[0031] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the specific implementation mode and the accompanying drawings.

[0032] The terms used in the present invention are those general terms that are currently widely used in the art in consideration of the functions of the present invention, but these terms may change according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0033] Referring to Figure 1 , this embodiment provides an electrical connection mechanism, including a connection part 100, including a first connecting member 101 and a second connecting member 102 that can be connected; the two connecting members can be connected and disassembled in various ways, and after connection, the first connecting member 101 and the second connecting member 102 can be fixed together.

[0034] The electrical connection mechanism further includes a contact portion 200, which includes a first contact member 201 and a second contact member 202 respectively provided on the first connecting member 101 and the second connecting member 102. The contact portion 200 is made of a conductive material, and the manufacturing materials include but are not limited to various conductive metals. When the first connecting member 101 and the second connecting member 102 are in a separated state, the first contact member 201 and the second contact member 202 do not contact each other and cannot form an electrical connection relationship. When the first connecting member 101 and the second connecting member 102 are connected, an electrical connection relationship can be formed through the contact of the first contact member 201 and the second contact member 202.

[0035] Please refer to Figure 2 , the distance between the first connecting member 101 and the second connecting member 102 is the connection spacing. When the first connecting member 101 and the second connecting member 102 are being connected, the connection spacing gradually decreases. Before the connection spacing equals 0, the first contact member 201 and the second contact member 202 are in contact to form an electrical connection; at least one of the first contact member 201 and the second contact member 202 can displace relative to the first connecting member 101 and the second connecting member 102. When one of the contact members of the contact portion 200 displaces, it can receive a force towards the other contact member.

[0036] When the first connecting member 101 and the second connecting member 102 are completely connected, the connection spacing is 0. Therefore, before the first connecting member 101 and the second connecting member 102 are completely connected, the first contact member 201 and the second contact member 202 start to contact. After being completely connected, a force can be applied to the first contact member 201 or the second contact member 202, so that the first contact member 201 and the second contact member 202 maintain a tightly pressed state, making the connection between the first contact member 201 and the second contact member 202 stable.

[0037] Such as Figure 3 , the end of the first connecting member 101 has an inner cavity 1011, the end of the second connecting member 102 has an outer protrusion 1021, the bottom surface of the inner cavity 1011 is the first surface M1, the first contact member 201 is installed in the inner cavity 1011, the surface of the first contact member 201 away from the first surface M1 is the second surface M2, the protruding surface of the second connecting member 102 is the third surface M3, the second contact member 202 is installed on the third surface M3, and the surface of the second contact member 202 away from the third surface M3 is the fourth surface M4. When the positions of the first connecting member 101 and the second connecting member 102 are fixed, the distance L1 between the second surface M2 and the fourth surface M4 is less than the connection spacing L2 between the first surface M1 and the third surface M3. When connecting, the outer protrusion 1021 of the second connecting member 102 can extend into the inner cavity 1011 of the first connecting member 101, so that the first contact member 201 and the second contact member 202 are in contact.

[0038] As an alternative embodiment, one of the contact members in the contact portion 200 is capable of displacement relative to the first connecting member 101 and the second connecting member 102. For example, Figure 1 , the first contact member 201 is fixed to the first connecting member 101, while the second contact member 202 is slidably mounted on the second connecting member 102. When the first connecting member 101 and the second connecting member 102 are connected, the first contact member 201 will first come into contact with the second contact member 202 to complete the electrical connection.

[0039] In another embodiment, both contact members in the contact portion 200 are capable of displacement relative to the first connecting member 101 and the second connecting member 102. For example, Figure 4 , the first contact member 201 is movable relative to the first connecting member 101, and the second contact member 202 is movable relative to the second connecting member 102. When the first contact member 201 and the second contact member 202 are in contact, both the first contact member 201 and the second contact member 202 are movable. When the first contact member 201 moves, it is subjected to a thrust force in the direction of the second contact member 202, and when the second contact member 202 moves, it is subjected to a thrust force in the direction of the first contact member 201, so that the first contact member 201 and the second contact member 202 are kept in a tightly pressed state. The thrust forces received by the first contact member 201 and the second contact member 202 can be generated due to their own elasticity, causing deformation when being pushed, or because the first contact member 201 and the second contact member 202 are connected to an external elastic structure, pressing the elastic structure when moving, and the thrust force is generated by the deformation of the elastic structure.

