Description

Technical Field

[0001] This utility model relates to the field of access device technology, specifically to a fast power supply device for a distribution network terminal. Background Art

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electrical energy generated by generators before feeding it into the high-voltage power grid. During routine use, substations and high-voltage switchgear require inspection and maintenance, necessitating connections via external connectors.

[0003] Patent CN202321865845.8 discloses an emergency power supply device that uses an independently set operating lever to drive the movable seat to move, avoiding accidental loosening of the movable seat when plugging or unplugging external connectors and ensuring the stability of power transmission. Its drawback is that, to ensure the movable seat's stable clamping of the busbar, a torque-controlled tool is required for tightening. Traditional torque-controlled tools have relatively complex internal structures, need to achieve a constant torque slippage and release function, and require periodic factory maintenance and torque value testing.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the scope of protection of this utility model.

[0025] It should be noted that when a component is referred to as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable, such as through socketing, snap-fitting, integral molding, welding, etc., which are achievable in the prior art and will not be elaborated further here. When a component is perpendicular or approximately perpendicular to another component, it means that the ideal state is perpendicularity, but due to manufacturing and assembly effects, there may be a certain degree of perpendicularity error. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only and do not represent the only possible implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The terms "first" and "second" in this utility model do not represent specific quantities or orders, but are merely used to distinguish names.

[0028] Combined with appendix Figures 1-4 This embodiment of a power distribution terminal fast power supply device includes a fixed base 1, a first conductive contact 2, a movable base 3, a second conductive contact 4, a power supply connector 5, and an operating rod 6. The operating rod 6 is arranged along the straight line of the second conductive contact 4 relative to the first conductive contact 2. The operating rod 6 includes a threaded section 61. A threaded hole that mates with the threaded section 61 is provided through the fixed base 1. One end of the threaded section 61 abuts against the movable base 3. A screwing part 62 is connected to the threaded section 61 through a break-off part 63. The screwing part 62 is the force-applying part. The diameter of the break-off part 63 is significantly smaller than the diameters of the threaded section 61 and the screwing part 62. It will break when subjected to a large force, thereby disconnecting the threaded section 61 and the screwing part 62.

[0029] This power distribution terminal quick power supply device achieves a constant torque locking function through the integrated screw-off structure operating rod 6, ensuring that the first conductive contact 2 and the second conductive contact 4 form a stable and reliable clamping power supply connection to the busbar, eliminating the need for traditional constant torque tools and eliminating the need for periodic return to the factory for maintenance and torque value testing.

[0030] As a preferred embodiment of this utility model, the threaded section 61 is connected to the unscrewed section 63 through the connecting part 64. The diameter of the connecting part 64 is close to the diameter of the threaded section 61, serving as both a transitional connection between the two and a force application point when the operating lever 6 is subsequently disassembled.

[0031] As a preferred embodiment of this utility model, to prevent the operation lever 6 from being maliciously disassembled using general-purpose tools such as pliers, thus affecting the stability of the power supply, the connecting part 64 is designed as an irregularly shaped screw-on structure. This structure is defined as having no two relatively parallel planes on its surface (for example, the triangular prism structure used in this embodiment, or a pentagonal prism, etc.). This design prevents traditional tools such as pliers from effectively clamping and applying force to rotate it.

[0032] As a preferred embodiment of this invention, the edge of the connecting part 64 is rounded, further enhancing the anti-pinch performance. However, the rounded edge makes the tool more prone to slippage during clamping.

[0033] As a preferred embodiment of this utility model, the operating lever 6 is covered with a protective sleeve 7. The protective sleeve 7 is a cylindrical structure with a diameter larger than that of the operating lever 6, and it is connected to the fixed base 1. Its functions are twofold: first, to protect the operating lever 6; and second, to restrict the operating space so that the disassembly and assembly of the operating lever 6 must rely on special tools.

[0034] As a preferred embodiment of this utility model, it further includes an assembly tool 8 that cooperates with the screwing part 62. The assembly tool 8 includes a first grip part 81; a first connector 82, rotatably connected to the first grip part 81, the first connector 82 having a screwing groove that cooperates with the screwing part 62, the first connector 82 and the screwing part 62 being sleeved and anti-rotationally engaged; and a first linkage part 83, fixedly connected to the first grip part 81 and connected to the first connector 82 through a first one-way bearing 84. The outer diameter of the first linkage part 83 matches the inner diameter of the first one-way bearing 84, and the outer diameter of the first one-way bearing 84 matches the inner diameter of the connection part of the first connector 82 (the first connector 82 has a connection groove that cooperates with the first one-way bearing 84, the connection groove and the aforementioned screwing groove being arranged opposite to each other). The first linkage part 83 can drive the first connector 82 to rotate in one direction through the first one-way bearing 84, and this direction is consistent with the screwing installation direction of the screwing part 62.

[0035] As a preferred embodiment of this utility model, it also includes a disassembly tool that cooperates with the connecting part 64. The structure of the disassembly tool is basically the same as that of the assembly tool 8. The main difference is that the connector on the disassembly tool is inserted into the connecting part 64 and is anti-rotationally engaged, and the rotational direction of the disassembly tool is opposite to that of the assembly tool 8.

[0036] In this embodiment, both the screwing part 62 and the connecting part 64 are irregularly shaped structures and require special tools to operate. The assembly tool 8 can only be used to install the operating rod 6, and the disassembly tool can only be used to disassemble the operating rod 6. The operating rod 6 is scrapped after a single use, which ultimately makes this power distribution terminal fast power supply device a disposable product, because there is a great risk of electric shock if the product is used repeatedly.

[0037] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
