AI Technical Summary
Due to the high ambient temperature on the aluminum substrate, the electrolytic capacitor is not resistant to high temperatures and cannot be directly welded, resulting in the need to use a relatively expensive solid-state capacitor, which increases the cost of the controller.
The electrolytic capacitor is welded by a transit plate and connected to the aluminum substrate through screws or welding to achieve electrical connection and replace solid-state capacitors.
This reduces production costs, realizes the possibility of using electrolytic capacitors, and avoids the problem of capacitor bursting in high temperature environments.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electronic components and relates to a structure for installing an electrolytic capacitor on an aluminum substrate. Background Art
[0002] The capacitors used in motor controllers are usually solid capacitors, which are expensive, thus increasing the cost of the controller. This is because when the SMD process is connected to the capacitor in the controller's aluminum substrate, the ambient temperature can reach 260 degrees during SMD. Electrolytic capacitors themselves are not resistant to high temperatures. The electrolyte will boil at around 160 degrees, causing the capacitor cavity to burst. Therefore, electrolytic capacitors cannot be directly welded on aluminum substrates. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0020] like Figure 1-3 As shown, a structure for mounting an electrolytic capacitor on an aluminum substrate includes a transfer plate 1 that can form an electrical connection with the aluminum substrate 100. The aluminum substrate and the transfer plate 1 are fixedly connected by screwing, welding or a pin socket. A capacitor 2 is welded on the transfer plate 1. The capacitor 2 is an electrolytic capacitor.
[0021] In the prior art, due to the influence of the aluminum substrate patch process, the ambient temperature can reach 260 degrees during patching. The electrolytic capacitor product itself is not resistant to high temperatures. The electrolyte will boil at about 160 degrees, causing the capacitor cavity to burst, so the electrolytic capacitor cannot be directly welded on the aluminum substrate. The existing aluminum substrate patch process is to weld solid-state capacitors, but the cost of solid-state capacitors is relatively high. In this application, the capacitor 2 is welded to the transfer plate 1, and the transfer plate 1 is connected to the conductive column by screws or welding. The conductive column is connected to the aluminum substrate by screws or welding. In this way, the solid-state capacitor is replaced by an electrolytic capacitor, thereby reducing the production cost.
[0022] Specifically, the aluminum substrate 100 is provided with binding posts and screw holes 3. The binding posts include three-phase binding posts 4 and positive and negative power supply binding posts 5.
[0023] There are three three-phase binding posts 4 and two positive and negative power supply binding posts 5.
[0024] In a preferred embodiment, the three-phase terminal 4 and the positive and negative power terminal 5 are respectively provided with a terminal step 6. The three-phase terminal 4 and the positive and negative power terminal 5 are directly welded to the aluminum substrate, and the terminal step 6 serves as a support for the control board.
[0025] The utility model adopts the transfer plate 1 for transition, that is, the electrolytic capacitor is first welded on the transfer plate 1, and then the transfer plate 1 is welded to the aluminum substrate to achieve electrical connection, thereby replacing the solid capacitor with the electrolytic capacitor and reducing the production cost.
[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
