[0024] The present invention will be further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0025] Please refer to Figure 1 and Figure 2 A plug-in connection structure includes a movable conductive clip 10, a fixed conductive clip 20, and a connection structure 30 connecting the movable conductive clip 10 and the fixed conductive clip 20.

[0026] The movable conductive clip 10 and the fixed conductive clip 20 are provided with slots 11. One end of the connecting structure 30 is fixed to the movable conductive clip 10, and the other end of the connecting structure 30 is connected to the fixed conductive clip 20 and can slide along the width direction of the fixed conductive clip 20.

[0027] The copper busbar 100 is arranged in the slot 11 of the fixed conductive clip 20. When another copper busbar 100 is blindly inserted into the slot 11 of the movable conductive clip 10, the movable conductive clip 10 can slide along the width direction of the fixed conductive clip 20, so that even if the position of another copper busbar 100 is offset when inserted, it can be adapted by the sliding of the movable conductive clip 10.

[0028] Please refer to Figure 3 , Figure 4 and Figure 5 The plug-in connection structure 30 further includes a fixed shell 40 and a movable shell 50, wherein a movable installation slot 41 and a fixed installation slot 42 are formed in the fixed shell 40. The movable conductive clip 10 is disposed in the movable shell 50, and the movable shell 50 is movably disposed in the movable installation slot 41. The fixed conductive clip 20 is disposed in the fixed installation slot 42. The connection structure 30 extends out of the movable shell 50 and is slidably connected to the fixed conductive clip 20.

[0029] When another copper busbar 100 is inserted into the movable conductive clip 10 , if there is a deviation, the movable shell 50 moves in the movable mounting slot 41 , and the movable conductive clip 10 follows the movement to adjust its position, thereby stably connecting with the other copper busbar 100 .

[0030] The inner wall of the movable mounting groove 41 is recessed to form a transverse groove 411, and the outer wall of the movable shell 50 is protruding to form a protrusion 51 that cooperates with the transverse groove 411. Through the cooperation between the transverse groove 411 and the protrusion 51, the moving direction of the movable shell 50 and the movable conductive clip 10, that is, the width direction of the movable conductive clip 10, is guided.

[0031] The protrusions 51 are formed on the upper and lower surfaces of the outer wall of the movable shell 50 .

[0032] The movable installation groove 41 and the fixed installation groove 42 are both provided with a notch 43 , and the movable shell 50 is provided with a transition notch 52 , and the transition notch 52 is located in the notch 43 of the movable installation groove 41 .

[0033] The width of the transition notch 52 is smaller than the width of the notch 43 of the movable installation groove 41. Preferably, when the movable housing 50 moves, the transition notch 52 is always kept in the notch 43 of the movable installation groove 41.

[0034] The slot 11 of the fixed conductive clip 20 is located at the notch 43 of the fixed installation groove 42. The slot 11 of the movable conductive clip 10 is located at the transition notch 52 of the movable shell 50. An inclined guide surface 521 is formed at the opening of the transition notch 52. The insertion of the copper bus 100 is guided by the guide surface 521. The guide surface 521 is located on both sides of the opening of the transition notch 52, so that the opening is trumpet-shaped.

[0035] When another copper bar 100 is inserted into the movable conductive clip 10, the guide surface 521 guides the other copper bar 100 into the transition gap 52. Preferably, when the movable housing 50 moves, the transition gap 52 is always kept in the gap 43 of the movable mounting groove 41.

[0036] When another copper bar 100 enters the transition gap 52 , it enters the slot 11 of the movable conductive clip 10 .

[0037] The fixed shell 40 includes an upper fixed shell 44 and a lower fixed shell 45, which are combined to form a movable installation groove 41 and a fixed installation groove 42. The fixed installation groove 42 is used to accommodate the fixed conductive clip 20 and keep the fixed conductive clip 20 immovable.

[0038] The upper fixed shell 44 is formed with a plurality of protruding connecting columns, and the lower fixed shell 45 is formed with a plurality of recessed connecting grooves 451, and the connecting columns are opposite to the connecting grooves 451. When the upper fixed shell 44 and the lower fixed shell 45 are combined, the connecting columns extend into the connecting grooves 451, thereby detachably connecting the upper fixed shell 44 and the lower fixed shell 45.

