Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative work belong to the scope of protection of the present utility model.

[0023] An insertable contact mounting base is used to install and fix the busbar 5 and the busbar contact 7. A number of busbars 5 are fixedly arranged in one mounting base, and the busbars 5 are arranged and fixed in the mounting base in sequence.

[0024] As Figures 1 - 4 shown, the mounting base includes a main body 1. Symmetrically distributed mounting plates 6 are fixedly arranged on the busbar 5, and bolts for fixing the busbar 5 are connected to the mounting plates 6.

[0025] The main body 1 is composed of two mounting shells 9 spliced and installed. A number of mounting grooves are arranged in the main body 1 for accommodating the busbar contacts 7. The busbar contacts 7 are located at one end of the busbar 5. A through groove 12 is opened on one side of the mounting shell 9, and the busbar 5 passes through and is installed in the through groove 12. Straight grooves are opened on both sides of the through groove 12, and both the straight grooves and the through groove 12 are located on one side of the mounting groove.

[0026] The straight grooves are respectively arranged on the upper and lower sides of the through groove 12 in the same mounting groove for fixing the mounting plate 6. The bolts pass through the mounting plate 6 and the straight grooves and are connected to nuts, which is convenient for locking the busbar 5, so that the busbar contact 7 is installed and fixed in the mounting groove.

[0027] Heat dissipation grooves 3 are opened on the mounting shell 9 for discharging the heat in the mounting groove. An interleaved channel structure 10 is arranged between two adjacent mounting grooves. A fixing block 2 is fixedly arranged on the side of the mounting shell 9 away from the through groove 12. The fixing block 2 is located between two adjacent mounting grooves, and a sliding groove is opened on the fixing block 2. A threaded hole is arranged at the end of the fixing block 2. Mounting holes 4 are opened on the side surface of the mounting shell 9. Screws pass through the mounting holes and are connected to the threaded holes on the fixing block 2 to lock the two mounting shells 9.

[0028] The fixing blocks 2 on the two mounting shells 9 are mutually attached to support the structure of the mounting groove between the two mounting shells 9. An insulating partition 11 is slidably installed in the sliding groove. The insulating partition 11 is located on the side of the mounting groove away from the through groove 12. A rectangular groove 8 is opened on the insulating partition 11 for installing a power-taking structure connected to the busbar 5.

[0029] Positioning holes 13 are arranged on the outer side of the mounting shell 9, and positioning blocks 14 are arranged on the outer side of the mounting shell 9.
