[0020] like Figure 1 As shown, this embodiment discloses an electrical switching device, including a first connecting mechanism 10, a second connecting mechanism 20 and a protection mechanism 30, specifically as follows:

[0021] like Figure 1 and Figure 2 As shown, the first connecting mechanism 10 and the second connecting mechanism 20 are arranged correspondingly in the upper and lower parts. The first connecting mechanism 10 includes a first connecting plate 11 and an electrical quick-plug connection module male head 12 (hereinafter referred to as the male head). The first connecting plate 11 is fixedly connected to an external structure (such as a portable clamp), and the male head 12 is arranged on the side of the first connecting plate 11 facing the second connecting mechanism 20.

[0022] like Figure 3As shown, the second connecting mechanism 20 includes a support 21, a telescopic member 22, a second connecting plate 23 and an electrical quick-plug connection module female head 24 (hereinafter referred to as the female head); the support 21 is installed on the external structure, and the telescopic member 22 is arranged on the support 21. The telescopic member 22 in this embodiment is configured as a double-guide rod cylinder. The double-guide rod cylinder has stable performance and high precision. The telescopic direction of the telescopic member 22 is configured as the height direction; the second connecting plate 23 is horizontally arranged on the telescopic end of the telescopic member 22, and the upper surface of the second connecting plate 23 away from the telescopic member 22 is provided with a female head 24. The female head 24 is arranged corresponding to the male head 12 in the height direction. When the female head 24 is docked with the male head 12 in the height direction, electrical connection can be achieved; in this embodiment, the material of the second connecting plate 23 is an insulating material (such as epoxy resin, glass fiber, etc.), which can ensure the insulation performance of the entire device and avoid safety accidents.

[0023] like Figure 2 and Figure 3 As shown, in some preferred embodiments, a positioning hole 12a is provided on the male connector 12, and a positioning pin 24a is provided on the female connector 24. The positioning pin 24a can be inserted upwardly into the positioning hole 12a along the height direction. In this embodiment, the positioning pin 24a can improve the stability of the male connector 12 and the female connector 24 during the docking process. On the other hand, after the docking is completed, the relative position of the male connector 12 and the female connector 24 in the horizontal direction is restricted by the cooperation between the positioning pin 24a and the positioning hole 12a.

[0024] like Figure 4 As shown, the protective mechanism 30 includes a protective cover 31 and a rotating arm 32; one end of the protective cover 31 is hinged to the second connecting plate 23; one end of the rotating arm 32 is hinged to the protective cover 31, and the other end is hinged to the support 21, and the protective cover 31 is driven to rotate through the telescopic member 22 and is covered above the female head 24.

[0025] like Figure 4 As shown, the protective cover 31 includes a top plate 311 and two side plates 312. The two side plates 312 are relatively arranged on the horizontal sides of the second connecting plate 23 and the female head 24, and the two side plates 312 are respectively hinged to the horizontal sides of the second connecting plate 23, wherein the side plates 312 are vertically arranged; the two side surfaces of the top plate 311 are connected to the two side plates 312. When the male head 12 and the female head 24 are in a separated state, the two side plates 312 are respectively located on the horizontal sides of the female head 24, and the top plate 311 is located directly above the female head 24, thereby protecting the female head 24 by enclosing on three sides.

[0026] In this embodiment, when the male connector 12 and the female connector 24 need to be docked, the telescopic member 22 drives the top plate 311 of the protective cover 31 to gradually rotate and swing to the horizontal side of the female connector 24 to avoid hindering the docking of the female connector 24 and the male connector 12.

[0027] In some preferred embodiments, the top plate 311 and the side plates 312 may be an integral structure, formed into the shape described above by bending. The integral structure has better performance and is easier to process.

[0028] like Figure 4 As shown, one of the two side panels 312 is provided with a first avoidance groove 312a. When the female connector 24 and the male connector 12 are in a docking state, the first avoidance groove 312a can expose at least part of the structure of the female connector 24 in the horizontal direction, and external equipment can pass through the first avoidance groove 312a and be electrically connected to the exposed part of the structure.

