[0022] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0023] Reference Figures 1 to 3A connection device for a busbar trunking includes two clamping plates 1 respectively disposed on the left and right sides, several insulating plates 2 spaced apart between the two clamping plates 1, a copper plate 3 disposed on the insulating plate 2, and a locking bolt 4 for fixing the clamping plates 1 and the insulating plate 2. The insulating plate 2 has a slot 21 on its side for installing the copper plate 3. The insulating plate 2 has a limiting plate 5 that can press the copper plate 3 into the slot 21. The limiting plate 5 includes a first limiting plate 51 disposed on the upper side of the insulating plate 2 and located to the left of the locking bolt 4, and a second limiting plate 52 disposed on the lower side of the insulating plate 2 and located to the right of the locking bolt 4. The first limiting plate 51 and the second limiting plate 52 are parallel to each other. Several elastic pressure plates 6 that can press onto the copper plate 3 are provided on the upper and lower sides of the limiting plate 5. This presses the copper plate 3 firmly into the slot 21, and the elastic pressure plate 6 creates continuous elastic pressure between the copper plate 3 and the limiting plate 5, preventing loosening due to vibration or temperature changes and ensuring a good and stable connection between the connecting device and the busbar. Meanwhile, the first limiting plate 51 and the second limiting plate 52 located on the left and right sides facilitate left-right alignment during installation.

[0024] In this design, there is a gap between the lower side of the first limiting plate 51 and the copper plate 3 located below it. The elastic pressure plate 6 includes a first elastic pressure plate 61 disposed on the lower side of the first limiting plate 51 and capable of pressing against the lower copper plate 3. There is a gap between the upper side of the second limiting plate 52 and the copper plate 3 located above it. The elastic pressure plate 6 includes a second elastic pressure plate 62 disposed on the upper side of the second limiting plate 52 and capable of pressing against the upper copper plate 3. There is a gap between the upper side of the first limiting plate 51 and the copper plate 3 located above it. The elastic pressure plate 6 includes a third elastic pressure plate 63 disposed on the upper side of the first limiting plate 51 and capable of pressing against the upper copper plate 3. There is a gap between the lower side of the second limiting plate 52 and the copper plate 3 located below it. The elastic pressure plate 6 includes a fourth elastic pressure plate 64 disposed on the lower side of the second limiting plate 52 and capable of pressing against the lower copper plate 3. This design facilitates the insertion of the copper plate 3 into the slot 21. Specifically, the limiting plate 5 is provided with a slot for inserting and fixing the elastic pressure plate 6. The protruding end of the elastic pressure plate 6 is an arc surface that bends inward, which can prevent the copper plate 3 from being scratched during installation and prevent the protruding end of the elastic pressure plate 6 from abutting against the surface of the copper plate 3 and hindering its installation. Furthermore, the elastic coefficient of the elastic pressure plate 6 can be selected according to the thickness of the copper plate 3 and the required clamping force, and it can be processed using conventional spring steel material.

[0025] Reference Figures 4 to 6In another embodiment of this solution, the limiting plate 5 further includes a third limiting plate 53 disposed on the upper side of the insulating plate 2 and located to the right of the locking bolt 4, and a fourth limiting plate 54 disposed on the lower side of the insulating plate 2 and located to the left of the locking bolt 4. The third limiting plate 53 is located to the left of the second limiting plate 52, and the fourth limiting plate 54 is located to the right of the first limiting plate 51. This allows the copper plate 3 to be more securely fixed in the slot 21, and the first limiting plate 51 and the fourth limiting plate 54, as well as the second limiting plate 52 and the third limiting plate 53, can cooperate with each other to limit the position of the insulating plates 2.

[0026] Similarly, there is a gap between the lower side of the third limiting plate 53 and the copper plate 3 located below it, and the elastic pressure plate 6 further includes a fifth elastic pressure plate 65 disposed on the lower side of the third limiting plate 53 and capable of pressing against the lower copper plate 3. There is a gap between the upper side of the fourth limiting plate 54 and the copper plate 3 located above it, and the elastic pressure plate 6 further includes a sixth elastic pressure plate 66 disposed on the upper side of the fourth limiting plate 54 and capable of pressing against the upper copper plate 3. There is a gap between the upper side of the third limiting plate 53 and the copper plate 3 located above it, and the elastic pressure plate 6 further includes a seventh elastic pressure plate 67 disposed on the upper side of the third limiting plate 53 and capable of pressing against the upper copper plate 3. There is a gap between the lower side of the fourth limiting plate 54 and the copper plate 3 located below it, and the elastic pressure plate 6 further includes an eighth elastic pressure plate 68 disposed on the lower side of the fourth limiting plate 54 and capable of pressing against the lower copper plate 3.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
