[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , an embodiment provided by the utility model:

[0022] The busbar connector side ear includes a body, which includes a side ear plate 1. A partition 11 is provided on the inner side of the side ear plate 1. The side ear plates 1 are arranged on both sides of the partition 11, so that the partition 11 can clamp and fix the busbar, thereby realizing the connection between the busbars;

[0023] The surface of the side ear plate 1 is provided with a clamping mechanism, which includes an upper cover plate 2, which is provided on the outside of the side ear plate 1, and a fixing rod 21 is fixedly connected to the inner surface of the upper cover plate 2. The top of the partition plate 11 is fixedly connected to a first connecting block 22, and the top of the side ear plate 1 is fixedly connected to a second connecting block 23. The inner side of the upper cover plate 2 is movably connected with a forward and reverse screw 24, and a lower cover plate 25 is provided at the bottom end of the upper cover plate 2. Through the rotation of the forward and reverse screw 24, the side ear plate 1 can move in opposite directions under the action of the forward and reverse screw 24. Through the approach of the two groups of side ear plates 1, the partition 11 can move and can clamp the busbar, which facilitates the fixation of the busbar, making it more stable when connecting the busbar, and no tools are needed to tighten the bolts.

[0024] Furthermore, the fixing rods 21 are fixedly connected to the inner surface of the upper cover plate 2 in two groups, and the first connecting block 22 is movably connected to the fixing rods 21. The cooperation between the fixing rods 21 and the first connecting block 22 can limit the movement of the partition 11 in the side ear plate 1, thereby ensuring the stability of the movement of the partition 11 and avoiding the deflection or tilt of the partition 11, so that the partition 11 has a better fixing effect on the busbar.

[0025] Furthermore, the second connecting block 23 and the fixed rod 21 are movably connected, the side ear plate 1 is movably connected through the thread and the forward and reverse screw 24, and the partition 11 and the forward and reverse screw 24 are movably connected. Through the setting of the second connecting block 23, when the forward and reverse screw 24 rotates, the side ear plate 1 can move stably under the action of the forward and reverse screw 24, thereby facilitating the movement of the side ear plate 1 to realize the fixation of the partition 11 to the busbar.

[0026] Furthermore, a connecting mechanism is provided on the surface of the lower cover 25, which includes a positioning block 3, which is fixedly connected to the upper surface of the lower cover 25, a positioning groove 31 is provided on the inner side of the upper cover 2, and a movable groove 32 is provided on the inner wall of the positioning groove 31, a spring 33 is fixedly connected to the inner wall of the movable groove 32, and a clamping block 34 is fixedly connected to the surface of the spring 33, a clamping groove 35 is provided on the surface of the positioning block 3, a first rubber pad 36 is fixedly connected to the lower surface of the upper cover 2, and a second rubber pad 37 is fixedly connected to the upper surface of the lower cover 25. Through the arrangement of the first rubber pad 36 and the second rubber pad 37, a tight fit can be achieved when the clamping block 34 and the clamping groove 35 are engaged, and then the connection between the upper cover 2 and the lower cover 25 can be sealed, thereby improving the waterproof performance.

[0027] Furthermore, the positioning blocks 3 are fixedly connected to the lower cover plate 25 in four groups, and the positioning grooves 31 are opened in four groups on the inner side of the upper cover plate 2. By setting the positioning blocks 3 and opening the positioning grooves 31, the connection between the upper cover plate 2 and the lower cover plate 25 can be positioned, and the installation is more accurate. The upper cover plate 2 and the lower cover plate 25 can better surround and protect the side ear plate 1 and the partition plate 11.

[0028] Furthermore, one end of the spring 33 is fixedly connected to the movable groove 32, and the other end of the spring 33 is fixedly connected to the block 34. The block 34 moves inside the movable groove 32. Through the elastic properties of the spring 33, the block 34 can be reset, so that the block 34 can be engaged with the groove 35, and then the positioning block 3 can be fixed in the positioning groove 31, thereby facilitating the connection between the upper cover 2 and the lower cover 25.

[0029] Working principle: When in use, the forward and reverse screws 24 are rotated, and the second connecting block 23 is limited by the fixed rod 21, so that the side ear plate 1 will move horizontally under the action of the forward and reverse screws 24, so that the second connecting block 23 can move on the surface of the fixed rod 21. By bringing the two groups of side ear plates 1 closer to each other, the partition 11 can move accordingly under the action of the side ear plates 1, so that the first connecting block 22 can move on the surface of the fixed rod 21, and thus the partition 11 can be fixed to the busbar;

[0030] When the positioning block 3 and the positioning slot 31 are inserted into the corresponding position, the blocking block 34 is squeezed by the positioning block 3 and moves toward the inner side of the movable slot 32. At this time, the spring 33 is in a contracted state. When the positioning block 3 makes the slot 35 face the blocking block 34 during the insertion process, the blocking block 34 will be reset under the rebound action of the spring 33, thereby achieving the engagement between the blocking block 34 and the slot 35, thereby fixing the positioning block 3. At this time, the first rubber pad 36 and the second rubber pad 37 are tightly fitted, and the sealing connection between the upper cover plate 2 and the lower cover plate 25 can be achieved; when it is necessary to separate the upper cover plate 2 and the lower cover plate 25, the upper cover plate 2 or the lower cover plate 25 is pulled, and the blocking block 34 is forced to move into the movable slot 32 and separate from the blocking slot 35, thereby achieving the separation of the positioning block 3 and the positioning slot 31.

[0031] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
