[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-5 As shown, this embodiment discloses a busbar plug-in locking device for a power distribution cabinet, including a first connector 1, a second connector 2, and a third connector 3. The first connector 1 includes a first plate 11 and a socket 12; the second connector 2 includes a second plate 21 and a first plug 22; and the third connector 3 includes a third plate 31 and a second plug 32. The first connector 1, the second connector 2, and the third connector 3 are integrally formed and are made of plastic. The first connector 1, the second connector 2, and the third connector 3 are injection molded together. The first plate 11 and the second plate 21 are connected by the first connecting strip 4, and the second plate 21 and the third plate 31 are connected by the second connecting strip 5. The thickness of the first connecting strip 4 and the second connecting strip 5 is less than the thickness of the first plate 11 and the second plate 21. The first connecting strip 4 and the second connecting strip 5 can be bent and deformed. The second connecting piece 2 and the third connecting piece 3 are folded towards the first connecting piece 1 in two different directions. The second connecting piece 2 can be inserted into the first connecting piece 1, and the third connecting piece 3 can be inserted into the second connecting piece 2. The three connecting pieces can be locked and fixed together.

[0024] The busbar 101 is generally a horizontally extending strip, and the sub-busbar 102 is generally set perpendicular to the busbar 101. The sub-busbar 102 is in close contact with the side wall of the busbar 101. The busbar 101 is provided with a first through hole 1011, and the sub-busbar 102 is provided with a second through hole 1021. The first through hole 1011 and the second through hole 1021 are aligned. The first connector 1 and the second connector 2 are located on the sides of the busbar 101 and the sub-busbar 102, respectively. The first connecting strip 4 is located on the side opposite to the extension direction of the installed sub-busbar 102, so as to avoid the installation direction of the sub-busbar 102.

[0025] The socket 12 is partially inserted into the first through hole 1011. The socket 12 is cylindrical, and the outer diameter of the socket 12 corresponds to the inner radial direction of the first through hole 1011, which can position and limit the first connector 1. The first plate 11 abuts against the busbar 101. The first plug 22 is inserted into the second through hole 1021. The first plug 22 includes a first post segment 221 and a second post segment 222. The first post segment 221 is connected to the second plate 21. The retaining ring is located in the second post segment 222. The first post segment 221 is inserted into the second through hole 1021. The outer diameter of the first post segment 221 corresponds to the inner diameter of the second through hole 1021, which can position and limit each other. The second plate 21 abuts against the sub-busbar 102. After the first connector 1 and the second connector 2 are inserted and locked, the sub-busbar 102 and the busbar 101 are clamped and limited by the first plate 11 and the second plate 21.

[0026] The outer wall of the second column segment 222 is provided with a plurality of first retaining rings 122 along the axial direction. The center of the socket 12 is provided with a first insertion hole 121, which is a connecting hole. The inner wall of the first insertion hole 121 is provided with a plurality of second retaining rings 2221 corresponding to the first retaining rings 122. Part of the first insertion post 22 is inserted into the first insertion hole 121. The first retaining ring 122 includes two ring sidewalls. The ring sidewall facing the second plate 21 is parallel to the second plate 21, and the ring sidewall away from the second plate 21 is inclined. When the first insertion post 22 is inserted into the socket 12, the inclined ring sidewall can guide the first retaining ring 122 to pass over the second retaining ring 2221. The ring sidewall parallel to the second plate 21 can limit the axial direction and fix the first retaining ring 122 and the second retaining ring 2221 to each other.

[0027] The second column segment 222 is tubular and includes multiple connecting grooves 224. The connecting grooves 224 are distributed in a ring on the side wall of the second column segment 222. A deformable part is formed between two adjacent connecting grooves 224. The deformable part can be elastically deformed. The deformable second column segment 222 can facilitate the first retaining ring 122 to pass over the second retaining ring 2221 and facilitate the first insertion post 22 to be inserted into the socket 12 for connection.

[0028] like Figure 4As shown, the second plate 21 includes a deformable ring 23, which connects the first plug 22 and the second plate 21. The thickness of the deformable ring 23 is less than the thickness of the second plate 21. The deformable ring 23 allows the first plug 22 and the second plate 21 to be misaligned axially. The deformable ring 23 can elastically deform. When the first plug 22 and the socket 12 are plugged in, the first plug 22 is continuously inserted away from the second plate 21 by pressing the first plate 11 and the second plate 21 with a finger. Due to the action of the deformable ring 23, the first plug 22 can be inserted further into the socket 12. The force of the deformable ring 23 can pull the first plug 22 back tight. Since the thickness of the busbar 101 and the sub-busbar 102 may be different, the degree of engagement between the first plug 22 and the socket 12 may also be different. The elastically deformable deformable ring 23 can eliminate the error of the first plug 22 and the socket 12 being plugged in by the busbar 101 and the sub-busbar 102 of different thicknesses.

[0029] The second plate 21 includes a protrusion 225 located on the back side of the first plug 22. The protrusion 225 is arc-shaped and provides a pressing feel when the second connector 2 is pressed, making it convenient to press the back side of the first plug 22 when the first plug 22 is plugged into the socket 12.

[0030] The first insertion post 22 has a second insertion hole 223 at its center. A portion of the second insertion post 32 can be inserted into the second insertion hole 223. The outer wall of the second insertion post 32 has multiple protruding rings 321, which are arranged along the axial direction of the second insertion post 32. The sidewalls of the protruding rings 321 are arc-shaped. The difference between the maximum diameter of the protruding rings 321 and the diameter of the second insertion post 32 is L, which is 0.4 mm. The protruding rings 321 and the second insertion hole 223 are interference-fitted. After the first insertion post 22 and the socket 12 are stably engaged, the second connecting strip 5 is bent. The second plug 32 is inserted into the second socket 223. Since the first plug 22 and the second plug 32 are made of plastic, the second plug 32 can be inserted into the second socket 223 by applying force to make an interference fit. The second plug 32 can support the deformable part and prevent the first plug 22 and the socket 12 from separating. The second plug 32 is at least partially inserted into the range of the first socket 121 to ensure that the second plug 32 can support the deformable part located in the first socket 121, so that the first plug 22 and the socket 12 are more tightly connected.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