[0029] like Figure 4 As shown, in this embodiment, the protective cover 31 also includes a cornice 313. The cornice 313 is connected to the edge of the top plate 311, and the long side of the cornice 313 is connected to the long side of the top plate 311. The cornice 313 is located between the two side plates 312. In addition, the cornice 313 is flush or substantially flush with the edge of the female connector 24. In this embodiment, the cornice 313 and the top plate 311 are an integral structure, and the cornice 313 is bent downward. In the height direction, when the male connector 12 and the female connector 24 are in a docked state, the cornice 313 is located between the upper surface of the female connector 24 and the top plate 311. In other words, from a horizontal perspective, at least a portion of the cornice 313 is located between the upper surface of the female connector 24 and the top plate 311.

[0030] like Figure 4 As shown, in this embodiment, the eaves plate 313 is designed to block and protect the gap between the female head 24 and the top plate 311 from the side, preventing impurities such as welding debris from flying into the gap between the female head 24 and the top plate 311 from the side and then falling onto the female head 24.

[0031] like Figure 4 As shown, in order to prevent the eaves plate 313 from interfering with the positioning pin 24a when the protective cover 31 rotates and withdraws from the female head 24, a second avoidance groove 313a corresponding to the positioning pin 24a is provided on the eaves plate 313.

[0032] like Figure 3 and Figure 4As shown, in this embodiment, there are two rotating arms 32, which are horizontally located on the outside of the two side plates 312. The provision of two rotating arms 32 optimizes the stress state and improves the stability of the structure. The support 21 is provided with two connecting arms 25, which correspond one to one with the rotating arms 32. One end of the connecting arm 25 is provided on the support 21 and extends horizontally. One end of the rotating arm 32 is hinged to the connecting arm 25, that is, the rotating arm 32 is hinged to the support 21 via the connecting arm 25.

[0033] like Figure 4 As shown, the rotating arm 32 includes a first sub-arm 321 and a second sub-arm 322. One end of the first sub-arm 321 and the second sub-arm 322 are connected to form an L-shaped structure. Preferably, the first sub-arm 321 and the second sub-arm 322 are an integral structure formed by bending to form the L-shaped structure, wherein the other end of the first sub-arm 321 is hinged to the connecting arm 25, and the other end of the second sub-arm 322 is hinged to the side plate 312 of the protective cover 31;

[0034] like Figure 4 As shown, in this embodiment, a predetermined angle θ is formed between the first sub-arm 321 and the second sub-arm 322. The predetermined angle θ is between 110 and 140 degrees, for example, 130 degrees. By designing the rotating arm 32 as an L-shaped structure with a large angle, it is possible to easily drive the protective cover 31 to rotate to or away from the female connector 24.

[0035] One working mode of the electrical switching device of this embodiment is as follows: Figure 5 As shown, Figure 5 (a) shows that the electrical switching device is in a docking state, and (b) shows that the electrical switching device is in a disengaged state;

[0036] When docking is required: the telescopic member 22 extends upward, the second connecting plate 23 and the female connector 24 move upward, and during the upward movement of the second connecting plate 23, the protective cover 31 rotates and swings to the side of the female connector 24 with the hinge point between itself and the second connecting plate 23 as the rotation center, thereby making room above the female connector 24. As the telescopic member 22 continues to extend, the female connector 24 is upwardly plugged and connected with the male connector 12, thereby achieving electrical connection;

[0037] When separation is required: the telescopic member 22 is retracted downward, the second connecting plate 23 and the female head 24 move downward, so that the female head 24 is disconnected from the male head 12. As the telescopic member 22 continues to retract, the second connecting plate 23 continues to move downward, and the protective cover 31 rotates and swings to the top of the female head 24 with itself and the second connecting plate 23 as the rotation center, thereby protecting the female head 24 through the protective cover 31.

[0038] The above description is only a specific embodiment of the present application. Those skilled in the art will clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the scope of protection of the present application.
