[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Depend on Figures 1 to 7 This utility model discloses a modular plug-in snap-fit busbar trunking connection and positioning structure, comprising a connection and positioning structure body 1, which is connected between a first busbar trunking 2 and a second busbar trunking 3. The connection and positioning structure body 1 consists of a first snap-fit plate 4, a second snap-fit plate 5, a plurality of conductive plates 6, and a limiting component 7. The conductive plates 6 are located between the first snap-fit plate 4 and the second snap-fit plate 5, and are spaced apart from the conductive bars on the first busbar trunking 2 and the second busbar trunking 3. The limiting component 7 is connected through the first snap-fit plate 4 to the second snap-fit plate 5. The first clamping plate 4, the second clamping plate 5, and the conductive plate 6 are provided. Several positioning rods 8 are fixedly provided on the side of the first clamping plate 4 near the second clamping plate 5. The positioning rods 8 slide through the conductive plate 6 and the second clamping plate 5. Elastic plate 9 and elastic plate 10 are fixedly provided on the side of the first clamping plate 4 and the second clamping plate 5 away from the conductive plate 6, respectively. The limiting component 7 is composed of a circular limiting plate 11, a connecting rod 12, and a strip limiting plate 13. The connecting rod 12 is fixedly connected between the circular limiting plate 11 and the strip limiting plate 13.
[0025] During installation, the connecting positioning structure body 1 is placed between the first busbar groove 2 and the second busbar groove 3, so that the conductive plate 6 is spaced apart from the conductive bars on the first busbar groove 2 and the second busbar groove 3. Then, the strip limiting plate 13 is rotated with a tool so that the strip limiting plate 13 is in contact with the side of the second elastic plate 10. At this time, the circular limiting plate 11 is in close contact with the side of the first elastic plate 9. The first elastic plate 9 and the second elastic plate 10 undergo a certain degree of deformation to achieve elastic pre-tightening, improve the tightness of the connection, and prevent loosening.
[0026] The first clamping plate 4, the second clamping plate 5, and the conductive plate 6 are all provided with strip-shaped through grooves 14 that match the connecting rod 12 and the strip-shaped limiting plate 13. The length and width of the strip-shaped through groove 14 are greater than the length and width of the strip-shaped limiting plate 13, so that the connecting rod 12 and the strip-shaped limiting plate 13 can pass through the strip-shaped through groove 14 during the assembly process of the connecting positioning structure body 1.
[0027] The conductive plate 6 and the second snap-fit plate 5 are provided with positioning holes 15 at the four corners that match the positioning rod 8, which can be connected to the positioning rod 8 to achieve auxiliary positioning and improve connection stability.
[0028] One side of the strip-shaped limiting plate 13 is threaded with a limiting screw 16. One of the elastic plates 10 has a limiting hole 17 that matches the limiting screw 16. The inner diameter of the limiting hole 17 is larger than the diameter of the limiting screw 16. After the strip-shaped limiting plate 13 is installed, the limiting screw 16 and the limiting hole 17 achieve auxiliary limiting to prevent the strip-shaped limiting plate 13 from deflecting on its own. Since the elastic plate 10 will deform to a certain extent after connection, the inner diameter of the limiting hole 17 is set to be larger than the diameter of the limiting screw 16 to facilitate the insertion of the limiting screw 16 into the limiting hole 17.
[0029] Several arc-shaped elastic elements 18 are welded between the elastic plate 9 and the first clamping plate 4, and between the elastic plate 10 and the second clamping plate 5, which can assist in elastic support.
[0030] The main body 1 of the connecting positioning structure is provided with a dust cover 19, and a number of limit buckles 20 are fixedly provided on the dust cover 19. The first buckle plate 4 and the second buckle plate 5 are provided with a number of limit slots 21 that match the limit buckles 20. When the busbar is installed horizontally, the dust cover 19 is located at the top and can play a role in dust prevention. When the busbar is installed vertically, it can also play a role in safety protection.
[0031] In operation, by setting up a first snap-fit plate, a second snap-fit plate, a conductive plate, and a limiting assembly consisting of a circular limiting plate, a connecting rod, and a strip-shaped limiting plate, a snap-fit connection can be achieved, improving the convenience and stability of the connection. By setting up elastic plate one and elastic plate two, elastic pre-tightening can be achieved, improving the tightness of the connection and preventing loosening that could lead to poor contact. By setting up positioning rods and positioning holes, auxiliary positioning functions can be achieved, further improving the stability of the connection. By setting up limiting screws and limiting holes, the strip-shaped limiting plate can be auxiliaryly limited to prevent it from deflecting. By setting up arc-shaped elastic elements, elastic support can be further achieved. By setting up dust covers, dust prevention can be provided.
