[0010] The limiting ring is used to clamp the copper busbar limiting plate formed by TPU injection molding, which is convenient for limiting the electrode copper busbar.
[0011] Furthermore, the inner side of the limiting ring shrinks inward to form a clamping block, both ends of the copper bar limiting plate wrap the clamping block, and the electrode copper bar is fixed in the middle of the copper bar limiting plate by interference fit.
[0012] The clamping block that appears after the inner side of the limit ring shrinks inwards cooperates with the copper bar limit plate to complete the fixed installation of the copper bar limit plate, and the fixing effect is reliable.
[0013] Furthermore, the upper end of the positioning ring has multiple groups of positioning bosses.
[0014] The positioning boss on the positioning ring is matched with the housing to improve the positioning accuracy.
[0015] Furthermore, the positioning boss is fixed to the upper edge of the positioning ring through an adapter plate.
[0016] The positioning boss is fixed on the adapter plate, and the adapter plate is fixed to the positioning ring to complete the positioning installation.
[0017] Furthermore, the end of the positioning boss is a tapered structure.

[0027] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0028] See also Figure 1 The positioning ring 1 of this integrated blocking block is a ring structure supported by PC plastic, inside of which is an injection-molded TPU middle plate 2, the middle of the middle plate 2 is an electrode copper bar 3, the electrode copper bar 3 can be connected with the interface on the capacitor to be connected after extending, and there are blocking baffles 4 between the electrode copper bars 3 to avoid creepage between adjacent electrode copper bars 3.
[0029] See also Figure 2 An end plate 5 is fixed on the rear side of the positioning ring 1. The groove structure formed between the positioning ring 1 and the end plate 5 is convenient for injection molding of the intermediate plate 2 made of TPU material. At the same time, there are multiple through holes on the end plate 5. During the injection molding process of the intermediate plate 2, the material enters the through holes and forms a convex block stuck in the through holes after cooling, thereby improving the positioning effect.
[0030] See also Figure 1 and 3 The middle part of the positioning ring 1 is a raised limiting ring 6. The positioning ring 1 and the limiting ring 6 are integrally formed.

[0031] See also Figure 4 There is a card block extending inward on the inner side of the limit ring 6. When the copper bar limit plate 7 is injection molded, the TPU material forms a structure that wraps the card block after cooling, thereby improving the fixing stability of the copper bar limit plate 7.
[0032] See also Figure 1-3 The multiple positioning bosses 8 on the upper end of the positioning ring 1 are matched with the corresponding slots on the mounting capacitor housing. After docking, the positioning guide is completed to improve the structural stability of the blocking block after installation.
[0033] The positioning boss 8 is fixed on the positioning ring 1 through the adapter plate 9, and the positioning boss 8 is extended outward through the adapter plate 9 to meet the positioning and alignment requirements.
