[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figure 1-4 The plug floating connection structure shown includes a plug-in terminal 1 and a socket terminal 2. The plug-in terminal 1 is provided with two sets of symmetrical first plug tubes 10 and two sets of symmetrical first grooves 11. The socket terminal 2 is provided with a first protrusion 23 adapted to the first plug tube 10 and a plug post 22 adapted to the first groove 11. The plug post 22 and the first groove 11 are auxiliaryly fixed by an auxiliary fixing component.

[0027] A protruding platform is provided on the outer wall of the socket terminal 2. A U-shaped fixing groove 20 is provided on the platform, and a boss that matches the fixing groove 20 is provided on the plug-in terminal 1. A floating seat 4 is slidably connected to the boss. The hole in the middle of the floating seat 4 matches the fixing groove 20. The platform is connected to the floating seat 4 by bolts to achieve fixation.

[0028] In one embodiment of this invention, the boss: a first floating platform 12 and a second floating platform 13 are respectively provided on the outer wall of the socket terminal 2. The second floating platform 13 is connected to the first floating platform 12, and the size of the second floating platform 13 is smaller than that of the first floating platform 12. The cross-sections of the first floating platform 12 and the second floating platform 13 are both U-shaped structures, and the opening of the second floating platform 13 is inwardly convex, realizing the function of a limiting floating seat 4 (e.g. Figure 2 (As shown).

[0029] As one implementation method in this embodiment, the floating seat 4: the size of the floating gimbal 40 is larger than the groove of the second floating platform 13, and a connecting post 41 is provided on the end face of the floating gimbal 40. The connecting post 41 is limited on the second floating platform 13 by the structure of the second floating platform 13, and multiple sets of limiting blocks 42 are provided on the outer wall of the connecting post 41. The radius of the limiting block 42 is larger than the radius of the groove of the second floating platform 13, thereby achieving the purpose of limiting the floating seat 4. When fixing, the bolt is inserted into the threaded hole of the connecting post 41 to achieve the purpose of connecting the plug-in terminal 1 and the socket terminal 2.

[0030] As one implementation method in this embodiment, the auxiliary fixing component has three sets of movable plates 220 on the end face of the insertion post 22, and each set of movable plates 220 has a set of fixing strips 221 on its outer wall. In order to perform preliminary fixing after the insertion post 22 is inserted into the first groove 11, a limiting strip 110 that cooperates with the fixing strip 221 is provided on the inner wall of the first groove 11. When the locking member 3 is inserted between the three sets of movable plates 220, the three sets of movable plates 220 are turned outward, so that the fixing strip 221 bites the limiting strip 110, thereby achieving fixation.

[0031] As one embodiment of this example, the locking component 3 is designed to allow the movable plate 220 to open and the fixing strip 221 to bite the limiting strip 110. The pin 32 is conical, and a cover plate 31 that matches the first groove 11 is provided on the outer end face of the pin 32 so that the first groove 11 can be sealed after the pin 32 is inserted into the three sets of movable plates 220. In order to facilitate the insertion and removal of the pin 32, an end 30 is provided on the outer end face of the cover plate 31 for operation.

[0032] As one embodiment of this invention, a slot 100 is provided on the outer wall of the first insert 10, and a clip 21 is provided on the end face of the socket terminal 2. The clip 21 has an L-shaped structure and its free end is round. When the socket terminal 2 is connected to the plug-in terminal 1, the end of the clip 21 cooperates with the slot 100 to achieve auxiliary positioning and avoid loosening, which could lead to poor contact.

[0033] The working principle of this utility model is as follows: When connecting the plug-in terminal 1 and the socket terminal 2, the plug 22 is inserted into the first groove 11, and the first protrusion 23 is inserted into the first plug tube. During this process, the locking piece 21 cooperates with the slot 100 to achieve initial fixation. Then, the locking piece 3 is inserted into the first groove 11, and the pin 32 is inserted between the three sets of movable plates 220, causing the three sets of movable plates 220 to open outward, so that the fixing strip 221 contacts the limiting strip 110 to achieve secondary fixation. Then, the locking piece 3 is pushed to make the cover plate 31 seal the first groove 11 (to release the limit, simply pull the end 30 outward). After completing the above operations, a bolt is passed through the fixing groove 20, and then the end of the bolt abuts against the threaded hole on the floating seat 4. When the bolt is rotated, the floating seat 4 slides on the first floating platform 12 and the second floating platform 13. With the continuous rotation of the bolt, the floating seat 4 gradually stops moving, thus achieving the connection and fixation of the plug-in terminal 1 and the socket terminal 2.

[0034] The floating seat 4 can slide on the first floating platform 12 and the second floating platform 13 through the connecting column 41, and the floating seat 4 is limited by the limiting block 42 and the floating gimbal 40 to prevent it from falling off.

[0035] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.

[0036] Components not described in detail in this article are existing technologies.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
