Abstract
Description
Technical Field
[0001] This utility model relates to the field of grounding switch technology, specifically a portable grounding switch. Background Technology
[0002] A grounding switch is a switch used to connect the grounding part of a circuit. It can disperse a portion of the current when the circuit is under load, thereby preventing short circuits and ensuring the safety of workers.
[0003] However, existing grounding switches generate current in the stationary and moving contacts during use, causing their temperature to rise and thus increasing the risk of short circuits.
[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN220208817U discloses a combined grounding switch, comprising a base, a bracket on one side of the base, a moving contact on the bracket, an insulator on the base, and a stationary contact on the top of the insulator. The stationary contact includes a mounting portion and a contact portion, the mounting portion and the contact portion being integrally connected. A stationary contact piece is formed on the side of the contact portion facing the base, and a contact portion is formed at the bottom of the stationary contact piece that contacts the moving blade of the moving contact. A recess is formed at the upper end of the contact portion, and a current-guiding groove is formed in the recess. The width of the contact portion is greater than the width of the recess. By forming a recess at the upper end of the contact portion of the stationary contact and providing a corresponding current-guiding groove within the recess, a portion of the current is quickly discharged, reducing temperature rise and preventing damage to the stationary contact.
[0005] The aforementioned device uses the current-dispersing groove set in the stationary contact to disperse the current during use. However, the current-dispersing groove set in the stationary contact of the aforementioned device only disperses the current. When the grounding switch is damaged, the installation and maintenance are more complicated, which affects the operation of personnel and increases the risk of short circuit. Utility Model Content
