Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption of a DC load switch, in particular to a shock absorption structure for a DC load switch. Background Art

[0002] In the current design of DC load switches, instantaneous mechanisms are usually used to operate the opening and closing of contacts. However, the contact system of load switches is generally large in size. In order to achieve instantaneous opening and closing, a large amount of energy is required. The vibration generated by this energy poses a risk of affecting the life of the mechanism.

[0003] Existing DC load switches typically use various methods, such as spring shock absorbers, rubber shock pads, or hydraulic shock absorbers, to mitigate the impact of impact on the internal mechanical structure. These methods can provide a certain degree of buffering, thereby reducing damage to the mechanical structure caused by the impact.

[0004] However, in actual applications, although conventional shock absorption methods such as traditional spring shock absorbers and rubber shock pads can play a certain buffering effect, when faced with the large impact force generated during high-speed switching, their energy absorption capacity and response speed are often difficult to achieve the expected effect, resulting in the spindle drive part being damaged due to insufficient impact absorption.
