of the movable rod 301, and an annular groove 601 is opened on the side of the inner wall of the movable hole 302. The outer wall of the limiting ring 602 is slidably connected to the inner wall of the annular groove 601. The outer diameter of the limiting ring 602 is larger than the inner diameter of the movable hole 302, so that the limiting ring 602 cannot pass through the movable hole 302, that is, the limiting ring 602 is always located inside the annular groove 601, thereby preventing the movable rod 301 from separating from the movable hole 302, thereby ensuring the highest position of the connecting frame 201, and ensuring that the bolt 203 can be turned in the threaded hole 202 to stably drive the rubber sleeve 701 to press against the outer wall of the plug, thereby improving the stability of the positioning mechanism.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
