[0039] Capacitors are common electrical components in the power system, used for storing and releasing electrical energy. Capacitors are also indispensable components on the circuit board, and capacitors play a crucial role in the circuit board. First of all, capacitors have the characteristic of "blocking direct current and passing alternating current"; secondly, capacitors also have an energy storage function. It can be charged and store energy, and then transmit it to the output end of the power supply through the converter lead; in addition, capacitors also play roles such as decoupling and filtering in the circuit.

[0040] During the production process of capacitors, it is necessary to energize to test the stability and integrity of the capacitors, which will cause the capacitors to store electrical charges inside. When the capacitors with stored electrical charges are installed on the circuit board, it is easy to cause capacitor discharge short circuits, resulting in capacitor damage. Therefore, before use, it is necessary to discharge the capacitors. Existing discharge devices are mostly hand-held discharge devices.

[0121] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made.

[0122] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present application.

[0123] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