[0040] As an alternative embodiment, for example, Figure 5 , an elastic portion 300 is further included. When the first contact member 201 or the second contact member 202 is displaced, it can press the elastic portion 300. The elastic portion 300 is disposed between the movable contact portion 200 and the connecting portion 100. For example, when the first contact member 201 is movable, the elastic portion 300 is disposed between the first contact member 201 and the first connecting member 101. When both the first contact member 201 and the second contact member 202 are movable, the elastic portion 300 is disposed between the first contact member 201 and the first connecting member 101, and between the second contact member 202 and the second connecting member 102. In this way, whether the first contact member 201 or the second contact member 202 moves, it can press the elastic portion 300, and the deformation of the elastic portion 300 will exert a reaction force on the first contact member 201 and the second contact member 202, thereby pressing the first contact member 201 and the second contact member 202 tightly.

[0041] As an alternative embodiment, for example, Figure 5, the elastic part 300 is a spring, which is arranged on the connecting part 100 and abuts against the contact part 200. One end of the spring contacts the second connecting piece 102, and the other end of the spring is also connected to the second contact piece 202. Therefore, when the second contact piece 202 contacts the first contact piece 201, the first contact piece 201 can apply a thrust force towards the spring direction to the second contact piece 202, causing the spring to be compressed. Thus, the spring applies an elastic force towards the first contact piece 201 direction to the second contact piece 202 to help the first contact piece 201 and the second contact piece 202 to be tightly pressed together.

[0042] In another embodiment, the elastic part 300 is integrally formed with the first connecting piece 101 or the second connecting piece 102, such as Figure 6 , the elastic part 300 is a sheet-like structure. One end of the sheet-like structure is a forming end 301 which is integrally formed with the second contact piece 202, and the other end of the sheet-like structure is a contact end 302 which contacts the second connecting piece 102. In this embodiment, the sheet-like structure has a certain curvature. When pressed, the sheet-like structure deforms, causing the curvature of the sheet-like structure to increase. The sheet-like structure applies a reaction force to the second contact piece 202 to press the second contact piece 202 towards the first contact piece 201.

[0043] As an alternative embodiment, the first connecting piece 101 and the second connecting piece 102 are connected by threads, such as Figure 2 , in this embodiment, the first connecting piece 101 and the second connecting piece 102 are structures with a circular cross-section, and threads are provided on both the first connecting piece 101 and the second connecting piece 102. The first connecting piece 101 and the second connecting piece 102 are connected by threads.

[0044] As an alternative embodiment, in order to be able to connect more quickly, such as Figure 7 , the first connecting piece 101 and the second connecting piece 102 are connected by a buckle 400. A clamping groove 1012 is provided on the first connecting piece 101, and a buckle 400 is provided on the second connecting piece 102. The first connecting piece 101 and the second connecting piece 102 are connected by the clamping groove 1012 and the buckle 400. Among them, in order to improve the stability of the clamping connection, the buckle 400 is also connected with a pushing spring 500. The function of the pushing spring 500 is to apply a thrust force to the buckle 400 so that the buckle 400 remains clamped inside the clamping groove 1012.

[0045] In another embodiment, such as Figure 8, the first connecting member 101 and the second connecting member 102 are connected by a buckle 400; the buckle 400 includes a first buckle body 401 and a second buckle body 402, and an elastic part 300 is arranged between the first buckle body 401 and the second buckle body 402; when the first connecting member 101 and the second connecting member 102 are connected, the elastic force of the elastic part 300 can push the first buckle body 401 to complete the buckling connection of the first connecting member 101 and the second connecting member 102.

