[0030] like Figures 1 to 3 As shown, the branch busbar contact seat assembly structure according to an embodiment of the present invention includes:
[0031] The contact finger mounting seat 100 is tubular, and the contact finger mounting seat 100 is provided with an inserting pipe 110. The outer wall of the contact finger mounting seat 100 is in an arc shape arched from both ends to the middle, and an annular first spring contact finger mounting groove is provided in the inserting pipe 110. The first spring contact finger mounting groove is provided with a first spring contact finger 200, and the inner diameter of the first spring contact finger 200 is smaller than the inner diameter of the inserting pipe 110;
[0032] The contact base 300 has an assembly hole 310, one end of the assembly hole 310 is provided with an insertion port, and the other end is provided with a baffle 320, an arc groove matching the outer wall of the contact finger mounting base 100 is provided in the assembly hole 310, and a ring-shaped second spring contact finger mounting groove is provided at the bottom of the arc groove, and a second spring contact finger 400 is provided in the second spring contact finger mounting groove, and the contact finger mounting base 100 is installed in the arc groove, and the outer wall of the contact finger mounting base 100 is in contact with the second spring contact finger 400.
[0033] like Figure 4 As shown, when the conductor 800 is inserted into the first spring contact finger 200 during the insertion process of the pipe 110, the first spring contact finger 200 will clamp the conductor 800 inserted therein. As the conductor 800 continues to be inserted, the conductor 800 will drive the contact finger mounting seat 100 to slide on the arc groove of the contact seat 300 along the insertion direction, sharing part of the gravity and thrust from the conductor 800, thereby relieving the pressure of the first spring contact finger 200, avoiding excessive deformation of the first spring contact finger 200, and thus ensuring the contact and conductive performance of the first spring contact finger 200.
[0034] In addition, when the contact finger mounting seat 100 slides on the arc groove along the insertion direction, the second spring contact finger 400 installed in the second spring contact finger mounting groove will not be deformed due to the sliding of the contact finger mounting seat 100, and basically maintains the initial state, thereby ensuring the contact and conductive performance of the second spring contact finger 400.
[0035] In some embodiments of the present invention, two mounting seats 500 are fixedly provided in the assembly hole 310. The mounting seat 500 is an annular structure. One end of the inner wall of the mounting seat 500 is a thin end, and the other end is a thick end. The inner wall of the mounting seat 500 is arc-shaped from the thin end to the thick end. The thin ends of the two mounting seats 500 are arranged opposite to each other, and the inner walls of the two mounting seats 500 together form an arc-shaped groove. The second spring contact finger mounting groove is arranged between the two mounting seats 500.
[0036] In some embodiments of the present invention, the arc groove is formed by two mounting seats 500. Specifically, during the production process, the assembly hole 310 only needs to be processed into a regular cylindrical hole structure, and this processing method is relatively simple. Of course, the arc groove can also be directly processed in the assembly hole 310. Obviously, this processing difficulty is greatly increased, and the processing cost is relatively high, but the reliability will be better. The mounting seat 500 only needs to be processed separately, and during use, the mounting seat 500 can be installed in the assembly hole 310, which reduces the processing and production costs.
[0037] In some embodiments of the present invention, a limit stop block 600 is provided in the assembly hole 310, and the limit stop block 600 is arranged close to the insertion port, the mounting seat 500 close to the baffle 320 abuts against the baffle 320, and the mounting seat 500 close to the limit stop block 600 abuts against the limit stop block 600.
[0038] In this embodiment, the two mounting seats 500 are limited by the baffle 320 and the limit block 600, and the thick ends of the two mounting seats 500 are respectively abutted against the baffle 320 and the limit block 600 to prevent the two mounting seats 500 from sliding and moving due to the sliding of the contact mounting seat 100 during the insertion of the conductor 800.
[0039] In some embodiments of the present invention, the limit stopper 600 is a clamping ring structure, a limit stopper installation groove is provided in the assembly hole 310, and the limit stopper 600 is clamped in the limit stopper installation groove.
[0040] By setting in the limit stopper installation groove, the limit stopper 600 is clamped in the assembly hole 310 through the limit stopper installation groove. Specifically, after completing the installation of the two mounting seats 500, the limit stopper 600 is clamped in the limit stopper installation groove to complete the installation work of the mounting seat 500.
[0041] In some embodiments of the present invention, two insulating rings 700 are disposed in the insertion pipe 110 . The two insulating rings 700 are disposed on both sides of the first spring contact finger 200 . The inner diameter of the insulating ring 200 is not less than the inner diameter of the first spring contact finger 200 .
[0042] Under normal circumstances, the conductor 800 achieves contact conduction by contacting with the first spring contact finger 200 at multiple points. In order to prevent the conductor 800 from directly contacting the inner wall of the insertion pipe 110 and causing a short circuit due to excessive deformation of the first spring contact finger 200, the insulating ring 700 is provided so that even if the first spring contact finger 200 is deformed, the conductor 800 will not directly contact the inner wall of the insertion pipe 110, thereby isolating the possibility of direct contact between the conductor 800 and the inner wall of the insertion pipe 110.
[0043] In some embodiments of the present invention, two insulating ring installation grooves are provided in the insertion pipe 110, and the two insulating ring installation grooves are arranged on both sides of the first spring contact finger installation groove, and the two insulating rings 700 are respectively installed in the corresponding insulating ring installation grooves. The insulating ring 700 is installed in the insertion pipe 110 through the insulating ring installation groove, and the insulating ring 700 and the contact finger mounting seat 100 are produced independently, which helps to reduce the production process and reduce the production cost. After the production is completed, the insulating ring 700 is clamped in the insulating ring installation groove.
[0044] Furthermore, the insulating ring 700 is an elastic ring body, and the insulating ring 700 is provided with an opening. When the insulating ring 700 is clamped in the insulating ring installation groove, since the insulating ring 700 is provided with an opening, by applying pressure to the insulating ring 700, the insulating ring 700 will shrink, and the insulating ring 700 can be placed in the insulating ring installation groove. After that, the pressure is removed, and the insulating ring 700 returns to its original shape, and the clamping operation is completed.
[0045] In some embodiments of the present invention, the baffle 320 is provided with a plurality of through holes 321 communicating with the assembly hole 310 for installing other circuit devices.
