Meanwhile, the first flexible element 16 and the second flexible element 18 are respectively sleeved on the operation portion 124 and the second connecting element 14, and seal gaps between the operation portion 124 and the structure 20 to be connected and gaps between the second connecting element 14 and the structure 20 to be connected. Therefore, the corrosion of the external moisture to the first connecting piece 12 and the second connecting piece 14 is effectively prevented, so that the service life is prolonged, and the connection reliability is improved.
It should be noted that the structure to be connected 20 is generally two components to be connected together, and in the power system, the two components are a ground lead of the power equipment and a ground wire connection of the grounding device, respectively. Of course, in other application areas, other connecting members are possible.
In some embodiments, the connecting portion 122 is substantially cylindrical, the first end and the second end of the connecting portion 122 are respectively ends of two bottom surfaces of the cylindrical connecting portion 122, and the first end and the second end are not limited to end surfaces, and may be positions close to the bottom surfaces. Further, the side of the connecting portion 122 is provided with an external thread.
In some embodiments, the operation portion 124 defines a plurality of first engaging grooves, the first engaging grooves extend along a longitudinal direction of the connection portion 122, and the plurality of first engaging grooves are disposed at intervals along a circumferential direction of the connection portion 122 on the operation portion 124. The form of the opening of the first engaging groove defined by the longitudinal direction and the circumferential direction of the connecting portion 122 is not described herein, because the form of the opening of the first engaging groove can be described more clearly by the structure of the connecting portion 122. Further, the operation portion 124 is hemispherical and has a spherical surface and a plane, the connection portion 122 is fixedly connected to the plane, and the plurality of first clamping grooves are circumferentially arranged on the spherical surface at intervals.

In some embodiments, the second connecting member 14 defines a threaded hole, and the connecting portion 122 is threaded into the threaded hole. Specifically, the threaded hole extends through the second connector 14 and is located at an intermediate position of the second connector 14. Thus, in combination with the above structure, it can be known that the first connecting member 12 and the second connecting member 14 are matched by bolts and nuts, and the first connecting member 12 is a bolt and the second connecting member 14 is a nut. The operation portion 124 and the second connecting member 14 are hemispherical, so that a conventional tool cannot be operated, and the possibility of being stolen after being installed outside is effectively avoided. Meanwhile, the operation part 124 and the second connecting member 14 have the same size, and the same number of clamping grooves are formed in the upper part, and the arrangement mode is the same, so that the operation part 124 and the second connecting member 14 can use the same intermediate tool, and the complexity of the device is reduced.

Further, the sealing plug 164 is matched to the second opening to ensure sealing effect.
It should be noted that, the first protective sleeve 162 and the second protective sleeve in the above two embodiments may be the same or different, and when the two are the same, because the second protective sleeve needs to allow the connecting portion 122 to pass through, two openings need to be provided, one opening is used for sheathing the operating portion 124 or the second connecting member 14, and the other opening is used for allowing the connecting portion 122 to pass through, so that the two protective sleeves may adopt the same manufacturing process; when the two are different, the first protection cover 162 only needs to be provided with an opening for covering the operation portion 124.
In some embodiments, in order to improve the sealing performance between the first and second protection sleeves 162 and the structure 20 to be connected, the contact positions of the first and second protection sleeves 162 and the structure 20 to be connected are provided with protrusions, so that the first and second protection sleeves 162 and the structure 20 to be connected are in sufficient contact, and the sealing performance is further improved.

Further, the sealing plug 164 is circular and has two layers, wherein the diameter of one layer matches the diameter of the first hole, and the diameter of the other layer matches the diameter of the second hole, so that the sealing plug 164 is completely inserted into the second opening, and the sealing effect is ensured. In a popular way, the second opening is stepped, and the caliber of the side close to the second inner cavity is larger, and the corresponding sealing plug 164 is also stepped to match with the two calibers respectively, so as to improve the sealing effect.
In some embodiments, the connecting device further includes two protection parts 19, and the two protection parts 19 are respectively disposed between the operating part 124 and the structure to be connected 20 and between the second connecting part 14 and the structure to be connected 20 to prevent the structure to be connected 20 from being damaged during the installation process. Specifically, the guard 19 is a gasket.
In some embodiments, the first connector 12, the second connector 14, the guard 19, and the intermediate tool may be made of carbon steel, stainless steel, or the like; the first flexible member 16 and the second flexible member 18 may be made of a sealing material such as rubber or silicon rubber having a certain aging resistance.