[0039] The movable shell 50 includes an upper movable shell and a lower movable shell. The upper movable shell and the lower movable shell are combined to form a receiving groove 53. The movable conductive clip 10 is disposed in the receiving groove 53.

[0040] Please refer to Figure 1 , Figure 2 and Figure 6The other end of the connection structure 30 has an upper spring sheet 31 and a lower spring sheet 32 ​​which are opposite to each other. The upper spring sheet 31 and the lower spring sheet 32 ​​form a clamping groove 33 for the fixed conductive clip 20 to be inserted into. In a natural state, the minimum width of the clamping groove 33 is less than the thickness of the fixed conductive clip 20.

[0041] The connection structure 30 and the movable conductive clip 10 are integrally formed. Specifically, the lower spring sheet 32 ​​is bent to the lower side of the upper spring sheet 31 by bending.

[0042] The middle parts of the upper elastic sheet 31 and the lower elastic sheet 32 ​​are concave to form a neck 311. The minimum width of the clamping groove 33 appears at the neck 311.

[0043] The slot 11 of the movable conductive clip 10 is provided at the end of the movable conductive clip 10 away from the fixed conductive clip 20. The slot 11 of the fixed conductive clip 20 is provided at the end of the fixed conductive clip 20 away from the movable conductive clip 10. Thus, the slots 11 of the movable conductive clip 10 and the fixed conductive clip 20 are opposite to each other.

[0044] One end of the connection structure 30 is fixed to one end of the movable conductive clip 10 close to the fixed conductive clip 20 , and the other end of the connection structure 30 is slidably connected to one end of the fixed conductive clip 20 close to the movable conductive clip 10 .

[0045] Preferably, one end of the fixed conductive clip 20 close to the movable conductive clip 10 extends to form an extension portion 21 , and the other end of the connecting structure 30 is slidably connected to the extension portion 21 .

[0046] The extension portion 21 extends the length of the fixed conductive clip 20 at one end close to the movable conductive clip 10 , so as to facilitate the sliding connection of the connecting structure 30 .

[0047] In the above scheme, an elastic clamping piece 12 is provided in the slot 11 of the movable conductive clip 10 and the fixed conductive clip 20. One end of the elastic clamping piece 12 is connected to the bottom of the slot 11, and the other end extends outward close to the inner wall of the slot 11. The middle part of the elastic clamping piece 12 is arched to form an elastic contact 121.

[0048] Two elastic clamping pieces 12 are provided in each of the slots 11, and the two elastic clamping pieces 12 are respectively arranged at the upper and lower parts of the slots 11, and the elastic contacts 121 of the two elastic clamping pieces 12 are opposite to each other up and down. In a natural state, the distance between the two elastic contacts 121 opposite to each other up and down is less than the thickness of the copper busbar 100.

[0049] When plugging, insert the two copper bars into the two slots respectively, and the copper bars contact the elastic contacts of the elastic clamping sheet. Since the distance between the two adjacent elastic contacts is less than the thickness of the copper bar in the natural state, the copper bar will press the two elastic contacts to move in opposite directions during the process, so that the other end of the elastic clamping sheet is supported by the inner wall of the slot, thereby providing support force for the elastic clamping sheet, so that the elastic contact clamps the copper bar, the connection between the elastic contact and the copper bar is stable, and the overcurrent is large. At the same time, since the other end of the elastic clamping sheet is a free end, it can slide slightly along the top holding part to release part of the clamping force, so the clamping force is moderate.

[0050] In the above solution, the other end of the elastic clamping piece 12 is slightly tilted upward to increase the contact area between the elastic clamping piece 12 and the slot 11 .

[0051] Please refer to Figure 7 The present invention also discloses a plug-in connector, including at least one plug-in connection structure, wherein at least one of the plug-in connection structures is stacked up and down. The plug-in connector also includes a tie ring 200, wherein the tie ring 200 is sleeved on at least one of the plug-in connection structures. Specifically, the tie ring 200 is sleeved on a fixed shell 40 of the plug-in connection structure.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