[0046] In this embodiment, the elastic part 300 is no longer in direct contact with the first contact member 201 or the second contact member 202. As Figure 9 , both the first buckle body 401 and the second buckle body 402 are independent buckle bodies, both are installed on the second connecting member 102, and both can slide relative to the second connecting member 102. A sliding cavity 1022 is formed on the second connecting member 102, and openings 1023 are formed at both ends of the sliding cavity 1022. The first buckle body 401 and the second buckle body 402 can respectively extend from the two openings 1023 to the outside of the sliding cavity 1022, and limiting structures 403 are arranged on both the first buckle body 401 and the second buckle body 402. The limiting structure 403 can prevent the first buckle body 401 and the second buckle body 402 from completely disengaging from the sliding cavity 1022 through the openings 1023, and the end of the second buckle body 402 extending outside the sliding cavity 1022 abuts against the second contact member 202. Therefore, when the first connecting member 101 and the second connecting member 102 are docked, the first contact member 201 can push the second contact member 202, causing the second contact member 202 to slide. During the sliding process, the second buckle body 402 can be pushed, causing the second buckle body 402 to squeeze the elastic part 300, the elastic part 300 deforms, and the first buckle body 401 is pushed. When the position of the first buckle body 401 corresponds to the position of the card slot 1012 on the first connecting member 101, the first buckle body 401 can be snapped into the inside of the card slot 1012 to complete the connection of the first connecting member 101 and the second connecting member 102. Therefore, by using the same elastic part 300, not only can the first connecting member 101 and the second connecting member 102 be stably connected, but also the first contact member 201 and the second contact member 202 can maintain a good contact relationship.

[0047] The present invention also discloses a multi-functional operating rod for power outage inspection and grounding wire hanging, including the above-mentioned electrical connection mechanism; it further includes; an operating head 600, which includes a grounding hook 601; a holding part 700, which is provided with a grounding wire 701; an extension section 800, which can be connected to the operating head 600 and the holding part 700 through a connecting part 100; when the operating head 600, the holding part 700, and the extension section 800 are connected through the connecting part 100, the contact part 200 can electrically connect the grounding hook 601 and the grounding wire 701.

[0048] In this embodiment, a first connecting member 101 and a first contact member 201 are provided on the operating head 600, and the grounding hook 601 and the first contact member 201 are connected by an electric wire. At one end of the extension section 800, a first connecting member 101 and a first contact member 201 are provided, and at the other end, a second connecting member 102 and a second contact member 202 are provided. On the extension section 800, the first contact member 201 and the second contact member 202 are also connected by an electric wire. Therefore, the extension section 800 is connected to the operating head 600 through the electric connection mechanism in the present invention, and can also be connected to another extension section 800 through the extension section 800.

[0049] A second connecting member 102 and a second contact member 202 are provided on the holding portion 700, and the grounding wire 701 is connected to the second contact member 202. The holding portion 700 can also be connected to the extension section 800 through the electric connection mechanism. Therefore, by using the electric connection mechanism to connect the operating head 600, the holding portion 700, and the extension section 800, the length of this operating rod can be adjusted according to actual usage requirements. At the same time, by connecting the holding portion 700 and the operating portion through the extension section 800, the grounding hook 601 and the grounding wire 701 can be conductively connected.

[0050] In addition, on the operating head 600, an electroscope 602 and an operating structure 603 are further provided. Among them, the electroscope 602 is provided at the end of the operating head 600. In addition, the operating structure 603 can be installed on the radial side wall of the operating head 600. The operating structure 603 can be fixed perpendicular to the axis direction of the operating head 600 on the radial side wall of the operating head 600, or can be rotatably installed on the radial side wall of the operating head 600.

[0051] In the actual operation process, this multi-functional operating rod for power outage inspection and grounding can be used to contact and operate the switch through the operating structure 603 for power outage operation. After the power outage, the electroscope 602 can be used for power inspection. After the power inspection is completed, the grounding hook 601 can be hung on the equipment or line to be operated, and grounding can be achieved.

[0052] By using this multi-functional operating rod for power outage inspection and grounding, a single rod can complete three operation processes of power outage, power inspection, and grounding, and it is not necessary to carry too many tools during operation. In addition, the multi-functional operating rod for power outage inspection and grounding can be disassembled, and can be disassembled into a smaller length for easier carrying when carried.

[0053] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
